Description

Technical Field

[0001] This utility model relates to a wire stripping tool, and more particularly to a wire stripping tool with a long service life and a wire stripping machine having the tool. Background Technology

[0002] A wire stripper is a machine that peels the plastic sheath from the metal core of electrical wires. It typically consists of a stripping blade and other conveying and transmission structures. The conveying and transmission structures grip and transport the wire / cable, while the rotating blades peel away the outer sheath, ultimately revealing the metal core. Compared to manual stripping, wire strippers are more efficient, more precise, and easier to operate. Most existing wire strippers use rotating, ring-shaped blades. However, single-blade strippers bear significant pressure when cutting the wire sheath, leading to wear and chipping after prolonged use. Utility Model Content

[0003] Therefore, it is necessary to provide a wire stripping tool with a long service life to address the shortcomings of existing technologies.

[0004] A long-life wire stripping tool includes a tool holder, a tool support, and multiple blades. The tool holder comprises two sets of base plates and two sets of connecting frames. The two sets of base plates are horizontally spaced apart, and both sets of connecting frames are n-shaped, spanning between the two sets of base plates with their ends fixedly connected to the tops of the two sets of base plates. The tool support has an n-shaped cross-section and is provided with a slot at the bottom and both ends. The tool support is mounted on the tool holder and located inside the connecting frames. Multiple blades are sequentially and spaced apart within the slots of the tool support, with the lowest points of the blades arranged in a sequentially ascending order.

[0005] Furthermore, the tool holder also includes a rotating shaft bracket and an adjusting bracket, and a limiting adjusting rod is provided on the outer side of the tool holder. Both the rotating shaft bracket and the adjusting bracket are fixedly mounted on the tool holder and located on the outer side of the tool holder. The rotating shaft bracket has a rotating shaft hole, and the adjusting bracket has an adjusting hole. The rotating shaft of the blade at one end of the tool holder extends through and passes through the rotating shaft hole on the rotating shaft bracket, allowing for rotational adjustment. The limiting adjusting rod is located on the outer side of the other end of the tool holder, and it also slides through the adjusting hole of the adjusting bracket.

[0006] Furthermore, the multiple blades on the tool holder are all synchronously powered, and the diameters of these multiple blades are arranged in descending order.

[0007] Furthermore, the upper end of the tool holder is also provided with an adjustment handle.

[0008] In addition, this utility model also provides a wire stripping machine.

[0009] A wire stripping machine includes a base, a conveyor frame, multiple sets of drive rollers, and wire stripping blades. The conveyor frame is fixedly mounted on the base and has a U-shaped cross-section. It has conveying grooves open at the top and both ends. The multiple sets of drive rollers are sequentially and spaced apart within the conveying grooves of the conveyor frame. The wire stripping blades are mounted on the base and located above the conveyor frame. These wire stripping blades are long-life wire stripping blades and include a blade holder, a blade support, and multiple blades. The blade holder includes two sets of base plates and two sets of connecting frames. The two sets of base plates are horizontally spaced apart. Both sets of connecting frames have an "n"-shaped structure, spanning between the two sets of base plates, with their ends fixedly connected to the tops of the two sets of base plates. The blade support has an "n"-shaped cross-section and has blade slots open at the bottom and both ends. The blade support is mounted on the blade holder and located inside the connecting frames. The multiple blades are sequentially and spaced apart within the blade slots of the blade support, with the lowest points of the multiple blades arranged in a sequentially ascending order.

[0010] Furthermore, the tool holder also includes a rotating shaft bracket and an adjusting bracket, and a limiting adjusting rod is provided on the outer side of the tool holder. Both the rotating shaft bracket and the adjusting bracket are fixedly mounted on the tool holder and located on the outer side of the tool holder. The rotating shaft bracket has a rotating shaft hole, and the adjusting bracket has an adjusting hole. The rotating shaft of the blade at one end of the tool holder extends through and passes through the rotating shaft hole on the rotating shaft bracket, allowing for rotational adjustment. The limiting adjusting rod is located on the outer side of the other end of the tool holder, and it also slides through the adjusting hole of the adjusting bracket.

[0011] Furthermore, the multiple blades on the tool holder are all synchronously powered, and the diameters of these multiple blades are arranged in descending order.

[0012] Furthermore, the upper end of the tool holder is also provided with an adjustment handle.

[0013] Furthermore, the wire stripping machine also includes a lifting adjustment rod and an auxiliary slide rod, with corresponding sliding holes provided on the base plate. Both the lifting adjustment rod and the auxiliary slide rod are fixedly mounted on the base. The upper end of the lifting adjustment rod is fixedly connected to the bottom of the base plate and can drive the wire stripping cutter to move up and down. The auxiliary slide rod passes through the sliding holes on the base plate to balance and limit the movement of the wire stripping cutter.

[0014] Furthermore, the wire stripping machine also includes a conveyor motor and a wire stripping motor. The conveyor motor is mounted on the base and is poweredly connected to multiple transmission rollers, while the wire stripping motor is mounted on the base plate and is poweredly connected to multiple blades.

