Abstract

PURPOSE:To improve the operational efficiency by applying a powerful pressing force corresponding to the cutting force of a cutting machine onto a scrap material thereby increasing the bulk specific gravity and shortening the reset process. CONSTITUTION:A press board 3 will move downward to the position where the cutting root section of a scrap material (a) is stopped by pressing, then a cutting cylinder will function to move a cutting board 4 downwardly thus to cut the pressed scrap material (a). Following the cutting, an engaging chip 4 in said board 4 will contact and engaged with a press board 3 to transmit the pressing force corresponding to the cutting force of the cutting board 4 integrally onto the press board 3. Upon moving upward said board 3, the cutting board 4 is reset automatically to initial position.

Description

[Detailed description of the invention] The present invention aims to speed up the cutting process of metal scrap materials,
The present invention relates to a scrap material compression cutting device that has significantly improved cutting efficiency, is highly durable and robust, and has extremely simplified maintenance work.

Conventionally, this type of device (in two cases) used a feeding cylinder to extend the scrap material to a required length from the bottom of the case frame, and then press the base of the scrap material by moving the press plate of the press cylinder forward. Then, the cutting plate of the cutting cylinder is moved forward to cut and separate the scrap material in the overhanging portion, and after that, the press cylinder and cutting cylinder are moved back to separate the press plate and cutting plate, respectively. A device configured to complete the cutting process by returning separately and independently is generally used (= used, but the device W1 (
Second, since the cylinders for pressing and cutting have no relation to each other in terms of operation and power, the cutting process (2) not only takes a long time and is inefficient, but also wastes power. In addition, the scrap material after cutting has a small bulk specific gravity, making it difficult to transport.Also, in the above-mentioned equipment, the press plate or cutting plate is Since the vertical (two vertical direction) guided by the vertical (two sliding) structure is generally used, the rotational moment about the shearing part that acts on the cutting machine during shearing is reduced. While supporting the sleeve, the surface of the cutting board strongly contacts the surface of the sleeve and slides on it by friction, which causes severe wear and damage to the sleeve and the cutting board.Maintenance thereof not only requires a lot of cost and manpower, but also requires a lot of labor. There were a number of drawbacks, such as the kinetic energy of the disk equivalent to the amount of mechanical energy was wasted (double wasted), reducing the operating efficiency of the cylinder.

The object of the present invention is that after the cutting machine cuts the scrap material, the cutting machine engages with the press machine and a strong compressive force corresponding to the cutting force of the cutting machine is generated naturally (niveless machine). The bulk specific gravity of the scrap material is greatly reduced by strongly compressing it, and the cutting cylinder is automatically returned to its original position in conjunction with the rapid movement of the press cylinder during the return operation, thereby shortening the return process. Increasing efficiency and saving cylinder power C: In addition to contributing, the rotational moment that acts on the cutting board during shearing (two) is supported on a vertical line approximately at the center of the cutting board, thereby reducing the axis angle of the cutting board. The purpose of this invention is to provide a small-sized scrap material compression cutting device that is capable of reliably cutting the metal scraps into single pieces. Pressing plate (in the cutting side direction of the frame from the second side (-in the extending direction and cutting device, the press plate C of the press cylinder located above the end of the case frame, adjacent to the extending direction of the case frame) □The cutting plate of the adjacent cutting cylinder can be freely engaged and separated from above (= constituted), and the cutting plate (constructed) is engaged with a press plate, which is a cutting plate, following the second cutting, and furthermore, An adjacent fixed support plate is provided integrally with the machine body, and one side E of the support plate and the cutting board is located approximately perpendicular to the center thereof (two guideways are arranged, and the other side C2 is provided with the guideway (two guideways). It is characterized by being provided with a fitting body.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
A device for cutting by extending a predetermined length in the direction of the cutting side of the frame 1 using a push plate 2 such as a feeding cylinder or a speed reducer (a device located above (-) the cutting part of the scrap material of the case frame 1). The press platen 3 of the press cylinder (2) and the cutting plate 4 of the adjacent cutting cylinder (2) have an engaging element 5 which is integrally extended in the extending direction of the case frame 1 (C''-) and engages from above the press plate 3. It is formed into a press plate 3 (two configurations that can be freely engaged and separated).

Further, a fixed support plate 6 adjacent to the cutting board 4 in the extending direction of the case frame 1 is constructed integrally with the machine body, and a guide plate 6 is disposed approximately perpendicular to the center of the cutting board 4. The support plate 6 is provided with two inserts 8 such as rollers or rails into which the guide path 7 is inserted.

In this case, the cutting board 4 is connected to the press board 3 (in the two-engaged state 1
11 (=C2 is set so that the lower surface of the press plate 3 is at a position one step higher than the upper end of the inclined shearing blade 10 of the cutting plate 4, which intersects with the shearing blade 9 of the case frame 1 in a push-cut shape, and the cutting plate 4 is pressed. Cutting (-continue cutting board 4
Press plate 3 engaged with (= leaves room for compression.

Next C: The above embodiment (-Basic effect! If you explain it with two, the press cylinder is started during the cutting operation and the press plate 3 moves downward to the position where it presses and stops the cutting part of the scrap material a. Then, (2) the cutting cylinder is activated and the cutting board 4 is moved down to perform cutting. After the cutting process, the engager 5 of the cutting board 4 is brought into abutment engagement with the press board 3, and the cutting board 4 is pressed. A strong compression force equivalent to the cutting force acts on the press plate 3 (integral C2 transmission) to firmly compress the cutting base of the scrap material a. After the compression, the huffless cylinder is activated and the press is pressed. When the plate 3 is moved upward, the cutting plate 4 along with the press plate 3 automatically moves upward to the initial position by 1" while being engaged by the engaging element 5 and returns to prepare for the next operation. .

When the cutting board 4 reciprocates, the cutting board 4 is guided in vertical vertical movement by the guide path 7 on the vertical line of the cutting board 4 and the insert 8 (:) of the support plate 6 that is fitted into the guide path 7. Furthermore, since the rotational moment acting on the cutting board 4 when cutting scrap material is supported by the guide path 7 and the insert 8C2 fitted therein on the substantially vertical line of the center of the cutting board 4, the rotational moment is sheared. The inclination angle of the cutting board 4 at the time of cutting is made small to ensure cutting.

As is clear from the above explanation C2, the present invention is applicable to the scrap material cutting operation (the press plate 3 presses the cutting base of the scrap material a by pressing the cutting part of the scrap material a), whereas the cutting plate 4 after cutting the scrap material When they abut and engage, a strong compressive force equivalent to the cutting force by the cutting board 4 is applied, resulting in firm compression, so the compression effect is extremely high, the bulk specific gravity increases, and a high quality iron scrap lump is obtained, and the cutting force is reduced. It is also possible to adjust the compression force within the range 1, and also, the above-mentioned cutting line C = recovery of the press plate 3 by the return movement of the fast-moving press cylinder to the return position after the compression process. (The two cutting machines 4 move back together, so the return process is greatly shortened and the processing capacity is greatly improved.)
: In addition to contributing to the improvement of cutting speed and the saving of cylinder power, the rotational moment that acts during shearing (in contrast to cutting 114) is absorbed by the conventional sleeve and the side surface of the cutting board because it is supported on a vertical line approximately at the center of the cutting board. Compared to the sliding friction method, the inclination angle of the cutting board is smaller, so the yarning angle is constant and the cutting can be done reliably.It is also highly durable and robust. 1 It saves the labor of maintenance parts, and reduces the cost of cutting scrap materials. This is an excellent device that increases the economic value of processed and cut scrap materials.
