Description

Technical Field

[0001] The utility model relates to the technical field of metal coil processing equipment, in particular to a material guiding and pre-calibration device. Background Art

[0002] During the metal coil processing, such as transverse shearing (cutting continuous metal sheets into metal sheets) or strip processing, the metal coil needs to be placed on the uncoiler, and the head of the metal coil is pulled into the leveling machine. The uncoiler performs the coil uncoiling operation, and the leveling machine performs the leveling pre-calibration.

[0003] Among them, the Chinese utility model patent with patent number: ZL202223225602.6 and patent name: A coil head finding assembly for an uncoiler, which specifically discloses the following technical solutions, specifically: A coil head finding assembly for an uncoiler, including an uncoiler frame and a leveling frame, a rocker arm is rotatably installed on the uncoiler frame, a mounting plate is fixed to the end of the rocker arm by screws, a motor is fixedly installed on one side of the mounting plate, the output end of the motor is connected to a rotating shaft through a coupling, a pusher wheel is fixedly sleeved on the outside of the rotating shaft, and the rocker arm, the mounting plate, the motor, the rotating shaft and the pusher wheel together constitute an uncoiler pushing assembly; a lower pressure plate is rotatably installed on one side of the leveling frame, the lower pressure plate is driven by a cylinder, a sliding plate driven by a cylinder is slidably installed in the movable groove of the lower pressure plate, the sliding plate performs telescopic movement relative to the lower pressure plate, a dial block is fixed to the top of one end of the sliding plate by screws, the dial block is a triangular plate structure, the lower pressure plate, the sliding plate, the dial block and the corresponding cylinder together constitute a head finding and guiding assembly.

[0004] When the coil head finding assembly of the above-mentioned uncoiler is working, the coil is rotated and sleeved on the uncoiler frame. When the coil needs to be introduced into the leveling machine, the rocker arm rotates under the action of the driving source and the pushing wheel contacts the outer peripheral surface of the coil. The lower pressure plate rotates under the drive of the cylinder and the lower pressure plate brings the head block toward the coil. At the same time, the sliding plate extends out under the drive of the cylinder and makes the head block contact with the outside of the coil. Under the action of the pushing wheel, the coil rotates slowly. When the head of the coil contacts the head block, it is pushed away by the head block, thereby finding the head of the coil. When the head is found, the head of the coil is guided into the leveling machine by the head finding and guiding assembly.

[0005] It should be pointed out that the above-mentioned uncoiler coil head finding assembly has the following defects. Specifically, since the head of the metal coil is easily warped, in order to ensure that the head of the metal coil can smoothly enter the leveling machine, the warped head of the metal coil needs to be knocked flat. However, the uncoiler coil head finding assembly lacks a corresponding knocking structure to knock the warped head of the metal coil flat. Therefore, for the metal coil with a warped head, it is still necessary to rely on manpower to carry out the knocking operation, and the degree of automation is not high. Utility Model Content

Specific embodiments

[0030] The following will describe the present utility model in conjunction with specific embodiments.

[0031] Embodiment 1, as Figure 1 shown, a feeding and pre-aligning device includes a leveling machine 1 and an uncoiler 2 located at the front side of the leveling machine 1. The leveling machine 1 includes a frame 11 and a plurality of pre-leveling and pre-aligning roll groups 12 respectively installed on the frame 11 and arranged at intervals from front to back.

[0032] Among them, as Figure 1 shown, an uncoiling and pushing component 3 and a head-finding and feeding component 4 are installed between the leveling machine 1 and the uncoiler 2. The uncoiling and pushing component 3 includes a movable swing arm 31 pivotally hinged to the frame 11 through a pivot. The movable swing arm 31 performs a vertical rotation action under the driving action of the swing arm driving oil cylinder 32. A pushing roll 33 is rotatably installed at the front end of the movable swing arm 31, and a pushing driving motor 34 for driving the pushing roll 33 to rotate is installed at the front end of the movable swing arm 31; it should be noted that the power output shaft of the pushing driving motor 34 can be drivingly connected to the pushing roll 33 through a chain transmission mechanism.

[0033] When the uncoiling and pushing component 3 in Embodiment 1 performs the uncoiling operation of the metal coil, the metal coil is placed on the uncoiler 2. The swing arm driving oil cylinder 32 drives the movable swing arm 31 to rotate downward so that the pushing roll 33 presses against the outer peripheral surface of the metal coil. The pushing driving motor 34 drives the pushing roll 33 to rotate, and the rotating pushing roll 33 drives the metal coil to rotate and perform the uncoiling action of the metal coil.

[0034] Furthermore, as Figures 1 to 3As shown, the head-finding and material-guiding assembly 4 includes a movable material-guiding plate 41 hinged on the frame 11 through a pivot, and the movable material-guiding plate 41 performs a vertical rotation movement under the driving action of a material-guiding plate driving cylinder 42; the movable material-guiding plate 41 is telescopically and slidably installed with a telescopic shovel plate 43, and the telescopic shovel plate 43 performs a telescopic movement under the driving action of a telescopic driving cylinder 44.

[0035] During the process of the head-finding and material-leading operation of the head-finding and material-leading assembly 4 of the first embodiment, the material-leading plate driving cylinder 42 drives the movable material-leading plate 41 to rotate vertically, and the telescopic driving cylinder 44 drives the telescopic shovel plate 43 to extend from the movable material-leading plate 41 and makes the front end of the telescopic shovel plate 43 contact and abut against the metal coil. When the head of the metal coil rotates to the position of the telescopic shovel plate 43, the telescopic shovel plate 43 separates the head of the metal coil. At this time, the movable material-leading plate 41 and the telescopic shovel plate 43 cooperate and guide the protruding part of the metal coil to the leveling machine 1.

[0037] When the head of the metal coil is tilted, the material-beating driving cylinder 51 is started, and the material-beating driving cylinder 51 drives the movable material-beating plate 52 to move up and down and perform a knocking action. When the movable material-beating plate 52 knocks the head of the metal coil, the movable material guide plate 41 or the telescopic shovel plate 43 supports the head of the metal coil from the lower position, and enables the movable material-beating plate 52 to knock the tilted head of the metal coil flat, so as to ensure that the head of the metal coil can smoothly enter the leveling pre-calibration roller group 12 of the leveling machine 1.

[0038] It should be emphasized that the material guiding and pre-calibration device of the first embodiment can knock down the raised head of the metal coil through the head knocking mechanism 5, and has a high degree of automation.

[0039] In summary, it can be seen that, through the above structural design, the material guiding and pre-calibration device of the first embodiment has the advantages of novel structural design and high degree of automation, and can effectively realize the function of flattening the raised head of the metal coil.

[0040] Embodiment 2, as Figure 1 As shown, the difference between the second embodiment and the first embodiment is that the movable swing arm 31 is fastened with a guide sleeve 53 , the movable punching plate 52 is fastened with a guide column 54 corresponding to the guide sleeve 53 , and the guide column 54 passes through the center hole of the guide sleeve 53 .

[0041] In Embodiment 2, by means of the guiding pair structure composed of the guide sleeve 53 and the guide pillar 54, the movable ejector plate 52 can be effectively guaranteed to move up and down smoothly.
