Description

Technical Field

[0001] This application relates to the field of wire and cable processing equipment technology, specifically a crimping device for wire and cable production. Background Technology

[0002] As a vital basic supporting industry in the national economy, wires and cables are widely used in various fields such as power, communications, transportation, and construction, and are indispensable key components for the normal operation of modern society. With the continuous development of the global economy, the acceleration of industrialization, and the rise of emerging industries, the market demand for wires and cables has shown a steady growth trend. In the production process, it is necessary to crimp terminals onto the ends of cables, requiring a crimping device for cable production.

[0003] Currently, when crimping terminals onto the ends of cables, the cable ends are usually placed manually into the crimping chamber of the crimping mechanism. This method has low crimping efficiency and poor accuracy in positioning the cable ends, making it difficult to accurately crimp the cable ends. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a crimping device for wire and cable production. This device automatically pushes the cable end into the crimping cavity of the crimping mechanism for terminal crimping, improving the efficiency of cable end terminal crimping. It also allows for precise placement of the cable end in the designated crimping position, enabling accurate terminal crimping of the cable end. This solves the current problem that cable end crimping typically involves manually inserting the cable end into the crimping cavity, resulting in low crimping efficiency and poor accuracy in positioning the cable end, making precise terminal crimping of the cable end difficult.

[0005] To achieve the aforementioned goal of automatically pushing the cable end into the crimping cavity of the crimping mechanism for terminal crimping, thereby improving the efficiency of cable end terminal crimping and accurately placing the cable end in the designated crimping position, this application provides the following technical solution: A crimping device for wire and cable production, comprising a base, a crimping mechanism mounted on the top of the base via support legs, an electric push rod mounted on the top of the base via a fixed frame, a material placement rack on one side of the crimping mechanism, multiple support sleeves mounted on the top of the material placement rack via a fixed frame, multiple cable placement seats slidably mounted on the inner side of the multiple support sleeves, a vertically penetrating limiting groove opened at the bottom of the support sleeve, a push frame mounted at the bottom of the cable placement seat, the push frame extending through the limiting groove at the bottom of the support sleeve to below the support sleeve, the push frame being L-shaped, with the end of the push frame away from the cable placement seat facing the electric push rod.

[0006] The above solution involves placing the cable requiring crimping into multiple cable holders on a material placement rack. An electric push rod then moves a pusher frame, causing the cable holders to move towards the crimping cavity of the crimping mechanism. This feeds the cable end into the crimping cavity for crimping, automatically pushing the cable end into the cavity and improving the efficiency of cable end crimping. Furthermore, it allows for precise placement of the cable end in the designated crimping position, ensuring accurate crimping of the cable end.

[0007] Furthermore, one end of the outer surface of the push frame is slidably disposed within the inner wall of the middle part of the limiting groove, and the length of the limiting groove does not completely penetrate the bottom of the supporting sleeve.

[0008] The above solution limits the movement distance of the push frame by the end of the limiting groove, thereby limiting the distance that the push frame can move the cable placement seat, and preventing the cable placement seat from sliding out of the inside of the support sleeve when it slides inside the support sleeve.

[0009] Furthermore, a limiting plate is provided on the outer surface of one end of the push frame. The limiting plate is arc-shaped, and the specifications of the top arc-shaped outer surface of the limiting plate are adapted to the specifications of the bottom outer surface of the support sleeve. The top outer surface of the limiting plate and the bottom outer surface of the support sleeve are slidably connected.

[0010] The above solution, through the setting of the limiting plate, can restrict the sliding trajectory of the cable placement seat in conjunction with the push frame, so that the cable placement seat can be tightly attached to the inner side of the support sleeve, preventing the cable placement seat from separating from the support sleeve and improving the stability of the cable placement seat when moving.

[0011] Furthermore, a first magnet is provided at one end of the push frame near the electric push rod, and a second magnet is provided at one end of the electric push rod near the push frame, with the first magnet and the second magnet attracting each other.

