Description

Technical Field

[0001] This invention belongs to the field of wire harness processing equipment technology, and particularly relates to a wire stripping mold. Background Technology

[0002] In the field of wire processing, wire stripping is a crucial and fundamental process, and its quality and efficiency directly affect the results of subsequent wire connection, welding, and other processes. Currently, the most common wire stripping methods on the market are mainly divided into two categories: manual stripping and mechanical stripping.

[0003] Manual wire stripping relies on operators using tools such as wire strippers to manually peel off the insulation of electrical wires. While this method is flexible and suitable for processing small batches of various types of wires, it has significant drawbacks. Firstly, manual operation is extremely inefficient, making it difficult to meet the demands of large-scale production. This is especially true in industries with high wire demand, such as power engineering and home appliance manufacturing, where manual stripping often becomes a bottleneck in the production process. Secondly, the quality of manual stripping depends heavily on the operator's experience and skill, easily leading to incomplete insulation removal and damage to the wire core, affecting the electrical performance and lifespan of the wire, while also increasing labor costs.

[0004] Mechanical wire stripping equipment is divided into two categories: fully automatic and semi-automatic. Although fully automatic wire stripping equipment is highly efficient and provides stable stripping quality, it has a complex structure, large size, and extremely high manufacturing and maintenance costs. For small and medium-sized enterprises or scenarios with small processing volumes, the investment cost is too high, resulting in low cost-effectiveness. Furthermore, the equipment is difficult to adjust and is not suitable for the rapid switching of processing various specifications of wires.

[0005] Semi-automatic wire stripping equipment typically requires the use of crimping machines and other similar equipment, but existing semi-automatic wire stripping molds have several shortcomings. Some stripping equipment employs a multi-pressure structure, which is complex, cumbersome to operate, and difficult to adjust the stripping depth, making it unsuitable for wires with different insulation thicknesses. Other equipment lacks an effective wire length positioning mechanism, failing to accurately control the stripping length and resulting in inconsistent wire specifications after processing, affecting subsequent assembly. Still others have poorly designed cutting components, only capable of stripping one end of the wire, failing to meet the need for stripping the middle, thus limiting their functionality and applicability. In summary, current wire stripping technology suffers from low efficiency, high cost, poor adaptability, and limited functionality. There is an urgent need for a wire stripping mold that can balance efficiency, cost, adaptability, and multi-functionality to meet the needs of different production scales and processing requirements. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a wire stripping mold that can significantly improve stripping efficiency and reduce usage costs while meeting the requirements of manual batch operations. It also features adjustable stripping length, easily adjustable stripping depth, and the ability to strip stripping from one end or in the middle, adapting to the processing needs of various wire specifications and solving the problems in the prior art.

[0015] Preferably, the adjusting component is a wedge structure, and the limiting component is a screw structure. The screw structure passes through the slider body and extends into the groove of the adjusting component. By adjusting the insertion depth of the screw structure, the range of motion of the adjusting component can be limited, thereby adjusting the relative position of the slider assembly and the cutting assembly, and realizing the adjustment of the peeling depth.

[0016] Preferably, the cutting tool of the cutting tool assembly is made of wear-resistant metal material, and the shape of the cutting edge can be adapted to the characteristics of the wire insulation. An adjustment structure is provided between the support and the cutting tool assembly, which can adjust the installation height or angle of the cutting tool to adapt to the insulation cutting requirements of wires of different specifications.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention provides a wire stripping mold that, through the coordinated action of the main component, the slider component, and the cutting component, achieves semi-automatic stripping operation with the help of the power provided by the crimping machine. Compared with traditional manual stripping, the efficiency is increased by at least 3 times, which can meet the needs of large-scale mass production and effectively solve the stripping bottleneck problem in the production process.

[0023] The mold has a simple overall structure, is made of conventional materials, and has low manufacturing costs. Furthermore, most of the mold's components are detachable, facilitating maintenance and replacement of damaged parts, thus reducing maintenance costs. Compared to fully automatic peeling equipment, this invention offers lower purchase and operating costs, making it extremely cost-effective and particularly suitable for small and medium-sized enterprises.

