Description

Technical Field

[0001] This utility model relates to the technical field of copper wire processing equipment for motors, and specifically to a fully automatic copper wire shaping device. Background Technology

[0002] The stator windings of an electric motor consist of copper wire wound into stator slots. The copper wire used in motors is mainly divided into round copper wire and flat copper wire, primarily distinguished by the motor's power rating. High-power motors mainly use flat copper wire, which is typically cut and then shaped into a U-shaped connecting wire. The stamping process of flat copper wire generally involves two stages. The first stage is the forming of the U-shaped 2D copper wire. Then, to achieve the final 3D curved shape of the crown end, the U-shaped 2D copper wire formed in the first stage is placed into a 3D forming mold. The upper and lower molds are then closed to complete the final stamping of the flat copper wire.

[0003] In the 3D forming process of flat copper wire, the stability and consistency of the copper wire position plays a key role in the precision of the final product. Therefore, a forming mechanism that can ensure the stability of the flat copper wire position and has deformation space is needed to adapt to automated production. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fully automatic copper wire shaping device.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A fully automatic copper wire shaping device includes a frame and an upper drive module, a shaping module, and a lower drive module arranged sequentially from top to bottom within the frame. The shaping module includes an upper mold base, a lower mold base, and a contouring pressure rod. The upper mold base is fixed to the frame, and the lower mold base is located on top of the lower drive module and is driven by it to move vertically relative to the upper mold base to close or open the mold. A shaping space is formed between the end faces of the upper and lower mold bases for shaping the workpiece to be pressed. The contouring pressure rod is vertically inserted into the upper mold base, and its top is fixed to the bottom of the upper drive module and is driven by it to move vertically relative to the lower mold base. The contouring pressure rod moves synchronously with the lower mold base relative to the upper mold base, forming a positioning mechanism for limiting the workpiece to be pressed.

[0007] Preferably, at least one front limiting block is vertically arranged at the front end of the top face of the lower mold base, and side limiting blocks are vertically symmetrically arranged on both sides of the lower mold base. The front limiting block and the side limiting blocks form a limiting space adapted to the workpiece to be pressed. The contouring pressure rod includes two positioning rods with a spacing adapted to the width of the workpiece to be pressed. The bottom of the two positioning rods limits the two sides of the workpiece to be pressed within the limiting space.

[0008] Preferably, a limiting groove matching the bottom of the contouring pressure rod is formed between the two side limiting blocks, a first guide slope is formed on the opposing inner surfaces between the two side limiting blocks, a first slope matching the first guide slope is formed on the outer bottom of the positioning rod, and the positioning rod slides into the limiting groove to position the workpiece to be pressed.

[0009] Preferably, the top surface of the lower mold base is a concave contouring surface, and the front end of the bottom surface of the upper mold base forms a contouring convex surface that matches the contouring concave surface. The front end limiting block is fixed on the contouring concave surface, and the contouring convex surface is provided with an insertion hole that matches the front end limiting post. When the lower mold base and the upper mold base are closed, the limiting post is inserted into the insertion hole, and the contouring convex surface and the contouring concave surface engage to form an end-shaping space for shaping the end of the workpiece to be pressed.

[0010] Preferably, the tops of the two positioning rods are respectively connected to the bottom of the upper drive module via a cylinder, and the bottom surface of the positioning rod is an inclined second slope that matches the contoured concave surface.

[0011] Preferably, clamps are symmetrically arranged on both sides of the rear end of the upper mold base. Each clamp includes a fixed limiting post fixed to the upper mold base and a movable limiting post horizontally slidable on the upper mold base. A side shaping space is formed between the fixed limiting post and the movable limiting post for shaping the side of the workpiece to be pressed. A driving mechanism is formed at the center of the upper mold base and the lower mold base, which can drive the movable limiting post to move horizontally relative to the fixed limiting post. When the lower mold base and the upper mold base are closed, the driving mechanism drives the clamps to close. When the lower mold base and the upper mold base are opened, the driving mechanism drives the clamps to open.

[0012] Preferably, the driving mechanism includes an upper pressure block vertically slidably disposed at the center of the upper mold base and a lower pressure block disposed on the lower mold base. The top of the upper pressure block has a driving inclined block. The movable limiting post is an inverted L-shape, and the two movable limiting posts are symmetrically disposed opposite each other. The bottom of its inner end forms a second guide inclined surface that slides against the driving inclined block. A return spring is disposed on the outer side of each movable limiting post. When the lower mold base and the upper mold base are closed, the lower pressure block abuts against the upper pressure block and drives the upper pressure block to move upward, so that the driving inclined block drives the two movable limiting posts to move inward synchronously, thereby closing the clamp. When the lower mold base and the upper mold base are opened, the return spring pulls the two movable limiting posts to move outward synchronously, thereby opening the clamp.

