When purchasing a semi-trailer, price is one aspect, but the quality of the semi-trailer is more worrying. For this reason, many customers will compare prices and visit several trailer factories to see the scale of the factory and the level of trailer manufacturing, and then comprehensively decide which trailer to buy. Good equipment is one of the factors that determine the quality of a semi-trailer. Without further ado, the following editor has compiled some equipment that can reflect the factory’s trailer production level. Drivers and friends can use it as a reference when purchasing.
The three most necessary equipment for producing trailers are: underwater cutting machine, automatic submerged arc welding and shot blasting machine. These three major items directly reflect the production level of the trailer factory. The following are the functions of these three major items.
Automatic submerged arc welding: ensure uniform welding of the beam Automatic submerged arc welding Automatic submerged arc welding is mainly used to weld the beam. It uses seamless and dead joint welding technology to weld the beam evenly at one time. It can effectively avoid the occurrence of beam welding and broken beams caused by manual welding and multiple nodes.
The price of automatic submerged arc welding is only tens of thousands of yuan for small ones and more than 100,000 yuan for large ones. In Liangshan, most trailer factories of a certain scale have this equipment. If the trailer factory you are investigating does not even have automatic submerged arc welding, you must be careful.
Underwater cutting machine: Prevent changes in the rigidity of steel Underwater cutting machine Underwater cutting machine is mainly used to cut steel. Compared with the flame cutting used by some small factories, the temperature of the arc of the underwater cutting machine to penetrate the steel is relatively low, which can effectively reduce the changes in the rigidity of the steel due to annealing, and the cutting is more beautiful than manual cutting.
Flame cutting used by small factories, high-temperature flame steel annealing will cause changes in the carbon content inside the steel, which will reduce the performance of the steel. The advantages of underwater cutting machines are obvious, but the price is also relatively expensive, about 500,000 yuan. There are many manufacturers of underwater cutting machines and automatic submerged arc welding in Liangshan.
Shot blasting machine: Strengthen the beam to prevent the beam from breaking, blasting, and paint falling off. Shot blasting machine The main function of the shot blasting machine is to strengthen the beam and protect the trailer beam from problems. It is mainly reflected in the following aspects:
- Change the rigidity of the steel damaged by the flame cutting, change the structure of the steel to make the rigidity of the entire beam evenly distributed, so as to avoid the tragedy of beam breakage, cracking or cracking.
- The shot blasting machine can effectively grind various parts of the beam, avoid dead corners that are not polished, make the paint spraying more uniform, and prevent the beam from falling off and rusting in the later stage.
Shot blasting machines are very expensive, with a price of about 3 million, which is not affordable for ordinary small factories. Manufacturers that can equip shot blasting machines can be said to be strong.
The above is the main equipment for semi-trailer production, which can be used as a reference when friends choose semi-trailer manufacturers. I wish everyone can choose high-quality products with good quality and low price.
