Zhenghao Youbang Heavy Industry W12 Series Four-Roll Plate Rolling Machine
1. Structural Principle: Four-Roll Synergy for Efficient and Precise Sheet Forming
Zhenghao YoubangW12 Series 4-Roll Plate Rolling MachineAdoptTop roll drive + bottom roll clamp + independently adjustable side rollsClassic layout with four-roll synergy, structurally addressing pain points of traditional rolling equipment such as insufficient pre-bending, residual straight edges, and unstable precision.
Top Roll (Drive Roll)Core drive component: Driven by a hydraulic motor to deliver stable torque, it rotates the sheet metal for primary roll forming and features vertical adjustment to accommodate varying curvature requirements.
Lower Roller (Passive Clamping Roller): Fixed support structure that clamps the sheet with the upper roller to prevent slipping or shifting during processing, ensuring smooth feeding and uniform load distribution.
Side Roll (Left-Right Adjustable): Key precision control component that achieves horizontal tilting and feed movement via a hydraulic system to precisely adjust the bending curvature of the sheet metal.Complete pre-bending at both ends of the plate directly.No additional pre-bending equipment required; forms straight-edge-free cylinders in a single feed.
This structure uses four-roll linkage control to complete the operation in a single clamping.Pre-bending, Roll Bending, FinishingComplete process flow to simplify production steps and reduce secondary processing.
