Abstract

The present invention relates to a tin-plated soft copper wire stranding device in the technical field of wire stranding equipment, including a chassis, a finger cylinder, and a driving member for driving the rotation of the finger cylinder. The first finger and the second finger are driven to move relative to each other by a cylinder slide, so that the two clamping grooves approach each other, and thus effectively clamp the copper wire inside the clamping grooves through the limiting protrusions. Closing baffles are provided on both the top end surface and the bottom end surface of the second finger. One side of the closing baffle extends towards the clamping groove, and the closing baffle can cover the upper part between the first finger and the second finger. When the closing baffle covers the inner side wall of the first finger, a sealed isolation cavity can be formed, making it difficult for the copper wire to be exposed outside the finger cylinder, avoiding the copper wire being easily wound inside the rotary drive assembly of the copper wire stranding equipment, preventing the copper wire stranding equipment from easily malfunctioning, and improving the qualified rate of tin-plated soft copper wire stranding.

Description

Technical Field

[0001] The present invention relates to the technical field of wire stranding equipment, and specifically relates to a tin-plated soft copper wire stranding device. Background Art

[0002] Stranded copper wire is a wire formed by stranding multiple copper wires together. Such a structure can not only greatly increase the flexibility of the cable, but also make the curvature during bending not concentrated at one point, but distributed on each copper wire, greatly increasing the durability of the copper wire. And a stranding machine is a mechanical equipment that can be widely used in the stranding of various soft and hard conductor wires and electronic wires, twisting multiple single-conductor wires into one strand to meet the process requirements of the wire.

[0003] When clamping the copper wire during feeding in the existing copper wire stranding equipment, it is easy for some copper wires to be exposed outside the finger cylinder, making the copper wires easily wound inside the rotary drive assembly of the copper wire stranding equipment, which makes the copper wire stranding equipment prone to failure. At the same time, the qualified rate of copper wire stranding is also relatively low. Summary of the Invention

[0004] The object of the present invention is to solve the above defects and provide a tin-plated soft copper wire stranding device.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A tin-plated soft copper wire stranding device includes a chassis, a finger cylinder, and a driving member for driving the rotation of the finger cylinder. The finger cylinder is composed of a cylinder body, a cylinder slide, and a clamping assembly. The clamping assembly includes a first finger and a second finger. Clamping grooves are provided on the inner side walls of both the first finger and the second finger. One end of the clamping groove on the inner side wall of the first finger is provided with a limiting convex block protruding outward. A clearance fit can be carried out between the limiting convex block and the clamping groove on the inner side wall of the second finger. Closing baffles are provided on both the top end face and the bottom end face of the second finger. One side of the closing baffle extends towards the clamping groove, and the closing baffle can cover the upper part between the first finger and the second finger.

[0007] In the above description, as a further solution, the inner wall of the clamping groove is an arc structure, and the surface of the limiting convex block in contact with the clamping groove is an arc structure matching the inner wall of the clamping groove. By driving the first finger and the second finger to move relative to each other through the cylinder slide, the two clamping grooves approach each other, and then the copper wire is clamped inside the clamping groove through the limiting convex block.

[0008] In the above description, as a further solution, the middle part of the closing baffle is an upwardly convex arc structure. Due to the arc structure of the closing baffle, when the closing baffle covers the inner side wall of the first finger, a sealed isolation cavity can be formed, making it difficult for the copper wire to be exposed outside the finger cylinder.

[0009] In the above description, as a further solution, two chutes for installing the cylinder slide are provided on the front end face of the cylinder block. The cylinder slides are respectively slidably connected to the inside of the chutes. One ends of the first finger and the second finger are respectively fixedly connected to the cylinder slides. Through the chutes provided on the front end face of the cylinder block, the cylinder slides can slide along the inside of the chutes, making the docking and clamping between the first finger and the second finger more accurate.

[0010] In the above description, as a further solution, the bottom of the cylinder block is a pipe base. The pipe base is screwed and fixed to the driving member through fixing bolts. An air inlet nozzle for connecting an external air supply component is provided on one side of the cylinder block. The air inlet nozzle is connected in communication with the inside of the cylinder block. Air is supplied into the cylinder block through the air inlet nozzle on one side of the cylinder block, so that the cylinder slide can move along the chute by the push of the gas. At the same time, when the air pressure inside the cylinder block is large enough, the copper wire can be clamped more firmly between the first finger and the second finger.

