The cone roller is a hydraulic cone three-roller rolling machine. The upper roller performs an up and down movement at a symmetrical position between the two lower rollers, powered by a hydraulic cylinder to adjust the movement. Both front and rear sections are freely adjustable to ensure the size of the cone curl. Its features include safety and stability. The root cone roller is driven by a reduction gear box, rotating through a universal joint shaft to provide power for the sheet material movement and mechanical transmission. The overall structure is integral, with a simple foundation and easy to move. It features electric rolling and hydraulic pressing down. Basic equipment configuration: 1. Working rollers: three solid rollers with a conical shape, made of 40Cr material with hardness of HRC35-40, the roller shafts are treated with quenching and tempering to prevent surface scratching. Each lower roller has a fixed positioning line for ease of rolling workpieces. The working rollers are important working components of the equipment, with the roller surface heat-treated hardness reaching HRC40-50. 2. Frame: machined by a boring mill, ensuring assembly accuracy, concentricity, and parallelism. The base and frame mating parts are precision machined to improve assembly accuracy, equipment operation accuracy, and lifespan. The frame is the main load-bearing component of the machine, requiring sufficient strength and rigidity. It is made of a whole steel plate welding structure, with the welds strictly inspected and vibration时效 treated to eliminate internal stress. The left and right uprights are fixed to the base with screws, connected by rods in the middle to ensure the frame remains in an accurate position.
