Description

Technical Field

[0001] This utility model relates to waste ammunition cutting and processing technology, and in particular to an automatic follow-up adjustment device for a hydraulic cutting nozzle for waste ammunition. This device is used to improve the stability and cutting efficiency of the nozzle during the hydraulic cutting process, and to ensure that the nozzle maintains the optimal distance from the surface of the waste ammunition, thereby achieving a high-efficiency and uniform cutting effect. Background Technology

[0002] The cutting and disposal of obsolete ammunition is a highly specialized technical field. Obsolete ammunition may include expired, ineffective, or damaged ammunition. Cutting precision and efficiency are crucial in the processing of these ammunition. Hydraulic cutting technology, due to its high efficiency, safety, and applicability to various materials, is widely used in the cutting of obsolete ammunition. However, because obsolete ammunition typically consists of a near-cylindrical + near-conical shape with constantly changing curvature, hydraulic cutting presents several challenges:

[0003] (1) The distance between the nozzle and the surface of the ammunition is uneven. If the nozzle only moves in a simple planar straight line, it cannot adapt to the changes in surface curvature. The distance between the nozzle and the surface of the ammunition is constantly changing, which may lead to uneven concentration of water flow and abrasive during the cutting process, thus affecting the cutting effect.

[0004] (2) The cutting effect is unstable. Due to the uneven distance between the nozzle and the waste ammunition, the abrasive may be unevenly distributed during cutting, some areas may not be cut completely, and some areas may be excessively worn, wasting unnecessary abrasive. At the same time, it may also cause the cut surface to be uneven.

[0005] (3) In existing water-jet cutting equipment, most of them use fixed nozzles or manual adjustment. This design cannot be adjusted in real time according to the different shapes of the waste ammunition, resulting in low cutting efficiency. Especially when facing a row of waste ammunition, the nozzle is difficult to maintain the best cutting angle and distance, which delays the cutting process and increases the operation time.

[0006] (4) Due to the constant change in the distance between the nozzle and the surface of the waste ammunition during the water jet cutting process, the abrasive distribution is uneven, and the abrasive consumption is relatively large in some areas, resulting in unnecessary abrasive waste. At the same time, due to the uneven cutting surface, multiple cuts may be required, which further aggravates the consumption of abrasive.

[0007] Therefore, designing a nozzle-following adjustment device based on the surface curvature of the ammunition, enabling the nozzle to automatically adjust its position according to changes in the surface of the waste ammunition, maintaining the optimal cutting distance, and improving cutting accuracy and efficiency, has become a core problem that waterjet cutting technology urgently needs to solve. By improving the adaptability of the nozzle to the surface of the waste ammunition, not only can the waste of abrasive during the cutting process be effectively reduced, but the overall efficiency of the cutting operation can also be improved, providing a more efficient solution for the safe disposal of waste ammunition. Utility Model Content

[0008] The technical problem this invention aims to solve is to address the aforementioned deficiencies in existing technologies by providing an automatic follow-up adjustment device for the nozzle of a hydraulic cutting machine for waste ammunition. This device improves the adaptability between the nozzle and the surface of the waste ammunition during hydraulic cutting. The device achieves automatic adjustment of the distance between the nozzle and the ammunition surface through a purely mechanical structure, ensuring that the nozzle maintains the optimal working distance from the surface of the waste ammunition (especially the conical portion) during cutting. Its main advantages include improved cutting accuracy and efficiency, reduced abrasive waste, simplified structure, and lower costs. The device requires no complex electronic systems, employs a simple mechanical design, and features high stability, reliability, and ease of maintenance. It can adapt to waste ammunition of different shapes and sizes and is suitable for widespread application in the processing and disposal of waste ammunition. By automatically adjusting the contact angle between the nozzle and the surface, the device effectively improves the efficiency of hydraulic cutting, reduces manual intervention, and ensures efficient and safe cutting of waste ammunition.

[0009] According to this utility model, an automatic follow-up adjustment device for a hydraulic cutting nozzle of waste ammunition is provided, comprising: a spray module, a follow-up adjustment module, a power plate, a guide rod, and a lifting plate; wherein the spray module and the guide rod are fixed on the lifting plate, and the follow-up adjustment module passes through the power plate and the lifting plate.

[0010] Preferably, the power plate moves horizontally from the spray module to the follow-up adjustment module to pull the entire automatic follow-up adjustment device for waste ammunition hydraulic cutting nozzles to move in a straight line, so that the waste ammunition below the automatic follow-up adjustment device for waste ammunition hydraulic cutting nozzles successively contacts the follow-up adjustment module and the spray module. At the same time, the follow-up adjustment module adjusts the height of the water jet pipe of the spray module according to the height of the contacted waste ammunition through the lifting and lowering of the lifting plate.

