Abstract

The invention relates to an automatic forming method for a refrigerator freezer coaming. The method comprises the steps that a purchased plate is cut into a blocky formed material; according to a design drawing, the cut formed material is trimmed and subjected to edge grinding; plane abrasion is carried out on the initially-formed plate, and the surface smoothness is improved; rolled edge incision and small hole punching are completed for the plate subjected to plane abrasion through a blanking machine; a flanger is adopted for flanging the punched hole; a bending machine is adopted for bending the edge of the treated plate in four passes, and the coaming is formed; a positioning welder is adopted for positioning, shaping and welding the coaming; a repeated spraying way is adopted for spraying protective paint to the welded coaming; and the finished product is generally tested. Production automation can be achieved, and therefore the working efficiency is improved.

Description

technical field [0001] The invention relates to an automatic forming method for a refrigerator-freezer enclosure, which belongs to the field of equipment manufacturing. Background technique [0002] Refrigerator freezers have been produced and used on a large scale in my country. The freezer enclosures in the prior art are composed of four separate panels, the front panel, the rear panel, and the left and right panels, which are connected by connectors. The four panels are manufactured separately. Installed separately, the workers have many operating procedures, the efficiency is low, and it is not conducive to large-scale production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic forming method for refrigerator freezer enclosures with automatic production and reduced manpower. The technical problem to be solved by the present invention takes the following technical solutions to realize: [0004] A...
