Description
Technical field
The invention belongs to wheel and forge the field, especially a kind of wheel melts the soup forging equipment.
Background technology
Forging is that a kind of metal forming machinery that utilizes is exerted pressure to metal stock, makes it produce plastic deformation to obtain to have the processing method of certain mechanical performance, definite shape and size forging.Can eliminate the defectives such as cast condition that metal produces is loose by forging in smelting process, to optimize heterogeneous microstructure, simultaneously owing to having preserved complete metal streamline, the mechanical performance of forging generally is better than the foundry goods of same material.Cast type comprises: gravitational casting (Gravity die casting), low pressure casting (Low pressure die casting) and vacuum pressing and casting (Vacuum die casting), these casting methods are aborning because molten soup setting rate is slow, easily cause the situations such as shrinkage cavity and gas enter to occur, cause the mechanical performance difference of product very large.And, because mold temperature is too low and the factors such as injection rate of molten soup, restricting all the time forming shape and the thickness of product.In order to make up the deficiency of these casting methods, begun the research of a large amount of " forging the casting method of mode ".It is the molten soup forging method that molten soup is solidified under the state of high pressure that molten soup forges, and can make organizing of product more tight, improves the mechanical performance of product, is applicable to simultaneously carry out large batch of production.
At present, wheel is mainly the method production of adopting low pressure casting, be applied to forge wheel if will melt the method for soup forging, because centre bore and the bolt hole position at wheel center position are the most important, the words that pressure or impulsive force are concentrated, may cause the breakage at wheel center position, and also be easier to occur the situation of shrinkage cavity in the inboard center in the centre bolt hole of forging wheel.Can adopt at present increases the situation that the use amount that melts soup solves shrinkage cavity, but effect is unsatisfactory, and the wayward unification of consumption, causes to produce to waste raw material, and cost is higher.
