Description
Technical field
The present invention relates to a kind of screw mold, be specifically related to a kind of screw mold one two punching cover and processing technology thereof.
Background technology
As a kind of standard component be fixedly connected with, screw is seen everywhere in modern production and life.Wolfram steel a bit as one of cold forging die conventional in screw production industry, it mainly shaping (preformed) in screw head, the control accuracy of its size will meet the national standard of screw product.Existing screw mold wolfram steel one two rushes the cover lathe that adopts more and processes, and main technological process is: 1). and machining blanks raw material is cylindric barred body; 2). at cylindric bar center car endoporus; 3). cylindric bar car is broken profile, length; 4). the shaping salient point of car; 5). polishing salient point.Above-mentioned processing process is complicated, owing to relying on manual processing, therefore processes consuming time, waste of manpower more, and the stepped hole portion size of nest plate is relatively difficult to be controlled, and percent defective is high, and production efficiency is low, and the service life of two punching covers is short, and product quality cannot strict guarantee.
Need a kind of screw mold one two to rush cover and processing technology thereof, product percent of pass is high for this reason, and reduce mismachining tolerance, controlled working precision, effectively enhances productivity, and 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, reducing mismachining tolerance, controlled working precision, effectively enhance productivity, increase the service life, the screw mold one two simultaneously can saving process time and personnel cost rushes cover and processing technology thereof.
For achieving the above object, technical scheme of the present invention is as follows: a kind of screw mold one two rushes 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 described body along described body central axis, are provided with transition chamfering between described blind hole and described inner via hole, and one 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 edm forming salient point.
Preferably, the other end of described body is provided with fillet.
Preferably, described a kind of screw mold one two rushes to overlap and makes for wolfram steel or chromium steel.
A kind of screw mold one two of the present invention rushes the processing technology of cover, and this processing technology comprises:
(1) blank raw material Vehicle Processing is cylindric bar, middle preformed blind hole;
(2) profile, the length of the cylindric bar of grinding machine attrition process and step;
(3) at the center punch processing inner via hole of cylindric bar;
(4) the shaping salient point of spark machined;
(5) polishing salient point.
The beneficial effect of employing the technical program is: product percent of pass is high, and reduce mismachining tolerance, controlled working precision, effectively enhances productivity, and increases the service life, and can save process time and personnel cost simultaneously.
