The invention has the beneficial effects that: in the pressing process, the stainless steel magnetic net is extruded and pressed with the guide post on the aluminum pot to deform, and a large transverse stress is arranged between the mesh hole and the guide post to prevent the stainless steel magnetic net from falling off from the bottom of the pot.

Description

Stainless steel magnetic conduction net, aluminum pot for electromagnetic oven and pot bottom processing technology of aluminum pot

Technical Field

The invention relates to an improvement in the field of aluminum pan bottoms for electromagnetic ovens.

Background

When the aluminum pot in the prior art is used on the induction cooker, because the aluminum pot adopts aluminum which is not capable of generating magnetic induction heat for the induction cooker, the aluminum pot used on the induction cooker needs to be added with a stainless steel net at the bottom of the pot.

The embedding of stainless steel mesh is divided into two modes, one is to slot and embed the stainless steel mesh at the bottom of the aluminum pot, and the other main stream is to directly press the stainless steel mesh at the bottom of the aluminum pot through a punching machine, for example, the bottom mesh of patent number 200910099714.1 needs to be provided with an inserting edge, and the inserting edge is extruded into the bottom of the aluminum pot to finish the punching. However, the stainless steel mesh in this way has a general connection strength, is relatively complicated to produce, and cannot be used on a stainless steel mesh with arc mesh holes.

Disclosure of Invention

In order to overcome the defect of low connection strength of the stainless steel magnetic conduction net, the invention provides the stainless steel magnetic conduction net and a processing technology of the bottom of the aluminum pot for the induction cooker.

The technical scheme for solving the technical problem is as follows: the stainless steel magnetic conductive net comprises a net body, wherein net holes are formed in the net body, and each net hole is formed by two straight edges with the same included angle and an arc line connecting the two straight edges; and the included angle of the net body, which is adjacent to the net eye hole, is provided with a bending convex tip.

Further, the highest end of the bent convex tip is an included angle.

Further, the mesh holes are arranged in rows in sequence, and adjacent rows are staggered by half a bit.

The stainless steel magnetic conduction net comprises a net body, net eye holes are formed in the net body, and the net eye holes are formed by enclosing two straight edges with the same included angle and an arc line connecting the two straight edges; the included angle of the net body, which is adjacent to the net eye hole, is provided with a bending convex tip; the stamping process comprises the following steps:

the method comprises the steps that firstly, a stainless steel magnetic conduction net is placed on a planar aluminum pot bottom, and a bent convex tip part faces the aluminum pot bottom;

and secondly, punching the stainless steel magnetic conduction net into the bottom of the aluminum pot, extruding the aluminum pot body out of the convex columns corresponding to the mesh holes, deforming the net body of the stainless steel magnetic conduction net in the punching process, and clamping the convex columns to press and deform towards the included angle to drive the convex columns to deform into a forming seam until the mesh holes and the convex columns on the net body become shuttle-shaped structures on the finished product.

Further, the highest end of the curved convex point part on the net body is an included angle.

Further, the mesh holes on the net body are sequentially distributed in rows, and the adjacent rows are distributed in a staggered half unit mode.

The invention also relates to an aluminum pot for the electromagnetic oven, which comprises an aluminum pot body, wherein the bottom of the aluminum pot body is provided with a stainless steel magnetic conduction net, the meshes of the stainless steel magnetic conduction net are shuttle-shaped, convex columns are arranged in the meshes, and the surfaces of the convex columns and the lower end surface of the stainless steel magnetic conduction net are in a plane; the outside of one arc side of the shuttle-shaped mesh is provided with a forming seam.

The invention has the beneficial effects that: in the pressing process, the stainless steel magnetic net is extruded and pressed with the guide post on the aluminum pot to deform, and a large transverse stress is arranged between the mesh hole and the guide post to prevent the stainless steel magnetic net from falling off from the bottom of the pot.
