Description
Technical field
The invention provides a kind of spline-transmission screw press, belong to field of mechanical industrial equipment.
Background technology
Existing two frictional disk fly presses are owing to adopting frictional drive, driven by motor two frictional disks High Rotation Speed all the time, and gear wheel needs to change direction of rotation in each circulation, during commutation, gear wheel and frictional disk can produce serious skidding, not only consume energy, reduce transmission efficiency, also exacerbate the wearing and tearing of friction belt; Because frictional drive exists skidding, be unfavorable for the accurate control of strike process, can not automation be realized.In the recent period, invent many patents for fly press, but lack the large-scale spiral press technologies that cost is low, reliability is high, easily manufactured.
Summary of the invention
The object of the invention is to provide for current the spline-transmission screw press that a kind of cost is low, reliability is high, easily manufactured.
Its technical scheme is:
A kind of spline-transmission screw press, comprise fuselage, the nut on fuselage is fixedly mounted on through nut pressing plate, the screw rod be connected with nut thread, disc, bearing block, support set, bearing plate, spline overcoat, spline inner sleeve, screw rod pressing plate, gear wheel and symmetrical 2 motors being arranged on fuselage both sides, wherein disc is sleeved on nut pressing plate, and lower surface is fixedly connected with the upper surface of fuselage, the bearing sleeve being provided with thrust bearing and rolling bearing is contained on screw rod, bottom is fixedly connected with disc upper surface, support set is provided with between thrust bearing and rolling bearing, bearing plate is fixed on the upper surface of bearing block, spline coat suit is on screw rod and by thrust bearing and rolling bearing location, spline inner sleeve is fixedly mounted on the upper end of screw rod through screw rod pressing plate, and the outer wall of spline inner sleeve and the inwall of spline overcoat are all evenly equipped with shape and the identical spline tooth of quantity, gear wheel is fixedly set on the flange of spline overcoat, it is characterized in that: gear wheel (12) is embedded with spline, the recessed footpath of spline inner sleeve is
the convex footpath of spline inner sleeve is D>=1.1d, and in formula, k is conversion factor, σ
bfor the tensile strength of material, F is the hitting power of forcing press, r
cfor the central diameter of screw rod, ρ is spiral friction angle, and α is the lift angle of screw rod.
Its operation principle: the direct meshing gear wheel of pinion of two motor shaft ends, drives gear wheel to rotate.The spline joint Direct driver bolt rotary that the gear wheel rotated is formed by spline overcoat and the spline inner sleeve at center, because spline inner sleeve is fixed on screw rod, along with motor positive and inverse moves, spline inner sleeve moves up and down at spline jacket internal along with while screw rod rotation.When motor rotates forward, screw rod rotates descending, and band movable slider hits workpiece, and shaping rear motor reverses, and screw rod reverses up, and is parked in top dead centre, completes a working cycles.
Compared with prior art, its advantage is in the present invention:
1, gear spline drving sprial forcing press, two motor symmetries are arranged on fuselage both sides, avoid the lateral shift power that single motor driven belts is come, moment of flexure suffered by screw rod is made to be zero, extend the service life of screw rod, and Dual-motors Driving, motor by the pinion of motor shaft end and gear wheel directly meshing, more steady compared with frictional drive, reliably.
2, spline overcoat is arranged in bearing block, and spline inner sleeve and screw rod are positioned at spline overcoat, and structure is closed, compact, is convenient to lubrication, and dismounting and maintenance, easily manufactured, cost is low.
3, the frictional drive of double disk friction screw press is replaced by motor direct-drive gear wheel, the highly energy-consuming phenomenon of the motor eliminating double disk friction screw press High Rotation Speed always.
4, use the mode of spline drived to drive screw rod, make this forcing press can be realized the accurate setting of strike process by the mode of motor numerical control, drastically increase product quality.
5, the calculating in the recessed footpath of spline inner sleeve, convex footpath makes the intensity of spline and integrity problem be solved, and effectively improves forcing press and to be hit the durability of pressure.
