Embodiment 1
[0031] The milling cutter used for end milling of solid propellant in this embodiment is mainly used for end milling of the same batch and shape of propellant grains with a length of 240 mm, a diameter of 70 mm, a length of 220 mm, and a diameter of 100 mm.
[0032] Wherein, the adjusting screw 9 is driven by a manual turntable.
Embodiment 2
[0034] The milling cutter used for solid propellant end face milling in this embodiment is mainly used for various types of propellant charges such as 130mm in length, 22mm in diameter, 80mm in length, 12mm in diameter, 14mm in length, and 14mm in diameter. Face milling for mixed production of columns.
[0035] Wherein, the adjusting lead screw 9 is driven by a motor, which can automatically adjust the distance between the two milling cutters and adapt to different types of propellant products.

The invention belongs to the technical field of cutter machining, in particular to a milling cutter for milling the end surface of a solid propellant. The milling cutter comprises two sets of symmetrically arranged milling cutters, a transmission shaft, a drive motor, a support and an adjusting lead screw. A dust recovery hole is formed in the center of the milling cutters, an airflow channel is formed in the transmission shaft and the drive motor, the airflow channel is connected with a dust recovery device through a rotary joint, the milled propellant dust and debris are directly recycled inthe milling cutters, the energy consumption is low, the dust is not easy to fly, meanwhile, the position of the milling cutters can be adjusted through the adjusting lead screw, so that the propellant products with different lengths can be used. According to the milling cutter, the defects of the propellant grain turning process, the end surface dressing process, the dust treatment and the like are overcome, dust generated in milling can be recovered and milled in a relatively small energy consumption set, the safety of finishing the end surface of the propellant is improved, the flexibilityis higher, the application range of the equipment is expanded, the waste is reduced, and the energy consumption is reduced.
Description
technical field [0001] The invention belongs to the technical field of cutter processing, and in particular relates to a milling cutter for solid propellant end face milling. Background technique [0002] At present, the quality of solid propellants for military equipment is getting higher and higher, so it is necessary to strictly control the appearance, shape and weight of solid propellants. [0003] Commonly used solid propellant screw press, hydraulic stretching and other forming processes all need to cut off the grain. During the cutting process, problems such as flash, burr and length deviation cannot be avoided, which makes the appearance of the grain unsatisfactory. Requirements, weight and other indicators vary greatly. The solution taken now is to reserve a certain length when cutting, and then turn the grain to ensure product quality. However, there is a lot of waste of materials, and at the same time, a vehicle chemical process is added, and a large amount of d...
