Description

Technical Field:

[0001] The utility model relates to the technical field of semi-finished wire processing, and particularly refers to a hot stripping device that can strip the outer sheath of a wire without damaging the wire core. Background Art:

[0002] Wires are essential components for communication, transmission, and power supply. Generally, the outer surface of a wire is covered with an insulating layer (outer sheath) made of a polymer material to isolate the metal wire inside the wire from the external environment, thereby ensuring the stable transmission of signals in the wire. When the wire is connected to an electrical device or an electronic component, a certain length of the insulating layer must be stripped off at both ends of the wire to expose the metal wire inside the wire for electrical connection. Thus, various peeling tools such as peeling knives, pliers, and peeling machines have emerged to strip the insulating layer of the wire.

[0003] With the high-speed development requirements of semi-finished wire processing involving headphone wires, data cables, VR headband wires, neck-hanging wires, in-ear headphone internal wires, automotive wires, etc., the requirements for existing processing technologies are getting higher and higher. Currently, most peeling tools on the market are prone to causing damage to the core wire when stripping the outer sheath of the wire, exposing the copper wire inside, which poses a risk of wire short circuit. For example, the utility model patent application with the patent publication number CN205828867U discloses a foot-operated wire peeling device, which includes: a frame body, the frame body includes a wire stripping platform, a wire stripping pliers is provided on the wire stripping platform, one clamping arm of the wire stripping pliers is fixed to the wire stripping platform, a driving connecting rod is arranged on the other clamping arm of the wire stripping pliers, a driving frame hinged to the bottom of the frame body and connected to the driving connecting rod to control the two clamping arms to approach or separate is provided on the driving frame, a foot pedal is provided on the driving frame, and a return spring is provided on the driving frame. The working efficiency of the foot-operated method is higher than that of a manual wire stripping pliers.

[0004] However, the above foot-operated wire peeling device has the following deficiencies:

[0005] 1. In this technical solution, the foot pedal drives the driving frame to rotate up and down, drives the clamping arm to move, and then controls the wire stripping pliers to open and close to achieve wire stripping. However, no buffer mechanism is provided, resulting in the wire stripping pliers being prone to excessive downward cutting when closing, damaging the core wire, causing the core wire to break and exposing the copper wire inside. A buffer mechanism should be added to protect the wire.

[0006] 2. In this technical solution, the foot-operated method is used instead of the traditional manual wire stripping pliers. Although the efficiency is higher than that of the manual wire stripping, it is still a cold cut and does not achieve hot stripping of the outer sheath. The efficiency needs to be further improved. In addition, the cut produced by the cold cut is generally not regular enough, and it is

[0007] difficult to meet the requirements for products with high processing technology requirements.

[0008] In view of this, the present inventor proposes the following technical solutions. Content of the utility model:

[0028] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0029] As shown in Figures 1 to 7 a wire outer sheath thermal stripping and anti - skinning device, which includes: a base 1, and further includes a support base 3 arranged on the base 1, a workbench 2 arranged on the base 1 and used for placing the wire, a lifting frame 4 arranged on the support base 3 in a slidable and liftable manner and one end of which extends above the workbench 2, a driving device 5 installed on one side of the support base 3 and capable of driving the lifting frame 4 to lift and lower, a first thermal stripping member 21 arranged on the workbench 2 and used for thermally stripping the wire, a second thermal stripping member 42 arranged on the lifting frame 4 and used for cooperating with the first thermal stripping member 21 to thermally strip the wire, and a buffer mechanism 6 arranged between the lifting frame 4 and the second thermal stripping member 42 and used for preventing the second thermal stripping member 42 from pressing down excessively.

[0030] Since the second hot stripping member 42 needs to be pressed down for cutting in the present utility model, without the buffer mechanism 6, in order to cut in place, the second hot stripping member 42 and the first hot stripping member 21 will be forced into hard contact, which not only easily damages the core wire but also easily causes damage to the blade. In the present utility model, the buffer mechanism 6 can prevent the second hot stripping member 42 from being pressed down excessively during cutting, effectively avoiding damage to the core wire. Specifically, the buffer mechanism 6 includes a plug shaft 61 that penetrates through one end of the lifting frame 4 and extends downward, a buffer seat 62 fixed to the lower end of the plug shaft 61, and a buffer spring 63 sleeved on the plug shaft 61 and used to push the buffer seat 62 downward. Four through holes 41 for limiting the plug shaft 61 are formed on the lifting frame 4. Correspondingly, the number of the plug shafts 61 is four, and the number of the buffer springs 63 is also four. A convex portion 610 for axially limiting the plug shaft 61 is formed at the end of the plug shaft 61. When the second hot stripping member 42 abuts downward against the wire and the first hot stripping member 21, the second hot stripping member 42 will be subjected to a reaction force and drive the buffer seat 62 to move upward slowly, thereby compressing the buffer spring 63. At this time, since the plug shaft 61 and the buffer seat 62 are fixed, the upper end of the plug shaft 61 will extend upward out of the through hole to achieve the buffering effect, so that the second hot stripping member 42 can cut sufficiently without damaging the core wire.