[0024] The wire length positioning component can move along the wire positioning base, and with the scale on the wire positioning base, it can meet the needs of different stripping lengths from 5 to 100 mm. On the other hand, by adjusting the positioning screw, the position of the lower wedge can be changed, thereby adjusting the relative position between the slider component and the cutting component, realizing flexible adjustment of the stripping depth. It can adapt to the stripping needs of wires with different specifications and insulation thicknesses of 0.5-5 mm, and is suitable for processing various types of wires.

[0025] The cutting assembly includes an upper stripper, a lower stripper, and two center cutters. The upper and lower stripper can strip the insulation from one end of the wire, while the two center cutters can cut the insulation from the middle of the wire. Together with the upper and lower stripper, the insulation can be stripped from the middle of the wire, solving the problem of some existing molds only being able to strip insulation from one end and expanding the applicability of the mold.

[0026] The left and right pressure plates guide the slider assembly, ensuring that the slider assembly drives the upper stripper, upper pad, and middle cutter to move stably downwards, guaranteeing accurate cutting positions of the upper stripper, lower stripper, and middle cutter on the insulation. At the same time, the wire length positioning component can accurately position the end of the wire, ensuring consistent stripping length each time. This effectively avoids problems such as incomplete insulation stripping, damage to the core wire, and inconsistent stripping lengths that occur with manual stripping, resulting in stable and reliable stripping quality and improving the pass rate of wire processing.

[0040] Example:

[0041] refer to Figure 1As shown, a wire stripping mold includes a main body assembly 1 for providing basic support, a hanging head assembly 3 for transmitting power, a slider assembly 2 that moves along the main body assembly 1, a cutting assembly 4 for cutting wire insulation, and a wire length positioning assembly 5 for positioning the stripping length of the wire. The hanging head assembly 3 is connected to the slider assembly 2 and drives the slider assembly 2 to reciprocate along the main body assembly 1. The cutting assembly 4 is correspondingly arranged with the slider assembly 2 and cuts the wire insulation as the slider assembly 2 moves. The wire length positioning assembly 5 cooperates with the cutting assembly 4 to position the length of the wire entering the cutting assembly 4, thereby controlling the stripping length.

[0042] refer to Figure 2-3 The main component 1 includes a main body 103, side pressure plates 101 for guiding and limiting the slider assembly 2, and a base plate 104 for supporting the mounting components. The side pressure plates 101 are disposed on the side of the main body 103 and slide in cooperation with the slider assembly 2. The base plate 104 is fixedly connected to the main body 103 and is used to install the cutting component 4 or the wire length positioning component 5. There are two side pressure plates 101, which are symmetrically or evenly distributed on the outside of the main body 103. The side pressure plates 101 are detachably connected to the main body 103, and the base plate 104 is connected to the main body 103 by screws, pins, or other positioning connectors. The base plate 104 is provided with adjustment holes or positioning grooves for adjusting the installation position of the cutting component 4. The main component serves as the basic support structure of the mold and includes a left pressure plate, a right pressure plate, the main body, and the base plate. The side pressure plate 101 includes a left pressure plate and a right pressure plate. The left pressure plate and the right pressure plate are symmetrically fixed on both sides of the main body by screws. They are used to guide and limit the movement of the slider assembly and prevent the slider assembly from shifting during the up and down movement. The base plate is fixedly connected to the bottom of the main body by screws and pins. The pins can ensure the positioning accuracy between the base plate and the main body, avoid the base plate from shifting due to long-term use, and ensure the stability of the overall structure of the mold.

