Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a stamping and forming device for flat wires. Background Art

[0002] At present, a motor with a stator winding using a rectangular cross-section wire is called a flat wire motor (also called a Pin motor). Different from a common wound motor, the flat wire motor does not first wind a round wire into a specific coil and then embed it into the stator slot by a machine. Instead, the flat wire (also called copper wire or flat copper wire, hereinafter collectively referred to as flat wire for the sake of unified technical terms) is preformed, inserted into the stator slot, and then formed and welded again at one or both ends to form the entire stator winding. The flat wire is beneficial to improving the slot filling factor of the motor. Generally, the slot filling factor of a round wire motor is about 50%, while that of a flat wire motor can reach more than 70%. According to the winding form of the flat wire motor, it can be further divided into Hair-pin winding (also called hairpin winding), I-Pin winding (also called I-type clip winding), wave winding, etc. The hairpin-type flat wire winding gets its name because its shape is more like a hairpin. Its advantage is that only one end needs to be welded, and its disadvantage is that the preparation is relatively complex. After the hairpin is formed, the hairpin wires are inserted into the stator core in groups, and finally assembled into a finished motor stator through equipment such as flaring, twisting, welding, and dipping. The process of the hairpin forming machine mainly includes unwinding, removing the paint film, cutting to a fixed length, and forming. The existing stamping equipment is large in volume, complex in structure, and expensive in price. The molds are all locked under the equipment, and the replacement is very inconvenient, time-consuming, and laborious. Content of the Utility Model

[0027] The above-mentioned stamping and forming device 100 for flat wires includes a support device 10 and a pressing device 20. The support device 10 includes a carrier table 11 for placing the lower die part 91 and a translation driving mechanism 12, and the pressing device 20 includes a lifting table 22 for fixing the upper die part 92 and a lifting driving mechanism 23 for driving the lifting table 22 to move towards the carrier table 11 to close the upper die part 92 and the lower die part 91. A first positioning component 30 is provided on the carrier table 11 for positioning the lower template 911 of the lower die part 91 and holding the lower template 911 on the carrier table 11, and a second positioning component 40 is provided on the lifting table 22 for positioning the upper template 921 of the upper die part 92 and holding the upper template 921 on the lifting table 22. In this way, the convenience of die replacement can be improved and the die change time is reduced.

[0028] See Figures 1 to 4 Referring to

[0029] See Figures 1 to 4, the supporting device 10 provided in this embodiment is used to support the lower die part 91. The supporting device 10 includes a bearing table 11 and a translation driving mechanism 12. The bearing table 11 is used to place the lower die part 91. The loading and unloading station 1a and the stamping station 1b are arranged side by side along the first direction D1. The bearing table 11 can reciprocate between the loading and unloading station 1a and the stamping station 1b. The translation driving mechanism 12 can drive the bearing table 11 to move along the first direction D1 to move into and out of the pressing device 20. A first positioning component 30 is arranged on the bearing table 11, which is used to position the lower template 911 of the lower die part 91 and hold the lower template 911 on the bearing table 11. In this embodiment, the first positioning component 30 includes a first longitudinal stop bar 31 and two transverse stop bars 32. The first longitudinal stop bar 31 and the transverse stop bars 32 are both fixedly installed on the bearing table 11 by all existing fixing methods such as screws and welding. The two transverse stop bars 32 extend along the first direction D1 respectively and are spaced in the second direction D2. The first longitudinal stop bar 31 extends along the second direction D2 and is located between the two transverse stop bars 32. The first longitudinal stop bar 31 and the two transverse stop bars 32 enclose a first installation space 30a for the lower template 911 to be placed in. The length dimension of the transverse stop bar 32 is greater than the length dimension of the lower template 911, and the distance between the two transverse stop bars 32 is basically equal to the width dimension of the lower template 911. The first positioning component 30 further includes an extrusion component 33 for pressing the lower template 911 against the first longitudinal stop bar 31. It is worth mentioning that when the first longitudinal stop bar 31 and the transverse stop bars 32 are installed on the bearing table 11 by using fasteners such as screws, according to different die sizes, the positions of the first longitudinal stop bar 31 and the transverse stop bars 32 on the bearing table 11 can be adjusted to adapt.

