On-line servo cutting-to-length device for large-diameter PC steel bars

Abstract

Provided is an on-line servo cutting-to-length device for large-diameter PC steel bars. According to the on-line servo cutting-to-length device for the large-diameter PC steel bars, two rows of guide wheels of a trolley frame are arranged between upper cylindrical guide rails and lower cylindrical guide rails, the front end of the trolley frame is connected with a servo air cylinder, a shearing mechanism is arranged in the middle of the trolley frame, one end of a tie bar is connected with the rear end of a square knife platform, and penetrates through a locating part of a fixed length baffle, the other end of the tie bar is located by a clamping part arranged on wide guide rails, a vertical plate in the middle of a T-shaped connecting plate of the fixed length baffle is arranged in a gap between the two wide guide rails, a touch panel is arranged on the portion, in front of the fixed length baffle, of the tie bar, a photoelectric switch is arranged on the portion, in front of the fixed length baffle, of one wide guide rail, an upper horizontal rod corresponding to the gap between the two wide guide rails is connected with the upper end of two identical crank arms through a horizontal revolute pair, the lower ends of the two crank arms are connected with a lower horizontal rod, and the two ends of the lower horizontal rod are arranged in bearing blocks of two material bearing frames respectively. According to the on-line servo cutting-to-length device for the large-diameter PC steel bars, operation is easy, production efficiency is high, and the quality of cross sections of the PC steel bars and the accuracy of the fixed length of the sheared bars are effectively improved.

Description

technical field [0001] The invention relates to a hydraulic hammer type online fixed-length shearing device. Background technique [0002] In recent years, with the development of the economy, the construction industry has developed rapidly, and the demand for prestressed concrete pipe piles has further increased. Since a large number of PC steel rods are required in the production process of prestressed concrete pipe piles, the precise shearing of PC steel rods, especially large-diameter steel rods, has become a practical engineering problem that needs to be solved urgently. The traditional follow-up hydraulic shearing machine adopts the method of electronic sizing to set the cutting length of the bar. Due to the unavoidable delay of the control system, the accuracy of the length value of the cut bar is directly poor. Occasions even require secondary processing; at the same time, the traditional steel bar shearing machine has a complex structure and low production efficien...
