Linear cutting guide wheel assembly with waterproof blades

Abstract

The invention discloses a linear cutting guide wheel assembly with waterproof blades. The linear cutting guide wheel assembly comprises a guide wheel, a guide wheel shaft, bearings and a guide wheel seat. An accommodation cavity is formed in the middle portion, facing the end face of the guide wheel, of the guide wheel seat, a waterproof blade assembly is arranged in the accommodation cavity and is composed of a center pipe and 2-4 blades evenly distributed on the circumferential face of the center pipe, and a waterproof cover covers the end face of the guide wheel seat. The guide wheel shaft sequentially penetrates through the waterproof cover and the center pipe of the waterproof blade assembly, then enters the guide wheel seat, and is connected with the bearings. The waterproof blade assembly is matched with the guide wheel shaft through the center pipe so as to rotate along with the guide wheel shaft. A water outlet is formed in the lowest point of the installation position of the guide wheel seat. Through the multiple waterproof structure design, the linear cutting guide wheel assembly has a better waterproof effect, lubrication oil can not easily enter the positions where the bearings are located, well waterproof protection is provided for the bearings, and the service life of the bearings is greatly prolonged.

Description

technical field [0001] The invention relates to the improvement of the wire cutting technology, in particular to a wire cutting guide wheel assembly with waterproof fan blades, which belongs to the wire cutting technology field. [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 production cycle, and low manufacturing cost. Wire c...

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
