Technical Field

[0001] This utility model relates to the field of terminal block stamping, and in particular to a stamping die for terminal blocks. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. They are a type of connector. When manufacturing terminal blocks using existing technology, it is usually necessary to punch copper, aluminum, copper alloys, or copper-aluminum alloys into conductive sheets of the required shape and size. It is also necessary to punch the connection position with the wire into a ring shape to facilitate the connection between the terminal block and the wire.

[0003] In the existing technology, during the stamping process of terminal blocks, the stamping die is usually driven by a hydraulic cylinder to stamp the parts of the stamping platform. Traditional stamping dies are difficult to adapt to the stamping requirements of different specifications of terminal blocks. When stamping different specifications of terminal blocks, the stamping die needs to be changed frequently, which greatly reduces the stamping efficiency of terminal blocks and is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a stamping die for terminal blocks with an ingenious structure that enables quick installation and disassembly of the stamping blocks while ensuring their stability during the stamping process. It is convenient and practical.

The output end of the stamping cylinder is provided with a stamping assembly. The stamping assembly includes a first connecting body connected to the output end of the stamping cylinder, a second connecting body coaxially arranged and rotatably disposed within the first connecting body, a third connecting body that can be installed within the second connecting body, a stamping block installed at the bottom of the third connecting body, and a cutting blade. The first connecting body is provided with a stamping block coaxially arranged with the first connecting body. The first mounting groove is provided on the shaft, and a positioning shaft and a square positioning plate detachably mounted on the bottom of the positioning shaft by a locking device are provided in the first mounting groove. The second connecting body is provided with a second mounting groove coaxial with the second mounting body, and a rotating cylinder coaxial with the second mounting groove is provided in the second mounting groove. The rotating cylinder is provided with a connecting through hole through which the positioning shaft can pass. A torsion spring is sleeved on the positioning shaft, and the two ends of the torsion spring are fixedly connected to the inner wall of the connecting through hole and the positioning shaft, respectively. The outer wall of the second connecting body is provided with a receiving device coaxial with the second connecting body. The cable groove has a pull rope wound inside it. A rope outlet hole is provided on the side wall of the first connector. One end of the pull rope is fixed inside the take-up groove, and the other end of the pull rope extends out of the first connector through the rope outlet hole after being wound multiple times around the take-up groove. A pull block is provided on the end of the pull rope extending out of the first connector to prevent it from retracting back into the cable groove. Multiple connecting blocks are circumferentially distributed along the axis of the second mounting groove on its inner wall. The third connector is coaxially mounted in the second mounting groove. The third connector has connecting grooves corresponding to each connecting block, and each connecting groove includes a groove parallel to the axis of the third connector. The second connector has an axial slot and a circumferential slot coaxial with the axis of the third connector. The axial slot and the circumferential slot are connected. The third connector has an intermediate slot for inserting a rotating cylinder. The bottom of the third connector also has a positioning slot corresponding to the positioning plate. The third connector passes through the axial slot and the circumferential slot in sequence and then engages with the second connector. It is fixed in the second connector by the engagement of the positioning plate and the positioning slot. After the third connector is installed, the stamping block and the cutting blade are used to stamp the terminals on the stamping platform by driving the first connector through the stamping cylinder.

[0006] Furthermore, the inner wall of the second connector is provided with a plurality of limiting ring grooves coaxially arranged with the take-up groove, and the inner wall of the first mounting groove is provided with limiting ring blocks adapted to each limiting ring groove. The second connector is coaxially rotated within the first connector through the cooperation of the limiting ring blocks and the limiting ring grooves.

[0007] Furthermore, the aforementioned stamping platform is provided with multiple stamping bases, each stamping base having a lifting slide groove. Each lifting slide groove has a buffer rod, and each buffer rod has a buffer spring at its bottom. The two ends of the buffer spring are fixedly connected to the bottom of the lifting slide groove and the bottom of the buffer rod, respectively. Each buffer rod has a plastic buffer block at its top. The bottom of the third connecting body has buffer holes corresponding to each buffer block. Each buffer rod buffers the third connecting body through the cooperation between the buffer rod and the lifting slide groove, the continuous force of the buffer spring, and the cooperation between the buffer block and the buffer hole.

