Abstract

The utility model belongs to machining and discloses a steel-plate inner hole machining knife which is mainly used for inner hole machining workpieces complex in machining procedure, overlarge in machining quantity, highly wasteful in raw material and needing repeated machining. The steel-plate inner hole machining knife comprises a knife rest and knife blades, and the knife blade is mounted on the knife rest. The steel-plate inner hole machining knife is characterized in that the knife rest is composed of a knife rest seat and two knife rest arms, the knife rest seat and the knife rest arms are integrally formed, cross section of each knife rest arm is arc-shaped, the knife blades are arranged on the end portions of the knife rest arms, concave faces of the knife rest arms are inward while convex faces of the same are outward, and the two concave faces are arranged oppositely. The steel-plate inner hole machining knife is simple in structure, and a piece inside a product can be directly taken out through a direct groove digging method, so that machining efficiency is improved, materials are saved, and the materials inside the product can be used for other purposes.

Description

Aperture knife tool in a kind of steel plate

Technical field:

The utility model belongs to machining, and the utility model is mainly used in steel plate processing endoporus, specifically establishes and the interior aperture knife tool of a kind of steel plate.

Background technology:

The processing of monorail crane roller inner holes is hang-up always, and monorail crane number of rollers is many, and manufacturing procedure is complicated, and hole surplus is large, is the drill bit with 50mm diameter in the past, hand-holing; Recycling lathe tool carries out 5 cuttings, reaches 76mm endoporus, then carries out finishing tool, reaches requirement 78mm endoporus.

In this process, workpiece manufacturing procedure is complicated, and processing capacity is excessive, reduces the service life of lathe and reduces precision, need to repeatedly process, and wastes a large amount of raw material, and workman's labour intensity is excessive, and safety coefficient is low.

Summary of the invention:

The purpose of this utility model is to provide a kind of solution because processing capacity is large, wastes a large amount of raw-material problems, and can improve precision, reduces labor strength, aperture knife tool in a kind of steel plate of enhancing productivity.

The utility model comprises knife rest, blade, and blade is arranged on knife rest, it is characterized in that knife rest is comprised of stand and two booms, stand and boom are integrated, and boom is that cross section is curved, and the end of boom is provided with blade, two boom concave surfaces are inside, and convex surface is outside, and two concave surfaces are oppositely arranged.

The utility model is with the cutter of annular cutting way machining hole on solid material.This tool sharpening can leave material core, can save material, reduces the power consumption of lathe; Not only improved working (machining) efficiency, and saved material, interiors of products material also can be used for other purposes.

The two ends of the utility model knife rest have 2 cutters tooth and carry out segmentation cutting, and incision is led, and is convenient to again reconditioning, manufacture; There is efficiency fast, the feature that cost is low;

Accompanying drawing explanation:

Fig. 1 is the front view of the utility model embodiment.

Fig. 2 is the upward view (Fig. 1 amplifies relatively) of Fig. 1.

In figure, 1, blade, 2, knife rest arm, 3, carriage saddle.

The specific embodiment:

Shown in Fig. 1, Fig. 2, the present embodiment is comprised of knife rest and blade, blade 1 is arranged on knife rest, it is characterized in that knife rest is comprised of carriage saddle 3 and two knife rest arms 2, carriage saddle 3 and two knife rest arms 2 are integrated, and knife rest arm 2 is that cross section is curved, the end of knife rest arm 2 is mounted by means of screws with blade 1, two knife rest arm 2 concave surfaces are inside, and convex surface is outside, and two concave surfaces are oppositely arranged.

The inwall radius of knife rest arm 2 is 29mm; Exterior radius is 38mm.Centre distance between two knife rest arms 2 is 58mm.
