Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings. Such as Figure 1-2 As shown, an upper anvil clamping device for a forging hydraulic press can realize quick replacement, rotation and clamping of the upper anvil during the operation of the forging hydraulic press. When the forging hydraulic machine is ready to work, fix the connecting block 12 on the upper anvil 3 and put it in place under the movable beam 1 of the hydraulic machine. The oil cylinder 4 is filled with hydraulic oil, and the piston 5 pushes the pull rod 9 to overcome the clamping force of the disc spring group 10 and move downward. , the pull rod 9 is a T-shaped structure. When the T-shaped head passes through the connecting block 12 and reaches the position, the proximity switch A17 sends a signal, and the oil cylinder 4 stops moving. After that, the hydraulic cylinder 14 pushes the connecting rod 13 to drive the rotating block 8 to rotate, and the rota...

Abstract

The invention discloses an anvil clamping device for a hydraulic forging press. The anvil clamping device for the hydraulic forging press comprises an oil cylinder, a piston, a flange, a cylinder cover, a rotary block, a pull rod, a disc spring group, a connection block, a connection rod, a hydraulic cylinder, a bracket, an induction rod, a proximity switch and a machine limit and thrust bearing. The anvil clamping device for the hydraulic forging press is mounted in the active girder of the hydraulic machine, the upward clamping force is offered by the disc spring group and the downward loosening force is offered by the oil cylinder, the connection rod is pushed by the hydraulic cylinder for rotating the anvil. The anvil is quickly clamped and rotated by the anvil clamping device, the anvil replacing time is greatly reduced, the forging production efficiency is greatly raised, and the work stability and reliability of anvil can be guaranteed, the safety of the device is raised. The anvil clamping device for the hydraulic forging press has important significance for raising the production efficiency, reducing the labor intensity for workers and guaranteeing safety and reliability of the device.

Description

technical field [0001] The invention relates to an upper anvil clamping device for a forging hydraulic press, belonging to the technical field of mechanical equipment. Background technique [0002] The forging hydraulic press is mainly used for upsetting, elongating, punching, reaming and other processes of metal. The upper anvil is an important auxiliary tool when the forging hydraulic press works. It needs to work stably and reliably during the production process, and according to the production process According to the requirements, the upper anvil should be replaced frequently and the rotary anvil operation should be carried out. The replacement time of auxiliary tools has always been an important factor restricting the production efficiency of forging hydraulic presses. At the same time, the clamping stability of the upper anvil is related to the safety of the equipment. How to realize the stable clamping and quick replacement of the upper anvil has been a problem that ...
