Description

Technical Field

[0001] This invention relates to the field of power equipment, and more specifically to a cable straightening structure and a straightening method thereof. Background Technology

[0002] When performing power system work, it is often necessary to perform a series of operations on the work site, such as stripping, straightening, and crimping wires and cables. Operators often use tools such as electrician's pliers and vise pliers to strip and straighten the wires, which is quite troublesome.

[0003] Chinese patent CN109759525B discloses a multi-functional cable straightener, which straightens cables by setting a wire-pressing wheel on the clamp body and a wire-stripping device on the jaws to strip the cables. It integrates multiple functions, allowing operators to quickly and conveniently straighten and strip cables.

[0004] However, the above invention requires multiple steps to strip and straighten the wire, and the operation is relatively complicated; its wire clamping wheel is located between the main clamping lip and the secondary clamping lip, which makes it inconvenient to straighten longer wires.

[0005] Based on this, the present invention provides a cable straightening structure and a straightening method that facilitates cable straightening, in order to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the problems of existing wire stripping and straightening processes requiring multiple steps, complex procedures, and inconvenience when straightening long wires, this invention provides a cable straightening structure that facilitates straightening.

[0007] This invention proposes a cable straightening structure, comprising a first base plate and a second base plate;

[0008] The first base plate is equipped with a stripping assembly for stripping the cable sheath and a straightening assembly for straightening the cable. The stripping assembly is connected to the pressing and cutting assembly and the second base plate.

[0009] The wire stripping assembly includes a blade assembly and a holding assembly; the blade assembly is connected to the bottom of the first base plate and the second base plate, and the holding assembly is connected to the blade assembly.

[0010] Furthermore, the blade assembly includes clamping plates, clamping blocks, first guide holes, sliding grooves, blades, and blade screws. The bottoms of the first base plate and the second base plate are each rotatably connected to the top of a set of clamping plates, and the two sets of clamping plates are symmetrically distributed. A set of clamping blocks is fixedly connected to the top of each clamping plate. At least one set of first guide holes is provided on the side wall of each clamping block. A sliding groove is provided on the inner side wall of each clamping block, and the inner wall of each sliding groove is respectively limited and slidably connected to the side wall of a set of blades. The side wall of each clamping block is respectively threadedly connected to the side wall of a set of blade screws, and the inner end of each blade screw is rotatably connected to the outer end of the blade.

[0011] Furthermore, the gripping assembly includes a handle, a spring, and a limiting plate; a set of handles is fixedly connected to the left side wall of each clamp; the two ends of the spring are respectively connected to the inner side wall of the two sets of handles.

[0012] Furthermore, the straightening assembly includes base plate screws, straightening rollers, and a second guide hole; at least one set of base plate screws is installed on the side wall of the first base plate, the rear ends of the base plate screws all pass through the side wall of the first base plate and connect to the side wall of the second base plate, the side wall of the base plate screws is rotatably connected to the side wall of the first base plate, and the side wall of the base plate screws is threadedly connected to the side wall of the second base plate; multiple sets of straightening rollers are rotatably connected to the top of both the first and second base plates; at least one set of second guide holes is provided on the right side wall of both the first and second base plates.

[0013] Furthermore, the pressing and shearing assembly includes a shearing port and a pressing port; both sets of clamps have shearing ports and pressing ports at their inner ends, and the shearing ports and pressing ports are symmetrically distributed.

[0014] Furthermore, the blade is provided with a scale, and each clamping block is provided with a viewing window that is connected to the slide groove. The viewing window and the scale on the blade are at the same height.

[0015] Furthermore, the right end of each handle is fixedly connected to the lower end of the left side wall of the clamping block on the same side.

[0016] Furthermore, the two ends of the spring are respectively fixedly connected to the inner sidewalls of the two sets of handles.

[0017] Furthermore, the straightening wheels mounted on the first base plate and the straightening wheels mounted on the second base plate are arranged alternately.

[0018] To better achieve the objectives of this invention, the present invention also provides a method for straightening a cable processing structure that facilitates straightening, comprising the following steps:

[0019] Step 1: Pass the cable through the second guide hole of the straightening assembly and through the straightening rollers; rotate the adjusting base plate screw to bring the first base plate and the second base plate closer together, so that the inner side wall of the straightening rollers fits against the side wall of the cable.

[0020] Step 2: Pass the wire end through the first guide hole on the clamping block of the stripping assembly's blade assembly. Rotate the blade screw according to the thickness of the wire, so that the inner end of the blade screw drives the blade to slide along the groove. After the blade is adjusted to the appropriate position, grip the handle of the holding assembly to rotate the two sets of clamping plates inward, thereby rotating the clamping block inward, so that the blade squeezes and cuts the cable sheath. At this time, pull the cable to tear off the sheath, and straighten the wire end by squeezing it through the straightening wheel.

[0021] Step 3: When cutting the cable, insert the cable into the cutting slot, grip the handle tightly, and rotate the clamp inward to cut the cable. When crimping the cable lugs, insert the end of the cable with the lugs on into the pressing slot, grip the handle tightly, and rotate the clamp inward to press and secure it. The distance between the first and second base plates can be adjusted by turning the base plate screws according to the cable thickness. Adjusting the distance between the two sets of clamps adjusts the size of the cutting and pressing slots. Compared with the prior art, the beneficial effects of this invention are:

[0022] 1. By adjusting the blade screw, the blade can be adapted to cables of different thicknesses; by passing the cable through the straightening assembly first and then through the first guide hole, the stripping and straightening can be completed simultaneously by pulling out the cable during stripping, thereby saving operation time.

