Description
Technical Field
The invention relates to the technical field of metal bar sampling, in particular to a bar cold bed hot card sampling automatic control method.
Background
In a bar production workshop of an iron and steel manufacturing enterprise, a bar is cut into multiple lengths of bars by flying shears controlled by a PLC, then the bars are conveyed to a cooling bed through a roller way controlled by the PLC, and are output after being cooled on the cooling bed, and the PLC is connected with an upper computer which inputs control instructions to the PLC. Generally, for guaranteeing production quality, this in-process will carry out the spot check to the multiple length rod, will take a sample to the testing sample of multiple length rod earlier during the spot check, the sample of current testing sample is usually the manual work and goes on, one of the random extraction multiple length rod takes a sample, because the rollgang is incessantly carried multiple length rod to the cold bed, and after these multiple length rods were thrown the cold bed, its afterbody is neat, and the sample point heat temperature is high, consequently, there is the unable clear differentiation which one is the multiple length rod after the sample, cause not only to influence product quality, and extravagant raw and other materials, increased manufacturing cost's problem.
Disclosure of Invention
The invention provides a method for automatically controlling the sampling of a hot card of a bar cooling bed, which can solve the problems that the quality of a product is influenced, raw materials are wasted and the production cost is increased because the section of a multi-length bar after sampling cannot be clearly distinguished in the conventional bar cooling bed hot card sampling.
In order to solve the problems, the technical scheme adopted by the invention is as follows: the automatic control method for the hot card sampling of the bar cold bed adopts a PLC for controlling the cutting action of a flying shear and the conveying speed of a roller way, and the PLC is connected with an upper computer;
the control method comprises the following steps: the method comprises the steps that firstly, an additional length value of a multi-length bar and a cutting numerical value of a flying shear during sampling are preset through an upper computer, when a PLC receives a sampling instruction, the cutting number of the flying shear is counted, when the preset cutting numerical value is reached, the PLC adds the preset additional length value of the multi-length bar to the length value of the multi-length bar cut at this time, and meanwhile, the conveying speed of a roller way is controlled to be slowed down until the multi-length bar sampled is finished steel throwing; to cycle through the next cycle.
In the above technical solution, a more specific technical solution may also be: and when the PLC adds the preset additional length value to the length value of the multi-length bar to be cut, controlling the length value of the multi-length bar to be cut to be the original length value plus the additional length value.
Further: when the preset cutting number is reached, firstly, the sampling enable is triggered, then the PLC adds the additional length value of the preset multiple length bar to the length value of the multiple length bar to be cut, and after the sampling is finished, the sampling enable is immediately cancelled.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
according to the method, the additional length value of the multi-length bar and the cutting number of the flying shears during sampling are preset through the upper computer, when the PLC receives a sampling instruction, the cutting number of the flying shears is counted, when the preset cutting number is reached, the PLC adds the additional length value of the preset multi-length bar into the length value of the multi-length bar cut at this time, meanwhile, the conveying speed of the roller way is controlled to be slowed down until the steel throwing of the sampled multi-length bar is finished, and the next period is circulated; can instruct the cold bed heat card to formulate sample plan and sample length, the length value that makes the multiple length rod of treating the sample is greater than the length value of ordinary multiple length rod, prevent that random sampling from causing multiple length not long enough to form non-chi, the sample steel stretches out and with ordinary multiple length rod interval certain distance, not only conveniently take and take a sample, multiple length rod after the sample is the same with the length dimension of ordinary multiple length rod, the lumber recovery is improved, the waste of raw and other materials has been avoided, the production cost is reduced, simultaneously, the work efficiency is also improved, and the labor intensity is reduced.

Fig. 2 is a control block diagram of the roller table and the cooling bed according to the embodiment of the present invention.
Detailed Description
The invention will be further described in detail with reference to the following examples:
the bar cooling bed hot card sampling shown in fig. 1 is performed in the process that a bar is cut into a multiple length bar 2 by a flying shear 1 and then is sent to a cooling bed 4 through a roller bed 3 to be cast on a steel upper cooling bed 4, wherein a mark 5 is a multiple length bar to be sampled, the length value of the multiple length bar 5 before sampling is larger than that of the common multiple length bar 2, and the length value of the multiple length bar 5 after sampling is equal to that of the common multiple length bar 2; as shown in fig. 2, the control ports of the PLC6 are respectively connected to the ports of the flying shear driving unit 7 and the transmission unit 8, the flying shear driving unit 7 drives the flying shear 1 to cut, and the transmission unit 8 controls the operation of the roller bed 3; the PLC6 is connected with the upper computer 9;
the method for automatically controlling the bar cold bed hot card sampling comprises the following steps: the method comprises the steps that firstly, an additional length value of a multi-length bar and a cutting number of a flying shear during sampling are preset through an upper computer, when a PLC receives a sampling instruction, the cutting number of the flying shear is counted, when the preset cutting number is reached, a sampling enabling function is triggered, then the PLC adds the preset additional length value of the multi-length bar to the length value of the multi-length bar to be cut, and the length value of the multi-length bar to be cut is controlled to be the original length value plus the additional length value; meanwhile, the conveying speed of the roller way is controlled to be slowed down, so that the position of the cut multi-length bar material on the cooling bed is separated from the common multi-length bar material by a certain distance, and the distance is controlled within the effective range of the sampling length; until the sampled multi-length bar is polished, the sampling enable is cancelled immediately, so that the influence on the normal polishing of the next multi-length bar is prevented; to cycle through the next cycle.
The invention can guide the hot card of the cooling bed to make a sampling plan and a sampling length, so that the length value of a multi-length bar to be sampled is larger than that of a common multi-length bar, the phenomenon that the multi-length bar is not long enough to form a non-length bar due to random sampling is prevented, the sampling steel extends out and is spaced from the common multi-length bar by a certain distance, the taking and the sampling are convenient, the length size of the sampled multi-length bar is the same as that of the common multi-length bar, the yield is improved, the waste of raw materials is avoided, the production cost is reduced, the working efficiency is improved, and the labor intensity is reduced.
