Fixed-length cutting device for flat steel on-line straightening

Abstract

The invention relates to a fixed-length cut-off device for online flat steel straightening. The fixed-length cut-off device for online flat steel straightening comprises a straightener and a platy support. The discharging side of the straightener is provided with a cut-off mechanism. One end of the platy support is connected with the discharging side of the straightener. The cut-off mechanism is located on the platy support. The fixed-length cut-off device is characterized by further comprising a controller, and a power mechanism and the cut-off mechanism are both connected with a controller through wires. A chain wheel shaft is arranged on the discharging side of the straightener and provided with a main chain wheel. The end, close to the straightener, of the platy support is provided with a first pair of supports. A first lower wheel shaft, an auxiliary chain wheel, a first pressing wheel, an electromagnetic clutch and a first gear are arranged between the first pair of supports. A transmission chain is connected between the auxiliary chain wheel and the main chain wheel. The electromagnetic clutch is connected with the controller through a wire. The platy support is provided with a second pair of supports. A second lower wheel shaft and a second gear are arranged between the second pair of supports, the first gear and the second gear are engaged with a rack, and the front end of the rack is connected with the cut-off mechanism. The tops of the first pair of supports are provided with an upper wheel shaft and a second pressing wheel. By the adoption of the fixed-length cut-off device, the production efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a flat steel straightening machine. Specifically, it is a device used to cut the straightened flat steel to a fixed length during the online straightening process of the flat steel. Background technique [0002] At present, in the field of steel production, in the process of straightening coiled flat steel into straight strips, it is necessary to cut the straightened flat steel into required lengths. In order to ensure that the cutting degree is consistent, the traditional method is to stop the straightening machine after the strip flat steel coming out of the straightening machine reaches the set length, and use a cutting device to cut a section. Then, start the straightening machine again, and when the strip-shaped flat steel coming out of the straightening machine reaches the set length, cut another section. According to the straightening section by section, section by section interception. Although adopting this method c...

Problems solved by technology

Although this method can ensure the consistency of the length of the cut flat steel straight strips, the straightening machine needs to be started and stopped many times continuously, which makes the production efficiency low
