Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tri-press machine having one press machine and a plurality of profile correction lines.

The try press machine is used to make a press mold, then test it and repair any defective parts.

By the way, with conventional tri-press equipment, the mold is corrected while it is fixed to the press equipment, so during the time-consuming correction work, the press slide only serves as a crane to separate and hold the upper mold from the lower mold. Therefore, the expensive press equipment cannot perform its original function during that time, so the operating rate of the press equipment is extremely low.
It was extremely inefficient when cutting out shapes that required a large number of trial shots. The present invention has been made in order to eliminate the drawbacks of the conventional ones described above, and includes an upper die correction section and a lower die correction section separate from the press equipment, and the mold material after the tri-press is corrected in the respective sections. , play 10 again
so that it can be brought into the space equipment and used for try-pressing.
A suitable rail is laid, and under a mechanism in which a moving bolster for transporting the shape material is self-propelled on the rail, the modification of the try press and lower mold is carried out until step 15 while the shape material is placed on the moving bolster. The upper mold correction section is equipped with a die setter device to lift the upper mold and send the lower mold to the next lower mold correction section, and a turntable is interposed on the rail, so that it is composed of both the rail and the upper and lower mold correction sections. This device 20 allows the required number of shape material correction lines to be set, thereby providing a try press device with high operating rate and work efficiency.

Hereinafter, the present invention will be specifically described based on an embodiment shown in the drawings.
One of them will be explained in detail.

In Fig. 1, there are two parallel main rails 6 laid at 25 including the inside of the gate of the press device 1, and two parallel rails laid including the upper die correction section 2 and the lower die correction section 3. First rail 1a) Second rail Tb) Third rail Tc
and can be connected to each other by means of a turntable 8 on which rails are laid in one direction.

Of course, these rails are parallel set rails. Hereinafter, the paired mold correction sections of the upper and lower molds and their rails will be collectively referred to as the mold correction line. Thus, bogie-shaped moving bolsters 4 are arranged on the base 35 trunk rails 6 and on each correction line, respectively.

As shown in FIG. 2, the press device 1 is equipped with a press slide 11 that moves up and down by the power of hydraulic pressure, compressed air, etc. between frames 10 set up at the four corners, and a gate straddle formed by the frame. A main rail 6 is installed on the floor 12 inside. At the stop position M of the moping bolster 4 in the press device (see FIG. 2), the rail supporting the wheels of the bolster is configured to be lowered by a cylinder (not shown). is lowered and is supported in contact with the upper surface of the floor 12. A clamper 13A is provided on the lower surface of the floor 12, and its shaft is projected upward by the biasing force of a solenoid energized by an operator's command, thereby restraining the moping bolster 4 from moving in the horizontal direction. Reference numeral 5 denotes a mold material, the lower mold 51 of which is fixed to a lower adapter plate 52 with bolts, and the adapter plate is placed and fixed on the base of the moping bolster 4.

The upper mold 53 is placed facing the lower mold 51, and an upper adapter plate 54 is fixed to the back surface thereof with bolts.
A plurality of auto clampers 14A shown in FIG. 5 are arranged on the lower end of the press slide 11, and the clamp rods 15A having hooks at the tips are operated by an operator using a button switch, etc., as shown in the arrow directions A and B. The rod 15A can be rotated vertically and outwardly as shown in FIG.
is positioned vertically, the upper adapter plate 54
The auto clamper 14A holds the upper adapter plate 54 by engaging with a notch 55 (see FIG. 6) provided on the side surface of the upper adapter plate 54, and can lift it by raising the press slide 11. Note that the lower adapter plate 52 is also provided with a notch, which is used for fishing in other cases. Next, the mold correction line will be explained. Since each of the correction lines has substantially the same shape, only the first correction line including the first rail 7a will be described here, and the description of the other correction lines will be omitted. Upper mold correction section 2
A die setter device 20 shown in FIGS. 3 and 4 is provided.

This die setter device 20 is provided with a pair of opposing beams 24 that can be raised and lowered by the rotation of a threaded rod 22 along pillars 21 erected at the four corners. A plate 26 is provided between the beams and is configured to be able to be turned upside down. In addition, this plate 26
can be stopped at any angle between the up and down inversions and maintain its tilted state. Although the plate 26 is shown in its full width in FIG. 4, it is hidden behind the beam 24 in FIG. It is shown. Thus, the threaded rod 22 is rotated by a motor 23 on a beam plate suspended over the earth part of the column 21, and the plate 26 is rotated by a motor 27 provided on the beam 24 via a worm gear device 28. be moved.

A plurality of auto clampers 14B (see also FIG. 5) of the same type as those provided in the press device 1 are provided at the side ends of the plate 26, and a stopper 29 is provided to protrude downward from one side of the lower surface.

Also, a stopper 1 is provided on the bottom surface of the floor of the dice setter device 20.
3B is provided, and the movement of the moping bolster 4 can be automatically restrained by protruding the shaft rod of the stopper into the floor soil. Incidentally, the clamp rod 15B of the auto-clamp 14B is shown in FIG. Next, lower mold correction section 3
, a stopper 31 is provided at the end of the first rail 7a, and a limit switch (not shown) automatically stops the moping bolster 4 at a normal position and restricts its movement.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but may be partially replaced as long as it is based on well-known technology that satisfies the required functions.

