Technical Field

[0001] The present application relates to the technical field of rolling mills, and in particular to a vertical rolling mill having a drive unit. Background Art

[0002] Vertical roller mill is a kind of equipment used for metal rolling processing. The metal blank passes through the gap between one or more pairs of vertical rotating rollers to achieve the effect of reducing the width and increasing the length. In recent years, with the continuous development of high-precision rolling technology, advanced processes and rolling mills for improving product precision have been continuously introduced;

[0003] For example, an improved finishing vertical roller mill with announcement number CN220092525U, the rolled piece passes horizontally through the rolling channel between the upper and lower rollers, and is fully rolled under the action of the vertical rollers on both sides, which is simple to operate, has good processing efficiency and low production cost;

[0004] However, during the rolling process of this device, the billet needs to be rolled by horizontal rolls and vertical rolls. The metal of the billet tends to flow in the rolling direction, resulting in obvious deformation of the end, forming an end similar to a "fish tail", and the forming rate needs to be improved. Utility Model Content

[0005] In view of this, the purpose of the present application is to provide a vertical rolling mill with a drive unit, so as to limit the end of the billet to achieve the effect of controlling its deformation and improve the forming rate.

[0006] In order to solve the above technical problems, this application provides the following technical solutions:

DETAILED DESCRIPTION

[0027] like Figure 1 , Figure 2 , Figure 3 A vertical rolling mill of a drive unit shown in the embodiment of the present application comprises a main support 1 and auxiliary supports 2 on both sides thereof, mounting seats 3 are clamped on both sides of the top of the main support 1, rollers 301 are clamped inside the mounting seats 3, a hydraulic cylinder 101 is fixedly connected to the top of the side wall of the main support 1, a support plate 4 is fixedly connected to the end of the hydraulic cylinder 101, the support plate 4 comprises a horizontal support portion passing through between two rollers 301, a limit plate 401 is hingedly connected to the top of the support plate 4, a forming groove is provided on the side wall of the limit plate 4, a strip hole is opened on the top of the support plate 4, a limit slider 402 which can slide in the vertical direction is provided inside the top strip hole of the support plate 4, the limit slider 402 comprises an inclined surface facing the main support 1, and a guide roller 403 is provided at the end of the support plate 4;

[0028] The support plate 4 passes through the roller gap between the two rollers 301, and supports the stock passing through the roller gap, which can reduce the downward bending of the stock and improve the forming effect of the stock. At the same time, the limit plate 401 is hinged to the top of the support plate 4, and the limit plate 401 is driven by the hydraulic cylinder 101 to fit the end of the stock. When the end of the stock is deformed, the limit plate 401 is squeezed, and the end of the stock is kept flat by the limit plate 401;

[0029] At the same time, a forming groove is provided at the end of the limiting plate 401, which can further limit the deformation direction of the blank, define the shape and position of the end of the blank, and improve the forming rate.

[0030] In this embodiment, Figure 2-Figure 6 As shown: two limit plates 401 are hinged at the two end corners of the top of the support plate 4, and the two limit plates 401 are hinged to the support plate 4 through the rotating shaft 4011, and the sum of the widths of the two limit plates 401 is the same as the width of the support plate 4;

[0031] The two limit plates 401 are abutted against each other as a whole, and have a smooth and flat surface. When the billet enters the roller gap, the limit plate 401 can abut against the billet to timely control the shape of the end of the billet. As the hydraulic cylinder 101 drives the supporting plate 4 to move along the billet feeding direction, the supporting plate 4 and the limit plate 401 are driven to move synchronously with the billet. The supporting plate 4 abuts against the bottom of the billet. At the same time, the limit plate 401 maintains a 90° angle with the supporting plate 4, keeping the limit plate 401 in contact with the end of the billet, thereby ensuring that the end of the billet is evenly stressed and improving the forming rate.

[0032] A torsion spring 4012 is provided between the supporting plate 4 and the limiting plate 401, and the torsion spring 4012 is sleeved on the outside of the rotating shaft 4011;

[0033] The supporting plate 4 moves in contact with the upper surface of the main support 1. As the hydraulic cylinder 101 drives the supporting plate 4 to move away from the main support 1, the limiting slider 402 moves to the edge of the upper surface of the main support 1. The inclined surface of the limiting slider 402 contacts the edge of the upper surface of the main support 1, so that the limiting slider 402 moves downward under the action of its own gravity. The limiting slider 402 gradually breaks away from the contact with the limiting plate 401. When the upper surface of the limiting slider 402 is flush with the lower surface of the limiting plate 401, the limiting plate 401 can be turned toward the edge of the supporting plate 4, so that the blank can pass through the limiting plate 401, and the continuous feeding of the blank is maintained;

[0034] When the blank is out of contact with the limiting plate 401 , the limiting plate 401 can be reset under the action of the torsion spring 4012 .

[0035] The outer wall of the limiting slider 402 is provided with a groove, the side wall of the top strip hole of the supporting plate 4 is provided with a limiting step 404, and the limiting slider 402 is sleeved on the outer side of the limiting step 404;

[0036] The limiting slider 402 is limited by the limiting step 404 , which can prevent the limiting slider 402 from being separated from the supporting plate 4 .

[0037] A fixing seat 4021 is fixedly connected to the bottom of the side wall of the limiting slider 402, a return spring 4022 is fixedly connected to the top of the fixing seat 4021, and the bottom of the return spring 4022 abuts against the bottom of the supporting plate 4;

[0038] The return spring 4022 is used to squeeze the limit slider 402 to ensure that the limit slider 402 can release the limit on the limit plate 401 in time, thereby ensuring the continuous feeding of the blank.

[0039] The distance between the vertex of the guide roller 403 and the upper surface of the support plate 4 is 2 mm;

[0040] The guide roller 403 supports the blank and avoids direct sliding friction between the blank and the supporting plate 4, thereby keeping the lower surface of the blank smooth.

[0041] A second hydraulic cylinder 302 is disposed on one side of the mounting base 3 facing the secondary bracket 2, and the other end of the second hydraulic cylinder 302 is fixedly connected to the secondary bracket 2;

[0042] A servo motor 303 is fixedly connected to the bottom of the mounting seat 3, and an output end of the servo motor 303 is fixedly connected to the roller 301;

[0043] The servo motor 303 is used to keep the roller 301 rotating at a uniform speed to achieve a good rolling effect. The hydraulic cylinder 302 is used to control the position of the roller 301, control the size of the roller gap, and adapt to the width of the blank.
