Description

Technical Field

[0001] The present invention relates to the technical field of wire straightening, in particular to a wire straightening mechanism and a profiling device for electromagnetic wire raw materials. Background Art

[0002] Electromagnetic wire is an insulated wire used to make coils or windings in electrical products, also known as winding wire. Electromagnetic wire must meet a variety of usage and manufacturing process requirements. The former includes its shape, specifications, ability to work at high temperatures for short and long periods of time, and withstand strong vibrations and centrifugal forces at high speeds in certain occasions, corona and breakdown resistance under high voltages, and chemical corrosion resistance in special atmospheres. The latter includes the requirements for withstanding stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during impregnation and drying. Different working environments may have different requirements for the shape of electromagnetic wire, so the electromagnetic wire needs to be press-formed. During the press-forming process, the wire needs to be fed in a straight line, otherwise the wire will deviate during the press-forming process, affecting the press-forming quality, thereby causing press-forming failure and reducing the press-forming efficiency of the wire. In the document with publication number CN210208428U, the wire is straightened by an extrusion plate, and protective cotton is provided inside the extrusion plate.

[0003] However, the existing electromagnetic wire raw material straightening mechanism and pressing device will cause serious wear of the protective cotton due to the sliding friction between the wire and the protective cotton during long-term wire pulling operation, and the wear of the protective cotton cannot be monitored. At the same time, after use, the protective cotton is easily contaminated by impurities such as dust and water stains, which will increase the degree of its wear. Moreover, after wear occurs, under the action of the spring, the two extrusion plates will deviate from the center position, causing the wire to bend, affecting the straightening effect, and thus affecting the quality of subsequent pressing.

[0019] See also Figures 1-9 The present invention provides a straightening mechanism for electromagnetic wire raw material, comprising a protective cover 1 and further comprising: The moving mechanism is arranged in the protective cover 1 , and a cover plate 12 is connected to the moving mechanism. The cover plate 12 is used to seal and protect the protective cover 1 .

[0020] A plurality of telescopic mechanisms are provided on the inner wall of the protective cover 1 , and each telescopic mechanism is connected to a U-shaped plate 1101 , and the telescopic mechanism is used to telescope the U-shaped plate 1101 .

[0021] The straightening roller 1103 rotates on the side wall of the U-shaped plate 1101 through the first rotating shaft 1102, and the side wall fixed sleeve of the straightening roller 1103 is provided with a protective cotton 1104. In this embodiment, the curved surface shape of the roller body of the straightening roller 1103 is a hyperbola, showing the characteristics of large diameters at both ends and small diameters in the middle. Viewed from the side, the contour line of the roller body is part of the hyperbola. Viewed from the axial section, the contact line between the roller body and the material to be straightened is a curve, which can perform straightening operations on the round wire body 10.

[0022] In another implementation of this embodiment, a straightening roller 1103 with a flat groove-shaped main roller surface can also be used. A rectangular groove matching the width of the flat wire can be processed on the surface of the roller body. The bottom of the groove is flat, and the two side walls are perpendicular to the bottom of the groove, forming a "U-shaped" or "rectangular" cross-section (adjusted depending on whether the corners of the flat wire are rounded), which can perform straightening operations on the flat wire body 10.

[0023] The connecting mechanism is arranged between two adjacent U-shaped plates 1101 and is used to drive the other straightening roller 1103 to move synchronously when one of the straightening rollers 1103 is worn and bulged.

[0024] The detection mechanism is arranged in the protective cover 1, and is used to detect the wear and protrusion of the straightening roller 1103. After use, the interior of the protective cover 1 can be sealed, and the protective cotton 1104 can be protected to avoid contamination by impurities such as dust and water stains. It is convenient to detect the wear or protrusion of the protective cotton 1104 and alarm through an external alarm to remind the operator to repair and replace it. When the straightening rollers 1103 of the same group are worn or protruded, the two straightening rollers 1103 can be synchronously moved closer to or away from each other, avoiding the two straightening rollers 1103 of the same group from deviating from the center position and avoiding bending of the wire body 10, thereby ensuring the straightening effect and then ensuring the quality of subsequent profiling.

During straightening, the wire body 10 can be prevented from running off, thereby ensuring the straightening effect. During the straightening process, if the protective cotton 1104 is worn or bulged, the U-shaped plate 1101 and the straightening roller 1103 can move. At the same time, the first push pin 205 can be driven to slide in the first slide groove 203 through the L-shaped block 204, thereby driving the first connecting plate 210 to rotate along the first rotating pin 202. In addition, the scale on the second connecting plate 209 indicated by the first connecting plate 210 is detected by the visual sensor 208, so that the wear or bulge of the protective cotton 1104 can be detected, thereby facilitating the detection of the wear or bulge of the protective cotton 1104, and an external alarm is used to remind the operator to repair and replace it, thereby ensuring the straightening effect and thus ensuring the quality of subsequent pressing.

[0031] The two racks 502 are fixed to the bottom of the U-shaped plate 1101 through the first connecting rod 503 and mesh with the gear 501, so that the two racks 502 can move synchronously. When the protective cotton 1104 is worn or bulged, the U-shaped plate 1101 can move. When the U-shaped plate 1101 moves, it can drive the rack 502 to move synchronously, so that the gear 501 rotates, thereby driving the other rack 502 to move, and driving the other U-shaped plate 1101 and the straightening roller 1103 to move, so that the two straightening rollers 1103 in the same group can move synchronously towards or away from each other, avoiding the two straightening rollers 1103 in the same group from deviating from the center position and avoiding bending of the wire body 10, thereby ensuring the straightening effect and then ensuring the quality of subsequent pressing.

[0037] The third push pin 608 is fixed to the side wall of the cover plate 12 through the second connecting block 603 , so that the third push pin 608 can slide in the third sliding groove 605 .

[0038] The guide mechanism is provided on the outer wall of the protective cover 1 and is used to guide the movement of the cover plate 12. When the wire body 10 is placed between the straightening rollers 1103, the U-shaped plate 1101 can be moved in the direction close to the protective cover 1. At the same time, when the U-shaped plate 1101 moves, the second push pin 607 can be driven to slide along the second slide groove 604 through the first connecting block 606, thereby pushing the third push pin 608 to slide in the third slide groove 605, and then the two cover plates 12 can be driven away from each other through the second connecting block 603. The wire body 10 can be separated from the straightening roller 1103 when the straightening is completed and the work is stopped. At this time, the two U-shaped plates 1101 can move closer to each other under the action of the second elastic member 303. At the same time, the two cover plates 12 can be pushed to move closer to each other and resist each other, so that the interior of the protective cover 1 can be sealed and the protective cotton 1104 can be protected from being contaminated by impurities such as dust and water stains, thereby ensuring its use effect and life, and thus ensuring the quality of subsequent pressing.

[0046] The iron block 405 is fixed on the top of the movable plate 407 .

[0047] The electromagnet 406 is fixed on the top of the protective cover 1 and is arranged opposite to the iron block 405. When the wire body 10 needs to be placed between the straightening rollers 1103, the electromagnet 406 is powered off. After the electromagnet 406 is powered off, the movable plate 407 can move downward and reset under the action of the first elastic member 404, and abut against the top of the inclined plate 401. At this time, the two U-shaped plates 1101 can be pushed away from each other. At the same time, the second elastic member 303 is compressed and drives the two straightening rollers 1103 to move away from each other, thereby facilitating the The wire body 10 is placed between the straightening rollers 1103, which is more convenient and quick, and can avoid damage to the protective cotton 1104, ensuring its effectiveness and life. Then, the electromagnet 406 is energized. After the electromagnet 406 is energized, it attracts the iron block 405, causing the movable plate 407 to move upward and disengage from the inclined plate 401. At this time, the U-shaped plate 1101 can move closer to each other under the action of the second elastic member 303, and drive the straightening rollers 1103 to move synchronously, so that the protective cotton 1104 is offset from the wire body 10.

[0058] The connecting pipe 904 is connected to the air supply pipe 903 and the fixed pipe 901. After the straightening is completed, when the work is stopped, the electromagnet 406 is first powered off. After the electromagnet 406 is powered off, the movable plate 407 can move downward under the action of the first elastic member 404 and resist against the inclined plate 401, thereby pushing the U-shaped plates 1101 away from each other. At this time, the cover 12 can be opened.

At the same time, under the action of wind, the straightening roller 1103 can be blown to rotate along the first rotating shaft 1102, so that the cleaning efficiency of the surface of the protective cotton 1104 is higher and the effect is better.

[0059] See also Figure 5 A wire profiling device for electromagnetic wire raw materials includes a wire profiling device body 13. The wire profiling device body 13 is a well-known technology in this technical field and is not elaborated here. It also includes an electromagnetic wire raw material wire straightening mechanism. The electromagnetic wire raw material wire straightening mechanism is arranged at the inlet of the wire profiling device body 13, and is used to transport the straightened wire body 10 into the wire profiling device body 13 for profiling.

