Before operation, the grain sample preparation machine is adjusted to be horizontal by adjusting the supporting legs.

[0040] The above-mentioned composite solid propellant ring type grain sample preparation equipment is used for sample preparation, in this embodiment, the propellant ring type grain with a height greater than 150mm and less than 270mm is cut at a height of 150mm, then the 150mm high ring type grain is cut into two halves to form two half cylindrical ring type grains, and finally the half cylindrical ring type grain is cut into mechanical or burning rate grain tablets with a certain thickness. Specifically, the following steps are included:

[0041] Step 1, fix the slide table 1 with the base plate 2, and make the distance between the support of the pressure component 8 and the cutter 6 consistent with the fixed height dimension of the ring-shaped charge column 00. In this embodiment, the distance can be adjusted according to 150-160mm. First, the operator marks the cutter position and the cutter holder position on the slide table of the sample preparation machine, and marks the segmentation line on the ring-shaped charge column.

[0042] Step 2, the personnel enters the isolation room, and places the ring-shaped charge column 00 with a height greater than 150mm and less than 270mm horizontally on the slide table 1. One end of the ring-shaped charge column 00 is positioned close to the support 81 of the pressure component 8, and the other end of the ring-shaped charge column 00 is fixed to the front segment of the ring-shaped charge column close to the right-angle fixing part 14, which is fixed on the slide table 1 by screws.

[0043] Step 3, the personnel leaves the isolation room, and the personnel in the control room observes through video monitoring, controls the cutter driving part on the central control console, drives the cutter 6 to cut the end of the ring-shaped charge column 00, and completes the fixed height of 150mm of the ring-shaped charge column. For different sizes of cutters or ring-shaped charge columns, one-time cutting or multiple cutting can be selected according to the actual situation.

[0044] Step 4, after the cutter is reset, the personnel enters the isolation room, stands the ring-shaped charge column vertically on the slide table, adjusts the position, fixes one side of the ring-shaped charge column 00 by the pressure component 8, and starts the cutter driving part 5 to drive the cutter 6 to segment the ring-shaped charge column 00. For the ring-shaped charge column with a larger diameter, single cutter one-time segmentation processing is adopted, and the requirements for the cutting tool and the pushing force are higher. Therefore, the method of first decomposing the cylindrical column and then slicing is adopted. The decomposition of the ring-shaped charge column is to decompose the ring-shaped charge column into two half-cylindrical square blanks by twice clamping and twice cutting.

[0045] As shown in Figure 9 , 10 , the ring-shaped charge column 00 with a height of 150mm is fixed on the slide table 1, the cutter holder 52 is pushed by the sample preparation cylinder 51 to segment the single side of the ring-shaped charge column 00. Then the ring-shaped charge column is positioned and segmented twice to achieve the purpose of segmenting the ring-shaped charge column into two pieces. During this period, after the first segmentation, the personnel enters the isolation room, rotates the ring-shaped charge column by 180 degrees, adjusts the position, and fixes it. The personnel leaves and again segments the charge column by operating remotely in the living room.

[0046] Step 5, fix the segmented half-circular charge column, start the cutter driving part 5 to drive the cutter 6 to slice the ring-shaped charge column 00, and realize equidistant slicing by using the equidistant feeding assembly 7.

[0047] In this embodiment, the half-circular charge column 01 is processed into 10mm or 4mm thick tablets. As shown inFigure 11 、 12 As shown in FIG. 8, the semicircular grain 01 is placed on the sliding table 1, the operator adjusts the position of the semicircular grain 01, uses the rear-end pressing cylinder 82 to press the semicircular grain, the personnel leave, and the control room remotely controls the cutter to cut, each time the cutting is performed, the gear shifting mechanism 73 pushes the sliding table 1 to displace 10 mm or 4 mm forward, until the required grain sample cutting is completed.

[0049]
