Description

Technical Field

[0001] The present invention belongs to the technical field of cutting equipment, and specifically relates to a reciprocating cutting equipment for processing stainless steel castings. Background Art

[0002] The casting industry is the foundation of the manufacturing industry and plays a key role in the national economic development and industrial manufacturing development. The riser is a structure in the production of stainless steel castings to ensure good forming of the formed part and enable the material to flow smoothly and evenly into the mold. After casting and forming, it needs to be cut for subsequent processing operations.

[0003] A patent application with the publication number of CN119035645A discloses a cutting device for the riser of stainless steel castings, including a clamping module, a cutting module and a collection module. A clamping space is arranged inside the clamping module, and the clamping module is used to fix a plurality of stainless steel casting risers arranged at intervals in the clamping space along the horizontal length direction. A cutting module is arranged on one side of the clamping module. This device solves the problems in the prior art that cutting the riser of stainless steel castings manually on the workbench has not only high intensity, low cutting efficiency, but also long time-consuming for cleaning the waste generated by cutting.

[0004] The above solution still has some problems in actual application. When using the above cutting device to cut the riser of stainless steel castings, first, the stainless steel casting needs to be fixed at the part to be cut, and then a circular saw is used for cutting. Since the cutting work of stainless steel castings is continuous and a large number of stainless steel castings need to be cut each time, after cutting one stainless steel casting, if the circular saw needs to be retracted to the original position again, it will greatly affect the working cycle. And this continuous work will cause the circular saw to wear due to factors such as friction and high temperature. The cutting edge of the circular saw will quickly become dull, and even chipping or crater wear will occur. If it cannot be replaced in time, it will greatly affect the cutting effect and rate.

[0005] Therefore, the present invention provides a reciprocating cutting equipment for processing stainless steel castings. Summary of the Invention

When performing cutting work, by setting a switching frame, first place a new cutting tool on the surface of the placement bar, and then place the casting on the conveying rollers for conveying. When it is conveyed to the lower end of the operation plate, start the rotation of the cutting tool located at one end of the transverse movement plate. Since the cutting tool can move up and down on the surface of the transverse movement plate, and the transverse movement plate can move horizontally on the surface of the operation plate, when the cutting tool performs cutting work, it can perform reciprocating cutting on the casting, thereby realizing continuous cutting. After cutting for a period of time, start the transverse movement plate to move towards the fixed toothed plate. During the movement, the fixed gear located on the surface of the cutting tool will contact the fixed toothed plate and drive the cutting tool to rotate. Since the threaded ring at one end of the cutting tool is threadedly connected to the first screw rod, the cutting tool will then disengage from the lifting plate. Subsequently, start the driving shaft, and the driving shaft will drive the switching frame to rotate, thereby replacing the cutting tool that has been cutting for a period of time with a brand-new cutting tool on the surface of the placement bar for subsequent cutting work. This device uses a reciprocating cutting method for cutting. The cutting tool moves back and forth during the cutting process, without the need to frequently retract or reposition, and can achieve continuous cutting, which is suitable for large-scale processing. Moreover, the switching frame can also automatically replace the cutting tool that has been cutting for a period of time, thereby avoiding the phenomenon that continuous cutting work causes damage to the cutting tool and ultimately affects the cutting effect.

Specific Embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] Embodiment 1: As Figures 1 to 13As shown in the figure, a reciprocating cutting device for stainless steel casting processing according to an embodiment of the present invention includes a base frame 1. A conveying structure 2 is provided inside the base frame 1. The conveying structure 2 includes conveying rollers 21. A cutting structure 3 is provided at the upper end of the base frame 1. A switching structure 4 is provided at one end of the cutting structure 3. The cutting structure 3 includes: an operation board 302, which is arranged at the upper end of the base frame 1; a transverse movement board 307, which is slidably connected inside the operation board 302 and reciprocates inside the operation board 302; a lifting board 308, which is slidably connected to one end of the transverse movement board 307; a cutting knife 301, which is arranged at one end of the lifting board 308; a rotating shaft 305, which is arranged on the surface of the cutting knife 301; two clamping frames 303, which are slidably connected to the surface of the conveying rollers 21. The switching structure 4 includes: a placement strip 403, which is rotatably connected to one side of the base frame 1; a driving shaft 407, which is rotatably connected to one end of the operation board 302 close to the placement strip 403; a switching frame 405, which is arranged at one end of the driving shaft 407 and can slide at one end of the driving shaft 407; placement grooves 414, which are opened at both ends of the switching frame 405; two auxiliary clamping pieces 406, which are respectively rotatably arranged on one side of both ends of the switching frame 405 close to the placement grooves 414.

