Bend machine is mainly used for carbon steel and alloy steel price of bend forming, if you need the product is stainless steel elbow, please select cold push bend machine equipment mainly include: frame, main oil cylinder plate (including the main oil cylinder), active pushing plate, the plate before, semi-automatic feeding mechanism, intermediate frequency adjust coil frame (including intermediate frequency heating coil), intermediate frequency power supply, electric control system, etc.

The raw material of steel pipe is seamless steel pipe, welded steel pipe and rolled steel pipe.

Put the cut raw materials on the core rod of the elbow mold, put the intermediate frequency induction wire trap on the end of the elbow mold core, start the cooling water pump and the intermediate frequency power supply, heat the raw materials to about 800°C, and then start the pushing machine to push the elbow.

Select the main push pump according to the elbow, select the speed of feeding, the gate, the mandil rod heated to the working temperature began to push, the work speed is adjustable, push to the middle point of the machine automatically stop, the hydraulic gate gate dead, the core rod feeding, loosen the gate back to the end, the gate gate to the outside diameter of the rod began to push.Note: the main push pump can be used at the same time, generally only one can be used.It can also be used to step back without stopping.Reverse pump can not be used at the same time, only one can start, the other standby.Feeding pump can only be used when feeding.The safety pressure of the main oil pump hydraulic system is set as that of the auxiliary cylinder hydraulic system.There are travel switches at both ends of the push machine travel, the actual travel should be less than the maximum travel, that is, the two ends of the push plate before and after the actual end are left with some margin, so as to avoid the cylinder piston running to.

Introduction of hydraulic parts of elbow machine

The head and bed parts of the elbow machine are designed with reinforcing bars, and the internal stress is eliminated by annealing treatment. The whole machine has enough strength and rigidity to prevent permanent deformation.Directly from the nose upper insert when transmission shaft assembly, installation precision, convenient maintenance, bend the spindle and sprocket and integral forging, the whole processing, overall hob, keyless connection, force uniform, driven by double oil cylinder, pipe bending process, the turning arm before bending close to set the Angle of the hydraulic system of automatic throttling buffer, greatly improved the precision of bending, fast restoration, the return processNear the beginning point is provided with a throttle buffer, which greatly improves the reset precision and working efficiency.Full hydraulic drive, microcomputer controller can preset 16 kinds of angles, can be used to push the elbow molding machine foot switch to complete the whole process, hydraulic clamping, hydraulic pressure, hydraulic elbow, hydraulic core pulling, five oil cylinders (can increase the car feeding and space corner function).
