Abstract

The invention discloses a circular radiator box molding method and relates to the technical field of special automotive manufacturing. A molding die utilized in the circular radiator box molding method comprises an upper die and a lower die. The upper die comprises a cylindrical male die and a connecting plate fixed to the male die. The lower die comprises a female die with a circular cavity; the bottom of the female die is fixedly connected to a base plate, and padding bars are arranged under the base plate. The box molding steps include fixing the upper die to a bending punch of a bending machine through bolts, removing the bending punch of the bending machine, debugging and centering the lower die on a workbench and fixing the lower die to the workbench, placing a blank into the circular cavity of the female die, closing the upper die and the lower die of the molding die and then punching the blank, and finally opening the upper die and the lower die to obtain a circular box. Compared with the prior art, the circular box molding method has the advantages that manufacturing cost is lowered greatly since the original bending machine is utilized and an extra punch machine is omitted, and further, the circular box has good quality when punched and formed, and the molding speed, the level of automation and the production efficiency are high.

Description

technical field

[0001] The invention relates to the technical field of special-purpose automobile manufacturing, and relates to a forming method of a circular-arc water tank body. Background technique

[0002] With the development of the national economy, the domestic special vehicle industry has also been greatly developed. The water tank is a functional component that must be configured for medium and long-distance special vehicles, so the demand for water tanks will increase with the increase in the demand for special vehicles. The special automobile water tank is a functional part used to store and withdraw water for cooling the wheel hub. The water tank will be under pressure when storing and withdrawing water. The number of welds and the quality of the welding determine whether the water tank will leak. The traditional tank truck water tank adopts right-angle tailor-welded form, which is gradually eliminated due to its defects such as exposed weld seam, poor weld seam ...