[0013] Preferably, the bottom of the outer side wall of the fixed limiting post has a notch that matches the side of the workpiece to be pressed, and the top side wall of the notch is an inclined third slope, the slope of which matches the contoured convex surface.

[0014] Preferably, the upper drive module and the lower drive module have the same structure and are arranged opposite to each other. The upper drive module and the lower drive module each include a servo motor, a planetary reducer, a coupling, a bearing housing, a ball screw, and a linear guide rail connected to each other. A set of inductive switches is provided on the frame. The inductive switches include at least an upper limit position inductive switch, a zero point position inductive switch, and a lower limit position inductive switch.

[0015] Preferably, the upper mold base has an upper mounting plate at its top, and the frame is provided with a first slot that matches the upper mounting plate, the upper mounting plate being slidably inserted into the first slot; the lower mold base also has a lower mounting plate at its bottom, the lower drive module has a second slot that matches the lower mounting plate at its top, the lower mounting plate being slidably inserted into the second slot; the lower drive module has a third slot at its bottom that matches the top of the contouring pressure rod, the top of the contouring pressure rod being inserted into the third slot.

[0016] The beneficial effects of this utility model are mainly reflected in:

[0017] 1. A movable contouring pressure bar is set in the shaping module to form an effective positioning mechanism with the lower mold base. The contouring pressure bar moves synchronously with the lower mold base to ensure the stability and consistency of the copper wire position, ensure the shaping accuracy of the copper wire, and realize the automated processing flow of positioning and shaping.

[0018] 2. The upper mold base and the lower mold base form end shaping space and side shaping space respectively for the front end and side of the copper wire, so that the side of the copper wire deforms synchronously with its end, thereby reducing the bending effect caused by the deformation of the copper wire end on its side and ensuring the straight extension of both sides of the copper wire.

[0027] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0029] like Figures 1 to 7 As shown, this utility model discloses a fully automatic copper wire shaping device, including a frame 1 and an upper drive module, a shaping module, and a lower drive module arranged sequentially from top to bottom within the frame 1. The shaping module includes an upper mold base 201, a lower mold base 301, and a contouring pressure rod 4. The upper mold base 201 is fixed to the frame 1, and the lower mold base 301 is disposed on the top of the lower drive module and driven by it to move vertically relative to the upper mold base 201, thereby interacting with the upper mold base 201. 1. When the mold is closed or opened, a shaping space is formed between the end faces of the upper mold base 201 and the lower mold base 301 for shaping the workpiece 5 to be pressed; the contouring pressure rod 4 is vertically inserted into the upper mold base 201, and the top of the contouring pressure rod 4 is fixed to the bottom of the upper drive module and driven by it to move vertically relative to the lower mold base 301. The contouring pressure rod 4 moves synchronously with the lower mold base 201 relative to the upper mold base 201, forming a positioning mechanism for limiting the workpiece 5 to be pressed.

[0030] This solution sets a movable contouring pressure rod 4 in the shaping module to form an effective positioning mechanism with the lower mold base 301. The contouring pressure rod 4 moves synchronously with the lower mold base 301 to ensure the stability and consistency of the position of the workpiece 5 to be pressed, and to ensure the shaping accuracy of the workpiece 5 to be pressed.

[0031] Specifically, the workpiece 5 to be pressed in this solution is preferably a U-shaped copper wire, which includes a U-shaped end and two straight wire ends extending on both sides. In other feasible embodiments, the workpiece 5 to be pressed can also be other U-shaped workpieces that need to be shaped. For ease of understanding, the following description uses a U-shaped copper wire as an example.

