Description

Technical Field

[0001] This application relates to the field of cable manufacturing and processing, and in particular to a deburring device for cable conductors. Background Technology

[0002] In the cable manufacturing process, chemical cross-linking is a treatment process used to improve the physical properties of the conductors. Chemical cross-linking is generally achieved through condensation polymerization and addition polymerization reactions, such as the vulcanization of rubber and the curing of unsaturated polyester resins. After appropriate cross-linking, linear polymers exhibit improvements in mechanical strength, elasticity, dimensional stability, and solvent resistance.

[0003] In chemical crosslinking processes, friction between the conductor blank and the equipment during wiring can cause burrs to form on its surface, negatively impacting subsequent crosslinking treatments. Utility Model Content

[0004] To address the aforementioned issues, this application provides a deburring device for cables and conductors.

[0005] The deburring device for cables and conductors provided in this application adopts the following technical solution:

[0006] A deburring device for cable conductors includes a frame on which a plurality of grinding strips are arranged. The plurality of grinding strips are arranged circumferentially along the conductor blank, and the conductor blank passes through the grinding strips and comes into contact with the grinding strips.

[0007] By adopting the above technical solution, during the movement of the conductor blank, its surface comes into contact with and rubs against the grinding strip, thus grinding the surface of the conductor blank and removing the burrs on the surface of the conductor blank.

[0008] Preferably, an adjusting ring is rotatably mounted on the frame, one end of the grinding strip is fixed relative to the frame, and the other end is fixed relative to the adjusting ring, and the wire blank passes through the adjusting ring.

[0009] By adopting the above technical solution, the adjusting ring is rotated, and each grinding strip moves towards the center, close to and against the surface of the wire blank. At this time, the grinding strip is twisted and bent. The greater the deflection angle at both ends of the grinding strip, the greater the contact force between the grinding strip and the side wall of the wire blank, and the higher the grinding force.

[0010] Preferably, the frame includes a first mounting plate, the adjusting ring is rotatably mounted on the first mounting plate, an anti-rotation pin is slidably mounted on the adjusting ring, the sliding direction of the anti-rotation pin is parallel to the axis of the adjusting ring, the first mounting plate has an anti-rotation hole for inserting the anti-rotation pin, the first mounting plate has a first mating hole for passing through the wire blank, and the adjusting ring and the first mating hole are coaxial.

[0011] Preferably, a connecting spring is connected between the adjusting ring and the anti-rotation pin. The extension and retraction direction of the connecting spring is parallel to the sliding direction of the anti-rotation pin. In its natural state, the anti-rotation pin passes through the adjusting ring and is inserted into the anti-rotation hole.

[0012] By adopting the above technical solution, the connecting spring applies tension to the anti-rotation pin, causing the anti-rotation pin to pass through the adjusting ring and be inserted into the anti-rotation hole. The adjusting ring cannot rotate, and the magnitude of the contact force between the grinding strip and the wire blank is relatively determined.

[0013] Preferably, the frame further includes a second mounting plate, on which a second mating hole is provided for the wire blank to pass through. The second mating hole and the first mating hole are coaxial. The first mounting plate, the second mounting plate, and the adjusting ring are all provided with a wire feeding notch. The wire feeding notch is connected to the first mating hole, the second mating hole, or the inner space of the adjusting ring.

[0014] By adopting the above technical solution, when a new batch of wire blanks is pulled, the wire release notch is used to improve the convenience of placing the wire blanks between each grinding strip.

[0015] Preferably, the adjusting ring includes an abutting ring portion and a mating ring portion that are coaxially and fixedly connected to each other. The outer diameter of the abutting ring portion is larger than the outer diameter of the mating ring portion. The abutting ring portion abuts against the side of the first mounting plate opposite to the second mounting plate. The outer wall of the mating ring portion contacts the wall of the first mating hole.

[0016] Preferably, the grinding strip is provided with mounting bolts, which are screwed into the second mounting plate or mating ring after passing through the grinding strip.

[0017] By adopting the above technical solution, the grinding strip is installed and fixed through bolt thread connection.

[0018] Preferably, a connecting rod is fixedly connected to the side of the second mounting plate facing the first mounting plate. The connecting rod passes through the first mounting plate, and the length direction of the connecting rod is perpendicular to the surfaces of the first and second mounting plates. Two fixing nuts are threaded onto the connecting rod, and the two fixing nuts abut against opposite sides of the first mounting plate.

[0019] By adopting the above technical solution, the relative distance between the first mounting plate and the second mounting plate can be fixed, reducing the impact of changes in the tension of the grinding strip on the stability of the distance between the two mounting plates.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By setting multiple grinding strips around the conductor blank, the surface of the conductor blank comes into contact with and rubs against each other during the movement of the conductor blank, thus grinding the surface of the conductor blank and removing the burrs on the surface of the conductor blank.

