C-shaped steel purlin machine cold bending machine

The finished products of C-shaped steel rolled by C-shaped steel purlin machine and cold bending machine have good tensile bending and compression performance, good flatness, full-automatic fixed length cutting, automatic punching, good degree of automation and convenient installation. The products can be used as the main stress-bearing structure of large and medium-sized industrial and civil buildings, such as the roof load-bearing and wall horizontal support of factory buildings, warehouses, locomotive hangars, aircraft hangars, exhibition halls, cinemas, stadiums, and market flower sheds. Cold formed steel is the main material for making light steel structure, which is made of steel plate or steel strip by cold bending

c-shaped steel purlin machine cold bending machine improvement process:

add length measuring device and flying saw. When the pressing length reaches the set length, the flying saw acts and automatically cuts off the profile

add a hydraulic punching equipment for punching side holes, punching four holes at a time, and the flying saw cuts off from the middle, thus forming two side holes at the head and tail of two adjacent sections of C-section steel

add another equipment for punching middle holes, which can punch 16 middle holes according to the spacing set by the user during the strip steel pressing process. In view of the requirements of the new C-shaped steel to punch double holes in the middle of the profile, the side hole punching die with 4 holes is changed to a 2-hole die, and the procedure of punching side holes is modified, so that the side hole punching equipment can punch double holes in the middle, and the hole spacing is set by the user, and 8 groups of double holes can be punched

working procedure of cold bending machine of C-shaped steel purlin machine:

before using the equipment, check whether the connections at all places are secure, whether the mounting bolts and nuts are tightened, and add enough lubricating oil in the left and right chassis before powering on and starting the machine for commissioning. First, operate the empty vehicle carefully and observe whether there is vibration, noise, oil coming from the oil window, whether the movements of all parts are coordinated, and then install the mold. When installing the mold, To cut off the power supply, manually move the motor belt or big gear to rotate the workbench and raise the sliding seat to the high point, so that an object can be supported between the workbench and the bottom surface of the sliding seat to prevent the sliding seat from falling naturally, causing an accident