[0060] Working principle: When in use, before the wire body 10 enters the wire profiling device body 13 for profiling, it first enters the protective cover 1 and passes through multiple sets of straightening rollers 1103 in sequence for straightening operation. When the wire body 10 needs to be placed between the straightening rollers 1103, the electromagnet 406 is powered off. After the electromagnet 406 is powered off, the movable plate 407 can move downward and reset under the action of the first elastic member 404, and abut against the top of the inclined plate 401. At this time, the two U-shaped plates 1101 can be pushed away from each other. At the same time, the second elastic member 303 is compressed, and drives the two straightening rollers 1103 to move away from each other, thereby facilitating the wire body 10 Placing it between the straightening rollers 1103 is more convenient and quick, and can avoid damage to the protective cotton 1104, ensuring its effectiveness and life. Then, the electromagnet 406 is energized. After the electromagnet 406 is energized, it attracts the iron block 405, causing the movable plate 407 to move upward and disengage from the inclined plate 401. At this time, the U-shaped plate 1101 can move closer to each other under the action of the second elastic member 303, and drive the straightening rollers 1103 to move synchronously, so that the protective cotton 1104 is against the wire body 10, and the straightening operation is realized during the transportation process. During the straightening, the wire body 10 can be prevented from running off, ensuring the straightening effect.

[0061] During the straightening process, if the protective cotton 1104 is worn or bulged, the U-shaped plate 1101 and the straightening roller 1103 can move. At the same time, the first push pin 205 can be driven to slide in the first slide groove 203 through the L-shaped block 204, thereby driving the first connecting plate 210 to rotate along the first rotating pin 202, and the wear or bulge of the protective cotton 1104 can be detected by detecting the scale on the second connecting plate 209 indicated by the first connecting plate 210 through the visual sensor 208, thereby facilitating the detection of the wear or bulge of the protective cotton 1104, and an external alarm can be used to remind the operator to perform inspection and replacement to ensure the straightening effect and thus ensure the quality of subsequent pressing.

[0062] When the protective cotton 1104 is worn or bulged, the U-shaped plate 1101 can move. When the U-shaped plate 1101 moves, it can drive the rack 502 to move synchronously, so that the gear 501 rotates, thereby driving the other rack 502 to move, and driving the other U-shaped plate 1101 and the straightening roller 1103 to move, so that the two straightening rollers 1103 in the same group can move synchronously toward or away from each other, avoiding the two straightening rollers 1103 in the same group from deviating from the center position and avoiding the wire body 10 from bending, thereby ensuring the straightening effect and then ensuring the quality of subsequent pressing.

[0063] When the wire body 10 is placed between the straightening rollers 1103, the U-shaped plate 1101 can be moved in the direction close to the protective cover 1. At the same time, when the U-shaped plate 1101 moves, the second pushing pin 607 can be driven to slide along the second slide groove 604 through the first connecting block 606, so as to push the third pushing pin 608 to slide in the third slide groove 605, and then the two cover plates 12 are driven to move away from each other through the second connecting block 603 to avoid interference with the wire body 10. After the straightening is completed, when the work stops, the wire body 10 can be separated from the straightening roller 1103. At this time, the two U-shaped plates 1101 can move closer to each other under the action of the second elastic member 303, and at the same time, the two cover plates 12 can be pushed to move closer to each other and resist each other, so as to seal the interior of the protective cover 1 and protect the protective cotton 1104 from being contaminated by impurities such as dust and water stains, thereby ensuring its use effect and life, and thus ensuring the quality of subsequent pressing.

[0064] After the straightening is completed, when the work is stopped, the electromagnet 406 is first powered off. After the electromagnet 406 is powered off, the movable plate 407 can move downward under the action of the first elastic member 404 and resist against the inclined plate 401, thereby pushing the U-shaped plates 1101 to move away from each other. At this time, the cover 12 can be opened. At the same time, when the movable plate 407 continues to move downward, the lifting plate 803 can be driven to move downward along the gas storage cover 801 through the second connecting rod 804. At this time, the gas storage cover 801 can be temporarily opened. The stored air is squeezed, and at the same time, the first one-way valve is closed and the second one-way valve is opened, so that the air temporarily stored in the air storage cover 801 can enter the fixed tube 901 through the air supply pipe 903 and the connecting pipe 904 and be blown out through the blowing pipe 902. At this time, the impurities on the surface of the protective cotton 1104 can be blown clean. At the same time, under the action of wind, the straightening roller 1103 can be blown to rotate along the first rotating shaft 1102, so that the cleaning efficiency of the surface of the protective cotton 1104 is higher and the effect is better.

[0065] After the cleaning is completed, the electromagnet 406 is energized to move the movable plate 407 upward. After the movable plate 407 is separated from the inclined plate 401, the U-shaped plate 1101 can move closer to each other. At this time, it can drive the cover plate 12 to seal the protective cover 1. When the movable plate 407 continues to move upward, it can drive the lifting plate 803 to move upward through the second connecting rod 804, so that negative pressure is generated in the air storage cover 801. At the same time, the first one-way valve is opened and the second one-way valve is closed. At this time, the air in the protective cover 1 can be drawn in and temporarily stored in the air storage cover 801, thereby reducing the air content in the protective cover 1 and reducing the corrosion of the air to the protective cotton 1104, ensuring its use effect and life, and thus ensuring the quality of subsequent pressing.
