Abstract
The utility model relates to an electric double screw press. The press comprises a body, a motor vertically arranged on the body, a flywheel driven by the motor, a screw arranged on the flywheel, a screw and nut combined body arranged on the screw through a screw pair, an outer nut arranged on the screw and nut combined body through a screw pair, a sliding block arranged on the outer nut, and a lifting oil cylinder which is fixed on the body and connected with the sliding block. The electric double screw press is energy-saving and can be widely applied to forging and pressing forming industry, the motor is low in power, and a motor shaft is difficult to break.
Description
Technical field
The present invention relates to a kind of electric double helix forcing press, can be widely used in the excellent suitability for press forming industry.
Background technology
The prior electric fly press all is the single-screw auxiliary driving, and it is big to consume energy in the slide block backhaul lifting process, and the power of motor that drives flywheel is excessive, and the motor shaft easy fracture, and power consumption is big, and transmission efficiency is low.
Summary of the invention
The object of the present invention is to provide a kind of energy-conservation, power of motor is little, the motor shaft electric double helix forcing press of easy fracture not.
In order to achieve the above object, electric double helix forcing press of the present invention comprises fuselage; The vertical motor that is installed on the fuselage by motor-driven flywheel, is installed in the screw rod on the flywheel; Same body rod through screw pair is installed on the screw rod is female; Be installed in the outer nut on the body rod mother through screw pair, be installed in the slide block on the outer nut, be fixed on the fuselage and the lift cylinder that links to each other with slide block.
Electric double helix forcing press of the present invention, said by motor-driven flywheel, can be by motor direct-drive.
Electric double helix forcing press of the present invention, said by motor-driven flywheel, can drive through machine driving.
Electric double helix forcing press of the present invention, said machine driving drives, and can be gear drive and drives.
Electric double helix forcing press of the present invention, said machine driving drives, and can be belt transmission and drives.
Electric double helix forcing press of the present invention, said female with body rod, its bar lead compares >=2 with the helical pitch of box thread helical pitch.
Electric double helix forcing press of the present invention, said machine driving drives, and is not limited to gear drive, belt transmission type of drive, also can be other type of drive.
Electric double helix forcing press of the present invention, said female with body rod, its bar lead compares >=2 with the helical pitch of box thread helical pitch, and promptly its bar lead is that the box thread helical pitch is more than 2 times or 2 times.
Electric double helix forcing press of the present invention; Its operation principle is: motor-driven flywheel rotation, flywheel drive the screw rod rotation, screw drive with the female rotation of body rod and on rotate synchronously with screw rod after moving to the screw rod boss; Move downward thereby drive outer nut and slide block, realize excellent suitability for press forming.After the strike, the energy of fly wheel system all discharges and finishes.Then,, slide block is risen to predetermined altitude, accomplish an operation cycle by lift cylinder.
Electric double helix forcing press of the present invention, said female with body rod, external diameter is screw shaped, and internal diameter is nut type, but the hand of thread spiral of external screw rod and inner nut must be opposite.
Electric double helix forcing press of the present invention, said double helix drive mechanism is to increase by a cover screw pair again in original fly press screw pair outer ring, forms the double helix auxiliary driving.Its special character has been to adopt outer for being the female part of the same body rod of " mother " in " bar ".By screw rod with to form inside spin with body rod female " mother " secondary, by forming the external spiral pair with outer nut with body rod female " bar ", so by screw rod, formed double helix auxiliary driving structure with body nut and three parts of outer nut, abbreviation double helix drive mechanism.Double-stranded employing, screw rod and flywheel do not rotate and purpose of energy saving when having realized the lifting of fly press slide block.
Electric double helix forcing press of the present invention when the slide block backhaul, is risen by the direct driving sliding block of lift cylinder, and screw rod, flywheel itself are motionless, like this, have just reduced energy consumption.
Electric double helix forcing press of the present invention is the female transmission of the same body rod of box thread helical pitch more than 2 times or 2 times owing to adopted the bar lead, the employing of this helical pitch ratio; Increase the revolution of flywheel, prolong the time that flywheel arrives rated angular velocity, reduced the power of motor; Simultaneously; Can economize on electricity 40%, energy-saving effect is remarkable, and motor shaft is easy fracture not.
Electric double helix forcing press of the present invention, during slide block down, screw rod rotation drives with body rod is female and rotates, and on move on to behind the screw rod boss with threaded synchronous rotation, at this moment, slide block just begins descending.At this moment therefore screw rod and mobile with not having between the female interior mother of body rod, does not have friction mutually.Like this, when slide block down hit, the transmission efficiency of double helix auxiliary driving and single-screw auxiliary driving changed very little.
Electric double helix forcing press of the present invention, the direct driving sliding block of lift cylinder moves up and down, and is convenient to the Installation and Debugging of mould.
In sum, electric double helix forcing press of the present invention, energy-conservation, power of motor is little, and motor shaft is easy fracture not.
