Abstract
A multi-angle large flat-end chamfering machine cutter comprises a cutter plate, flat end face cutters, inner chamfering cutters and multi-angle cutters are symmetrically installed on the knife plate, and a pair of multi-angle cutters are installed on the cutter plate symmetrically. Each multi-angle cutter is composed of a cutter bar, a blade, a gasket, a platen and platen screws, wherein the cutter bar is installed on the cutter plate, the gasket, the blade and the platen are sequentially installed in a groove of the front end of the cutter bar from inside to outside, the front end of the platen is pressed on the surface of the blade, and the rear end of the platen is fixed on the cutter bar through the screws. Compared with the prior art, the multi-angle large flat-end chamfering machine cutter has the advantages that a blade with multiple angles is achieved on the flat-head chamfering machine, the quality of cleavage surface after machining is good, the changing and the adjustment of cutters are convenient and fast, the machine runs stably, the manufacturing efficiency is high, the multi-angle chamfering requirements of large-wall-thickness steel pipes with the wall thickness larger than 22mm are met, and the cutter is reasonable in design, simple, practical, safe to operate and convenient to use.
Description
Technical field
The invention belongs to the Steel pipe end surface process equipment, relate in particular to the End-facing/chamfering Machine For Steel Tubes cutter, be specially adapted to the cutter of large wall thickness steel tube plain-end chamfering machine.
Background technology
In prior art, Steel Tube Industry mostly carries out flat head chamfering to pipe end, and the bevel angle of chamfered edge is generally 30.5 °, 37.5 °, 45 etc.The cutter of existing plain-end chamfering machine is single bevel angle, and the deficiency of existing plain-end chamfering machine is:
1, single bevel angle, cutting power is large; The metal that need to fill during butt welding between steel pipe increases, and production efficiency is low;
If 2 adopt lathe processing multi-angle groove, production efficiency is extremely low;
If 3 adopt gang tool processing multi-angle groove on plain-end chamfering machine, the groove face poor quality, can not meet the demands, and cutter is adjusted complicated.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of multi-angle large-scale flat head chamfering rounding machine cutter, complete flat head chamfering and the beveling of pipe end on large-scale plain-end chamfering machine.
the objective of the invention is to adopt following technical scheme to realize: the large-scale flat head chamfering rounding machine cutter of multi-angle, comprise cutterhead, be symmetrically installed with planar end surface cutter and interior rose reamer on cutterhead, it is characterized in that the large-scale flat head chamfering rounding machine cutter of described multi-angle also comprises the multi-angle cutter, one-to-many angular cutter symmetry is arranged on cutterhead, described multi-angle cutter is by knife bar, blade, pad, pressing plate and bridge screw form, knife bar is arranged on cutterhead, pad is installed in the groove of knife bar front end from the inside to the outside successively, blade and pressing plate, the pressing plate front end is pressed in blade face, the rear end is fixed on knife bar by bridge screw.
The large-scale flat head chamfering rounding machine cutter of multi-angle of the present invention, the anterior angle α that it is characterized in that described blade is 8 °; Relief angle β is 7 °; Cutting edge inclination θ is 4 °, and the cutting edge angle γ of blade selects according to user's needs.
The large-scale flat head chamfering rounding machine cutter of multi-angle of the present invention is characterized in that the length L=70mm of described blade, and blade is rhombus.
The course of work of the present invention is as follows:
Rose reamer at least one cover multi-angle cutter of installing, a cover planar end surface cutter, a cover on the cutterhead of plain-end chamfering machine, adjust the tool position, set feed speed, cutting speed, then the cutterhead swivel feeding cuts fixed pipe end, after completing cutwork, cutterhead is return original position.
Compared with prior art the invention has the beneficial effects as follows: realized that on plain-end chamfering machine a blade has a plurality of angles, after processing, the groove face quality is good; Cutter changing and quick, machine easy to adjust operate steadily, and production efficiency is high, satisfies wall thickness greater than the multi-angle chamfered edge requirement of 22mm large wall thickness steel tube; Reasonable in design, simple and practical, handling safety, easy to use.
