Failure and solution of hydraulic cylinder in Hot forging Press
The hydraulic cylinder in the hot forging press plays a great role in its work, but the use of the time will inevitably appear fault problems, the following will tell you about the methods to deal with the failure.
1. In an environment where the temperature is too low, the viscosity of the hydraulic oil will become larger and the liquidity will become worse, thus slowing down the action of the hydraulic cylinder of the press, and the action will gradually fail, and it is necessary to replace the hydraulic oil with good viscosity and temperature performance.
And in the case of low temperature, you can use the heater to increase the oil temperature at start-up.
Forging equipment is used more and more in life, hydraulic parts is one of its components, so how to solve its noise fault?
Let's give you a specific introduction.
1. Excessive wear of the internal components of the hydraulic pump, such as wear and tear of the cylinder block and distribution plate, plunger and plunger hole of the piston pump, resulting in serious leakage in the hydraulic pump, flow pulsation will occur when the hydraulic pump outputs high pressure and small flow oil.
Cause high noise.
In this case, the deflection angle of the pilot system variable mechanism can be appropriately increased to improve the influence of internal leakage on the output flow of the pump.
Punch is widely used in electronics, communications, computers, household appliances, furniture, vehicles, hardware parts and other stamping and forming, the following is a brief introduction to its placement attention.
Forging process in the application of life is also more, but there are many friends do not know much about it, the following is a brief introduction to the three major functions of forging technology.
1. Forging can change the structure of metal and improve the properties of metal.
After hot forging, the original as-cast loose, pores, micro-cracks, etc., are compacted or welded; the original dendritic crystals are broken to make the grains finer; at the same time, the original carbide segregation and uneven distribution are changed.
The forging operation machine upsetting of forging equipment is a forging process which reduces the blank height and increases the cross-sectional area.
Upsetting process is mainly used for forging gear billet and round cake forgings.
Hot forging press is an indispensable high precision forging equipment in modern forging production, but after a long time of use, there will also be corresponding faults, such as brake and lubrication system failure, the following is a specific introduction.
