Description

Technical Field

[0001] This article belongs to the field of wire stripping machine technology, specifically involving a high-efficiency manual cable stripping machine with equal spacing. Background Technology

[0002] In fields such as power engineering, communications, and automotive wiring harness manufacturing, wire stripping machines are widely used in the processing of high-precision cables such as power cables, optical fibers, and data cables. Although there are many types of wire stripping equipment on the market, they generally suffer from problems such as limited functionality, poor adaptability, and insufficient safety, making it difficult to meet the needs of different application scenarios.

[0003] While wire strippers are low-cost and portable, they are inefficient and entirely dependent on manual operation, which can easily damage conductors and limits their applicability to wire diameters. Semi-automatic wire strippers are more efficient and suitable for small to medium batch production, but their complex adjustment process requires manual adjustment of blade spacing and stripping length when changing wire types. In addition, their pneumatic systems are susceptible to air pressure fluctuations, making it difficult to guarantee stripping consistency. Fully automatic wire strippers, despite their significant advantages in efficiency and precision, face practical problems such as high price, complex operation, and insufficient compatibility with ultra-fine or irregularly shaped wires. More importantly, existing wire stripping equipment still has significant room for improvement in key technical indicators such as stripping precision, operational safety, and the ability to process multiple wires simultaneously. Utility Model Content

[0004] This paper proposes a highly efficient manual cable stripping machine that combines existing wire stripping technology. Compared with manual wire strippers, it significantly improves processing efficiency and avoids conductor damage. Compared with traditional semi-automatic equipment, it shortens adjustment time and reduces the impact of air pressure fluctuations. Compared with fully automatic models, it significantly reduces costs while maintaining considerable processing accuracy.

[0005] A high-efficiency manual cable stripping machine includes a base, a control box, a foot pedal, a mechanical clamping assembly, a movable base plate, a mechanical blade assembly, a wire stopper, and a pneumatic system. The mechanical clamping assembly is fixed to the left side of the upper surface of the base. The movable base plate is mounted on the middle of the upper surface of the base via a guide rail and is located behind the mechanical clamping assembly. The mechanical blade assembly is located on the left side of the upper surface of the movable base plate and aligned with the center of the mechanical clamping assembly's axis. The wire stopper is coaxially mounted behind the mechanical blade assembly. The pneumatic system is located on the right side of the base and is connected to the control box via a signal line. It drives the air valves of the mechanical clamping assembly, the mechanical blade assembly, and the movable base plate via air pipes. The components on the left side are arranged sequentially along the axis, forming a linear layout of "mechanical clamping assembly - movable base plate - mechanical blade assembly - wire stopper". The pneumatic system centrally controls the three-axis motion, ensuring the timing coordination of clamping, cutting, and stripping actions.

[0006] The mechanical clamp adopts a modular design, mainly consisting of a clamp fixing base, a fixed clamp, a movable clamp, and symmetrically arranged rubber pads. The clamp fixing base is fixedly installed on the left side of the upper surface of the base, and its upper surface is provided with left and right guide rails. The fixed clamp is rigidly connected to the left side of the upper surface of the clamp fixing base, and the movable clamp is slidably connected to the base through the left and right guide rails and is precisely driven by the clamp cylinder. The symmetrical rubber pads are embedded between the clamping surfaces of the movable clamp and the fixed clamp, which not only ensures clamping stability but also effectively prevents cable damage.

[0007] The movable base plate is slidably connected to the base via front and rear guide rails and is powered by a stripping cylinder, enabling it to move precisely back and forth along the guide rails, thus ensuring stability and positioning accuracy during the cable stripping process.

[0008] The mechanical cutting tool set adopts a modular design, mainly consisting of a fixed base, a fixed tool holder, a movable tool holder, and symmetrically arranged double blades. The fixed base is fixedly installed on the left side of the upper surface of the movable base plate, and its upper surface is equipped with left and right guide rails. The fixed tool holder is rigidly connected to the left side of the upper surface of the fixed base, while the movable tool holder is slidably connected to the base through the left and right guide rails and is precisely driven by a tool cylinder. The double blades are symmetrically arranged between the movable tool holder and the fixed tool holder. The movable tool holder driven by the cylinder achieves precise adjustment of the cutting distance, ensuring accurate cutting of cables of different specifications while maintaining a flat cut and avoiding damage to the internal conductor. This structural design not only ensures wire stripping accuracy but also adapts to the processing needs of different wire diameters.

[0009] The cable guide features a stable support structure design, achieving reliable fixation through an axial bracket and a connecting bracket. The axial bracket is perpendicular to the rear of the fixed blade holder of the mechanical blade assembly and is rigidly connected to it, ensuring support stability. The connecting bracket serves as a transition component, with its two ends connected to the axial bracket and the cable guide respectively, forming a complete support system. This support structure not only ensures the coaxiality of the cable guide and the blade assembly but also effectively resists the reaction force generated during the wire stripping process, ensuring the accuracy of cable positioning and the stability of the operation. The specially designed connecting bracket can be adjusted in position according to different cable length requirements, greatly improving the applicability and ease of operation of the equipment.

[0010] The pneumatic system adopts a modular design, mainly composed of clamping cylinders, cutting tool cylinders, stripping cylinders, air valves, and air pipes. The air valves serve as the control center, connected to the control box via signal lines for control. Simultaneously, the three cylinders are connected in parallel via air pipes. The clamping cylinders drive the moving clamps of the mechanical clamping assembly to clamp the cable, the cutting tool cylinders control the moving tool holders of the mechanical cutting tool assembly to complete the cutting action, and the stripping cylinders drive the moving base plate to perform the stripping operation. This centralized air supply and decentralized execution air circuit design allows for the coordinated control of the timing actions of the three cylinders through a single air valve, ensuring precise coordination of the three processes. Each cylinder is equipped with an independent speed control valve, which can flexibly adjust the action speed according to different cable materials and specifications, making the equipment more adaptable.

