Strap tension control setup in the heat treatment furnace stove of the utility model, the technique effect that adopts technique scheme to obtain is:
Strap tension control setup in the heat treatment furnace stove; Comprise dance roller; Between dance roller and heat treatment furnace inlet hightension measuring roller measuring mechanism and small tension receiving coil dancer roll measuring mechanism are set, hightension measuring roller measuring mechanism is provided with hightension measuring roller base, hightension measuring roller support and hightension measuring roller, the axis of hightension measuring roller and the surperficial parallel of band and vertical with the working direction antarafacial of band; The hightension measuring roller is rotaryed connection with hightension measuring roller support; Hightension measuring roller support is hinged along an end and the hightension measuring roller base of the working direction of band, and the parallel axes of the axis of pivotally attached jointed shaft and hightension measuring roller is at the other end of hightension measuring roller support along the working direction of band; Between hightension measuring roller support and hightension measuring roller base, pressure sensor is set; The stressed back of hightension measuring roller hightension measuring roller support can make pressure sensor produce electric signal around the hinge-point swing offset, is used for the Tension Control of band.Band holds the part surface of hightension measuring roller, can make the tension force of band pass to the hightension measuring roller, and make pressure sensor produce corresponding electric signal, for the Tension Control of band provides control signal.Small tension receiving coil dancer roll measuring mechanism is provided with frame, 2 guiding rollers, wheel shaft, dancer roll, counter weight, frequency control motor and magnetic-powder clutchs; The axis of dancer roll and the surperficial parallel of band and vertical with the working direction antarafacial of band, wheel shaft is rotaryed connection with frame, wheel shaft setting beat running roller and drive wheel; The dancer roll setting roll shaft of beating; Dancer roll is rotaryed connection with the roll shaft of beating, and beats the suspension chain is set between roll shaft and the counter weight, captives joint with counter weight with the roll shaft of beating in the two ends of suspension chain; The middle part of suspension chain holds the running roller of beating; Dancer roll and counter weight are suspended on the down either side of the running roller of beating, and the weight of counter weight is identical with the weight of dancer roll, realize gravitational equilibrium in the time of can making the dancer roll that is suspended on the running roller of beating and counter weight not receive external force.The output shaft of frequency control motor and the input shaft of magnetic-powder clutch are in transmission connection; The output shaft of magnetic-powder clutch is connected with the drive wheel chain gear, and 2 guiding rollers are separately positioned on the down either side of dancer roll, the axis of 2 guiding rollers and the parallel axes of dancer roll along the working direction of band; Band holds the part surface of 2 guiding rollers; Around the part surface of dancer roll or do not hold the part surface of dancer roll, when the tension force of band was big, band did not hold the part surface of dancer roll to band through the tundish of 2 guiding rollers; Utilize hightension measuring roller measuring mechanism to measure the tension force of band, the tension force of band is regulated through dance roller.At the tension force of band hour; Because the sensitivity of hightension measuring roller measuring mechanism is not enough, can't accurately measure and control the tension force of band, change the part surface that band holds dancer roll into; The tension force of band acts on the dancer roll; Make dancer roll moved down by the tension force pulling of band, dancer roll drives the rotation of dancer roll wheel through connected suspended chain bar, and frequency control motor drives the drive wheel backward rotation through the magnetic-powder clutch chain drive-belt; Move up with the drive wheel siamesed moving dancer roll of running roller rotating band of beating, make band produce suitable tension force.The variation of strap tension is through the displacement of dancer roll and the transmission of suspension chain, chain, magnetic-powder clutch; The output torque of frequency control motor is changed; Utilize the torque control function of frequency control motor; Can converse the situation of change of strap tension according to this, as the control foundation of strap tension.Under the less situation of the tension force of band, change the upright position of dancer roll, can adjust the tension force of band.Because dancer roll is undertaken freely being suspended on the running roller of beating after the gravitational equilibrium by counter weight; The swivel bearing rigidity of hanger bearing ratio of rigidity hightension measuring roller support is much little; The variation of the strap tension that therefore obtains through frequency control motor is much sensitiveer than the variation of the strap tension that hightension measuring roller measuring mechanism obtains; During the tension variation of band; Tangible change can take place in the upright position of dancer roll, makes frequency control motor have the ability that very high detection strap tension changes, so small tension receiving coil dancer roll measuring mechanism can satisfy the needs of the strap tension control under the small tension receiving coil state.When band keeps suitable tension force and is in stabilized conditions; Transfer torque through the control magnetic-powder clutch; Produce skidding when can make magnetic-powder clutch transmit steady torque; When making frequency control motor pass through magnetic-powder clutch to transmit stable moment of torsion, the motion output that keeps zero rotating speed makes band keep stable, suitable tension force.
Strap tension control setup in the heat treatment furnace stove, the length of suspension chain adapts with the miles of relative movement of dancer roll, and the length that can avoid hanging chain limits the miles of relative movement of dancer roll inadequately, makes the miles of relative movement of dancer roll satisfy the needs that strap tension is controlled.
Strap tension control setup in the heat treatment furnace stove; Reductor is set; The input shaft of reductor and the output shaft of frequency control motor are in transmission connection, and the output shaft of reductor and the input shaft of magnetic-powder clutch are in transmission connection, and can improve the rotating speed of frequency control motor; Improve the efficient of frequency control motor, reduce the power of frequency control motor.
Strap tension control setup in the heat treatment furnace stove, dance roller is provided with the dance roller control mechanism, is convenient to adjust the tension force of dance roller with the control band.Control setup is set, and control setup is programming controller or Computer Control Unit, and control setup is electrically connected with pressure sensor, dance roller control mechanism, magnetic-powder clutch and frequency control motor, can realize the automatic guidance of strap tension.
Use the interior strap tension control setup of heat treatment furnace stove of the utility model, can accurate, the stable strap tension that vary in size be provided for the band of unlike material, thickness and width in the process of continuous heat, effect is remarkable.
