Description

Technical Field

[0001] This utility model relates to the field of steel ingot rolling technology, and in particular to a steel ingot turning mechanism for a rolling mill. Background Technology

[0002] A rolling mill is a mechanical device that realizes the metal rolling process. It generally refers to the equipment that completes the entire process of rolling production. After processing, steel ingots need to enter the rolling mill for rough rolling. Before rough rolling, the steel ingots need to be flipped so that they enter the rough rolling mill in a billet form.

[0003] A search revealed Chinese Patent Publication No. CN217534441U, which discloses a steel ingot turning device for a rolling mill. The device controls the start and stop of the drive motor via a control panel. The output end of the drive motor drives the lead screw to rotate in both directions. The rotation of the lead screw drives the threaded block to move left and right. Under the action of the movable rod, one end of the flip plate is lifted upward and flipped 90 degrees, thereby enabling the turning of steel ingots in multiple grooves.

[0004] However, the surface of the steel ingot may have slag, and direct rolling may cause indentations on the surface of the steel ingot, affecting the quality of the steel ingot. Utility Model Content

[0005] The purpose of this utility model is to provide a steel ingot turning mechanism for a rolling mill in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A steel ingot turning mechanism for a rolling mill includes a base, a first vertical plate and a second vertical plate fixedly connected to the top of the base, the second vertical plate being located in front of the first vertical plate, and multiple sets of conveying rollers rotatably connected between the first and second vertical plates. A limit assembly is provided on the front side of the first vertical plate, and an electric push rod is fixedly connected to the front side of the second vertical plate. A slide block is fixedly connected to the output end of the electric push rod, and the slide block is slidably connected to the top of the base. Multiple sets of turning assemblies are provided on the slide block, and the turning assemblies are spaced apart between two adjacent conveying rollers. A striking mechanism is provided above the turning assemblies. The striking mechanism includes a slide rod slidably connected to the wall of the second vertical plate, a mounting plate fixedly connected to the rear end of the slide rod, a plurality of striking hammers fixedly connected to the rear side of the mounting plate, a baffle fixedly connected to the front end of the slide rod, and a spring fixedly connected between the baffle and the second vertical plate.

[0009] Preferably, the limiting component includes a protruding plate fixedly connected to the front side of the first vertical plate, the protruding plate being located above the conveying roller.

[0010] Preferably, the front side of the convex plate is provided with an installation groove, and several rotating rollers are rotatably connected in the installation groove.

[0011] Preferably, the end of the striking hammer is spherical.

[0012] Preferably, the flipping assembly includes a hinge seat fixedly connected to the top of the slide, a clamping plate rotatably connected between the hinge seats, the clamping plate being U-shaped, a hydraulic cylinder hinged between the bottom of the clamping plate and the top of the slide, and a limit plate fixedly connected between the hinge seats, the limit plate being located in front of the hydraulic cylinder.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a steel ingot turning mechanism for a rolling mill includes a base 1. A first vertical plate 101 and a second vertical plate 102 are bolted to the top of the base 1. The second vertical plate 102 is located in front of the first vertical plate 101. Multiple sets of conveying rollers 2 are rotatably connected between the first vertical plate 101 and the second vertical plate 102. A drive motor is bolted to the front side of the second vertical plate 102. The output end of the drive motor is connected to one of the conveying rollers 2 through a coupling. Adjacent conveying rollers 2 are driven by pulleys and belts. When the drive motor is started, one of the conveying rollers 2 is driven to rotate, and the other conveying rollers 2 are driven to rotate synchronously through the transmission between the pulleys and belts.

[0027] A limiting component is provided on the front side of the first vertical plate 101. The limiting component includes a protruding plate 3 fixedly connected to the front side of the first vertical plate 101. The protruding plate 3 is located above the conveying roller 2. An installation groove is opened on the front side of the protruding plate 3. Several rotating rollers 301 are rotatably connected in the installation groove to push the steel ingot onto the protruding plate 3 and limit the steel ingot, so as to facilitate the flipping of the steel ingot. By setting the rotating rollers 301, the friction between the steel ingot and the protruding plate 3 is reduced when the steel ingot is flipped.

[0028] An electric push rod 401 is fixedly connected to the front side of the second vertical plate 102. A slide 402 is fixedly connected to the output end of the electric push rod 401. The slide 402 is slidably connected to the top of the base 1. Multiple sets of flipping components are provided on the slide 402. The flipping components are spaced apart between two adjacent conveying rollers 2. The flipping component includes a hinge seat 403 fixedly connected to the top of the slide 402. A clamping plate 404 is rotatably connected between the hinge seats 403. The clamping plate 404 is U-shaped. A hydraulic cylinder 405 is hinged between the bottom of the clamping plate 404 and the top of the slide 402. A limit plate 406 is fixedly connected between the hinge seats 403. The limit plate 406 is located in front of the hydraulic cylinder 405.

[0029] A striking mechanism is provided above the flipping assembly. The striking mechanism includes a slide rod 501 slidably connected to the wall of the second vertical plate 102. A mounting plate 502 is fixedly connected to the rear end of the slide rod 501. Several striking hammers 503 are fixedly connected to the rear side of the mounting plate 502. The ends of the striking hammers 503 are spherical. A baffle 504 is fixedly connected to the front end of the slide rod 501. A spring 505 is fixedly connected between the baffle 504 and the second vertical plate 102.

[0030] The striking mechanism also includes a power assembly for driving the baffle 504 to move forward. The power assembly includes a horizontal plate 506 bolted to the front side of the second vertical plate 102. A rotary motor 507 is bolted to the bottom of the horizontal plate 506. A cam 508 is fixedly connected to the output shaft of the rotary motor 507. During the rotation of the cam 508, it abuts against the baffle 504, starting the rotary motor 507, which drives the cam 508 to rotate.

[0031] Working principle: During use, the steel ingot is conveyed to the appropriate position by the conveyor roller 2. The slide 402 is moved by controlling the electric push rod 401. After the clamping plate 404 clamps the steel ingot, the clamping plate 404 pushes the steel ingot to continue moving until the steel ingot hits the protrusion plate 3. The hydraulic cylinder 405 is controlled to rotate the clamping plate 404 90 degrees around the hinge seat 403, thereby flipping the steel ingot. After the steel ingot is flipped into a billet shape, the rotary motor 507 is started. The rotary motor 507 drives the cam 508 to rotate. When the tip of the cam 508 abuts against the baffle 504, the cam 508 drives the baffle 504 to rotate. The slide bar 501 moves forward, and the spring 505 stores energy. When the tip of the cam 508 rotates away, the baffle 504, under the elastic force of the spring 505, drives the slide bar 501 to move the mounting plate 502 and the hammer 503 backward quickly, striking the steel ingot and causing it to vibrate. This knocks off the slag on the surface of the steel ingot, ensuring the quality of the rolled steel ingot. Then, the steel ingot is transported to the rolling mill for rough rolling via the conveyor roller 2. After the steel ingot is removed, the clamping plate 404 flips back to the horizontal position. Then, the electric push rod 401 drives the slide block 402 to move, so that the clamping plate 404 is reset for the next use.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