[0011] In the above description, as a further solution, the driving member is composed of a driving motor. A rotatable rotating base is provided on the front end face of the driving motor. One end of the finger cylinder far from the clamping component is fixedly connected to the rotating base. The driving motor is fixedly connected inside the chassis. The rotating base penetrates to the front end face of the chassis. The driving motor drives the rotating base to rotate around the center of the driving motor, so that the rotating base can drive the finger cylinder to rotate, and the copper wire clamped inside the finger cylinder can be twisted through the driving motor.

[0012] In the above description, as a further solution, a control panel for controlling the finger cylinder and the driving member is also provided on the front end face of the chassis. The control panel is electrically connected to the driving member. The working sequence of the driving member and the finger cylinder is controlled through the control panel, so that the finger cylinder and the driving member can cooperate with each other to complete the automatic copper wire twisting process.

[0013] In the above description, as a further solution, a power interface for providing driving power is provided on the back of the chassis, and a start switch for controlling the driving member and the control panel is provided on the back of the chassis.

[0014] In the above description, as a further solution, both side walls of the chassis are side plates. A number of heat dissipation through holes are provided in the middle of the side plates. The heat dissipation through holes are connected in communication with the inside of the chassis. The air circulation inside the chassis can be improved through the heat dissipation through holes, providing an effective heat dissipation environment for the work of the copper wire twisting and anti-winding device.

[0015] In the above description, as a further solution, a handle is provided on the top of the chassis.

[0016] The beneficial effects produced by the present invention are as follows:

[0017] A tin-plated soft copper wire stranding device of the present application has clamping grooves on the inner side walls of both the first clamping finger and the second clamping finger. One end of the clamping groove on the inner side wall of the first clamping finger is provided with a limiting convex block protruding outward. A clearance fit can be carried out between the limiting convex block and the clamping groove on the inner side wall of the second clamping finger. The first clamping finger and the second clamping finger are driven by a cylinder slide to move relative to each other, so that the two clamping grooves approach each other, and thus effectively clamp the copper wire through the limiting convex block inside the clamping groove. Closing baffles are provided on both the top end face and the bottom end face of the second clamping finger. One side of the closing baffle extends towards the clamping groove, and the closing baffle can cover the upper part between the first clamping finger and the second clamping finger. When the closing baffle covers the inner side wall of the first clamping finger, a sealed isolation cavity can be formed, making it difficult for the copper wire to be exposed outside the finger cylinder, avoiding the copper wire being easily wound inside the rotary drive assembly of the copper wire stranding device, preventing the copper wire stranding device from easily malfunctioning, and improving the qualified rate of tin-plated soft copper wire stranding.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] For the convenience of those skilled in the art, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figures 1-6 , and a copper wire stranding anti - winding device implemented specifically includes a chassis 1, a finger cylinder 5, and a driving member for driving the rotation of the finger cylinder 5. Both side walls of the chassis 1 are side plates 2. A plurality of heat dissipation through - holes 9 are opened in the middle of the side plates 2. The heat dissipation through - holes 9 are in communication with the inside of the chassis 1. Through the heat dissipation through - holes 9, the air circulation inside the chassis 1 can be improved, providing an effective heat dissipation environment for the operation of the copper wire stranding anti - winding device. A handle 7 is provided on the top of the chassis 1.

[0027] A power interface 8 for providing driving power is provided on the back of the chassis 1. A start switch 10 for controlling the driving member and the control panel 3 is provided on the back of the chassis 1. A control panel 3 for controlling the finger cylinder 5 and the driving member is also provided on the front end face of the chassis 1. The control panel 3 is electrically connected to the driving member. By controlling the working sequence of the driving member and the finger cylinder 5 through the control panel 3, the finger cylinder 5 and the driving member can cooperate with each other to complete the automated copper wire stranding process.

