Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for manufacturing a diamond chipsaw, and in particular, after connecting mounting pieces via a connecting strip,
It is characterized by being attached to the saw blade.

(Prior Art) A diamond tip saw is used to cut hard materials such as stone and steel. A diamond chipsaw is a steel endless band or disc with a large number of diamond chips attached at appropriate intervals to the edge, and is a saw blade with excellent sharpness for cutting hard materials. Previous diamond tip saws were attached to the band or disc by welding, which caused problems due to thermal deformation of the welded parts of the band and disc. Despite this, diamond chips were welded to bands and discs because it was thought that diamond chips had to be firmly fixed, but in reality, by doing this, diamond chips were welded to bands and discs. As the chips became asymmetrical, the impact force applied to them became stronger, resulting in the diamond chips falling off during use.

In order to solve this problem, the present inventor invented a method of attaching a diamond chip to a band or disc via a mounting piece having a U-shaped cross section.
An application has already been filed (Japanese Unexamined Patent Publication No. 58-94914). This is a mounting piece that is made by bending a metal plate into a U-shape, welding a diamond chip to the top surface of the mounting piece, and then clamping and fixing the mounting piece in a predetermined position on a band or disc. Since a simple fixing method such as spot welding, screw fixing, or gluing is sufficient for the fixing means, problems caused by welding the mounting portions of the band and disc can be completely eliminated.

By the way, the diamond chips saw formed in this way has diamond chips aligned in a row compared to previous ones, and the impact force applied to it is much smaller, but if one of the diamond chips falls off during use, A strong impact force acts on the subsequent diamond tip, which causes it to fall off, eventually rendering the diamond tip saw unusable.

(Means for solving the problem) The present invention focuses on the point that the impact force on each diamond chip is extremely small,
Each mounting piece is connected in advance and then attached to the saw blade, so that even if one of the mounting pieces loses its adhesion to the saw blade, it will not fall off and the cutting operation can continue. be.

The present invention will be specifically described below based on illustrated embodiments.

In the figure, numeral 1 is a mounting piece and 2 is a diamond chip. These are the conventional techniques already mentioned (Unexamined Japanese Patent Publication No. 58
-94914), the mounting piece 1 is bent into a U-shaped cross section with an interval equal to or slightly wider than the thickness of the saw plate 3 such as a band or disk to which it is to be attached. The diamond chip 2 is attached to the mounting piece 1.
It is fixed to the top surface using a fixing means such as welding.

Reference numeral 4 is a connecting strip that connects the mounting pieces 1. There is no particular limitation on the method of connecting the attachments 1. In short, it is sufficient to connect the mounting pieces 1 with a predetermined spacing and to ensure that the spacing does not change depending on the cutting resistance applied to the diamond chip 2.

FIG. 1 is an example of this, in which the connecting strip 4 is a sufficiently long metal strip with a width approximately the same as the thickness of the source blade 3 to which the diamond chip 2 is to be attached. The mounting piece is connected by fitting it into the top surface and welding it to the back side of the top surface. FIGS. 2 and 3 show another example in which the mounting pieces 1 are connected by integrally molding the connecting strip 4 with the mounting pieces 1.

To manufacture a diamond chipsaw, a mounting piece 1 to which a diamond chip 2 is welded is attached to a connecting strip 4.
Attachment piece 1 and connection strip 4 are welded at predetermined intervals, or after integrally molding attachment piece 1 and connection strip 4 in advance.
The mounting piece 1 is connected via the connecting strip 4 by welding the diamond chip 2 to the saw blade 3, and then the mounting piece 1 is clamped at a predetermined position on the saw blade 3.
It is attached by spot welding, screwing, gluing, or other means.

(Effects of the Invention) As described in detail above, the present invention is for attaching a diamond chip to a saw blade such as an endless band or disc made of steel. The diamond chip is connected to the saw blade at intervals, and then attached to the source blade, and by doing so, the positioning of the diamond chip with respect to the saw blade is simplified and work efficiency is significantly improved. In particular, even if some of the mounting pieces come undone from the saw blade during use, the cutting work can be continued without them falling off immediately, preventing problems caused by work stoppages and diamond cutting. This can prevent damage caused by the chipsaw becoming unusable.
