Described fly press, brake is installed on the entablature through support, and the piece of holding tightly of brake is looped around on the big belt wheel.

Described fly press, the top of interior cover and screw rod is provided with pressing plate, and pressing plate is fixedlyed connected with screw rod.

Described fly press, supporting mechanism comprises connecting plate, base and cover plate, wherein the connecting plate gap is sleeved on the screw rod and through clamp nut and is fixedly mounted on the entablature, the base gap is sleeved on the screw rod and is fixedly mounted on the connecting plate, the base and the screw coaxial heart, the lower end of overcoat is installed on the base through bearing, and the top of base is fixed with cover plate, and bearing is encapsulated in the cavity of cover plate, base and overcoat formation.

Described fly press, the flank profil of evagination straight-tooth is an involute, or circular arc line, interior cover and the evagination straight-tooth that puts outward are meshing with each other into line and contact and be slidingly matched; Motor adopts switched reluctance machines.

Its operation principle is: the output shaft of motor drives the overcoat that is supported on the supporting mechanism and rotates through small pulley, big belt wheel, overcoat is connected with interior cover spline, interior cover is connected through key with screw rod, screw pair transmission by screw rod and nut like this, make screw rod overlap the motion of spinning in reaching, and then the drive slide block is done rectilinear motion up and down.

The present invention compared with prior art, its advantage is:

1, because transmission mechanism is adopted splined interior cover and overcoat, and all be evenly equipped with the identical evagination straight-tooth of shape and quantity on the outer wall of interior cover, the inwall of overcoat, so interior cover is to have realized that through the evagination straight-tooth both lines contact with overcoat, frictional force is little, reduce frictional dissipation, prolonged service life of equipment.

2, motor drives overcoat through belt transmission structure and rotates torque increasing, rotating speed reduction, the effectively speed of service of adjusting slider.
