Description

Technical Field

[0001] The present disclosure relates to the field of stamping equipment, and in particular to a terminal stamping device and stamping equipment. Background Art

[0002] Terminal blocks are an accessory product that enables electrical connections and are a type of connector, widely used in electronic, electrical, and communications equipment. During the terminal stamping process, the material strip is punched to form the corresponding terminal shape. During the stamping process, the excess structure of the strip is cut off by the punch, forming waste. This waste needs to be cleaned to prevent it from remaining in the stamping equipment and affecting the terminal forming accuracy.

[0003] The Chinese patent application number CN202010541813.7 discloses a relay terminal stamping machine, including a workbench and a stamping table located on one side of the workbench, the top of the workbench is rotatably connected to a fixed rod, and a horizontally arranged horizontal plate is fixed at the top edge of the fixed rod. A waste collection box is provided on one side of the workbench, and an electromagnet located on one side of the workbench is fixed at one end of the bottom of the horizontal plate. An arc-shaped insulating plate is fixed on the top of the workbench, and a negative terminal plate and a positive terminal plate are embedded on the outer arc wall and the inner arc wall of the insulating plate respectively. The bottom of the horizontal plate is fixed with a negative terminal post that is slidably connected to the negative terminal plate through a connecting plate.

[0004] The aforementioned terminal stamping machine utilizes an electromagnet and a waste collection box installed on one side of the workbench. The electromagnet attracts the waste on the stamping table, automatically dropping it into the waste collection box. However, waste that is far from the electromagnet experiences less attraction and is difficult to drop into the waste collection box. This results in poor waste cleaning and necessitates subsequent cleaning, resulting in lower production efficiency. Furthermore, the need to install the electromagnet and waste collection box on the workbench complicates the overall structure of the stamping machine.

[0005] Therefore, there is an urgent need for a stamping device with a simple structure, good waste cleaning effect and the ability to improve production efficiency. Utility Model Content

[0030] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0031] like Figure 1 and Figure 2As shown, a terminal stamping device 10 of an embodiment includes an upper die 100, an upper punch 200, a lower die 300, a lower punch 400, an extrusion plate 500 and an elastic member 600, wherein the upper punch 200 is installed on the upper die 100, and the lower punch 400 is installed on the lower die 300, and the upper punch 200 and the lower punch 400 cut off the product and the waste when they move toward each other, the extrusion plate 500 is located between the upper die 100 and the lower die 300, the lower die 300 is provided with a mounting hole 310, and the elastic member 600 is located in the mounting hole 310, and the two ends of the elastic member 600 are respectively connected to the extrusion plate 500 and the lower die 300, and the extrusion plate 500 is provided with an extrusion groove 511, and the extrusion groove 511 is arranged corresponding to the lower punch 400, and the extrusion plate 500 is used to wrap the cut waste on the surface of the product during elastic reset.

[0032] In this embodiment, the semi-finished terminal is first placed on the lower punch 400. The semi-finished terminal is pre-stamped into a corresponding shape, but the waste and the terminal are not completely broken. In this process, the terminal and the waste need to be cut off. Specifically, the semi-finished terminal is located at the lower punch 400. When the upper punch 200 and the lower punch 400 move toward each other, the upper punch 200 passes through the extrusion groove 511 and cuts off the waste and the terminal, and the extrusion plate 500 is squeezed by the upper mold 100, so that the elastic member 600 is compressed. At this time, the broken waste adheres to the groove wall of the extrusion groove 511. When the upper mold 100 and the lower mold 300 are separated, the elastic member 600 stretches, so that the extrusion plate 500 is reset. The waste is squeezed by the groove wall of the extrusion groove 511 and attached to the surface of the terminal, that is, the waste is shaped on the surface of the terminal by the extrusion plate 500. Finally, the waste and the terminal are clamped away from the workstation by the robot. During the clamping process, the robot shakes to separate the waste and the terminal.

[0033] In the above-mentioned terminal stamping device 10, the lower die 300 is provided with a mounting hole 310, the elastic member 600 is located in the mounting hole 310, the two ends of the elastic member 600 are respectively connected to the extrusion plate 500 and the lower die 300, the extrusion plate 500 is located between the upper die 100 and the lower die 300, and the extrusion plate 500 is provided with an extrusion groove 511, and the extrusion groove 511 is arranged corresponding to the lower punch 400. Specifically, when the upper punch 200 and the lower punch 400 move toward each other, the upper punch 200 will cut off the products and waste that are not completely broken, and the waste will adhere to the groove wall of the extrusion groove 511. At this time, the elastic member 600 is in a compressed state. After the upper die 100 and the lower die 300 are separated, the elastic member 600 stretches, so that the extrusion plate 500 is reset to press the waste in the extrusion groove 511 and wrap it on the surface of the product. Finally, the waste and the terminal are clamped away from the workstation by the robot. During the clamping process, the robot shakes to separate the waste from the terminal, that is, the waste and the product are formed into a whole in each stamping process, and finally at the clamping workstation, the waste cleaning effect is better, the subsequent cleaning work of the workstation is reduced, and the production efficiency is improved. This can be achieved by adding the extrusion plate 500 and the elastic member 600, and the overall structure of the device is simpler and more compact.