[0023] Specifically, a reciprocating cutting device for stainless steel casting processing in this solution is mainly used for cutting the riser of the casting 5. This is because during the casting process, the riser is a channel for introducing molten metal and discharging gases. After casting, the riser will form redundant metal parts that need to be removed by cutting. During operation, first place the casting 5 on the surface of the conveying roller 21, and then place a new cutting tool 301 on the surface of the placing bar 403. At this time, start the conveying roller 21 to rotate. The conveying roller 21 will convey the casting 5 to the lower end of the cutting tool 301 at one end of the lifting plate 308. At this time, start the clamping frame 303. The two clamping frames 303 will move closer to each other and then clamp and fix the casting 5. Subsequently, start the cutting tool 301, the lifting plate 308 and the transverse moving plate 307 above the casting 5. The lifting plate 308 will slide on the surface of the transverse moving plate 307 to control the cutting depth. The transverse moving plate 307 will slide inside the operation plate 302, so that the cutting tool 301 makes a transverse cut on the casting 5. When the cutting tool 301 contacts the riser of the casting 5, the riser can be cut off. Moreover, the cutting tool 301 moves back and forth during the cutting process, without the need to frequently retreat or reposition, and continuous cutting can be achieved, which is suitable for large-scale processing. After cutting for a period of time, start the transverse moving plate 307 to move towards the placing bar 403 again. When the cutting tool 301 at one end of the lifting plate 308 moves to one side of the switching frame 405, start the driving shaft 407. The driving shaft 407 will drive the switching frame 405 to rotate, so that the placing grooves 414 at both ends of the switching frame 405 are moved into contact with the cutting tool 301. At this time, start the auxiliary clamping piece 406. The auxiliary clamping piece 406 will rotate to clamp the rotating shaft 305 on the surface of the cutting tool 301. And at this time, move the switching frame 405 a certain distance away from the lifting plate 308, so that the cutting tool 301 is separated from the lifting plate 308. Then start the driving shaft 407 to rotate again, so that the new cutting tool 301 is moved to one end of the lifting plate 308. Subsequently, move the switching frame 405 a certain distance closer to the lifting plate 308 to realize the replacement of the new cutting tool 301. By setting the switching structure 4, the replacement of the cutting tool 301 can be realized during the reciprocating movement of the cutting tool 301, thus avoiding the phenomenon that continuous cutting work damages the cutting tool 301 and ultimately affects the cutting effect.

[0024] Such as Figures 1 to 10As shown in the figure, a slide rail 11 is provided at the upper end of the base frame 1, and the operation board 302 slides on the surface of the slide rail 11. The cutting structure 3 further includes: a first screw rod 309 provided at one end of the lifting plate 308; a threaded ring 306 provided at one end of the rotating shaft 305, and the first screw rod 309 is threadedly connected to the threaded ring 306; a fixed gear 304 provided at one end of the cutting knife 301 away from the threaded ring 306. The switching structure 4 further includes: a fixed plate 401 provided on one side of the base frame 1; a fixed shaft 402 provided on the surface of the fixed plate 401, and the placing strip 403 rotates on the surface of the fixed shaft 402; a fixed toothed plate 415 provided at one end of the operation board 302, and the fixed gear 304 meshes with the fixed toothed plate 415; a fixed rod 413 provided at both ends of the switching frame 405, and the auxiliary clip 406 rotates on the surface of the fixed rod 413.

[0025] Specifically, during the cutting process, the cutting knife 301 and the lifting plate 308 are threadedly connected by the threaded ring 306 and the first screw rod 309. After cutting for a period of time, the transverse moving plate 307 is restarted to move towards the placing strip 403. During the moving process, the fixed gear 304 located on the surface of the cutting knife 301 will mesh with the fixed toothed plate 415 and drive the cutting knife 301 to rotate, so that the threaded ring 306 is disengaged from the first screw rod 309. Subsequently, when the placing grooves 414 at both ends of the switching frame 405 move to contact the cutting knife 301, starting the fixed rod 413 can make the auxiliary clip 406 rotate, thereby switching the cutting knife 301.

