Description

Technical Field

[0001] The invention belongs to the technical field of steel processing, in particular to a shaping device for steel processing. Background Art

[0002] During the production process, the steel plate may be bent, warped or deformed due to factors such as heat treatment, rolling or cooling. Leveling is to correct these deformations and restore the steel plate to a flat state to meet the requirements of subsequent processing and use.

[0003] Common multi-roller leveling machines use multiple corrective rollers. By controlling the gap and pressure between the rollers, the steel plate is continuously bent when passing through these rollers, and the stress generated during the leveling process is released while the plate is leveled. However, during the leveling process, the plate can only bend in the direction of the corrective roller setting, resulting in incomplete stress release after the plate is leveled. The plate after leveling will bend and rebound in a manner perpendicular to the corrective roller, affecting the flatness of the plate after leveling. The usual way to solve this problem is to change the direction of the plate (rotate 90 degrees compared to the first leveling direction) and put it into the leveling machine again for leveling. However, this process requires moving the plate from the discharge position to the feed position again. Not only is the process cumbersome, but it also puts a heavy physical burden on the staff, making it difficult to improve the efficiency of steel plate leveling.

DETAILED DESCRIPTION

[0028] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] like Figure 1-6 As shown, the present invention provides a shaping device for steel processing, comprising a frame 1, a shaping mechanism 2 and a driving mechanism 3 are arranged on the top of the frame 1, and a reversing mechanism 4 is arranged on one side of the shaping mechanism 2 on the top of the frame 1;

[0030] The orthopedic mechanism 2 includes two fixed frames 201 arranged opposite to each other on the top of the frame 1, which are composed of two vertically arranged uprights 2011 and a horizontal crossbar 2012, and the two uprights 2011 and the crossbar 2012 are arranged in an H shape, and two movable rods 202 are arranged between the two uprights 2011 on the upper and lower sides of the crossbar 2012, and the two ends of the movable rod 202 are respectively connected to the two uprights 2011 in a sliding manner. The orthopedic mechanism 2 also includes a first rotating shaft 203 and a second rotating shaft 204 installed between the two fixed frames 201, and the two ends of the first rotating shaft 203 are respectively connected to the two uprights 2011. The cross bars 2012 of the two fixed frames 201 are rotatably connected, and the second rotating shafts 204 have two groups, and the two ends of one group of second rotating shafts 204 are rotatably connected with the two movable rods 202 located below the cross bars 2012, and the two ends of the other group of second rotating shafts 204 are rotatably connected with the two movable rods 202 located above the cross bars 2012. The surfaces of the first rotating shaft 203 and the second rotating shaft 204 are respectively provided with a first orthopedic roller 205 and a second orthopedic roller 206, and the tops of the two fixed frames 201 are both provided with a top rod 207, and the top of the top rod 207 is installed with a distance adjustment component 5;

[0031] There are multiple first rotating shafts 203 , which are equidistantly distributed in the transverse direction, and the second rotating shafts 204 and the first rotating shafts 203 are staggered in the transverse direction.

[0032] The plate first passes between the first corrective roller 205 and a set of second corrective rollers 206 located above. When passing through the first corrective rollers 205 and the second corrective rollers 206, it will bend repeatedly to eliminate the stress generated in the straightening process along the direction of movement of the plate. After that, the direction of the plate is changed by the reversing mechanism 4, and the plate passes between the first corrective roller 205 and the second corrective roller 206 located below, thereby eliminating the stress of the plate in the direction perpendicular to the above direction, thereby reducing the possibility of rebound and re-bending of the steel plate.

[0033] The reversing mechanism 4 includes two pairs of guide rods 401 fixedly arranged on the top of the frame 1 and a lifting plate 402 installed between the two pairs of guide rods 401. The lifting plate 402 is slidably connected to the four guide rods 401. A turntable 403 is rotatably installed in the middle of the lifting plate 402. The reversing mechanism 4 also includes a reversing sleeve 404 arranged on the top of the frame 1 and a reversing rod 405 fixedly arranged at the bottom center of the turntable 403. A reversing groove 406 is provided on the surface of the reversing sleeve 404. The bottom end of the reversing rod 405 penetrates into the reversing sleeve 404, and a reversing pin 407 is provided on the surface of one end of the reversing rod 405. The reversing pin 407 penetrates into the reversing groove 406.

[0034] Among them, the reversing groove 406 consists of two parts, the upper part is spirally arranged on the surface of the reversing sleeve 404, and the angle formed between the projections of the two ends of the spiral part on the horizontal plane and the center of the reversing sleeve 404 is 90 degrees, so that when the reversing pin 407 moves in the reversing groove 406, the reversing rod 405 can be rotated 90 degrees, and the lower part of the reversing groove 406 is vertical.

[0035] The tops of the two pairs of guide rods 401 are commonly connected to a top plate 408 , and an electric push rod 409 is fixedly installed on the top of the top plate 408 . The pushing end of the electric push rod 409 penetrates the top plate 408 and is fixedly connected to the lifting plate 402 .

[0036] After the plate passes through the first correction between the first correction roller 205 and the second correction roller 206 located above, it will be sent to the top of the turntable 403. After that, the electric push rod 409 is started to push the lifting plate 402 to move downward. During the movement of the lifting plate 402, the turntable 403 is driven to move downward. When the turntable 403 moves, it will drive the reversing rod 405 to move downward in the reversing sleeve 404, so that the reversing pin 407 provided on the reversing rod 405 moves along the reversing groove 406, and then the reversing rod 405 rotates 90 degrees during the movement, so that the turntable 403 drives the plate to rotate 90 degrees, and at the same time, the steel plate moves down between the first correction roller 205 and the second correction roller 206 located below, so as to correct the plate from another direction.

