Embodiment 1

[0044] The embodiment of the present application discloses a process for processing a sintered diamond circular saw blade. refer to figure 1 and figure 2 , a sintered diamond circular saw blade processing technology includes the following steps:

[0045] S1: The steel strip passes through the punch press to stamp the primary center hole, sawtooth, and process hole. The diameter of the primary center hole is smaller than the design diameter of the product center hole, and the diameter of the primary center hole is 2mm smaller than the design diameter of the product center hole. The thickness of the substrate is 2mm. The diameter is 250mm. Afterwards, there are reinforcement grooves on both sides of the substrate. The reinforcement grooves extend from the edge of the substrate to the center of the substrate. The depth of the reinforcement grooves is 1 / 5 of the thickness of the substrate. All reinforcement grooves on both sides of the substrate Interlaced with each other, any ...

Embodiment 2

[0050] The difference with Example 1 is:

[0051] A kind of sintered diamond circular saw blade processing technology comprises the following steps:

[0052] A1: Leveling, check the flatness and stress of the substrate obtained in S1, when the flatness of the substrate is greater than 0.9mm or the stress is greater than 0.4mm, perform the pre-processing step, otherwise do not perform the pre-processing step and directly perform S2; pre-processing step Including, while flattening the substrate (flattening pressure 80KN), keep warm at 800°C for 14h;

[0053] S2: The diamond powder is pressure-formed in the position of the cutter head and the reinforcement groove of the machine body. The diamond powder is the same as in Example 1. The pressure of the pressure forming is 155 tons, and the time is 3 seconds to obtain the initially formed circular saw blade;

[0054] S3: Pressurize and sinter the initially formed circular saw blade. The pressure and sintering pressure is 140KN, the...

Embodiment 3

[0056] The difference with Example 1 is:

[0057] A kind of sintered diamond circular saw blade processing technology comprises the following steps:

[0058] A1: Leveling, check the flatness and stress of the substrate obtained in S1, when the flatness of the substrate is greater than 0.9mm or the stress is greater than 0.4mm, perform the pre-processing step, otherwise do not perform the pre-processing step and directly perform S2; pre-processing step Including, while flattening the substrate (flattening pressure 100KN), keep warm at 850°C for 12-18h;

[0059] S2: The diamond powder is pressure-formed at the position of the cutter head and the reinforcement groove of the machine body. The diamond powder is the same as in Example 1. The pressure of the pressure-forming is 160 tons, and the time is 5 seconds to obtain the initially formed circular saw blade;

[0060] S3: Pressurize and sinter the initially formed circular saw blade. The pressure and sintered pressure is 200KN, ...

Abstract

The invention relates to a sintered diamond circular saw blade machining process. The sintered diamond circular saw blade machining process comprises the following steps that S1, a steel belt is punched into an initial center hole, sawteeth and auxiliary holes through a punching machine, the diameter of the initial center hole is smaller than the designed diameter of a product center hole, edgingis conducted, and a base body is obtained; S2, the base body and diamond powder are subjected to pressure forming, and an initially-formed circular saw blade is obtained; and S3, the initially-formedcircular saw blade is subjected to pressure sintering, then the position of the initial center hole of the initially-formed circular saw blade is punched and reamed while the initially-formed circularsaw blade is hot, and the center hole with the designed diameter is obtained. The sintered diamond circular saw blade machining process has the effect of high center hole precision.

Description

technical field [0001] The present application relates to the field of diamond circular saw blades, in particular to a process for processing sintered diamond circular saw blades. Background technique [0002] Sintered diamond circular saw blades are an important part of diamond tools, mainly used in the cutting of stone and building materials. [0003] The middle part of the diamond circular saw blade is provided with a central hole, and the central hole is used to install the diamond circular saw blade on the equipment that drives it to rotate. The processing of sintered diamond circular saw blades needs to sinter the diamond powder and the body in a sintering furnace. During the sintering process of the substrate, the inner hole will become smaller to a certain extent, and the accuracy of the center hole of the substrate cannot be guaranteed. Contents of the invention [0004] In order to improve the precision of the central hole, the present application provides a pro...
