Description

Technical Field

[0001] This invention relates to the field of explosive composite plate processing equipment, specifically to an explosive limiting frame for explosive welding of composite plates. Background Technology

[0002] The production method of explosively welded composite plates involves placing a prepared composite plate on a substrate, with the composite plate and substrate supported by a gap support plate. A layer of explosive is then laid on the composite plate. The instantaneous ultra-high pressure and ultra-high speed impact energy generated during the explosion of the explosive achieves solid-state metallurgical bonding between the metal layers. During the laying of the explosive, a limiting frame needs to be placed at the edge of the composite plate to prevent the explosive from scattering.

[0003] Existing explosive restraint frames are all made of ordinary cardboard or wood panels that have been cut and spliced ​​together, and they have the following defects when used:

[0004] (1) Studies have shown that, in order to obtain the ideal microwave-like interface of the composite plate, laying explosives evenly with equal thickness is not the optimal method of explosive placement. Instead, seeking an appropriate tilt angle for the explosives and gradually reducing the explosive thickness along the detonation direction is the optimal method. This is because after forming the tilt angle, the explosive load at each point of the composite plate remains basically unchanged, avoiding the large wave-like bond with defects such as gaps and voids caused by the melting of metal due to excessive explosive charge. This controls the collision speed between the substrate and the composite plate, improves the bonding strength of the composite plate, and achieves the ideal goal of a micro-wave-like bond across the entire interface of the composite plate. However, the existing limiting frame structure does not have the function of assisting the explosive loading operation, which is not conducive to forming the tilt angle for the explosives.

[0005] (2) After the existing limit frame is placed, a gap will be generated between its bottom surface and the surface of the cover plate, and the phenomenon of explosive powder dripping will still occur. The existing solutions are mostly to seal it with tape, which is obviously very troublesome. Summary of the Invention

[0006] The purpose of this invention is to provide an explosive limiting frame for explosive welding of composite plates, which solves the problems of existing explosive limiting frames being unfavorable for forming the charging tilt angle and the easy appearance of gaps between the bottom surface and the surface of the composite plate.

[0007] The present invention achieves the above objectives through the following technical solutions:

[0008] A limit frame for explosive welding of composite plates includes a frame frame and a charging angle limiting frame. The charging angle limiting frame includes a mounting component detachably connected to the frame frame, a vertical telescopic component on the mounting component, a horizontal rotating component at the bottom end of the vertical telescopic component, and a swing rod hinged to the bottom end of the horizontal rotating component. The length of the swing rod is freely adjustable. The swing rod changes its tilt angle by swinging along a vertical plane, and the swing rod is provided with a locking component to lock the tilt angle.

[0009] The top surface of the frame has an annular groove, and a movable block is movably installed in the annular groove. A connecting plate is provided on the movable block, and the connecting plate extends to the inner side wall of the frame. A vertical slide rail is provided on the connecting plate, and the free end of the swing rod is slidably connected to the slide rail.

[0010] A further improvement is that the mounting component includes a mounting plate, a crossbar rotatably disposed on the top of the mounting plate, and a slider slidably disposed on the crossbar. A fixing pin is provided on the crossbar to limit the rotation of the crossbar, and a fixing pin is provided on the slider to limit the sliding of the slider.

[0011] A further improvement is that each side of the frame is provided with a plug-in slot, and the side of the mounting plate is inserted into the plug-in slot to realize the detachable connection between the mounting component and the frame. The length of the crossbar is greater than 1 / 2 of the maximum side length of the frame.

[0012] A further improvement is that the vertical telescopic component consists of a rotating cylinder and a screw threaded inside the rotating cylinder. The extension and retraction of the vertical telescopic component is achieved by rotating the rotating cylinder, and a fixing pin is provided on the rotating cylinder to limit the rotation of the rotating cylinder.

[0013] A further improvement is that the horizontal rotating component is composed of two disks that can rotate freely relative to each other.

[0014] A further improvement is that the locking component includes an extension rod, a threaded sleeve, and a threaded pull rod. The extension rod is located directly above the swing position of the swing rod. The threaded sleeve is hinged to the extension rod through its outer wall. The pull rod is threaded through the threaded sleeve, and the bottom end of the pull rod is hinged to the swing rod. The top end of the pull rod is provided with a handle. By rotating the pull rod through the handle, the tilt angle of the swing rod can be adjusted and then locked.

