Abstract
The present invention relates to a machining process of machine screw tap and its special-purpose mechanically-holding type taper stamping die. Said invention adopts two steel materials, and utilzies the special-purpose mechanically-holding type taper stamping die to forge said two steel material into head portion and tail portion, then two steel materials are undergone the processes of one-step forging square tail, cutting and making central hole, using abrasive wheel to rub off the scale from end face of thermal forged piece and but-jointing two semi-finished product steel materials to obtain the invented product.
Description
Affiliated technical field
The present invention relates to the mould of a kind of machine with parts machining process and special use thereof.
Background technology
At present, existing machine tap producing process is that the high-speed steel with diameter 11mm is cut into a 85mm length with punch press; With lathe the two ends car is put down making steel become 80mm again, respectively bore a centre bore at two end faces; Is head with lathe with steel one this 8.3mm of end car growth 55mm diameter; With milling machine the cross section being milled in four processing of steel shank is foursquare square tail; With milling machine three processing of steel head is milled out three grooves.Not only processing charges is high for this machine tap processing technology, and long processing time, and step is more loaded down with trivial details.
Summary of the invention
It is few to the purpose of this invention is to provide a kind of processing charges, and process time is short, and step simply is easy to the machine tap processing technology.
Another object of the present invention provides a kind of clip type tapering diel for realizing that above-mentioned technology is special-purpose.
This achieves the above object, and technical scheme provided by the invention is: a kind of machine tap processing technology is to select a long 23mm of high speed steel diameter 9mm and the long 55mm of medium carbon steel material diameter 8.5mm for use; With the clip type tapering diel disposable formed by forging of the long 25mm of high speed steel diameter 9mm with special use, being swaged into external diameter is the long 27mm of 10.5mm; With the long 55mm of medium carbon steel diameter 8.5mm with special-purpose clip type tapering diel be installed in horizontal punching machine beat disposablely on the brain machine beat square tail, cut off, centering; Grind off hot forging end face oxide skin with emery wheel; With two semi-finished product steel butt joints.
A kind of clip type tapering diel of implementing the special use of above-mentioned technology, it comprises the middle apex of the heart, feed back plate, lower mold body, die body, formwork, punch-holder shank, feed back rod, circlip groove, formwork is fixed on the punch-holder shank, die body stretches into the formwork inner chamber, feed back rod, from punch-holder shank, stretch into the formwork inner chamber and extend in the die body, the top of die body is provided with circlip groove, be feed back plate and lower mold body below die body and the formwork inner chamber, feed back plate and lower mold body are bolted together, in the middle of the feed back plate a middle apex of the heart is housed, middle apex of the heart bottom just in time withstands on the lower mold body.
Compared with prior art, because the present invention is docked steel processing back earlier, dock afterwards earlier than prior art and process simplified processing technology.And the present invention is to machine tap threaded portion blank band centre bore, can disposable hot forging forming, after forge hot, molecular structure is closely knit, improves the quality of products, to the shank square tail, also can disposable cold-forging forming, anterior with grind finished product after shank docks, can utilize Mould Machining blank cost to reduce half, speed of production improves about five times, saves material again.
