Description

Technical Field

[0001] The present application relates to the technical field of flat wire processing, and in particular to a flat wire punching device. Background Art

[0002] Flat wire, also known as flat wire, flattened wire, flat-angle wire, or ultra-narrow strip, is a shaped metal wire with a roughly rectangular cross-section. As a metal wire with unique properties and a wide range of applications, flat wire plays a vital role in modern industry and electronics.

[0003] A flat wire motor stator is composed of multiple flat wires and a stator core. The winding structure consists of a straight section inserted into the stator core and hairpin ends at each end. During installation of the flat wires and the stator core, variations in wire length and precision in the insertion process can lead to height differences in the hairpin ends of the winding structure. Therefore, cutting equipment is required to ensure consistent heights.

[0004] Regarding the above-mentioned related technologies, the existing cutting equipment only fixes the stator core during cutting. The flat wire is made of thin material and is affected by external factors such as vibration and impact during the punching process, resulting in an unstable punching path and deviation. Utility Model Content

[0005] In order to improve the stability of the punching equipment when cutting flat wires, the present application provides a flat wire punching equipment.

[0006] The flat wire punching equipment provided in this application adopts the following technical solution:

[0007] A flat wire punching device includes a fixing fixture for fixing a flat wire stator, a punching mechanism arranged on opposite sides of the fixing fixture, a sliding mechanism for driving the punching mechanism to slide horizontally toward the fixing fixture, and a lifting mechanism for driving the punching mechanism to rise and fall. The punching mechanism includes a punching bracket, a punching drive member arranged on the punching bracket, a punching head connected to the output shaft of the punching drive member, and a punching sleeve mounted on the punching head. The punching sleeve has a punching through hole for the flat wire to pass through.

[0008] By adopting the above technical solution, when using the above punching equipment for cutting, the flat wire stator is fixed on the fixing fixture, and then the top of the flat wire is inserted into the punching sleeve through the lifting mechanism and the sliding mechanism, and then the punching drive is started to make the punching head punch the part of the flat wire that enters the punching sleeve. Through the setting of the punching sleeve, it is possible to stabilize multiple flat wires in the radial direction, reduce the probability of the flat wire being offset when the punching head is punching, and at the same time have a protective effect on the punching head, thereby increasing the service life of the punching head.

[0009] Optionally, a discharge through hole is provided on the top of one side of the punching sleeve close to the fixing fixture, and the punching bracket is connected to a discharge driving member at the discharge through hole.

[0010] By adopting the above technical solution, the cut materials after punching are discharged from the discharge hole under the action of the discharge drive member. The setting of the discharge hole and the discharge drive member improves the blanking efficiency of punching and reduces the impact of the cut materials on the next punching.

[0011] Optionally, a cover plate is detachably mounted on one side of the punching sleeve corresponding to the punching head, and the cover plate has a heat dissipation through hole communicating with the inner cavity of the punching sleeve.

[0012] By adopting the above technical solution, the heat dissipation through-hole is set to connect the heat dissipation through-hole and the inner cavity of the punching sleeve. After the discharge drive part is started, negative pressure is formed in the punching sleeve, and the outside air enters the punching sleeve, which has a cooling effect on the end of the punching head.

[0013] Optionally, the punching bracket is also provided with multiple groups of clamping components for clamping the punching head, and the multiple groups of clamping components are arranged at intervals along the sliding direction of the punching head. The clamping components include a clamping block and a clamping elastic member connected to the clamping block. The clamping elastic member drives the clamping block to always move toward the punching head.

[0014] By adopting the above technical solution, when the punching head punches the flat wire, the reaction force of the flat wire drives the punching head to move upward. The clamping component is set to have a clamping effect on the punching head, ensuring that the end of the punching head always has a downward trend, further improving the punching stability.

[0015] Optionally, the fixing fixture includes a positioning seat for placing the flat wire stator, a pressing block arranged along the circumference of the positioning seat and used to press the flat wire stator, and a rotation driving member for driving the positioning seat to rotate.

[0016] By adopting the above technical solution, the structural composition of the fixing fixture is disclosed. The flat wire electronic positioning is arranged on the positioning seat, and the top wall end face of the flat wire stator is pressed by the clamping block. After the punching on one side is completed, the positioning seat is driven to rotate by the rotating drive member to perform punching in the other direction.

[0017] Optionally, a fixing assembly for driving the pressing block to rise and fall is provided on the positioning seat, and the fixing assembly includes a pressing rod, a rotating handle rotatably installed on the positioning seat, and a connecting shaft for connecting the pressing rod and the rotating handle. The pressing block has a pressing groove that cooperates with the pressing rod.

[0018] By adopting the above technical solution and setting the fixing assembly, the operator can manually control the lifting and lowering of the pressing block, which is convenient for fixing the flat wire stator on the positioning seat. The fixing assembly has a simple structure, is easy to assemble and operate.

[0019] Optionally, the rotation axis of the rotating handle and the connecting axis are parallel to each other, and the axis of the rotating handle is arranged horizontally.

