Hydraulic pipe bending machine pipe bending tips and precautions

1、 Hydraulic pipe bending machine bending formula:

Learn to fold a bed, use your brain frequently, and first study the drawings carefully

Look at the drawings, choose the mold, and remember the shape of the mold

Look at the folding shape, select the machine tool, install the mold, don't be busy, lock it tightly in the center

Look at the blueprint, arrange the cutting sequence, ensure good cutting sequence, high efficiency, and fewer work errors

The arrangement of knife sequence SOP is based on the principle of easy to remember knife sequence. Folding forward and backward does not conflict, and folding from inside to outside is comfortable

2、 The hydraulic pipe bending machine is used for pulling, winding, and bending. When bending stainless steel pipes, pay attention to several points:

1. Adequate preliminary preparation; Accurately install bending molds, clamping molds, wrinkle resistant molds, attached push molds, core rod positions, and input bending angles.

2. Trial production work; Clamp the pipe on the bending die, and the pipe rotates with the bending die. When the pipe is pulled over the pressure block, the pressure block will bend the pipe around the bending die to ensure the accuracy of the bending of the pipe parts.

If the mold is installed improperly, it is easy to wrinkle and cause parts to be scrapped.

In tension bending, the position of the core rod relative to the bending point is very important. Although the core rod is advanced by a certain position relative to the bending point (the working end of the core rod enters the bending section of the pipe), the ellipticity can be reduced. However, when the core rod is advanced too much, it will increase the thinning amount of the pipe wall. Therefore, Hangzhou Jiaqi Stainless Steel reminds everyone to determine the position of the core rod accurately after bending the sample, fully ensuring the quality of the bent pipe product.
