Description
Technical field
The utility model is related to a kind of fixture, especially a kind of for manufacturing LP types (right arch plain edition) rupture disk
Shaping jig.
Background technology
Rupture disk be demarcate burst pressure and at a temperature of explosion pressure release element, it is zero with clamper (or support ring) etc.
Part constitutes blasting piece device, and blasting piece device is the pressure relief device that can not repeat closure, is started by the static pressure of porch, is led to
The rupture by pressuring film plate is crossed come pressure of releasing.It is exactly briefly disposable pressure relief device, it is quick-fried at a temperature of the explosion of setting
When fragmentation pressure at both sides difference reaches predetermined value, rupture disk is actionable (being broken or coming off), and fluid of releasing out.
LP type rupture disks, are right arch plain edition rupture disk, and during work, system pressure acts on the concave surface of arch shell, when being protected
During protecting system superpressure, element is two-way to be stretched, and is plastically deformed, wall thickness reduction, final rupture, pressure of releasing, so as to play
The effect of protection system.
Such as Fig. 1, for the structure of the conventional brace of LP type explosion sheetmoldings, including upper fixture 04 and lower clamp 01, upper
Rupture disk to be processed 02 is placed between fixture 04 and lower clamp 01, pressure passage, LP are opened up in upper fixture 04 and lower clamp 01
The shaping of type rupture disk is to lean on to realize compressing and seal to compress blasting piece device to upper lower clamp applying pressure completely, is deposited
Deficiency be：
1) multiple explosion sheetmoldings to be processed, it is desirable to which fixture machining accuracy is very high, the machining accuracy of blasting piece device
Very high, existing forming process is necessarily required, even if being mounted with sealing ring 03, sealing is also difficult to ensure that under normal circumstances, caused
Pressure leakage and cause shaping fail；2) traditional tight rupture disk of whole face pressure, does not set blasting piece device positioning and upper lower clamp
Between positioning, it is pure to put alignment by hand by employee, lose time error-prone, can because caused by consistency from top to bottom error impression lack
Fall into maimed person's product.
The content of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of LP types rupture disk shaping jig, the folder
Tool can realize the shaping of various outer diameter model rupture disk, and accurate positioning is quick, can avoid because pressure leakage and caused by shaping
Fail and because of impression defect maimed person product problem caused by alignment error.
The utility model solve its technical problem use technical scheme be：Including the shaping upper fixture docked up and down and into
Type lower clamp, multiple compression modules are provided with the shaping upper fixture, and each compression module includes that vertical through holes and sealing are pacified
Piston depression bar in vertical through holes, is provided with porous pressing plate above all compression modules, and porous pressing plate is connected in shaping
Upper fixture upper surface and block compression module vertical through holes upper port, multiple intercommunicating pores, intercommunicating pore are set on porous pressing plate
Upper port connection compaction pressure source, the lower port of intercommunicating pore communicates with vertical through holes；The upper surface shape of the shaping lower clamp
Into there is molding space, rupture disk raw material plate to be formed is placed in molding space and passes through location-plate defined position each other, positioning
, just to compression module, in the central lower of each rupture disk raw material plate, molding space is all by pressure for rupture disk raw material plate afterwards
Pipeline is communicated to downwards briquetting pressure source；Also there is escape orifice in the inside of piston depression bar, a port of escape orifice is positioned at quick-fried
Molding space is led in the overcentre of fragmentation raw material plate, its another port in side.
Compared to existing technology, a kind of LP types rupture disk shaping jig of the present utility model, including in the shaping docked up and down
Fixture and shaping lower clamp, rupture disk raw material plate to be formed are placed on the molding space between shaping upper fixture and shaping lower clamp
It is interior, and by location-plate defined position each other, can be by changing various sizes of location-plate, so as to realize different model external diameter
The shaping of the rupture disk of size, positioning function is also relatively conventional to put time-consuming and not error-prone, and operating efficiency is carried significantly
It is high；The utility model is using the multiple compression modules in shaping upper fixture, from top respectively to the multiple in shaping lower clamp
Rupture disk raw material plate to be formed is compressed, while coordinating the briquetting pressure source below rupture disk raw material plate, and is carried out respectively
Shaping pressure, therefore each rupture disk raw material plate can be implemented individually to compress and be molded, relatively conventional whole face pressure is tightly quick-fried
Fragmentation, preferably solves and is molded failure because of pressure leakage caused by rupture disk pressure ring mismachining tolerance and fixture mismachining tolerance
Problem；Additionally, two positioning in the utility model fixture, the i.e. positioning of rupture disk raw material plate and shaping upper fixture, shaping
The Set and Positioning of lower clamp, effective restriction is all constituted in both horizontally and vertically two dimensions, be successfully avoid because of alignment
Impression defect maimed person product problem caused by error.
