Description

Technical Field

[0001] The present invention relates to a stripping machine for the middle section of large cross-section wires and its working method. Background Art

[0002] Existing wire stripping machines are mostly used for stripping wires at the end positions; while in some fields (such as automotive battery cables), wires that require middle-section stripping are needed. Using existing stripping equipment, it is impossible to strip the middle section of the wire. Therefore, only manual stripping can be relied on. And these wires are basically large cross-section wires. So, manual stripping not only has low efficiency and high operation difficulty, but also easily causes damage to the wire core. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a stripping machine for the middle section of large cross-section wires and its working method that is convenient to use, highly practical, and efficient, and is suitable for stripping the middle section of wires.

[0004] The present invention is realized by the following scheme: A stripping machine for the middle section of large cross-section wires includes a base and a substrate located above the base. A through groove is provided on the substrate, and a vertical bracket is vertically arranged in the through groove. A driving device for driving the vertical bracket to move back and forth and left and right is provided on the base; Two connecting plates arranged one above the other and arranged in the front-rear direction and capable of moving synchronously towards or away from each other are installed on the vertical bracket. A pair of knife bodies for cooperating to cut the outer insulating skin of the wire are fixedly connected to the two connecting plates. A semi-circular cutting edge is provided on the side where the two knife bodies face each other; A pair of clamping blocks for cooperating to clamp the wire are also fixedly connected to the two connecting plates. A semi-circular groove adapted to the wire is provided on the side where the two clamping blocks face each other. An axial cutting knife for cutting the outer insulating skin along the axial direction of the wire is provided in the semi-circular groove.

[0005] Further, the vertical bracket is provided with a vertical guide rail and two sliders slidably matched with the vertical guide rail. The rear ends of the two connecting plates are respectively fixedly connected to the two sliders. Two first cylinders for driving the two connecting plates to move synchronously towards or away from each other are installed at the upper and lower ends of the vertical bracket.

[0006] Further, a semi-conical hole is provided on the side where the two knife bodies face each other, and the semi-circular cutting edge is located at the smaller end of the semi-conical hole; The clamping block is located in front of the knife body. The axial cutting knife is wedge-shaped, and the cutting tip of the axial cutting knife corresponds to the position of the semi-circular cutting edge on the knife body in the front-rear direction.

[0007] Further, two clamping mechanisms for clamping both ends of the wire are installed on the upper side of the substrate and are respectively located on both sides of the through groove; each clamping mechanism includes a lower clamping plate fixedly connected to the substrate and an upper clamping plate located above the lower clamping plate. On the opposite sides of the upper and lower clamping plates facing each other, there are semi-circular grooves adapted to the wire. Inside the semi-circular grooves, there are anti-slip bumps protruding inwards. Above the upper clamping plate, there is a second air cylinder for driving the upper clamping plate to move up and down. The second air cylinder is fixed to the substrate through a fixed bracket.

[0008] Further, on the side of the lower clamping plate away from the vertical bracket, there is a limiting stop post fixedly connected to the substrate for restricting the front and rear positions of the wire.

[0009] Further, the driving device includes a three-axis air cylinder for driving the vertical bracket to move back and forth and a rodless air cylinder for driving the three-axis air cylinder to move left and right. The lower end of the vertical bracket is fixedly connected to the end plate of the driving end of the three-axis air cylinder. The three-axis air cylinder is fixedly connected to the sliding seat of the rodless air cylinder; a support frame is connected between the substrate and the base.

