Abstract
The invention discloses an online servo large-diameter bar hydraulic follow-up fixed-length shearing mechanism. The online servo large-diameter bar hydraulic follow-up fixed-length shearing mechanism mainly comprises a fixed bracket, a hydraulic shearing machine, a mechanical connecting mechanism and a bearing frame, wherein the fixed bracket mainly comprises a left bracket, a right bracket, a shearing machine guide rail, a guide sleeve, a photoelectric sensor and the like. The hydraulic shearing machine mainly comprises a hydraulic cylinder, an upper cutting knife, a lower cutting knife, a shearing machine roller, a speed measuring support wheel and a bracket. The bearing frame mainly comprises an upper bracket, a lower horizontal rod, a lower bracket, a lower bracket roller, a linear guide rail, a wide guide rail, a baffle rod, a turning arm, a bracket and a fixed-length baffle plate. The mechanical connecting mechanism comprises a servo motor, a gear, a rack, a connecting rod and a touch plate. The online servo large-diameter bar hydraulic follow-up fixed-length shearing mechanism can largely quicken the bar speed to realize high-speed online production, and prevents secondary processing and resource waste to achieve high practical value.
Description
technical field [0001] The invention relates to a bar shearing device in the metallurgical industry. Background technique [0002] Because large-diameter bars are mostly used to build factory buildings, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., with the development of the economy, their demand is increasing year by year, but their production efficiency and sizing accuracy are the limit. The bottleneck of industry development has become an engineering problem that needs to be solved urgently. At present, the shearing method of large-diameter bar shears mainly uses hydraulic presses to drive blades for shearing, which is slow, inefficient, and cannot be processed on-line in real time. The shearing production line does not consider whether the large-diameter bar can accurately enter the material holder again after completing a shearing process. Due to the unconstrained shaking of the front section of the bar, it is bound to affect ...
