Description

Technical Field

[0001] The utility model relates to the technical field of metal plate leveling equipment, in particular to a metal plate leveling machine. Background Art

[0002] A metal sheet leveler, also known as a leveler or flattener, is a mechanical equipment used to level uneven metal sheets. It uses the rotating motion of rollers to process the metal sheets to be processed into flat sheets or specific shapes. It can effectively solve the problem of uneven metal sheets and improve product quality and production efficiency. It is widely used in machinery, metallurgy, building materials, chemicals, electronics, electricity, light industry and other industries. However, in order to prevent the metal sheets from skewing or getting stuck on the leveler, most of the existing levelers will have two sets of symmetrically distributed limit rods at the feed inlet. By adjusting the distance between the limit rods on both sides, the limit rods on both sides are clamped on both sides of the metal sheet to limit the position of the metal sheet and ensure the stability of the metal sheet entering the leveler.

[0003] However, when the limit rods are installed at the feeding port of the leveling machine for use, the two groups of symmetrically distributed limit rods will occupy the position of the feeding mechanism, separating the feeding mechanism and the leveling machine, and it is necessary to separately set a conveying roller between the limit columns on both sides to convey the metal sheet, which is more troublesome. In addition, since most of the existing limit columns are formed of high-hardness steel in one piece, the limit columns rub against the metal sheet for a long time, which will not only scratch the surface of the limit column, but also easily cause the metal sheet to wear, affecting the quality of the metal sheet and the use of the limit column. Therefore, those skilled in the art provide a metal sheet leveling machine to solve the problems raised in the above background technology. Utility Model Content

[0012] Preferably, two symmetrically distributed support plates are provided at one end of the extension frame close to the leveling machine body, and a slot is provided on one side of the extension frame between the two support plates. The extension frame is mounted on the outside of the leveling machine body through the slot, and limiting bolts are provided at the four corners of the support plates.

[0027] In one embodiment, when the limiting rod 3 is installed on the driving seat 23 for use, the inner rod 31 can be firstly sleeved on the outside of the threaded rod 26, so that the inner rod 31 is engaged with the outside of the limiting spline 25 through the spline groove 311, and at the same time, the threaded rod 26 is extended to the second thread groove 312 inside the inner rod 31, and then the wear-resistant sleeve 32 is sleeved on the outside of the inner rod 31, so that the wear-resistant sleeve 32 surrounds the outer wall of the inner rod 31 to protect it, and finally, the threaded barrel 34 is threadedly installed in the second thread groove 312, and the threaded barrel 34 is passed through the third thread groove 312. The 41 thread is installed on the outer wall of the threaded rod 26, and the end plate 33 is pressed tightly against the top of the wear-resistant sleeve 32 to limit the position of the wear-resistant sleeve 32, thereby completing the installation of the limit rod 3. The limit rod 3 can be installed in the gap between the conveying rollers 21. By changing the installation position of the limit rod 3, the use of the limit rod 3 can be ensured without affecting the conveying of the metal sheet, avoiding the trouble of separately setting the conveying rollers 21 between the limit rods 3 on both sides to convey the metal sheet, ensuring the conveying of the metal sheet, improving the stability of the metal sheet conveying, and having strong practicality.

[0029] The working principle of the utility model is as follows: when using a leveling machine to level a metal sheet, the metal sheet can be first placed on two conveying rollers 21 in the extension frame 2 and located between two groups of symmetrically distributed limit rods 3, and then the screw rod 22 is driven by the rotating wheel 27 to rotate inside the extension frame 2, and then the rotating screw rod 22 drives the two drive seats 23 installed on its outer wall through the first thread groove 231 to move, so that the two drive seats 23 are displaced toward each other inside the extension frame 2 through the cooperation of the slider 232 and the slide groove 201, and then the displaced toward each other The two driving seats 23 drive the limit rods 3 installed thereon to move, and adjust the distance between the two limit rods 3 so that the size of the clamping groove between the two limit rods 3 is adapted to the width of the metal sheet. The position of the metal sheet is limited by the two sets of limit rods 3 after adjusting the position to prevent the metal sheet from being skewed. Finally, the metal sheet is transported from the feed port 101 into the leveling machine through the conveying rollers 21, and the metal sheet is squeezed and leveled by the two squeezing rollers inside the leveling machine, thereby changing the installation position of the limit rods 3, so that the conveying of the metal sheet can be prevented without affecting the In this case, the use of the limit rod 3 is ensured, and the trouble of separately setting the conveying roller 21 between the limit rods 3 on both sides to convey the metal sheet is avoided. The conveying of the metal sheet is ensured, the stability of the metal sheet conveying is improved, and the practicability is strong. In addition, when the limit rod 3 is used to limit the position of the metal sheet, the wear-resistant sleeve 32 on the limit rod 3 can contact the metal sheet, and the metal sheet will not be directly contacted with the inner rod 31 made of high-hardness steel, thereby avoiding the metal sheet being directly contacted with the inner rod 31 of high-hardness steel. The wear-resistant sleeve 32 is easily removed from the inner rod 31 by screwing the end plate 33, and the wear-resistant sleeve 32 is pulled out from the outer wall of the inner rod 31 to complete the replacement of the wear-resistant sleeve 32.
