Description

Technical Field

[0001] The present invention belongs to the technical field of cable production, and more specifically, relates to a device for detecting bulging defects of cable insulation sheaths. The present invention also relates to a method for detecting bulging defects of cable insulation sheaths. Background Art

[0002] During the insulation extrusion production of cables (wires), bulging defects may appear on the insulation sheath of the wires due to reasons such as the quality of the copper strands, the quality of the plastic raw materials, the extrusion temperature setting, and improper cooling process. The appearance of bulges not only causes poor appearance quality of the wires, affecting subsequent use, but also has a significant impact on the service life of the wires. The production line speed of wire insulation extrusion is relatively fast, and the wire cross-section is small, making it difficult to detect with the naked eye. Finished wires with bulging defects are packaged and then flow to customers. If the bulge is more obvious, it is very easy to be judged as unqualified, and doubts will be cast on the quality of the batch of products, resulting in batch returns and exchanges. Rework and repairs are bound to cause large economic losses.

[0003] For the online detection of bulge defects, the most advanced method is to configure a laser bump detection instrument. The method of using a laser bump detection instrument is relatively expensive, and it is necessary to ensure that the wire jitter is small. The method of using an over-shaping mold is simple and practical, but if the wire is broken, it is time-consuming to re-thread and rewind the wire to resume production, so it cannot effectively meet the requirements.

[0004] In the prior art, there is a technology named "a new energy battery bulge monitoring alarm device" and the publication (announcement) number is "CN116487814A". This technology belongs to the field of battery detection, specifically a new energy battery bulge monitoring alarm device, including a detection alarm box, the internal thread of the detection alarm box is connected with a threaded rod, and one end of the threaded rod is integrated with a rotating handle, and the other end of the threaded rod is provided with a sliding plate, the bottom of the sliding plate is integrated with a slider, and the bottom of the slider is provided with a slide groove, the internal sliding connection of the sliding plate is connected with a push rod, one end of the push rod is slidably connected with an alarm sensor, and the other end of the alarm sensor is fixedly connected with a bracket, the outer wall of the alarm sensor is electrically connected with a wire, and one end of the wire is electrically connected with an alarm; by providing an adjustment outer cylinder and an adjustment inner cylinder, it is convenient to fix batteries of different shapes, and it can be ensured that the battery bulge phenomenon is discovered and processed in time, and by providing a heat dissipation seam, it is convenient to dissipate the heat generated by the battery inside the device in time, thereby increasing the service life of the battery. However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in view of the shortcomings of the existing technology, a cable insulation sheath bulge defect detection device with a simple structure is provided, which can adapt to the cable production rhythm, can conveniently and reliably realize the cable insulation sheath bulge defect detection, eliminate minor bulges, block serious bulges, improve the cable detection performance, avoid the flow of unqualified products into the market due to the existence of serious bulges, and at the same time eliminate bulges to increase the service life of the cable.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0007] The present invention relates to a device for detecting bulging defects of cable insulation sheaths. A mold base is movably mounted in a base channel in the middle of a base. A limiting convex portion is arranged at one end of an inner wall of the base channel of the base. A small-diameter section and a large-diameter section are arranged on an outer ring of the mold base. A groove is arranged on an outer ring of the large-diameter section. A magnetic ring is arranged in the groove. A compression spring is arranged on the small-diameter section. An installation channel is also arranged on the base. The installation channel extends from a cable input side to a cable output side. A magnetically controlled switch is installed in the installation channel. A mold base channel is arranged on an inner ring of the mold base. A shaping mold is arranged in the mold base channel. The shaping mold comprises a shaping mold upper component and a shaping mold lower component.

[0008] The mold base and the base are both cylindrical structures, and the diameter of the base channel of the base is larger than the diameter of the large diameter section of the mold base.

[0009] The grooves of the outer ring of the large diameter section are arranged around the outer ring of the large diameter section, and the magnetic ring is a circular ring structure, and the magnetic ring is clamped between the grooves and the base channel.

[0010] The compression spring is located in the annular cavity between the small diameter section of the outer ring of the die base and the base channel of the base, one end of the compression spring abuts against the limiting convex part, and the other end of the compression spring abuts against the step part of the junction of the large diameter section and the small diameter section.

[0011] The large diameter section of the base is close to the cable input side, and the small diameter section of the base is close to the cable output side.

[0012] A shaping mold mounting ring groove is arranged in the mold base, the diameter of which is larger than the diameter of the mold base channel, a limiting step is arranged between the shaping mold mounting ring groove and the mold base channel, and the shaping mold mounting ring groove is close to the cable input side.

[0013] The cable is arranged to be shaped by a shaping die in a die base channel of a die base from the cable input side and then leave the die base channel.

[0014] The side of the base 4 is provided with a threaded hole, and the bolt is provided with a structure that can pass through the mounting plate and be screwed and connected in the threaded hole.

