Corrugated metal hose net cover pressing ring locking device and method

Abstract

The invention discloses a corrugated metal hose net cover pressing ring locking device and method. The corrugated metal hose net cover pressing ring locking device comprises a die handle which is fixedly connected to an upper die frame, wherein the upper die frame is fixedly connected to an upper die through a first guide column, a first elastic element is arranged between the upper die frame andthe upper die, and the outer side of the upper die frame is fixedly connected to the upper end of a taper wedge; the lower end slope of the taper wedge is matched with the outer side slope of the slide block, the inner side of the slide block is fixedly connected to a replaceable split die lower die, a limiting plate is fixedly connected above the slide block and the lower die, and the outer sideof the limiting plate is matched with the inner side of the taper wedge; the slide block is placed on a radial guide positioning device, and the outer side of the radial guide positioning device is matched with or fixedly connected to the inner side of a baffle plate; the upper portion of the inner side of the baffle plate is matched with the outer side of the lower end of the taper wedge, and a second elastic element and an end cover are sequentially arranged on the outer side of the baffle plate; a second guide column passes through the end cover and the baffle plate, and is fixedly connected to the slide block; existing end face shapes of the three parts can be changed by regulating and controlling plastic deformation, so that enough plastic deformation is obtained; the three parts aretightly attached, so that assembling consistency of the corrugated tube, the net cover and the net cover pressing ring is guaranteed, and the end sealing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of advanced material forming, and in particular relates to a compression ring locking device and method for a corrugated metal hose net sleeve. Background technique [0002] Corrugated metal hoses are mainly used for the transportation of various liquids and gases and the compensation of piping installation errors. The corrugated metal hoses are made of comprehensive metal materials that are resistant to high and low temperature, high pressure, corrosion, aging, wear, and are fully sealed without holes. properties, and the flexibility of the corrugated structure, the application range is very wide. For example, the transportation of clean gas in the semiconductor medical industry; the demand for high-temperature environments in the metallurgy and electric power industries; the transportation of acids and alkalis in the petrochemical industry; the application of extreme temperature difference resistance and m...

Problems solved by technology

However, the inner diameter of the external mold is greater than or equal to the outer diameter of the compression ring of the mesh sleeve, and when the compression ring of the mesh sleeve is initially deformed, there is no internal constraint, and the plastic deformation of the bellows, the mesh sleeve, and the compression ring of the mesh sleeve is insufficient, and the strength is insufficient. Insufficient, the effect of the head is not good; in addition, there is no internal restraint in the early stage, and the net sleeve and the net sleeve pressing ring tend to bend inward. When the internal mold of the overall mold is pressed in later, the net sleeve is easy to cause the net sleeve to not fold inward.

These all affect the effect of the head, and there are also quality risks in the next step of joint welding. In addition, the overall rigid mold has poor versatility and is not suitable for batch flexible production of bellows with different calibers.
