Problems solved by technology

However, most of the current cooling bed distribution methods are pre-set through the operation interface. In actual use, especially after the production line is overhauled or the rolling specification is changed, due to the speed of the rolled piece, the length of the multiplier and the cooling bed The speed needs a process of groping to find a reasonable setting range. In this process, if there is a slight carelessness, the double ruler will hit the sawtooth-type step-type cooling bed and the movable teeth will cause the cooling bed to be chaotic, which will seriously affect Production

Embodiment 1

[0057] Step S101 sets the rolling parameters, and this step sets the length L=62 meters, the distance L1=31 meters between the first detector 1 and the second detector 2, the operating parameters of the steel loading device and the step-by-step cooling bed 7 operating parameters, wherein the distance L1 between the first detector 1 and the second detector 2 is set during debugging, and there is no need to set it again after the setting is completed;

[0058] Step S102 The controller automatically calculates the time T1 for the rolled piece from the first detector 1 to the second detector 2. In this step, when the head of the rolled piece reaches the first detector 1, the controller is triggered to start counting, and the head of the rolled piece reaches the second detector. The detector 2 triggers the controller to end timing, thereby automatically calculating the time T1=2.1 seconds required for the rolled piece to reach the second detector 2 from the first detector 1;

Embodiment 2

[0065] Step S101 sets the rolling parameters, and this step sets the length L=84 meters, the distance L1=31 meters between the first detector 1 and the second detector 2, the operating parameters of the steel loading device and the step-by-step cooling bed 7 operating parameters, wherein the distance L1 between the first detector 1 and the second detector 2 is set during debugging, and there is no need to set it again after the setting is completed;

[0066] Step S102 The controller automatically calculates the time T1 for the rolled piece from the first detector 1 to the second detector 2. In this step, when the head of the rolled piece reaches the first detector 1, the controller is triggered to start counting, and the head of the rolled piece reaches the second detector. The detector 2 triggers the controller to end timing, thereby automatically calculating the time T1=2.1 seconds required for the rolled piece to reach the second detector 2 from the first detector 1;

Abstract

The invention relates to a control method for automatic material distribution mode selection of a threaded bar stepping cooling bed. According to the control meth, rolling parameters are set; a controller automatically calculates the time of a rolled piece from a first detector to a second detector; the controller automatically calculates the speed of the rolled piece passing through a multiple-length flying shear; the controller automatically calculates the time of arriving at the stepping cooling bed in a multiple-length mode; the controller automatically calculates the time required by 360-degree operation of the stepping cooling bed; the controller automatically calculates the maximum number of rotatable turns of the stepping cooling bed; according to the actual length of each double-length, the most suitable material distribution mode of single-groove material distribution, partition-groove material distribution, ordered single-partition-groove material distribution and disordered single-partition-groove material distribution can be selected.

Description

technical field [0001] The invention relates to a production control method for threaded rods, in particular to a control method for automatically selecting the distribution mode of a step-by-step cooling bed for threaded rods. Background technique [0002] Cooling bed is one of the indispensable auxiliary equipment in small and medium-sized bar workshops. Its function is to cut the bar into multiple lengths by flying shear after rolling in the rolling mill, transport it through the steel loading device (roller into the roller table, brake skirt, straightening plate) and unload it to the cooling bed rack for cooling , so that the temperature is lowered from 900°C to 100-300°C, and then the cooling bed unloading device collects them into groups and sends them to the output roller table, and then the output roller table sends them to cold shears to cut into finished products. [0003] There are generally two types of common cooling bed distribution methods, that is, single-sl...
