Description
Technical field
The present invention relates to metal forming machinery, particularly super wide plate bending machine technical field of structures.
Background technology
Existing a kind of multiunit upper supporting roller device veneer reeling machine, top in top roll, multiunit upper supporting roller device is set, every group of upper supporting roller device is installed in the crossbeam bottom surface of upper supporting roller device top again respectively, every group of upper supporting roller device adds different-thickness in advance when installing and adjusts backing plate, improve upper supporting roller device mounting center height, because of roll bending is created in the amount of deflection of crossbeam, guarantee the precision of roll bending goods in order to the compensation veneer reeling machine.When rolling the different size steel plate, must change again and be installed in upper supporting roller device adjusting pad plate thickness, could guarantee corresponding roll bending goods precision.So bring roll bending preparatory process duration, fitting operation inconvenience when this a kind of structure rolls the different size steel plate for super wide plate bending machine; Or, cause shortcomings such as the goods precision is low because of minimizing adjustment backing plate operation does not reach the requirement of corresponding specification roll bending compensation amount of deflection.
Skewback is equipped with in the top of the roller seat of existing another kind of upper supporting roller (being top backing up roll), and the adjustment wedge is housed above the skewback, with adjust that wedge is connected electronic pull bar and motor arranged, cooperate with the adjustment wedge compressing member be housed.This kind device has the vertical structure size of electronic pull bar and motor for vertically regulating the upper supporting roller device separately respectively, influences the upper supporting roller physical dimension, can only regulate inefficiency, inconvenient operation respectively.Described compressing member has only a cover back-pressure device such as an independent pull bar, spring, pressing plate, and as above support roller device is widened, and is difficult for balance, can not all be adjacent to the crossbeam baseplane.
Summary of the invention
The object of the invention is to design a kind of prior art defective that overcomes, and shortens the roll bending preparatory process time, makes roll bending more convenient to operate, improves higher roll bending goods precision, can regulate the veneer reeling machine of multiunit upper supporting roller device automatically fast simultaneously.
The present invention includes the crossbeam that is provided with base plate, below crossbeam,, between top roll and crossbeam, multiunit upper supporting roller device is set by the top roll of bearings; It is characterized in that every group of upper supporting roller device is lifted on the lower end of crossbeam by spring, fixedly connected fixing vertically wedge down in the upper end of upper supporting roller device; At the fixedly connected oil cylinder of the lower end at crossbeam two difference, the expansion link of two group oil cylinders is coaxial relatively, and be parallel to top roll, between two expansion links of two group oil cylinders, connect articulated beam, on the described articulated beam uniform vertically on wedge, each lower surface of vertically going up wedge respectively with corresponding fixing vertically under the upper surface of wedge contact; The forward and backward side in crossbeam lower end is the stationary positioned seat respectively, at two relative medial surfaces of positioning seat the keyway of vertical direction is set respectively, and each forward and backward side of organizing the upper supporting roller device is connected with positioning seat by the feather key that is engaged in the keyway.
The present invention vertically goes up wedge by articulated beam and is fixed into one each, work simultaneously by two group oil cylinders, making each vertically go up wedge is synchronized with the movement, order about every group of moving every group of upper supporting roller device action of fixing vertical declivity sheet iron strip, vertically descend wedge and vertically go up the different gradient of wedge and produce different vertical displacements by every group, compensate the amount of deflection of crossbeam diverse location, simultaneously, mill the vertical direction keyway at positioning seat, guarantee upper supporting roller device vertical direction mobile guide by feather key.
The present invention has overcome the prior art defective, and the adjusted in concert multiunit upper supporting roller device shortens the roll bending preparatory process time fast, makes roll bending more convenient to operate, improves roll bending goods precision.
For every group of upper supporting roller device can be installed evenly, every group of upper supporting roller device is connected with crossbeam by four springs.Regardless of the length and width of upper supporting roller device, can both keep upper supporting roller device gravitational equilibrium, help the vertical displacement of upper supporting roller device better and regulate.
Concrete grammar is: fixedly connected four pull bars in the upper end of every group of upper supporting roller device, and each pull bar is set in respectively in the through hole of crossbeam base plate, the nut that on the pull bar above the crossbeam base plate, is threaded, the rod outer sleeve between nut and crossbeam base plate is put spring.
Description of drawings
