Embodiment Construction

[0017] In order to save materials and reduce costs, the processing method to be provided by the present invention is not to use a circular sheet to stretch and form it, and then wash away the bottom to form a loop, but to directly weld the strip to form a loop according to the specific requirements of the heightened loop size. , after bulging and starting, and then curling. With reference to the accompanying drawings, specifically include

[0018] 1) Slicing, cutting the plate into strips as required.

[0019] 2) Seam welding to form a circle, the strip-shaped steel material is rolled into a circle and then seam-welded to form a cylindrical circle 3 .

[0020] 3) Bulging starting stage, in the technical field, welded into circles with strips, when stretching and bulging, because there is no effect of the anchor shape played by the bottom, it is easy to cause wrinkling when bulging is starting and deformation. In this regard, the inventor improves the existing bulging starti...

Abstract

The invention relates to a processing method for heightened rings of cookers, which comprises the processes of slicing, seam welding to form rings, bulging to form levels, curling and polishing, etc. The invention is technologically characterized in that a cone upper mould and a concave lower mould which is matched with the cone upper mould are used when the cooker is bulged to form the levels; the upper mould and the lower mould that are driven by a power machine are matched mutually to fix the cylinder rings and bulge the upper edge of the cylinder ring to form the levels by squeezing polyurethane; the processing method for the heightened rings of the cookers omits the defect of needing to remove bottom sheets in the prior art and has the advantages that the processing method for the heightened rings of the cookers simplifies the process flow, saves materials and improves the efficiency, etc.

Description

technical field [0001] The invention relates to a hardware processing technology, in particular to a processing method for a stainless steel heightening ring used for increasing the volume of a pot. Background technique [0002] Steamers and baking pans are commonly used kitchen utensils in the kitchen. Sometimes there are many things to be steamed and baked, so it is necessary to temporarily increase the capacity of the pot. The raised ring is specially designed to solve this problem. When using, you can use several or one at the same time according to the actual situation to meet the needs of steaming and roasting. The raised ring is practical and easy to use. At present, manufacturers who produce heightening rings generally use stainless steel plates or stainless iron plates to punch them into round sheets, and then stretch them through hydraulic presses, then trim the edges, bulge and start, and then use a punch to punch the bottom to form rings. Rolled. The heighten...
