The guide track is sleeved and provided with a floating piece which can slide; the floating piece is fixed and provided with a fixed upper sensor rod and a lower sensor rod; the fixed rod is from top to bottom provided with an upper limitation sensor switch, the upper sensor rod, the lower sensor rod, and a low limitation sensor rod; the floating piece is provide with a clamping block; the clamping block is provided with a chamber which is for the steel bond going through; and the floating piece moves on the guide track according to the bending quantity of the steel bond between the front roller and the back roller, thereby driving the floating piece and the sensor rods to move, and then making the sensor switch send out a signal, followed by feeding back to the two pairs of rolling wheels; thus the speed of the two pairs of rolling wheels can be the best matching and the steel bonds processed are even with increased processing efficiency and quality.

Description

The speed testing agency of rolling mill

Technical field

The utility model relates to a kind of speed testing agency of rolling mill, is applicable to the detection and the feedback of steel band speed of rolling wheel in the operation of rolling.

Background technology

In the cold-rolled process of steel band, in order to make the steel band thin and thick after the processing even, steel band need pass through the roll extrusion of the two pairs of rolling wheels in front and back of rolling mill successively usually, and the speed of two pairs of rolling wheels must be mated and can be guaranteed that steel band is not broken and thin and thick is even simultaneously.In the prior art, often realize the constant airspeed of two pairs of rolling wheels, usually piled up, cause the steel band uneven distribution that processes and be physically located in two pairs of steel bands between the rolling wheel by setup parameter, even when output, broken, influenced the efficient and the quality of steel band processing.

Summary of the invention

The utility model purpose provides a kind of speed testing agency of rolling mill, it can be according to the condition signaling of steel band in the processed process of reality, feed back to two pairs of rolling wheels, make the speed of two pairs of rolling wheels be complementary, thus the output steel band that thin and thick is even, quality is higher.

The technical solution of the utility model is: a kind of speed testing agency of rolling mill, it comprises base, be fixedly connected on the guide rail that extend perpendicular to the horizontal plane direction on the edge on the base, the fixed bar that is provided with permanently with described base, be socketed with rocker piece on the described guide rail slidably, be set with induction rod and following induction rod on the described rocker piece, described fixed bar is provided with the limes superiors inductive switch, there is the last inductive switch that is arranged on the described fixed bar below of described limes superiors inductive switch, there is the following inductive switch that is arranged on the described fixed bar described below of going up inductive switch, there is the limit inferior inductive switch that is arranged on the described fixed bar the described below of inductive switch down, be fixedly connected with locating piece on the described rocker piece, be connected with at least one pair of clamp on the described locating piece, be provided with the cavity that passes through for steel band between the described clamp.

The upper end of described guide rail is provided with cross bar, an end of the extension spring that is permanently connected on the described cross bar, and the other end of described extension spring is connected on the described rocker piece.

The utility model compared with prior art has following advantage: described rocker piece can move on guide rail according to the case of bending of steel band between prime rolling wheel and back level rolling wheel, thereby driving induction rod moves, and then triggering inductive switch, the feedback signal of sending by inductive switch, finally feed back to two pairs of rolling wheels, make the speed of two pairs of rolling wheels be complementary, thereby the output steel band that thin and thick is even, quality is higher has improved the efficient and the quality of processing.

The specific embodiment

Referring to accompanying drawing 1 to accompanying drawing 2, a kind of speed testing agency of rolling mill, it comprises base 1, be fixedly connected on the guide rail 2 that extend perpendicular to the horizontal plane direction on the edge on the base 1, the fixed bar 3 that is provided with permanently with described base 1, be socketed with rocker piece 4 slidably on the described guide rail 2, be set with induction rod 5 and following induction rod 15 on the described rocker piece 4, described fixed bar 3 is provided with limes superiors inductive switch 7, there is the last inductive switch 6 that is arranged on the described fixed bar 3 below of described limes superiors inductive switch 7, there is the following inductive switch 16 that is arranged on the described fixed bar 3 described below of going up inductive switch 6, there is the limit inferior inductive switch 17 that is arranged on the described fixed bar 3 the described below of inductive switch 16 down, be fixedly connected with locating piece 11 on the described rocker piece 4, be connected with at least one pair of clamp 12 on the described locating piece 11, be provided with the cavity that passes through for steel band 10 between the described clamp 12.

The speed testing agency of described rolling mill is arranged between the prime rolling wheel 8 and back level rolling wheel 9 of rolling mill, and processed steel band 10 passes the described cavity that is arranged between the described clamp 12.When steel band 10 is piled up between prime rolling wheel 8 and back level rolling wheel 9, steel band 10 meetings are crooked and drive the slip up or down on guide rail 2 of described rocker piece 4, and the last induction rod 5 and the following induction rod 15 that are fixed on the described rocker piece 4 move up and down with rocker piece 4; When being in the optimum range as the amount of bow of steel band 10, be arranged at last inductive switch 6 on the described fixed bar 3, limes superiors inductive switch 7, inductive switch 16, limit inferior inductive switch 17 all are not triggered down, the speed that shows two pairs of rolling wheels is in optimum range and be complementary; When if steel band 10 amount of bow up or down is excessive, the displacement of last induction rod 5 or following induction rod 15 is bigger, thereby make the limes superiors inductive switch 7 or the limit inferior inductive switch 17 that are arranged on the described fixed bar 3 be triggered, the discharging speed that shows the too fast level then of the feeding speed of prime rolling wheel 8 rolling wheel 9 is slow excessively, limes superiors inductive switch 7 or limit inferior inductive switch 17 send signal, and finally feed back to prime rolling wheel 8 and a back level rolling wheel 9 makes the speed of two pairs of rolling wheels be complementary; When steel band 10 is tightened up between prime rolling wheel 8 and back level rolling wheel 9, steel band 10 drives described rocker piece 4 and slides up or down on guide rail 2, the last induction rod 5 and the following induction rod 15 that are fixed on the described rocker piece 4 move with rocker piece 4, at this moment be fixed on the last induction rod 5 on the described rocker piece 4 or descend the displacement of induction rod 15 less, thereby make described upward inductive switch 6 or following inductive switch 16 be triggered, it is too fast that the feeding speed that then shows prime rolling wheel 8 is crossed the discharging speed of the slow rolling wheel 9 of level then, described go up inductive switch 6 or down inductive switch 16 send signal, and finally feed back to prime rolling wheel 8 and a back level rolling wheel 9 makes the speed of two pairs of rolling wheels be complementary.

The upper end of described guide rail 2 is provided with cross bar 14, an end of the extension spring 13 that is permanently connected on the described cross bar 14, and the other end of described extension spring 13 is connected on the described rocker piece 4.
