Description
Technical Field
The utility model relates to a turning cutter field, concretely relates to blade for turning.
Background
Turning is lathe machining, which is part of machining. Lathe machining mainly uses a lathe tool to perform turning machining on a rotating workpiece. The lathe can also be used for corresponding processing by using a drill bit, a reamer, a screw tap, a die, a knurling tool and the like. Lathes are used primarily for machining shafts, discs, sleeves and other workpieces having a surface of revolution, and are the most widely used type of machine tool in machine manufacturing and repair plants. The existing workpiece rotates, and a turning tool performs cutting processing of linear or curvilinear movement in a plane. Turning is generally performed on a lathe for machining an inner cylindrical surface, an outer cylindrical surface, an end surface, a conical surface, a forming surface, a thread, and the like of a workpiece.
Conventional turning inserts may be rotated forward to perform a cutting operation, but may not perform the cutting operation on the return stroke. If the cutting operation is performed during the return stroke, the cut surface after the cutting is finished cannot be guaranteed to be smooth. Therefore, the cutting operation needs to be carried out after the cutting operation is finished every time the cutting operation is carried out, so that the return time is wasted, and the improvement of the processing efficiency is not facilitated.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model aims at providing a higher blade for turning of machining efficiency.
In order to realize the technical purpose, the utility model discloses a scheme is: a blade for turning comprises a body, wherein three cutting parts are symmetrically arranged on the body, and a central hole is formed in the middle of the body;
the cutting part consists of a top plane, a first cutting edge, a first edge side surface, a second cutting edge, a second edge side surface and a cutter point arc, wherein the first cutting edge and the second cutting edge are positioned on two sides of the cutting part, a plurality of inclined columns are arranged between the top plane and the first cutting edge as well as between the top plane and the second cutting edge, a cutting accommodating groove is formed between the adjacent inclined columns, and the cutter point arc is positioned between the top of the first edge side surface and the top of the second edge side surface.
Preferably, a spherical bulge is further arranged between the top plane and the arc of the tool nose.
Preferably, the top plane is further provided with an inner concave surface.
Preferably, r of the tip arc is 0.8 ± 0.1 mm.
The cutting operation can be carried out on the blade in the process return stroke, the cutting efficiency is higher, the cutting effect is better, and the cutting efficiency can be greatly improved; meanwhile, the cutting tool is provided with inclined columns, and a cutting accommodating groove is formed between every two adjacent inclined columns; a spherical bulge is also arranged between the top plane and the arc of the tool nose.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the specific embodiment of the present invention is a blade for turning, which comprises a body 1, three cutting portions 2 are symmetrically disposed on the body 1, the front and back surfaces of the cutting portions 2 are symmetrical structures, and a central hole 3 is disposed in the middle of the body 1;
the cutting part 2 is composed of a top plane 201, a first cutting edge 202, a first edge side surface 203, a second cutting edge 204, a second edge side surface 205 and a nose arc 206, the first cutting edge 202 and the second cutting edge 204 are positioned at two sides of the cutting part 2, a plurality of inclined columns 207 are arranged between the top plane 201 and the first cutting edge 202 and the second cutting edge 204, a cutting accommodating groove 208 is arranged between the adjacent inclined columns 207, and the nose arc 206 is positioned between the top of the first edge side surface 203 and the top of the second edge side surface 205.
A spherical bulge 209 is also arranged between the top plane 201 and the arc 206 of the tool nose. The r of the nose arc 206 is 0.8 ± 0.1 mm.
The top plane 201 is also provided with an inner concave surface 210, and serial numbers can be engraved on the inner concave surface, so that the identification is convenient.
The first embodiment is as follows:
the thickness of the body is 4.8mm, the top end of the cutting part is of an R0.8mm arc structure, the mounting hole R3.68mm is formed in the center of the body, the distance from the gentle arc surface to the top end of the opposite cutting part is 12.17mm, and the distance from the top of the adjacent cutting part is 15.12 mm.
The cutting operation can be carried out on the blade in the process return stroke, the cutting efficiency is higher, the cutting effect is better, and the cutting efficiency can be greatly improved; meanwhile, the cutting tool is provided with inclined columns, and a cutting accommodating groove is formed between every two adjacent inclined columns; a spherical bulge is also arranged between the top plane and the arc of the tool nose.
The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
