Description

Coil distribution cooling apparatus

The present invention relates to a distributor (DISTRIBUTOR) of the reformed tube (REFORM TUB) in which the final rolled hot-rolled wire is wound directly after a heat treatment process in a spiral laminating coil formed by spiral coiling through a winding head. In particular, the present invention relates to a coil distribution winding device using a three-column rotary friction wheel that distributes windings uniformly without applying a defect to the coil surface in accordance with the falling direction of the falling coiling.

Usually, the coil falling into the reform tube is wound up after the various heat treatment process depending on the steel grade and size produced in the roll lacon bear transfer.

The heat treatment process is different from the direction and distance of the coiling and the total winding shape of the coiling to be integrated (falling) in the reforming tube after the completion of the transfer to the Rollaconbea, and due to the mass production of the defective winding product, the operation rate is lowered, thereby reducing the overall productivity. .

Conventionally, in order to solve the above problem, the motor and the reducer are mounted in the center of the reform tube (cone lower part), and a portion of the circular plate connected thereto drops the coil at the lower side of the reform tube cone. It is a device for distributing and winding the coiling integrated in the circumferential direction while being rotated regardless of the direction.

This inevitably causes severe friction on the surface when distributing the falling coiling, and the reducer bearing portion formed larger than the reforming tube diameter is easily burned down by the total self-weight and high thermal conduction, leading to rotational failure.

Not only the production of high-grade steel is difficult due to the above reason, especially low carbon steel with high surface elongation is impossible, and when the circular plate is not rotated, it has rather a winding obstacle.

Therefore, in view of the above, the present invention provides a circumferentially distributed circumference at the same time without any defect on the coil surface as the friction difference reciprocates and rotates according to the position when the direction and distance of integration are different according to the production steel grade and size change. It is characterized in that it is wound in close direction and smoothly rotated.

The following is described in detail with reference to the drawings.

In FIG. 1, a general final rolled hot-shaped ball-shaped material is formed by spiral coiling (1) through a winding head (2), and a heat treatment pattern (PATTERN) for each production size and steel type on a rollacon bea (2). ) And then wound directly in the reform tube (3).

The reforming tube structure consists of a tube (4) that serves as a coiling drop guide, a cone (5) therein, and a mandrel (10) supporting it. As a result, the coil collection plate 6 is wound (1-R) and the coil collection plate is gradually lowered (6-1) according to the height to be wound up to be finally wound up.

On the other hand, when the coil (1-R) on the coil collecting plate is transferred to the correction line, the continuous coil is rotated in conjunction with the pneumatic cylinder rod (7) by the four-way through hole (4H) of the tube (4). 8-1), it is wound onto the iris (IRIS) 8, which is inserted and supported by the cone.

The coil wound to the top of the iris while the coil collecting plate 6 and the mandrel descends simultaneously to transfer the coil to the correction line is the four-way iris (8) when the mandrel rises to the bottom of the cone 5 to support the cone. ) Is reversely rotated (8-1) in accordance with the pneumatic cylinder rod (7) coiling wound in the cone is repeatedly wound by falling to the collecting plate (6).

The coils 1-12 wound by the reforming tube operation have different shapes of integration with the drop direction toward the center of the cone depending on the production size and steel type. Transfer and delivery are impossible or left out.

According to a conventional Japanese patent (distributor) to solve the above problems, the circular plate 9P of the distributor 9 installed in a predetermined space at the center of the reform tube and the lower side of the cone is installed with the motor 9M. The coil ring (1-R ') which is connected to the gear reducer (9G) and rotates while rotating (9T) is distributed around the mandrel (10) in the circumferential direction to induce winding evenly and to form a low coil winding height. do.

However, this is achieved by the frictional force between the falling coil ring (1-R ') and the circular plate (9P) rotated in the circumferential direction, so that a defect (9) occurs on the coil surface and the reducer (9G) is formed larger than the diameter of the tube (4). ) The bearing (9B) is easily broken by the weight and the high temperature coil heat conduction, making the circular plate (9P) difficult to rotate.