[0026] As Figures 1 to 9 shown in the figure, a sliding rod 408 is provided inside the switching frame 405, and one end of the sliding rod 408 is connected to the driving shaft 407. A connecting arm 409 is provided at the other end of the sliding rod 408. A third screw rod 411 is rotatably connected to one end of the switching frame 405 near the auxiliary clip 406. A connecting track 412 is sleeved on the surface of the third screw rod 411, and the other end of the connecting track 412 is sleeved on the surface of the fixed rod 413. A threaded sleeve 410 is provided at one end of the connecting arm 409, and the threaded sleeve 410 is threadedly connected to the third screw rod 411.

[0027] Specifically, when the placement grooves 414 at both ends of the switching frame 405 move to contact the cutting tool 301, the switching frame 405 is toggled a certain distance in the direction away from the lifting plate 308. During the movement, since the sliding rod 408 is connected to the driving shaft 407, the sliding rod 408 and the connecting arm 409 will not move at this time. However, due to the movement of the switching frame 405, the third screw 411 located inside the switching frame 405 will also be driven to rotate by the threaded sleeve 410 during the movement, and finally drive the fixed rod 413 to rotate through the connecting track 412, realizing the automatic clamping of the auxiliary clamping piece 406.

[0028] As Figures 1 to 3 shown, a return spring 404 is sleeved on the surface of the fixed shaft 402, and one end of the return spring 404 is connected to the placement strip 403, and the other end of the return spring 404 is connected to the fixed plate 401.

[0029] Specifically, by arranging the return spring 404 on the surface of the fixed shaft 402, when the new cutting tool 301 is placed on the surface of the placement strip 403, the return spring 404 will enable the cutting tool 301 to be placed stably. When switching the cutting tool 301, the return spring 404 will not affect the rotation of the cutting tool 301 and the switching frame 405, and after the rotation is completed, it can also drive the placement strip 403 to automatically reset.

[0030] Embodiment 2: As Figures 6 to 13 shown, compared with Embodiment 1, another implementation manner of the present invention is as follows: An output gear 310 is rotatably connected to the lower end of the base frame 1 near the conveying roller 21, and two connecting toothed plates 311 are slidably connected to one end of the base frame 1 near the output gear 310, and the connecting toothed plates 311 are engaged with the output gear 310. The connecting toothed plates 311 are connected to the clamping frame 303. A plurality of rotating rods 314 are provided on one side of the clamping frame 303, a first clamping block 313 is rotatably connected to the surface of the rotating rod 314, and a plurality of second clamping blocks 316 are rotatably connected to the surface of the first clamping block 313.

[0031] Specifically, by arranging a plurality of rotatable first clamping blocks 313 on the surface of the clamping frame 303, and a plurality of second clamping blocks 316 are further arranged on the surface of the first clamping block 313. When clamping and fixing the casting 5, the output gear 310 is started to rotate, and the output gear 310 will drive the two clamping frames 303 to move towards the casting 5 through the connecting toothed plates 311. When the first clamping block 313 and the second clamping block 316 contact the surface of some castings 5 with different curvatures, they can be automatically adjusted, greatly increasing the contact area, so as to adapt to castings 5 of different shapes and sizes, ensuring the stability of the casting 5 during the clamping process and reducing vibration.

[0032] AsFigures 11 to 12 As shown, a first coil spring 315 is sleeved on the surface of the rotating rod 314, and a second clamping block 316 is connected to the first clamping block 313 through a second coil spring 317.

[0033] Specifically, by providing the first coil spring 315 and the second coil spring 317, after the casting 5 is cut and no clamping is required, the first coil spring 315 and the second coil spring 317 can drive the first clamping block 313 and the second clamping block 316 to reset, so as to facilitate subsequent clamping operations.

[0034] As Figure 12 shown, a plurality of anti-slip pads 318 are provided on the surface of the second clamping block 316.

[0035] Specifically, since the second clamping block 316 is in direct contact with the casting 5, by providing a plurality of anti-slip pads 318 on the surface of the second clamping block 316, the friction between the second clamping block 316 and the casting 5 can be increased, thereby making the fixing effect better.

[0036] As Figures 1 to 6 shown, a plurality of auxiliary rollers 22 are provided at one end of the operation plate 302 away from the clamping frame 303, and the auxiliary rollers 22 are provided between the conveying rollers 21.

