Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flat wire motor manufacturing, and in particular to a multi-station die automatic conversion device and conversion method for flat wire forming. BACKGROUND

[0002] In the production and manufacturing process of flat wire motors, flat wire forming is an essential process, which generally includes two key stages: first, the flat wire is processed into a two-dimensional U-shaped wire (i.e., 2D forming), and then the U-shaped wire is further bent into a three-dimensional hairpin coil with a specific spatial angle and shape (i.e., 3D forming), and finally these formed coils are inserted into the motor stator slots in sequence to complete assembly.

[0003] A single stator often needs to integrate coils of multiple different three-dimensional shapes, so multiple flat wire forming dies corresponding to the coils must be provided in production. The traditional production mode usually adopts multiple independent forming devices, each device is installed with a fixed special die, and each device only has the ability to produce a specific shape coil. This method can achieve continuous production, but requires multiple devices, occupying a large amount of factory space. In addition, some existing production modes choose to replace the die manually on a single device. When the coil type needs to be switched, the operator needs to stop the machine, disassemble the original die, install the new die and debug and calibrate. This process not only depends on skilled workers, but also takes a long time to replace the die, during which the device is completely stopped, reducing production efficiency.

[0044] When using, first push table 200 and second push table 300 are placed with several flat wire forming dies, first push table 200 is provided with processing station 210 and first movable position 220, at least one first transition position 230 is arranged between processing station 210 and first movable position 220, first push block 400 can slide along first push table 200, to move the flat wire forming die located on first push table 200, so that it realizes position switching between processing station 210, first transition position 230 and first movable position 220.Similarly, second push table 300 is provided with second transition position 310 and second movable position 320, second transition position 310 and second movable position 320 are arranged in straight line, and second push block 500 can slide along second push table 300, to move the flat wire forming die located on second push table 300, so that it realizes position switching between second transition position 310 and second movable position 320.

[0045] As Figure 2As shown, the first movable position 220 and the second movable position 320 are connected and can be synchronously slid along the first slide rail 110. When the flat wire forming die is located on the first movable position 220, the first movable position 220 and the second movable position 320 are synchronously slid along the first slide rail 110, and the first movable position 220 can be slid to be flush with the second transition position 310. At this time, the flat wire forming die on the first movable position 220 is moved to the second transition position 310 by the second push block 500.

At this time, the flat wire forming die on the second movable position 320 is moved to the first transition position 230 by the first push block 400. In this way, the position switching of the flat wire forming die between the first push table 200 and the second push table 300 is realized, the target flat wire forming die is moved to the processing station 210, the flat wire pressing forming is completed, and the purpose of automatic die changing is achieved.

[0046] In the embodiment, a plurality of flat wire forming dies are arranged on the first push table 200 and the second push table 300. The flat wire forming dies are dies of different shapes to press the flat wire into coils of different three-dimensional shapes. In actual application, the switching sequence of the flat wire forming dies can be preset in advance to ensure that the flat wire pressed after each die change is of a target shape. The preset program is prior art and will not be described herein.

[0047] In an embodiment, the pressing die assembly 600 is arranged directly above the processing station 210. The pressing die assembly 600 includes a pressing die and a motor. The motor is in transmission connection with the pressing die. The pressing die is driven to move along the y-axis direction by the motor to extrude the flat wire forming die located on the processing station 210 to press the flat wire into a shape.

[0048] As shown in the embodiment, the number of the first transition position 230 and the second transition position 310 is greater than the number of the flat wire forming dies. Figure 1 In the embodiment, the number of the first transition position 230 and the second transition position 310 is greater than the number of the flat wire forming dies. In use, the first transition position 230 is arranged between the first movable position 220 and the processing station 210 and is provided with at least one. The second transition position 310 is provided with at least two. The second movable position 320 is arranged in a straight line with the second transition position 310 and is located between the second transition position 310. That is, the second movable position 320 is provided with the second transition position 310 on both sides. In this way, the second push block 500 can move the flat wire forming die located on the second movable position 320 to both sides of the second movable position 320, and the flexibility of the flat wire forming die position switching is increased.

[0049] Specifically, the number of the first transition positions 230 is greater than the number of the flat wire forming dies, and the number of the second transition positions 310 is also greater than the number of the flat wire forming dies, so that when the flat wire forming dies are placed on the first push table 200 and the second push table 300, there are idle positions on the first push table 200 and the second push table 300 in addition to the processing stations 210, the first movable positions 220 and the second movable positions 320, so as to realize the position change of the flat wire forming dies.

