Abstract
The utility model relates to a hard alloy tool structure used for cutting stone. The hard alloy tool structure comprises a metal base and at least two hard alloy tool bits. Radial blind holes which are equal to the hard alloy tool bits in number are arranged on the circumferential face of the metal base at equal intervals. The radial section of each radial blind hole is multilateral. The front end of any hard alloy tool bit is in a cone shape and the rear portion of the any hard alloy tool bit is in a prismoid shape. The section of the rear portion of any hard alloy tool bit is matched with the radial section of each radial blind hole. The rear portion of each hard alloy tool bit is inserted into the corresponding radial blind hole. The front portion of each hard alloy tool bit and the circumferential face of the metal base of which the periphery is provided with the radial blind holes are connected in a bead weld mode. The rotation of the hard alloy tool bits in the radial blind holes can be prevented. The hard alloy tool structure is suitable for cutting hard rock and capable of ensuring cutting efficiency and the service life of a tool as well.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to cutting element, particularly hard alloy cutter, and concrete is a kind of carbide cutter tool lamps structure for cutting stone material.
Background technology:
In prior art, include the carbide bit of a metal pedestal and more than two number for the hard alloy cutter of cutting stone material, metal pedestal is provided with the radial blind holes equating with carbide bit number equally spacedly along its outer circumference surface, the radial section of radial blind holes is rounded, the front end of carbide bit is coniform, and rear portion is cylinder.Insert in radial blind holes and by being welded and fixed at the rear portion of carbide bit.In use, when carbide bit runs into solid rock, easily in radial blind holes, rotate, affect cutting efficiency and cutter life.
Summary of the invention:
The purpose of this utility model is to provide a kind of carbide cutter tool lamps structure for cutting stone material, and the described this carbide cutter tool lamps structure for cutting stone material will solve the technical problem that easily rotates, affects cutting efficiency and cutter life when prior art carbide bit runs into solid rock in radial blind holes.
This carbide cutter tool lamps structure for cutting stone material of the present utility model, comprise the carbide bit of a metal pedestal and more than two number, metal pedestal is provided with the radial blind holes equating with carbide bit number equally spacedly along its outer circumference surface, wherein, it is polygonal that the radial section of the radial blind holes described in any one is all, it is coniform that the front end of the carbide bit described in any one is all, the rear portion of any one carbide bit is all prism, the cross sectional shape at the rear portion of any one carbide bit all with the radial section form fit of radial blind holes, a radial blind holes is inserted at the rear portion of carbide bit separately.
Further, the front portion of carbide bit is connected with the metal pedestal outer circumference surface built-up welding of radial blind holes periphery.
Further, the radial section of any one radial blind holes is all square or regular hexagon.
Operation principle of the present utility model is: the radial section of radial blind holes is polygonal, the rear portion of carbide bit is prism, insert in radial blind holes and by being welded and fixed at the rear portion of carbide bit, can prevent that carbide bit from rotating in radial blind holes.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model is set to polygonal for the radial section of the radial blind holes in the metal pedestal of the hard alloy cutter of cutting stone material, the rear portion of carbide bit is processed as to prism in sintering process, insert in radial blind holes and by being welded and fixed at the rear portion of carbide bit, can prevent that carbide bit from rotating in radial blind holes, while being applicable to cutting solid rock, cutting efficiency and cutter life are guaranteed.
Accompanying drawing explanation:
Fig. 1 is the schematic top plan view of the carbide cutter tool lamps structure for cutting stone material of the present utility model.
Fig. 2 is the partial schematic diagram of the metal pedestal of the carbide cutter tool lamps structure for cutting stone material of the present utility model.
The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, carbide cutter tool lamps structure for cutting stone material of the present utility model, comprise the carbide bit 2 of a metal pedestal 1 and more than two number, metal pedestal 1 is provided with the radial blind holes 3 equating with carbide bit 2 numbers equally spacedly along its outer circumference surface, wherein, the radial section of the radial blind holes 3 described in any one is all polygonal, the front end of the carbide bit 2 described in any one is all coniform, the rear portion of any one carbide bit 2 is all prism, the cross sectional shape at the rear portion of any one carbide bit 2 all with the radial section form fit of radial blind holes 3, a radial blind holes 3 is inserted at the rear portion of carbide bit 2 separately.
Further, the front portion of carbide bit 2 is connected with the metal pedestal 1 outer circumference surface built-up welding of radial blind holes 3 peripheries.
Further, the radial section of any one radial blind holes 3 is all square or regular hexagon.
The operation principle of the present embodiment is: the radial section of radial blind holes 3 is polygonal, the rear portion of carbide bit 2 is prism, insert in radial blind holes 3 and by being welded and fixed at the rear portion of carbide bit 2, can prevent that carbide bit 2 from rotating in radial blind holes 3.