[0037] Specifically, since the riser of the casting 5 will fall through the gap between the conveying rollers 21 for recycling after cutting, but some castings 5 may also fall through the gap between the conveying rollers 21 due to their small volume after cutting. By providing the auxiliary rollers 22, the gap between the conveying rollers 21 can be reduced, and after the casting 5 is cut, it will be conveyed with the assistance of the auxiliary rollers 22 to avoid the occurrence of falling.

[0038] As Figures 11 to 13 shown, a water storage frame 319 is provided at the lower end of the conveying roller 21. A plurality of water spraying nozzles 320 are opened at the upper end of the water storage frame 319. A sealing pad 322 is slidably connected inside the water storage frame 319, and the sealing pad 322 is in contact with the inner wall of the water storage frame 319.

[0039] Specifically, by providing the water storage frame 319, before cutting, the inside of the water storage frame 319 is filled with water, and then the sealing pad 322 is started. The sealing pad 322 will move upward, so that the water inside will be sprayed out from the water spraying nozzles 320 onto the surface of the casting 5, thereby reducing the temperature of the casting 5 and reducing the thermal influence during cutting.

[0040] As Figures 11 to 13As shown, a second screw 312 is provided at the upper end of the output gear 310, and one end of the second screw 312 extends into the interior of the water storage frame 319. A meshing plate 321 is provided inside the gasket 322, and the meshing plate 321 meshes with the second screw 312. The meshing plate 321 is slidably connected up and down inside the water storage frame 319.

[0041] Specifically, when clamping the casting 5, the output gear 310 will also drive the meshing plate 321 to move up and down through the second screw 312. Since the meshing plate 321 is connected to the gasket 322, the gasket 322 will move upward at this time, thereby realizing the water spraying on the casting 5.

[0042] Working principle: During operation, first place the casting 5 on the surface of the conveying roller 21, and then place a new cutting tool 301 on the surface of the placing strip 403. At this time, start the rotation of the conveying roller 21, and the conveying roller 21 will convey the casting 5 to the lower end of the cutting tool 301 at one end of the lifting plate 308. At this time, start the rotation of the output gear 310, and the output gear 310 will drive the two clamping frames 303 to move towards the casting 5 through the connecting toothed plate 311, and then clamp and fix the casting 5. Subsequently, start the cutting tool 301, the lifting plate 308 and the transverse moving plate 307 at the upper end of the casting 5. The lifting plate 308 will slide on the surface of the transverse moving plate 307 to control the cutting depth. The transverse moving plate 307 will slide inside the operation plate 302, so that the cutting tool 301 performs a transverse cut on the casting 5. When the cutting tool 301 contacts the riser of the casting 5, the riser can be cut off, and the cutting tool 301 moves back and forth during the cutting process, without the need to frequently retract or reposition, and continuous cutting can be achieved, which is suitable for mass production. After cutting for a period of time, start the transverse moving plate 307 to move towards the placing strip 403 again. During the movement, the fixed gear 304 on the surface of the cutting tool 301 will engage with the fixed toothed plate 415 and drive the cutting tool 301 to rotate, so that the threaded ring 306 is disengaged from the first screw rod 309. When the cutting tool 301 at one end of the lifting plate 308 moves to one side of the switching frame 405, start the driving shaft 407, and the driving shaft 407 will drive the switching frame 405 to rotate, so that the placing grooves 414 at both ends of the switching frame 405 are moved into contact with the cutting tool 301. At this time, move the switching frame 405 a certain distance away from the lifting plate 308. During the movement, since the sliding rod 408 is connected to the driving shaft 407, the sliding rod 408 and the connecting arm 409 will not move at this time. However, due to the movement of the switching frame 405, the third screw rod 411 inside the switching frame 405 will also be driven to rotate by the threaded sleeve 410 during the movement, and finally drive the fixed rod 413 to rotate through the connecting track 412, so as to clamp the rotating shaft 305 on the surface of the cutting tool 301. And at this time, move the switching frame 405 a certain distance away from the lifting plate 308, so that the cutting tool 301 is disengaged from the lifting plate 308, and start the driving shaft 407 to rotate again, so as to move the new cutting tool 301 to one end of the lifting plate 308, and then move the switching frame 405 a certain distance towards the lifting plate 308 to realize the replacement of the new cutting tool 301.
