[0003] To improve the flattening effect of the end face of the steel coil, a flattening device for hitting the end face of the steel coil has been developed.The steel coil flattening device, as described in Chinese patent application No.201320065056.6, generally includes two push plates that can move relative to each other;when in operation, the two push plates are on the two end faces of the steel coil and move relative to each other to hit the end face of the steel coil.The existing steel coil flattening device moves the push plate by a large distance to hit the end face of the steel coil from the side of the steel coil.The hitting of the push plate can arrange the end face of the steel coil to a certain extent, but the hitting frequency is low under the condition of large hitting, the vibration effect of the push plate on the steel coil is poor, the steel coil is basically arranged by the pushing force of the push plate during the hitting process, the arrangement of the steel coil is difficult, and the flattening effect of the end face of the steel coil is poor;furthermore, the disc surface of the existing push plate is fixed, and the push plate cannot contact the uneven end face of the steel coil, but only partially contact the uneven end face of the steel coil, the force acting on the uneven end face of the steel coil is small and the pressure is large, the acting force of the push plate is difficult to accurately control and utilize, and the end face of the steel coil is also prone to damage. SUMMARY

[0004] The purpose of the present application is to provide a steel coil flattening device.

[0005] The technical scheme for achieving the object of the present application is: a steel coil flattening device, comprising a flattening mechanism, the flattening mechanism comprising a moving seat and a pushing disc, the moving seat being in transmission connection with a driving mechanism and being driven by the driving mechanism to be movable, an installation shaft being axially through a shaft sleeve and being axially movable relative to the shaft sleeve, a first end of the installation shaft being in abutting contact with one end of a compression spring, the other end of the compression spring being in abutting contact with the moving seat, the shaft sleeve being parallel to the moving path of the moving seat, the shaft sleeve being fixedly installed on the moving seat, a second end of the installation shaft being connected with the pushing disc through a ball joint, the ball joint comprising a joint ball and a joint groove, one of the joint ball and the joint groove being arranged on the second end of the installation shaft and the other being arranged on the back surface of the pushing disc, the joint ball being rotatably installed in the joint groove, and a vibrating mechanism being further arranged on the moving seat and being capable of vibrating the back surface of the pushing disc.

[0006] Further, the installation shaft is movably installed with the shaft sleeve through a limiting structure, the limiting structure comprising a limiting hole and a limiting pin, the limiting pin being inserted into the limiting hole, the length of the limiting hole along the axial direction of the installation shaft being greater than the diameter of the limiting pin, one of the limiting hole and the limiting pin being arranged on the installation shaft and the other being arranged on the shaft sleeve. Under the premise that the length of the limiting hole along the axial direction of the installation shaft is greater than the diameter of the limiting pin, after the limiting pin is inserted into the limiting hole, the limiting pin is limited by the limiting hole to form a limiting structure. Under the limiting structure of the limiting pin and the limiting hole, one of the limiting hole and the limiting pin is arranged on the installation shaft and is integrated with the installation shaft, and the other is arranged on the shaft sleeve and is integrated with the shaft sleeve, and the installation shaft and the shaft sleeve also form a limiting relationship, which ensures that the installation shaft can move axially in the shaft sleeve and the installation shaft inserted into the shaft sleeve will not come out of the shaft sleeve and form a stable installation relationship with the shaft sleeve. When the length of the shaft sleeve is relatively long, the installation shaft inserted into the shaft sleeve can form a stable installation relationship with the shaft sleeve without the limiting structure and will not come out of the shaft sleeve. Preferably, the installation shaft is movably installed with the shaft sleeve through the limiting structure, and the setting of the limiting structure can make the installation relationship between the installation shaft and the shaft sleeve more reliable. In the limiting structure, the limiting hole can be arranged on the installation shaft and the limiting pin can be arranged on the shaft sleeve, or the limiting hole can be arranged on the shaft sleeve and the limiting pin can be arranged on the installation shaft.

[0007] Further, the limiting hole is parallel to the installation shaft. This setting is simple and effective.

[0008] Further, the other end of the compression spring is sleeved on the first end of the mounting shaft. The compression spring sleeved on the mounting shaft can limit the mounting shaft, and the compression spring is not easy to be damaged by bending when deforming under the limiting effect of the mounting shaft.

[0009] Further, the moving seat comprises a moving seat body and a limiting sleeve, the limiting sleeve is parallel to the shaft sleeve, one end of the shaft sleeve extends into the limiting sleeve and is fixedly installed with the limiting sleeve, the limiting sleeve is fixedly installed on the moving seat body, and the compression spring is located in the limiting sleeve. Under this structure, on the one hand, when the fixed installation structure of the shaft sleeve and the moving seat is realized, the installation structure of the shaft sleeve installed in the limiting sleeve is simple and easy to realize, for example, after the one end of the shaft sleeve extends into the limiting sleeve, a fastening ring is driven between the shaft sleeve and the limiting sleeve, and the fixed installation of the shaft sleeve and the moving seat can be realized; on the other hand, after the compression spring is located in the limiting sleeve, the limiting sleeve can limit the compression spring, and the compression spring is not easy to be damaged by bending when deforming under the limiting effect of the limiting sleeve.

