D51 vertical ring rolling machine equipment applicable scope and working conditions:
1. This machine is mainly used for hot rolling of ring-shaped parts blanks made of ordinary carbon steel, alloy steel, bearing steel and other materials.
2. The blank must be rolled and expanded within the forging temperature range of the part. Large rings and special rings must be expanded or multi-fire rolled. The shape and size of the blank must comply with the rolling and expanding process requirements of the D51 equipment. Special rings must be made according to the special billet making process, and the holes must be expanded or rolled in multiple fires. Wall thickness difference of blank: ≤10mm
Host requirement
1. The main body is welded with high-quality steel plate and the welding parts are annealed to eliminate welding stress and ensure long-term stability and no deformation of the parts. The guide rail surface in the fuselage is guided by rectangular guide rail, and the guide rail surface in the fuselage is replaceable guide rail plate with copper alloy, which has high strength and long life.
The overall appearance of the fuselage is smooth and beautiful, the slider guide surface has a long stroke, reasonable force, good rigidity and long service life.
2, the main slider is composed of a slider body, rolling wheel (mold), sleeve (mold seat), bearings and other parts; Roller spindle adopts double support structure. The sliding block is welded with high quality steel plate and annealed. The spline shaft and shaft sleeve are made of 42CMo alloy steel. The rolling wheel is fixed by end face and circumference, which is convenient for mold processing and replacement. Roller support bearing adopts rear structure, roller wall thickness space is large
