Description

Forming device using surface roughness measuring instrument

Technical Field

The invention belongs to the technical field of forming devices, relates to a cylindrical body roll welding forming device, and particularly relates to a forming device utilizing a surface roughness measuring instrument.

Background

The high-energy liquid-phase fuel is thrown into the air through the explosive explosion throwing driving action, the high-energy liquid-phase fuel is atomized and mixed with the air to form a large-range active cloud cluster, and the active cloud cluster generates body detonation through secondary explosive initiation to release strong shock waves, so that the high-energy liquid-phase fuel weapon is one of the most powerful weapons.

The field and garden et al report in the literature "numerical simulation study of the effect of cloud and mist morphology on detonation pressure field" (safety and environmental bulletin, 8 months in 2013, vol 13, page 182 of 4 th): the attenuation of the wave speed of the explosive shock waves of the body detonation warhead is slowed down along with the increase of the radial size of the cloud cluster, and the shock wave pressure is increased along with the increase of the radial size of the cloud cluster at the same position outside the detonation region of the cloud cluster. I.e., the explosive power of the body detonation warheads, increases with increasing diameter of the throw cloud. To increase the diameter of the cloud formed by the high-energy fuel throwing, the bulk detonation warhead is typically designed as a thin-walled shell structure.

Li xiuli et al reported in the literature "application of infrared thermography technology in cloud explosion thermometry" (energetic materials, 6 months 2008, vol 16, p 3 344): for the body detonation warhead, if the shell is not grooved, after scattering, the shell is broken unevenly, so that fuel scattering is uneven, the fuel is easy to deviate to one side of the shell which is broken first, and after secondary detonation, the power is insufficient; after the shell is grooved, fuel is scattered uniformly and annularly and uniformly, and after secondary detonation, the output of the energy of the explosion wave is improved, the damage effect is obviously improved, and the power of a warhead is improved. Therefore, it is necessary to notch the outer wall of the housing.

In order to reduce the flight resistance of the body detonation warhead, the warhead needs to have a better aerodynamic profile. Hanyupin et al reported in the literature "an ultrasonic measuring method of the volume of a medicine chamber based on the external dimensions of a projectile" (Bomb and guidance bulletin, 2.2013, 33, vol. 1, page 77): the outer surface of the warhead shell is a revolving body with an arc generatrix. The air resistance can be reduced, and the launching flight of the warhead is facilitated.

In conclusion, the shell of the body detonation warhead is a circular arc generatrix curved cylinder with grooves on the outer surface.

Generally, the molding process of a simple cylinder is: and rolling the plate into a cylinder by using a plate rolling machine and then welding and forming. Ai dao et al reported the process of rolling steel sheet into a cylinder in the document "seal edge rolling process and automatic rolling die" (die industry, 2000, vol. 9, page 20). However, the plate bending machine can only roll the plate into a cylindrical cylinder or a conical cylinder, and the plate bending machine cannot roll the plate into a cylinder with an arc-shaped generatrix curved surface.

Therefore, the conventional processing method of the circular-arc generatrix curved cylinder with the groove on the outer surface comprises the following steps: firstly, casting a curved cylindrical blank, then, carrying out finish machining on the inner surface and the outer surface of the cylinder body, and then, grooving on the outer surface of the curved cylinder body.

(1) For a warhead shell with the diameter of 1m and the length of 2m, by adopting the process, the price of a cast aluminum blank is about 9 ten thousand yuan, and the prices of the machined inner surface, the machined outer surface and the machined grooves are about 8 ten thousand yuan, which is 17 ten thousand yuan in total. The cost is high, and the national capital consumption is huge when weapons are provided for military in large batch.

(2) The weight of the cast blank is about 3-5 times of the weight of the finished product, namely 80% of the blank is cut, and metal resource waste is huge.

(3) The total time of casting and machining is about 1 month, and the machining period is too long.

(4) The casting belongs to a hot working process, is a heavy pollution industry, is not beneficial to environmental protection, and does not accord with the green production advocated by the state.

(5) The lower limit of the tensile strength of the cast aluminum 114A is 290MPa, the lower limit of the elongation is 2%, and in the field of metal materials, the mechanical parameters are lower, and the performance of the material is poorer.
