The invention provides a device for gradually leveling conversion of hot rolled flat steel, which aims to solve the problem that a cooling bed or a chain type transverse shifting rack is required to be transited to be erected in the traditional flat steel, and realizes smooth conversion of the flat steel at the outlet of a rolling mill from a flat state to a vertical state. The invention discloses a hot-rolled flat steel progressive horizontal-vertical conversion device, which is characterized in that a horizontal-vertical conversion guide groove is adopted, the horizontal-vertical conversion guide groove consists of a guide groove retainer, a long roller and a short roller, a key groove with a progressive conversion angle is processed on the guide groove retainer, and the key groove is connected with a bracket through a key to realize the progressive conversion transition of the angle of the horizontal-vertical conversion device. The beneficial effects of the invention are as follows: the novel production line has the advantages of small occupied area, light weight and fast rhythm, can be applied to a newly designed production line, can be applied to the existing production line on the premise of not affecting the production of the existing production line, and is beneficial to product expansion.
Description
Technical Field
The invention belongs to the technical field of metallurgy, and relates to a device for gradual leveling conversion of hot rolled flat steel.
Background
After the flat steel is rolled, the outlet of the rolling mill is in a flat state, and the common production process is to cool the flat steel on a rack cooling bed or a chain type marshalling rack after the flat steel is delivered through a skirtboard roller way and then enter a rear working procedure.
For partial small bar production line, due to the structural limitation of the apron board roller way, the flat steel cannot share one set of apron board roller way with the small bar, and in order to realize the production of the flat steel, the flat steel at the rolling outlet needs to be transported to the position of the cold bed output roller way through the arc-shaped guide groove. For the reason of bending radius of the flat steel, in order to prevent the flat steel from irrecoverable shaping deformation, a set of progressive flat-stand conversion device is needed to realize smooth conversion of the flat steel at the outlet of the rolling mill from a flat state to a vertical state and directly enter a rear working procedure.
For part flange end plate production line, at present flat steel manufacturing enterprises all are through apron board roll table after down steel, get into low-order roll table and stand up the flat steel after carrying on chain marshalling rack, then get into the crimping process, this is equipment structure complicacy that sideslip rack, the investment is high, in addition, the cooling of marshalling rack influences the temperature of flat steel, increase the degree of difficulty of rear portion process, through setting up a set of progressive flat conversion equipment, cancel marshalling rack isotructure, realize rolling mill export flat steel and change to vertical state smoothly by flat state, directly get into rear portion process.
Disclosure of Invention
The technical problems solved by the invention are as follows: the flat steel at the outlet of the rolling mill is smoothly converted from a flat state to a vertical state by using less occupied area and less investment equipment, and the flat steel directly enters a rear working procedure.
The technical scheme adopted for solving the technical problems is as follows:
the progressive flat-standing conversion device for hot rolled flat steel is positioned behind a finishing mill, can directly realize the smooth conversion of flat steel at the outlet of the mill from a flat state to a vertical state, can directly enter a rear process, and can also be added with a section of reverse flat-standing conversion device at the outlet if the flat steel is required to be put flat again.
The invention relates to a hot-rolled flat steel progressive horizontal-vertical conversion device which consists of a first connecting lug seat, an inlet horn, a bracket, a base, a horizontal-vertical conversion guide groove, a second connecting lug seat, an outlet horn and a key. The core is that a horizontal-vertical conversion guide groove is adopted, and the horizontal-vertical conversion guide groove consists of a guide groove retainer, a long roller and a short roller, and the long roller and the short roller are connected with the guide groove retainer through bolts. The key grooves with different angles are processed on the guide groove retainer, the key grooves with the same angle are processed on the support, the guide groove retainer is connected with the support through the key, gradual transition of horizontal-vertical transition of the guide groove angle is achieved, and therefore flat steel entering the guide groove is gradually converted from a flat state to a vertical state. The conversion angle of each key groove can be changed according to the requirements of different product outline of the production line, and the conversion angle of each guide groove is between 1.5 and 4.5 degrees.
The beneficial effects of the invention are as follows: the novel production line has the advantages of small occupied area, light weight and fast rhythm, can be applied to a newly designed production line, can be applied to the existing production line on the premise of not affecting the existing production line, and is beneficial to product expansion. The invention can also be used for an end plate production line, eliminates complex steel feeding systems such as a grouping rack and the like, reduces temperature drop and smoothly realizes full-automatic production of the end plate.