[0012] With the above scheme, the first magnet and the second magnet attract each other, so that the electric push rod can be reset by the first magnet and the second magnet pulling the push frame to reset, thereby driving the cable placement seat away from the pressing mechanism to reset, so that the cable end after the pressing terminal can be moved out of the pressing cavity of the pressing mechanism.

[0013] Furthermore, the bottom of the material placement rack is provided with a rack, which meshes with a gear. The gear is located at one end of the motor shaft, and the bottom of the motor is mounted on the top of the base via a fixing block. The gear is a half-gear.

[0014] The above solution utilizes a motor to drive a gear, which in turn moves a rack, thereby moving the material placement rack. This adjusts the position of the material placement rack on one side of the pressing mechanism, allowing the continuously moving unpressed cables to the pressing chamber of the pressing mechanism. The half-gear configuration of the gear enables the gear to move the material placement rack intermittently via the rack, providing sufficient pressing time for the pressing mechanism and preventing the pressing position from shifting or the pressing action from failing to complete properly due to the continuous movement of the material placement rack.

[0015] Furthermore, two slide bars are provided on both sides of the bottom of the material placement rack. The two slide bars are slidably disposed in the middle inner wall of the two supporting slide frames. The bottom of the supporting slide frames is disposed on the top of the base through supporting legs.

[0016] The above solution uses a slider that slides within the inner wall of the middle section of the support frame to fix the trajectory of the material placement rack, thereby improving the stability of the material placement rack during movement.

[0017] Furthermore, a pressing support is provided at the bottom of the inner wall of the pressing cavity of the pressing mechanism via a fixing block. One end of the pressing support extends to the outside of the pressing cavity of the pressing mechanism. The end face of the pressing support slides in contact with the end face of the supporting sleeve. The setting height of the pressing support and the supporting sleeve are corresponding.

[0018] The above scheme connects one end of the pressing support with one end of the supporting sleeve, allowing the exposed cable end of the cable placement seat to slide smoothly into the pressing support through the supporting sleeve. This guides the movement trajectory of the exposed cable end on the outside of the cable placement seat, enabling the cable end to smoothly enter the designated pressing position in the pressing cavity of the pressing mechanism.

[0019] Furthermore, the outer surface of the slider is convex, and the shape of the outer surface of the slider is adapted to the shape of the inner wall of the middle part of the support slider frame, and the two ends of the support slider frame are open.

[0020] The above solution restricts the vertical movement of the slide bar within the support frame by matching the shape of the support frame and the slide bar, thus fixing the height of the material placement rack and further improving its stability during movement. The open design at both ends of the support frame allows the slide bar of the material placement rack to slide in or out easily, facilitating its installation and removal. Furthermore, after the cables on the material placement rack are crimped, the rack can be easily replaced, allowing for quick replacement of the next batch of uncrimped cables.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This wire and cable crimping device places the cable requiring crimping into multiple cable holders on a material placement rack. An electric push rod then moves a push frame, causing the cable holders to move towards the crimping cavity of the crimping mechanism. This feeds the cable end into the crimping cavity for crimping, automatically pushing the cable end into the cavity and improving the efficiency of cable end crimping. Furthermore, it accurately places the cable end in the designated crimping position, ensuring precise crimping of the cable end. Attached Figure Description

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a wire and cable production crimping device includes a base 1. A crimping mechanism 2 is mounted on the top of the base 1 via a support leg. An electric push rod 7 is mounted on the top of the base 1 via a fixed frame. A material placement rack 3 is provided on one side of the crimping mechanism 2. Multiple support sleeves 4 are mounted on the top of the material placement rack 3 via a fixed frame. Multiple cable placement seats 5 are slidably mounted on the inner side of the multiple support sleeves 4. A vertically penetrating limiting groove 8 is opened at the bottom of the support sleeves 4. A push frame 6 is provided at the bottom of the cable placement seat 5. The push frame 6 extends through the limiting groove 8 at the bottom of the support sleeves 4 to the bottom of the support sleeves 4. The push frame 6 is L-shaped, with the end of the push frame 6 away from the cable placement seat 5 facing the electric push rod 7.

