Cylinder-mounted toggle-lever two-stage booster press

Abstract

The invention discloses a toggle-lever two-stage power-increasing press machine with a cylinder under it, wherein the cylinder is placed under the workbench, and a two-stage power-increasing mechanism connected in series by the toggle-lever is adopted, so that the press retains the traditional While the advantages of the pneumatic press, it can obtain a large output force, which is convenient for the forming and processing of the workpiece; at the same time, the lower position of the cylinder improves the stress condition of the press base, making it easier for the press base to meet the strength and rigidity requirements. It is beneficial to shock absorption and noise reduction, and also lowers the center of gravity of the press, thereby improving the dynamic performance of the press. Compared with the structure in the prior art, the structure size of the press machine can be greatly reduced, the impact force is large, the work efficiency is high, the energy utilization rate is high, the work noise is small, and it has superior comprehensive performance. It can be widely used in cutting, In processes such as punching, blanking, bending, riveting and shallow drawing.

Description

technical field [0001] The invention relates to an under-cylinder toggle-lever two-stage booster press. Background technique [0002] Pneumatic press is a kind of pressure processing equipment that uses air as the working medium to shape the billet. It is widely used in punching, bending, stretching and extrusion processes, and can directly produce finished or semi-finished products. However, the pneumatically driven press has a significant disadvantage, that is, the working pressure of the press is low due to the easy leakage of gas, usually only 0.4-0.7MPa, which cannot meet the occasions requiring large output force. In the prior art, the power system of the pneumatic press is generally placed on the top, that is, the power system is placed above the worktable to drive the punch to move up and down for stamping. Some pneumatic presses are not symmetrical in structure, which will cause the center of gravity of the press to On the high side, the mechanical properties of th...

However, the pneumatically driven press has a significant disadvantage, that is, the working pressure of the press is low due to the easy leakage of gas, usually only 0.4-0.7MPa, which cannot meet the occasions requiring large output force

In the prior art, the power system of the pneumatic press is generally placed on the top, that is, the power system is placed above the worktable to drive the punch to move up and down for stamping. Some pneumatic presses are not symmetrical in structure, which will cause the center of gravity of the press to On the high side, the mechanical properties of the press are poor and the stability is poor

In addition, when the press is working, its impact force acts on the workbench, so that the workbench and the base need to bear a large impact force, resulting in greater noise. At the same time, this also requires the base of the press to have higher strength and rigidity. Therefore, to a certain extent, the overall size of the press is too large
