[0002] Stamping dies are tools used in stamping processes, primarily for processing sheet metal. They enable a series of operations such as cutting and punching holes in sheet metal. In the processing of some pipe fittings, which have a curved central section and through holes at both ends, the corresponding stamping dies are mostly single-operation dies. These dies require manual loading, unloading, and waste collection, and cannot perform integrated punching and cutting operations, thus their processing efficiency needs improvement. Utility Model Content

[0003] The purpose of this invention is to provide a metal stamping die to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal part stamping die, comprising:

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a metal stamping die, comprising: a lower template 2, with a limiting part installed on the top of the lower template 2, the limiting part including an upper limiting plate 8 and a lower limiting plate 9 arranged vertically, the ends of the lower limiting plate 9 and the upper limiting plate 8 each having a limiting groove 11, the upper and lower limiting grooves 11 forming a cutting groove; an upper template 1 placed above the lower template 2, the bottom of the lower template 2 being fixedly connected to a punch 5 that cooperates with the limiting part; a forming separation part placed above the lower template 2, the separation part including an upper forming pressure block 6 fixedly connected below the upper template 1, a lower forming pressure block 17 fixedly connected to the top of the lower template 2, and a dual-axis cylinder 12 for driving the material feeding, one end of the upper forming pressure block 6 corresponding to the cutting groove, when the upper forming pressure block 6 moves downward, it first cuts the metal sheet at the end of the lower limiting plate 9 and then cooperates with the upper forming pressure block 6 to extrude and form.

[0024] It should be noted that in this embodiment, the upper template 1 is connected to the lifting mechanism of the stamping equipment, and the lower template 2 is installed above the processing table. The aluminum plate is conveyed forward by the conveying equipment. The aluminum plate is conveyed intermittently between the upper limit plate 8 and the lower limit plate 9. After being conveyed to a specified length, the controller sends a signal to the lower limit plate 9, and the controller controls the stamping equipment to move the upper template 1 downward. In this way, the punch 5 penetrates the upper limit plate 8 and the lower limit plate 9, thereby punching a hole in the aluminum plate between the upper limit plate 8 and the lower limit plate 9. After the upper template 1 is reset upward, the conveying equipment conveys the aluminum plate forward again. After being conveyed to a specified length, the open section is located at the top of the upper forming block 6, and the top of the upper forming block 6 is at the same height as the lower limit plate 9. Before punching the aluminum plate downwards, one end of the upper forming block 6 engages with the cutting groove and moves downwards inside the cutting groove to cut the aluminum plate extending from the upper limit plate 8 and the lower limit plate 9. The cut aluminum plate is then squeezed between the upper forming block 6 and the forming groove 7 to extrude and form the aluminum plate. When the upper template 1 resets upwards and engages with the corresponding limit switch, the controller controls the dual-axis cylinder 12 to push the forming material on the top of the lower forming block 17 forward. This cycle is repeated to complete the continuous processing.

[0025] In one embodiment, the upper limit plate 8, the lower limit plate 9, and the lower template 2 are all provided with through holes at the positions corresponding to the punch 5. I-beams 18 are fixedly connected to both sides of the bottom of the lower template 2, and a conveyor 14 is fixedly connected between the two I-beams 18.

[0026] It should be noted that in this embodiment, the second through hole is located above the conveyor 14. The conveyor 14 is a belt conveyor. After the punch 5 penetrates the aluminum plate, the waste material under its punching falls onto the conveyor 14 along the second through hole. The conveyor 14 transports it forward from one end, so that the material falls into the corresponding collection box.

[0027] In one embodiment, a connecting plate 3 is fixedly connected to the bottom of the upper template 1, and the upper forming block 6 is fixedly connected to the connecting plate 3. Multiple guide rods 4 are provided at the bottom of the connecting plate 3, and the upper limit plate 8 and the lower limit plate 9 are both provided with through holes that cooperate with the guide rods 4.

[0028] It should be noted that in this embodiment, the upper template 1 is connected to the lifting mechanism. The lifting mechanism drives the upper template 1 and the connecting plate 3 to rise and fall. The guide rod 4 slides up and down in the through hole of the upper limit plate 8 and the lower limit plate 9. In this way, the rising and falling of the connecting plate 3 can be guided by the guide rod 4, thereby ensuring the accuracy of the impact position of the punch 5.

[0029] In one embodiment, two limiting strips 10 are fixedly connected between the upper limiting plate 8 and the lower limiting plate 9 at the position corresponding to the limiting groove 11, and the two limiting strips 10 form a conveying channel 19.

[0030] It should be noted that in this embodiment, the two conveying channels 19 are located between the upper limit plate 8 and the lower limit plate 9, and the two limiting strips 10 are respectively located at the ends of the limiting grooves 11. The width of the two limiting strips 10 is adapted to the width of the aluminum strip, thereby forming the conveying channels 19. The aluminum plate is limited by the conveying channels 19, so that it can be conveyed forward stably.

[0031] In one embodiment, the bottom of the upper forming block 6 is provided with a forming groove 7, and the top of the lower forming block 17 is provided with a protrusion that cooperates with the forming groove 7.

[0032] It should be noted that, in this embodiment, when the upper forming block 6 moves downward, one end of the upper forming block 6 moves along the cutting groove formed by the limiting groove 11, and the bottom of one end of the upper forming block 6 moves from top to bottom along the cutting groove.

[0033] The movement cuts the aluminum plate located between the upper limit plate 8 and the lower limit plate 9 by extrusion, thereby separating the aluminum plate after the opening. Through the cooperation of the upper forming pressure block 6 and the forming groove 7, the cut aluminum plate is pressed into a connector with an arc-shaped structure in the middle.

[0034] In one embodiment, a baffle 13 is fixedly connected to one end of the lower template 2 and the position corresponding to the dual-axis cylinder 12. The dual-axis cylinder 12 is fixedly connected to the top of the lower template 2. Two push rods 16 are fixedly connected to the output end of the dual-axis cylinder 12 above the lower forming block 17. A receiving groove 15 is fixedly connected to one end of the lower template 2 away from the dual-axis cylinder 12.

[0035] It should be noted that in this embodiment, when the punching position of the aluminum plate corresponds to the punch 5, its end contacts the baffle 13. When the upper template 1 is reset upward, under the action of the limit switch, the controller controls the dual-axis cylinder 12 to drive the push rod 16 forward. The push rod 16 slides on the top of the lower forming block 17, thereby pushing the workpiece on the top of the lower forming block 17 into the receiving groove 15 and sliding it downward into the receiving box.
