Embodiment 1

[0023] figure 1 It is a schematic flow chart of a production method for a bulletproof vehicle shell in an embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0024] Step 10: Cut the bulletproof plate according to the shell size of the bulletproof vehicle;

[0025] Further, the bulletproof plate is cut according to the shell size of the bulletproof vehicle, and the cutting method is laser cutting or underwater plasma cutting.

[0026] Specifically, laser cutting or underwater plasma cutting is used to cut and blank the outer panels used in bulletproof vehicles that meet the bulletproof requirements, and the outer panels used in the bulletproof vehicles, that is, the bulletproof panels, are cut into corresponding sizes according to the size of the bulletproof vehicles. The bulletproof plate, the laser cutting or underwater plasma cutting method has the characteristics of less cutting heat, which can minimize the impact of thermal stress on t...

Embodiment 2

[0041] An embodiment of the present invention provides a bulletproof vehicle shell, which is manufactured by the method described in the first embodiment above.

[0042] First, cut the bulletproof plate according to the size of the shell of the bulletproof vehicle, and adopt laser cutting or underwater plasma cutting method to reduce the impact of thermal stress on the bulletproof plate and avoid deformation; then, use the bulletproof plate after cutting The welding wire with the same composition as the base material can be welded by laser welding or argon arc welding. By welding with the same material as the bullet-proof plate, the protective performance equivalent to that of the base material, that is, the bullet-proof plate can be achieved, so that the manufactured The shell of the preliminary bullet-proof vehicle has stable bullet-proof performance during subsequent heat treatment, and then solves the problem of microstructure and precipitation in the weld seam and heat-aff...

Embodiment 3

[0045] In order to explain the present invention more clearly, the actual production process of the production method of a bulletproof vehicle shell of the present invention and the test results of the bulletproof overall performance will be described in detail below through the embodiments of the present invention.

[0046] The chemical composition of the bullet-proof plate used in the shell of the bullet-proof vehicle in the embodiment of the present invention is as follows by weight percentage: C: 0.20-0.45%; Si: 0.20-0.80%; Mn: 1.0-1.8%; Nb: 0-0.06%; Mo: 0.4-1.0%; V: 0-0.10%; Ti: 0-0.08%; Al: 0.01-0.06%; Ni: 0-3.0%; Cu: 0-1.0%; W: 0-2.0%; P : ≤0.011%; S: ≤0.004%; N: ≤0.008%; the rest is Fe and unavoidable impurities.

[0047] In the embodiment of the present invention, an ultra-high-strength bullet-proof board that meets the above-mentioned requirements for the chemical composition of the bullet-proof board is used for specific production. The chemical composition of the b...

Abstract

The invention discloses a shell of a bulletproof vehicle and a production method thereof. The method comprises: cutting a bulletproof plate according to the size of the shell of a bulletproof vehicle; welding the cut bulletproof plate, wherein welding wire and the bulletproof The components of the boards are the same to form a preliminary bulletproof vehicle shell; the preliminary bulletproof vehicle shell is structurally reinforced to form a reinforced bulletproof vehicle shell; the entire reinforced bulletproof vehicle shell is heat treated to obtain a finished bulletproof vehicle shell. It solves the technical problems in the prior art that the bulletproof performance at the position of the welding seam joint is greatly reduced, the phenomenon of breakdown occurs in the target shooting test, and it is difficult to meet the overall protection requirements of the bulletproof vehicle. It has achieved the technical effect that the welded joints of the bulletproof vehicle can achieve the protection performance equivalent to that of the bulletproof plate after heat treatment, which greatly improves the overall safety of the bulletproof vehicle and meets the requirements of the overall bulletproof performance.

Description

technical field [0001] The invention relates to the technical field of bulletproof vehicles, in particular to a shell of a bulletproof vehicle and a production method thereof. Background technique [0002] With the increasing demand for bulletproof vehicles in the military and police fields, high-strength bulletproof panels have begun to be widely used in the field of bulletproof vehicles. For the field of bulletproof plate production, there are relevant introductions both domestically and internationally, but there is no introduction about the use process of bulletproof plate, especially the bulletproof performance of bulletproof vehicle shell made of bulletproof plate at the joint position of bulletproof plate after welding. Difficult problem also is the bottleneck that the prior art that bulletproof vehicle produces is difficult to solve. This is mainly due to the fact that during the welding process of the steel plate, the weld seam and heat-affected zone are affected b...