[0020] By adopting the above technical solution, the axial direction of the rotating handle and the position of the rotating handle and the connecting shaft are defined. When the operator turns the handle downward, the clamping rod and the clamping block move vertically downward. Conversely, the clamping block rises to release the clamping of the flat wire stator.

[0021] Optionally, the lifting mechanism includes a lifting plate for mounting the punching mechanism, a lifting drive connected to the bottom of the lifting plate, and a guide rod for guiding the lifting of the lifting plate.

[0022] By adopting the above technical solution, the structural composition of the lifting mechanism is disclosed, and the lifting mechanism realizes the overall lifting of the punching mechanism, so that the punching through hole can be plugged and matched with the end of the flat wire.

[0023] Optionally, the output shaft of the lifting drive member is provided with a connector, the lifting plate is provided with a through hole for the connector to pass through, and the lifting plate is provided with an abutment edge on the inner wall of the through hole for the connector to position and abut.

[0024] By adopting the above technical solution, the connecting head passes vertically through the through hole and then moves horizontally, so that the abutting edges of the connecting head correspond to each other, so that the abutting edges of the positioning arrangement of the connecting head realize the pre-positioning of the lifting drive member and the lifting plate, which facilitates the subsequent fixed connection between the two.

[0025] Optionally, the sliding mechanism includes a horizontal slide rail provided on the lifting plate, a driving screw arranged parallel to the horizontal slide rail, a driving slider threadedly mounted on the driving screw, and a sliding drive member driving the driving screw, and the punching mechanism and the driving slider are fixedly connected.

[0026] By adopting the above technical solution, the composition of the sliding mechanism is disclosed, and the horizontal movement of the punching mechanism is achieved through the sliding mechanism, which facilitates the punching of through holes corresponding to the flat wire in the vertical direction. The above sliding mechanism has a simple structure and is easy to assemble.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The present application provides a punching sleeve to stabilize multiple flat wires in the radial direction, thereby reducing the probability of flat wires being deflected during punching by the punching head. It also provides protection for the punching head and increases its service life.

[0029] 2. The present application provides a discharge hole and a discharge drive member, so that the cut materials after punching are discharged from the discharge hole under the action of the discharge drive member, thereby improving the punching efficiency;

[0030] 3. The present application can achieve a compacting effect on the punching head by setting a compacting component, thereby ensuring that the end of the punching head always tends to face downward, thereby improving the punching stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 1-6 This application is described in further detail.

[0039] The embodiment of the present application discloses a flat wire punching device.

[0040] Reference Figure 1 A flat wire punching device includes a fixing fixture 1, a punching mechanism 2 arranged on opposite sides of the fixing fixture 1, a sliding mechanism 3 for driving the punching mechanism 2 to slide horizontally, and a lifting mechanism 4 for driving the punching mechanism 2 to lift vertically.

[0041] Reference Figure 1 and Figure 2 The fixture 1 and the lifting mechanism 4 are both fixed to a workbench. The fixture 1 includes a positioning base 11 rotatably mounted on the workbench and for placing the flat wire stator, a pressing block 12 mounted on the positioning base 11 and used to press the flat wire stator, and a rotating drive 13 for driving the positioning base 11 to rotate. The rotating drive 13 is a conventional rotary motor.

[0042] The positioning seat 11 is cylindrical in shape as a whole, and has a positioning groove 111 on its top for positioning the flat wire stator. The clamping blocks 12 are installed on the top of the positioning seat 11 at intervals along the circumferential direction of the axis of the positioning seat 11. A fixing rod 112 that slides with the clamping block 12 is fixedly installed on the top of the positioning seat 11. The clamping block 12 has a sliding through hole 121 that passes through the upper and lower end faces and cooperates with the fixing rod 112. The end of the fixing rod 112 is sleeved with a lubricating sleeve 113 that cooperates with the inner wall of the sliding through hole 121. In this embodiment, three clamping blocks 12 are arranged circumferentially on the positioning seat 11, and the three clamping blocks 12 are evenly spaced along the axis of the positioning seat 11.

[0043] The outer wall of the positioning base 11 is equipped with a fixed assembly 14 that drives the compression block 12 to rise and fall. Fixed assembly 14 includes a lifting rod 141, a rotating handle 142, and a connecting shaft 143. Lifting rod 141 is a U-shaped rod, and the outer wall of the compression block 12 has a compression groove 122 that engages with lifting rod 141. A rotating base 144 is bolted to the positioning base 11, which is rotatably mounted on the rotating handle 142. The axis of rotating base 144 is parallel to the direction of raising and lowering the compression block 12.

[0044] Connecting shaft 143 passes horizontally through rotating handle 142, with the axis of connecting shaft 143 parallel to the rotation axis of rotating base 144. Lifting rod 141 is fixed to both ends of connecting shaft 143, with the entire rotating shaft positioned below the rotation axis. When a worker turns rotating handle 142 downward, lifting rod 141 drives pressing block 12 downward, thereby pressing against the top end face of the flat wire stator.

