Abstract
The utility model relates to the technical field of a hardware cutter, in particular to a tungsten steel welding flat drill, which comprises a cutter handle and a cutter frame in integral arrangement, wherein the front end of the cutter frame is provided with a flat drill and two tungsten steel cutter blades, the two tungsten steel cutter blades use the flat drill as the center to be welded with the cutter frame, and the tungsten steel cutter blades and the flat drill are in separated arrangement. The tungsten steel welding flat drill has the advantages that the structure is simple, through the matching between the flat drill and the welded tungsten steel cutter blades, the two cutting edges of the flat drill carry out step inner hole turning on a workpiece, the tungsten steel cutter blades are used for processing the outer edge and the end surface of the workpiece, the one-step turning is realized, the processing efficiency is improved, and the production cost is reduced.
Description
Technical field
The utility model 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.Process general first car outer rim for the interior outer rim of product 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.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of compact conformation, wolfram steel easy to use to weld chit drill.
For achieving the above object, the utility model is by the following technical solutions:
A kind of wolfram steel welding chit drill described in the utility model, 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.
The utility model beneficial effect is: the utility model is simple in structure, coordinate with the tungsten steel blade of welding by spade drill, 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
