Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal product stamping, and in particular to a forming and curling die structure. Background Technology
[0002] Because the production process requires the product to be rolled at the ends, the product is formed by turning the edges from the inside out, which is a relatively complex process. Currently, the mold requires at least two processes or welding to complete, which is inefficient. Utility Model Content
[0003] To solve the above problems, this technical solution provides a forming and curling die structure.
[0004] To achieve the above objectives, the technical solution is as follows:
[0005] A forming and hemming die structure includes an upper die, which has a stamping part for cooperating with the inner cavity of the product to be processed, and a first hemming groove on both sides of the stamping part. It also includes a lower die, which has a receiving cavity for accommodating the product to be processed, and the receiving cavity has a second hemming groove opposite to the first hemming groove.
[0006] In some embodiments, a first arcuate transition is provided at the edge of the first crimped groove.
[0007] In some embodiments, the edges of the second crimping groove are provided with a second arc-shaped transition.
[0008] In some embodiments, the second crimped groove is provided with a guide arc surface between the two second arc transitions.
[0009] The beneficial effects of this application are:
[0010] This application has corresponding edge-rolling grooves in the upper and lower dies. When the product to be processed is in the lower die, the upper die presses the product. Due to the presence of the edge-rolling groove, the two ends of the product are turned outward along the shape of the groove, so that the edge-rolling process can be completed in one process, which greatly improves the production efficiency. Attached Figure Description
[0011] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.
[0012] Figure 1 This is a schematic diagram of the structure of an embodiment of the present utility model. Figure 1 ;
[0013] Figure 2 This is a schematic diagram of the structure of an embodiment of the present utility model. Figure 2 . Detailed Implementation
[0014] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear and understandable, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.
[0015] Please refer to Figures 1-2 The utility model discloses a kind of forming hemming die structures, including upper die 1, the upper die 1 is equipped with the stamping part 3 for cooperating with the internal cavity of product 2 to be processed, the stamping part 3 both sides are equipped with first hemming groove 4, further including lower die 5, the lower die 5 is equipped with the accommodation cavity 6 for accommodating product 2 to be processed, the accommodation cavity 6 is equipped with second hemming groove 7 opposite to the first hemming groove 4.
[0016] The present application is equipped with corresponding hemming groove on upper die and lower die respectively, then product to be processed is stamped by upper die when in lower die, because of the existence of hemming groove, to make the both ends of product outward flanging along the shape of groove, so that hemming process can be completed in one pass, and production efficiency is greatly improved.
[0017] Specifically, product to be processed is higher than lower die ≤T*4mm (T is product material thickness).
[0018] The structure of the present application is more simple after simplification, can effectively reduce a preforming process, product surface is more natural and beautiful, greatly reduce product processing length, and production efficiency is improved.
[0019] In the embodiment, first arc transition 8 is provided at the edge of the first hemming groove 4, which is beneficial to the product flanging inward again after flanging.
[0020] In the embodiment, second arc transition 9 is provided at the edge of the second hemming groove 7, and guide arc surface 10 is provided between the two second arc transitions 9.
[0021] So that the product is flanged through a specific shape, thereby forming the required product shape.
[0022] The above is only the preferred embodiment of the present application, and is not used to limit the scope of the present application, other principles and basic structure and the present application are same or similar, all within the protection scope of the present application.
