Wherein, the hardness HRC of cylinder metal〉60.
Preferably, in the step 1, select the cylinder metal of hardness HRC＜60 to carry out machined, the cylinder metal after the processing is by heat treatment, cylinder hardness HRC〉60.
Because hardness HRC〉60 cylindrical material adding man-hour, and needed cutting knife hardness is higher, and equipment requirement is also higher; By the less metal of hardness is processed, make its hardness be returned to HRC by heat treated mode again〉60, processing technology is then simple a lot, and cost also reduces much.
Preferably, in the step 2, the hardness of base material is identical with the hardness of cylindrical material.
Because carrying out pressing mold when processing, base material also is subject to the extruding of cylinder, if the hardness of base material less than the hardness of cylindrical material, then installing hole may be out of shape, and causes the precision of pressing mold to reduce.
Preferably, in the step 2, base material is after carrying out the perforate processing, again by heat treatment, so that the hardness of base material is identical with the hardness of cylindrical material.
The less material of hardness is processed than being easier to, so base material can be selected the less material of hardness; After the processing, it is being heat-treated to improve its hardness.
Preferably, in the step 4, the hardness＜HRC50 of the drift material of selecting, the drift of made improve the hardness of drift by heat treatment, so that the hardness of drift〉HRC50.
The less material of hardness is carried out pressing mold when processing, and precision is higher, and easy to operate, so drift can select the material that can improve by heat treatment hardness, and hardness is less during pressing mold, and hardness improves after the heat treatment.
Heat treatment in the present specification comprises: the techniques such as annealing, quenching, normalizing, tempering.
Beneficial effect of the present invention is: the present invention can copy a plurality of drifts by master mold, and production technology is simple; Save cost.
