Description

Technical Field

[0001] This utility model relates to the field of cable insulation removal technology, and in particular to a wire stripping tool. Background Technology

[0002] In the past, during the manufacturing of rail passenger vehicles, for multi-core cables (including shielded and unshielded cables) with irregular shapes or an outer diameter of less than 6mm, it was impossible to use specialized wire stripping tools. Typically, a PVC knife was used, or a small slit was cut at the end of the cable, and the insulation layer was manually torn upwards. For cables with tight insulation, a knife could be used to assist in cutting. However, if the operator applied inappropriate force, it was easy to damage the surface of the internal cores or the shielding layer during cutting. This method not only wasted materials and increased vehicle manufacturing costs but also reduced production efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the existing technology and provide a wire stripping tool to solve the problem that the surface of the wire core is easily damaged when stripping multi-core cables with irregular shapes or outer diameters of less than 6mm.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model discloses a wire stripping tool, which includes:

[0006] Two symmetrically arranged first steel plates and two second steel plates holding blades are provided. A wire-straightening gap is formed between the opposing surfaces of the first steel plates. The cutting edge of the blade coincides with the edge of the second steel plate and forms an angle with the horizontal plane. The second steel plate and the blade are fixedly connected within the wire-straightening gap so that the blade tip cuts the cable sheath at the midpoint of the wire-straightening gap.

[0007] Furthermore, it also includes bolts that can penetrate the first steel plate and the second steel plate, the bolts clamping the first steel plate and the second steel plate by fastening nuts.

[0008] Furthermore, both the nut and the bolt are in contact with the first steel plate via washers.

[0009] Furthermore, both the first steel plate and the second steel plate are provided with U-shaped grooves that mate with the bolts.

[0010] Furthermore, the U-shaped grooves of the first steel plate and the second steel plate are intersected, and the depth axis of the U-shaped groove of the second steel plate is parallel to the cutting edge of the blade.

[0011] In the above technical solution, the wire stripping tool provided by this utility model has the following advantages:

[0012] The wire stripping tool designed in this utility model utilizes two first steel plates to form a wire-stripping gap, and two second steel plates to hold the blade within the wire-stripping gap. The blade's cutting edge forms an angle with the horizontal plane, enabling the blade tip to apply force evenly along a straight line at the midpoint of the wire-stripping gap to cut the cable sheath. This effectively solves the problem of easily damaging the surface of the wire core when stripping multi-core cables with irregular shapes or outer diameters less than 6mm. Compared with existing technologies, it has the beneficial effects of saving time, effort, and materials. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] See Figure 1 , 2 As shown;

[0020] A wire stripping tool according to a utility model includes: two first steel plates 3 and two second steel plates 5, and a blade 4;

[0021] Two first steel plates 3 are symmetrically arranged, and a straightening gap is formed between the opposite surfaces of the first steel plates 3;

[0022] Two second steel plates 5 are used to clamp the blade 4 relative to each other, see Figure 1 As shown, the cutting edge of blade 4 coincides with the edge of the second steel plate 5 in a straight line, the cutting edge of blade 4 forms a 30° angle with the horizontal plane, and the second steel plate 5 and blade 4 are fixedly connected within the straightening gap (as shown). Figure 2 As shown in the figure, when in use, the blade tip applies a uniform force along a straight line at the midpoint of the cable stripping gap to cut the cable sheath.

[0023] The wire stripping tool also includes a bolt 1 for penetrating the first steel plate 3 and the second steel plate 5. The bolt 1 clamps the first steel plate 3 and the second steel plate 5 by a fastening nut 6. Both the nut 6 and the bolt 1 are in contact with the first steel plate 3 through a washer 2.

[0024] Preferably, both the first steel plate 3 and the second steel plate 5 are provided with U-shaped grooves that cooperate with the bolt 1. The U-shaped grooves of the first steel plate 3 and the second steel plate 5 are arranged intersectingly, and the depth axis of the U-shaped groove of the second steel plate 5 is parallel to the cutting edge of the blade 4. The U-shaped grooves facilitate the adjustment of the position of the blade 4 and control the cutting depth and angle.

[0025] In the above technical solution, the present invention provides a wire stripping tool, the method of use of which is as follows:

[0026] First, after bolt 1 passes through component flat washer 2, first steel plate 3, and second steel plate 5, use flat washer 2 and fastening nut 6 to fasten all the above components, ensuring that the cutting edge of blade 4 coincides with the edge of second steel plate 5 in a straight line, and the cutting edge of blade 4 forms a 30-degree angle with the horizontal.

[0027] A multi-core cable with a cross-section of less than 6 square millimeters is placed in the cable-strapping gap formed between two first steel plates 3. The tip of the blade 4 contacts the cable insulation. Hold the first steel plate 3 and apply force to the first steel plate 3 and the second steel plate 5 so that the tip of the blade 4 exerts a uniform force on the cable insulation along a straight line.

[0028] This wire stripping tool effectively solves the problem of stripping multi-core cables with irregular shapes or outer diameters less than 6mm. It applies a uniform horizontal force along a straight line to the cable, and compared with existing technologies, it has the advantages of saving time, effort, and materials.
