Description

Technical Field

[0001] This application relates to the technical field of wire stripping, and particularly to an automatic wire stripping device. Background Art

[0002] Wires are the most common materials in current power equipment, with their outer diameters ranging from 10 mm to 50 mm; the tensile strength of the materials used ranges from 200 MPa to 1900 MPa. Due to the large differences in structure and materials, defective wires need to be stripped and then re-produced. The traditional wire stripping method uses manual wire stripping, which not only has low efficiency but also unsatisfactory wire stripping effect.

[0003] Therefore, how to provide an effective wire stripping device to reduce the cost of manual wire stripping and save wire stripping time is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] This application provides an automatic wire stripping device to solve the problems of low efficiency and unsatisfactory wire stripping effect in the traditional wire stripping method in the prior art.

[0005] This application provides an automatic wire stripping device, including: A rotating seat, which is provided with a central wire passing hole penetrating axially, and the central wire passing hole is used for the first wire body to pass through; A wire stripping disc, which is arranged on the rotating seat and extends radially along the rotating seat. A side wire passing channel is formed on the wire stripping disc, and the side wire passing channel is used for the second wire body to pass through. The wire stripping disc can rotate driven by the rotating seat to separate the twisted first wire body and the second wire body from each other.

[0006] In a possible design, the side wire passing channel is arranged on the side of the wire stripping disc away from the central wire passing hole.

[0007] In a possible design, an opening groove is formed on the side of the wire stripping disc away from the central wire passing hole, and guide rollers are arranged at intervals in the opening groove. The roller surface of the guide roller away from the central wire passing hole is used to contact the second wire body.

[0008] In a possible design, pressure rollers are also arranged at intervals in the opening groove. The roller surface of the pressure roller close to the central wire passing hole is used to contact the second wire body, and a side wire passing channel is formed between the pressure roller and the guide roller.

[0009] In a possible design, there are multiple wire stripping discs, and the multiple wire stripping discs are respectively arranged at intervals along the circumferential direction on the side wall of the rotating seat.

[0010] In a possible design, an end flange is arranged at the end of the rotating seat, and the end flange is used to connect with a rotating device. Side wire passing holes corresponding to the respective side wire passing channels are formed on the end flange.

[0011] In a possible design, it further includes a straightening member. The straightening member is arranged on the downstream side of the wire stripping disc. The straightening member includes a housing and a plurality of straightening belts arranged on the inner wall of the housing. The housing has an inlet and an outlet arranged opposite to each other. The free ends of the straightening belts extend towards the central axis of the housing.

[0012] In a possible design, the straightening member further includes a bushing. The bushing is sleeved on the inner wall of the housing, and the straightening belts are formed on the inner wall of the bushing.

[0013] In a possible design, it further includes a heating member. The heating member is arranged between the wire stripping disc and the straightening member and is used to heat up the second wire body before it enters the housing.

[0014] In a possible design, it further includes a winding assembly. The winding assembly includes: A fixing frame; A rotating frame rotatably mounted on the fixing frame; A winding roller arranged on the rotating frame. The winding roller can rotate synchronously with the rotating frame while rotating around its own axis.

[0015] The beneficial effects of the present application are as follows: The automatic wire stripping device of the present application is used to quickly separate the first wire body and the second wire body that are twisted with each other. Among them, by passing the first wire body through the central wire passing hole on the rotating seat and passing the second wire body through the side wire passing channel on the wire stripping disc, when the rotating seat drives the wire stripping disc to rotate synchronously, it can drive the second wire body to rotate around the first wire body, so that the second wire body is disengaged from the first wire body, and the first wire body and the second wire body that are twisted together are quickly separated.

[0016] By setting the heating member, the second wire body can be moderately heated to soften it. When the moderately softened second wire body passes through the straightening member, the friction force between the straightening belt and the surface of the second wire body is used to straighten the bent section of the second wire body, and at the same time, the second wire body is prevented from being damaged. In this way, the bent section formed due to twisting can be straightened again, and the second wire body after wire stripping is kept straight, providing qualified wire materials for reproduction production.

[0017] By setting the winding assembly, on the one hand, the rotation of the winding roller around its own axis can wind up the second wire body again. On the other hand, the revolution of the rotating frame driving the winding roller can automatically untangle the second wire body itself before winding, providing qualified wire materials for reproduction production.

