Description

Technical Field

[0001] This utility model relates to the field of gunpowder production, specifically a gunpowder material wire cutting device. Background Technology

[0002] The cutting of explosives is involved in various fields, including military industry, fireworks and firecrackers, mining engineering, and chemical engineering. This involves cutting explosive charges into appropriately sized products. However, in many cases, the cutting of explosives is still done manually. This manual method is not only inefficient but also relies heavily on the experience of the operators, leading to inconsistent cutting quality and posing significant safety hazards.

[0003] With technological advancements, some automated cutting equipment for explosives has emerged in existing technologies. For example, patent CN211541339U discloses a pneumatic clamping and cutting device. This device has three cylinders fixed on its support frame, each connected to a clamping block and a cutting blade. Two clamping blocks are located on either side of the cutting blade, and a guide seat is located directly below the cutting blade and the two clamping blocks. When the device is in operation, the explosive to be cut is placed on the guide seat. The two clamping blocks move to clamp the upper surface of the material to be cut, and then the cutting blade moves to complete the cutting operation. However, after each cut, an operator needs to remove the cut product, manually reset the mechanical limiting mechanism, and push the next section of product in for further cutting. Its automation level needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a wire cutting device for explosives, which is applicable to the cutting of explosives with a wider range of diameters and can achieve automatic continuous feeding, cutting and unloading of explosives, thereby improving the automation level of the equipment.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A wire cutting device for explosive materials includes a frame and a feeding and positioning mechanism, a wire cutting mechanism, and a unloading mechanism disposed within the frame. The feeding and positioning mechanism is provided with a clamping block assembly having X-axis and Y-axis degrees of freedom of movement, and the clamping block assembly includes two opening and closing positioning clamping blocks. The wire cutting mechanism is disposed above the feeding and positioning mechanism and is provided with a lifting plate. The lifting plate is provided with a driving wheel, a driven wheel, and a cutting wire, and the cutting wire passes around the driving wheel and the driven wheel in a closed loop. The unloading mechanism is disposed below the feeding and positioning mechanism and is provided with a movable unloading box.

[0007] The feeding and positioning mechanism includes an X-axis moving module, an X-axis moving base, a Y-axis moving module, and a Y-axis moving base. The X-axis moving module is mounted on the frame, and the X-axis moving base is driven to move by the X-axis moving module. The Y-axis moving module and the Y-axis moving base are both mounted on the X-axis moving base, and the Y-axis moving base is driven to move by the Y-axis moving module. The clamping block assembly is mounted on the Y-axis moving base.

[0008] The clamping block assembly includes a clamping block screw and a screw drive element. The clamping block screw has two threaded sections with opposite directions of rotation. The lower ends of the two positioning clamping blocks of the clamping block assembly slide with the Y-axis moving seat. Each of the two positioning clamping blocks has a movable nut that is respectively fitted onto different threaded sections of the clamping block screw. The clamping block screw is driven to rotate by the screw drive element. Both sides of the Y-axis moving seat are provided with tension and opening detection elements. The positioning clamping blocks detect the movement distance through the tension and opening detection elements on the corresponding sides.

[0009] The Y-axis movable seat is provided with a clamping shaft mounting seat, and a clamping shaft is threadedly installed on the clamping shaft mounting seat. The front end of the clamping shaft clamps the gunpowder material, and the rear end is provided with a clamping adjustment element.

[0010] The feeding and positioning mechanism includes a small part pre-clamping fixture, which includes two material clamping blocks that are fastened together. The gunpowder material is first clamped by the two material clamping blocks, and then the small part pre-clamping fixture is clamped by the two positioning clamping blocks.

[0011] The wire cutting mechanism includes a mounting base, a drive wheel drive device, and a lifting device. The mounting base is fixed on the frame, the rear side of the lifting plate is slidably connected to the mounting base, the lifting device is located on the mounting base, and the lifting plate is driven to rise and fall by the lifting device. The drive wheel drive device is located on the rear side of the lifting plate, and the drive wheel is driven to rotate by the drive wheel drive device.

[0012] The drive wheel has a drive wheel shaft rotatably mounted on the lifting plate and connected to the drive wheel drive device at the rear side; the lifting plate has a tension adjustment seat, and the driven wheel has a driven wheel shaft rotatably mounted on the corresponding tension adjustment seat at the rear side.

