Embodiment Construction

[0023] The specific embodiment of the present invention will be further described in conjunction with accompanying drawing now:

[0024] Special process mold for processing Ω ring sealing gasket: such as Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the special process mold for processing Ω-ring sealing gaskets: the mold structure includes a second-order circular platform, bolts and pressure plates. The height of the table is 7mm, the diameter of the boss is 3-15μm smaller than the actual size of the inner diameter of the Ω ring sealing gasket, four bolt holes are evenly distributed on the boss, and the diameter is M12-20; the pressure plate is rectangular, and the end of the presser foot is a pointed circle Angle, slope shape, there are holes in the pressure plate, the diameter is slightly larger than the diameter of the bolt. The mold material is steel plate.

Abstract

The invention provides a specialized process mold for machining a pi-ring sealing washer and a manufacturing and use method, wherein the mold and the method belong to the field of heat exchanger sealing inner member processing. The process mold ensures processing precision of the pi-ring sealing washer. The specialized process mold comprises a two-step frustum, bolts and a pressure plate. The thickness of the base plate of the two-step frustum is not less than 60mm. The outer diameter of the base plate of the two-step frustum is larger than the designed diameter of the pi-ring sealing washer.The height of a boss is 7mm. The diameter of the boss is smaller than the actual dimension of the inner diameter of the pi-ring sealing washer by 3-15 [mu]m. Four bolt holes are uniformly distributedon the boss. The pressure plate is rectangular. The pressure feed end is a slope-shaped fillet. The pressure plate is internally provided with a hole. The mold is made of a steel plate. In machining of the pi-ring sealing washer, rough machining is performed on two planes, an inner circle and an external circle; then the pi-ring sealing gasket 1 is embedded into the process mold and is fixed by compressing screws 2 and the pressure plate 3; Semi-fine machining or fine machining is performed on the inner part and the outer part of the pi-ring. The specialized process mold and the manufacturingand use method have advantages of realizing simple manufacture and easy operation, ensuring machining of the qualified pi-ring sealing washer, effectively shortening production period and improving productivity.

Description

technical field [0001] The invention belongs to the field of heat exchanger sealing internal parts processing, and in particular relates to a processing tool for sealing gaskets. Background technique [0002] The Ω-ring sealing gasket is an important component of the Ω-ring heat exchanger. This component has a large diameter and a thin thickness. Its material is usually stainless steel, which is characterized by low carbon content, high toughness, poor plasticity, and high expansion coefficient, which makes processing difficult. Existing technology and equipment cannot solve the deformation and precision problems in the process of processing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a special tooling for processing Ω-ring sealing gaskets that ensures precision and does not deform, and its manufacturing and using methods. [0004] Special process mold for processing Ω ring sealing gasket: the mold str...
