Up-down rotary display stand for forging steel ingot

Abstract

A lift / rotation bench for forging steel ingots is provided, which belongs to the field of forging tools. The steel ingot-turning device in the prior art has the disadvantages such as offset load of the hoist cylinder during the placement of steel ingots and single V-shaped structure of the steel ingot supporter. In the invention, a reticulated V-shaped steel ingot supporter is connected with a frame of the lift / rotation bench and also supported against the top end surface of a thrust bearing; the thrust bearing is connected with a bearing block; the bearing block is connected with a spherical joint through a clamping block; the spherical joint is connected with a hoist cylinder; a rotary guide bracket is fixed thereon with a guide key; the guide key is in socket joint with a guide groove on the lift / rotation bench; the rotary guide bracket is fixed to the outer ring of a turntable bearing; the external teeth of the turntable bearing are engaged with a pinion gear; the pinion gear is driven by a variable motor, a supporter is fixed to the inner ring of the turntable bearing and positioned above a spring; and the supporter is arranged on a pedestal. The bench overcomes the problem of offset load of the hoist cylinder, avoids the failure of the oil cylinder, improves the work efficiency, and widens the range of forging specifications of steel ingots.

Description

technical field [0001] The invention relates to a forging tool, in particular to a tool for turning around a steel ingot blank during a forging operation. Background technique [0002] The steel ingot lifting and rotating table is a transitional device between the forging main machine and the manipulator. During forging, the crane hoists the steel ingot blank to be forged on the steel ingot lifting and rotating table, and then the steel ingot is clamped by the manipulator and sent to the main machine for forging. Due to technological requirements, the steel ingot blank often needs to be forged in a U-turn. The forged end is clamped by the manipulator and moved out of the main machine, and placed on the steel ingot lifting and rotating table. After being rotated, it is clamped by the manipulator into the main machine for forging. At present, most of the forging equipment in the entire forging industry in China was manufactured in the late 1950s and early 1960s, and the level...

AI Technical Summary

Problems solved by technology

The steel ingot U-turn device in the prior art can lift and rotate, but because the lifting is a rigid connection, when the steel ingot is placed on the U-turn device, its center of gravity cannot be guaranteed to fall on the center of the device, so there is an eccentric load on the lifting cylinder. As a result, the seal of the oil cylinder will be damaged, and the piston rod of the oil cylinder will be bent and deformed, resulting in failure of the oil cylinder and affecting work efficiency

In addition, the steel ingot U-turn device in the prior art has a single V-shaped support frame for the steel ingot, which limits the specification range of the steel ingot forging
