[0003] When stamping is carried out currently, the fixing effect on the sheet is relatively single, and it can only directly stamp after pressing the sheet, and it is impossible to ensure that after the sheet is pressed and fixed, the die can continue to move downward to perform the next stamping operation, so as to ensure the accuracy effect of stamping. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that the fixing effect on the sheet is relatively single, and it can only directly stamp after pressing the sheet, and it is impossible to ensure that after the sheet is pressed and fixed, the die can continue to move downward to perform the next stamping operation, so as to ensure the accuracy effect of stamping, and a continuous automatic hardware stamping die is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A continuous automatic hardware stamping die includes a machine body, and a coil feeder is arranged on one side of the machine body;

[0007] An upper die holder and a lower die holder for installing the die, the lower die holder is fixedly arranged on the inner bottom wall of the machine body, the upper die holder is located above the lower die holder, an upper template is fixedly arranged at the bottom of the upper die holder, and a lower template is fixedly arranged at the top of the lower die holder;

[0008] A fixing frame for fixing the sheet, the fixing frame is slidably sleeved on the outer wall of the upper template, two first bottom plates are fixedly arranged on the top of the lower die holder, and the two first bottom plates are respectively located on both sides of the lower template, two second bottom plates are fixedly arranged on the top of the lower die holder, and the two second bottom plates are respectively located on the other two sides of the lower template, and the first bottom plates and the second bottom plates are all matched with the fixing frame;

[0009] A locking component for connecting the upper template and the fixing frame, and the locking component is arranged inside the fixing frame.

[0010] In a possible design, a cylinder is fixedly arranged on the inner top wall of the machine body, and the upper die holder is fixedly arranged with the output shaft of the cylinder.

[0011] In a possible design, two limiting rods are fixedly arranged on both sides of the bottom of the upper die holder. The fixed frame is slidably sleeved on the outer walls of the plurality of limiting rods. A first compression spring is sleeved on the outer wall of the limiting rod, and both ends of the first compression spring are fixedly arranged on the bottom of the upper die holder and the top of the fixed frame respectively. Two concave holes are formed in the top of the first bottom plate, and the plurality of concave holes are matched with the plurality of limiting rods.

[0012] In a possible design, the locking assembly includes a plug rod and a resisting rod. One circular groove is formed on each side of the upper template, and the two plug rods are respectively slidably arranged inside the two circular grooves. Second circular grooves are formed on the inner walls of both sides of the fixed frame, and the two resisting rods are respectively slidably arranged inside the two circular grooves. One end of the plug rod slidably extends into the second circular groove, and one end of the plug rod is matched with the resisting rod.

[0013] In a possible design, the locking assembly further includes two vertical plates which are respectively fixedly arranged on the tops of the two second bottom plates.

Detailed Implementation Modes

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Embodiment 1

[0027] Referring to Figure 1 , a continuous automatic hardware stamping die, which is applied in the field of metal processing, includes: a machine body 1, which serves as the support structure of the entire die. A coil feeder 5 is installed on one side of the machine body 1 for automatically conveying the plate to be stamped.

[0028] Next, an upper die holder 3 and a lower die holder 4 are provided. The lower die holder 4 is fixedly installed on the bottom inner wall of the machine body 1, while the upper die holder 3 is located above the lower die holder 4 and moves up and down through the drive of a cylinder 2. The cylinder 2 is fixedly arranged on the top inner wall of the machine body 1, and its output shaft is fixedly connected to the upper die holder 3 to ensure the smoothness and accuracy of the stamping operation.

[0029] Referring to Figure 2 , an upper template 6 is fixedly installed at the bottom of the upper die holder 3, and a lower template 12 is fixedly installed at the top of the lower die holder 4. In order to fix the plate to be stamped, a fixing frame 7 is designed to be slidably sleeved on the outer wall of the upper template 6. The design of the fixing frame 7 enables the plate to remain stable during the stamping process and improves the stamping accuracy. Two first bottom plates 10 and two second bottom plates 15 are also fixedly arranged at the top of the lower die holder 4. They are respectively located on both sides of the lower template 12 and cooperate with the fixing frame 7. The plate is pressed and fixed by the bottom plates and the fixing frame 7.

[0030] In addition, two limiting rods 9 are fixedly arranged on both sides of the bottom of the upper die holder 3. The fixing frame 7 is slidably sleeved on these limiting rods 9, and a first compression spring 8 for resetting is arranged between the fixing frame 7 and the upper die holder 3. When the fixing frame 7 presses and fixes the plate, the compression spring is compressed so that the upper template 6 can continue to perform the stamping operation downward.

[0031] Embodiment 2

[0032] Reference Figures 3 - 4, on the basis of Embodiment 1, the improvement is as follows: In order to achieve the effect that when the fixed frame descends to a specified position where the sheet is fixed, the upper template 6 can continue to move downward for stamping, a locking component is designed. This component includes a plug rod 17 and a resisting rod 20. The plug rod 17 is slidably arranged in the first circular grooves 16 on both sides of the upper template 6, while the resisting rod 20 is slidably arranged in the second circular grooves 21 on the inner walls of both sides of the fixed frame 7. One end of the plug rod 17 extends into the second circular groove 21 and cooperates with the resisting rod 20 to achieve the locking function. A second compression spring 18 is also arranged in the first circular groove 16, and its two ends are respectively fixed on one inner wall of the first circular groove 16 and one end of the plug rod 17 to ensure that the plug rod 17 can remain stable in the locked state.

[0033] Regarding unlocking, vertical plates 14 are arranged on the tops of both second bottom plates 15 and cooperate with the side grooves 19 at the bottom of the fixed frame 7. An inclined groove 22 is formed on one side of the outer wall of the resisting rod 20 close to the side groove 19, and an inclined strip 13 is fixedly arranged on one side of the vertical plate 14. The inclined strip 13 cooperates with the inclined groove 22. When the fixed frame 7 moves downward to a specific position, the inclined strip 13 will push the inclined groove 22, thereby driving the resisting rod 20 to move. The resisting rod 20 will push the plug rod 17 out of the inside of the second circular groove 21, thus unlocking.

[0034] Specifically, when the upper die holder 3 drives the upper template 6 to move downward, the upper template 6 will drive the fixed frame 7 to move downward together. The sheet is pressed by the fitting of the fixed frame 7 with the first bottom plate 10 and the second bottom plate 15. And when the fixed frame 7 moves downward, the lower vertical plate 14 will be inserted into the inside of the side groove 19, and then the inclined strip 13 will be inserted into the inside of the inclined groove 22. When the fixed frame 7 continues to move downward, the resisting rod 20 will be displaced under the influence of the inclined strip 13, causing it to push against the plug rod 17 to move and push the plug rod 17 into the inside of the first circular groove 16. When the fixed frame 7 fits with the second bottom plate 15 and the first bottom plate 10, the plug rod 17 and the resisting rod 20 will be respectively located inside the first circular groove 16 and the second circular groove 21, releasing the connection between the upper template 6 and the fixed frame 7 so that the upper template 6 can continue to move downward for stamping to ensure that stamping operations can only be carried out after it is fixed.