As described above, when the circular plate is not rotated, winding failure occurs, and in the case of low carbon steel production, the occurrence of friction defect grooves is more severely generated. And the distributor structure and the role of a conventional coil distribution winding device will be described in detail with reference to FIG.

Fig. 2A is a perspective view and Fig. 2B is a cutaway view.

Rotor circular plate 9P embedded in distributor 9BA mounted on reform tube center base 2F (FIG. 1) is supported by bearing to rotate with gear reducer 9G and motor 9M and rotated. It consists of a guide tube (9TH) that is connected to the bottom of the tube (4) to the top.

Therefore, the present invention was devised to solve the above-mentioned problems, and the coiling shape is evenly distributed in the circumferential direction according to the integration state in the state that the coiling surface defect does not occur, so that the winding shape is horizontal and at the same time Its purpose is to make the coil winding quality improved and easy to deliver by making the height low and to distribute it smoothly even in high heat conditions.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention for achieving the above object is made of three rows of 120 ° angle in accordance with the direction of integration (falling) when the coiling heat-treated on the rollacon beacon integrated winding in the reform tube according to the production size and steel grade It provides a coil distribution winding device that rotates to induce the coiling to be distributed in the circumferential direction and simultaneously integrated in the center.

An embodiment of the coil distribution winding device according to the present invention,

In the wire coil integrated winding reforming tube (3),

Three rows of entry holes 11-H1, H2, H3 are formed through the lower center portion 2F at 120 °.

A fixed base 11-B1, B2 having a friction difference 11-1, 2, 3 having an inclination in a straight line with the hole incorporating a bearing ring and engaging into the motor 11-M1, M2, M3. B3) is coupled to the end, and the upper end of each shaft is connected to the rear end of the fixed base (11-B1, B2, B3) in the state of power connection with reducers (11G1, 11G2, 11G3) by the pneumatic cylinder (11-O1, O2) , O3 is connected to the lower end of the moving roller (11-R1), the fixed base moving roller integrally according to the pneumatic cylinder (11-O1, O2, O3) is constantly along the moving hole (RH) Repeated back and forth;

When the friction difference is in the reverse standby state, circular doors 11-D1, D2, and D3 which flow along the rail Ra mounted in the circumferential direction of the tube 4 to open and close the entrance holes 11-H1, H2, and H3. ) Is formed;

It is preferable to distribute the coiling in the circumferential direction as much as the inclination of the frictional difference as the three-row friction difference is interlocked and acted independently by the coiling drop direction and distance, and moves forward and backward to the entrance hole.

It will be described in detail with reference to the drawings.

FIG. 3 is an overall perspective view of the present invention, FIG. 4 is a 120 ° cutaway view of FIG. 3, and FIG. 5 is a planar cutaway view.

3, 4, and 5, the friction difference 11-1, 2, 3 is formed on the basis of the entry holes 11-H1, H2, H3 at the lower end of the reform tube 2F (center) at a circumferential 120 ° angle. Its lower surface is penetrated to coincide with the tip 11-T1, T2, T3 of the friction difference fixing base 11-B1, B2, B3 when entering, and the hole 11-H1, H2 when the friction difference does not proceed. Circular doors (DOOR) 11-D1, D2, and D3, which can open and close the H3, are formed in the circumferential direction on the upper and lower rails Ra to form the entire reform tube lower end 2F.

The friction difference forms an effective gap with the tube 4 in a state in which the friction difference coincides with each entry hole, and the friction difference is the motor 11- to the end of the fixed base 11-B1, B2, B3 in a state in which the bearing is embedded. In the state where M1, M2, M3 is built-in, the reduction gears 11G1, 11G2, 11G3 of each axis are coupled in a 1: 1 ratio to the upper side thereof, and a protective cover 11-C1, C2, C3 is formed at the upper end thereof. It is configured to transmit motor power.

