Embodiment Construction
[0015] Illustrate the specific embodiment of the present invention in conjunction with accompanying drawing, a kind of manufacturing method of sheet metal oil sump hand workpiece of the present invention, comprises the following steps:
[0016] Step 1. Carry out horizontal cutting between the deep oil storage chamber 3 and the shallow oil storage chamber 1 of the oil pan. The vertical distance between the position of the cutting line and the bottom surface of the shallow oil storage chamber 1 is between 0 and 25 mm. In this embodiment The cutting line is close to the lower end surface of the lower bottom surface of the shallow oil storage chamber 1;
[0017] Step 2. Weld the lower end of the cut shallow oil storage chamber 1 casing to the upper end of a connecting plate 2, move the cut deep oil storage chamber 3 casing to the rear end of the oil pan for a distance, and then place its upper end Welded on the lower end of the connecting plate 2, the lower end of the deep oil sto...

Abstract
The invention relates to a manufacturing method for an oil pan, in particular to a manufacturing method for a metal plate oil pan handwork part. The manufacturing method aims at solving the problems that when an existing oil pan handwork part is manufactured, the oil containing capacity of an original oil pan is reduced, and oil leakage is easily generated. The oil pan comprises a shallow oil storage cavity and a deep oil storage cavity. The manufacturing method for the metal plate oil pan handwork part includes the steps that the position, between the shallow oil storage cavity and the deep oil storage cavity, of the oil pan is horizontally cut, the lower end of a cut shallow oil storage cavity shell is welded to the upper end of a connecting plate, the upper end of a cut deep oil storage cavity shell is welded to the lower end of the connecting plate, the position of the cut deep oil storage cavity shell deviates to the rear end of the shallow oil storage cavity shell, and a plurality of through holes are formed in the connecting plate to enable the cut shallow oil storage cavity and the cut deep oil storage cavity to be communicated. The machining method for the oil pan is simple, and the application range is wide.
Description
technical field [0001] The invention relates to a method for manufacturing an oil pan, in particular to a method for manufacturing a sheet metal oil pan hand workpiece, and belongs to the technical field of automobile oil pan processing. Background technique [0002] During the implementation of the new car factory project, the oil pan often interferes with the drive shaft or the Yuanbao beam. At this time, even if the new design is completed immediately, it is difficult to quickly respond to the parts due to the constraints of the mold opening cycle. At this time, it is often necessary to make the oil pan manual work, that is, to modify the crude oil pan, to realize the physical installation of the engine in the depot. At present, the cutting and welding method is generally used, that is, based on the existing oil pan body, cutting off the part where the oil pan interferes with the chassis, and then smashing the sheet metal into a certain curved surface, and welding it wit...
