Description

Technical Field

[0001] This utility model relates to the technical field of electrical cabinet processing equipment, and in particular to an integrated wire cutting and stripping machine. Background Technology

[0002] Electrical wires need to be cut and stripped before use. The main purpose of cutting and stripping the insulation in circuit connections is to expose the metal conductor inside the wire, allowing current to pass through. After stripping, the copper wire (or other conductive material) inside the wire directly contacts the external circuit, enabling the transmission of electrical signals.

[0003] Currently, after the wire cutting and stripping machine cuts and strips the wires, the exposed wires at both ends are prone to coming apart, affecting subsequent use. Workers still need to manually twist some of the wires at both ends of the stripped wires, which reduces the efficiency of cutting and stripping the wires.

[0004] The aim is to provide an integrated wire cutting and stripping machine to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an integrated wire cutting and stripping machine that can twist several exposed wire strands in a wire after the insulation layer has been removed, thereby improving the efficiency of wire cutting, stripping, and twisting, and facilitating subsequent use.

[0006] To achieve the above-mentioned utility model objectives, an integrated wire cutting and stripping machine is provided, comprising a cutting and stripping machine body, a pair of infeed pressure rollers, a cutting device, and a twisting device;

The pair of rotating shafts are horizontally rotatable, one above the other, on the front end face of the shearing and peeling machine body, and located at the front end of the shearing device. Each rotating shaft is a drive shaft, and its end is connected to a third drive device for driving its rotation. Long strip-shaped inserts are provided along the axial direction on the curved surfaces of the two rotating shafts. Slots are provided on the inner walls of the two pressure rollers, and these slots are adapted to the long strip-shaped inserts, penetrating the rear end of the pressure rollers.

Two connecting rods are horizontally slidably provided on the bracket, each corresponding to one of the two pressure rollers, and the connecting rods are rotatably connected to the outer end of their respective pressure rollers. The second drive device is used to drive the two connecting rods to move in opposite directions in the horizontal direction.

[0010] Preferably, a guide cylinder is horizontally fixed on the front end face of the shearing and peeling machine body. The guide cylinder is located at the front end of a pair of feed rollers and is directly opposite the pair of feed rollers.

[0013] Preferably, a guide housing is provided on the front end face of the shearing and peeling machine body between the twisting device and the shearing device.

[0014] This utility model discloses an integrated wire cutting and stripping machine, which has the following advantages compared with the prior art:

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, an integrated wire cutting and stripping machine includes a cutting and stripping machine body 1, a pair of wire infeed pressure rollers 2, a cutting device 3, and a twisting device 4.

[0022] A pair of feed rollers 2 are disposed at the feed end on the front end face of the shearing and peeling machine body 1; in the pair of feed rollers, one feed roller is an active roller, and its end is connected to a first drive device (not shown in the figure), which is located inside the shearing and peeling machine body 1; the other feed roller is a driven roller.

[0023] The shearing device 3 is disposed on the front end face of the shearing and peeling machine body 1 and is located at the front end of a pair of feed rollers 2.

[0024] In this embodiment, as Figure 1 As shown, a guide cylinder 5 is horizontally fixed on the front end face of the shearing and peeling machine body 1. The guide cylinder 5 is located at the front end of a pair of feed rollers 2 and is directly opposite the pair of feed rollers 2, which facilitates the feeding of the material to the blade of the shearing device 3.

[0025] The twisting device includes a pair of rotating shafts 6, two pressure rollers 7, a bracket 8, and a second drive device; as follows: Figure 2As shown, a pair of rotating shafts 6 are horizontally rotatable, one above the other, on the front end face of the shearing and peeling machine body 1, and located at the front end of the shearing device 3; each of the rotating shafts is a driving shaft, and its end is connected to a third driving device (not shown in the figure) for driving its rotation; long strip-shaped connectors 9 are provided along their axial direction on the curved surfaces of the two rotating shafts 6, such as... Figure 3 As shown, the inner walls of the two pressure rollers 7 are provided with slots 10, which are adapted to the elongated insert body 9, and the slots 10 penetrate through the rear end of the pressure rollers 7. The two pressure rollers 7 are slidably inserted into the rotating shaft 6 through the cooperation of the slots 10 and the elongated insert body 9.