[0028] The finger cylinder 5 is composed of a cylinder body 501, a cylinder slide 506, and a clamping assembly. The clamping assembly includes a first finger 507 and a second finger 508. Clamping grooves 5011 are opened on the inner side walls of the first finger 507 and the second finger 508. A limiting convex block 509 protruding outward is provided at one end of the clamping groove 5011 on the inner side wall of the first finger 507. A clearance fit can be achieved between the limiting convex block 509 and the clamping groove 5011 on the inner side wall of the second finger 508. Closing baffles 5010 are provided on the top and bottom end faces of the second finger 508. One side of the closing baffle 5010 extends towards the clamping groove 5011, and the closing baffle 5010 can cover the upper part between the first finger 507 and the second finger 508.

[0029] The inner wall of the clamping groove 5011 is of an arc - shaped structure. The surface of the limiting convex block 509 in contact with the clamping groove 5011 is an arc - shaped structure matching the inner wall of the clamping groove 5011. By driving the first finger 507 and the second finger 508 to move relative to each other through the cylinder slide 506, the two clamping grooves 5011 approach each other, and then the copper wire is clamped inside the clamping groove 5011 through the limiting convex block 509.

[0030] The middle of the closing baffle 5010 is of an upward - protruding arc - shaped structure. Due to the arc - shaped structure of the closing baffle 5010, when the closing baffle 5010 covers the inner side wall of the first finger 507, a sealed isolation cavity can be formed, making it difficult for the copper wire to be exposed outside the finger cylinder 5.

[0031] On the front end face of the cylinder block 501, two chutes 505 for installing the cylinder slides 506 are provided. The cylinder slides 506 are respectively slidably connected to the inside of the chutes 505. One ends of the first finger 507 and the second finger 508 are respectively fixedly connected to the cylinder slides 506. Through the chutes 505 provided on the front end face of the cylinder block 501, the cylinder slides 506 can slide along the inside of the chutes 505, making the docking and clamping between the first finger 507 and the second finger 508 more precise.

[0032] The bottom of the cylinder block 501 is a pipe base 503. The pipe base 503 is screwed and fixed to the driving member through the fixing bolts 504. An air inlet nozzle 502 for connecting to an external air supply component is provided on one side of the cylinder block 501. The air inlet nozzle 502 is connected in communication with the inside of the cylinder block 501. Air is supplied to the inside of the cylinder block 501 through the air inlet nozzle 502 on one side of the cylinder block 501, so that the cylinder slide 506 can move along the chute 505 by the push of the gas. At the same time, when the air pressure inside the cylinder block 501 is kept large enough, the copper wire can be clamped more firmly between the first finger 507 and the second finger 508.

[0033] The driving member is composed of a driving motor 6. A rotatable rotating base 4 is provided on the front end face of the driving motor 6. One end of the finger cylinder 5 away from the clamping component is fixedly connected to the rotating base 4. The driving motor 6 is fixedly connected inside the chassis 1. The rotating base 4 penetrates to the front end face of the chassis 1. The driving motor 6 drives the rotating base 4 to rotate around the center of the driving motor 6, so that the rotating base 4 can drive the finger cylinder 5 to rotate, enabling the copper wire clamped inside the finger cylinder 5 to be twisted by the driving motor 6.

[0034] The working principle is as follows: Place the copper wire between the first finger 507 and the second finger 508. At the same time, supply air to the inside of the cylinder block 501 through the air inlet nozzle 502, so that the cylinder slide 506 can move along the chute 505 by the push of the gas. The first finger 507 and the second finger 508 are respectively attached to each other through the cylinder slide 506. When the closing baffle 5010 covers the inner side wall of the first finger 507, the exposed copper wire can be wrapped in the isolation cavity formed by the closing baffle 5010, making it difficult for the copper wire to be exposed outside the finger cylinder 5. At the same time, the copper wire is clamped inside the clamping groove 5011 through the limiting protrusion 509. Then, start the driving motor 6. The driving motor 6 drives the rotating base 4 to rotate around the center of the driving motor 6, so that the rotating base 4 can drive the finger cylinder 5 to rotate, enabling the copper wire clamped inside the finger cylinder 5 to be twisted by the driving motor 6.

[0035] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention is disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content as equivalent embodiments of equivalent changes, but as long as it does not depart from the content of the technical solution of the present invention, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical means of the present invention all fall within the scope of the technical solution of the present invention.
