Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to an intelligent stamping device for new energy vehicle sheet metal that is easy to demold. Background Technology

Sheet metal processing is frequently used in the processing of vehicle body parts, including those for new energy vehicles.

[0003] When new energy vehicle parts are processed by stamping sheet metal, the material is a thin metal sheet. Simply demolding the formed parts by ejector pins can easily cause the parts to deviate from their position, making it difficult for the robot to grasp them later. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1-6 This utility model provides a technical solution: an easy-to-demold intelligent stamping device for sheet metal in new energy vehicles, comprising:

[0035] The upper template 1 has several punches 11 on it;

[0036] The lower mold mechanism includes a lower mold plate 2 and an ejector plate 3. The lower mold plate 2 is provided with a forming cavity 21, and the stamping plate 9 is placed in the forming cavity 21. The ejector plate 3 is provided with a plurality of first ejector pins 31, which pass through the lower mold plate 2.

[0037] The top material block 4 is disposed on the side wall of the forming cavity 21;

[0038] The upper template 1 is provided with a protruding plate 12 whose shape matches the forming cavity 21. The punch 11 is provided on the protruding plate 12. The bottom surface of the forming cavity 21 is provided with a blanking hole 211 corresponding to the punch 11. The top material block 4 is provided with a connecting rod 41, which is connected to the ejector plate 3. The top material block 4 is provided with a stepped surface, and the stepped surface on the top material block 4 forms a support part 42 extending to the bottom of the plate to be stamped 9.

[0039] The top material block 4 has a cylindrical structure, which makes it easy to install the top material block 4 into the mounting groove on the lower template 2.

[0040] The ejector block 4 is embedded on the lower mold plate 2, and the top of the ejector block 4 does not extend beyond the surface of the lower mold plate 2 to avoid affecting mold closing.

[0041] Working principle: When the stamping device is working, the stamping plate 9 is placed in the forming cavity 21, which fully positions the stamping plate 9 to ensure the forming quality. When the upper mold plate 1 and the lower mold plate 2 are closed, the stamping plate 9 is extruded and formed by the forming cavity 21 and the protrusion plate 12, and the through hole is punched by the punch 11, and the waste material falls into the blanking hole 211. When the forming is completed and the mold is separated, the upper mold plate 1 moves upward and separates from the lower mold plate 2. The ejector plate 3 drives the first ejector pin 31 and the connecting rod 41 to move upward. The part formed by the stamping plate 9 is lifted by the first ejector pin 31. At the same time, the side edge of the part is positioned by the ejector block 4 through the stepped surface and lifted by the support part 42, which fully ensures the demolding effect and prevents the part from shifting position during the demolding process, making it convenient for the robot to pick up the material later.

[0042] Example 2

[0043] Based on the above embodiments, this embodiment further improves upon the following technical solution: the connecting rod 41 is rotatably mounted on the ejector plate 3.

[0044] After the top material block 4 rotates 180 degrees, the step surface and the forming cavity 21 are arranged opposite to each other. The arc-shaped side wall on the back of the top material block 4 extends into the forming cavity 21. When there is an error in the processing of the plate to be stamped 9, the forming cavity 21 can position the plate to be stamped 9 of different widths.

[0045] Example 3

[0046] Based on the above embodiments, this embodiment further improves upon the following technical solution: a driven gear 411 is provided on the connecting rod 41, the motor 5 is fixedly mounted on the ejector plate 3, and the output shaft of the motor 5 is connected to the driving gear 51. The driving gear 51 meshes with the driven gear 411 to achieve precise control of the rotation angle of the ejector block 4.

[0047] Specifically, motor 5 is a servo motor, which further enables precise control of the rotation angle of the top material block 4.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