[0031] The first hot stripping member 21 includes a first hot stripping base 201 disposed on the workbench 2 and capable of generating high temperature, and a first blade 212 detachably disposed on one side of the first hot stripping base 201 and used for hot cutting the wire. Among them, a first wire 211 is connected between the first hot stripping base 201 and the support base 3, and a first stepped groove 213 is formed at the upper end of the first blade 212. The second hot stripping member 42 includes a second hot stripping base 420 disposed on the workbench 2 and capable of generating high temperature, and a second blade 422 detachably disposed on one side of the second hot stripping base 420 and used for hot cutting the wire. Among them, a second wire 421 is connected between the second hot stripping base 420 and the support base 3, and a second stepped groove 423 that is matched and limited with the first stepped groove 213 to prevent damage to the wire is formed at the lower end of the second blade 422. In this embodiment, the cutting edge of the first blade 212 is V-shaped, and correspondingly, the cutting edge of the second blade 422 is inverted V-shaped. And the first blade 212 and the second blade 422 can be replaced according to actual needs for different wires.

[0032] In this embodiment, an installation plate 31 is provided on the support base 3, and a slide rail 32 is installed on the installation plate 31. Correspondingly, a slider 44 is provided on the lifting frame 4; on the upper end surface of the installation plate 31, a fixed plate 33 is provided. One end of the fixed plate 33 is provided with a transmission connecting rod 7 that is driven by a driving device 5 to expand and contract and drive the lifting frame 4 to lift. On the basis of not changing the essence of the present utility model, according to actual needs, the slide rail 32 and the slider 44 can be replaced with lifting structures such as a lead screw structure and a chain drive structure.

[0033] A protrusion 34 is formed on the surface of the installation plate 31 close to the support base 3. Correspondingly, a limit groove 35 that matches the protrusion 34 and is used for horizontally limiting the installation plate 31 is formed on the support base 3, so that the installation plate 31 is arranged on the support base 3 in a manner of adjustable height; a strip-shaped groove 36 is also formed on the installation plate 31, and the slide rail 32 is fixedly installed in the strip-shaped groove 36.

[0034] The lifting frame 4 extends a transmission end 45 downward to the transmission connecting rod 7. A connecting groove 46 is formed on the transmission end 45, and the cross-sectional shape of the connecting groove 46 is in an inverted T shape or a cross shape; a transmission nut 47 is fixed at the lower end of the transmission connecting rod 7, and the transmission nut 47 is placed in the connecting groove 46 to drive the lifting frame 4 to lift. In addition, the lifting frame 4 extends an upper pressing end 48 upward to the workbench 2. The top view shape of the upper pressing end 48 is in a T shape or an inverted T shape, and the four through holes 41 are all formed on the upper pressing end 48.

[0035] See Figures 1 to 3 As shown, in this embodiment, the wire is fixed by the second positioning part 620 that opens and closes up and down to prevent the wire from shaking, thereby reducing the operation difficulty of the operator. Specifically, a first positioning part 210 for placing the wire is provided at one end of the workbench 2, and a second positioning part 620 that matches the first positioning part 210 is provided on the buffer mechanism 6. The second positioning part 620 synchronously lifts with the buffer mechanism 6 to press against the first positioning part 210 and position the wire; a third positioning part 23 for axially limiting the wire is provided at the other end of the workbench 2. Correspondingly, a fourth positioning part 64 corresponding to the third positioning part 23 is provided on the lower end surface of the buffer mechanism 6. Among them, a wire feeding groove 230 is also formed on the upper end surface of the first positioning part 210. Specifically, when the driving device 5 drives the lifting frame 4 to rise, the second positioning part 620 rises synchronously. The operator manually places the wire in the wire feeding groove 230 on the first positioning part 210. Further, the driving device 5 drives the lifting frame 4 to press down, and the second positioning part 620 abuts against the upper end surface of the first positioning part 210 to prevent the wire from accidentally moving; at this time, the operator rotates the wire clockwise by 360°. The first hot stripping part 21 and the second hot stripping part 42 will quickly burn off the outer sheath of the wire, and finally pull out the wire, that is, the hot stripping is completed; it effectively reduces the working intensity of the operator and helps to improve the work efficiency.

[0036] A power control box 8 is installed on one side of the support base 3. A drive device switch 81 for controlling the drive device 5 is provided in the power control box 8. A time relay 82 for controlling the lifting time of the lifting frame 4 is provided in the power control box 8. A temperature control sensor 83 for inductively controlling the temperatures of the first hot stripping member 21 and the second hot stripping member 42 is further provided in the power control box 8.

[0037] A protective cover 9 for blocking foreign objects and preventing pinching is further sleeved outside the lifting frame 4.

[0038] In summary, in the present utility model, the drive device 5 drives the lifting frame 4 to perform lifting and cutting through the transmission connecting rod 7, and the first hot stripping member 21 and the second hot stripping member 42 have a hot cutting function. After the wire is placed, the operator only needs to manually rotate the wire one circle, and the first hot stripping member 21 and the second hot stripping member 42 will quickly burn off the fiber outer sheath, avoiding cold cutting, effectively improving the cutting efficiency and the regularity of the cut. In addition, different from the existing structure, a buffer mechanism 6 is further provided between the lifting frame 4 and the second hot stripping member 42 in the present utility model, so that the second hot stripping member 42 will not be pressed down excessively during cutting, effectively avoiding damage to the core wire, and realizing the removal of the outer sheath without damaging the core wire.
