Talking about the selection of hand tools for four column hydraulic press
browse: time:2017-10-08
As far as the four column hydraulic machines are concerned, we still need to rely on manual and material handling. In order to solve this problem, we can use the hand tools to carry out four column hydraulic machines. A lot of tools by hand, general purpose pliers, hand hook, tweezers, clamp, suction and process all kinds of special tools, is the means of safe operation.
First, four column hydraulic machine hand tools design and selection should pay attention to the following points:
1. fit in with ergonomic requirements
The handle shape of the hand tool is suitable for the hand control of the operator, and can prevent the hand from holding forward or forward when it is forced, and can not reach the unsafe position and avoid being damaged by the improper use of the tool.
2., the structure is simple and inconvenient to use
The position of the hand tool shall be in accordance with the shape of the blank to be clamped, reliable, agile, fetch and correct.
3. not to hurt the formation of mold hand tools should take soft materials manufacturing, in order to prevent unexpected conditions, tools are not timely exit the die, and die in the closed form, hydraulic machine overload.
4.. Agree with the safety of hand held electric tools. Hand hold electric tools should adopt safe voltage and protect insulation. Need to emphasize that during normal operation, the use of hand tools to keep down the punching conclusive can play a certain role but hand tools itself does not have the basis function safety, so it is not safe to install. It can only replace the hand into the risk zone, can not avoid the operator's hand accidentally into the risk zone. The use of hand tools must also be accompanied by safe installation.
Two, four column hydraulic machine through the level of oil purification to determine the machine oil change times, given several plans:
1, visual oil change method. It is by maintenance personnel experience, according to some oil to change the status of visual practices - such as oil black, smelly and milk into red, the choice can change. This approach depends on the experience of the operator.
2 sampling and assaying. Sampling, testing and determination of oil in four column hydraulic press are carried out
