Problems solved by technology

[0004] The purpose of the present invention is to provide a brazing method for oil collector and filter, which solves the problems that the traditional welding method is difficult to operate, the product is not beautiful in appearance, and needs to be galvanized after welding, so as to avoid the decline in the quality of the oil caused by the peeling off and peeling of the zinc layer

Embodiment Construction

[0032] Let's take the processing of 474Q oil filter as an example:

[0033] First select the No. 10 cold-rolled steel plate, and use the traditional stamping process to form or press riveting to make the flange 1, the support piece 3, and the filter body 4 single parts, and use the welded pipe to make the oil pipe 2 through the necking forming process. Body parts, and then assemble them together as follows:

[0034] A. Use a heading machine to press-fit the flange 1 to one end of the oil pipe 2, and ensure that the fit gap is between 0.01 and 0.03mm;

[0035] B. Use a heading machine to press-fit the filter body 4 to the other end of the oil pipe 2, and ensure that the fit gap is between 0.01 and 0.03mm;

[0036] C. Place the support piece 3 on the outer wall of the oil pipe 2 close to the filter screen body 4, and spot weld the process hole at the lower end of the support piece 3 with a pressure arc welding machine, so that the filter screen body 4 and the oil pipe 2 are clo...

Abstract

The invention is an engine oil suction filter soldering assembly method, which uses traditional pressing technics forming or rivet pressing technics to produce a flange plate (1), a supporting piece (3) and a filtering net (4), use a weld seam pipe to produce an oil pipe (2) by the tube sinking forming technics, then arrange the flange plate (1) and the filtering net (4) at the two ends of the oil pipe (2), the supporting plate (3) the outer wall of the oil pipe 2 close to the filtering net 2, then, lay the installed engine oil suction filter in an air protecting braze welding furnace stably to proceed braze welding in furnace. By the method in the invention, the prepared product not only has good and appearance and quality, even welding line, fixed welding, and is beautiful, but also doesn't need galvanizing, which prevents after effect of the zinc layer peeling off and improves the whole quality of the product.

Description

technical field [0001] The invention relates to a welding method for an engine oil filter, in particular to a brazing method for an engine oil filter. Background technique [0002] At present, the welding process of the oil filter mainly adopts the traditional welding process methods, such as CO2 gas shielded welding, artificial arc welding and so on. These welding methods are all controlled by the operator's technical level and proficiency. The consistency of the welding is poor, the welding gap is large, the welding seam is uneven, and the accumulation of the welding lump will affect the assembly and need to be polished; it is easy to weld the oil pipe through and fail to meet the air tightness requirements; the welding seam is uneven and inconsistent in size, which affects the appearance; The consistency of welding strength is poor, and galvanizing treatment is required after welding. At the same time, because it is a manual operation, the labor intensity of the operato...
