Description

Technical Field

[0001] The present application relates to the field of wire processing, and in particular to a crimping device that combines wire stripping and crimping. Background Art

[0002] Crimping refers to a technique that uses tools or equipment to compress and displace metal within specified limits and connect wires to terminals.

[0003] In the prior art, such as a wire stripping and crimping machine with patent application number CN219917867U, an injection molding machine uses large-diameter wires as power lines. These wires need to be installed with terminals for easy use. Before installing the terminals, the insulating sheath of the wires needs to be stripped off first, and then the terminals are put on the wires, and then the terminals are crimped and fixed on one end of the wires. After crimping, tin is poured to enhance the stability of the connection between the terminals and the wires.

[0004] Generally, wire stripping is done manually with the help of tools such as wire strippers, and then the terminals are crimped. After crimping, tin is poured manually. This work is inefficient, time-consuming and labor-intensive, and there is room for improvement. Utility Model Content

[0005] In order to improve the convenience and efficiency of terminal installation, the present application provides a crimping device that combines wire stripping and crimping.

[0006] A crimping device that combines wire stripping and crimping, comprising a base, on which a stripping mechanism for stripping the wire end and a crimping mechanism for crimping and fixing a terminal to the stripped end of the wire are arranged;

[0007] The stripping mechanism comprises a stripping knife and a stripping cylinder. The stripping knife moves towards or away from each other and cuts off the outer skin of the wire after approaching and fits with the core gap of the wire. The stripping cylinder is symmetrically arranged on the base and is used to drive the stripping knife to move towards or away from each other.

[0008] The crimping mechanism comprises a crimping assembly and a crimping motor. The crimping assembly is arranged on the base for opening and closing and crimps the terminal onto one end of the stripped wire after closing. The crimping motor is arranged on the base and is used to drive the crimping assembly to open and close.

[0009] By adopting the above technical solution, the stripping knife is driven by the stripping cylinder to clamp the insulating sheath of the wire, thereby facilitating the stripping of the insulating sheath. After the sheath is stripped, the terminal is manually put on the wire, and then the crimping motor drives the crimping assembly to crimp and fix the terminal on the wire, thereby improving the convenience of terminal installation and improving the terminal installation efficiency.

[0010] Preferably, a first movable limiting mechanism is provided on the base at an end of the stripping mechanism away from the crimping mechanism and one end of the limiting wire is transported or withdrawn to the stripping mechanism or the crimping mechanism.

[0011] By adopting the above technical solution, one end of the wire is driven to slide on the base through the first movable limiting mechanism, so that one end of the wire is controlled to approach the stripping mechanism first, and then the one end of the wire is controlled to move away from the stripping mechanism after the stripping cylinder drives the stripping knife to press the wire, thereby completing the stripping.

[0012] Preferably, the first movable limiting mechanism includes a slide seat guided to move on the base and capable of approaching or moving away from the stripping mechanism, a driving mechanism driving the slide seat to move and to be in a limited state after the movement, and an end limiting mechanism arranged on the slide seat for limiting one end of the wire.

[0014] Preferably, the end limiting mechanism comprises a bracket fixed on the slide and a wire pressing cylinder fixed on the bracket, the cylinder body of the wire pressing cylinder is fixed on the bracket and the piston rod faces one end close to the slide.

[0015] By adopting the above technical solution, the piston rod of the wire pressing cylinder presses against the slide seat, thereby pressing and fixing the wire on the slide seat, thereby reducing the situation where the wire slips during stripping and causes stripping failure, and improving the convenience of using the wire stripping mechanism.

[0016] Preferably, the driving mechanism includes a driving block with a threaded hole arranged at the lower end of the slide and a screw rod rotatably arranged on the base and screwed to the threaded hole, and a guide mechanism is arranged between the slide and the base to drive the slide to slide along the axial direction of the screw rod.

