Abstract

The invention discloses a device for manufacturing a propellant grain. The device comprises a cutter head and a cutter handle. A cylindrical cutter column is arranged on the cutter head. A cutter point is arranged at one end of the cutter column, a cutting edge is mounted on the cutter point, a threaded column is connected to the other end of the cutter column, and the outer diameter of the threaded column is smaller than that of the cutter column. The cutter handle is cylindrical. One end of the cutter handle is sunken inwards and provided with a groove, a thread is arranged on the wall of the groove, and the groove is matched with the threaded column. During operation, according to the requirements of shaping the propellant grain, different types of cutter heads and cutter handles can becombined to achieve the purposes of convenient and fast carrying and use. The device is simple in structural design and convenient to use, and good economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of composite solid charging tools, in particular to a device for manufacturing propellant grain columns. Background technique [0002] In the process of composite solid charge, demoulding and shaping is a key process, which will directly affect the apparent quality of the charge and the conformity of the structural size, so as to ensure the normal operation of the engine. Due to the complex surface structure of the medicine type, high size requirements, and the danger of the medicine column, artificial shaping is usually used. In order to ensure the quality and progress, the operators of demoulding and plastic surgery have to have tools of various sizes and styles, which are very inconvenient to carry and store, and cause certain unsafe factors to the site. Contents of the invention [0003] The invention provides a propellant grain manufacturing device to achieve the purpose of being convenient to carry and us...
