Incoming calls to the phone or phone in the picture, we will give you the most sincere offer! Look forward to your call Tel: 13,935,186,687 QQ: 1,774,479,104-WGJ Series bending machine is my factory has independently developed a versatile steel cold-formed equipment, a national initiative. For C steel, I-beam, angle, channel, rail, square steel, steel and other steel arch rolling, adjustable, fixed angle bend. With digital encoder programming, accurate positioning of the hydraulic control system, an automatic shape of the curved steel, high efficiency, easy to operate. And machining accuracy, mainly used in the tunnel, subway, hydropower stations, underground caverns. Smooth transmission, pressure, encoder positioning system, accurate positioning. Main technical parameters: profile Size 14-30 I-beam minimum bending radius ≥ 1.5m cylinder sliding speed 8-15mm/sec of the capstan speed 7-10r/min hydraulic system power a 25Mpa total power 11.9kw machine weight 2380kg tunnel dedicated cold machine-beam curved arch roll forming machine WGJ250 cold-formed steel equipment cold-formed profiles C channel steel cold-formed equipment hydraulic bending machine profile Cold Equipment Sales Tel: 13,935,186,687 QQ: 1774479104 call your pictures on the phone or the following phone, we will give you the most sincere offer! look forward to your call Tel: 13,935,186,687 QQ: 1774479104, characteristics and uses WGJ250 hydraulic bending machine is my factory research and development of new automatic-beam bending device. Hydraulic system, smooth transmission, pressure, accurate positioning, substantial increase in the tunnel I-beam machining accuracy. WGJ250 hydraulic bender is widely used in highway tunnel in China, the bending of beams, channels and sections of railway tunnels, subway tunnels, water conservancy and hydropower diversion culverts and natural gas pipelines, communication pipes, underground tunnels and other projects. The main technical parameters Item Unit Parameter minimum bend radius m ≥ 1.5m cylinder advancing speed mm / s 8-15 initiative roller speed r / min 7-10 hydraulic system pressure Mpa 26 Total power Kw 7.4 Machine weight kg 2380 Dimensions M 2.4 * 1.5 * 1.4 Third, the structure of the hydraulic cold-formed for the machine consists of two main motor and reducer group, active wheel. The passive wheel and pump motor, gear pump, relief valve, solenoid hydraulic steering valve cylinder composed workstation components. Fourth, the working principle of the I-beam on a bender, contact and deceleration driven wheel, the clamp locking handle feed, start the motor pump group, output by the electric oil pump pressure relief valve (adjustable pressure ) into the manifold to the cable valve, electro-hydraulic valve and fixed point switch (point into the point back) control cylinder, cylinder promote the I-beam with three support Cruises compression and bending deformation when start, the length of the cylinder propulsion process for 10mm-15mm, open the main motor to drive the I-beam, repeated operation required is reached. Bending system active wheel, the passive rollers made of special materials, the overall heat treated to reduce cruise wear, no scratches on the workpiece, longer life. ? The hydraulic bender WGJ250 hydraulic system adopt advanced hydraulic components, and its unique design of the hydraulic system, an increase of ejection rebound device, makes the top of the powerful, long life, avoid frequent maintenance Sales Tel: 13935186687 QQ: 1774479104