Specific embodiments

[0021] The following will clearly and completely describe the technical solutions of the present application in combination with the embodiments. Obviously, the described embodiments are some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0022] The wire is usually made by twisting multiple wire bodies together. Generally, at least one second wire body 920 is wound around a first wire body 910 to form a twisted structure. However, during the production process, there will be some defective wire products during the inspection of wire products. For these defective wires, the second wire body 920 needs to be stripped from the first wire body 910 for subsequent reuse in production. Currently, the manual wire stripping method is not only inefficient but also the wire stripping effect is not ideal.

[0023] The following will describe the automatic wire stripping device provided in the embodiments of the present application in conjunction with Figures 1-6 ,

[0024] Referring to Figure 1 , Figure 2 As shown in the figures, the automatic wire stripping device provided in the embodiments of the present application includes a rotating seat 100 and a wire stripping disc 200. The rotating seat 100 is used for driving connection with a motor to realize rotation around its own axis. A central wire passing hole 110 penetrating along the axial direction of the rotating seat 100 is provided on the rotating seat 100, and the central wire passing hole 110 is used for the first wire body 910 to pass through. The wire stripping disc 200 is welded or bolted or integrally formed on the outer wall of the rotating seat 100. The disc surface of the wire stripping disc 200 extends radially outward along the rotating seat 100, and the length direction of the wire stripping disc 200 extends along the axial direction of the rotating seat 100. A side wire passing channel 210 is formed on the wire stripping disc 200. The side wire passing channel 210 is arranged on the side of the wire stripping disc 200 away from the central wire passing hole 110, and the side wire passing channel 210 is used for the second wire body 920 to pass through. Specifically, the side wire passing channel 210 is curved, and the distance between the two ends of the side wire passing channel 210 and the rotating seat 100 is less than the distance between the middle part of the side wire passing channel and the rotating seat 100. In this way, it is beneficial for the second wire body 920 to complete a smooth transition between the first wire body 910 and the side wire passing channel, making the friction force at each contact point more uniform and avoiding damage to the second wire body 920 caused by a large friction force at the inflection point.

[0025] When the rotating seat 100 rotates around its own axis, the wire stripping disc 200 can rotate driven by the rotating seat 100, thereby driving the second wire body 920 to rotate, while the first wire body 910 does not rotate. In this way, the originally twisted first wire body 910 and the second wire body 920 will be quickly separated and stripped.

[0026] Referring to Figure 1 , Figure 2As shown, in some specific embodiments, an opening groove 220 is formed on one side of the wire stripping disc 200 away from the central wire passing hole 110. Guide rollers 300 are arranged at intervals in the opening groove 220. The roller surface of the guide roller 300 away from the central wire passing hole 110 is used to contact the second wire body 920. By providing the opening groove 220, it is more convenient for the end of the second wire body 920 to pass through the measuring wire passing channel. By providing the guide rollers 300, the guide rollers 300 can rotate around their own axes, thereby converting the sliding friction between the second wire body 920 and the wire stripping disc 200 into the rolling friction between the second wire body 920 and the guide rollers 300, thereby reducing the frictional resistance when the second wire body 920 advances and avoiding damage to the second wire body 920 caused by excessive frictional force.

[0027] Referring to Figure 1 , Figure 2 As shown, in some specific embodiments, pressure rollers 400 are also arranged at intervals in the opening groove 220. The pressure rollers 400 are located at positions close to the notch of the opening groove 220, and the guide rollers 300 are located at positions close to the bottom of the opening groove 220. The pressure rollers 400 and the guide rollers 300 are arranged at intervals in sequence, and a side wire passing channel 210 is formed between the pressure rollers 400 and the guide rollers 300. When the second wire body 920 passes through the measuring wire passing channel successively through each guide roller 300 and pressure roller 400, the roller surface (inner roller surface) of the pressure roller 400 close to the central wire passing hole 110 contacts the second wire body 920, and the roller surface (outer roller surface) of the guide roller 300 away from the central wire passing hole 110 contacts the second wire body 920. Thus, when the rotating seat 100 drives the wire stripping disc 200 to rotate, the pressure rollers 400 can prevent the second wire body 920 from slipping out of the notch of the opening groove 220 due to centrifugal force.

[0028] In some specific embodiments, there are multiple wire stripping discs 200, such as two, three, or more. The multiple wire stripping discs 200 are respectively arranged at intervals along the circumferential direction on the side wall of the rotating seat 100. Each wire stripping disc 200 corresponds to a second wire body 920 respectively, and is suitable for wire stripping of wires in which multiple second wire bodies 920 are twisted on the first wire body 910. When the rotating seat 100 drives each wire stripping disc 200 to rotate, all the second wire bodies 920 can be driven to rotate synchronously so as to be peeled off from the first wire body 910.

