Model utility content
This practical purpose is to provide a kind of safety installations to improve the operating security of press machine, prevents that operator from coming to harm.
For achieving the above object, the technical solution adopted in the utility model is: a kind of safety installations of press machine, comprise upper beam and lower support, there is column between the two, between upper beam and lower support, on column, moved cross beam is being set, die set A is arranged on lower support, top die B is arranged on the lower face of moved cross beam, between upper beam and moved cross beam, be connected with pneumatic power mechanism, on upper beam, be provided with cylinder, it is fastening that the piston rod of cylinder stretches out plate face and the moved cross beam upper board face of upper beam, during moved cross beam rising homing action, cylinder starts and provides pulling force upwards to hold up moved cross beam.
Compared with prior art, there is following technique effect in the utility model: at upper beam, cylinder is set, the tailpiece of the piston rod of cylinder and the upper plate surface of moved cross beam are fastening, moved cross beam reset lifting and when static, cylinder starts support and plays moved cross beam, prevents the fracture due to moved cross beam and power mechanism link position place, causes unexpected the falling of top die on moved cross beam and moved cross beam, operator is shone into injury, improve the safety in utilization of press machine.
Accompanying drawing explanation
Fig. 1 is axonometric drawing of the present utility model.
Embodiment
In conjunction with Fig. 1, the utility model is done further to understand.
A kind of safety installations of press machine, the structure of press machine comprises upper beam 10 and lower support 20, there is column 30 between the two, between upper beam 10 and lower support 20, on column 30, moved cross beam 40 is being set, die set A is arranged on lower support 20, top die B is arranged on the lower face of moved cross beam 40, between upper beam 10 and moved cross beam 40, be connected with power mechanism, power mechanism is to provide the pneumatic or hydraulic pressure installation that ouput force is larger, power mechanism is arranged on upper beam 10, stretch out the piston rod of upper beam 10 and the upper board face of moved cross beam 40 is fastening, offer the lower pressure power of upper beam 10.On upper beam 10, be also provided with cylinder 50, it is fastening that the piston rod of cylinder 50 stretches out plate face and the moved cross beam 40 upper board faces of upper beam 10, moved cross beam 40 rising homing actions or when static, cylinder 50 starts and the pulling force upwards moved cross beam 40 of slinging is provided, prevent the fracture due to moved cross beam 40Yu pneumatic power mechanism's link position place, cause unexpected the falling of top die B on moved cross beam 10 and moved cross beam 10, operator is shone into injury, improve the safety in utilization of press machine.
Further, as preferred version of the present utility model, in conjunction with Fig. 1, the vertical setting of plate face of the piston rod length direction of described cylinder 50 and moved cross beam 40, thus guaranteed that the direction of power and the plate face of moved cross beam 40 of cylinder 50 outputs are vertical.
Shown in Fig. 1, described pneumatic spring 50 is cylinder 50, the cylinder body of cylinder 50 is arranged on the plate face of upper beam 10, the tailpiece of the piston rod of cylinder 50 stretches out the plate face of upper beam 10 and fastening with the upper board face of described moved cross beam 40, preferred version as this programme, the upper plate surface of moved cross beam 40 is provided with attachment post 41, the length direction of attachment post 41 is vertical with the plate face of moved cross beam 40, the piston rod end of cylinder 50 arranges floating junction 51, floating junction and attachment post 41 are fastenedly connected, can eliminate assembly error like this, make cylinder smooth running.
Further, the cylinder body inflation of the piston rod external part of described cylinder 50, thereby pressure-acting lower piston makes progress, lifting is corresponding to the lifting action of top die B, the cylinder body venting of the piston rod external part of cylinder 50 is corresponding to the action of depressing of top die B, press machine top die B is reposefully when pressing down, the venting corresponding to cylinder body of cylinder 50, makes piston rod free-extension, and press machine is without providing extra power to overcome the power of cylinder 50 piston rods.
