Description

Technical Field

[0001] The invention relates to the technical field of perforating bullet compressed charge forming equipment, in particular to a perforating bullet compressed charge device for preventing explosives from scattering. Background Art

[0002] During the automated production of perforating charges, the charge pressing device, under the pressure of the punch, often squeezes explosives out of the interface between the bullet mouth and the centering sleeve, forming a ring-shaped explosive pad. After the perforating charge is formed, the traditional process involves removing the punch, the centering sleeve, and then the perforating charge. During this process, the explosive pad adhered to the centering sleeve and the bullet mouth will randomly fall off and scatter on the mold work surface. As production continues, the explosive pad accumulates, posing a safety hazard, increasing production risks and requiring machine downtime for cleaning, which in turn affects production efficiency. Therefore, we propose a device for preventing explosive scattering in perforating charge pressing. Summary of the Invention

Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] like Figure 1-5 As shown, a perforating bomb pressure charge prevention device for preventing explosives from scattering includes a hydraulic press, a middle mold 3 installed on the workbench 1 of the hydraulic press, a mechanical arm installed on one side of the hydraulic press, a connecting tube 2 installed at the end of the mechanical arm, a lifting unit 15 and a controller, characterized in that: the middle mold 3 is a hollow structure, the inner cavity of the middle mold 3 passes through the upper and lower ends of the middle mold 3, a base 5 is movably provided in the middle mold 3, a straightening sleeve 4 is inserted into the upper end of the middle mold 3, a cover plate 6 is fixedly installed on the end of the connecting tube 2 away from the mechanical arm, a connecting ring 7 is fixedly installed on the end of the cover plate 6 away from the connecting tube 2, a bottom plate 8 is fixedly installed on the end of the connecting ring 7 away from the cover plate 6, an opening and closing structure 9 is provided in the cavity surrounded by the cover plate 6, the connecting ring 7 and the bottom plate 8, the outer side surface of the opening and closing structure 9 movably passes through the outer facade of the connecting ring 7 and extends to the outside of the connecting ring 7, a clamping claw 10 is fixedly installed on the outside of one end of the opening and closing structure 9, and the clamping claw 10 is located on the side of the bottom plate 8 away from the connecting ring 7. The lifting unit 15 includes a lifting hydraulic cylinder 151 and a mounting frame 152. The lifting hydraulic cylinder 151 is fixedly mounted on one end of the mounting frame 152. The output end of the lifting hydraulic cylinder 151 movably passes through the mounting frame 152 and the workbench 1 and is fixedly mounted with a top seat 153. The other end of the mounting frame 152 is fixedly mounted on the bottom end of the workbench 1 of the hydraulic press. The top seat 153 is connected to the base 5. A plurality of clamping claws 10 are provided and distributed in a circular array centered on the central axis of the connecting ring 7.

[0026] The above-mentioned perforating bullet pressing device for preventing explosives from scattering is used to press the perforating bullet 13 ( Figure 6 ) is taken out, and the centralizing sleeve 4 is taken out, and the centralizing sleeve 4 and the perforating bullet 13 are taken out successively, while preventing the medicinal pad 14 ( Figure 6 ) scattered.

[0027] When pressing explosives into the perforating bullet 13, the punch 16 ( Figure 6 ) is connected to the output end of the hydraulic press, and the hydraulic press pushes the punch 16 downward and passes through the inner hole of the straightening sleeve 4 to press the explosive in the perforating bullet 13 into shape; after the explosive is pressed and formed, the hydraulic press pulls up the punch 16, and the punch 16 is separated from the straightening sleeve 4 and moved above the straightening sleeve 4. Then, the robotic arm moves the connecting tube 2 and the structure connected to the connecting tube 2 to the straightening sleeve 4. At this time, the multiple clamping claws 10 are in an open state. Through the cooperation of the robotic arm and the opening and closing structure 9, the multiple clamping claws 10 clamp the straightening sleeve 4 and move the straightening sleeve 4 upward. At the same time, the lifting hydraulic cylinder 151 pushes out the top seat 153, so that the base 5, the perforating bullet 13, and the medicine pad 14 move upward synchronously. After a part of the perforating bullet 13 moves above the middle mold 3, the robotic arm controls The clamping claws 10 move downward, and the centering sleeve 4 moves into the space enclosed by the multiple clamping claws 10. The clamping claws 10 then continue to move downward, outside the perforating charge 13. The opening and closing mechanism 9 controls the clamping claws 10 to close, clamping the multiple clamping claws 10 to hold the perforating charge 13. The centering sleeve 4, the charge pad 14, and the perforating charge 13 are then moved away from the center mold 3 by a mechanical arm. The opening and closing mechanism 9 then opens, opening the clamping claws 10 to a position just wide enough to release the perforating charge 13. At this point, the centering sleeve 4 remains within the space enclosed by the multiple clamping claws 10. After the perforating charge 13 is released from the clamping claws 10, the lower end of the centering sleeve 4 subsequently moves downward to the outside of the clamping claws 10, facilitating subsequent cleaning and explosive removal operations. After cleaning, the centering sleeve 4 can be placed back into the center mold 3 for use. After the perforating bullet 13 is removed from the middle mold 3 , the lifting hydraulic cylinder 151 pulls back the base 5 to reset the base 5 .

