Description

Technical Field

[0001] The invention relates to the technical field of cable production, in particular to a shearing device for power cable production. Background Art

[0002] Power cables are cables used to transmit electricity. They are composed of a multi-layer structure including conductors, insulation layers, and sheaths. The conductors of power cables are generally made of copper, the conductors are wrapped with insulation materials, and there is an outer sheath to provide additional protection to prevent the cable from physical damage or chemical corrosion.

[0003] During the production process, the cable will be cut according to the length required by the actual application, and the outer sheath of the cable will be further cut at the cut point, and the outer sheath will be pushed down to facilitate the subsequent splicing of the cable. When the existing shearing device cuts the length and cuts the outer sheath of the columnar cable, the columnar cable is transported by the conveying mechanism. When it is transported to the appropriate position, it is first cut by the vertical cutter, and then the cutter on the circular moving path cuts the outer sheath in an annular manner, so that the outer sheath near the cut point on the cable is initially cut, and then the outer sheath is pushed away.

[0004] However, for flat cables, the cross section of the flat cable after vertical cutting is a relatively flat ellipse, which is inconvenient to circumferentially cut the outer sheath. At the same time, the outer sheath of the flat cable is relatively thick and fits more closely with the conductor, so it is difficult to separate the outer sheath after initial cutting.

[0035] The supporting mechanism includes two square grooves 20, which are respectively opened at the front ends of the two baffles 10, and square rods 12 are slidably inserted into the inside of the two square grooves 20, one end of the two square rods 12 is fixedly connected to the two square grooves 20 with a spring 19, and the other ends of the two square rods 12 are commonly fixedly connected with a support rod 24, and the front end of the support rod 24 is in contact with the rear ends of the two push blocks 23.

[0036] Working principle: First, place the flat cable body 6 between the two baffles 10, and the cable body 6 will fit exactly between the two baffles 10. Then, insert the cable body 6 between the two conveyors 1 and start the two conveyors 1. The belts on the two conveyors 1 will turn in opposite directions, so that the cable body 6 can be conveyed between the two conveyors 1 toward the cutter 4. The end of the cable body 6 will move out of the two baffles 10, and the cable body 6 will fit in turn on the upper ends of the support rod 24 and the carrier plate 5. The support rod 24 and the carrier plate 5 will be connected. The plate 5 can support the cable body 6 to prevent the cable body 6 from bending downward. After the cable body 6 extends out of the two baffles 10 to a suitable length, the electric push rod 3 is started, and the electric push rod 3 can drive the cutter 4 to move downward, and the cutter 4 can cut the cable body 6 at the upper end of the carrier plate 5 (it should be noted that a knife groove is provided at the upper end of the carrier plate 5 corresponding to the cutter 4, and the cutter 4 will move down to enter the knife groove, which can better cut the cable body 6), and then the cutter 4 is moved up to reset. At this time, the state of the cutter 4 and the cable body 6 is as shown in FIG. Figure 1 and Figure 3 as shown in .

[0037] Then, the outer sheath near the cut-off point on the flat cable body 6 is sheared, and the linear slide 25 is started first. The linear slide 25 can drive the electric slide rail 9 to move forward, and the electric slide rail 9 can drive the two electric push rods 3 13, the two push blocks 23, the two motors 18 and the two triangular blades 17 to move forward together. At the same time, the two electric push rods 2 7 are started to drive the carrier plate 5 to move downward until the upper end surface of the carrier plate 5 is located below the two push blocks 23, and combined with Fig. 9 It can be seen that the forward movement of the two push blocks 23 can be prevented from being blocked by the carrier plate 5, and combined with Fig. 9It can be seen that the width of the carrier plate 5 is smaller than that of the elliptical electric slide rail 9. Even if the carrier plate 5 moves down a short distance, it will not hinder the forward movement of the elliptical electric slide rail 9. When the electric slide rail 9 comes to the front of the cable body 6, the electric slide rail 9 will be on the outside of the carrier plate 5. When each triangular blade 17 moves forward, its upper and lower inclined blade surfaces will respectively push the corresponding two A-shaped electric heating blocks to move, and the two A-shaped electric heating blocks will move away from each other, and each A-shaped electric heating block will drive the corresponding A-shaped electric heating blocks through the connecting block 15. The corresponding guide column 28 slides in the corresponding concave rod 14 and squeezes the corresponding spring 27. Finally, each triangular blade 17 will move to be exactly between the corresponding two A-shaped electric heating blocks, and under the action of the spring 27, the two A-shaped electric heating blocks and the triangular blade 17 are tightly fitted together, and the inclined surfaces of the two A-shaped electric heating blocks will respectively fit exactly with the inclined blade surfaces on the upper and lower sides of the triangular blade 17, so that when the A-shaped electric heating block is started, the heat can be transferred to the triangular blade 17 evenly and quickly.

