Description

Technical Field

[0001] This utility model relates to the field of rolling mill guide technology, specifically a rolling mill stand inlet guide with a buffer structure. Background Technology

[0002] After the steel bar is heated to a certain degree, it can be shaped and drawn by the mold through multiple processes. In order to ensure that the steel bar travels in the correct direction and does not get stuck during the rolling process, a guide structure needs to be installed at the feed port of the equipment. The guide rollers installed on the inside can guide the steel bar into the guide and the rolling mill.

[0003] The guide rollers inside such auxiliary devices are often pre-installed according to the specifications of the steel bars. Their mobility is limited, and they cannot temporarily adjust the feeding structure in the guide according to different specifications of steel bars. If the movement is too large, it will affect the stability of the feeding, causing the steel bars to collide with the internal structure of the guide and be damaged.

[0004] Now, a novel inlet guide for a rolling mill stand with a buffer structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mill stand inlet guide with a buffer structure to solve the problem of lacking a buffer material guiding structure mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mill stand inlet guide with a buffer structure, comprising an outer shell and a cover. The cover is fixed to the right side of the outer shell, and a lower cavity is provided in the lower left corner of the cover. A gear disk I is movably connected to the front end of the lower cavity, and a gear disk II is movably connected to the rear end of the lower cavity. Lower connecting arms are fixedly connected to the top ends of the gear disk I and gear disk II, respectively. Upper connecting arms are movably connected to the front end and rear end of the upper left side of the cover, respectively. A limit wheel is movably connected between the upper connecting arm and the lower connecting arm. A motor II is fixed to the front end of the lower left corner of the bottom of the outer shell, and gaskets are fixed to the front end and rear end of the cover, respectively.

[0007] As a further technical solution of this utility model, the top of the output end of the second motor is fixedly connected to the first gear disk, and the upper connecting arm and the lower connecting arm are symmetrically and movably connected to the surface of the limiting wheel.

[0008] As a further technical solution of this utility model, a frame is fixed to both sides of the top of the outer shell, and a motor is fixed to the front end of the frame. A worm gear is movably connected between the front and rear of the left side inside the frame. A worm wheel is movably connected between the front and rear ends of the right side inside the frame. A lead screw is movably connected longitudinally to both sides of the front and rear ends inside the shell. A threaded sleeve is movably connected to the upper and lower sides of the lead screw. A guide wheel is movably connected between the front and rear sides of the outer side of the threaded sleeve. Grooves are provided on both sides of the top and bottom of the inner shell.

[0009] As a further technical solution of this utility model, the bottom of the worm gear is fixedly connected to the lead screw, the guide wheel rotates longitudinally between symmetrical threaded sleeves, and the output end of the motor is fixedly connected to the worm gear at the rear.

[0010] As a further technical solution of this utility model, a frame is fixed at the center of the bottom of the outer shell, and a column is movably connected between the front and rear of the frame. A base is fixed at the bottom of the column, and a rotating disk is fixedly connected to the front end of the column. The surface of the rotating disk is distributed with scales, and a rotating plate is fixed at the bottom of the rotating disk. A bolt is threaded into the rotating plate. A ring of screw holes is provided on the surface of the front end of the frame, and a pointer is fixed at the front end of the center of the bottom of the outer shell.

[0011] As a further technical solution of this utility model, the pointer is attached to the front end of the rotary table, and the rear of the rotary table is movably connected to the frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the inlet guide of the rolling mill stand with buffer structure not only avoids steel bar jamming and makes the material guiding space adjustable, but also makes the guide angle changeable;

[0013] (1) By moving the limit wheel between the upper connecting arm and the lower connecting arm, when the steel bar enters the cover, the bottom motor 2 is started first and the connected gear disk 1 is rotated, which forces the gear disk 1 to push the rear gear disk 2 so that the rotation direction of the gear disk 1 and the gear disk 2 are opposite. Then they are attached to the front and rear ends of the steel bar and rotate as the steel bar enters the rolling mill, providing a buffer zone for the steel bar to enter the outer shell of the guide. The limit wheel will be protected by the pad when it rotates, so as not to collide or vibrate with the cover.

[0014] (2) By connecting the guide wheel between the front and rear sides of the outer side of the threaded sleeve, the motor is started separately and the worm is rotated together. The worm pushes the two sets of worm wheels on the right side, guiding the two sets of screws connected below to rotate together. The guide wheel connected between the threaded sleeves is operated in opposite directions, and it is attached to the surface of the steel bar from the top and bottom and assists the object to pass through the outer shell and enter the rolling mill, thereby realizing the adjustment of the guiding mechanism in the guide and assisting the movement of the steel bar with the limit wheel on the right side.

