Description

Technical Field

[0001] The present invention belongs to the technical field related to cable cutting, and in particular relates to a wire cutting device and a wire cutting method for communication engineering. Background Art

[0002] Wires are usually made of copper or aluminum. Copper has good conductivity and corrosion resistance and is the most commonly used conductor material. The conductivity of aluminum is slightly inferior to that of copper, but it is light and low in cost. It is also widely used in some occasions where the conductivity requirements are not extremely high. The insulation layer is wrapped around the outside of the conductor to prevent current leakage and electric shock accidents. There are many kinds of insulating materials, such as polyvinyl chloride, polyethylene, etc. Some wires are also provided with a sheath protective layer on the outside. When cutting the wires, they need to be peeled off layer by layer.

[0003] After searching, the applicant found a Chinese invention patent with patent publication number CN115608887B, entitled A cutting device for cable processing. The device cuts off the cable end by a cutting component to make the welding end of the cable smooth and easy for subsequent welding; the two layers of cable sheath are cut off separately by a cutting component to replace manual cutting; the cable joints are assembled and welded by an assembling component and a welding component respectively; however, there are some shortcomings in the actual use of the above device.

[0014] A method for cutting electric wires for communication engineering, comprising the following steps:

[0015] Step 1: Insert the cable body between the clamping rings. Under the elastic force of the first spring, the roller clamps the cable body. After the clamping is stable, hold the first handle and insert the second plug rod provided on the limit ring into the plug hole at the corresponding position of the first plug rod to limit the extended position of the first plug rod. The limit ring is magnetically connected to the clamping ring to ensure the stability of the clamping of the cable body.

[0016] Step 2: The rotation of the bidirectional motor drives the first gear to rotate, and then, under the cooperation of the first gear teeth and the second gear teeth, drives the rotating ring to rotate, drives the cutting motor arranged on the rotating ring to rotate, and performs annular cutting on the cable body. The rotation of the bidirectional motor drives the reciprocating screw rod to rotate, and then drives the reciprocating slider to move back and forth, and then drives the second connecting rod connected to the reciprocating slider to move back and forth. When the second connecting rod contacts the second adjusting rod arranged on the adjusting plate, it drives the second adjusting rod to rotate, and drives the threaded rod to rotate. When the reciprocating slider moves back, under the action of the second rotating shaft and the torsion spring, the second adjusting rod is not driven to rotate. When the threaded rod rotates, the rotating plate can only move along the direction of the threaded rod under the limitation of the third plug rod, drives the third plug rod to move toward the side close to the cable body, drives the cutting motor and the cutting blade to move toward the side close to the cable body, and the cutting depth gradually deepens.

[0017] Step 3: During the reciprocating movement of the reciprocating slider, the fourth connecting plate is driven to reciprocate. When the arc surface set on the hook rod contacts the cutting layer of the cable body, if it is not a complete cutting layer, the cutting layer will not be brought down when the hook rod moves back. If it is a complete cutting layer, the hook rod will bring the cutting layer down, and when it moves to the collecting hook position, the collecting hook will collect the cutting layer on it for the convenience of the next step of processing.

[0018] The beneficial effects of the present invention are as follows: the clamping part can stably clamp the cable bodies of different diameters, and then under the drive of the bidirectional motor, the rotating unit drives the cutting motor to rotate to drive the cutting blade to cut the cable body, and the coordinated setting of the bidirectional motor and the depth adjustment unit can drive the cutting depth of the cutting motor to be adjusted little by little, so as to gradually adapt to different cable layers.

8. The wire cutting device for communication engineering as claimed in claim 7, characterized in that: The material collecting unit comprises a fourth connecting plate (301) fixedly connected to the reciprocating slider (209), the fourth connecting plate (301) being connected to the second connecting frame (302), the upper and lower ends of the second connecting frame (302) being both provided with fourth plug rods (303), the outward end of the fourth plug rod (303) being fixedly connected to a fifth connecting plate (304), the fifth connecting plate (304) being connected to the second connecting frame (302) via a second spring (305) for providing elastic force, The second spring (305) is sleeved on the outside of the fourth insertion rod (303), and the inner side of the fourth insertion rod (303) is fixedly connected to a material hook rod (306), and an arc surface (307) is provided on the material hook rod (306). The base (1) is fixedly connected to a sixth connecting plate (308), and the side of the sixth connecting plate (308) is fixedly connected to two symmetrically arranged third connecting rods (309), and the ends of the two third connecting rods (309) are fixedly connected to material collection hooks (310).

9. A method for cutting electric wires for communication engineering, characterized in that: The invention comprises a wire cutting device for communication engineering as claimed in any one of claims 1 to 8, wherein the steps include: Step 1: Insert the cable body (2) between the clamping rings (101), and under the elastic force of the first spring (107), the roller (106) clamps the cable body (2). After the clamping is stable, hold the first handle (113), insert the second plug rod (111) provided on the limiting ring (110) into the plug hole (112) at the corresponding position of the first plug rod (103), limit the extended position of the first plug rod (103), and magnetically connect the limiting ring (110) and the clamping ring (101), so as to ensure the stability of the clamping of the cable body (2); Step 2: The rotation of the bidirectional motor (5) drives the first gear to rotate, and then, under the cooperation of the first gear teeth (202) and the second gear teeth (206), drives the rotating ring (203) to rotate, drives the cutting motor (3) arranged on the rotating ring (203) to rotate, and performs circular cutting on the cable body (2). The rotation of the bidirectional motor (5) drives the reciprocating screw rod (207) to rotate, and then drives the reciprocating slider (209) to move back and forth, and then drives the second connecting rod (211) connected to the reciprocating slider (209) to move back and forth. When the second connecting rod (211) contacts the second adjusting rod (220) arranged on the adjusting plate (219), When the reciprocating slider (209) moves back, the second adjusting rod (220) is not driven to rotate under the action of the second rotating shaft (212) and the torsion spring (214). When the threaded rod (216) rotates, the rotating plate (221) can only move along the direction of the threaded rod (216) under the limitation of the third plug rod (222), driving the third plug rod (222) to move toward the side close to the cable body (2), driving the cutting motor (3) and the cutting blade (4) to move toward the side close to the cable body (2), and the cutting depth gradually increases; Step 3: During the reciprocating movement of the reciprocating slider (209), the fourth connecting plate (301) is driven to reciprocate. When the arc surface (307) provided on the hook rod (306) contacts the cutting layer of the cable body (2), if it is not a complete cutting layer, the cutting layer will not be brought down when the hook rod (306) moves back. If it is a complete cutting layer, the hook rod (306) will remove the cutting layer and move to the position of the collecting hook (310). The collecting hook (310) will collect the cutting layer on it for the convenience of the next step of processing.
