Description

Technical Field

[0001] This utility model relates to the field of terminal block manufacturing technology, specifically, an automatic stretching mold for terminal blocks. Background Technology

[0002] A terminal block is a component used for electrical connections, primarily to connect cables or wires to electrical equipment. It is typically made of metal with an insulated exterior to ensure safety and reliability. Terminal blocks come in various designs, including screw-type, plug-in type, and crimp type, suitable for different electrical systems. The working principle of a terminal block is to mechanically and securely fix the wire to the terminal, ensuring smooth current flow and preventing poor contact or current interruption. Common terminal blocks have wide applications, used in household appliances, industrial equipment, automotive circuits, and power systems.

[0003] Terminal block stretching dies are key tools used in the production of terminal blocks. Their main function is to process metal materials into the required terminal block shape through a stretching process. The working principle involves stretching a metal sheet through a die, undergoing a series of plastic deformations to ultimately form a terminal block.

[0004] In existing technology, when stamping and stretching the original sheet metal, the terminals are usually stretched into shape first, and then cut at the next station to separate them from the original sheet metal for unloading. This requires adding an extra station, lengthening the production line, increasing the floor space and volume, and extending the processing time, resulting in lower production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic stretching mold for terminal blocks, which solves the problems of multi-station operation, large equipment size, and low overall production efficiency in the production of terminal blocks in the prior art.

The synchronization spring is disposed between the roller frame and the push platform. A guide rod is mounted on the push platform and is slidably connected to the mounting frame. The roller frame is connected to the secondary die body or the secondary punch body. The push platform is connected to the main punch body or the main die body.

[0008] To better realize this utility model, the power unit further includes a hydraulic cylinder, a slide, and rollers. The hydraulic cylinder is mounted on the mounting frame, the slide is drivenly connected to the hydraulic cylinder, the slide is slidably connected to the mounting frame, and the rollers are rotatably connected to the roller frame. The slide and the rollers cooperate with each other.

[0009] To better realize this utility model, a return spring is further provided on the guide rod, and the other end of the return spring abuts against the mounting bracket.

[0010] To better realize this utility model, the main concave mold body and the main convex mold body are further equipped with connecting slide rods and corresponding insertion holes.

Detailed Implementation

[0028] 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.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Example 1:

[0031] This embodiment provides an automatic stretching mold for wiring terminals, specifically as follows: Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the assembly includes: a platform 10 and a mold assembly 30. The mold assembly 30 includes a punch unit and a die unit. The punch unit includes a main punch body 304, on which a punch component 306 is disposed. The die unit includes a main die body 301, on which a die component 308 is disposed. A secondary punch body 305 is slidably connected to the main punch body 304. The secondary punch body 305 is provided with a punch side cutting edge 307, which is located at the edge of the punch component 306. The main die body... A secondary die body 302 is slidably connected to 301. The secondary die body 302 is provided with a die-side cutting blade 309, which is located on the edge of the die part 308. The punch-side cutting blade 307 cooperates with the die-side cutting blade 309 to cut and blank the stretched terminal. It also includes a drive unit 20, which includes two symmetrically arranged drive units for driving the mold assembly 30 to run. The mold assembly 30 is mounted on the drive unit 20, and the drive unit 20 is mounted on the platform 10.

[0032] During operation, the worker places the sheet metal 40 between the punch unit and the die unit. Driven by the drive unit, the punch unit and die unit move closer together. At this time, the main punch body 304 and the auxiliary punch body 305 move synchronously, and the main die body 301 and the auxiliary die body 302 move synchronously. The punch part 306 compresses and stretches the sheet metal 40 to fit against the die part 308. When the main punch body 304 and the main die body 301 are completely pressed together, the punch part 306 and the die part 308 complete the stretching of the sheet metal 40, at which point the terminal block is formed. Afterwards, the main punch body 304 and the main die body 301 stop moving, and the drive unit continues to drive the auxiliary punch body 305. As the secondary die body 302 approaches each other, the punch-side cutting blade 307 and the die-side cutting blade 309 begin to protrude from the main punch body 304 and the main die body 301, thereby cutting the sheet metal 40. The punch-side cutting blade 307 is arranged horizontally, and the die-side cutting blade 309 is arranged vertically, without overlapping. Therefore, after the punch-side cutting blade 307 and the die-side cutting blade 309 cut the sheet metal 40, the stretched and formed terminal detaches from the sheet metal 40 and falls off. Then the drive unit resets, and the punch-side cutting blade 307 and the die-side cutting blade 309 reset to their non-protruding positions. Subsequently, the punch unit and the die unit reset synchronously.

[0033] By setting the main punch body 304, the punch side cutting blade 307, the secondary die body 302, and the die side cutting blade 309, the terminal block can be separated from the sheet 40 immediately after stretching and forming, realizing one-time forming and separation of the terminal block. Therefore, there is no need to add an additional cutting station to separate the terminal block, reducing the number of stations, reducing the space occupied, slowing down the processing cycle, and greatly improving the production efficiency of the terminal block.