[0013] The lower part of the lifting plate is equipped with a temperature sensor to monitor the cutting temperature of the lower section of the cutting wire, and the upper part of the lifting plate is equipped with a cooling pipe for blowing air to cool the upper section of the cutting wire.

[0014] The lower end of the lifting plate is provided with a rotatable feeding rod. When cutting the gunpowder material, the feeding rod faces upward, and the cut gunpowder material product is pressed down by rotating the feeding rod. The rear side of the lifting plate is provided with a rotary drive device, and the feeding rod is driven to rotate by the rotary drive device.

[0015] The feeding mechanism includes a feeding box drive device and a moving plate, wherein the feeding box is provided with a connecting plate fixedly connected to the moving plate, and the moving plate is provided with a moving block fixedly connected to the feeding box drive device; the feeding box is provided with a moving guide plate, the frame is provided with a moving guide rail, and the moving guide plate slides in cooperation with the moving guide rail on the corresponding side.

[0016] The advantages and positive effects of this utility model are as follows:

[0017] 1. This utility model uses two positioning clamping blocks that open and close in the clamping block assembly to fix the gunpowder material to be cut. When the diameter of the gunpowder material is small, a small pre-clamping fixture can be used to assist in clamping and fixing the gunpowder material. At the same time, the cutting wire in the wire cutting mechanism has a relatively long cutting length. Therefore, this utility model can be applied to the cutting of gunpowder materials with more diameters, and has a wider range of applications, while ensuring the cutting quality.

[0018] 2. After the gunpowder material is cut once, the lifting plate in the wire cutting mechanism rises, and then the Y-axis moving module in the feeding and positioning mechanism drives the clamping block assembly and the gunpowder material to move down to the wire cutting mechanism again, thereby realizing automatic continuous feeding and cutting of the gunpowder material, which improves the automation level of the equipment.

[0019] 3. After each cut is completed, the feeding rod at the bottom of the lifting plate in the wire cutting mechanism will rotate downwards to press down the cut gunpowder material product and separate it from the cutting wire, so that it falls into the feeding box of the feeding mechanism, thereby realizing the automatic feeding of the gunpowder material product, which further improves the automation level of this utility model.

[0020] 4. During the cutting process of this utility model, the temperature sensor at the bottom of the lifting plate in the wire cutting mechanism monitors the cutting temperature of the lower side of the cutting wire in real time, while the cooling pipe at the top of the lifting plate blows cooling air onto the upper side of the cutting wire to achieve timely cooling of the cutting wire, thereby ensuring the safety of the cutting process.

[0021] 5. After all the gunpowder material has been cut, the feeding box in the feeding mechanism can be automatically moved to the outside of the frame to discharge the material. Therefore, except for placing the gunpowder material to be cut into the clamping block assembly, the rest of the process can be completed automatically, thereby realizing the separation of man and machine during continuous gunpowder material cutting operations and eliminating personal safety hazards.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] like Figures 1-5 As shown, this utility model includes a frame 1 and a feeding and positioning mechanism 2, a wire cutting mechanism 3, and a unloading mechanism 4 disposed in the frame 1, wherein... Figure 2 As shown, the feeding and positioning mechanism 2 is equipped with a clamping block assembly with X-axis and Y-axis movement freedom. In this embodiment, the X-axis is the length direction of the frame 1, and the Y-axis is the width direction of the frame 1. Figure 3 As shown, the clamping block assembly includes two opening and closing movable positioning clamping blocks 203; as Figure 1 As shown, the wire cutting mechanism 3 is positioned above the feeding and positioning mechanism 2, and as... Figure 4 As shown, the wire cutting mechanism 3 is equipped with a lifting plate 304, on which a driving wheel 305, a driven wheel 306, and a cutting wire 307 are mounted, and the cutting wire 307 is arranged in a closed loop around the driving wheel 305 and the driven wheel 306; Figure 1 As shown, the unloading mechanism 4 is located below the loading and positioning mechanism 2, and the unloading mechanism 4 is equipped with a movable unloading box 403. In this embodiment, the cutting wire 307 can be diamond wire, which is a well-known technology in the art.

[0031] In operation, the explosive material to be cut is clamped and fixed by two positioning clamps 203 in the clamping block assembly. Then, the clamping block assembly moves along the X direction until the explosive material is aligned with the lower side of the wire cutting mechanism 3. Then, the clamping block assembly moves along the Y direction to below the cutting line 307 of the wire cutting mechanism 3, and the lifting plate 304 of the wire cutting mechanism 3 descends to complete the cutting operation of the explosive material using the cutting line 307. The cutting line 307 has a relatively long cutting length and a relatively flat cutting surface, which can ensure the cutting quality. The cut explosive material product falls into the feeding box 403.

[0032] like Figure 2 As shown, in this embodiment, the feeding and positioning mechanism 2 includes an X-axis moving module 201, an X-axis moving seat 2011, a Y-axis moving module 202, and a Y-axis moving seat 2021. The X-axis moving module 201 is mounted on the frame 1, and the X-axis moving seat 2011 is driven to move by the X-axis moving module 201. Both the Y-axis moving module 202 and the Y-axis moving seat 2021 are mounted on the X-axis moving seat 2011, and the Y-axis moving seat 2021 is driven to move by the Y-axis moving module 202. The clamping block assembly is mounted on the Y-axis moving seat 2021. The X-axis moving module 201 and the Y-axis moving module 202 can adopt suitable structures as needed, such as a motor-driven screw-nut structure, where the screw is driven to rotate by a motor, and the lower side of the moving seat is fixedly connected to the nut mounted on the screw. Alternatively, a rodless cylinder or similar device can be used.

[0033] like Figure 2 As shown in this embodiment, the frame 1 is provided with an X-axis guide rail 2012, and the X-axis moving seat 2011 is provided with an X-axis slider on its lower side to cooperate with the X-axis guide rail 2012.

[0034] like Figure 2 As shown in this embodiment, the X-axis movable seat 2011 is provided with a Y-axis guide rail 2022, and the Y-axis movable seat 2021 is provided with a Y-axis slider on its lower side to cooperate with the Y-axis guide rail 2022.

[0035] like Figure 3As shown, in this embodiment, the clamping block assembly includes a clamping block screw 204 and a screw drive element 205. The clamping block screw 204 has two threaded segments with opposite directions of rotation. The lower ends of the two positioning clamping blocks 203 of the clamping block assembly are slidably connected to the Y-axis moving seat 2021. Each of the two positioning clamping blocks 203 has a movable nut inside, which is respectively fitted onto different threaded segments of the clamping block screw 204. The clamping block screw 204 is driven to rotate by the screw drive element 205, thereby driving the positioning clamping blocks 203 on different threaded segments to achieve opening and closing movement.

[0036] like Figure 3 As shown in this embodiment, the Y-axis moving seat 2021 is provided with a clamping block slide rail 210, and the lower end of the positioning clamping block 203 is provided with a clamping block slider 211 that cooperates with the clamping block slide rail 210.

[0037] like Figure 3 As shown, in this embodiment, the Y-axis movable seat 2021 is provided with a screw mounting seat 206, and the two ends of the clamping block screw 204 are respectively mounted on the screw mounting seat 206 on the corresponding side.

[0038] like Figure 3 As shown, in this embodiment, the clamping screw 204 is manually driven, that is, the screw drive element 205 adopts a handwheel structure, and turning the handwheel drives the clamping screw 204 to rotate. This invention can also use an automatic drive method to drive the clamping screw 204 to rotate as needed. For example, the screw drive element 205 can be a geared servo motor to drive the clamping screw 204 to rotate.

[0039] like Figure 3 As shown, in this embodiment, the Y-axis movable seat 2021 is provided with a clamping shaft mounting seat 209, and a clamping shaft 208 is threadedly installed on the clamping shaft mounting seat 209. Tightening the clamping shaft 208 can help clamp and position the gunpowder material to be cut. The rear end of the clamping shaft 208 is provided with a clamping adjustment element 2081. In this embodiment, the clamping shaft 208 is manually adjusted, that is, the clamping adjustment element 2081 is a rotating handle. Tightening the rotating handle drives the clamping shaft 208 to extend and retract.

