Embodiment 1

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

[0024] Step 10: Cut the bulletproof board according to the shell size of the bulletproof car;

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

[0026] Specifically, the outer panel of the bulletproof car that meets the bulletproof requirements is cut by laser cutting or underwater plasma cutting, and the outer panel used for the bulletproof car, that is, the bulletproof plate, is cut into corresponding sizes according to the size of the bulletproof car The laser cutting or underwater plasma cutting method has the characteristics of less cutting heat, which can minimize the impact of thermal stress on the bulletproof board, thereby avoiding the deformation of the b...

Embodiment 2

[0041] An embodiment of the present invention provides an armored car shell, which is processed by the method described in the first embodiment.

[0042] First, cut the bulletproof board according to the size of the armored car shell, which adopts laser cutting or underwater plasma cutting to reduce the thermal stress on the bulletproof board and avoid deformation; then, use the cut bulletproof board The welding wire with the same composition as the base material can be welded by laser welding or argon arc welding. By using the same material as the bulletproof plate for welding, the protection performance equivalent to the base material, that is, the bulletproof plate can be achieved, so that the manufacturing The shell of the preliminary bullet-proof car has stable anti-ballistic performance during the subsequent heat treatment, which solves the problem that the welding seam and the heat-affected zone are affected by the heating of the welding heat input during the welding proces...

Embodiment 3

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

[0046] The chemical composition of the bulletproof plate used in the shell of the bulletproof vehicle according to the embodiment of the present invention is as follows: C: 0.20-0.45%; Si: 0.20-0.80%; Mn: 1.0-1.8%; Nb: 0-0.06%; Mo: 0.4 to 1.0%; V: 0 to 0.10%; Ti: 0 to 0.08%; Al: 0.01 to 0.06%; Ni: 0 to 3.0%; Cu: 0 to 1.0%; W: 0 to 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 bulletproof board that meets the chemical composition requirements of the above-mentioned bulletproof board is used for specific production. The chemical composition of the adopted bull...

Abstract

The invention discloses a bulletproof vehicle shell and a production method thereof. The method comprises the following steps that a bullet-proof plate is cut according to the size of the bulletproofvehicle shell; a cut-off bulletproof plate is welded, wherein the material of a welding wire for welding is the same as that of the bulletproof plate, and a primary bulletproof vehicle shell is manufactured; and the primary bulletproof vehicle shell is structurally reinforced, and a reinforcing bulletproof vehicle shell is formed; and heat treatment is carried out on the whole reinforced bulletproof vehicle shell, and a finished product of the bulletproof vehicle shell is obtained. The technical problems that the bulletproof performance of the joint position of a weld joint is greatly reduced,the breakdown phenomenon of a targeting test occurs, and the overall protection requirement of a bulletproof vehicle is difficult to meet are solved. The protective performance equivalent to that ofthe bulletproof plate is achieved after the weld joint of the bulletproof vehicle is subjected to heat treatment, the overall safety of the bulletproof vehicle is greatly improved, and the technical effect of meeting the requirement of the overall bulletproof performance is met.

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 production of bulletproof panels, there are relevant introductions both domestically and internationally. However, the use of bulletproof panels, especially the use of bulletproof panels to make bulletproof car shells, is not introduced at the joint position of the bulletproof panels after welding. The problem is also a bottleneck that is difficult to solve with the existing technology in the production of bulletproof vehicles. This is mainly because during the welding process of the steel plate, the welding seam and the heat-affected zone are affected by the heating of the welding hea...