[0015] The length dimension of the mold base is greater than that of the base, and a limiting ring groove is arranged near the outer end of the small diameter section of the mold base, and a structure capable of clamping a limiting ring is arranged in the limiting ring groove.

[0016] The present invention also relates to a cable insulation outer skin bulge defect detection method with simple steps, adapted to the cable production rhythm, capable of conveniently and reliably realizing cable insulation outer skin bulge defect detection, eliminating slight bulges, blocking severe bulges, improving cable detection performance, avoiding unqualified products from entering the market due to severe bulges, and eliminating bulges to increase the service life of the cable. The detection steps of the cable insulation outer skin bulge defect detection method are as follows:

[0017] S1: Select a shaping mold corresponding to the cable specification to be tested, and install it into the shaping mold installation ring groove 21 of the mold base 2;

[0018] S2: The cable is transported from the cable input side to the cable output side through the shaping die and the die base channel; when the cable has bulges, it is blocked when passing through the shaping die, and the slight bulge disappears after being squeezed by the shaping die;

[0019] S3: If the bulge cannot be squeezed out by the shaping die, it cannot pass through the shaping die. The cable continues to move forward under the traction of the winding device. The cable exerts force on the shaping die, driving the shaping die to move. The shaping die overcomes the effect of the compression spring and pushes the die base to move toward the cable output side. The movement of the die base drives the magnetic ring to move synchronously. When the magnetic ring approaches the magnetic control switch, the magnetic control switch senses the magnetic ring and controls the winding device to stop through the control line.

[0020] S4: The operator processes the bulge of the cable with bulge defect that stays at the shaping mold; then resumes production, the force applied by the shaping mold disappears, the cable is re-transported, and the shaping mold is reset under the action of the compression spring;

[0021] S5: Repeat the above steps to continuously complete the detection and processing of the insulation sheath bulge of the cable 1.

[0022] The technical solution of the present invention is adopted, and the working principle and beneficial effects are as follows:

[0023] The cable insulation outer skin bulge defect detection device of the present invention is structured to separately make a shaping die, a die base, a compression spring, a base, a magnetic ring and a magnetic control switch; the magnetic ring is fixed in the groove of the outer ring of the large diameter section of the die base to achieve reliable connection of the magnetic ring; the compression spring is set in the outer ring of the small diameter section of the die base; the die base with the compression spring and the magnetic ring is inserted into the base channel of the base, one end of the small diameter section of the die base extends to the outside of one side of the base, and a limiting ring groove is set at the position where the small diameter section of the die base extends to the outside of the die base, and the relative position of the die base and the base is limited by the limiting ring (circlip) clamped in the limiting ring groove to prevent the die base from falling off the base and keep the two as one; an axially arranged installation channel (or through groove) is set on the outer circle of the base for installing the magnetic control switch. The base can be fixedly connected to the corresponding component. In this way, cables with bulging defects cannot pass through the shaping die. The cable continues to move forward under the traction of the winding device, driving the shaping die to move. The shaping die overcomes the pressure of the compression spring and pushes the die base to move. The movement of the die base makes the magnetic ring close to the magnetic control switch. When the magnetic control switch senses the magnetic ring, the winding device is stopped through the control line to avoid the cable being broken. On the one hand, this structure can handle the bulging of cables with slight bulging, and the operation is simple. For cables with serious bulging, the cable is controlled to stop moving, which is convenient for operators to eliminate the bulging on site. BRIEF DESCRIPTION OF THE DRAWINGS

