Forging hammer which is provided with anvil block and works in direct injection type gasoline internal combustion driving and flexible steel wire belt returning manner

Abstract

A forging hammer which is provided with an anvil block and works in a direct injection type gasoline internal combustion driving and flexible steel wire belt returning manner comprises two alternating-current servo motors which are symmetrically arranged. The alternating-current servo motors are connected with a machine body supporting column through a machine body support. Guide rails matched with an upper hammer are fixed to a stand column of the machine body supporting column. A shock absorber is installed between the machine body supporting column and a machine body base. Steel belt coiling blocks are connected to output shafts of the alternating-current servo motors. The other end of a steel belt is fixed to a hammer head. The hammer head is connected with a piston in an internal combustion cylinder barrel through a hammer rod. The steel belt drives the hammer head to forcibly return to a work starting point under the traction of the alternating-current servo motors. When a working cycle starts, an air inflow valve on the internal combustion cylinder barrel is opened, and compressed air is led in; then, atomized gasoline is led in by opening an oil spraying nozzle, and gas generated after particles of the atomized gasoline and the compressed air are mixed chemically react after being ignited through a sparking plug; a hammer rod and the hammer head are pushed by a piston to complete one time of worm hammering; energy loss caused by the backpressure returning is avoided; and meanwhile vibration of a foundation is reduced.

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 an anvil forging hammer with direct injection gasoline internal combustion drive and flexible steel wire belt return mode. 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 cutting, die forging, precision die forging, powder forging, hot and cold extrusion and other processes. It can produce a variety of forgings and has high economic advan...

AI Technical Summary

Problems solved by technology

The internal combustion hammer is widely used in profile cutting, die forging, precision die forging, powder forging, hot and cold extrusion and other processes. It can produce a variety of forgings and has high economic advantages. When it falls, it will generate a large vibration and cause the frame to jump up, and it is easy to loose the connection, which is not conducive to the mechanization of operation. In addition, due to the back pressure return method, it will cause some shortcomings such as energy loss. These all need further research and improvement.