[0011] Preferably, the spraying module includes: a high-pressure hose, a locking conical cap, a water jet sand pipe, fixing bolts, and a conical fixing seat; wherein the conical fixing seat is fixed to the lifting plate by bolts, and the high-pressure hose is connected to the water jet sand pipe to guide the high-pressure water-sand mixture into the water jet sand pipe, and the water jet sand pipe modulates it to form a high-speed two-phase jet to cut the waste ammunition.

[0012] Preferably, the water jet abrasive tube can slide up and down within the conical fixing seat to adjust the distance between the water jet abrasive tube and the surface of the waste ammunition. Tightening the locking conical pressure cap is used to fix the water jet abrasive tube in place with the threaded connection between the locking cap and the conical fixing seat after the distance is adjusted.

[0013] Preferably, the follow-up adjustment module includes: a limit nut, a central rod, a fixing bolt, an upper guide sleeve, a spring, a lower guide sleeve, a roller, and a rotating shaft; wherein the upper and lower guide sleeves constitute the sleeve mechanism of the spring, and the central rod serves as the core shaft mechanism of the spring to prevent the spring from becoming unstable during compression; the upper guide sleeve is fixed to the power plate by the fixing bolt, and the lower guide sleeve is screwed onto the central rod by threads, and the limit nut is screwed onto the central rod by threads; the roller forms a rotating pair with the central rod through the rotating shaft; the central rod is provided with a step for locking onto the lower edge of the lifting plate.

[0014] Preferably, during the hydraulic cutting of waste ammunition, the roller first contacts the surface of the waste ammunition. At this time, the water jet abrasive tube is at the lowest position. As the power plate continues to move to the right, the roller rolls along the surface of the waste ammunition, pushing the center rod upward and compressing the spring. At the same time, the step of the center rod in contact with the lower edge of the lifting plate pushes the lifting plate upward, and finally pushes the water jet abrasive tube upward.

[0015] Preferably, during the hydraulic cutting of waste ammunition, the upward movement rate of the water jet abrasive tube completely follows the upward movement rate of the roller on the surface of the waste ammunition, thus realizing that the distance between the water jet abrasive tube and the waste ammunition can be adjusted in real time to completely follow the curvature of the waste ammunition's shape.

It aims to improve the adaptability between the nozzle and the surface of the discarded ammunition during hydraulic cutting, particularly addressing changes in the surface curvature. Employing a purely mechanical structure, the device utilizes components such as a jetting module, a follow-up adjustment module, and a lifting plate to automatically adjust the distance between the nozzle and the surface of the discarded ammunition. The nozzle automatically follows the shape changes of the discarded ammunition, ensuring that the optimal cutting angle and distance are always maintained, thereby improving cutting accuracy and efficiency. The device uses a high-pressure water-abrasive mixture to form a high-speed two-phase jet for precise cutting of the discarded ammunition. This device has a simple structure, requires no complex electronic systems, possesses high stability and reliability, and effectively reduces abrasive waste and maintenance costs.

[0029] In summary, this invention provides an automatic follow-up adjustment device for a hydraulic cutting nozzle used for discarded ammunition. It aims to improve the adaptability between the nozzle and the surface of the discarded ammunition during hydraulic cutting, particularly addressing changes in the surface curvature. Employing a purely mechanical structure, the device utilizes components such as a jetting module, a follow-up adjustment module, and a lifting plate to automatically adjust the distance between the nozzle and the surface of the discarded ammunition. The nozzle automatically follows the shape changes of the discarded ammunition, ensuring that the optimal cutting angle and distance are always maintained, thereby improving cutting accuracy and efficiency. The device uses a high-pressure water-abrasive mixture to form a high-speed two-phase jet for precise cutting of the discarded ammunition. This device has a simple structure, requires no complex electronic systems, possesses high stability and reliability, and effectively reduces abrasive waste and maintenance costs. It is suitable for cutting discarded ammunition of various shapes and sizes.

[0030] Figure 1 A schematic diagram illustrating the overall structural composition of the automatic follow-up adjustment device for the hydraulic cutting nozzle of waste ammunition according to a preferred embodiment of the present invention is shown. Figure 1As shown, the automatic follow-up adjustment device for the hydraulic cutting nozzle of waste ammunition according to a preferred embodiment of the present invention includes: a spray module 1, a follow-up adjustment module 2, a power plate 3, a guide rod 4, and a lifting plate 5; wherein the spray module 1 and the guide rod 4 are fixed on the lifting plate 5 (for example by bolts or other appropriate means), and the follow-up adjustment module 2 passes through the power plate 3 and the lifting plate 5.

[0031] Furthermore, the power plate 3 performs horizontal movement in the direction from the spray module 1 to the follow-up adjustment module 2 to pull the entire automatic follow-up adjustment device for waste ammunition water cutting nozzle to move in a straight line, so that the waste ammunition 6 below the automatic follow-up adjustment device for waste ammunition water cutting nozzle successively contacts the follow-up adjustment module 2 and the spray module 1. At the same time, the follow-up adjustment module 2 adjusts the height of the water jet pipe of the spray module 1 according to the height of the contacted waste ammunition 6 via the lifting plate 5.