[0015] (3) The frame is connected to the front and rear of the frame by a column. The shell connected to the frame is rotated above the column. The rotating disk fixed at the front end of the column rotates with the surface of the frame. By observing the pointer, the scale can be indicated and the tilt angle of the shell can be known. Then, the rotating plate and the screw hole are aligned and the bolt is screwed in to fix it. This can prevent the shell from shaking and can also adjust its bearing state according to the direction and angle of the steel bar entering the guide. Attached Figure Description

The front end of the lower cavity 12 is movably connected to a toothed disc 8, and the rear end of the lower cavity 12 is movably connected to a toothed disc 19. The top ends of the toothed disc 8 and the toothed disc 19 are respectively fixedly connected to a lower connecting arm 11. The front end and the rear end of the upper left side of the cover 9 are respectively movably connected to an upper connecting arm 7. A limit wheel 10 is movably connected between the upper connecting arm 7 and the lower connecting arm 11. The front end of the lower left corner of the bottom of the shell 1 is fixed to a motor 13, and the front end and the rear end of the cover 9 are respectively fixed to a gasket 18.

[0023] The top of the output end of motor 213 is fixedly connected to gear disc 18, and the upper connecting arm 7 and the lower connecting arm 11 are symmetrically and movably connected to the surface of limit wheel 10.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, when the steel bar enters the cover 9, the bottom motor 13 is started first and the connected gear disk 8 is rotated, which forces the gear disk 8 to push the rear gear disk 19 so that the gear disk 8 and the gear disk 19 rotate in opposite directions. Then they are attached to the front and rear ends of the steel bar and rotate as the steel bar enters the rolling mill, providing a buffer zone for the steel bar to enter the outer shell 1 of the guide. The limit wheel 10 will be protected by the gasket 18 when it rotates.

[0025] A frame 4 is fixed to both sides of the top of the outer shell 1, and a motor 5 is fixed to the front end of the frame 4. A worm 20 is movably connected between the front and back of the left side inside the frame 4. A worm wheel 22 is movably connected between the front and rear ends of the right side inside the frame 4. A lead screw 3 is movably connected longitudinally to both sides of the front and rear ends inside the outer shell 1. A threaded sleeve 6 is movably connected to the top and bottom of the lead screw 3. A guide wheel 2 is movably connected between the front and back of the outer side of the threaded sleeve 6. Grooves 21 are provided on both sides of the top and bottom of the inner shell 1. The bottom of the worm wheel 22 is fixedly connected to the lead screw 3. The guide wheel 2 rotates longitudinally between the symmetrical threaded sleeves 6. The output end of the motor 5 is fixedly connected to the worm 20 at the rear.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the motor 5 is started separately and the worm gear 20 is rotated. The worm gear 20 pushes the two sets of worm wheels 22 on the right side, guiding the two sets of lead screws 3 connected below to rotate together. The guide wheels 2 connected between the threaded sleeves 6 are operated in opposite directions and are attached to the surface of the steel bar from the top and bottom, assisting the object to pass through the outer shell 1 and enter the rolling mill, thereby realizing the adjustment of the guiding mechanism in the guide.

[0027] A frame 14 is fixed at the center of the bottom of the outer shell 1, and a column 16 is movably connected between the front and rear of the frame 14. A base 17 is fixed at the bottom of the column 16, and a rotating disk 15 is fixedly connected to the front end of the column 16. The surface of the rotating disk 15 is distributed with scales 23. A rotating plate 26 is fixed at the bottom of the rotating disk 15, and a bolt 25 is threaded into the rotating plate 26. A ring of screw holes 24 is provided on the surface of the front end of the frame 14. A pointer 27 is fixed at the front end of the center of the bottom of the outer shell 1.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the outer shell 1 connected to the frame 14 is rotated above the column 16. The rotating disk 15 fixed at the front end of the column 16 rotates with the surface of the frame 14. By observing the direction of the pointer 27, the scale 23 can be indicated and the tilt angle of the outer shell 1 can be known. Then, the rotating plate 26 and the screw hole 24 are aligned, and the bolt 25 is screwed in to fix it, which can prevent the outer shell 1 from continuing to shake.

[0029] Working principle: When using this utility model, firstly, rotate the outer shell 1 connected to the frame 14 above the column 16. The rotating disk 15 fixed to the front end of the column 16 will rotate with the surface of the frame 14. Observe the direction of the pointer 27 to indicate the scale 23 and know the tilt angle of the outer shell 1. Then align the rotating plate 26 with the screw hole 24, screw in the bolt 25 to fix it, which can prevent the outer shell 1 from continuing to shake. When the steel bar enters the cover 9, first start the bottom motor 13 and rotate the connected gear disk 8, forcing the gear disk 8 to push the rear gear disk 19, so that the gear disk 19... 8 rotates in the opposite direction to the toothed disc 19, and then they are attached to the front and rear ends of the steel bar. As the steel bar enters the rolling mill, they rotate, providing a buffer zone for the steel bar to enter the guide housing 1. The limit wheel 10 will be protected by the gasket 18 when it rotates. Finally, the motor 5 is started separately and the worm 20 is rotated. The worm 20 pushes the two sets of worm wheels 22 on the right side, guiding the two sets of lead screws 3 connected below to rotate together. The guide wheel 2, which is movably connected between the threaded sleeves 6, is attached to the surface of the steel bar from both the top and bottom and assists the bar to pass through the housing 1 and enter the rolling mill.
