Description
Technical Field
The invention relates to a sawing area roller way, in particular to an automatic grouping control method for a middle rod sawing area roller way.
Background
In steel enterprises, the roller ways in the middle rod saw area after cold shearing of special steel are very long, about 67 meters, and are generally divided into six groups according to different lengths of rods, as shown in fig. 1, each group of roller ways is driven by independent power. The length of the finished bar is 4-12 m, wherein the common length is 6 m, and the distance between every two lengths on the roller way cannot be too large if the high-speed production is required to be efficiently met during the roller way transportation process. However, in the aspect of automatic control, in order to meet the requirements of no intersection and logical judgment between two sections of fixed length, the distance between a group of roller ways needs to be ensured between the front and rear fixed length sections during full-automatic control. Therefore, to satisfy the above two requirements at the same time, the length of each set of roller ways should not be too large, and theoretically the best length is consistent with the length of the fixed length. However, the length of the fixed length is an indeterminate value, so that the length of the roller way cannot give a determinate value. At present, the length of the original first group is 12200mm, the length of the original second group is 3400mm, the length of the original third group is 9170mm, the length of the original fourth group is 14400mm, the length of the original fifth group is 14000mm, and the length of the original sixth group is 13970 mm. Obviously, the length of the first group, the fourth group, the fifth group and the sixth group is too long, so that the operation of the roller way in the sawing area cannot follow the production rhythm of the cold shears during automatic control.
At present, two abrasive wheel saws are arranged on a roller way of a middle rod saw area in a front-back mode, the first abrasive wheel saw is located at the head end of an original third group, the second abrasive wheel saw is located at the head end of an original sixth group, the first abrasive wheel saw is a multiple length saw, the multiple length saw is 7.5 meters to 24 meters, and the common multiple length saw is 12 meters. But to current roll table group, the length of former third group is about 10 meters, can not satisfy the condition that multiple length is 12 meters, consequently, the scale baffle needs to set up the front end at former fourth group, when realizing automatic control, will transport the bar to the scale baffle position, former third group and former fourth group roll table must start simultaneously, but because the second abrasive wheel saw is sawing or former fifth roll table has the bar, then there is the bar on the former fourth group roll table, also there is the bar on the fifth group roll table, can not satisfy the interval of guaranteeing a set of roll table between two front and back scale sections, the bar that leads to the upper reaches can not transport first abrasive wheel saw department, saw district production rhythm receives the influence.
