The so-called tire die forging parts is the process of producing tire die forging parts using the tire die on the free forging hammer. When the tire die forging parts, the mold is not installed on the equipment, but independently placed on the lower anvil, the blank is placed in the lower die chamber, the upper die is closed, the hammer anvil strikes the upper die, through the upper die to transfer the load to the blank to make it deformed.
It can be seen that the tire die forging accessories have the characteristics of both free forging and general die forging. The mold is simple, the process is advanced, the production preparation cycle is short, the cost is low, and it is suitable for the production of small and medium-sized batch die forging parts. However, the precision of the tire die forging parts is low, the productivity is low, the life of the tire die is short, and the labor intensity is high.
According to the shape characteristics of tire die forging accessories can be divided into many types, including circular shaft, disc, long rod and multi branch. The circle can also be divided into step shaft and flange shaft, the former is composed of a number of steps with different diameters or smooth cross-section changes, transmission shaft, gear shaft transmission lever, etc.; The latter is composed of a larger diameter flange head and a smaller diameter shaft, valve, half shaft, flange shaft, etc.
The disc type tire die forging accessories, more representative flange, according to the flange position is divided into end flange, middle flange and double-sided flange; Gear includes change gear, bevel gear, thin spoke gear, etc. Ring sleeve, according to the ratio of wall thickness and height of large forging, is divided into flat ring and sleeve; And a cup shell, with a deep through the hole.
In addition, long rod type tire die forging accessories also include a lot of products, such as lever, tie rod, ring and other straight rod; Crankshaft, hook, bearing cover and other bending rod; Branch rod, valve body and other branch rod and fork joint, fork and other fork rod. The multi-branch type of tire die forging belongs to the short axis of the non-rotating body, the more commonly used are multi-channel valve body, cross shaft, etc.
These are the types of tire die forging accessories. There are obvious differences between them and they are also used in different occasions, but the requirements for their quality are the same as strict, so as to ensure the normal use of the whole mechanical equipment.
