Description

[0002] Currently, the solidification process of molten charge solidification is controlled by a probe method. This involves inserting a heated probe into the molten charge and gradually increasing its height to lower its temperature, thus controlling the solidification process. However, due to the low specific heat of the heat transfer medium, this method of solidification control has poor temperature precision, resulting in generally poor solidification performance and defects such as porosity, cracks, and gaps. It is only suitable for products with less stringent requirements.

[0003] Another method for solidifying cast propellants is to control the temperature of the solidification process using a water bath. This involves immersing the product shell in water and gradually adjusting the water temperature and level to control the solidification process. However, this method lacks flexibility in temperature control, limiting solidification control to top-down processes and potentially leading to defects such as bottom gaps. Summary of the Invention

[0019] A positive pressure unit 30 is connected to the triaxial module 20. The positive pressure unit 30 is connected to an external positive pressure device via a pipe. In a specific implementation, the positive pressure unit 30 may include a main frame 31, a sealing cover 32, a gripper assembly 33, a gripper cylinder 34, a universal joint 35, and a guide shaft 36. The upper end of the guide shaft 36 is connected to the Z-axis module 23, and the lower end of the guide shaft 36 is connected to the upper end of the main frame 31 via the universal joint 35. The sealing plate is connected to the lower end of the main frame 31. One end of the gripper cylinder 34 is connected to the main frame 31, and the other end of the gripper cylinder 34 is connected to the gripper assembly 33. The gripper cylinder 34 is used to perform a push-pull action to open or close the gripper assembly 33, so that in the closed state, the sealing cover 32 is locked to achieve a sealed connection with the top riser of the molten charge product 80.

[0020] A transfer fixture 70 is used to transport the molten charge product 80. The transfer fixture 70 is provided with a plurality of jacket assemblies 50. In a specific implementation, the jacket assembly 50 may include a pair of jacket bodies 51, which are connected by a detachable quick clamp 52. To improve heat transfer efficiency, the inner side of the jacket assembly 50 may be provided with heat transfer plates 53.

[0021] The docking unit 40 includes a female head assembly 42 and a male head assembly 43. The female head assembly 42 is fixedly connected to the triaxial module 20, and the male head assembly 43 is connected to the transfer tooling 70. The female head assembly 42 is connected to an external hot water circulation temperature control device through a pipe, and the male head assembly 43 is connected to several of the jacket assemblies 50. In a specific implementation, the embodiments of this application may provide that the female head assembly 42 is equipped with a docking cylinder 41, which is used to drive the female head assembly 42 to move, so as to realize docking with the male head assembly 43.

[0022] The control unit is connected to the triaxial module 20, the positive pressure unit 30, the docking unit 40, the external positive pressure device, and the external hot water circulation temperature control device. To facilitate user operation, the controller is connected to a touch screen 60, which is mounted on the base 10.

[0023] After several of the jacket assemblies 50 have been moved by the transfer fixture 70 to the cooling station and manually fixed to the surface of the molten charge product 80, the control unit is configured to perform the following operations: The docking unit 40 is controlled to dock the male connector 43 with the female connector 42; The system receives control parameters input by the user, including dimensional parameters corresponding to the model of the molten casting charge product 80 and the target solidification method. In specific implementation, the target solidification method may include any one of positive pressure solidification, water bath solidification, or a combination of positive pressure and water bath solidification.

Control the operation of the external positive pressure device and / or the external hot water circulation temperature control device to perform the target solidification method to cool the molten casting charge product 80.

[0025] The casting cooling device for molten explosives provided in this application uses servo motors to control the XYZ axes of the three-axis module 20, enabling automated and precise docking for products of different sizes. The pressure water bath jacket composite cooling device for casting explosives employs multiple independent water bath jackets, allowing for zoned temperature control. The heat source docking between the jackets and risers uses self-sealing quick connectors, providing rapid and automatic docking. Additional channels are reserved to increase the number of water bath jackets, enabling more areas of precise temperature control. The pressure water bath jacket composite cooling device for casting explosives also features a pressurization function, allowing the molten explosive to solidify under positive pressure, thus reducing defects.

[0026] The casting and cooling device for molten explosives provided in this embodiment comprises a base 10, a three-axis module 20, a positive pressure unit 30, a docking unit 40, a jacket assembly 50, a touch screen 60, and a transfer fixture 70. The molten explosive product 80 is placed into the fixture from the previous process, and after loading is complete, it is transferred to this workstation. Each jacket assembly 50 is manually fixed to the product surface. According to the product model, corresponding control parameters are set on the touch screen 60. After the product is placed, the equipment start button is pressed. These control parameters may include the dimensions corresponding to the model of the molten explosive product 80, guiding the three-axis module 20 to adjust the position of the positive pressure unit 30. The control parameters also include a target solidification method, which may include any one of positive pressure solidification, water bath solidification, or a combination of positive pressure and water bath solidification. This allows the control unit to control the corresponding equipment to perform the appropriate operation based on the determined target solidification method.

[0027] The three-axis module 20 automatically adjusts the X and Y axis positions to align the positive pressure unit 30 with the molten charge product 80. The positive pressure unit 30 automatically adjusts its height along the Z axis, achieving automatic docking with the molten charge product 80. The docking unit 40 consists of self-sealing quick-connect couplings at both ends for automatic docking. This completes the preparation work for the molten charge solidification process. The heat source docking of the jacket and riser uses self-sealing quick-connect couplings, providing rapid and automatic docking. Excess channels are also provided to increase the number of water bath jackets and achieve precise temperature control in more areas.

[0028] An external positive pressure device is connected to the positive pressure unit 30 via a pipe, and an external hot water circulation temperature control device is connected to the docking unit 40 via a pipe. When a composite solidification method is adopted, the positive pressure device and the water circulation temperature control device work when the cast charge begins to solidify, realizing a composite solidification method of positive pressure on the cast charge and cooling of the water bath jacket control area. Alternatively, water circulation temperature control can be used alone to achieve a solidification method of cooling the water bath jacket control area.

[0029] In summary, the casting and cooling device for molten explosives provided in this application, through multi-layer independent water bath jackets and an automatically docking pressure docking device, realizes the segmented control reduction and positive pressure sequential solidification function of the casting process. This makes the solidification process more stable, further reducing the occurrence of defects such as porosity, cracks, and bottom gaps. At the same time, it reserves more space for segment jackets, which can increase the number of water bath jackets to achieve more precise regional temperature control, thereby better controlling the solidification process and improving product quality.
