Hydraulic 3 Roller-Symmetrical Rolling Machine

Specifications1. Competitive price2. Innovative design3. High-quality machine4. Attentive service5. A strong technique team6. With cone rolling functionSpecification: Max bending thickness(mm): 16Max bending width(mm): 2500Diameter of top shaft(mm): 300Diameter of bottom shaft(mm): 250Motor power(kw): 15Central distance between bottom shaft(mm): 370This machine belongs to hydraulic three-roller plate bending machine, which is used to roll the plate into round shape, U-shape, multistage R and other different shape(for example, rolling cone-shape), and the top roller can make up-down movement. Rolling round is achieved by lower roller movement droved by reducer. Due to the level of lower roller will not change, it is easy to feed the plate and operate. Main StructureThe main structures include upper roller device, vertically movement device for upper roller, down roller device, initiative running device, overturn device, machine frames, the left and right, bottom base. 1). Upper roller device include main oil tank, base frame for upper roller, adjustable axletree on both sides for upper rollers and etc. Main oil tank and piston pole belong to 45# forged parts, inter surface of box polished, the surface of piston pole plated by Cr. Pressurized loop choose Yx type from Japan. The pressure of material shape is from cavity work without pole. Piston pole of main oil box connect with axletree from of upper rollerThe upper roller is designed as drum shape. Normally utilize 0.7 load of upper roller to mend deform degreeOn the both side of upper rollers, install two rows and two lines adjustable axletree. 2). The movement device vertically for upper rollerDirectly drive with double oil boxes and the highest pressure for work reach 19.5Mpa. There are two roll axletrees on both sides of upper rollers. The base frame of these roll axletrees may move vertically with the help of removable piston pole along the trace of kickstand guide. The displacement transducer installed on both sides of the axletrees, so that the quantity display can show movement distance of upper rollers3). The device for down rollers and the movement device horizontally. The device for the down rollers include down rollers, axletree frame of down rollers, gears for down roller drive, the base frame of sliding bearings for down rollers, etc. The key initiative gear drives the input gear which drives the upper roller. 4). Main transmission deviceThe main transmission device include main engine, speed reducer. The main transmission device may roll in the positive and negative direction in order to provide the power for material roll.
