Air cushion top crown guide rail self-lubricating device

Abstract

The invention discloses an air cushion top crown guide rail self-lubricating device. The air cushion top crown guide rail self-lubricating device comprises a top crown and a base. Self-lubricating guide rail plates are installed on the top crown. Base guide rail plates are installed on the base. The self-lubricating guide rail plates and the base guide rail plates slide relatively. The air cushion top crown guide rail self-lubricating device is used for connection between an air cushion top crown or a hydraulic cushion top crown of a press and a base guide rail. The air cushion top crown guide rail self-lubricating device is structurally characterized in that the air cushion top crown and the base slide relatively, lubricating oil does not need to be supplied externally, and wear-proof plates inlaid into the top crown guide rails have the self-lubricating characteristics. A top crown load is normally an eccentric load, the number of movement times is large, and the top crown guide rails and the base guide rails are prevented from being abraded by each other severely. Self-lubricating materials reduce environmental pollution, the installation time is shortened, internal space is saved, and the manufacturing cost and the use cost are greatly reduced.

Description

technical field [0001] The invention relates to a lubricating device in the field of mechanical engineering, in particular to an air cushion crown guide rail self-lubricating device. Background technique [0002] The traditional way of lubricating guide rails is in the form of thin oil lubrication, with complex structure, many control procedures, many oil leakage points, high maintenance cost, poor reliability and polluting the environment. If the lubrication is not timely, the guide rail plate will be severely worn, and the stability and accuracy of the crown operation cannot be guaranteed. On the other hand, due to structural and space constraints, some products cannot be installed with rail oil receiving boxes at all. Now more and more users require that the sliding pair lubrication of the guide rail is simple, reliable, economical and environmentally friendly, so it is urgent to develop a structure to meet the needs of the development of the new situation.

[0002] The traditional way of lubricating guide rails is thin oil lubrication, with complex structure, many control procedures, many oil leakage points, high maintenance costs, poor reliability, and polluting the environment

If the lubrication is not timely, the guide rail plate will be seriously worn, and the stability and accuracy of the crown operation cannot be guaranteed.

On the other hand, due to structural and space constraints, some products cannot be installed with rail oil receiving boxes at all.
