Problems solved by technology

However, a spacer is set between the saw blade bodies of the two saw blades, and its disadvantages are: the friction area between the cutting elements of the two saw blades is large, the saw blade body is easily deformed, and the service life of the paired saw blades is short; There are small gaps between them. During the working p

Abstract

The invention discloses paired saw webs. The paired saw webs comprise the first saw web and the second saw web which rotate in the reverse directions and are coaxial, wherein, each saw web comprises around substrate and sawteeth on the periphery of the round substrate; the axis of the first saw web and the axis of the second saw web are provided with installation holes which are the same in size;superhard alloy tool bits are arranged on the sawteeth, and the superhard alloy tool bit of the first saw web is opposite to the superhard alloy tool bit of the second saw web; the first saw web is uniformly provided with at least three S-shaped noise reduction lines, and at least eight cooling and chip removal holes are uniformly distributed on the second saw web in the circumferential direction; and the side surface, facing towards the second saw web, of the superhard alloy tool bit on the first saw web is attached to the side surface, facing towards the first saw web, of the superhard alloy tool bit on the second saw web.

Description

technical field [0001] The invention relates to a saw blade, in particular to a pair of saw blades. Background technique [0002] Paired saw blades that rotate in opposite directions on the same axis have the advantages of faster cutting speed and stable work than single saw blades, so they have been widely used. The technical solutions of the existing paired saw blades are all provided with a spacer between the two mutually matched saw blades to prevent the cutting elements from colliding with each other. For example, the patent with the application number 02812228.3 discloses a pair of saw blades. The two saw blades rotate coaxially and in opposite directions. In the middle of the two saw blades, a spacer extending into the gap between the two saw blades is connected. onto the blade body of at least one saw blade. The spacers thereon consist either of radially extending cutting elements on one of the saw blades, or by spacer rings or surface coatings on either blade, whi...
