Roller forging machine application field

Roll forging machines are mainly used for pre-forging and final forging of forgings. It is also possible to use air hammer, friction press, screw press, crank press and other other forging methods to form a forging consumable line. Automated rolling of steel using robots or robots.


Roll forging can be divided into rough roll forging and forming roll forging. Blank roll forging refers to a blank of medium shape and size required for die forging. The forming roll forging directly consumes the forgings in accordance with the medium shape and the size.


The essence of roll forging deformation is the rolling delay of the slab, the section of the slab becomes smaller, and the surface area increases. When the section deformation is large, multiple rolling is required. The process imagination is mainly the reduction, contraction and elongation deformation of the steel for each step. They depend on the deformation conditions such as roll diameter, medium shape and size, blank temperature, cooling and slipperiness. One end of the blank is subjected to a process of squeezing the die of the segment and clamping and deforming (initial molding), then inputting it into the gap without gaps, then rolling (preforming) and withdrawing; according to the needs of the deformation, The process multi-roll EXT slowly forms the desired molded part (final forming). Russia. This is the counter roll forging gate diameter for each application. When the change of the feed biasing roll is not uniform, it is called positive forging. When the workpiece bites in, release the clip immediately. A common roll forging machine is a single-support roll forging machine supported by the side of the frame. It has a lower rigidity and can obtain a lower precision forging. The roller diameters of various specifications are 250-1250 mm, and the corresponding roll forging force is 400-4000 kb. Some single-bearing roll forging press rolls are being trimmed at one end. This is a compound roll forging machine that combines a cantilever and a single support. Longitudinal rolling forging and transverse stretching of the ends of the cantilever are achieved. In the large-scale rolling steel consumption, robots are widely used in workpiece transfer, consumption process automation, lifting consumption rate, and increasing labor intensity.


Layout imagination


The overall imagination is given to the single column support mechanism, and the lower low forging roll is changed by two frame supports. The upper and lower forging rolls can be equipped with a plurality of fan forging dies to counter the rolling of the workpiece. The center distance of the forging roller and the angle adjustment mechanism of the forging roller can adjust the center distance of the forging roller and the misalignment angle of the forging roller mold. The scheduling of forging roll gaps and angles is very convenient.
