Description

Technical Field

[0001] The invention relates to the technical field of cable processing, and in particular to a multifunctional wire stripper for processing electric wires and cables. Background Art

[0002] Modern cables are usually composed of several basic parts, such as conductor, insulation layer, shielding layer (optional), and sheath. The conductor is the core of current or signal transmission, usually made of highly conductive metal materials (such as copper and aluminum); the insulation layer is wrapped around the outside of the conductor to prevent current leakage and short circuit, usually made of insulating materials such as rubber and plastic; the shielding layer is used to reduce electromagnetic interference and improve signal transmission quality; the sheath is the outermost protective layer, used to resist external factors such as mechanical damage and chemical corrosion.

[0003] In addition, the existing cables need to be cut and stripped in advance when they are processed and stripped. The patent name is "A wire stripper for cable processing" and the authorization announcement number is: CN110752558B. It is proposed in the patent that the existing design of the wire stripper needs to lift the left and right support frames back and forth when stripping and taking out the stripped cables, which is inconvenient to use. Moreover, when lifting and placing the next cable to be stripped, the cross-cutting knife will be lifted up as the upper support body is lifted. After the hot melt heating, there is still a relatively hot temperature. When placing the cable, the support body is lifted and lowered back and forth, which is a lot of work and causes soreness and fatigue of the arms. If the staff members are not careful and do not avoid it, they may easily burn their hands, which poses certain safety hazards. By providing corresponding "U"-shaped grooves on the left and right support frames in the support mechanism, when placing the wires and cables for stripping operations, it is only necessary to rotate the second gasket to the left support frame. By opening the "U" shaped groove above the "U" shaped groove on the frame, the wires and cables can be placed into the "U" shaped grooves on the left support frame and the right support frame. There is no need to lift and lower the supporting mechanism back and forth, which is easy to use and simple to operate. The cross-cutting mechanism in the above invention does not move when placing the cables, and the cross-cutting head is located above the cables in a normal state and does not tilt up, which reduces the probability of the staff touching the cross-cutting head when placing the cables, reduces safety hazards, and enhances safety of use. Although a corresponding "U" shaped groove is provided to solve the safety problems caused by cable stripping operations, the internal space of the "U" shaped groove is limited. In the case of limited space, cables that are too large or too small cannot be fixed and limited. In the case of inability to fix and limit, hot-melt cutting and stripping cannot be performed. For this reason, the present application proposes a multifunctional wire stripper for wire and cable processing. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1: Figure 1 As shown, the present application is a multifunctional wire stripper for wire and cable processing, including a support frame 100, a placement slot is opened on the outside of the support frame 100, a connecting support rod 101 is fixedly connected to the inside of the support frame 100, a plurality of damping hinge rings 102 are rotatably connected to the outside of the connecting support rod 101, an arc-shaped clamping arm 103 is fixedly connected to the outside of the damping hinge ring 102, a plurality of arc-shaped clamping arms 103 are in the shape of mutually interlocking clamping claws, the arc-shaped clamping arms 103 are arc-shaped, a soft heating plate 106 is connected to the arc-shaped inner side of the arc-shaped clamping arm 103, a plurality of positioning clamping hoops 104 are fixedly connected to the outer wall of the arc-shaped clamping arm 103, a positioning plug-in rod 105 is movably connected to the inner wall of the positioning clamping hoops 104, an expansion extrusion structure is installed on the arc-shaped inner wall of the arc-shaped clamping arm 103, and an arc-shaped portion 700 is integrally formed on the side of the support frame 100 close to the placement slot.

[0029] Specifically, during use, the staff will place the cables that need to be processed and stripped at the placement slot position opened on the outside of the support frame 100. The placement slot is a horizontal slot, supported by the support frame 100 at the bottom, and during the placement process, the cable can be placed in the placement slot or detached from the placement slot through the integrally formed arc portion 700. When placing the cable in the placement slot, a plurality of arc-shaped clamping arms 103 that are interlocked and shaped like clamping claws are separated, and the cable is placed between the plurality of clamping claws. After the cable is placed between the clamping claws, the plurality of arc-shaped clamping arms 103 are interlocked to form clamping claws to limit and fix the cable. At the same time, after the plurality of arc-shaped clamping arms 103 are interlocked and the cable located between the plurality of arc-shaped clamping arms 103 is limited, the positioning plug rod 105 is passed through the plurality of interlocking and staggered arc-shaped clamping arms 103. The positioning clamping hoop 104 on the outside of the clamping arm 103 prevents the multiple arc-shaped clamping arms 103 that are interlocked and limit the cable from separating, thereby preventing the arc-shaped clamping arms 103 from losing the limit on the cable. When multiple arc-shaped clamping arms 103 are used to clamp and limit the cable, the clamping and limiting of cables of different sizes can be adapted. In the case where multiple arc-shaped clamping arms 103 are interlocked to limit the cable, there are gaps between the multiple arc-shaped clamping arms 103, and after the locking and limiting is completed, the soft heating plate 106 is started to hot-melt the outside of the cable. After hot-melting, there are gaps between the multiple arc-shaped clamping arms 103, and the staff can perform cutting at the gaps. When it is necessary to cut the gaps at the multiple arc-shaped clamping arms 103, additional locking components can be used to connect two adjacent arc-shaped clamping arms 103, such as ropes or fixed mounting buckles.

