as shown in fig. 1, the embodiment provides a processing method for improving the accuracy and efficiency of grooving on the outer wall of the shell, and the method clamps the shell on a lathe for processing; the shell is a body detonation warhead shell 1; the shape of the body detonation warhead shell 1 is a first cylinder and is a revolving body;

the specific processing is carried out according to the following steps:
step 1: turning the surface of the outer side of the shell 1 of the detonation warhead on a lathe;
step 2: processing eight first positive spiral grooves and eight first reverse spiral grooves on the outer surface of a body detonation warhead shell 1 with a processed rotary curved surface directly on a lathe by using a forming lathe tool, wherein the shape of a tool bit of the forming tool is the same as the shape of a section of a groove engraved on the outer surface of the body detonation warhead shell 1, and the eight first positive spiral grooves of the body detonation warhead shell 1 are respectively numbered as positive No. 1, positive No. 2, positive No. 3, positive No. 4, positive No. 5, positive No. 6, positive No. 7 and positive No. 8 along the clockwise direction;
firstly, machining No. 1, no. 5, no. 3, no. 7, no. 2, no. 6, no. 4 and No. 8;
and step 3: eight first reverse spiral grooves of the body detonation warhead shell 1 are respectively numbered as reverse No. 1, reverse No. 2, reverse No. 3, reverse No. 4, reverse No. 5, reverse No. 6, reverse No. 7 and reverse No. 8 along the anticlockwise direction;
firstly, machining the reverse No. 1, the reverse No. 5, the reverse No. 3, the reverse No. 7, the reverse No. 2, the reverse No. 6, the reverse No. 4 and the reverse No. 8;
until the processing of the diamond-shaped groove on the outer surface of the body detonation warhead shell 1 is completed.
As for the spiral rising angle of the first positive spiral groove of the body detonation warhead casing 1, any of the following 2 modes may be adopted:
the processing method for improving the grooving precision and efficiency of the outer wall of the shell provided by the embodiment has the following working principle:
after grooves (rhombic grooves) are carved on the outer surface of the shell of the body detonation warhead, weak areas are prefabricated, and when the shells are thrown, the weak areas break first.
However, the conventional body detonation warhead shell is processed with a prefabricated groove on a milling machine, the processing speed is low, the cost is high, and clamping errors exist in two times of clamping, so that the depth error of the groove is large, and the uniformity of the shell rupture of the body detonation warhead is influenced.
The processing method for improving the precision and efficiency of the grooving on the outer wall of the shell is to process the pre-groove of the shell of the detonation warhead on a lathe, and the defect of processing the pre-groove on the lathe is that a vertical groove cannot be processed, namely the groove cannot be along the axial direction of the shell. But only of the helical type. However, the diamond-shaped grooves can be formed after the spiral grooves are intersected, the same effect as that of the vertical grooves can be achieved by the diamond-shaped grooves, namely, the shells of the warhead part of the detonation are regularly and uniformly broken, and the fuel is uniformly scattered to form regular clouds.
The advantages of processing the pre-groove on the lathe are more. Firstly, the turning speed is higher than that of milling, the cost is low, more importantly, after the outer surface is machined, the body detonation warhead shell is not required to be detached from a lathe and then moved to a milling machine for machining, but the prefabricated groove is directly machined on the lathe, so that the error caused by twice clamping is avoided, and the machining precision of the groove cutting depth is greatly improved. The precision of the depth of the groove can be improved by one order of magnitude, the uniformity of shell breakage of the body detonation warhead part is greatly improved during throwing, the uniformity of fuel throwing is greatly improved, the shape of cloud cluster is more regular, the energy after explosion is better exerted, and the explosion power is larger.
Eight first positive spiral grooves of the body detonation warhead shell 1 are numbered as positive No. 1, positive No. 2, positive No. 3, positive No. 4, positive No. 5, positive No. 6, positive No. 7 and positive No. 8 along the clockwise direction respectively;
firstly, machining a plus No. 1, a plus No. 5, a plus No. 3, a plus No. 7, a plus No. 2, a plus No. 6, a plus No. 4 and a plus No. 8;
eight first reverse spiral grooves of the body detonation warhead shell 1 are respectively numbered as reverse No. 1, reverse No. 2, reverse No. 3, reverse No. 4, reverse No. 5, reverse No. 6, reverse No. 7 and reverse No. 8 along the anticlockwise direction;
firstly, machining No. 1, no. 5, no. 3, no. 7, no. 2, no. 6, no. 4 and No. 8;
the processing sequence is so adopted because after the body detonation warhead casing grooving, can bring certain deformation, should warp and can lead to grooving degree of depth error to increase, and grooving sequence more than adopting is equal to and has carved the opposite side groove after having carved first groove, then trades the angle grooving again, and after the grooving each time, all dwindles the casing deflection that the last grooving brought, minimizes grooving degree of depth error.
