Background technology
As a kind of standard component that is fixedly connected with, screw is seen everywhere in modern production and life.A bit as one of cold forging die commonly used in the screw production industry, its main moulding (preformed) is in screw head for wolfram steel, and the control accuracy of its size will satisfy the national standard of screw product.Existing screw mold wolfram steel one the two punching cover lathes that adopt are processed more, and main technological process is: 1). and the machining blanks raw material is cylindric barred body; 2). at cylindric bar center car endoporus; 3). with the disconnected profile of cylindric bar car, length; 4). car moulding salient point; 5). the polishing salient point.Above-mentioned processing process is complicated owing to rely on manually processing more, so process consuming time, waste of manpower, the relatively difficult control of the stepped hole portion size of nest plate, percent defective is high, production efficiency is low, the service life of two punching covers is short, product quality can't strict guarantee.
Need a kind of screw mold one two punching cover and processing technology thereof, product percent of pass is high, reduces mismachining tolerance for this reason, the controlled working precision, and Effective Raise production efficiency increases the service life, and can save process time and personnel cost simultaneously.
?
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of product percent of pass high, reduce mismachining tolerance, the controlled working precision, Effective Raise production efficiency increases the service life, and can save screw mold one two punching cover and the processing technology thereof of process time and personnel cost simultaneously.
For achieving the above object, technical scheme of the present invention is as follows: a kind of screw mold one two punching cover, comprise body, blind hole, inner via hole, salient point and step, described body is cylindric, described blind hole and described inner via hole are arranged in the described body along described body central axis, are provided with the transition chamfering between described blind hole and the described inner via hole, and an end of described body is provided with described step, one end face of described body is provided with salient point, and described salient point is the edm forming salient point.
Preferably, the other end of described body is provided with fillet.
Preferably, described a kind of screw mold one two punching cover is made for wolfram steel or chromium steel.
The processing technology of a kind of screw mold one two punching cover of the present invention, this processing technology comprises:
