Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, and more specifically, to a steel strip calendering and flattening machine. Background Art

[0002] Steel strip calendering and leveling machinery is a kind of equipment used for calendering and leveling steel strips. It squeezes and stretches the steel strips through a series of rollers to achieve the purpose of calendering. At the same time, leveling rollers with different precisions are used to eliminate the bending, waves and other unevenness of the steel strips, making the surface of the steel strips smoother and the thickness more uniform.

[0003] The existing steel strip calendering and leveling machinery needs to install and disassemble the coil roller when working. During the installation and disassembly operations of the coil roller, multiple screws need to be turned to operate. This operation method is too cumbersome and greatly affects the processing progress.

[0004] After searching, the Chinese patent with authorization announcement number CN213915540U discloses a method of calendering an armored steel strip.

[0005] The leveling machine starts the motor through an external power supply. The motor drives the square rod to rotate in the inner cavity of the second bearing. At the same time, the square rod drives the column to rotate in the inner cavity of the first bearing. The square rod drives the coiling roller to rotate to collect the material. The steel strip body is subjected to S-shaped alternating stress between two adjacent second winding rollers. At the same time, the steel strip body is subjected to U-shaped alternating stress between several first winding rollers. When the coiling roller reaches a saturated state, the motor is stopped and the pull ring is pulled upward. The pull ring drives the insertion rod to move away from the blind hole. and the fixed plate to release the fixation of the horizontal plate and the movable plate, and then move the horizontal plate to the rear side, the horizontal plate drives the frame to move on the outer edge of the U-shaped plate, and at the same time the horizontal plate drives the roller to roll on the top of the bottom plate, the horizontal plate drives the movable plate to move away from the coiling roller, the movable plate drives the column to move away from the square rod, and then flip the movable plate to the rear side, the movable plate flips around the center of the pin shaft, and then moves the coiling roller to the rear side, the coiling roller moves on the square rod, thereby completing the disassembly of the coiling roller, and the operation method for installing the coiling roller is the opposite of the above.

[0006] However, in actual use, due to the different proficiency of the staff in replacing the coil roller, and when replacing the coil roller, there is only one coil roller, the calendering and leveling machine cannot continue to calender and level the steel strip, but reduces the work efficiency.

[0026] Technical effects and advantages of the utility model:

[0027] 1. By setting up a coiling mechanism, the first hydraulic cylinders on both sides are started to push the first hydraulic rod, and the first hydraulic rod pushes the spliced ​​rotating shaft through the third fixed ring to the inside of the coiling roller.

Because a fixed plate is provided at the bottom of the coiling roller and it is composed of two arc plates, and because the surface of the arc plate is A rotating rod is installed. When the coiling roller rotates, the fixed plate plays a certain supporting role. The rotating rod will rotate with the rotation of the coiling roller, reducing the friction between the coiling roller and the mechanism itself, thereby preventing the device from tilting due to the influence of tension and rotating the lower coiling roller to the upper side to continue working. At this time, the lower coiling roller is replaced.

In addition, the device rotates through the movement of the steel strip in the calendering and leveling machine, which also reduces the cost consumption;

[0028] 2. By setting up a feeding roller mechanism, the coiled material roller wrapped with the steel strip is transported to the clamping plate of the feeding roller mechanism, and the second hydraulic cylinder is started. The second hydraulic cylinder pushes the second hydraulic rod to move upward, and the second hydraulic rod pushes the connecting rod to move upward. The connecting rod pushes the first mounting ring, the second mounting ring and the second connecting rod to move upward. Because the first mounting ring moves upward, the first mounting ring drives the first connecting rod, the rotating shaft and the sliding ring to slide in the positioning sliding hole on the surface of the fixed seat and the rotating shaft rotates, so the clamping plate, the fixed rod and the coiled material roller are sent upward to a certain position. Compared with the prior art, this method is more labor-saving and convenient when replacing the coiled material roller, and reduces time cost. BRIEF DESCRIPTION OF THE DRAWINGS

The slip ring 21 and the positioning slide hole 20 are provided because the downward movement of the first connecting rod 23 follows an arc-shaped motion trajectory. If it is to move downward to a horizontal position, it needs to move backward at the same time. A rotating shaft 22 is rotatably provided inside the slip ring 21, and a first connecting rod 23 is fixedly provided outside the rotating shaft 22.

