A Processing Technology of Stainless Steel Corrugated Plate with Improved Head Structure

Abstract

The invention discloses a stainless steel corrugated plate with an improved head structure, which comprises a flat body, a plurality of corrugated strips equally spaced parallel to the top surface of the flat body and higher than the top surface of the flat body; the radial section of the corrugated strips is wavy , formed by a crest in the middle and two symmetrically distributed troughs adjacent to both sides of the crest, including the left trough section, the middle peak section and the right trough section in turn; the two troughs are connected to the top surface of the plate body , and form a wave-shaped inner cavity opening toward the bottom surface of the plate body with the crest; the axial ends of the corrugated strip are closed and close to the two side edges of the plate body respectively. The invention also provides a processing technology with simple procedure, convenient operation, high degree of automation and high processing precision, and can produce corrugated plates with beautiful structure, high strength and large bearing capacity. In terms of performance, it has been greatly improved; it can avoid the overlapping welding of multi-layer plate thickness, and effectively prevent the phenomenon of weld leakage.

Description

technical field [0001] The invention relates to a corrugated plate, in particular to a stainless steel corrugated plate with an improved head structure and its processing technology, belonging to the production technical field of stainless steel corrugated plates. Background technique [0002] The common corrugated plate structure is formed by rolling corrugations on the steel plate. These corrugations completely change the mechanical properties of the steel plate. Small transverse corrugations can improve the local stable bearing capacity of the steel plate, enhance the longitudinal bending stiffness of the structure, and highlight the structural shell. Stress characteristics. Due to the advantages of high strength and large force, corrugated plates are more and more widely used in industry. Therefore, the roof and floor of stainless steel urban rail vehicles generally adopt the form of stainless steel corrugated plates. [0003] However, for the stainless steel corrugate...

Problems solved by technology

[0004] At present, the traditional simple structure of the head molding die is used to stamp the individual head, and the direct flattening method is adopted. Although the structure of the head is simple, the pressing effect is not good.

like figure 1 As shown, the seal head obtained by pressing with the traditional process has the disadvantage that the left lug 10 and the right lug 20 are inconsistent, that is, it is difficult to form a symmetrical effect; The structure of the head directly affects the connection with other components, resulting in poor sealing of the weld seam during welding, and the weld seam is extremely prone to rain leakage during use; and the metal distribution at the head at both ends of the corrugation is uneven, and there are multi-layer plate thickness overlapping welding Defects
