The cutting blade 5 is connected to the push rod motor 4. In the initial state, the cutting blade 5 is positioned above the female die 3. After the steel template to be cut is placed on the female die 3, the push rod motor 4 extends to drive the cutting blade 5 to move downwards, and then the plate cutting of the steel template can be completed.

The support 2 comprises at least four uprights 2 a. The upright post 2a is sleeved with a slide block 6. The slider 6 is connected to the pusher motor 4. The sliding block 6 can be driven to move up and down through the push rod motor 4. The cutting blade is provided on the slider 6. The upright posts 2a are also sleeved with a pressing plate 7, and each upright post 2a is sleeved with a first compression spring 8. The first compression spring 8 is located between the base 1 and the pressure plate 7, and the first compression spring 8 can be compressed when the slider 6 slides in the extending direction of the column 2a to push the pressure plate. When the slide 6 moves downwards, the cutting blade 5 and the slide move downwards and the platen 7 can move downwards to come into abutting contact with the female die 3. For example, as shown in fig. 1, when the slider 6 moves downward, the cutting blade 5 and the slider 6 move downward by a distance such that the slider 6 first comes into contact with the platen 7. As the slide 6 continues to move downwardly, the first compression spring 8 can be compressed so that the platen 7 can move downwardly into abutting contact with the female die 3. Each upright post is also sleeved with a second compression spring 17, and a second compression spring 18 is positioned between the slide block 6 and the pressure plate. The second compression spring can be compressed with the platen 7 in abutting contact with the die 3 and the slide 6 continuing to move down. In the bending process, the pressing plate 7 can compress a steel molding plate placed on the female die 3, and the phenomenon that the shearing precision is reduced due to movement in the shearing process is avoided. The pressing plate 7 is provided with a rubber pad 9. Can avoid clamp plate 7 to cause the damage to the steel form surface through rubber pad 9, can improve the shearing quality of steel sheet.

The female die 3 is provided with a first material bearing surface 10 and a second material bearing surface 11. Under the condition that the first material bearing surface 10 is approximately parallel to the ground, the second material bearing surface 11 has an included angle of less than 90 degrees with the ground. The steel sheet after the plate shearing can slide along the second material bearing surface 11 based on the dead weight of the steel sheet, and then automatic discharging is realized.

The first material bearing surface 10 is provided with a plurality of rotating rollers 12, and the axial direction of the rotating rollers 12 is approximately parallel to the ground. A ratchet mechanism 13 coupled to the rotating roller 12 is provided in the female die 3. The ratchet mechanism 13 includes at least a first ratchet plate 13a, a second ratchet plate 13b, and a pawl 13 c.

The working principle of this application does: in the initial state, the first compression spring 8 and the second compression spring 17 are both in a natural, stretched state. The coil spring 15 is in a compressed state. When the push rod motor 4 extends to drive the slide block 6 to move downwards, the first compression spring 8 and the second compression spring 17 are gradually compressed, so that the press plate 7 and the slide block 6 can move downwards. When the pressing plate 7 moves downward, the elastic potential energy of the coil spring 15 is released, and it can drive the first ratchet disk 13a to rotate, at this time, the claw 13c will not generate pushing force to the second ratchet disk 13 b. After the pressing plate 7 comes into abutting contact with the female die 3, the pressing plate 7 stops moving, and at this time, the second compression spring 17 continues to be compressed, so that the cutting blade 5 moves downward to cut the steel form. Finally, the push rod motor 4 is shortened to drive the slide block 6 to move upwards, at this time, the slide block 6 will pull the first ratchet wheel disc 13a to rotate through the second connecting belt 19, at this time, the claw 13c will be matched with the first ratchet wheel disc 13a, so that the second ratchet wheel disc 13b rotates, and then the rotating roller 12 is driven to rotate. As shown in fig. 2, the rotary roller 12 rotates to move the uncut material and the cut material to the right, thereby completing the feeding and discharging.