[0015] A further improvement is that the swing arm is composed of multiple hollow rods that are movably connected.

[0016] A further improvement is that the bottom surface of the frame is provided with a ring-shaped protrusion, the ring-shaped protrusion is matched with the shape of the ring groove, and a sealing sponge strip is detachably sleeved on the outside of the ring-shaped protrusion.

[0017] The beneficial effects of this invention are as follows:

[0018] (1) The explosive limiting frame is equipped with a loading angle limiting frame. When laying explosives, the tilt angle of its swing rod can be adjusted and the ring rotation can provide a reference for loading operation, adjust the height of the loading surface, and thus form a precise and appropriate loading tilt angle, which helps to obtain an ideal composite plate microwave-shaped bonding interface.

[0019] (2) The explosive limiting frame can be set to any shape, including rectangle, circle, etc., and by adjusting the mounting parts, the highest point of the swing rod can be located above any position in the frame area, thus making the explosive limiting frame applicable to the explosive welding process at any detonation point.

[0020] (3) The explosive angle limiting frame in the explosive limiting frame can be disassembled and reused to reduce costs, while the frame can be stacked to meet the requirements of laying explosives with higher charge.

[0021] (4) The bottom surface of the frame frame of the explosive limiting frame is equipped with a sealing sponge strip, so that there will be no gaps after the frame frame is placed on the cover plate, and there is no need to perform operations such as sealing with tape.

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Combination Figures 1 to 4 As shown, an explosive limiting frame for composite plate explosive welding includes a frame frame 1 and an explosive angle limiting frame. The explosive angle limiting frame includes a mounting component 2 detachably connected to the frame frame 1, a vertical telescopic component 3 on the mounting component 2, a horizontal rotating component 4 at the bottom of the vertical telescopic component 3, and a swing rod 5 hinged to the bottom of the horizontal rotating component 4. The length of the swing rod 5 is freely adjustable. The swing rod 5 changes its tilt angle by swinging along a vertical plane, and a locking component 6 is provided on the swing rod 5 to lock the tilt angle. A ring groove 7 is formed on the top surface of the frame frame 1. A moving block 8 is movably provided in the ring groove 7. A connecting plate 9 is provided on the moving block 8. The connecting plate 9 extends to the inner side wall of the frame frame 1. The connecting plate 9 is sheet-shaped and has a vertical slide rail 10. The free end of the swing rod 5 is slidably connected to the slide rail 10.

[0030] When the swing rod 5 swings along the vertical plane, the free end of the swing rod 5 will slide up and down in the slide rail 10. After the tilt angle of the swing rod 5 is fixed, the swing rod 5 is rotated horizontally. The free end of the swing rod 5 will also slide up and down in the slide rail 10 according to the shape of the frame 1 (the distance from the highest point of the swing rod is different). At the same time, the swing rod 5 will automatically extend and retract. In this way, no matter what shape the frame 1 is, it can ensure that the swing rod 5 can rotate horizontally stably at a fixed tilt angle.

[0031] In this invention, the highest point of the swing rod 5 can be adjusted via the mounting component 2, and the highest point of the swing rod 5 must cover any position of the entire frame 1. This facilitates the installation position of the corresponding detonator, making the explosive limiting frame suitable for explosive welding processes at any detonation point. Specifically, the mounting component 2 can be composed of different structures, for example, it can be a two-dimensional linear module composed of an X-axis and a Y-axis.

[0032] This invention details one embodiment of the mounting component 2: it includes a mounting plate 201, a crossbar 202 rotatably mounted on the top of the mounting plate 201, and a slider 203 slidably mounted on the crossbar 202. A fixing pin is provided on the crossbar 202 to restrict its rotation, and a fixing pin is provided on the slider 203 to restrict its sliding. Preferably, different sides of the frame 1 are provided with insertion slots 11. The side of the mounting plate 201 is inserted into the insertion slots 11, achieving a detachable connection between the mounting component 2 and the frame 1. The length of the crossbar 202 is greater than half the maximum side length of the frame 1. For example, if the frame 1 is rectangular and the length of the crossbar 202 is half the frame length, by selecting different insertion slots 11 on different sides, and by rotating the crossbar 202 and sliding the slider 203, the highest point of the swing rod 5 can cover any position of the entire frame 1; furthermore, the mounting component 2 does not affect the horizontal rotation of the swing rod 5.

