Description

Technical Field

[0001] This utility model relates to the technical field of flat wire forming equipment, and in particular to a line leveling device. Background Technology

[0002] Currently, corrugated flat wire stators are mainly used in high-efficiency, high-power-density motors, such as high-speed motors, electric vehicle drive motors, and wind turbines. Compared to traditional round wire winding stators, corrugated flat wire stators use corrugated flat wire windings. The cross-section of this winding is flat, allowing the winding to be more tightly wrapped around the iron core, thus reducing the voids in the stator core and improving the motor's efficiency and power density. During the flat wire forming process, after the flat wire is pulled from the coil, it undergoes straightening and cutting processes to form segmented flat wires. Due to the relatively long length of the flat wire, it is still prone to deformation before being fed into the forming equipment. Therefore, a flattening device is used to flatten the flat wire before forming. Existing flattening devices use clamping mechanisms to hold both ends of the flat wire and then pull the flat wire in opposite directions to straighten it. However, because the clamping mechanism and the flat wire have rigid contact, the coating of the flat wire is easily damaged during the dragging process after clamping, affecting the quality of the flat wire and causing material waste.

[0022] like Figures 1 to 6As shown, the line leveling device 400 provided in this embodiment includes a first pulling device 410 and a second pulling device 420 arranged at intervals along a first direction D1 (D1 direction shown in the figure, hereinafter referred to as the first direction D1). The first pulling device 410 includes: a first pulling base 411; a first wire carrier 412 disposed on the first pulling base 411, the surface of the first wire carrier 412 having at least one first wire groove 4121 for inserting the end of the flat wire 90 and extending along the first direction D1; a first wire pressing mechanism 413 disposed on the first pulling base 411 and used to press the end of the flat wire 90 against the first wire carrier 412; and a first pulling drive mechanism 414 connected to the first pulling base 411 and used to drive the first pulling base 411 along the first direction D1. The first pulling device 420 includes: a second pulling base 421, which is arranged side by side and spaced apart from the first pulling base 411 in the first direction D1; a second wire carrier 422, which is disposed on the second pulling base 421, and at least one second wire groove 4221 is formed on the surface of the second wire carrier 422 for inserting the end of the flat wire 90 and extending along the first direction D1; a second wire pressing mechanism 423, which is disposed on the second pulling base 421 and is used to press the end of the flat wire 90 against the second wire carrier 422; and a second pulling drive mechanism 424, which is connected to the second pulling base 421 and is used to move the second pulling base 421 along the first direction D1; the second wire pressing mechanism 423 includes a non-metallic contact block 425 for contacting the flat wire 90.

[0023] The aforementioned line leveling device 400 includes a first pulling device 410 and a second pulling device 420 arranged at intervals. The first pulling device 410 includes a first pulling base 411, a first wire carrier 412 having a first wire groove 4121, a first pressing mechanism 413 for pressing the end of the flat wire 90 onto the first wire carrier 412, and a first pulling drive mechanism 414 for moving the first pulling base 411 along a first direction D1. The first wire carrier 412 and the first pressing mechanism 413 respectively support... On the first wire carrier 412; the second pulling device 420 includes a second pulling base 421, a second wire carrier 422 having a second wire groove 4221, a second wire pressing mechanism 423 for pressing the end of the flat wire 90 onto the second wire carrier 422, and a second pulling drive mechanism 424 for moving the second pulling base 421 along a first direction D1. The second wire carrier 422 and the second wire pressing mechanism 423 are respectively supported on the second wire carrier 422; the second wire pressing mechanism 423 includes a non-metallic material and The contact block 425 is used to contact the flat wire 90. Thus, the first pulling device 410 supports the end of the flat wire 90 via the first wire carrier 412, and the first pressing mechanism 413 presses the flat wire 90 onto the first wire carrier 412, thereby clamping the end of the flat wire 90 together with the first wire carrier 412. The second pulling device 420 supports the other end of the flat wire 90 via the second wire carrier 422, and the second pressing mechanism 423 presses the flat wire 90 onto the second wire carrier 422, thereby clamping the end of the flat wire 90 together with the first wire carrier 412. The flat wire 90 is held by two clamps, and the first wire carrier 412 and the second wire carrier 422 are driven to move in opposite directions by the first pulling drive mechanism 414 and the second pulling drive mechanism 424 respectively, so as to flatten the flat wire 90. In the second wire pressing mechanism 423, a non-metallic contact block 425 is used to contact the flat wire 90. During the flattening process, the contact block 425 and the flat wire 90 can generate relative displacement, which can avoid the paint wear of the flat wire 90 during the pulling process, thereby ensuring product quality.