[0010] Another technical solution of the present invention: A working method of the middle-section peeling machine for large-square wires as described above includes the following steps: (1) The clamping mechanism clamps both ends of the wire; (2) The initial position of the connecting plate is that the knife body is in the working position. Control the two connecting plates to move towards each other synchronously, so that the two knife bodies first clamp the wire, and the semi-circular knife edges on the two knife bodies cooperate to cut the outer insulating skin of the wire in a whole circumference, forming a first cutting seam; (3) The vertical bracket moves backward, so that the clamping blocks on the connecting plate are in the working position. Control the two connecting plates to move towards each other synchronously to clamp the wire with the two clamping blocks, and then the vertical bracket moves horizontally, so that the axial cutting knives of the two clamping blocks cut the outer insulating skin of the wire along the axial direction of the wire starting from the first cutting seam, forming two second cutting seams, one above and one below; (4) The vertical bracket moves forward, so that the knife bodies on the connecting plate are in the working position again. Control the two connecting plates to move towards each other synchronously, so that the two knife bodies clamp the wire again, and the semi-circular knife edges on the two knife bodies cooperate to cut the outer insulating skin of the wire in a whole circumference at the end position of the second cutting seam, forming a third cutting seam; (5) The clamping mechanism loosens both ends of the wire, and the wire is taken out.

Detailed implementation manners

[0019] Such as Figures 1 to 5As shown in the figure, a stripping machine for the middle section of a large-square wire includes a base 100 and a substrate 200 located above the base 100. A through groove 210 is provided on the substrate 200, and a vertical support 300 is arranged vertically in the through groove 210. A driving device for driving the vertical support to move forward and backward and left and right is provided on the base 100; Two connecting plates 400 arranged one above the other and arranged in the front-back direction and capable of moving synchronously towards or away from each other are installed on the vertical support 300. A pair of knife bodies 410 for cooperating to cut off the outer insulation of the wire are fixedly connected to the two connecting plates 400. A semi-circular cutting edge 411 is arranged on the side of the two knife bodies 410 facing each other; A pair of clamping blocks 420 for cooperating to clamp the wire are also fixedly connected to the two connecting plates 400. A semi-circular groove 421 adapted to the wire is arranged on the side of the two clamping blocks 420 facing each other. An axial cutting knife 422 for cutting open the outer insulation along the axial direction of the wire is arranged in the semi-circular groove. The upper axial cutting knife is located at the middle position in the width direction of the top of the semi-circular groove of the upper clamping block, and the lower axial cutting knife is located at the middle position in the width direction of the bottom of the semi-circular groove of the lower clamping block; The radius of the semi-circular cutting edge is adapted to the radius of the inner core of the wire, the radius of the semi-circular groove on the clamping block is adapted to the radius of the outer insulation of the wire, and the length of the cutting knife extending into the top or bottom surface of the semi-circular groove is the same as the thickness of the outer insulation of the wire. When the two connecting plates move synchronously towards each other, the two knife bodies or the two clamping blocks clamp the wire. When the two connecting plates move synchronously away from each other, the two knife bodies or the two clamping blocks release the clamped wire.

[0020] In the initial state, the knife bodies on the connecting plates are in the working position. When the two knife bodies clamp the wire for the first time, the semi-circular cutting edges on the two knife bodies cooperate to cut off the outer insulation of the wire in a complete circle, forming a first cutting seam. Then the vertical support moves backward, and the two clamping blocks clamp the wire. The vertical support then moves horizontally, so that the axial cutting knives of the two clamping blocks cut open the outer insulation along the axial direction of the wire starting from the first cutting seam, forming two second cutting seams, one above the other. Then the vertical support moves forward, the two knife bodies clamp the wire again, and the semi-circular cutting edges on the two knife bodies cooperate to cut off the outer insulation of the wire in a complete circle at the end position of the second cutting seam, forming a third cutting seam. In this way, it is possible to easily strip the outer insulation of the middle section of the wire located between the first cutting seam and the third cutting seam.

[0021] The stripping machine for the middle section of the large-square wire of the present invention has a novel structure, reasonable design, convenient use, is suitable for stripping the middle section of the wire, reduces the difficulty of stripping the middle section of the large-square wire, is simple and convenient to operate, has high efficiency, strong practicability, avoids damaging the wire core by manual stripping, and has high safety.

[0022] In this embodiment, a vertical guide rail 310 and two sliders 320 slidably engaged with the vertical guide rail are installed on the vertical support 300. The rear ends of the two connecting plates are respectively fixedly connected to the corresponding sliders. Two first cylinders 330 for driving the two connecting plates to move synchronously towards or away from each other are installed at the upper and lower ends of the vertical support 300. The first cylinders at the upper and lower ends of the vertical support 300 work synchronously to achieve the synchronous movement of the two connecting plates towards or away from each other.