[0043] refer to Figure 4-5 The slider assembly 2 includes a slider 202 body, an adjusting member 201 for assisting in adjusting the peeling depth, and a limiting member for limiting the range of motion of the adjusting member 201. The adjusting member 201 is disposed in the inner groove of the slider 202 body and can reciprocate along the groove. The limiting member passes through the slider 202 body and cooperates with the adjusting member 201 to limit the travel of the adjusting member 201. The slider 202 body is slidably engaged with the side pressure plate 101 of the main body assembly 1, and the slider 202 body is provided with an installation structure for installing some parts of the cutting assembly 4. The adjusting member 201 is a wedge structure, and the limiting member is a screw structure. The screw structure passes through the slider 202 body and extends into the groove of the adjusting member 201. By adjusting the insertion depth of the screw structure, the range of motion of the adjusting member 201 can be limited, thereby adjusting the relative position of the slider assembly 2 and the cutting assembly 4 to achieve the adjustment of the peeling depth.

[0044] The slider assembly specifically includes a lower wedge, a slider, and a positioning screw. The slider is a block-shaped structure with an internal groove, and its outer side slides in engagement with the left and right pressure plates in the main assembly, allowing it to move up and down along the guide direction of the left and right pressure plates. The lower wedge is set in the groove of the slider, with its outer side sliding in contact with the groove wall. The positioning screw passes through the side wall of the slider and extends into the groove on the lower wedge, with its end sliding in engagement with the groove wall. This structural design allows the lower wedge to move up and down within the groove of the slider, while the positioning screw limits the maximum vertical movement of the lower wedge, preventing it from falling out of the groove of the slider. When the lower wedge is subjected to external force, its vertical movement adjusts the relative position between the slider assembly and the cutting assembly, thereby assisting in adjusting the peeling depth.

[0045] The mounting head assembly 3 adopts a structure adapted to external driving equipment, including a crimping machine; the mounting head assembly 3 and the slider assembly 2 are detachably connected, and the mounting head assembly 3 is a mounting structure for realizing power transmission.

[0046] refer to Figure 6-7 The cutting assembly 4 includes a fixing block 401 for fixed installation, a first guide block 402 for lateral positioning of the wire, a cutting tool assembly for cutting the wire insulation, and a support for supporting the cutting tool assembly. The fixing block 401 is fixedly connected to the base plate 104 of the main assembly 1. The first guide block 402 and the support are respectively connected to the fixed base. The cutting tool assembly includes side cutting tools for cutting the insulation from both sides of the wire and a middle cutting tool for cutting the insulation from the middle of the wire. The side cutting tools include an upper cutting tool and a lower cutting tool respectively disposed on the upper and lower sides of the wire. The upper cutting tool is connected to the slider assembly 2 and moves with the slider assembly 2. The lower cutting tool is connected to the fixed base or the support. The middle cutting tool is respectively disposed corresponding to the upper cutting tool and the lower cutting tool to jointly realize the cutting of the wire insulation.

[0047] The fixing block 401 of the cutting component is fixed to the base plate of the standard mold. The first guide block 402, the lower stripper 403, and the lower pad block 404 are attached in a certain order and fixed to the fixing block 401 with screws. The upper stripper 405 and the upper pad block 406 are attached together in a certain order and fixed to the slide block of the standard mold frame with screws. The center cutter 407 is fixed to the upper pad block 406 and the lower pad block 404 with Allen head screws. The upper stripper 405 and the upper pad block 406 are fixed to the slide block assembly with screws and move by the up and down movement of the slide block. The center cutter 407 is installed in the lower pad block 404 and the upper pad block 406 respectively. After adjusting the height as needed, it is tightened with screws. As the slider moves down, the upper stripper 405, the upper pad 406, and the upper center cutter 407 move down and act on the wire insulation. The upper stripper 405 and the lower stripper 403 strip the outer sheath of the wire, and the two center cutters 407 cut the insulation in the middle of the wire.