[0032] To facilitate the placement of the workpiece 5 to be pressed, at least one front-end limiting block 303 is vertically arranged at the front end of the top face of the lower mold base 301. Preferably, two symmetrically arranged front-end limiting blocks 303 are provided on the lower mold base 301 to adapt to the U-shaped end of the workpiece 5 to be pressed. Side limiting blocks 304 are vertically and symmetrically arranged on both sides of the lower mold base 301. The front-end limiting blocks 303 and the side limiting blocks 304 form a limiting space adapted to the U-shaped end of the workpiece 5 to be pressed. The contouring pressure rod 4 includes two positioning rods 401 with a spacing adapted to the width of the workpiece 5 to be pressed. The bottom of the two positioning rods 401 limits the two sides of the workpiece 5 to be pressed within the limiting space. The adaptability of the limiting space to the U-shaped end of the workpiece 5 to be pressed can ensure the stable placement of the workpiece 5 to be pressed without lateral displacement.

[0033] The U-shaped end of the workpiece 5 to be pressed needs to be bent and shaped. The bottom of the positioning rod 401 positions the workpiece 5 to be pressed without affecting the deformation of its U-shaped end by limiting the U-shaped end and the bend on its side of the workpiece 5.

[0034] Furthermore, a limiting groove matching the bottom of the contouring pressure rod 4 is formed between the two side limiting blocks 304, allowing the positioning rod 401 to move within the limited range of the side limiting blocks 304, ensuring that the positioning rod 401 is located within the limiting groove. A first guide slope 3041 is formed on the opposing inner surfaces of the two side limiting blocks 304, and a first slope 402 matching the first guide slope 3041 is formed on the outer bottom of the positioning rod 401, facilitating the sliding of the positioning rod 401 into the limiting groove and positioning the workpiece 5 to be pressed. To facilitate alignment between the side limiting blocks 304 and the positioning rod 401, a recessed strip 3011 is provided on the side of the lower mold base 301 to facilitate the side limiting blocks 304 being fixed in any position. This structure can guide and limit the position of the positioning rod 401, ensuring that the bottom of the positioning rod 401 is aligned with the workpiece 5 to be pressed, thus achieving effective limiting.

[0035] like Figure 2-6 As shown, the top surface of the lower mold base 301 is a concave contoured surface 302, and the front end of the bottom surface of the upper mold base 201 forms a contoured convex surface 202 that matches the contoured concave surface 302. The contoured convex surface 202 and the contoured concave surface 302 engage to form an end-shaping space for shaping the end of the workpiece 5 to be pressed. The front-end limiting block 303 is fixed on the contoured concave surface 302. In order to allow the front-end limiting block 303 to be positioned, the contoured convex surface 202 is provided with an insertion hole 203 that matches the front-end limiting post 303. When the lower mold base 301 and the upper mold base 201 are closed, the limiting post 303 is inserted into the insertion hole 203.

[0036] Furthermore, the tops of the two positioning rods 401 are respectively connected to the bottom of the upper drive module via a cylinder 404 to ensure the consistency and stability of the overall downward pressure of the contouring pressure rod 4 and avoid imbalance on both sides. The bottom surface of the positioning rod 401 is an inclined second slope 403, which matches the contouring concave surface 302, so that the bottom of the positioning rod 401 is always in contact with the surface of the workpiece 5 to be pressed, thereby ensuring the accuracy and stability of the positioning of the positioning rod 401 in positioning the workpiece 5 to be pressed.

[0037] like Figure 3 and Figure 7 As shown, the U-shaped shape of the workpiece 5 to be pressed causes the side of the press to bend synchronously after the U-shaped end is bent and shaped. In order to eliminate the influence of the deformation of the end of the workpiece 5 on the straightness of its two sides, clamps for shaping the side of the workpiece 5 to be pressed are symmetrically arranged on both sides of the rear end of the upper mold base 201. Each clamp includes a fixed limiting post 204 fixed on the upper mold base 201 and a movable limiting post 205 horizontally slidably arranged on the upper mold base 201. A side shaping space is formed between the column 204 and the movable limiting column 205 for shaping the side of the workpiece 5 to be pressed. The upper mold base 201 and the lower mold base 301 are provided with a driving mechanism at their center, which can drive the movable limiting column 205 to move horizontally relative to the fixed limiting column 204. When the lower mold base 301 and the upper mold base 201 are closed, the driving mechanism drives the clamp to close. When the lower mold base 301 and the upper mold base 201 are opened, the driving mechanism drives the clamp to open.

