DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0016] Specific implementation method: Combination Figure 1-3 As shown, a wire cutting device includes a machine 1 and a controller, a wire feeding mechanism 3 is arranged in the middle of the machine 1, and a pressing wheel 32 and a driving wheel 31 arranged up and down are arranged on the wire feeding mechanism 3, and the driving wheel 31 is connected to the rotating shaft of the servo motor, and a first conduit 2 and a second conduit 4 are respectively arranged on both sides of the wire feeding mechanism 3, the inner diameter of the first conduit 2 can be much larger than the diameter of the wire to be cut, and the inner diameter of the second conduit 4 is slightly larger than the diameter of the wire to be cut, and a cutting mechanism 5 is arranged on the side of the second conduit 4 away from the wire feeding mechanism 3, and a wire stripping mechanism 6 is arranged on one side of the cutting mechanism 5, and the wire stripping mechanism 6 is slidably connected to the machine 1, and a servo electric cylinder 8 is arranged between the wire stripping mechanism 6 and the machine 1, and the servo electric cylinder 8 is fixed on the machine 1, and a wire outlet mechanism 7 is arranged on the side of the wire stripping mechanism 6 away from the cutting mechanism 5. Two guide rails can be arranged on the machine 1 , and the two guide rails are respectively located on both sides of the wire stripping mechanism 6 . A hollow portion is arranged between the two guide rails on the machine 1 , so that the peeled wire skin can fall from the hollow portion and will not easily accumulate on the machine 1 .

[0017] Furthermore, the cable feeding mechanism 3 includes an inverted L-shaped plate, the pressure wheel 32 is slidably connected to the top surface of the inverted L-shaped plate, and a spring is arranged between the two, so that the pressure wheel 32 can press the cable on the driving wheel 31 with a certain force. In order to enhance the friction force, a plurality of fine grooves can be arranged on the circumferential surfaces of the pressure wheel 32 and the driving wheel 31, and the extending direction of the grooves is parallel to the axes of the two.

[0018] Specifically, the cutting mechanism 5 includes a first bracket 51, a first channel 511 is provided on the first bracket 51, a first cylinder 53 is provided on the top of the first bracket 51, a piston rod of the first cylinder 53 is connected to a cutter 52, the cutting edge of the cutter 52 is in an inverted V shape, and the axis of the second conduit 4 is on the symmetry plane of the inverted V shape, so that the wires are not easily deviated when cutting the wires.

[0019] Furthermore, the bottom surface of the first channel 511 is parallel to the horizontal plane, and the bottom end of the inner hole of the second conduit 4 is tangent to the bottom surface of the first channel 511 .

[0020] Specifically, the wire stripping mechanism 6 includes a second bracket 61, a second channel 611 is provided on the second bracket 61, and second cylinders 62 are provided on both sides of the second bracket 61. The piston rods of the two second cylinders 62 are respectively connected to the first wire stripping blade 63 and the second wire stripping blade 64. The first wire stripping blade 63 and the second wire stripping blade 64 are provided with semicircular cutting edges on the sides close to each other, and the parts of the side except the cutting edges are flat. When the first wire stripping blade 63 and the second wire stripping blade 64 are in contact on the sides close to each other, the cutting edges on the two form a circle with the same diameter as the wire core, and the radius of the circle is equal to the radius of the wire minus the thickness of the insulation skin, so that the insulation skin can be cut off without basically damaging the wire core. The first wire stripping blade 63 and the second wire stripping blade 64 are provided with guide plates on both upper and lower sides of the semicircular cutting edge. The inner side surface (side surface close to the cutting edge) of the guide plate is an inclined surface, and the inclined surface moves further away from the symmetric surface of the semicircular cutting edge as the distance from the second cylinder 62 increases. The guide plates on the first wire stripping blade 63 and the second wire stripping blade 64 are respectively located on the side close to the cutting mechanism 5 and the side away from the cutting mechanism 5. Since the wire may be located on the upper side or the lower side of the line connecting the two cutting edges when the first wire stripping blade 63 and the second wire stripping blade 64 approach each other, the guide plate can push the wire in the direction of the line connecting the two cutting edges, so that the wire core of the wire can enter the two cutting edges. The distance between the inclined surfaces of the two guide plates on each wire stripping blade at the side where the wire stripping blades approach each other is equal to the outer diameter of the wire.

[0021] Specifically, the structure of the wire outlet mechanism 7 is the same as that of the wire inlet mechanism 3 .

[0022] When using, combine Figure 1As shown, firstly, a single-core wire (the wire stripping operation of this device is only suitable for single-core wires) is passed through the first conduit 2, the wire feeding mechanism 3, the second conduit 4 and the cutting mechanism 5 in sequence, and the wire is exposed a little from the side of the cutting mechanism 5 away from the second conduit 4, and then the cutting mechanism 5 cuts the wire, and then the servo motor on the wire feeding mechanism 3 rotates to make the right end of the wire pass through the wire stripping mechanism 6 and exceed the length required for the two wire stripping blades to strip (the feeding length of the wire is controlled by the number of rotations of the servo motor), and then the two wire stripping blades are closed to cut off the insulation of the wire, and then the wire stripping mechanism 6 moves to the right to remove the cut insulation from The right end of the wire is pushed out, and then the two stripping blades are separated. Then the wire-in mechanism 3 pushes the right end of the wire into the running wire-out mechanism 7. During this process, the wire-stripping mechanism 6 returns to its original position. When the length of the wire on the right side of the cutting mechanism 5 reaches the requirement, the wire-in mechanism 3 and the wire-out mechanism 7 stop running. After the wire-stripping mechanism 6 moves to the required position, the two stripping blades on it close together to cut off the insulation. Then the cutting mechanism 5 cuts the wire, and then the wire-out mechanism 7 runs (the wire-in mechanism 3 does not run) to move the cut wire to the right and finally falls from the right end of the machine 1. During this process, the insulation on the left end of the cut wire segment falls off. After that, the wire-in mechanism 3 runs, pushing the wire to the right, and the next wire segment is cut and stripped.