For example, the lifting and lowering of the beam 24 in the die setter device 20 may be performed using another suitable lifting mechanism that uses hydraulic pressure, air pressure, etc., the cutouts 55 of the auto clampers 14A and 14B1 may be formed using an electromagnetic attraction mechanism, and the stoppers 13B and 31 In the die setter device 20, which handles only special shapes that do not require reversing or tilting of the upper die, the plate 26 may be eliminated and the upper die lifting mechanism may be provided directly on the beam material 24. , and the number of modified lines,
It is within the scope of the present invention to increase or decrease the number of turntables and moving bolsters as required.
Since the device of this embodiment is constructed as described above, even if the press device 1 is located in a place where two or three sides cannot be used due to a partition wall, a support in a factory, other installed equipment, a passage, etc., the press Installation of the device 1 is possible.

Although the loading and unloading of profile materials to the moping bolster 4 is generally carried out by a factory crane, it is most preferable to carry out loading and unloading, for example, on the main rail 6 in front of the press apparatus 1 in terms of the arrangement of the bolster 4.
However, the loading and unloading location should be determined in conjunction with the existing or new crane suspension rails.
The reality is that it is quite difficult to achieve what you want.

In this respect, in this device, the turntable itself and the rails of each correction line around it are under almost the same conditions as the main rail 6, so there is a great degree of freedom in selecting loading and unloading positions.

Now, after placing the profile 5 on the moping bolster 4 and fixing its lower adapter plate 52 to the base, the bolster 4 is allowed to move forward to the press stop position of the press device 1, as shown in the figure. The limit switch is activated to automatically stop the bolster 4, and the clamper 13A is activated to restrain the horizontal movement of the bolster 4.

When the press slide 11 of the press device 1 is operated downward and the lower surface of the press slide 11 comes into contact with the upper adapter plate 54, a limit switch (not shown) is activated to stop the press slide 11 from descending. auto clamp 14
After the clamp rod 15A is engaged with the notch 55 of the upper adapter plate 54 by driving the press slide 11, the press slide 11 is raised and stopped at an appropriate position.

A workpiece, for example, a sheet metal, is placed and set by a worker on the mold surface of the lower mold 51 on which the upper mold 53 is lifted. Next, the press device is operated to perform a trial press (try press).

The press slide 11 is placed in the raised position again, and the operator inspects the workpiece. If a defect in the workpiece due to a defect in the mold material 5 is found, the worker sends the mold material to a repair line. That is,
The worker removes the workpiece if necessary and presses slide 1.
1 to the lowered position again, the auto clamper 14A is removed, and the upper die 53 is released onto the lower die 51. After releasing the clamper 13A, the bolster 4 is driven by itself, passes through the main rail 6 and the turntable 8, enters the rail of a predetermined correction line, and is stopped at a predetermined position in the die setter device 20 of the upper die correction section 2 by the action of a limit switch (not shown). . At the same time, the stopper 13B operates to restrict movement of the bolster 4.

) In the above, there are a total of 4 rails on each line as shown in Figure 1.
If the bolsters 4 are overcrowded, such as when the bolsters 4 of the platform are arranged, it is possible that an empty bolster 4 already exists on the correction line that is about to be corrected. The bolster of the load may be evacuated in advance onto a rail near the turntable 8 on another correction line, and the possibility of such a bolster replacement operation can be cited as one of the benefits of the turntable.

The moving bolster 4 is placed in a predetermined position of the die setter device 20.
Once set, the worker drives the motor 23 to lower the beam 24 through the rotation of the threaded rod 22.

When the plate 26 comes into contact with the upper adapter plate 54 of the profile, a limit switch (not shown) is activated and the beam 24
The descent will stop automatically. After driving the auto clamper 14B to engage the clamp rod 15B with the notch 55 of the upper adapter plate 54, the beam 24 is raised to lift the upper die 53, and the motor 27 is driven to lower the plate 26. Rotate counterclockwise, reverse and stop. During this plate reversal operation, the upper adapter plate 54
For details, see auto clamper 14B1.For details, see clamp rod 15.
Although the auto clamper 14B is supported by B, the auto clamper 14B does not have enough strength to support the weight of the upper adapter plate 54 with the upper mold 53, so the stopper 29 prevents the weight from sliding. In this way, the beam material 24 is lowered and held at an appropriate position, and the upper mold 53 whose mold surface is facing upward can be corrected, so the correction is much easier than in the case of the conventional tri-press (mold surface facing downward). Easy to work with.

Note that, depending on the mold or the operator's preference, if it is preferable for the mold surface to be tilted toward the soil, the plate 26 can be tilted and stopped at a required angle. After releasing the stopper 13B, the bolster 4 carrying the lower mold 51 is sent to the next lower mold correction section 3 by itself. The moping bolster 4 that has been self-propelled to the lower mold correction section 3 comes into contact with the stopper 31 and is automatically stopped by a limit switch (not shown). If a workpiece is placed thereon, after removing the workpiece, the lower die 51 is corrected on the bolster 4. The removed workpiece is placed near the correction area and can be viewed at any time as a reference material for correction if necessary. Therefore, if the lower mold 51 is corrected while it is placed on the bolster 4, the height thereof is not only more suitable for the correction work, but also the work procedure is simplified and efficient. As described above, the present invention enables a required number of shape material correction sections to be connected to one press machine by means of a rail with a turntable interposed therebetween. As a result, the operation rate of the press equipment can be increased, and work efficiency can be improved by making corrections to both the soil mold and the lower mold with the mold surfaces facing upward, and corrections to the try press and the lower mold can be made. In addition to simplifying the work procedure by allowing the work to be carried out with the lower die fixed on the moving bolster, we also streamlined the arrangement of work compartments and applied automation and semi-automation to each work procedure. The company was able to provide an excellent tri-press device that enabled smooth, reliable, and highly efficient work progress.