[0030] like Figure 1-Figure 3 As shown, an upper support plate 800 is fixedly connected to the support frame 100, a sliding groove 801 is opened inside the upper support plate 800, two sliding rods 803 are fixedly connected inside the sliding groove 801, a moving seat 802 is slidably connected to the outside of the sliding rod 803, a lower connecting rod 806 is slidably connected at the center of the moving seat 802, an upper pressure plate 805 is fixedly connected to the lower connecting rod 806, a cutting knife 807 is fixedly connected to the bottom of the lower connecting rod 806, and two springs 804 are fixedly connected to the outer wall of the upper pressure plate 805.

[0031] Specifically, during use, after the cable is limited and hot-melted, the user can hold the upper pressure plate 805 and slide it on the sliding rod 803. After adjusting the cutting knife 807 to a suitable position, the upper pressure plate 805 is used to press the cutting knife 807 downward, thereby cutting the cable with the cutting knife 807. When pressing downward, the upper pressure plate 805 squeezes the spring 804, causing the spring 804 to produce a compression deformation. After the spring 804 produces a compression deformation and the upper pressure plate 805 loses the downward pressure of the staff, the spring 804 will rebound. When the spring 804 rebounds, the cutting knife 807 can be restored to its original position.

[0032] Furthermore, the outer walls on both sides of the movable seat 802 are fixedly connected with the limiting grooves 900, and the inner wall of the sliding groove 801 is provided with two limiting slide blocks 901, and the limiting grooves 900 are slidably connected to the inside of the limiting slide block 901. When the movable seat 802 slides inside the sliding groove 801, it slides inside the limiting slide block 901 through the limiting grooves 900, and cooperates with the sliding rod 803 to ensure the stability of the movable seat 802 when sliding inside the sliding groove 801.

[0033] Furthermore, during the cutting process, not only can cables of different shapes and sizes be squeezed and limited, but the cables can also be cut horizontally or stripped vertically. When stripping vertically, only the corresponding tool needs to be replaced to complete the corresponding cutting and stripping, thereby completing the multifunctional stripping of cables and wires.

[0034] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to the prior art, in this embodiment, the user can place the cable between multiple arc-shaped clamping arms 103. After placing the cable between multiple arc-shaped clamping arms 103, the multiple arc-shaped clamping arms 103 are pressed toward the cable position, and the inner arc-shaped edges of the arc-shaped clamping arms 103 are adapted to the shape of the cable. After adapting to the shape of the cable, the arc-shaped clamping arms 103 of the pressed cable are clamped and limited by multiple positioning plug-in rods 105, thereby realizing the use of multiple arc-shaped clamping arms 103 to clamp and limit cables of different sizes, adapting to the processing, cutting and stripping of different cables.

[0035] Embodiment 2: Considering that different cables have different thicknesses during use, although the arc-shaped edge of the arc-shaped clamping arm 103 can partially clamp the cable, and multiple arc-shaped clamping arms 103 are used to clamp and limit the cable, after the clamping and limiting is completed, the soft heating sheet 106 located on the arc-shaped side wall of the arc-shaped clamping arm 103 cannot be well attached to the outer wall of the cable for hot-melt treatment. In view of the above technical problems, the present application proposes an expansion extrusion structure to solve the above technical problems, specifically:

[0036] like Figure 1-Figure 5 As shown, Figure 4 It is an expansion state diagram of the expansion extrusion bladder 204, and the arc-shaped clamping arm 103 is not completely clamped. The expansion extrusion structure includes the expansion extrusion bladder 204, and the expansion extrusion bladder 204 is fixedly connected to the arc-shaped inner wall of the arc-shaped clamping arm 103, and the expansion extrusion bladder 204 is located between the arc-shaped clamping arm 103 and the soft heating plate 106. The outer wall surface of the support frame 100 is fixedly connected to a two-way air pump 200, and the air outlet of the two-way air pump 200 is connected to a diverter box 201. A plurality of first electrically controlled valves 202 are installed on the outside of the diverter box 201, and the air outlet of the first electrically controlled valve 202 is connected to a soft conveying pipe 203. The end of the soft conveying pipe 203 away from the first electrically controlled valve 202 passes through the outer wall of the arc-shaped clamping arm 103 and is connected to the expansion extrusion bladder 204.

