Description

DEVICE FOR DISTRIBUTION OF PIPES KOSCHES

The invention relates to the processing of metals by pressure, namely, the stamping of parts from pipe billets, and can be used in the aviation, shipbuilding or related industries.

A device is known for distributing pipe ends (RF patent No. 2122913, IPC V21D 41/02, 10.12.98), comprising a traverse configured to move along a rigidly fixed rod designed to accommodate a pipe billet and bearing a punch on the free end. At least two pipe blanks with a ring placed between them are coaxially located on the rod. The free space between the tube blanks is filled with a viscous mixture.

The disadvantage of this device is the low technological capabilities, because in the process of pushing the tube blanks onto the punch, pressure is created in the free space between the blanks and the wall of the outer tube blank that is not supported by anything from the outside can lose stability, which leads to poor quality of the manufactured products.

The closest in technical essence to the invention is a device for distributing pipe ends (RF patent No. 2122481, MNC V21D 41/02, 11.27.98). The known device contains a traverse made with the possibility of moving along a rigidly fixed rod, designed to accommodate a tube billet and bearing a punch at the free end. An additional cylinder is installed coaxially with the rod, connected to the traverse and equipped with holes with plugs for filling and draining the liquid in the cylinder, and a valve for

regulating fluid pressure inside it. At the free end of the punch there is a piston with an outer diameter equal to the extra diameter of the additional cylinder.

The disadvantage of this technical solution is the complexity of the manufacture of the device and the implementation of work on it, as it requires sophisticated hydraulic equipment and the use of a large number of technological operations to distribute the end of the pipe.

The invention is aimed at simplifying the crushing of devices and improving the quality of parts manufactured on it.

The supremacy of sampling is desired in the following. A device for distributing pipe ends, contains grass grass made with a 1-way-6-way-6 movement along a rigidly fixed, intended for placing a tube billet and carrying a punch at the free end. In contrast to the prototype, a casing is additionally attached to the traverse additionally 1. An elastic medium is located between the tubular billet and the inner wall of the casing, and a plug is made at the free end of the casing.

This embodiment of the device for distributing pipe sheaths makes it possible to create comprehensive hydrostatic pressure during deformation, both over the entire length of the workpiece and from its ends. And this, in turn, will prevent both loss of stability of the tube billet wall and its destruction along the end from the punch side. In addition, this device is easy to manufacture - it does not require the use of complex hydraulic systems and equipment that is difficult to manufacture.

The invention is illustrated by graphic materials, where FIG. 1 - shows a diagram of a device for distributing end pipes of the original SLAID, in FIG. 2 - to the same fe final FINDING.

the end of the puncheon 4. No traverse coaxially to the rod is rigidly fixed to the casing 5, on the free end of which is installed a plug 6. Inside the casing, a sleeve 7 made of elastic material.

The device operates as follows. The traverse 2, on which the casing 5 is rigidly mounted with an elastic medium 7 and a plug 6, is mixed; they are wound along the rod 1 to the initial position. A tube preform 3 is installed on the rod 1, then a punch 4 is installed on the free end of the rod 1. By moving the movable crosshead 2 with a force P, the tube preform 3 is pushed against the die 4. The part is formed from the tube preform under comprehensive hydrostatic pressure on the preform during it deformation. This prevents loss of stability of the wall of the tube billet and its destruction along the end, from the side of the punch, especially when distributing aluminum and titanium alloys, as well as stainless steels with a wall thickness of 0.5-1.5 mm.