[0034] Please see Figure 6 and Figure 7 One end of the push frame 6 is slidably disposed in the middle inner wall of the limiting groove 8. The length of the limiting groove 8 does not completely penetrate the bottom of the support sleeve 4. The movement distance of the push frame 6 can be limited by the end of the limiting groove 8, thereby limiting the distance that the push frame 6 can drive the cable placement seat 5 to move, and preventing the cable placement seat 5 from sliding out of the inner side of the support sleeve 4 when it slides inside the support sleeve 4.

[0035] Please see Figure 2 , Figure 6 and Figure 7A limiting plate 9 is provided on the outer surface of one end of the push frame 6. The limiting plate 9 is arc-shaped. The specifications of the top arc-shaped outer surface of the limiting plate 9 are adapted to the specifications of the bottom outer surface of the support sleeve 4. The top outer surface of the limiting plate 9 is slidably connected to the bottom outer surface of the support sleeve 4. The setting of the limiting plate 9 can cooperate with the push frame 6 to restrict the sliding trajectory of the cable placement seat 5, so that the cable placement seat 5 can be tightly attached to the inner side of the support sleeve 4, preventing the cable placement seat 5 from separating from the support sleeve 4 and improving the stability of the cable placement seat 5 when it moves.

[0036] Please see Figure 1 , Figure 2 and Figure 3 A first magnet 10 is provided at one end of the push frame 6 near the electric push rod 7, and a second magnet 11 is provided at one end of the electric push rod 7 near the push frame 6. The first magnet 10 and the second magnet 11 attract each other. By attracting each other, the electric push rod 7 can pull the push frame 6 to reset through the first magnet 10 and the second magnet 11. This will drive the cable placement seat 5 away from the pressing mechanism 2 to reset, so that the cable end after the pressing terminal can be moved out of the pressing cavity of the pressing mechanism 2.

[0037] Please see Figure 2 , Figure 3 and Figure 5 The bottom of the material placement rack 3 is provided with a rack 14, which meshes with a gear 15. The gear 15 is located at one end of the motor shaft of the motor 16. The bottom of the motor 16 is fixed to the top of the base 1 by a fixing block. The gear 15 is a half gear. When the motor 16 works, it can drive the gear 15 to rotate, which in turn drives the rack 14 to move, thereby moving the material placement rack 3. Adjusting the position of the material placement rack 3 on one side of the pressing mechanism 2 can move the continuously unpressed cable to the pressing cavity of the pressing mechanism 2. The half gear setting of the gear 15 allows the gear 15 to drive the material placement rack 3 to move intermittently through the rack 14, providing sufficient pressing time for the pressing mechanism 2 and avoiding the pressing position deviation or the inability to complete the pressing action due to the continuous movement of the material placement rack 3.

[0038] Please see Figure 1 , Figure 2 and Figure 3 The bottom sides of the material placement rack 3 are provided with two slide bars 12. The two slide bars 12 are respectively slidably disposed in the middle inner wall of the two support slide frames 13. The bottom of the support slide frame 13 is disposed on the top of the base 1 through support legs. By sliding the slide bars 12 in the middle inner wall of the support slide frame 13, the movement trajectory of the material placement rack 3 can be fixed, thereby improving the stability of the material placement rack 3 when it moves.

[0039] Please see Figure 1 , Figure 3and Figure 4 A pressing support 17 is provided at the bottom of the inner wall of the pressing cavity of the pressing mechanism 2 via a fixing block. One end of the pressing support 17 extends to the outside of the pressing cavity of the pressing mechanism 2. The end face of the pressing support 17 slides in contact with the end face of the support sleeve 4. The setting height of the pressing support 17 and the support sleeve 4 are corresponding. By connecting one end of the pressing support 17 with one end of the support sleeve 4, the exposed cable end of the cable placement seat 5 can smoothly slide into the pressing support 17 through the support sleeve 4. The movement trajectory of the exposed cable end on the outside of the cable placement seat 5 is guided so that the cable end can smoothly enter the designated pressing position in the pressing cavity of the pressing mechanism 2.