[0048] The cutting assembly is the core component for stripping wires, including a fixing block, a wire-fixing block, a lower stripping blade, a hexagonal flat-end set screw, a lower pad, an upper stripping blade, an upper pad, and a center cutter. The fixing block is fixed to the base plate of the main component with screws, providing an installation base for other parts of the cutting component. The wire guide block, lower stripper, and lower pad block are attached in sequence from left to right and fixed to the top of the fixing block with screws. The wire guide block is used to position the wire laterally to ensure the wire is stable during stripping. The blade of the lower stripper faces the direction of wire entry and is used to peel the insulation from below the wire. The lower pad block is used to support the lower stripper and adjust its height. The upper stripper and upper pad block are attached together in sequence from top to bottom and fixed to the bottom of the slider assembly with screws. The upper stripper and lower stripper are symmetrically arranged vertically, with their blades facing the wire, and are used to peel the insulation from above the wire. The upper pad block is used to support the upper stripper and adjust its height. There are two center cutters, which are fixed to the inside of the upper and lower pad blocks with hexagonal set screws respectively. The blades of the center cutters face the axis of the wire, and the two center cutters are symmetrically arranged vertically. During the stripping process, the upper stripping blade, lower stripping blade, and middle cutting blade work together on the insulation of the wire. The upper and lower stripping blades cut the insulation from the top and bottom sides, while the two middle cutting blades cut the insulation from the middle of the wire, thus achieving stripping of the insulation from one end or the middle of the wire.

[0049] refer to Figure 8-9 The wire length positioning component 5 includes a fixed base 501 for supporting the positioning component, a second wire positioning block 502 for positioning the end of the wire, and fasteners for fixing the fixed base 501. The fixed base 501 is connected to the fixed block 401 of the cutting component 4 or the base plate 104 of the main component 1. The fixed base 501 is provided with a scale structure for marking the length. The second wire positioning block 502 is movably engaged with the fixed base 501 and can move along the extension direction of the scale structure. It is fixed at a designated position on the positioning base by the fasteners to adapt to different stripping length requirements.

[0050] The wire length positioning assembly includes a hexagon head screw, a wire guide block, and a wire guide holder. The wire guide holder is fixed to the fixing block of the cutting assembly by screws. The top of the wire guide holder has graduations that extend in the same direction as the wire feed, allowing operators to easily read and set the stripping length. The wire guide block is mounted on top of the wire guide holder by a hexagon head screw. The wire guide block can move left and right along the direction of the graduations on the wire guide holder. Operators can move the wire guide block to the corresponding graduation position according to the required stripping length and then fix it with the hexagon head screw. The wire guide block is used to position the end of the wire, ensuring consistent stripping length each time and meeting the stripping length requirements of different wire specifications.

[0051] The cutting tool assembly uses a wear-resistant metal material for its blades, and the blade shape can be adapted to the characteristics of the wire insulation. An adjustment structure is provided between the support and the cutting tool assembly to adjust the installation height or angle of the cutting tool to meet the cutting needs of insulation of wires of different specifications.

[0052] The scale range on the fixed base 501 can be set according to actual needs, and the scale accuracy is greater than 1mm; the positioning surface of the second wire fixing block 502 is set as a plane or an arc surface that matches the shape of the wire, so that the wire is positioned stably; the fasteners are set as screws, bolts or other connecting parts that can be detached and fixed.

[0053] The connection methods between the components include screw connection, pin connection, snap connection or other detachable connection methods, which facilitates the installation, maintenance and replacement of the components; the main structural components of the mold are made of metal materials, including steel, aluminum alloy or other high-strength wear-resistant metals.

[0054] The mold can be adapted to wires of different specifications. The insulation layer thickness of the wires ranges from 0.1 to 10 mm, and the stripping length ranges from 1 to 200 mm. By adjusting the wire length positioning component and the slider component, the stripping process of wires of different specifications can be realized.

