Problems solved by technology
However, in the prior art, the production cost of the head is high, which greatly increases the production cost of the oil tank. It uses a stretching process to stretch the head raw material through a hydraulic machine tool, which usually requires a hydraulic machine tool with a tonnage of 500T or more. The stretch forming of the oil tank head is completed, but the tensile damage rate of the hydraulic machine tool is high, and the yield of the stretched head is low. The power is high, which greatly increases the production cost of the head

The invention relates to the oil tank making, and provides an oil tank shell cover making technology with low cost, high production yield, low power, and low power consumption; the technology comprises the following steps: cutting to obtain a round shell cover plate of a needed size, and making a support table die used for placing and processing the shell cover plate; making auxiliary holes in the center of the obtained shell cover plate, welding positioning workpieces in the auxiliary holes, and fixing the shell cover plate on the workpiece support plate; adjusting a pressure core paw so as to enable a periphery of the shell cover plate fixed on a centering piece to be placed in a groove of an arc groove; starting a pneumatic punch to punch the arc groove through a punching head, thus completing a punch stroke for the shell cover plate; bending certain periphery length of the shell cover plate, and repeating the punch stroke of the shell cover plate; gradually carrying out punch strokes for the shell cover plate in sequence until the periphery of the whole shell cover plate is bended; using plugs to seal the auxiliary holes of the shell cover plate completing periphery bending process, thus finishing the shell cover plate.
Description
technical field [0001] The invention relates to the production of oil tanks, in particular to a production process for the head of an oil tank. Background technique [0002] With the rapid development of my country's industry, the domestic oil demand is increasing year by year, and the transportation of various oil products plays an increasingly important role in heavy industry. The market demand for various large tank trucks is increasing. In the actual production process, the oil tank is usually divided into three workpieces, the tank body and the two ends of the head, which are processed and formed separately, and then the three workpieces of the tank body and the two ends of the head are butted together and formed. However, in the prior art, the production cost of the head is high, which greatly increases the production cost of the oil tank. It uses a stretching process to stretch the head raw material through a hydraulic machine tool, which usually requires a hydra...
