Description

Technical Field

[0001] The invention relates to the technical field of explosive tool production, in particular to an oil press for suppressing earthquake source charge column explosive tools. Background Art

[0002] It is well known that detonators cannot directly detonate the relatively insensitive main charge filled in the plastic source charge column. Therefore, in order to ensure the safe and effective blasting, a detonator must be installed in the source charge column to ensure the single-shot detonation rate and the reliability of explosion transmission. The detonator is generally pressed and formed with TNT (trinitrotoluene) or RDX (trimethylene trinitramine) as raw materials. Because the raw materials are dangerous and explosive, in order to prevent the explosion of the detonator during the pressing process, resulting in casualties, the pressing process must be carried out in an explosion-proof room.

[0003] The traditional detonator suppression technology is carried out in the explosion-proof room, and the finished product removal, raw material filling, and mold core assembly are carried out in the operation room. It does not require the carriage to run back and forth. In addition, the hydraulic press needs to be idle for a long time during the period of finished product removal, raw material filling, and mold core assembly. Therefore, there is a problem of low production efficiency.

[0004] Therefore, it is very necessary to design a suppression device that can speed up the loading of raw materials and assembly of models, and then improve the production efficiency of detonators in order to improve enterprise benefits. Summary of the invention

[0023] The jacking plate assembly 2-4 includes a jacking plate bottom plate 2-4-1 fixedly mounted on the upper surface of the jacking slider 2-3, and a jacking plate base 2-4-6 is arranged on the upper surface of the jacking plate bottom plate 2-4-1; and a jacking plate 2-4-7 is fixedly mounted on the upper surface of the jacking plate base 2-4-6.

[0024] The surface of the top-lifting plate 2-4-7 is invertedly mounted with a plurality of C-shaped card plates 2-4-2; the plurality of card plates 2-4-2 are divided into two groups, dynamic and static, and are arranged at intervals, the dynamic group card plates 2-4-2 are slidably mounted on the top-lifting plate 2-4-7, and the static group card plates 2-4-2 are fixedly mounted on the top-lifting plate 2-4-7; The two sides of the top boosting plate 2-4-7 are also fixedly installed with a card opening and closing cylinder 2-4-5 on the top boosting plate base 2-4-6, and the output end of the card opening and closing cylinder 2-4-5 is fixedly installed with a guide rod 2-4-3, and the guide rod 2-4-3 passes through the two sides of the card plate 2-4-2, is slidably connected with the static group card plate 2-4-2, and is fixedly connected with the dynamic group card plate 2-4-2; the two adjacent card plates 2-4-2 can be relatively close to each other under the push and pull of the card opening and closing cylinder 2-4-5 and form a closed annular card hole; the card hole matches the annular groove at the lower end of the mold rod 2-5-1.

[0025] A plurality of limit columns 2-4-4 are fixedly installed on the upper surface of the top plate of the lifting pressure plate 2-4-7, and the upper ends of the limit columns 2-4-4 pass through the mold closing slide 2-6 and are slidably connected to the mold closing slide 2-6; a limit plate 2-9 is fixedly installed on the lower surface of the upper crossbeam 2-10 corresponding to the limit columns 2-4-4.

[0026] The hydraulic press 2 is placed in the operating room to complete the pressing process of the detonator. The operating room is surrounded by walls 3 to form a closed rectangular space, and the walls 3 are provided with a raw material transfer window explosion-proof door and a finished product transfer window explosion-proof door 1 for raw material input and finished product output.

[0027] A push plate 2-7-6 is installed between the two L-shaped brackets at one end close to the mold assembly 2-5, and a brush is installed below the push plate 2-7-6.

[0028] Open the explosion-proof door of the raw material transfer window on the wall 3, so that the feeding mechanism installed in the operation room extends into the explosion-proof room. Figure 4As shown, at this time, the rodless coupling cylinder 2-7-2 in the feeding assembly pushes the L-shaped bracket to slide outward along the linear guide rail 2-7-5, driving the material cup 2-7-3 fixed frame installed above the two L-shaped brackets and the multiple material cups 2-7-3 fixedly set above the material cup 2-7-3 fixed frame to be synchronously exposed on one side of the hydraulic press 2, so that the space above the material cup 2-7-3 is exposed, which is convenient for the feeding mechanism to pour the measured raw materials, i.e., TNT (trinitrotoluene) or RDX (trimethylene trinitramine) into the material cup 2-7-3. It should be noted that the above-mentioned feeding mechanism can be any known device or structure that can realize the quantitative supply of the above-mentioned raw materials, such as a robotic arm, a conveyor belt, etc., and its specific structure and feeding method are not described in detail here.

