Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0036] Such as Figure 1-4 shown.

[0037] A stainless steel corrugated plate, according to the number of corrugations can be divided into such figure 1 A wave of corrugated plates as shown, such as figure 2 The two-wave corrugated plate shown, as image 3 The three-wave corrugated plate shown, as Figure 4 For the four-wave corrugated board shown, the thickness of the corrugated board is generally 1.0-2.5mm. It can be formed by continuous roll cold bending, and the rolls are continuously bent and deformed pass by pass, and the upper and lower rolls are used in pairs during the deformation process, and the guide vertical rolls and side vertical rolls are used at the same time.

[0038] The specific manufacturing process of the present invention is described below by taking four corrugations as an example:

[0039] (1) Slitting strip steel: Cut th...

Abstract

The invention discloses a continuous roll cold bending forming method for stainless steel corrugated plates, which is characterized in that: continuous roll cold bending forming is adopted to produce roll-bent deformation pass by pass continuously by using a roll; upper and lower roll opposite rolling forming is adopted in a deformation process; and a guide vertical roll and a lateral roll are adopted at the same time. The method has the advantages of high product consistency, stable quality, unlimited length, reasonable straight angle change and arrangement and long equipment service life.

Description

technical field [0001] The invention relates to a manufacturing method of profiles, in particular to a manufacturing method of a stainless steel waterstop, in particular to a continuous roll cold bending forming method of a stainless steel corrugated plate. Background technique [0002] As we all know, stainless steel corrugated plates are widely used in compensators, among which corrugated compensators are more commonly used, mainly to ensure the safe operation of pipelines, compensate and absorb the axial, transverse and angular thermal deformation of pipelines, and the expansion and contraction of corrugated compensators to facilitate the installation of valve pipelines And dismantling, absorbing equipment vibration, reducing the impact of equipment vibration on pipelines, absorbing the deformation of pipelines caused by earthquakes and ground subsidence, these functions are played by the main corrugated plate. At present, the commonly used processing method of stainless ...
