The invention relates to automotive spare parts, in particular to an oil tank provided with a cold machining seal cover. The oil tank comprises a tank body and the seal cover which are made of high-strength cold-roll steel sheets, the outer edge of an opening of the tank body and the outer edge of the seal cover are pressed together through stamping, the stamped outer edges are curled downwards, the section of each stamped outer edge is of a spiral shape, the side, opposite to the seal cover, of the tank body is provided with an oil tank fixing plate, and the sidewall of the tank body is further provided with a pipeline port used for being communicated with the outside. The outer edge of the opening of the tank body and the outer edge of the seal cover are pressed together through stamping, the stamped outer edges are curled downwards, the section of each stamped outer edge is of the spiral shape, and the contact surfaces of the tank body and the seal cover are meshed with each other, so that the seal reliability and connection firmness of the tank body and the seal cover are improved, and the oil tank has a more attractive appearance compared with oil tanks made in a welding mode.
Description
technical field [0001] The invention relates to an automobile accessory, in particular to a fuel tank with a cold-worked cover. Background technique [0002] With the rapid development of national agricultural mechanization, the market has higher and higher requirements for the appearance quality of agricultural machinery fuel tanks, and various agricultural machinery manufacturers have stricter requirements for the appearance quality of new agricultural machinery parts, especially in recent years. The intensity of purchase subsidies has been continuously increased, which has promoted the rapid growth of market demand for agricultural machinery. Agricultural machinery fuel tanks and hydraulic oil tanks are the key components of agricultural machinery vehicles. Previously, they were mainly capable of dissolving fuel and hydraulic oil without leaking oil. There were no specific requirements for appearance, which greatly limited Increase in agricultural machinery sales of agri...
