Hybrid driven punch

Abstract

The invention relates to a hybrid driven punch. A hydraulic oil cylinder and a mechanical connection rod mechanism are adopted and combined with each other. The hybrid driven punch comprises the hydraulic oil cylinder and a machine body. A piston rod is installed in the hydraulic oil cylinder. A slider is installed in the machine body and is connected with the piston rod through the connection rodmechanism. The innovation points lie in that the oil cylinder is adopted for driving two sets of symmetrically connected toggle rod mechanisms so as to achieve the purposes of secondary force increase and speed increase effects and adjustable working stroke and speed. The hybrid driven punch has the advantages that the slider is connected with the piston rod through a double toggle mechanism, thus the slider has the speed increase and force increase effects, thereby reaching the needed forge-press force in the mode that the hydraulic oil cylinder only needs to give small force to the double toggle mechanism, energy consumption is lowered greatly, energy is saved, and meanwhile the purpose of the adjustable stroke and speed of the slider can be achieved by controlling the stroke and speedof the hydraulic oil cylinder.

Description

technical field [0001] The invention relates to a hybrid drive stamping machine, in particular to the field of mechanical manufacturing. Background technique [0002] The traditional mechanical punch press usually adopts the slider crank mechanism. Although it has the characteristics of quick return and force amplification, it is difficult to obtain the ideal working stroke curve due to the limitation of the mechanical structure. The speed of the slider is not easy to change, and due to the limitation of the mechanical structure, the working The stroke is fixed and cannot be adjusted. And another type of molding equipment, the hydraulic press, although the stroke and speed can be adjusted, but because the hydraulic press is directly driven by the oil cylinder oil pump motor, the energy consumption is large, the efficiency is low, and the working frequency is difficult to increase. At the same time, the two types of equipment are limited by the structural arrangement, and th...

[0002] The traditional mechanical punch press usually adopts the slider crank mechanism. Although it has the characteristics of quick return and force amplification, it is difficult to obtain the ideal working stroke curve due to the limitation of the mechanical structure. The speed of the slider is not easy to change, and due to the limitation of the mechanical structure, the working The stroke is fixed and cannot be adjusted

The other kind of forming equipment, the hydraulic press, although the stroke and speed can be adjusted, but because the hydraulic press is directly driven by the cylinder oil pump motor, the energy consumption is large, the efficiency is low, and the working frequency is difficult to increase.

At the same time, the two types of equipment are limited by the structural layout restrictions, and the deflection of the beam, workbench and both sides of the fuselage is relatively large in the working state
