Description

Technical Field

[0001] The utility model relates to the technical field of explosive pressing and processing equipment, in particular to a secondary explosive pressing device with automatic core rod demoulding. Background Art

[0002] Pressing is a method for producing explosive columns, which is widely used in various countries. The pressing method is to pour granular or sheet explosives into a mold, and pressurize the loose explosives through a punch on a press to press them into a column with a certain shape, size and strength.

[0003] In the prior art, there are two ways to press and form large explosive columns: unidirectional pressing and bidirectional pressing. Unidirectional pressing easily causes uneven density of the upper and lower parts of the explosive column, affecting the quality of the explosive column. The cost of the bidirectional pressing equipment used in bidirectional pressing is relatively high, and the pressing mold is not easy to disassemble and assemble.

[0004] After the explosive powder is pressed into shape in the mold, it needs to be demolded. In the prior art, the demolding process is mostly done by directly demolding the explosive powder by the press. For a powder column with a formed core rod, only the demolding between the outer wall of the powder column and the inner cavity of the mold sleeve is completed. After the powder column is demolded, the middle formed core rod is still tightly connected to the center of the powder column, and needs to be manually pulled out. There is a certain risk of explosion and it affects efficiency.

[0005] In the prior art, for larger medicine columns, the air in the gaps between the medicine powders is not discharged during the process of pressing the medicine powders into shape, but is pressed into the medicine column, which affects the density of the medicine column. After the medicine column is placed for a period of time, the air in the medicine column expands back to its original volume, causing the medicine column to deform and increase.

[0006] Therefore, designing a secondary medicine pressing device with automatic core rod demoulding and making it easy to disassemble and assemble the medicine pressing mold, so as to ensure the quality of the finished medicine column while reducing production costs, has become a direction for further improvement.

[0047] The working principle of the utility model is as follows:

[0048] like Figure 2 As shown, the initial state of the device is: the explosive is put into the mold sleeve 11, and the light rod conveyor line 2 drives the medicine pressing mold 4 to enter the medicine pressing area of ​​the press, waiting for the first medicine pressing;

[0049] like Figure 3As shown, the first medicine pressing process of the device is as follows: the movable crossbeam 35 of the press device 1 drives the comb plate 17 to press down, and the vacuum cover 18 descends synchronously. When the vacuum cover 18 descends to the point where its lower surface fits the outer peripheral edge of the upper end of the mold sleeve 11 and covers the upper part of the upper punch 15, the vacuum generator 19 is turned on to start evacuating the inside of the mold sleeve 11. When the vacuum degree reaches the required level, the movable crossbeam 35 continues to press down, and the comb plate 17 also presses down the upper punch 15 to start the first medicine pressing. When the comb plate 17 fits the first medicine pressing stop column 24, the downward pressure is stopped, and the first medicine pressing molding is completed, and then the second medicine pressing is performed.

[0050] like Figure 4 As shown, the second medicine pressing process of the device is as follows: the movable crossbeam 35 is lifted, the lifting cylinder 30 lifts the pressing block 31, the pressing block 31 drives the supporting blocking column 32 upward so that the supporting blocking column 32 supports the lower end of the lower pressing plate 9, and the movable crossbeam 35 drives the comb plate 17 to press down for the second time. At this time, the upper punch 15 is flush with the first medicine pressing blocking column 24, and the upper punch 15 has no downward pressing tendency relative to the die sleeve 11. The lower pressing plate 9 drives the lower punch 12 to press upward relative to the die sleeve 11, squeezing the medicine column from below to achieve secondary molding, that is, the bidirectional medicine pressing effect is achieved on the unidirectional pressing device 1 through the design of the medicine pressing mold 4;

[0051] like Figure 5 As shown, the demolding process of the medicine column of the device is as follows: the movable crossbeam 35 is lifted, the lifting cylinder 30 lifts the pressure block 31, and the medicine pressing mold 4 is lifted accordingly, the support column 32 supports the lower end of the lower pressure plate 9, and the comb plate 17 moves left under the drive of the auxiliary movable module 16, and the movable crossbeam 35 drives the comb plate 17 to be pressed down, and the comb plate 17 first presses the upper end of the spring sleeve rod 21 of the elastic connecting mechanism 10, and drives the forming core rod 14 to move downward to avoid the forming core rod 14 from sticking to the center of the medicine column, which is convenient for demolding, and the movable crossbeam 35 continues to press down, and the lower pressure plate 9 drives the lower punch 12 to push the medicine column upward to complete the demolding of the medicine column.

[0052] The utility model can realize secondary medicine pressing on the one-way pressing device 1, achieving the effect of two-way medicine pressing. The whole process is completed automatically, and there is no need to manually demold the medicine column. The whole production process is safe and efficient. The one-way pressing device 1 used helps to reduce production costs, and secondary medicine pressing helps to keep the density of the upper and lower sections of the finished medicine column uniform and increase the average density. When the medicine column is demolded, the elastic connection mechanism of the core rod can be pressed first, and a downward pressing and demolding action can synchronously realize the demolding of the forming core rod and the center of the medicine column, as well as the mold sleeve meat cavity and the outer wall of the medicine column; adding a vacuuming process can avoid the generation of bubbles during the production process of the medicine column pressing, and improve the quality of the medicine column molding product; the medicine pressing device 4 adopts a replaceable design as a whole, which is convenient for the production of different medicine columns.

[0053] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