[0050] In an embodiment, the first push table 200 is provided with two first transition positions 230 and two first movable positions 220; the two first transition positions 230 are arranged at intervals, and a processing station 210 is formed between the two first transition positions 230; the two first movable positions 220 are arranged on the sides of the two first transition positions 230 away from the processing station 210, that is, one first movable position 220 is arranged at each end of the first push table 200; the second push table 300 is provided with six second transition positions 310 and two second movable positions 320; the two second movable positions 320 are arranged at intervals, and are located between the six second transition positions 310; among them, the two second movable positions 320 are arranged in a straight line with the two first movable positions 220; meanwhile, three second transition positions 310 are arranged between the two second movable positions 320; in addition, one second transition position 310 is arranged at one end of the second push table 300, and two second transition positions 310 are arranged at the other end. That is, one first transition position 230 and two second transition positions 310 are arranged at one end of the rack 100, so as to realize the position change of three flat wire forming dies; one first transition position 230 and four second transition positions 310 are arranged at the other end of the rack 100, so as to realize the position change of five flat wire forming dies.

[0051] In the embodiment, the first slide rails 110 are also two, which are arranged in parallel on the rack 100 along the x-axis direction and are located at the two ends of the rack 100, so that the first movable positions 220 and the second movable positions 320 located at the two ends of the rack 100 can slide along the first slide rails 110.

[0052] As shown in FIGS. 1, 2 and 3, in the embodiment, the first movable positions 220 and the second movable positions 320 are arranged at the two ends of the first push table 200 and the second push table 300, respectively.

Specifically, in actual use, the first drive member 111 is arranged at the end of the first slide rail 110, and the output shaft of the first drive member 111 is in transmission connection with the first movable position 220 and the second movable position 320, so that the first drive member 111 drives the first movable position 220 and the second movable position 320 to move synchronously along the first slide rail 110.

[0053] In the initial state, the first movable position 220 and the first transition position 230 are flush, and the second movable position 320 and the second transition position 310 are flush. At the same time, the first movable position 220 and the second movable position 320 are connected to each other and arranged in a straight line. When the first driving member 111 is started, the first movable position 220 and the second movable position 320 move synchronously. The first movable position 220 can slide to be flush with the second transition position 310. At this time, the second movable position 320 is not in the same straight line with the first transition position 230 and the second transition position 310, but the second movable position 320 is parallel to the first transition position 230 and the second transition position 310. In another case, the second movable position 320 can slide to be flush with the first transition position 230. At this time, the first movable position 220 is not in the same straight line with the first transition position 230 and the second transition position 310, but the first movable position 220 is parallel to the first transition position 230 and the second transition position 310.

The end of the first push block 400 away from the first connecting block 250 extends towards the first push table 200. The length of the first connecting block 250 is greater than or equal to three times the length of the flat wire forming die.

[0056] Specifically, the top of the rack 100 is provided with a second slide rail 240, which is parallel to the first push table 200. One end of the first connecting block 250 is slidably arranged on the second slide rail 240, and the other end extends towards the first push table 200 to push the flat wire forming die located on the first push table 200 to switch positions between the processing station 210, the first transition position 230 and the first movable position 220.

[0058] In the present embodiment, as shown in Figure 1 The multi-station die automatic conversion equipment for flat wire forming further comprises a third sliding rail 330 and a second connecting block 340; the third sliding rail 330 is arranged on the top of the rack 100 in the z direction and above the second pushing table 300; the second connecting block 340 is slidably arranged on the third sliding rail 330; both ends of the second connecting block 340 are provided with a second pushing block 500; and the end of the second pushing block 500 away from the second connecting block 340 extends towards the second pushing table 300.

[0061] In an embodiment, the second pushing table 300 is provided with six second transition positions 310, and at this time, the length of the second connecting block 340 is five times the length of the flat wire forming die, so that when the two second pushing blocks 500 are arranged at both ends of the second connecting block 340 at the same time, five flat wire forming dies can be moved synchronously, improving the displacement efficiency and ensuring that the displacement sequence of the flat wire forming die is not disturbed.

[0062] AsFigure 1 and Figure 4 As shown, in this embodiment, the frame 100 is provided with a second driving member 410 and a third driving member 510.

The cross-sectional shape of the first limiting platform 700 is an inverted "L" shape; and / or, the cross-sectional shape of the second limiting platform 800 is an inverted "L" shape.

[0065] Specifically, in actual use, the first limiting platform 700 has an inverted "L" shaped cross-section and is located at the edge of the first push platform 200. When a flat wire forming mold is placed on the first push platform 200, the first limiting platform 700 engages with the mold to prevent it from shifting and falling off during movement.
