[0043] Propellant, also known as propellant, burns regularly to release energy and produce gas to push the gunpowder of rockets and missiles. It is a type of chemical that can quickly produce a large amount of high-temperature gas when burned. It can be used to launch projectiles such as guns and cannons, rockets and missiles. It is flammable and explosive and extremely dangerous. Due to the particularity of its materials, domestic cutting equipment generally has basic transmission components such as gear racks and rotating shafts, and is equipped with semi-automatic structures such as explosion-proof servo motors or cylinders. It still requires manual feeding and cannot achieve fully automatic operation, which poses a certain risk. The finished products cut out have low precision and low efficiency, which is not conducive to mass production.

[0044] In view of this, the present invention provides a propellant sample making machine, aiming to improve the technical problems in the prior art, such as low precision of the cut finished products, inability to mass produce, low efficiency and inability to automate operations. Figures 1 to 4 This is an embodiment of the propellant prototyping machine provided by the present invention.

[0045] See also Figure 1 The propellant sample making machine 100 provided in this embodiment includes:

[0046] The workbench 101 has a loading area, a first workstation and a second workstation spaced from right to left;

[0047] The first cutting mechanism 102 comprises a first cutting tool 105, which is arranged above the workbench 101 so as to be movably moved in the up-down direction and in the left-right direction, so as to cut the propellant blank on the loading area into sheets when the first cutting tool 105 is translated downward to approach the loading area, and to cut the sheet-like propellant blank into strips when the first cutting tool 105 is translated to the left and downward to approach the first station;

[0048] The second cutting mechanism 103 includes a second cutting tool 107, which is disposed at the second station in a manner that can be translated in the up-down direction, so that when the second cutting tool 107 is translated downward to be close to the second station, the sheet-shaped propellant blank at the second station is cut into a specified shape; and

[0049] The conveying mechanism comprises a first adsorption component, which is movably arranged between the first station and the second station in the left-right direction to convey the sheet-shaped propellant blank from the first station to the second station.

[0050] In the technical solution provided in this embodiment, the upper end surface of the workbench 101 is respectively formed with a first station and a second station from right to left, and there is also a loading area on the right side of the first station. The workbench 101 is made of super-hard aluminum alloy plate, and the surface is paved with static conductive silicone rubber plate. The entire table is mainly used to complete the cutting work of the medicine blank, tablets and medicine strips and the installation support of the conveying mechanism. The holes and grooves on the plate surface are processed with high precision by laser cutting. A support frame is also provided above the workbench 101, and the support frame is used to support some devices and structures arranged above the workbench 101. For example, the first cutting tool 105 and the second cutting tool 107. The first cutting tool 105 is movably mounted on the support frame above the first station, and the second cutting tool 107 is movably mounted on the support frame above the second station. The first cutting tool 105 adopts a stainless steel (beryllium bronze) tool, the blade thickness is 2mm and the length is 150mm, and the tool has low cost and is economical.

[0051] The first cutting tool 105 has a first cutting stroke and a second cutting stroke, which respectively cut the propellant blank into different shapes. When the first cutting tool 105 performs the first cutting stroke, the first cutting tool 105 moves in the up-down direction, so that when the first cutting tool 105 moves downward to approach the loading area, the propellant blank on the loading area is cut into sheets; if the sheet-like propellant blank needs to be further cut into strips, the first cutting tool 105 then performs the second cutting stroke, which is completed at the first station. The first cutting tool 105 moves downward and to the left, and continues to cut the sheet-like propellant blank into strips.

[0052] If it is necessary to cut into a specified shape, the sheet-like propellant blank needs to be transferred to the second station. Therefore, a conveying mechanism needs to be set between the first station and the second station, which is specially used to transfer the sheet-like propellant blank cut at the first station to the second station. The second cutting tool 107 moves downward from the top of the second station to cut the sheet-like propellant blank on the second station into a specified shape. Because the sheet-like propellant blank is very fragile, it is necessary to be careful when conveying it, otherwise the cut sheet-like propellant blank will be damaged. Therefore, the conveying mechanism includes a first adsorption component, which firmly absorbs the sheet-like propellant blank by adsorption.

[0053] The propellant sample making machine 100 provided in this embodiment can cut the propellant blank into sheets, strips or specified shapes, meeting the requirements of product shape diversity. The whole process is fully automatic, the finished products cut out are high in precision, and can be mass-produced, which greatly improves production efficiency and is safe and reliable.

