Description

Technical Field

[0001] This utility model relates to the field of fireworks production equipment technology, specifically a hydraulic forming device for pyrotechnic powder. Background Technology

[0002] In order for fireworks to achieve the spraying function of their internal firework shells, a fixed amount of explosive charge needs to be filled into the paper tube as the power source for propulsion. To achieve mass production of fireworks products, automated pressing equipment is required for the filling operation.

[0003] In existing fireworks powder molding devices, the gunpowder powder is manually filled into each filling hole during the molding process. Excess gunpowder powder is then removed using a scraper. Simultaneously, the upper and lower hydraulic presses are activated to apply pressure to the gunpowder powder in the filling holes, causing it to solidify into a powder column. After the pressure plate is released, the top plate is used to push the powder column out of the filling hole. Finally, the material is manually discharged. During filling, it is necessary to manually remove excess gunpowder powder using a scraper, which poses a significant safety hazard. Furthermore, the collection of the powder column during discharge is also quite cumbersome.

[0004] Based on this, a hydraulic forming apparatus for pyrotechnic powder is now provided, which can eliminate the drawbacks of existing apparatuses. Summary of the Invention

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, a hydraulic forming device for pyrotechnic powder includes a base 100, an upper pressing block 300, a lower pressing block 400, a template 500, a cleaning component 600, and a powder collection component 700. The lower pressing block 400 is mounted on the base 100, the template 500 is positioned above the lower pressing block 400, and the upper pressing block 300 is positioned above the template 500. The cleaning component 600 is also mounted on the upper end of the template 500. The powder collection component 700 is positioned between the template 500 and the lower pressing block 400. In use, the lower pressing block 400 is first moved to a position adjacent to the template 500. The lower surface is attached, and then gunpowder is poured into the upper end of the template 500. Next, the cleaning component 600 is used to scrape off the excess gunpowder. Then, the upper pressure block 300 is moved downwards and together with the lower pressure block 400, presses the template 500 together, so that the gunpowder in the template 500 is compressed into a powder column. Then, the lower pressure block 400 is moved downwards, and then the powder column collecting component 700 is moved to the lower end of the template 500. Then, the upper pressure block 300 continues to move downwards, pushing out the powder column in the template 500, so that the powder column falls into the powder column collecting component 700.

[0027] In one embodiment, such as Figure 1As shown, the lower end of the base 100 is provided with support legs 101, and a crossbar 102 is provided between the support legs 101.

The support legs 101 and the support rod 103 are provided in four places, respectively located at the four corners of the base 100.

[0028] In one embodiment, such as Figure 2 As shown, a lower hydraulic cylinder 201 is provided at the lower end of the base 100, and the output end of the lower hydraulic cylinder 201 is connected to the lower pressure block 400. An upper hydraulic cylinder 202 is provided at the upper end of the top plate 104, and the output end of the upper hydraulic cylinder 202 is connected to the upper pressure block 300. In use, the lower pressure block 400 is driven to move upward by the lower hydraulic cylinder 201, and the upper pressure block 300 is driven to move downward by the upper hydraulic cylinder 202.

[0029] In one embodiment, such as Figure 3 As shown, the upper pressure block 300 includes a mounting block 301, which is slidably mounted on the support rod 103. The mounting block 301 is connected to the output end of the upper hydraulic cylinder 202. The mounting block 301 has threaded holes 302 evenly distributed on it. A connecting post 304 is threadedly connected to the threaded hole 302. One end of the connecting post 304 is provided with a pressure post 303. In use, the upper hydraulic cylinder 202 drives the mounting block 301 to move up and down along the support rod 103, thereby driving the pressure post 303 to move.

[0030] In one embodiment, such as Figure 2 As shown, the lower pressure block 400 includes a fixed base 401, which is fixed to the upper end of the base 100. The fixed base 401 is provided with a sliding groove 402, and a movable block 403 is slidably arranged in the fixed base 401. The lower end of the movable block 403 is connected to the output end of the lower oil cylinder 201. A slider 404 is provided on the movable block 403, and the slider 404 is slidably arranged in the sliding groove 402. In use, the movable block 403 is driven to move up and down along the sliding groove 402 by the lower oil cylinder 201.

[0031] In one embodiment, such as Figure 4 As shown, the template 500 includes a mounting base 501, which is fixed to the support rod 103. A template block 502 is bolted inside the mounting base 501. The template block 502 has evenly distributed mold holes 503, and the inner diameter of the mold holes 503 matches the pressure column 303. In use, gunpowder is added into the mold hole 503, and then the gunpowder column is formed by the up and down compression of the pressure column 303 and the movable block 403.

[0032] In one embodiment, such as Figure 4As shown, the cleaning component 600 includes two stops 601 symmetrically arranged on both sides of the mounting base 501. One end of the stop 601 is provided with a scraper 602, and a fixing plate 604 is provided on one side of the scraper 602. The fixing plate 604 is bolted to the mounting base 501. A telescopic rod 603 is provided on the fixing plate 604. The output end of the telescopic rod 603 is connected to the scraper 602. The other end of the stop 601 is provided with a slag collection box 605, which is bolted to the mounting base 501. In use, by controlling the extension of the telescopic rod 603, the scraper 602 is moved along the surface of the template block 502, thereby pushing the excess gunpowder on the surface of the template block 502 into the slag collection box 605.

[0033] In one embodiment, such as Figure 5 As shown, the pill collection assembly 700 includes a slide rail 701, which is fixed inside the support rod 103.

One end of the pill collection plate 704 is provided with a handle 706. In use, after the pill is formed, the handle 706 is used to push the pill collection plate 704 directly below the template block 502. Then, the pressure column 303 pushes the pill out of the mold hole 503 and makes it fall into the collection groove 705.

[0034] The above embodiment discloses a hydraulic forming device for pyrotechnic powder. In use, the lower pressing block 400 is first moved to fit against the lower surface of the template 500. Then, gunpowder is poured into the upper end of the template 500. Next, by controlling the extension of the telescopic rod 603, the scraper 602 is moved along the surface of the template block 502, thereby pushing the excess gunpowder on the surface of the template block 502 into the slag collection box 605. Then, the upper pressing block 300 is moved downward, so that the pressure column 303 is inserted into the die hole 503. Together with the lower pressing block 400, the gunpowder in the die hole 503 is squeezed and compacted into a gunpowder column. Then, the lower pressing block 400 is moved downward, and the gunpowder column collecting assembly 700 is moved to the lower end of the template 500. Then, the upper pressing block 300 continues to move downward, and the pressure column 303 pushes out the gunpowder column in the die hole 503, so that the gunpowder column falls into the gunpowder column collecting assembly 700.
