. Antagonisms of high-speed machining for metalworking by pressure using a frame to the frame installed on it, which is set on a traverse in the form of traverses connected in dolonnes and connected to the front | receiver’s main line, in which there is a ram of a rod with a zafreshunnoy v / l of its traverse crosshead, a weight of our working tool, as well as returnable oil trays connected with the traverse beam.

- The purpose of the invention is to increase the machine's machine size.

For this purpose, in the proposed magawa, the preflash cylinders are located in the receiver's housing, while the underwater liners are connected to the air cavity of the receiver, and the overhead seals are connected to the pressure head.

Koestrukpi described mshpiva represented va drawing,

Manama consists of a bed 1, in which the Ba Amorg congestion 2 has a sub-frame installed, removed in the form of a receiver 3 "Traverse 4, strung columns 5., The cavity of the receiver is filled with high-pressure gas

pressure, and the lower part, liquid. The receiver has a rod 6, the piston-plunger 7 of which is made in the form of a golden plunger, the housing for which Serves: the receiver housing, 3 JB of the lower part of the receiver has a damper cavity 8. In the receiver 3, the cylinder 6 also has return cylinders 9 with return shaft 6 with traverse 1 O and a punch mounted thereon for separating the pipe, the rod cavities of the return cylinders being connected to the cavity of the receiver 3 filled with high-pressure gas. In cylinders 9 there are located piston rods 11 with pistons 12, and the effective area of the pistons, i.e. piston area without, taking into account rod spares, is larger than rod area 6 by I value, taking into account the forces of the weight of moving parts, friction force, etc. In the receiver case 3, in the holes connecting the Haji piston cavity with a cavity, The pressure, mounting rivet 13 and adjustable throttle 14. On iTpiaaepce 4 is placed stamp 15, in which the pipe 16 to be separated is locked. The machine works as follows.

In the drawing, left of the axis of symmetry, the machine is depicted at the moment when the process of the return of the rod 6 with the crosshead 1O to the top g is completed; In this position, the piston-plunger 7 interferes with the effect of the gas of the receiver - on the rod 6. The gas passes only through an adjustable throttle 14. adjusted so that the movement time of the rod b until the piston-plunger comes out of the spool cavity, i.e. before starting the process of acceleration of the rod with crosshead 10 and punch, more time is required to divert the rods 11 with pistons 12 to the lower position i Dd) cj of the gas compression process, which is located in 11OSTOST of the receiver 3, it is necessary to connect the piston cavities of the 9-diameter cylinders to the hydraulic line of the hydraulic drive , and the high pressure fluid, acting on the pistons 12, will move them to the lower position, compressing the cranks. Upon reaching such a position, the piston-plunger 7 leaves the spool cavity, and the high-pressure gas expands, accelerates the rod 6 with the crosshead 10 and the punch to high speed, providing the latter with the necessary Akinetic energy sufficient to separate the pipe 16 fixed in the die 1b. All the forces arising in this case are closed to the columns of the moving frame of the machine, and possible frame transitions are absorbed by shock absorbers 2. The remaining excess energy is quenched when the piston-plunger 7 enters the damper cavity 8 due to the work required to displace the fluid located in the damping cavity 8 through the gaps of the piston-plunger 7 and the cavity 8. From this condition, the height of the damping cavity is chosen. This prevents the stamp from being broken. All parts of the machine will occupy the position shown in the drawing to the right of the axis of symmetry.

To return the rod 6 from the cross-brace 1O to the upper position, it is sufficiently connected.

piston cavities of cylinders 9 with a drain line. Then, under the effect of gas pressure, found in receiver 3, due to the fact that the effective area of the pistons was; the area of the working rod 6, all CLEAN machines occupy the pinching, shown to the left of the axis of symmetry. The return time is determined only by the passage; The cross sections of the connecting piping, tm as a receiver, play the role of the EIK chamber and consequently constitute a fraction of a second. At the end of the stroke of the piston of the plunger 7, the valve cavity of the receiver performs the role of a damper cavity, and squeezing the fluid out of the closed volume of the arithmetic unit through the reverse 1 st valve 13 and the adjustable throttle 14.

In order to compress the gas in the cavity of the receiver 3 and make the next working stroke, it is necessary to connect the piston cavities of the cylinders 9 to the pressure reservoir, and the ttpouecc described above will be repeated again. During the movement of liiTOKo 11 downward, you can erronerate all the necessary auxiliary operators, since the working area of the machine is free from the working tool.
