Abstract

A shearing machine for machining the circular plate workpiece has a machine frame, a pair of upper and lowers disc-shaped shearing cutters rotating oppositely, a workpiece holder with the adjustable distance between it and shearing cutter and central boss for bearing workpiece, and a pressing screw bolt relative to said central boss for pressing the circular center of workpiece. When said workpiece is sheared by the pair of rotating shearing cutters, it is rotating with the disc-shaped shearing cutters, so obtaining a circular workpiece.

Description

Cuttig-off machine for working rounded tabulate pieces
Technical field
The present invention relates to a kind of shear with the circular flat part of revolving disk cutting processing.
Background technology
All need to process a large amount of circles or circular arc metal plate workpiece in all kinds of engineering constructions, adopt flame cutting or the die-cut method of punch press to process at present mostly.The former work efficiency is low, and quality is coarse; The latter only is suitable for processing that diameter is less, the workpiece of thinner thickness, and the big power consumption height of work noise.More existing shearing machines, they adopt a pair of revolving disk, and spiral guide plate are installed are processed circle or circular arc flat part, and this has improved production work efficiency and machining accuracy than the flame cutting, than the die-cut workpiece processing diameter range that enlarged of punch press.But need offhand to advance along camber line gradually when it is sheared, operation is trouble, and obviously work efficiency still owes high, and machining accuracy also is difficult to guarantee.
Summary of the invention
Purpose of the present invention provides a kind of simple in structurely, easy for operation, is particularly suitable for processing the high efficiency shearing machine of circle or circular arc flat panel workpieces.
Technical scheme of the present invention is: it comprises a pair of cooperation, the counterrotating circle shear cutting knife up and down that is installed on the frame, and be equipped with on the operating platform of circle shear cutting knife front can regulate and the circle shear cutting knife between the piece-holder seat of distance, piece-holder seat base is provided with the workpiece centre supporting boss, is equipped with at propping up of the workpiece center of circle in the middle part of the piece-holder seat is put the beams in place, with respect to the supporting boss on the base and presses screw rod.
The invention has the beneficial effects as follows, the supporting boss of its piece-holder seat is bearing in the central part of workpiece bottom, and a pressure screw rod props up and withstands the center of circle, plane on the workpiece, thereby in shear history, workpiece can be followed the shear knife tangential motion automatically, rotates the shearing of promptly finishing the round piece of certain radius a week.Easy and simple to handle, shear rate is fast, precision is high, quality is good; Processing cost is low; Complete machine structure is simple, reliable operation.
Description of drawings
Fig. 1 is a surface structure schematic diagram of the present invention.
Fig. 2 is the inner sectional structure schematic diagram of the present invention.
The specific embodiment
The invention will be further described with embodiment below in conjunction with accompanying drawing.
On frame 1 top, by rolling bearing units on the frame biside plate inwall 23,20 and rolling bearing units 24,18 circle shear slitter shaft 22 is installed flatly respectively and shears cutter shaft 25 with lower disc, circle shear slitter shaft 22,25 all runs through the frame biside plate up and down, the one side all is equipped with drive sprocket, and another side is separately installed with last circle shear cutting knife 4 and the lower disc shear knife 5 that mutual shearing cooperates.Frame 1 bottom is equipped with drive motors 26 and reduction box 14, and the sprocket wheel of chain 16 on the reduction gearbox output shaft 15, the sprocket wheel and the regulating wheel 17 of circle shear cutter shaft 22,25 ends carry out transmission up and down.On the slide rail 12 of the gantry operation platform 11 of circle shear cutting knife 4,5 fronts, long frame shape piece-holder seat 7 is installed, and the manipulation screw rod 9 of slippage grip slipper 7.Grip slipper 7 bottom frameworks middle part is provided with workpiece centre supporting boss 10, and grip slipper upper frame beam middle part, the band handle that is equipped with at workpiece 8 centers of circle with respect to the supporting boss on the bottom framework 10 prop up pressure screw rod 6.Be not offset for an accurate twelve Earthly Branches of tag of pressing screw rod 6 are pressed on the workpiece center of circle, also be fixed with screw rod end spacing collar 27 in grip slipper upper frame beam bottom surface.On the frame at circle shear cutting knife 4,5 back sides, be provided with the horizontal groove 13 of being convenient to workpiece 8 activities.Bearing in the rolling bearing units 20,18 of the slitter shaft of circle shear up and down 22,25 1 ends of present embodiment all adopts cone bearing, simultaneously being separately installed with the setscrew nut 21,19 that joins with bearing 20 medial surfaces and bearing 18 lateral surfaces on the cutter shaft up and down, to prevent cutter shaft axial displacement in the work.In addition, the bearing block top of the two ends rolling bearing units 23,20 of last circle shear slitter shaft 22 is connected with vertical adjusting screw 3,2, can regulate the horizontally disposed high and low position up and down of going up circle shear slitter shaft 22 easily, thereby make the circle shear cutting knife after disk diameter is dwindled in the blade wearing and tearing, can carry out mutual distance adjustment, cooperate with the shearing that continues to keep good.
