Problems solved by technology

However, when the outer layer of the metal container 11 is covered with the protective film layer, the metal container 11 cannot be directly attached to the metal fixing piece 12 due to the obstruction of the protective film layer, resulting in the failure of smooth welding.

[0027] refer to figure 2 , a first embodiment of the present invention's combination method of fixing the handle to the sheet metal part covered with a protective film layer, comprising a plate film sticking step 21, a bonding step 22, and a processing step 23.

[0028] refer to figure 2 and image 3 , in the step 21 of attaching the film to the plate, a metal plate 31 is first formed by stamping and forming, and then the metal plate 31 is as image 3 As shown in a semi-air-dried environment, glue is applied on one side of the metal plate 31 with a roller 32, and a protective film layer 4 is pasted on the glued side. In the first embodiment Among them, the material of the protective film layer 4 is selected from one of polyethylene (PE), polyethylene terephthalate (PET), and polypropylene film (OOP). It should be noted that glue can also be applied on both opposite sides of the metal plate 31 , and a layer of protective film 4 can be adhered respectively.

Abstract

The invention relates to a combination method for fixing a handle to a sheet metal part attached with a coating layer. The combination method comprises a plate coating step and a combination step. In the plate coating step, a metal plate is formed in a stamping mode, at least one coating layer is attached to the metal plate, one sheet metal part is cut from the metal plate, and a fixed part is prepared. In the combination step, a lower die and an upper die which is connected with a welding device are prepared, and the upper die is provided with a welding surface and a plurality of pointed convex bodies which are formed on the welding surface. The fixed part is arranged on the lower die, the handle is arranged on the fixed part, finally, the upper die and the lower die are in involution, so that the pointed convex bodies pierce the sheet metal part and the fixed part, and the welding device is started, so that the fixed part is welded on the sheet metal part, and the handle is limited between the sheet metal part and the fixed part.

Description

technical field [0001] The invention relates to a combination method, in particular to a method for combining a handle with a metal material with a sheath layer. Background technique [0002] After the metal container used to store oil products is formed, the outer surface of the container will be coated with a layer of white primer before printing, and then the container will be printed to make the printing color more beautiful, and finally a layer of transparent varnish will be baked. To protect the printing colorant and keep the printing color bright. However, the process of baking clear varnish will cause air pollution, so it is not friendly to ecology. [0003] Now there is another way to protect printing color materials, which is to print on the surface of the metal sheet after stamping and forming, and then apply glue and stick to the metal sheet in a semi-air-dried environment The process of laser coating layer. Finally, the metal plate pasted with the protective ...
