Description

Forging endoporus and periphery aperture overall thermal rush technique
Technical field
The present invention relates to technical field of forging, be specifically related to forging endoporus and periphery aperture overall thermal rushes technique.
Background technology
At present in forging field, different due to various forging zero spare part, therefore, the Forging Technology used also is not quite similar, on the market some forging it comprise endoporus and some outer apertures around endoporus, but endoporus and the equally distributed some apertures of periphery are difficult to entirety in forging process to be forged or goes out, main cause can be out of shape after hot piercing, and easily note mould is difficult to de-material, so in current forging field at home, the technique of this product is first forging out, then endoporus in the middle of heat punching is carried out, finally mill out periphery aperture with milling machine or make special frock clamp drilling machine and get out periphery aperture respectively, this technique is practicable, but operation is many, cost is high, cycle is long, efficiency is low.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of preparation method, and cost is low, and the endoporus that production efficiency is high and periphery aperture overall thermal rush technique.
Technical problem to be solved by this invention realizes by the following technical solutions:
Forging endoporus and periphery aperture overall thermal rush technique, it is characterized in that, comprise following processing step:
1., blanking: arrange corresponding billet weight on cutter, allowance control is between ± 10g, and cutter blanking, then carries out shearing sub-material by cutter.
2., heating: intermediate frequency heating is to 1000-1200 DEG C, and temperature must not be too high and too low, and the too high meeting of temperature causes product burning, and the too low meeting of temperature causes product punching failure;
3., base: with 400T friction press base, blank diameter is less than mold cavity diameter 2-3mm;
4., be shaped: be shaped with 630T friction press, forging mold preheating 10-15 minute before being shaped, then the blank made is put in mold cavity and forges, blank final forging temperature is more than 800 DEG C;
5., hot piercing: the integrated tooling mould bases of ready-made red needle and endoporus drift is contained on 200T punch press, ready-made punching counterdie and mould bases are installed on punch press simultaneously, and the distortion preventing that closely cooperates bottom punching counterdie boss and forging lower recess, then the hot forging after shaping is put on counterdie boss, carries out overall punching with 200T punch press;
6., trimming: by the 200T punch press traditional method of indicating the pronunciation of a Chinese character, excise unnecessary overlap, adopt pneumatic mode to be blown off by waste material forge piece while excision;
7., isothermal normalizing: with net belt type constant-temperature oven by carrying out isothermal normalizing process, until interior tissue and hardness reach the requirement of drawing regulation;
8., ball blast: carry out Shot Blasting with apron type airless shot blasting machine to forging surface, bottom oil groove, postorder is not reprocessed, until oxide skin removed totally;
9., pack: product good for ball blast is carried out outward appearance detection, then packs, can transport or directly put in storage.
The invention has the beneficial effects as follows: the improvement of present invention process research, the invention has the beneficial effects as follows: in the present invention, determine overall thermal punching technology, after overall punching, forging is without distortion, meet technological requirement, simplify production technology, reduce production cost, improve production efficiency, pole is beneficial to be promoted and utilizes.
