Abstract
Description
Technical Field
[0001] The patent of this invention relates to the technical field of wire harness welding, and specifically, to a method for stripping the core wire and sheath of a cable. Background Art
[0002] The cable core is the core part of the cable, responsible for the transmission of current or signals, while the sheath protects the core, eliminating interference from the external environment and ensuring the effective transmission of current or signals.
[0003] The sheath is an insulator. When the core wires need to be connected, stripping off a section of the sheath can expose the inner core wire, thereby ensuring a tight connection between the wires and ensuring smooth transmission of current.
[0004] In the prior art, traditional stripping methods often rely on manual operation, which is not only inefficient, but also difficult to ensure that the position and depth of each stripping are consistent. It is easily affected by the operator's skill level and fatigue. Due to the limitations of manual operation, the stripping speed is often slow. Especially when a large number of cables need to be stripped, this inefficiency problem is more prominent.
[0005] Additionally, operators may be exposed to safety risks when using stripping tools, especially when stripping at high speeds or for long periods of time. Summary of the invention
[0006] The purpose of the present invention is to provide a method for stripping a cable core wire and a sheath, aiming to solve the problem of low efficiency of manually stripping the sheath in the prior art.
[0007] The present invention is achieved by comprising the following steps:
[0008] 1) moving the cladding and the core wire relative to each other so that the cladding bulges to form a fold section;
[0009] 2) puncturing the pleated section to form an initial opening, wherein the end of the core wire has an end section, and the end section has an exposed section exposed in the initial opening;
[0010] 3) expanding the initial opening so that the size of the initial opening reaches a set size;
[0011] 4) Clamping the exposed section and rotating it at a set angle to peel the end section off from the cladding.
[0012] Further, the step 4) is repeated until the end segment is completely peeled off from the cladding.
[0013] Furthermore, in the step 1), the cable is clamped respectively by two movable clamps arranged at intervals, and the two movable clamps move toward each other, and the cladding moves relative to the core wire, so that the cladding bulges to form the folded section.
[0014] Furthermore, in the step 2), a thorn bar is provided above the pleat segment, and the bottom of the thorn bar has an inverted and conical thorn head, which moves toward the pleat segment and punctures the pleat segment to form the initial opening in the pleat segment.
[0015] Furthermore, in the step 3), a transverse spreader is used to pass through the initial opening to spread the initial opening apart so that the size of the initial opening reaches a set size.
[0016] Furthermore, in step 3), the lateral spreader includes two lateral support heads that move toward or away from each other. After the two lateral support heads are inserted into the initial opening, the two lateral support heads move away from each other to expand the initial opening so that the size of the initial opening reaches a set size.
[0017] Furthermore, in the step 3), the two transverse support heads are arranged along the axial direction of the cable. After the two transverse support heads are inserted into the initial opening, the two transverse support heads move away from each other along the axial direction of the cable to expand the axial dimension of the initial opening.
[0018] Furthermore, in the step 3), after the size of the initial opening is expanded, a radial expander is inserted into the initial opening, and the radial expander includes two radial support heads that move toward or away from each other. After the two radial support heads are inserted into the initial opening, they move away from each other in the radial direction of the cable to expand the radial size of the cable.
[0019] Furthermore, in the step 3), when the radial size of the initial opening is expanded, the two radial supports move toward each other to clamp and fix the end of the exposed section; in the step 4), after the end of the exposed section is clamped and fixed, the exposed section is clamped by a rotating chuck arranged in a rotating manner, and the rotating chuck is rotated at a set angle to peel the end section off from the cladding.
