Abstract

The utility model relates to an upper supporting frame of a curve down three-roller coiling machine. According to the technical scheme provided by the utility model, an upright column is arranged on a lathe bed of a coiling machine; a guide rail is formed at one side of the upright column; a cross beam is arranged on the guide rail; a plurality of rollers are arranged on the cross beam; a cylinder is arranged on the upright column by a cylinder seat; a piston rod of the cylinder is connected with a pulley seat; a pulley which is supported by a rolling bearing is arranged on the pulley seat; a chain is arranged on the pulley; one end of the chain is fixed on the upright column, and the other end of the chain is connected with the cross beam; the cross beam can be driven by the chain to move up and down along the guide rail; and the rollers are fixed on the cross beam by a roller seat and the rolling bearing. Compared with the prior art, the upper supporting frame of the curve down three-roller coiling machine can coil thinner plates with a larger diameter, the application range of the coiling machine is widened, and the controllability of a coiling process and the using safety of equipment are improved.

Description

Camber line down-adjusted three-roll plate bending machine bracket

Technical field

The utility model relates to a kind of bracket, and especially a kind of camber line down-adjusted three-roll plate bending machine bracket belongs to the stress metal manufacture field.

Background technology

When at present both at home and abroad the general cylindrical shell equipment of rolling rolled the big barrel dliameter workpiece of thin plate, because of the effect of workpiece self gravitation, workpiece true form 13 was compared with the theoretical shape 14 of workpiece, and workpiece openings brings out existing tenesmus distortion (as shown in Figure 1) in various degree.Existing various veneer reeling machine is by self distortion of device very difficult control workpiece in the process of rolling.Like this, not only can influence carrying out smoothly of the process of rolling, and might produce the quality that plastic deformation influences final finished because of plate.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of camber line down-adjusted three-roll plate bending machine bracket that prevents plate side direction distortion in cylindrical shell is provided.

According to the technical scheme that the utility model provides, on the veneer reeling machine lathe bed, column is installed, be provided with guide rail in a side of column, crossbeam is set on guide rail, a plurality of rollers are installed on crossbeam; By oil cylinder seat oil cylinder is installed on column, the piston rod of oil cylinder links to each other with pulley base, and the pulley by the rolling bearing supporting is installed on the pulley base, and chain is set on pulley, and an end of described chain is fixed on the column, and the other end of chain is connected with crossbeam.

Described crossbeam can move up and down at the traction lower edge of chain guide rail.

Described roller is fixed on the crossbeam by roller seat and rolling bearing.

The utility model compared with prior art can roll the bigger sheet material of the thinner barrel dliameter of plate, has enlarged the veneer reeling machine scope of application.And increased the process that rolls controllability, improved the security that equipment uses.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete accompanying drawing.

Shown in Fig. 2 ~ 4: camber line down-adjusted three-roll plate bending machine bracket comprises roller 1, roller seat 2, crossbeam 3, pulley 4, pulley base 5, chain 6, oil cylinder 7, column 8, veneer reeling machine lathe bed 9, rolling bearing 10, guide rail 11, workpiece 12 etc.

The utility model is installed column 8 on veneer reeling machine lathe bed 9, be provided with guide rail 11 in a side of column 8, and crossbeam 3 is set on guide rail 11, and a plurality of rollers 1 are installed on crossbeam 3; On column 8, oil cylinder 7 is installed by oil cylinder seat, the piston rod of oil cylinder 7 links to each other with pulley base 5, and the pulley 4 by rolling bearing 10 supportings is installed on the pulley base 5, and chain 6 is set on pulley 4, one end of described chain 6 is fixed on the column 8, and the other end of chain 6 is connected with crossbeam 3; Described crossbeam 3 can move up and down at the traction lower edge of chain 6 guide rail 11;

Described roller 1 is fixed on the crossbeam 3 by roller seat 2 and rolling bearing.

The course of work of the present utility model: when hydraulic oil injected oil cylinder 7 cavity of resorptions, the piston rod of oil cylinder 7 drives pulley base 5 and pulley 4 rises, and under the traction of chain 6, the crossbeam 3 of column 8 one sides moves up along guide rail 11 simultaneously.Along with the continuous variation that rolls workpiece 12 curvature, the roller 1 on the crossbeam 3 highly also constantly changes as required, remains and the contacting of arc-shaped workpiece 12, and plays the effect of " holder ".Prevent workpiece 12 because of the local deformation that the gravity effect causes, make the process of rolling obviously smooth than conventional roll mode.
