Description

Accurate slitting saw of industry aluminium alloy

Technical Field

The utility model relates to an accurate slitting saw of industry aluminium alloy.

Background

In the field of aluminum profile processing, as the requirements of users on the size precision and the smoothness of a cutting surface are higher and higher, the size precision is not high and the processing life is short due to the adoption of an integral high-speed steel saw blade.

Disclosure of Invention

In order to overcome the problems, the utility model provides a precision can not only be guaranteed, saw bit cutting life is prolonged moreover in addition, the accurate slitting saw of industrial aluminium alloy of improvement production efficiency.

The utility model adopts the technical proposal that: the utility model provides an accurate slitting saw of industry aluminium alloy, is including the saw bit base member and the wolfram steel tool bit that have the mounting hole, and the outer fringe circumference of saw bit base member is equipped with the sawtooth, is equipped with tooth bottom chip groove between the adjacent sawtooth, and the welding has the wolfram steel tool bit on the saw bit base member toothholder of the meeting of sawtooth to cutting direction, and the cutting face of wolfram steel tool bit is met to cutting direction, the blade of wolfram steel tool bit is the oblique type that one end height one end is low, the outer circumference equipartition of saw bit base member has the radiating groove, and the contour line of radiating groove comprises continuous S-shaped section, big circular arc section, small circle arc section smooth connection, and the circular arc head of radiating groove is towards the centre of a circle of saw bit base member.

Furthermore, the HRC hardness of the saw blade matrix is 42-46.

The utility model has the advantages that: the tungsten steel tool bit with enough strength and long service life is ground and processed into an oblique shape by a high-precision machine containing an oblique processing program, so that the cutting effect can be realized; and through setting up the radiating groove, it is easier that the cutting edge dispels the heat, makes the saw bit cutting light and fast. Not only can ensure the precision and the smoothness, but also can prolong the cutting life of the saw blade and improve the production efficiency.
