Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of steel plate longitudinal and transverse shearing, and particularly relates to a steel coil pressing and separating device. BACKGROUND

[0002] The steel plate longitudinal and transverse shearing machine is a mechanical device for metal plate processing, which can cut metal coil plates in the longitudinal and transverse directions according to the actual needs of customers to provide material preparation for subsequent forming processes. It usually includes two functions of longitudinal shearing and transverse shearing. The longitudinal shearing is mainly used for cutting metal coil plates into strip materials of the required width, and the strip materials can be rewound for use in the next process, which is commonly used in the precision shearing of metal strips in the transformer and motor industries. The transverse shearing is used for shearing metal coil plates into flat plate materials of the required length and stacking, which is suitable for the sizing transverse shearing operation of various metal materials such as cold-rolled and hot-rolled carbon steel, silicon steel and stainless steel. The longitudinal and transverse shearing machine has the advantages of simple operation, good cutting quality and high material utilization rate. It is usually composed of unwinding, leveling, shearing, discharging and other devices, and is equipped with storage pits, traction and correction devices, roller transition slides and other online mechanisms to form a complete production line.

[0003] The unwinding is to open and separate the steel coil set on the unwinding machine to better straighten it into the subsequent leveling machine for flattening operation. During the separation of the steel coil, if the head of the steel coil is directly straightened to the leveling machine and fed by the pulling force of the leveling machine, since the initial state of the steel coil is curled, direct connection with the leveling machine can easily cause the leveling machine to work under overload and malfunction. In addition, the discharge state of the steel coil cannot be controlled during the material transmission, which further increases the uncertainty of the steel coil separation and may even cause safety accidents.

[0004] Therefore, there is an urgent need for a new technical solution to solve the above technical problems. UTILITY MODEL CONTENTS

[0030] The present application will be further described in detail below according to the drawings and embodiments. The described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] As Figure 1As shown in the figure, a steel coil pressing and separating device comprises a pressing arm support 1, outwardly extending pressing arms 2 symmetrically arranged on the pressing arm support 1, pressing arms 3 arranged below the pressing arms 2, one end of the two pressing arms 3 being hinged to the side edges of the pressing arm support 1, i.e. the pressing arm support 1 is symmetrically provided with pressing arm supports 6 on one side, the pressing arm supports 6 being hinged to the ends of the pressing arms 3, and the hinging mode can adopt pin shaft connection; the other end of the two pressing arms 3 is provided with a pressing and separating assembly 4.

[0032] A pressing arm driving assembly 7 is arranged between the pressing arms 2 and the pressing arms 3, and under the action of the pressing arm driving assembly 7, the two pressing arms 3 can rotate upward or downward in an arc shape with the hinging point of the pressing arm support 1 as the center of rotation.

[0033] The pressing and separating assembly 4 comprises a pressing roller 401 movably arranged between the two pressing arms 3, and a pressing and separating roller assembly 402 arranged at the head of the two pressing arms 3 and capable of ascending and descending relative to the pressing arms 3.

[0034] Working principle:

[0035] The pressing arm support 1 is installed in the adjacent position of the decoiler of the longitudinal and transverse shearing system, and the two pressing arms 2 are directed towards the separating surface of the steel coil, the pressing arms 3 are driven by the pressing arm driving assembly 7 to move downward in a clockwise direction, until the pressing roller 401 is in contact with the upper surface of the steel coil, and during the conveying process of the steel coil by the leveling machine, the pre-pressing and separating of the steel coil is realized, and the curling degree of the steel coil entering the leveling machine can be greatly reduced.

[0036] In this embodiment, after the steel coil is pressed and separated, it will enter the rear leveling machine through the space between the two pressing arms 2, and in order to support the steel coil after pressing and separating, a supporting beam is arranged on the pressing arm support.

[0037] As shown in the figure, Figure 2 and Figure 3 In this embodiment, the pressing arm driving assembly 7 comprises a pressing and separating oil cylinder 701 fixedly connected to the top of the pressing arm 2, the piston end of the pressing and separating oil cylinder 701 is connected with a pressing and separating oil cylinder joint 702, and the pressing and separating oil cylinder joint 702 is hinged to a pressing and separating oil cylinder support 703 arranged on the pressing arm 3.

