Abstract
The utility model belongs to the field of cutting tools and in particular relates to a split type chamfer forming cutter. The split type chamfer forming cutter comprises a cutter handle, a forming cutter head and a fastening piece, wherein a mounting base is arranged at the end part of the cutter handle, a coaxial connecting column is fixed on the end face of the mounting base, the diameter of the connecting column is smaller than that of the cutter handle, the diameter of the mounting base is larger than that of the cutter handle, at least one positioning pin is arranged on the end face of the mounting base, one through hole is formed in the axis part of the forming cutter head, the connecting column is inserted into the through hole, at least one positioning hole matched with the positioning pin is also formed in the end face of the forming cutter head, the positioning pin is inserted into the positioning hole, the fastening piece is sheathed into the connecting column to fasten the forming cutter head onto the side surface of the mounting base, and a chamfer oblique edge is formed on the peripheral surface of the forming cutter head. The split type chamfer forming cutter has the advantages that the forming cutter head can be positioned accurately by cooperation of the positioning pin and the positioning hole, and the chamfer oblique edge and an arc convex edge can be used for machining and forming a chamfer and an arc-shaped groove in one step, so that working efficiency is improved.
Description
Technical field
The utility model belongs to machining field of tool, particularly a kind of split type chamfering forming cutter.
Background technology
Chamfer machining is applicable to mould, mould bases chamfer machining, bed piece processing, and iron and steel processing, sheet metal chamfering, machinery equipment chamferings etc., are widely used in the industries such as iron and steel, steel construction, mould, metal processing, hardware manufacture; Milling cutter has a variety of, general milling cutter is integral type milling cutter, cutterhead and handle of a knife are integrated and process, need very thick material to process, production cost is higher, and while being damaged in cutterhead use procedure, cannot change, can only be that handle of a knife replaces together, use cost is very large like this, and its manufacturing cost makes many enterprises hang back on large basis more, and common milling cutter processing type groove also needs to carry out chamfer machining with chamfering utensil later, two procedures is numerous and diverse tediously long like this, wastes time and energy.
Summary of the invention
The utility model, for the weak point existing in above-mentioned technology, proposes the split type chamfering forming cutter of a kind of energy time processing moulding.
The utility model provides following technical scheme:
Split type chamfering forming cutter, it comprises handle of a knife, moulding cutterhead and securing member, handle of a knife end is provided with a mount pad, on mount pad end face, be fixed with coaxial joint pin, the diameter of joint pin is less than the diameter of handle of a knife, the diameter of mount pad is greater than the diameter of handle of a knife, on mount pad end face, be also provided with at least one alignment pin, moulding cutterhead axle center part is provided with a through hole, joint pin inserts in this through hole, on the end face of moulding cutterhead, be also provided with the locating hole that at least one coordinates with alignment pin, alignment pin inserts in locating hole, securing member is inserted in joint pin moulding cutterhead is fastened on to mount pad side, moulding cutterhead side face is provided with the oblique sword of chamfering.
The lateral surface of described moulding cutterhead is also provided with the protruding sword of circular arc.
The utility model has the advantages that to make same alignment pin and coordinating of locating hole moulding cutterhead location more accurate, the oblique sword of chamfering and the protruding sword energy of circular arc one-shot forming chamfering and arc groove, increase work efficiency simultaneously.
Accompanying drawing explanation
Fig. 1 is Split type structure schematic diagram of the present utility model.
