Description

Technical field:

[0001] The utility model relates to the technical field of wire stripping, in particular to a wire six-blade stripper. Background technology:

[0002] At present, in the production process of industries that need to use wires such as wires and cables, it is often necessary to peel off the wire skin in the middle of the wires such as wires and cables to fully expose the internal guide wires for wiring and other work. The traditional method is to manually place the wires on the operating table to perform the middle stripping operation of the wires. This method is difficult to operate, has high labor costs, low work efficiency, and workers are prone to scratching their hands, poor safety, and high scrap rate. Later, some stripping devices appeared on the market, such as the patent application with publication number CN105811327B, which discloses an asynchronous wheel-type cable longitudinal stripping tool, whose structure is to achieve longitudinal cable stripping by matching a wire clamping device and a cutter head. This structural form only has one cutter head, which is only suitable for stripping the end of the wire, but not for stripping the middle of the wire, because it is still difficult to completely strip and expose after only cutting a crack in the middle of the wire. Therefore, there is currently no good solution for the stripping work in the middle of the wire.

[0003] In summary, how to quickly strip the middle part of the wire has become a technical problem that needs to be solved urgently in the industry. Utility model content:

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a six-knife wire stripper, which solves the problems of difficult operation, low efficiency, poor safety and high scrap rate when stripping the wire in the middle.

[0025] A cover plate 10 is installed on the front side of the six-knife slide disc 1. The cover plate 10 can buckle the six-knife slide disc 1, the slider 4, the blade 5, the pulley 6 and other components inside to play a protective role. At the same time, it can limit the slider 4 in the axial direction to prevent the slider 4 from slipping out of the slide groove 3.

[0026] The cover plate 10 is provided with a front guide turntable 11, on which a plurality of wire holes 12 of different diameters are arranged along the circumference, and the wire holes 12 are aligned with the threading hole 2; the rear end of the support shaft 7 is provided with a rear guide turntable 16, on which a plurality of wire holes 12 of different diameters are arranged along the circumference, and the wire holes 12 are aligned with the threading hole 2. By rotating the front guide turntable 11 and the rear guide turntable 16, the wire holes 12 of different diameters are aligned with the threading hole 2, and wires of different diameters can be guided, including wire diameters of 2-7mm, 4-10mm and 11-20mm.

[0027] The cover plate 10 is provided with a straightening angle 13, which can be used for straightening and positioning during installation.

[0028] A positioning sensor 14 is installed on the cover plate 10, and a positioning sensor switch piece 15 matching the positioning sensor 14 is installed on the outer side of the cam rotating plate 8. When the cam rotating plate 8 rotates, it can drive the positioning sensor switch piece 15 to rotate synchronously. When the positioning sensor switch piece 15 rotates to the positioning sensor 14 to generate an induction signal, the pulley 6 is exactly located at the highest point inside the pulley groove 9, and the blade 5 is also located at the highest point at this time, so as to locate the highest point of the blade 5.

[0029] A rear seat 17 is installed at the rear end of the support shaft 7 , and the rear seat 17 can limit the cam disc 8 in the axial direction.

[0030] A fixing plate 18 is installed on the rear seat 17 for mounting and fixing with other equipment.

[0031] The driving mechanism includes a transmission tooth 19 provided on the cam turntable 8, the transmission tooth 19 is meshed with a gear 20, the gear 20 is mounted on the output shaft of the stepper motor, the stepper motor is mounted on the motor flange plate 21, and the motor flange plate 21 is mounted on the rear seat 17.

[0034] When working, first adjust the minimum height of the blade 5 according to the wire diameter. At the same time, align the wire holes 12 matching the wire diameter on the front guide turntable 11 and the rear guide turntable 16 with the threading hole 2, and fix the front guide turntable 11 and the rear guide turntable 16. Then pass the wire through the wire hole 12 of the front guide turntable 11, the threading hole 2 of the six-knife slide seat disk 1 and the wire hole 12 of the rear guide turntable 16, so that the position to be stripped in the middle of the wire is aligned with the blade 5, and then start the stepper motor. The stepper motor drives the cam turntable 8 to rotate through the gear 20. Under the cooperation of the pulley groove 9 and the pulley 6, the slider 4 drives the blade 5 to cut the wire. When the wire moves forward under the external traction, the six blades 5 cut the wire skin from six directions to complete the wire stripping work.
