Description

Two main motor-driven three rolls plate bending machines

Technical field:

The utility model relates generally to a kind of three rolls plate bending machine, relates in particular to a kind of two main motor-driven three rolls plate bending machine.

Technical background:

The main version of current domestic large-scale three rolls plate bending machine is that main motor-driven one a large-scale reduction box drives two lower rolls simultaneously and rotates synchronously, promptly two lower rolls of a main driven by motor main gear reducer driving carry out rolling of sheet material, not only structure is huge, processing difficulties, the cost height, and because the motor and speed reducer volume is too huge, thereby directly cause processing, the difficulty of fit on, the manufacturing cost that increases simultaneously that it is enough, make valuable product, do not possess the market competitiveness, the lower roll mechanical interference of large-scale three rolls plate bending machine is obvious simultaneously, causes a lot of power attenuations.

Described mechanical interference is meant: owing to depressing of top roll, occured bending and deformation by the coil plate, playing cladding material is elongated, inner layer material is compressed, neutral line length is constant, steel plate in the middle of two lower rolls place promptly with the stressed maximum in top roll contact position, distortion is also maximum, and steel plate is zero in lower roll contact position moment, and steel plate does not deform, when main transmission drive steel plate is mobile between three rollers, the lower roll of feeding one side and steel plate contact position, steel plate are not subjected to curved power yet, do not deform, steel plate does not elongate, steel plate is subjected to depressing of top roll through time in the middle of two lower rolls and has produced permanent deformation, and the steel plate outside is elongated, owing to be slab, roller is stressed very big, be difficult between steel plate and the roller producing sliding, just begun steel plate and rolled owing to distortion can produce a little on exit side lower roll surface, but owing to the outer field elongation of steel plate is successively carried out, and the rotating speed of two lower rolls is the same, and the material that is elongated has just produced interference between two lower rolls.The lower roll of feeding side has born all torsion torque that makes the steel plate bending distortion, the lower roll of exit side is passive rotation, but because steel plate is elongated, its linear velocity is accelerated, single configuration forces two lower roll linear velocities that drive are identical, make the positions such as lower roll axle journal of feeding side form overload easily and cause damage, also consumed a lot of powers of motor simultaneously.

The utility model content:

The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of two main motor-driven three rolls plate bending machine is provided, solved that the veneer reeling machine structure is huge, the difficulty of processing, fit on, power attenuation is many, mechanical interference takes place easily, and the cost height, problem such as service life is short can not satisfy the development need of industry.

The utility model is achieved through the following technical solutions:

A kind of two main motor-driven three rolls plate bending machine, include base, a described base left side, right two ends are separately installed with lower roller base, include a left side, go up roller seat for right two, the described lower roller base top that is positioned at the left side is hinged with upper left roller seat respectively, upper right roller seat presses down and is being positioned on the lower roller base on right side, two parallel lower rolls are installed between the described lower roller base, a described left side, between the upper right roller seat top roll is installed, be hinged with first oil cylinder between the described upper left roller seat outside and the base, described top roll axis stretches out outside the upper right roller seat, and shaft end and be installed between the support of base right-hand member and be hinged with second oil cylinder in the top roll; Shaft end is provided with drive in the described top roll; It is characterized in that: described two lower rolls provide power by separately reductor and motor respectively, and through the exposed gear transmission, device has brake between described motor and the reductor.

Described two main motor-driven three rolls plate bending machine is characterized in that: described top roll axis is installed on left and right going up in the roller seat by centrifuging bearing, and described lower roll axis is installed in the lower roller base of left and right side by composite bearing.

Described upward roll shaft installation shaft is held by compound cover and is changed the self-aligning bearing structure into, and plain edition three rolls plate bending machine three rollers are all for meeting the cover bearing, be sliding friction, because top roll is a driven voller, it rotates the frictional resistance of complete backup plate material, so when rolling than light sheet, because frictional force is less than the top roll resistance, top roll does not rotate, thereby can't roll, the top roll resistance when having reduced greatly to roll, when reducing energy consumption, also make this type can roll thinner sheet material, this bearing capacity is strong, and is not fragile.

The utility model adopts two lower rolls by independently driven by motor reductor driving separately, do not force two lower roll same rotational speed, but adapt to rotating speed separately automatically, and just fundamentally eliminated interference, twoly simultaneously drive the structure power attenuation and reduce greatly, can use two lower-powered motors, also more energy-conservation when reducing cost, and, can reduce module greatly because what use is two groups of reducing gears, structure is reduced, also solved the large module gear problem of difficult processing; This structure is particularly obvious in the advantage on large-scale veneer reeling machine.

The self-lubricated oil pump of lubricated employing of described exposed gear transmission, be connected oil pipe and place the casing top, with the gear teeth axle in the lubricated casing of electronic mode direct injection, do not need as conventional gearbox, to add a lot of oil like this, also solved lubricated halfway problem, and, realize that user's active is lubricated by switch control.

The utility model has the advantages that:

The utlity model has simple in structure, processing, easy to assembly, power attenuation is low, be not easy to take place characteristics such as mechanical interference, cost is low simultaneously, long service life, meet meticulousr, more energy-conservation, the more practical requirement of industry development, in will becoming, the main flow of large-scale veneer reeling machine development.
