This novel manufacturing process fluting on the tungsten steel cutter body plane, the cutter body is the I shape promptly, has reduced the contact surface in the tungsten steel cutter body processing, the effectual form and position tolerance degree of difficulty that has solved to cutter debug time in can effectual saving piston processing has promoted customer machining efficiency and machining stability.
Description
Technical Field
The utility model relates to a piston ring groove processing technology field specifically indicates PCD ring groove sword.
Background
At present, most of engine pistons are made of aluminum alloy composite materials, and along with the development of the automobile industry, the engine is light in weight and various technical requirements are improved, so that the processing requirements of aluminum alloy piston ring grooves are higher and higher.
The tungsten steel cutter body of the conventional PCD annular groove cutter is in an integral plane, and the tungsten steel cutter body can deform due to thermal expansion in the manufacturing process, so that the tolerance of the shape and position of the PCD annular groove cutter cannot be guaranteed to be less than 0.001 mm. This novel manufacturing process fluting on the tungsten steel cutter body plane has reduced the contact surface in the tungsten steel cutter body processing, the effectual form and position tolerance degree of difficulty that has solved to cutter debug time in can the effectual piston processing of practicing thrift has promoted customer machining efficiency and machining stability.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's not enough, provide PCD ring slot sword.
The utility model discloses a realize through following technical scheme, provide PCD annular sword, including tool bit and cutter body, tool bit and cutter body vacuum welding connect, the longitudinal section of cutter body is the I shape.
Preferably, the material of the tool bit is polycrystalline diamond.
Preferably, the material of the cutter body is tungsten steel.
Preferably, the depth H of the one-side groove of the I-shaped cutter body is 0.3 mm.
Preferably, the taper deflection angle of the upper end surface of the cutter head is 0.2 degrees.
Preferably, the length of the cutting head is less than 2 mm.
Preferably, the cutter head and the cutter body are both formed in one step by slow wire electrical discharge machining.
Preferably, the vacuum welding is performed by a vertical vacuum welding furnace.
The utility model has the advantages that:
this novel manufacturing process fluting on the tungsten steel cutter body plane, the cutter body is the I shape promptly, has reduced the contact surface in the tungsten steel cutter body processing, the effectual form and position tolerance degree of difficulty that has solved to cutter debug time in can effectual saving piston processing has promoted customer machining efficiency and machining stability.

Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 1 and 2, the utility model discloses a tool bit 1 and cutter body 2, tool bit 1 and cutter body 2 vacuum welding connect, the material of tool bit 1 is polycrystalline diamond, the material of cutter body 2 is the tungsten steel. The cutter body 2 is H-shaped in longitudinal section, and the depth H of the groove on one side of the H-shaped cutter body 2 is 0.3 mm.
The taper deflection angle of the upper end face of the tool bit 1 is 0.2 degrees, and the length of the tool bit 1 is smaller than 2 mm. The form and position tolerance of the cutter body 2 is less than 0.001mm, the parallelism of the cutter body 2 is less than 0.001mm, and the size tolerance of the cutter head 1 is less than 0.001 mm.
The tool bit 1 and the tool body 2 are both formed in one step by adopting slow wire electrical discharge machining. The common diamond grinding wheel PCD annular cutter is not wear-resistant and can not ensure the dimensional accuracy and the smoothness of the cutting edge. The method adopts the steps of firstly removing the allowance by slow wire-moving electric machining and then polishing by using the diamond grinding wheel, thereby not only ensuring the size, but also improving the smoothness of the cutting edge.
The vacuum welding is carried out through a vertical vacuum welding furnace, the welding strength can be improved through the vacuum welding, and meanwhile, the phenomenon that oxidation reaction is carried out with air to generate an oxidation layer to influence the quality can be avoided.
Of course, the above description is not limited to the above examples, and technical features of the present invention that are not described in the present application may be implemented by or using the prior art, and are not described herein again; the above embodiments and drawings are only used for illustrating the technical solutions of the present invention and are not intended to limit the present invention, and the present invention has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that changes, modifications, additions or substitutions made by those skilled in the art within the spirit of the present invention should also belong to the protection scope of the claims of the present invention.
