Energy-saving combined air cylinder

Abstract

The invention relates to an air cylinder, in particular to an energy-saving combined air cylinder special for punching equipment. The energy-saving combined air cylinder comprises a large air cylinder, a small air cylinder and a piston rod clutch connection device. A large piston rod in the large air cylinder is a large hollow piston rod. A small piston rod in the small air cylinder penetrates through the large hollow piston rod. The piston rod clutch connection device comprises a built-in air cylinder, a radial groove formed in the small piston rod and a pin hole formed in the large hollow piston rod. The built-in air cylinder is arranged on a punching air inlet cavity of the large air cylinder, an air inlet cavity of the built-in air cylinder is communicated with the punching air inlet cavity of the large air cylinder, an air exhaust cavity of the built-in air cylinder is communicated with a center hole in the large hollow piston rod, and a piston pin rod in the built-in air cylinder is in sliding fit with the pin hole. By the adoption of the energy-saving combined air cylinder, set pressure is ensured, and air consumption amount is reduced. Compared with the prior art, the energy-saving combined air cylinder has the advantages of reducing air consumption amount exponentially, and being high in working speed.

Description

technical field [0001] The invention relates to an air cylinder, in particular to an energy-saving combined air cylinder specially used for stamping equipment. Background technique [0002] Cylinder, widely used in the transmission mechanism of mechanical equipment, replaces the moving parts and driving power of complex mechanical equipment, and is an essential component of automation equipment. Compared with the traditional electric mechanism, the energy consumption of the cylinder is several times larger. When designing mechanical equipment, engineers have to consider energy consumption, which makes it difficult to popularize large cylinders. [0003] At present, in order to simplify the manufacture of small stamping equipment, many enterprises at home and abroad have begun to use cylinders as power instead of complex motor stamping mechanisms. Although the equipment manufacturing cost is saved, the selling price of the equipment is reduced. However, the cylinder consum...

AI Technical Summary

Problems solved by technology

A double-force cylinder is produced (combined up and down with two or three cylinders), which increases the pressure, but does not change the problem of energy consumption

On the market (low energy consumption) gas-liquid booster cylinder, the gas-liquid booster cylinder is supplied by the air pump and the hydraulic pump at the same time. Although the gas consumption is reduced, the hydraulic pump consumes electricity and increases the supporting cost of the equipment.
