Description

DETAILED DESCRIPTION OF THE INVENTION The present invention continuously removes scrap generated when cutting both ends of a cold-rolled strip steel plate with a side trimmer in order to adjust the width dimension to a required dimension. In a scrap press, which is used to process scraps into lumps of a certain size and make them easier to transport, this machine cuts continuously incoming scraps and compressed scraps in a short period of time, allowing subsequent scraps to be processed. This is to prevent any hindrance.

As shown in FIGS. 1 and 2, a conventional scrap press of this type has a lower cutting edge attached to the tip of the upper surface of the primary suppressing plate a, and an upper part of the pushing limit of the primary suppressing plate a. The upper blade C is fixed on a tool rest f which is provided at the entry side of the press chamber d so as to be movable up and down by a fluid pressure cylinder e.

Therefore, when cutting scrap, after the first pressing, the gap between the upper blade C and the lower blade is maintained by inserting the upper blade C into the upper blade guide g provided on the 1st depression plate a. Ta.

However, in the conventional device described above, accidents often occur in which scrap gets into the upper blade guide g, making it impossible to cut the scrap.

For this reason, even if the scrap lumps after pressing are sent out onto a conveyor belt, they are still connected and pulled by the linear strips, resulting in disadvantages such as accidents such as the scrap lumps falling off the conveyor. It had

The present invention has been made to solve the drawbacks of the above-mentioned conventional devices, and includes a lower blade provided on the front upper surface of the primary pressing plate, and
A scrap press characterized by having a frame movably formed integrally fixed to the pressing plate, and an upper blade which can be raised and lowered at a position facing the lower blade at the front end of the frame. It is.

The present invention will be described in detail below with reference to the drawings.

As shown in FIGS. 3 to 8, in a scrap press having a primary pressing chamber 1, a secondary pressing chamber 2, and a press chamber 3,
The primary pressing plate 4 is disposed in the primary pressing chamber 1 so as to be able to slide back and forth without a gap, and is attached to a pin at the fork end 10 at the tip of the piston rod 9 of the fluid pressure cylinder 8 fixed to a mounting base on the base 13. 11 are connected.

A U-shaped frame 5 is fixed to the upper part of the primary suppression plate 4 so as to avoid the hopper 32.
On the upper surface of the front end, there is a rotatable upper blade 6 and an upper blade 6 for cutting.
An upper blade guide 7 is provided to guide the positioning of the blade.

Further, the upper blade 6 is attached to an upper blade mount 25 which is rotatably connected to the bracket 12 attached to the tip of the frame 5 by fitting on a pin 24. has an arm portion 26 extending rearward, and the arm portion 26 is attached to a fork at the tip of a piston rod 29 of a fluid pressure cylinder 28 that is swingably attached to a bracket 27 fixed to the lower surface of the rear end of the frame 5. It is connected to the end 30 by a pin 31.

In addition, a lower blade 14 for a scrap cutter is attached to the upper surface of the front end of the primary pressing plate 4 via a lower blade mount 15, and a plate 16 for preventing scrap from entering is placed close to the lower blade 14. It is set up as follows.

The plate 16 is fitted onto a shaft 17 rotatably supported at both ends of the primary pressing plate 4 and fixed to a lever 18 which rotates together with the shaft 11.

A lever 19 is fixed to the shaft 17, and a fork end 22 at the tip of the piston rod 21 of the hydraulic cylinder 20, which is swingably supported by the rear part of the primary suppression plate 4, is connected between the lever 19 and the fork end 22 at the tip of the piston rod 21 of the hydraulic cylinder 20, which is swingably supported. They are connected by a pin 23.

Next, the operation when cutting scrap with the scrap cutter having the above configuration will be explained.

First, the fluid pressure cylinder 2B in FIG. 7 is contracted and raised to the imaginary line position, and then the fluid pressure cylinder 8 in FIG. 6 is contracted to move the primary suppression plate 4 from the solid line position to the imaginary line position. It is moved backward and scraps are accumulated in the first containment chamber 1.

At this time, the upper blade 6 and lower blade 14 for cutting the scrap also move integrally with the primary pressing plate 4 and are in the retracted position.

When the primary pushing chamber 1 is filled with scraps, the hydraulic cylinder 8 is extended and the primary suppressing plate 4 pushes the scraps into the secondary pushing chamber 2.

At this time, since the scraps continuously enter in a linear manner, the scraps in the secondary pushing chamber 2 and the scraps in the hopper 32 are connected.

Therefore, as shown in FIG. 7, by extending the hydraulic cylinder 28 connected to the upper blade mounting base 25 and lowering the upper blade 6 as shown by the solid line, the upper blade 6 is connected to the lower blade 14. Cut the scraps.

At this time, the plate 16 shown in FIG. 6 is pushed down by the upper blade 6 and returns to its original position when the upper blade 6 rises after cutting, so scraps enter below the lower blade 14. Mechanically prevent this.

Furthermore, in the above configuration, the upper blade 6 and the lower blade 14 are integrally attached so as to move together with the primary pressing plate 4, so that cutting can be performed reliably without any change in relative position. be exposed.

It should be noted that the present invention is not limited only to the above-mentioned embodiments, and that the shape of the frame and the mounting position to the primary suppression plate are not limited to those shown in the drawings, and that it can be applied to other types of scrap presses. It goes without saying that the shape of the constitutive valley is not limited to that shown in the drawings, and that various other changes may be made without departing from the gist of the vehicle invention.

According to the above-described scrap press of the present invention, (1) since the relative positions of the upper blade and the lower blade remain unchanged, the positions can be easily set.

(11) Since scrap does not enter the upper blade guide unlike in the conventional case, there is no possibility that cutting becomes impossible.

(＋＊＋) Maintenance and inspection are easy because part of the cutter is external.

etc., exhibits various excellent effects.
