Description

Technical Field

[0001] The present application relates to the technical field of cover plate stamping, and in particular to a stamping machine for a motor controller cover plate. Background Art

[0002] As an important component in modern industry, motor controllers are widely used in the drive and control of various mechanical equipment. Among them, the cover plate, as a key component of the motor controller, not only protects the internal components, but also affects the heat dissipation performance and appearance of the controller. And the motor controller cover plate is one of the few thin-walled flat parts in the electric drive system. It is generally arranged at the highest plane of the electric drive, and the noise can easily be transmitted to the interior of the vehicle through the upper cover plate. The motor controller cover plate is generally a cast aluminum alloy part, so that the cover plate can prevent the internal noise of the controller from being transmitted to the outside of the controller.

[0003] The existing Chinese public patent authorization announcement number: CN219541478U mentions a power cover stamping die, including an upper die assembly, a lower die assembly, a plurality of punching punches, a bending assembly, a letter pressing piece and a trimming punch; the upper die assembly is connected to a punching machine; the lower die assembly is arranged relative to the upper die assembly up and down, and is connected to the punching machine; the plurality of punching punches are arranged on the upper die assembly for punching holes in the material; the bending assembly is arranged on the upper die assembly and the lower die assembly for bending the material; the letter pressing piece is arranged at the bottom of the upper die assembly for pressing letters on the material; the trimming punch is arranged on the upper die assembly for cutting the material so as to separate the processed area on the material from the material. The power cover stamping die provided by the utility model has a compact structure, can process the material in a variety of processes, and thus process the desired product, which can not only greatly reduce the processing cost, but also improve the processing efficiency, and is convenient for use.

[0004] However, the prior art utilizes a material conveying mechanism to convey the material between the upper die assembly and the lower die assembly during use, and then drives the upper die assembly to move downward through the punching machine. During the downward movement of the lower die assembly, the material is pressed downward until the material is pressed onto the lower die assembly, thereby completing the clamping of the upper die assembly and the lower die assembly. During the clamping process, there is a lack of a process for positioning and aligning the material, which can easily cause deviations in the material when being stamped by the upper die assembly, thereby affecting the stamping accuracy of the device. Utility Model Content

[0042] When in use, the debris generated by the stamping of the cover body 10 on the top of the lower template 6 is guided and collected by setting a guiding slope 23, so that the debris slides to the inner bottom of the debris collection groove 15 under the action of gravity, and at the same time, while driving the downward push plate 4 to move along the length direction of the guide slide groove 11, the downward push plate 4 drives the transmission rack 1 20 to engage with the transmission gear 21, and the transmission gear 21 is meshed with the transmission rack 22, and at the same time, the transmission rack 22 pushes the push plate 19 to move back and forth along the length direction of the push slide groove 18, so that the push plate 19 pushes the debris collected in the debris collection groove 15 through the discharge port 16 and falls into the waste box 17, thereby facilitating the automatic collection of the debris generated by the stamping of the cover body 10 and improving the practicability of the device.

[0043] The implementation principle of a punching machine for a motor controller cover in this embodiment is as follows: first, the cover body 10 is placed on the top of the lower template 6, and then the hydraulic cylinder 3 is started to push the lower push plate 4 and the upper template 5 downward along the length direction of the guide slide groove 11, and at the same time, the lower push plate 4 drives the inclined push plate 9 to form a conflict with the positioning clamping plate 8 along the length direction of the guide slide groove 11, and pushes the positioning clamping plate 8 to squeeze the rebound spring 14 along the length direction of the rebound slide rod 13, so that the rebound spring 14 produces a contraction deformation, and at the same time, the inclined push plate 9 pushes the two positioning clamping plates 8 to move closer to each other along the length direction of the rebound slide rod 13, and the two positioning clamping plates 8 form a center clamping positioning for the cover body 10, and then the lower push plate 4 drives the upper template 5 to squeeze the cover body 10 and the surface of the lower template 6, and at the same time squeezes the elastic ejection block 24, so as to form a positioning stamping for the cover body 10;