[0045] Reference Figure 3 The punching mechanism 2 is mounted on opposite sides of the positioning fixture. It comprises a punching bracket 21, a punching driver 22, a punching head 23, and a punching sleeve 24. The punching driver 22 is a conventional electric cylinder, bolted horizontally to the punching bracket 21. The output shaft of the punching driver 22 faces the axis of the positioning seat 11.

[0046] Reference Figure 3 and Figure 4 The punching head 23 is a horizontally arranged rectangular blade with a T-shaped mounting slot on one side of its length for retaining the punching drive 22. A punching sleeve 24 is fixed to the punching bracket 21. The sleeve 24 corresponds to the punching head 23 and defines a punching chamber 241 within which the punching head 23 slides and cuts. The punching head 23 cuts the flat wire within the chamber 241, protecting the punching head 23 while it is capable of cutting, thereby extending its service life.

[0047] In order to allow the flat wire to enter the punching chamber 241, the punching sleeve 24 has a punching hole 242 connecting the inside and the outside at the bottom of the side away from the punching head 23. The punching mechanism 2 is vertically lifted and lowered by the lifting mechanism 4 so that the part of the flat wire to be cut enters the punching chamber 241 through the punching hole 242.

[0048] The punching holes 242 are evenly spaced along the cutting direction of the punching head 23, enabling the punching head 23 to simultaneously punch the portions of the flat wire to be cut on the same side. The top of the punching sleeve 24 also has a discharge hole 243 corresponding to the punching hole 242. A discharge cylinder 25 is mounted at the discharge hole 243 on the punching bracket 21, with a discharge drive 28 mounted on top. In this embodiment, the discharge drive 28 is a suction motor that draws the cut material from the punching chamber 241, enabling discharge.

[0049] A cover plate 26 is mounted on the end of the punching sleeve 24 facing the positioning fixture. The cover plate 26 is bolted to the punching sleeve 24. The bottom of the cover plate 26 has multiple heat dissipation holes 261 that connect to the punching chamber 241. The heat dissipation holes 261 are horizontally arranged strips and are evenly spaced along the height direction.

[0050] To further enhance stability during punching, the punching bracket 21 is equipped with multiple sets of clamping assemblies 27. These sets of clamping assemblies 27 are located atop the punching head 23 and are evenly spaced along the punching direction. In this embodiment, the punching bracket 21 is equipped with three sets of clamping assemblies 27. The punching bracket 21 has a mounting chamber 211 for the clamping assemblies 27. The bottom of the mounting chamber 211 communicates with the punching chamber 241.

[0051] The compression assembly 27 includes a compression spring 271 fixed to the top of the mounting chamber 211 and a compression rod 272 connected to the other end of the compression spring 271. The end of the compression rod 272 extends out of the mounting chamber 211 and corresponds to the top of the punching head 23. The compression spring 271 is a compression spring member of the prior art.

[0052] Reference Figure 5 and Figure 6 The lifting mechanism 4 comprises a lifting plate 41, a lifting drive 42 connected to the bottom of the lifting plate 41, and guide rods 43 for guiding the lifting plate 41. The punching mechanism 2 is fixed to the lifting plate 41 via a sliding mechanism 3. The lifting drive 42 is located at the bottom of the workbench and is a conventional electric cylinder. The guide rods 43 are fixed to the four corners of the bottom of the lifting plate 41. Guide sleeves 44 are installed on the top of the workbench to slide with the guide rods 43.

[0053] A connector 421 is fixed to the end of the lift drive member 42. Connector 421 is cylindrical and has an annular groove 4211 on its sidewall. The lift plate 41 has a through hole 411 for vertical passage of connector 421. Through hole 411 is a strip-shaped hole with an abutment edge 4111 at one end that mates with annular groove 4211.

[0054] The sliding mechanism 3 comprises horizontal rails 31, a drive screw 32, a drive slider 33, and a sliding drive 34. The horizontal rails 31 are fixed to either side of the top of the lifting plate 41 along the punching direction. At least two horizontal sliders 35 are slidably mounted on each horizontal rail 31. The drive screw 32 of the horizontal rails 31 is located between the two horizontal rails 31 and is fixed to the output shaft of the sliding drive 34, which is a combination of a rotary motor and a reducer as is conventionally used. The bottom of the punching bracket 21 and the horizontal sliders 35 are fixedly connected to the drive sliders 33.

[0055] The implementation principle of a flat wire punching device in an embodiment of the present application is as follows: the flat wire stator is positioned and placed on a positioning fixture, and the clamping block 12 is pressed against the top end surface of the flat wire stator through the fixing component 14 to realize fixed loading of the flat wire stator; at the same time, the lifting mechanism 4 and the sliding mechanism 3 on both sides are started, and the end of the flat wire enters the punching chamber 241 through the punching hole 242, and at the same time, the two punching drive members 22 are started, and the punching head 23 cuts the flat wire, and the cut material is discharged through the discharge drive member 28.
