Description

Technical Field

[0001] The present invention relates to the technical field of casting explosive forming, and particularly to a water bath cooling device for casting explosive forming that can be sequentially solidified by lifting. Background Art

[0002] Cast charging is a method of heating and melting a low-melting-point solvent explosive, adding high-energy solid-phase components to mix into a fluid with a certain viscosity, and then injecting it into a mold or a projectile body, and cooling and solidifying to form a charge with a certain shape and size. Due to the characteristics of strong ammunition adaptability, high charging efficiency, and low process cost of cast charging, it has been widely used in warhead charging. Due to phenomena such as phase change, volume shrinkage, and heat release during the casting explosive forming process, defects such as pores, cracks, and bottom gaps are easily formed, which not only affect the detonation performance but also easily cause safety problems.

[0003] In the prior art, the solidification device for cast charging in the ammunition charging process has a side door. After manually lifting the projectile body into the device, cooling and solidification are carried out by controlling the water volume in the device. Since the device needs to use water to cool the projectile body and the side door also needs to be sealed, it has a large weight. At the same time, after long-term use, the connection part of the door body is prone to deformation, the side door is difficult to close and the sealing is not tight, resulting in leakage of the cooling water of the cooling device.

The constant temperature water in the water tank 10 is controlled by a mold temperature controller, and the water temperature control accuracy is high, meeting the requirements of high-quality curing.

[0035] For the lifting platform 1 provided by an embodiment of the present application, the lifting is driven by an external drive assembly. In order to improve the running stability of the lifting platform 1 and reduce the overall mass, the embodiment of the present application may provide that the sliding guide rail 2 is located on both sides of the bracket 9, and the lifting platform 1 is connected to the sliding guide rail 2 through a triangular structure steel member; the lifting drive assembly 3 includes a servo motor 4 and a transmission chain assembly, the output shaft of the servo motor 4 is connected to the driving wheel of the transmission chain assembly, and the lifting platform 1 is fixedly connected to the chain of the transmission chain assembly.

[0040] Furthermore, the inner cross-section of the heat-insulating box body 5 is adapted to the outer cross-section of the water tank 10, and the heat-insulating box body 5 is formed by splicing a plurality of heat-insulating baffles. The heat-insulating baffles are made of heat-insulating materials that are relatively light, have good mechanical properties, and low thermal conductivity, which can play a heat-insulating role while reducing the weight. In the actual design and manufacturing process, the gap between the heat-insulating baffle and the water tank 10 can be minimized as much as possible to reliably reduce heat dissipation.

[0041] The constant temperature water in the water tank 10 provided by the embodiment of the present application is supplied through the water inlet 17 by a mold temperature controller and then returns through the water outlet 15.

[0046] The use process of the molten cast explosive forming water bath cooling device provided by the embodiment of the present application includes:

[0047] Before placing the projectile, the lifting platform 1 needs to be lifted to the highest position of the sliding guide rail 2 by the lifting drive assembly 3. After placing the projectile on the projectile support 7, cover it with the sealing cover 6. Then, hot air is introduced through the hot air inlet 11 by a hot air blower, and hot air circulation inside the device is achieved through the hot air outlet 12. At the same time, start the mold temperature controller to realize the internal circulation mode of the water tank 10 from the water inlet 17 to the water outlet 15, and control the water temperature at about 30°C. Lower the lifting platform 1, and as the lifting platform 1 descends, the bottom of the projectile support 7 gradually immerses in water. Since the temperature of the circulating water in the water tank 10 is lower than the temperature of the projectile, the cast explosive inside the projectile can be gradually cooled. At the same time, during the descent process, the sequential solidification of the projectile charge can be achieved by adjusting the descent speed. After solidification is completed, lift the lifting platform 1, remove the sealing cover 6, and take out the projectile to complete the sequential solidification process flow.

[0048] In summary, the cast explosive forming water bath cooling device provided by this application has a simple and reasonable structure, is convenient for installation and use. It meets the high curing requirements caused by the poor fluidity of the cast explosive, solves the problem of defects during the solidification and forming process of the cast charge, reduces the generation of defects in a gradually sequential solidification manner from bottom to top, and effectively reduces the generation of defects such as pores, cracks, and bottom gaps during the solidification process. The sliding guide rail of the lifting platform and the lifting drive assembly are arranged on the support outside the water tank, avoiding the acceleration of corrosion of the sliding guide rail and the lifting drive assembly in a high-temperature and humid environment, extending their service life, and facilitating equipment maintenance.