[0008] Furthermore, the first connecting body is provided with multiple vertically arranged guide rods, and the connecting plate is provided with multiple guide holes corresponding to each guide rod. The first connecting body is connected to the connecting plate for lifting and lowering by the drive of the stamping cylinder and the cooperation of each guide rod and guide hole.

[0009] Furthermore, the aforementioned work platform is also equipped with a control component for controlling the stamping section of the terminal block. The control component includes a control cylinder fixed on the work platform, an adjusting rod disposed at the telescopic end of the control cylinder and capable of extending into the terminal block, multiple limiting holes evenly distributed on the adjusting rod along the extension direction of the adjusting rod, and a limiting pin that can be inserted into any of the limiting holes. Each adjusting rod extends into the terminal block by being driven by the control cylinder, and the stamping section is controlled by the cooperation of each limiting pin and the limiting hole.

[0010] This utility model has the following positive effects: (1) By setting a stamping assembly at the output end of the stamping cylinder, the stamping assembly is configured as a first connecting body, a second connecting body and a third connecting body. The cooperation between the positioning shaft in the first connecting body and the connecting through hole in the rotating cylinder, as well as the continuous force of the torsion spring, ensures the smooth rotation of the second connecting body in the first mounting groove. At the same time, it can also ensure that after rotation, the second connecting body can be rotated to reset the pull rope. Through the cooperation between the connecting block on the second connecting body and the connecting groove, the quick connection and disassembly between the second connecting body and the third connecting body can be realized. At the same time, a positioning corresponding to the positioning shaft is set on the third connecting body. The plate, through the cooperation of the positioning plate and the positioning square groove, ensures the stability of the connection between the first and third connecting bodies, while not affecting the rotation of the second connecting body. This effectively solves the problem of cumbersome installation, disassembly, and replacement of stamping dies in existing technologies, which reduces efficiency. The cooperation of the first, second, and third connecting bodies greatly improves the efficiency and convenience of stamping die installation, disassembly, and replacement, while also ensuring the stability of the terminal block during the stamping process. In addition, through the cooperation of the stamping block and the cutting blade, the terminal block is precisely and efficiently positioned, stamped, and cut, improving the efficiency and quality of terminal block forming. The structure is ingenious, convenient, and practical.

[0011] (2) By setting a limiting ring groove on the outer wall of the second connector and setting a limiting ring block on the inner wall of the first mounting groove, the second connector can rotate smoothly and stably within the first connector through the cooperation of each limiting ring block and the limiting ring groove.

[0012] (3) By setting a stamping base on the stamping platform, each buffer rod buffers the third connecting body through the cooperation of the buffer rod and the lifting slide, the continuous force of the buffer spring, and the cooperation of the buffer block and the buffer hole. This can effectively buffer the impact force of the stamping head on the stamping platform and ensure the stability during the stamping process.

[0013] (4) By setting guide rods on the first connecting body and setting corresponding guide holes on the connecting plate, the stability of the first connecting body during the lifting process is greatly guaranteed through the cooperation of various guide rods and guide holes, which is efficient and convenient.

During installation, the operator can first pull the pull block 461, which extends the pull rope 46 and rotates the second connector 42. Simultaneously, the operator presses the third connector 43 upwards. During this pressing process, each connector block 424 enters the axial slot 44. Then, the operator releases the pull rope 46, which resets under the continuous force of the torsion spring 416. Then, each connector block 424 enters the circumferential slot 45, thereby realizing the connection between the stamping block 5 and the terminal block 43. The second connector 42 is quickly installed by setting a through groove at the bottom of the stamping block 5 that communicates with the positioning square groove 432. Then, the positioning plate 413 is fixed to the positioning shaft 412 by a locking device, thereby ensuring the stability of the connection between the third connector 43 and the first connector 41, and at the same time, it will not hinder the rotation of the second connector 42. During stamping, the stamping cylinder 31 drives the first connector 41 to descend. During the descent of the first connector 41, each guide rod 40 ensures the stability of the first connector 41 during the descent by cooperating with the guide hole. Then, while the stamping block 5 on the third connector 43 stamps the terminal block, the cutting blade 6 cuts the terminal block segment. On the one hand, it greatly improves the stability of the third connector 43 during installation or replacement, and on the other hand, it also ensures the stability during the stamping process, as well as the precise and efficient end stamping and cutting of the terminal block. The structure is ingenious, convenient and practical.