The above structure proposes an improved technical solution to the deficiencies in the prior art. When setting up the structure, the shaping mold 6, the mold base 2, the compression spring 3, the base 4, the magnetic ring 5 and the magnetic control switch 7 are respectively made; the magnetic ring 5 is set and fixed in the groove 12 of the outer ring of the large diameter section 11 of the mold base 2 to achieve reliable connection of the magnetic ring 5; the compression spring 3 is set in the outer ring of the small diameter section 10 of the mold base 2; the mold base 2 with the compression spring 3 and the magnetic ring 5 is inserted into the base channel 8 of the base 4, one end of the small diameter section of the mold base 2 extends to the outside of one side of the base 4, and the position where the small diameter section 10 of the mold base 2 extends to the outside of the mold base 2 is set with a limiting ring groove 26, and the relative position of the mold base 2 and the base 4 is limited by the limiting ring (circlip) clamped in the limiting ring groove, so as to prevent the mold base 2 from falling off the base 4 and keep the two as one; an axially arranged installation channel 13 (or through groove) is set on the outer circle of the base 4 for installing the magnetic control switch 7. The base 4 can be fixedly connected to the corresponding component. The workflow for testing is: select a shaping mold 6 corresponding to the specification of the cable 1 to be tested, and install it in the shaping mold installation ring groove 21 of the mold base 2; the cable 1 is transported from the cable input side 19 to the cable output side 20 through the shaping mold 6 and the mold base channel 14; when the cable 1 has a bulge, it is blocked when passing through the shaping mold 6, and a slight bulge disappears after being squeezed by the shaping mold 6; a serious bulge that cannot be squeezed out by the shaping mold 6 cannot pass through the shaping mold 6, and the cable 1 continues to move forward under the traction of the winding device, and the cable applies force to the shaping mold 6 to drive the shaping mold 6 moves, the shaping die 6 overcomes the effect of the compression spring 3 and pushes the die base 2 to move toward the cable output side 20, and the movement of the die base 2 drives the magnetic ring 5 to move synchronously; when the magnetic ring 5 is close to the magnetic control switch 7, the magnetic control switch 7 senses the magnetic ring 5, and controls the winding equipment to stop through the control line; the operator processes the bulge of the cable 1 with bulging defects that stays at the shaping die 6; then the production is resumed, the force applied by the shaping die 6 disappears, the cable 1 is re-conveyed, and the shaping die 6 is reset under the action of the compression spring 3; the above steps are repeated to continuously complete the detection and processing of the insulation sheath bulge of the cable 1.In this way, the cable 1 with bulging defects cannot pass through the shaping mold 6. The cable 1 continues to move forward under the traction of the winding device, driving the shaping mold 6 to move. The shaping mold overcomes the pressure of the compression spring 3 and pushes the die base 2 to move. The movement of the die base 2 makes the magnetic ring 5 close to the magnetic control switch 7. When the magnetic control switch 7 senses the magnetic ring 5, the winding device is stopped through the control line to prevent the cable 1 from being broken. On the one hand, this structure can handle the bulging of cables with slight bulging, and the operation is simple. For cables 1 with severe bulging, the cable 1 is controlled to stop moving, which is convenient for operators to eliminate the bulging on site. The cable insulation outer skin bulging defect detection device described in the present invention has a simple structure, adapts to the cable production rhythm, can conveniently and reliably realize the cable insulation outer skin bulging defect detection, eliminates slight bulging, blocks severe bulging, improves the cable detection performance, and avoids the flow of unqualified products into the market due to the existence of severe bulging. At the same time, the bulging is eliminated to increase the service life of the cable.

[0030] The mold base 2 and the base 4 are both cylindrical structures, and the diameter of the base channel 8 of the base 4 is larger than the diameter of the large diameter section 11 of the mold base 2. In the above structure, the mold base channel of the mold base is a cylindrical structure, and the base channel of the base is a cylindrical structure. The large diameter section facilitates the base and the mold base to be movably connected, and there is no shaking between the two. A compression spring is conveniently set between the small diameter section and the base channel. One end of the compression spring is limited by a limiting convex portion, and the other end of the compression spring is limited by a step portion 18. When the force applied by the cable acts on the shaping mold, the compression spring is squeezed, and the mold base moves relative to the base. After the bulge is eliminated, the mold base 2 is reset under the action of the compression spring 3.

[0031] The groove 12 of the outer ring of the large diameter section 11 of the die base 2 is arranged along the outer ring of the large diameter section 11, and the magnetic ring 5 is a circular ring structure, and the magnetic ring 5 is clamped between the groove 12 and the base channel 4. In the above structure, the magnetic ring 5 is fixedly arranged on the die base 2. When the die base 2 is not subjected to force, the distance between the magnetic ring 5 and the magnetic control switch 7 is greater than the reaction range, and the winding device will not be controlled to stop at this time.

[0032] The compression spring 3 is located in the annular cavity 17 between the small diameter section 10 of the outer ring of the die base 2 and the base channel 8 of the base 2, one end of the compression spring 3 abuts against the limiting convex portion 9, and the other end of the compression spring 3 abuts against the step portion 18 at the junction of the large diameter section 11 and the small diameter section 10. The above structure ensures reliable limiting of the compression spring, and can reliably achieve extrusion and reset of the compression spring.

[0033] The large diameter section 11 of the base 4 is close to the cable input side 19, and the small diameter section 10 of the base 4 is close to the cable output side 20. A shaping mold mounting annular groove 21 is provided in the die base 2, and the diameter of the shaping mold mounting annular groove 21 is larger than the diameter of the die base channel 14. A limiting step 22 is provided between the shaping mold mounting annular groove 21 and the die base channel 14, and the shaping mold mounting annular groove 21 is close to the cable input side 19. The cable 1 is configured to be able to be shaped from the cable input side 19 through the shaping mold 6 in the die base channel 14 of the die base 2, and then leave the die base channel 14. In the above structure, when the cable 1 passes through, it enters from one end of the cable input side 19 and then leaves from the cable output side 20. The limiting step is used to limit the shaping mold 6 to ensure that the shaping mold 6 is reliably positioned. The shaping mold 6 includes a shaping mold upper component 15 and a shaping mold lower component 16. Both the shaping mold upper component 15 and the shaping mold lower component 16 are C-shaped structures, which are convenient for being clamped in the shaping mold mounting ring groove 21 of the cylindrical structure, and the bottom rests on the limiting step 22.

