Description

Technical Field

[0001] The utility model relates to the technical field of diamond tool head manufacturing, in particular to a tool head charging mold frame for diamond tools. Background Art

[0002] The diamond segment is the working body of the diamond saw blade. The segment of the diamond saw blade is composed of diamond and matrix binder. Diamond is a superhard material that plays the role of cutting edge, and the matrix binder plays the role of fixing diamond. The manufacturing process of the diamond saw blade segment can be described as the sintering process of metal powder under a certain pressure. It is a powder metallurgy process: uniformly mixed metal powder is at high temperature (800-1000℃) and certain pressure (180-250Kgf / cm2). Through a series of physical and chemical infiltrations such as diffusion, welding, combination, and recrystallization between powder particles, a sintered body with a certain shape and mechanical function is formed, which is the segment.

[0003] The patent with publication number CN206306273U discloses a diamond tool bit loading mold frame, including a mold frame, wherein the mold frame includes a first frame, a second frame, a third frame, a fourth frame and a buckle, wherein buckles are welded at both ends of the first frame and the third frame, and slots are provided at both ends of the fourth frame and the second frame. The buckles installed at both ends of the first frame and the third frame are clamped in the slots opened in the fourth frame and the second frame. Graphite to be sintered is placed in the mold frame, and clamping devices are provided between the graphite to be sintered and the first frame and between the graphite to be sintered and the second frame. The clamping device includes a first fixed block, a second fixed block, a locking device and a fixed block, and the first fixed block and the second fixed block are installed on the locking device.

[0004] The diamond tool bit loading mold frame has a simple structure, low cost, is easy to assemble and disassemble, and has a strong ability to clamp materials.

[0005] However, the mold frame still has the following problem: the mold frame makes the first fixed block and the second fixed block approach each other through the mutual cooperation between the threaded rod and the nut, driving the fixed blocks to contact the graphite to be sintered, thereby achieving the mold frame's tightening effect on the graphite. However, in actual use, when the nut is manually twisted, it is difficult to ensure that the threaded rod exerts the same force on the first fixed block and the second fixed block, and it is easy for the first fixed block and the second fixed block to move at different distances, thereby causing the fixed blocks to tilt, making it difficult to effectively improve the mold frame's tightening effect on the graphite.
