Description

Technical Field

[0001] The present invention belongs to the technical field of motors, and particularly refers to a forming device for motor coils. Background Art

[0002] With the increasing demand for automobiles, the development speed of the automobile industry has gradually accelerated, which has also driven the development of automobile parts production enterprises.

[0003] The demand for automobiles is gradually increasing, and with the improvement of technical standards and quality, the traditional production process of automobile parts can no longer meet the requirements of high quality, high reliability, and mass production in reality.

[0004] As an important equipment in the production process of automotive motor rotor coils, the quality of the forming device for motor coils determines the overall performance of the starter. As a special equipment for processing the rotor windings of starters, it is an essential equipment for enterprises producing automotive starters.

[0005] Currently, the forming devices for motor coils on the market have one thing in common, that is, they are large in size, have poor overall adaptability, and low automation. Especially when discharging after forming, automatic offline discharging cannot be achieved, and additional auxiliary equipment is required for discharging, thus affecting the overall forming efficiency. Summary of the Invention

[0006] The purpose of the present invention is to provide a forming device for motor coils with higher working efficiency.

[0007] The purpose of the present invention is achieved as follows:

[0008] A forming device for motor coils, characterized in that: it includes a feeding mechanism, a stripping and pulling mechanism, a conveying mechanism, a cutting mechanism, and a forming mechanism arranged on the frame in sequence along the horizontal direction. The forming mechanism includes a frame body, an upper die and a lower die that can slide in the frame body. The upper die can reciprocate vertically, and the lower die can reciprocate longitudinally. Limiting blocks are arranged on both the left and right sides of the upper end surface of the frame body. The limiting blocks are provided with limiting grooves that penetrate the limiting blocks horizontally and are open at the rear end. The copper wire is conveyed to the limiting grooves by the conveying mechanism and is cut off by the cutting mechanism. During the longitudinal forward sliding process of the lower die, it can abut against the middle part of the copper wire with both ends placed in the limiting grooves and bend the copper wire until the lower die moves directly below the upper die. At this time, both ends of the copper wire are separated from the corresponding limiting grooves and are close to the left and right side surfaces of the lower die. The upper die and the lower die cooperate to extrude the copper wire attached to the lower die into the required shape.

[0009] In the forming equipment of this motor coil, by setting clamping grooves on both sides of the lower die and matching the clamping grooves with the limiting blocks, automatic demoulding of the copper wire is achieved. The limiting blocks can not only fix the copper wire before forming, but also play a role in demoulding after the copper wire is formed. The structure is simple, the demoulding effect is good, no additional equipment is needed for assistance, the feeding speed is faster, and it is beneficial to improve the overall forming efficiency.

[0010] In the forming equipment of a motor coil mentioned above, convex side edges protrude outward from both the left and right sides of the lower die. The upper side surface of the convex side edge is provided with a clamping groove along the contour of the lower die. A convex front edge protrudes outward from the front side of the lower die. The width of the convex front edge is equal to the width of the clamping groove. The two ends of the convex front edge are respectively connected to the two clamping grooves. The copper wire can be embedded in the clamping groove under the extrusion of the upper die and closely adhere to the upper side surface of the convex front edge.

[0011] The above-mentioned convex side edges can not only limit the two ends of the copper wire, so that the two ends of the formed copper wire can be clamped into the clamping groove to achieve shaping and positioning; but also can abut against the front end surface of the top block during the forward movement of the lower die, avoiding deformation of the convex front edge or the shaping groove due to excessive extrusion, which affects the shaping effect of the copper wire.

[0012] In the forming equipment of a motor coil mentioned above, a groove for the copper wire to pass through is provided on the inner side surface of the limiting block. The groove is communicated with the limiting groove. The inner side surface of the limiting block fits with the left side surface or the right side surface of the lower die. The lower side surface of the limiting block is close to the upper side surface of the convex side edge; the distance between the upper side surface of the convex side edge and the lower side surface of the limiting block located above the convex side edge is less than the difference between the copper wire diameter and the groove depth of the clamping groove.

[0013] The design that the distance between the upper side surface of the convex side edge and the lower side surface of the limiting block located above the convex side edge is less than the difference between the copper wire diameter and the groove depth of the clamping groove can ensure that the limiting block can smoothly hold the two ends of the formed copper wire, so that the copper wire can be smoothly detached from the lower die and automatic feeding is realized.

[0014] In the forming equipment of a motor coil mentioned above, a top block is fixed at the front end of the frame body. A V-shaped shaping groove that penetrates the top block in the vertical direction is provided on the rear end surface of the top block. The front end of the lower die is in a V shape that matches the shaping groove. The front end of the lower die can extend into the shaping groove and extrude the middle part of the copper wire into a V shape. The front side surface of the convex front edge matches the shape of the V-shaped groove and can abut against the groove wall of the V-shaped groove. The front end surface of the convex side edge can abut against the rear end surface of the top block.