[0038] When the electric slide rail 9 moves forward, it will also drive the two electric push rods 21, the electric heating plate 31, the multiple vertical blades 26, the concave frame 29, the multiple connecting columns 30, the splicing plate 34 and the multiple connecting plates 22 to move together. When the electric slide rail 9 moves to the front of the cable body 6, the multiple vertical blades 26 will be located in the front and upper part of the cable body 6 (it should be noted that when the multiple vertical blades 26 were located directly above the cable body 6 before, they were respectively corresponding to the multiple conductors in the cable body 6), and at this time, the electric heating plate 31 can be started to heat the multiple vertical blades 26 to a suitable temperature, and after the two triangular blades 17 are also heated to a suitable temperature , start the two electric push rods 13 to drive the motors 18 and triangular blades 17 connected to them to move toward the center of the electric slide rail 9, then the inclined blade surface of each triangular blade 17 will push the corresponding two A-shaped electric heating blocks to expand outward, until the tips of the two triangular blades 17 are cut into the cable body 6, and the tips are close to the conductors at the edges of the cable body 6 on both sides, and then the electric slide rail 9 is driven to move backward through the linear slide 25, which will drive the two triangular blades 17 and the multiple vertical blades 26 to move backward together (it should be noted that the triangular blades 17 leave the corresponding two A-shaped electric heating blocks After that, under the action of the spring 27, the two A-shaped electric heating blocks will reset to prepare for the next heating of the A-shaped electric heating blocks), when the multiple vertical blades 26 move over the upper front edge of the cable body 6 (it should be noted that the vertical blades 26 will not start shearing from the upper front edge of the cable body 6, which is conducive to pushing the sheared outer sheath away at one time later), at this time, the two electric push rods 21 are started to drive the electric heating plate 31, the multiple vertical blades 26, the concave frame 29, the multiple connecting columns 30, the splicing plate 34 and the multiple connecting plates 22 to move downward together until the multiple vertical blades 26 cut into the outer sheath of the cable body 6 , and the bottom ends of the multiple vertical blades 26 will be close to the top of each conductor in the cable body 6 respectively (it should be noted that the pressure column 33 under the multiple connecting plates 22 will first contact the upper end of the cable body 6, and then as the two electric push rods 21 continue to drive the electric heating plate 31, the multiple vertical blades 26 and the concave frame 29 to continue to move downward, the concave frame 29 will slide downward on the outer wall of the multiple connecting columns 30 and squeeze the multiple springs 32, so that the pressure columns 33 under the multiple connecting plates 22 can press the cable body 6, and the multiple connecting plates 22 and the multiple vertical blades 26 are staggered, which does not affect the movement of the multiple vertical blades 26).

[0039] At this time, as the electric slide rail 9 continues to move backward, the two heated triangular blades 17 will shear the outer sheaths on both sides of the cable body 6, and the heated multiple vertical blades 26 will cut the outer sheath on the upper part of the cable body 6 (it should be noted that the heated vertical blades 26 and triangular blades 17 can cut the thicker outer sheath of the cable body 6 over a long distance more smoothly and unimpeded, and will not cause wear to the conductor in the cable body 6), the outer sheaths on both sides of the cable body 6 and the upper outer sheath will be continuously cut open, and the pressure columns 33 under the multiple connecting plates 22 will continuously roll backward at the upper end of the cable body 6, and are always in a state of pressing the cable body 6 to prevent the cable body 6 from being displaced when the cable body 6 is sheared. When the electric slide rail 9 continues to move backward, it will also drive the two push blocks 23 inside it to push the support rod 24 backward. The support rod 24 will drive the two square rods 12 to slide backward in their corresponding square grooves 20 and squeeze the corresponding spring 19 until the support rod 24 is close to the front ends of the two baffles 10. At this time, the two triangular blades 17 and the multiple vertical blades 26 complete the transverse shearing of the outer sheath of the cable body 6.

[0040] Finally, the two electric push rods 13 drive the motors 18 and triangular blades 17 connected to them to move away from the cable body 6 until the tips of the two triangular blades 17 leave the two sides of the cable body 6, and then start the two motors 18 to drive the triangular blades 17 connected to them to rotate 90 degrees, and then drive the two triangular blades 17 to cut into the two sides of the cable body 6, and then start the electric slide rail 9. The two slides on the electric slide rail 9 can move along an elliptical path, so as to adapt to the sheath of the flat cable body 6 with an elliptical cross section. (It should be noted that the triangular blade 17 has two blade surfaces, see the specific reference Figure 2 , so that after the triangular blade 17 rotates ninety degrees, there is still a sharp blade facing the outer sheath to shear), then the multiple vertical blades 26 and the pressure columns 33 under the multiple connecting plates 22 move up and return to the original height, and then the electric slide rail 9 is driven forward by the linear slide 25. Since the two sides of the cable body 6 are cut open at this time, the outer sheath on the upper part of the cable body 6 is cut open in multiple places, and a surrounding area outside the cable body 6 is also cut open, the outer sheath will be separated from the conductor to a large extent. Then, when the electric slide rail 9 moves forward and drives the two triangular blades 17 to move forward together, the two triangular blades 17 will easily push the cut outer sheath away from the conductor, so that the flat cable body 6 is not only convenient to be cut to the required length, but also the outer sheath of the flat cable body 6 close to the cutting point and having a certain close fit with the conductor is also convenient to be sheared and separated, which brings convenience.

[0041] It should be noted that the portion of the triangular blade 17 close to the output shaft of the motor 18 is made of hard thermal insulation material, and the portion of the upper end of the electric heating plate 31 close to the telescopic axis of the electric push rod 21 is also made of hard thermal insulation material to prevent heat from causing damage to the motor 18 and the electric push rod 21. The hard thermal insulation material can be made of aluminum silicate fiber, which has good thermal insulation properties.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
