Description

Technical Field

[0001] The utility model relates to the technical field of steel coil production, in particular to a leveling mechanism of a steel coil cross-cutting machine. Background Art

[0002] The cross-cutting machine is a mechanical equipment. During the steel plate production process, it is responsible for cutting the steel strip into pieces of steel plates. Since the steel strip is coiled, it needs to be leveled using a leveling mechanism during the conveying process to ensure the flatness of the steel strip after entering the cross-cutting machine.

[0003] Authorization announcement No. CN217451568U discloses a leveling device for stainless steel coil processing, including a frame, a support plate for placing steel plates is fixedly installed on the upper surface of the frame, and two limit plates are slidably connected to the upper edge of the support plate in the longitudinal direction, and a driving mechanism for driving the two limit plates to move toward or in the opposite direction is fixedly installed on the frame to increase the relative distance between the two limit plates; the driving mechanism can increase or decrease the relative distance between the two limit plates according to the width of the stainless steel coil, thereby avoiding the problem of offset of the stainless steel coil during the feeding process, and can absorb magnetic impurities such as bolts that fall on the stainless steel coil through a magnet bridge, and a cleaning device can prevent impurities from entering the interior of the leveling device along with the stainless steel coil, thereby effectively avoiding the problem of local depression of the leveled product due to impurities on the stainless steel coil.

[0004] The existing steel coil flattening mechanism can flatten and clean the steel strip, but when the steel strip is conveyed to the end, the two ends of the steel strip are concave to a large extent. Therefore, directly pressing down the steel strip may cause the ends of the steel strip to fold, affecting its use. Summary of the invention

[0005] The main purpose of the utility model is to provide a leveling mechanism for a steel coil cross-cutting machine, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A leveling mechanism for a steel coil cross-cutting machine comprises a base, a vertical plate welded at one end of the base, an electric cylinder is mounted on one side of the vertical plate via a fixing rod and bolts, a pressure plate is mounted on the bottom output shaft of the electric cylinder via bolts, and cylinders are mounted on both sides of the pressure plate via bolts, a movable plate is mounted on the output end of the cylinder via bolts, a receiving groove is provided on the bottom surface of the pressure plate, and a first spring is equidistantly welded at the top of the receiving groove, and a lifting plate is welded to the free end of the first spring.

[0008] Furthermore, a positioning groove is opened on the edge surface of the top of the base close to the vertical plate, and a second spring is welded in the positioning groove. A limiting plate is welded on the top of the second spring, and the top of the limiting plate is located outside the positioning groove.

[0009] Furthermore, the bottom surface of the movable plate is provided with rotation grooves at equal intervals, and a rotation ball is rotatably connected in the rotation groove, and one end of the rotation ball is located outside the rotation groove.

[0010] Furthermore, rubber strips are glued and connected to the outer edges of the bottom of the pressing plate.

[0011] Furthermore, the top of the lifting plate is located in the accommodating groove, and the bottom of the lifting plate is located outside the accommodating groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] By setting an electric cylinder, a pressing plate and a movable plate, the pressing plate and the movable plate can be lowered under the action of the electric cylinder, thereby pressing down the center position of the steel belt at the top of the base, and then the movable plate can be moved toward the end of the steel belt at the top of the base under the action of the cylinder, so that the end of the steel belt can be flattened by the movable plate. The flattening mechanism flattens the steel belt through two steps, first pressing down the center position of the steel belt, and then horizontally moving the movable plate from the center position of the steel belt to the end of the steel belt, thereby avoiding the situation where the end of the steel belt will be pressed into a fold by the pressing plate due to the large concave amplitude of the end of the steel belt when only the pressing plate is pressed down, so as to ensure the leveling quality.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 , 2 As shown, a leveling mechanism for a steel coil cross-cutting machine comprises a base 1, one end of the base 1 is welded with a vertical plate 6, one side of the vertical plate 6 is installed with an electric cylinder 8 through a fixing rod 7 and bolts, the bottom output shaft of the electric cylinder 8 is installed with a pressing plate 5 through bolts, and both sides of the pressing plate 5 are installed with a cylinder 4 through bolts, the output end of the cylinder 4 is installed with a moving plate 3 through bolts, the bottom surface of the pressing plate 5 is provided with a receiving groove 10, and the top of the receiving groove 10 is equidistantly welded with a first spring 11, and the free end of the first spring 11 is welded with a lifting plate 12, when the pressing plate 5 descends, the lifting plate 12 will first contact the steel plate, and during the contact process, the first spring 11 will retract, thereby causing the lifting plate 12 to rise, so that the lifting plate 12 and the pressing plate 5 press down the steel plate together, and when the thickness of the steel plate is small, the lifting plate 12 can contact it under the action of the first spring 11, at this time, the device presses down and level the steel plate through the lifting plate 12.

[0021] Among them, Figure 1 , 3 As shown, a positioning groove 15 is provided on the edge surface of the top of the base 1 close to the vertical plate 6, and a second spring 16 is welded in the positioning groove 15, and a limiting plate 2 is welded on the top of the second spring 16, and the top of the limiting plate 2 is located outside the positioning groove 15. When the steel plate passes through the base 1, the limiting plate 2 can be used as a reference to make one end of the steel plate contact the limiting plate 2, so that the steel plate can pass through the base 1 more regularly, and when the pressing plate 5 descends, it will exert a certain force on the limiting plate 2, so that the second spring 16 retracts, and then the limiting plate 2 completely enters the positioning groove 5, so as to avoid the positioning groove 5 affecting the leveling operation of the steel plate.

[0022] Among them, Figure 4 As shown, the bottom surface of the movable plate 3 is equidistantly provided with rotating grooves 13, and a rotating ball 14 is rotatably connected in the rotating groove 13. One end of the rotating ball 14 is located outside the rotating groove 13, and the rotating ball 14 can contact the steel plate. Therefore, when the movable plate 3 moves, it encounters less resistance, so it will not make a loud noise.

[0023] Among them, Figure 1 As shown, the outer edges of the bottom of the pressing plate 5 are glued with rubber strips 9, and the rubber pads 9 have good deformation ability and can fully contact with the steel plate.

[0024] Among them, Figure 2As shown, the top of the lifting plate 12 is located in the receiving groove 10, and the bottom of the lifting plate 12 is located outside the receiving groove 10. The receiving groove 10 can limit the lifting plate 12 to a certain extent to prevent it from tilting.

[0025] It should be noted that the utility model is a leveling mechanism for a steel coil cross-cutting machine. When working, personnel can fix the mechanism on the feed side of the cross-cutting machine. At this time, when the steel strip passes through the top of the base 1 and enters the cross-cutting machine, if the end of the steel strip is concave upward due to winding, the personnel can control the electric cylinder 8 to work so that its output end drives the pressure plate 5 to descend, thereby causing the lifting plate 12 to press down the steel strip. Subsequently, the personnel can control the air cylinder 4 to work so that the movable plate 3 is away from the pressure plate 5, thereby allowing the movable plate 3 to press down the concave end of the steel strip. After a certain period of time, the steel strip will be flattened. At this time, the personnel can control the electric cylinder 8 again to raise the pressure plate 5 and the movable plate 3, thereby allowing the flattened steel strip to enter the cross-cutting machine under the action of the conveying mechanism.
