Изобретение относитс к куз ечно- ресеовому оборудованию, в частности, к кош трзпкаии высокоскоростных молотов.The invention relates to forging equipment, in particular, to high-speed hammer hammers.

Швестен привод высокоскоростного молота, содержащий газовую камеру, соединенную с источником эиергоноситеп , шток бабы, расположенный в газовой камере, и узел уплотн га , размещенный соосно штоку, при этом последний выполнен с коническим торцом, а узел уплотнени вьп1олнен в веде закрепленной на крьпшсе газовой камеры нажимной втулки и размешенного в ией вкладьппа с коническим отверстием, сопр женньпм с коническим торцом штока 11.The high-speed hammer drive contains a gas chamber connected to a source of air-boron, a rod of a woman located in a gas chamber, and a seal assembly located coaxially with a rod, while the latter is made with a conical end, and the seal assembly is filled in a slot attached to the gas chamber a push bushing and a liner placed in a bevel with a tapered bore, compatible with the tapered end of the rod 11.

Недостатком известного привода высокоскоростного молота вл етс недостаточна его надежность ввиду неравномерного износа вклафпиа .A disadvantage of the known high-speed hammer drive is its lack of reliability due to uneven wear of the valve.

Цель изобретени - повышение надежности.The purpose of the invention is to increase reliability.

С этьй целью привод высокоскоростного молота, содержаший газовую камеру, соединеииую с источником энергоносител , шток бабы, расположенный в газовой камере, и For this purpose, a high-speed hammer drive containing a gas chamber connected to an energy carrier source, a stock of a woman located in the gas chamber, and

узел уплотнени , размещенный соосно штоку, при этом последний выполнен с коническим торцом, а узел уплотнени вьшолнеи в виде закрепленной на крышке газовой камеры нажимной втулки и размещенного в ней вкладыша с коническим отверстием, сопр женным с коническим торцом штока, снабжен охватьь вающей вкладыш обечайкой, смоит рованной в нажимной втулке с возможностью самоуста овки .the seal assembly placed coaxially with the rod, the latter being made with a conical end, and the seal assembly being in the form of a pressure sleeve fixed on the gas chamber lid and an insert placed therein with a conical hole, fitted with a conical end of the stem, is equipped with a shell on the sleeve, simulated in a push bushing with the possibility of self-alignment.

На чертеже показан привод высокоскоростного молота, общий вид.The drawing shows the drive high-speed hammer, General view.

Привод состоит из рамы 1, расположешюй в ней газовой камеры 2, штока 3с коиичес15 ким торцом, бабы 4, расположенной в газовой камере 2, и узел уплотнени .The drive consists of a frame 1, a gas chamber 2 located in it, a rod 3 with a copper end, a female 4 located in the gas chamber 2, and a seal assembly.

Газова камера 2 соединена с историком энергоносител . Gas chamber 2 is connected to the historian of energy.

Claims

The seal assembly is made in the form of a pressure chamber 2 of the pressure sleeve b fixed on the lid 5 of the gas chamber 2, a liner 7 with a tapered bore and a shell 8 around the liner 7 is located in it. push sleeve 6 with a radial clearance, providing self-installation. In the insert 7 there are holes, through which the bolts 9 are passed for fastening the pressure sleeve 6 and the insert 7 is pressed against the cover 5. The insert 7 is made of a thermoplastic material. Drive high-speed hammer works as follows. In the upper position of the boom 4 with the stem 3 between its end, the lid 5 and the liner 7, a cavity 10 is formed, which is connected to the gas chamber 2 through a non-return valve 11, and connected by means of a pipeline 12 to a control valve 13 connected at this moment to the atmosphere . Baba 4 with stem 3 is held in the upper position due to the force generated by the gas acting on the collet 14 of the stem 3. To produce an impact, the cavity 10 through the distribution valve 13 is connected to the gas chamber

2. The force acting on the end of the stem 3 becomes, in this case, greater than the force of the gas chamber acting on the collar 14 from below, and the woman 4 with the stem 3 rushes down, striking the workpiece. | - After striking a woman by 4 shshindry 15 lifting rises. The rod 3 of the female 4, the inlet to the inlet, squeezes out a part of the gas found in the cavity 10 through the non-return valve 11 into the gas chamber 2, and its rest is then discharged through the distribution valve 13 to the atmosphere. After the cavity 10 is connected to the atmosphere, the woman 4 with the rod 3 due to the pressure of the gas perceived by the collar 14 pushes even more effort to the liner 7, and the woman does not need to be held by the lifting cylinders 15. The rods of the lifting cylinders are lowered and the hammer ready to produce the next strike. With such an execution of the drive, when assembling it, it is possible to ensure a consistent arrangement of the insert 7 and the end of the rod 3 of the female 4, which is achieved by the final tightening of the insert 7 while the rod 3 of the female 4 is in the upper position. The technical and economic effect of the invention is provided by increasing reliability. Claims of the Invention A high-speed hammer drive comprising a gas chamber connected to a source of energy carrier, a rod of a woman located in a gas chamber and a seal assembly placed coaxially with the rod, the latter being completed with a conical end face, and the seal assembly being designed in the form of a gas chamber fixed on the roof. push bushing and Raz; Meshch1ogo liner in it with a conical bore, mated with a conical end of the rod, characterized in that, in order to improve reliability, it is equipped with a shell enclosing the contour, When this latter is mounted in the sleeve, with nazhiyioy samourtanovki.