[0024] See Figure 1The line leveling device 400 provided in this embodiment (disposed on one side of the frame and located between the first forming device and the second forming device) includes a first pulling device 410 and a second pulling device 420. The first pulling device 410 and the second pulling device 420 are both installed on a leveling support frame (not shown in the figure) (or can be directly installed on the frame). The first pulling device 410 and the second pulling device 420 are arranged at intervals along the first direction D1. The first pulling device 410 includes a first pulling base 411 (located in the middle of the frame), a first wire carrier 412, a first wire pressing mechanism 413, and a first pulling drive mechanism 414. The first wire carrier 412 is disposed on the first pulling base 411. A first wire groove 4121 is formed on the surface of the first wire carrier 412 for inserting the end of the flat wire 90 and extending along the first direction D1. The first wire pressing mechanism 413 is disposed on the first pulling base 411 and is used to press the end of the flat wire 90 against the first wire carrier 412. The first pulling drive mechanism 414 is connected to the first pulling base 411 and is used to move the first pulling base 411 along the first direction D1. The second pulling device 420 includes a second pulling base 421, a second wire carrier 422, a second wire pressing mechanism 423, and a second pulling drive mechanism 424. The second pulling base 421 is arranged side by side and spaced apart from the first pulling base 411 in the first direction D1. The second wire carrier 422 is disposed on the second pulling base 421. The surface of the second wire carrier 422 is formed with a second wire groove 4221 for inserting the end of the flat wire 90 and extending along the first direction D1. The second wire pressing mechanism 423 is disposed on the second pulling base 421 and is used to press the end of the flat wire 90 against the second wire carrier 422. The second pulling drive mechanism 424 is connected to the second pulling base 421 and is used to move the second pulling base 421 along the first direction D1. The second wire pressing mechanism 423 includes a non-metallic contact block 425 for contacting the flat wire 90.

[0025] In this embodiment, the leveling support frame is provided with a first leveling guide rail 43, which extends along the first direction D1. A first traction base 411 is movably mounted on the first leveling guide rail 43. A first wire carrier 412 and a first wire pressing mechanism 413 are respectively supported on the first traction base 411. A first traction drive mechanism 414 is, but is not limited to, a motor screw drive mechanism (i.e., an electric motor). The first traction drive mechanism 414 is supported on the leveling support frame and connected to the first traction base 411. The line leveling device 400 also includes a traction base 44, which is arranged side by side and spaced apart from the first traction base 411 along the first direction D1. A second leveling guide rail 45 extending along the first direction D1 is provided on the traction base 44. A second traction base 421 is movably mounted on the second leveling guide rail 45. A second wire carrier 422 and a second wire pressing mechanism 423 are respectively supported on the second traction base. On seat 421; thus, after the flat wire 90 is moved into the line leveling device 400, one end of the flat wire 90 is placed in the first wire groove 4121 of the first wire carrier 412, and the other end of the flat wire 90 is placed in the second wire groove 4221 of the second wire carrier 422. The first pressing mechanism 413 and the second pressing mechanism 423 are controlled to press the two ends of the flat wire 90 onto the first wire carrier 412 and the second wire carrier 422 respectively. Then, the first pulling drive mechanism 414 and the second pulling drive mechanism 424 move the first pulling base 411 and the second pulling base 421 in opposite directions, thereby flattening the flat wire 90. In this way, since the second pressing mechanism 423 uses a non-metallic contact block 425 to contact the flat wire 90, relative displacement can be generated between the contact block 425 and the flat wire 90 during the flattening process, which can avoid the paint wear of the flat wire 90 during the pulling process, thereby ensuring product quality. It should be noted that during leveling, the first pulling drive mechanism 414 is the main driving source for pulling. That is, after the flat wire 90 is fed into the first pulling device 410 and the second pulling device 420, the first pulling base 411 is approximately located at the right end of the first leveling guide rail 43 (the right end in the figure), and the second pulling base 421 is also located at the right end of the second leveling guide rail 45 (the right end in the figure). After the first pressing mechanism 413, the first wire carrier 412, the second pressing mechanism 423, and the second wire carrier 422 clamp the two ends of the flat wire 90 respectively, the first pulling base 411 moves to the left (the left direction in the figure) under the drive of the first pulling drive mechanism 414, thereby leveling the flat wire 90.

