This production line is a special equipment for the production of longitudinally welded pipes in metallurgy, construction, transportation, machinery, vehicles and other industries. It uses steel strips of certain specifications as raw materials, and produces square pipes of required specifications through cold bending and high-frequency welding methods. Rectangular tube etc. The production line adopts mature, reliable, complete, economical and applicable advanced technology and advanced equipment to ensure that the product’s physical quality, cost, and various consumption indicators reach a relatively advanced level. The products produced have a strong competitive edge in quality and price. Competitiveness.
The new direct squaring process has the following advantages over the ordinary direct squaring process:
(1) The load of the unit is low, which greatly reduces the time for changing rolls.
(2) The axial force and lateral wear during forming are eliminated, which not only reduces the number of forming passes to ensure product accuracy, but also reduces power loss and roll wear. Since there is no need to disassemble the roll, the damage to the equipment is further reduced.
(3) Combined rolls are used for multiple shifts, and the rolls on the roll shaft are opened and closed through the mechanism, so that a set of rolls can produce dozens of specifications of square and rectangular tubes, which can greatly reduce the reserve of roll spare parts and reduce the cost of rolls by 80 %, in order to accelerate capital turnover and shorten product development cycle.
(4) This method has a better shape at the corners of the section, a smaller radius than the inner arc, straight edges and a more regular shape.
(5) The operator does not need to climb up and down, and can control the machine through buttons or remote control, which is very safe.
(6) Greatly reduce labor intensity.
