Abstract
The invention discloses an upper roll driving and balancing device of a four-roll plate bending machine. The upper roll driving and balancing device comprises a stand, wherein the bottom of the stand is fixedly welded with a pedestal; a box body is arranged in a guide rail of the stand; a plurality of planetary speed reducers are arranged on the box body; a hydraulic motor is arranged on the planetary speed reducers; an input shaft of the planetary speed reducers is provided with a pinion; an output shaft of the planetary speed reducers is supported through a self-aligning roller bearing; the self-aligning roller bearing is fixed in a box cover; the box cover is connected with the box body; a bull gear which is engaged with the pinion is arranged below the pinion; the box body and the box cover are arranged on the bull gear through tapered roller bearings; the bull gear is arranged on an upper roll; and an oil cylinder is connected between the box body and the pedestal. According to the upper roll driving and balancing device, the requirement of large torque required for driving the upper roll of the four-roll plate bending machine is met. The upper roll driving and balancing device has a compact structure and is safe and reliable in operation.
Description
Technical field
The present invention relates to a kind of metal forming machinery, be specifically related to transmission of a kind of large-scale four-roll plate bending machine top roll and bascule.
Background technology
Existing middle-size and small-size four-roll plate bending machine top roll drives and adopts single planetary reducer to add the hydraulic motor driving.Bascule is employed in main drive top the back-pressure cylinder structure is set.But on large-scale four-roll plate bending machine, single planetary reducer then is difficult to reach torque demand.Promptly enable to reach, this planet decelerator series specification will be very high, and volume is also very huge, involve great expense, and domestic very difficult production.Hydraulic motor also is difficult to reach torque demand simultaneously, and buying is also very difficult.Receive structural limitations, the back-pressure oil cylinder can't be installed.This just realizes maximizing to four-roll plate bending machine and has brought difficulty.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, a kind of top roll transmission and bascule that is used on the large-scale four-roll plate bending machine is provided.
Technical scheme: for achieving the above object, the invention provides transmission of a kind of four-roll plate bending machine top roll and bascule, comprise frame; Said frame bottom is fixedly welded with base, in the said rack rail casing is installed, and a plurality of planetary reducers are installed on the said casing; Hydraulic motor is installed on the planetary reducer, on the power shaft of planetary reducer pinion is installed, the output shaft of planetary reducer is through the self-aligning roller bearing supporting; Said self-aligning roller bearing is fixed in the case lid; Case lid is connected with casing, and the pinion below is provided with the gear wheel with pinion, and casing and case lid are installed on the gear wheel through taper roll bearing; Gear wheel is installed on the top roll, is connected with oil cylinder between said casing and the base.
Four planetary reducers are installed on the said casing, and said planetary reducer is fixed through screw and casing.
Said case lid is connected with casing through bolt.
Said oil cylinder top is connected with casing through bearing pin one, and the oil cylinder bottom is connected with base through bearing pin two.
Be installed in the gear wheel on the top roll by four planetary reducers through direct drive of pinion; To drive top roll; The reductor output links to each other with case lid through self-aligning roller bearing, and to reduce reductor output moment of flexure, casing is used to install planetary reducer; Bear the moment of torsion of planetary reducer simultaneously, casing passes to the veneer reeling machine frame with moment of torsion.Two oil cylinders are connected with casing through bearing pin, are used for keeping the top roll balance, can realize the top roll perk again simultaneously, so that roll the smooth taking-up of cylindrical shell.
Beneficial effect: the present invention has realized that the four-roll plate bending machine top roll drives the requirement of required high pulling torque.The planet speed-reducer series specification will be very low simultaneously, and volume is little, technology maturation, and price is lower, is convenient to buying; The hydraulic motor discharge capacity is less, and power is lower, can reach energy saving purposes; Also satisfied simultaneously the requirement of top roll balance; Top roll transmission of the present invention and balance device structure are compact, and be safe and reliable to operation.