[0030] Specifically, the extrusion component 33 includes a fixed block 331 fixed on the bearing table 11 and an extrusion bolt 332 whose axis extends along the first direction D1. The extrusion bolt 332 is threadedly connected to the fixed block 331. The fixed block 331 is fixedly installed on the bearing table 11 by all existing fixing methods such as screws and welding and is located between the two transverse stop bars 32. In this way, after the lower template 911 of the lower die part 91 is placed in the first installation space 30a, the lower template 911 can be limited in the second direction D2 by the contact between the two transverse stop bars 32 and the lower template 911. By turning the extrusion bolt 332, one end of the extrusion bolt 332 is driven to move towards the first longitudinal stop bar 31, so as to limit the lower template 911 in the first direction D1, thereby holding the lower die part 91 on the bearing table 11.

[0031] In other embodiments, a groove can be formed on the bearing table 11. The shape of the groove is adapted to the shape of the lower template 911 and extends to the periphery of the bearing table 11. The above-mentioned extrusion component 33 is arranged on the bottom surface of the groove of the bearing table 11.

[0032] In yet another embodiment, the extrusion member 33 may be driven by a cylinder.

[0033] Refer to Figures 1 to 4 , in this embodiment, the support device 10 further includes two slide rails 13 extending along the first direction D1. The two slide rails 13 are spaced apart in the second direction D2. The carrier table 11 is slidably disposed on the two slide rails 13 through sliders. In this way, the carrier table 11 can be supported and guided to move by the slide rails 13.

[0034] Refer to Figures 1 to 4 , in this embodiment, the translation drive mechanism 12 includes a lead screw 121, a nut seat 122 mounted on the lead screw 121, a motor 123 capable of rotating the lead screw 121, and a transmission assembly 124 connecting the motor 123 and the lead screw 121. The nut seat 122 is fixedly connected to the carrier table 11. The lead screw 121 is disposed between the two slides. The transmission assembly 124 may be a synchronous pulley and synchronous belt transmission assembly 124. In this way, the positioning accuracy of the carrier table 11 is high and the transmission efficiency is high.

[0035] Refer to Figures 1 to 4, the pressing device 20 provided in this embodiment is used to support the upper die part 92. The pressing device 20 includes a support frame 21, a lifting table 22, and a lifting drive mechanism 23. The support frame 21 is arranged on the stamping station 1b. The lifting table 22 is used to fix the upper die part 92. The lifting table 22 is installed on the support frame 21 in a liftable manner and is located above the carrier table 11. The lifting drive mechanism 23 is used to drive the lifting table 22 to move towards the carrier table 11 to close the upper die part 92 and the lower die part 91; a second positioning component 40 is arranged on the lifting table 22, which is used to position the upper template 921 of the upper die part 92 and hold the upper template 921 on the lifting table 22. In this embodiment, the second positioning component 40 includes a second longitudinal stop bar 41 and two transverse stoppers 42. The second longitudinal stop bar 41 and the transverse stoppers 42 are both fixedly installed on the lifting table 22 by all existing fixing methods such as screws and welding. The two transverse stoppers 42 respectively extend along the first direction D1 and are spaced in the second direction D2. The second longitudinal stop bar 41 extends along the second direction D2 and is located between the two transverse stoppers 42. The second longitudinal stop bar 41 and the two transverse stoppers 42 enclose a second installation space 40a for the upper template 921 to be placed; the length dimension of the transverse stopper 42 is greater than the length dimension of the upper template 921, and the distance between the two transverse stoppers 42 is basically equal to the width dimension of the upper template 921. The transverse stopper 42 includes a vertical portion 421 connected to the lifting table 22 and a horizontal portion 422 extending from the vertical portion 421 into the interior of the second installation space 40a. The horizontal portion 422 abuts against the surface of the upper template 921 on the side where the upper die core is installed; the second positioning component 40 further includes a pressing component 43 for cooperating with the second longitudinal stop bar 41 to limit the movement of the upper template 921 in the first direction D1. It is worth mentioning that when the second longitudinal stop bar 41 and the transverse stoppers 42 are installed on the lifting table 22 by fasteners such as screws, according to different die sizes, the positions of the second longitudinal stop bar 41 and the transverse stoppers 42 on the lifting table 22 can be adjusted to adapt.