[0015] In summary, the beneficial effects of this utility model's long-life wire stripping tool and wire stripping machine are as follows: By designing multiple blades on the tool, with the blade edges arranged in order of depth, the wire insulation can be cut sequentially from shallow to deep during the stripping process. This reduces the cutting pressure borne by a single blade, thereby extending the service life of the wire stripping tool. Furthermore, the adjustable structure of the wire stripping tool and the stripping machine allows it to strip wires and cables of different diameters and insulation thicknesses, greatly expanding the applicability of the wire stripping machine. This utility model is highly practical and has significant potential for widespread application. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a wire stripping machine 100, which includes a base 10, a conveyor frame 20, multiple sets of drive rollers 30, and a wire stripping cutter 40. The conveyor frame 20 is fixedly mounted on the base 10. The conveyor frame 20 has a U-shaped cross-section and is provided with a conveying groove 21 with openings at the top and both ends. The multiple sets of drive rollers 30 are sequentially and spaced apart in the conveying groove 21 of the conveyor frame 20. The wire stripping cutter 40 is mounted on the base 10 and located above the conveyor frame 20.

[0022] The wire stripping tool 40 includes a tool holder 41, a tool support 42, and multiple blades 43. The tool holder 41 includes two sets of base plates 411 and two sets of connecting frames 412. The two sets of base plates 411 are horizontally spaced apart, and the two sets of connecting frames 412 are both n-shaped, spanning between the two sets of base plates 411, with both ends fixedly connected to the top of the two sets of base plates 411. The tool support 42 has an n-shaped cross-section and is provided with a tool groove 421 with openings at the bottom and both ends. The tool support 42 is mounted on the tool holder 41 and located inside the connecting frames 412. Multiple blades 43 are sequentially spaced within the tool grooves 421 of the tool support 42, with the lowest points of the multiple blades 43 arranged in a sequentially ascending order.

[0023] During wire stripping, one end of the wire is fed into the conveying groove 21 and the cutting groove 421. Driven by the transmission roller 30, the wire is automatically conveyed to the other side. During the conveying process, multiple blades 43 located above the wire rotate synchronously and cut, gradually splitting the outer layer of the wire insulation. Since the blades 43 are arranged in order of depth, the shallower blades will perform the initial cutting first, and then the deeper blades will further cut along the cut marks. In this way, the cutting pressure borne by each blade during the cutting process is greatly reduced, ultimately extending the service life of the blades 43.

[0024] The tool holder 41 also includes a pivot bracket 413 and an adjusting bracket 414. A limiting adjusting rod 422 is also provided on the outer side of the tool holder 42. Both the pivot bracket 413 and the adjusting bracket 414 are fixedly mounted on the tool holder 41 and located on the outer side of the tool holder 42. The pivot bracket 413 has a pivot hole 413a, and the adjusting bracket 414 has an adjusting hole 414a. The pivot of the blade 43 at one end of the tool holder 42 extends through and passes through the pivot hole 413a on the pivot bracket 413, allowing for rotational adjustment. The limiting adjusting rod 422 is located on the outer side of the other end of the tool holder 42, and it also slides through the adjusting hole 414a of the adjusting bracket 414.

[0025] When stripping wires with varying insulation thicknesses, simply adjust the tilt of the blade holder 42 according to the insulation thickness. The multiple blades 43 within the blade holder 42 will simultaneously change their cutting depth differences. When the cutting depth difference between the first and last blades 43 matches the insulation thickness, this ensures that each blade 43 still follows a progressive cutting method, starting with a shallower blade for initial cutting and then using a deeper blade to further cut along the existing cut marks. This also guarantees that the insulation is completely stripped.

[0026] Specifically, in this embodiment, multiple blades 43 on the tool holder 42 are synchronously powered, and the diameters of these blades 43 are arranged in descending order. The synchronously powered connection of multiple blades 43 of different sizes results in less force during initial cutting and greater force during deep cutting, further optimizing the progressive cutting and stripping effect. The upper end of the tool holder 42 is also equipped with an adjustment handle 423. With the adjustment handle 423, fingers can be kept relatively away from the blades 43 during adjustment, improving safety.

[0027] The wire stripping machine 100 also includes a lifting adjustment rod 50 and an auxiliary slide rod 60, with a corresponding sliding hole 411a on the base plate 411. Both the lifting adjustment rod 50 and the auxiliary slide rod 60 are fixedly mounted on the base 10. The upper end of the lifting adjustment rod 50 is fixedly connected to the bottom of the base plate 411 and can drive the wire stripping cutter 40 to move up and down. The auxiliary slide rod 60 passes through the sliding hole 411a on the base plate 411 to balance and limit the wire stripping cutter 40. The lifting adjustment rod 50 can adjust the distance between the blade 43 and the transmission roller 30, thereby enabling the wire stripping machine 100 to transport wires of different diameters for stripping.

[0028] The wire stripper 100 also includes a conveyor motor 70 and a stripping motor 80. The conveyor motor 70 is mounted on the base 10 and is poweredly connected to multiple drive rollers 30. The stripping motor 80 is mounted on the base plate 411 and is poweredly connected to multiple blades 43. Multiple motors drive the drive rollers 30 and blades 43 respectively, providing greater conveying and cutting power to the wire stripper 100, making the wire stripping process more efficient and smooth.

[0029] In summary, the beneficial effects of this utility model's long-service-life wire stripping tool 40 and wire stripping machine 100 equipped with the tool are as follows: by designing multiple blades 43 on the tool, with the cutting edges of the multiple blades 43 arranged in order of depth, the wire insulation can be cut sequentially from shallow to deep during the wire stripping process. This reduces the cutting pressure borne by a single blade 43, thereby extending the service life of the wire stripping tool 40. The adjustable structure of the wire stripping tool 40 and the wire stripping machine allows it to strip wires and cables of different diameters and insulation thicknesses, greatly expanding the applicability of the wire stripping machine 100. This utility model is highly practical and has significant potential for widespread application.

[0030] The embodiments described above illustrate only one implementation of the utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept, and these all fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be determined by the appended claims.
