[0002] In the production of wire harness products, some cable insulation materials have high hardness and smooth surface, requiring stripping in the middle. The traditional method is to use wire strippers to strip the insulation manually. First, the cable insulation is cut open at both ends of the specified length of the cable to be stripped, and then the blade is used to cut it vertically before the cable insulation is stripped off. This method is inefficient, easily scratches or breaks the conductor copper wire, and the blade can easily cut the hand when operating manually. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cable stripping device, including a fixed mold base, a movable mold base, and a driving mechanism for driving the movable mold base to approach or move away from the fixed mold base. A semi-circular through groove is respectively formed on the facing surfaces of the fixed mold base and the movable mold base. When the fixed mold base and the movable mold base are aligned, the two semi-circular through grooves are joined together to form a through hole with a diameter adapted to the outer diameter of the cable. A fixed blade is fixedly attached to each end of the semi-circular through groove of the fixed mold base. The fixed blade is provided with a semi-circular cutting edge coaxial with the semi-circular through groove. The radius of the semi-circular cutting edge of the fixed blade is smaller than the radius of the semi-circular through groove, and the difference between the radii is equal to the thickness of the cable sheath. A movable blade is fixedly attached to each end of the semi-circular through groove of the movable mold base. The movable blade is provided with a semi-circular cutting edge coaxial with the semi-circular through groove. The radius of the semi-circular cutting edge of the movable blade is smaller than the radius of the semi-circular through groove, and the difference between the two radii is equal to the thickness of the cable sheath. A vertical blade is provided at the bottom of the semi-circular through groove of the movable mold base. The vertical blade extends along the axial direction of the semi-circular through groove and connects with the two movable blades. The height of the vertical blade protruding from the bottom of the semi-circular through groove is equal to the thickness of the cable sheath. When the fixed mold base and the movable mold base are aligned, the two movable blades and the two fixed blades are aligned one to one. When the fixed mold base and the movable mold base are aligned, the semi-circular cutting edges of the corresponding movable blades and fixed blades are joined to form a complete ring.

[0005] As a preferred embodiment, the fixed mold base is detachably connected to the lower base plate of the support, the movable mold base is detachably connected to the upper movable base plate, the drive mechanism is fixedly connected to the support, and the output end of the drive mechanism is connected to the upper movable base plate.

[0006] As a preferred embodiment, a guide rod is connected to each of the four corners of the lower base plate. The four guide rods are parallel to each other and parallel to the moving direction of the movable mold base. The movable upper base plate is slidably sleeved on the four guide rods. The four guide rods are arranged in a matrix. Both the fixed mold base and the movable mold base are set within a rectangular frame formed by the four guide rods.

[0007] As a preferred embodiment, the lower end of the bracket is fixedly connected to the lower base plate, and the upper end of the bracket is fixedly connected to a suspension beam, which is fixedly connected to a drive mechanism located directly above the lower base plate.

[0008] As a preferred embodiment, the drive mechanism is a pneumatic cylinder or a hydraulic cylinder.

[0009] The beneficial effects of this utility model are as follows: This utility model uses a fixed mold base and a movable mold base to position the cable, and at the same time uses a fixed blade and a movable blade to perform a circumferential cut on the middle outer sheath of the cable. Then, a vertical blade is used to make a vertical cut between the two circumferential cuts on the outer sheath of the cable, thereby forming an "I" shaped cut on the outer sheath of the cable. The user only needs to peel off the outer sheath from the vertical cut. The process of cutting the cable outer sheath using the cable middle stripping device described in this utility model is efficient and safe. No sharp tools are required during stripping, and the operation process is highly safe. Attached Figure Description

[0017] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] like Figures 1-4 The cable stripping device shown includes a fixed mold base 1, a movable mold base 2, and a driving mechanism 3 for moving the movable mold base 2 closer to or away from the fixed mold base 1. A semi-circular through-slot 4 is respectively formed on the facing surfaces of the fixed mold base 1 and the movable mold base 2. When the fixed mold base 1 and the movable mold base 2 are aligned, the two semi-circular through-slots 4 are joined together to form a through hole with a diameter adapted to the outer diameter of the cable. A fixed blade 5 is fixedly attached to each end of the semi-circular through-slot 4 of the fixed mold base 1. The fixed blade 5 is provided with a semi-circular cutting edge 6 coaxial with the semi-circular through-slot 4. The radius of the semi-circular cutting edge 6 of the fixed blade 5 is smaller than the radius of the semi-circular through-slot 4, and the difference between the radii is equal to the cable sheath thickness. The movable mold base 2... A movable blade 7 is fixedly attached to each end of the semicircular through groove 4. The movable blade 7 is provided with a semicircular cutting edge 6 coaxial with the semicircular through groove 4. The radius of the semicircular cutting edge 6 of the movable blade 7 is smaller than the radius of the semicircular through groove 4, and the difference between the two radii is equal to the thickness of the cable sheath. A vertical blade 8 is provided at the bottom of the semicircular through groove 4 of the movable mold base 2. The vertical blade 8 extends along the axial direction of the semicircular through groove 4 and connects with the two movable blades 7. The height of the vertical blade 8 protruding from the bottom of the semicircular through groove 4 is equal to the thickness of the cable sheath. The two movable blades 7 and the two fixed blades 5 are directly opposite each other. When the fixed mold base 1 and the movable mold base 2 are engaged, the semicircular cutting edges 6 of the corresponding movable blades 7 and fixed blades 5 are joined to form a complete ring.

