Description

Technical Field

[0001] The invention belongs to the technical field of copper-silver alloy wires, in particular to a copper-silver alloy wire with a wire stripping mechanism. Background Art

[0002] Copper-silver alloy refers to a silver alloy with copper as the main alloying element. In order to improve the performance, nickel, beryllium, lithium, vanadium and other elements are often added. It is mainly used as electrical contact materials and brazing materials. The hardness of copper-silver alloy is higher than that of silver. Its electrical and thermal conductivity are better than other alloys. It is also inexpensive and widely used. The copper content in copper-silver alloy is different and the color is also different, ranging from silver white to rose red to red. It has fine crystals, no brittleness, and better wear resistance than pure silver. Its outstanding feature is its strong resistance to sulfides. Copper-silver alloy wire is generally used as a cable for transmitting power. The cable includes a built-in alloy conductive core and an insulating sheath covering its surface.

[0003] When connecting the ends of the existing copper-silver alloy wires, it is necessary to cut off the insulating sleeve covering the outside to expose the copper-silver alloy wire inside for connection and fixation. Currently, most construction workers use a manual knife to cut along the outer circle of the insulating sleeve. This method is very dependent on the cutting proficiency of the construction workers and has poor stability. It is easy to cause excessive cutting force to damage the internal copper-silver alloy wire. Some construction workers use fire to burn the ends of the copper-silver alloy wires to soften the insulating sleeve at the ends and expose the copper-silver alloy wires for connection and fixation. However, this method will cause the outer area of ​​the copper-silver alloy wire to be charred, which will easily cause the insulating sleeve near the end to soften, affecting the service life.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown, the annular rotating block 4 is provided with a symmetrically distributed arc-shaped extrusion cavity 41 inside, the inner surface of the annular rotating block 4 is provided with a first through groove 42, one end of the first through groove 42 is connected to the inner wall of the inner side of the arc-shaped extrusion cavity 41, the outer surface of the annular rotating block 4 is provided with a second through groove 43, one end of the second through groove 43 is connected to the outer inner wall of the arc-shaped extrusion cavity 41, and the inner wall of the cutting sleeve 2 is fixedly connected with a symmetrically distributed guide block 44, the cross section of the guide block 44 is L-shaped, and the guide block 44 is A rectangular guide rod 45 is movably sleeved on the inner wall, one end of the rectangular guide rod 45 is fixedly connected to a cutting knife 46, the other end of the rectangular guide rod 45 passes through the first through slot 42 and extends to the interior of the arc-shaped extrusion cavity 41, the other end of the rectangular guide rod 45 is fixedly connected to a positioning ball 47, the outer surface of the rectangular guide rod 45 is movably sleeved with a movable ball 48, the outer surface of the rectangular guide rod 45 is movably sleeved with a return spring 49, one end of the return spring 49 is fixedly connected to the outer surface of the movable ball 48, and the other end of the return spring 49 is fixedly connected to the outer surface of the positioning ball 47, a third annular groove 410 is provided on the inner wall of the cutting sleeve 2, the inner wall of the third annular groove 410 is slidably connected to a third arc-shaped slider 411 distributed in an annular array, the inner side surface of the third arc-shaped slider 411 is fixedly connected to a connecting block 412, one end of each of the connecting blocks 412 is fixedly connected to the lower surface of the annular rotating block 4, the outer surface of the cutting sleeve 2 is provided with symmetrically distributed rotating grooves 413, and the outer surface of the annular rotating block 4 is fixedly connected to A driving rod 414, one end of which passes through the rotating groove 413 and extends to the outer surface of the cutting sleeve 2, an outer surface of the positioning ball 47 is fixedly connected with an adjusting screw 415, one end of which passes through the second through groove 43 and extends to the outer surface of the cutting sleeve 2, an outer surface of the adjusting screw 415 is threadedly connected with a threaded adjusting ring 416, one side surface of the threaded adjusting ring 416 contacts the outer surface of the cutting sleeve 2, and the outer surface of the cutting sleeve 2 is fixedly connected with a symmetrically distributed scale 417.