[0011] The control box, as the core controller, regulates the opening and closing of the air valve through signal lines. It also receives operation commands from the foot pedal. When the foot pedal is pressed, a trigger signal is transmitted to the control box. After processing by the program, the control box outputs corresponding control signals to manipulate the operation of the air valve, realizing precise timing control of the pneumatic system. The control box can preset multiple working modes to adapt to the processing needs of different cable specifications, greatly improving the ease of operation of the equipment.

[0012] The stripping cylinder has an adjustable stroke, ensuring that the maximum effective stroke of the cylinder is precisely matched with the maximum stripping length preset by the wire stopper. This allows the equipment to adapt to different stripping requirements. Simply adjust the position of the wire stopper according to the cable processing requirements, and the stripping cylinder will automatically adapt to the corresponding working stroke.

[0013] Beneficial effects:

[0014] This paper presents a high-efficiency manual cable stripping machine with equal spacing. It employs an innovative modular structure and intelligent pneumatic control system, achieving a comprehensive breakthrough in performance indicators. The equipment is based on a linear layout design of "mechanical clamping group - moving base plate - mechanical blade group - wire abutment," and is equipped with a centralized air supply and decentralized execution pneumatic system to ensure precise timing coordination of the clamping, cutting, and stripping processes. The mechanical clamping group uses a symmetrical rubber pad design, which can stably clamp the cable while avoiding damage. The adjustable stroke stripping cylinder and the wire abutment are intelligently matched. Combined with multiple preset working modes in the control box, a single unit can flexibly adapt to the processing needs of cables of different specifications. This equipment is particularly suitable for high-precision cable processing fields such as power construction and automotive wiring harness manufacturing. While ensuring high efficiency and accuracy, this equipment significantly reduces operating costs, providing the industry with a high-performance and cost-effective solution.

[0022] A high-efficiency manual cable stripper mainly consists of a base 14, a control box 11, a foot pedal 12, a mechanical clamping assembly 1, a movable base plate 15, a mechanical blade assembly 2, a wire stopper 5, and a pneumatic system. The mechanical clamping assembly 1 is fixedly installed on the left side of the upper surface of the base 14. The movable base plate 15 is installed in the middle of the upper surface of the base 14 via a guide rail, located behind the mechanical clamping assembly 1. The mechanical blade assembly 2 is located on the left side of the upper surface of the movable base plate 15, with its axis precisely aligned with the center line of the mechanical clamping assembly 1. The wire stopper 5 is installed behind the mechanical blade assembly 2, maintaining a coaxial relationship with it. The pneumatic system is located on the right side of the base 14 and is connected to the control box 11 via a signal line. It uses an air pipe 10 to drive the cylinder actuators of the mechanical clamping assembly 1, the mechanical blade assembly 2, and the movable base plate 15, respectively, to achieve coordinated operation of each functional module.

[0023] Mechanical clamping assembly 1 consists of a clamping assembly fixed base, a fixed clamp, a movable clamp, and symmetrically arranged rubber pads. The clamping assembly fixed base is fixed to the left side of the upper surface of the base 14, and its upper surface is equipped with left and right guide rails. The fixed clamp is tightly connected to the left side of the clamping assembly fixed base, while the movable clamp is slidably connected through the guide rails and is driven to move left and right by the clamping cylinder 6. Rubber pads are embedded on the clamping surfaces of both the movable clamp and the fixed clamp to ensure clamping stability. Mechanical tool assembly 2 also includes a tool assembly fixed base, a fixed tool holder, a movable tool holder, and symmetrical double blades. The tool assembly fixed base is located on the left side of the upper surface of the movable base plate 15, and its upper surface is also equipped with left and right guide rails. The fixed tool holder is fixed to the left side of the base, and the movable tool holder slides through the guide rails and is driven by the tool cylinder 7. The double blades are symmetrically arranged between the two. The line stopper 5 is connected by a shaft. The axial support 3 and the connecting support 4 provide fixed support. The axial support 3 is vertically fixed to the rear side of the tool holder of the tool assembly. The two ends of the connecting support 4 are respectively connected to the support 4 and the wire stopper 5.

The control box 11 precisely controls the opening and closing of the air valve 9 through the signal line. The foot pedal 12 sends the trigger command through the signal line. The stroke of the stripping cylinder 8 is adjustable. Its maximum stroke is precisely matched with the maximum stripping length set by the wire stopper 5 to ensure operational coordination. The movable base plate 15 is slidably connected to the base 14 through the front and rear guide rails and is driven to move back and forth by the stripping cylinder 8 to realize the coordinated operation of the overall mechanical structure.

[0024] Implementation Example

[0025] When operating this manual wire stripper, first connect the air and power supply, select the appropriate processing program, adjust the blade spacing according to the thickness of the cable 13, then select the length to be stripped, determine the position of the wire stopper 5, place the wire horizontally into the mechanical clamp group 1, push it forward until it hits the wire stopper 5, and gently press the foot pedal 12. The machine will automatically complete three actions: first, the mechanical clamp group 1 firmly fixes the cable 13, then the blades of the mechanical blade group 2 precisely cut the outer sheath, and finally the base plate 15 moves backward to strip off the outer sheath. The whole process only takes 2-3 seconds. After releasing the foot pedal, the machine automatically resets, and you can take out the stripped cable 13 to continue processing the next one. This is both labor-saving and efficient, faster than traditional wire stripping, and the cut is neat and will not damage the internal metal wire.
