Embodiment Construction

[0027]This device design support plate [5] is a steel material, two left and right, symmetrically installed on the left and right sides on the base [6], fixed with bolts. The base [6] is made of steel, and the material of the designed square bar [3] is made of steel, which is installed in the grooves at the top of the left and right sides of the support plate [5]. The left and right grooves are symmetrical and close to the inside of the groove , install one bushing [4] symmetrically at the left and right ends of the square rod [3], and then install a set of cams [11] symmetrically on the bushings [4] in turn. There are two left and right cams [11]. Outer end of the groove, the prolongation of square bar [3] connects and rotates and presses handle [14]. The design upper tool rest [8] is a steel material, and its main function is to fix the upper knife [9]. The upper knife [9] is made of stainless steel. The strengthening of this steel is achieved by solid solution treatment, c...

Abstract

The invention discloses a set of device for rapidly preparing stability test samples of gunpowder and explosives, and solves the problems that the stability test samples of the gunpowder and the explosives are low in preparation efficiency, long in consumed time and difficult to collect. The device comprises a knife rest part, a base part and a sample collecting part. According to the device, the samples can be prepared with the specification and size required by testing regulations once in continuous feeding and intermittent shearing stress manners; by virtue of a drawer type sample collector, the spattering of gunpowder particles can be effectively prevented. The device has the beneficial effects that the operation is easy, the time and the labor are saved, the test cycle can be greatly shortened, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of physical and chemical performance testing of explosives, and mainly relates to a sample rapid preparation device for the stability test of explosives. technical background [0002] The stability of explosives is an important evaluation index for the development, safe production and storage of intrinsically safe formulas of explosives. The sample methods include vacuum stability, Abel, methyl violet, Violet, etc. The test is to heat the sample at a specified temperature , measure the gas volume released by the thermal decomposition of the sample, or judge the chemical stability of the propellant and explosive by the discoloration of the special test paper caused by the decomposition product. For the above test methods, the national military standard GJB772A stipulates the specifications and dimensions of the test samples to ensure the accuracy and reliability of the test data. In actual operation, various stability...
