Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0016] figure 1 and figure 2 The shown oil tank car arc water tank forming mold includes an upper mold and a lower mold installed on a bending machine. The upper mold includes a cylindrical punch 1 and two sets of connecting plates fixedly connected to the punch 1. This The punch 1 in the embodiment is a hollow cylinder, and two sets of connecting plates are arranged along the axial direction of the punch 1, and each set of connecting plates is composed of two oppositely arranged ear plates 2, and each ear plate 2 is provided with a screw. Hole 2-1; When installing the upper mold, use bolts to connect the four screw holes 2-1 on the ear plate 2 with the process holes on the bending punch of the bending machine, so as to fix the upper mold on the bending machine. The upper and lower molds of the bending punch include a concave mold 3 with an arc-shape...

Abstract

The invention discloses a forming die for the arc water tank of an oil tank truck and relates to the technical field of special automobile manufacturing. The forming die comprises an upper die and a lower die. The upper die comprises a cylindrical male die and a connecting plate for being connected to the bending male die of a bending machine. The connecting plate is fixedly disposed on the male die and provided with a screw hole. The lower die is mounted on the working table of the bending machine. The lower die comprises a female die with an arc cavity. A base plate is fixedly connected to the bottom of the female die. Filler strips are disposed below the base plate. Compared with the prior art, the forming die has the advantages that the original bending machine is utilized, an additional punching machine is not needed, manufacturing cost is lowered greatly, the punched and formed arc water tank is good in quality, and the forming die is fast, high in automation level and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of special-purpose automobile manufacturing, and relates to a molding die for a circular-arc water tank body. Background technique [0002] With the development of the national economy, the domestic special-purpose vehicle industry has also been greatly developed. The water tank on the special-purpose vehicle is a functional component that must be equipped with medium and long-distance oil trucks, so the demand for such water tanks will increase with the special-purpose vehicle increase with increasing demand. This type of water tank is a functional part used to access water for cooling the 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 water tank adopts the form of right-angle tailor welding, which is gradually eliminated due to its defects such as exposed weld seam...
