The leveling machine is provided with an upper pressing die and a lower pressing die, wherein the upper pressing die is fixed on the push rod of the hydraulic cylinder, the hydraulic cylinder block is fixed on the support frame, and the upper pressing die and the lower pressing die are respectively arranged independently. a cooling water passage, the outlet and the inlet of the cooling water passage are separated from the upper die or the lower die. The ratio of the radius or the center distance of at least the first five rollers from the inlet of the leveler is the same as that of the conventional leveling machine. And the ratio of the radius or center distance of at least the final five rolls from the beginning of the leveling machine to the vicinity of the meandering machine, and it is advantageous that the center distance between the center rolls of the leveling machine is increased. Cool together to prevent corrosion of the tool or tool blank by impurities, and then ensure the quality of the tool or the blank and the hardness of the metallurgical structure to prevent contamination of the cooling oil.
The rolls are made of wear-resistant forged steel. Depending on the width of the machine, each leveling roll is supported by one or more sets of rolls in its length, which minimizes the diameter of the leveling rolls. The distance between the rollers is also reduced. The rollers can be adjusted in the straight direction, so that they often support the full load. The roller surface has a standardized processing finish, but for the machine for leveling the aluminum plate, the surface of the roller is ground and polished. In addition, there is a spiral groove on the roller to collect the foreign ash. The leveling roller is provided with a scraper to scrape off the impurities adhering to the roller, and the scraped impurities are sent to the front of the machine through the channel for collection and removal. .
The leveling machine is a commonly used equipment in sheet metal processing. The setting of the leveling machine depends on the thickness, material and requirements of the strip. The thicker the material, the better the structural rigidity. The smaller the number of rolls, the larger the roll. The greater the power (the width must be), and vice versa. The leveling machine is mainly used to correct the various specifications of the sheet and cut into pieces. This machine is suitable for the leveling of various cold and hot rolled sheets.
Because its operation is convenient and simple, its application range covers many industries such as machinery, metallurgy, building materials, chemical industry, electronics, electric power, light industry, etc., especially in shipbuilding, rolling stock, boiler bridges, metal structure factories and other industries, which is indispensable in production. The necessary products. Roller plate correction machine works multiple times of positive and negative bending of the sheet, so that a variety of original curvature gradually becomes a single curvature, and finally flatten it.