[0040] like Figure 3 As shown, during normal cutting, the propellant to be cut is clamped and fixed by two positioning clamps 203. As the propellant length shortens with each cut, the Y-axis moving seat 2021 moves the propellant towards the lower side of the wire cutting mechanism 3, thereby achieving automatic feeding of the propellant. When the diameter of the propellant is relatively small, the feeding and positioning mechanism 2 can use a small pre-clamping fixture 207 for positioning, such as... Figure 3aAs shown, the small part pre-clamping fixture 207 includes two material clamping blocks 2071 that can be snapped together. The gunpowder is first clamped and fixed by the two material clamping blocks 2071. At this time, the gunpowder and the small part pre-clamping fixture 207 become one. Then, the two positioning clamping blocks 203 close and clamp the small part pre-clamping fixture 207 without directly clamping the smaller gunpowder, thereby realizing the clamping and positioning of the smaller gunpowder.

[0041] like Figure 3 As shown in this embodiment, both sides of the Y-axis moving seat 2021 are provided with opening and closing detection elements 212. The positioning clamping block 203 detects the moving distance through the opening and closing detection elements 212 on the corresponding side, thereby realizing the clamping movement positioning control of the two positioning clamping blocks 203. The opening and closing detection element 212 is a commercially available product, such as a through-beam sensor.

[0042] like Figure 4 As shown, in this embodiment, the wire cutting mechanism 3 includes a mounting base 301, a drive wheel 302, and a lifting device 303. The mounting base 301 is fixed to the frame 1. The rear side of the lifting plate 304 is slidably connected to the mounting base 301. The lifting device 303 is mounted on the mounting base 301, and the lifting plate 304 is driven to rise and fall by the lifting device 303. The drive wheel 302 is located on the rear side of the lifting plate 304, and the drive wheel 305 is driven to rotate by the drive wheel 302. In this embodiment, the mounting base 301 is provided with a lifting slide rail, and the rear side of the lifting plate 304 is provided with a lifting slider that cooperates with the lifting slide rail. The lifting device 303 can be a rodless cylinder, and the drive wheel 302 can be a geared servo motor.

[0043] like Figure 4 As shown, in this embodiment, the driving wheel 305 has a driving wheel shaft rotatably mounted on the lifting plate 304 and connected to the driving wheel drive device 302. Additionally, the lifting plate 304 has a tension adjustment seat 3061, and the driven wheel 306 has a driven wheel shaft rotatably mounted on the corresponding tension adjustment seat 3061. The driving and driven wheel shafts must first have sufficient length to meet the cutting requirements of different lengths of the propellant tip. The cutting length of the propellant tip is within the distance range from the cutting line 307 to the lifting plate 304. Secondly, the tension adjustment seat 3061 can be adjusted in position on the lifting plate 304 as needed to ensure the cutting line 307 is tensioned. In this embodiment, the lifting plate 304 has multiple sets of adjusting screw holes, and the bolts fixing the tension adjustment seat 3061 can be installed in the corresponding set of adjusting screw holes as needed.

[0044] like Figure 4As shown, in this embodiment, the lifting plate 304 has a temperature sensor 308 at its lower part and a cooling pipe 310 at its upper part. The lower side of the cutting wire 307 is used for wire cutting of the explosive material. The temperature sensor 308 is used to monitor the temperature of the lower section of the cutting wire 307 in real time during cutting. The cooling pipe 310 blows cooling air onto the upper section of the cutting wire 307 throughout the cutting process to reduce the temperature of the cutting wire 307 and achieve timely cooling. If the temperature sensor 308 detects that the temperature has reached the warning temperature, the equipment control system will automatically stop the equipment for cooling. When the temperature sensor 308 detects that the temperature has returned to the normal range, the equipment will restart cutting. The temperature sensor 308 is a commercially available product.

[0045] like Figure 4 As shown, in this embodiment, the lower end of the lifting plate 304 is provided with a rotatable feeding rod 309. During cutting, the feeding rod 309 faces upward. After cutting, the feeding rod 309 rotates downward to press down the cut explosive material product to ensure that the material is completely separated from the cutting wire 307. In this embodiment, a rotary drive device (such as a servo motor) is provided on the rear side of the lifting plate 304, and the feeding rod 309 is driven to rotate by the rotary drive device.

