In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 to 11, the utility model provides a stone material graver with insection structure, including base member and sword base, the handle of a knife of base member as installation sword base can install on professional equipment or instrument, generally, and the base member can adopt structures such as cylinder or cuboid, and the terminal surface of the one end of not installing the sword base is provided with the chamfer, and the diameter/width of cylinder or cuboid structure can be between 6mm-16mm, and the total length behind the installation sword base can be 40mm-45mm. The base may be a first base 12 comprising the cutting tip and the shank, or may be a second base 22 comprising only the shank. The whole cutter blank is of a flat structure and is provided with a cutting edge. The end of the base body is provided with an installation part for installing a cutter blank, the cutter blank comprises a connection bottom surface and a connection side surface, and the installation part comprises a receiving bottom surface and a receiving side surface. The connecting bottom surface is in a tooth pattern shape, the receiving bottom surface is in a tooth pattern shape corresponding to the connecting bottom surface, and the tooth pattern shape of the connecting bottom surface is embedded with the tooth pattern shape of the receiving bottom surface and is connected with the receiving bottom surface in a welding mode. Thereby the cutter blank is welded and connected on the basal body to form the integral structure of the cutter blank and the basal body. The main cutting edge of the knife blank protrudes out of the base body, at the moment, the auxiliary cutting edge does not protrude out of the base body generally (or protrudes out of the base body but has a different deflection angle from the main cutting edge), and when the base body rotates, the knife blank is driven to rotate, so that the effect of cutting or carving stone materials by only utilizing the main cutting edge is achieved. The utility model discloses a set up the installation department and install the sword blank, set the gomphosis structure of profile of tooth shape to the connection bottom surface of sword blank and the installation department of corresponding with it accepting the bottom surface, can increase the welding area of sword blank and base member to form limit structure, and then can strengthen the joint strength of sword blank and base member, reduce the ease that the sword blank drops the base member.
The front tool face of the tool is 0.2-0.5mm higher than the center of the tool, when the tool is used as an engraving tool for engraving marble or other hard stones, the tool is required to have a tougher structure and a more wear-resistant cutting edge, and the front tool face is higher than the center of the tool, so that the tool has higher strength and is not easy to break. In addition, chamfers can be added on both the end cutting edge and the secondary cutting edge, interference can be eliminated through the arrangement of the chamfers, and influence on cutting of the main cutting edge is avoided when the cutter rotates.
The connecting side surface of the knife blank and the bearing side surface of the mounting part corresponding to the connecting side surface can have a gap before welding, namely, the connecting side surface of the knife blank and the bearing side surface of the mounting part are not directly attached before welding, because the connecting bottom surface of the knife blank is already embedded and connected with the bearing bottom surface of the mounting part through a insection structure, if the connecting side surface is attached to the bearing side surface again, the welding quality can be influenced because of over-positioning or inconsistent deformation. Because the material of sword base and base member is different, the coefficient of thermal expansion is different, can produce the inconsistent condition of deflection when the welding, through the setting in clearance, can improve this situation, avoid the deformation extrusion and influence the welding effect.
The width of the end edge of the cutter blank can be 0.2mm-2mm, and the inclination angles of two side surfaces (the lower side surface and the upper side surface) forming the end edge relative to the radial section of the cutter blank are respectively a first back angle and a chamfer angle, wherein the first back angle can be 25-35 degrees, the chamfer angle can be 25-35 degrees, and the angle sizes of the two can be equal or different. The two ends of the end edge are respectively connected with the main cutting edge and the auxiliary cutting edge, wherein the main cutting edge is used for playing a main cutting role, and the auxiliary cutting edge does not play a cutting role under a normal condition. When a tool (especially a tool with a larger diameter) rotates, if the auxiliary cutting edge participates in cutting, the interference with the main cutting edge is easy to occur, therefore, only one cutting edge participates in cutting, the contour shape is easier to guarantee, and the tool is more suitable for the tool with the larger diameter.
The cutter blank can adopt a polycrystalline diamond compact, polycrystalline diamond (PCD) is an artificially synthesized product, diamond powder is used as a raw material and is sintered at high temperature and high pressure, and the hardness of the polycrystalline diamond compact can reach HV 4000-10000.
