Drug column coated gel flash trimming device and trimming method

Abstract

The invention discloses a repairing device and a repairing method for a drug column coated gel flash. The device includes a horizontal base, on which a horizontal turntable for placing medicine columns is arranged, a vertical column that can slide left and right on the horizontal base is arranged on one side of the horizontal turntable, and the upper part of the vertical column is provided with a horizontal One side of the turntable is suspended in the air and can slide up and down along the vertical column. The middle of the head of the knife handle assembly is provided with a horizontally suspended probe block assembly that can measure the height of the center of the top of the powder column. The knife handle The upper surface of the head of the assembly is provided with an upper blade assembly that is horizontally suspended and is used for horizontally cutting the gel flash of the powder column, and the lower surface of the head of the handle assembly is provided with an inclined upward arrangement for oblique Lower blade assembly that cuts the gel-coated flash of the grain. The repairing device and the repairing method are applicable to a wide range of grains, and have good flash cutting effect, which ensures the quality of grains and improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of explosive device grain processing, in particular to a grain coated gel flash trimming device and a trimming method thereof. Background technology [0002] Grain is a solid propellant with certain geometry and size, which is used to be placed in the combustion chamber of solid rocket motor. In order to improve the mechanical properties of propellant, the geometric size of grain is strictly required in engine combustion chamber. The coated gel shall be used for storage after the manufacturing of the grain. Due to the thermal expansion and cold contraction of the gel, there is a certain height of gel flash around the upper surface of the grain after disassembly and packaging. In the actual use process, in order not to affect the overall height of the grain, it is necessary to clean the gel flash of the grain. [0003] At present, manual hand-held blades are commonly used to clean gel flash in production. However,...

Problems solved by technology

[0003] At present, manual hand-held blades are generally used to clean the gel flash in production. However, there are certain disadvantages in manual cleaning: first, the powder column is fragile and not easy to clamp; second, the height of the gel flash is small, and after solidification The hardness of the gel is high, manual removal is easy to damage the powder column, making the round edge of the powder column uneven, affecting the use of the powder column
