Work method for continuous stamping die for arch elastic sheet of mobile phone

Abstract

The invention discloses a work method for a continuous stamping die for an arch elastic sheet of a mobile phone. The work method comprises the steps that firstly, after a copper sheet material enters the stamping die, middle hole rough stamping is conducted; secondly, the copper sheet material advances by one position, and small holes in the two sides are subjected to rough stamping; thirdly, the copper sheet material advances by one position, and middle hole reverse forming stamping is conducted; fourthly, the copper sheet material advances by one position, and middle hole fine stamping is conducted; fifthly, the copper sheet material advances by one position, and the small holes in the two sides are subjected to fine stamping; sixthly, the copper sheet material advances by one position, and arch first forming stamping is conducted; seventhly, the copper sheet material advances by one position, and arch second forming stamping is conducted; and eighthly, the copper sheet material advances by one position, and finished product blanking punching is conducted. By means of the above manner, the work method is simple and practical in design structure, installing and adjusting are convenient, the continuous stamping die for the arch elastic sheet of the mobile phone is used for conducting a series of machining such as forming and trepanning on the arch elastic sheet of the mobile phone, machining procedures are optimized, manpower and material resources are saved, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to a punching die, in particular to a working method of a continuous punching die for bow-shaped shrapnel of a mobile phone. Background technique [0002] Various shrapnels are widely used in daily life, for example, they are used for mobile phone keys, remote control keys, and the like. These shrapnel have a specific shape to meet their working needs, and processing these shrapnel requires a stamping die. The common production method is to shape the shrapnel as a whole first, and then perform a series of hole opening processes. Omissions in processing occur, the accuracy of the product cannot be guaranteed, and the production efficiency is low. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a working method of the mobile phone bow-shaped shrapnel continuous stamping die, which has a simple and practical design and structure, and is easy to install and adjust. ...
