[0020] Example
[0021] Please refer to Figure 1-Figure 3 The present invention proposes a punching die for drawer 100, comprising an upper die 3, a lower die 1 and a middle die 2. The lower die 1 is provided with a slot 11 for placing the drawer 100. The middle die 2 is fixed on the lower die 1 and forms a clamping cavity 200 with an opening at the slot 11. The upper die 3 is slidably mounted on the lower die 1. A plurality of punches 31 are mounted on the side of the upper die 3 facing the lower die 1. During operation, the upper die 3 can approach the lower die 1. At this time, the upper die 3 will drive the punches 31 to punch the drawer 100 in the clamping cavity 200. In this application, the drawer 100 is inverted and inserted into the clamping cavity 200. When punching, the edge material The drawer 100 is pulled out of the drawer 100, and the drawer 100 can take out all the edge materials in the clamping cavity 200, reducing the maintenance work and improving efficiency. The lower mold 1 is equipped with resilient clamping arms 4 on both sides. The space on the left and right sides of the clamping cavity 200 is larger than the left and right lengths of the drawer 100. When the drawer 100 is inserted into the clamping cavity 200, the clamping arms 4 will move away from the lower mold 1, and the ends of the clamping arms 4 will contact the drawer 100. The clamping arms 4 on both sides of the lower mold 1 will clamp the drawer 100. At this time, the drawer 100 can stably perform punching work in the clamping cavity 200.
[0022] In a specific embodiment, reference Figure 1 , holes 12 connecting to the slot 11 are provided on both sides of the lower mold 1, and a frame 5 is installed on both sides of the lower mold 1. The clamping arm 4 is slidably installed in the frame 5 and extends into the slot 11 through the hole 12. A first elastic member 51 that can push the clamping arm 4 to move toward the hole 12 is installed in the frame 5; when the drawer 100 is inserted into the clamping cavity 200, the drawer 100 will squeeze the clamping arm 4 to move outward from the lower mold 1, and the clamping arm 4 will squeeze the first elastic member 51. The first elastic member 51 will exert a squeezing effect on the clamping arm 4, which can stabilize the drawer 100.
[0023] In a specific embodiment, reference Figure 1 、 Figure 3A limiting member 41 is installed on the periphery of the clamping arm 4, and the first elastic member 51 respectively contacts the limiting member 41 and the frame 5. The area of the limiting member 41 is larger than the area of the hole 12 and is located on the outside of the lower mold 1. The running distance of the clamping arm 4 is limited by setting the limiting member 41 on the clamping arm 4. The limiting member 41 can limit the clamping arm 4 from extending too long into the lower mold 1, usually 0.5cm-1cm, which can facilitate the drawer 100 to squeeze the clamping arm 4 and move away from the lower mold 1. The frame 5 is used to provide a contact point for the first elastic member 51.
[0024] In a specific embodiment, reference Figure 3 A roller 42 is installed at one end of the clamping arm 4 facing the slot 11. The rotation axis of the roller 42 is parallel to the sliding path of the upper mold 3 and the lower mold 1. When the drawer 100 is inserted into the clamping cavity 200, the drawer 100 may be worn by contacting the clamping arm 4. By providing the roller 42, the friction between the clamping arm 4 and the drawer 100 can be reduced, thereby improving the yield rate.
[0025] In a specific embodiment, reference Figure 2 The upper mold 3 and the lower mold 1 are connected by a sliding shaft, and a second elastic member is sleeved on the sliding shaft. The two ends of the second elastic member respectively resist the upper mold 3 and the lower mold 1. The elasticity of the second elastic member is sufficient to support the upper mold 3 to separate from the lower mold 1. Therefore, the upper mold 3 can be opened with the lower mold 1 without the action of external force.
[0026] In a specific embodiment, reference Figure 1 The upper die 3 and the lower die 1 are both provided with mounting holes, and the upper die 3 and the lower die 1 can be fixed to the cylinder through the mounting holes.
[0027] In a specific embodiment, reference Figure 1 The thickness of the clip cavity 200 is greater than the thickness of the drawer 100 , the depth of the clip cavity 200 is greater than the depth of the drawer 100 , and the length of the clip cavity 200 is slightly greater than the length of the drawer 100 .
[0028] In a specific embodiment, reference Figure 1 、 Figure 2 R corners 13 are provided on both sides of the entrance of the slot 11. The R corners 13 on both sides of the entrance of the slot 11 can play a certain guiding role when the drawer 100 is inserted into the clip cavity 200, and at the same time make it easier for people to insert the drawer 100 into the clip cavity 200, thereby improving efficiency.
[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