[0022] 2. By setting the adjusting ring, one end of the grinding strip is relatively fixed to the frame, while the other end can rotate around the wire. When the adjusting ring rotates, the non-fixed end of the grinding strip rotates accordingly. The degree of contact between each grinding strip and the wire blank is different, thereby realizing the adjustment of the grinding intensity. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses a deburring device for cable conductors, such as... Figure 1 As shown, the machine includes a frame 1, and the wire blank 2 moves horizontally towards the chemical crosslinking station. The frame 1 is equipped with three grinding strips 5, which are rubber strips with a frosted surface. During the movement of the wire blank 2, the grinding strips 5 will contact the side wall of the wire blank 2 and rub against it to grind its surface.

[0028] like Figure 1 and 2As shown, the frame 1 includes a first mounting plate 12 and a second mounting plate 13. The surfaces of the first mounting plate 12 and the second mounting plate 13 are parallel. The first mounting plate 12 has a first mating hole 121 through which the wire blank 2 passes, and the second mounting plate 13 has a second mating hole 131 through which the wire blank 2 passes. A connecting rod 14 is fixedly connected to the side of the second mounting plate 13 facing the first mounting plate 12. The connecting rod 14 passes through the first mounting plate 12, and its length direction is perpendicular to the surfaces of the first mounting plate 12 and the second mounting plate 13. Each connecting rod 14 is threaded with two fixing nuts 141, which abut against opposite sides of the first mounting plate 12, thereby fixing the first mounting plate 12 and the second mounting plate 13 relative to each other. The first mating hole 121 and the second mating hole 131 are coaxial. The wire blank 2 first passes through the first mating hole 121 and then through the second mating hole 131.

[0029] like Figure 1 and 2 As shown, an adjusting ring 3 is rotatably mounted on the first mounting plate 12 on the frame 1. The adjusting ring 3 includes an abutting ring portion 31 and a mating ring portion 32 that are coaxially and fixedly connected to each other. The outer diameter of the abutting ring portion 31 is larger than the outer diameter of the mating ring portion 32. The abutting ring portion 31 abuts against the side of the first mounting plate 12 opposite to the second mounting plate 13, and the outer wall of the mating ring portion 32 contacts the wall of the first mating hole 121. The grinding strip 5 is located between the first mounting plate 12 and the second mounting plate 13. Each grinding strip 5 is provided with two mounting bolts 51, which are located at both ends of the grinding strip 5. One mounting bolt 51 is screwed into the second mounting plate 13, and the other mounting bolt 51 is screwed into the mating ring portion 32, thereby realizing the installation of the grinding strip 5.

[0030] like Figure 1 and 2As shown, three grinding strips 5 are arranged in a circumferential array around the second mating hole 131 or the adjusting ring 3, and the wire blank 2 passes through the middle of the three grinding strips 5. When the adjusting ring 3 is rotated, each grinding strip 5 moves towards the center, close to and against the surface of the wire blank 2. At this time, the grinding strips 5 twist and bend. The greater the deflection angle at both ends of the grinding strips 5, the greater the abutment force of the grinding strips 5 against the side wall of the wire blank 2, and the higher the grinding force. An anti-rotation pin 33 is slidably provided on the abutting ring 31 of the adjusting ring 3. The sliding direction of the anti-rotation pin 33 is parallel to the axis of the adjusting ring 3. The first mounting plate 12 has multiple anti-rotation holes 122 for inserting the anti-rotation pin 33. A connecting spring 331 is connected between the adjusting ring 3 and the anti-rotation pin 33. The extension and retraction direction of the connecting spring 331 is parallel to the sliding direction of the anti-rotation pin 33. In the natural state, when the anti-rotation pin 33 and the anti-rotation hole 122 are aligned, the connecting spring 331 applies a pulling force to the anti-rotation pin 33, causing the anti-rotation pin 33 to pass through the adjusting ring 3 and insert into the anti-rotation hole 122. The adjusting ring 3 cannot rotate, and the magnitude of the abutting force of the grinding strip 5 on the wire blank 2 is relatively determined.

[0031] like Figure 1 and 2 As shown, the first mounting plate 12, the second mounting plate 13, and the adjusting ring 3 are all provided with a wire feeding notch 4. The wire feeding notch 4 communicates with the first mating hole 121, the second mating hole 131, or the inner space of the adjusting ring 3. The wire feeding notch 4 is located on the upper edge of the first mounting plate 12 or the second mounting plate 13. When the length direction of each grinding strip 5 is horizontal, the wire feeding notch 4 on the adjusting ring 3 is also located on its upper side. When a new batch of wire blanks 2 is pulled, the wire feeding notch 4 is used to improve the convenience of placing the wire blanks 2 between each grinding strip 5.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
