Press machine for Roman chair forming die

Abstract

The press machine for the Roman chair forming die comprises a power box, a cooling box, a junction box, power pipes and a piston cylinder, the bottom and the top of the power box are connected with the junction box and the cooling box respectively, the power pipes are embedded into the side face of the power box, and the bottoms of the power pipes are embedded into the two sides of the piston cylinder respectively. A fan and a plurality of sliding rings are fixed to the inner wall of the cooling box through supporting rods, supporting plates are fixed to the side faces of the sliding rings through supporting rods, sliding rods movably penetrate through the middles of the sliding rings, and the tops and the bottoms of the sliding rods are fixed to the moving plates and the connecting plates correspondingly. The mercury in the power box expands after being heated, the mercury expands to push the pressure column to move downwards in the piston barrel, the pressure is increased through thermal expansion and cold contraction of the mercury, the heated area of the mercury is very large, the mercury can be rapidly expanded, and compared with a pressure increasing mode of a traditional press, the pressure is increased very rapidly, the pressure column moves rapidly, and the energy consumption is reduced. And the processing efficiency of the pressure column is very high.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a press for forming molds for Roman chairs. Background technique [0002] The press is a general-purpose machine with exquisite structure. The press is a device for applying pressure and can be widely used in cutting, punching, blanking, bending, riveting and forming processes. The press is generally controlled by hydraulic pressure, lever and gear ratio. The three ways are to compress the mechanical energy little by little to generate huge pressure as the power of the press. The mechanical energy compression process is slow, resulting in the slow movement of the pressure column; [0003] Aiming at the technical enlightenment related to mechanical energy compression; [0004] At present, CN201911009021.9 in the prior art is a light-weight bellows type thermal expansion drive device, which discloses that the expansion medium absorbs heat and expands, and converts heat energy into...
