Abstract
The utility model relates to equipment for cutting billets in the metallurgy industry, in particular to a device for cutting continuous casting billets of fixed weight, such as square billets, slab billets, rectangular billets, round billets and the like. The device for cutting continuous casting billets of fixed weight comprises a weighing mechanism, a computer processing system and a mechanism for cutting casting billets of fixed weight, wherein the computer processing system (B) is electronically connected with the weighing mechanism (A) and the mechanism (C) for cutting casting billets of fixed weight. The structure of the device realizes the purpose of cutting casting billets of fixed weight, and the process of cutting casting billets of fixed weight in a real-time online mode can be always realized without being affected by section change due to the abrasion of crystallizers, and other variable factors, such as pulling rate fluctuation, the thermal shrinkage rate of casting billets, and the like; the position can be correctly fixed during weighing; the control is realized by software so that errors caused by manual intervention can be avoided; peripheric electromechanical equipment can be conveniently maintained without being limited and affected by the production process or non-production process; the weight precision can be controlled within target weight plus or minus 1kg; the weight hit ratio can reach 91.63%; and the finished product rate is improved.
Description
(1) technical field
The utility model relates to the fixed cutting equipment of metallurgy industry base, specifically is that the fixed heavily cutting of strand such as square billet, slab, rectangular bloom and circle base etc. is provided with.
(2) background technology
The employed equipment of cutting control system of strand mainly contains at present: mechanical shutter control, three kinds of cutting control modes such as infrared ray control and shooting non-contact control.Its common characteristic is to belong to the sizing cutting, and difference is the control mode difference.Mechanical shutter control belongs to pure mechanical system, and its technology is coarse relatively, and it is big manually to adjust error, because the spacing movement response of mechanical shutter collision machine is slow, cutting error is also bigger.Infrared ray control is affected by the external environment easily, and it is loaded down with trivial details manually to adjust scale.The shooting non-contact control belongs to image information identification processing controls, aforementioned relatively two kinds of control modes, and it is more easy to operate, and cutting accuracy is with higher.But what adopt in follow-up rolling process is to decide regrate system, promptly requires in the cutting action process, and the strand that is cut will be stablized and is controlled in the constant weight scope, otherwise can cause the substandard products amount after rolling many, and lumber recovery is low etc., directly causes than large economy and loses.Thus the diced system of strand still be unrealized strand surely heavily the cutting.
(3) utility model technology contents
The purpose of the utility model is to overcome some defectives that prior art exists, and infrared scale cutting is combined with weighing technology, provides a kind of continuous casting billet heavy surely cutter sweep.
In order to realize above-mentioned purpose, the utility model is according to following technical scheme.The heavy surely cutter sweep of continuous casting billet comprises the heavy surely cutting mechanism of Weighing mechanism, computer processing system and strand, it is characterized in that: computer processing system weighs between the cutting mechanism surely with Weighing mechanism and strand and is electrically connected; Described Weighing mechanism comprises vertical overarm bracing frame, strand lifting device and weighing controller, is electrically connected on the vertical overarm bracing frame that the strand lifting device is fixed and with weighing controller.
The heavy surely cutting mechanism of described strand comprises fixed heavy PLC controller, image pick-up device, cutting medium controller, cutting and clamping device; Surely heavy PLC controller and image pick-up device all are electrically connected with computer processor; Be electrically connected between cutting and clamping device and the cutting medium controller, be electrically connected with heavy surely PLC controller again.
Superior part of the present utility model is:
Realized to strand heavily cutting surely that 1, be not subjected to the section variation that causes because of crystallizer wearing and tearing, the influence of variable factors such as pulling rate fluctuation, strand percent thermal shrinkage is always real-time online and heavily cuts surely.
2, weighing process accurate positioning, control procedure realize with software, have avoided the error of manual intervention, and peripheral electromechanical equipment maintenance and repair is convenient, are not produced or nonproductive process restriction and influencing.
3, the weight precision can be controlled in target weight ± 1kg scope, and weight is hit ratio can reach 91.63%.
4, lumber recovery improves 1.12%, and the scale cutting improves 0.2-0.5%, and negative difference rate improves 0.08-0.1%, and short chi is useless to be reduced more than 50%.
(4) description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model Weighing mechanism schematic diagram.
(5) specific embodiment
Concrete structure of the present utility model sees also accompanying drawing 1.Comprise the heavy surely cutting mechanism of Weighing mechanism, computer processing system and strand, concrete structure is that computer processing system weighs between the cutting mechanism surely with Weighing mechanism and strand and is electrically connected.This structure is the weighing of strand by Weighing mechanism, the computing of computer processing system self-regulated model, and the fixed PLC mechanism controls etc. of heavily cutting forms system's closed-loop control, reaches fixed heavily cutting control purpose.
Weighing mechanism described in the utility model comprises vertical overarm bracing frame 1, strand lifting device 2 and weighing controller 3, be electrically connected on the vertical overarm bracing frame 1 that strand lifting device 2 is fixed and with weighing controller 3, weighing controller (3) is electrically connected with computer (4).Referring to accompanying drawing 2.For making things convenient for the online or off-line maintenance and repair of equipment, strand lifting device 2 is fixed on the vertical overarm bracing frame 1, there be not any contact with the equipment such as roller-way, motor and reductor at scene, have a style of one's own.Therefore no matter fundamentally solved in process of production or in the nonproductive process, can both carry out maintenance and repair easily.For strand lifting control, be the logic of having utilized PLC, the function of arithmetic sum process control, the rising of control strand and decline also can stop rapidly accurately, make mechanism and electrical equipment avoid damaging.And weight information is the stable transmission to computer, be about to the weight parameter that obtains in the weighing controller 3,, reached stationary value when making the weighing of strand by the inside programming of PLC, hand over the mode of stable weight information again, transmit machine control system as calculated through serial communication.
Computer control system utilizes the noncontact image to handle and mode identification technology realizes the image recognition and the processing of online hot base, sets up the logical operation of fixed heavy and fixed length, and real-time online fine setting strand length, finally reaches fixed and heavily cuts.Concrete structure is to comprise heavy surely PLC controller 5, image pick-up device 6, cutting medium controller 7, cutting and clamping device 8 in the fixed heavy cutting mechanism of described strand; Fixed heavy PLC controller 5 and image pick-up device 6 all are electrically connected with computer processor 4; Be electrically connected between cutting and clamping device 8 and the cutting medium controller 7 again with heavy PLC controller 5 calmly and be electrically connected.
Concrete operations are to serve as demonstration and control platform with computer 4, gather pictorial information by high accuracy image pick-up device 6, be transferred to computer CPU, and with the weight information that receives by the relevant treatment computing between fixed heavy PLC controller 5 and the computer 4 after, finally send to cutting medium controller 7, finish the fixed heavily cutting of strand with pulse signal.
