Forging manipulator lifting mechanism with inclined rear suspension rods

Abstract

The invention relates to a forging manipulator lifting mechanism with inclined rear suspension rods in the technical field of the mechanical engineering, which is characterized in that the upper ends of two front suspension rods (12) are respectively connected at the lower ends of two front connecting pieces (9) by rotating hinges; the upper ends of the two front connecting pieces (9) are respectively connected on both sides of a movable frame (10) by rotating hinges; the movable frame (10) can move left and right on a front sliding rod (7); two rear suspension rods (16) are arranged symmetrically right and left in an inclined mode; the upper ends of the two rear suspension rods (16) are respectively connected at the lower ends of two rear connecting pieces (17) by rotating hinges; the upper ends of the two rear connecting pieces (17) are respectively connected on both sides of a rear sliding rod (2) by rotating hinges; two pitching linear drivers (4) are horizontally arranged on the top of a lifting arm front and back; and the front ends of the two pitching linear drivers (4) are respectively connected on both sides of a front lifting arm (6) by spherical hinges, while the rear ends thereof are respectively connected on both sides of a rear lifting arm (1) by spherical hinges. The forging manipulator lifting mechanism with the inclined rear suspension rods has the characteristics of high bearing capability, easy installation, long service life and the like and is suitable for forging operation of large-scale / ultra large forgings.

Description

technical field [0001] The invention relates to a device in the technical field of mechanical engineering, in particular to a lifting mechanism for a rear suspension rod inclined type 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 cylinders. 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 mech...

Problems solved by technology

However, the rear suspension part of this manipulator has only one rear suspension rod connected to the rear of the clamp rod with a ball joint. The rear suspension rod and the connecting ball joint are under too much force, which reduces the overall bearing capacity of the manipulator.

At present, there are also some large-scale forging manipulators whose rear suspension part uses two rear suspension rods to connect with the rear of the clamp rod, but these mechanisms are over-constrained and difficult to install, and if there are manufacturing and installation errors and elastic deformation caused by heavy load, Can cause internal stress on critical components, reducing their service life
