Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical rolling, and specifically to a bar water cooling control method. Background Art

[0002] As one of the important products in the steel industry, bars are widely used in the construction, machinery and metal products industries. The controlled cooling technology, as an effective method to improve the mechanical properties of bars, has developed rapidly. The controlled cooling technology of the bar production line is realized by arranging water cooling devices before and after the finishing mill group and the roller table in the recovery section.

[0003] The product size range of the medium and small bar production line is from 10mm to 90mm in diameter, and the product size span is large. During the production process, due to the frequent replacement of product specifications, if the center line of the bar is not aligned with the center line of the water tank water cooling unit, the upper and lower surfaces of the rolled piece are unevenly cooled, which will cause "yin-yang surfaces" on the rolled piece and affect the mechanical properties of the product.

[0004] In order to solve the problem of "yin-yang surfaces", the current controlled cooling technology adopts the method of adjusting the height of the front and rear conveying roller tables of the water tank. The first method is to adjust the height of the roller surface by adding gaskets with different thicknesses to the roller table frame. In this way, the conveying roller table and the base must be lifted as a whole, and then gaskets are added under the roller table frame. The adjustment process is complex, the labor intensity of workers is large, and the production efficiency is low. The second is to set a lifting mechanism driven by a screw jack under the roller table frame to achieve the adjustment of the roller table height. This method requires a set of lifting mechanisms to be set under each group of rollers of the front and rear roller tables of the water tank and the roller tables inside the water tank. The equipment cost is high, there are many devices to be adjusted, and the operation takes a long time. Summary of the Invention

[0005] In order to solve the problem of difficult adjustment of the height of the front and rear conveying roller tables of the water tank in the above-mentioned prior art, the present invention provides a bar water cooling control method, which adopts a lifting mechanism and a transverse moving trolley, and can conveniently adjust the position of the water tank in the up and down direction and also conveniently adjust the position of the water tank in the left and right direction.

[0006] The technical solution adopted by the embodiments of the present invention to solve its technical problems is:

[0007] A bar water cooling control method, which adopts a bar water cooling device. The bar water cooling device includes a water tank, a lifting mechanism and a transverse moving trolley connected in sequence from top to bottom. A water cooling unit is arranged on the water tank. The lifting mechanism can move the water tank in the up and down direction, and the transverse moving trolley can move the water tank and the lifting mechanism in the left and right direction. The rolled piece can pass through the water tank in the front and rear direction;

[0008] The bar water cooling control method includes the following steps:

[0009] The transverse trolley moves the water tank and the lifting mechanism in the left - right direction until the center line of the water - cooling unit is directly opposite to the center line of the rolled piece in the up - down direction, and the lifting mechanism moves the water tank in the up - down direction until the center line of the water - cooling unit coincides with the center line of the rolled piece; or, the lifting mechanism moves the water tank in the up - down direction until the center line of the water - cooling unit is directly opposite to the center line of the rolled piece in the left - right direction, and the transverse trolley moves the water tank and the lifting mechanism in the left - right direction until the center line of the water - cooling unit coincides with the center line of the rolled piece.

[0010] The beneficial effects of the embodiments of the present invention are as follows:

[0011] 1. The water - cooling device can be lifted, ensuring that the center line of the water - cooling unit is directly opposite (coincides) with the center line of the rolled piece, and the upper and lower surfaces of the rolled piece are evenly cooled, improving the mechanical properties of the product.

[0012] 2. The method is convenient to operate and has high production efficiency. Only the height of each water tank needs to be adjusted, without the need to separately adjust the heights of the front and rear roller tables and the inner roller table of the water tank, reducing the operation procedures.

[0013] 3. The equipment structure is simple and reliable. The lifting mechanism adopts a worm - gear reducer with self - locking and a motor with an internal brake, and the motor and the reducer are far away from the water - gas area through a long coupling, ensuring the reliable and stable operation of the equipment.

[0035] As Figures 1 to 2 shown, a bar water cooling device according to an embodiment of the present invention includes a water tank 1, a lifting mechanism 3, and a traversing trolley 4 that are connected in sequence from top to bottom. The lifting mechanism 3 can move the water tank 1 in the vertical direction, and the traversing trolley 4 can move both the water tank 1 and the lifting mechanism 3 in the horizontal direction. The rolled piece can pass through the water tank 1 in the front-rear direction.