[0028] As a further illustration of the above scheme, Figure 3 and Figure 4As shown, the opening and closing structure 9 includes an inner meshing gear ring 91 and a groove frame 95. The inner meshing gear ring 91 is movably engaged with the upper end of the connecting ring 7 and is in movably contact with the upper end of the cover plate 6. The inner side of the inner meshing gear ring 91 is meshedly connected with a driving gear 92. There are multiple driving gears 92 and they are distributed in a ring array. The inner meshing gear ring 91 is transmission-connected to multiple driving gears 92. When one driving gear 92 is driven to rotate by an external power source, the driving gear 92 that is not driven by the external power source can be rotated synchronously by the rotation of the inner meshing gear ring 91. Connecting shafts 93 are inserted and fixedly installed on the multiple driving gears 92. A transmission gear 94 is fixedly installed on the side of the outer cylindrical surface of the multiple connecting shafts 93 away from the cover plate 6. There are multiple slot frames 95, and the number of slot frames 95 is consistent with the number of transmission gears 94. Racks 96 are fixedly installed in the grooves of multiple slot frames 95. Racks 96 are meshed with transmission gears 94. The rotation of transmission gear 94 can drive racks 96 to move, causing slot frames 95 to move. Slots 71 are provided on the outer surface of connecting ring 7. Slots 71 are provided in multiple numbers and are distributed in a circular array centered on the central axis of connecting ring 7. Multiple slot frames 95 are movably inserted into multiple slots 71 and can move within slots 71. Driven by transmission gear 94, racks 96 and slot frames 95 can be telescopically moved relative to connecting ring 7 through slots 71. Connecting shaft 93 is interlaced and movably connected with cover plate 6 and bottom plate 8. In one specific embodiment, there are four driving gears 92, connecting shaft 93, transmission gear 94, slot frames 95, and racks 96, and four slots 71 are provided.

[0029] It should be noted that a support tube 81 is fixedly installed on the middle part of one end of the base plate 8 facing the cover plate 6. The support tube 81 is fixedly connected to the cover plate 6, which can improve the connection strength and reduce the deformation of the cover plate 6 and the base plate 8 during use.

[0030] It should be further explained that the perforating charge compression device for preventing explosive scattering also includes a drive motor 21, which is fixedly mounted on the outer cylindrical surface of the connecting barrel 2. The output end of the drive motor 21 is drivingly connected to any one of a plurality of connecting shafts 93. The length of the connecting shaft 93 connected to the drive motor 21 is greater than the length of the connecting shaft 93 not connected to the drive motor 21, and the connection between the connecting shaft 93 and the output end of the drive motor 21 is achieved via a coupling. The forward and reverse rotation of the drive motor 21 (forward rotation is clockwise rotation, reverse rotation is counterclockwise rotation) drives the connecting shaft 93 forward and reverse, thereby causing the drive gear 92, the transmission gear 94, and the internal meshing ring gear 91 to rotate forward and reverse. During forward rotation, the transmission gear 94 cooperates with the rack 96 to push the slot frame 95 out of the connecting ring 7. During reverse rotation, the slot frame 95 is retracted into the connecting ring 7.

[0031] As a further illustration of the above scheme, Figure 5As shown, the number of clamping claws 10 is consistent with the number of slot frames 95; in one embodiment, the number of clamping claws 10 and the number of slot frames 95 are both four; the clamping claw 10 includes an arc-shaped clamping frame 101, a first clamping block 102 is fixedly mounted on the inner side of the clamping frame 101, a second clamping block 103 is fixedly mounted on the inner side of the first clamping block 102, and a transmission frame 104 is fixedly mounted on the outer side of the clamping frame 101, and the transmission frame 104 is fixedly connected to the slot frame 95; in one embodiment, the transmission frame 104 is detachably fixedly connected to the slot frame 95 by bolts. A guide rail 11 is fixedly mounted on one end of the bottom plate 8 away from the cover plate 6, and a slider 12 is slidably mounted on the guide rail 11. The slider 12 is fixedly mounted on the end surface of the clamping frame 101 facing the bottom plate 8. When the slot frame 95 performs telescopic movement relative to the connecting ring 7, that is, when the slot frame 95 extends relative to the connecting ring 7, the transmission frame 104 drives the clamping frame 101 to move outward, causing the clamping claw 10 to open. When the slot frame 95 retracts relative to the connecting ring 7, the transmission frame 104 drives the clamping frame 101 to move inward, causing the clamping claw 10 to close, thereby realizing the opening and closing of the clamping claw 10. When the clamping claw 10 opens and closes, the slider 12 slides on the guide rail 11, and the slider 12 cooperates with the guide rail 11 to make the clamping claw 10 slide stably on the outer side of the bottom plate 8, so that the slot frame 95 is not affected by the gravity of the clamping claw 10, and the slot frame 95 is prevented from bending.

[0032] It should be noted that the end of the bracket 101 away from the base plate 8, the end of the first clamping block 102 away from the base plate 8, and the end of the second clamping block 103 away from the base plate 8 are on the same end surface. The height of the first clamping block 102 is greater than that of the second clamping block 103, forming a stepped structure. The straightening sleeve 4 has a T-shaped structure and cooperates with the second clamping block 103. Multiple clamping claws 10 cooperate to clamp the straightening sleeve 4 and the perforating charge 13. When clamping the straightening sleeve 4, the inner surface of the second clamping block 103 contacts the large end of the straightening sleeve 4. When clamping the perforating charge 13, the inner surface of the second clamping block 103 contacts the outer wall of the perforating charge 13. When the perforating charge 13 is separated from the clamping claws 10 but the straightening sleeve 4 has not yet separated from the clamping claws 10, the large end of the straightening sleeve 4 contacts the end of the second clamping block 103 facing the base plate 8, and the end surface of the small end of the straightening sleeve 4 is located outside the clamping claws 10.

[0033] It should be noted that the hydraulic press, the drive motor 21 , the lifting hydraulic cylinder 151 , and the robotic arm are all controlled by a controller.

[0034] It should be noted that, in actual operation, the structure for simultaneously driving the opening and closing of multiple clamping claws 10 is not limited to the above embodiment and can be replaced by other structures.

[0035] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
