Description

Technical Field

[0001] The utility model relates to the field of detonator production devices, in particular to a device for collecting detonator shell group molds. Background Art

[0002] In weapon systems, detonators are the main explosive materials for blasting engineering. Their function is to generate ignition energy to detonate various explosives, detonating cords, and booster tubes. Detonators include a shell and a tube. The shell 4 has a structure such as Figure 1 As shown, the shell is generally cylindrical, with one axial end open as a shell opening 4.1 of the shell 4 and the other axial end closed. A firing hole 4.2 is defined in the center of the closed axial end of the shell 4. The diameter of the shell opening 4.1 is much larger than the diameter of the firing hole 4.2. The interior of the shell is filled with gunpowder. After the detonator shells are produced, they need to be collected. Existing methods often involve manual collection, requiring the shells to be neatly arranged and organized, resulting in low efficiency. Utility Model Content

[0003] The utility model provides a device for collecting detonator shell group molds, so as to solve the problem of low efficiency in manual shell collection in the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is:

[0005] The device for collecting detonator shell group molds is characterized in that it includes a grate plate, a shell collection plate, and a rubbing plate; the grate plate is horizontal, the shell collection plate is horizontally fixed above the grate plate, the top surface of the shell collection plate has a plurality of parallel distributed grooves, and the shell collection plate is provided with a plurality of through holes corresponding to each groove position, each through hole vertically penetrates the shell collection plate, each through hole includes a cylindrical section and an orifice section located at the upper end of the cylindrical section, wherein the horizontal cross-section of the orifice section is elliptical, and the orifice section is The vertical cross-section is an arc shape, and the orifice section of each through hole is located at the bottom of the corresponding groove, and the through holes corresponding to the same groove are distributed in a straight line along the extension direction of the corresponding groove; a vertical punch is connected to each through hole position on the grate plate, and the upper end of each punch passes through the cylindrical section of the corresponding through hole and extends into the orifice section, and the outer diameter of the upper end of the punch matches the aperture of the firing through hole of the tube shell; the rubbing board is arranged above the tube shell collecting plate, and the rubbing board can slide and rise and fall horizontally above the tube shell collecting plate.

[0006] Furthermore, the tube shell collecting plate is surrounded by baffles on three sides to form a fence, and the tops of the baffles all exceed the top surface of the tube shell collecting plate. The rubbing board is placed above the tube shell collecting plate, and the rubbing board can slide horizontally through the gap of the fence.

[0007] Furthermore, the top surface of the tube shell collecting plate is provided with a plurality of parallel distributed ridges, the vertical cross section of each ridge is arc-shaped, and the grooves are formed by the spaces between adjacent ridges.

[0008] Furthermore, the grate plate is also penetrated by a plurality of vertical screws, and a threaded hole is provided at the bottom of the tube shell collecting plate corresponding to each screw position, and the upper end of each screw is screwed into the threaded hole at the bottom of the tube shell collecting plate.

[0009] When the utility model is in operation, multiple tube shells are dropped onto the top of the tube shell collecting plate. Then, a washboard is placed above the tube shell collecting plate and pressed against the tube shells. The washboard is then slid back and forth horizontally to rub each tube shell into the groove of the tube shell collecting plate. When all tube shells have fallen into different grooves, the washboard is lowered, and the washboard is then slid back and forth again to rub the tube shells in the groove into the through hole.

[0010] Continue to rub the washboard to flip the tube shell until the tube shell partially enters the orifice section of the through hole. Since the horizontal cross-section of the orifice section at the top of the through hole is elliptical and the vertical cross-section of the orifice section is arc-shaped, the portion of the tube shell that enters the orifice section of the through hole can flip within the orifice section, and the shell opening diameter of the tube shell is much larger than the outer diameter of the upper end of the punch. Therefore, even if the shell opening of the tube shell enters the orifice section and is sleeved outside the upper end of the punch, the tube shell can still continue to flip. Only when the tube shell is flipped to the axial closed end to enter the orifice section, and the firing through hole of the axial closed end of the tube shell is sleeved outside the upper end of the punch, the punch limiter can fix the tube shell and prevent it from moving, that is, the posture of the tube shell is fixed. Therefore, by rubbing the washboard, all tube shells can be limited one by one in the orifice section of each through hole with their axial closed ends facing downward. Finally, the tube and shell collection plate is removed from above the grate plate, leaving tubes and shells with their axial closed ends penetrating downward into the through-hole opening section in each groove of the tube and shell collection plate. In this way, the tube and shell group molds can be collected at one time, and each tube and shell are neatly arranged (i.e., all tube and shells have their axial closed ends facing downward and their shell openings facing upward).

[0011] Compared with the prior art, the utility model can collect the tube shell group mold manually, and can also realize automatic collection of the tube shell group mold by driving the rubbing board action through a motor or the like, and has the advantages of high tube shell collection efficiency and neat arrangement of the tube shells.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-9 As shown, this embodiment discloses a device for collecting detonator shell molds, comprising a grate plate 1, a shell collection plate 2, and a scrubbing plate 3. The grate plate 1 is horizontal and comprises a base plate 1.1 and a punch seat 1.2. The base plate 1.1 is placed horizontally on a work surface such as the ground or a workbench top. The punch seat 1.2 is pressed on the top of the base plate 1.1. A plurality of vertical screws 1.3 are installed through the base plate 1.1, and each screw 1.3 extends upward through the punch seat 1.2.

