Abstract
The utility model provides a structural system of a finishing mill group structure system capable of meeting final requirements through eight finishing mills, a speed increasing box and two DC machines which are connected in series. The finishing mill group is characterized in that during the working process, the two DC machines are connected in series and output rotational speed, and power is transmitted to the eight finishing mills through the speed increasing box. The whole transmission structure is mounted conveniently on the spot and has simple debugging, long service life, low equipment failure rate, and convenient application and maintenance of the equipment and electrical control, and the service performance completely fits the application standard of high speed metallurgy wire rod. The utility model has the advantages of simple structure, smooth transmission, compact transmission structure, small occupied area, adoption of DC machines and sinicization of electric control systems; and the whole transmission structure has the advantages of low noise, small vibration value and large transmitting torque when put into practice and can effectively reduce the electrical control cost of high speed metallurgy wire rod finish equipment when used on the spot.
Description
Technical field
The utility model relates to a kind of equipment of metallurgical high speed wire rod finishing block group, is specifically related to the structural system of a kind of 8 finishing mills, gearbox and 2 direct current generator series connection.
Background technology
Along with high-speed rod project in recent years constantly increases in China, a lot of privately owned capitals change the high line of investment over to, and private firm's insufficient funds become the common fault of private firm, and this just requires us to reduce cost under the constant situation of existing equipment serviceability.Wherein finish rolling district master motor adopts direct current generator to replace alternating-current variable frequency motor, finishing mill to change 8, import finished product (bearing etc.) into by 10 to adopt production domesticization to become the emphasis that reduces whole line cost.
In former design, the power source of the high line mm finishing mill unit of whole piece is selected 5500 kilowatts of ac variable-frequency electric motors for use, control system adopts the ABB frequency-changing control system, but because of domestic technique falls behind, can't do the corresponding techniques support to equipment debugging and normal problems occured in operation, run into this type of situation and often will engage the foreign technology expert to solve, increased original cost virtually, also caused the increase in plant maintenance cycle simultaneously.After adopting 2 1500 kilowatts of direct current generators series connection, control system is simplified significantly, and the support of domestic technique can solve any problem of debugging and emerged in operation fully.The expenditure contrast of two aspects adopts direct current generator can save ten thousand yuans of 500-600.But because of the direct current generator maximum (top) speed does not reach application requirements, must make amendment to the existing structure of high-speed rod, this just requires us to adopt 2 finishing mills of minimizing to guarantee newly-designed requirement.
Summary of the invention
The purpose of this utility model is to provide 8 finishing mills of a kind of usefulness, gearbox and 2 1500 kilowatts of direct current generators to connect to reach the structural system of final requirement.For achieving the above object, the present invention adopts following technical scheme:
It mainly is by 8 finishing mills, 2 direct current generators and gearbox are formed, second finishing mill and the 4th finishing mill are connected in series, the 4th finishing mill and the 6th finishing mill are connected in series, the 6th finishing mill and the 8th finishing mill are connected in series, the 8th finishing mill and gearbox are connected in series, first finishing mill and the 3rd finishing mill are connected in series, the 3rd finishing mill and the 5th finishing mill are connected in series, the 5th finishing mill and the 7th finishing mill are connected in series, the 7th finishing mill and gearbox are connected in series, gearbox and direct current generator A are connected in series, and direct current generator A and direct current generator B are connected in series; Direct current generator A and direct current generator B are 1500 kilowatts of direct current generators; 8 finishing mills are installed in respectively on the frame, and wherein the frame of the 7th finishing mill, the installation of the 8th finishing mill is the ultrahigh speed frame, and 8 finishing stands adopt 45 ° of layouts of topcross, and adjacent frame is mutually 90 ° of layouts.
Mm finishing mill unit structurally mainly contains following characteristics:
-unit is by three
Milling train and five
Milling train is formed, and the intensity of unit has obtained tangible reinforcement;
-last two
Milling train is the ultrahigh speed frame, and unit speed is improved, and assurance speed can reach 80m/s;
-unit adopts 45 ° of layouts of topcross, has reduced the major axis height, has both increased the stability of unit, has reduced weight of equipment again, and Operation and Maintenance is also convenient;
-adjacent frame is mutually 90 ° of layouts, realizes no twist rolling;
Adopt after the technique scheme, this drive mechanism has following advantage:
1, simple, the stable drive of drive mechanism.
2, adopt direct current generator to replace alternating-current variable frequency motor, control system is significantly simplified, and has saved cost.
3, reduce by 2 finishing mill drive mechanism compactnesses, it is little to take up room.
4, whole drive mechanism is applied to that noise is low in the practice, the shake value is little, to transmit moment of torsion big.
Description of drawings
5, import finished product (bearing etc.) adopts production domesticization, and procurement price and spare part cost decline to a great extent.
Fig. 1 is a drive mechanism schematic diagram of the present invention; 1, first finishing mill wherein, 2, second finishing mill, the 3, the 3rd finishing mill, the 4, the 4th finishing mill, the 5, the 5th finishing mill, the 6, the 6th finishing mill, the 7, the 7th finishing mill, the 8, the 8th finishing mill, 9, gearbox, 10, direct current generator A, 11, direct current generator B.
Fig. 2 is 45 ° of structure charts of topcross;
Wherein: 1---3 are
Finishing mill,
4---8 are
Finishing mill,
The specific embodiment
9, gearbox, 10, direct current generator A, 11, direct current generator B.
