Description

Seven-roller straightener

Technical Field

The utility model relates to a seven roller straightener.

Background

At present, a straightening machine is a device for straightening plates and the like, the straightening machine extrudes the surfaces of the plates and the like through straightening rollers to change the straightness of the plates, and generally comprises an upper row of straightening rollers and a lower row of straightening rollers, for example, seven straightening rollers are adopted for the seven-roller straightening machine, and the upper surface and the lower surface of the plates are straightened simultaneously by the two rows of seven straightening rollers; generally, a pressure straightening mode is adopted, a motor drives a straightening roller to rotate, the plate is enabled to move forward while being straightened by means of friction force between the rotating straightening roller and the surface of the plate, in order to achieve compression required by the roller on the plate, the number of the straightening rollers is increased, the precision of a straightened product is higher, comprehensive cost and precision requirements are met, the seven rollers are the most commonly used number at present, and when the plate is bitten by the straightening roller, the product is enabled to bear deformation such as compression, bending and flattening in all aspects, and finally the straightening purpose is achieved. Meanwhile, in order to increase the applicability of the straightener, an adjusting mechanism is arranged on a roller frame provided with the straightening roller, but the conventional adjusting mode adopts a manual adjusting mode, so that the time and the labor are wasted, and the precision is poor; therefore, enterprises also develop an electric adjusting mode shown in Chinese patent CN201620991579.7 'a full-automatic vertical seven-roller straightener', but the bearing capacity of an electric adjusting structure is poor, so that the straightening effect is influenced; therefore, there is a need for a seven-roll straightener that can have a high precision adjustment function while not affecting the bearing capacity.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned not enough, provide a seven roller straightener with high accuracy regulatory function and do not influence the bearing capacity.

The purpose of the utility model is realized like this:

a seven-roller straightener comprises a plurality of upper straightening rollers and a plurality of lower straightening rollers, wherein the upper straightening rollers are arranged on an upper roller frame, the lower straightening rollers are arranged on a lower roller frame, the upper roller frame is fixedly arranged on a support, side supporting plates are arranged on two sides of the lower roller frame, a plurality of racks are vertically arranged on the inner surfaces of the side supporting plates, a plurality of gears driven by a progressive motor are arranged on the bottom surface of the lower roller frame, and the gears are meshed with the racks; a plurality of supporting oil cylinders are vertically arranged below the lower roller frame, and piston rods of the supporting oil cylinders vertically upwards contact with the bottom surface of the lower roller frame.

The utility model relates to a seven roller straightener, the top horizontal mounting of support cylinder's piston rod has a layer board.

The utility model relates to a seven roller leveller, the bottom surface of lower roll frame is provided with a plurality of recesses along its length direction, and has set proximity switch in the recess, and above-mentioned layer board is located proximity switch under, and the area of layer board is greater than the area of recess, installs the solenoid valve on the oil circuit of above-mentioned support cylinder, and proximity switch concatenates on the power supply loop of solenoid valve.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a step motor drive can be convenient finely tune to improve the precision, utilized the hydro-cylinder to play the supporting role to the roller frame simultaneously, make the roller frame more reliable and stable, precision when having guaranteed the aligning.