[0055] As one possible implementation method, the mold assembly process is as follows: 1. Main body component assembly: First, place the main body on a horizontal workbench, take the left and right pressure plates, and fix them symmetrically on the left and right sides of the main body with M6×15 socket head cap screws. The tightening torque of the screws is controlled at 15-20 N·m to ensure that the left and right pressure plates are firmly connected to the main body and are parallel. Next, place the base plate at the bottom of the main body, align the positioning holes on the base plate with the positioning pin holes at the bottom of the main body, insert cylindrical pins with a diameter of 8 mm and a length of 20 mm for positioning, and then fix the base plate to the main body with M8×20 socket head cap screws. The tightening torque of the screws is controlled at 25-30 N·m to complete the assembly of the main body components. 2. Slider assembly assembly: Place the lower wedge into the slot of the slider, ensuring it can slide freely within the slot. Then, pass the positioning screw through the threaded hole on the side wall of the slider, allowing the end of the positioning screw to extend into the slot on the lower wedge. Adjust the insertion depth of the positioning screw to control the vertical movement distance of the lower wedge within the slot to 5-10mm. Finally, tighten the positioning screw to complete the slider assembly assembly. 3. Secure the mounting head assembly to the top of the slider assembly using an M5×12 socket head cap screw. Control the tightening torque of the screw to 10-15 N·m to ensure synchronous movement between the mounting head assembly and the slider assembly. 4. Assembly of Cutting Components: First, fix the fixing block to the base plate of the main component using M8×25 socket head cap screws, with a tightening torque of 25-30 N·m. Second, attach the guide block, lower stripper, and lower pad block in order from left to right, aligning the screw holes on all three. Then, fix them to the top of the fixing block using M6×12 socket head cap screws, with a tightening torque of 15-20 N·m. Adjust the position of the lower stripper so that its blade is aligned with the center line of the fixing block. Third, attach the upper stripper and upper pad block in order from top to bottom, aligning the screw holes on both. Align the nail holes and fix them to the bottom of the slider assembly with M6×12 socket head cap screws. Control the screw tightening torque to 15-20 N·m. Adjust the position of the upper stripper blade so that it is symmetrical with the lower stripper blade and the blades are aligned. Fourth step, put the two center-opening blades into the mounting holes on the inner side of the upper and lower pads respectively. Adjust the extension height of the center-opening blades according to the insulation layer thickness of the wire to be stripped so that the blades of the center-opening blades can just contact the insulation layer of the wire without damaging the core wire. Then fix the center-opening blades with socket head cap set screws. Control the tightening torque of the set screws to 8-12 N·m. The assembly of the cutting assembly is completed.5. Wire Length Positioning Component Assembly: Fix the wire positioning base to the fixing block of the cutting component using M6×15 socket head cap screws. Control the screw tightening torque to 15-20 N·m, ensuring the scale lines on the wire positioning base are aligned with the wire feed direction. Then, install the wire positioning block on top of the wire positioning base using socket head cap screws. According to the required stripping length, move the wire positioning block to the corresponding position along the scale lines of the wire positioning base, and tighten the socket head cap screws to complete the assembly of the wire length positioning component. 6. Overall Assembly: Place the assembled slider assembly and hanging head assembly between the left and right pressure plates of the main component, allowing the slider to slide against the left and right pressure plates to complete the overall assembly of the mold.