[0039] The above scheme is adopted: by setting the rectangular guide rod 45 in a square strip shape, it is convenient for the guide block 44 to limit the position, so as to prevent the cutting knife 46 from being offset by angle due to its rotation, thereby causing an uneven incision. The scale 417 is used to facilitate the observation of the moving adjustment distance of the threaded adjustment ring 416, and the rotating groove 413 plays a role in guiding and limiting the rotation stroke of the driving rod 414. The driving rod 414 drives the annular rotating block 4 to rotate. The rotation of the annular rotating block 4 squeezes the positioning ball 47 through the arc-shaped extrusion cavity 41, so that the adjusting screw 415 drives the rectangular guide rod 45 through the positioning ball 47 The cutting knife 46 moves toward the inner side of the annular rotating block 4, so that the cutting end of the cutting knife 46 is inserted into the insulating sleeve. Finally, the fixation of the cutting sleeve 2 is loosened, and the driving rod 414 is continuously moved. Due to the limitation of the threaded adjustment ring 416, the cutting sleeve 2 is rotated through the cooperation of the first arc-shaped slider 32 and the first arc-shaped slide groove, thereby realizing the rotational cutting of the insulating sleeve. After one rotation, the cutting is completed. At this time, the driving rod 414 is rotated in the opposite direction. After the elastic force of the reset spring 49 and the active ball 48 drive the adjusting screw 415 to reset, the threaded adjustment ring 416 is rotated clockwise until it contacts the cutting sleeve 2.

[0040] The working principle and use process of the present invention:

[0041] Step 1: Pass the copper-silver alloy wire body 1 through the cutting sleeve 2 from bottom to top, and move the part to be cut to the middle of the cutting sleeve 2. At this time, turn the driving handles 317 at the upper and lower ends clockwise in sequence. The rotation of the driving handle 317 drives the screw rod 316 to rotate. The rotation of the screw rod 316 drives the threaded block 313 to move. The movement of the threaded block 313 drives the driving block 312 to rotate in a circle through the pin shaft. The rotation of the driving block 312 drives the locking ring 36 to rotate and makes its second positioning rod 314 cooperate with the positioning block 315 to rotate at an angle.

[0042] Step 2: The locking ring 36 rotates stably through the cooperation of the positioning ring 35, the second annular slide groove 33 and the second arc-shaped slider 34. The locking ring 36 rotates stably through the cooperation of the swing sleeve 38 to drive the swing rod 39 and the first positioning rod 311 to rotate. The swing rod 39 rotates through the limit of the swing sleeve 38 so that the swing arc clamp 310 at one end contacts the outer surface of the copper-silver alloy wire body 1 and clamps and fixes it.

[0043] Step three, since the cutting port of the cutting knife 46 is in the same horizontal plane as the inner wall of the positioning ring 35, the inner diameter of the positioning ring 35 minus the inner diameter of the insulating sleeve on the surface of the copper-silver alloy wire body 1 is equal to the distance that the cutting knife 46 needs to move, and then the threaded adjustment ring 416 is rotated counterclockwise according to the value on the scale 417 to move it to the value of the distance that the cutting knife 46 needs to move, and then the cutting sleeve 2 is fixed with one hand to prevent it from rotating, and the driving rod 414 is moved with the other hand so that the driving rod 414 drives the annular rotating block 4 to rotate, and the annular rotating block 4 is positioned and rotated by the cooperation of the third annular slide groove 410, the third arc-shaped slider 411 and the connecting block 412;

[0044] Step 4: The annular rotating block 4 rotates because the rectangular guide rod 45 is limited by the guide block 44, so that when it rotates, the positioning ball 47 is squeezed through the arc-shaped extrusion cavity 41, so that the adjusting screw 415 drives the rectangular guide rod 45 and the cutting knife 46 to move to the inside of the annular rotating block 4 through the positioning ball 47. When the annular rotating block 4 rotates, the threaded adjustment ring 416 on the adjusting screw 415 moves to the contact limit with the outer side of the cutting sleeve ring, and at this time, the cutting knife 46 moves and is inserted into the outer insulating sleeve of the copper-silver alloy wire body 1;

[0045] Step five, at this time, release the fixation on the cutting sleeve 2, and continue to move the driving rod 414. Due to the limitation of the threaded adjustment ring 416, the cutting sleeve 2 is rotated through the cooperation of the first arc-shaped slider 32 and the first arc-shaped slide groove, thereby realizing the rotational cutting of the insulating sleeve. After one rotation and cutting, the annular rotating block 4 is rotated in the opposite direction by the driving rod 414, and the adjusting screw 415 is driven to reset and move through the elastic force of the movable ball 48 and the reset spring 49, so that its cutting knife 46 is reset and moved to disengage from the insulating sleeve. At this time, the driving handle 317 at the lower end is rotated counterclockwise, so that its arc surface clamping block 310 cancels the limitation on the lower end of the copper-silver alloy wire body 1, and finally the cutting sleeve 2 is pulled upward. Since the cut insulating sleeve is fixed by the arc surface clamping block 310 at the upper end, the cut insulating sleeve is driven to separate from the copper-silver alloy wire body 1, so that it is exposed to the outside, which is convenient for wiring and fixing.
