Tong head rotating device for forging charging and taking machine

Abstract

The invention discloses a tong head rotating device for a forging charging and taking machine. The tong head rotating device comprises a rotating assembly used for controlling a tong head to rotate, the end of a clamping assembly used for controlling a pair of clamping arms to move is connected to one end of the rotating assembly, the center of the rotating assembly is connected with one end of a hollow shaft, the other end of the hollow shaft is connected with one end of a tong head shell through a flange plate, the other end of the tong head shell is connected with one end of each clamping arm through one of clamping arm pin shafts taking the hollow shaft as the symmetric axis, the clamping arms take the hollow shaft as the symmetric axis, and the other end of each clamping arm is hung in the air; and the clamping assembly penetrates through a central through hole of the hollow shaft to the inner side of the tong head shell and is connected with one end of each clamping arm through the corresponding clamping arm pin shaft. The tong head rotating device is used on the forging charging and taking machine and has the purposes that the tong head does plus and minus 360-degree rotation around the axis of the hollow shaft and then stops at a needed station, so that heated workpieces are taken out of the machine more quickly and more accurately from different directions.

Description

technical field [0001] The invention relates to a rotating device, in particular to a tong head rotating device of a forging loading and unloading machine. Background technique [0002] The forging loading and unloading machine is suitable for forging, rolling mill and heat treatment industries. It is matched with heating furnaces, various forging hammers and presses, and can realize the processes of billet out of the furnace, picking up materials, feeding materials, turning materials, etc., and can be used for multi-variety and small batch production. Replacing cumbersome manual operations has greatly improved the working conditions of industrial workers and increased productivity. The equipment can complete the following actions: cart walking, trolley walking, bench rotation, clamp rod telescopic, clamp rod lifting, clamp rod tilting, jaw clamping, clamp head rotation, in which the clamp head rotation is the forging loading and unloading machine. One of the main actions. ...

AI Technical Summary

Problems solved by technology

The existing clamp head rotation device is equipped with an isolating coupling between the pull rod and the piston rod. On the one hand, the rotation is not flexible enough to quickly and accurately remove the heated workpiece. On the other hand, the structure of the rotation device is complicated, and the equipment is increased. The failure rate increases the production cost and reduces the production efficiency