[0044] In some embodiments, according to Figure 5 As shown, a first mounting ring 24 is fixedly provided at one end of the first connecting rod 23, a connecting rod 25 is fixedly provided between the two first mounting rings 24, a second hydraulic cylinder 26 is fixedly provided on the top of the base 2, a second hydraulic rod 27 is provided at the output end of the second hydraulic cylinder 26, and the second hydraulic rod 27 is fixedly connected to the connecting rod 25. The second hydraulic cylinder 26 and the second hydraulic rod 27 are provided to push the connecting rod 25 upward or pull the connecting rod 25 downward to enable the roller feeding mechanism to operate.

[0045] In some embodiments, according to Figure 5 As shown, two second mounting rings 28 are fixedly provided on the outer side of the connecting rod 25, and the two second mounting rings 28 are arranged between the first mounting rings 24. A support block 29 is fixedly provided on the bottom of the second mounting ring 28. The support block 29 is provided to support the first connecting rod 23 when it moves downward. A second connecting rod 30 is fixedly provided on the top of the second mounting ring 28, and a clamping plate 31 is fixedly provided on one end of the second connecting rod 30.

[0046] The working principle of the utility model is as follows: when the steel strip 12 needs to be calendered and leveled, in the preparation stage, the staff transports the coil roll 11 wound with the steel strip 12 to the clamping plate 31 of the roller feeding mechanism, starts the second hydraulic cylinder 26, the second hydraulic cylinder 26 pushes the second hydraulic rod 27 to move upward, the second hydraulic rod 27 pushes the connecting rod 25 to move upward, the connecting rod 25 pushes the first mounting ring 24, the second mounting ring 28 and the second connecting rod 30 to move upward, because the first mounting ring 24 moves upward, the first mounting ring 24 is brought The first connecting rod 23, the rotating shaft 22 and the slip ring 21 slide in the positioning sliding hole 20 on the surface of the fixed seat 19 and the rotating shaft 22 rotates, so that the clamping plate 31, the fixed rod and the coiling roller 11 are sent upward to a certain position, and then the first hydraulic cylinders 7 on both sides are started to push the first hydraulic rod 8, and the first hydraulic rod 8 pushes the spliced ​​rotating shaft 10 through the third fixed ring 9 to the inside of the coiling roller 11, and then the staff rotates the gripping rod 18 inside the second installation groove 17 to adjust 180° and repeats the above operation to install the second coiling roller 11, and then start working;

[0047] When the work starts, after one end of the steel strip 12 wound on the upper coiling roller 11 is fed into the calendering and leveling machine 1, the device operates. Because the steel strip 12 continues to move forward in the calendering and leveling machine 1, the coiling roller 11 also rotates due to the movement of the steel strip 12. Because a fixed plate composed of two arc plates 14 is fixed between the fixed blocks 6, and a rotating rod 16 is installed on the inner side of the mounting groove on the surface of the arc plate 14, the rotation of the coiling roller 11 will drive the rotating rod 16 to rotate, so as to reduce friction and improve structural rigidity;

[0048] When the coiling roller 11 needs to be replaced, the staff member holds the grip and rotates it 180°. Since the first fixing ring 4 is rotatably connected to the support frame 3, it can rotate. At this time, the coiling roller 11 below is turned to the top to continue to work. The second hydraulic cylinder 26 is started to repeat the above-mentioned roller feeding work, and the clamping plate 31 is aligned with both sides of the coiling roller 11. The first hydraulic cylinder 7 is started to pull the first hydraulic rod 8. The first hydraulic rod 8 pulls the splicing rotating shaft 10 out of the inside of the coiling roller 11 to the outside of the first fixing ring 4. Then the coiling roller 11 contacts the clamping plate 31, and the second hydraulic cylinder 26 pulls the first hydraulic rod 8. The pressure rod 8 moves downward, and the first hydraulic rod 8 pulls the connecting plate, the first mounting ring 24 and the second mounting ring 28 to move downward. The second mounting ring 28 moves downward, so the second connecting rod 30, the clamping plate 31 and the winding roller 11 move downward. Because the first mounting ring 24 moves downward, the first connecting rod 23 moves downward, the rotating shaft 22 rotates, and the slip ring 21 slides to a certain position along the positioning slide hole 20 because of the downward movement of the first connecting rod 23 until the support block 29 contacts the base 2. At this time, the working group personnel replace the winding roller 11 and then repeat the roller feeding work to complete the replacement.
