Description

Be used to remove the broaching tool of edges of plate material burr

Technical field

The utility model relates to a kind of broaching tool, especially a kind of broaching tool that is used to remove the edges of plate material burr.

Background technology

Plate shearing machine and lath cutter usually exist a lot of seamed edge wedge angles, burr after sheet materials such as steel plate are cut off on section.These wedge angles and burr are easy to the surface tear with other workpiece, or the staff is scratched.Therefore, behind sheet shearing, generally all can have remove burr, with the operation of wedge angle abate, sharp-pointed seamed edge is carried out abate handles and make seamed edge become slightly blunt, to avoid scratching other workpiece or staff.In prior art, remove the method that burr generally all adopts instrument polishings such as file, angle emery wheel, blinds wheel, sand paper, when using these methods to handle, the burr easy flanging, the burr after the processing or the position of wedge angle are more coarse, always make the people feel that burr is untreated totally when touching with hand, and the staff generally can polish with fine sandpaper once more, to obtain good smoothness, this processing method has to waste time and energy, need problems such as configuration milling tools, inefficiency.

The utility model content

The utility model is the weak point that exists in the above-mentioned prior art for avoiding, a kind of broaching tool that is used to remove the edges of plate material burr is provided, increasing work efficiency, and remove burr and wedge angle quickly and easily, obtain good smoothness at the seamed edge place of sheet material simultaneously.

The utility model be the technical solution problem by the following technical solutions.

Be used to remove the broaching tool of edges of plate material burr, it is characterized in that cutter head and blade are integral structure, cutter head one side has " √ " shape edge of a knife, and the bending place of " √ " shape is a circular arc in " √ " shape edge of a knife, and knife-edge is a blade.

The design feature that the utility model is used to remove the broaching tool of edges of plate material burr also is:

The top of described cutter head is semicircle.

Described blade is a rectangle, and the angle on the blade border line at the place, long limit of " √ " shape of " √ " shape edge of a knife and the long limit of described rectangle blade is α, wherein 15 °≤α≤30 °.

Angle between the blade border line at the blade border line at the place, long limit of " √ " shape of described " √ " shape edge of a knife and the minor face place of " √ " shape is β, wherein 35 °≤β≤45 °.

Broaching tool of the present utility model can process with useless saw blade, and the sawtooth of saw blade is polished, and termination portion reconditioning becomes semicircle, and the side grinding at cutter head goes out " √ " shape edge of a knife then, and grinds blade at knife-edge part." √ " shape edge of a knife is the V-arrangement edge of a knife, but V-arrangement is also asymmetric, varying in size of two length of sides of V-arrangement, minor face is positioned at the side near the cutter head top, long limit is positioned at the side near blade, the part that long limit and minor face intersect is the bending place, and the bending place is a circular arc, and therefore whole edge of a knife shape is " √ " shape.During use, the edge of a knife is attached on the seamed edge that need to remove burr or wedge angle,, makes blade slip over, can remove burr or, and can make the good smoothness of seamed edge maintenance the wedge angle abate from seamed edge with pulling the moving knife body.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, convenient to use, time saving and energy saving.Particularly for all burrs of non-ferrous metal plate, be used for hacksaw blade because non-ferrous metal plate intensity is low, the broaching tool hardness that hacksaw blade is worn into is enough to satisfy split requirement.

2, improve the removal quality of burr, can obtain good smoothness.The seamed edge of length of side 500mm under the normal condition only needs a cutter from the beginning to move at the end, can be with the seamed edge abate, and the deburring the trailing edge is circular-arc, is smooth to the touch.

3, cost is low.Broaching tool of the present utility model adopts waste and old saw blade reconditioning to form, and belongs to the utilization once more of refuse.And existing method need be used file, angle grinding wheel, sand paper etc., and a sand paper needs about monobasic, a portable grinding wheel, and hundred impeller blades need about 1.50 yuan, and comparatively speaking, the utility model is almost without any need for material cost.

4, improved operating efficiency.Remove the burr of the aluminium sheet periphery of a 500mm * 500mm * 6mm to have method now, go 8 seamed edges to need 5 minutes at least, and use broaching tool of the present utility model to finish same work, only needed to finish in 0.5 minute.

The utility model adopts discarded saw blade, can be made into through simple processing, seamed edge smoothness after the processing is good, have the operating efficiency that can improve deburring or seamed edge abate, time saving and energy saving, simple to operate and convenient and swift, cost is low and advantage such as easy realization.

The utility model is particularly useful for the burr of steel plate seamed edge to be removed or the seamed edge abate, and the burr that also can be used for other hard plate material seamed edges is removed or the seamed edge abate.

Description of drawings

The schematic diagram of Fig. 1 broaching tool of the present utility model.

Fig. 2 is the B-B cutaway view among Fig. 1.

Label in accompanying drawing 1, the accompanying drawing 2: 1 cutter head, 11 tops, 2 blades, 21 long limits, 3 edges of a knife, 31 bending places, 32 blades, 321 blade border lines, 322 blade border lines.