[0029] At this time, since the telescopic end of the discharge cylinder 2-7-7 is in the initial contracted state, it will drive the swing arm 2-7-4 to press down synchronously, pressing the sealing ball 2-7-8 in the material cup 2-7-3 to the lower end opening of the material cup 2-7-3, so as to seal the material cup 2-7-3. The blocked material cup 2-7-3 becomes a container for holding raw materials, and is driven by the rodless coupling cylinder 2-7-2 again to move to the top of the mold sleeve 2-5-3 until the lower end openings of the multiple material cups 2-7-3 correspond to the upper end openings of the multiple mold sleeves 2-5-3, thereby completing the transportation of the raw materials.

[0030] Then the telescopic end of the discharge cylinder 2-7-7 begins to extend, driving the swing arm 2-7-4 to move upward synchronously, and the upward swing arm 2-7-4 will drag the blocking ball to move upward synchronously, releasing the blocking of the material cup 2-7-3. As a result, the raw materials in the material cup 2-7-3 will slide down under the guidance of the cup wall of the material cup 2-7-3 due to their own weight and be filled into the mold sleeve 2-5-3, thereby completing the filling of the raw materials.

[0031] After the raw materials are loaded, in order to avoid interfering with the docking of the mold core 2-8-1 and the mold sleeve 2-5-3, the rodless coupling cylinder 2-7-2 will drive the material cup 2-7-3 to slide out to one side of the hydraulic cylinder again, and the telescopic end of the discharge cylinder 2-7-7 will retract to drive the sealing ball 2-7-8 to move down, so as to facilitate the sealing of the material cup 2-7-3 again.

[0032] The mold sleeve 2-5-3 and the mold rod 2-5-1 at the lower end are similar to a syringe structure. When the raw material is introduced into the mold sleeve 2-5-3, the mold rod 2-5-1 will slide down to the lowest end of the mold sleeve 2-5-3 due to its own weight and the downward pressure of the raw material. At this time, after the raw material is loaded, the explosion-proof door 4 of the raw material transfer window and the explosion-proof door 1 of the finished product transfer window are closed, and the multiple mold clamping cylinders 2-11 fixedly installed on the upper crossbeam 2-10 are controlled to shrink, and the mold clamping slide block 2-6 is pulled to slide upward along the column 2-2, and continuously approach the upper crossbeam 2-10, until the mold core 2-8-1 under the upper crossbeam 2-10 is plugged into the multiple mold sleeves 2-5-3 that move upward synchronously with the mold clamping slide block 2-6, thereby completing the assembly of the mold.

[0033] Then, the oil cylinder is controlled to push the lifting slide block 2-3 to slide upward along the pillar, and the lifting slide block 2-3 that is continuously moving upward will drive the lifting plate 2-4-7 to move upward synchronously until it contacts the lower end of the mold rod 2-5-1. After that, the lifting plate 2-4-7 continues to lift and will push the mold rod 2-5-1 to move upward in the mold sleeve 2-5-3, and compress the raw materials in the mold sleeve 2-5-3, thus starting the pressing process of the detonator. In order to avoid excessive pressure in the mold sleeve 2-5-3, which may cause damage to the equipment or instability of the detonator, a limit column 2-4-4 of a fixed length is provided on the bottom plate 2-4-1 of the top lift plate. When the upper end of the limit column 2-4-4 collides with the limit plate 2-9 on the lower end face of the upper crossbeam 2-10, the top lift plate 2-4-7 will be prevented from continuing to rise, thereby indirectly limiting the compression stroke of the mold rod 2-5-1 in the mold sleeve 2-5-3, ensuring the safety and controllability of the pressing process.

