Description
Technical field
The invention belongs to mechanical manufacturing fields, more particularly to big specification (20 or more φ) high temperature closes in standard component production industry
Golden hot forming, a kind of suitable devices improved and optimizated using punching machine.
Background technology
The use that high temperature alloy material is produced in mechanical manufacturing field especially aircraft engine fastener is especially frequent,
And the product of most of high-temperature alloy materials is acquisition better fatigue life head to be required during being manufactured into bolt
It is processed in such a way that shape is made in upsetting, since material intensity itself is very high, forming is compared for the bolt of big specification (M20 or more)
It is difficult.It is usually followed successively by conjunction with the processing method of the high temperature alloy hexagon socket head cap screw of existing manufacture level specification M20 or more：Under
Material, copper facing, hot upsetting, annealing, drilling (prebored hole before six sides in pressing), punching press (six sides in pressure), general vehicle (the interior hexagonal hole bottom of removal
Iron filings).
Currently, during actual processing, such process route process is excessive and leads to low production efficiency, clamping times
More, line position tolerance is not easy to ensure, often occur in hexagonal and screw thread polished rod decentraction the phenomenon that, lead to product rejection, thus
Process centralized optimization can improve production efficiency under the premise of ensureing quality.The invention is punching machine in high temperature alloy hexagon socket head cap screw
Improving and optimizating in production not only can be improved productivity, but also product quality made to be improved, and solve the above problem, simple and direct efficient.
Invention content
The invention is intended to provide a kind of high temperature alloy hexagon socket head cap screw punching press optimization method, to solve current hexagon socket head cap screw
The low problem of yield rate.
In order to achieve the above object, base case of the invention is as follows：A kind of high temperature alloy hexagon socket head cap screw punching press optimization
Method includes the following steps：
Step a：By the raw material heating and melting of bolt, blanking, copper facing, hot upsetting, annealing are then carried out successively and forms hair
Embryo bar；
Step b：Blank bar in step a is heated at high temperature and is put into lower die.
It is further comprising the steps of：
Step c：Need circumferentially to be removably connected on the end face in upper mold towards lower die just stamping punch, fine punch and