[0038] The driving mechanism includes an upper pressure block 206 vertically slidably disposed at the center of the upper mold base 201 and a lower pressure block 305 disposed on the lower mold base 301. The top of the upper pressure block 206 has a driving inclined block 2061. The movable limiting post 205 is an inverted L-shape, and two movable limiting posts 205 are symmetrically arranged. A second guide inclined surface 2051 is formed at the bottom of its inner end, slidingly abutting against the driving inclined block 2061. Each movable limiting post 205 has an outer side... A reset spring 207 is provided. When the lower mold base 301 and the upper mold base 201 are closed, the lower pressure block 305 abuts against the upper pressure block 206 and drives the upper pressure block 206 to move upward, so that the driving inclined block 2061 drives the two movable limiting posts 205 to move inward synchronously, thereby closing the clamp. When the lower mold base 301 and the upper mold base 201 are opened, the reset spring 207 pulls the two movable limiting posts 205 to move outward synchronously, thereby opening the clamp. The driving mechanism is formed by the lower pressing block 305 and the upper pressing block 206 abutting each other, so that the driving mechanism moves synchronously with the mold closing of the upper mold base 201 and the lower mold base 301. This ensures that the end shaping space formed by the contouring convex surface 202 and the contouring concave surface 302, and the side shaping space formed by the fixed limiting post 204 and the movable limiting post 205 are formed synchronously. This allows the end and both sides of the workpiece 5 to be pressed to be shaped synchronously, which not only improves efficiency but also ensures the consistency and accuracy of the shaping.

[0039] Furthermore, the bottom of the outer wall of the fixed limiting post 204 has a notch that matches the side of the workpiece 5 to be pressed. The space between the notch and the inner side of the movable limiting post 205 is a side shaping space for shaping the side of the workpiece 5 to be pressed. The two sides of the workpiece 5 to be pressed are engaged in the side shaping space, and as the upper mold base 201 and the lower mold base 301 close, the clamps gradually close, so that the two sides of the workpiece 5 to be pressed will fit tightly against the inner wall of the side shaping space to complete the side shaping. The outer walls of the two sides of the lower mold base 301 are provided with guide grooves that match the movable limiting post 205. The top sidewall of the notch is an inclined third slope 2041, and the slope of the third slope 2041 matches the contour convex surface 202 to ensure that the tilting deformation angle generated after the side of the workpiece 5 to be pressed abuts against the third slope 2041 matches the bending angle of its end.

[0040] like Figure 1As shown, the upper drive module and the lower drive module have the same structure and are arranged opposite to each other. Both the upper drive module and the lower drive module include a servo motor 501, a planetary reducer 502, a coupling 503, a bearing seat 504, a ball screw 505, and a linear guide 506 connected to each other. The upper drive module and the lower drive module are conventional drive modules, which are existing technologies and are not the focus of this solution, so they will not be described in detail here.

[0041] To ensure the driving accuracy and safety of the upper and lower drive modules, a set of inductive switches 507 is installed on the frame 1. Each inductive switch 507 includes at least an upper limit switch, a zero-point switch, and a lower limit switch. These switches are arranged sequentially from top to bottom. The sensing element of each switch 507 is fixed to a slider on the ball screw 505 and moves synchronously with the slider to indicate the driving distance of the upper and lower drive modules. The zero-point switch senses the start-up of the drive module and the lower drive module. The upper and lower limit switches limit the vertical movement of the upper and lower drive modules. When either the upper or lower limit switch is triggered, it indicates that the upper and lower drive modules have moved excessively and require a shutdown for inspection. The arrangement of a set of inductive switches 507 can ensure the safe operation of the upper drive module and the lower drive module, and avoid excessive pressure damage to the molding module.

[0042] Furthermore, the upper mold base 201 has an upper mounting plate 208 at its top, and the frame 1 is provided with a first slot that matches the upper mounting plate 208, the upper mounting plate 208 being slidably inserted into the first slot; the lower mold base 301 also has a lower mounting plate 306 at its bottom, the lower drive module has a second slot that matches the lower mounting plate 306 at its top, the lower mounting plate 306 being slidably inserted into the second slot, the lower mounting plate 306 being slidably inserted into the second slot 200; the lower drive module is provided with a third slot 300 at its bottom that matches the top of the contouring pressure rod 4, the top of the contouring pressure rod 4 being inserted into the third slot 300. This structure allows for convenient connection, installation, disassembly, and replacement of the upper mold base 201 with the frame, the lower mold base 301 with the lower drive module, and the contouring pressure rod 4 with the upper drive module via quick-release mechanisms. This facilitates the overall replacement of the shaping module and allows for the replacement of different specifications of shaping modules to shape workpieces 5 with different shaping widths and depths, providing overall flexibility and ease of use.

[0043] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0044] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
