Description

Technical Field

[0001] This utility model relates to the field of pressing structure technology, specifically a terminal machine pressing structure. Background Technology

[0002] Terminal crimping machines are commonly used in wire processing. They are mainly used to crimp metal terminals onto the ends of wires to achieve conductivity. The crimped terminals typically do not require soldering, making them convenient to use and easy to remove. The working principle of a terminal crimping machine is based on precise pressure and displacement control to crimp terminals onto wires and cables. During the crimping process, each terminal connected by metal plates is fed one by one to the bottom of the crimping head. The wire or cable to be processed is then introduced into the crimping structure, where the terminals are stably crimped onto the wire or cable. After crimping, the metal connecting plates on both sides of the terminal are cut off. However, after crimping with the cable, the terminals are prone to sticking to the inside of the crimping head due to the pressure, which can cause jamming. Removing the crimped terminals and cables is also inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a terminal crimping structure to solve the problems mentioned in the background art, such as the terminal sticking to the inside of the crimping joint due to the pressure of the crimping joint after crimping with the cable, which can easily cause the terminal to jam after crimping and make it inconvenient to remove the crimped terminal and cable.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a terminal crimping structure, comprising:

[0005] Support frame;

[0006] A support base plate is installed on top of the support base frame;

[0007] A pressing base is installed on top of the supporting base plate;

[0008] A support frame is installed on top of the support base frame;

[0009] Hydraulic cylinder, the hydraulic cylinder is mounted on the top of the support frame;

[0010] The movable support plate is located at the output end of the hydraulic cylinder.

[0020] As a preferred embodiment of this utility model, a support plate is fixedly connected between the first support block and the second support block.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting a movable support plate, a crimping connector, and a cutting head, enables the movable support plate to drive the crimping connector and cutting head at the bottom to move downward. By cooperating with the pressing base at the top of the supporting base plate, the crimping connector presses the terminals and cables on the pressing base, and the cutting head on one side of the crimping connector cuts the metal parts connecting each terminal, removing the metal parts between two adjacent terminals. After pressing, the cables and terminals are removed together. By setting a spring, a limiting slide plate, a sliding plate, and a lower top plate, during pressing, the lower top plate moves upward, driving the sliding plate and the limiting slide plate to move upward.

[0027] 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.

[0028] Please see Figures 1 to 4This utility model provides a technical solution: a terminal crimping structure, comprising: a support base frame 1; a support base plate 18 fixedly connected to the top of the support base frame 1; a crimping base 11 fixedly connected to the top of the support base plate 18; a support frame 4 fixedly connected to the top of the support base frame 1; a hydraulic cylinder 5 mounted on the top of the support frame 4; a movable support plate 6 fixedly connected to the output end of the hydraulic cylinder 5; a crimping connector 8 fixedly connected to the bottom of the movable support plate 6, the crimping connector 8 cooperating with the crimping base 11; and a cutting head 9 fixedly connected to one side of the crimping connector 8. The top of the cutting head 9 is fixedly connected to the movable support plate 6; the fixed side box 19 is fixedly connected to one side of the crimping head 8 and the cutting head 9, and the fixed side box 19 is slidably provided with a limiting slide plate 20 inside; the sliding plate 22 is fixedly connected to the bottom of the limiting slide plate 20, and the sliding plate 22 is slidably connected to the fixed side box 19, and the bottom of the sliding plate 22 is fixedly connected to the bottom plate 23; the springs 21 are equidistantly arranged inside the fixed side box 19, one end of the spring 21 is fixedly connected to the fixed side box 19, and the other end of the spring 21 is fixedly connected to the limiting slide plate 20.

