Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a die changing device for a press.

Conventionally, in a system in which two carts were run parallel to each other along the front of the press, that is, a mold take-out cart and a mold supply cart, the one farthest from the die room of the press was The trolley requires a mechanism to run in the direction of the die room of the press and bring it closer to the die room of the press, and has the disadvantage that a complicated configuration and operation method are required in relation to the rail of the trolley closer to the die room. Ta.
The present invention has been made to solve such problems. Hereinafter, the present invention will be explained based on drawings which are one embodiment.

1 and 2, carts 3 and 4 run parallel to each other along the die room 2 of the press 1.
Rails 5 and 6 are laid on the floor. The rail 7 is a running body 49 provided on the trolley 4, which will be described later.
It is a rail for.

In this embodiment, the rails 5, 6, and 7 are provided near the front of the press. A mold loading/unloading device 8 is provided behind the die room 2 of the press. The mold loading/unloading device 8 moves the used mold from the die room of the press onto the mold take-out cart (cart 3 in this embodiment), and transfers the mold to be used next to the mold. Its role is to move it from the supply truck to the die room of the press.

In this embodiment, since a transfer press is used, the feed bar 10 is also replaced together with the mold.

In FIG. 3, FIG. 4, and FIG. 5, the wheel 11
is provided on the truck 3, and is driven by a motor 12 provided on the truck 3 via a sprocket, a chain, etc. The rail 13 is fixedly installed on the upper part of the truck 3, and rollers are appropriately provided thereon, on which the mold moves. The rollers 18 are fixedly installed on the upper part of the truck 3 and guide the molds on the rails 13. The pin 14 is provided on the upper part of the cart 3 so as to be able to rise and fall freely, and is moved up and down by a lever 15 and a handle 17 connected thereto, and serves to position the mold and stop it from moving. The lever 15 is automatically pushed down by the cylinder 16 on the front of the press 1, and the pin 1 is pushed down accordingly.
4 goes down. A mold is placed on the trolley 3, and while the cart 3 is running, the pins 14 are raised by springs and engaged with both the front and rear sides of the mold. The reel 19 is provided on the trolley 3 and serves to wind up or unwind the electrical wiring.

In FIGS. 6, 7, and 8, the cart 4 is provided with wheels 20 similarly to the cart 3, and the cart 4
The motor 21 installed in the sprocket,
Driven through a chain or the like. The truck 4 is provided with a running body 49 that carries the mold and runs on the truck 4. The traveling body 49 is composed of a rail 22 on which the mold is placed, and is driven by a motor 29 provided on the truck 4.

6 to 10, a sprocket fixed to the output shaft of the motor 29 is connected by a chain to a sprocket 30 rotatably held on the truck 4 via a trilimiter. A chain 32 is provided in the lower part of a movable body 33 that is slidably guided on the truck 4 and faces in the front-rear direction, and this chain 32 meshes with a sprocket 31 that is fixed to the shaft of a sprocket 30. .

The sprockets 34, 35 are rotatably held by the movable body 33, and a chain 36 is attached to the sprockets 34, 35. The chain 36 is secured to a bracket 37 fixed to the trolley 4, and
It is also locked to a bracket 38 that is fixed to the connecting member 23 that connects the two rails 22, 22.

In FIGS. 7, 8, and 11, the rail 28 is fixed to the trolley 4, and the running wheels 26, 27
A running body 49 having a running body 49 runs on this. feet 24
are fixed to the press 1 side of the lower surface of the rail 22 of the running body 49, and have running wheels 25 at the bottom. Wheels 25 run on rails 7.

That is, the traveling body 4 is driven by the motor 29 from the cart 4 stopped in front of the die room 2 of the press 1.
When the vehicle 9 travels toward the die room 2, the wheels 25 come onto the rail 7 before the wheels 27 come off the rails 28. Running body 49
is a mechanism that moves by twice the amount of movement of the moving body 33, and the amount by which the moving body 33 protrudes from the cart 4 is small, so that the distance between the carts 3 and 4 can be small.

In addition, the trolley 4 and its running body 49 have rollers 18, pins 14, handles 17,
A lever 15 and the like are provided. However, the pins and the like are provided at the upper part of the foot 24.

In FIGS. 12 to 15, a motor 39 is provided behind the die room of the press.
The sprocket of the output shaft of the press 1 and the sprocket 40, which is rotatably held with respect to the press 1 via a torque limiter coupling, are connected by a chain. The sprocket 41 is fixed to the shaft of the sprocket 40, and the sprocket 42 is connected to the sprocket 41.
A chain 43 is provided between sprockets 41 and 42 at regular intervals.

The moving member 44 is slidably guided with respect to the press 1 and is locked to the chain 43.
That is, the moving member 44 moves as the chain 43 moves. The cylinder 45 is rotatably held by a moving member 44, and its piston rod is rotatably connected to a link 47, so that the rod 50 is rotated 90 degrees via a link 46. The engaging member 48 is provided at the tip of the rod 50, and is detachable from the mold by the action of the cylinder 45.

The effect will be explained below.

In Figure 1, when the press work is completed,
The truck 3 travels to the front of the press 1. The cylinder 16 is lowered and the lever 15 of the truck 3 (Fig. 5)
push down. Along with this, the pin 14 descends. A moving member 44 of the mold loading/unloading device 8 pushes out the used mold in the die room of the press onto the carriage 3. By raising the lever 15 using the cylinder 16, the pin 14 is raised and the mold is positioned. In the figure, the trolley 3 travels to the right and returns to its original position. The trolley 4 carries the mold to be used next and travels to the front of the press. In FIG. 6, a traveling body 49 is driven by a motor 29 to travel toward the die room of the press. In this case, in FIG. 8, the wheel 25 is on the rail 7 before the wheel 27 comes off the rail 28. The traveling body 49 and the mold thereon first travel on the rail 28 using wheels 26 and 27, and then travel using wheels 26 and 25. When the traveling body 49 comes to the fixed position, the cylinder 16 is lowered and the pin 14 is lowered via the lever 15, so that the mold can move on the rail 22. In this state, the mold loading/unloading device 8 retreats, and the rail 22
The upper mold is drawn into the die room of the press. After the cylinder 16 is raised, the traveling body 49 is made to travel to its original position, and the truck 4 is made to travel to the right in FIG. 1 and returned to its original position. A conventional clamper is used to slide the mold and tighten it to the bolster.

Since the present invention has the above-described configuration, there is no mechanism for moving the cart 4 toward the die room of the press, so the structure of the rails on the front side of the press is simple, easy to install, and easy to install. It is also possible to assemble it into the press later.
