hydraulic 4-rollers rolling machine

time:2015-06-04 16:55:13 | shot:times

Features:

1) This model refers to European four-roller plate bending machine technology and finalizes the design home-made. 

2) Pre-bending and bending can be completed on the machine without U-turn. Plates can be bent to be tubular, arc or even cone-shaped work pieces 

3) Bearings are new heavy duty rolling bearings with low speed and high efficiency. It can continuously work 20000 hours without fault against full load. 

4) High working accuracy. Bottom and side rollers can lift and regulate automatically. The synchronous accuracy is ±0.2mm.Also bottom and side rollers can lean some angle and keep it to lift together, that is, it can ensure absolute and relative synchronous movement not more than ±0.2mm. 

5) Cone-shaped work pieces can be bent with supplemental device on one end of top roller. The whole machine has good rigidity, low gravity and smooth motion. Rigidity of rollers is 1/1000. 

6) The main valves of the hydraulic system are the products of the Taiwan Northman Co., Ltd. The flow passage is formed by casting, which brings the advantages of large flow volume, low resistant force, low pressure loss, low heat creation and reliable performance. 

7) The hydraulic system has the oil sucking & returning filters to keep the oil clean; the air breather to normalize the tank breathing and water evaporating; the double security device in the system is to ensure the operation security. The radial quick joints particularly used in mining bad environment are applied in the hydraulic piping to avoid leaking. The piping pressure is 30Mpa. 

8) Crucial parts and components such as rollers, electric elements, and hydraulic parts have passed strict sifter and their qualities are reliable. 

9) Its hydraulic oil is 46# durable oil. Lubrication is by dry oil.
