Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-7, a self-venting air hammer for die forging machining, comprising: an air hammer 1 with a hammer assembly 2; hammer assembly 2 includes: the hammer includes a hammer cylinder 21, a piston 22 provided in the hammer cylinder 21, a vent hole 23 opened in a side of the hammer cylinder 21, a conductive rod 24 provided in an end wall of the piston 22, a spring 25, and a hammer rod 26 provided in an end wall of the conductive rod 24. The surface of the hammering rod 26 is provided with a groove for accommodating the fixed component 4. The high-pressure airflow is input into the hammer barrel 21, the high-pressure airflow pushes the piston 22 to move, the piston 22 then pushes the conducting rod 24 to drive the hammering rod 26 to carry out hammering operation, after hammering is finished, the airflow is stopped to be conveyed, and gas is exhausted to the exhaust hole 23, the air pressure in the hammer barrel 21 is reduced to cause the pressure of the spring 25 to be reduced, the spring 25 resets to drive the bearing frame 3 to jack upwards, the bearing frame 3 jacks to drive the piston 22 and the conducting rod 24 to reset, the bearing frame 3 is arranged in the hammering assembly 2, and the fixing assembly 4 and the expanding assembly 5 are arranged in the bearing frame 3; the expansion component 5 includes: a screw sleeve 51, a screw rod 52, an expansion needle 53 and a regulating button 54; the threaded sleeve 51 is fixed with the bearing frame 3, the threaded sleeve 51 is in threaded connection with the screw 52, the two adjusting buttons 54 are connected with the expanding needle 53 through the screw 52, and the expanding needle 53 is clamped with the spring 25; make the knob 54 drive screw 52 through rotating the knob 54 and rotate the back, screw 52 then drives extension needle 53 and rotates, can make extension needle 53 expand the both sides of spring 25 and open, is convenient for insert the inside of spring 25 with fixed subassembly 4, and fixed subassembly 4 includes: the screw sleeve 41, the sharp head 42, the fixing frame 43, the liquid injection port 44 arranged on the surface wall of the sharp head 42 and the sliding chute 45 arranged on the side wall of the fixing frame 43; the chute 45 is movably connected with a liquid pipe 46, and a push rod 47 is arranged on the end wall of the liquid pipe 46.
