Abstract

The utility model relates to a T-shaped cutter for machining grooves with extremely low thicknesses. The T-shaped cutter for machining grooves with extremely low thicknesses comprises a cutter handle and a cutter bit; the diameter of the cutter handle is 12mm, which is different from common cutters with the handle diameters of 20mm; processing is ensured, and meanwhile bar materials are saved; the cutter handle and the cutter bit are connected by a conical body with a conical surface included angle of 11 degrees for playing roles of relieving a cutter and providing a sufficient cutting space for the cutter bit; a cutter bit column body is arranged between the cutter bit and the conical body and has the length of 13.25mm; the cutter bit has the thickness of 0.3mm, so that the T-shaped grooves with extremely small thicknesses can be machined conveniently; the upper and lower end surfaces are peripherally provided with chamfering blades respectively for the convenience of once molding; the smoothness of the machined surface is ensured; the machining limitation of traditional cutters is met; the machining precision and machining efficiency are improved; the production requirement is met.

Description

A kind of for processing the T-shaped cutter of very small thickness groove

Technical field

The utility model relates to a kind of for processing the T-shaped cutter of very small thickness groove, belongs to machine tools field.

Background technology

T-shaped cutter is processing T type groove, lateral grooves processing perfectly, at high temperature normally maintains cutting ability.At present, the T-shaped groove that carries out very small thickness adds man-hour, carries out disposable processing owing to lacking special cutter, and generally also needs to carry out manual grinding, so that cell body is smooth, has increased processing step, has also wasted manpower and materials, is difficult to ensure one-shot forming.

Utility model content

It is a kind of for processing the T-shaped cutter of very small thickness groove that the purpose of this utility model is to provide, and by cutter head thickness is set as to 3mm, meets the T-shaped groove processing of very small thickness, cutter head upper and lower end surface chamfer sword is made as to fillet chamfering simultaneously, ensures the fineness of machined surface.

For achieving the above object, the utility model provides a kind of and has comprised handle of a knife and cutter head for processing the T-shaped cutter of very small thickness groove, and the handle footpath of described handle of a knife is 12mm, is different from the cutter that general handle footpath is 20mm, ensures processing simultaneously, saving bar; Between described handle of a knife and cutter head, be connected with a bullet, the conical surface angle of described bullet is 11 °, plays cutter relieving effect, offers the enough cutting spaces of cutter head; Between described cutter head and bullet, be provided with cutter head cylinder, the length of described cutter head cylinder is 13.25mm; The thickness of described cutter head is 0.3mm, is convenient to the T-shaped groove processing of very small thickness, and upper and lower end face is circumferentially respectively equipped with chamfering blades, be convenient to one-shot forming, ensure the fineness of machined surface, meet the limitation of conventional tool processing, improve machining accuracy and working (machining) efficiency, met the needs of producing.

Further improvement of the utility model is: the chamfering of described chamfering blades is smooth fillet, and radius is 0.70mm, is the processing of the T-shaped groove fineness guarantee that provides good.

The beneficial effects of the utility model are: compact conformation, and easy to process, one-shot forming, cost-saving.

Brief description of the drawings

Fig. 1 represents front view of the present utility model;

Fig. 2 represents the A place enlarged drawing of the utility model Fig. 1;

Drawing reference numeral: 1-handle of a knife, 2-cutter head, 3-bullet, 4-cutter head cylinder.

Detailed description of the invention

In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail.

By reference to the accompanying drawings 1 with accompanying drawing 2, comprise handle of a knife 1 and cutter head 2, the handle footpath of described handle of a knife 1 is 12mm, with being squeezed into moulding mixture processing, is different from the cutter that general handle footpath is 20mm, ensures to process and saves bar simultaneously, can alleviate processing cost and process time.Between described handle of a knife 1 and cutter head 2, be connected with a bullet 3, the conical surface angle of described bullet 3 is 11 °, and bullet 3 provides the larger bit space that allows, and avoids handle of a knife 2 in working angles to touch workpiece; Between described cutter head 2 and bullet 3, be provided with cutter head cylinder 4, the length of described cutter head cylinder 4 is 13.25mm, ensures enough cutting outputs, meets the requirement of groove cutting; The thickness of described cutter head 2 is 0.3mm, and upper and lower end face is circumferentially respectively equipped with chamfering blades, and the chamfering of described chamfering blades is smooth fillet, and radius is 0.70mm.Be convenient to the T-shaped groove processing of very small thickness, be convenient to one-shot forming, ensure the fineness of machined surface, meet the limitation of conventional tool processing, improved machining accuracy and working (machining) efficiency, met the needs of producing.Greatly reduce cutter the destruction that adds the durability of man-hour to bar, ensure the service life of cutter.