[0056] Taking a copper core wire with a stripping length of 20mm and an insulation layer thickness of 2mm as an example, the stripping process of the mold of this invention is as follows: 1. Parameter setting: According to the required stripping length of the wire (20mm), loosen the internal hexagonal head screw of the wire length positioning block in the wire length positioning assembly, move the wire positioning block to the 20mm scale position along the scale line on the wire positioning base, and then tighten the internal hexagonal head screw to complete the stripping length setting; according to the insulation layer thickness of the wire (2mm), loosen the positioning screw in the slider assembly, adjust the position of the lower wedge block in the slider groove, and thus change the relative distance between the slider assembly and the cutting assembly, so that the distance between the upper stripping blade and the lower stripping blade is just enough to cut into the insulation layer without damaging the core wire. After adjustment, tighten the positioning screw to complete the stripping depth setting. 2. Wire placement: Insert one end of the wire to be stripped between the wire positioning block of the cutting assembly and the upper and lower stripping blades, so that the end of the wire contacts the wire positioning block in the wire length positioning assembly to achieve wire positioning. 3. Power Drive: Connect the mold's hanging head assembly to the drive mechanism of the standard crimping machine. Start the crimping machine; the drive mechanism drives the hanging head assembly downwards, which in turn drives the slider assembly to slide downwards along the left and right pressure plates of the main body assembly. 4. Insulation Cutting: As the slider assembly slides downwards, it drives the fixed upper stripping blade, upper pad, and the center cutting blade within the upper pad to move downwards simultaneously. When it reaches a certain position, the upper and lower stripping blades work together to cut the insulation from the top and bottom of the wire. Simultaneously, the center cutting blades within the upper and lower pads work together to cut the insulation from the middle of the wire, forming three independent insulation sections (one at the wire end, one in the middle, and one remaining section). 5. Manual Removal: The crimping machine's drive mechanism drives the hanging head assembly and slider assembly upwards to reset. The operator manually peels the cut insulation from the wire end and middle, completing the wire stripping operation. Then, the stripped wire is removed, and the next wire to be stripped is placed in the slot. The above steps are repeated for batch stripping. When it is necessary to strip the insulation from the middle of an electrical wire, simply adjust the position of the wire in the cutting assembly so that the middle part of the wire to be stripped is located between the upper stripping blade, the lower stripping blade, and the middle cutting blade. No other parameters need to be adjusted. The stripping operation of the middle of the wire can be completed by following the above steps. The operation is simple and quick.

[0057] Adjustments for Different Wire Specifications: 1. Adjustment for Different Stripping Lengths: For wires with a stripping length of 10mm, simply loosen the hexagonal head screws on the wire guide block, move the wire guide block along the scale line of the wire guide base to the 10mm mark, and fix it. For wires with a stripping length of 50mm, similarly move the wire guide block to the 50mm mark and fix it. No other parts need to be adjusted, making it widely adaptable and easy to adjust. 2. Adjustment for Different Insulation Thicknesses: For wires with an insulation thickness of 1mm, loosen the positioning screws on the slider assembly, move the lower wedge upwards to reduce the distance between the slider assembly and the cutting assembly, allowing the upper and lower stripping blades to cut into the 1mm thick insulation layer. After adjustment, tighten the positioning screws. For wires with an insulation thickness of 4mm, move the lower wedge downwards to increase the distance between the slider assembly and the cutting assembly, ensuring that the upper and lower stripping blades can cut into the 4mm thick insulation layer without damaging the core wire. The adjustment process is simple and requires no blade replacement.

[0058] Specifically, the hanging head assembly uses a mature assembly, which is detachably connected to the slider assembly via screws. This hanging head assembly is compatible with the drive mechanism of a standard crimping machine, transmitting the power of the crimping machine to the slider assembly, causing the slider assembly to reciprocate up and down within the main body assembly, providing power for the peeling action. The detachable connection facilitates maintenance and replacement of the hanging head assembly. The hanging head assembly consists of three parts: the main body, the cable adjustment, and the core cable adjustment. The main body includes an adjustment seat (with a vertical through hole and a square groove), a cover plate, and a scale plate; the cable adjustment part consists of a first fine-tuning screw (with a V-groove), a positioning bead, a fine-tuning wedge (sloping surface), and a pointer; the core cable adjustment part adds an upper wedge, a compression spring, and a movable washer. Its core mechanism involves rotating the fine-tuning screw, which, through the threaded joint, converts the movement of the wedge into horizontal movement, and then the wedge's slope converts this horizontal movement into vertical movement of the crimping component, achieving height adjustment. The screw has 10 V-grooves (1mm pitch), and the wedge has an 11.5° bevel angle. Each rotation allows for precise adjustment of 0.02mm, providing a wide adjustment range and high accuracy. It can adjust the crimping height of the outer wire and the core wire separately, making it suitable for adjusting the molds of high-precision crimping machines.