[0036] The bar water cooling device of the present invention includes a lifting mechanism 3 and a traversing trolley 4. The water tank 1 is located on the lifting mechanism 3, and the lifting mechanism 3 is fixed on the traversing trolley 4. It can conveniently adjust the position of the water tank 1 in the vertical direction and also conveniently adjust the position of the water tank 1 in the horizontal direction. It is not necessary to separately adjust the heights of the front and rear roller tables of the water tank and the inner roller table of the water tank, reducing the operation process, with the advantages of convenient specific operation and high production efficiency.

[0037] As Figures 3 to 6 shown, the lifting mechanism 3 includes a lifting shaft 32, a transmission mechanism, and a driving device that are connected in sequence. The lifting shaft 32 extends in the horizontal direction. An eccentric wheel 35 is sleeved outside the lifting shaft 32. The eccentric wheel 35 is fixedly connected to the lifting shaft 32 (such as a key connection). The eccentric wheel 35 cannot rotate relative to the lifting shaft 32. The water tank 1 is in vertical contact with the eccentric wheel 35. The driving device can drive the eccentric wheel 35 to rotate around the lifting shaft 32 and move the water tank 1 in the vertical direction.

[0038] Two eccentric wheels 35 can be fixedly sleeved outside each lifting shaft 32. The eccentric wheel 35 can rotate around the axis of the lifting shaft 32. The two eccentric wheels 35 are arranged at intervals in the horizontal direction. The lifting mechanism 3 can include three lifting shafts 32. The three lifting shafts 32 are arranged at intervals in the front-rear direction. Along the direction from front to back, the three lifting shafts 32 are respectively the first lifting shaft 321, the second lifting shaft 322, and the third lifting shaft 323 in sequence. Each eccentric wheel 35 is the same, and each lifting shaft 32 is also the same.

[0039] As Figure 7 shown, a slide plate 33 is fixedly connected to the lower part of the front of the water tank 1. A card slot 331 is provided on the lower surface of the slide plate 33. The card slot 331 extends in the front-rear direction, that is, the card slot 331 is opened in the front-rear direction. The upper end of the eccentric wheel 35 outside the first lifting shaft 321 is inserted into the card slot 331 in a matching manner. The function of the card slot 331 of the slide plate 33 at the front of the water tank 1 is to prevent the water tank 1 from moving in the horizontal direction relative to the eccentric wheel 35 outside the first lifting shaft 321.

[0040] As Figure 4As shown in the figure, a reversed U-shaped frame 31 is fixedly connected to the lower part of the middle of the water tank 1. The reversed U-shaped frame 31 includes a front vertical plate 311, an upper horizontal plate 312, and a rear vertical plate 313 that are connected in sequence from front to back. The front vertical plate 311, the upper horizontal plate 312, and the rear vertical plate 313 enclose an accommodation space. The eccentric wheel 35 outside the second lifting shaft 322 is located in the accommodation space. The opening of the accommodation space faces downward. The eccentric wheel 35 outside the second lifting shaft 322 is in contact with the front vertical plate 311, the upper horizontal plate 312, and the rear vertical plate 313. The eccentric wheel 35 outside the second lifting shaft 322 can rotate relative to the reversed U-shaped frame 31. The function of the reversed U-shaped frame 31 is to prevent the water tank 1 from moving in the front-rear direction relative to the eccentric wheel 35 outside the second lifting shaft 322.

[0041] A sliding plate 33 is fixedly connected to the lower part of the rear of the water tank 1. A card slot 331 is provided on the lower surface of the sliding plate 33. The card slot 331 extends in the front-rear direction, that is, the card slot 331 is opened in the front-rear direction. The upper end of the eccentric wheel 35 outside the third lifting shaft 323 is inserted into the card slot 331 in a matching manner. The function of the card slot 331 of the sliding plate 33 at the rear of the water tank 1 is to prevent the water tank 1 from moving in the left-right direction relative to the eccentric wheel 35 outside the third lifting shaft 323.

[0042] Both ends of the left end of the lifting shaft 32 are provided with first bearing seats 34. The lifting shaft 32 is connected to the first bearing seats 34 through bearings. Both first bearing seats 34 are fixed on the transverse moving trolley 4. The left first bearing seat 34 is located outside the left side of the water tank 1, and the right first bearing seat 34 is located outside the right side of the water tank 1. Along the left-right direction, the distance between the two first bearing seats 34 is greater than the width of the water tank 1, which can prevent the water leakage of the water tank from affecting the service life of the first bearing seats 34.

