Precautions for the use of hydraulic presses


The application of hydraulic press is very wide. Hydraulic press is also called hydraulic press. For example, embossing of metal or non-metal parts, forming, shallow stretching, laminating, trimming and cutting, etc. The common products that can be pressed are cases, watch straps, glasses frames, tableware, signs, hardware parts and other products. Then the problems and precautions encountered by operators during the use of hydraulic presses, how to deal with them, etc.

First of all, when the hydraulic press produces vibration operation in the process of use, how should it be operated and handled? When we check the hydraulic press, if the pressure is held normally, then we will see its oil pressure tube has expansion, which is an elastic deformation. It is difficult to release all of it in a short time, and its cylinder pressure will rise. We can let the hydraulic press use the check valve to keep pressure on the return stroke, which plays a great role in the hydraulic press.

When the hydraulic press produces vibration, it will potentially some problems, for these problems, described as follows:

(1) Changes in the properties or dimensions of the material or workpiece being processed.

(2) Failure of parts or auxiliary devices of the machine.

(3) External interference (such as shock, vibration, electromagnetic interference).

(4) Loss of control of the hydraulic press by the operator (especially hand-held or mobile machines).

    Precautions for the use of hydraulic presses:

(1) Calibrate the pressure gauge once every six months.

(2) Do not overload or exceed the maximum eccentric distance for use.

(3) Check regularly whether the hydraulic oil of the equipment is reduced.

(4) The working fluid should be replaced once a year, of which the first replacement time should not exceed three months.

(5) If the machine is out of use for a long time, the surface of each part should be scrubbed clean and coated with anti-rust oil.

(6) when using to observe whether oil leakage or other abnormalities, such as unreliable, noisy, vibration, etc. to stop and analyze the reasons.

(7) Operation to observe the pressure change, if the pressure does not jump to the prescribed words to turn off the power switch in time to avoid excessive pressure leading to equipment failure, while overhaul.

(8) Pay attention to safety, the operator should be trained for the job.

(9) At the end of each day's work, place the slider in the lowest position.
