High-pressure common rail gasoline controllable internal combustion drive and steel wire belt return mode confronting forging hammer

Abstract

High-pressure common-rail gasoline controllable internal combustion drive and steel wire belt return method counter impact forging hammer, including two AC servo motors arranged symmetrically on the upper part. The extension shaft of the AC servo motor is connected with a steel belt reel. The steel belt wound and installed is connected to the upper hammer, and the upper hammer is connected to the first piston in the first internal combustion cylinder through the first hammer rod. The first fuel injector on the first internal combustion cylinder is the The first nozzle; the lower hammer is connected to the second piston in the second internal combustion cylinder through the second hammer rod, and the second fuel injection nozzle connected to the second internal combustion cylinder is the second nozzle on the high-pressure common rail system, The upper hammer and the lower hammer slide along the guide rail, and the counter-action internal combustion hammer and high-pressure common rail system are used to supply oil, which improves the work efficiency and greatly reduces the damage caused by vibration due to the suspended counter-impact, meeting the needs of various processes , The forced return method of the flexible steel belt avoids the energy loss caused by the back pressure return method of the traditional internal combustion hammer.

Description

technical field [0001] The invention belongs to the technical field of internal combustion hammers for forging and forming equipment, and in particular relates to a high-pressure common-rail gasoline controllable internal combustion drive and a steel wire belt return mode counter-impact forging hammer. Background technique [0002] The internal combustion hammer is a forging hammer that uses liquid or gaseous fuel as the main energy source. The commonly used fuels are gasoline, diesel, liquefied petroleum gas, etc. The internal combustion hammer has the characteristics of small size and light weight, and its energy is easy to adjust. It only needs to change the intake pressure. Different blow energy can be obtained according to the corresponding fuel injection quantity. The internal combustion hammer is widely used in profile blanking, die forging, precision die forging, powder forging, hot and cold extrusion and other processes. It can produce a variety of forgings and has ...

AI Technical Summary

Problems solved by technology

The internal combustion hammer is widely used in profile blanking, die forging, precision die forging, powder forging, hot and cold extrusion and other processes. It can produce a variety of forgings and has a high advantage in economy. This return method will cause some energy loss and due to the large impact energy, when the hammer body falls, it will generate a large vibration and cause the frame to jump up, which is prone to loose connection and is not conducive to mechanization of operation. These problems need further research and improvement
