Problems solved by technology

The existing propellant powder compression stretching method has the following problems: (1) the existing empirical data is used in the design process, and the test data of this time cannot be used. If the design result is not suitable, real-time correction cannot be carried out; (2) the design The process, manufacturing process, and testing process are independent links, which cannot be organically combined and fed back in a loop; (3) The detection value of the drug shape and size cannot be fed back in real time, and the detection value of the drug shape cannot be used for correction calculation

Embodiment Construction

[0039] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] Take the triple base propellant as an example.

[0041] Proceed as follows:

[0042] (1) The design of process parameters is completed by drug shape parameter design software 1, compression stretching process design software 2, and mold design software 3: number of holes = 19; pressure = 8MPa; drug discharge speed = 25mm / s; arc thickness = 1.9mm ;outer diameter=19mm;

[0043] (2) Push the process parameters to the collaborative platform 11 for propellant compression-stretching molding through the digital design management software 4;

[0044] (3) The cooperative platform 11 for propellant compression-stretching molding decomposes the process parameters by designing a multi-parameter measurement system 10 and a design control system 8. One part is the control parameter of the compression-stretching machine: press...

Abstract

The invention discloses a gun propellant companding moulding method which can achieve process design, parameter push and parameter measurement cycle operation, and conduct real-time inverse calculation of design data to obtain suitable companding process parameters. The method uses a collaborative platform technology, and achieves process design, parameter push, reading and analyzing of parameter measurement results, and process cycle operation. Compared with the existing technology, the parametric real-time circulation of design, companding and detection links is achieved, and the foundation is provided for synchronous correction feedback; the technology of target parameter and detection parameter data real-time contrast is used to achieve real-time judgment on the dimension parameters of gun propellant products. Compared with the existing technology, the quality criteria of product online parameters can be provided in real time.

Description

technical field [0001] The invention relates to a compression-stretching forming method of propellant, which is suitable for the compression-stretching process of propellant. Background technique [0002] The process of propellant product preparation includes absorption, water displacement, granulation, gelatinization, compression stretching, drying, etc. Among them, the compression stretching process is the forming process of propellant powder, and the dimensional accuracy, compactness, and surface gloss of propellant powder are uniform. It is determined by the quality of the compression-stretching process, and the core of the compression-stretching process is the design of the compression-stretching process parameters. Under certain mold conditions, the ideal propellant product can be obtained through appropriate process parameters. The existing compression-stretching forming method of propellant powder is to predict the process parameters by using empirical data, input th...
