[0023] like Figure 1-4 As shown, a large-size flange plate edge waste punching mechanism is installed on a stamping die, and the stamping die includes a matching upper die 10 and a lower die 20; wherein:

[0024] An upper mold plate 11 is provided at the lower end of the upper mold 10. A groove 1 adapted to the flange plate 30 is formed at the lower end of the upper mold plate 11. A guide hole groove 2 is provided on the outer periphery of the groove 1 on the upper mold plate 11.

[0025] The lower mold 20 includes a support seat 21 and a lower mold plate 22 with one or more buffer members 40 arranged therebetween. The support seat 21 is provided with a plurality of lower guide posts 3 matched one by one with the upper guide hole grooves 2. The lower mold plate 22 is slidably mounted between the plurality of lower guide posts 3. The lower mold plate 22 is arranged parallel to and directly below the upper mold plate 11. A support plate 23 matched with the flange plate 30 is embedded in the lower mold plate 22. The lower end of the support plate 23 passes through the lower mold plate 22 and extends to the support seat 21. A plurality of guide plates 50 are arranged on the periphery of the support plate 23 on the lower mold plate 22. Each guide plate 50 is elastically connected to the lower mold plate 22. Each guide plate 50 can slide on the lower mold plate 22 along the mold closing direction under the action of the mold closing force and can return to its position under the action of the rebound force when the mold is opened.

[0026] During operation, the flange plate 30 with waste is first placed between several guide plates 50, and the mold is closed after completion. The lower guide column 3 is inserted into the upper guide hole groove 2 to guide the upper template 11 and the lower template 22. The groove 1 reserves an escape space for the flange plate 30, and the relatively raised part on the outer side of the groove 11 punches out the waste on the edge of the flange plate 30; during the stamping process, the flange plate 30 of the upper template 11 is pressed against the support plate 23, and the guide plate 50 is pressed into the lower template 22, pushing the lower template 22 to slide on the lower guide column 3 and compressing the buffer 40; when opening the mold, the upper mold 10 drives the upper template 11 away from the lower mold 20, the guide plate 50 pops out of the lower template 22 and returns to its position, and the buffer 40 pushes the lower template 22 away from the support seat 21 and returns to its position.

[0027] The utility model provides an upper guide hole groove 2 and a lower guide column 3 on the upper template 11 and the lower template 22 respectively, so that the upper and lower templates can be guided when the mold is closed. The upper and lower templates cooperate with the conventional guide parts between the upper and lower molds to improve the position accuracy of the upper and lower templates when the mold is closed, thereby ensuring the punching accuracy. By providing a groove 1 adapted to the flange plate 30 on the upper mold 10 and providing a movable lower template 22 on the lower mold 20, it is convenient to accurately fix the flange plate 30 to be punched on the lower template 22 in the mold open state, and the buffer part 40 can reduce the punching force on the flange plate 30 on the lower template 22 during the mold closing and punching process, thereby avoiding or reducing the influence of the buffer cutting operation on the contour size of the flange plate 30, thereby improving the efficiency and yield rate of punching production.

[0028] Further, such as Figure 3 As shown, the depth of the groove 1 is greater than the thickness of the flange plate 30; each buffer 40 is a spring and is sleeved on the lower guide column 3; Figure 4 As shown, each guide plate 50 is provided with a chamfer 51 on the side wall facing the support plate 23 and extending obliquely to the upper end of the guide plate 50 .

[0029] It can be understood that the deeper depth of the groove 1 can avoid scratching the flange plate 30 and facilitate mold opening; the chamfer 51 on the guide plate 50 facilitates the flange plate 30 and avoids scratching the flange plate 30.

[0030] In application, the guide plate 50 can also be connected to the electric control unit so that it can be retracted into the template 22 when the flange plate 30 is placed and rise up to guide the flange plate 30 after the flange plate 30 is basically placed in place, so as to cooperate with the automatic feeding mechanism of the flange plate to realize automated production.

[0031] Further, such as Figure 1 As shown, a plurality of support columns 4 are arranged at the lower end of the support seat 21 , and each support column 4 is integrally formed with the support seat 21 or detachably fixedly connected.

[0032] It is understandable that a number of support columns 4 can serve as reinforcing structural members to enhance the rigidity of the support seat 21 and mitigate its deformation during stamping production, so that it can provide stable and reliable support for the support plate 23 and the lower mold plate 22 and ensure their shape and position accuracy.

[0033] Further, such as Figure 1-2 As shown, a matching guide assembly 60 is also provided between the upper mold 10 and the lower mold 20; the guide assembly 60 includes a plurality of upper guide posts 61 and lower guide sleeves 62 extending along the mold closing direction and adapted one by one, each upper guide post 61 is provided on the upper mold 10 and on the outer side of the upper mold plate 11, and each lower guide sleeve 62 is provided on the support seat 21 and on the outer side of the lower mold plate 22.

[0034] It can be understood that the utility model is provided with an upper guide hole groove 2 and an upper guide column 61 on the upper mold 10, and a lower guide column 4 and a lower guide sleeve 62 on the lower mold 20. The cooperation of the two sets of guide structural parts can reduce the position deviation of the upper and lower molds after the molds are closed, ensure the relative position accuracy of the punching part 1 on the upper mold plate 11 and the flange plate 30 on the lower mold plate 22, and ensure the punching accuracy.

[0035] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
