Description

A kind of double-pole point lathe process cutter

Technical field

The utility model relates to machinery manufacturing technology field, is specially a kind of double-pole point lathe process cutter.

Background technology

Cutter occupies critical role in Machining Technology for Cutting, the main cutting edge of various cutter and the intersection area of front cutting edge just form the point of a knife of cutter, point of a knife position work under bad environment, thermal capacity is little, easy mill, damaged, be directly connected to machined surface quality again simultaneously, along with the development of Modern Manufacturing Technology, as the processing of various hard-cutting material, hard turning is processed, Precision Machining etc., cutter participate in the various piece of cutting, the proportion that point of a knife subparticipation is cut obviously increases, the impact of wearing and tearing on whole working angles of point of a knife part also increases thereupon, simultaneously, in working angles, nose part divide can not get effective lubrication also can the degree of enhance faster wear, reduction of service life.

Utility model content

The purpose of this utility model is to provide a kind of double-pole point lathe process cutter, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme: a kind of double-pole point lathe process cutter, comprise handle of a knife, cooling and lubricating passage, cutter tip, second point of a knife, linkage section, first point of a knife, exit orifice, cooling liquid inlet, second front cutting edge, second main cutting edge, first front cutting edge and the first main cutting edge, described first point of a knife and the second point of a knife lay respectively at the both sides of cutter tip, described first point of a knife is provided with the first main cutting edge and the first front cutting edge, described second point of a knife is provided with the second main cutting edge and the second front cutting edge, the linkage section be inwardly recessed is formed in the middle of described first point of a knife and the second point of a knife, the cooling and lubricating passage extended to handle of a knife is set between described first point of a knife and the second point of a knife, the cooling liquid inlet of described cooling and lubricating passage is positioned at the end of handle of a knife, the exit orifice of described cooling and lubricating passage is positioned on linkage section.

Preferably, described linkage section is fold-line-shaped linkage section.

Preferably, described cutter tip wraps up one deck nano nickel layer.

Preferably, described first point of a knife and the second point of a knife are circular arc.

Preferably, the distance between described first point of a knife and two arc cores of the second point of a knife is 1mm ~ 30mm.

Compared with prior art, the beneficial effects of the utility model are: this double-pole point lathe process cutter structure is simple, reasonable in design, the setting of double-pole point adds cutting-tool's used life, the setting of cooling and lubricating passage makes lubrication directly act on two points of a knife, is more conducive to extending cutting-tool's used life.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is the partial enlarged drawing of in Fig. 13.

In figure: 1, handle of a knife, 2, cooling and lubricating passage, 3, cutter tip, the 4, second point of a knife, 5, linkage section, the 6, first point of a knife, 7, exit orifice, 8, cooling liquid inlet, 9, the second front cutting edge, the 10, second main cutting edge, the 11, first front cutting edge, the 12, first main cutting edge.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1-2, the utility model provides a kind of technical scheme: a kind of double-pole point lathe process cutter, comprise handle of a knife 1, cooling and lubricating passage 2, cutter tip 3, second point of a knife 4, linkage section 5, first point of a knife 6, exit orifice 7, cooling liquid inlet 8, second front cutting edge 9, second main cutting edge 10, first front cutting edge 11 and the first main cutting edge 12, first point of a knife 6 and the second point of a knife 4 lay respectively at the both sides of cutter tip 3, cutter tip 3 wraps up one deck nano nickel layer, first point of a knife 6 and the second point of a knife 4 are circular arc, distance between first point of a knife 6 and two arc cores of the second point of a knife 4 is 1mm ~ 30mm, first point of a knife 6 is provided with the first main cutting edge 12 and the first front cutting edge 11, second point of a knife 4 is provided with the second main cutting edge 10 and the second front cutting edge 9, the linkage section 5 be inwardly recessed is formed in the middle of first point of a knife 6 and the second point of a knife 4, the cooling and lubricating passage 2 extended to handle of a knife 1 is set between first point of a knife 6 and the second point of a knife 4, the cooling liquid inlet 8 of cooling and lubricating passage 2 is positioned at the end of handle of a knife 1, the exit orifice 7 of cooling and lubricating passage 2 is positioned on linkage section 5, linkage section 5 is fold-line-shaped linkage section.

Its operation principle: in use, carries out clamping by cutter, and the first point of a knife 6 or the second point of a knife 4 can be selected very easily to carry out work, work while, also can cool with cooling and lubricating passage 2 pairs of cutters, make work efficiency greatly improve.