On the other hand, by connecting the pneumatic cylinder (11-O1, O2, O3) to the rear of the fixed base to configure the friction difference rotates to the entrance holes (11-H1, H2, H3) according to the rod to be a reciprocating motion (DR) and the rear end of the base As an example, a roll (11-R) was mounted to facilitate base reciprocation. And a bidirectional guide hole (RH) was formed on the tube fixing base (2F) surface to maintain the reciprocating direction in a constant direction.

In addition, each motor (11-M1, M2, M3) operation is configured to rotate only the motor selected (used) according to the coil drop direction (production size, steel grade) or the entire rotation when the entire selection.

Hereinafter, the working state of the present invention will be described with reference to FIGS.

The coiling (1) heat-treated by the production size and steel type is transferred to the rollacon bea (2) to fall (integrated) to the collecting plate (6) at the bottom of the center of the reform tube (3) cone (5) and the collecting plate is hydraulic cylinder The winding (HY) cylinder gradually lowers to the end of winding (1-R), and winding (1-R) ends.

The coiling falling to the collecting plate is the cone (5) centered by the production size and steel type drop distance (roller cone beacon speed is high speed inertia effect after a long distance drop to the cone (5) and short speed progress if low speed Fall after) and the angle is changed.

In general, in the case of a rapid cooling steel grade, the conveying speed is accelerated and then integrated winding.

And because the fall angle distance proceeds uniformly according to the same steel grade and production size, the winding state does not change, and the winding degree changes closely when the steel grade and production size change.

In addition, in the case of the production of large diameter size, the fall angle is severe due to the above-mentioned cause and the winding load, which causes the wound state to be worse.

When the winding state is poor due to the difference in the travel distance and the falling angle due to the cone center as described above, as shown in FIG. 5, the friction wheels 11-1, 2, 3 formed in three rows of 120 circumferences at the lower part of the cone are the motors Pneumatic cylinder (11-O1, O2, O3) to the tube entry hole (11-H1, H2, H3) simultaneously and independently while rotating with the power of M3) and the reduction gears (11-G1, G2, G3) The coiling 1 falling along the guide hole RH of the fixed base rollers 11-R1, R2, and R3 is integrated with the rotation distribution A-A 'on both sides by the friction difference taper.

In addition, depending on the coil falling direction and winding shape (incline winding), it can be individually selected according to its use among three rows of friction cars (3 rows simultaneous entry, 2 rows entry, single entry, before each friction differential, reverse repetition entry). Distribute rotation.

When the friction wheel is not required or stops, rewind at each point and open the entrance holes 11-H1, H2, and H3 through the circular doors 11-D1, D2 and D3. Prevents conduction of jams and friction wheels.

As the three-row friction car rotates on the lower side of the cone as described above, the winding distribution is integrated in the circumferential direction of the coil ring (1-R) falling on the collecting plate 6 by the amount of taper, thereby winding uniformly regardless of production size and steel type. Wind the degree between the ring and the ring closely so that its height is low.

In addition, the fixed circular plate 9P of the conventional coil distributor has a holding frictional rotation in a circumferential, up and down circumferential direction at the bottom of the cone, and thus the surface defect occurs (a) and the efficiency decreases due to the coil distribution winding. .

In addition, the weight of the reducer and the rotational state of the high heat conduction furnace frequently occurred, but the present invention distributes the three-column friction difference by each part and simultaneously distributes the winding efficiency in the circumferential direction by the taper angle, thereby increasing the coil surface friction. No defects will occur.

As described above, according to the present invention, the coil winding state becomes poor when the roll conveyor conveying and heat treatment process is changed according to the hot wire production size and steel grade, and the coil surface defect grooves caused by the distributor and the winding efficiency decrease and It solves the defect of equipment and improves winding, coil transfer and transportation handling, and it has more stable production and prevented mass production of defective products.
