A lifting mechanism of a large tonnage trackless forging manipulator

Abstract

The invention discloses a large-tonnage lifting mechanism for a trackless forging manipulator. The front portion and the rear portion of a main clamp shaft are fixedly connected with a front cross bar and a rear cross bar respectively, the two ends of a front connection bar are hinged to the front cross bar and a front hanging bar, and the two ends of a rear connection bar are hinged to the rear cross bar and a rear hanging bar. A left-to-right horizontal buffering cylinder is fixedly connected to the front portion of the main clamp shaft, and the two ends of the left-to-right horizontal buffering cylinder abut against the front hanging bar. The other end of the front hanging bar and the other end of the rear hanging bar are connected with the front endpoints and the rear endpoints of a pair of triangular frames, and inclined cylinders are connected with the lower endpoints of the triangular frames and a machine frame. Upper connection bars are connected with the front endpoints of the triangular frames and the machine frame. A front-to-back horizontal buffering cylinder is connected with the front hanging bar and the machine frame. Lifting cylinders are hinged to the middle portions of the upper connection bars and the machine frame. The large-tonnage lifting mechanism is symmetrically distributed with the main clamp shaft as the center and is simple in structure, good in synchronism and high in bearing capacity, the lifting motion trail of a clamp is close to a straight line, the position accuracy is high, and the view of a driver control console is wide.

Description

Technical field [0001] The invention relates to a forging operation device, in particular to a trackless forging operation machine. Background technique [0002] Forging manipulator is one of the important equipment for forging workshop to realize forging mechanization and automation. It is used in conjunction with forging hydraulic press to improve forging quality and production efficiency. At present, forging manipulators are divided into trackless forging manipulators and track forging manipulators. The rail forging manipulator is installed next to the forging hydraulic press, and the range of activities and the forging equipment to be served are determined. The trackless forging manipulator has a wide range of activities and good maneuverability. It can serve multiple forging equipment. The driver's console is set on the forging manipulator, which can operate the forgings as well as the transportation work of the forging workshop. After searching, it is found that the exist...

AI Technical Summary

Problems solved by technology

After searching, it was found that the existing trackless forging manipulators transformed from forklifts, loaders, and loaders had poor rigidity and small carrying capacity

The Chinese patent with the publication number CN2476368Y discloses a trackless forging manipulator, which adopts the synchronous movement of the front and rear electric hoists to make the clamps move up or down, with poor synchronization, poor stability of the steel wire rope suspension structure, and small bearing capacity

The British patent with the publication number UKGB1333299 discloses a trackless forging manipulator. When it is lifted, it is difficult to keep the clamps up and down horizontally, and the structure is complex and the load capacity is small.

The Chinese patent with the publication number CN102728764A discloses a parallel link type forging manipulator lifting mechanism, which improves the carrying capacity of the forging manipulator. Above ground, not suitable for trackless forging manipulators
