Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an upper cover continuous mold. Background Art

[0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the required parts. The quality, production efficiency and production cost of stamped parts are directly related to mold design and manufacturing. The level of mold design and manufacturing technology is one of the important indicators of a country's product manufacturing level, and largely determines the quality, efficiency and new product development capabilities of the product.

[0003] A continuous die refers to a cold stamping die in which a press machine uses strip-shaped stamping raw materials to complete multiple stamping processes simultaneously on a die using several different workstations in one stamping stroke. Each time the die completes a stamping operation, the material strip moves a fixed distance until the product is completed.

[0004] In traditional stamping processing, for products with bent edges on both sides, such as Figure 1 As shown, a metal product of an upper cover has a first bending edge and a second bending edge on both sides, and usually adopts a step-by-step stamping and bending process. That is, a set of stamping dies is first used to punch the material strip into a size suitable for bending, and then the punched material is transferred to another set of bending dies for bending processing to achieve the shape requirements of the final product. This step-by-step processing method has some problems, such as:

[0005] 1) Low production efficiency: The sheet needs to be transferred between two sets of molds, which increases production time and operation steps.

[0006] 2) High labor cost: The transfer of sheets usually requires manual operation, which increases labor costs.

[0007] 3) Product quality consistency is difficult to ensure: multiple clamping and transfer may affect the accuracy and consistency of the product.

[0008] In order to solve these problems, researchers began to try to integrate the punching and bending steps into a set of continuous molds. However, since the blanks will be separated from the strip after punching, they can no longer be transferred to the bending station by pulling the strip. This requires improvements and innovations in the structure and working mode of the mold to achieve punching without affecting bending and ensure smooth processing and quality stability of the product.

[0009] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

[0035] In the technical solution of the utility model, a specific punching structure is cleverly provided on the connecting plate 8 of the material strip 3 to achieve effective integration of the punching and bending processes. Specifically, through the cooperation of the punching knife and the punching groove on the punching station 5, the material strip 3 is located on the connecting plate 8 to form the first partition hole 13 and the second partition hole 14, and combined with the design that the first partition hole 13 is located outside the first bending edge 9 and the second bending edge 10, and the second partition hole 14 is located between the two, that is, through this spacing cooperation, while achieving the punching and separation of part of the sheet, the connection end 15 that can connect two adjacent workpieces is retained, so that the sheet can still be moved to the bending station 6 with the material strip 3 through the connection end 15 for subsequent processing after punching, thereby effectively ensuring the smooth processing and quality stability of the product, effectively improving production efficiency and saving costs.

[0036] In the embodiment of the utility model, the punching station 5 includes a first punching station 16 and a second punching station 17.