[0037] Specifically, in the expansion and extrusion structure, the staff starts the two-way air pump 200 to continuously inject gas into the shunt box 201. After continuously injecting gas into the shunt box 201, the first electric-controlled valve 202 connected to the compression cable expansion and extrusion sac 204 can be opened. After the first electric-controlled valve 202 is opened, the gas inside the shunt box 201 will be continuously transported to the inside of the soft delivery tube 203. After the gas continues to enter the soft delivery tube 203, the soft delivery tube 203 will continuously transport the gas to the inside of the expansion and extrusion sac 204. When the gas is transported to the inside of the expansion and extrusion sac 204, the expansion The expansion and squeezing bladder 204 will expand, and when expanding, it will drive the soft heating plate 106 to gradually fit the outer wall of the cable inside the arc-shaped clamping arm 103. When the expansion and squeezing bladder 204 expands, it can not only drive the soft heating plate 106 to fit more closely to the outer wall of the cable, so that the soft heating plate 106 can better achieve the hot-melt effect on the cable, but also further increase the clamping stability of the cable when multiple arc-shaped clamping arms 103 completely clamp the cable. When exhausting, an electrically controlled exhaust valve is installed on the outside of the diverter box 201 to discharge the gas to the outside.

[0038] Furthermore, when the expansion and extrusion bladder 204 drives the soft heating plate 106 to completely fit the outer wall of the cable, the air inside the expansion and extrusion bladder 204 can also be heated in the process of the soft heating plate 106 fitting the cable and generating heat. In the process of heating the air inside the expansion and extrusion bladder 204, the air inside the expansion and extrusion bladder 204 will expand, further ensuring the expansion degree of the expansion and extrusion bladder 204, and enhancing the expansion and extrusion bladder 204 to drive the soft heating plate 106 to fit the cable.

[0039] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment one, in the present embodiment, by injecting gas into the interior of the expansion and extrusion bladder 204, the expansion and extrusion bladder 204 is expanded. When the expansion and extrusion bladder 204 is expanded, the soft heating sheet 106 can be driven to completely fit the outer wall of the cable, thereby fully fitting the outer walls of cables of different diameters, thereby achieving full hot melting of the outer walls of different cables, and when the soft heating sheet 106 fully hot melts the cable, the air inside the expansion and extrusion bladder 204 is heated, so that the expansion and extrusion bladder 204 is fully expanded, so that the soft heating sheet 106 always fits the outer wall of the cable during the hot melting process.

[0040] Embodiment 3: Considering that the hot-melting position of the soft heating sheet 106 to the cable is limited during use, and the hot-melting position of the soft heating sheet 106 cannot be directly cut by the cutting knife 807 due to the presence of the arc-shaped clamping arm 103, the present application proposes the following technical solutions to solve the above technical problems, specifically:

[0041] like Figure 6-Figure 8 As shown, during use, when the cable needs to be hot-melted, gas is first filled into the expansion and extrusion sac 204 to expand the expansion and extrusion sac 204. When the expansion and extrusion sac 204 is expanded, the soft heating plate 106 is driven to fit the outer wall of the cable. When the expansion and extrusion sac 204 is not fully fitted, the second electric control valve 301 is opened to divert the gas inside the soft delivery tube 203 into the outer delivery tube 300, and the gas is transported into the side extension sac 302 through the outer delivery tube 300 and the second electric control valve 301. When the gas enters the side extension sac 302, the side extension sac 302 can be expanded. When the side extension sac 302 expands, it can drive the soft heating plate 106 to move laterally. When the lateral displacement occurs, the cable at one side of the arc-shaped clamping arm 103 can be hot-melted. After the hot-melting of one side is completed, the gas inside the side extension sac 302 is released to cause the side extension sac 302 to condense. When the side extension sac 302 condenses, the side extension sac 302 will drive the soft heating plate 106 to return to its original position, thereby vacating the position where the hot-melt has been performed. After the hot-melt position is vacated, the user can directly cut the vacated hot-melt position.

[0042] like Figure 7-Figure 8 As shown, the outside of the expansion and extrusion bladder 204 is fixedly connected with a soft heat-insulating cotton 500 , and the soft heat-insulating cotton 500 is bonded to a side of the soft heating plate 106 close to the expansion and extrusion bladder 204 .

