Pneumatic weight press

Abstract

The invention discloses a pneumatic weight pressure device, which is an initiating explosive device. The equipment is used for pressing powder in the initiating explosive device placed in a die; by the equipment, the explosive can be made into an necessary explosive column; the equipment uses a gas cylinder as a power source, uses a weight for constant pressure and uses a lead screw mechanism to adjust the distance between the die and a press head; and a pneumatic delay timer is used for the stepless adjustment of the pressure keeping time when the explosive is pressed. The whole equipment is fully operated by pneumatic control, all elements in the equipment, including a position detection element, are pneumatic elements, and electric control structures and elements are not used, so that the pneumatic weight press of the invention is safe in nature.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and relates to a device for pressing explosives, in particular to a pneumatic weight pressing machine. Background technique [0002] The powder press machine is the key equipment for the assembly of pyrotechnics, and the density and consistency of the pressed powder have a direct impact on the explosive performance of pyrotechnics. At present, the equipment commonly used for suppressing pyrotechnic products in China includes hydraulic presses, lever presses, and hand screw presses. There are some shortcomings in these pressing equipment: [0003] First of all, after the hydraulic press works for a period of time, the temperature of the hydraulic oil will rise, resulting in unstable pressure; [0004] Secondly, after the lever press has been used for a period of time, the knife edge of the lever will be worn, and the pressure accuracy cannot be guaranteed when the knife edge is worn; [0005]...

AI Technical Summary

Problems solved by technology

[0003] First of all, after the hydraulic press works for a period of time, the temperature of the hydraulic oil will rise, resulting in unstable pressure;

[0004] Secondly, after the lever press is used for a period of time, the knife edge of the lever will be worn, and the pressure accuracy cannot be guaranteed when the knife edge is worn;

[0005] Although the pressure accuracy of the hand-driven screw press is relatively accurate, it is necessary to manually pull the press when it is working, so the time to control the pressing of the medicine is determined manually. The speed of the medicine is inconsistent, resulting in poor consistency, and the press is manually pulled, and the weight is pushed up manually, which is a lot of labor
