Lifting mechanism of forging manipulator

Abstract

The invention relates to a lifting mechanism of a forging manipulator in the mechanical engineering technical field. The lifting mechanism is characterized in that the upper ends of two front suspension rods (12) are separately connected with the lower ends of two front connecting parts (9) through swivel hinges arranged in the front-back horizontal direction of axes, the lower ends are separately connected with the left and right sides of the front part of a claw beam (14) through spherical hinges, the upper end of a back suspension rod is connected with the lower end of a back connecting rod (17) through a swivel hinge arranged in the front-back horizontal direction of axis, the connecting parts (9) and the back connecting part (17) are separately connected with a front sliding rod (7) and a back sliding rod (2) through swivel hinges arranged in the left-right horizontal direction of axes; and two pitching linear drivers (4) are horizontally arranged in the front and back of the top of a lifting arm, the front ends of the drivers are separately connected with the two sides of a front lifting arm (6) through swivel hinges, and the back ends are separately connected with the two sides of a back lifting arm (1) through swivel hinges. The invention is characterized in that the installation is convenient, the structure is simple, and the forging quality of forgings is easy to ensure.

Description

technical field [0001] The invention relates to a device in the technical field of mechanical engineering, in particular to a lifting mechanism of a forging manipulator used for free forging. Background technique [0002] The forging manipulator is one of the basic tools for large-scale forging pressure processing, and it is used in conjunction with the press. Generally speaking, the forging manipulator needs to realize seven forging operation functions including jaw clamping, tong bar rotation, tong bar lifting, tong bar pitching, tong bar lateral movement, tong bar swing, and cart travel. Among them, the three actions of jaw clamping, clamp rod rotation, and cart walking are independent from each other in structure, and are respectively driven by motors or hydraulic pressure. The clamp realizes the clamping and rotating functions of the workpiece, and the cart undertakes the traveling function. The action is realized by the lifting mechanism.

However, this manipulator is used to realize the pitching movement of the manipulator. The pitch hydraulic cylinder is arranged in the vertical direction. The lower end is connected to the rear of the clamp rod, and the upper end is directly connected to the swing device to realize the lateral movement and swing movement, so the installation is difficult.

In addition, this kind of forging manipulator cannot realize the lateral movement function due to the rear suspension part. When realizing the left and right buffer movement, the front suspension part needs to move on the front slide bar as a whole, and at the same time there will be coupling movement of the clamp rod swing and pitching , not only increases the complexity of the structure, but also reduces the forging quality of the forging
