Abstract
The utility model belongs to the technical field of the metal cutting tool, and particularly relates to a special cutting tool for a plain-end chamfering machine used for bevel cutting for steel tube orifices. The cutting tool comprises a cutter holder, a mechanically-clamped blade, a shim, a pressing plate and a fixing bolt, wherein, a threaded rod is arranged at the rear part of the cutter holder; the shim is fixedly installed at the front part of the cutter holder; the blade is installed on the shim; the pressing plate is installed on the blade; the blade is fixed on the shim through the fixing bolt and the pressing plate; and the blade cutting surface is fitted with the beveled edge or the port of the steel tube. The special cutting tool comprises an outer chamfering tool, an inner chamfering tool and a flat cutting tool; the shapes at the front parts of the three types of the cutting tools are different and radially installed on a cutter head; the positioning is reliable; the rigidity is good; the chipping allowance of the single tool is large; the vibration resistance is strong; the threaded rod arranged at the rear part of the cutter holder is used for positioning the cutting tool; therefore, the assistant adjustment time is saved, the operation is convenient and rapid, the precision is high, four knives can be installed on the cutter head to perform multitool cutting at the same time, the processing for the outer chamfer, the inner chamfer and the port of the steel pipe orifice are finished at one time, the chipping allowance is even, and the production efficiency is high.
Description
Technical field the utility model belongs to the metal-cutting machine tool technical field, specifically a kind of flat head chamfering machine dedicated tool that is used for steel pipe mouth of pipe chamfering machining.
Background technology steel pipe flat head chamfering machine is the process equipment of steel pipe's production enterprise indispensability, and function is that the steel pipe two ends is processed end surface shape and the groove that is fit to welding.The flat head chamfering rounding machine cutter of state, inside and outside manufacturer production adopts brazed shank tool or clamped cutting bit sheet usually, is generally the lathe tool form on the structure, and cutter becomes 90 ° of angles during installation with cutterhead, and rigidity is relatively poor; Adopt edge bearing during adjustment, complex operation needs often to measure and the reconditioning edge bearing.When adopting the multitool combination to cut, very easily damage cutter, so often adopt the hilted broadsword cutting way, cause flat head chamfering machine stock-removing efficiency low, seriously restricting the production efficiency of steel pipe.
The utility model content is adjusted inconvenience at existing flat head chamfering rounding machine cutter, the present situation that working (machining) efficiency is low, the purpose of this utility model provide a kind of easy and simple to handle, accurate positioning, in the time of effectively solving the steel pipe flat head chamfering cutter an adjustment difficult problem, improve the flat head chamfering machine dedicated tool of working (machining) efficiency.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: a kind of flat head chamfering machine dedicated tool, it is characterized in that: cutter comprises knife bar, clamped cutting bit sheet, edge bearing, pressing plate and set bolt, the knife bar rear portion is provided with threaded rod, the knife bar front portion installs edge bearing, adorn blade above the edge bearing, adorn pressing plate above the blade, set bolt and pressing plate are fixed on blade on the edge bearing, and the chamfering groove or the port of blade cut face and steel pipe fit.
The utility model has three kinds on outer chamfering tool, interior chamfering tool and planar end surface cutter, the knife bar front shape difference of three kinds of cutters, and three kinds of cutters are installed on the cutterhead; This cutterhead is submitted patent application separately to.Four unsteady tool rests are housed on the end face of cutterhead, install a cutter on each unsteady tool rest.According to the needs of institute's machined steel pipe end shape and wall thickness, on the cutterhead hard-wired four the configuration mode of cutter normally one outer chamfering tool, interior chamfering tool and two planar end surface cutters.Every knife bar according to the requirement of steel pipe groove, the indexable machine of a slice folder coated chip generally is installed, when the processing thick walled steel tube, outer chamfering knife bar can be installed two blades.The knife bar front shape is according to the decision of steel pipe end surface shape, and the threaded rod that the knife bar rear portion is provided with is used to adjust the knife bar position to the cutter positioning.Whole knife bar is packed into and is floated in the gathering sill on the tool rest, gets final product with locking nut locking after adjusting the knife bar position, does not need to fix with bridge screw in addition; When reality processing steel pipe, the utility model radially is installed on the cutterhead, and the location is reliable, good rigidly, the hilted broadsword chipping allowance is big, the vibration resistance height, the threaded rod that employing knife bar rear portion is provided with has been saved the auxiliary adjustment time to the cutter positioning, and is convenient to operation, the precision height can be installed four cuttves on the cutterhead, carry out multiple cut simultaneously, chipping allowance is even, once finishes the outer chamfering of the steel pipe mouth of pipe, interior chamfering and port processing, the working (machining) efficiency height, blade life is long, has effectively improved production efficiency; Efficiently solve the difficult problem that cutter is adjusted when having the steel pipe flat head chamfering now, courageously broken through the frame mode that traditional flat head chamfering machine knife bar adopts edge bearing to adjust.The utility model has been used for production practices.Just use at the big vertical masonry joint submerged arc of the UOE of Baoshan Iron ﹠ Steel Co., Ltd production line flat head chamfering machine at present, per hour can produce 30 steel pipes, annual production can reach 500,000 tons, and effect is very remarkable.
