Abstract
A finishing mill group for rolling fine wires with 5.5-8 mm in diameter is the one driven by low-voltage middle-size or small-size AC asynchronous motor (without any speed variation). The single rolling mill is composed of electric motor, shaft coupling, gear distribution box, universal joint and frame. Said finishing mill group features that each single rolling mill has separate drive motor that is 380-V middle-or small-size AC asynchronous motor whose power is lower than 110 kw. The tandem rolling requirements for rolling fine wire can be met just by calculating the load of each single set and dynamic speed decreasement value of motor, selecting proper speed ratio for each mill set.
Description
The present invention relates to rolling machinery, particularly with the small-sized rod rolling mill group of the middle-size and small-size AC asynchronous motor of low pressure (not speed governing) as driving force.Rolling mill is made up of motor, shaft coupling, gear-box, Hooks coupling universal coupling, frame.Rod-rolling mill is divided into the high-speed rod tandem mill that dc motor (adjustable speed) drives both at home and abroad at present; The double two type rod-rolling mill that AC asynchronous motor drives; And the wire tandem rolling machine formed of many milling trains that pass through the transmission of gear distribution box collective that drive of separate unit AC asynchronous motor, above-mentioned two kinds not the common feature of adjustable speed-adjustable asynchronous electric motor driven wire finishing mill be to pass through a gear distribution box collective transmission number milling train with a high-power asynchronous ac motor.Double two type is to enter two rolling mills in addition again by 180 degree repeaters behind the two rolling mill tandem rollings.And their used asynchronous ac motors will use high-power, and voltage is generally six kilovolts, and power is generally more than 800 kilowatts.Be not suitable for the rolling diameter of bar mill and be 5.5 to 8 millimeters wire rod.
The objective of the invention is to utilize the unit driving force of the middle-size and small-size AC asynchronous motor of low pressure (not speed governing) as 5.5 to 8 millimeters rod-rolling mills of rolling diameter, the tandem mill of many unit compositions can satisfy the continuous rolling process requirement again.
The solution of the present invention is: the separate unit milling train has independently drive motor, the shaft coupling other end that is connected with separate unit milling train gear-box is to be that 380 volts of power are that middle-size and small-size asynchronous (not speed governing) motor below 110 kilowatts connects with voltage, each separate unit milling train has different motors and roll rotational speed, and the milling train of many different rotating speeds and pass is pressed continuous rolling relationship and formed the tandem rolling unit.
The key issue of continuous rolling process is that the metal mass flow of every unit keep to equate or just may set up stable continuous rolling relationship when equating, the characteristic curve of AC asynchronous motor shows, as long as the decline rotating speed Δ n (dynamic velocity drop) along with rolling load is the payload of every unit of accurate Calculation and suitable every motor power (output) size and its coupling selected, just can be than the dynamic velocity drop Δ n of every motor of accurate Calculation when rolling, according to the accurate speed ratio of the dynamic velocity drop difference design gear case of each motor, just can satisfy the continuous rolling process requirement again.
The invention has the advantages that and adopt the middle-size and small-size asynchronous AC motor of low pressure as the milling train driving force, its expense is cheap, and control is simple; Because motor is little and unit uni-drive gear box and the also light and handy miniaturization of transmission system, every milling train (containing about 3 tons altogether of motor shaft coupling gear-box, frames) is reduced investment outlay simultaneously.
Accompanying drawing one is a milling train unit structure connection layout.Accompanying drawing two is a finishing wire unit layout drawing.
1 is motor among the figure, and 2 is shaft coupling, and 3 is gear-box, and 4 is Hooks coupling universal coupling, and 5 is frame.
The present invention implements like this:
The separate unit milling train is made up of motor, shaft coupling, gear-box, Hooks coupling universal coupling and frame, and its motor is 380 volts of voltages, the AC asynchronous motor of power below 110 kilowatts, does not adopt any speed governing measure, and forms unit by some units.
According to principle of the present invention, designing program of designer is the roll pass that accurately designs and calculate each frame of tandem rolling, the metal full level, roll diameter of roller, roll rotational speed, mill speed, the Calculating Rolling Force Energy Parameters computing formula (Ai Ke Longde formula) that selection gears to actual circumstances is calculated the roll-force of each frame respectively, moment, power such as power energy parameter, according to a large amount of both at home and abroad statistics (designer collects) of putting into practice the power of calculating can parameter be revised again, obtain under various rolling temperatures, each frame is roll torque and magnitude of power more accurately, select each frame power and the synchronous rotational speed of the AC asynchronous motor of driving separately according to these parameters again, again according to the dynamic characteristic of AC asynchronous motor, calculate every asynchronous motor under the various loads dynamic velocity drop Δ n than exact value, again according to the dynamic state speed reducing value Δ n of each AC asynchronous motor in the operation of rolling that drives each frame

3Revise the adjacent two rolling mills speed ratio of gear-box separately.Can obtain very satisfactory achievement and invest extremely cheap with the wire tandem rolling unit that mentioned above principle is designed.
Above-mentioned designing and calculating will be wanted difficulty and complicated many compared with the rod-rolling mill of double two type rod-rolling mill and single motor collective transmission multimachine frame.But a GPRS correct method is listed the various formula that gear to actual circumstances, and all difficulties can be readily solved.
Following tabulating, taking out in the tandem mill 10 millimeters rolled pieces of diameter, to become diameter through four frame tandem rollings be instance data and each frame rolled piece cross dimensions Fig. 3 of 6 millimeters wire rods
