Abstract

The utility model relates to the technical field of hardware knives, in particular to an arc forming drill which comprises a knife handle and a knife head. Two forming edge portions are symmetrically arranged on the knife head, a V-shaped welding portion is arranged between the forming edge portions and the knife head, and a chip discharging groove is arranged between the forming edge portions. The arc forming drill is simple in structure, the V-shaped knife head is quick and convenient in welding, and a knife is higher in strength; processing of an inner hole arc surface can be completed at one step through the arc forming edge portions, so that production efficiency is higher; processing can be completed through a turning lathe and a milling machine, so that equipment investment of factories is lowered.

Description

A kind of moulding circular arc bores
Technical field
The utility model relates to hardware and cutting-tools technical field, and particularly a kind of moulding circular arc bores.
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.But for general processing factory, the kind quantity of lathe and the requirement of production cannot reach balance forever.Such as the man-hour that adds for bore circular arc face, normally can adopt numerically controlled lathe and hole boring cutter to process, first endoporus is carried out to bore hole roughing, and then pull out arc surface with the finish turning hole boring cutter track of moving in curves.This processing mode is not high to equipment requirement, but hole boring cutter easily occurs shake adding man-hour, makes machined surface occur Z-shaped lines, and cambered surface precision and working (machining) efficiency relatively low.Particularly the endoporus cambered surface in non-rotating plane needs machining center to process, and this cost for general machining factory is too high.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of compact conformation, the moulding circular arc that easy to use, working (machining) efficiency is high to bore.
For achieving the above object, the utility model is by the following technical solutions:
A kind of moulding circular arc described in the utility model bores, and comprises handle of a knife and cutter head, is arranged with two moulding blades on described cutter head, is provided with the weld part of V-arrangement between two moulding blades and cutter head, between two blades, is provided with chip area.
Further, the front end of described moulding blade is provided with two continuous arc milling swords.
Further, the arc length angle of described arc milling sword is less than 90 degree.
Further, described cutter head rear side is provided with shoulder.
The utility model beneficial effect is: the utility model is simple in structure, the cutter head welding of V-arrangement is efficient and convenient, cutter intensity is higher, once can complete the processing of bore circular arc face by two arc moulding blades, and production efficiency is higher, can complete by lathe and milling machine, reduce plant and equipment investment.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is moulding blade partial structurtes schematic diagram of the present utility model.
In figure:
1, handle of a knife; 2, cutter head; 3, moulding blade; 4, chip area;
21, weld part; 22, shoulder; 31, arc milling sword.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of moulding circular arc described in the utility model bores, and comprises handle of a knife 1 and cutter head 2, and described cutter head 2 rear sides are provided with shoulder 22, handle of a knife 1 clamping on chuck time shoulder 22 for the claw of conflicting with axial location, convenient installation; On cutter head 2, be arranged with two moulding blades 3, the front end of moulding blade 3 is provided with two continuous arc milling swords 31, and arc milling sword 31 can cutting at one time moulding, and machining accuracy and surface smoothness are good, effectively enhance productivity; The arc length angle of arc milling sword 31 is less than 90 degree, all has circular chamfering in the terminal of arc milling sword 31, and the intensity of moulding blade 3 is improved, and reduces the cutting abrasion speed of arc milling sword 31; Between two moulding blades 3 and cutter head 2, be provided with between 21, two blades of weld part of V-arrangement and be provided with chip area 4.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