[0020] Furthermore, in the step 2), the bottom of the thorn head has a pointed tip, the outer periphery of the thorn head forms a conical surface, the outer periphery of the conical surface is provided with a plurality of inclined spring pieces, and the plurality of inclined spring pieces are arranged around the circumference of the conical surface at intervals; the lower end of the inclined spring piece is butt-jointed with the conical surface, and the upper end of the inclined paving is arranged away from the conical surface; along the direction from bottom to top of the inclined spring piece, the inclined spring piece is arranged away from the conical surface and is inclined, and there is a deformation interval between the inclined spring piece and the conical surface;
[0021] In the step 2), when the tip of the piercing head passes through the cladding and the piercing head moves downward, the plurality of inclined spring pieces are inserted between the claddings, and the plurality of inclined spring pieces are elastically deformed inwardly under pressure, and reversely press the cladding to open it, so as to form the initial opening;
[0022] When the thorn head moves upward and exits the cladding, the plurality of inclined spring pieces are separated from the pressure on the cladding and swing outward to elastically restore the deformation.
[0023] Compared with the prior art, the cable core wire and cladding stripping method provided by the present invention has the following advantages:
[0024] First of all, by moving the cladding and the core wire relative to each other, the damage to the cable can be reduced. The formed wrinkled section provides a clear position for subsequent stripping, creating favorable conditions for the subsequent stripping work.
[0025] Secondly, compared with manual cutting, the operation of puncturing the pleated segment can more accurately control the peeling position and reduce material waste. By expanding the initial opening, unnecessary damage to the core wire during the peeling process can be avoided, while also ensuring the thoroughness of the peeling.
[0026] Finally, the exposed section is clamped and rotated at a set angle to achieve the stripping of the end section from the sheath. This step utilizes the mechanical action of rotation to improve the efficiency and accuracy of stripping, while also reducing the complexity of manual operation, thereby significantly improving the efficiency of stripping the cable core and sheath. The quality and efficiency of cable processing are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Reference Figure 1-4 The figure shows a preferred embodiment of the present invention.
[0036] The method for stripping the cable core and the cable sheath comprises the following steps:
[0037] 1) The cladding 100 and the core wire 400400 are relatively moved so that the cladding 100 bulges to form a fold section 103;
[0038] 2) Puncture the folded section 103 to form an initial opening 102, the end of the core wire 400400 has an end section 401, and the end section 401 has an exposed section 402 exposed in the initial opening 102;
[0039] 3) expanding the initial opening 102 so that the size of the initial opening 102 reaches a set size;
[0040] 4) Clamp the exposed section 402 and rotate it to a set angle to peel the end section 401 off the cladding 100.
[0041] The cable core and sheath stripping method provided above has the following advantages:
[0042] Firstly, by making the cladding 100 and the core wires 400400 move relative to each other, the damage to the cable can be reduced, and the formed wrinkled section 103 provides a clear position for stripping, thus creating favorable conditions for subsequent stripping work.
[0043] Secondly, compared with manual cutting, the operation of puncturing the pleated section 103 can more accurately control the peeling position and reduce material waste. By expanding the initial opening 102, unnecessary damage to the core wire 400400 during the peeling process can be avoided, while also ensuring the thoroughness of the peeling.
[0044] Finally, the exposed section 402 is clamped and rotated at a set angle to realize the stripping of the end section 401 from the cladding 100. This step utilizes the mechanical action of rotation to improve the efficiency and accuracy of stripping, while also reducing the complexity of manual operation, thereby significantly improving the efficiency of stripping the cable core wires 400400 from the cladding 100, thereby improving the quality and efficiency of cable processing.
[0045] In this embodiment, step 4) is repeated until the end segment 401 is completely stripped from the cladding 100. This ensures that the end segment 401 can be completely stripped from the cladding 100, thereby improving the integrity and reliability of the stripping, thereby ensuring the quality and consistency of cable processing.
[0046] In this embodiment, in step 1), two movable chucks 203 arranged at intervals are used to clamp the cable respectively, and the two movable chucks 203 move toward each other, and the cladding 100 moves relative to the core wire 400400, so that the cladding 100 bulges to form a corrugated section 103. By precisely controlling the relative movement of the chucks, the corrugated section 103 is effectively formed, which provides a clear position for subsequent stripping and reduces damage to the cable.