[0029] Referring to Figure 1As shown, in some specific embodiments, an end flange 500 is fixed to the end of the rotating seat 100, and the end flange 500 is used to connect with the rotating device. For example, the end flange 500 is fixed to the inner side of the pulley by bolts, and the pulley is connected to the motor through a belt. The action of the motor can drive the pulley and the end flange 500 to rotate, thereby driving the rotating seat 100 to rotate. Side wire holes 510 corresponding to each side wire channel 210 are opened on the end flange 500. Specifically, the side wire holes 510 are evenly distributed along the circumference of the end flange 500. The side wire holes 510 correspond to a second wire body 920 respectively, which is suitable for stripping wires of multiple second wire bodies 920 twisted on the first wire body 910. After stripping, the second wire bodies 920 pass through the corresponding side wire holes 510 and reach the subsequent workstations.

[0030] Reference Figure 3 , Figure 4 As shown, in some specific embodiments, a straightening member 600 is further provided on the downstream side of the stripping disc 200, and the straightening member 600 includes a housing 610 and a plurality of straightening belts 620 provided on the inner wall of the housing 610, the housing 610 has an inlet 611 and an outlet 612 provided opposite to each other, and the free end of the straightening belt 620 extends toward the outlet 612 toward the central axis of the housing 610. The second wire body 920 enters the housing 610 from the inlet 611 and passes through the outlet 612 along the central axis of the housing 610, so that the free end of the straightening belt 620 gathers around the second wire body 920. When the second wire body 920 passes through the wire outlet 612, the straightening belt 620 is dragged backwards, and the free end is in a posture of extending along the second wire body 920 toward the wire outlet 612. In this way, the free ends of all the straightening belts 620 will gather at a position close to the wire outlet 612, so that the friction between the second wire body 920 near the wire outlet 612 and the straightening belt 620 gradually increases, and the bent section of the second wire body 920 is straightened under the action of the friction force, and at the same time, the second wire body 920 can be prevented from being damaged. In this way, the bent section formed by twisting can be straightened again, so that the second wire body 920 after stripping remains straight, providing qualified wire for reproducing production.

[0031] In some specific embodiments, the straightening belt 620 is made of a rubber belt with greater friction, so that the straightening belt 620 can provide greater friction by gathering in a limited space while maintaining flexibility. In some specific embodiments, a bushing 630 is further provided in the housing 610, and the bushing 630 is sleeved on the inner wall of the housing 610. The material of the bushing 630 is the same as that of the straightening belt 620, and the straightening belt 620 is directly formed on the inner wall of the bushing 630, so that the straightening belt 620 is easily installed in the housing 610.

[0032] Reference Figure 4As shown, in some specific embodiments, the housing 610 is a tapered sleeve with a larger opening at one end and a smaller opening at the other end, and the bushing 630 is a tapered bushing 630 that matches the inner wall of the housing 610. Specifically, the diameter of the inlet 611 is larger, and the diameter of the outlet 612 is smaller. In this way, the larger inlet 611 facilitates the insertion of the bushing 630 into the housing 610, and the smaller outlet 612 prevents the bushing 630 from being dragged out of the housing 610 by the second wire body 920. At the same time, since the diameter of the inlet 611 is larger and the diameter of the outlet 612 is smaller, it is beneficial for the belt 620 to gather more tightly at the position near the outlet 612 than at the position of the inlet 611. In the direction from the inlet 611 to the outlet 612, a gradually increasing frictional force can be provided for the second wire body 920, and at the position near the outlet 612, the frictional force reaches the maximum, so that the bent second wire body 920 can be restored to a straight state.

