Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, this system embodiment comprises workbench 1, baseline rod 2, operation bar 3, steel billet strip edge heater 4 and the not shown parts such as sensor, motor.Workbench 1 is positioned at a side of the conveyor roller 6 of the steel billets 5 such as transmission coil of strip, Strip, and baseline rod 2, operation bar 3 etc. is installed on workbench 1.When practical application, workbench 1 can be one or more, and multiple workbenches can be arranged at both sides or a side of conveyor roller 6.On each workbench 1, the baseline rod 2 that is offset for detection of steel billet 5, can arrange according to specific needs for the quantity of operation bar 3 of steel billet strip edge heater 4 that heating steel billet 5 limit portion regions are installed, be not limited to shown in Fig. 1.
More specifically, baseline rod 2 and a not shown position detecting device of the parts such as sensor, spring (torsion spring) composition.As shown in Figure 1, this position detecting device is positioned at a side of steel billet transportation roller-way 6, is installed on workbench 1, for detecting in real time the position of steel billet limit portion.Wherein, the limit portion of the first end of baseline rod 2 contact steel billet 5 is with the skew of sensing steel billet 5.Sensor is arranged in workbench 1 and is located at the second end 22 of baseline rod 2, and it is for gathering the steel billet limit portion shifted signal by baseline rod 2 first end sensings.This sensor can be displacement or the angular transducer such as mechanical type (such as rope sensor), electronic type (such as Hall element) of all kinds of end deflection for detection of baseline rod 2.In order to make baseline rod 2 have good stability, the second end 22 of baseline rod 2 is provided with a rotating shaft of stretching into workbench 2, and the second end 22 is rotatably located on workbench 2, weighs the side-play amount of steel billet with the anglec of rotation size of baseline rod 2.One torsion spring is set in rotating shaft, and being connected of the output shaft of this rotating shaft and a motor, this torsion spring can drive baseline rod 2 to rotate, reset to steel billet 5, and the limit portion of the first end that makes baseline rod 2 contact steel billet 5 tightly, to improve the degree of accuracy of detection.
In other embodiments, can also detect, follow the trail of the skew of steel billet 5 with the noncontacting proximity sensor such as infrared sensor that is arranged on roller-way 6 left sides, right side or upside, and export this shifted signal.
Steel billet strip edge heater 4 carries out local heat for the limit portion region to steel billet 5.It is installed on a heater supportive device.In the present embodiment, heater supportive device comprises operation bar 3 and not shown operation bar driving mechanism.The first end of operation bar 3 is installed steel billet strip edge heater 4, and the second end 32 is arranged on operation bar driving mechanism, and operation bar driving mechanism is arranged in a side of roller-way 6 and is positioned at workbench 1.The sensor of operation bar driving mechanism and position detecting device is connected, to move the limit portion region of steel billet strip edge heater 4 to steel billet 5 according to the position data of steel billet 5 limit portions.
Operation bar driving mechanism is a motor, this motor is arranged in workbench 1, the second end 32 of output shaft and operation bar 3 is connected, in the time that sensor detects that skew occurs steel billet 5, motor drives operation bar 3 to rotate different angles, thereby comply with the bias size of steel billet 5, in real time that steel billet strip edge heater 4 is corresponding with the limit portion of steel billet 5.If the oil cylinder that operation bar driving mechanism is output reciprocating motion, steel billet strip edge heater 4 is installed on the piston rod external part of oil cylinder, in the time there is skew in steel billet 5, the piston rod of this oil cylinder stretches out or bounces back, to comply with the skew of steel billet 5, in real time that steel billet strip edge heater 4 is corresponding with the limit portion of steel billet 5.
More preferably, as shown in Figure 1 and Figure 2, the first end of baseline rod 2 is provided with open frame 24, contact roller 21 for directly contacting steel billet 5 limit portions is installed in this open frame 24, install between the open frame 24 of contact roller 21 and the first end of baseline rod 2 and be provided with linking springs 23, the impact on baseline rod 2 while occurring to ignore displacement to filter the irregular or steel billet 5 of steel billet 5 limit portions.
Before application the present embodiment, baseline rod 2, operation bar 3 are all positioned on workbench 1, and the two moving direction along steel billet 5 extends, and also, the two is parallel with the direction of arrow in Fig. 1.
When application, first the present embodiment enters original state, and under original state, baseline rod 2 rotates to maximum deflection position, and this position is also with it the angle of 45 ° of angles or other proper angle along steel plate traffic direction.Contact roller 21 is positioned at roller-way 6 centerline, or the width that this contact roller 21 equals roller-way 6 apart from the vertical range of workbench 1 center line deducts needs the minimum steel billet plate of limit portion heating wide.The rotation of baseline rod 2 is driven by above-mentioned torsion spring, after end-of-job, when baseline rod is retracted to workbench 1, is driven by motor.
The operation bar driving mechanism start of operation bar 3, starts to receive the signal from sensor.
Roller-way 6 transports steel billet 5 through baseline rod 2, and baseline rod 2, under the drive of steel billet 5 limit portions, location deflection occurs.
When the contact roller 21 of baseline rod 2 first ends is subject to the promotion of transporting the steel billet 5 coming along roller-way 6, the sensor that is arranged at baseline rod 2 the second ends detects the limit portion position of steel billet 5 in real time, and this position data is delivered to the operation bar driving mechanism of operation bar 3, operation bar driving mechanism accurately moves to the steel billet strip edge heater 4 that is positioned at operation bar 3 first ends the limit portion region of steel billet 5 accordingly, thereby accurately controls heating region.Steel billet strip edge heater 4 provides to steel billet 5 heat up required electric power or the required gas that burns by job platform 1.As previously mentioned, according to on-the-spot needs, roller-way 6 both sides can be arranged symmetrically with a pair of job platform, and a baseline rod and at least one operation bar are set on each platform.If arrange under baseline rod 2 original states and become the angle of α ° with workbench 1 center line, under the drive of steel billet 5 limit portions, there is the deflection of β ° at initial position in baseline rod 2, inductor senses this deflection and transmits actuating signal to operation bar driving mechanism, when adopting motor, operation bar 3 drives while rotating into operating position operation bar 3 rotation alpha °-β °.In the time that operation bar 3 adopts hydraulic vertical to enter operating position, operation bar advances R*sin(alpha-beta), wherein, R is the radius of turn of baseline rod 2.
Finally, the region heating of steel billet 5 limit portions is complete, and in steel billet 5 is sent out by the operation of native system embodiment smoothly, baseline rod 2 and operation bar 3 return to original state.
To sum up, the utility model is by detecting the shift state of steel billet on conveyor roller, and according to steel billet the shift state on conveyor roller, adjust the position of steel billet strip edge heater, make the in real time corresponding and limit portion of heating steel billet of steel billet strip edge heater, can avoid steel billet to be offset the defects such as the steel billet limit portion heating region causing is unstable.Overview, the utlity model has following advantage:
