Problems solved by technology

However, in the current actual production process, workers still rely on manual calculations for blanking. Workers blank profiles and pipes according to their own work experience. In this way, a simple solution can be obtained quickly, but this solution is often not ideal. The utilization rate of materials is not very high
In addition, manual calculations are also prone to calculation errors. The cutting process is time-consuming and laborious, which affects the enthusiasm and efficiency of workers.

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with specific embodiments.

[0020] A kind of large-scale pipeline blanking method of the present invention as shown in accompanying drawing, comprises the following steps:

[0021] (1) Data of m kinds of raw materials used as blanking base material (L j ,b j ) and the data of pipeline parts required in n types of construction drawings (l i , d i ) into the CNC library, and arrange the order of m raw materials in order of length from small to large (L 1 ,b 1 ),(L 2 ,b 2 ),...,(L m ,b m ) and the sequence of n parts (l 1 , d 1 ),(l 2 , d 2 ),...,(l n , d n ). Said (L j ,b j ) represents the length and quantity of raw materials, the (l i , d i ) indicates the length and quantity of parts required.

[0022] (2) According to the number of raw materials in the database and the number of parts remaining to be processed, calculate in turn all the blanking schemes A={A 1 ,A 2 ,....

Abstract

The invention discloses an intelligent trepanning method for a large oil and gas module pipeline. The heuristic algorithm is adopted to control the pipeline discharging process, the optimal discharging scheme on each raw material is obtained through calculation, and then the optimal discharging scheme is used for discharging as much as possible. According to the scheme, the utilization rate of theraw materials can be increased as much as possible, the calculation time can be greatly shortened, the difficulty of manual calculation is relieved and the discharging efficiency of a large pipelineis improved.

Description

technical field [0001] The invention relates to an intelligent nesting method for large-scale oil and gas module pipelines, which is suitable for nesting large-scale pipelines. Background technique [0002] For the current blanking problem, the most used method in the machining industry is to discharge some relatively large parts on the raw material for blanking first, and then allocate some small parts for blanking, so as to improve the accuracy of the base material as much as possible. utilization efficiency. However, in the current actual production process, workers still rely on manual calculations for blanking. Workers blank profiles and pipes according to their own work experience. In this way, a simple solution can be obtained quickly, but this solution is often not ideal. The utilization rate of materials is not very high. Moreover, calculation errors are also prone to occur during manual calculations. The blanking process is time-consuming and laborious, which aff...