[0038] During operation, the pressing and separating oil cylinder 701 is controlled by an external electric control system to drive the pressing arms 3 to ascend or descend, so that it can better adapt to steel coils of different outer diameters, thereby increasing the application range of the device to steel coils of different specifications.

[0039] As the optimization of the scheme, a synchronization shaft 5 is further arranged between the two pressing arms 3; since each pressing arm 3 in the embodiment is driven and controlled by an independent pressure distribution oil cylinder 701, the synchronization shaft 5 can ensure that the two pressing arms 3 work synchronously, thereby better acting on the steel coil.

[0040] As shown in Figure 2 and Figure 3 The pressure distribution roller assembly 402 in the embodiment comprises a pressure distribution sliding block 404 arranged in pairs, and the pressure distribution sliding block 404 is provided with a pressure distribution hanging foot 406 capable of clamping the pressure distribution roller 405.

[0041] The head of the pressing arm 3 is provided with a sliding block sliding groove 301 matched with the pressure distribution sliding block 404, and a moving oil cylinder is arranged at the head of the pressing arm 3, and the piston end of the moving oil cylinder is connected with a moving oil cylinder joint 407 arranged on the pressure distribution sliding block 404.

[0042] When it is necessary to further press the rear end of the steel coil acted on by the pressing roller 401 through the pressure distribution roller 405, the moving oil cylinder is controlled by an external electric control system to drive the pressure distribution sliding block 404 to drive the pressure distribution roller 405 to ascend and descend, thereby realizing better pressure distribution control of the steel coil.

[0043] It should be noted that the outer diameter of the pressing roller 401 in the embodiment is smaller than the outer diameter of the pressure distribution roller 405.

[0044] The pressure distribution hanging foot 406 comprises an open outward C-shaped groove 408.

[0045] Specifically, the pressure distribution roller 405 is movably sleeved with a pressure distribution roller shaft 409, both ends of the pressure distribution roller shaft 409 are clamped through the C-shaped groove 408 and locked through a pin shaft, so as to ensure that the pressure distribution roller shaft 409 is firmly connected in the C-shaped groove 408.

[0046] Through the structure, firm connection of the pressure distribution roller 405 can be realized, and the pressure distribution roller 405 can rotate freely relative to the pressure distribution roller shaft 409, especially when it acts on the steel coil, the pressure distribution roller 405 can also follow the movement of the steel coil under the action of the transmission force of the steel coil while applying pressure to the steel coil.

[0047] The pressing roller 401 in the embodiment has two connection modes relative to the pressing arm 3:

[0048] Mode 1: the pressing roller 401 is movably sleeved with a pressing roller shaft 403, and pressing roller shaft sleeve holes 302 capable of sleeving the end of the pressing roller shaft 403 are arranged on the two pressing arms 3.

[0049] The two ends of the pressing roller shaft 403 are respectively sleeved with the pressing roller shaft sleeve hole 302 to complete the fixation, and the pressing roller 401 can follow the transmission force of the steel coil when the pressing roller 401 acts on the steel coil, and can also apply pressure to the steel coil.

[0050] In mode 2, the pressing roller 401 is sleeved with the pressing roller shaft 403, and the two pressing arms 3 are respectively provided with the pressing roller shaft sleeve hole 302 which can sleeve the end of the pressing roller shaft 403, and the bearing is embedded between the pressing roller shaft 403 and the pressing roller shaft sleeve hole 302.

[0051] In this structure, the pressing roller 401 and the pressing roller shaft 403 are integrated, and the rotation is realized through the bearing.

[0052] As the optimization of the embodiment, the end of the pressing roller shaft 403 can extend out of the pressing roller shaft through hole 302 and be connected with the pressing roller driving device.

[0053] The embodiment can realize the rotation driving of the pressing roller 401 by adding the pressing roller driving device, and can further give the steel coil a certain transmission force, so that the work load of the rear end flattening machine is further reduced.

[0054] The pressing roller driving device comprises a sprocket (not marked in the drawing) sleeved with the extended part of the pressing roller shaft 403, and the sprocket is connected with the external sprocket motor through a chain.

[0055] The above description is only for the implementation mode of the utility model, and is not used for limiting the utility model, and any modification, equivalent replacement, improvement and the like made by the person skilled in the art within the spirit and principle of the utility model should be included in the protection scope of the utility model.
