Quenching treatment clamp

Abstract

The invention relates to the technical field of heat treatment deformation prevention, in particular to a quenching treatment clamp. The quenching treatment clamp comprises exhaust pipelines, telescopic pipes, movable plug pins, an external pressure steel belt, a hoisting structure, a double-layer frame, a bottom plate, spherical surface inner supports, locking nuts and adjusting lead screws. Whena product is subjected to solid solution quenching, air in a closed cavity needs to be rapidly exhausted, rapid water entry of the product is guaranteed, thermal stress concentration caused by the temperature difference of different positions of the product due to slow exhaust is reduced, and the product can rapidly enter water through the design. Due to the fact that the diameter of the productis too large and the wall thickness is small, an inner support anti-deformation structure is designed, in other words, adjustable ejector blocks are evenly distributed in the circumferential directionof the product, constraint of variable radial forming force in the heat treatment process of the product is guaranteed, deformation in the quenching process is reduced, then the overall size of a boxbottom is controlled, and the purposes of reducing machining procedures and guaranteeing the product quality consistency are achieved; and the gap at home is made up, and therefore the device is highin practical performance and suitable for large-scale application and popularization.

Problems solved by technology

[0002] The overall spinning forming technology can realize the integrated forming of the bottom of the box, reduce the processing procedures, and ensure the consistency of product quality. Since the 2219 aluminum alloy used for product forming is a typical heat treatment-strengthened alloy, the solution quenching process in the heat treatment process involves the product. The process of short-term cooling at high temperature can easily cause deformation of the product due to thermal stress. At present, there is no complete set of anti-deformation fixtures for 2219 aluminum alloy integral spinning box bottom quenching treatment in China.
