Description

Technical Field

[0001] This invention relates to the technical field of wire stripping machines, and more specifically to a synchronous wire stripping device suitable for multiple wire cores in cables. Background Technology

[0002] Cables are a general term encompassing optical cables, electrical cables, and similar types. They are widely used in power transmission, equipment connection, and control installation, and are indispensable basic materials in modern industry and daily life. They are mainly composed of conductors, insulation layers, sheaths, and armor. According to their uses, they can be divided into power cables, communication cables, and control cables. Taking control cables as an example, they are divided into single-strand and multi-strand cables. Multi-strand cables also have distinctions. For example, some cables have multiple strands that are simply twisted together. Stripping them is done automatically, just like with single-strand cables. However, some multi-strand cables have insulated outer sheaths, isolating the strands. This requires stripping each strand individually. Traditionally, this is done manually, separating the strands and stripping each strand individually, which is slow. Therefore, a device that can strip multiple strands simultaneously is needed.

[0028] The wire harness stripping assembly 2 includes a rectangular positioning frame 21 fixed to the base 1. An upper stripping template 22 and a lower stripping template 23, which are staggered and arranged vertically, are respectively inserted in the positioning frame 21. A gap is provided between the upper stripping template 22 and the lower stripping template 23. A transverse and arc-shaped upper through groove 221 and a lower through groove 231 are respectively formed on the lower end face of the upper stripping template 22 and the upper end face of the lower stripping template 23.

On the dovetail-shaped guide strip c of 3; several longitudinal guide grooves 211 are formed on the upper and lower end faces of the positioning frame seat 21, and several T-shaped limiting sliders 28 are inserted into the guide grooves 211. The 28 are respectively inserted and fixed on the fixed template a of the upper peeling template 22 and the lower peeling template 23; several transverse and longitudinally evenly distributed rollers d are embedded on the lower end face of the upper moving template b of the upper peeling template 22 and the upper end face of the upper moving template b of the lower peeling template 23. The rollers d on the upper peeling template 22 are distributed on the rear side of the upper through groove 221, and the rollers d on the lower peeling template 23 are distributed on the front side of the lower through groove 231.

[0030] The positioning frame 21 on the right side of the fixed template a is provided with upper and lower opposing wire stripping knife holders 27. The wire stripping knife holder 27 includes a longitudinally upright wire stripping knife 271. The cutting edge of the wire stripping knife 271 is formed with several arc-shaped wire stripping cuts, and the tail end is fixedly connected to a horizontal feed plate 272. A vertical cutting cylinder 273 is fixedly connected to the feed plate 272. The piston rod of the cutting cylinder 273 passes through the feed plate 272 and is fixedly connected to the upper and lower end faces of the positioning frame 21. Vertical guide posts 274 are inserted on the feed plate 272 on the front and rear sides of the cutting cylinder 273.

[0031] Two sets of vertically distributed translation actuators 26 are fixedly mounted on the positioning frame 21 on the right side of the wire stripper holder 27. The translation actuators 26 include horizontally oriented push cylinders 262, which are fixedly mounted on the upper and lower end faces of the positioning frame 21.

[0033] The cable input guide wheel assembly 5 includes several conveying wheels and a conveying frame. The conveying frame is fixed to the side wall of the base 1, and the conveying wheels are pivotally connected to the conveying frame. The output guide wheel group 4 consists of several groups of upper and lower opposing guide wheels, and the guide wheels are pivotally connected to the front side of the base 1.

[0034] A transversely arranged cable is provided between the conveying wheel of the cable input guide wheel assembly 5 and the guide wheel of the output guide wheel assembly 4. The cable is clamped between the traction wheels 3, and the wire harness at the end of the cable is inserted into the upper through groove 221 of the upper stripping template 22 and the lower through groove 231 of the lower stripping template 23 and extends out of the wire harness stripping assembly 2. The traction wheel 3 can provide a driving force to the cable, so that the wire harness at the end of the cable enters the wire harness stripping assembly 2 and participates in the wire stripping operation of the wire harness stripping assembly 2. When the stripping blade 271 on the wire harness stripping assembly 2 closes and cuts the outer sheath on the wire harness, the traction wheel 3 drives the cable to move to the right, thereby pulling the wire inside the wire harness out of the outer sheath; Figure 1 , 6 As shown.

[0035] The spacing between the upper stripping template 22 and the lower stripping template 23 in the wire harness stripping assembly 2 is equal to the diameter of a single strand in the wire harness at the end of the cable; the spacing setting restricts the stacking of multiple strands in the wire harness, and realizes the flat arrangement of multiple strands.

[0038] The lateral distance between the wire stripper 271 on the wire stripper holder 27 and the fixed template a is less than the stroke of the push cylinder 262 on the translation actuator 26. The push cylinder 262 can move the moving template b to the right side of the wire stripper 271, thereby exposing the combed and separated wire bundle between the wire strippers 271 and facing the wire stripping cut on the wire stripper 271.

[0039] The upper peeling template 22 and the lower peeling template 23 abut against the upper and lower bottom surfaces of the inner side of the positioning frame 21, respectively. The length of the upper peeling template 22 and the length of the lower peeling template 23 are equal, and the length of the lower peeling template 23 is less than the distance between the front and rear inner walls of the positioning frame 21.

[0040] Working Principle: This structure is a synchronous stripping device suitable for multi-core cables. Its stripping mechanism is mainly used for the synchronous stripping of multiple strands within a cable. In use, the cable is inserted into the cable input guide wheel assembly 5. The cable's outer insulation layer is brought into contact with the traction wheel 3. The stripping machine is then started, causing the traction wheel 3 to rotate, thus inserting the multi-strand cable with its outer insulation removed into the wire harness stripping assembly 2. Figure 6 As shown;

[0041] Then, the separation cylinder 25 is activated, causing the upper stripping template 22 to move forward and the lower stripping template 23 to move backward. Through the coordinated movement of the upper and lower stripping templates 22 and 23, the merged multi-strand wires are separated and laid between the upper and lower stripping templates 22 and 23. Figure 7 As shown, each thread is positioned between the needle rollers d;

[0042] Next, the push cylinder 262 is activated, which drives the moving template b to move to the right. Based on the rollers d on the moving template b, it is easy to sort out the multiple strands in the cable, so that the multiple strands are exposed in front of the wire stripper 271 and can be paired with the wire stripping cut on the wire stripper 271. Then, the cutting cylinder 273 is activated to cut the insulation sheath of the multiple strands. Then, the traction wheel 3 is activated, which rotates to drive the cable outward and pulls the wire out from the cut insulation sheath. After the insulation sheath is removed, the wire stripping process is completed.

Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
