Inclined wedge swing rod type hydraulic machinery jaw

Abstract

The invention relates to an inclined wedge swing rod type hydraulic machinery jaw, which comprises a jaw fan-shaped plate, wherein a movable jaw and the jaw fan-shaped plate form a hinged connection through a centering shaft, the inner side of the movable jaw and a jaw top rod driven by a hydraulic and mechanical drive system are connected, the hinged connection end of the movable jaw is positioned on a position close to the outer edge of the jaw fan-shaped plate, and the free end is positioned on a position away from the outer edge of the jaw fan-shaped plate. According to the inclined wedge swing rod type hydraulic machinery jaw, with the structure, the hydraulic pushing part and the mechanical inclined wedge swing rod type jaw are combined during work to amplify the clamping force of the jaw on the thick plate so as to clamp the thick plate, and the tension load applying on the thick plate makes the movable jaw be tightly close to the fixed jaw during the cylinder and plate rolling process of the thick plate so as to make the jaw clamping force firm, such that the problem that the thick plate coiling jaw clamping force is insufficient so as to not to carry out acid washing on the thick plate with the thickness of more than 6 mm is solved.

Description

technical field [0001] The invention relates to a reel of a coiler, in particular to a wedge swing rod type hydraulic mechanical jaw for clamping plates. Background technique [0002] The reel jaws of the coiler currently used in pickling equipment can only meet the requirements of a plate thickness below 6mm. [0003] Chinese patent 200810235559.7 discloses a hydraulic jaw of a coiler, which uses a hydraulic cylinder to push the jaws to move linearly to achieve clamping. The existing problem is that during the coiling process, the hydraulic cylinder needs continuous liquid supply to maintain the clamping force, and energy consumption High, and due to the possibility of leakage in the hydraulic system, this clamping method is not reliable enough during the entire working process of the coiler. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a wedge swing rod type hydraulic mechanical jaw, which can ensure the co...
