Description
Technical Field
The invention relates to the technical field of metal part forming processes, in particular to a blank positioning device and a vacuum isothermal forging blank positioning system using the same.
Background
The vacuum isothermal forging is a forging process which heats a die to the blank deformation temperature and deforms at a low strain rate in a vacuum environment, so that the deformation resistance and the flow resistance in the forging process are reduced, and the problem of oxidation of the die and the blank is solved. The forging piece forged in a vacuum isothermal manner comprises materials such as aluminum alloy, titanium alloy, high-temperature alloy and high-strength steel, is widely used for manufacturing important structural parts such as an aircraft engine turbine disc in the aerospace field, and the forged product has excellent structure performance.
The vacuum isothermal forging process, including the shape, size and position of the blank, is precisely designed by simulation software. In actual production, the change of the placement position of the blank can cause abnormal conditions that the stress distribution of the forge piece is not expected, the forge piece is folded, a die cannot be completely filled and the like. Only when the blank is placed accurately, the accuracy of process execution can be ensured, and the forged piece with expected quality is obtained. Inaccurate blank position can also lead to the position of the die part being stressed too much and the pressure head of the press being stressed unevenly, which affects the service life of the equipment. Most of products produced by vacuum isothermal forging equipment are high-value products, blank materials and dies are expensive, and forging precision must be ensured. The vacuum isothermal forging equipment for automatic continuous production has higher requirement on the control of the position of a blank because the equipment cannot be operated by human interference frequently.
The position of the blank forged at the vacuum isothermal temperature is generally calculated by servo motor data in the process of loading by a manipulator at present. The servo motor has high precision and can accurately describe the position information of the mechanical arm with multiple degrees of freedom, but the mechanical arm works alternately in a high-temperature area and a low-temperature area, so that different temperatures can influence the size and shape of the mechanical arm and the clamp. When the manipulator clamps the blank, the gravity of the blank can also make the clamp and the mechanical arm generate micro deformation, and the deformation is related to various factors such as clamping position, blank weight, mechanical arm extension length, mechanical arm position temperature and the like, so that quantitative calculation is difficult. The two factors can cause inaccuracy in the position of the blank calculated from the servo motor data. When the manipulator moves to a target position, the upper ejection rod and the lower ejection rod of the press machine can clamp the blank, and in the clamping operation, if the upper surface and the lower surface of the blank have certain angles with the ejection rods, the clamping operation can also cause the change of the position of the blank. Therefore, the placing position of the blank cannot be accurately judged only through the manipulator, and other auxiliary measuring means need to be developed to ensure the accurate position of the blank in the vacuum isothermal forging chamber.
The forging chamber for vacuum isothermal forging is of a fully closed structure, works at a vacuum high temperature condition of more than 1100 ℃ for a long time, is internally provided with a water-cooling pressure head, a die seat, dies and heating equipment, is complex in structure, has a short distance between the upper die and the lower die, and has a narrow blank observation angle. The device capable of accurately measuring the position of the blank is suitable for measurement in a forging chamber under a vacuum environment and a high-temperature condition, and is an urgent need of vacuum isothermal forging equipment.
The development of a position measuring device suitable for vacuum isothermal forging blanks needs to overcome application difficulties, specifically: the position measuring components can only work at a lower temperature generally, and a heating system of the forging chamber continuously heats the inside of the forging chamber through heat radiation of a heating belt or an induction heating coil, wherein the temperature of the inside of the forging chamber can reach more than 1100 ℃.
