Composite sharp-edge die cutting device for fluoroplastic sealing retainer ring and using method thereof

Abstract

The invention relates to a composite sharp-edge die cutting device for a fluoroplastic sealing retainer ring and a using method thereof. The composite sharp-edge die cutting device comprises a steel mold frame, a soft cushion arranged at the lower end of the steel mold frame and a soft cushion pre-tightening sleeve arranged at the periphery of the soft cushion, the device further comprises a die device, a positioning device and a die pressing device. The using method of the device comprises the following specific steps that S1, die matching is carried out; S2, assembly is carried out; S3, assembling is carried out; and S4, installation is carried out. According to the composite sharp-edge die cutting device, the ball guide column type steel mold frame is adopted, a female die and a male die are both made of composite sharp cutting edges, and both adopt the pre-compression type soft cushion to realize gapless cutting, and meanwhile, the floating type die pressing device is adopted, so that the situations that the gravity is pressed on a fluorine plastic plate, then the fluorine plastic plate is deformed, and the punch cutting precision is influenced are prevented; and the adverse problems of turning manufacturing of the fluorine plastic sealing retainer ring is solved by using the device, the machining precision requirement of the fluoroplastic sealing retainer ring is met, themanufacturing efficiency and the size precision control of the fluorine plastic sealing retainer ring are greatly improved, meanwhile, the assembling taper of the assembly is realized, and the assembly requirement is met.

Description

technical field [0001] The invention relates to the technical field of fluoroplastic production and processing, in particular to a composite sharp-edged die-cutting device for a fluoroplastic sealing back ring and a method for using the same. Background technique [0002] Due to its good high and low temperature resistance and self-lubricating properties, fluoroplastics are widely used in sealing retaining rings in hydraulic fluid structures. In industrial manufacturing, hydraulic fluid technology is an important component of execution and feedback in mechanical structures. Hydraulic seals It is an important link to ensure that the hydraulic performance and feedback meet the design requirements. In order to achieve high pressure and fast movement of the hydraulic fluid, the rubber sealing ring participating in the sealing must be protected in the hydraulic system to prevent the rubber sealing ring from being squeezed into the matching gap between the piston and the piston ba...

Problems solved by technology

[0003] Fluoroplastic molding can only be made into simple-shaped products such as plates, rods, casings, film blanks, and backing plates by a combination of cold pressing and sintering processing methods similar to "powder metallurgy". Fluoroplastic sealing retaining rings, fluoroplastic sealing retaining rings were originally manufactured by turning, resulting in the following defects: first, the utilization rate of raw materials can only be about 20%, and 80% of the materials are turned into waste; second, the turning efficiency is low ;Third, it is difficult to control the turning size, difficult to measure the size, and the scrap rate is high; Fourth, it is difficult to form a taper for assembly and loading due to the outer circle of the car, and it is difficult to assemble technical problems