[0029] It is understood that this utility model is powered by an external power source. The output of the motor 15 drives the bidirectional lead screw 14 to rotate. When the bidirectional lead screw 14 rotates, it drives the outer movable slider 16 to move and adjust. When the movable slider 16 moves, it drives the guide baffle 17 on the top of the first support block 2 to move. The two guide baffles 17 guide the terminals conveyed on the first support block 2 to a position below the crimping connector 8. Adjacent terminals are connected and conveyed together by metal sheets. When one terminal is above the crimping base 11, the cable crimped by the terminal moves to the support plate 10, inside the terminal on the crimping base 11. Then, during crimping, the output of the hydraulic cylinder 5 drives the movable support plate 6, crimping connector 8, and cutting head 9 to move downwards. The crimping connector 8 crimps the terminal and the cable. The cables are crimped together. The cutting head 9 on one side of the crimping connector 8 cuts the metal plates on both sides of the crimped terminal, and cuts the metal connecting plates between adjacent terminals by punching. During the crimping process, when the lower top plate 23 contacts the terminal and cable, the lower top plate 23 moves upward under force, which drives the sliding plate 22 and the limiting slide plate 20 to move upward. The limiting slide plate 20 presses the springs 21 in the fixed side box 19. After the crimping is completed, the output end of the hydraulic cylinder 5 drives the moving support plate 6 to move upward. The moving support plate 6 drives the crimping connector 8 and the cutting head 9 to move upward. At this time, the springs 21 reset and drive the limiting slide plate 20, the sliding plate 22 and the lower top plate 23 to reset downward. The lower top plate 23 pushes the crimped terminal and cable to prevent the terminal from sticking to the inside of the crimping connector 8, so that the terminal and cable can be crimped and discharged.

[0030] Please see Figures 1 to 3It also includes a first support block 2, which is fixed to the top of the support base plate 18. A second support block 3 is fixed to the top of the support base plate 18. The pressing base 11 is located between the first support block 2 and the second support block 3. A guide baffle 17 is symmetrically slidably arranged on the top of the first support block 2.

[0031] It is understood that the present invention guides the terminal conveying position through the guide baffles 17 symmetrically arranged on the top of the first support block 2, so that the terminal is pressed at the top position of the pressing base 11.

[0032] Please see Figures 1 to 3 The first support block 2 is internally rotatably connected to a bidirectional lead screw 14. The outer side of the bidirectional lead screw 14 is symmetrically threaded with a movable slider 16. The movable slider 16 is slidably connected to the first support block 2. The top of the movable slider 16 is fixedly connected to the guide baffle 17. A motor 15 is installed on one side of the first support block 2. The output end of the motor 15 is fixedly connected to the bidirectional lead screw 14.

[0033] It is understood that the present invention drives the bidirectional lead screw 14 to rotate through the output end of the motor 15. When the bidirectional lead screw 14 rotates, it drives the symmetrically moving slider 16 on the outside to move. When the moving slider 16 moves, it drives the guide baffle 17 on the top of the first support block 2 to move, and adjusts the guide according to different terminals.

[0034] Please see Figures 1 to 3 The outer side of the pressing base 11 is symmetrically fixed with waste guide blocks 12. The bottom of the waste guide blocks 12 is fixedly connected to the support base plate 18. The support base frame 1 and the support base plate 18 are both provided with waste discharge ports 13 that cooperate with the waste guide blocks 12.

[0035] It is understood that, in this invention, when the terminal and cable are pressed together, the cutting head 9 simultaneously cuts the metal connectors connecting the terminals, and the cut metal is discharged through the waste discharge port 13.

[0036] Please see Figures 1 to 3 The top of the movable support plate 6 is symmetrically fixed with a limiting slide rod 7, and the limiting slide rod 7 is slidably connected to the support frame 4.

[0037] It is understood that this utility model uses the output end of the hydraulic cylinder 5 to drive the movable support plate 6 to adjust its up and down position. When the movable support plate 6 moves up and down, it drives the top limiting slide rod 7 to move. The limiting slide rod 7 slides within the support frame 4 to limit the movement and ensure the stability of the movement of the movable support plate 6, the crimping head 8 and the cutting head 9.

[0038] Please see Figures 1 to 3 A support plate 10 is fixed between support block 2 and support block 3.
