Abstract

The invention relates to the technical field of metal cutters, in particular to a tungsten-steel welding spade drill. The tungsten-steel welding spade drill comprises a cutter shank and a cutter carrier which are integrally arranged. A spade drill body and two tungsten-steel blades are arranged at the front end of the cutter carrier. The tungsten-steel blades are welded with the cutter carrier by taking the spade drill body as the center. The tungsten-steel blades and the spade drill body are arranged at intervals. The tungsten-steel welding spade drill is simple in structure; through matching of the spade drill body and the welded tungsten-steel blades, two cutting edges of the spade drill body drill stepped inner holes of workpieces, and the tungsten-steel blades process the outer edges and the end faces of the workpieces, so that processing efficiency is improved through one-time turning, and production cost is reduced.

Description

A kind of wolfram steel welding chit drill
Technical field
The present invention relates to hardware and cutting-tools technical field, particularly a kind of wolfram steel welding chit drill.
Background technology
Machining generally comprises car, plane, milling, brill, mill etc., various processing modes all have different processing technologys and special cutter, wherein common hardware and cutting-tools comprises lathe tool, milling cutter, planing tool, fluted drill etc., to meet different products and processing request.For the interior outer rim of product, process general first car outer rim at present, and need to pass through the multiple working procedures such as punching, bore hole, chamfering to endoporus, wherein need to change multiple cutter, the cost of charp tool is higher and production efficiency is very low.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, provide a kind of compact conformation, wolfram steel easy to use to weld chit drill.
For achieving the above object, the present invention is by the following technical solutions:
A kind of wolfram steel welding chit drill of the present invention, comprises the handle of a knife and the knife rest that are wholely set, and described knife rest front end is provided with spade drill and two tungsten steel blades, two tungsten steel blades centered by spade drill with knife rest welding, tungsten steel blade and the setting of spade drill interval.
Further, described spade drill is provided with the first rank sword and second-order sword, between the first rank sword and second-order sword, is provided with chamfering blades.
Further, the outside of described tungsten steel blade is provided with outer rim sword, and tungsten steel blade bottom is provided with shear blade, and tungsten steel blade inboard is provided with inner edge sword.
Further, the connecting portion between described tungsten steel blade and spade drill is provided with end face transitional edges.
Beneficial effect of the present invention is: the present invention is simple in structure, by spade drill, coordinate with the tungsten steel blade of welding, two blades of spade drill are to workpiece turning inner bore of step, and outer rim and the end face of tungsten steel blade to workpiece processed, a turning improves working (machining) efficiency, reduces production costs.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
In figure:
1, handle of a knife; 2, knife rest; 3, spade drill; 4, tungsten steel blade;
31, the first rank sword; 32, second-order sword; 33, chamfering blades; 34, transitional edges;
41, outer rim sword; 42, shear blade; 43, inner edge sword.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of wolfram steel welding chit drill of the present invention, comprise the handle of a knife 1 and the knife rest 2 that are wholely set, described knife rest 2 front ends are provided with spade drill 3 and two tungsten steel blades 4, two tungsten steel blades 4 weld with knife rest 2 centered by spade drill 3, tungsten steel blade 4 arranges with spade drill 3 intervals, tungsten steel blade 4 and spade drill 3 turning processing endoporus and outer rim respectively; Spade drill 3 is provided with between the first rank sword 31 and second-order sword 32, the first rank swords 31 and second-order sword 32 and is provided with chamfering blades 33, and spade drill 3 passes through the first rank sword 31 and second-order sword 32 turning stepped holes, and passes through chamfering blades 33 to step chamfering; The outside of tungsten steel blade 4 is provided with outer rim sword 41, and tungsten steel blade 4 bottoms are provided with shear blade 42, and tungsten steel blade 4 inboards are provided with inner edge sword 43; Connecting portion between tungsten steel blade 4 and spade drill 3 is provided with end face transitional edges 34; The present invention once completes interior outer rim turning, can reduce the kind of cutter, enhances productivity and reduces production costs.
The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