[0054] Further, see Figure 2 In this embodiment, the first cutting mechanism 102 also includes a first mounting seat 104, two first driving electric cylinders and a second driving electric cylinder. The first driving electric cylinder is a modular product that integrates an explosion-proof servo motor and a lead screw, converting the rotational motion of the explosion-proof servo motor into a linear telescopic motion, while converting the best advantages of the servo motor - precise speed control, precise number of revolutions control, and precise torque control - into precise speed control, precise position control, and precise thrust control; achieving high-precision linear motion. The tool positioning is accurate (±0.005mm), the cutting torque is controllable and adjustable (maximum output is 1500N), and the operating speed is adjustable from 0 to 200mm. The second driving electric cylinder is the same as above and will not be repeated here.

[0055] The support frame has a guide rail extending in the left-right direction, and the first mounting seat 104 is movably arranged in the left-right direction on the guide rail above the first station; the two first driving electric cylinders are arranged in parallel on the first mounting seat 104, and each of the first driving electric cylinders has a first power output shaft that is telescopic in the up-down direction, and one end of the first power output shaft passes through the first mounting seat 104 and is connected to the first cutting tool 105 for driving the first cutting tool 105 to move in the up-down direction. The second driving electric cylinder has a second power output shaft that is telescopic in the left-right direction, and the second power output shaft is connected to the first mounting seat 104 for driving the first mounting seat 104 to move in the left-right direction on the guide rail.

[0056] In addition, the first cutting mechanism 102 further includes a medicine baffle 106, which is disposed on the right side of the first cutting tool 105 and moves together with the first cutting tool 105, so that when loading, the medicine baffle 106 descends and abuts against the propellant blank to prevent the propellant blank from moving too much, resulting in the cut sheet of the propellant blank being too thick.

[0057] Furthermore, in this embodiment, because the weight of the propellant blank is relatively light, the process of lifting the knife during the cutting process may lift up the propellant blank, thereby damaging the propellant blank. In order to avoid this situation, the propellant sample making machine 100 also includes a medicine pressing mechanism. The medicine pressing mechanism includes a medicine pressing plate and two driving cylinders. The medicine pressing plate is arranged above the first station in an up-and-down direction so as to press the sheet-like propellant blank when the medicine pressing plate moves downward to approach the sheet-like propellant blank; the two driving cylinders are arranged in parallel on the first mounting seat 104, and each of the driving cylinders has a cylinder power output shaft that is telescopic in the up-and-down direction. One end of the cylinder power output shaft passes through the first mounting seat 104 and is connected to the medicine pressing plate for driving the medicine pressing plate to move in the up-and-down direction.

[0058] Furthermore, in this embodiment, the second cutting tool 107 includes a knife seat 108, a blade assembly, an elastic connector and a pressing plate 109, the knife seat 108 is movably disposed above the second station in the up-down direction, the blade assembly is protruding from the bottom of the knife seat 108, the pressing plate 109 is penetrated with a knife groove 110 in the up-down direction, the pressing plate 109 is elastically connected to the bottom of the knife seat 108 through the elastic connector, and the blade assembly is inserted into the knife groove 110. It is used to hide the blade assembly in the process of not cutting, which plays a protective role.

[0059] The second cutting mechanism 103 further includes a third driving electric cylinder and a second mounting seat, wherein the second mounting seat is disposed on a support frame above the workbench 101, and the third driving electric cylinder is mounted on the second mounting seat, and the third driving electric cylinder has a third power output shaft that is telescopic in the vertical direction, and one end of the third power output shaft passes through the second mounting seat and is drivingly connected to the knife seat 108 to drive the knife seat 108 to move in the vertical direction. The third driving electric cylinder is a modular product that integrates an explosion-proof servo motor and a lead screw, and converts the rotational motion of the explosion-proof servo motor into a linear telescopic motion.

[0060] It should be noted here that when the third driving electric cylinder drives the knife seat 108 to move downward and moves to abut against the sheet-like propellant blank, because the pressure plate 109 is elastically arranged under the base, if the knife seat 108 continues to press downward after abutting against the sheet-like propellant blank, the spring above the pressure plate 109 will be in a compressed state, and the pressure plate 109 will make an upward contraction movement relative to the blade assembly, and the blade assembly in the knife groove 110 initially hidden in the pressure plate 109 will extend out to cut the sheet-like propellant blank; after the cutting is completed, the knife seat 108 is lifted, and the pressure plate 109 is separated from the propellant blank, then the spring above the pressure plate 109 will return to the previous state, and then the pressure plate 109 will make a downward extension movement relative to the blade assembly, and at the same time, in this process, the pressure plate 109 can push the propellant blank off the blade assembly to prevent the propellant blank from rising with the blade assembly and preventing the propellant blank from sticking to the tool.

[0061] Specifically, see Figure 3 In this embodiment, the blade assembly includes two blades arranged at a relative interval, and the middle part of each blade protrudes in a direction close to each other to form two blade protrusions. The blade assembly is used to cut the sheet-like propellant blank into a dumbbell shape.

