JPS62193720A - Curved clamping cutter for metallic thin different-shaped material - Google Patents

Abstract

PURPOSE:To finish a cut end to look attractive, by providing protrusive plates to be opposed in both sides of a part, crossing at a right angle with a saw blade, on a surface plate of a cutting machine and placing a metallic thin different-shaped material to be cut on said protrusive plates to be clamped and cut by the saw blade. CONSTITUTION:A metallic thin different-shaped material B is placed on protrusive plates 3 and pressed by fluid pressure clamps 4, 4 mounted to both sides of said protrusive plates. The material B, being pressed as in the above, is tensely shaped by flexing a cut part slightly to an arc shape. The different- shaped material B, in which said arc-shaped part is cut by a saw blade 1, is cut under a condition that the different-shaped material B reduces a chatter and a noise. A cut end is finished attractive because it is formed in a V-shaped by the clamps 4.

Description

DETAILED DESCRIPTION OF THE INVENTION A.Objective of the present invention The thin metal profiled material is cut using hard round steel, but the profiled material has a large chatter when the saw cuts into it during cutting. The purpose is to prevent bending and noise caused by chatter.

0 Structure of the Invention As shown in the drawings, the present invention includes a cutting machine A equipped with a saw blade 1 having a required protruding plate 3 on both sides of the orthogonal area between the surface plate 2 of the cutting machine A and the saw blade L provided above the surface plate 2. The thin metal irregularly shaped material B to be cut is mounted on the protruding plate 3, and the thin metal irregularly shaped material B is placed on the protruding plate 3.
This relates to a configuration in which a hydraulic or air pressure clamp 4 is provided at a more appropriate outer position. The saw is a hard circular saw, and the protruding plate 3 is preferably made of brass. 5 indicates a bent portion.

-・0 Effects of the present invention Since the present invention is constructed as described above, when pressure is applied by the clamps 4 installed on both sides of the thin metal profile B, the cutting part of the saw blade 1 is bent slightly into an arch shape and becomes tensioned. In order to
It is possible to reduce chatter at the cutting part as much as possible to make the cutting smooth.

Therefore, since chatter is reduced, noise can also be reduced. In addition, since the cut end of the cut is made into a V-shape by the clamp 4, there is no need to form a curved part when the cutting edge of the saw hits the cut end, thereby making it possible to finish the cut 1 beautifully. It is.
