Bearing seat wear repair method and steps

The conventional method generally uses post-weld machining to repair, and the surfacing causes the surface of the component to reach a very high temperature, causing deformation or cracking of the component, and the downtime is greatly prolonged by machining to obtain the size. The use of Fushui blue polymer composite material for on-site repair has no thermal influence, and the thickness of the repair is not limited. The wear resistance of the product and the concession of the metal material are not guaranteed, ensuring 100% contact fit of the repaired part. Reduce the shock and vibration of the equipment and avoid the possibility of wear. On-site repair, avoiding machining methods, saves a lot of downtime for the company and creates greater production value.

Repair steps:

1. Surface treatment, it is necessary to repair the surface of the bearing seat to remove oil and moisture;

2. Reconcile and repair materials;

3, the material is applied, the material is evenly applied to the repaired part of the bearing seat, and the filling is strong;

4. Wait for the material to solidify, and heat the surface of the material to accelerate the curing of the material.

The general bearing chamber wear can be repaired in 3-6 hours, the operation is simple and easy to learn, no special equipment and special training are required, and the “advanced” technology such as laser welding and cold welding saves time and effort, and the cost is only 1 for general repair cost. /5-1/10, on-site repair is to reduce equipment repair time and transportation costs.

The above is the introduction of the repair method and steps of the bearing seat wear. By comparison, we know that the repair with the polymer composite material has a greater advantage, and this method is simple to operate and saves time. For enterprises, time is the output value, that is, profit, so the polymer composite repair method is the best choice for enterprises to repair the worn bearing housing.

What are the points of attention for the use of the bearing housing?

1. The use of the bearing housing cooling system. The housing cooling water not only prolongs the service life of the housing but also improves production efficiency when used correctly. In actual production, we often overlook its importance. In order to save trouble and save costs, some companies have saved the use of the cooling system, which has serious consequences. When the bearing housing is in use, if the mold temperature is too high, it is easy to cause cracks on the surface of the core early, which will also affect the products produced. The use of cooling water also reduces the loss of the ram and core due to overheating of the housing.

2. The bearing housing must be preheated during the production process to prevent the sudden occurrence of hot metal liquid in the cold bearing housing and the occurrence of cracks in the turtle. The more complicated bearing housing can use the blowtorch or liquefied gas. The mold temperature machine with good condition, the relatively simple bearing seat can be preheated by slow injection.

3, the cleaning of the bearing seat parting surface, this is very troublesome, it is easy to be ignored. If the boss has a high starting point and buys a good bearing seat, the work is much easier. If the quality is not good, it is inevitable that there will be flash or dirt on the bearing part parting surface during production. The operator should always clean these. Part. If it is not removed in time, the bearing parting surface is easy to collapse, causing aluminum to run during the production process. Once this result is caused, the possibility of complete repair is small and the quality of the product is affected.

4. If the bearing housing is equipped with neutron control, it is absolutely forbidden to block the signal line between the die casting machine and the bearing housing, because in daily production, it is difficult to avoid water on the signal line or the place where the joint is wrapped. It is easy to break, which causes short circuit with the machine tool. If the signal is wrong, the alarm will automatically stop and delay the time, and the signal will be disordered, and the bearing seat will be damaged and cause unnecessary loss.

The above points explain the points that should be paid attention to during the use of the bearing housing. Since it is the main point, it is worthy of paying more attention to it. Otherwise, it is easy to make mistakes in this process, resulting in unnecessary losses and even more serious consequences. The embankment of a thousand miles is destroyed by the ant colony, so the operator should have a very big sense of responsibility, handle every detail, and don't try to save trouble.
