The role of travel switch in hydraulic press

Share This Post

The travel switch is mainly used to convert the mechanical displacement into an electrical signal, so that the running state of the motor can be changed, so as to control the mechanical action or be used for program control. The real use of the travel switch is in industry, where it cooperates with other equipment to form more complex automation equipment. There are many such travel switches on the machine tool, which are used to control the travel of the workpiece movement or automatic tool feed to avoid collision accidents. Sometimes the travel switch is used to automatically reverse the direction of the controlled object between the two specified positions, so as to obtain continuous reciprocating motion. The travel switch is a switch with a wide range of applications. Next, let’s talk about the function of the travel switch in the hydraulic press.

How many limit switches are there on the hydraulic press?

On the hydraulic press, there are two stroke switches, which are the upper stroke switch and the lower stroke switch. The up-stroke switch is the closing action switch, and the down-stroke switch is the return switch. When the hydraulic press is working, it stops working when it reaches the upper stroke switch, and automatically returns when it reaches the lower stroke switch.

On the control box or on the oil pump?

This depends on your specific purpose. If your hydraulic system is electrically driven, then your travel switch may be the travel control switch of the oil cylinder, or it may be that when the multi-way valve is opened, the travel switch is turned on together to control the electric The closing and opening of the system is like the lever switch on the electric forklift. If it is the hydraulic pressure controlled by other systems, it may be installed on the hydraulic cylinder to control the length of the extension and retraction of the hydraulic cylinder.
