1 Piece Forged Wheels Forming Method
1 Piece forged Wheels Forming method
Forging forming methods and classification there are many, of which the main method of forging forming is free forging and die forging. So let's take a look at the forging forming method today.
First, free forging is a simple and flexible method of metal forming, although for small and medium-sized forging batch or mass production of the case, the free forging is recognized as an outdated, uneconomical forging
But for the production of small batches or units, especially large forgings, in the hammer or hydraulic press for free forging, but still a suitable, economical production methods.
Second, the forging is the main process of forging forming, the main equipment used forging hammer, an anvil hammer, crank press, screw presses and high-speed hammer and so on. Die forging productivity, forging size stable
Set, the material utilization rate is high, so it is widely used for forging batch and mass production. It is estimated that the number of forging parts, accounting for about 90% of the total weight of forgings.
In fact, forging and forming in addition to free forging and a variety of forging the basic method, there are some other special forming methods, such as electric upsetting, cold extrusion, rotary forging, roll forging, rolling rolling,
Magnetic forging, superplastic forming, hydrostatic forming, suspension forging at home and abroad nearly 20 years of rapid development. This special forging forming technology, will be a strong impetus to the processing industry,
The above is the more common forging forming method and classification. Wheel forging deformation process is the preparation of the most important part of the free forging process. To consider the technical level of the operator and
Experience, equipment conditions, tool support, raw material supply, production and management level and other factors.
In general, the wheel forging deformation process selection, according to the shape of the forging, size and technical requirements, combined with the deformation of the forging process characteristics, with reference to the specific process specific to determine.
Wheel forging deformation process includes: to determine the necessary forging forming the basic processes, auxiliary processes and finishing process, determine the order of the process, design process size.
Hollow type wheel forging deformation process includes: to determine the necessary forging forming the basic processes, auxiliary processes and finishing process, determine the order of the process, design process size. Change of wheel forgings
Shaped technology, generally need to upsetting, punching. Some slightly trim can be achieved forging size, and some need to expand the hole inside the hole, and some need to pull the mandrel to increase its length, the specific process
The program depends on the geometric dimensions of the forging. The forging process is selected according to the specific dimensions of the forging. It must be noted that the hollow type of wheel forging process plan to choose the line, are in a certain production conditions
Under the experience of the summary, with limitations, should be used when the analysis.