[0037] Among them, the driving mechanism 3 includes a gear box 301 fixedly arranged on the top of the frame 1, and multiple first gears 302 are installed inside the gear box 301. One end of each first rotating shaft 203 penetrates into the gear box 301 and is fixedly connected to the first gear 302. A second gear 303 is also installed between two adjacent first gears 302 in the gear box 301, and the second gear 303 is meshed and connected with each first gear 302 of the chain located on both sides thereof. The driving mechanism 3 also includes a first motor 304 installed on the frame 1, and the output end of the first motor 304 is connected to one of the first rotating shafts 203 through a belt drive.

[0038] The first motor 304 drives one of the first rotating shafts 203 to rotate through a belt, and the first rotating shaft 203 drives each first rotating shaft 203 to rotate synchronously through the first gear 302 and the second gear 303 in turn, thereby driving each first corrective roller 205 to rotate, providing power for the steel plate to pass between the first corrective roller 205 and the second corrective roller 206.

[0039] Among them, a mounting groove 4031 is opened on the top of the turntable 403, and a mounting frame 4032 is installed inside the mounting groove 4031. A plurality of conveying rollers 4033 are equidistantly installed on the top of the mounting frame 4032, and two adjacent conveying rollers 4033 are connected by belt transmission. A second motor 4034 is also fixedly installed on one side of the mounting frame 4032, and the output end of the second motor 4034 is transmission-connected to one of the conveying rollers 4033.

[0040] Among them, a sliding rod 4035 is arranged at the bottom of the mounting frame 4032, the sliding rod 4035 passes through the turntable 403, and a buffer block 4036 is arranged at the bottom. The top of the buffer block 4036 is made of rubber material, which is used to alleviate the rigid impact on the top of the rack 1, thereby increasing the life of the buffer block 4036 and reducing the noise generated when the buffer block 4036 contacts the rack 1.

[0041] After the reversing pin 407 passes through the spiral part of the reversing groove 406, the turntable 403 and the mounting frame 4032 rotate 90 degrees at the same time, and the buffer block 4036 just contacts the top plane of the frame 1. After that, the electric push rod 409 continues to push the lifting plate 402 downward, so that the reversing pin 407 moves in the vertical part of the reversing groove 406, and the lifting plate 402 continues to drive the turntable 403 downward. However, the buffer block 4036 is blocked by the frame 1, and the mounting frame 4032 cannot move further downward, so it will drive each conveying roller 4033 to protrude from the surface of the turntable 403 and lift the steel plate. After that, the second motor 4034 starts to drive each conveying roller 4033 to rotate, so as to convey each steel plate to between the first corrective roller 205 and each second corrective roller 206 located below, and perform secondary leveling of the plate.

[0042] The pitch adjustment assembly 5 includes two pairs of mounting boxes 501 fixedly arranged on the top of the two top rods 207, a driving rod 502 is arranged between each pair of mounting boxes 501, the end of the driving rod 502 penetrates into the mounting box 501 and the penetrated end is fixedly connected to a worm 503, a worm wheel 504 is also installed in the mounting box 501, and the worm wheel 504 is meshed with the worm 503, one end of one of the worms 503 penetrates from one side of the mounting box 501, and the penetrated end is connected to a hand wheel 505, and the center of the worm wheel 504 penetrates A bidirectional threaded rod 506 is provided, the bottom end of which passes through the installation box 501 and sequentially penetrates the top rod 207, the movable rod 202 located above the cross bar 2012, the cross bar 2012, and the movable rod 202 located below the cross bar 2012, and the bottom end is rotatably connected to the frame 1, the bidirectional threaded rod 506 is rotatably connected to the cross bar 2012, and the two movable rods 202 located above the cross bar 2012 and below the cross bar 2012 are respectively threadedly connected to the threads on the surface of the bidirectional threaded rod 506 in different directions.

[0043] Among them, the pitch adjustment component 5 also includes a gear box 507 installed in the middle of the two driving rods 502 and a transmission rod 508 installed between the two gear boxes 507. The two ends of the transmission rod 508 are respectively inserted into the two gear boxes 507, and the inserted end is connected to the driving rod 502 through a bevel gear transmission.

[0044] The worm 503 is driven to rotate by rotating the hand wheel 505, and the worm 503 drives the driving rod 502 and the worm 503 located at the other end of the driving rod 502 to rotate. The two worms 503 drive one pair of worm wheels 504 to rotate, so that two of the two-way threaded rods 506 are rotated. During the rotation of the driving rod 502, the transmission rod 508 is driven to rotate through the bevel gear, and the transmission rod 508 drives another driving rod 502 to rotate through the bevel gear. The driving rod 502 then drives the other two worms 503 to rotate, so that the other two worm wheels 504 drive the other two two-way threaded rods 506 to rotate, and then the four two-way threaded rods 506 keep rotating synchronously. During the rotation of the two-way threaded rod 506, the two movable rods 202 threadedly connected with the threads in different directions on the surface of the two-way threaded rod 506 will move upward and downward respectively, thereby changing the distance between the two sets of second orthopedic rollers 206 and the first orthopedic roller 205, so as to facilitate the passage of plates of different thicknesses, thereby facilitating the leveling of plates of different thicknesses.