[0047] In this embodiment, in step 2), a barb is provided above the pleated segment 103, and the bottom of the barb has an inverted and conical thorn head 300, which moves toward the pleated segment 103 and punctures the pleated segment 103 to form an initial opening 102 in the pleated segment 103. In this way, the initial opening 102 can be formed quickly, thereby improving the efficiency and accuracy of peeling.
[0048] In this embodiment, in step 3), a transverse stretcher is used to pass through the initial opening 102 to stretch the initial opening 102 apart so that the size of the initial opening 102 reaches a set size. The transverse stretcher is used to ensure that the size of the initial opening 102 meets the requirements, thereby providing a stable operating space for subsequent peeling work.
[0049] In this embodiment, in step 3), the lateral stretcher includes two lateral support heads that move toward or away from each other. After the two lateral support heads are inserted into the initial opening 102, the two lateral support heads move away from each other to expand the initial opening 102 so that the size of the initial opening 102 reaches the set size, thereby improving the stability and reliability of the peeling process.
[0050] In this embodiment, in step 3), the two lateral supports are arranged along the axial direction of the cable. After the two lateral supports are inserted into the initial opening 102, the two lateral supports move away from each other along the axial direction of the cable to expand the axial size of the initial opening 102. By axially expanding, the initial opening 102 is effectively expanded, providing a possible operating space for subsequent radial peeling.
[0051] In this embodiment, in step 3), after the size of the initial opening 102 is expanded, a radial expander 200 is inserted into the initial opening 102. The radial expander 200 includes two radial support heads 201 that move toward or away from each other. After the two radial support heads 201 are inserted into the initial opening 102, they move away from each other along the radial direction of the cable to expand the radial size of the cable. Through radial expansion, the initial opening 102 is further expanded, providing more operating space for the peeling of the end segment 401, making the peeling process smoother.
[0052] In this embodiment, in step 3), when the radial size of the initial opening 102 is expanded, the two radial support heads 201 move toward each other to clamp and fix the end of the exposed section 402; in step 4), after the end of the exposed section 402 is clamped and fixed, the exposed section 402 is clamped by a rotating chuck 202 that is rotatably arranged, and the rotating chuck 202 is rotated to a set angle so that the end section 401 is peeled off from the cladding 100.
[0053] The end of the exposed section 402 will not be displaced after being clamped, which not only realizes efficient stripping of the end section 401, but also controls the stripping position and length of the cladding 100, thereby reducing the stripping error caused by manual operation.
[0054] In this embodiment, in step 2), the bottom of the thorn head 300 has a tip 301, and the outer periphery of the thorn head 300 is formed with a conical surface 302. The outer periphery of the conical surface 302 is provided with a plurality of inclined spring pieces 303, and the plurality of inclined spring pieces 303 are arranged around the conical surface 302 at intervals in the circumferential direction; the lower end of the inclined spring piece 303 is docked on the conical surface 302, and the upper end of the inclined paving is arranged away from the conical surface 302; along the direction from bottom to top of the inclined spring piece 303, the inclined spring piece 303 is arranged away from the conical surface 302 and is inclined, and there is a deformation interval between the inclined spring piece 303 and the conical surface 302;
[0055] In step 2), when the tip 301 of the piercing head 300 passes through the cladding 100 and the piercing head 300 moves downward, the plurality of inclined spring pieces 303 are inserted between the cladding 100, and the plurality of inclined spring pieces 303 are elastically deformed inwardly under pressure, and reversely press the cladding 100 to open, so as to form an initial opening 102;
[0056] When the spike head 300 moves upward and exits the cladding 100, the multiple inclined spring pieces 303 are separated from the pressure on the cladding 100 and swing outward to elastically restore the deformation. The outward elastic force of the inclined spring pieces 303 can be used to quickly and evenly open the cladding 100, so that the initial opening 102 can maintain a certain opening state after it is formed. After the inclined spring pieces 303 are separated from the pressure, they can restore the deformation so that they can be recycled, reducing loss. At the same time, they can also maintain correct operation for a long time, thereby effectively solving the problem of low efficiency in manually stripping the cladding 100.
[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
