SU495200A1 - Pneumatic gun for driving nails - Google Patents

Description

the working pressure in the housing 11 is installed washer 16.

The safety device consists of a spring hammer 17, the sear of which enters the groove to the bracket 9 and interacts with its outlet 18.

The pneumatic hammer for nailing works in the following way.

Compressed air and spinning in handle 5 through channel b, and then throttling channel e, pressing the ball 15 to the saddle orifices and thereby locking the cavity of the diameter of the differential piston 12. Last, shuffle, or to the extreme (normal) position, by valve zairaet channel b. At the same time, the zyoolshnevaya iolost B of the working cylinder through channels c, z, 3, and is connected with the atmosphere.

After iodachi a nail into the barrel of a pneumatic pistol by any known method (hose, from the shop or leita), wipe the pistol with the barrel to the place where the nail should be driven, pull the trigger 17, pull the output from the groove to the bracket 9, and onto the handle 5. In this case, the body 4 of the intersection. 1, is relative to the working cylinder 1, the valve 6 is abutted by the ball 15 into the bracket 9 and opens the hole w. Due to a sharp drop in pressure in the cavity of a large diameter of the differential piston 12, the latter is transferred by working pressure to the extreme (left) position. The air flow through the channels s, g passes into the piston cavity B and abruptly throws the piston 2 with a striker, making a blow to the nail. With some time delay due to the throttling properties of the channel and the air passes into the interfacing cavity. The pressure reaches the maximum value in the piston stroke of the piston stroke (the moment of nailing) and the hand pressure is removed, which allows the body and the handle to be moved to the rearmost position. Thus, the valve 6 retracts from the bracket: a 9. Return the ball 15 to its original position , the piston 18 occupies the extreme (right) position, blocking the channel b and connecting the outer piston cavity with the atmosphere through the channels c, d, i, h. The porsun 2 is returned to its original position by the action of the spring 3. Odiotime, with delay due to the throttling effect of pressure

in a closed cavity. The pressure of the arm overcomes the resistance, and again the iosast body moves forward to the valve valve 6 in the bracket 9, as a result of which the cycle repeats. This will ensure automatic myoimpact operation of the pneumatic gun, 1ta, which allows you to hammer in nails 60-90 mm long in 3-

4 hits. The end of driving is determined by

the nature of the sound.

The introduction of a multi-shock allows the weight of the striker and the pistol to be reduced and reduces the recoil to almost impudent.

Ф орм ул а and 3 о б р е e and u

Pneumatic gun for nailing, containing a working cylinder, inside which is placed a piston with a striker, and an engaging working cylinder, movable and spring loaded in an axially aligned body with a handle in which a valve is located

1; the pistol is put into operation after pressing the handle and the handle, so that, in order to enable automatic hammering of nails of different lengths, in the case between its rear end and the end of the working cylinder is formed closed the cavity is connected to the throttling channel with the piston cavity; the working cylinder is provided with a valve interacting with the valve when pressing the handle and the arm with a preservative in the form of a spring-loaded trigger with a sear.
