Band sawing machine with hydraulic system controlled by rubber bag accumulator

Abstract

The invention discloses a gig saw controlling a hydraulic system by a bladder-type accumulator. The gig saw comprises a gasoline tank, a vane variable pump, a motor, a bladder-type accumulator,, a solenoid valve, a lifting hydro cylinder. The gig saw is characterized in that the vane variable pump and the motor connected with the gasoline tank are connected with the bladder-type accumulator, and then are sequentially connected with the solenoid valve. One side of the solenoid valve is connected with the lifting hydro cylinder and the other side is connected the gasoline tank, thus forming a complete loop. The vane variable pump and the motor store the energy of the bladder-type accumulator. Then the bladder-typed accumulator emitts the energy slowly to maintain the work of the entire loop in the course of the whole work, thus greatly reducing the usage of the motor, retarding the circulation of the hydraulic oil, lowering the oil temperature, prolonging the service life of the hydraulic components, and reducing stroke error. By actual test, the gig saw reduces the energy consumption by about 90 percent.

Description

1. Technical field [0001] The invention relates to a band sawing machine using a bladder type accumulator to control a hydraulic system, and relates to the technical field of design and manufacture of a band sawing machine for metal cutting. 2. Background technology [0002] my country's sawing machine industry has developed since the 1960s, gradually developing from the earliest bow sawing machine to the later band sawing machine, moving towards high speed and high efficiency. After entering the 21st century, the modern manufacturing industry is developing towards the direction of low energy consumption, high precision and high efficiency, which also poses a great challenge to our band sawing machine industry. How to balance energy consumption, precision and efficiency has become the first major problem. In the current domestic and international markets, most band sawing machines manufactured by manufacturers use hydraulic systems to control sawing. For the sawing of some...

AI Technical Summary

Problems solved by technology

For the sawing of some large materials, it often takes several hours or even dozens of hours, which leads to the long-term continuous operation of the large sawing machine, which increases the temperature of the entire oil circuit, resulting in a thin oil film and increased stroke error. At the same time, it also shortens the service life of hydraulic components and consumes a lot of energy