[0010] Further, the joint ball is arranged on the mounting shaft, and the joint groove is arranged on the back surface of the push disc; the push disc comprises a push disc body and a lock block, the lock block is locked on the back surface of the push disc body through a bolt, the back surface of the push disc body is provided with a hemispherical groove, the lock block is provided with a through hole with a spherical wall, and the hemispherical groove and the through hole jointly form the joint groove. During installation, the lock block is first sleeved on the mounting shaft, then the joint ball on the mounting shaft is arranged in the hemispherical groove of the push disc body, and then the lock block is locked on the back surface of the push disc body through the bolt, so that the joint ball is finally rotatably locked in the joint groove, and the push disc is movably installed on the mounting shaft. The above structure can facilitate the formation of the joint groove and the installation of the push disc and the mounting shaft.

[0011] Further, the vibration mechanism is an air vibrator.

[0012] Further, the number of the vibration mechanisms is several, and the several vibration mechanisms are uniformly distributed along the circumference of the mounting shaft. When the several vibration mechanisms around the mounting shaft vibrate the inclined push disc, the distances from the vibration mechanisms to the push disc are different, and the vibration mechanisms far from the push disc have small vibration strength, and even do not vibrate the push disc; the vibration mechanisms close to the push disc have large vibration strength, and make the push disc and the steel coil end surface inclined to the side far from the vibration mechanisms to be flat. In this way, no matter which side is inclined to the vibration mechanism, the side is vibrated, and the effective vibration can be realized.

[0013] Further, the number of the flattening mechanisms is two, and the two flattening mechanisms are horizontally arranged, and the moving paths of the two flattening mechanisms are in the same horizontal direction. The number of the flattening mechanisms can be one or two. When the number of the flattening mechanisms is one, one end surface of the steel coil is pressed, and then the single flattening mechanism flattens the one end surface of the steel coil, and then the other end surface can be flattened. When the number of the flattening mechanisms is two, the two flattening mechanisms can simultaneously flatten the two end surfaces of the steel coil from the two sides of the steel coil. Compared with the single flattening mechanism, the two flattening mechanisms simultaneously flatten the two end surfaces of the steel coil from the two sides of the steel coil, and the efficiency is higher and the effect is better. In addition, the flattening mechanism can be vertically arranged or horizontally arranged. When the flattening mechanism is vertically arranged, the steel coil is also vertically arranged, and the flattening mechanism moves in the vertical direction to flatten the end surface of the steel coil; when the flattening mechanism is horizontally arranged, the steel coil is also horizontally arranged, and the flattening mechanism moves in the horizontal direction to flatten the end surface of the steel coil. Compared with the vertical arrangement, when the flattening mechanism is horizontally arranged, the steel coil is more convenient to put and take, and is not affected by gravity, and the force applied by the two flattening mechanisms to the two sides of the steel coil is more balanced.

[0014] Further, the flattening mechanism can be movably hoisted on a hoisting beam. Compared with the floor-mounted frame, the hoisting beam is hoisted, and the occupation area is smaller.

[0015] Further, the driving mechanism is a pneumatic cylinder.

[0016] The steel coil flattening device, by setting the vibration mechanism on the moving seat, the push disc top pressure steel coil end face, can be by the vibration mechanism high frequency vibration to beat to the steel coil for flattening. Compared with the traditional push disc back and forth movement, beat the steel coil, the structure of the steel coil flattening device, on the one hand, the vibration mechanism body small flexible, and as a special vibration structure, the vibration frequency of the vibration mechanism is higher than the traditional push disc back and forth movement frequency, the high frequency vibration of the vibration mechanism can make the steel coil end face quickly get flat; on the other hand, the direct hitting object of the vibration mechanism in the vibration process is the push disc, not the steel coil, the force of the vibration mechanism is transferred to the steel coil by the push disc, because the action surface of the push disc and the steel coil is large, when the push disc transfers the force of the vibration mechanism to the steel coil, the pressure on the steel coil is small, the surface of the steel coil is not easy to deform and damage due to excessive pressure, that is, the steel coil can be better protected to prevent injury during flattening.

[0017] The steel coil flattening device, the push disc is installed on the mounting shaft through the ball joint comprising the joint ball and the joint groove, and the disc surface of the push disc can be flexibly changed. When the disc surface of the push disc top pressure steel coil end face, under the action of top pressure, no matter how the steel coil end face is inclined due to unevenness, the push disc can flexibly rotate to adapt to the steel coil end face, and always top pressure the steel coil end face in the form of near surface contact. Compared with the structure of the traditional push disc with fixed and unadjustable disc surface, the adaptability of the push disc is better, which can automatically adapt to the steel coil end face, no matter how the steel coil end face is inclined, the action surface of the push disc on the steel coil is always larger, and the pressure on the steel coil can be always smaller, without deformation and damage.