[0026] See Figure 1 , Figure 4 , Figure 5 In this embodiment, the number of first wire slots 4121 on the first wire carrier 412 is multiple, and the multiple first wire slots 4121 are arranged along a second direction perpendicular to the first direction D1; the number of second wire slots 4221 on the second wire carrier 422 is multiple, and the multiple second wire slots 4221 are arranged along the second direction.

[0027] See Figures 1 to 3 The first pressing mechanism 413 provided in this embodiment includes a punch mounting base 4131, a pressing punch 4132 for pressing the end of the flat wire 90 on the first wire carrier 412 against the first wire carrier 412, and a punch driving assembly 4133 for driving the pressing punch 4132 to rise and fall. The punch mounting base 4131 is mounted on the first traction base 411, and the pressing punch 4132 is movably mounted on the punch mounting base 4131 and located above the first wire carrier 412. The punch driving assembly 4133 includes a punch power component 41331 and a punch connecting rod 41332 rotatably mounted on the punch mounting base 4131. One end of the punch connecting rod 41332 is hinged to the pressing punch 4132, and the other end is hinged to the punch power component 41331. The punch power component 41331 is rotatably mounted on the first traction base 411. In this embodiment, the first wire carrier 412 and the punch mounting base 4131 are fixedly mounted on the first traction base 411 by screws, welding or any other existing fixing method. The wire pressing punch 4132 is movably mounted on the punch mounting base 4131 in a direction perpendicular to the surface of the first traction base 411 and is located above the first wire carrier 412. The punch drive assembly 4133 includes a punch power member 41331 and a punch connecting rod 41332. The middle part of the punch connecting rod 41332 is hinged to the top of the punch mounting base 4131. The two ends of the punch connecting rod 41332 are respectively hinged to the top of the punch power member 41331 and the top of the pressing punch 4132. The punch power member 41331 is rotatably mounted on the first traction base 411. The punch power member 41331 is, but is not limited to, a cylinder. It can be understood that the extension and retraction of the output shaft of the punch power member 41331 can drive the punch connecting rod 41332 to swing, causing the pressing punch 4132 to move up and down. In this way, after the end of the flat wire 90 is placed on the first wire carrier table 412, the punch power member 41331 drives the pressing punch 4132 to descend onto the first wire carrier table 412, thereby pressing the flat wire 90 onto the first wire carrier table 412.

[0028] See Figure 3 The punch mounting base 4131 provided in this embodiment has a punch groove 41311 for the wire pressing punch 4132 to slide. Both ends of the wire pressing punch 4132 extend beyond the punch groove 41311. In this embodiment, the punch groove 41311 is located above the first wire carrier 412. The punch groove 41311 extends in a direction perpendicular to the surface of the first tension base 411, and both ends penetrate the surface of the punch mounting base 4131. In this way, by forming the punch groove 41311 on the punch mounting base 4131 to install the wire pressing punch 4132, it can be ensured that the wire pressing punch 4132 moves more smoothly and the wire pressing effect is improved.

[0029] See Figure 3 In this embodiment, the bottom end of the pressing punch 4132 is formed with a plurality of teeth 4132a for contacting the flat wire 90. The plurality of teeth 4132a are arranged along the first direction D1. In this way, by forming a plurality of teeth 4132a on the bottom end of the pressing punch 4132, the flat wire 90 can be prevented from sliding after pressing.

[0030] See Figures 1 to 3 The first traction base 411 provided in this embodiment is provided with an end flattening block 415 for abutting against the end face of the flat wire 90 and a flattening power member 416 that can drive the end flattening block 415 to move along the first direction D1; the punch mounting base 4131 is provided with a flattening groove 41312 for the end flattening block 415 to move. In this embodiment, the flattening power member 416 is, but is not limited to, a cylinder. The flattening power member 416 is fixedly installed on the first traction base 411 and located on the side of the first wire carrier 412 away from the second wire carrier 422. The end flattening block 415 is located between the first wire carrier 412 and the flattening power member 416 and is fixed on the output shaft of the flattening power member 416. The side of the end flattening block 415 facing the first wire carrier 412 has a plane perpendicular to the surface of the first traction base 411. Thus, after the flat wire 90 is inserted, the flattening power member 416 drives the end flattening block 415 to move along the first direction D1. After it abuts against the end of the flat wire 90, it can push the flat wire 90 to a predetermined position. Alternatively, after the ends of multiple flat wires 90 abut against each other, the ends of multiple flat wires 90 can be pushed onto the same plane so that the ends of each flat wire 90 are flush.

