Technical Field

The invention relates to die machining, in particular to a manual corner cleaning tool for a die.

Background

The die is mainly manufactured by a numerical control technology through numerical control machine tool machining. The mould that the numerical control was processed receives the effect of cutter radius, and some contained angles, corner places on the mould can form the fillet. The size of the fillet depends on the size of the radius of the cutter. The generation of the round corners is a phenomenon commonly existing in numerical control machining and is an inevitable negative result of the machining. The generation of the round corners changes the shape of the die, and on one hand, changes the shape of a product; on the other hand, the fit of the mold is affected. Therefore, after the numerical control machining of the die is completed, the machining residual round corners need to be removed, and the die is commonly called die corner cleaning in the die industry.

At present, the corner cleaning mode of the die mainly comprises two modes: one is the equipment corner cleaning, which is carried out by utilizing an electric spark technology; one is manual corner cleaning, which is performed manually by some tools. The electric spark corner cleaning can reduce the labor intensity and save the labor force; but the equipment cost is higher, the processing efficiency is lower, the electric spark corner cleaning cannot be applied to the large scale of the corner cleaning of the die, and more is mainly the manual corner cleaning. Manual corner cleaning is a good corner cleaning tool, and the manual efficiency can be effectively improved.

The chisel is a common tool for clearing the corner of the die. The common chisel for clearing the angle of the die is shown in figure 1, the chisel is a flat chisel A, the cutting edge B is flat, and the chisel belongs to a single-edge chisel. When the conventional flat chisel A is used for clearing corners of the die, the conventional flat chisel A needs to be repeatedly cleared along the two sides of the fillet D of the die C respectively to finally clear the fillet.

Although the chisel with the conventional structure can clear the residual round angle in the die machining process, in the process of clearing the angle, on one hand, the cutting edge of the chisel is of a sharp-angled structure and is easy to become blunt, the cutting edge needs to be frequently repaired, and the workload is increased; on the other hand, when the corners are cleaned, the corners need to be cleaned along the two sides of the round corner respectively, the labor intensity is high, and the efficiency is low.

Disclosure of Invention

The invention aims to solve the technical problem of the prior art, and aims to provide a mould manual corner cleaning tool capable of improving efficiency.

The technical scheme of the invention is as follows: a manual corner cleaning tool for a mold comprises a cutter body of a square column structure, wherein a first side face and a second side face which are adjacent to each other at the lower end of the cutter body are respectively provided with a first inclined face and a second inclined face, the first inclined face extends towards the inner side of the first side face in an inclined mode, the second inclined face extends towards the inner side of the second side face in an inclined mode, a first included angle between the first inclined face and the first side face is equal to a second included angle between the second inclined face and the second side face, the first inclined face and the second inclined face are intersected to form a guide blade, a third inclined face which extends towards the lower end of the guide blade is arranged at the bottom of the cutter body, the first inclined face and the third inclined face are intersected to form a first cutting blade, and the second inclined face and the third inclined face are intersected to.

As a further improvement, the first included angle and the second included angle are both 8-12 degrees.

Further, the inclination angle of the third inclined plane is 15-20 °.

Further, the periphery of the knife body is provided with a handheld part.

Further, the handheld portion comprises rounding portions respectively located on edges of the cutter body.

Furthermore, the surface of the rounding part is provided with an anti-slip layer.

Advantageous effects

Compared with the prior art, the invention has the advantages that: the guide blade, the first cutting blade and the second cutting blade form a three-dimensional cutting edge structure, so that the sharpness degree of the cutting edge can be reduced, the three-dimensional cutting edge is not easy to become blunt, the blade repairing frequency is reduced, and compared with the existing flat chisel, the service life of the flat chisel can be prolonged by more than three times; the three-dimensional cutting edge can realize simultaneous corner cleaning of two sides of a die fillet, and compared with the existing flat chisel, the corner cleaning efficiency can be improved by more than two times; the first inclined plane, the second inclined plane and the third inclined plane can realize free swing of the cutting edge of the chisel tool in the die corner cleaning process, so that a workpiece is not damaged, and the operation is convenient.