[0034] In another specific embodiment, preferably, both the main concave mold body 301 and the main convex mold body 304 are equipped with a connecting slide rod 303 and a corresponding insertion hole. When the main convex mold body 304 and the main concave mold body 301 are close together, their respective connecting slide rods 303 are inserted into each other's insertion holes, thereby improving the alignment of the main concave mold body 301 and the main convex mold body 304, ensuring that the convex mold part 306 and the concave mold part 308 can better cooperate, preventing deviations between the two from causing substandard structure after the terminal block is formed, and improving the quality of the terminal block.

[0035] Example 2:

[0036] This embodiment further expands the driving unit based on the above embodiments, specifically as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the drive unit includes a mounting frame 201 and a power unit and a control unit mounted thereon. The control unit includes a roller frame 205, a synchronization spring 206, and a pusher platform 207. The power unit drives the roller frame 205 to move. The roller frame 205 is slidably connected to the pusher platform 207. The synchronization spring 206 is disposed between the roller frame 205 and the pusher platform 207. A guide rod 208 is mounted on the pusher platform 207 and is slidably connected to the mounting frame 201. The roller frame 205 is connected to the secondary die body 302 or the secondary punch body 305. The pusher platform 207 is connected to the main punch body 304 or the main die body 301.

[0037] When the power unit drives the roller frame 205, the roller frame 205 pushes the secondary die body 302 and the secondary punch body 305 to move. At the same time, the roller frame 205 transmits the force to the push table 207 through the synchronous spring 206. At this time, the main die body 301 and the main punch body 304 will also move synchronously with the secondary die body 302 and the secondary punch body 305. At this time, the punch part 306 and the die part 308 cooperate to stretch the plate 40 to form a terminal. When the main die body 301 and the main punch body 304 are in close contact, the pushing of the roller frame 205 causes the secondary die body 302 and the secondary punch body 305 to continue to move. However, the synchronous spring 206 begins to be compressed. The movement of the secondary die body 302 and the secondary punch body 305 causes the die-side cutting blade 309 and the punch-side cutting blade 307 to protrude and cut the plate 40, causing the formed terminal to detach from the plate 40 and fall off. This configuration allows a single power source to drive the main die body 301, the secondary die body 302, the main punch body 304, and the secondary punch body 305 in an orderly manner, reducing the number of power sources required, making the structure more compact, and reducing the overall volume.

[0038] Furthermore, the power unit includes a hydraulic cylinder 202, a slide 203, and a roller 204. The hydraulic cylinder 202 is mounted on the mounting bracket 201. The slide 203 is pulsatorically connected to the hydraulic cylinder 202 and slidably connected to the mounting bracket 201. The roller 204 is rotatably connected to the roller frame 205, and the slide 203 and the roller 204 cooperate with each other.

[0039] When the hydraulic cylinder 202 is started, it pushes the slide table 203 to slide on the mounting bracket 201. The slide table 203 presses the roller 204, and the roller 204 drives the roller frame 205 to move. Through the cooperation of the slide table 203 and the roller 204, the setting direction of the hydraulic cylinder 202 is perpendicular to the movement direction of the roller frame 205, so that it changes from a horizontal to a vertical setting, reducing the overall width and reducing the area occupied in the plane.

[0040] Furthermore, a return spring 209 is provided on the guide rod 208, and the other end of the return spring 209 abuts against the mounting bracket 201. When the hydraulic cylinder 202 drives the slide table 203 to retract and return to its original position, the return spring 209 enables the push table 207 and the roller frame 205 to also return synchronously, so that the punch unit and the die unit can automatically open the mold without manual control.

[0041] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0042] Example 3:

[0043] This embodiment further extends platform 10 based on the above embodiments, specifically as follows: Figure 2 , Figure 3 , Figure 10 As shown, the platform 10 includes a tabletop 101, on which a collection hopper 102 and a collection bin 103 are provided. A filter plate 104 is inclinedly arranged on the collection bin 103, and a discharge port and a chip discharge port are provided on the collection bin 103.

[0044] After the terminal block is cut off from the plate 40, it is collected by the collection hopper 102 and then falls onto the filter plate 104. At this time, the metal debris falls through the filter plate 104 to the bottom of the collection chamber 103, while the terminal block is discharged directly from the discharge port on the collection chamber 103 along the filter plate 104. After long-term use, the metal debris collected at the bottom of the collection chamber 103 can be cleaned from the chip discharge port.

[0045] Furthermore, the collection hopper 102 is equipped with multiple supports 107, which are used to support the plate 40 and guide and limit its movement. The supports 107 ensure that the plate 40 is fed along a predetermined route, preventing the plate 40 from falling, bending, or deviating.

[0046] Furthermore, two sets of feeding units are installed on the platform 10. Each feeding unit includes a feeding motor 106 and two feeding rollers 105. The sheet material 40 is positioned between the two feeding rollers 105. The feeding rollers 105 are rotatably connected to the table surface 101. The feeding motor 106 is driven by one of the feeding rollers 105. The feeding motor 106 intermittently drives the feeding rollers 105. When the feeding rollers 105 rotate, they feed the sheet material 40, thereby achieving automated continuous processing of the sheet material 40 and improving work efficiency.

[0047] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
