Problems solved by technology
In the traditional stamping forming process, the bending radian and angle are calculated and simulated according to the springback value and experience, and the springback is suppressed through the process to achieve the purpose of precision forming, but the springback compensation accuracy is poor, and it is vulnerable to Due to the influence of material hardness and mold precision, the machining accuracy of the bending radian and angle of the product cannot meet the process requirements, and there will be traces of secondary bending on the surface of the aluminum sheet, which will affect the appearance quality of the aluminum battery cover

The invention discloses an aluminum battery cover manufacturing method and a stamping die. The stamping die comprises a female die and a male die matched with the female die; an aluminum plate is stamped by the matching of the female die and the male die. The improvement is that the male die is provided with a heating device capable of being used to heat the aluminum plate to be stamped, the heating device heats the male die, and after the male die has certain temperature, the aluminum plate located on the male die can be heated. The aluminum plate is formed after being heated, and does not rebound, so that the condition that the machining accuracy of an aluminum battery cover is lowered caused by rebounding of a stamped aluminum sheet can be effectively avoided. According to the scheme, the aluminum plate only needs to be stamped once, and secondary stamping forming is not needed, so that machining time and machining procedures are shortened to a certain degree, the machining efficiency of the aluminum battery cover is improved, and the labor intensity of a worker is lowered.
Description
technical field [0001] The invention relates to the technical field of mobile phone processing, in particular to a method for manufacturing an aluminum battery cover and a stamping die. Background technique [0002] The processing of aluminum battery cover is generally formed by stamping aluminum sheet. In the traditional stamping forming process, the bending arc and angle are calculated and simulated according to the springback value and experience, and the springback is suppressed through the process to achieve the purpose of precision forming, but the accuracy of springback compensation is poor, and it is susceptible to Due to the influence of material hardness and mold precision, the machining accuracy of the bending radian and angle of the product cannot meet the process requirements, and there will be traces of secondary bending on the surface of the aluminum sheet, which will affect the appearance quality of the aluminum battery cover. [0003] Therefore, how to impr...
