Description
Technical field
The utility model belongs to machine-building technical field of auxiliary equipment, is specifically related to the forging mold that a kind of structure is simple, can reduce valve body molding cost.
Background technology
At present, valve body many employings free forging method is produced, flat-die forging utilizes impulsive force or pressure to make metal all directions Free Transform between upper and lower anvil face, unrestricted and obtain a kind of processing method of the forging of required form and size and certain mechanical performance.Cause crackle and depression etc. when heating the situation such as insufficient, forging temperature is too low, the improper and forging method of forging cooling is wrong, and billet weight is comparatively large in forging process, causes the expense wave of material, the product surface forged is coarse, and surplus is bigger than normal; Mould forging refers to first by METAL HEATING PROCESS, becomes liquid or softening state.Again it is put into mould, close disposal molding by the conjunction of the upper and lower mould of mould, sometimes need repeatedly.When using mould forging, not only improve model surface roughness and interior mechanics performance, and owing to using manipulator to coordinate during operation, make more convenient operation, the more important thing is and can alleviate billet weight, reduce costs.Therefore, in order to reduce valve body manufacturing cost, improve the quality of valve body manufacture and make manufacture process operation easier, it is very necessary for researching and developing a kind of forging mold that can reduce valve body molding cost.
Utility model content
The purpose of this utility model is to provide the forging mold that a kind of structure is simple, can reduce valve body molding cost.
The purpose of this utility model is achieved in that and comprises blocker and finisher, and described blocker comprises lower flat anvil, loose tool and upper flat anvil, arranges loose tool between described lower flat anvil and upper flat anvil; Described finisher comprises lower flat anvil, shaping mould, fixed die and upper flat anvil, arranges fixed die, be arranged to pattern in described fixed die between described lower flat anvil and upper flat anvil.
The manufacture valve body grinding tool of the utility model design is divided into blocker and finisher, the loose tool inner chamber of blocker is set to step groove and cylinder chamber, valve body model is carried out just being shaped die forging, the shaping mould inner chamber of finisher arranges step groove, cylinder chamber, groove and conical cavity, conform to the general configuration of valve body, by finisher, die forging is again carried out to first forming model, the valve body model surface roughness obtained is little, interior mechanics performance is good, and save material by the model that blocker and finisher deal, reduce cost.The utility model structure is simple, workable, not only increases the quality of valve body model, more saves molding materials, brings conveniently, reduce cost to following process.
