Embodiment Construction

[0014] A specific embodiment of a tailor welding method between sheet metal parts according to the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] A tailor welding method between sheet metal parts according to the present invention, the steps are:

[0016] 1) if image 3 As shown, when punching the first sheet metal piece 1 that includes the appearance surface A, four inwardly bent splicing tabs 11 (splicing tabs 11 ) are punched out at the edge of the appearance surface A of the first sheet metal piece 1. The number depends on the actual situation, the splicing lug 11 is located in the hidden surface B), and, when designing the stamping die of the first sheet metal part 1, it should be ensured that the outer surface of the splicing lug 11 does not exceed the appearance surface A The end surface 101 on the corresponding side of the splicing lug 11 forms a transitional connection portion 111 at the junction of the app...

Abstract

The invention discloses a tailored-welding method for sheet metal parts, which can hide spots left during welding. The tailored-welding method comprises the following steps: 1) during stamping of a first sheet metal part comprising an appearance surface, stamping at least one inwardly-bent splicing convex sheet at the edge of the appearance surface of the first sheet metal part, and stamping splicing grooves which are in one-to-one correspondence with the splicing convex pieces on the first sheet metal part at the corresponding edge of a second sheet metal part during stamping of the second sheet metal part spliced with the first sheet metal part; and 2) during splicing, placing the splicing convex pieces on the first sheet metal part in the splicing grooves of the second sheet metal partin a one-to-one correspondence mode, and then welding the bottom walls of the splicing grooves of the second sheet metal part together with the end parts of the splicing convex pieces on the first sheet metal part to form welding connecting parts, so that the first sheet metal part and the second sheet metal part are spliced together. The tailored-welding method is particularly suitable for products which are made of decorative plates such as stainless steel and cannot damage the appearance surface during welding.

Description

technical field [0001] The invention relates to a connection method between sheet metal parts, in particular to a tailor welding method between sheet metal parts. Background technique [0002] As we all know, sheet metal products need to be connected together at the adjacent edges formed after stamping to form products such as shells. At present, welding is used for connection, and surface treatment is usually required after welding. However, for some stainless steel products that require high appearance quality, the surface cannot be treated after connection, so that the spots left on the edge of the appearance surface during welding will affect the overall appearance quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tailor welding method between sheet metal parts that can hide the scars left during welding. [0004] In order to solve the above technical problems, the technical solution adopted in the...
