Description

Spiral rake angle rectangular spline broach

Technical Field

The utility model relates to the technical field of metal cutting tools, in particular to a spiral rake angle rectangular spline broach.

Background

The high-speed cutting tool refers to a tool for cutting and processing of a numerical control machine tool under the condition of high-speed running operation, and is suitable for various machine tools, such as hard alloy, coated tools, cermets, ceramics, cubic boron nitride and diamond tools. They have the advantage of being suitable for different workpiece materials and different cutting speed ranges. It must be noted that there is a problem of suitability between the tool material and the pair of workpiece materials, i.e. that one tool material performs well with the workpiece material, but not perfectly when processing the other workpiece material, in other words, there is no universal tool material which can be used for high speed processing of all workpiece materials.

Disclosure of utility model

The utility model aims to solve the technical problems that: the existing spiral rake angle rectangular spline broach has no effective guarantee on connection efficiency and connection stability when working, and the fixing effect and the fixing step of the broach body are not simplified enough in the use process, so that the fixing effect and the fixing stability of the device are affected to a certain extent.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a spiral rake angle rectangular spline broach, includes the cutter body, the top fixedly connected with back handle of cutter body, the top of back handle is run through there is first hexagon screw, the bottom fixedly connected with front handle of cutter body, the bottom of front handle is run through there is the second hexagon screw.

As a preferable scheme, the cutter body is connected with the rear handle through a first hexagonal screw, and the cutter body is connected with the front handle through a second hexagonal screw.

As an optimal scheme, the specifications of the first hexagon screw and the second hexagon screw are M6 hexagon socket screws, and meanwhile, the first hexagon screw and the second hexagon screw are provided with spring washers.

As a preferable scheme, the cutter body comprises a cutter ring positioned at the top of the front handle, the outer wall of the cutter ring is fixedly connected with a rear guide key, and the width of the rear guide key is 4.72mm.

As a preferable scheme, the outer wall of the cutter body is provided with a spiral chip flute, the spiral direction of the spiral chip flute is rightward, and the lead of the spiral chip flute is 18.

As a preferable scheme, the cutter body is made of high-speed steel, the cutter body is 1170mm in length, the front handle is 230mm in length, and the rear handle is 170mm in length.

The beneficial effects of the utility model are as follows: can effectually install fixedly through first hexagon screw and second hexagon screw to preceding handle and back handle when using, let installation effectiveness have promotion by a wide margin when using, can effectually carry out the condition of cutting the residue discharge through spiral chip flute simultaneously when using, let cut efficiency and stability all effectual promotion.
