Saw cutting method of square pipe saw cutting machine

Abstract

The invention discloses a saw cutting method of a square pipe saw cutting machine. The saw cutting method includes the following steps that firstly, a task list of a list form is input in a control system of the saw cutting machine, wherein the task list includes a production piece task list, and the production piece task list comprises end portion angles and lengths of the two ends of each production piece and the length and width size information of square pipes; secondly, the control system reads and analyzes all parameters of the production pieces in the production piece task list and conducts simulation cutting, wherein according to the principle of analysis, the angles are analyzed before the lengths; thirdly, various simulation cutting sequences are achieved after analysis and simulation are completed, and the primary optimal simulation cutting sequence with the highest square pipe utilization rate is selected; and fourthly, the raw material square pipes are subjected to saw cutting through the square pipe saw cutting machine according to the primary optimal simulation cutting sequence. The saw cutting method is suitable for cutting of the various square pipes of different specifications at the same time, the utilization rate of each raw material square pipe is increased, the after-product length is decreased, and therefore cost is reduced.

Description

technical field

[0001] The invention relates to the field of sawing machines, in particular to a sawing method for a square pipe sawing machine. Background technique

[0002] The sawing of the existing square tube generally has two forms, one is to saw the raw material square tube at right angles and cut it into multiple square tubes with right angle ends at both ends, and the other is to cut the raw material square tube obliquely into multiple two The end of the square tube is an acute-angled end. The sawing of the first type of square tube is very simple, while the second type of square tube has an acute-angled end, so it needs to be used in large quantities in some special occasions and industries, such as the field of rack production The second type of square tube with different lengths and different end angles needs to be used in the production of the passenger car body frame of an automobile. However, the current method of miter cutting can only cut square tubes of the...
