Embodiment Construction

[0014] In the welding method of the prior art, holes are punched on the outer cover, wherein the punching is only carried out on the metal outer cover, and then the metal plate and the outer cover are welded through the punched holes, thereby welding the metal plate and the outer cover together.

[0015] The inventor has carried out test, such as figure 2 As shown, wherein the metal plate 102 is placed in the installation position (welding position) inside the outer cover 101 when the metal cover 101 is punched, the punching operation does not stop at penetrating the outer cover 101, but continues into the metal plate 102 , that is, the punching operation not only punches the hole 103A penetrating the housing 101, but also proceeds to the corresponding portion of the metal plate 102, forming the hole 103B in the metal plate 102.

[0016] Represent the depth of the hole 103B on the metal plate 102 with d, as figure 2 shown.

[0017] Then, a welding operation is performed in...

Abstract

The invention provides a method for connecting a metal housing (101, 301) with an internally-tangent metal plate (102, 302) arranged in the metal housing (101, 301). The method comprises the following steps: punching a hole (103A) in a pre-determined position on the metal housing (101, 301), and punching a hole (103B) in a position corresponding to the hole (103A) on the metal plate (102, 302), in which the hole (103A) on the metal housing (101, 301) and the corresponding hole (103B) on the metal plate (102, 302) can be punched in the same punching operation; conducting the welding in the hole (103A) in the metal housing (101, 301) and the corresponding hole (103B) on the metal plate (102, 302) when the metal plate (102, 302) is in a pre-mounting state in the metal housing (101, 301), thereby welding the metal plate (102, 302) onto the metal housing (101, 301). The method of the invention can provide a firm and reliable connection when the metal plate (302) is made by powder-sintering.

Description

technical field [0001] The invention relates to a method of welding a metal plate inside a metal housing and a metal housing with a metal plate inside produced by the method. More specifically, the metal plate is a powder sintered metal plate. More specifically, the metal housing is the compressor housing of a refrigerator / refrigerator. Background technique [0002] In some industrial applications, it is necessary to weld an inboard metal plate in the cylindrical metal shell, thereby dividing the inner space of the shell into two parts. For example, some refrigerator / refrigerator compressors have image 3 The structure shown includes a metal plate 302 disposed in such a metal casing (compressor housing) 301 . figure 1 Such a housing 101 and a metal plate 102 arranged therein are shown schematically in general. The sheet metal 102, 302 is traditionally manufactured using casting methods. The metal plates 102, 302 and the housing 101, 301 are welded together by welding at...