[0034] The base 4 has a threaded hole 23 on its side, and the bolt 24 is configured to be able to pass through the mounting plate 25 and be screwed into the threaded hole 23. In the above structure, a threaded hole 41 is provided on one end face of the base 4, which is used to reliably realize a fixed connection with the mounting plate through the bolt 24.

[0035] The length of the die base 2 is greater than the length of the base 4. A limiting ring groove 26 is provided near the outer end of the small diameter section 10 of the die base 2. A structure capable of clamping a limiting ring 27 is provided in the limiting ring groove 26. With the above structure, after the die base 2 and the base 4 are movably connected, the end of the small diameter section of the die base 2 extends to the outside of the base channel, which is convenient for installing a limiting ring for limiting.

[0036] The present invention also relates to a cable insulation outer skin bulge defect detection method with simple steps, adapted to the cable production rhythm, capable of conveniently and reliably realizing cable insulation outer skin bulge defect detection, eliminating slight bulges, blocking severe bulges, improving cable detection performance, avoiding unqualified products from entering the market due to severe bulges, and eliminating bulges to increase the service life of the cable. The detection steps of the cable insulation outer skin bulge defect detection method are as follows:

[0037] S1: Select a shaping mold 6 corresponding to the specification of the cable 1 to be tested, and install it into the shaping mold installation ring groove 21 of the mold base 2;

[0038] S2: The cable 1 is transported from the cable input side 19 to the cable output side 20 through the shaping die 6 and the die base channel 14; when the cable 1 has a bulge, it is blocked when passing through the shaping die 6, and the slight bulge disappears after being squeezed by the shaping die 6;

[0039] S3: If the bulge cannot be squeezed out by the shaping die 6, it cannot pass through the shaping die 6. The cable 1 continues to move forward under the traction of the winding device. The cable exerts force on the shaping die 6, driving the shaping die 6 to move. The shaping die 6 overcomes the effect of the compression spring 3 and pushes the die base 2 to move toward the cable output side 20. The movement of the die base 2 drives the magnetic ring 5 to move synchronously. When the magnetic ring 5 approaches the magnetic control switch 7, the magnetic control switch 7 senses the magnetic ring 5 and controls the winding device to stop through the control circuit.

[0040] S4: The operator processes the bulge of the cable 1 with bulge defect that stays at the shaping mold 6; then resumes production, the force applied by the shaping mold 6 disappears, the cable 1 is re-transported, and the shaping mold 6 is reset under the action of the compression spring 3;

[0041] S5: Repeat the above steps to continuously complete the detection and processing of the insulation sheath bulge of the cable 1.

[0042] The cable insulation outer skin bulge defect detection device of the present invention is structured, and the shaping mold 6, the mold base 2, the compression spring 3, the base 4, the magnetic ring 5 and the magnetic control switch 7 are respectively made; the magnetic ring 5 is set and fixed in the groove 12 of the outer ring of the large diameter section 11 of the mold base 2 to achieve reliable connection of the magnetic ring 5; the compression spring 3 is set in the outer ring of the small diameter section 10 of the mold base 2; the mold base 2 with the compression spring 3 and the magnetic ring 5 is inserted into the base channel 8 of the base 4, one end of the small diameter section of the mold base 2 extends to the outside of one side of the base 4, and the position where the small diameter section 10 of the mold base 2 extends to the outside of the mold base 2 is provided with a limiting ring groove 26, and the relative position of the mold base 2 and the base 4 is limited by the limiting ring clamped in the limiting ring groove, so as to prevent the mold base 2 from falling off the base 4 and keep the two as one; the outer circle of the base 4 is provided with an axially arranged installation channel 13 for installing the magnetic control switch 7. The base 4 can be fixedly connected to the corresponding component. In this way, the cable 1 with bulging defects cannot pass through the shaping die 6. The cable 1 continues to move forward under the traction of the winding device, driving the shaping die 6 to move. The shaping die overcomes the pressure of the compression spring 3 and pushes the die base 2 to move. The movement of the die base 2 makes the magnetic ring 5 close to the magnetic control switch 7. When the magnetic control switch 7 senses the magnetic ring 5, the winding device is stopped through the control line to prevent the cable 1 from being broken. On the one hand, this structure can handle the bulging of cables with slight bulging, and the operation is simple. On the other hand, for cables with serious bulging, the cable 1 is controlled to stop moving, which is convenient for operators to handle on site.
