Four-column composite molding machine daily maintenance points?
Four-column composite molding machineAdopt four guide column guide system, adjustable, cost-effective. This series of hydraulic presses are widely used in the field of composite forming. Molding machine parameters such as table size, opening, stroke, speed, etc. can be customized according to customer requirements. The following is an introduction to the daily maintenance points of the four-column composite molding machine.
1. The working oil is recommended to use No. 32 and No. 46 anti-wear hydraulic oil, and the oil temperature is within the range of 15~60 degrees Celsius.
2. The oil is strictly filtered before it is allowed to be added to the oil tank.
3. The working fluid should be replaced once a year, and the replacement time should not exceed three months;
4. The slider should be often injected with lubricating oil, the appearance of the column should be kept clean, and the oil should be injected before each work.
5. Under the nominal pressure of 500T, the maximum allowable eccentricity of concentrated load is 40mm. Excessive eccentricity is easy to cause column strain or other undesirable phenomena.
6. Calibrate and check the pressure gauge every six months;
7. If the four-column composite molding machine is stopped for a long time, the surface of each part should be scrubbed clean and coated with anti-rust oil.
