Embodiment 1
[0035] Embodiment 1: Fragile warheads for training, using the components of prescription 1, wherein the metal powder is copper, the bonding material is calcium carbonate, and the composite plastic material is polypropylene (PP).
[0036] Preparation method: firstly, according to the firearm standard to be used, a warhead mold is manufactured;
[0037] Secondly, within the temperature range of 140°C to 240°C, inject the metal powder material, bonding material and composite plastic material in the above embodiment into the bullet mold, so that the mixed material becomes a melt.
[0038] Then, in the range of pressure 200pa-300pa, continue to apply pressure to the bullet mold to compact the melt;
[0039] Furthermore, after the metal powder material, bonding material and composite plastic material are injected into the bullet mold under high temperature and high pressure conditions, the bullet mold is cooled;
[0040] Finally, the cooled bullet mold is demolded.
Embodiment 2
[0041] Embodiment 2: Fragile warheads for training, using the components of prescription 2, wherein the metal powder is lead, the bonding material is magnesium carbonate, and the composite plastic material is polyvinyl chloride (PVC).
[0042] The preparation method is the same as in Example 1.
Embodiment 3
[0043] Embodiment 3: Fragile warheads for training, using the components of prescription 3, wherein the metal powder is iron, the bonding material is asbestos, and the composite plastic material is glass fiber reinforced plastic (FRP).
[0044] The preparation method is the same as in Example 1.

Abstract
The invention discloses a training fragile bullet. The training fragile bullet includes a metallic powder material, a binding material, and a composite plastic material. The training fragile bullet includes, by weight, 10-20 parts of the metallic powder material, 37-45 parts of the binding material, and 35-53 parts of the composite plastic material. The invention also discloses a method for manufacturing the training fragile bullet. The method includes the following steps: A, manufacturing a bullet die; B, injecting the metallic powder material, the binding material, and the composite plasticmaterial to the bullet die at the temperature of 140-240 DEG C, allowing the materials to become a molten material, wherein the parts by weight of the materials are 10-20 parts of the metallic powdermaterial, 37-45 parts of the binding material, and 35-53 parts of the composite plastic material; C, continuously applying pressure to the bullet die at the pressure of 200 pa-300 pa, and compacting the molten material; D, cooling the bullet die; and E, performing demoulding on the bullet die.
Description
technical field [0001] The invention relates to a shooting training equipment, in particular to a fragile warhead for training and a manufacturing method thereof. Background technique [0002] Pistols are the most important armed forces in the military forces of various countries at present, therefore, the military forces of various countries all attach great importance to the training of armed forces pistol shooting. During live ammunition training, due to its unique personal danger, most live ammunition training uses target training, which cannot achieve real-person duels, and the actual combat effect of training is poor. [0003] In order to solve the above problems, in the prior art, the patent document with application number 200510042745.5 adopts the technical scheme of filling the hollow warhead body with an inert filler, and then matching the hollow warhead body with a standard cartridge case. So as to effectively solve the technical problems that live ammunition tr...
