Description
The hydraulic top-roller universal plate bending machine is a medium-to-large-sized metal plate processing equipment with hydraulic drive as its core and multi-condition rolling capabilities. Leveraging the structural advantage of "universal adjustment of the top roller". it can realize integrated operations such as plate pre-bending. circular rolling. and circle correction. It is widely used in industries with high requirements for rolling precision. such as pressure vessels. chemical equipment. and wind power towers
Structural Design Core Structure: It adopts a three-roller or four-roller layout (with the three-roller universal type as the mainstream) featuring "active top roller + hydraulic adjustment of lower/side rollers". The top roller is the driving roller. rotated by a high-power hydraulic motor; the lower and side rollers are driven rollers. whose lifting. translation. or tilting is controlled by hydraulic cylinders. allowing flexible adjustment of their relative positions to the top roller.- Key Components: The top roller is made of high-strength alloy steel (e.g.. 42CrMo) and processed through forging. quenching and tempering. surface quenching. and other processes. Its diameter usually ranges from 150mm to 500mm. with strong load-bearing capacity. The hydraulic system is equipped with high-precision servo valves and oil pressure sensors to ensure the stability of roller adjustment. The frame adopts an integral welded structure. and internal stress is eliminated through aging treatment. resulting in excellent deformation resistance.- Auxiliary Configurations: Some models are equipped with side roller translation mechanisms. material supporting devices. and CNC operating systems. which can adapt to the rolling needs of plates of different specifications and improve operational safety and convenience.
Working Principle Pre-Bending Stage: Feed one end of the metal plate between the three rollers. The hydraulic system drives the lower roller to rise and the side rollers to tilt. making the edge of the plate closely contact the top and side rollers. Using the three-point extrusion principle. pre-bending of both ends of the plate is completed (eliminating the straight edge at the circular rolling interface). without the need for additional pre-bending equipment.- Circular Rolling Stage: After pre-bending. the active rotation of the top roller drives the plate to feed. Meanwhile. according to the preset rolling radius. the hydraulic system adjusts the height of the lower roller and the angle of the side rollers in real time. Under the continuous extrusion and friction of the three rollers. the plate is gradually bent into the required arc-shaped. cylindrical. or conical workpiece.- Circle Correction Stage: For workpieces requiring high precision. the roller position can be adjusted repeatedly to make the workpiece rotate multiple times between the rollers. correcting the arc deviation. This ensures that the roundness error is controlled within ±0.5mm (specific precision varies by machine model and specification).
Performance Features Universal Rolling Capacity: It can process various materials such as carbon steel. stainless steel. alloy steel. and non-ferrous metals. and is compatible with a wide range of plate thicknesses (usually 6-100mm. and up to over 200mm for large models). The minimum rolling diameter can reach 300mm. and the maximum can exceed 5000mm. It can realize the rolling of various shapes such as cylinders. cones. and arcs. with compatibility far superior to ordinary plate bending machines.- High Precision and Efficiency: The hydraulic drive system has a fast response speed. and the roller adjustment precision can reach ±0.1mm. Equipped with a CNC system (for some models). it can realize parameter presetting and automatic rolling. reducing manual intervention. The active rotation design of the top roller improves the stability of plate feeding. and the rolling efficiency of a single workpiece is 3-5 times higher than that of manual or semi-automatic plate bending machines.- Operation and Safety: It adopts a PLC control system + touchscreen operation interface. which can store multiple sets of processing parameters and support program calling and modification. It is equipped with safety devices such as overload protection. emergency stop. and roller anti-fall. preventing equipment damage caused by misoperation or excessive load and ensuring the safety of operators.
Products Description
Application Scenarios Industry Fields: It is mainly applied in heavy industry fields such as pressure vessel manufacturing (e.g.. storage tanks. reaction kettles). wind power equipment (towers. flanges). chemical pipelines. shipbuilding. and metallurgical machinery. It can also be used for processing arc-shaped parts of large steel structures (e.g.. bridges. factory building steel structures).- Production Needs: It is suitable for medium-to-large batch. high-precision plate rolling operations. especially capable of meeting the complex rolling needs of thick plates and high-strength steel plates. It is one of the key equipment for large manufacturing enterprises to achieve standardized and efficient production.
