Product Description

In the production process, each bend of the bender is completed by bending multiple times. During the machining process, the elbow is effectively placed on the bending machine so that the device directly applies the bending moment to the steel pipe. In this way, the portion of the steel pipe is deformed in an appropriate amount to form a certain angle to achieve the purpose of bending.

In the basic process of the pipe bending machine, the rear end clamp clamps the steel pipe and then effectively moves forward through the fulcrum of the front lower die master cylinder, so that the steel pipe can bend and deform the mold curve along the middle of the upper until the bending is completed, and the elbow Being processed. The deformation of the Mid-Autumn Steel Pipe mainly occurs in the upper mold.

The upper die of the pipe bending machine is mainly used as a tire. In operation, the curve is determined according to the critical value of plastic deformation of steel pipes of different materials and specifications, so different steel pipes correspond to different upper molds according to the reasons of wrinkles.

During the bending process of the bender, the inner tube of the elbow should not be placed on the side close to the front clamp, and should be placed on the side close to the bending cylinder of the lower mold, and the rear portion of the inner tube is about **0 mm from the rear of the upper tire. For the first 3 bends, the lift of the curved cylinder should not be too large.

During the latter step of the bending machine elbow, the bending of the bending cylinder is gradually increased, knowing that the steel pipe effectively contacts the highest point of the upper tire arc, so that the steel pipe can be smoothed during the bending process, and the steel pipe is not unstable.

The bending machine steel tube needs to adjust the inner tube effectively before bending. The inner tube of the elbow must be in a self-locking position so that the inner wall of the steel tube can be effectively supported and then bent. By using the above measures, the bending machine can prevent the occurrence of steel pipes. wrinkle.
