Automatic molding machine use precautions and fault check
After the automatic casting molding machine is put into production, it is necessary to pay attention to the fault detection of the automatic casting molding machine. Otherwise, the machine will easily malfunction. The fault detection of the molding machine is mainly carried out from five aspects, including the indenter part of the molding machine, the shock part, the compacting part, the demoulding part, and the operation.
First, the indenter part of the automatic molding machine fault detection
After the automatic molding machine is used for a period of time, the indenter may have a slow and slow swinging motion, and the molding machine should be maintained in the following manner.
1. When the molding machine is in fault detection, check the gap between the front and the back of the molding machine's indenter. Is there any foreign matter obstruction such as iron shovel?
2. Open the two intake pipes on the back of the indenter. The control valves are respectively placed in the original position and swinged in to see if the intake of the nozzle is large enough. If the intake air volume is small, the pressure of the indenter will be slow. When the molding machine is faulty. If this is the reason, the valve can be checked until the air filter is cleaned and blocked.
3, the automatic molding machine has a cover on the indenter, open to observe whether the rack is rusted seriously, if this molding machine malfunctions, it will also cause the head to be slow, can be cleaned with kerosene or gasoline.
4. If the above situation does not occur during the fault detection of the automatic molding machine, open the flanges on both sides of the indenter to check whether the Y-rings on both sides of the rack are aging and deformed. If so, the head may be slow. .
5. Open the upper flange located behind the molding machine head and check whether the butter of the gear bearing has deteriorated. If this is the case, flush with kerosene or gasoline, and move the pressure head at the same time, it will feel looser and looser.
Second, the shock part of the automatic molding machine fault detection
There are several reasons for the shock or weakness of the fully automatic molding machine:
1. The automatic molding machine fault detection encounters air filter gas blockage. Because the vacuum pump works to generate some water, the filter element in the air filter gas is blocked by some foreign matter in the pipeline for a long time. Looking at the pressure is not small, but the air flow is not enough, causing the machine to be weak.
2. Due to long-term vibration, the following molding machine failures will occur: 6 M20 hexagonal nails connected to the shaking table and the shock piston are loose, so that there is a gap between the shaking table and the piston, and the working airflow leaks from here, causing a shock. Powerless, especially after compaction, can not be shocked.
3, the piston and the pump iron are not lubricated, rusting, can also cause shock and weakness, solve the problem of the molding machine, can open the rubber tube to the earthquake table, inject a pound of kerosene or gasoline, and then go up, When the shock is turned on, the sound of the shock will change significantly.
