Detailed Description
In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Example 1:
referring to the attached drawings, the invention adopts an inner annular groove machining numerical control turning tool of an O-shaped rubber ring mould with a 45-degree parting surface, and comprises a cutting part and a tool handle 4, wherein the cutting part is fixed at one end of the tool handle 4 and comprises a front tool face 2, a rear tool face 3 and a cutting edge 1; the intersection of the rake face 2 and the flank face 3 is a cutting edge 1, and the section of a cutting edge formed by the rake face 2, the flank face 3 and the cutting edge 1 is a circle with the radius of R1. As shown in fig. 2(b), the rake face 2 is connected to the holder 4 by an arc-shaped curved surface and a machined surface. The rake angle gamma formed by the rake face 2 and the horizontal plane is 16 degrees; the main clearance angle alpha formed by the rear cutter face and the vertical plane is 9 degrees; a main deflection angle kappa gamma formed by an upper tangent line of the circular section of the cutter tip and a horizontal axis is 45.5 degrees; the minor offset angle kappa' gamma formed by the lower tangent of the circular section of the cutter tip and the horizontal axis is 45.5 degrees.
Example 2:
referring to the attached drawings, the invention adopts an inner annular groove machining numerical control turning tool of an O-shaped rubber ring mould with a 45-degree parting surface, and comprises a cutting part and a tool handle 4, wherein the cutting part is fixed at one end of the tool handle 4 and comprises a front tool face 2, a rear tool face 3 and a cutting edge 1; the intersection of the rake face 2 and the flank face 3 is a cutting edge 1, and the section of a cutting edge formed by the rake face 2, the flank face 3 and the cutting edge 1 is a circle with the radius of R1. As shown in fig. 2(b), the rake face 2 is connected to the holder 4 by an arc-shaped curved surface and a machined surface. The rake angle gamma formed by the rake face 2 and the horizontal plane is 18 degrees; the main clearance angle alpha formed by the rear cutter face and the vertical plane is 11 degrees; a main deflection angle kappa gamma formed by an upper tangent line of the circular section of the cutter tip and a horizontal axis is 45.5 degrees; the minor offset angle kappa' gamma formed by the lower tangent of the circular section of the cutter tip and the horizontal axis is 45.5 degrees. The whole cutter is a hard alloy bar, and the cutter handle 4 is an unsharpened hard alloy bar.
Example 3:
and (3) profiling the inner annular groove of the rubber ring mold by using a numerical control turning tool with a tool nose R1 smaller than the annular groove R of the rubber ring mold and combining a numerical control programming technology.
The requirement on the roughness of the inner ring groove of the rubber mold is high, so that the front angle gamma of the cutter is sharp when taking 16-18 degrees, the cutting resistance is small, the cutting heat is small, and the better processing roughness is convenient to obtain;
the main function of the main clearance angle alpha is to reduce the friction between the rear cutter face and the workpiece processing part, so as to improve the surface quality of the workpiece and prolong the service life of the cutter. The increase of the main back angle can make the cutting edge of the turning tool sharp, but can weaken the strength of the turning tool and can also make the heat dissipation condition worse, so the main back angle alpha is between 9 and 11 degrees;
the main deflection angle k gamma mainly affects the heat dissipation condition of the turning tool, the magnitude of the cutting component force, the change of the processing direction and the change of the cutting thickness. Theoretically, when a rubber mold with a 45-degree parting surface is machined, the machining requirement can be met by taking the main deflection angle kappa gamma of 45 degrees, and in order to avoid the influence of uncertain factors such as material resilience, machine tool precision and the like, the main deflection angle kappa gamma is taken to be 44.5 degrees;
the auxiliary deflection angle kappa ' gamma mainly reduces the friction between the auxiliary cutting edge and the machined surface of the workpiece, influences the surface machining quality of the workpiece and the strength of a turning tool, theoretically, when a rubber mold with a 45-degree parting surface is machined, the machining requirement can be met by taking the auxiliary deflection angle kappa ' gamma at 135 degrees, and in order to avoid the influence of uncertain factors such as material rebound and machine tool precision, the auxiliary deflection angle kappa ' gamma is taken at 135.5 degrees
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