[0017] By adopting the above technical solution, when the screw rod rotates, the driving block is driven to slide on the screw rod, thereby driving the slide seat to slide on the base along the length direction of the screw rod, thereby controlling the first movable limit mechanism to approach or move away from the stripping mechanism, thereby realizing the automatic wire stripping process and improving the convenience of using the wire stripping mechanism.

[0018] Preferably, the guide mechanism comprises a guide rail extending along the conveying direction of the electric wire at the upper end of the base and a slider fixed at the lower end of the slide seat and embedded in the guide rail.

[0019] By adopting the above technical solution, the guide rail and the slider are pressed against each other, thereby reducing the possibility of the slider detaching from the guide rail, thereby limiting the sliding direction of the slide on the base, reducing the wear of the lead screw caused by the deviation of the slide when sliding, and improving the stability of the mobile mechanism.

[0020] Preferably, a wire feeding mechanism for automatically feeding the wires to the stripping mechanism and the crimping mechanism is provided on the side of the end limiting mechanism away from the stripping mechanism on the slide seat.

[0021] By adopting the above technical solution, the wire is driven to slide on the slide seat by the wire feeding mechanism, so as to enter the stripping mechanism or the crimping mechanism, thereby controlling the length of the outer skin stripped from the wire and accurately crimping it, thereby improving the stability of terminal installation.

[0022] Preferably, the wire feeding mechanism includes parallely arranged mounting plates, a wire feeding belt assembly arranged on the side opposite to the mounting plates and transmitting along the wire conveying direction, and a belt cylinder arranged on the slide seat for driving the mounting plates closer to or away from each other to achieve the abutment or separation of the wire feeding belt assembly and the wire to be conveyed.

[0023] By adopting the above technical solution, the wire is driven to slide on the slide seat through the wire feeding belt assembly, thereby adjusting the length range of the wire peeling, and sending the wire into the position where the pressure wire cylinder is pressed, thereby improving the convenience of using the first movable limiting mechanism.

[0024] Preferably, the wire feeding belt assembly comprises rollers arranged in parallel and at intervals and belts tensioned on the rollers, and a belt motor is provided on one of the rollers to drive the roller to rotate.

[0025] Preferably, a second movement limiting mechanism having the same structure as the first movement limiting mechanism is provided on a side of the crimping mechanism away from the stripping mechanism.

[0026] By adopting the above technical solution, after the wire feeding belt of the first movable limiting mechanism drives the wire to move forward a proper distance, the outer skin of one end of the wire is peeled off by the stripping mechanism and the crimping mechanism respectively, and then the terminal is crimped and fixed. After the crimping is completed, the wire is driven by the wire feeding belt to continue moving forward to the second movable limiting mechanism on the other side, and the other end of the wire is fixed on the first movable limiting mechanism on the other side, and then the outer skin of the other end of the wire is stripped off and the terminal is crimped and fixed, thereby completing the stripping and crimping fixation of both ends of the wire, thereby improving the convenience of using the crimping equipment.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The stripping cylinder drives the stripping knife to clamp the insulation sheath of the wire, so as to facilitate the stripping of the insulation sheath. After the sheath is stripped, the terminal is manually put on the wire, and then the crimping motor drives the crimping assembly to crimp and fix the terminal on the wire, thereby improving the convenience of terminal installation and improving the efficiency of terminal installation;

[0029] 2. The wire is driven to slide on the slide seat by the wire feeding belt assembly, thereby adjusting the length range of the wire skin stripping, and the wire is sent to the position where the pressure wire cylinder presses, thereby improving the convenience of using the first movable limit mechanism;

[0030] 3. When the screw rotates on the mounting block, the driving block is driven to slide on the screw, thereby driving the slide seat to slide on the base along the length direction of the screw, thereby controlling the first movable limit mechanism to approach or move away from the stripping mechanism, thereby realizing the automatic stripping process and improving the convenience of using the stripping mechanism.
