Cause analysis and maintenance method of damage of aluminum extrusion machine parts

Usually, the failure of aluminum extrusion machine mechanical parts mainly include the following:

1, the overall fracture

The parts in the tension, pressure, bending, shear and torsion of external loads, the dangerous section will occur fatigue fracture, such as post fracture, the fracture of the bolt, gear tooth root fracture etc..

2, excessive residual deformation

If in the parts of stress exceeds the yield limit of the material, it will produce parts such as residual deformation, bending deformation of shaft gland, etc..

3, the destruction of the surface parts (mainly caused by the failure of components)

The destruction of parts of the main surface is corrosion, wear and contact fatigue, these are the failure form with a continuation of work time and occur gradually, such as rail wear, copper sleeve wear.

The failure of 4, disrupting the normal working conditions caused by

Such as sliding bearing fluid friction, only in the presence of lubricating oil film is complete only when the normal work; if the destruction of these necessary conditions, the failure will occur in different types, such as bearing overheating, scuffing and wear failure, failure belt slippage occurs.

Fault and maintenance method of aluminum extrusion machine often occurs; ask; oil valve common fault and maintenance method of aluminum extrusion; Q; aluminum extrusion machine slowly rising pressure for what reason? Look into the push rod; the proportion of current is maximum, if not, you can check the charging valve; the reaction speed is fast enough; ask; push rod current into a big, double pump and proportional solenoid valve open; turn work into the first slow after the fast, the thick material is more obvious, two a fast forward cylinder down; a; 1. in the feed, to the purity of raw materials were examined, not; must be in 3. aluminium extrusion machine

Fault and maintenance method of aluminum extrusion machine often occurs

Q; oil valve common fault and maintenance method of aluminum extrusion

Q; aluminum extrusion machine slowly rising pressure for what reason?

Look at the push rod into the ratio when current is maximum, if not, can turn to try. Look at the two voltage is too small. Try to check whether the appropriate large early turning work into

Whether the reaction speed check charging valve fast enough

Q; push rod current into a big, double pump and proportional solenoid valve open pressure from the master cylinder exhaust after 110MP 210MP

Turn into slow fast, the thick material is more obvious, the two cylinder fast overhauled glyd ring intact without leakage, pressure relief valve and two valve benefits are new, benefits flow valve pressure reaction alone soon set 240MP is there other reasons? Answer; such words are likely to be charging valve was not fast enough. Q; aluminum extrusion machine is heavy equipment of extruded aluminium. Extrusion are aluminum and Aluminum Alloy bar, work load, the wear degree is high, usually how to maintenance and upkeep of equipment?

A; 1. in the feed, the purity of raw materials to be checked, can not let the foreign body into the machine, so as not to damage the machine. 2. more than usual to check the lubrication of the transmission parts, to avoid wear and lubrication is not in place. 3. aluminum extrusion machine must reach the required heating temperature to the extrusion mould and operation in the seasoning barrel, reduce the work intensity of the profile extrusion machine. 4. screw speed, from low to high gradually increase in the cylinder idling time less than 2-3 minutes. 5. screw in the cylinder air operation time, pay attention to the working state of the main motor extrusion machine. 6. extrusion machine motor, should always pay attention to the status of their work, should avoid long time in overload condition, it will shorten its service life. Connect the 7. parts of the fixed bolt should be checked according to the standard operation, check for loose phenomenon. The 8. parts of the lubrication of each class should be checked, whether fully lubrication. 9. aluminum extrusion machine bearing temperature, should not exceed 50 DEG C. 10. screw runs, should be promptly cleaned up. 11. after the end of the day, should promptly clean up the aluminum extrusion after leaving the wreckage, packaging mold, screw, barrel cleaning.

Want to do not appear fault machine of aluminum extrusion machine, normal maintenance and maintenance is particularly important

Often the question often stops running (especially when no power), machine failure (because machine problems, so the operation failure). Below we try to understand how to maintain equipment

1, the daily care must keep up, to maintain a clean machine.

2, regular cleaning oil filter, oil pump and pump body protection circle. The new pump with appropriate temperature and thermometer to check the pump of the difference, so you can know the relative leakage of oil pump. No matter how good the sealing condition of the suction pipe, the pump has a certain suction air so they have to pay special attention to the oil tank.

3, maintenance is to accumulate experience, cllimbing more than usual on the machine by hand the machine body temperature induction.

4, the problem of maintenance records timely, prevent the next in the same fault, have a certain perception so to avoid the possibility of overhaul on the machine speed.

5, must maintain the cleanliness of hydraulic oil, a hole to surface mail fix. Especially the return pipe penetrates into the surface of the tube tank hole must be sealed with rubber hole.

Three current 6, regularly check the machine pressure, and pressure, to use current meter measurement to protect the normal operation of the motor motor to avoid burning motor or motor overloading caused a sudden shutdown.
