Problems solved by technology

[0004] After the above-mentioned fuel tank is processed and shaped, it is usually necessary to clean and paint the fuel tank. However, when cleaning, usually only the impurities on the surface of the fuel tank are initially cleaned. The product quality after production of the fuel tank has been reduced, which needs to be improved

Embodiment 1

[0053] Embodiment 1: A production process for fuel tanks, including the following steps:

[0054] S1, cut the plate, cut the plate according to the actual size requirement of the fuel tank, and make the cut plate larger than the actual size requirement of the fuel tank.

[0055] S2, stamping, stamping the cut sheet to form the prototype of a half fuel tank.

[0056] S3, trimming, cut the corners of the four peripheral edges of the punched sheet.

[0057] S4, punching, punching the punched sheet to form a fuel tank port.

[0058] S5, welding, buckle a pair of preliminarily formed fuel tanks together, weld the joints of the two, and weld and fix the angle lugs and the fuel pipe at the same time.

[0059] S6, air tightness test, immerse the formed fuel tank in clean water and observe whether there are bubbles in the clean water to determine the air tightness of the fuel tank.

[0060] S7, cleaning, cleaning the surface of the fuel tank.

[0061] S8, spraying, spray paint on the surface of the...

Embodiment 2

[0069] Embodiment 2: Steps S71, S72, S73 and S74 are all performed in the cleaning equipment.

[0070] Such as figure 1 As shown, the cleaning equipment includes a pair of vertical columns 1, a cross beam 11 is horizontally disposed between the upper ends of the pair of columns 1, and a pickling tank 12, a neutralization tank 13, and a phosphating tank are sequentially disposed below the cross beam 11. 14 and water washing pool 15.

[0071] Such as figure 1 , figure 2 As shown, a sliding seat 2 is horizontally slidably connected to the beam 11, and a supporting seat 3 is hinged on the lower end surface of the sliding seat 2, and a driving mechanism 4 for driving the supporting seat 3 to reciprocate is provided on the lower end surface of the sliding seat 2.

[0072] Such as figure 1 , figure 2 As shown, a mounting seat 5 is provided below the support base 3, a gantry 51 is provided on the upper end surface of the mounting seat 5, and the upper end of the gantry 51 is fixed to the l...

Abstract

The invention discloses a production process for an oil tank and relates to the field of oil tank machining. The production process comprises the following steps of S1, plate shearing; S2, stamping; S3, edge shearing; S4, punching; S5, welding; S6, airtightness detection; S7, cleaning; and S8, plastic spraying. The production process for the oil tank has the following advantages and effects that the oil tank is subjected to acid pickling, neutralizing, phosphating and water washing in sequence to form a layer of phosphating film on the surface of the oil tank, the later adhesive force of a paint film and the corrosion resistant capability of the surface of the oil tank are improved, and therefore, the product quality of the produced oil tank is improved.

Description

Technical field [0001] The invention relates to the field of oil tank processing, in particular to a production process for oil tanks. Background technique [0002] A generator is a mechanical device that converts other forms of energy into electrical energy. The fuel tank is a container for fuel on the generator. [0003] Chinese patent CN108555546A discloses an improved automobile fuel tank processing technology, including S1, unwinding and blanking; S2, fuel tank stamping spot welding; S3, fuel tank bending and straight edge welding; S4, tank flanging and welding; S5, fuel tank End cover forming; S6, fuel tank forming and testing. [0004] After the above-mentioned fuel tank is processed and formed, it is usually necessary to clean and paint the fuel tank. However, when cleaning, only the impurities on the surface of the fuel tank are usually cleaned up initially. The surface of the fuel tank is not thoroughly cleaned, which will affect the quality of the later spray paint. The ...
