Abstract
The utility model provides a clutch screw press. A return stroke actuating device is arranged on a machine frame of the screw press. The return stroke actuating device comprises a driving motor. The driving motor is connected with a pinion shaft through a second clutch. A pinion is arranged on the pinion shaft. A return stroke gear is arranged on a screw rod. The pinion meshes with the return stroke gear. The second clutch is connected with a second clutch controller. According to the clutch screw press, return stroke of a slide block is driven by the driving motor adopted by the clutch screw press, arrangement of a return stroke hydraulic cylinder is not needed, installed capacity of the driving motor is effectively reduced, the structure of the clutch screw press is simplified, and equipment cost is effectively reduced. Further, as the return stroke of a slide block is driven by the driving motor, the rotating angles of a rotor pair of the screw rod are needless to be enlarged, and therefore the transmission efficiency of the equipment is improved, and a relatively high rapping speed of the clutch screw press can be obtained in a relatively short period of time.
Description
Technical field
The utility model relates to a kind of fly press, particularly relates to a kind of clutch spiral press.
Background technology
Fly press be by driving screw rotarily drive the upper and lower motion of slide block, upwards realize backhaul, the forcing press that forges downwards.Fly press generally adopts screw rod, nut as transmission mechanism, and leans on worm drive to change the forward backward rotation motion of flywheel into slide block pump.When work, make flywheel accelerate rotation with stored energy by motor, promote slide block by screw rod, nut simultaneously and move downward, when slide block contact workpiece, flywheel is forced to slow down, and the rotation function of storage changes impact energy into, hit workpiece by slide block, make it distortion.
Existing fly press mainly has double plate friction fly press, electric screw press, three kinds of forms of clutch spiral press.The double plate friction press is combined flywheel driven by frictional disk and is rotated with flywheel, but because grinding disk exists larger friction to skid when flywheel is combined, so the mechanical kinetic energy loss is larger.Electric screw press is because the rotation of motor direct-drive flywheel, each operation cycle flywheel will be started from scratch and be accelerated to rated speed, after slide block hits finished piece(s), motor need counter-rotate slide block is promoted, therefore motor needs continually rotating starting, therefore this forcing press exist installed capacity large, electrical network is impacted large defective.
Clutch spiral press adopts clutch to connect flywheel and screw rod, flywheel passes to screw rod by clutch with kinetic energy, moved downward by screw rod band movable slider, when slide block with after workpiece contacts, the throw-out-of clutch controller will work when the rotating speed of flywheel is down to certain numerical value, back down hydraulic control valve by the control push rod and make throw-out-of clutch, and screw rod stops the rotation, flywheel continues rotation with storage power again along former direction, prepares to hit next time.This clutch spiral press in use, the motor that drives the flywheel rotation need not frequently forward and reverse rotation, it is more convenient therefore to use.But the back haul system of present this clutch spiral press all adopts in the front and back of frame or left and right sides installation backhaul hydraulic cylinder spurs the slide block backhaul, so just need to be equipped with the cumbersome hydraulic system of a cover to the backhaul hydraulic cylinder, and equipment cost is higher.And because hydraulic cylinder is vertically to spur slide block to go up, so must increase the helical angle of screw spiral pair, the transmission efficiency of end equipment will be fallen like this.