[0046] like Figure 5 As shown, in this embodiment, the feeding mechanism 4 includes a movable feeding box 403. During cutting, the feeding box 403 moves to below the wire cutting mechanism 3. After the material product is cut, it is pressed down by the feeding rod 309 and separated from the cutting wire 307 before falling into the feeding box 403. After the feeding box 403 is full, it moves to the outside of the frame 1.

[0047] like Figure 5 As shown, in this embodiment, the feeding mechanism 4 includes a feeding box driving device 401 and a moving plate 402. A connecting plate 4031 is fixedly connected to the moving plate 402 on the feeding box 403. A moving block 4021 is fixedly connected to the feeding box driving device 401 on the moving plate 402. The feeding box driving device 401 drives the feeding box 403 to move via the connecting plate 402. Additionally, a moving guide plate 4032 is provided on the feeding box 403, and a moving guide rail 404 is provided inside the frame 1. The moving guide plate 4032 slides in conjunction with the moving guide rail 404 on the corresponding side, thereby guiding the movement of the feeding box 403. The feeding box driving device 401 can be equipped with a suitable device, such as a cylinder, as needed.

[0048] The working principle of this utility model is as follows:

[0049] The present invention includes the following steps in operation:

[0050] Step 1: Place the gunpowder material into the clamping block assembly of the feeding and positioning mechanism 2, such as... Figure 3 As shown, the two positioning clamping blocks 203 in the clamping block assembly are initially in an open state. After the gunpowder material is placed in, the two positioning clamping blocks 203 are driven to close and move to clamp the gunpowder material by the clamping block screw 204. The front part of the gunpowder material needs to be exposed with sufficient length to meet the needs of subsequent continuous feeding and cutting.

[0051] Additionally, in this step, if the diameter of the gunpowder material is relatively small, such as Figures 3-4 As shown, at this time, the two material clamping blocks 2071 of the small pre-clamping fixture 207 can be used to clamp and fix the gunpowder material first, and then the small pre-clamping fixture 207 can be clamped and fixed by the two positioning clamping blocks 203.

[0052] Step 2: After the explosive material is placed, the X-direction moving module 201 in the loading and positioning mechanism 2 drives the clamping block assembly to move a set distance along the X direction so that the explosive material moves to the position below the alignment wire cutting mechanism 3.

[0053] Step 3: The Y-axis moving module 202 in the feeding and positioning mechanism 2 drives the clamping block assembly to move a set distance along the Y-axis so that the front end of the explosive material moves to below the wire cutting mechanism 3.

[0054] Step Four: As Figure 4 As shown, the drive wheel 305 in the wire cutting mechanism 3 starts to rotate, which in turn drives the cutting wire 307 to rotate. Then, the lifting plate 304 in the wire cutting mechanism 3 descends so that the cutting wire 307 completes the cutting operation on the gunpowder material. The cut gunpowder material product is pressed down by the feeding rod 309 on the lifting plate 304 and separated from the cutting wire 307, and falls into the feeding box 403 of the feeding mechanism 4.

[0055] Step 5: After the gunpowder material is cut once, the lifting plate 304 in the wire cutting mechanism 3 rises to a set height. Then, the Y-axis moving module 202 in the feeding and positioning mechanism 2 drives the clamping block assembly to move a set distance along the Y-axis, so that the front end of the gunpowder material moves to below the wire cutting mechanism 3 again. Then, the lifting plate 304 descends again to allow the cutting wire 307 to complete the second cutting operation. The cut gunpowder material product also falls into the unloading box 403 of the unloading mechanism 4.

[0056] Step 6: Repeat step 5 until all the gunpowder material is cut, and then the feeding box 403 in the feeding mechanism 4 moves to the outside of the frame 1 to pick up the product.

[0057] Other examples Figure 4As shown, in the present invention, when cutting gunpowder materials, the temperature sensor 308 at the lower part of the lifting plate 304 monitors the cutting temperature of the lower section of the cutting wire 307 in real time, and the cooling pipe 310 at the upper part of the lifting plate 304 blows cooling air to the upper section of the cutting wire 307 to achieve timely cooling of the cutting wire 307, thereby ensuring the safety of the cutting process.
