Description

Technical Field

[0001] This utility model relates to the field of conductive terminal processing technology, and in particular to a coiling device for conductive terminals. Background Technology

[0002] In modern electronics manufacturing, conductive terminals are core components for achieving electrical connections, and their quality and processing efficiency are of paramount importance. In the production process, conductive terminals often require metal sheets to be rolled into a cylindrical shape so that they can be integrated with conductive terminals later.

[0003] A search revealed that Chinese Patent CN216773774U discloses a rolling device for conductive terminals. This device uses a drive mechanism to move a metal sheet into a rolling mechanism, which automatically rolls the sheet into a cylindrical shape. However, in actual operation, a cylinder drives a pressing tube to press the metal sheet into two sets of arc-shaped grooves. The rotation of the pressing tube causes the metal sheet to wrap around it, forming a rolled conductive terminal. This method involves a one-time extrusion molding process, which can cause surface damage to the conductive terminal due to excessive instantaneous pressure, thus compromising its surface quality and reducing its conductivity. Therefore, a rolling device for conductive terminals is urgently needed to solve these problems. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a drilling device for conductive terminals, so as to solve the technical problem that the surface damage of conductive terminals caused by the current one-time extrusion molding method is caused, thereby destroying the surface quality of conductive terminals and reducing their conductivity.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A coiling device for conductive terminals includes a worktable with a support on its surface and a pressing tube at the bottom of the support. A first drive plate and a second drive plate are slidably connected to the surface of the worktable. The inner sides of the first and second drive plates are arc-shaped, and the tops of the inner sides of the first and second drive plates are inclined. L-shaped rods are fixedly connected to both sides of the first and second drive plates. A slider is fixedly connected to one end of each L-shaped rod away from the first and second drive plates. A sliding groove is formed inside the worktable, with two sets of sliding grooves corresponding to each other. One end of each set of L-shaped rods extends through the sliding groove into the interior of the worktable and is movably connected thereto. A bidirectional screw is installed inside the worktable, and two sets of sliders are located on the outer surface of the bidirectional screw and are threadedly connected thereto.

[0008] As an improved technical solution, a motor is fixedly connected inside the worktable, and the output end of the motor extends to the inner side of the worktable and is fixedly connected to a bidirectional screw. A guide rod is also fixedly installed inside the worktable. The bidirectional screw and the guide rod are located on both sides of the first drive plate and the second drive plate, respectively. The other two sets of sliders are located on the outer surface of the guide rod and are slidably connected to it.

[0009] As an improved technical solution, a docking strip is fixedly connected to the inner side of the first drive plate. There are two sets of docking strips, which correspond to each other. Both sets of docking strips are located at the bottom of the first drive plate. A docking groove adapted to the docking strip is opened on the inner side of the second drive plate.

[0010] As an improved technical solution, a hydraulic cylinder is fixedly installed on the top of the bracket, a frame is provided on the inner side of the bracket, the output end of the hydraulic cylinder extends to the inner side of the bracket and is fixedly connected to the frame, the pressing tube is located on the inner side of the frame and is movably connected to it, a fixing frame is fixedly connected to one side of the frame, a motor is fixedly connected inside the fixing frame, and the output end of the motor extends to the inner side of the frame and is fixedly connected to the pressing tube.

[0011] As an improved technical solution, T-slots are provided on both sides of the first drive plate and the second drive plate. There are two sets of T-slots that correspond to each other. Limiting arc plates are provided on both sides of the first drive plate and the second drive plate. A T-block is fixedly connected to the inner side of the limiting arc plate. The T-block is located inside the T-slot and is slidably connected to it. The limiting arc plate is slidably connected to the first drive plate and the second drive plate through the T-block and the T-slot.

[0012] As an improved technical solution, a screw is rotatably connected to one end of the limiting arc plate, and a knob is fixedly connected to the other end of the screw. Threaded sleeves are fixedly connected to both sides of the first drive plate and the second drive plate. The threaded sleeves are located on the outer surface of the screw and are threadedly connected to it.

[0015] 1.

[0029] like Figures 1 to 5As shown in the figure, this embodiment provides a rolling hole device for conductive terminals. This rolling hole device for conductive terminals includes a worktable 1. The surface of the worktable 1 has a support 2. The bottom of the support 2 is provided with a pressing tube 3. A first driving plate 4 and a second driving plate 5 are slidably connected to the surface of the worktable 1. The inner sides of the first driving plate 4 and the second driving plate 5 are both arc-shaped, and the top of the inner sides of the first driving plate 4 and the second driving plate 5 are both inclined to facilitate the forming operation of conductive terminals.

[0030] Both sides of the first drive plate 4 and the second drive plate 5 are fixedly connected with L-shaped rods 10. The end of the L-shaped rod 10 away from the first drive plate 4 and the second drive plate 5 is fixedly connected with a slider 9. The inside of the worktable 1 is provided with a sliding groove 11. The sliding grooves 11 are in pairs and correspond to each other. One end of the multiple sets of L-shaped rods 10 extends into the inside of the worktable 1 through the sliding groove 11 and is movably connected to it.