[0033] Referring to Figure 4 、 Figure 5 As shown, in some specific embodiments, a heating member 700 is further provided between the wire stripping disc 200 and the straightening member 600. The heating member 700 is used to heat the second wire body 920 before it enters the housing 610, so as to moderately soften the second wire body 920, which is beneficial for subsequent straightening by the straightening member 600. Specifically, the heating member 700 includes a first hot roller 710 and a second hot roller 720. The roller surfaces of the first hot roller 710 and the second hot roller 720 are both arc-shaped surfaces, and the roller surfaces of the first hot roller 710 and the second hot roller 720 are concave inward at the central position. In this way, the second wire body 920 can pass through the concave portion of the roller surface. When the second wire body 920 passes between the first hot roller 710 and the second hot roller 720, the first hot roller 710 and the second hot roller 720 rotate around their own axes respectively and provide heat for the second wire body 920. For example, heating cavities are provided at positions near the roller surfaces of the first hot roller 710 and the second hot roller 720, and heat-conducting oil is filled in the heating cavities. The temperature of the heat-conducting oil is 40 - 50 °C, which can heat the second wire body 920 passing between the first hot roller 710 and the second hot roller 720 and improve its softness. Another example is that electric heating wires are wound around the positions near the roller surfaces of the first hot roller 710 and the second hot roller 720, and the temperature of the electric heating wires is set to 40 - 50 °C. When the second wire body 920 passes between the first hot roller 710 and the second hot roller 720, the second wire body 920 is heated and softened. After being moderately softened, the second wire body 920 can be more easily straightened when passing through the straightening member 600, and at the same time, it can also avoid damage to the second wire body 920 due to being too hard during the straightening process.

[0034] Referring to Figure 3 、 Figure 6As shown, in some specific embodiments, a winding assembly 800 is further provided on the downstream side of the straightening member 600. The winding assembly 800 includes a fixed frame 810, a rotating frame 820, and a winding roller 830. Among them, the fixed frame 810 is fixed to the ground, the rotating frame 820 is rotatably mounted on the fixed frame 810, and the winding roller 830 is rotatably mounted on the rotating frame 820. Specifically, the rear side of the rotating frame 820 is rotatably mounted on the fixed frame 810 through a rotating shaft 840 and a bearing. A fixed shaft 850 and a gear are installed on the front side of the rotating frame 820. The axis of the fixed shaft 850 coincides with the axis of the rotating shaft 840, and the gear is in transmission connection with the motor. After the motor is started, it can drive the rotating frame 820 and the winding roller 830 thereon to rotate together around the rotating shaft 840. When the wire stripping disc 200 drives the second wire body 920 to rotate and peel off from the first wire body 910, since the end of the second wire body 920 is wound on the winding roller 830, the rear section of the second wire body 920 will be wound around itself. By providing the fixed frame 810 and the rotating frame 820, when the rotating frame 820 drives the winding roller 830 thereon to rotate, the second wire body 920 on the winding roller 830 will unwind its own winding, ensuring that the second wire body 920 automatically unwinds its own winding before winding, and providing qualified wire for reproduction production.

[0035] A winding motor 860 is further installed on the rotating frame 820. A transmission wheel 870 is sleeved on the end of the roller shaft of the winding roller 830. The winding motor 860 is connected to the transmission wheel 870 through a pulley and a belt, so that the winding motor 860 can drive the winding roller 830 to rotate self - rotatably, so that the winding roller 830 can rotate self - rotatably while rotating synchronously with the rotating frame 820, and the straightened second wire body 920 is wound around the winding roller 830.

[0036] Refer to Figure 6 As shown, in some specific embodiments, an annular guide seat 880 is installed on the fixed frame 810. The annular guide seat 880 has an annular guide rail. A guide wheel is provided on the rear side of the rotating frame 820. When the rotating frame 820 rotates around the rotating shaft 840, the guide wheel moves along the annular guide rail in the annular guide rail, thereby improving the stability of the rotating process of the rotating frame 820.

[0037] The working process of the automatic wire stripping device of the present application: The unwinding roller (not shown in the figure) rotates to unwind the wire to be stripped (twisted by the first wire body 910 and the second wire body 920) wound around the unwinding roller; at the same time, the rotating seat 100 rotates around its own axis, and the stripping disc 200 rotates driven by the rotating seat 100, thereby driving the second wire body 920 to rotate, while the first wire body 910 does not rotate, so that the originally twisted first wire body 910 and the second wire body 920 are separated and stripped. The stripped second wire body 920 passes between the first hot roller 710 and the second hot roller 720, and the second wire body 920 is heated and softened. After being moderately softened, the second wire body 920 passes through the straightening member 600 and is straightened by the straightening member 600. Finally, the straightened second wire body 920 is wound around the winding roller 830 again. The first wire body 910 after wire stripping is rewound on the take-up roller (not shown in the figure), and the take-up speed of the take-up roller is synchronized with the unwinding speed of the unwinding roller.