[0034] like Figure 2 As shown, in one embodiment, the extrusion plate 500 includes a plate body 510 and a connecting post 520. The plate body 510 is fixedly connected to the connecting post 520. The extrusion groove 511 is opened in the plate body 510. Part of the structure of the connecting post 520 is located in the mounting hole 310 and is connected to the elastic member 600. In this embodiment, the plate body 510 is located between the upper mold 100 and the lower mold 300. The plate body 510 is connected to the top of the connecting post 520, and the bottom of the connecting post 520 is connected to the elastic member 600. When the plate body 510 is extruded by the upper mold 100, the elastic member 600 is compressed by the connecting post 520. When the stamping is completed, the upper mold 100 and the lower mold 300 are separated. At this time, the elastic member 600 relaxes, and the plate body 510 is pushed upward by the connecting post 520 to press the waste material in the extrusion groove 511 onto the terminal surface.

[0035] In one embodiment, the plate body 510 and the connecting pillar 520 are integrally formed. In this embodiment, the plate body 510 and the connecting pillar 520 are integrally formed to improve the structural strength of the plate body 510 and the connecting pillar 520.

[0036] like Figure 2As shown, in one embodiment, the number of the mounting holes 310, the connecting posts 520, and the elastic members are all multiple, and the multiple mounting holes 310 are spaced apart in the lower mold 300, and each mounting hole 310 is provided with an elastic member 600 and a connecting post 520. It can be understood that the mounting holes 310 are spaced apart in the lower mold 300, and each mounting hole 310 is provided with an elastic member 600 and a connecting post 520, so that the thrust on the plate 510 is more uniform, and the effect of pressing the waste is better.

[0037] In one embodiment, the elastic member 600 is a spring, so that when the spring is stretched, it drives the extrusion plate 500 to move, thereby pressing the waste material onto the terminal surface.

[0038] like Figure 1 and Figure 2 As shown, in one embodiment, a guide post 310 is protruding from a side surface of the upper mold 100 adjacent to the lower mold 300, and a guide hole 512 is formed in the plate 510. The guide post 310 is arranged corresponding to the guide hole 512. When the upper mold 100 abuts the plate 510, the guide post 310 passes through the guide hole 512. It can be understood that when the upper mold 100 abuts the plate 510, the guide post 310 passes through the guide hole 512 to improve the accuracy of terminal stamping.

[0039] like Figure 1 and Figure 2 As shown, in one embodiment, there are two guide posts 310, which are located on both sides of the upper punch 200. It can be understood that there are also two guide holes 512, which are arranged in a one-to-one correspondence with the guide posts 310 to further improve the accuracy of terminal stamping.

[0040] In one embodiment, the two ends of the elastic member 600 are respectively welded to the lower mold 300 and the extrusion plate 500. It is understandable that the two ends of the elastic member 600 are respectively welded to the lower mold 300 and the extrusion plate 500 to make the connection between the elastic member 600, the lower mold 300 and the extrusion plate 500 more stable.

[0041] In one embodiment, the notch diameter of the extrusion groove 511 is greater than or equal to the diameter of the lower punch 400. In this embodiment, the notch diameter of the extrusion groove 511 is equal to the diameter of the lower punch 400, so that the upper punch 200 can pass through the extrusion groove 511 and cut off the terminal of the lower punch 400 from the waste material, while making the notch of the extrusion groove 511 more closely fit with the lower punch 400, so as to prevent the waste material from falling through the gap between the notch of the extrusion groove 511 and the lower punch 400.

[0042] The present application also provides a stamping device, comprising the terminal stamping device 10 described in any one of the above embodiments.

[0043] Compared with the prior art, the present disclosure has at least the following advantages:

[0044] In the above-mentioned terminal stamping device 10, the lower die 300 is provided with a mounting hole 310, the elastic member 600 is located in the mounting hole 310, the two ends of the elastic member 600 are respectively connected to the extrusion plate 500 and the lower die 300, the extrusion plate 500 is located between the upper die 100 and the lower die 300, and the extrusion plate 500 is provided with an extrusion groove 511, and the extrusion groove 511 is arranged corresponding to the lower punch 400. Specifically, when the upper punch 200 and the lower punch 400 move toward each other, the upper punch 200 will cut off the products and waste that are not completely broken, and the waste will adhere to the groove wall of the extrusion groove 511. At this time, the elastic member 600 is in a compressed state. After the upper die 100 and the lower die 300 are separated, the elastic member 600 stretches, so that the extrusion plate 500 is reset to press the waste in the extrusion groove 511 and wrap it on the surface of the product. Finally, the waste and the terminal are clamped away from the workstation by the robot. During the clamping process, the robot shakes to separate the waste from the terminal, that is, the waste and the product are formed into a whole in each stamping process, and finally at the clamping workstation, the waste cleaning effect is better, the subsequent cleaning work of the workstation is reduced, and the production efficiency is improved. This can be achieved by adding the extrusion plate 500 and the elastic member 600, and the overall structure of the device is simpler and more compact.

[0045] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the present patent shall be determined by the appended claims.
