Commonly used casting equipment for bearing rings are air hammer, crank press, boring machine, casting furnace and so on.
1. Air hammer air hammer consists of some work (piston, hammer and anvil), some power transmission (Motor, pulley, crankshaft, etc.), some operation and fuselage (tightening cylinder, working cylinder, column and base); The rotary motion of the curved shaft causes the air in the compacting cylinder to be contracted or inflated; the air passes through the air passage communicating between the working cylinder and the tightening cylinder and the valve for controlling the air passage; entering the upper or lower chamber of the working cylinder; and then operating the hammer The movement of the pole.
Air hammer is used to produce bearing ring forgings; mainly for small batch and larger ferrule forgings; free forging and hammer forging; large noise during operation.
2. Crank press crank press mainly consists of working organization (composed of crank, connecting rod and slider), transmission system (motor, pulley, transmission shaft, etc.) and fuselage; the motor rotates the crankshaft through the pulley; the crankshaft Turn the rod through the connecting rod to move up and down; then work.
The crank press is suitable for stamping of sheet metal parts, die forging of ferrule forgings (especially production line).
3. The expansion machine has some operations (pressing wheel, cylinder, rolling roller), some control (signal roller, air valve, control system, etc.), body composition. The ring blank is placed on the rolling roller during operation; The rotating rolling wheel is pressed against the ring blank under the effect of the cylinder pressure; the ring blank is deformed after the ring blank is touched; the ring blank and the rolling roll are rotated under the effect of friction; the ring blank is tightened and the wall thickness is reduced. ┐螅 ┐螅 被 被 饩 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢 恢瞥觯 瓿 瓿 兹 Φ Φ 恼 恼 恼 恼.
4. The heating of the casting furnace has great influence on the connotation quality, data utilization rate, production power, energy consumption, working conditions, labor intensity and environmental protection of the forgings. The quality of the heating depends on the layout of the heating equipment and the fuel. The current domestic heating furnace can be divided into coal stove, oil stove, gas stove and electric furnace according to the fuel type; the forgings produced by the coal stove account for half of the total output value; the electric furnace is less than 10%.
