Abstract

The utility model provides a multifunctional combined cutter with replaceable cutter heads used for the cutting operation of a planer, comprising a cutter holder (1), a cutter rack (2) and a series cutter heads (3) with different cutting functions. The cutter rack (2) is provided with a through hole, the cutter rack (2) is welded to one side of the lower part of the cutter rack (2), one cutter head (3) having a cross section fitting with the through hole is sheathed in the through hole and screwed by screws on the wall of the cutter rack (2). The utility model has the advantages of simple structure, easy production, high rate of finished products, raw material saving, convenient operation, etc.

Description

Multifunctional combined cutter

The utility model relates to a kind of gang tool that is used for machine tooling, particularly a kind of multifunctional combined cutter that is used for the interchangeable cutter head of planer machining.

Traditional planing tool is mostly at forger factory building processing and fabricating.Wherein: the structure of knife bar and cutter holder is an one, the general 45# of employing Fine Steel Casting iron round bar heats flat-die forging and forms, and blade extensively adopts W18Cr4V or Hardmetal materials, after forging slabbing, heated blade holder again forms with the sticking system of adhesives then.Its major defect is: 1) complex process, yield rate is low.In entire making process, if the bonding geometric angle of blade unreasonable, or reduced the hardness of blade, or the phenomenons such as insufficient strength of cutter holder, not waiting comes into operation has not scrapped once planing tool also.2) lack service life, waste is serious.A normal planing tool that uses, often through after the sharpening several times, blade has not just had use value, can only throw away together with knife bar.

The purpose of this utility model is to provide a kind of cutter head of can changing arbitrarily, and is simple in structure, is easy to make, and economizes in raw materials multifunctional combined cutter easy to use.

The purpose of this utility model is to realize like this, this multifunctional combined cutter is made up of knife bar, tool magazine and series of bits with different cutting functions, have a through hole in the tool magazine, tool magazine is welded on a side of knife bar below, be with the cutter head that its cross section and through hole match in the through hole, fasten by the screw threads on the tool magazine wall.

The utility model has following advantage owing to adopted fabricated structure: 1) simple in structure, be easy to make the yield rate height.2) because cutter head can be changed, when tool bit abrasion, only need to change cutter head and get final product, reduced unnecessary waste.3) owing to adopt series of bits, make operating personnel only need have a spot of cutter and the different cutter head of a series of cutting edge shape, just can deal with the requirement of complicated processing technology with different cutting functions, very easy to use.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a left view of the present utility model;

Fig. 3 is a vertical view of the present utility model;

Fig. 4 is the front view of another embodiment of the utility model;

Fig. 5 is the left view of Fig. 4;

Fig. 6 is the vertical view of Fig. 4.

As shown in Figure 1, 2, 3, the utility model is made up of knife bar (1), tool magazine (2) and the series of bits with different cutting functions (3), tool magazine (2) adopts the square pipe that has the square hole to make, tool magazine (2) vertically is welded on a side of knife bar (1) below, makes the axially consistent of through hole and knife bar (1) in the tool magazine (2).Be with its cross section in the through hole and be square and with the cutter head (3) that through hole matches, be tightened by the screw (4) on tool magazine (2) wall.

Shown in Fig. 4,5,6, tool magazine of the present utility model (2) also is to adopt the square pipe have the square hole to make, but and be transverse weld between the knife bar (1), make the axially perpendicular of through hole in the tool magazine (2) and knife bar (1).So that can carry out work with different angles after loading onto cutter head (3).

Knife bar of the present utility model both can adopt 45# Fine Steel Casting iron round bar, also can adopt the tailing of steel plate to make.Cutter head adopts the W18Cr4V material, by behind the mould forging molding a little sharpening can use, also can become various geometries by hot investment casting, cutter head also can adopt Hardmetal materials, so that satisfy the needs of complicated technology.
