Description

Technical Field

[0001] The invention belongs to the technical field of casting processing, in particular to a casting riser cutting and rapid feeding device. Background Art

[0002] A casting riser refers to a supplementary part added to the top or side of a casting to avoid defects in the casting during the casting process. Its main function is to compensate for shrinkage, that is, to supplement liquid metal during the solidification process of the casting to ensure that the casting is dense and defect-free. However, after the casting is formed, the riser will solidify into riser impurities and become a redundant part. For some plate castings, the riser impurities are generally on the upper surface of the plate casting. If these riser impurities are not cut, the dimensional accuracy and performance of the plate casting will be affected, which will cause the plate casting to be unable to be used normally in subsequent use.

[0003] A patent application with publication number CN110315055A discloses a casting riser cutting device, including a support seat, a cutting device and a magnetic seat; and the cutting device is arranged above the support seat, and the cutting device moves laterally along the support seat; a magnetic seat is arranged below the support seat, and the device fixes the entire device on the surface of the casting where the riser needs to be cut through the magnetic seat, and a cutting gun is arranged on the device, which replaces the riser cutting worker holding a large cutting torch to perform riser cutting, thereby improving the riser cutting efficiency, improving the riser cutting quality, and reducing the labor intensity of the workers.

[0004] There are still some problems in the actual application of the above scheme. When using the above device to cut the riser of the plate casting, since the production of plate castings is generally multiple, after the riser cutting of the previous plate casting is completed, it is necessary to cut the next plate casting as soon as possible. At this time, manual loading and unloading is required, and the slow speed of manual loading and unloading will seriously affect the cutting efficiency of the equipment. After the cutting, the riser impurities are easy to splash along the rotation direction of the cutting circular saw. Manual loading and unloading will greatly increase the possibility of safety accidents. If traditional stacking loading is used, the riser impurities on the surface of the plate casting will easily affect the stability of the unloading, and ultimately affect the cutting.

[0005] To this end, the present invention provides a casting riser cutting and rapid feeding device. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0032] like Figures 1 to 9As shown, a casting riser cutting and rapid feeding device according to an embodiment of the present invention comprises a base frame 1, a cutting structure 3 for cutting the riser is arranged at one end of the base frame 1, a moving device 2 is arranged at the upper end of the base frame 1, a feeding structure 4 is arranged at the upper end of the moving device 2, and the feeding structure 4 is used in conjunction with the cutting structure 3; the moving device 2 comprises a moving platform 21, and the moving platform 21 is slidably connected to the upper end of the base frame 1; the feeding structure 4 comprises: a temporary storage frame 401, and the temporary storage frame 401 is arranged on the surface of the moving platform 21, and The interior of the temporary storage frame 401 is used to place the plate casting 5; two isolation plates 402, the two isolation plates 402 are respectively slidably connected to the two side walls of the temporary storage frame 401, and the isolation plates 402 are blocked under the plate casting 5; the connecting arm 404, the two isolation plates 402 are fixedly connected by the connecting arm 404; the first limiting plate 414, the first limiting plate 414 is arranged on the upper surface of the mobile platform 21; the abutment block 410, the abutment block 410 is slidably connected to the surface of the mobile platform 21, and the abutment block 410 abuts against the plate casting 5.

[0033] Specifically, a casting riser cutting and rapid feeding device of the scheme is suitable for riser cutting of a plate casting 5. After the plate casting 5 is formed, the riser will solidify into riser impurities 51 and become redundant parts. For subsequent normal use, the riser impurities 51 of the plate casting 5 will be cut off. Since the riser impurities 51 after cutting are easy to splash along the rotation direction of the cutting circular saw 32, before cutting, the plate casting 5 needs to be fixed on the surface of the mobile platform 21 first, and the cutting circular saw 32 can be started to rotate at any time, and then the mobile platform 21 is pushed toward the direction of the cutting circular saw 32. Since the lower surface of the cutting circular saw 32 is flush with the upper surface of the plate casting 5, Therefore, when the plate casting 5 is pushed to the lower surface of the cutting circular saw 32, only the riser impurities 51 located on the upper surface of the plate casting 5 are in contact with the cutting circular saw 32, and finally the riser impurities 51 are separated from the plate casting 5. At this time, the cut plate casting 5 needs to be removed. Since the production of plate castings 5 ​​is generally multiple, after the riser impurities 51 of the previous plate casting 5 are cut, the next plate casting 5 needs to be cut as soon as possible. At this time, manual loading and unloading is required, and the slow speed of manual loading and unloading will seriously affect the cutting efficiency of the equipment. For this purpose, a temporary storage frame 401 is designed. Before cutting, multiple plate castings 5 ​​to be cut are placed in the temporary storage frame 401. The bottom sheet casting 5 is located inside the frame 401, and the bottom sheet casting 5 is located on the surface of the isolation plate 402. The connecting arm 404 is then started, and the connecting arm 404 drives the isolation plate 402 to move back and forth horizontally. When the isolation plate 402 moves for the first time, the bottom sheet casting 5 will fall downwards because there is no limit on the isolation plate 402. When the isolation plate 402 moves again to reset, the bottom sheet casting 5 will fall downwards again, and the upper sheet casting 5 will be limited by the isolation plate 402 above, so that the upper sheet casting 5 will not fall. At this time, the reciprocating movement of the isolation plate 402 can realize the sheet The casting 5 is quickly unloaded, and then the abutment block 410 is started. The abutment block 410 will move toward the direction of the plate casting 5, and finally the plate casting 5 that falls alone will be abutted along the surface of the first limiting plate 414 to the position to be cut. At this time, the mobile platform 21 can be pushed to cut. During cutting, since there is a first limiting plate 414 at the rear of the plate casting 5, no additional fixation is required. At this time, the cutting of the riser impurities 51 of the plate casting 5 is completed, and after the cutting is completed, the mobile platform 21 will be reset and move next time. At this time, the connecting arm 404 will continue to unload the plate casting 5 to realize cyclic unloading.

