Description

Automatic lifting mechanism for separating ring

Technical Field

The utility model relates to a strip production technical field specifically is automatic mechanism that lifts up of separating ring.

Background

The slitting machine is used for slitting coiled sheet materials such as silicon steel sheets, aluminum coils, galvanized coils, stainless steel, plain carbon steel and the like into a plurality of small strips along the length direction. The strip is cut through the circle shear, and after the separating ring rose, the strip got into the coiling machine rolling, and the reel rotated and coiled the strip after cutting, and the strip of coiling piles up on the reel and forms discoid, and at the rolling in-process, the separating ring is usually under hydraulic pump or motor drive, can produce certain vibration to destroy the disc side flatness, for preventing the separating ring vibration at the lift in-process, two kinds of modes have mainly been adopted among the prior art: 1. the pressure reducing valve and the reversing valve are arranged on the driving device to control the lifting of the separating ring, so that the vibration can be effectively prevented, but the device is not suitable for the thin strip, and the tension of the device is low, so that the separating ring is insensitive or stagnant when lifted, the separating work cannot be normally carried out, and the strip is even scratched when the separating work is serious; 2. the position of a strip is detected by installing a detection device such as a sensor, and the like, so that the lifting height of the separating ring is determined, on one hand, the strip on the winding drum is a curved surface, and the data detected by the detection device is inaccurate, and on the other hand, after the detection device sends signal commands such as lifting, descending, stopping and the like, the power hydraulic cylinder drives the separating ring to do corresponding actions according to the instructions, and when the signals are switched, the actions of the hydraulic cylinder can be interrupted, so that the actions of the separating ring are interrupted, the disc layer difference is caused, and the flatness is influenced.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: the utility model provides an automatic mechanism that lifts up of separating ring, its detect and be equipped with the encoder on the first swinging boom for gather the swinging boom and change along with the coil stock diameter and pivoted angle value, servo motor on the separating ring is rotatory according to encoder signal drive separating ring for the separating ring reaction is accurate sensitive, rotary inertia is little and steady, avoids ordinary motor to overshoot or lose the step phenomenon, thereby guarantees coil stock disc side roughness.

The utility model adopts the technical proposal that: it includes reel, support, separating ring, first swinging boom, detects head, second swinging boom, the reel is rotatably installed on the support, the separating ring is fixed in on the support through first swinging boom and is located the reel top, it is fixed in on the support and is located the reel top through the second swinging boom to detect the head, it is rotatory to be equipped with servo motor on the first swinging boom and through servo motor control, be equipped with the encoder on the second swinging boom for detect second swinging boom corner angle, through encoder and servo motor cooperation operation, make the separating ring can be steady accurate cut the strip.

Preferably, the second rotating arm is driven to rotate by a motor, and the encoder is positioned between the second rotating arm and a rotating shaft of the motor, so as to detect the rotating angle of the detection head in real time.

Preferably, the first rotating arm and the second rotating arm are the same in length, and the rotating change angles of the two rotating arms are kept constant and consistent with the increase of the diameter of the coiled material.

Preferably, the detection head and the separation ring are both tangent to the outer diameter of the web.

The utility model discloses automatic mechanism that lifts up of separating ring, its advantage is as follows: the encoder is arranged on the rotary arm of the detection head and used for collecting the angle value of the rotary arm rotating along with the change of the diameter of the coil stock, the servo motor on the separation ring drives the separation ring to rotate according to the encoder signal, so that the separation ring is correspondingly cut by the rotation angle, the angle value signal measured by the encoder is transmitted to the servo motor, the servo motor drives the rotary arm to rotate the separation ring, the servo motor has the advantages of accurate and sensitive reaction, small and stable rotation inertia, the phenomenon of overshoot or step loss of a common motor is avoided, and the flatness of the side face of the coil stock disc of a cut strip is guaranteed to be kept in the coil stock process.

Fig. 1 is a simplified view of the structure of the present invention.

The device comprises a winding drum 1, a winding drum 2, a support 3, a separating ring 4, a first rotating arm 5, a detection head 6, a second rotating arm 7 and a coil stock.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1, the utility model provides an automatic mechanism that lifts up of separating ring, it includes reel 1, support 2, separating ring 3, first swinging boom 4, detect head 5, second swinging boom 6, reel 1 rotatably installs on support 2, separating ring 3 is fixed in on support 2 and is located reel 1 top through first swinging boom 4, it is fixed in on support 2 and is located reel 1 top through second swinging boom 6 to detect head 5, it is rotatory to be equipped with servo motor on the first swinging boom 4 and through servo motor control, be equipped with the encoder on the second swinging boom 6, be used for detecting 6 corner angles of second swinging boom.

The second rotating arm 6 is driven to rotate by a motor, and the encoder is positioned between the second rotating arm 6 and the rotating shaft of the motor. In this embodiment, the lengths of the first rotating arm 4 and the second rotating arm 6 are the same, the distances between the rotating centers of the first rotating arm 4 and the second rotating arm 6 on the support 2 and the center of the reel 1 are the same, and the detecting head 5 and the separating ring 3 are both tangent to the outer diameter of the material 7 wound on the reel 1.

The principle is that, as shown in fig. 1, BC is the second rotating arm 6, and B is the rotating center; AE is the first rotating arm 4, a is the center of rotation; o is the coiling center of the reel 1; r is the initial radius of the coil stock 7, namely the radius of the winding drum 1; r is the radius of the coil stock 7 after being increased; BC, BD, AF, FE, and FE are constant values in the figure. Since OC is OE, OD is OF.

Initial state, for triangle BOC and triangle AOE, since BO ═ AO, CO ═ EO, BC ═ AE, triangle BOC and triangle AOE are congruent, so angle ∠ OBC ═ ∠ OAE ═ a;

the post-rotation state is that for triangle BOD and triangle AOF, because BO is AO, DO is FO, and BD is AF, triangle BOD and triangle AOF are congruent, so angle ∠ OBD is ∠ OAF is b;

therefore, the change angle of the second rotating arm 6 is ∠ CBD ∠ OBD- ∠ OBC b-a, the change angle of the first rotating arm 4 is ∠ EAF ∠ OAF- ∠ OAE b-a, so that the change angles of the second rotating arm 6 of the detection head 5 and the first rotating arm 4 of the separation ring 3 are always kept in a constant relation, through the calculation, the rotation angle of the detection head 5 on the second rotating arm 6 is collected through the encoder, the encoder transmits a signal to the servo motor, and the servo motor drives the separation ring 3 to correspondingly rotate, so that the purpose of controlling the position of the separation ring 3 in real time is achieved.