[0043] Specifically, by providing the soft heat-insulating cotton 500, the high temperature generated by the soft heating plate 106 can be prevented from directly contacting the arc-shaped clamping arm 103, thereby preventing the expansion and extrusion bladder 204 and the side extension bladder 302 from being damaged when the expansion and extrusion bladder 204 is used for a long time.

[0044] like Figure 7-Figure 8 As shown, micropores 600 are formed on the outer walls of the side extension bladder 302 , the soft heat insulating cotton 500 and the soft heating plate 106 .

[0045] Specifically, the micropores 600 located outside the side extension bladder 302 will be in a closed state under normal conditions due to the elasticity of the side extension bladder 302 itself, and when the side extension bladder 302 expands, the side extension bladder 302 itself expands and extends. When the side extension bladder 302 expands and extends, the multiple micropores 600 located outside the side extension bladder 302 will gradually open. When the multiple micropores 600 located outside the side extension bladder 302 are in an open state, the air inside the side extension bladder 302 will pass through the micropores 600 outside the soft heating plate 106, and then be heated by the soft heating plate 106 and ejected to form a hot air effect, so that the hot air contacts the outer wall of the cable through the micropores 600, thereby accelerating the hot melting effect of the cable.

[0046] The technical solution in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: relative to embodiment 2, in this embodiment, through the setting of the side extension sac 302, the soft heating plate 106 can be driven to move laterally during the hot melting process. When the soft heating plate 106 moves laterally, the outer wall of the cable in the remaining part can be hot-melted to melt the outer wall of the cable in the remaining part. After the cable in the remaining part is melted, the gas inside the side extension sac 302 is discharged, thereby leaving space for the cable in the remaining part, thereby facilitating the staff to directly cut the cable in the remaining part.

[0047] Embodiment 4: Considering that during use, the side extension sac 302 can drive the soft heating sheet 106 to heat-melt the spare part of the cable, and in the process of hot-melting the spare part of the cable, the side extension sac 302 has no external support after expansion. When the side extension sac 302 expands and has no support, the soft heating sheet 106 cannot be well attached to the outer wall of the cable. In view of the above technical problems, the present application proposes the following technical solutions, specifically:

[0048] like Fig. 9As shown, a portion of the side extension sac 302 is fixedly connected to a plurality of magnetic adsorption blocks 400, and another portion of the side extension sac 302 is installed with an iron adsorption plate. The side extension sac 302 with the magnetic adsorption blocks 400 installed therein is arranged adjacent to the side extension sac 302 with the iron adsorption plate installed therein.

[0049] Specifically, during use, after the staff uses multiple arc-shaped clamping arms 103 to limit the cable, and uses multiple expansion and extrusion capsules 204 to limit the cable, multiple soft heating plates 106 are driven by the expansion and extrusion capsules 204 to fit the cable. At the same time, when the side of the cable needs to be hot-melted, the gas is diverted to the inside of the side extension capsule 302, and the soft heating plates 106 are driven by the side extension capsule 302 to hot-melt the cable in the vacant position. During the hot-melt treatment of the cable in the vacant position, because the side of the side extension capsule 302 away from the soft heating plate 106 does not have any supporting objects and limiting objects, and because the soft heating plate 106 cannot fit well to the outer wall of the cable after the side extension capsule 302 expands, during the expansion of the side extension capsule 302, two side extension capsules 302 close to each other are installed with The adsorption structure includes multiple side extension capsules 302 that are close to each other, a part of which is equipped with multiple magnetic adsorption blocks 400, and another part of which is equipped with an iron adsorption plate. When the side extension capsules 302 gradually expand, the magnetic adsorption blocks 400 and the iron adsorption plates inside the side extension capsules 302 that are close to each other can produce an adsorption effect on each other. When the adsorption effect is produced, the side extension capsules 302 can be pulled closer to the position of the arc-shaped clamping arms 103 of each other, so that the side extension capsules 302 located on both sides of the cable gradually approach each other under the action of magnetic adsorption, forming a limiting adsorption effect on the side extension capsules 302, so that the side extension capsules 302 can always drive the soft heating plate 106 to fit the outer wall of the cable when driving the soft heating plate 106 to move sideways, and perform a tighter fitting hot-melt treatment on the outer wall of the cable.

[0050] like Fig. 9 As shown, multiple magnetic adsorption blocks 400 and multiple iron adsorption plates installed inside the side extension sac 302 are staggered with each other. Through the staggered setting, the magnetic adsorption blocks 400 and the iron adsorption plates can be close to each other and produce mutual adsorption effects. The staggered adsorption will drive the side extension sac 302 to completely fit the outer wall of the cable, thereby reducing the phenomenon of warping caused by the lack of adsorption points on one side.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
