Classification of the products of forging manufacturers
Produced by forging manufacturers, workpieces or blanks are obtained by forging and deforming metal components. The products of forging manufacturers can be classified according to temperature and structure. Next, I will take a closer look at the product classification of forging manufacturers.
In the processing of forgings, the products of manufacturers can be classified into cold forging, warm forging, hot forging and cold forging according to the processing temperature. They are generally processed at room temperature, while hot forging is often processed at a recrystallization temperature higher than that required by the metal composition. So what is the crystallisation temperature? According to the relevant regulations, the temperature required during recrystallisation through large cold plastic deformation, i.e. more than 70% of the deformation of the metal can be completed within a holding time of one hour, is called the recrystallisation temperature. Crystallization is in the forging annealing temperature is high enough, annealing time is long enough to produce strain in the organization of the deformed metal or alloy recrystallization core, and this organization continues to increase until the original deformation of the organization completely disappeared, so that the forging manufacturer's product performance has changed significantly. This process is called recrystallisation.
Depending on the geometry and structural complexity of the forging manufacturer's product, the die design and forging process can also be determined. Specifying the type of exercise structure is therefore a prerequisite for process design. So forgings are generally divided into three types in the factory, each of which can be divided into three groups, so that the products of exercise manufacturers are divided into nine groups. The fracture die section of this type of forging is usually urged when the axis of the body is determined to be formed in the Mortang and its horizontal direction is close to the two-dimensional dimension. Depending on their forming difficulty, they will be divided into three different groups, i.e. upsetting and micro-compression formed forgings, such as gears with little variation in hub and rim height. Extruded and slightly upsetting formed forgings, or extruded, pressed in and upsetting formed forgings, such as universal joint forks, cross shafts etc. Forgings formed by compound extrusion, such as hub axles, etc.
The main shaft of a forging manufacturer's product is shaped in one grinding cell, while a straight shaft forging with longer dimensions in one dimension in the horizontal direction is another. There are also three types of forgings according to the degree of difference in their vertical shaft forging area, one with a small or large difference in the cross-sectional area of its vertical spindle and a forging with branches at one or both ends. In addition, the spindle axis is curved in the vertical plane, but the plan view shows the product of a manufacturer of long shaft forgings that are straight.