[0062] After the blade is installed, the exposed part has a depth of 12mm (greater than the sample thickness). The blade holder 108 is provided with a compressed air hole for easy stripping. The blade is an ultra-thin stainless steel blade produced by Hitachi Special Steel of Japan. The blade width is 30mm and the thickness is 0.1mm. The body material is quenched 30Cr13 martensitic stainless steel. The surface hardness is HRC52°±2° and the surface roughness is 0.04 microns. The length of each roll is 100 meters. The blade material is corrosion-resistant and high-strength, and the bending radius is less than R10mm. The hardness and toughness of the blade are better than 30CrMnSi and T10A. This method has a compact design structure, and the blade can be replaced in a few minutes. In addition, the blade does not have the large back angle of the old-style tool, which well guarantees the verticality and surface quality of the end face of the cut product.

[0063] Furthermore, in this example, the propellant sample making machine 100 also includes a loading mechanism, and the workbench 101 also has a loading area located on the right side of the first station. The loading mechanism includes a fourth driving electric cylinder and a push plate. The fourth driving electric cylinder is arranged below the loading area, and a slide groove penetrating the workbench 101 is formed on the workbench 101, and the slide groove extends from the loading area to the first station. The fourth driving electric cylinder has a fourth power output shaft that can be extended and retracted in the left and right directions; the push plate is arranged on the peripheral side wall of the fourth power output shaft and extends upward through the slide groove, so as to push the propellant blank to move to the first station during the movement of the fourth power output shaft from right to left. The fourth driving electric cylinder is a modular product that integrates an explosion-proof servo motor and a lead screw, and converts the rotational motion of the explosion-proof servo motor into a linear telescopic motion.

[0064] The loading mechanism is responsible for placing the propellant blanks cut from the previous process on the operating table in sequence. After the previous propellant blanks are cut into strips or slices, the subsequent propellant blanks will automatically enter the slicing process and automatically position and clamp the propellant blanks to prepare for cutting into strips or slices.

[0065] Specifically, in this embodiment, the feeding mechanism further includes two guide plates 111 extending in the left-right direction, and the two guide plates 111 are arranged in the feeding area at intervals in the front-back direction to jointly enclose a feeding channel to prevent the propellant blank from shifting during the cutting process. In order to adjust the interval between the feeding channels to adapt to propellant blanks of different shapes. The feeding mechanism further includes a plurality of adjustment structures 112, each of which includes a support and an adjustment pin. The plurality of supports are arranged at the front and rear sides of the feeding area, and one end of each adjustment pin is connected to one of the guide plates 111, and the other end is movably connected to one of the supports in the front-back direction to adjust the interval between the two guide plates 111.

[0066] Further, see Figure 4 In this example, the propellant sample making machine 100 further includes a rotary cleaning mechanism, which includes a second adsorption assembly 113 and a drive motor, the drive motor is arranged below the first station, the drive motor has a rotating shaft that rotates along the vertical axis, and the second adsorption assembly 113 is connected to the rotating shaft, so that during the rotation of the rotating shaft along the vertical axis, the propellant blanks discarded on the first station are adsorbed outside the workbench 101, so as to clean the residual propellant blanks.

[0067] Furthermore, in this example, in order to position the sheet-like propellant blank at the second station and prevent the position from shifting, the propellant sample making machine 100 also includes a positioning mechanism, which includes four positioning plates. The second station is surrounded by positioning grooves that penetrate the second station in the up-down direction. The four positioning plates are movably arranged below the second station and are arranged corresponding to the positioning grooves. The four positioning plates have a movable stroke in the up-down direction, and each two positioning plates arranged opposite to each other have a movable stroke that approaches each other. The positioning mechanism also includes four driving components, each driving component drives and connects to a positioning plate to drive the positioning plate to move. When the sheet-like propellant blank is placed in the specified position, the four positioning plates move toward each other to clamp the sheet-like propellant blank and complete the positioning.

[0068] Furthermore, in this embodiment, the propellant sample making machine 100 further includes a first storage box and a second storage box, wherein the first storage box is arranged at the front side of the first station, and the second storage box is arranged at the left side of the second station. The conveying mechanism further includes a push rod and a third adsorption assembly, wherein the push rod is arranged at the rear side of the first station in a forward-backward motion, so that during the movement of the push rod from the back to the front, the propellant blank cut into strips is pushed into the first storage box for storage; and the third adsorption assembly is arranged between the second station and the second storage box in a left-right motion, so that during the movement of the third adsorption assembly from the right to the left, the propellant blank cut into a specified shape is conveyed into the second storage box for storage.

[0069] It should be noted that the first adsorption component, the second adsorption component 113 and the third adsorption component are all suction cups, which use the difference in atmospheric pressure inside and outside to grab objects.