[0018] In addition, the steel coil flattening device, the push disc is installed on the mounting shaft, the mounting shaft is arranged in the shaft sleeve, and can move relative to the shaft sleeve. Under the structure of relative movement, the shaft sleeve is in top contact with the compression spring. When the push disc top pressure steel coil to flatten the steel coil end face, on the one hand, the force of the mounting shaft on it can be converted into its deformation, so that the push disc can top pressure the steel coil in the moment, and the top pressure action is slow and the impact force is small, which is better for protecting the push disc and the steel coil; on the other hand, the push disc can always have the force of pushing the steel coil, and always top pressure the steel coil, especially as the flattening operation proceeds, the inclination of the steel coil end face changes gradually, the force of the compression spring can make the push disc adapt to the change of the inclination of the steel coil end face, so that the push disc can always top pressure the steel coil no matter how the steel coil end face changes, and the operation is smooth, avoiding the situation that the steel coil end face cannot be top pressure in the later stage of operation, so as to avoid the situation that the operation cannot be carried out.

[0019] The present invention relates to a steel coil leveling device. After the pusher is mounted on the mounting shaft that contacts the compression spring via the ball joint, the high-frequency vibration of the vibration mechanism can perform efficient leveling of the steel coil, resulting in a good flatness of the steel coil end face. Furthermore, the pusher and the steel coil are well protected from damage during the entire leveling process. Attached Figure Description

The bushing 3 is parallel to the movement path of the movable base 1 and is fixedly mounted on the movable base 1. The second end 42 of the mounting shaft 4 is connected to the push plate 2 via a ball joint 6. The ball joint 6 includes a joint ball 61 and a joint groove 62. One of the joint ball 61 and the joint groove 62 is located on the second end of the mounting shaft 4, and the other is located on the back of the push plate 2.

[0027] The steel coil flattening device, when working, the driving mechanism 101 drives, drives the flattening mechanism 10 to move to the steel coil 100, makes the push disc 2 of the flattening mechanism 10 close to and press the end face of the steel coil 100, under the influence of the pressing force, the joint ball 61 and the joint groove 62 in the ball joint 6 connected with the push disc 2 and the mounting shaft 4 relatively rotate, the push disc 2 after rotation is parallel to the end face of the steel coil and is attached, at the same time, the pressing force is transmitted to the compression spring 5 through the mounting shaft 4, and part of the pressing force is converted into the deformation of the compression spring 5, and conversely, the deformed compression spring 5 provides extrusion force outward for the push disc 2, so that the push disc 2 always presses the end face of the steel coil 100. Then, the vibration mechanism 7 vibrates, and the push disc 2 and the end face of the steel coil are high-frequency hit, so that the end face of the steel coil is flattened under the high-frequency vibration.

[0028] The steel coil flattening device, in the process that the vibration mechanism 7 vibrates and high-frequency hits the push disc 2 and the end face of the steel coil, with the continuous improvement of the flattening effect, the position of the push disc 2 and the end face of the steel coil will change, no matter how the position of the push disc 2 and the end face of the steel coil changes, under the action of the compression spring 5, the push disc 2 always presses the end face of the steel coil 100.

When the disc surface of the push disc 2 top flat steel coil end face, under the top pressure force, no matter how the steel coil end face is inclined due to unevenness, the push disc 2 can flexibly rotate to adapt to the steel coil end face, and always top pressure the steel coil end face in the way of near surface contact. Compared with the structure of the traditional push disc whose disc surface is fixed and cannot be adjusted, the adaptability of the push disc 2 of the present application is better, which can automatically adapt to the steel coil end face, no matter how the steel coil end face is inclined, the action surface of the push disc 2 on the steel coil is always larger, and the pressure on the steel coil can always be smaller, so that the steel coil will not deform and damage.

[0031] In addition, the steel coil flattening device of the present application, the push disc 2 is installed on the mounting shaft 4, the mounting shaft 4 is arranged in the shaft sleeve 3, and can move relative to the shaft sleeve 3, under the structure of relative movement, the shaft sleeve 3 is in contact with the compression spring 5, the existence of the compression spring 5 can convert the force of the mounting shaft 4 to its own deformation when the push disc 2 top pressure the steel coil and flatten the steel coil end face, so that the push disc 2 can play a buffering role in the instant of top pressure the steel coil, the top pressure action is slow, the impact force is small, and the protection effect of the push disc 2 and the steel coil is better; On the other hand, the push disc 2 can always have a pushing force, so that the push disc 2 always has a pushing force to the steel coil, and always top pressure the steel coil, especially as the flattening operation proceeds, the inclination of the steel coil end face changes gradually, the force of the compression spring 5 can make the push disc 2 adapt to the change of the inclination of the steel coil end face, no matter how the steel coil end face changes, the push disc 2 can always top pressure the steel coil and work smoothly, avoiding the situation that the steel coil end face cannot be top pressure and work in the later stage of operation due to the change of the inclination of the steel coil end face.

[0032] The steel coil leveling device of the present invention, wherein the push plate 2 is mounted on the mounting shaft 4 that contacts the compression spring 5 via the ball joint 6, and is vibrated at high frequency by the vibration mechanism 7, can perform efficient leveling of the steel coil, with good flatness of the end face of the steel coil, and can also protect the push plate 2 and the steel coil from damage during the entire leveling process.
