Abstract

The utility model discloses a double-edged straight flute sharp knife, which comprises a knife handle arranged at one end, a knife head arranged at the other end and a conical transition section arranged between the knife head and the knife handle, wherein two first chip grooves which are symmetrically arranged are arranged on the knife head and the transition section, and two second chip grooves which are symmetrically arranged and are respectively communicated with the first chip grooves are arranged on the knife handle; the machining effect is good, the service life is long, the cutter strength is high, the fracture-resistant machining material is formed in one step, and the machining time is saved; the combination of the straight line and the angle greatly shortens the processing time; the cutter saves secondary processing cost, saves time cost and labor cost of secondary processing, reduces the damage cost of materials and reduces the purchase cost of users.

Description

Double-edge straight flute sharp knife

Technical Field

The utility model relates to the technical field of machining, concretely relates to twolip straight flute sharp sword.

Background

A milling cutter is a rotating tool with one or more cutter teeth for milling. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine. However, in the using process of the traditional milling cutter, the milling cutter has poor processing effect on workpieces, short service life and long processing time.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a twolip straight flute sharp sword to prior art's weak point.

The utility model provides a technical scheme of above-mentioned problem does: a double-edge straight flute sharp knife comprises a knife handle arranged at one end, a knife head arranged at the other end and a conical transition section arranged between the knife head and the knife handle, wherein two first flute grooves which are symmetrically arranged are arranged on the knife head and the transition section, the first flute grooves are formed by two mutually vertical flute walls, the unilateral angle of the first flute grooves is 15 degrees, two second flute grooves which are symmetrically arranged and are respectively communicated with the first flute grooves are arranged on the knife handle, the second flute grooves are formed by two flute walls, one flute wall is a plane, and the other flute wall is a cambered surface;

the cutter head is divided by two first chip grooves to form two cutting edges, an end tooth angle is formed between the two cutting edges, and the end tooth angle is 150 degrees.

The utility model discloses beneficial effect has:

the utility model provides a double-edge straight flute sharp knife, which has good processing effect, long service life, high cutter strength, high breaking resistance, and one-step forming of processing materials, thereby saving the processing time; the combination of the straight line and the angle greatly shortens the processing time; the cutter saves secondary processing cost, saves time cost and labor cost of secondary processing, reduces the damage cost of materials and reduces the purchase cost of users.

fig. 2 is a front view of the present invention;

in the figure: 1-handle of a knife, 2-tool bit, 3-toper changeover portion, 4-first chip groove, 5-second chip groove, 6-cutting edge.

Detailed Description

The invention is further described with reference to the following drawings and detailed description.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

As shown in fig. 1, a double-edged straight flute sharp knife comprises a knife handle arranged at one end, a knife head arranged at the other end, and a conical transition section arranged between the knife head and the knife handle, wherein two first flute grooves which are symmetrically arranged are arranged on the knife head and the transition section, the first flute grooves are formed by two mutually perpendicular flute walls, the single-edge angle of the first flute grooves is 15 degrees, two second flute grooves which are symmetrically arranged and are respectively communicated with the first flute grooves are arranged on the knife handle, the second flute grooves are formed by two flute walls, one of the flute walls is a plane, and the other flute wall is an arc surface;

The utility model has good processing effect, long service life, high cutter strength and large fracture resistance, and saves processing time by one-step forming of processing materials; the combination of the straight line and the angle greatly shortens the processing time; the cutter saves secondary processing cost, saves time cost and labor cost of secondary processing, reduces the damage cost of materials and reduces the purchase cost of users.

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