[0034] After pressing and holding the pressure for a period of time, the mold closing cylinder 2-11 and the oil cylinder will respectively drive the mold closing slide 2-6 and the lifting slide 2-3 to move downward, wherein the downward movement distance of the lifting slide 2-3 is equal to the downward movement distance of the mold closing slide 2-6 minus the height of the detonator, which means that when the mold closing slide 2-6 is completely moved down and returns to its initial state, the lifting slide 2-3 will push the mold rod 2-5-1 to continue to move a stroke of the detonator height compared to the mold sleeve 2-5-3, and then assist in ejecting the detonator after pressing and forming, so as to facilitate demolding.

[0035] At this time, the end of the mold rod 2-5-1 is just at the opening of the mold sleeve 2-5-3, so that the upper panel 2-5-6, which was originally densely covered with holes, becomes a complete plane, and the pressed detonator and the residual raw materials in the mold sleeve 2-5-3 will gather on the surface of the upper panel 2-5-6 due to the second lifting of the mold rod 2-5-1 during the demolding process. At this time, the lifting slider 2-3 does not move down temporarily, but waits until the cup fixing plate 2-7-1 drives the many cups 2-7-3 to correspond to the opening of the mold sleeve 2-5-3 one by one again before continuing to move down.

[0036] In this process, the push plate 2-7-6 installed on the end of the L-shaped bracket close to the mold assembly 2-5 will push all the residual raw materials and detonators stacked on the upper panel 2-5-6 to the receiving mechanism on the side of the mold slider 2-6 away from the material cup 2-7-3 due to the sliding of the material cup 2-7-3. The receiving mechanism will transfer the detonator to the outside through the explosion-proof door 1 of the finished product transfer window, and then close the explosion-proof door 1 of the finished product transfer window again. The above-mentioned receiving mechanism is any known device or structure that can realize the above-mentioned residual raw materials and detonators to receive and transfer, such as a robotic arm, a conveyor belt, etc. Its specific structure and feeding method will not be described in detail here.

[0037] Because a brush is provided under the sliding push plate 2-7-6, the cleaning capability of the upper panel 2-5-6 and the upper end surface of the mold rod 2-5-1 can be enhanced to avoid the problem of errors between batches of detonator pressing due to excessive residue of raw materials, which affects the pressing quality.

[0038] When the material cup 2-7-3 containing the raw materials moves to the top of the mold sleeve 2-5-3 to prepare for feeding again, the card opening and closing cylinder 2-4-5 fixedly installed on the top lifting plate base 2-4-6 is used to drive the guide rod 2-4-3 at the output end to move horizontally. The moving guide rod 2-4-3 will pull one of the two adjacent card plates 2-4-2 closer to the other card plate 2-4-2, so that the two adjacent card plates 2-4-2 are closed and contacted. The annular card hole formed on the closed card plate 2-4-2 is just embedded in the annular groove at the lower end of the mold rod 2-5-1. At this time, the oil cylinder is used to drive the top lifting slide plate to continue to move downward, and the mold rod 2-5-1 can be pulled downward synchronously until the mold rod 2-5-1 is reset. This prevents the mold rod 2-5-1 from being unable to fall back in time due to excessive friction between the mold sleeve 2-5-3 and the side wall, resulting in the mold sleeve 2-5-3 being unable to open normally, and the raw materials in the material cup 2-7-3 will overflow and accumulate on the upper panel 2-5-6 or fall into other mold sleeves 2-5-3, directly affecting the success rate of suppressing the batch of detonators.

[0039] After the mold rod 2-5-1 is reset, the card opening and closing cylinder 2-4-5 drives the guide rod 2-4-3 to translate in the opposite direction, so that the two adjacent card plates 2-4-2 are separated and the mold rod 2-5-1 is released.

[0040] Then, the discharge cylinder 2-7-7 controls the lifting of the sealing ball 2-7-8 through the swing arm 2-7-4, thereby realizing the discharge and filling of the mold sleeve 2-5-3, and this cycle is repeated to complete the continuous production process of the detonator.

[0041] In summary, the present invention, through ingenious structural design, pushes the material during the loading process, demolds during the mold separation process, and presses during the mold closing process, making the originally remote and segmented processes continuous and efficient. Compared with the traditional detonator suppression production, the production efficiency is significantly improved while ensuring the production quality.