[0023] In this embodiment, semi-conical holes 412 are provided on the facing sides of the two tool bodies 410, and the semi-circular cutting edges 411 are located at the smaller ends of the semi-conical holes 412; the clamping blocks 420 are located in front of the tool bodies. The axial cutting knives 422 are wedge-shaped, and the cutting tips of the axial cutting knives correspond to the positions of the semi-circular cutting edges on the tool bodies front and back. This can ensure that the starting end of the second cut is at the first cut, and the third cut is at the end of the second cut.

[0024] In this embodiment, two clamping mechanisms 500 for clamping both ends of the wire are installed on the upper side of the substrate 200 and are respectively located on both sides of the through groove; the clamping mechanism 500 includes a lower clamping plate 510 fixedly connected to the substrate and an upper clamping plate 520 located above the lower clamping plate. Semi-circular grooves for mating with the wire are provided on the facing sides of the upper and lower clamping plates. A second cylinder 530 for driving the upper clamping plate to move up and down is provided above the upper clamping plate. The second cylinder is fixed to the substrate through a fixed bracket 540. The fixed bracket is L-shaped. When performing wire stripping operations, both ends of the wire are clamped and fixed on the clamping mechanisms on both sides.

[0025] In this embodiment, a limit stop post 550 fixedly connected to the substrate is provided on the side of the lower clamping plate 200 away from the vertical support; setting the limit stop post can achieve the rapid and accurate placement of the wire, improve efficiency and operation convenience. When both ends of the wire lean against the limit stop post, the wire is just in the middle of the semi-circular grooves of the upper and lower clamping plates.

[0026] In this embodiment, the driving device includes a three-axis cylinder 600 for driving the vertical support to move back and forth and a rodless cylinder 700 for driving the three-axis cylinder to move left and right. The lower end of the vertical support is fixedly connected to the end plate of the driving end of the three-axis cylinder, and the three-axis cylinder is fixedly connected to the sliding seat of the rodless cylinder.

[0027] A working method of the middle-section peeling machine for large-square electric wires as described above includes the following steps: (1) Lean both ends of the electric wire against the limit stop posts, and then use the second cylinder to control the clamping mechanisms on both sides to clamp both ends of the electric wire; (2) The initial position of the connecting plate is that the cutter body is in the working position. The first cylinder controls the two connecting plates to move synchronously towards each other, so that the two cutter bodies clamp the electric wire for the first time. The semi-circular cutting edges on the two cutter bodies cooperate to cut the outer insulating skin of the electric wire around the whole circumference, forming the first cutting seam; then the first cylinder controls the two connecting plates to move synchronously away from each other to loosen the two cutter bodies; (3) The three-axis cylinder drives the vertical support to move backward, so that the clamping blocks on the connecting plate are in the working position. The first cylinder controls the two connecting plates to move synchronously towards each other to clamp the electric wire with the two clamping blocks. Then the rodless cylinder drives the vertical support to move horizontally, so that the axial cutters of the two clamping blocks cut the outer insulating skin of the electric wire along the axial direction of the electric wire starting from the first cutting seam, forming two second cutting seams, one above and one below; the first cylinder drives the two connecting plates to move synchronously away from each other to loosen the two clamping blocks; (4) The rodless cylinder drives the vertical support to move forward, so that the cutter bodies on the connecting plate are in the working position again. The first cylinder controls the two connecting plates to move synchronously towards each other to clamp the electric wire with the two cutter bodies again. The semi-circular cutting edges on the two cutter bodies cooperate to cut the outer insulating skin of the electric wire around the whole circumference at the end position of the second cutting seam, forming the third cutting seam; then the first cylinder drives the two connecting plates to move synchronously away from each other to loosen the two cutter bodies; (5) The rodless cylinder moves horizontally to reset, and the second cylinder controls the clamping mechanisms on both sides to loosen both ends of the electric wire, and the electric wire is taken out.
