The cushion and the pre-compression spring are fixed

Due to the large partial strike 68 Series Ball Bearings of multi-cavity forging, and the severe cold strike during the final forging, the guide rail is damaged severely in the early stage, and even the phenomenon of 'hammer stuck' occurs.; ⑷. Improve the design of the secondary valve and increase the area of ​​the orifice, thereby increasing the flow rate and velocity during the slow drop process.　　When lifting the hammer, you only need to manipulate the main valve to make the high pressure oil in the oil pump accumulator communicate with the lower cavity of the main cylinder piston.　　

But for multi-cavity forging die forging hammer to implement 'head change' transformation, 'flexible thin hammer rod theory' is obviously not applicable. According to the principle of tribology, 3 sets of tensioning structures (compression piece, taper sleeve, hammer rod) are designed to make the hammer rod by The original 'double cone structure' is changed to a 'single cone structure', which greatly avoids the occurrence of stress concentration, thereby achieving both reliable connection and convenient disassembly. The hydraulic station part includes: oil tank, motor-oil pump unit,

Electronically controlled unloading valves, valve seats, electronically controlled thermometers, heat exchange motor pump units, heat exchangers, oil filters, etc. The electro-hydraulic power head, its main body is a tank, which is used as a short-term oil tank during operation (when not working, the oil in the tank enters the oil tank of the hydraulic station placed on the ground through the oil retu pipe), with eight bolts passing through

The cushion and the pre-compression spring are fixed at the original cylinder position. In the past, “free forging electro-hydraulic hammers are not free”.2mm), which makes the forging process The eccentric force is boe by the hammer head rail, which greatly improves the life of the hammer shaft. According to the different sealing oil and gas sealing media, choose Ky rings with different Shore hardness.
