Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a brazing anti-oxidation protection device for diamond cutting discs. Background Technology

[0002] Diamond cutting discs are high-efficiency cutting tools that use diamond particles as cutting edges and are bonded to a metal substrate through a brazing process. They are widely used in the processing of hard materials such as stone, concrete, and glass. Their performance depends critically on the quality of the brazing between the diamond and the substrate. If oxidation occurs during the brazing process, it will severely reduce the diamond's holding power and the cutting disc's lifespan.

[0003] In the brazing process of diamond cutting discs, anti-oxidation protection devices are typically used to ensure process quality. These devices generally include a sealed quartz bell jar forming a protective chamber to isolate the disc from air; an induction heating coil that rapidly heats the disc locally to the brazing temperature via high-frequency electromagnetic induction; a vacuum or protective gas system that creates an anti-oxidation environment by evacuating air or filling with inert gas; and a workpiece support mechanism to position the disc and ensure uniform heating. The working principle is as follows: the diamond cutting disc to be brazed is first placed in the protective chamber, then a high vacuum or inert gas atmosphere is created through the gas system, and then induction heating is used to melt the brazing filler metal, achieving a metallurgical bond between the diamond and the substrate. Throughout the process, the protective atmosphere continuously acts to prevent oxidation.

[0004] A search revealed a diamond saw head production device (CN201519821U), specifically an induction brazing device for manufacturing diamond saw heads, applicable to the production of diamond saw blades, frame saws, and band saw heads. This device includes a base with threaded air inlets on both sides. A rectangular quartz glass cover is also fixed to the base, with an induction coil on its outer circumference and an air outlet at the top. The quartz glass cover is bolted to a lifting mechanism. A support rod is also threaded to the base, and the saw head is engaged in a groove at the upper end of the support rod. The base is threaded to another lifting mechanism. This patent uses a sealing grease + bolted quartz glass cover sealing method, which suffers from problems such as reliance on tools for interface disassembly and assembly, low efficiency, easy wear and failure of the interface seal, and low interface alignment accuracy, easily damaging components. Therefore, a diamond cutting blade brazing anti-oxidation protection device is proposed to solve these problems. Utility Model Content

[0031] The clamping assembly includes a fixing plate 11, the outer wall of which is fixedly connected to the bottom of the base 2. A fixing seat 16 is fixedly connected to the outer wall of the fixing plate 11. A guide post 15 is fixedly connected to the inner wall of the fixing seat 16. The guide post 15 serves as the sliding length of the slide plate 12.

A clamping block 13 is fixedly connected to the outer wall of the slide plate 12. A protective cover 14 is fixedly connected to the inner wall of the clamping block 13. The clamping block 13 clamps the interface, so that the protective cover 14 can well wrap the interface.

[0032] Example 2:

[0033] Reference Figure 1 , Figure 2 and Figure 4A bracket 2 is fixedly connected to the top of the base 2. A saw blade 9 is mounted on the top of the bracket 2. The workpiece to be brazed is bonded to the saw blade 9 through a brazing process, where diamond particles are bonded to the metal matrix. An induction coil 10 is mounted on the top of the saw blade 9. The induction coil 10 generates a high-frequency alternating magnetic field, causing the saw blade 9 to generate an induced current and rapidly heat up to the brazing temperature. A bracket 1 is fixedly connected to the bottom of the base 2. A base 4 is fixedly connected to the bottom of the bracket 1. An outer shell 20 is slidably connected inside the quartz bell jar 5.

[0035] When using this diamond cutting disc brazing anti-oxidation protection device, pressing the handle 19 causes the outer wall gasket 21 to compress the spring 23, pushing the small slider 24 at the bottom to contact the ball 26. The ball 26 will then slide back into the outer shell 20, thus achieving the unlocking effect. Releasing the handle 19 will cause the spring 23 to push the block slider 25 upward to compress the ball 26, thus achieving the locking effect.
