Description
Technical Field
The invention relates to the field of drawing dies, in particular to a manufacturing method of a high-radioactivity waste glass solidified body storage tank.
Background
Highly radioactive waste is typically treated by a glass curing process. Glass consolidation is the process of blending waste into a glass binder to form a consolidated body of glass. The glass solidification process includes concentrating and calcining the radioactive waste to convert the salt content into oxide, melting with glass base material and final casting into glass solidified body.
Storage containers for high level waste glass solidification bodies are often stored in tanks. In order to ensure high quality of can bodies for storing high level waste glass-solidified bodies, such can bodies are mainly manufactured by drawing. The drawing process draws the plate into a cylindrical shape with an open top, and then seals the top of the cylindrical structure by welding or the like, while the high level waste glass solidified body is placed in the tank body.
Drawing, also known as drawing and deep drawing, refers to the process of drawing a sheet material into a hollow part, and the wall thickness of the material is basically unchanged from the sheet material to the forming process. The drawing die is suitable for various industries, has wide practicability and is a common process in a stamping process. From blank to deep drawing forming, multi-step completion, primary deep drawing and secondary deep drawing … … forming are required.
Existing storage tanks for glass-solidified bodies of highly radioactive wastes are generally made using deep-drawing dies. In order to ensure the drawing quality, drawing is carried out for multiple times. However, the bottom of the male die used for each drawing in the existing drawing die protrudes outwards to form a spherical surface, so that the bottom of the can body is thinner and thinner as the bottom is drawn.
Meanwhile, the existing drawing die for producing the can body is shown in fig. 1, the punch assembly is shown in fig. 2, and the drawing die comprises a positioning block, a punch holder, an extension die and a punch which are sequentially connected through screws and share the same axis, and the top end and the bottom end of the positioning block are respectively inserted into the extension die and the punch. In the structure, because the maximum outer diameter of the part of the extension die and the male die cannot be larger than the outer diameter of the forming part on the male die, only an annular groove body can be processed on the side wall of the extension die, then a screw for connecting the extension die and the male die is prevented from being arranged in the groove body, and the tail end of the rod part of the screw penetrates through the extension die and then is in threaded connection with the male die. The radial size of the groove body cannot be overlarge due to the requirement of taking the strength of the extension die into consideration; and after the radial dimension of the groove body is limited, the installation space of the screw is limited, so that the screw can only be arranged by the edge of the male die as far as possible. When the screw is fixed at the edge of the male die and the radial direction of the groove body is limited, the screwing space of the screw is limited, so that the screwing work is very troublesome, and due to the limitation of the extension die, the screw cannot be screwed for one circle, and the screw can be screwed again and can be screwed for a large half circle by screwing the screw through a manual wrench. This way of fixing the screws results in that the tightening force of the screws is always insufficient and easily loosened.
