bearing housing pillow block maintenance
Bearing bearing pillow block should pay special attention to the following points during use:
(1) Use of bearing housing pillow block cooling system.
Bearing housing pillow block cooling water not only prolongs the service life of the bearing housing, but also improves production efficiency. The material of the bearing housing is generally made of special bearing housing steel through various treatments. Even the best bearing housing steel has its limit of use, such as temperature.
When the bearing housing pillow block is in use, if the mold temperature is too high, it is easy to cause cracks on the surface of the core early, and some bearing seats have appeared on a large area before even more than 2000 mold cracks. Even when the bearing housing pillow block is in production, the mold core has changed color because the temperature of the bearing housing is too high. It has even reached more than 400 degrees after measurement. Such a temperature is prone to cracks when it encounters the chilling condition of the release agent. , The products produced are also prone to deformation, strain, sticky mold and other situations.
In the case of using bearing housing pillow block cooling water, the use of release agent can be greatly reduced, so that the operator will not use the release agent to reduce the temperature of the bearing housing. Its benefits are to effectively extend the life of the bearing housing pillow block, save the die-casting cycle, improve product quality, reduce the occurrence of sticking molds and scratches and sticking aluminum, and reduce the use of release agents. It can also reduce the loss of the ejector rod and core due to the overheating of the bearing housing.
(2) Bearing housing pillow block must be preheated during the production process to prevent the occurrence of cracks when the cold bearing seat suddenly encounters hot metal liquid, and the more complicated bearing seat can use blowtorch , Liquefied gas, mold temperature machine in good condition, relatively simple bearing seat can be preheated by slow injection.
(3) The cleaning of the bearing housing pillow block parting surface is very troublesome and easily overlooked. The operator thoroughly cleans the bearing housing parting surface with kerosene, which not only prevents the bearing housing from being squeezed Injury, and after cleaning, the exhaust groove blocked by the residue of the release agent or other dirt on the bearing housing pillow block can be opened, which is conducive to the discharge of gas in the cavity during the injection process and improves the product quality.
(4) If the bearing housing pillow block is equipped with neutron control, please note that the signal line between the die casting machine and the bearing seat is absolutely forbidden. The reason is very clear. In daily production, it is difficult to avoid water on the signal line. Or, the place where the joint is banded is easy to break, resulting in short circuit with the machine tool. If the signal is wrong, the alarm will stop automatically and the time will be delayed, and the signal will be disordered. The bearing housing pillow block will be damaged. Cause unnecessary losses. Pay attention to waterproof