[0015] In the above-mentioned forming device for an electric motor coil, the upper end surface of the front convex edge is wavy, being high in the middle and low on both sides. A convex block is formed at the front end of the upper die. The front side surface of the convex block cooperates with the V-shaped groove. The lower end part of the convex block can extend into the gap between the front end surface of the lower die and the groove wall of the V-shaped groove, and the shape of the lower end surface of the convex block matches the shape of the upper end surface of the front convex edge. The convex block can press and fix the copper wire on the front convex edge together with the upper die.

[0016] In the above-mentioned forming device for an electric motor coil, an inclined hopper is fixed at the lower end of the frame body. The upper end of the hopper is located directly below the upper die and on the lower side of the lower die. The lower end of the hopper extends out from the side of the frame. A storage box for collecting copper wire is provided on the lower side of the lower end of the hopper.

[0017] In the above-mentioned forming device for an electric motor coil, the feeding mechanism includes a rectangular vertical plate and a horizontal plate. The length directions of both the vertical plate and the horizontal plate are parallel to the moving direction of the copper wire. At least three first guide wheels and second guide wheels are provided on both the vertical plate and the horizontal plate. The first guide wheels and the second guide wheels are both arranged at intervals along the length direction of the vertical plate and the horizontal plate. The first guide wheels and the second guide wheels can both be adjusted and fixed along the width direction of the vertical plate or the horizontal plate where they are located. The first guide wheels and the second guide wheels are arranged opposite to each other and staggeredly.

[0018] This feeding mechanism clamps and straightens the copper wire in the vertical direction through the vertical plate, and clamps and straightens the copper wire in the horizontal direction through the horizontal plate. The adjustable first guide wheels and second guide wheels can make the clamping and straightening effects better by adjusting their positions.

[0019] In the above-mentioned forming device for an electric motor coil, the horizontal plate is arranged between the stripping and pulling mechanism and the vertical plate. An outlet guide ring is provided on the side of the horizontal plate close to the stripping and pulling mechanism, and an inlet guide ring is provided on the side of the vertical plate far from the horizontal plate.

[0020] The designs of the above-mentioned inlet guide ring and outlet guide ring can not only make the inlet and outlet more smooth, but also avoid scratching the copper wire during the inlet or outlet process, affecting the use effect.

[0021] The working principle of the motor coil forming equipment is as follows: first, the copper wire enters the stripping mechanism from the winding rack through the feeding mechanism, and the stripping mechanism strips and removes the paint skin on the copper wire, and then the copper wire is transported to the forming mechanism through the cutting mechanism in sections through the conveying mechanism. When the copper wire completely falls into the forming mechanism, the cutting mechanism works to cut the copper wire. At this time, the two ends of the copper wire are respectively located in the limiting grooves of the limiting blocks. The driving part drives the lower die to move forward in the longitudinal direction, so that the front end of the lower die is connected with the middle part of the copper wire and drives the copper wire to continue to move forward, so that the two ends of the copper wire are separated from the limiting groove and are guided by the groove to be tightly attached to the left and right side walls of the lower die. The lower die continues to move forward until the front convex edge of the lower die abuts against the molding groove of the top block. At this time, the middle part of the copper wire is squeezed and fixed between the front side surface of the lower die and the molding groove of the top block and is in a V shape. Then the upper mold moves downward under the action of the driving member, and the convex block of the upper mold is inserted into the gap formed between the lower mold and the top block until the copper wire is squeezed and fixed on the upper side of the front convex edge. At this time, the middle part of the copper wire is squeezed in the vertical direction into the same shape as the upper side of the front convex edge or the lower side of the convex block. At the same time, the copper wires on the left and right sides of the lower mold will be pressed down during the downward movement of the upper mold so that they are embedded in the grooves of the side convex edges; then the upper mold moves upward, and at the same time, the lower mold moves backward along the longitudinal direction to block the limit block. After the two ends of the formed copper wire hit the front side of the limit block, they are blocked and cannot continue to move backward with the lower mold. When the lower mold continues to move backward and moves to the rear side of the limit block, the formed copper wire will separate from the lower mold in this process and fall to the upper end of the hopper located below and fall into the storage box along the hopper, completing the entire copper wire forming process.

[0022] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0023] In the forming equipment of the motor coil, slots are arranged on both sides of the lower die, and the slots are matched with the limit blocks to realize automatic demoulding of the copper wire. The limit blocks can not only play the role of fixing the copper wire before forming, but also play the role of demoulding after the copper wire is formed. The structure is simple, the demoulding effect is good, no additional equipment is required for assistance, the material feeding speed is faster, and it is beneficial to improve the overall forming efficiency.

