[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this embodiment discloses a hardware hinge stamping device, including a worktable 1, a lower die 2, an upper die 3, a first push plate 4, and a hydraulic cylinder 5. The worktable 1 includes a first support frame 11, and the hydraulic cylinder 5 is fixed on the upper part of the first support frame 11. The first push plate 4 includes a second support frame 41, and the upper part of the second support frame 41 is fixedly connected to the telescopic rod of the hydraulic cylinder 5. The lower die 2 is fixed on the upper part of the worktable 1, and the upper die 3 is located above the lower die 2. The upper part of the upper die 3 is connected to the first push plate 4 through a connector 100. This connection method is existing technology. Specifically, there are four connectors 100. Each connector 100 includes a connecting rod and a spring sleeved on the outside of the connecting rod. The connecting rod passes through the upper part of the first push plate 4 and the diameter of the protruding end is larger than the diameter of the main body of the connecting rod. The upper part of the first push plate 4 is connected to the end of the telescopic rod of the hydraulic cylinder 5.

[0023] During the stamping operation, the iron belt 9 is located between the lower die 2 and the upper die 3. The hydraulic cylinder 5 drives the first push plate 4 and the upper die 3 to descend. When the upper die 3 abuts against the upper surface of the iron belt 9, the hydraulic cylinder 5 will continue to push the first push plate 4 to descend, thereby compressing the spring and improving the reliability of stamping.

[0024] like Figure 4 and Figure 5As shown, the upper mold 3 includes a first stamping head 31, a second stamping head 32 and a third stamping head 33 in sequence along its length direction. The first stamping head 31 stamps at the first stamping area 91 to punch holes on the surface of the iron belt 9. The second stamping head 32 stamps at the second stamping area 92 to form a hinge piece 94. The third stamping head 33 stamps at the third stamping area 93 to form a hinge piece 95.

[0025] By setting a first stamping head 31, a second stamping head 32, and a third stamping head 33 at the lower part of the upper die 3, hinge piece 1 94 and hinge piece 2 95 can be stamped on the same stamping equipment, which is efficient and produces less stamping waste. Furthermore, a stamping gap is formed between the second stamping head 32 and the third stamping head 33. The size of this stamping gap is the combined size of the second stamping area 92 and the third stamping area 93. By forming a stamping gap, the first hinge piece 94 and the second hinge piece 95 can be stamped at intervals, avoiding the stamping heads from being too close to each other and affecting the stamping quality.

[0026] like Figure 4 As shown, the lower die 2 includes a guide groove 21, a first clearance opening 22, a second clearance opening 23, and a third clearance opening 24 located within the guide groove 21. The guide groove 21 connects both ends of the lower die 2. The first clearance opening 22 is adapted to the first punch head 31, the second clearance opening 23 is adapted to the second punch head 32, and the third clearance opening 24 is adapted to the third punch head 33. During punching, the iron belt 9 passes through both ends of the guide groove 21. The guide groove 21 can limit the iron belt 9 to prevent it from shifting. The first punch head 31 passes through the iron belt 9 and is inserted into the first clearance opening 22 to punch the hinge hole. The second punch head 32 passes through the iron belt 9 and is inserted into the second clearance opening 23 to punch the hinge piece 94. The third punch head 33 passes through the iron belt 9 and is inserted into the third clearance opening 24 to punch the hinge piece 95.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, the lower mold 2 also includes a first discharge groove 25 and a second discharge groove 26 located inside. The upper end of the first discharge groove 25 is connected to a second clearance opening 23, and the upper end of the second discharge groove 26 is connected to a third clearance opening 24. Specifically, the worktable 1 includes a first discharge groove 12 corresponding to the first discharge groove 25 and the second discharge groove 26. A second cylinder 8 corresponding to the first discharge groove 25 and the second discharge groove 26 is fixed on the upper part of the worktable 1. A third push plate 81 is fixed to the end of the telescopic rod of the second cylinder 8. The two first discharge grooves 12 are respectively located at one end opening of the first discharge groove 25 and the second discharge groove 26. The two third push plates 81 are respectively located inside the first discharge groove 25 and the second discharge groove 26. The second cylinder 8 is located at the lower... On the front of mold 2, the first discharge slot 12 is located on the back of the lower mold 2. During the stamping operation, the first hinge piece 94, which is stamped out, will fall from the second clearance slot 23 into the first discharge slot 25, and the second hinge piece 95 will fall from the third clearance slot 24 into the second discharge slot 26. At this time, both second cylinders 8 are working, driving their corresponding third push plates 81 to move. The third push plate 81 located in the first discharge slot 25 will push the first hinge piece 94 from the first discharge slot 25 to the corresponding first discharge slot 12 for discharge; the third push plate 81 located in the second discharge slot 26 will push the second hinge piece 95 from the second discharge slot 26 to the corresponding first discharge slot 12 for discharge. Through the operation of the second cylinders 8, the automatic discharge of the first hinge piece 94 and the second hinge piece 95 can be realized.

[0028] Furthermore, a first cylinder 7 is fixed to the upper part of the upper mold 3, and a second push plate 6 is fixed to the end of the telescopic rod of the first cylinder 7. The second push plate 6 includes a plurality of ejector pins 61, which penetrate the upper mold 3. The ejector pins 61 are respectively located in the second stamping head 32 and the third stamping head 33. Through the first cylinder 7, the ejector pins 61 can be driven to move up and down, thereby pushing the corresponding hinge piece 1 94 and hinge piece 2 95 during stamping, ensuring that the hinge piece 1 94 and hinge piece 2 95 separate from the upper mold 3 and fall down.

[0029] The first push plate 4 also includes a fourth clearance opening 42, which is located above the second push plate 6 and has a larger outer contour dimension than the second push plate 6. The fourth clearance opening 42 is used to avoid the second push plate 6 and prevent the first push plate 4 from contacting the second push plate 6.

[0030] like Figure 3As shown, the lower mold 2 also includes a third discharge groove 27, which is located below the first clearance opening 22. The worktable 1 includes a second discharge groove 13, which is connected to the third discharge groove 27. The second discharge groove 13 is inclined downward. When punching the hinge hole, the waste material after punching will fall from the third clearance opening 24 into the third discharge groove 27 and finally exit from the second discharge groove 13. During punching, even if the waste material blocks the third clearance opening 24, after multiple punchings, the waste material at the back will push the waste material in front to fall down until it falls into the third discharge groove 27.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
