Abstract
An improvement structure for air hammer lever, comprises hammer stem, is contained in first piston ring, the second piston ring of hammer stem.Described hammer stem upper end is evenly laid with multiple the first air admission holes, be laid with multiple the first ventholes, and the first air admission hole is communicated with in hammer stem first groove corresponding thereto with the first venthole; Hammer stem lower end is equally evenly laid with multiple the second air admission holes, be laid with multiple the second ventholes, and the second air admission hole is communicated with in hammer stem second groove corresponding thereto with the second venthole.In the time that pneumatic hammer hits downwards, compressed air enters out to promote first piston ring from the first venthole again from the first air admission hole makes it be adjacent to casing wall sealing; In the time that pneumatic hammer is upwards mentioned, compressed air enters out to promote second piston ring from the second venthole again from the second air admission hole makes it be adjacent to casing wall sealing.The utility model, by the architecture advances of air hammer lever, makes piston ring and cylinder body reach good sealing effectiveness, greatly improves tup hitting power, has improved operating efficiency.
Description
Technical field
The utility model relates to forging machinery equipment, particularly relates to a kind of improvement structure of air hammer lever.
Background technology
To there is zanjon and large tripe in forging pneumatic hammer in use for some time cylinder body, find that by smoothing with after improving piston ring material the subsides power of piston ring and cylinder body is little, sealing decline, and air pressure deficiency, tup hits unable.
Utility model content
The technical problems to be solved in the utility model is that in order to overcome cylinder body, because sealing is poor, tup hits unable phenomenon, and a kind of improvement structure of air hammer lever is provided, and reaches good sealing effectiveness.Also can refer in new equipment processing simultaneously.
The technical scheme adopting is:
An improvement structure for air hammer lever, comprises hammer stem, is contained in first piston ring in hammer stem first groove, is contained in the second piston ring in hammer stem second groove.Described hammer stem upper end is evenly laid with multiple the first air admission holes, be laid with multiple the first ventholes, and the first air admission hole is communicated with in hammer stem first groove corresponding thereto with the first venthole; Hammer stem lower end is equally evenly laid with multiple the second air admission holes, be laid with multiple the second ventholes, and the second air admission hole is communicated with in hammer stem second groove corresponding thereto with the second venthole.In the time that hammer stem moves downward, compressed air enters out to promote first piston ring from the first venthole again from the first air admission hole makes it be adjacent to casing wall sealing; In the time that hammer stem moves upward, compressed air enters out to promote second piston ring from the second venthole again from the second air admission hole makes it be adjacent to casing wall sealing.
The utility model, by the architecture advances of air hammer lever, makes piston ring and cylinder body reach good sealing effectiveness, and tup hitting power improves greatly, thereby has improved operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
An improvement structure for air hammer lever, comprises hammer stem 1, is contained in first piston ring 3 in hammer stem first groove 2, is contained in the second piston ring 5 in hammer stem second groove 4.Described hammer stem 1 upper end is evenly drilled with six φ, 7 first air admission holes 6, be drilled with six φ, 7 first ventholes 7, and the first air admission hole 6 is communicated with in hammer stem first groove 2 corresponding thereto with the first venthole 7; Hammer stem 1 lower end is equally evenly drilled with six φ, 7 second air admission holes 8, be drilled with six φ, 7 second ventholes 9, and the second air admission hole 8 is communicated with in hammer stem second groove 4 corresponding thereto with the second venthole 9.In the time that hammer stem moves downward, compressed air enters out to promote first piston ring 3 from the first venthole 7 again from the first air admission hole 6 makes it be adjacent to casing wall sealing; In the time that hammer stem moves upward, compressed air enters out to promote second piston ring 5 from the second venthole 9 again from the second air admission hole 8 makes it be adjacent to casing wall sealing, forms a kind of improvement structure of air hammer lever.
Operation principle
In the time that pneumatic hammer hits downwards, air enters out to promote first piston ring 3 from the first venthole 7 again from the first air admission hole 6 makes it be adjacent to casing wall, realizes sealing effectiveness good while strike.In the time that pneumatic hammer is upwards mentioned, air enters and out promotes second piston ring 5 from the second venthole 9 again and make it be adjacent to casing wall from the second air admission hole 8, realizes sealing effectiveness good while carrying hammer.Because processing restriction the second air admission hole 8 can only drill through from above, thus also through hole above to be blocked with fluting flush end holding screw, in case leak-stopping gas.(as shown in Figure 1).
Claims (1)
1. the improvement structure of an air hammer lever, comprise hammer stem (1), be contained in first piston ring (3) in hammer stem first groove (2), be contained in the second piston ring (5) in hammer stem second groove (4), it is characterized in that described hammer stem (1) upper end is evenly laid with multiple the first air admission holes (6), in hammer stem first groove (2) corresponding thereto, be laid with multiple the first ventholes (7), and the first air admission hole (6) is communicated with the first venthole (7); Hammer stem (1) lower end is equally evenly laid with multiple the second air admission holes (8), in hammer stem second groove (4) corresponding thereto, is laid with multiple the second ventholes (9), and the second air admission hole (8) is communicated with the second venthole (9).
