DETAILED DESCRIPTION

[0021] The following will be described in detail in combination with the accompanying Figures 1-5 The present application will be further described in detail.

[0022] The application embodiment discloses a material leakage prevention structure for a punch press. Figure 1 , Figure 2 , Figure 3The utility model provides a kind of material feeding device for punch press, including tubular blanking pipe 1, and tubular moving pipe 2 is slidably connected on the outer surface of blanking pipe 1, so that when using on different height punch press, the height of moving pipe 2 can be adjusted by sliding moving pipe 2, so that the lower end of moving pipe 2 is flush with the upper edge of receiving box, to reduce the leakage problem of material in the falling process, second, cuboid support plate 3 is fixedly connected on the outer surface of blanking pipe 1, two clamping plates 4 are slidably connected on the upper surface of support plate 3, so that two clamping plates 4 are clamped on the two sides of punch press workbench of different width by the relative sliding of two clamping plates 4, so that the device is stably fixed, improve the practicability and universality of the device, and a plurality of buffer plates 5 are fixedly connected on the inner wall of blanking pipe 1 and moving pipe 2, so that the speed of material falling is reduced by buffer plate 5, so that the speed of material falling into receiving box can be reduced, to avoid the collision of material and receiving box or cause material rebound to cause material to fall to outside, effectively prevent the emergence of material leakage, improve the stability of production line, sponge pad 6 is fixedly connected on the upper surface of a plurality of buffer plates 5, so that the impact of material is buffered by sponge pad 6, to avoid material from being damaged by direct hard contact with buffer plate 5, so as to ensure the blanking quality of punch press.

[0023] Refer to Figure 1 Two cuboid first support blocks 7 and two cuboid second support blocks 9 are fixedly connected on the upper surface of support plate 3, cylindrical guide rail 8 is fixedly connected between the side surface of two first support blocks 7, and the outer surface of guide rail 8 is slidably connected with two clamping plates 4, and double-head screw 10 is rotatably connected between the side surface of two second support blocks 9, and the outer surface of double-head screw 10 is rotatably connected with two clamping plates 4, so that two clamping plates 4 are driven to slide oppositely or away from each other by rotating double-head screw 10 while being limited by guide rail 8, so that the device can be fixed under punch press workbench of different width, improve the flexibility of device.

[0024] Refer to Figure 4 、 Figure 5A plurality of slot-shaped sliding grooves 11 are formed on the outer surface of the blanking pipe 1, a plurality of block-shaped sliding blocks 12 are fixedly connected to the inner wall of the moving pipe 2, and the sliding blocks 12 slide with respect to the inner wall of the sliding grooves 11. In addition, a plurality of slot-shaped clamping grooves 13 are formed on the outer surface of the blanking pipe 1, and a slot-shaped mounting groove 14 is formed on the inner wall of the moving pipe 2. A block-shaped clamping block 15 is elastically and slidably connected to the inner wall of the mounting groove 14 through a spring, and the clamping block 15 can be clamped to the inner wall of any one of the clamping grooves 13. When it is necessary to fix the device to a punch at different heights, the clamping block 15 is pulled away from the current clamping groove 13 by the worker, and then the moving pipe 2 is slid so that the sliding block 12 slides on the inner wall of the sliding groove 11. After sliding to the corresponding position, the clamping block 15 will rebound and be clamped to the inner wall of the corresponding clamping groove 13 under the resetting action of the spring, thereby completing the rapid adjustment of the height of the moving pipe 2. When the device is used at different heights of the punch, the lower end of the moving pipe 2 can be flush with the upper edge of the receiving box, thereby preventing the material from leaking.

[0025] The implementation principle of the material leakage prevention structure for the punch blanking device is as follows: during use, the worker rotates the double-headed screw 10 while limiting the sliding of the clamping plate 4 through the guide rail 8, thereby driving the two clamping plates 4 to slide relative to each other and be clamped to the two sides of the punch workbench with different widths, so that the device is stably fixed. Then, according to the distance between the punch and the receiving box, the moving pipe 2 is moved by a certain distance, the clamping block 15 is pulled away from the current clamping groove 13 by the worker, and then the moving pipe 2 is slid so that the sliding block 12 slides on the inner wall of the sliding groove 11. After sliding to the corresponding position, the clamping block 15 will rebound and be clamped to the inner wall of the corresponding clamping groove 13 under the resetting action of the spring, thereby completing the rapid adjustment of the height of the moving pipe 2. When the device is used at different heights of the punch, the lower end of the moving pipe 2 can be flush with the upper edge of the receiving box, thereby preventing the material from leaking. While blanking, the material will roll down along the upper surface of the buffer plate 5, so as to reduce the speed of the material falling through the buffer plate 5, thereby reducing the speed of the material falling into the receiving box, avoiding the collision between the material and the receiving box or the rebound of the material causing the material to fall outside, effectively preventing the leakage of the material, improving the stability of the production line, and simultaneously buffering and protecting the impact of the material through the sponge pad 6, avoiding the damage of the material directly contacting the buffer plate 5, thereby ensuring the blanking quality of the punch.
