Problems solved by technology

[0003] Extrusion holes with the same shape and size are set on the mold. Although the physical parameters of the explosives in the cavity are the same, due to the extrusion of the piston, the flow rate of the explosives at the center of the outer cylinder is greater than that at the circumference of the outer cylinder. The flow rate causes the outflow of propellant and explosives at the center of the outer cylinder to be greater than that at the circumference of the outer cylinder, which will not only have a certain impact on the subsequent cutting work, but also affect the quality of the extruded propellant and explosives

Abstract

The invention provides a uniform flowing squeezing device and a squeezing method, and relates to the field of energetic material processing. The device comprises a flow uniforming device and a tube body, the flow uniforming device comprises a piston, a first abutting part, a second abutting part, a third abutting part, a first elastic member and a second elastic member, the tube body comprises a bottom wall, a plurality of squeezing holes arranged at intervals are formed in the bottom wall, and the flow uniforming device is arranged in the tube body and can move in the axial direction of the tube body to selectively get close to the bottom wall to uniformly squeeze material from the squeezing holes. According to the flow squeezing device, different squeezing regions can be formed by the uniform flowing squeezing device to allow the quality of the material to be uniform, the quality of the extruded material is effectively ensured, and the material meets subsequent drug cutting demands.

Description

technical field [0001] The invention relates to the field of energetic material processing, in particular to a flow equalizing extrusion device and an extrusion method. Background technique [0002] The working principle of the propellant extruder is to extrude the propellant in the outer cylinder through the extrusion hole on the mold by exerting force on the piston to form a strip of propellant. [0003] Extrusion holes with the same shape and size are set on the mold. Although the physical parameters of the explosives in the cavity are the same, due to the extrusion of the piston, the flow rate of the explosives at the center of the outer cylinder is greater than that at the circumference of the outer cylinder. The flow rate causes the outflow of explosives at the center of the outer cylinder to be greater than that at the circumference of the outer cylinder, which will not only have a certain impact on the subsequent cutting work, but also affect the quality of the extru...