[0034] like Figures 1 to 3As shown, the mobile device 2 also includes: a connecting block 24, which is arranged at the lower end of the mobile platform 21; a screw 23, which is threadedly connected to the connecting block 24; a driving motor 25, which is arranged at one end of the screw 23; a roller 22, which is rotatably connected to both ends of the connecting block 24, and the roller 22 is rotatably connected to the surface of the base frame 1; the feeding structure 4 also includes a slide rail 411, which is arranged on the surface of the mobile platform 21, and the abutment block 410 is slidably connected to the surface of the slide rail 411; the cutting structure 3 used in conjunction with the feeding structure 4 also includes a cutting frame 31, which is arranged at the upper end of the base frame 1.

[0035] Specifically, when the plate casting 5 falls at the position to be cut, the drive motor 25 is started, and the drive motor 25 will drive the screw 23 to rotate. Since the connecting block 24 is threadedly connected to the screw 23, and the rollers 22 at both ends of the connecting block 24 slide on the surface of the base frame 1, the connecting block 24 will move toward the cutting circular saw 32 at this time, and finally cut the riser impurities 51.

[0036] like Figures 1 to 5 As shown, the lower end of the isolation plate 402 is slidably connected to the auxiliary plate 403 , the side wall of the temporary storage frame 401 is rotatably connected to the first gear 405 , and both the isolation plate 402 and the auxiliary plate 403 are meshed with the first gear 405 .

[0037] Specifically, by setting the auxiliary plate 403, when the isolation plate 402 moves in the direction away from the plate casting 5, the isolation plate 402 will drive the first gear 405 below to rotate, and the first gear 405 will drive the auxiliary plate 403 to move in the direction close to the plate casting 5. Finally, when the plate casting 5 falls for the first time, both ends of the plate casting 5 are supported, making the fall more stable.

[0038] like Figure 5 As shown, one end of the isolation plate 402 close to the plate casting 5 is an inclined surface, and the inclined surface of the isolation plate 402 contacts the bottom surface of the plate casting 5.

[0039] Specifically, by setting one end of the isolation plate 402 as a slope, when the isolation plate 402 moves toward the plate casting 5, the slope of the isolation plate 402 will first contact the plate casting 5, so that the plate casting 5 can be more accurately located on the surface of the isolation plate 402.

[0040] like Figures 1 to 6As shown, a sliding rod 407 is provided at the upper end of the mobile platform 21, and a reciprocating screw rod 408 is rotatably connected to the lower part of the sliding rod 407. A connecting plate 406 is connected to one end of the connecting arm 404, and the connecting plate 406 is slidably connected to the surface of the sliding rod 407. The connecting plate 406 is threadedly connected to the reciprocating screw rod 408. A connecting track 409 is sleeved on the surface of the roller 22, and the other end of the connecting track 409 is sleeved on the surface of the reciprocating screw rod 408.

[0041] Specifically, by setting the connecting track 409, when it is necessary to unload the plate casting 5, it is only necessary to start the driving motor 25 to move the mobile platform 21, and the roller 22 will also rotate at this time, and during the rotation, the connecting track 409 located on the surface of the roller 22 will drive the reciprocating screw 408 to rotate together. Since the connecting plate 406 is slidably connected to the surface of the sliding rod 407, and the connecting plate 406 is also threadedly connected to the reciprocating screw 408, when the reciprocating screw 408 rotates, the connecting plate 406 will reciprocate along the surface of the reciprocating screw 408, and finally the connecting plate 406 will drive the connecting arm 404 to reciprocate together to achieve unloading.

[0042] like Figures 1 to 8 As shown, a rack 413 is provided at one end of the abutment block 410 , a second gear 412 is provided on the surface of the reciprocating screw rod 408 , and the second gear 412 is meshed with the rack 413 .