[0032] Preferably, the spray module 1 includes: a high-pressure hose 1-1, a locking conical cap 1-2, a water jet abrasive tube 1-3, a fixing bolt 1-5, and a conical fixing seat 1-6; wherein the conical fixing seat 1-6 is fixed to the lifting plate 5 by the bolt 1-5, the high-pressure hose 1-1 is connected to the water jet abrasive tube 1-3, and the high-pressure water-sand mixture is guided into the water jet abrasive tube 1-3, and the water jet abrasive tube 1-3 modulates it to form a high-speed two-phase jet 1-4 to cut the waste ammunition 6; the water jet abrasive tube 1-3 can slide up and down in the conical fixing seat 1-6, thereby adjusting the distance between the water jet abrasive tube 1-3 and the surface of the waste ammunition, and tightening the locking conical cap 1-2 is used to fix the thread between the water jet abrasive tube 1-3 and the conical fixing seat 1-6 after the distance is adjusted (to a suitable distance), thus fixing the water jet abrasive tube 1-3 and preventing it from loosening during the spraying process.

[0033] Preferably, the follow-up adjustment module 2 includes: a limiting nut 2-1, a central rod 2-2, a fixing bolt 2-3, an upper guide sleeve 2-4, a spring 2-5, a lower guide sleeve 2-6, a roller 2-7, and a rotating shaft 2-8. The upper guide sleeve 2-4 and the lower guide sleeve 2-6 form the sleeve mechanism of the spring 2-5, and the central rod 2-2 serves as the spindle mechanism of the spring 2-5 to prevent instability during compression. The upper guide sleeve 2-4 is fixed to the power plate 3 by the fixing bolt 2-3, and the lower guide sleeve 2-6 is threaded onto the central rod 2-2. The limiting nut 2-1 is threaded onto the central rod 2-2. The roller 2-7 forms a rotating pair with the central rod 2-2 via the rotating shaft 2-8. The central rod 2-2 is provided with a step for engaging with the lower edge of the lifting plate 5. As described later, the lifting plate automatically adjusts the contact distance between the water jet abrasive pipe and the surface of the waste ammunition by cooperating with the step on the central rod.

[0034] More specifically, see Figures 1-4A typical implementation is as follows: During the hydraulic cutting of waste ammunition, the power plate 3 provides the power for the entire device to move to the right. During the movement, the roller 2-7 first contacts the surface of the waste ammunition 6. At this time, the water jet abrasive tube 1-3 is at the lowest position. As the power plate 3 continues to move to the right, the roller 2-7 will roll along the surface of the waste ammunition 6, thereby pushing the central rod 2-2 to move upward, and then compressing the spring 2-5. During this process, the step of the central rod 2-2 that contacts the lower edge of the lifting plate 5 pushes the lifting plate 5 to move upward. Since the water jet abrasive tube 1-3 is rigidly connected to the lifting plate 5, it ultimately pushes the water jet abrasive tube 1-3 to move upward.

[0035] During this process, the upward movement rate of the water jet abrasive tube 1-3 perfectly matches the upward movement rate of the roller 2-7 on the surface of the waste ammunition 6. This ensures that the distance between the water jet abrasive tube 1-3 and the waste ammunition 6 is adjusted in real-time to perfectly follow the curvature of the waste ammunition 6. Simultaneously, the high-pressure hose 1-1 guides the high-pressure water-sand mixture into the water jet abrasive tube 1-3, where it is modulated to form a high-speed two-phase jet 1-4, cutting the waste ammunition. The entire cutting process is completed when the roller 2-7 passes through a row of side-by-side waste ammunition.

[0036] The beneficial effects of this utility model include at least the following aspects:

[0037] (1) Improve cutting accuracy: The nozzle follow-up device automatically adjusts the distance between the nozzle and the surface of the waste ammunition to ensure the optimal cutting distance and improve cutting accuracy.

[0038] (2) Improve cutting efficiency: By automatically adjusting the nozzle position, manual adjustment is reduced, cutting speed is increased, and the cutting process is optimized.

[0039] (3) Reduce abrasive waste: Dynamically adjust the distance between the nozzle and the waste ammunition to ensure effective use of abrasive and reduce waste.

[0040] (4) Simple structure and easy maintenance: The pure mechanical structure reduces the complexity of the equipment and makes it easy to maintain and replace parts.

[0041] Furthermore, it should be noted that, unless otherwise specified, the terms "first," "second," "third," etc., in the specification are used only to distinguish the various components, elements, and steps in the specification, and are not used to indicate the logical or sequential relationships between the various components, elements, and steps.

[0042] It is understood that although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention.
