Description

Three-roller type thin plate uncoiling and head-peeling mechanism device

Technical Field

The invention relates to a steel coil processing device, in particular to a three-roller type thin plate uncoiling and head-peeling mechanism device.

Background

In the hot rolling production line of iron and steel enterprise, the general unwinding mechanism who adopts a straight-head sword form to the operation of opening a book of coil of strip is when leveling, cutting edge, sample production to some in process of products in the hot rolling product of longitudinal observation, and the mode of its opening a book is for controlling a straight-head sword through the operation personnel and is pressing close to the surface of coil of strip with it directly, and then rotatory coil of strip will be carried the head to the tool bit department of straight-head sword to the operation is opened to belted steel head card formula mode. If the thin plate (1.2MM-2.6MM) and the thick plate (more than 7 MM) are encountered, the problems of over-thin and over-thick thickness are solved, and the problems that the straight-end cutter and the rotating steel coil need to be repeatedly operated for many times are easily caused during uncoiling:

1. the straight-end cutter scratches and scratches the surface of the steel coil,

2. if the steel coil is not in place in the rotating position, the straight-end cutter can be damaged by collision, and the normal production is influenced.

The existing uncoiling has the following defects:

(1) for thinner and thicker strip decoiling is not easy.

(2) The quality problem of the surface of the strip steel is easy to generate.

(3) The adaptability is not strong.

(4) The efficiency of the work is comparatively low.

In the existing working condition, the above-mentioned uncoiling technology obviously cannot meet the field operation requirements, so that an uncoiling structure capable of making up the above-mentioned defects is needed.

Detailed Description

The technical scheme of the invention is further explained by combining the drawings and the embodiment.

Referring to fig. 1, the invention discloses a three-roller type thin plate uncoiling and head-peeling mechanism device, which comprises main structural components, namely an uncoiling platform 1, a swing arm 2, a connecting pin shaft 3, an uncoiling arm 4, an uncoiling ground roller front platform 5, a ground roller 6, a front pressing roller 7, a pressing roller 8, a pressing plate 9, a rear pressing roller 10, an uncoiling knife 11, an angle adjusting bolt 12 and the like. The structural features and connection relationships of the above-described respective components will be described in detail below.

Referring to fig. 1, one end of the uncoiling platform 1 is provided with a ground roller 6, and the connection part of the ground roller 6 and the uncoiling platform 1 is an uncoiling ground roller front platform 5. The upper surface of the uncoiling platform 1 is provided with a pressing roll, the pressing roll is connected with an uncoiling arm 4, the uncoiling arm 4 is connected with a swing arm 2, the swing arm 2 drives the uncoiling arm 4 to rotate, the swing arm 2 and the uncoiling arm 4 are connected through a connecting pin shaft 3, and the uncoiling arm 4 drives the pressing roll to open or close.

Specifically, as shown in fig. 1, the pressure rollers include a front pressure roller 7, a proximity roller 8, a rear pressure roller 10, and a surface proximity plate 9. Preceding pinch roller 7, press close to roller 8 and back pinch roller 10 parallel arrangement in proper order, the board 9 is pressed close to in the surface with preceding pinch roller 7, press close to roller 8 and back pinch roller 10 and link into an integrated entity, back pinch roller 10 is connected and is opened a book arm 4.

The main function of the front pressing roller 7 and the rear pressing roller 10 is to drive the steel coil to rotate forward and backward under the action of the surfaces of the pressed steel coils of the two rollers when the steel coil is uncoiled, so that the strip steel is prevented from being loosened when being uncoiled and coiled. The function of the proximity roller 8 is to ensure that the steel coil is prevented from scratching and scratching the surface of the strip steel by the uncoiling knife 11 during operation, and meanwhile, the proximity roller is matched with the three rollers of the front and rear pressing rollers 10 to ensure that the head of the strip steel can smoothly enter the shearing edge. The action of the surface closing plate 9 plays a role in rotating the head of the steel coil by the front pressing roller 7 and the rear pressing roller 10 when the swing arm 2 is opened to be close to the surface of the steel coil, and simultaneously controlling the scratch and scratch generated after the swing arm is too close to the surface of the steel coil.

The uncoiling knife 11 is arranged in front of the pressing roller, is designed in an isosceles triangle shape, is provided with equivalent built-in bolts on the surface, and is fixedly connected with a frame of the uncoiling platform 1 through a fixing plate. The uncoiling knife 11 comprises an angle adjusting bolt 12, and the angle of the uncoiling knife 11 is adjusted by the angle adjusting bolt through adjusting the opening degree, and is plus or minus 15 degrees.

As shown in fig. 1-3, when the operation personnel is carrying out the operation of opening a book to the relevant coil of strip, hang to the ground roller 6 of opening a book the structure by the operation personnel to open a book the coil of strip by the operation personnel, will open a book the position through the swing arm 2 and open certain aperture, then rotate the coil of strip head to anterior position, press close to board 9 through swing arm 2 after the pendulum-upward pendulum and be close to the coil of strip surface, open the head position that coil of strip sword 11 contacted to, then rotatory coil of strip will open coil of strip sword 11 and insert the head position of coil of strip, treat the complete insertion back, close swing arm 2 to the position on opening a book platform 1, press the coil of strip front portion to press close to through pressing close to roller 8, and through preceding pinch roller 7, the effect of back pinch roller.

After the crop finishes, the operation personnel move back the head to the position of preceding compressing roller 7 through the rotation of coil of strip, open swing arm 2 for belted steel breaks away from and presses close to roller 8 and back compressing roller 10, and after taking off from 11 positions of book sword at last, will open a book the structure and close to the starting position through swing arm 2.

The angle of the uncoiling knife 11 can be adjusted through an adjusting bolt, if the opening degree is increased at any time when the uncoiling knife meets a thick plate, the opening degree is decreased when the plate is thin, and the adjusting angle is positive or negative 15 degrees.

It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
