Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die for processing new energy vehicle parts. Background Technology

[0002] Many of the components in the drive motors used in the production of new energy vehicles are formed by stamping using stamping dies.

[0003] A stamping die for non-oriented silicon steel sheets used in drive motors of new energy vehicles, disclosed in Chinese patent CN219703211U, features a limiting component in the middle. When the non-oriented silicon steel sheet to be used in the drive motor is placed into the die cavity, the upper module slides downwards to perform the stamping operation. The upper module is surrounded by limiting components; as it slides downwards, the limiting posts slide into the center of the limiting holes for restraint, increasing the stamping effect and accuracy. However, while solving this problem, this stamping die for non-oriented silicon steel sheets used in drive motors of new energy vehicles has the following drawbacks:

[0004] During material handling, the lower module moves to the bottom of the fan box. After material handling is completed, the non-oriented silicon steel sheet needs to be placed back into the mold cavity of the lower module. Then the lower module is pushed under the upper module before it can be stamped again. The material handling process needs to be completed in this process, resulting in low overall stamping efficiency. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose a stamping die for processing new energy vehicle parts, which aims to solve the problem of low overall stamping efficiency of existing stamping dies for non-oriented silicon steel sheets used in new energy vehicle drive motors.

[0007] To achieve the above objectives, one embodiment of this utility model provides a stamping die for processing new energy vehicle parts, including a base and a stamping plate. The stamping plate is located above the base, and a flange is fixedly connected to the top of the stamping plate. An upper module is fixedly installed below the stamping plate. Two lower modules are slidably connected to the top of the base. Symmetrical bearing seats are provided on both sides of the top of the base, and a lead screw is rotatably connected inside the bearing seats. Traction blocks are provided on both sides of the lower modules, and the traction blocks are threaded to the outer surface of the lead screw. A second bearing seat is provided on one side of the top of the base, and a transmission shaft is rotatably connected inside the bearing seat. A motor is installed on one side of the base, and the output shaft end of the motor is connected to the transmission shaft through a coupling. Two bevel gears are fixedly connected to the outer surface of the transmission shaft, and bevel gears meshing with the bevel gears are fixedly connected to the ends of the two lead screws.

[0008] The beneficial effects are as follows: the lead screw, bevel gear, drive shaft and motor structure can drive the two lower modules to move synchronously. So when one lower module moves to the bottom of the upper module, the other lower module moves to the side of the stamping plate. Thus, when the upper module under the stamping plate is stamping the non-oriented silicon steel sheet in one of the lower modules, it can perform the material handling operation on the other lower module. Therefore, the material handling operation will not affect the stamping of the upper module, thus having the advantage of high-efficiency stamping.

[0009] Furthermore, guide rods are fixedly connected to both sides of the top of the base, and guide holes corresponding to the guide rods are opened on the stamping plate. The stamping plate is slidably sleeved on the outer surface of the guide rods through the guide holes to guide the stamping plate.

[0010] Furthermore, the bottom of the stamping plate is provided with a positioning groove, the upper module is inserted into the inside of the positioning groove, and the inside of the positioning groove is provided with multiple insertion holes. The top of the upper module is fixedly connected with multiple screws corresponding to the insertion holes. The screws are inserted into the inside of the insertion holes, and the outer surface of the screws is threaded with nuts for fixing the upper module under the stamping plate, so that the upper module can be disassembled.

[0011] In a preferred embodiment, the lower module has longitudinal connecting grooves on both sides, and the connecting grooves extend to the bottom of the lower module. A connecting block is fixedly connected to one side of the traction block, and the connecting block slides from the bottom of the lower module into the connecting groove, which facilitates the assembly and disassembly of the lower module.

[0012] Furthermore, chamfers are provided on both sides of the bottom end of the connecting groove to facilitate the insertion of the connecting block into the connecting groove.

[0013] Furthermore, guide rails are fixedly installed on both sides of the top of the base, and a guide rail groove is opened at the bottom of the traction block. The traction block is slidably connected to the outer surface of the guide rail through the guide rail groove, so as to avoid the problem that the traction block rotates synchronously when the lead screw rotates, which would lead to inaccurate traction distance to the lower module.

[0014] The beneficial effects are as follows: When installing the lower module, the lower module is lifted using hoisting equipment and placed on top of the base, with the connecting slots on both sides of the lower module interlocking with the surface of the connecting block. When disassembling, the lower module can be lifted directly upwards, which facilitates the disassembly and assembly of the lower module and makes it easy to replace lower modules of different sizes.

[0015] Furthermore, a slider is fixedly connected to the bottom of the lower module, and a groove corresponding to the slider is opened on the top of the base. The slider is slidably connected inside the groove to guide the sliding direction of the lower module.

