Description

Technical Field

[0001] The utility model relates to the technical field of steel material processing equipment, in particular to a flat roll rounding device. Background Art

[0002] In the thin slab continuous casting and rolling production line, due to the combined influence of certain steel specifications, curling temperature and thickness, flat coils will appear during the transfer process from the coiler to the walking beam due to the fixed position. If the flat coils are directly scrapped, huge economic losses will occur.

[0003] In the prior art, the coil shape can be repaired by re-rolling on a flattening machine.

[0032] Please refer to the attached Figure 1-3 In one embodiment of the utility model, a flat roll extrusion device is provided, including an extrusion mechanism, a driving mechanism and a bottom plate, and the extrusion mechanism is arranged on the bottom plate. First of all, it should be noted that the longitudinal direction in the present application refers to the length direction of the bottom plate, and the transverse direction refers to the width direction of the bottom plate; it is different from the prior art that the roll shape can be repaired by re-rolling on a flattening machine, but before the flattening and curling mandrel is placed, the inner circle that has become an ellipse must be cut off for several circles until the minor diameter of the ellipse is slightly larger than the diameter of the curling mandrel before it can be re-rolled and repaired on a flattening machine. The processing of cutting off the inner circle will convert and produce a large amount of waste materials, resulting in a waste of steel and occupying space; if the roll shape is not processed and the flat roll is directly rotated on the curling mandrel, it is also a very poor working condition, which will seriously endanger the service life of the curling machine and the mandrel. The present application solves the above-mentioned defects in the prior art by providing a flat roll extrusion device, as follows:

[0033] The extrusion mechanism 10 includes two extrusion units arranged opposite to each other in the longitudinal direction, each of the extrusion units includes an extrusion portion 110 and a mounting portion 120, wherein the mounting portion 120 is movably connected to the bottom plate 30 in the longitudinal direction, and an adjustment slot 121 extending vertically is provided on the mounting portion 120, and the extrusion portion 110 is movably connected to the adjustment slot 121 in the vertical direction, and an extrusion space for placing the flat roll 50 is formed between the two extrusion portions 110; the driving end of the driving mechanism 20 is connected to the extrusion portion 110 to drive the two extrusion portions 110 to move toward / inversely in the longitudinal direction.

[0034] Specifically, the flat roll 50 rounding device in the present application includes an extrusion mechanism 10, a driving mechanism 20 and a base plate 30, wherein the base plate 30 is used to bear the weight and for installing the extrusion mechanism 10, so that the extrusion mechanism 10 is arranged on the base plate 30; the extrusion mechanism 10 is used to extrude the elliptical flat roll 50 into a round shape, and under the drive of the driving mechanism 20, the extrusion effect is achieved to repair the elliptical roll shape, thereby eliminating the need to cut the inner circle of the elliptical flat roll 50.

[0035] The extrusion mechanism 10 includes two extrusion units arranged opposite to each other in the longitudinal direction, and the purpose of extrusion is achieved under the mutual extrusion of the two extrusion units. Each of the extrusion units includes an extrusion portion 110 and a mounting portion 120. The mounting portion 120 is used for mounting the extrusion portion 110, and is movably connected to the bottom plate 30 in the longitudinal direction to facilitate movement during extrusion or after extrusion. The spacing between the two mounting portions 120 can also be adjusted to improve applicability; the extrusion portion 110 is used to The flat roll 50 performs extrusion work to achieve the purpose of extruding a circle. Preferably, an adjustment groove 121 extending vertically is provided on the mounting portion 120, and the adjustment groove 121 is used for the installation of the extrusion portion 110, and the extrusion portion 110 is movably connected to the adjustment groove 121 along the vertical direction, so that the height of the extrusion portion 110 can be adjusted. When the contact position between the extrusion portion 110 and the flat roll 50 is adjusted to the plane where the major axis of the ellipse of the flat roll 50 is located, it is the best pressure position for extruding a circle, and the extrusion effect is best at this time.