[0043] Specifically, while the reciprocating screw 408 rotates, the second gear 412 located on the surface of the reciprocating screw 408 will mesh with the second gear 412 and drive the abutment block 410 to move, and finally automatically push the unloaded plate casting 5 to the position to be cut. Embodiment 2

[0044] like Fig. 9 As shown, in contrast to Example 1, another implementation of the present invention is that one end of the upper surface of the mobile platform 21 close to the first limiting plate 414 is rotatably connected to a conveying roller 416, and the conveying roller 416 is in contact with the plate casting 5.

[0045] Specifically, by setting a conveying roller 416, when the abutment block 410 pushes the plate casting 5 out, the plate casting 5 will contact the conveying roller 416. At this time, the conveying roller 416 is started to rotate, and the conveying roller 416 will drive the plate casting 5 to move, so that the plate casting 5 can fall more accurately at the position to be cut.

[0046] like Fig. 9 As shown, a conveying frame 415 is provided at one end of the upper surface of the movable platform 21 close to the first limiting plate 414 , a sliding block 417 is provided inside the conveying frame 415 , and the sliding block 417 is connected to a conveying roller 416 .

[0047] Specifically, when the plate casting 5 moves to contact the conveying roller 416, the sliding block 417 is started, and the sliding block 417 will drive the conveying roller 416 to rotate, so that the plate casting 5 can fall more accurately at the position to be cut.

[0048] like Fig. 9 As shown, the sliding block 417 is slidably connected to the inside of the conveying frame 415, and the upper and lower ends of the sliding block 417 are provided with adjustment springs 418.

[0049] Specifically, since there are riser impurities 51 on the surface of the plate casting 5 before cutting, when the conveying roller 416 drives the plate casting 5 to move, the riser impurities 51 are likely to affect the transportation of the conveying roller 416. For this purpose, an adjustment spring 418 is provided, and the sliding block 417 is set to slide inside the conveying frame 415, and adjustment springs 418 are provided at the upper and lower ends of the sliding block 417, so that the conveying roller 416 can be adaptively adjusted when it contacts the riser impurities 51.

[0050] like Fig. 9 As shown, a second limiting plate 419 is provided at one end of the side wall of the mobile platform 21 close to the conveying frame 415 , and a plurality of auxiliary rollers 420 are rotatably connected to the inner wall of the second limiting plate 419 , and the plurality of auxiliary rollers 420 are in contact with the side wall of the plate casting 5 .

[0051] Specifically, by setting the second limiting plate 419, after the plate casting 5 moves to the position to be cut, the side wall of the plate casting 5 will contact the auxiliary roller 420, so that the plate casting 5 can move smoothly, and when cutting, the second limiting plate 419 will also limit and fix the plate casting 5, so that the plate casting 5 will not be offset during cutting.

[0052] Working principle: Before cutting the riser impurities 51 of the plate casting 5, first place a plurality of plate castings 5 ​​to be cut inside the temporary storage frame 401. At this time, the plate casting 5 at the bottom will be located on the surface of the isolation plate 402. Then, the drive motor 25 is started, and the drive motor 25 will drive the screw 23 to rotate. Since the connecting block 24 is threadedly connected to the screw 23, and the rollers 22 at both ends of the connecting block 24 slide on the surface of the base frame 1, the connecting block 24 will move toward the cutting circular saw 3. 2, and at this time, the connecting track 409 on the surface of the roller 22 will drive the reciprocating screw 408 to rotate together. Since the connecting plate 406 is slidably connected to the surface of the sliding rod 407, and the connecting plate 406 is also threadedly connected to the reciprocating screw 408, when the reciprocating screw 408 rotates, the connecting plate 406 will reciprocate along the surface of the reciprocating screw 408, and finally the connecting plate 406 will drive the connecting arm 404 to reciprocate, and the connecting arm 404 will drive the isolation plate 402 When the isolation plate 402 moves together, when the isolation plate 402 moves for the first time, since there is no limit of the isolation plate 402, the lowest layer of the plate casting 5 will fall downward. When the isolation plate 402 moves again for resetting, the lowest layer of the plate casting 5 will fall downward again, and the upper layer of the plate casting 5 will be limited by the upper isolation plate 402, so that the upper layer of the plate casting 5 will not fall. At this time, the abutment block 410 is started, and the abutment block 410 will move toward the direction of the plate casting 5, and finally the plate casting 5 that falls alone will be abutted along the surface of the first limit plate 414 to the position to be cut. At this time, the moving platform 21 can be pushed to cut. During cutting, since there is a limit of the first limit plate 414 at the rear of the plate casting 5, no additional fixation is required. At this time, the cutting of the riser impurities 51 of the plate casting 5 is completed, and after the cutting is completed, the moving platform 21 will be reset and move for the next time. At this time, the connecting arm 404 will continue to unload the plate casting 5 to achieve cyclic unloading.