[0026] The bracket 8 is provided with two horizontally sliding connecting rods 11, which correspond one-to-one with the two pressure rollers 7, and the connecting rods 11 are rotatably connected to the outer ends of the corresponding pressure rollers 7; the second driving device is used to drive the two connecting rods 11 to move in opposite directions in the horizontal direction.

[0027] In this embodiment, the second driving device includes a motor 12, a connecting shaft 13, and two first racks 14; the two first racks 14 are respectively fixed on two connecting rods 11; the connecting shaft 13 is horizontally rotatably mounted on the bracket 8, and a first toothed structure 15 is provided on the front end of the connecting shaft. The first toothed structure 15 is located between the two first racks 14 and meshes with the two first racks respectively; the motor is used to drive the connecting shaft to rotate; with this configuration, under the drive of the motor 12, the first toothed structure 15 on the connecting shaft 13 rotates. Since the two first racks 14 are located above and below the connecting shaft 13 respectively, one connecting shaft moves outward while the other connecting shaft moves inward. The two pressure rollers 7 rotate on their own axis and move in opposite directions, twisting the exposed wire ends to prevent them from unraveling and affecting subsequent use.

[0028] In this embodiment, as Figure 4As shown, the shearing device 3 includes a fourth driving device, a rotating shaft 16, a housing 17, an upper blade 18, and a lower blade 19. The fourth driving device (not shown in the drawing) is disposed inside the shearing and peeling machine body 1. The rotating shaft 16 is horizontally rotatably disposed on the front end face of the shearing and peeling machine body 1, and the front end of the rotating shaft 16 has a second annular tooth structure 20. The fourth driving device is used to drive the rotating shaft 16 to rotate. The housing 17 is fixed to the front end face of the shearing and peeling machine body 1. The upper blade 18 and the lower blade 19 are adapted to each other and are both vertically slidably disposed within the housing 17. The lower parts of both the upper cutter 18 and the lower cutter 19 extend out of the housing 17; the upper parts of both the upper cutter 18 and the lower cutter 19 are fixed with second racks 21, and the two second racks 21 mesh with the second annular tooth structure 20 on the rotating shaft 16 and are distributed on both sides of the rotating shaft 16; with this arrangement, under the drive of the fourth driving device, the rotating shaft 16 rotates, and since the two second racks 21 are located on both sides of the second annular tooth structure 20 and mesh with it, the upper cutter 18 and the lower cutter 19 move closer or further away from each other, thereby achieving the function of cutting the wire or cutting the insulation layer of the wire.

[0029] In this embodiment, as Figure 2 As shown, a guide housing 22 is also provided on the front end face of the shearing and peeling machine body 1 between the twisting device 4 and the shearing device 3, so as to facilitate the wire being guided into the twisting device 4.

[0030] When the above-mentioned wire cutting and stripping integrated machine is in use, the wire passes through the infeed pressure roller 2 and guide cylinder 5 in sequence, and enters the blade between the upper blade 18 and the lower blade 19. The upper blade 18 and the lower blade 19 on the cutting device 3 move to cut off the insulation layer at the end of the wire, and several wire strands at the end of the wire are exposed. Then the wire continues to move forward to a pair of pressure rollers 7 on the twisting device 4. The two pressure rollers 7 rotate on their own axis and move in opposite directions to twist the several wire strands exposed at the end of the wire. When the wire moves to a fixed length position, the cutting device 3 cuts and strips the wire (the wire cutting and stripping process is a conventional process). The several wire strands exposed at the rear end are also twisted.

[0031] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
