Automatic stokehold round steel bar feeding device for continuous heating furnace

Abstract

An automatic stokehold round steel bar feeding device for a continuous heating furnace is composed of a stokehold storage platform, a feeding platform, chain lifters and a control device. The height of the stokehold storage platform is matched with that of a furnace door of the continuous heating furnace, and the height of the feeding platform is smaller than that of the stokehold storage platform; the lower end of each chain lifter is installed at the front end of the feeding platform, the upper end of each chain lifter is installed at the rear end of the stokehold storage platform, and the two chain lifters are arranged in parallel and operate synchronously; lifting grabs are installed on chains of the chain lifters, and a jacking cylinder is installed on the feeding platform. Compared with the prior art, automatic correction feeding lifting of round steel bars can be carried out according to the tapping time of the continuous heating furnace, the round steel bars are arrayed in a line, feeding is automatically stopped after the round steel bars reach a set upper limit position, and bar lifting is automatically carried out after the round steel bars reach a lower limit position in the lowering process.

Description

technical field [0001] The invention relates to a continuous heating furnace, in particular to an automatic round steel feeding device in front of the continuous heating furnace. Device for automatic feeding of round steel into continuous heating furnace. Background technique [0002] At present, during the forging production process of steel balls, the round steel must be continuously hoisted into the heating furnace. After the round steel is heated to the set temperature, it is cut into short billets by a bar shearing machine, and then forged by an air hammer. , but in the process of feeding the round steel, it is necessary to hoist the bundled round steel to the heating furnace platform for loading. Due to the narrow working space of the heating furnace platform and inconvenient operation, there are serious safety hazards. During the feeding process, because the heating furnace has a certain slope, the round steel is crowded forward and cannot be lined up, resulting in i...

Problems solved by technology

[0002] At present, during the forging production process of steel balls, the round steel must be continuously hoisted into the heating furnace. After the round steel is heated to the set temperature, it is cut into short billets by a bar shearing machine, and then forged by an air hammer. , but in the process of feeding the round steel, it is necessary to hoist the bundled round steel to the heating furnace platform for loading. Due to the narrow working space of the heating furnace platform, the operation is inconvenient for personnel, and there are serious safety hazards. During the feeding process, because the heating furnace has a certain slope, the round steel is crowded forward and cannot be lined up, resulting in inclined steel and stacked steel, which need to be corrected manually with a sledgehammer before entering the heating furnace for heating, and Operators have to carry out round steel feeding and calibration continuously with the tapping time. The labor intensity of employees is high, and continuous shifts are required to perform operations, resulting in increased manpower operating costs.
