Description

Blank positioning system and blank positioning device for vacuum isothermal forging

technical field

The invention relates to the technical field of metal part forming technology, in particular to a blank positioning device and a vacuum isothermal forging blank positioning system using the blank positioning device.

Background technique

Vacuum isothermal forging refers to a forging process in which the mold is heated to the deformation temperature of the blank in a vacuum environment and deformed at a lower strain rate, which reduces the deformation resistance and flow resistance of the forging process, and solves the oxidation of the mold and the blank. question. Vacuum isothermal forging forgings include aluminum alloys, titanium alloys, high-temperature alloys, high-strength steels and other materials, which are widely used in the manufacture of important structural parts such as aero-engine turbine disks in the aerospace field. The forged products have excellent microstructure and properties.

The vacuum isothermal forging process, including the shape, size and position of the billet, is precisely designed through simulation software. Changes in the placement position of the blank in actual production will lead to abnormal conditions such as the stress distribution of the forging not meeting expectations, folding of the forging, and inability to completely fill the mold. Accurate execution of the process and forgings of the expected quality can only be ensured if the billets are placed precisely. The inaccurate position of the blank will also lead to excessive force on the part of the mold and uneven force on the pressure head of the press, which will affect the service life of the equipment. Vacuum isothermal forging equipment produces mostly high-value products, and blank materials and molds are expensive, so forging accuracy must be ensured. Vacuum isothermal forging equipment for automatic continuous production, because it cannot often be operated by human intervention, has higher requirements for the control of the position of the blank.

At present, the position of the blank for vacuum isothermal forging is generally estimated by the data of the servo motor during the feeding process of the manipulator. The servo motor has high precision and can accurately describe the position information of the manipulator with multiple degrees of freedom. However, since the manipulator works alternately in high-temperature and low-temperature areas, different temperatures will affect the size and shape of the manipulator and clamp. When the manipulator clamps the blank, the gravity of the blank will also cause a small deformation of the clamp and the mechanical arm, and such deformation is related to various factors such as the clamping position, the weight of the blank, the extension length of the mechanical arm, and the temperature of each position of the mechanical arm. Difficult to quantify. The above two types of factors will lead to the inaccuracy of the billet position calculated by the servo motor data. When the manipulator moves to the target position, the upper and lower ejector rods of the press will clamp the billet. During the clamping operation, if the upper and lower surfaces of the billet and the ejector rod have a certain angle, the clamping operation will also cause the position of the billet to change. Therefore, the position of the billet cannot be accurately judged only by the manipulator, and other auxiliary measurement methods need to be developed to ensure the accurate position of the billet in the vacuum isothermal forging forging chamber.

The forging chamber of vacuum isothermal forging is a fully enclosed structure. It works under the condition of vacuum and high temperature above 1100°C for a long time. There are water-cooled indenters, mold seats, molds, and heating equipment inside. The structure is complex, and the distance between the upper and lower molds is relatively short. The viewing angle of the blank is narrow. It is an urgent need for vacuum isothermal forging equipment to develop a device that can accurately measure the position of the billet, and is suitable for measurement under high temperature conditions in a vacuum environment in the forging chamber.

The development of a position measuring device suitable for vacuum isothermal forging blanks needs to overcome application difficulties, specifically: position measuring components generally can only work at lower temperatures, and the heating system of the forging chamber is heated by thermal radiation or induction of the heating belt The coil continuously heats the interior, and the internal temperature can reach more than 1100°C.