[0023] The tube and shell collecting plate 2 is horizontally arranged above the punch seat 1.2 in the grate plate 1. The bottom of the tube and shell collecting plate 2 is provided with a threaded hole corresponding to the position of each screw 1.3. The upper end of each screw 1.3 is screwed into the threaded hole at the bottom of the tube and shell collecting plate 2, thereby making the tube and shell collecting plate 2 detachable and fixed above the grate plate 1 through each screw 1.3.

[0024] The top of the tube and shell collection plate 2 features multiple parallel ridges 2.1. Each ridge 2.1 is parallel to the long side of the plate 2 and is the same length as the long side of the tube and shell 2.1. Each ridge 2.1 has an arc-shaped vertical cross-section, and the spaces between adjacent ridges 2.1 form grooves 2.2. The vertical depth of each groove 2.2 is less than the diameter and axial length of the tube and shell, allowing a portion of the tube to be exposed when it is dropped into the groove 2.2. The horizontal width of each groove 2.2 is greater than or equal to the diameter of a tube and less than 1.2 times the diameter of a tube and shell. As a result, when multiple tubes are dropped into the groove 2.2, they can only be arranged in a straight line along the extension direction of the groove 2.2. The arc-shaped ridges 2.1 facilitate the rotation of the tubes within the groove 2.2.

[0025] The tube and shell collection plate 2 is provided with a plurality of vertical through-holes corresponding to each channel 2.2. Each through-hole extends vertically through the tube and shell collection plate 2. Each through-hole comprises a cylindrical section 2.3 and an orifice section 2.4 located at the upper end of the cylindrical section 2.3. The horizontal cross-section of the orifice section 2.4 is elliptical, and the vertical cross-section of the orifice section 2.4 is arc-shaped. Each through-hole's orifice section 2.4 is located at the inner bottom of the corresponding channel 2.2. The minor axis of the elliptical horizontal cross-section of the orifice section 2.4 is greater than or equal to the outer diameter of one tube and less than 1.2 times the outer diameter of one tube. The through-holes corresponding to the same channel 2.2 are distributed linearly along the extension direction of the corresponding channel 2.2 (i.e., the long side of the tube and shell collection plate 2).

[0026] A vertical punch 1.4 is fixedly connected to each through-hole position corresponding to the tube shell collecting plate 2 on the punch seat 1.2 in the grate plate 1. The upper end of each punch 1.4 passes through the cylindrical section 2.3 of the corresponding through-hole and extends into the orifice section 2.4, and the outer diameter of the upper end of the punch 1.4 matches the aperture of the firing through-hole of the tube shell.

[0027] The washboard 3 is located above the tube and shell collecting plate 2 and can slide horizontally and rise and fall freely above the tube and shell collecting plate. During operation, when a tube and shell fall on the top surface of the tube and shell collecting plate 2, the washboard 3 is placed above the tube and shell collecting plate 2 to press all the tube and shell. The washboard 3 is then slid horizontally to rub the washboard 3, and all the tube and shell are rubbed into different grooves 2.2. The tube and shells in each groove 2.2 are arranged in a straight line along the extension direction of the groove 2.2. At this time, the washboard 3 is lowered and pressed against the portion of each tube and shell exposed from the groove 2.2. The washboard 3 is then continued to slide horizontally to rub the washboard 3. The washboard 3 acts on the portion of the tube and shell exposed from the groove 2.2, causing the tube and shell to flip over in the groove 2.2.

[0028] When the tube shell is flipped over to partially enter the orifice section 2.4 of the through hole, if the tube shell wall or shell opening falls into the orifice section 2.4, the upper end of the punch 1.4 in the orifice section 2.4 will hit the tube shell wall, so the tube shell position cannot be fixed when the tube shell wall enters the orifice section 2.4. Moreover, the diameter of the tube shell shell opening is much larger than the diameter of the upper end of the punch 1.4, so the tube shell position cannot be fixed when the shell opening enters the orifice section 2.4. At this time, the rubbing plate 3 continues to be rubbed. Since the horizontal cross-section of the orifice section 2.4 is elliptical and the vertical cross-section of the orifice section 2.4 is circular, the tube shell can continue to flip over in the orifice section 2.4. Only when the tube shell is flipped over to the axial closed end and enters the orifice section 2.4, and the firing through-hole of the axial closed end of the tube shell is sleeved outside the upper end of the punch 1.4, the tube shell cannot be further rubbed due to the limiting effect of the upper end of 1.4, and the tube shell is now fixed in the axial closed end downward position. Thus, by rubbing the rubbing plate multiple times, all the tube shells in each groove 2.2 can be made to enter the orifice section 2.4 one by one with their axial closed ends facing downward, and the firing through-hole of each tube shell can be sleeved outside the upper end of the punch 1.4 in the corresponding orifice section 2.4, thereby achieving the fixation of all the tube shells with their axial closed ends facing downward and their shell openings facing upward.

[0029] In this embodiment, the tube and shell collecting plate 2 is surrounded on three sides by retaining bars 2.5, forming a fence. The tops of the retaining bars 2.5 extend upwards beyond the top surface of the tube and shell collecting plate 2. A washboard 3 is positioned above the tube and shell collecting plate 2, with the three sides of the washboard 3 closely adjoining the portions of the retaining bars 2.5 extending upwards beyond the top surface of the tube and shell collecting plate 2. The fence limits the washboard 3 from rubbing the tubes and shells, allowing them to move only at the top of the tube and shell collecting plate 2. Furthermore, the washboard 3 can be freely raised and lowered within the fence, sliding horizontally through the gaps in the fence.
