Description

The high speed tandem mill

Technical field the utility model relates to a kind of wire rolling mill, especially a kind of copper bar high speed tandem mill.

Background technology is present, and the domestic equipment that is used for processing metal line (mainly being copper cash) has wire rolling mill and wire drawing machine, adopts wire drawing machine and metal wire is worked into Φ 3 from Φ 8.Adopt the multistage transmission mechanism of high capacity motor and huge, heavy in the wire rolling mill, each frame all is to drive by transmission mechanism, and the transmission power consumption is big, and efficient is low.Although and the drawing process that wire drawing machine adopted is very ripe, because this technology is mainly dialled based on drawing, the resistance that produces in the production process is the combination of extruding and force of sliding friction, thereby it is very big to produce resistance.Simultaneously, because the technology that production equipment adopted still stays in mechanical stepless speed-regulating or electromagnetic speed-adjusting, and with regard to governing system, also is to reach synchronous by mechanical linkage, thereby exist a large amount of mechanical loss in the course of work, make the driving power of equipment must select very greatly.Metal wire is worked into the wire drawing machine of Φ 3 from Φ 8, and its main motor needs 75kw, and take-up and rolling motor are 18kw, and the power consumption of equipment itself is quite big, and especially under the situation that electric power is in short supply day by day at present, it is particularly outstanding that this problem just seems.

The summary of the invention technical problem to be solved in the utility model is to propose a kind ofly to adopt that rolling mill practice, equipment power dissipation are low, functional reliability and the high high speed tandem mill of production efficiency.

For solving the problems of the technologies described above, the utility model high speed tandem mill comprises support, raw material guiding device, processing unit (plant), wire drawing trimming device, wrap-up and electric control system, described processing unit (plant) is for rolling the wheel rolling device, it comprises continuously arranged multiple tracks rolling device, each road rolling device is respectively by a Motor Drive, whole machinery adopts electric control system to control its interlock, this electric control system comprises PLC, frequency converter, tension pick-up and operating desk, and described operating desk is the touch-screen operation bench.

Above-mentioned high speed tandem mill, described processing unit (plant) comprises by horizontal engine frame and vertical driving force frame space, eight roads that form of arranging continuously roll the wheel rolling device, described each power rack self has motor, and the motor of described each motor and described wire drawing trimming device is controlled its interlock by the inverter supply of described electric control system and by electric control system.

The utility model has adopted in the production process of metal wire (mainly being copper cash) and has rolled wheel rolling technology owing to adopted above-mentioned technical pattern, has replaced original drawing process.Owing to roll the resistance that exists in the wheel rolling for extruding with the combination of control power of rubbing of rolling, the extruding and the force of sliding friction resistance that exist in the drawing process have reduced the production resistance greatly.Simultaneously, the utility model than the former mechanical linkage mode that adopts, had both improved functional reliability owing to having adopted electric control system control appliance linkage manner to reach synchronously, had improved production efficiency again.Thereby the energy consumption of whole equipment of the utility model is quite low, has only 50kw, is 50% of same specification wire drawing machine.Production process adopts touch panel monitor system, and Various types of data shows clear, easy to operate, the automaticity height.The utility model is specially adapted to wire is worked into from Φ 8 processing of Φ 3.

Description of drawings is described in further detail the utility model below in conjunction with drawings and embodiments.

Fig. 1 is the structural representation of the utility model high speed tandem mill;

Fig. 2 is that the A of horizontal engine frame among Fig. 1 is to schematic diagram;

Fig. 3 is that the B of vertical power rack among Fig. 1 is to schematic diagram;

Fig. 4 is the electrical diagram of the utility model high speed tandem mill.

The specific embodiment such as Fig. 1, shown in Figure 4, the high speed tandem mill comprises support 1, raw material guiding device 2, processing unit (plant), wire drawing trimming device 3, wrap-up 4 and electric control system, raw material guiding device 2 comprises transmission frame 7 and transition apparatus 8, processing unit (plant) comprises that eight roads roll the wheel rolling device, and this eight road rolls the wheel rolling device by four horizontal engine framves 5 and four vertical driving force frame 6 spaces, arrange and form continuously.Each power rack 5,6 self respectively has a motor M (label is 11 among Fig. 2 and Fig. 3, down with) and reductor (being the double reduction case 12 shown in Fig. 2, Fig. 3) and by its driving.Whole machinery is controlled its interlock by electric control system, and this electric control system comprises PLC, frequency converter B, tension pick-up S and operating desk C, and operating desk C adopts 11.3 inches color touch screens, and by its monitoring whole process of production.The motor M (11) of each power rack 5,6 and the motor M of wire drawing trimming device 3 totally 9 motor control its interlock by the frequency converter B power supply of electric control system and by electric control system.As Fig. 2, shown in Figure 3, all comprise motor 11 (M), double reduction case 12, two roller frames 13, roll 14 and roll stand frame 15 in horizontal engine frame 5 and vertical driving force frame 6 its structures, the power shaft of reduction box 12 output shafts and two roller frames 13 is an axle, roll 14 by motor 11 (M) and reduction box 12 by power transmission shaft transmission (in the horizontal framework 6 by power transmission shaft and gear drive).These two kinds of power racks 5,6 have long service life, little, the efficient advantages of higher of transmission power consumption.The course of work of the utility model high speed tandem mill is as follows: 1, rolling Φ 8 bronze medal bars place and send on the frame 7; Open cooling fluid; Fine setting before the start to the independent adjustment before each motor M (11) work turns round on the per pass frame 5,6, is adjusted each frequency converter B to reach the inaccessiable gearratio of machine driving by touch-screen C.2, then working method is placed crawl; Under lower-speed state, connect Φ 8 bronze medal bar to the first frames, pass each road frame then successively, pass the wire drawing die finishing at last, then enter the winder rolling; The process that connects all adopts crawl to advance; After putting on the copper bar, working method places interlock, carries out synchronous acceleration and deceleration by the button on the touch-screen, to select suitable operating rate.Speed in the production process synchronously and balancing tension mainly rely on the vector of tension pick-up S and frequency converter B to feed back to reach.3, enter operate as normal then, can pass through data such as touch-screen standby current, frequency, fault this moment; After the one volume product process finishing, the concurrent responding sibilant rale of complete machine autostop notifying operation personnel; Cooling system quits work automatically.In the whole process, from raw copper to finished product copper wire output altogether through 9 procedures, rotating speed and the moment of motor M (11) have nothing in common with each other, it is adjusted control and is finished by the frequency converter B and the tension pick-up S of Speedless sensor vector controlled.