[0033] In this invention, the vertical telescopic component 3 functions to adjust the overall height of the swing rod 5 to accommodate different dosages. It consists of a rotating cylinder 301 and a screw 302 threadedly connected within the rotating cylinder 301. The vertical telescopic component 3 extends and retracts by rotating the rotating cylinder 301. A fixing pin is provided on the rotating cylinder 301 to limit its rotation. The rotating cylinder 301 and the screw 302 are connected by a fine-pitch thread, facilitating more precise adjustments. The horizontal rotating component 4 allows the swing rod 5 to rotate freely. It consists of two freely rotatable discs connected together.

[0034] In this invention, the locking component 6 includes an extension rod 601, a threaded sleeve 602, and a threaded pull rod 603. The extension rod 601 is located directly above the swing position of the swing rod 5. The threaded sleeve 602 is hinged to the extension rod 601 through its outer wall. The pull rod 603 is threaded through the threaded sleeve 602, and its bottom end is hinged to the swing rod 5. A handle 604 is provided at the top of the pull rod 603. By rotating the pull rod 603 through the handle 604, the pull rod 603 moves up and down along the threaded sleeve 602. The hinged arrangement at both ends of the pull rod 603 also allows the angle of the pull rod 603 to change during the movement, thereby achieving locking after adjusting the tilt angle of the swing rod 5. Of course, the locking component 6 can also adopt other structures, such as directly setting a clamping nut at the hinged position at the highest point of the swing rod 5.

[0035] In this invention, the swing rod 5 is composed of multiple hollow rods that are movably connected. The wall thickness of each hollow rod is small, so that the overall diameter of the swing rod 5 does not change much, which is beneficial to the reference accuracy during loading.

[0036] In this invention, the bottom surface of the frame 1 is provided with a ring-shaped protrusion (not shown in the figure), which matches the shape of the ring groove 7. This allows for the stacking of two or more frame 1s during explosive welding processes with large explosive charges, increasing the limiting height. The stacked structure is as follows: Figure 5 As shown; in addition, a sealing sponge strip 12 is detachably sleeved on the outside of the annular protrusion. After the frame 1 is placed on the cover plate, the elastic adjustment of the sealing sponge strip 12 ensures that there will be no gap between the bottom surface of the frame 1 and the surface of the cover plate, thus eliminating the need for sealing with tape or other operations.

[0037] It should be noted that the frame 1 of the explosive limiting frame can also be made of materials such as wood, cardboard, or fiber, while the explosive angle limiting frame can be made of materials such as metal alloy, rubber, or hard plastic, since it does not require an accompanying detonation process and can be reused.

[0038] The usage process of this invention is as follows: Figure 6 As shown, first select a fine sand foundation, place the base plate stably on the foundation, then place several gap supports on the surface of the base plate, and place the cover plate through the gap supports. Then place the explosive limiting frame of the present invention on the surface of the cover plate, aligning the frame 1 with the edge of the cover plate. Next, determine the detonation point position, and move the highest point of the swing rod 5 directly above the detonation point position using the mounting component 2. Then adjust the vertical telescopic component 3 according to the charge amount to make the swing rod 5 at a suitable height. Then adjust the locking component 6 according to the required charge tilt angle to make the tilt angle of the swing rod 5 consistent with the required charge tilt angle. At this point, the charge preparation work is completed. During loading, the explosive is laid within the frame 1. When the charge is approximately reached, the horizontal rotating component 4 horizontally rotates the swing rod 5. By observing the gap between the bottom surface of the swing rod 5 and the surface of the explosive, the appropriate thickness is determined at all positions. The swing rod can also sweep away explosives in areas with excessive thickness, ultimately ensuring that the surface of the explosive and the bottom surface of the swing rod 5 are in precise contact. This creates a precise and appropriate loading tilt angle, contributing to the ideal microwave-like interface of the composite plate. During the horizontal rotation of the swing rod 5, its free end slides up and down within the slide rail 10 for adjustment. Simultaneously, the swing rod 5 itself automatically extends and retracts. Therefore, regardless of the shape of the frame 1, the swing rod 5 can be stably rotated horizontally at a fixed tilt angle, ensuring that the entire loading area meets this tilt angle. After loading is complete, the loading angle limiting frame can be removed, and the detonator can be installed for detonation.

[0039] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