[0043] As Figures 1 to 2 shown in the figure, a water cooling unit 2 is provided on the water tank 1. The rolled piece (the workpiece to be water cooled) can pass through the water cooling unit 2 of the water tank 1 in the front-rear direction. The water cooling unit 2 can spray cooling water. The water cooling unit 2 has an annular structure. The center line of the water cooling unit 2 extends in the front-rear direction. The center line of the water cooling unit 2 is parallel to the center line of the rolled piece. The water cooling unit 2 is fixed relative to the water tank 1. The water tank 1 contains 3 to 4 channels. The water cooling units 2 of each channel are installed on the cross beam in the water tank 1. Both the water cooling unit 2 and the water tank 1 can be products of the existing technology.

[0044] The transmission mechanism includes a transmission shaft 39, a reduction gear 37, and a coupling 36. The reduction gear 37 is connected to the lifting shaft 32 in one-to-one correspondence through the coupling 36, that is, the lifting shaft 32 is connected to the coupling 36 in one-to-one correspondence, and the coupling 36 is connected to the output shaft of the reduction gear 37 in one-to-one correspondence. The axis of the coupling 36 extends in the left-right direction. The transmission shaft 39 is connected to the input shaft of each reduction gear 37.

[0045] Preferably, the speed reducer 37 is a worm gear speed reducer, and the driving device is a motor 38 with a built-in brake. The transmission shaft 39 is connected in series with the input shafts of each speed reducer 37. Each lifting shaft 32 rotates at the same angular velocity, and each eccentric wheel 35 rotates at the same angular velocity. By controlling the number of turns of the motor 38, the rotation angles of the lifting shaft 32 and the eccentric wheel 35 can be accurately controlled. Not only can the height of the water tank 1 be accurately controlled, but also the lower surface of the water tank 1 can always be kept parallel to the horizontal plane during the lifting process.

[0046] The bar water cooling device further includes a bypass roller table mechanism 6. The bypass roller table mechanism 6 is fixed on the transverse moving trolley 4. The bypass roller table mechanism 6 is located outside the left or right side of the water tank 1. The transmission mechanism is located outside the left or right side of the water tank 1. The bypass roller table mechanism 6 and the transmission mechanism are located on the same side of the water tank 1. The bypass roller table mechanism 6 includes an outer transmission roller 61. The axis of the outer transmission roller 61 extends in the left-right direction. The transmission shaft 39 extends in the front-back direction. The transmission shaft 39 is located below the outer transmission roller 61. The transmission mechanism being located outside the left or right side of the water tank 1 can prevent water leakage from the water tank from affecting the service life of the transmission mechanism.

[0047] As Figures 1 to 2 shown, the bar water cooling device further includes an inner roller table mechanism 5. The inner roller table mechanism 5 includes an inner roller shaft 51. The axis of the inner roller shaft 51 extends in the left-right direction. The inner roller shaft 51 passes through the water tank 1. Second bearing seats 52 are arranged at both ends of the left end of the inner roller shaft 51. The inner roller shaft 51 is connected to the second bearing seats 52 through bearings. The second bearing seats 52 are fixed on the transverse moving trolley 4 through support seats 53. Adjusting gaskets can be arranged between the support seats 53 and the transverse moving trolley 4 to adjust the distance between the inner roller shaft 51 and the transverse moving trolley 4. The number of adjusting gaskets can be determined as needed. Multiple adjusting gaskets can be stacked in the up-down direction.

[0048] The transverse moving trolley 4 can move in the left-right direction. The transverse moving trolley 4 includes a vehicle body, wheels and tracks connected in sequence from top to bottom. The tracks extend in the left-right direction. The vehicle body is connected with a transverse moving driving mechanism. The transverse moving driving mechanism can make the vehicle body move in the left-right direction and accurately control the position of the vehicle body in the left-right direction. The water tank 1 is located on the lifting mechanism 3. The lifting mechanism 3 is fixed on the vehicle body of the transverse moving trolley 4. The bypass roller table mechanism 6 and the inner roller table mechanism 5 are also fixed on the vehicle body of the transverse moving trolley 4. The water tank 1, the water cooling unit 2, the lifting mechanism 3, the inner roller table mechanism 5 and the bypass roller table mechanism 6 can all move left and right synchronously with the vehicle body of the transverse moving trolley 4.

