Abstract
The utility model relates to a sealing sleeve of an air hammer lever, which consists of an upper pulley, lower pulley, a configuration pulley, balance weight pulleys, a balance weight, a compaction bolt hole, a convex compaction flange and sealing material. The upper pulley is arranged right above the sealing sleeve. The two lower pulleys are arranged at the two sides of the convex compaction flange. The two balance weight pulleys are arranged at the side parts of the lower pulleys under the configuration pulley. The balance weight is connected with the balance weight pulleys. The compaction bolt hole is connected with the convex compaction flange at the lower part through the sealing material. Compared with the prior art, the utility model automatically adjusts compaction sealing state through the balance weight. Sealing gap which is generated by abrasion is automatically compacted by a clump weight. The device is simple and practical. The replacement of stuffing is convenient. Little daily maintenance is needed.
Description
Technical field
The utility model relates to a kind of seal cartridge assembly, especially relates to a kind of sealing shroud of pneumatic hammer hammer stem.
Background technology
Its power source of main production equipments steam engine pneumatic hammer of flat-die forging industry is steam or compressed air at present, and its pressure is about 8 kilograms every square centimeter.By valve piston up and down reciprocatingly control moving up and down of its hammer stem of big piston, reach the purpose of forging and pressing.The sealing of manufacturer between design activity hammer stem and cylinder body fairlead all adopts wear-resistant seal ring and asbestos packing as airtight and watertight padding, and the method that compresses with convex ring flange and sealing bolt is fixed on the hammer body.But have now and exist many weak points, influence ordinary production and the very high maintenance cost of change expense.
Pumping during (1) owing to hammer stem work, airtight and watertight padding is is very easily worn and torn.If untimely adjustment bolt compresses, wearing clearance causes gas leakage, makes the pneumatic hammer can't operate as normal (per tour is less important to be adjusted several times).
Strenuous vibration and filler when (2) forging equipment is worked wear and tear gradually, cause the hold-down bolt of pretension to become flexible and generation gas leakage.
(3) forging and pressing work because the off-centre of hammer stem power drives supported flange dish on one side, causes monolateral stressed in case generation is beaten partially.Often break hold-down bolt, repairing can only stop production.
Summary of the invention
The purpose of this utility model is exactly the sealing shroud that the pneumatic hammer hammer stem that a kind of cost is lower, device is simple and practical is provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of sealing shroud of pneumatic hammer hammer stem, it is characterized in that, the sealing cover is by top sheave, lower sheave, the configuration pulley, the counterweight pulley, counterweight, the hold-down bolt hole, convex supported flange and encapsulant are formed, described top sheave has one, be located at the positive top of sealing shroud, described lower sheave has two, be located at the both sides of convex supported flange, described counterweight pulley has two, be located at the lower sheave sidepiece, described counterweight pulley is located at the bottom of configuration pulley, and described counterweight is connected with the counterweight pulley, and described hold-down bolt aperture encapsulant is connected with the convex supported flange of bottom.
Described top sheave, lower sheave, configuration pulley and counterweight pulley connect through steel wire rope.
Described hold-down bolt hole, encapsulant and convex supported flange vertically are provided with successively, and the centre is provided with hammer stem, and this hammer stem upper end is provided with piston.
Described hold-down bolt hole upside is provided with the gusseted point, and this gusseted point is connected through steel wire rope with the lower sheave in left side.
Compared with prior art, the utlity model has following advantage:
(1) utilizes counterweight to regulate automatically and compress sealing state;
(2) be flexible coupling by pulley, steel wire rope and supported flange between the connector, cut off focus and do not destroyed equipment;
(3) seal clearance of the normal wear of filler generation is tight from dynamic pressure by balancing weight, need not often to regulate hold-down bolt, the normal operating pressure of the equipment that guaranteed;
(4) solve the device damage that forges and presses inclined to one side forging of process hammer stem and cause, stopped to break the common phenomenon of hold-down bolt, reduced the repairing time, saved repair cost;
(5) device is simple and practical, and it is convenient to change filler, and the ordinary maintenance amount is little.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1 be top sheave, 2 for lower sheave, 3 for the configuration pulley, 4 for the counterweight pulley, 5 for steel wire rope, 6 for counterweight, 7 for the hold-down bolt hole, 8 for encapsulant, 9 for the convex supported flange, 10 for hammer stem, 11 for piston, 12 for the gusseted point.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of sealing shroud of pneumatic hammer hammer stem, its structure as shown in Figure 1, the sealing cover is made up of top sheave 1, lower sheave 2, configuration pulley 3, counterweight pulley 4, counterweight 6, hold-down bolt hole 7, encapsulant 8 and convex supported flange 9, top sheave 1 has one, be located at the positive top of sealing shroud, lower sheave 2 has two, be located at the left and right sides of convex supported flange 9, counterweight pulley 3 has two, level is located at the sidepiece of lower sheave 2, counterweight pulley 4 is located at the bottom of configuration pulley 3, and counterweight 6 is connected with counterweight pulley 4, connects by steel wire rope 5 between each pulley.Hold-down bolt hole 7 is connected with the convex supported flange 9 of bottom through encapsulant 8.Hold-down bolt hole 7, encapsulant 8 and convex supported flange 9 vertically are provided with successively, and the centre is provided with hammer stem 10, and the upper end of this hammer stem 10 is provided with piston 11.The upside in hold-down bolt hole 7 is provided with gusseted point 12, and this gusseted point 12 is connected through steel wire rope 5 with the lower sheave 2 in left side, and fixedly lower sheave 2.
When using this sealing shroud, when encapsulant 8 wearing and tearing, drive the convex supported flanges 9 automatic means of press seals material 8 that freely makes progress and contact, keep air tight with hammer stem 10 by counterweight 6.When forging and pressing take place to beat partially, drive the impact strength that counterweight 6 is beaten partially to the cushioning balance that comes up through convex supported flange 9.When recovering just often, counterweight 6 freely falls and encapsulant 8 is tending towards compressing sealing state forever.When changing encapsulant 8, the counterweight of slinging 6 freely falls convex supported flange 9, puts into new encapsulant 8, puts down counterweight 6 then and gets final product easy maintenance and installation.