[0036] Specifically, the lifting table 22 has an assembly groove 221 communicating with the second installation space 40a. The pressing member 43 is built in the assembly groove 221. A pressing driving member 44 for driving the pressing member 43 to extend into the second installation space 40a and abut against the periphery of the upper template 921 is provided on the lifting table 22. The pressing driving member 44 is, but not limited to, a cylinder. In this way, after the upper template 921 of the upper die part 92 is placed in the second installation space 40a, the vertical part 421 of the two transverse stoppers 42 contacts the upper template 921 to limit the upper template 921 in the second direction D2. The horizontal part 422 can hold the upper template 921 on the lifting table 22 in the up and down direction. After the pressing driving member 44 drives the pressing member 43 to extend downward into the second installation space 40a and abut against the periphery of the upper template 921, the pressing member 43 and the second longitudinal bar 41 limit the upper template 921 in the first direction D1.

[0037] In other embodiments, a groove may be formed on the lifting table 22. The shape of the groove is adapted to the shape of the upper template 921 and extends to the periphery of the lifting table 22. The pressing member 43 described above is provided on the bottom surface of the groove of the lifting table 22.

[0038] See Figures 1 to 4 , the pressing member 43 provided in this embodiment has a pressing inclined surface (not shown in the figure) for contacting the upper template 921. The pressing inclined surface extends downward and away from the second longitudinal bar 41 from the side of the pressing member 43 facing the second longitudinal bar 41. In this way, by providing the pressing inclined surface, the upper template 921 can be pushed to move when the pressing member 43 moves downward, and the upper template 921 can be pressed against the second longitudinal bar 41.

[0039] See Figure 1 and Figure 4 , the pressing device 20 provided in this embodiment further includes a pre-positioning assembly 50 provided below the lifting table 22. The pre-positioning assembly 50 includes a pre-positioning block 51 and a pre-positioning driving member 52 for driving the pre-positioning block 51 to move; a pre-positioning notch 11a for the pre-positioning block 51 to move into is formed on the periphery of the carrier table 11. The pre-positioning block 51 can move along the second direction D2 under the drive of the pre-positioning driving member 52. After the carrier table 11 moves to the stamping station 1b, the pre-positioning block 51 extends out under the control of the pre-positioning driving member 52 and cooperates with the pre-positioning notch 11a on the carrier table 11 for positioning, so as to position the position of the carrier table 11, and then control the lifting table 22 of the pressing device 20 to move downward for mold closing.

[0040] In other embodiments, the position of the carrier table 11 can also be positioned by a position sensor.

[0041] See Figure 1 and Figure 4, in this embodiment, the shape of the pre-positioning notch 11a is triangular, and the pre-positioning block 51 has a longitudinal section whose shape matches that of the pre-positioning notch 11a.

[0042] In other embodiments, the shape of the pre-positioning notch 11a is semi-circular or oval.

[0043] See Figure 1 and Figure 4 , in the lifting platform 22 provided in this embodiment, there are guide columns 24 extending in the up and down directions. The lifting platform 22 is connected to the support frame 21 through the guide columns 24. The number of the guide columns 24 is four but not limited to four, and they are respectively located at the four corners of the lifting platform 22. The lifting drive mechanism 23 includes an electric cylinder supported on the support frame 21, and the output shaft of the electric cylinder is fixedly connected to the lifting platform 22.

[0044] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
