Abstract
The invention relates to a solid propellant pressure curing detection sample die tool. The die tool is composed of a die body part and an auxiliary part, the die body part is provided with an upper die, a middle die and a lower die, the upper die is provided with a gas inlet valve, a gas outlet valve and a pressure meter, the upper die, the middle die and the lower die are respectively provided with a locating hole, and the locating holes are provided with bolts and nuts to realize location. An assembly of the middle die and the lower die is used to accommodate a propellant paste, a sealing die body part formed by the upper die, the middle die and the lower die is used to inject nitrogen in order to realize pressurization, and oven curing, room temperature cooling, exhaust pressure relief and bolt releasing processes are carried out to obtain a solid propellant pressure curing detection sample. The solid propellant pressure curing detection sample die tool has the advantages of simple structure, convenience in operation, good pressure bearing safety, and realization of standard reaching of the sample.
Description
Technical field
The present invention relates to a kind of mechanical technology equipment, particularly a kind of solid propellant cure under pressure detection sample mould frock.
Background technology
Generally, the vacuum pouring powder charge process of solid propellant rocket can produce certain Residual stresses and strains, and then can affect the reliability of engine.The cure under pressure powder charge of solid propellant rocket has become as a new technology, studies carefully the impact to the performance of propellant for the cure under pressure charge process it is necessary to carry out experimental study to solid propellant cure under pressure detection sample for understanding.
Content of the invention
The invention aims to providing a kind of solid propellant cure under pressure to detect sample mould frock, it is capable of the technical process of effective simulation cure under pressure powder charge, and the inspection reliably preparing cure under pressure powder charge detects sample.
The technical scheme is that a kind of solid propellant cure under pressure of design detects sample mould frock, it is made up of die body component and accessory, wherein, die body component is provided with mould, middle mold and lower mould, intake valve, air outlet valve and pressure gauge are provided with upper mould, upper mould, middle mold and lower mould are respectively arranged with location hole, and location hole can configure screw bolt and nut to realize positioning.
The method have the benefit that: because upper mould, middle mold and lower mould are respectively arranged with location hole, location hole can configure screw bolt and nut to realize positioning, with the use of sealing ring, the die body component firm position of mould, middle mold and lower mould composition and sealing can be made tight.Simultaneously because being provided with intake valve, air outlet valve and pressure gauge on upper mould, thus pressurize sample preparation, pressure monitoring and pressure releasing process can be realized.Nitrogen can be connected additionally, due to intake valve and carry out sample preparation of pressurizeing, thus safe and reliable.The present invention also have the advantages that structure be simple and convenient to operate, pressure-bearing safety and sample up to standard.
Brief description
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
In figure, 1. die body component, 2. accessory, 3. go up mould, 4. middle mold, 5. descend mould, 6. intake valve, 7. air outlet valve, 8. pressure gauge, 9. location hole, 10. bolt, 11. nuts, 12. sealing rings.
Specific embodiment
The invention will be further described to divide two parts below by the embodiment that accompanying drawing provides.
Part I, structure member.
Described mold tooling includes: die body component (1), accessory (2)；
Die body component (1) includes: upper mould (3), middle mold (4), lower mould (5)；
Accessory (2) includes: intake valve (6), air outlet valve (7), pressure gauge (8), location hole (9), bolt (10), nut (11), sealing ring (12).
Part II, sample making course.
Lower mould (5), middle mold (4) configure successively, connect lower mould (5) and middle mold (4) with bolt (10) and nut (11), firm position, forms lower mould (5) and middle mold (4) sub-assembly.This sub-assembly is put in casting machine, irrigates solid-propellant pulps.Sealing ring (12) is added between upper mould (3) and middle mold (4), cooperation is firmly, connect positioning with bolt (10) and nut (11), form sealed reliable, the die body component (1) of firm position.The air outlet valve (7) of mould (3) is closed in pass, open the intake valve (6) of mould (3), connect and filling nitrogen, according to pressure gauge (8) indicating value, close intake valve (6) in good time, complete the pressure process of solid propellant sample powder column.Die body component (1) after pressurization is placed in solidification in baking oven.Solidification finishes, and room temperature cools down, and delays and outputs air valve (7), and removal pressure discharges bolt (10) and nut (11), takes off mould (3) and middle mold (4) successively, obtains cure under pressure detection sample.
Claims (1)
1. a kind of solid propellant cure under pressure detects sample mould frock, it is made up of die body component (1) and accessory (2), it is characterized in that: die body component (1) is provided with mould (3), middle mold (4) and lower mould (5), intake valve (6), air outlet valve (7) and pressure gauge (8) are provided with upper mould (3), upper mould (3), middle mold (4) and lower mould (5) are respectively arranged with location hole (9), and location hole (9) can configure bolt (10) and nut (11) to realize positioning.
