After the strip enters the blanking-stretching-trimming die, after the punch descends, the blanking punch shears the material, the process of blanking the wafer is about to be completed, the punch descends again, the stretching punch pulls the cut wafer into the stretching die, the stretching process is about to be completed, the punch descends again, after the stretching height reaches a design value, the trimming punch knife edge reaches the stretching die, the punch descends again, the trimming punch enters the stretching die to complete the trimming action, and thus the blanking to stretching of the strip is completed, and the trimming process is completed after the stretching is completed.
The die has a simple structure, three procedures of wafer discharging, stretching and trimming are completed in one die, the die processing cost is low, and meanwhile, the labor cost is saved.
The flange edge after stretching is trimmed under the condition of becoming irregular, so that the flange edge is convenient for the positioning of each subsequent process, the deviation and the concentricity degradation are not easy to generate, the positioning is more accurate, the stripping is more uniform and better, the personnel operation is easy and not hard, the wall thickness of each subsequent process is more uniform, the jumping degree is less, the dynamic balance quantity can be smaller, and the motor operation is more uniform. The production convenience of the single-station die is improved, the die development cost is low, the die development time is short, and the die assembly and debugging are convenient and quick. The die has low cost and high production efficiency, and solves the problem of high cost caused by products produced by continuous dies or multi-station dies.
The object of the present utility model is fully effectively achieved by the above-described embodiments. Those skilled in the art will appreciate that the present utility model includes, but is not limited to, those illustrated in the drawings and described in the foregoing detailed description. While the utility model has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the utility model is not limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the scope of the appended claims.