The grooving sequence is summarized in practice, so that the grooving depth precision can be optimized.
The spiral rising angles of the first positive spiral groove and the first reverse spiral groove of the body detonation warhead shell 1 are the same.
The inventor finds in tests that when the spiral rising angle of the first normal spiral groove of the body detonation warhead shell 1 is too small, the forward distance of the formed turning tool is too short every time the body detonation warhead shell 1 rotates for one circle on a lathe, namely, the moving speed of the turning tool is too slow, the time of grooving operation is greatly prolonged, and the purpose of improving efficiency is not met.
When the spiral rising angle of the first positive spiral groove of the body detonation warhead shell 1 is too large, the spiral grooves on the outer surface of the body detonation warhead shell 1 are too sparse, namely, the distance between the spiral grooves is too large, namely, the number of the first diamond-shaped grooves on the outer surface of the body detonation warhead shell 1 is too small, the number of the body detonation warhead shell 1 when the shell is broken is reduced, the uniformity of fuel throwing is poor, and the exertion of subsequent explosive power is influenced.
Through partial theoretical calculation, technicians with relevant working experience are summoned to conduct collective negotiation and discussion, the problems are decomposed and are separately evaluated in an experiment, and the final result shows that when the spiral rising angle of the first normal spiral groove of the shell 1 of the body detonation warhead part is 25-30 degrees, the problems can be avoided, the design advantages can be reflected, the function can be well exerted, and the problems can be well solved by using the processing method for improving the grooving precision and efficiency of the outer wall of the shell.
In this embodiment, the spiral rising angle of the first positive spiral groove of the body detonation warhead casing 1 is 25 °;
by using the processing method for improving the precision and efficiency of the grooving of the outer wall of the shell, 1 individual detonation warhead shell is processed, and then 1 individual detonation warhead shell is processed by using the original scheme (lathe and milling machine) for comparison. The depth of the groove is measured, the error of the groove depth of the original method is +/-0.2 mm, the error of the groove depth is +/-0.02 mm by using the processing method for improving the groove precision and efficiency of the outer wall of the shell, and the accuracy of the groove depth is improved by one order of magnitude. The shells of the two individual detonation warhead parts are thrown at the same time, and by using the processing method for improving the grooving precision and efficiency of the outer wall of the shell provided by the embodiment, the cloud cluster formed by the shells of the processed detonation warhead parts is in a regular deformed cylinder shape, and the outline is more regular. The processing method for improving the grooving precision and efficiency of the outer wall of the shell is proved to be effective.
The processing method for improving the grooving precision and efficiency of the outer wall of the shell of the embodiment has the following technical effects:
after the outer surface machining of the body detonation warhead shell is completed on a lathe, a spiral groove is machined on the outer surface of the body detonation warhead shell directly on the lathe through a forming lathe tool, 8 spiral grooves for positive and negative spirals are machined together, the positive and negative spiral grooves are intersected to form a diamond-shaped groove, after the machining is completed, the outer surface of the body detonation warhead shell is fully distributed with uniform diamond-shaped grooves, the uniform breakage of the body detonation warhead shell can be achieved, the fuel is thrown uniformly, and the effect of regular shape of cloud clusters is formed. Therefore, the diamond-shaped groove on the outer surface of the shell of the body detonation warhead does not need to be machined by a milling machine, can be completed only by a lathe, and is only clamped once, so that errors caused by clamping twice are avoided, and the depth precision of the groove is greatly improved; on a lathe, the forming lathe tool and the shell can move at high speed, the processing speed is greatly improved, and the processing cost of the lathe is greatly reduced compared with that of a milling machine.

The depth of the groove is measured, the error of the groove depth of the original method is +/-0.2 mm, the error of the groove depth is +/-0.02 mm by using the processing method for improving the groove precision and efficiency of the outer wall of the shell, and the accuracy of the groove depth is improved by one order of magnitude. The shells of the two individual detonation warhead parts are thrown at the same time, and by using the processing method for improving the grooving precision and efficiency of the outer wall of the shell provided by the embodiment, the cloud cluster formed by the shells of the processed detonation warhead parts is in a regular deformed cylinder shape, and the outline is more regular.
