Description

Technical Field

[0001] The utility model belongs to the technical field of forging tool design, and specifically relates to a fast-switchable dual-purpose clamping claw for a forging press, which can greatly improve forging efficiency, reduce labor intensity and lower production cost. Background Art

[0002] Forging manipulators are mainly used to clamp forgings and cooperate with the main machine to complete the forging process. They are important equipment for free forging. The jaws are the executive parts of the manipulator to clamp forgings. According to the size of the clamped object and the convenience of operation, they can be divided into clamps and crab claws. The clamps are mainly used to clamp ingots or forgings with a weight of more than 2 tons or an effective cross-sectional size greater than 400mm, and to achieve upsetting, drawing, blanking, rotation, turning and other actions, such as clamping ingots, rotors, rolls, modules and other large-sized forgings. However, they cannot be used to clamp forgings with relatively small cross-sections below 400mm, while crab claws mainly clamp small-sized forgings, effectively clamping forgings with a thickness or diameter below 400mm, such as breech square steel, gear rings, and round cake forgings, which are more convenient to operate.

[0003] In actual production, the production situation is more complicated, and there are many types of forging products. When one or several heating furnace forgings are produced, other types of forgings need to be produced, so the jaws must be replaced frequently. For example, the first furnace completes the forging of large-sized forgings above 400mm, and the forgings in the second furnace are gear rings and pancakes. The warm forgings in the third furnace are also large-sized forgings. In this way, the clamp must be disassembled before the crab claw clamp is installed. After forging small-sized forgings, the crab claw clamp must be disassembled and the clamp must be installed. It takes at least 30 minutes to disassemble and reinstall once. During the replacement of tooling, the products can only wait for materials in the heating furnace, which seriously affects production efficiency, increases the labor intensity of workers, and does not take advantage of the company's quality cost control. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art such as frequent replacement of jaws, low production efficiency, high labor intensity, unstable quality and cost, etc. due to the differences in forging products, and to provide a dual-purpose jaw that can be quickly switched. By optimizing the structure of the main jaw arm of the manipulator, the jaw pad of the clamp and the part where the crab claw clamp is connected to the main jaw arm, when the jaw type needs to be switched, the jaw pad of the clamp does not need to be removed, and the crab claw clamp can be quickly installed or removed.
