The roll forming machine is used to shape sheet metal. The process is to pass a sheet of metal through a series of continuous hardened steel rollers, shaping the metal into a finished shape, station by station, as it passes through these rollers. This method allows the sheet to be formed quickly into a variety of shapes. From simple ripples to long shapes that are completely closed. The metal is shaped gradually to prevent too much stress in a particular area. Because forming is done by stretching, in many cases, the rolled sheet metal is mechanically produced and mass production is possible. Then what are the advantages of roll forming machines over traditional presses?
1. Roll forming machine is more advantageous than the traditional pressing molding method
The traditional molding method has some shortcomings, so the rolling molding machine is used for rolling molding. The material distribution system lays the raw material on the traction steel belt, which rotates to transfer the raw material of the same thickness to a pair of opposite rollers for rolling molding. roll forming has the characteristics of low power consumption, low noise, low pollution, high efficiency and high flexibility, etc. roll forming machine has incomparable advantages in manufacturing, transportation, installation and other aspects of the traditional press.
2. Function division of roll forming machine
roll forming machine can be divided into distribution area, pressure exhaust area, pressing area and pressure release area according to the function. In the process of pressing, the force of the steel belt is mainly the line pressure between the two rollers and the tension generated by the tension of the steel belt. This molding method does not cause the strip to deform due to yield. Compared with the belt, the steel belt has the characteristics of high hardness, high tensile strength, high yield strength and low elongation.
3. Excellent mechanical properties of roll forming machine
The frame of the roll forming machine is composed of an upper beam, lower beam and upper frame. The main body of each part is high-strength structural steel. The upper and lower beams are plate structure, simple structure, and lightweight. Rolled or forged steel plates can be used to avoid the potential risks of using large castings.
The steel strip used in the roll forming machine has excellent hardness, tensile strength and yield strength, and its excellent mechanical properties can ensure that the pressure is maintained throughout the forming area. The steel strip directly contacts the brick surface, and the surface condition of the working surface will directly affect the surface quality of the finished plate. The mechanical properties and surface flatness of steel strips are obviously better than those of steel strips. Excellent flatness can ensure the reliable operation of the roller press and the uniform thickness of pressed products.
The frame is the main bearing part of the press, so strength and stiffness should be considered in the design. Sufficient strength is the guarantee of press safety and reliability, and the rigidity of the frame will directly affect the geometric precision of the molding products. Reasonable frame design should not only meet the mechanical properties of the frame but also fully consider the convenience of manufacturing technology and installation and transportation.
