Description

Technical Field

[0001] The invention relates to the technical field of steel rolling auxiliary equipment, in particular to a square billet steel separating device matched with a square billet feeding process. Background Art

[0002] Existing billet steel separating devices are generally divided into two types. One is mainly used to transport billets from billet stands to transport rollers. Its main feature is that the billets are allowed to slide off the stands through inclined rails, and then the billets are sent to the transport rollers through steel separating wheels or steel shifting swing arms. In addition to the above uses, the other can also be used to lift billets from the transport rollers to billet stands. Its main feature is that it consists of a fixed car body and a movable car body. The movable car body can be lifted or swung as a whole on the fixed car body, and materials can be taken from the billet stand or the transport roller through the movement of the movable car body. The problems with the former are: (1) due to the existence of the slideway, the impact force of the billet on the equipment is very large. Even if a buffer device is installed, the surface of the billet is easily scratched during the sliding and steel-pulling process of the billet; (2) the rotation speed of the steel-dividing wheel cannot be too fast or too slow. For billets of different steel grades and temperatures, it is necessary to readjust, and the installation and commissioning are relatively cumbersome; the problem with the latter is that since the entire mobile vehicle body needs to be lifted or swung as a whole, the structure of this mechanism is relatively large, the equipment and civil engineering investment is relatively high, and the reset time after each loading is completed is relatively long. It is necessary to wait for the billet to completely detach from the conveyor roller before resetting and lifting the next billet. Therefore, it cannot match the higher production rhythm. In view of the above reasons, it is necessary to develop a billet steel-dividing device with a compact structure, high reliability, and the ability to avoid billet impact and surface scratches, which can be suitable for billets of various specifications and sizes, can meet various loading methods, and can meet a higher production rhythm. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a steel separation device which has a compact structure, does not scratch the surface of the steel billet, is suitable for square billets of various steel grades and specifications, can meet various feeding methods, and can improve the production rhythm.

[0028] The embodiments of the present invention will be described below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that the described embodiments may be modified in various ways or combinations thereof without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of the claims. In addition, in this specification, the drawings are not drawn to scale and the same reference numerals represent the same parts.

[0029] like Figure 1 , Figure 2 As shown, the billet separation device of this embodiment includes: a guide rail 11, a transverse transfer vehicle 5, a transverse transfer driving mechanism, a steel supporting swing arm 9, and a swing driving mechanism. The transverse transfer driving mechanism and the swing driving mechanism can be hydraulic cylinders, such as Figure 1 The traverse hydraulic cylinder 1 and the swing hydraulic cylinder 6 in the embodiment of the present invention are not limited thereto, and the embodiment of the present invention may also be, for example, a cylinder, a linear push rod, etc.

[0030] The lateral hydraulic cylinder support 3 and the guide rail support 12 are installed on the ground, and the guide rail 11 is horizontally installed above the guide rail support 12. The guide rail 11 is provided with two lateral limit blocks 10 spaced along its length direction, specifically, one is provided at the conveying roller 100, and the other is provided at the billet stand 200, which are used to limit the movement of the lateral vehicle so that it can stop at the conveying roller 100 and the billet stand 200. In addition, the guide rail 11 can be two or more spaced parallel guide rails.

[0031] The traverse hydraulic cylinder 1 is mounted on the hydraulic cylinder support 3. The traverse vehicle 5 may be equipped with, for example, four wheels, two on each side, which are arranged on the guide rail 11 or embedded in the guide rail 11 and can roll along the guide rail 11. The output end of the traverse hydraulic cylinder 1 is connected to the traverse vehicle 5, so that the traverse vehicle 5 can be driven to move forward or backward along the guide rail 11.

[0032] A transverse proximity switch 4 is installed on the transverse vehicle 5. The transverse proximity switch 4 can generate an induction signal with the transverse limit block 10, thereby sending a signal to the transverse hydraulic cylinder 1 to stop the transverse hydraulic cylinder 1, specifically, stop at the conveyor roller or the billet stand.

[0033] The steel supporting swing arm 9 and the swing hydraulic cylinder 6 are both installed on the transverse transfer vehicle 5. The steel supporting swing arm 9 is connected to the swing hydraulic cylinder 6 and can swing at a certain angle under the drive of the swing hydraulic cylinder 6 to lift or put down the square billet from the conveying roller or the square billet stand.