[0031] The workbench 1 is equipped with a bidirectional screw 6 inside. Two sets of sliders 9 are located on the outer surface of the bidirectional screw 6 and are threadedly connected to it. The bidirectional screw 6 is rotatably connected to the workbench 1, which facilitates the movement of the first drive plate 4 and the second drive plate 5, and makes it easier for the first drive plate 4 and the second drive plate 5 to move closer or further away from each other.

[0032] A motor 7 is fixedly connected inside the workbench 1. The output end of the motor 7 extends to the inside of the workbench 1 and is fixedly connected to the bidirectional screw 6 so as to drive the rotation of the bidirectional screw 6.

[0033] Inside the workbench 1, a guide rod 8 is also fixedly installed. The bidirectional screw 6 and the guide rod 8 are located on the sides of the first drive plate 4 and the second drive plate 5, respectively. Two other sets of sliders 9 are located on the outer surface of the guide rod 8 and are slidably connected to it to maintain the stability of the first drive plate 4 and the second drive plate 5 when they move.

[0034] The inner side of the first drive plate 4 is fixedly connected with a docking strip 16. There are two sets of docking strips 16, which correspond to each other. Both sets of docking strips 16 are located at the bottom of the first drive plate 4. The inner side of the second drive plate 5 is provided with a docking groove 17 that matches the docking strip 16, which can provide support for the bottom of the conductive terminal and prevent the bottom from bulging when pressed.

[0035] A hydraulic cylinder 12 is fixedly installed on the top of the bracket 2. A frame 13 is provided on the inner side of the bracket 2. The output end of the hydraulic cylinder 12 extends to the inner side of the bracket 2 and is fixedly connected to the frame 13. The pressing tube 3 is located on the inner side of the frame 13 and is movably connected to it. The hydraulic cylinder 12 is used to drive the lifting operation of the pressing tube 3.

[0036] A fixed bracket 15 is fixedly connected to one side of the frame 13. A motor 14 is fixedly connected inside the fixed bracket 15. The output end of the motor 14 extends to the inside of the frame 13 and is fixedly connected to the pressing tube 3, which facilitates the rotation of the pressing tube 3 and improves the working efficiency and accuracy of the conductive terminal rolling hole.

[0037] Both sides of the first drive plate 4 and the second drive plate 5 are provided with T-slots 18. There are two sets of T-slots 18, which correspond to each other. Both sides of the first drive plate 4 and the second drive plate 5 are provided with limiting arc plates 19. T-blocks 23 are fixedly connected to the inner side of the limiting arc plates 19. The T-blocks 23 are located inside the T-slots 18 and are slidably connected to them. The limiting arc plates 19 are slidably connected to the first drive plate 4 and the second drive plate 5 through the T-blocks 23 and the T-slots 18. The limiting arc plates 19 can limit the two sides of the first drive plate 4 and the second drive plate 5 to avoid the conductive terminals from shifting during the rolling process, thereby ensuring the accuracy of the rolling process.

[0038] One end of the limiting arc plate 19 is rotatably connected to a screw 20, and the other end of the screw 20 is fixedly connected to a knob 22. Threaded sleeves 21 are fixedly connected to both sides of the first drive plate 4 and the second drive plate 5. The threaded sleeves 21 are located on the outer surface of the screw 20 and are threadedly connected to it to facilitate the positioning and driving operation of the screw 20.

[0039] The threaded sleeve 21 is located between the two sets of T-slots 18, which can ensure the stability of the limiting arc plate 19.

[0040] In use, the conductive terminal to be rolled is placed between the first drive plate 4 and the second drive plate 5. At the same time, the hydraulic cylinder 12 is activated to push the pressing tube 3 down to the top of the conductive terminal, that is, between the first drive plate 4 and the second drive plate 5. Then, the starting motor 7 drives the bidirectional screw 6 to rotate, and the two sets of sliders 9 bring the first drive plate 4 and the second drive plate 5 closer to each other. The plate-shaped conductive terminal slowly forms a V shape as the first drive plate 4 and the second drive plate 5 approach each other. At the same time, the motor 14 is activated to drive the pressing tube 3 to rotate, so that the conductive terminal slowly forms a tubular shape. When the first drive plate 4 and the second drive plate 5 are completely close, the conductive terminal can be formed by the rotation of the pressing tube 3. In this way, the damage caused by the one-time extrusion forming of the plate-shaped conductive terminal can be avoided.

[0041] Simultaneously, during operation, the knob 22 can be rotated to push the limiting arc plate 19 along the T-slot 18 through the T-block 23 towards the inner side of the first drive plate 4 and the second drive plate 5, until the limiting arc plate 19 moves to... Figure 2 This state can prevent the conductive terminals from slowly shifting away from the first drive plate 4 and the second drive plate 5 during the rolling process due to the rotation of the pressing tube 3.

[0042] At the same time, after the operation is completed, the knob 22 can be operated in reverse to make the screw 20 drive the limiting arc plate 19 to move towards the outside of the first drive plate 4 and the second drive plate 5. Then, the formed conductive terminal can be slid along the side between the first drive plate 4 and the second drive plate 5 to complete the unloading operation.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
