Abstract
The utility model relates to a spinning machine for machining the paraboloid. The utility model is characterized in that a paraboloidal convex die is arranged on a main shaft driven by a motor, a top die is arranged on a tail frame, the back part of a machine frame is provided with a screw rod and slide plate mechanism, an air-operated spinning mechanism composed of a spinning wheel, a piston and an air cylinder, a guide wheel and an edge unfolding wheel, a workpiece held on the paraboloidal convex die rotates along with the main shaft, the spinning wheel is driven by the screw rod and the slide plate to move outward, the workpiece is pressed by the spinning wheel under the action of the air-operated spinning mechanism, and the workpiece is forced to make an extension and a plastic deformation along the paraboloidal convex die. The utility model has the advantages of simple structure, reduced paraboloidal manufacturing cost, increased quality and efficiency.
Description
A kind of special purpose machine tool of processing parabolic usefulness.
Parabola is widely used in fields such as radar, solar cooker, satellite television receiving antenna.At present, process paraboloidal lathe and be generally punch press or large hydraulic press.Punch press can only stamp out paraboloidal valvula, also needs valvula assembly unit moulding, so complex manufacturing, production efficiency is low and the product precision is not high.Though large hydraulic press can make parabolic once molding formed, boost productivity and product quality,, large hydraulic press and mould thereof will expend a large amount of investments, and parabolic production cost is greatly improved.
The purpose of this utility model provides a kind of parabolic processing machine of exerting pressure, and accomplishes simple in structurely, can reduce paraboloidal production cost, improves product quality and production efficiency.
The purpose of this utility model is achieved in that on by the main shaft of driven by motor installs parabolic punch, the pneumatic spinning machine of backform, frame rear portion installation screw mandrel sled mechanism being installed on the tailstock and constituting, and directive wheel and side wheel by spinning wheel, piston, cylinder.When clamping workpiece withstands on parabolic punch and with backform, main shaft drives the workpiece rotation, spinning wheel is under the drive of screw mandrel, outwards move on the one hand, under the effect of pneumatic spinning machine, workpiece is exerted pressure on the other hand, force workpiece along parabolic punch generation extension and plastic deformation and form parabola.
Fig. 1 is parabolic rotary pressure machine structure schematic diagram.
Describe concrete structure of the present utility model and operation principle in detail below in conjunction with Fig. 1 and embodiment.
As shown in Figure 1, main spindle box 2 is installed in frame 1 front end that is welded with shaped steel, bearing 3 and main shaft 4 are housed in the case, main shaft 4 left ends and motor 5 usefulness V belts link, it is characterized in that main shaft 4 right-hand members are equipped with parabolic punch 6, backform 11 is installed on the frame 1 rear end tailstock, the axle center of backform 11 and main shaft 4 are on same center line, leading screw 14 and guide rail 15 two ends that are made of two hollow cylinders connect with supporting base 12 and are fixed on the frame 1, and the slide plate 13 that is enclosed within on the leading screw 14 is installed in above the guide rail 15.Rotational lead screw 14, slide plate 13 can be along guide rail 15 back and forth movements.The pneumatic spinning machine that is made of spinning wheel 7, piston rod 8, piston 9, cylinder 10 is equipped with on slide plate 13 tops.Spinning wheel 7 was both rotatable, can make reciprocal feed motion again.Directive wheel 16 is installed in guide rail 15 rearward end, and buncher 18 is installed in frame 1 bottom, and it connects with screw mandrel 14 usefulness sprocket wheels, chain; Side wheel 17 is installed on the bearing near the frame 1 at parabolic punch 6 edges, and the center of side wheel 17 and parabolic punch 6 coexists on the horizontal plane.
Operation principle of the present utility model is: garden shape sheet material is compressed by backform 11, parabolic punch 6 is close in the centre, under motor 5 drives, main shaft 4, punch 6, backform 11 and workpiece be rotation synchronously just, when cylinder 10 right chambeies enter compressed air, promote piston 9, piston rod 8 and spinning wheel 7 advance, spinning wheel 7 workpiece pressings, under driving, frictional force together rotates with workpiece, under the spinning effect, workpiece is extended, produce plastic deformation, start buncher 18, sprocket wheel, 14 rotations of chain drive screw mandrel, screw mandrel 14 drives slide plate 13, cylinder 10, spinning wheel 7 is made feed motion along guide rail 15, like this feeding of limit spinning limit, make workpiece be close to punch 6, parabola forms therefrom.
The utility model operational procedure is as follows: at first garden shape sheet material is packed on the parabolic punch 6, tighten backform 11, with slide plate 13, spinning wheel 7 rests in the position of backform 11, starter motor 5 makes the rotation of main shaft 4 and punch 6 and workpiece, opens pneumatic operated valve, compressed air enters cylinder 10 right chambeies, promotes spinning wheel 7 work, starts buncher 18, drive screw mandrel 14 rotations, slide plate 13 and spinning wheel 7 are made feed motion, and operational guidance wheel 16 forces workpiece towards punch 6 direction moulding, be depressed into the proper time of the edge of work when spinning wheel 7, close buncher 18, slide plate 13 stop motions, operation side wheel 17, workpiece is turned over stiffened edge, then, disable motor 5, main shaft 4 stops operating, handle reversal valve, cylinder 10 left chamber air inlets, the exhaust of right chamber, spinning wheel 7 is given up the throne, unscrew backform 11, unload workpiece.
Compared with the prior art, the utility model is simple in structure, and low equipment investment can be simplified paraboloidal production technology, enhances productivity, and reduces production costs and improves the quality of products.