[0036] Among them, the driving mechanism 20 is used to drive the extrusion part 110 to connect, and its driving end is linked to the two extrusion parts 110. In this way, when the flat roll 50 is placed in the extrusion space and the extrusion part 110 is adjusted to the best position for contact with the flat roll 50, the driving mechanism 20 is controlled to control the two extrusion parts 110 to move towards each other. At this time, the two extrusion parts 110 squeeze toward the flat roll 50 located between the two and start the rounding work; when the rounding is completed, the driving mechanism 20 is controlled to control the two extrusion parts 110 to move in the opposite direction to facilitate the lifting of the steel roll.

[0037] As a preferred embodiment of the present invention, the extrusion portion 110 includes a mounting plate 111 and an extrusion disc 112 , the extrusion disc 112 is fixed on the mounting plate 111 , and the mounting plate 111 is movably connected to the adjustment slot 121 along the vertical direction.

[0038] It should be noted that the extrusion disk 112 is used to contact the flat roll 50 and extrude the flat roll 50 under the drive of the driving mechanism 20. Since the flat roll 50 is elliptical, in order to facilitate placement, in a preferred embodiment, the extrusion disk 112 is in an arc shape with its opening facing the flat roll 50, so that the flat roll 50 can be correspondingly and snugly arranged in the arc surface of the extrusion disk 112; and the mounting plate 111 is used for the installation of the extrusion disk 112, and the mounting plate 111 is movably connected to the adjustment groove 121 along the vertical direction to facilitate the up and down adjustment of the height position, so that the arc center horizontal plane of the extrusion disk 112 is adjusted to coincide with the horizontal plane where the elliptical major axis of the flat roll 50 is located, which is the optimal extrusion position.

[0039] Furthermore, considering that the extrusion disk 112 is in an arc shape, in order to facilitate the installation of the extrusion disk 112, the side of the mounting plate 111 close to the flat roll 50 can be recessed inward to form a curved surface, so that the back side of the extrusion disk 112 can be fitted in the recessed curved surface of the mounting plate 111, and the installation is more stable.

[0040] As a preferred embodiment of the present invention, the mounting portion 120 includes two support brackets 122 that are oppositely arranged in the transverse direction, each of the support brackets 122 is provided with the adjustment slot 121, and the support brackets 122 are movably connected to the base plate 30 in the longitudinal direction.

[0041] It should be noted that the support bracket 122 has a sufficient height and the adjustment groove 121 can be set close to the top, so that the extrusion part 110 can be supported to a sufficient height position when installed, and the adjustment groove 121 must be opened in each of the support brackets 122 to ensure synchronization of both ends during height adjustment.

[0042] As a preferred embodiment of the utility model, the driving mechanism 20 includes a connecting plate 210 and two driving units 220 arranged opposite to each other in the transverse direction, each of the driving units 220 includes a driving component 221 and a double-headed screw rod 222, wherein each of the mounting plates 111 is provided with an internal threaded hole, and the two ends of the double-headed screw rod 222 are respectively connected to the internal threaded holes of the two mounting plates 111 and extend outwardly, the driving component 221 is installed and connected to the connecting plate 210, and the driving end of the driving component 221 extends out of the connecting plate 210, and the driving end of the driving component 221 is fixedly connected to one end of the double-headed screw rod 222.

[0043] It is worth noting that the connecting plate 210 is used for installing the driving unit 220. Each of the driving units 220 includes a driving assembly 221 and a double-ended screw 222. The double-ended screw 222 can realize synchronous linkage of the two extrusion parts 110. Usually, the external threads at both ends of the double-ended screw 222 are one positive thread and the other negative thread. In this way, by rotating the double-ended screw 222, the mounting plates 111 respectively connected at both ends can move in the opposite direction. Therefore, in order to facilitate the connection, an internal threaded hole is opened on each of the mounting plates 111 so that the two ends of the double-ended screw 222 can be connected to each other. The ends are respectively connected to the internal threaded holes of the two mounting plates 111 and extended outwardly, so as to be fixedly connected with the driving end of the driving component 221 extending out of the connecting plate 210; it is worth mentioning that when the connecting plate 210 is fixed to the external frame, the driving component 221 fixed on the connecting plate 210 drives the double-headed screw rod 222 to rotate. Since the mounting plate 111 is fixed, the double-headed screw rod 222 rotates itself, causing the mounting plates 111 at both ends (under thread rotation) to slide longitudinally following the support bracket 122.