[0034] Figure 1 The steel support swing arm 9 is L-shaped, and is connected to the short side of the L-shape through the output end of the swing hydraulic cylinder 6, so that the steel support swing arm 9 is driven to swing through the swing hydraulic cylinder 6. The end of the long side of the L-shape of the steel support swing arm 9 is provided with a shape for supporting the billet, for example, the end includes a bottom plate 91 and a back plate 92 for supporting the billet. Preferably, the bottom plate 91 and the back plate 92 are connected in the form of an obtuse angle.

[0035] Two swing limit blocks 8 are also arranged on the steel supporting swing arm 9, and the swing limit blocks 8 are arranged at intervals along the swing arc of the steel supporting swing arm 9. The swing limit blocks 8 can generate an induction signal with the swing proximity switch 7 installed on the transverse shift vehicle 5, so that the swing hydraulic cylinder 6 stops moving, and the steel supporting swing arm 9 stops at the steel unloading height or the steel supporting height. Among them, as the steel supporting swing arm 9 swings, the bottom plate 91 is tilted downward outward at the steel unloading height, so that the billet will slide off the steel supporting swing arm 9 in this state, and at the steel supporting height, the bottom plate 91 is tilted downward inward, so that the billet will not slide off the steel supporting swing arm 9.

[0036] The working process of the billet steel separation device is explained below.

[0037] Transport the billet from the conveyor roller to the billet stand: the transverse transfer vehicle 5 is at the conveyor roller 100, and the swing drive mechanism drives the steel support swing arm 9 to swing and lift from the steel unloading height to lift the billet parked on the conveyor roller, and the bottom plate 91 is tilted downward inward so that the billet will not slide off the steel support swing arm 9. The swing limit block 8 and the swing proximity switch 7 sense and generate a signal, and the swing drive mechanism stops the action, so that the steel support swing arm 9 is suspended at the steel support height.

[0038] The transverse driving mechanism pushes the transverse vehicle 5 to move along the guide rail 11 toward the billet stand 200, the transverse limit block 10 senses and generates a signal with the transverse proximity switch 4, the transverse driving mechanism stops, the transverse vehicle 5 stays at the billet stand 200, and the swing driving mechanism drives the steel support swing arm 9 to fall, so that the bottom plate 91 of the steel support swing arm 9 is tilted outward and downward, so that the billet slides off the steel support swing arm 9 in this state and falls onto the billet stand 200. The steel support swing arm 9 continues to fall, the swing proximity switch sends a signal, the steel support swing arm returns to the steel unloading height, and the transverse driving mechanism drives the transverse vehicle back to the conveyor roller.

[0039] The billet is delivered from the billet stand to the conveyor roller: the transverse transfer vehicle is at 200 of the billet stand, the swing drive mechanism drives the steel supporting swing arm 9 to swing and lift from the steel unloading height, and the billet parked on the billet stand is lifted, the swing limit block 8 and the swing proximity switch 7 sense and generate a signal, and the swing drive mechanism stops moving, so that the steel supporting swing arm 9 is suspended at the steel supporting height.

[0040] The transverse driving mechanism pushes the transverse vehicle 5 to move along the guide rail 11 toward the conveyor roller 100, the transverse limit block 10 and the transverse proximity switch 4 sense and generate a signal, the transverse driving mechanism stops moving, the transverse vehicle 5 stays at the conveyor roller 100, the swing driving mechanism drives the steel supporting swing arm to fall, and parks the square billet on the conveyor roller, the steel supporting swing arm 9 continues to fall, the swing proximity switch 7 sends a signal, the steel supporting swing arm returns to the steel unloading height, and the transverse driving mechanism drives the transverse vehicle back to the square billet stand.

[0041] Furthermore, a drag chain 2 is provided, which is placed on the ground and connected to the transverse moving vehicle 5 at one end, and can drive the hydraulic pipes of the transverse moving hydraulic cylinder 1 and the swing hydraulic cylinder 6 to move forward or backward with the transverse moving vehicle 5.

[0042] It should be noted that the above description is based on one set of billet separation device as an example. In order to ensure stable transfer, multiple sets of billet separation devices can also be provided, which can be arranged in the space between the rollers of the conveyor roller as needed.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