[0040] Please see Figure 1 , Figure 3 and Figure 5 The outer surface of the slide bar 12 is convex, and its shape matches the shape of the inner wall of the middle part of the support slide frame 13. The two ends of the support slide frame 13 are open. The shape of the support slide frame 13 and the slide bar 12 can restrict the vertical movement of the slide bar 12 within the support slide frame 13, which can fix the height of the material placement rack 3 and further improve the stability of the material placement rack 3 when it moves. At the same time, the open shape of the two ends of the support slide frame 13 can make it easy for the slide bar 12 of the material placement rack 3 to slide in or out from the end of the support slide frame 13, which is convenient for installing and disassembling the slide bar 12. After the cable on the material placement rack 3 is crimped, the material placement rack 3 can be easily replaced, and the next batch of uncrimped cables can be quickly replaced.

[0041] This embodiment of a wire and cable crimping device involves placing the cable requiring crimping into multiple cable placement seats 5 on a material placement rack 3. An electric push rod 7 then operates, pushing a push frame 6. This push frame 6 moves the cable placement seats 5 towards the crimping cavity of the crimping mechanism 2, feeding the cable end placed on the cable placement seat 5 into the crimping cavity of the crimping mechanism 2 for crimping. This achieves the effect of automatically pushing the cable end into the crimping cavity of the crimping mechanism 2 for crimping, improving the efficiency of cable end crimping, and accurately placing the cable end in the designated crimping position, thus achieving precise crimping of the cable end.

[0042] The working principle of the above embodiment is as follows: The cable requiring crimped terminals is placed on the cable placement seat 5, with the cable end exposed on the outer side of the cable placement seat 5 near the crimping mechanism 2. The cable end rests on the inner side of the support sleeve 4. The slide bar 12 at the bottom of the material placement rack 3 containing the cable slides into the support frame 13 from the opening at one end, completing the installation of the material placement rack 3. The material placement rack 3 is then pushed to move, causing the rack 14 to move to the designated position. The motor 16 operates, driving the gear 15 to rotate. The gear 15, with its half-gear configuration, cooperates with the rack 14 to drive the material placement rack 3 to move intermittently. When the material placement rack 3 stops moving due to the gear 15 cooperating with the rack 14, the cable without crimped terminals is located in the crimping cavity of the crimping mechanism 2. Simultaneously, the corresponding support sleeve 4 engages with the crimping support 17. The electric push rod 7 operates, driving the second magnet 11 to move towards the first magnet 10, causing the first magnet 10 and the second magnet 11 to attract each other. The second magnet 11, in conjunction with the first magnet 10, pushes the pusher 6, causing the pusher 6 to slide the cable placement seat 5 against the pressing mechanism 2 inside the support sleeve 4. This causes the end of the cable to slide from the inside of the support sleeve 4 into the pressing support 17. The pressing mechanism 2 then operates to press the cable end on the pressing support 17 to form a terminal. After pressing, the electric push rod 7 resets and, through the second magnet 11 and the first magnet 10, pulls the pusher 6 to move, causing the cable placement seat 5 to move away from the pressing mechanism 2. This pulls the cable end after the terminal is formed out of the pressing cavity of the pressing mechanism 2. When the pusher 6 is blocked by the end of the limiting groove 8, the pusher 6 stops moving. The reset of the electric push rod 7 causes the first magnet 10 to separate from the second magnet 11. The continuous rotation of the gear 15 causes the teeth of the gear 15 to mesh with the rack 14 again. This, in turn, pushes the material placement frame 3 to move again through the rack 14, pushing the next cable that needs to be pressed to the pressing cavity of the pressing mechanism 2.
