the roller 49 is made of polyurethane.
The principle of the invention is illustrated as follows:
as shown in fig. 1, a coil enters from the feeding side of the die and moves on the lower die base 2, the coil sequentially passes through the feeding roller strip group 9, the rotary material supporting device 8, the lower die cutter block 3, the elastic material supporting frame 4 and the discharging roller strip group 5, at this time, the material supporting arm 82 is in a lifting state, the material supporting frame spring 41 at the bottom of the elastic material supporting frame 4 is stretched, and the elastic material supporting frame 4 supports the coil, so that the coil is prevented from being scratched by the cutting edge of the lower die cutter block 3; meanwhile, the rolling body 42 is arranged at the top of the elastic material supporting frame 4, friction force between the rolling body 42 and the coiled material is small, and the coiled material is prevented from being scratched.
The top of the elastic material supporting frame 4 can also be arranged into other structures with small friction force with the coil materials; and rollers are arranged at the tops of the single feeding roller strip and the single discharging roller strip, so that coiled materials or cut plates can be conveyed conveniently.
As shown in fig. 2, when the shearing die shears the coil stock, the coil stock stops moving, the upper die holder 1 and the lower die holder 2 are closed, the die is closed, the pressing block 84, the elastic material pressing device 6 and the upper die cutter block 7 press down along with the upper die holder 1, at this time, a boss correspondingly arranged on the upper die holder 1 presses a cushion block 44 at the top of the roller seat 43, the material supporting frame spring 41 is compressed downwards, at this time, the pressing block 84 presses the material supporting arm 82 downwards and presses the material supporting arm 82 to a horizontal state, and the material pressing device spring 61 is compressed, so that the coil stock is kept flat in the cutting process; meanwhile, as the horizontal distance between the end surface of the upper die cutter block 7 close to the feeding side and the end surface of the lower die cutter block 3 close to the discharging side is less than 0.04mm, the upper die cutter block 7 is matched with the cutting edge of the lower die cutter block 3 after falling down to cut off the coil stock, and a plate is formed.
Subsequently, as shown in fig. 3, the upper die holder 1 and the lower die holder 2 are separated, the coil stock continues to move from the feeding side to the discharging side of the die, the pressing block 84, the elastic material pressing device 6 and the upper die cutter block 7 rise along with the upper die holder 1, at this time, the material supporting arm 82 rotates upwards under the action of the return spring 83 to lift the coil stock close to the cutting opening, the cutting opening of the coil stock is prevented from cutting the roller shaft 47 or the roller 49 on the elastic material supporting frame 4 when the coil stock moves to the discharging side of the die, and meanwhile, the lower die cutter block 3 is prevented from scraping the coil stock. The rotary material supporting device 8 is arranged close to the lower die cutter block 3, so that the material supporting arm 82 can lift the coiled material close to the cut.
Meanwhile, after the coil stock is cut into the sheet stock, the material supporting frame spring 41 resets, and the rolling body 42 at the top of the elastic material supporting frame 4 supports one end of the sheet stock close to the lower die cutter block 3, so that the sheet stock slides to the discharging roller strip group 5 and then slides down to the discharging belt conveyor 10 from the inclined discharging roller strip group 5.
The roller seat 43 is provided with a guide screw 45, when the cushion block 44 on the roller seat 43 is extruded and the material supporting frame spring 41 is compressed, the roller seat 43 slides up and down along the vertical direction on the lower die base 2 along the direction of the guide screw 45, so that the deviation of the roller seat 43 is avoided. The middle section of the screw rod of the guide screw 45 can be provided with no thread, so that the roller seat 43 can slide up and down along the screw rod conveniently. Meanwhile, the upper end of the guide screw 45 is in limit fit with the roller seat 43, so that the roller seat 43 can be prevented from being separated from the guide screw 45.
The guide post 23 is used for ensuring that the gap between the upper die cutter block 7 and the lower die cutter block 3 is proper, and when a coil stock with the thickness of 0.8MM is actually sheared, the lower surface of the upper die cutter block 7 is about 1MM below the top surface of the lower die cutter block 3 after the upper die cutter block 7 moves downwards to the lowest position.