Specific embodiments

[0030] The present invention will be further described below with specific embodiments in conjunction with the accompanying drawings. Refer to Figure 1 —5:

[0031] The forming device of the motor coil includes a feeding mechanism 1, a peeling mechanism 2, a conveying mechanism 3, a cutting mechanism 4, and a forming mechanism 5 arranged in sequence along the transverse direction on the machine frame 6. The forming mechanism 5 includes a frame 51, an upper die 52 and a lower die 53 slidably arranged in the frame 51. The upper die 52 can reciprocate vertically, and the lower die 53 can reciprocate longitudinally. Limiting blocks 54 are arranged on both the left and right sides of the upper end surface of the frame 51. The limiting blocks 54 are provided with limiting grooves 541 that penetrate the limiting blocks 54 transversely and are open at the rear end. The copper wire 7 is conveyed into the limiting groove 541 by the conveying mechanism 3 and is cut off by the cutting mechanism 4. During the longitudinal forward sliding of the lower die 53, it can abut against the middle of the copper wire 7 with both ends placed in the limiting groove 541 and bend the copper wire 7 until the lower die 53 moves directly below the upper die 52. At this time, both ends of the copper wire 7 are separated from the corresponding limiting grooves 541 and are close to the left and right side surfaces of the lower die 53. The upper die 52 and the lower die 53 cooperate to extrude the copper wire 7 attached to the lower die 53 into the required shape. In the forming device of the motor coil, by arranging clamping grooves 532 on both sides of the lower die 53 and cooperating the clamping grooves 532 with the limiting blocks 54, automatic demolding of the copper wire 7 is realized. The limiting blocks 54 can not only play the role of fixing the copper wire 7 before forming, but also play the role of demolding after the copper wire 7 is formed. The structure is simple, the demolding effect is good, no additional equipment is required for assistance, the feeding speed is faster, and it is beneficial to improve the overall forming efficiency.

[0032] Such as Figures 2 - 4As shown in the figure, both the left and right sides of the lower die 53 bulge outwards to form side convex edges 531. The upper side surface of the side convex edge 531 is provided with a clamping groove 532 along the contour of the lower die 53. The front side of the lower die 53 bulges outwards to form a front convex edge 533. The width of the front convex edge 533 is equal to the width of the clamping groove 532. Both ends of the front convex edge 533 are respectively connected to the two clamping grooves 532. The copper wire 7 can be embedded in the clamping groove 532 under the extrusion of the upper die 52 and closely adhere to the upper side surface of the front convex edge 533. A groove 542 for the copper wire 7 to pass through is provided on the inner side surface of the limit block 54. The groove 542 communicates with the limit groove 541. The inner side surface of the limit block 54 fits with the left or right side surface of the lower die 53. The lower side surface of the limit block 54 is close to the upper side surface of the side convex edge 531. The distance between the upper side surface of the side convex edge 531 and the lower side surface of the limit block 54 located above the side convex edge 531 is less than the difference between the diameter of the copper wire 7 and the depth of the clamping groove 532.

[0033] The above-mentioned side convex edge 531 can not only limit the two ends of the copper wire 7, so that the two ends of the formed copper wire 7 can be clamped into the clamping groove 532 to achieve shaping and positioning; but also can abut against the front end surface of the top block 55 during the forward movement of the lower die 53, avoiding deformation of the front convex edge 533 or the shaping groove 551 due to excessive extrusion, which affects the shaping effect of the copper wire 7; the design that the distance between the upper side surface of the above-mentioned side convex edge 531 and the lower side surface of the limit block 54 located above the side convex edge 531 is less than the difference between the diameter of the copper wire 7 and the depth of the clamping groove 532 can ensure that the limit block 54 can smoothly hold the two ends of the formed copper wire 7, enabling the copper wire 7 to smoothly disengage from the lower die 53 and realizing automatic blanking.

[0034] Furthermore, a top block 55 is fixed at the front end of the frame body 51. A V-shaped shaping groove 551 that penetrates the top block 55 in the vertical direction is provided on the rear end surface of the top block 55. The front end of the lower die 53 is in a V-shape that matches the shaping groove 551. The front end of the lower die 53 can extend into the shaping groove 551 and squeeze the middle part of the copper wire 7 into a V-shape. The front side surface of the front convex edge 533 matches the shape of the V-shaped groove and can abut against the groove wall of the V-shaped groove. The front end surface of the side convex edge 531 can abut against the rear end surface of the top block 55; the upper end surface of the front convex edge 533 is high in the middle and low on both sides, showing a wavy shape. A convex block 521 is formed at the front end of the upper die 52. The front side surface of the convex block 521 matches the V-shaped groove. The lower end of the convex block 521 can extend into the gap between the front end surface of the lower die 53 and the groove wall of the V-shaped groove, and the shape of the lower end surface of the convex block 521 matches the shape of the upper end surface of the front convex edge 533. The convex block 521 can press and fix the copper wire 7 on the front convex edge 533 along with the upper die 52.