[0019] In this embodiment, the fixed mold base 1 is detachably connected to the lower base plate 9, the movable mold base 2 is detachably connected to the movable upper base plate 10, the driving mechanism 3 is fixedly connected to the bracket 11, and the output end of the driving mechanism 3 is connected to the movable upper base plate 10.

[0020] The detachable connection allows users to replace the fixed mold base 1 and movable mold base 2 with the appropriate ones according to different cable specifications, thereby improving the adaptability of the cable stripping device.

[0021] As an improvement to the above technical solution, a guide rod 12 is connected to each of the four corners of the lower base plate 9. The four guide rods 12 are parallel to each other and parallel to the moving direction of the movable mold base 2. The movable upper base plate 10 is slidably sleeved on the four guide rods 12. The four guide rods 12 are arranged in a matrix. The fixed mold base 1 and the movable mold base 2 are both set in a rectangular frame formed by the four guide rods 12.

[0022] Four guide rods 12 are used to guide the movable upper base plate 10 to improve the alignment accuracy between the movable mold base 2 and the fixed mold base 1, improve the matching accuracy between the fixed blade 5 and the movable blade 7, and ensure that the semi-circular blade 6 continuously and completely cuts the cable sheath.

[0023] In this embodiment, the lower end of the bracket 11 is fixedly connected to the lower base plate 9, and the upper end of the bracket 11 is fixedly connected to the suspension beam 13. The suspension beam 13 is fixedly connected to the drive mechanism 3, which is located directly above the lower base plate 9.

[0024] In practical applications, the bracket 11 and the lower base plate 9 can also be separated. However, in order to improve the fitting accuracy of the fixed mold base 1 and the movable mold base 2, the bracket 11 and the lower base plate 9 are fixedly connected. At the same time, the drive mechanism 3 is connected by the suspension beam 13, so that the drive mechanism 3 drives the movable mold base 2 to strictly approach and move away from the fixed mold base 1 along the axial direction of the guide rod 12.

[0025] In this embodiment, the drive mechanism 3 is a cylinder. The cylinder has a relatively high speed, enabling it to impact and cut the cable sheath, overcoming the resistance of the cable sheath's elasticity to cutting. In practical applications, other linear drive mechanisms such as hydraulic cylinders or linear motors can also be used to cut the cable sheath.

[0026] The working process of this utility model is as follows: First, the cable is placed in the semi-circular through groove 4 of the fixed mold base 1. At this time, due to the support of the fixed blade 5, the cable is actually suspended above the semi-circular through groove 4 of the fixed mold base 1 and abuts against the semi-circular blades 6 of the two fixed blades 5.

[0027] Next, the drive mechanism 3 is activated, controlling the drive mechanism 3 to drive the movable mold base 2 to move towards the fixed mold base 1. During the movement of the movable mold base 2, the semi-circular blade 6 of the movable blade 7 on the movable mold base 2 gradually contacts the cable and begins to squeeze the cable sheath. The cable sheath is cut open by the squeezing of the semi-circular blade 6. After the sheath is cut open, the cable is embedded in the semi-circular through groove 4 of the fixed mold base 1 and the movable mold base 2 and is tightly pressed against the semi-circular through groove 4. At the same time, while the semi-circular blade 6 is circumferentially cutting the cable sheath, the vertical blade 8 is vertically cutting the cable sheath, ultimately as follows: Figure 5 As shown, two circumferential slits and one vertical slit are formed on the outer sheath of the cable 14.

[0028] After the cutting is completed, the control drive mechanism 3 drives the movable mold base 2 to reset, takes out the cable 14, and manually peels off the cut outer sheath from the vertical cut to complete the circumferential stripping of the middle outer sheath of the cable.

[0029] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
