Description

Technical Field

[0001] The invention belongs to the field of composite solid propellant sample production and processing, and in particular relates to a composite solid propellant mechanical property test and static burning rate test sample full-automatic remote control production and processing system. Background Art

[0002] As an energetic material, solid propellant not only provides energy for solid motors, but also has certain dangers. Due to the stimulation of external excitation sources such as heat, mechanical impact, friction and electrostatic field, solid propellant may cause combustion, explosion and other accidents. In particular, the development and application of new high-energy raw materials in recent years have made great progress in high-energy propellants. However, the increase in energy has brought about significant safety issues in the production, transportation, storage and use of solid propellants. During these processes, the propellants are subjected to combustion and explosion accidents caused by external stimuli such as accidental falls, impacts, and heat, which not only cause fatal damage to weapons and equipment, but also may cause a large number of casualties and huge economic losses.

[0003] When conducting mechanical properties and static burning rate tests on composite solid propellants, it is necessary to use composite solid propellant square billets as raw materials and process various forms of specimens (dumbbell-shaped specimens for mechanical properties testing and strip-shaped specimens for static burning rate testing).

[0004] The preparation process of propellant dumbbell specimens is shown in Figure 1 , including: (1) the square billet is divided into two sections; (2) one section is divided into four blocks along the casting direction; (3) each block is divided into several pieces with a thickness of 10 mm; (4) a dumbbell-shaped specimen is made.

[0005] The preparation process of burning rate test specimens is shown in Figure 2 , including: processing the composite solid propellant square billets into (4mm±0.5mm), (5mm±0.5mm) or (10mm±0.5mm) specimens one by one along the casting direction, and then laying the single specimen pieces flat and using a slicer to process them one by one into (4mm±0.5mm)×(4mm±0.5mm)×150mm, (5mm±0.5mm)×(5mm±0.5mm)×150mm, or (10mm±0.5mm)×(10mm±0.5mm)×150mm medicine strips.

[0006] The entire sample preparation process requires operators to use large guillotines, pneumatic slicers (strips), pneumatic tablet presses and other devices to complete the work manually at close range. During this process, the cutters will frequently cause friction, extrusion, collision and other stimulations to the composite solid propellant; and because the operator is in close contact with the propellant, there is a risk of the human body releasing static electricity to the propellant, especially in dry winter weather. The above potential factors may lead to accidents such as combustion and explosion of solid propellants, posing a major safety hazard.

[0007] Therefore, it is of great significance to establish a remote-controlled fully automatic processing system for composite solid propellant test specimens, realize fully automated operation of the composite solid propellant test specimen preparation process, physically isolate operators and propellant preparation, and ensure the safety and reliability of the composite solid propellant test specimen preparation process. Summary of the invention

[0008] In view of the current situation that the whole process of composite solid propellant sample preparation needs to be completed by operators manually working at close range, which poses a major safety hazard, the present invention aims to provide a remote-controlled fully-automatic processing system for composite solid propellant test samples, so as to realize fully-automatic operation of the composite solid propellant test sample preparation process, physically isolate operators and propellant sample preparation, and ensure the inherent safety of the composite solid propellant test sample preparation process.

[0051] The function of the sample preparation system 3 is to prepare the sheet-like intermediate blanks operated by the operation system 2 according to the size requirements set by the program. The operation system 2 operates the sheet-like intermediate blanks to the sample preparation plane 24, and the eighth drive mechanism 88 (such as a cylinder or an explosion-proof motor) works to drive the push plate 22 to move to the placement position of the sheet-like intermediate blanks and fix the sheet-like intermediate blanks. The fifth drive mechanism 85 (such as a cylinder or an explosion-proof motor) works to drive the sample preparation plane 24 as a whole to move along the second horizontal guide rail 231 and accurately position it below the dumbbell-shaped tool 18 or the blade 21. If the program sets a dumbbell-shaped sample, it moves to the bottom of the dumbbell-shaped tool 18; if the program sets a strip-shaped sample, it moves to the bottom of the blade 21. Taking the strip sample as an example, the second horizontal guide rail 231 moves precisely according to the sample size set by the program, and each time it moves, the blade 21 works downward once to complete the sample preparation; after completion, the second horizontal guide rail 231 continues to move the distance set by the program, and the blade 21 continues to work, and the process is repeated in sequence until the number of samples prepared reaches the number set by the program and then stops; after the sample preparation is completed, the fifth driving mechanism 85 drives the sample preparation plane 24 to move to the sample unloading mechanism 17, and the unloading part of the sample unloading mechanism 17 pushes the sample and waste together and puts them into the sample collection box 26 for temporary storage.

[0052] After the knife 6 in the slicing system 1 moves downward once to complete a slice, the knife 6 is reset, and the operating system 2 works at the same time, and the cut sheet-like intermediate blank is transferred to the sample preparation system 3 by the coordinated work of the transfer suction cup 16, the swing mechanism 15, and the transfer mechanism 14; then, the sample preparation system 3 starts to work and prepare samples; at the same time, the operating system 2 is reset, and the knife 6 in the slicing system 1 starts to work again, entering the next cycle, and the two systems work synchronously.
