Embodiment 1

[0036] Such as Figure 1-5 As shown in the figure, a high-efficiency and rapid sampling aid for a medicine-shaped cover includes: a longitudinal cutting support aid and a transverse cutting clamping aid.

[0037] The supporting aids for longitudinal cutting include: placing block 1, supporting base I2 and pad I3; the upper part of pad I3 is provided with supporting base I2, and the supporting base I2 and pad I3 are connected by dovetail keyway connection mode 4; the middle part of the upper surface of supporting base I2 There is a groove 2a, and a placement block 1 is arranged in the groove 2a, and the placement block 1 is connected to the support base I2 through a keyway connection method 5; a semicircular groove 1a is opened in the middle of the upper surface of the placement block 1; longitudinal cutting support aids It is used to support and fix one end of the drug-type cover processing rod when the drug-type cover is cut longitudinally. The radius R of the semicircular gr...

Embodiment 2

[0040] This embodiment provides a method of using the auxiliary device described in Embodiment 1 to cut the pre-cut sample before turning the tensile sample of the drug-type cap.

[0041]Take the drug-type cover with the length L of 220mm, the height h of 90mm, and the processing rod radius of 30mm as an example. The sample to be cut is the pre-cut sample before the tensile sample is turned and formed, and the size is 15mm×60mm×the drug-type cover Cuboids with thick walls, the number is 5.

[0042] Include the following steps:

[0043] Step 1: Clean the surface of the prepared drug-type cover blank to remove oil and stains to ensure that there are no flashes or burrs;

[0044] Step 2: Taking the sample width of 15mm as the unit, divide the drug-type cover equally;

[0045] Step 3: Adjust the clamping distance through the hand wheel of the sawing machine. The clamping distance is slightly larger than the longitudinal horizontal length of the drug-type cover by 220mm;

[0046...

Embodiment 3

[0054] This embodiment provides a method for cutting a test sample for grain size detection of a drug-type mask using the auxiliary device described in Embodiment 1.

[0055] Take the drug-type mask with the length L of 220mm, the height h of 90mm, and the radius of the processing rod of 30mm as an example. The samples to be cut are the test samples of the drug-type mask grain size. Take a piece of cuboid respectively, and take a piece of metal block with a size of 12mm×12mm×wall thickness of the medicine-shaped cover at the mouth, middle and top of the medicine-shaped cover corresponding to the cuboid.

[0056] Include the following steps:

[0057] Step 1: Clean the surface of the prepared drug-type cover blank to remove oil and stains to ensure that there are no flashes or burrs;

[0058] Step 2: Take the sample width of 12mm as the unit, draw lines at the symmetrical positions of the drug-type cover;

[0059] Step 3: Adjust the clamping distance through the hand wheel of ...

Description

technical field [0001] The invention relates to the technical field of detection and sampling of metal materials, and in particular provides an auxiliary tool for efficient and rapid sampling of a drug-type mask and a sampling method. Background technique [0002] As the core component of the armor-piercing warhead, the medicine-shaped cover has an important influence on the penetration power of the warhead. As the key component of the shaped charge warhead, the liner cover has been developed for more than 50 years. 98% of the armor-piercing projectile warheads in active service use pure copper liner covers. [0003] With the development of a new generation of explosive reactive armor, ceramic armor, and composite armor, pure copper liner can no longer meet the development needs of high-performance warheads. In recent years, foreign countries have successfully developed high-density functional drug-mold materials such as tantalum alloy, tungsten alloy, and uranium alloy. ...
