Abstract

The invention discloses a device for measuring screw extrusion molding process temperature of a screw extrusion propellant material. The device comprises a motor, a transmission, a testing box, a hydraulic pump, a pillar, a constant-temperature water tank, an underframe, a rotating shaft, a hydraulic oil cylinder, a fixed frame, a hydraulic oil pipe, a friction instrument, a water inlet pipe, a water outlet pipe, a temperature sensor and a computer, wherein the underframe is a truss; the testing box, the hydraulic pump and the constant-temperature water tank are mounted on the underframe; the transmission is mounted on the underframe and positioned above the testing box; the motor is fixed above the transmission and connected with the transmission; the output end of the transmission is connected with the upper end of the rotating shaft; the friction instrument is positioned in the testing box, and the lower end of the rotating shaft downwards penetrates into the testing box and is connected with the friction instrument; a rolling bearing is arranged at the joint of the rotating shaft and the testing box to enable the rotating shaft to rotate around the axis of the rotating shaft. The device can be used for testing the change relation between temperature and friction force and extrusion force, and the change relation can guide the technical personnel in the field to determine the process temperature of the screw extrusion propellant material and a screw rod so as to realize safety trial production of a propellant.

Description

technical field [0001] The invention relates to a device for testing the temperature, friction and pressure of the propellant when it is subjected to screw extrusion in a screw press, and can better guide the formula design and process parameter design of the propellant in the development process, namely the screw press It is a measuring device for the process temperature of the body when the propellant material is screw-pressed. Background technique [0002] my country's screw press propellant molding technology was introduced from Russia in the 1950s. Through the efforts of several generations, we have mastered the molding technology of double-base propellants and modified double-base propellants containing a small amount of RDX and HMX, but the process Theoretical basis research is weak, lack of relevant means and methods of process research, and the design of process parameters depends entirely on experience. In recent years, high-solid screw-press propellants with the a...
