IIIMain structure and working principle

20 ton and 30 ton multifunctional electric hydraulic demoulderMain components of the frame, hydraulic system, pressure gauge, and electrical system

1Rack section

It mainly consists of crossbeams, columns, trays, oil cylinders, shells, bases, etc. The crossbeam can be equipped with demolding accessories for useφ101.6mm、φ100mm、φ50mmThe test mold is used for demolding, and the tray is used for positioning and supporting the mold barrel during demolding.

2Hydraulic system:

Composed of hydraulic pump, conversion valve, oil tank, oil filter, oil pipe, and joint

The hydraulic pump is an axial piston high-pressure pump with a flow rate of2.5m3/minrated pressure31.5Mpa, by1500KWThe three-phase motor is directly driven and fixed on the base.

The conversion valve is installed on the right side of the front panel and is operated by a manual lever. Lift the oil cylinder upwards, press the oil cylinder downwards, and stop in the middle.

The left side of the conversion valve is the overflow valve, which regulates the pressure range. This program has been debugged before leaving the factory and cannot be adjusted arbitrarily

3、Electrical system:

Composed of electric motor, start button, stop button, fuse, relay, etc

4Usage:

1Before use, first fill the fuel tank with oil6LHydraulic oil (add oil after opening the cover plate) Check whether various oil pipe joints and fasteners are loose. If they are loose, tighten them to prevent oil leakage and affect use. Check the grounding of the electrical system and whether the fuse is effective

2Operating procedures and demolding methods:

At the beginning, move the manual lever to the middle stop position, then press the start button on the panel, turn on the power, and the oil pump starts working. Move the manual lever to raise the piston a certain distance and observe for any abnormal phenomena such as jamming. If there are any, stop the machine for inspection and elimination. If there are no abnormal phenomena, raise the piston a certain distance and then lower it. Repeat this process several times to discharge the air in the cylinder, and observe that there are no bubbles in the oil pipe before normal use.

When demolding, attention should be paid to the accuracy of the positioning of the mold barrel, which is the key to the safe operation of the instrument and smooth demolding. Due to the different sizes and structures of various compaction instruments, this machine has different positioning methods for the mold, and is equipped with corresponding accessories for easy and reliable use. When demolding, the height of the tray should be adjusted first to meet different molds. Place the mold with the test block on the tray, and pay attention to accurate positioning. When the specimen is removed, the power or oil supply valve should be turned off in a timely manner to stop the piston from rising, and the manual valve should be adjusted to lower the oil cylinder toPoint, when descending to a certain height, close the manual valve.

5Maintenance and Care

1The inside and outside of the instrument should be kept clean to prevent rusting of all parts

2Regularly check the cleanliness of the oil, settle the hydraulic oil in the oil tank once a month according to usage, and replace the hydraulic oil every six months. When changing the oil, thoroughly clean the oil tank and filter. If the oil is found to be turbid and cannot be used anymore, it should be replaced in a timely manner, otherwise it will accelerate the wear of the hydraulic part, and evenAffecting normal work,

The hydraulic oil specifications and recommendations vary depending on the temperature, as follows:

（1）When the ambient temperature is15±5Used at ℃GB443-84N46(Equivalent to)30Mechanical oil)

（2）When the ambient temperature is25±5Used at ℃GB443-84N68(Equivalent to)40Hydraulic oil)

1Notes:

1It is strictly prohibited to not refuel and let the oil pump run idle

2Before use, the system must be completely emptied of air before use

3When demolding, attention should be paid to the rising distance of the oil cylinder, and it is strictly prohibited for the piston to come into contact with the test mold to prevent damage to the parts. Operators should pay special attention to this

4After completing the experiment, the piston should be placed at the bottom to prevent rusting caused by moisture on the piston

5Before use, it is necessary to read the user manual

The electric demoulder consists of a base, a gearbox with a screw, a motor, a column, demoulding, a top plate, and a bracket

1Scope of application and main parameters

This electric demoulder can be used forφ is50mmThe100mmThe101.6mm,and152mm, Gao Wei230mmVarious test molds and specimen test molds can be made using an electric demoulder when needed, which is convenient to use and reduces manpower

Main technical parameters:

（1）Rising speed of demoulder screw:94mm/min

（2）Lowering speed of demoulder screw:94mm/min

（3）Moving distance of demoulder screw:240mm

（4）Maximum lifting distance of demoulder screw（L）270mm

（5）Demoulder screwMaximum descent distance（L）30mm

IIOperation and Use

（1）Connect the power supply and check if the motor lifting is normal. When it rises94mm/min, decreased to94mm/minIf there is any abnormal adjustment, the electric demoulder is working normally.

（2）Operation process:

Place the start stop handle in the raised position, and at this point, release the lead screw and94mm/minAfter rising and the trial mold comes out, the vehicle should be stopped immediately to prevent the screw from coming out. When demolding, the upper edge of the trial mold should be aligned with the circular hole on the top plate of the demoulder (to prevent the screw from coming out)50mm、φ100mmThe test piece needs to be replaced with a detachable pressure plate. The lower end of the test piece is aligned with the release pad with a screw head, and the test barrel is supported by a bracket. As the release screw rises, the test piece can be released.

Place the start stop handle in the lowered position, and at this point, release the lead screw94mm/mindecline

Attention: The descent limit of the demoulding screw is the distance between the upper end and the upper end of the transmission box30mmImmediately stop the vehicle to prevent damage to internal components

（3）maintenance and upkeep

1Regularly keep the instrument clean and wipe it after each use to ensure the cleanliness of the demolding screw, in order to prevent dirt from entering and affecting its use

2This demoulder is only for use up to and including200KNIf the demolding or production use of force exceeds200KNThe responsibility for instrument damage caused shall be borne by oneself

3Every use6The gearbox should be replaced with butter once a month (accumulated based on continuous use time) (ordinary lithium grease butter is sufficient)
