Abstract
The invention relates to an anti-vibration carrier roller of an upper roller of a plate rolling machine for a large-scale boat. The anti-vibration carrier roller comprises an electric push rod, wherein the electric push rod is arranged on the bottom surface of an upper transverse beam and is connected with a regulating inclined iron, the lower inclined surface of the regulating inclined iron is pasted with the upper inclined surface of a carrier roller seat, the carrier roller seat is hung and fixed on the upper transverse beam by a spring assembly after a pull rod passes through a stripped hole arranged in the middle of the regulating inclined iron and a through hole of the upper transverse beam, the front and the back of the carrier roller seat are symmetrically provided with four carrier rollers to form the support of the upper roller, and the deflection deformation of the middle position of the slender upper roller is compensated. The anti-vibration carrier roller is characterized in that the front and the back of the carrier roller seat are symmetrically provided with two support frames, the support frames are fixed on the carrier roller seat through positioning keys and screws, and the lower ends of the support frames are positioned at the lower part of the upper roller with the dimension smaller than the diameter and are in contact with the upper roller surface to form a carrier holding shape. The anti-vibration carrier roller has the advantages that the downward displacement of the upper roller in the idle-load high-speed movement state is limited through the support frames arranged on the anti-vibration carrier roller, and the limitation of the carrier roller on the upward displacement of the upper roller is combined, so the smaller vibration and impact interference of the upper roller in the high-speed movement is realized; and the reliability, the safety and the operation performance are greatly improved.
Description
Technical field
The present invention relates to a kind of excellent suitability for press forming equipment, particularly a kind of vibrationproof carrying roller that is used for the top roll of large-scale plate-rolling machine for ship.
Background technology
Large-sized numerical control plate-rolling machine for ship top roll is the execution unit that rolls sheet material, and it is to be provided by master cylinder that the up-down of top roll drives.In veneer reeling machine work, for raising the efficiency, reduce non-cutting time, the no-load running speed of top roll can reach more than the 1500mm/min.And top roll is slender axles, and the fulcrum span at two ends is greater than 16m, and amount of deflection is big in the vertical direction middle part, in the process of quick reciprocating motion, bigger jitter phenomenon will occur like this.Top roll vibration (shake) when moving fast causes very big harm to machinery hydraulic system and electrical system of veneer reeling machine easily.At present, domestic and international most producers all realize through counter-bonification that through reducing the speed of service or increasing balance at the top roll two ends effect is not very desirable.
Summary of the invention
The purpose of this invention is to provide a kind of vibrationproof carrying roller that is used for large-scale plate-rolling machine for ship top roll, this vibrationproof carrying roller has compact conformation, vibration-isolating effect is obvious, operability is good, and is convenient to make installation.
The objective of the invention is to realize like this: a kind of vibrationproof carrying roller that is used for large-scale plate-rolling machine for ship top roll, comprise the electric pushrod that is installed on the entablature bottom surface, displacement transducer is installed on the electric pushrod; Electric pushrod connects the adjustment wedge, and on the adjustment wedge fit in plane and entablature bottom surface, and adjustment wedge lower inclined plane and roller seat ramp are fitted; Roller seat is fixed on the entablature by the spring assembly suspension after passing the middle cylindrical void of adjustment wedge, entablature through hole by pull bar; Both sides are provided with hold-down support before and after roller seat top and the adjustment wedge, and two hold-down supports are formed adjustment wedge displacement rails and prevented roller seat front and back displacement; Hold-down support is fixedly connected with entablature; Be symmetrically installed with four carrying rollers before and after the roller seat, form support, compensate the deflection deformation of elongated top roll middle part top roll;
It is characterized in that: before and after roller seat, be symmetrically arranged with two supports, support is fixed on the roller seat through positioning key and screw, and the support lower end is positioned at the bottom of top roll less than diameter, contacts with the top roll surface to form to embrace the holder shape.
The object of the invention can also be realized like this: the outside is circular-arc in the support.The support lower end is provided with reinforcement, and the reinforcement inboard is provided with the circular arc piece, and the circular arc piece contacts with the top roll surface.The circular arc piece is an antifriction alloy, is preferably copper alloy.
Advantage of the present invention and good effect are: to top roll restriction to bottom offset under the speed no-load and high motion state, to the restriction of top roll to top offset, realized top roll friction and impact interference in high-speed cruising in conjunction with carrying roller through the support on the vibrationproof carrying roller; Because the vibrationproof of top roll carrying roller makes whole aircraft reliability, security improve greatly; And because top roll vibrationproof carrying roller project organization is compact, manufacturing is easy for installation simple, the operability performance is good.
