Section steel manufacturing system and method based on BIM and CAM technologies

Abstract

The invention discloses a section steel manufacturing system and method based on BIM and CAM technologies. The system comprises information transmission of a BIM design end and a CAM production end, the BIM design end comprises a design drawing manufacturing module and a section steel software processing module which are connected, the CAM production end comprises a controller and a processing device which are connected with each other, the section steel software processing module is connected to the controller through an Ethernet bus, and the processing device is connected to a welding installation end. The system is reasonable in structure and easy to use, the information transmission between the BIM design end and the CAM production end is achieved, informatization transformation is conducted on existing equipment, the existing equipment can accept globally optimized production management arrangement, and only necessary safety maintenance personnel are needed from BIM design to production forming in section steel machining. The information transmission is adopted in the whole process, and the purpose that small-batch and large-type building projects can be produced in an industrialized mode is achieved.

Description

technical field [0001] The invention relates to the technical field of profile processing, in particular to a profile manufacturing system and method based on BIM+CAM technology. Background technique [0002] At present, BIM has entered the key projects of the national science and technology support plan. At present, CAM technology is very mature, and the efficiency in CNC cutting and blanking pipes, profiles, plates, and even steel bars is already very high. The main difficulty restricting the application of BIM at present is how to change from traditional How to automatically provide BIM data to CAM software, and provide it to CNC processing equipment through intelligent nesting has entered the exploration stage in China. Such as figure 1 As shown, currently in China, the design institute provides BIM or CAD models for the processing of profiled steel structures, and the construction unit organizes personnel to turn over the samples and deepen them, and process them into ...

AI Technical Summary

Problems solved by technology

[0004] 1. Re-deepen the mold turning (a lot of manual work);

[0005] 2. Statistical engineering quantity (a large amount of labor);

[0012] 2. The purpose of steel structure processing is for welding. The national standards for welding grooves are very complicated, but steel structure processing workers and sample-turning technicians do not know much about welding, and the information is out of touch in the process of transmission.

[0013] 3. In the past, there was no concept of globalization in the process. The better ones were divided into batches and components according to the lifting weight, and the production plan was formulated, resulting in more residual waste in each processing, lower material utilization rate, and more waste.

The repetitive processing path is messy, and the power gas consumption is more wasteful

[0014] 4. The processing trajectory of profiles is very complicated. The mechanical form of processing equipment requires multi-axis linkage. Only robots can do it, but robots are easy to program for batches. For profile processing that is different for each part but requires programming and teaching Generally speaking, the task of path planning is very cumbersome, and the processing preparation time far exceeds the processing time

[0015] Existing equipment can solve the mass production of large quantities and few types, but for more and more personalized designs, it is impossible to provide standardized products
