Embodiment 1

[0023] Grinding rod structure: such as figure 1 As shown, the grinding rod is composed of a sleeve 1, a buffer rod 2, a grinding rod core 3, a buffer spring 4, a force-measuring spring 5, a scale 6, a limit stop ring 7 and a limit screw 8. Sleeve 1 is made of ceramic material, with a streamlined appearance suitable for gripping. The barrel body is cylindrical, with a hemispherical top and a circular opening; the surface of the barrel body is symmetrical with two limiting grooves, and the bottom of the barrel is an opening. Fixed with the annular limit stop ring 7 by screws;

[0024] The buffer rod 2 is cylindrical, the upper part is located inside the sleeve, and the lower end protrudes from the limit stop ring 7; the middle part of the buffer rod body is equipped with two limit screw rods 8 through symmetrical threaded holes; the limit screw rods are covered with buffer springs 4 , the outer diameter of the buffer spring is greater than the width of the limit groove; the dia...

Embodiment 2

[0029] Grinding rod structure: The grinding rod core is made of agate, and the scale surface has three indicator colors of green, yellow and red from top to bottom, representing safety, risk and danger respectively. Other structures are the same as in Embodiment 1.

[0030] This manual grinding rod is suitable for specific explosives or pyrotechnic products with a specific friction sensitivity range. The length of the green, yellow, and red color ranges on the scale can be verified by conducting trace and multiple tests on specific explosives or pyrotechnics with a specific friction sensitivity range, and the safety and hidden dangers of this type of pyrotechnics. and dangerous grinding strength are distinguished, and are represented by three colors on the scale.

[0031] Use of grinding rod: When in use, the processed sample is placed in the grinding bowl, and the operator holds the sleeve of the grinding rod to gently squeeze and rub the processed sample. When the operator...

Abstract

The invention discloses a grinding bar with a buffering and indication effect. The device is mainly composed of a sleeve, a buffering bar, a grinding bar core, a buffering spring, a force measuring spring, a dividing ruler and a limiting stop ring. The grinding bar core is arranged above the buffering bar, and connected with the sleeve through the buffering spring and the force measuring spring. The dividing ruler is located at the top end of the buffering bar, and stretches out of an opening in the top end of the sleeve. During usage, the grinding bar transmits force to the grinding bar corethrough the buffering spring and the force measuring spring. On one hand, sudden increasing of grinding force can be avoided; and on the other hand, the current grinding strength can be visually displayed through the dividing ruler at the top end of the sleeve. The device is applicable to grinding of explosives and powders and energetic materials of the initiating explosive device industry, and the production and personal safety of grinding procedure operators can be guaranteed.

Description

technical field [0001] The invention relates to a grinding rod, which is suitable for the grinding process in the pyrotechnics industry and the research of energetic materials. Background technique [0002] In the production and research of hazardous chemicals, in order to meet the process requirements, it is often necessary to crush or grind solid materials into powders to increase their contact area and increase the chemical reaction speed. In the explosives industry, the grinding of energetic materials is a very dangerous process. When grinding pyrotechnics manually, excessive grinding force and too fast speed may cause combustion or explosion accidents. In recent years, the speed of research in the explosives industry has been accelerated, and safety production accidents caused by grinding have occurred frequently. After exploring the reasons, it is not difficult to find that due to the lack of understanding of the processing samples, the grinding speed, especially the...
