The hammer rod piston quickly completes the return
The electrical 62 Series Ball Bearings
part includes: main motor, cooling motor, electric control box, button station, etc. b. The high pressure nitrogen drives the piston to drive the hammer head to strike, referred to as 'air pressure drive, hydraulic energy storage'. The oil chamber at the lower part of the accumulator is directly connected to the main control valve, and the upper part is connected to the gas cylinder group through the pipeline.
Special valves and safety valves include: main control valve, quick discharge valve, insurance Valves, Hall switches, etc. Among them, the liquid-gas electro-hydraulic hammer has become more mature through continuous innovation. At the same time, the upper part of the piston makes the hammer head under the action of gas pressure and the weight of the hammer head system. The body part includes: left and right body, left and right guide rails, base (free forging), etc. ⑷. Designed 'X'-shaped rail structure:
The comb-shaped rail of domestic steam-empty forging hammers exists The disadvantages of short force arm, over positioning, and no temperature compensation function. The piston separates the oil at the lower part from the nitrogen at the upper part. The upper cavity of the hydraulic hammer cylinder is high-pressure nitrogen, and the lower cavity is high-pressure oil, so early electro-hydraulic hammers are prone to occur b. With the rapid development of modern hydraulic technology and electronic control technology, electro-hydraulic hammers have gradually developed, especially in the 1980s. Gas cylinders: nitrogen cylinders, gas Bottle holders, gas collectors, high-pressure ball valves, etc.
Therefore, when we carry out the 'head changing' transformation, for the multi-cavity forging and large eccentric load die forging hammer, we still use the 'rigid thick hammer rod theory' of the steam-air forging hammer, and achieve satisfactory results. The surface of the hammer shaft has been rolled to improve the surface hardening layer, thereby increasing the service life of the hammer shaft. The hammer rod piston quickly completes the return stroke of the hammer head under the action of high pressure oil.; ⑺. Technological innovation
