Abstract

The invention belongs to the field of veneer reeling machines, and discloses a low-deformation veneer reeling machine which comprises a veneer reeling machine body, a supporting force rear plate is fixedly installed at the rear end of the veneer reeling machine body, a pair of cavity conversion sliding seats is slidably connected to the upper end of the supporting force rear plate, gooseneck hollow pipes are fixedly connected to the upper ends of the cavity conversion sliding seats, and the gooseneck hollow pipes are fixedly connected to the lower ends of the cavity conversion sliding seats. The right end of the gooseneck hollow pipe is fixedly connected with an isolation connector, the right end of the isolation connector is fixedly connected with an arc-shaped isolation supporting plate, and a pair of force bearing grooves are formed in the right end of the arc-shaped isolation supporting plate. Buffer and reverse acting force support is provided for a bent plate, the influence of deformation force of the plate and the pressure of a follow-up plate bending machine is reduced, the curved surface of the bent plate is effectively kept, the forming quality of the plate is improved, the bending precision of the plate is improved, and development of the plate bending machine body towards high-precision machining is facilitated.

Description

technical field [0001] The invention relates to the field of plate bending machines, and more particularly, to a low-deformation plate bending machine. Background technique [0002] The plate bending machine is a kind of equipment that uses work rolls to bend and form sheet materials. It can form parts of different shapes such as cylindrical parts and conical parts. It is a very important processing equipment. The working principle of the plate bending machine is to make the work roll move through the action of hydraulic pressure, mechanical force and other external forces, so that the plate can be bent or rolled into shape. According to the rotational movement and position changes of work rolls of different shapes, elliptical parts, arc parts, cylindrical parts and other parts can be processed. [0003] The upper roller of the symmetrical plate rolling machine is in the symmetrical position of the center of the two lower rollers, and the hydraulic oil in the hydraulic cyli...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when the plate rolling machine bends the plate, the bending deformation of the plate is only controlled by the pressure of the work rolls, and the shape of the bent plate cannot be maintained, and the bent plate will continue to bear its own deformation during the processing process Due to the impact of the force and the pressure of the subsequent plate rolling machine, a certain amount of springback deformation occurs, which reduces the forming quality of the plate and reduces its bending accuracy, which is not conducive to the sustainable development of the plate rolling machine.
