Description

Technical Field

[0001] This application belongs to the technical field of steel plate production, and particularly relates to a steel plate straightening device. Background Art

[0002] The steel plate is bent due to overload, impact force, manufacturing, or the material itself. When the steel plate is slightly bent, the flattening method can be used for leveling. The thermal straightening method is applicable to the case where the steel plate is severely bent. The specific method is to heat the bent part to make it in a plastic state, and then apply pressure for shaping.

[0003] Therefore, when straightening the steel plate, different leveling methods are adopted according to different degrees of bending. However, this means that two sets of equipment are required to straighten the steel plate, so two sets of equipment and corresponding sites need to be prepared, resulting in an increase in equipment and its usage costs.

[0029] This embodiment provides a steel plate straightening device, including:

[0030] A conveyor assembly 10, which is a double-speed chain conveyor line composed of two chains 11, a driving sprocket set, a driven sprocket set, a driving electric mechanism, and a conveyor support 12. This kind of structure is a well-known structure in the art and will not be elaborated here.

[0031] The heated conveying plate assembly 20, the conveying plate assembly 20 includes several plate members 21 and connecting blocks 22 located at both ends of the plate members 21. The connecting blocks 22 are respectively fixed on the adjacent chains 11. The steel plate is placed on the upper surface of the plate members 21. The several plate members 21 are arranged at intervals and are driven by the conveying assembly 10 to transport the steel plate; heating wires 23 for heating the plate members 21 are provided in each of the plate members 21. The heating wires 3 are connected in series with each other, and the connection ends of the heating wires to the power supply can be connected through a circuit rotary connector to cooperate with rotary power supply.

[0032] The conveying plate support assembly 30, the conveying plate support assembly 30 is located inside the conveying bracket 12 and is used to support the plate members 21. Specifically, it includes several conveying rollers 31 rotatably arranged inside the conveying bracket 12, and the upper surface of the conveying rollers 31 abuts against the lower surface of the plate members 21.

[0033] The pressing-down assembly 50, the pressing-down assembly 50 includes a hydraulic cylinder 51, a lower pressing plate 52, and several pressing-down rollers 53 located above the conveying plate assembly 10. The lower pressing plate 52 is installed below the hydraulic cylinder 51, and several pressing-down rollers 53 are rotatably installed below the lower pressing plate 52, and the rolling direction is the same as the conveying direction of the conveying assembly 10;

[0034] The heating assembly 60, the heating assembly 60 includes an outer casing 61 located on the outer cylinder of the hydraulic cylinder 51. Several heating tubes 62 are installed on the inner side surface of the outer casing 61. Inlets and outlets 63 for facilitating the entry and exit of the steel plate are provided at both ends of the outer casing 61, and curtain doors 64 are provided in the inlets and outlets 63.

[0035] The curtain door 64 includes several curtain sheets 641. The curtain sheets 641 are divided into two groups. The first group of curtain sheets are installed at intervals on the inlets and outlets, and the second group of curtain sheets are located on the outer side surface of the first group of curtain sheets and are used to block the interval gaps of the first group of curtain sheets. The curtain sheets are made of rubber material. Such a design of the curtain door 64 can reduce the loss of heat from inside the outer casing 61, and at the same time, it is also to prevent the steel plate from passing through the outer casing 61.

[0036] In order to quickly shape the heated steel plate, heat dissipation fans 70 are respectively provided at the vacant positions inside both ends of the conveying assembly 10.

[0037] Advantages of the present utility model:

[0038] It is used for leveling when the steel plate is slightly bent. At this time, the steel plate is placed on the heating conveyor plate assembly, that is, on the plate on the upper surface. The conveyor assembly drives the plate to be conveyed under the lower pressing roller. At this time, the hydraulic cylinder drives the lower pressing roller to press down the steel plate for cold straightening. When it is used for a severely bent steel plate, start the heating wire and the heating assembly during use. When the plate is hot enough and the lower pressing roller in the heating assembly is also hot enough, place the steel plate on the heating conveyor plate assembly and convey it directly below the lower pressing assembly. Then the conveyor assembly stops conveying to make the steel plate in a plastic state. After a while, continue to convey. At this time, the lower pressing roller and the plate cooperate to press the bent steel plate for shaping.

[0039] Enlightened by the ideal embodiments according to the present application above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
