Linear cutting guide roller assembly capable of prolonging service life

Abstract

The invention discloses a linear cutting guide roller assembly capable of prolonging the service life. A containing cavity is arranged in the middle, facing the end face of a guide roller, of a guide roller base, a water blocking fan blade component is arranged in the containing cavity, a waterproof cover is arranged on the end face of the guide roller base in a covering mode and is provided with a center hole, an abrasion-resistant lining is arranged in the center hole, and a lubricating grease layer is arranged on the inner wall of the lining. The guide roller base sequentially penetrates through the center hole of the lining and a center pipe of the water blocking fan blade component to enter the guide roller base and to be connected with a bearing, the water blocking fan blade component is in tight fit with a guide roller shaft through the center pipe to rotate with the guide roller shaft, and a water outlet is arranged in the lowest point of the installation position of the guide roller base. The linear cutting guide roller assembly has a better waterproof effect because of multi-waterproof-structure design, plays a good role in achieving waterproof protection for the bearing because lubricating liquid and the like hardly enter the position where the bearing is located, and greatly prolongs the service life of the bearing.

Description

technical field [0001] The invention relates to the improvement of the structure of a wire-cutting guide wheel assembly, specifically a wire-cutting guide wheel assembly with a longer service life through a waterproof design, and belongs to the technical field of wire-cutting. [0002] Background technique [0003] The basic working principle of wire cutting is to use a continuously moving thin metal wire (called wire electrode wire) as an electrode to perform pulse spark discharge on the workpiece to remove metal and cut into shape. Wire cutting is mainly used to process various complex and precise workpieces. For example, wire cutting can process punches, dies, convex and concave dies, fixing plates, stripping plates, etc. It can process various micro-hole grooves, narrow slits, arbitrary curves, etc. .Wire cutting has many incomparable advantages. For example, wire cutting has outstanding advantages such as small machining allowance, high processing precision, short pro...

AI Technical Summary

Problems solved by technology

Emulsion or lubricant needs to be injected during wire cutting to wash away the metal shavings produced by cutting and cool down. However, these liquids will also enter the bearing and guide wheel seat while playing their own role, causing damage to the bearing. , leading to a shortened lifespan

Although prior art has also carried out waterproof treatment to it, effect is not very good
