Cold roll forming and virtual manufacturing system based on CATIA

Abstract

The invention belongs to the field of a virtual manufacturing system for constructing the process of cold bend forming by using CATIA software. Aiming the problem that the prior roller can only be used after field modification, the invention uses the virtual function of the CATIA software to develop the cold bend forming virtual manufacturing system. The system uses V-B language to compile and is connected with the CATIA software, and comprises a general platform, a part generating program calling platform and an assembly platform, wherein the general platform is a general system interface, the part generating program calling platform can call programs of various rollers, and a three-dimensional drawing and an engineering drawing are showed on the CATIA software after data input. The assembly platform virtualizes the rolling process after a rolling sequence list and space coordinates during the rolling of the rollers are inputted, analyzes and amends the stress-strain of the rollers during rolling, evaluates and amends the rolling quality and finally outputs the qualified roller data by data stream. The proposal comprises the steps: 1) establishing the general platform; 2) establishing the part generating program calling platform; 3) establishing the assembly platform; 4) establishing a roller part virtual module of the part generating program calling platform; 5) establishing a rolling process virtual module; 6) establishing a stress-strain analyzing module; 7) establishing a rolling quality analyzing and amending module; and 8) establishing a roller manufacturing data stream output module.

Description

Technical field: [0001] The invention belongs to the field of using CATIA software to construct a virtual manufacturing system for cold-bending forming process, and is to construct a virtual manufacturing system that virtualizes the entire rolling process and proposes a modification plan according to the designed roll parameters and spatial positions. Background technique: [0002] Cold-formed steel or longitudinally welded pipe is a cold-rolled section commonly used in national economic construction, and the tool for rolling cold-formed steel or longitudinally welded pipe is a roll. The forming of cold-formed steel or longitudinally welded pipe is finally formed through the extrusion deformation of a multi-roller system. Each roll system constitutes the pass pattern of the stand, and the design and manufacture of the pass pattern play a vital role in the forming quality of the profile. The current pass design generally adopts the method of combining continuous deformation ...