[0031] See Figure 1 , Figures 4 to 6The second wire pressing mechanism 423 provided in this embodiment includes a wire pressing seat mounting bracket 4231, a wire pressing seat 4232 for pressing the end of the flat wire 90 on the second wire carrier 422 onto the second wire carrier 422, and a wire pressing seat driving assembly 4233 for driving the wire pressing seat 4232 to move up and down; the wire pressing seat mounting bracket 4231 is mounted on the second tension base 421, the wire pressing seat 4232 is movably mounted on the wire pressing seat mounting bracket 4231, the wire pressing seat driving assembly 4233 is supported on the wire pressing seat mounting bracket 4231 and connected to the wire pressing seat 4232; and a contact block 425 is mounted on the bottom of the wire pressing seat 4232. In this embodiment, the wire clamp mounting bracket 4231 is installed on the second traction base 421 using any existing fixing method such as screws or welding. The wire clamp 4232 is installed on the wire clamp mounting bracket 4231 and corresponds to the position of the second wire carrier 422. The wire clamp driving assembly 4233 is, but is not limited to, an electric cylinder. The wire clamp driving assembly 4233 is supported on the top of the wire clamp mounting bracket 4231 and connected to the wire clamp 4232. The contact block 425 is embedded in the wire clamp 4232 and located on the side of the wire clamp 4232 facing the second wire carrier 422. Thus, by adding a non-metallic contact block to the wire clamp 4232... 425. After the flat wire 90 is placed in, the wire pressing seat drive assembly 4233 drives the wire pressing seat 4232 to descend. The contact block 425 abuts against the flat wire 90 and presses the flat wire 90 onto the second wire carrier 422. The first pulling drive mechanism 414 drives the first pulling base 411 to move away from the second pulling device 420 along the first direction D1 to flatten the flat wire 90. Since the contact block 425 is made of non-metallic material and contacts the surface of the flat wire 90, after the flat wire 90 is flattened, as the first pulling base 411 continues to move, displacement can occur between the contact block 425 and the flat wire 90, thereby preventing damage to the paint of the flat wire 90 and affecting product quality.

[0032] See Figure 1 , Figures 4 to 6The second traction base 421 provided in this embodiment includes a front seat 4211 and a rear seat 4212 arranged side by side and spaced apart in the first direction D1. The front seat 4211 is located on the side of the rear seat 4212 close to the first traction base 411, and the second pressing mechanism 423 is supported on the front seat 4211. The rear seat 4212 is provided with an elastic drive member 426 for providing a pulling force to the front seat 4211 in the first direction D1 away from the direction of the first traction base 411. The elastic drive member 426 is connected to the front seat 4211. The second traction drive mechanism 424 is connected to the rear seat 4212. In this embodiment, the front seat 4211 and the rear seat 4212 are movably mounted on the second leveling guide rail 45 of the pulling base 44 via sliders. Driven by the second pulling drive mechanism 424, the front seat 4211 and the rear seat 4212 can move together along the first direction D1. The front seat 4211 and the rear seat 4212 can move relative to each other. It should be noted that during the stamping process of the flat wire 90, the first pulling base 411 on the first pulling device 410 remains stationary, and the first wire pressing mechanism 413 and the first wire carrier 412 clamp one end of the flat wire 90. With the flat wire 90 bent and deformed at any time, the second pulling drive mechanism 424 drives the second pulling base 421 to move at a set speed. That is, while the flat wire 90 bends and shrinks, the second pulling base 421 of the second pulling device 420 clamps the other end of the flat wire 90 and moves it toward the first pulling device 410 to realize the wire feeding action. At the same time, the elastic drive member 426 on the rear seat 4212 provides a pulling force to the front seat 4211 in a direction away from the first pulling base 411. In this way, the flat wire 90 can always be kept taut during the forming process, thereby improving the forming effect.

[0033] See Figure 1 , Figures 4 to 6 In this embodiment, the elastic drive member 426 is a compensation cylinder, which is mounted on the rear seat 4212 and the output shaft of the compensation cylinder is fixed to the front seat 4211.
