The invention discloses a press safety protection device. A buffer device is arranged on a cylinder; a pressure head is mounted in a step hole of the buffer device; hydraulic silica gels are arranged at the lower end of the pressure head and an inner cavity of the cylinder; powerful butterfly springs are symmetrically arranged at the two outer sides of the buffer device and on the cylinder; and pressure bolts are mounted in center holes of the powerful butterfly springs. The press safety protection device has the advantages of simple structure, quick disassembly, convenience for maintenance, quick response and quick buffer, and effectively overcomes the defects of complex structure, troublesome disassembly, inconvenience for maintenance, slow response and slow buffer in an existing press safety protection device.
Description
technical field [0001] The invention relates to a safety protection device, in particular to a press safety protection device, which belongs to the technical field of press safety equipment. Background technique [0002] In some presses, in order to prevent equipment safety accidents caused by overloading of important parts and equipment, safety protection mechanisms are generally installed at the corresponding load-bearing positions. Taking press machinery as an example, generally according to the different grades and structural models of the press A pressure fuse mechanism is installed in the slider, among which a collapsed fuse mechanism is installed in some low-grade and small and medium-sized pressure machines, and the protection mechanism is based on the damage of the fuse itself at a low price. Other important components and the entire machine equipment, and in large and other high-end presses, hydraulic safety mechanisms are generally used. The mechanism of this safe...