[0044] The driving assembly 221 can be used in combination with a hydraulic motor and a reducer to provide torque for the double-ended screw 222 .

[0045] As a preferred embodiment of the utility model, the extrusion part 110 also includes a hydraulic cylinder 113, and both ends of the mounting plate 111 are longitudinally protruding outward to form a protrusion 114, wherein the hydraulic cylinder 113 is fixed in the adjustment groove 121, and the top end of the hydraulic cylinder 113 is connected to the protrusion 114.

[0046] It is worth noting that the hydraulic cylinder 113 is used to adjust the height of the mounting plate 111, and at both ends of the mounting plate 111, protrusions 114 are formed longitudinally outward to be used for supporting the hydraulic cylinder 113, and the top of the hydraulic cylinder 113 is connected to the protrusion 114, so that the height position of the mounting plate 111 can be adjusted under the vertical extension and contraction of the hydraulic cylinder 113, thereby adjusting the height position of the extrusion plate 112.

[0047] Furthermore, it also includes an adjustment component 40 arranged below the flat roll 50, the adjustment component 40 includes a plurality of adjustment units arranged at intervals along the longitudinal direction, each of the adjustment units includes a roller 410 and two bearing seats 420 arranged opposite to each other in the transverse direction, wherein the bearing seats 420 are fixed on the base plate 30, and both ends of the roller 410 are rotatably connected to the bearing seats 420.

[0048] It should be understood that, since it is impossible to ensure that the elliptical major axis of the flat roll 50 is in a horizontal position when hoisting the flat roll 50, the adjusting component 40 can be additionally provided to rotate the flat roll 50 to adjust the placement position after the flat roll 50 is placed, and the adjusting component 40 includes a plurality of adjusting units spaced apart in the longitudinal direction, each of the adjusting units includes a roller 410 and two bearing seats 420 oppositely disposed in the transverse direction, and the flat roll 50 is synchronously rotated by rotating the rollers 410 until the elliptical flat roll 50 is rotated until the major axis of the ellipse is in a horizontal position; considering the installation space, the number of the adjusting units can be set to two, so that the two adjusting units are spaced apart in the longitudinal direction, and when hoisting the flat roll 50, the flat roll 50 can be evenly placed on the two rollers 410.

[0049] Furthermore, the bottom plate 30 has two longitudinal slide grooves 310 which are arranged opposite to each other in the transverse direction, and the support bracket 122 is movably connected to the longitudinal slide grooves 310 .

[0050] It should be noted that the longitudinal sliding groove 310 allows the support bracket 122 to be movably arranged, and can limit the sliding direction of the support bracket 122 to play a guiding role.

[0051] To facilitate understanding by those skilled in the art, the specific operation process is briefly described as follows:

[0052] First, the flat roll 50 is hoisted to the middle position on the roller 410, and the roller 410 is rotated so that the elliptical major axis of the flat roll 50 is in a horizontal position; then the hydraulic cylinder 113 is operated to lift the position of the mounting plate 111, thereby driving the position of the extrusion plate 112 to rise, so that the horizontal center plane of the extrusion plate 112 coincides with the plane where the elliptical major axis of the flat roll 50 is located, and the rounding preparation is completed; the driving component 221 (hydraulic motor and reducer) is operated to drive the double-headed screw 222 to rotate, and the two extrusion units are synchronously moved toward the flat roll 50 for extrusion (that is, the two extrusion plates 112 squeeze the elliptical major axis of the flat roll 50 toward the center) until the ideal size is reached, and then it stays for a period of time to complete the rounding work.

[0053] It is worth noting that before separating the two extrusion units, the extrusion disc 112, the double-headed screw rod 222, etc. will be lifted as a whole due to the rounding of the flat roll 50. Therefore, the hydraulic cylinder 113 should be lifted before rotating the hydraulic motor. The two extrusion units can be separated only after they contact the support point and are subjected to force to avoid falling in the air and injuring the operator and related equipment. After separation, the rounded steel ring can be lifted away.

[0054] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
