Rolling machine

Abstract

The invention provides a veneer reeling machine. The veneer reeling machine comprises two side roll fixing portions used for fixing two side rolls respectively and two horizontal adjusting portions used for adjusting the two side rolls to move in the horizontal direction respectively. Each side roll fixing portion comprises two machine frames used for supporting the two ends of the corresponding side roll, two inclined guide grooves formed in the machine frames, two bearing pedestals installed in the inclined guide grooves and used for supporting the corresponding side roll, first drive units connected with the bearing pedestals and used for moving the bearing pedestals, and a base fixed at the bottom of the machine frames. Each horizontal adjusting portion comprises two guide rails clamped with the corresponding base and used for adjusting and fixing the horizontal distance between the side rolls and an upper roll and second drive units used for moving the corresponding base. Two first drive units drive the two corresponding bearing pedestals to move in the corresponding inclined guide grooves simultaneously, and therefore the positions of the side rolls are adjusted aslant; the second drive units drive the bases to move on the guide rails, and therefore the positions of the side rolls are horizontally adjusted.

Description

technical field [0001] The invention relates to forging equipment for processing metal plates, in particular to a plate rolling machine for rolling plates with different thicknesses. Background technique [0002] The plate rolling machine is a kind of processing equipment that bends the metal sheet into the required circular, arc or conical shape. The plate rolling machine works on the principle of three points forming a circle. By adjusting the side roll of the plate rolling machine and the relative position between the upper roller to obtain a predetermined shape. [0003] At present, the four-roller plate rolling machine is widely used because it has the advantages of wide versatility, small residual straight edge, automatic positioning of the plate, and one-time feeding to complete the rolling process. In the prior art, the four-roll plate bending machine with side roll tilt adjustment can only adjust the position of the side roll along the inclined guide groove, that i...

AI Technical Summary

Problems solved by technology

In the prior art, the four-roll plate bending machine with side roll tilt adjustment can only adjust the position of the side roll along the inclined guide groove, that is, the space adjustment range is limited, and it is difficult to further adjust the side roll and the upper roll or Centerline distance between lower rolls

If a larger rolling force or rolling moment is required, the position can only be adjusted along the inclined guide groove, which increases the load of the frame and causes the deformation of the side rollers, which is of great importance to the rolling process of the plate rolling machine. Adverse

When rolling thicker plates, the rolling torque of the existing four-roller plate rolling machine is limited, which cannot effectively roll thick plates