[0049] During use, three such bar water cooling devices are arranged in front of the finishing mill of the bar production line, and three such bar water cooling devices are arranged behind the finishing mill, as Figure 9As shown in the figure. According to the product specifications of the production line (for example, the rolled piece is φ20mm - 90mm), the water cooling unit 2 of the bar water cooling device before the finishing mill is divided into 3 specifications, and the water cooling unit 2 of the bar water cooling device after the finishing mill is divided into 4 specifications. The diameter group distance of the rolled piece passing through each water cooling unit 2 is 10mm - 30mm. A recovery section roller path with a certain length is arranged between every two of the bar water cooling devices.

[0050] The following introduces a bar water cooling control method (which can also be called the working method of the bar water cooling device). The bar water cooling control method adopts the bar water cooling device, that is, the bar water cooling control method is implemented by the bar water cooling device. The bar water cooling control method includes the following steps:

[0051] The traversing trolley 4 moves the water tank 1 (and the lifting mechanism 3) in the left - right direction until the center line of the water cooling unit 2 is directly opposite to the center line of the rolled piece in the up - down direction (the center line of the water cooling unit 2 and the center line of the rolled piece are in the same vertical plane), and the lifting mechanism 3 moves the water tank 1 in the up - down direction until the center line of the water cooling unit 2 coincides with the center line of the rolled piece;

[0052] Or, the lifting mechanism 3 moves the water tank 1 in the up - down direction until the center line of the water cooling unit 2 is directly opposite to the center line of the rolled piece in the left - right direction (the center line of the water cooling unit 2 and the center line of the rolled piece are in the same horizontal plane), and the traversing trolley 4 moves the water tank 1 (and the lifting mechanism 3) in the left - right direction until the center line of the water cooling unit 2 coincides with the center line of the rolled piece.

[0053] The cross - section of the eccentric wheel 35 is in an annular structure. The eccentric wheel 35 contains an inner circle 351 and an outer circle 352 which are sleeved inside and outside. Both the inner circle 351 and the outer circle 352 are standard circles. The center of the inner circle 351 deviates from the center of the outer circle 352. The diameter of the inner circle 351 is equal to the diameter of the inner roller shaft 51. The inner roller shaft 51 passes through the inner circle 351, and the center of the inner circle 351 is located on the axis of the inner roller shaft 51. The connecting line between the center of the inner circle 351 and the center of the outer circle 352 is the connecting line 353. The angle α between the connecting line 353 of each eccentric wheel 35 and the up - down direction is the same, and the connecting line 353 of each eccentric wheel 35 is located in front of or behind the axis of the inner roller shaft 51 corresponding to this eccentric wheel 35.

[0054] As Figure 8As shown, during the upward rotation of the center line 353 of the eccentric wheel 35, the water tank 1 moves upward; during the downward rotation of the center line 353 of the eccentric wheel 35, the water tank 1 moves downward. When the center line 353 is in an upright state and the center of the inner circle 351 is located at the lower end of the center line 353, the water tank 1 is at the upper limit position; when the center line 353 is in an upright state and the center of the inner circle 351 is located at the upper end of the center line 353, the water tank 1 is at the lower limit position; when the center line 353 is in a horizontal state, the water tank 1 is at the middle position.

[0055] The above-mentioned lateral movement driving mechanism of the lateral movement trolley 4 can adopt a hydraulic cylinder (or a pneumatic cylinder). The axis of the hydraulic cylinder extends in the left-right direction, and the hydraulic cylinder can expand and contract in the left-right direction. By precisely controlling the expansion and contraction distance of the hydraulic cylinder, the position of the vehicle body in the left-right direction can be precisely controlled, and thus the position of the water tank 1 in the left-right direction can be precisely controlled.

[0056] As mentioned above, only the specific embodiments of the present invention are described, and the scope of the invention implementation cannot be limited by them. Therefore, the replacement of equivalent components or the equivalent changes and modifications made according to the protection scope of the present invention should still fall within the scope covered by the present invention. In addition, the technical features in the present invention, between technical features, between technical features and technical solutions, between technical solutions and technical solutions, and between embodiments and embodiments can be freely combined and used.