[0035] Furthermore, an inclined hopper is fixed at the lower end of the frame body 51. The upper end of the hopper is located directly below the upper die 52 and below the lower die 53. The lower end of the hopper extends out from the side of the frame 6. A storage box for collecting the copper wire 7 is provided below the lower end of the hopper.

[0036] As Figure 5 shown, the feeding mechanism 1 includes a rectangular vertical plate 11 and a horizontal plate 12. The length directions of the vertical plate 11 and the horizontal plate 12 are both parallel to the moving direction of the copper wire 7. At least three first guide wheels 13 and second guide wheels 14 are provided on both the vertical plate 11 and the horizontal plate 12. The first guide wheels 13 and the second guide wheels 14 are both arranged at intervals along the length direction of the vertical plate 11 and the horizontal plate 12. The first guide wheels 13 and the second guide wheels 14 can both be adjusted and fixed along the width direction of the corresponding vertical plate 11 or horizontal plate 12. The first guide wheels 13 and the second guide wheels 14 are opposite and staggered; the horizontal plate 12 is arranged between the peeling and pulling mechanism 2 and the vertical plate 11. An outlet guide ring 16 is provided on one side of the horizontal plate 12 close to the peeling and pulling mechanism 2, and an inlet guide ring 15 is provided on one side of the vertical plate 11 away from the horizontal plate 12. The feeding mechanism 1 clamps and straightens the copper wire 7 in the vertical direction through the vertical plate 11, and clamps and straightens the copper wire 7 in the horizontal direction through the horizontal plate 12. The adjustable first guide wheels 13 and second guide wheels 14 can adjust the positions of the two to make the clamping and straightening effects better; the designs of the above inlet guide ring 15 and outlet guide ring 16 can not only make the feeding and discharging smoother, but also avoid scratching the copper wire 7 during the feeding or discharging process, affecting the use effect.

[0037] When the motor coil forming device is working, first, the copper wire 7 enters the stripping mechanism 2 from the winding rack through the feeding mechanism 1, and the stripping mechanism 2 strips and removes the paint skin of the copper wire 7, and then the copper wire 7 is transported to the forming mechanism 5 through the cutting mechanism 4 by the conveying mechanism 3. When the copper wire 7 completely falls into the forming mechanism 5, the cutting mechanism 4 works to cut the copper wire 7. At this time, the two ends of the copper wire 7 are respectively located in the limiting groove 541 of the limiting block 54, and the driving member drives the lower mold 53 along The lower die 53 moves forward longitudinally, so that the front end of the lower die 53 is in contact with the middle of the copper wire 7 and drives the copper wire 7 to continue to move forward, so that the two ends of the copper wire 7 are separated from the limiting groove 541 and are closely attached to the left and right side walls of the lower die 53 under the guidance of the groove 542. The lower die 53 continues to move forward until the front convex edge 533 of the lower die 53 abuts against the shaping groove 551 of the top block 55. At this time, the middle part of the copper wire 7 is squeezed and fixed between the front side surface of the lower die 53 and the shaping groove 551 of the top block 55 and forms a V shape. As the upper mold 52 moves downward under the action of the driving member, the protrusion 521 of the upper mold 52 is inserted into the gap formed between the lower mold 53 and the top block 55 until the copper wire 7 is squeezed and fixed to the upper side of the front convex edge 533. At this time, the middle part of the copper wire 7 is squeezed in the vertical direction into the same shape as the upper side of the front convex edge 533 or the lower side of the protrusion 521. At the same time, during the downward movement of the upper mold 52, the copper wires 7 located on the left and right sides of the lower mold 53 are also pressed downward to be embedded in the grooves 532 of the side convex edge 531. Then the upper mold 52 moves upward, and at the same time the lower mold 53 moves backward in the longitudinal direction to be blocked by the limit block 54. The two ends of the formed copper wire 7 are blocked after hitting the front side of the limit block 54 and cannot continue to move backward with the lower mold 53. When the lower mold 53 continues to move backward and moves to the rear side of the limit block 54, the formed copper wire 7 will be separated from the lower mold 53 in this process and fall to the upper end of the hopper below and fall into the storage box along the hopper, completing the entire copper wire 7 forming process.

[0038] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