[0016] In a preferred embodiment, the lower module has a mold cavity at its top and multiple mounting slots at its bottom. A nitrogen spring is fixedly installed inside the mounting slots, and a top plate is installed at the top of the nitrogen spring piston rod. After stamping, the nitrogen spring rebounds, and the stamped material can be pushed out of the mold cavity through the top plate, thus facilitating material removal.

[0029] This utility model provides a stamping die for processing new energy vehicle parts.

[0030] Example 1:

[0031] like Figure 1 As shown, it includes a base 1 and a stamping plate 2. The stamping plate 2 is located above the base 1, and a flange 21 is fixedly connected to the top of the stamping plate 2 for connecting with the hydraulic cylinder inside the stamping equipment.

[0032] like Figure 1 , Figure 3 and Figure 4As shown, a positioning groove 23 is provided at the bottom of the stamping plate 2, and multiple insertion holes 24 are provided inside the positioning groove 23. An upper module 3 is inserted into the positioning groove 23, and multiple screws 31 corresponding to the insertion holes 24 are fixedly connected to the top of the upper module 3. The screws 31 are inserted into the insertion holes 24, and nuts 32 are threaded on the outer surface of the screws 31 to fix the upper module 3 under the stamping plate 2.

[0033] like Figure 1 As shown, two lower modules 4 are slidably connected to the top of the base 1. Symmetrical bearing seats 12 are provided on both sides of the top of the base 1, and a lead screw 13 is rotatably connected inside the bearing seat 12. Traction blocks 5 are provided on both sides of the lower modules 4, and the traction blocks 5 are threaded to the outer surface of the lead screw 13. Rotating the lead screw 13 can drive the two lower modules 4 to move. A bearing seat 14 is provided on one side of the top of the base 1. A transmission shaft 15 is rotatably connected inside the bearing seat 14. A motor 16 is installed on one side of the base 1. The output shaft end of the motor 16 is connected to the transmission shaft 15 through a coupling. Two bevel gears 17 are fixedly connected to the outer surface of the transmission shaft 15. The ends of the two lead screws 13 are fixedly connected to bevel gears 18 that mesh with the bevel gears 17, so that the motor 16 can drive the lead screws 13 to rotate.

[0034] Furthermore, such as Figure 2 and Figure 5 As shown, a slider 41 is fixedly connected to the bottom of the lower module 4, and a groove 19 corresponding to the slider 41 is opened on the top of the base 1. The slider 41 is slidably connected inside the groove 19 to guide the sliding direction of the lower module 4.

[0035] Furthermore, such as Figure 2 and Figure 5 As shown, the top of the lower module 4 is provided with a mold cavity 42, and the bottom of the mold cavity 42 is provided with multiple mounting slots 43. A nitrogen spring 44 is fixedly installed inside the mounting slot 43. A top plate 45 is installed at the top of the piston rod of the nitrogen spring 44.

[0038] Furthermore, guide rails 110 are fixedly installed on both sides of the top of the base 1, and guide rail grooves 52 are opened at the bottom of the traction block 5. The traction block 5 is slidably connected to the outer surface of the guide rail 110 through the guide rail grooves 52, so as to avoid the problem that the traction block 5 rotates synchronously when the lead screw 13 rotates, which would lead to inaccurate traction distance to the lower module 4.

[0039] The working principle of this utility model is as follows: The base 1 is fixed below the stamping equipment, and the stamping plate 2 is connected to the hydraulic cylinder of the stamping equipment through the top flange 21. In use, the non-oriented silicon steel sheet to be used in the new energy vehicle drive motor is first placed in the middle of the mold cavity 42. Then, the motor 16 drives the lead screw 13 to rotate, driving the two lower modules 4 to move synchronously, so that the lower module 4 containing the non-oriented silicon steel sheet moves to the lower module 3. At this time, the hydraulic cylinder of the stamping equipment drives the stamping plate 2 to descend, and the upper module 3 presses against the non-oriented silicon steel sheet in the lower module 4. The sheet is stamped. During the stamping process, those skilled in the art can place the non-oriented silicon steel sheet in the mold cavity of another lower module 4. After the stamping is completed, the motor 16 drives the two lower modules 4 to move again, moving the stamped material to one side of the stamping plate 2. The other lower module 4 containing the non-oriented silicon steel sheet moves to the bottom of the stamping plate 2. During the removal of the stamped material and the process of feeding the material again, the upper module 3 under the stamping plate 2 simultaneously performs a new round of stamping work, thus achieving the advantage of high stamping efficiency.
