Square Pipe Roll Forming Machine

Square Pipe Roll Forming Machine

The square pipe roll forming machine is a machine that shapes square tubes. Its four-direction forming stands form seventeen different types of square tubes. The four-direction roll forming stands usually have two stages and have a fixed curvature along the axis of rotation. The number of rolls used is based on the diameter of the square tube to be formed.

This invention is characterized by its ability to minimize problems with insufficient rigidity at the shoulder and corner portions. Moreover, it reduces the chances of indentations and scratches in the finished product. This feature makes the square pipe roll forming machine a highly versatile machine. It is particularly useful for making sanitary products.

A square tube roll forming machine consists of several stages. The first stage is used for initial forming of the raw tube. The second stage - the final forming of the raw tube - is performed by a second forming roll stand. The forming roll stands are arranged in a four-direction roll structure, with the upper-lower forming roll pair arranged at the center of the tube's side portions.

The square tube roll forming machine can adopt a combination of different forming processes. For example, it can adopt a four-direction roll process for raw tubes and an alternating two-direction roll process for the first and last stages. Alternatively, it can insert a two-direction forming roll between the two-direction processes.

Another important feature is its ability to form wide product dimensions. A wide range of product dimensions requires multiple forming stages. However, it can help reduce the overall equipment cost by reducing the number of forming stages. Further, it can help control the quality of the square pipe and prevent corrosion. Its design is also easy to maintain.

The machine should be cleaned on a regular basis. Clean all parts, including the vertical roller device and the welding seam extrusion device. Make sure to grease the machine with lubricant for rust prevention. The horizontal roller frame should also be regularly scrubbed. The guide rail and inner side of the frame should also be greased. During operation, the nuts should be checked for tightness. If any of them loosen, stop the operation and replace them.

The main advantages of the square tube roll forming machine are its ease of operation and low cost. This machine can be operated by a single operator or several. Operators should be careful not to touch the machine. Operators should have fixed positions and should not move around. They must also keep a record of shifts.

Another characteristic of a square pipe roll forming machine is its ability to weld. Welding can be done with HF contact, electric resistance, or laser beam welding. Depending on the material, the right type of welding is important.
