And welding flux is arranged between the PCD blade and the cutter body, and the PCD blade and the cutter body are bonded together through the welding flux by heating.
In the current welding structure, only the cutter groove matched with the blade structure is arranged at the corresponding position on the cutter body, in the welding process, the welding flux is easy to control badly, the welding seam is not tightly controlled, the welding seam is extremely easy to be too large, even the welding seam is subjected to false welding and sheet falling, the welding strength is poor, the welding flux overflows too much to form accumulated tumors in some cases, the appearance is extremely poor, high points behind cutting edges are easy to generate, and the cutter is made to lose efficacy. This problem is exacerbated with the increasing number of forming tools available today.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to above-mentioned defect, provide the PCD welding cutter that has ceramic coating, cutter intensity is good, and welding quality is good, avoids appearing the condition such as rosin joint, solder accretion, improves the result of use of cutter.
The utility model provides a technical scheme that its technical problem adopted as follows:
the PCD welding cutter with the ceramic coating comprises a cutter body and a PCD blade, wherein the front end of the cutter body is provided with a welding groove for welding the PCD blade, the surface of the PCD blade and the surface of the front end of the cutter body, which corresponds to the joint of the PCD blade, except the surface of the welding groove, are provided with the ceramic coating,
an arc-shaped sunken accommodating groove is arranged in the welding groove close to the outer side, a plurality of matching grooves which are uniformly distributed are arranged in the welding groove at the inner side of the accommodating groove, the depth of the accommodating groove is greater than that of the matching grooves,
the bottom end surface of the PCD blade is provided with a matching bulge corresponding to the matching groove and a containing stop bulge corresponding to the containing stop groove, the height of the containing stop bulge is less than the depth of the containing stop groove,
the groove surface of the welding groove corresponding to the outside of the containing groove is an inclined surface from outside to inside, and an inclined surface connecting part matched with the inclined surface structure is arranged at the position corresponding to the PCD blade.
Furthermore, the structure of the matching protrusion is matched with the structure of the matching groove, and the matching grooves are in smooth transition.
Furthermore, a communicated pore channel is arranged between the matching grooves, and one end part of the pore channel is communicated with the containing stopping groove.
Furthermore, a convex block which protrudes upwards is arranged in the accommodating groove.
Furthermore, the included angle between the inclined plane and the horizontal plane is 3-5 degrees.
The utility model has the advantages that: by adopting the scheme, the arrangement of the accommodating groove and the matching groove can improve the welding connection strength of the blade and the cutter body, can avoid the formation of accretions at welding seams by redundant welding fluxes, improves the quality of the welding seams, improves the using effect of the cutter, reduces the welding difficulty, facilitates the welding operation, and promotes the improvement of the production efficiency of the cutter.