[0023] 2. This invention allows the straightening rollers to fit the cable by adjusting the base plate screws. Multiple sets of straightening rollers provide better stability for longer cables and facilitate straightening.

[0024] 3. This invention cuts the cable by inserting it into the cutting opening and gripping the handle to rotate the clamp inward. When a wire lug is needed, the end of the cable with the lug attached is inserted into the pressing opening, and the handle is gripped to press and secure it. The distance between the first and second base plates can be adjusted by rotating the base plate screws according to the cable thickness. The size of the cutting and pressing openings can be adjusted by adjusting the distance between the two sets of clamps, thus completing the straightening, cutting, and wire lug adjustment functions in one go, which is convenient and quick.

[0037] Example 1

[0038] Please refer to the instruction manual appendix. Figure 1-7 A cable straightening structure includes a first base plate 1 and a second base plate 5.

[0039] The first base plate 1 is equipped with a stripping assembly 2 for stripping the cable sheath and a straightening assembly 3 for straightening the cable. The stripping assembly 2 is connected to the pressing and cutting assembly 4 and the second base plate 5.

[0040] The wire stripping assembly 2 includes a blade assembly 21 and a holding assembly 22; the blade assembly 21 is connected to the bottom of the first base plate 1 and the second base plate 5, and the holding assembly 22 is connected to the blade assembly 21.

[0041] The blade assembly 21 includes a clamping plate 211, a clamping block 212, a first guide hole 213, a sliding groove 214, a blade 215, and a blade screw 216. The bottom of the first base plate 1 and the second base plate 5 are each rotatably connected to the top of a set of clamping plates 211, and the two sets of clamping plates 211 are symmetrically distributed. A set of clamping blocks 212 is fixedly connected to the top of each clamping plate 211. At least one set of first guide holes 213 are opened on the side wall of each clamping block 212. A sliding groove 214 is opened on the inner side wall of each clamping block 212, and the inner wall of each sliding groove 214 is respectively limited and slidably connected to the side wall of a set of blades 215. The side wall of each clamping block 212 is respectively threadedly connected to the side wall of a set of blade screws 216, and the inner end of each blade screw 216 is rotatably connected to the outer end of each blade 215.

[0042] Preferably, the blade 215 is provided with a scale, and each clamping block 212 is provided with a viewing window 217 and the viewing window 217 is connected to the slide groove 214. The viewing window 217 and the scale on the blade 215 are at the same height.

[0043] The gripping assembly 22 includes a handle 221, a spring 222, and a limiting plate 223; a set of handles 221 are fixedly connected to the left side wall of the clamping plate 211; the two ends of the spring 222 are respectively connected to the inner side wall of the two sets of handles 221.

[0044] Preferably, the right end of each handle 221 is fixedly connected to the lower end of the left side wall of the clamping block 212 on the same side.

[0045] Preferably, the two ends of the spring 222 are fixedly connected to the inner sidewalls of the two sets of handles 221 respectively.

[0046] In operation, the wire to be straightened is inserted into the inlet of the straightening assembly 3 and passes through the straightening assembly 3. Then, the straightening assembly 3 is adjusted to fit the wire. Next, the wire end is passed through the first guide hole 213 on the clamping block 212 of the blade assembly 21 of the stripping assembly 2. The blade screw 216 is rotated according to the thickness of the wire, so that the inner end of the blade screw 216 drives the blade 215 to slide along the slide groove 214. After the blade 215 is adjusted to a suitable position, the handle 221 of the holding assembly 22 is gripped, causing the two sets of clamping plates 211 to turn inward. The rotation causes the clamping block 212 to rotate inward, causing the blade 215 to squeeze and cut the cable sheath. At this time, the cable is pulled, the sheath is torn off, and the end of the cable passes through the straightening component 3 and is pulled out from the inlet end, thereby straightening the straightening component 3. By adjusting the blade screw 216, the blade 215 can be adapted to cables of different thicknesses. By passing the cable through the straightening component 3 first and then through the first guide hole 213, the stripping and straightening can be completed simultaneously by pulling out the cable, thus saving operation time.

The side wall of the base plate screws 31 is rotatably connected to the side wall of the first base plate 1, and the side wall of the base plate screws 31 is threadedly connected to the side wall of the second base plate 5; multiple sets of straightening wheels 32 are rotatably connected to the top of both the first base plate 1 and the second base plate 5; at least one set of second guide holes 33 are provided on the right side wall of both the first base plate 1 and the second base plate 5.

[0049] Preferably, the straightening rollers 32 installed on the first base plate 1 and the straightening rollers 32 installed on the second base plate 5 are arranged alternately.

[0050] When the present invention is in operation, the cable is passed through the second guide hole 33 of the straightening assembly 3 and through the straightening rollers 32; the adjusting base plate screw 31 is rotated to bring the first base plate 1 and the second base plate 5 closer together, so that the inner side wall of the straightening roller 32 is in contact with the side wall of the cable. When stripping the cable, the cable is pulled out and straightened by the pressure of the straightening roller 32; by adjusting the base plate screw 31, the straightening roller 32 can be made to fit the cable. Multiple sets of straightening rollers 32 have a better stabilizing effect on longer cables and facilitate straightening.
