Due to its technical improvement and perfection, the types of pipe rolling machines have been increasing, and the use steps have become more and more refined. The tube rolling machine will be briefly introduced below.


  • What are the precautions for the use of the tube rolling machine?

  • How to improve the production efficiency of the pipe-making machine?

  • What are the steps of using a tube rolling machine?


What are the precautions for the use of the tube rolling machine?

Refer to the instruction manual of the tube rolling machine. Never remove the quick connector when there is a load. This tube rolling machine uses oil as the medium, so it is necessary to clean and maintain the oil and the machine to avoid blockage or oil leakage, which will affect the use effect.


How to improve the production efficiency of the pipe-making machine?

1. The air supply system of the tube rolling machine drains water every day to keep the air path dry.


2. All transmission parts of the tube rolling machine are always oiled to keep flexible.


3. Clean the machine every day to keep the working surface of the machine clean and tidy.


4. The turbine box oil should be replaced once after six months of use, and the oil should not be less.


5. All the sliders and screw rods of the vertical bracket and horizontal bracket are often lubricated to keep the adjustment flexible.


What are the steps of using a tube rolling machine?

1. A metal heat treatment process in which the tube rolling machine is heated to a predetermined temperature and then slowly cooled after holding it for a certain period. The purpose of annealing is to:


①Improve or eliminate various structural defects and residual stresses caused by steel casting, forging, rolling, and welding, and prevent deformation and cracking of the tube rolling machine.


②Soften the ttube rolling machine for cutting.


③ Refine the grains and improve the structure to improve the mechanical properties of the tube rolling machine.


④Organization preparation for the final heat treatment and tube making


2. Slitting

The slitting of the stainless steel coil is to cut the stainless steel coil into the corresponding width for further deep processing and pipe making. The slitting process needs to pay attention to the scratches of the slitting knife to the coil, the width, and the error of the slitting. In addition, the slitting is related to the pipe-making process, and the slitting cloak and burrs are very important to the pipe-making process.


3. Welding

The most important process for tube rolling machines, stainless steel mainly adopts argon arc welding and plasma welding. The shielding gas for argon arc welding is pure argon, which is mainly used for welding stainless steel pipes below 3mm. Plasma welding has strong penetrating power, mainly welding 5- 8mm stainless steel tubes.


4. Weld bead grinding

During the welding process of the tube rolling machine, the weld bead on the outer surface needs to be polished and water-cooled accordingly. After the weld bead is cooled by water, the weld bead is directly polished with a water grinder until it is flat. Generally, 3 is added depending on the thickness of the stainless steel pipe. 5 sets of water mills for grinding and trimming the weld bead.


5. Plastic surgery

The process of a tube rolling machine is called extrusion production. All square and rectangular pipes are originally made from round pipes. The round pipes with the same circumference are produced and then extruded into the corresponding square and rectangular pipes. Mold shaping and straightening.


6. Cutting

The process of making and cutting stainless steel pipes is relatively rough. Most of them are cut with grinding wheels. After cutting, a cloak will be produced, which needs to be further trimmed. Another is a band saw cutting with relatively good accuracy. There is also a cloak heat treatment for special The tube used for the purpose needs bright heat treatment to make the ductility of the tube reach a higher level.


7. Polishing

Common product tubes and decorative tubes have several processes for surface treatment. Polishing is divided into 400#, 600#, 800#, while pulverized sand is divided into round sand and straight sand, including 180#, 240#, 400#, 600#, 800#, respectively applicable to the needs of customers at different levels.


8. Inspection

The inspection mainly checks whether the outer diameter and thickness of the pipe meet the standard, whether the surface treatment meets the standard, and whether the welding process meets the standard.


After the above introduction, I believe everyone has a preliminary understanding of the tube rolling machine. ChaoLi Company has been focused on the production of rolling and bending machines for several years. We can work with customers from design to completion to ensure that all technical requirements are met.
