[0015] The present invention has the following beneficial effects:

[0016] (1) The present invention provides a shearing device for processing metal parts. When the cutter descends to cut the metal plate, the metal plate contacts the grinding plate 1 for a while and presses the grinding plate 1 downward. The grinding plate 1 drives the fixed block to descend. The fixed block drives the T-shaped telescopic connecting block to descend. The T-shaped telescopic connecting block drives the transmission plate to descend. The transmission plate drives the Z-shaped plate to descend. The Z-shaped plate squeezes the gas in the L-shaped air cavity. The gas enters the air box through the gas transmission hole and then drives the piston plate to move in the direction of the transmission plate. The piston plate drives the push plate to move. The push plate drives the moving block to move. The moving block drives the connecting plate to move. The connecting plate drives the hinged plate to move in the direction of the transmission plate. The hinged plate drives the T-shaped telescopic connecting block to slide and descend in the direction of the transmission plate. The T-shaped telescopic connecting block drives the fixed block and the grinding plate 1 to move in the direction of the transmission plate. The two grinding plates 1 grind the inclined surface of the cutter in the process of approaching each other, so as to prevent the inclined surface of the cutter from becoming blunt due to long-term use and affecting the shearing quality.

[0017] (2) The present invention provides a shearing device for processing metal parts. During shearing, a driving motor is started, the driving motor drives the rotating shaft to rotate, the rotating shaft drives the half gear to rotate, the half gear drives the rectangular moving block to descend under the action of two tooth plates, and the rectangular moving block drives the cutter to descend. After the cutter shears the metal plate, the plane of the cutter contacts the movable plate, and the movable plate is pushed into the grinding chamber under the action of the inclined surface of the movable plate. At this time, the springs 1 on the plurality of telescopic rods generate an outward thrust. In the process of the cutter continuing to move downward, it contacts the spring 1 and the grinding plate 2 on the back of the movable plate. The grinding plate 2 continues to grind the plane of the cutter under the thrust of the telescopic rod, thereby avoiding the generation of burrs and unevenness on the cut surface of the metal plate after shearing, improving the shearing quality, making the grinding of the cutter more comprehensive, and ensuring that the cutter is normally sharp when shearing the metal plate.

[0018] (3) The present invention provides a shearing device for processing metal parts. In the process of the fixed block approaching the transmission plate, the fixed block simultaneously drives the L-shaped push rod to move, the L-shaped push rod drives the L-shaped movable plate to move, the L-shaped movable plate drives the telescopic slide rod to move, the telescopic slide rod will push the corresponding curved teeth to move, the curved teeth drive the disc to rotate, the disc drives the telescopic rod to rotate, the telescopic rod drives the push rubber block to rotate, after the push rubber block contacts the sheared metal plate, it will shrink under the action of spring four, and at the same time, the spring four will also give the push rubber block a force to push outward, so that the push rubber block will be closer to the sheared metal plate and at the same time increase the friction between the push rubber block and the sheared metal block, with the simultaneous rotation of the two push rubber blocks corresponding to the left and right sides of the bearing platform, the sheared metal plate will be pushed to move backward, and the sheared metal plate will be pushed into the storage tank, so as to avoid the sheared metal plate blocking and affecting the shearing work of the metal plate behind, thereby reducing labor and effectively improving the shearing work efficiency.

[0032] See also Figure 1-Figure 8As shown, the present invention is a shearing device for metal parts processing, comprising a carrier 1, a support leg 2 is fixedly installed at the bottom of the carrier 1, a grinding mechanism 01 is arranged on the carrier 1, and the grinding mechanism 01 includes a grinding box 3 fixedly installed on the carrier 1, and also includes:

[0033] An L-shaped air cavity 4 is provided in the polishing box 3, a Z-shaped plate 5 is slidably installed in the L-shaped air cavity 4, two air boxes 6 are fixedly installed on the top of the Z-shaped plate 5, air supply holes 7 are respectively provided on the bottom inner walls of the two air boxes 6, the two air supply holes 7 respectively penetrate the two air boxes 6, piston plates 8 are respectively fixedly installed in the two air boxes 6, the two piston plates 8 are respectively slidably connected to the two air boxes 6, pushing plates 9 are respectively fixedly installed on the sides of the two piston plates 8 close to each other, the ends of the two push plates 9 close to each other extend to the outside of the air box 6 respectively, moving blocks 10 are respectively fixedly installed on the sides of the two push plates 9 close to each other, connecting plates 11 are respectively fixedly installed on the tops of the two moving blocks 10, hinged plates 12 are respectively fixedly installed on the tops of the two connecting plates 11, fixed blocks 13 are respectively hingedly installed on the tops of the two hinged plates 12, and polishing plates 14 are respectively fixedly installed on the two fixed blocks 13.

[0034] like Figure 3 and Figure 6 As shown, the grinding mechanism 01 also includes a T-shaped telescopic connecting block 15 fixedly installed on the back of the two fixed blocks 13, the bottom end of the T-shaped telescopic connecting block 15 extends into the air box 6, a transmission plate 16 is fixedly installed on the bottom end of the T-shaped telescopic connecting block 15, and return springs 17 are fixedly installed on the left and right sides of the transmission plate 16, respectively, and the ends of the two return springs 17 that are away from each other are fixedly connected to the two moving blocks 10 respectively.

[0035] The hinged plate 12 drives the T-shaped telescopic connecting block 15 to slide and descend in the direction of the transmission plate 16, and the T-shaped telescopic connecting block 15 drives the fixed block 13 and the grinding plate 14 to move in the direction of the transmission plate 16. When the cutter 30 rises, the return spring 17 will push the two moving blocks 10 away from each other under the action of elastic force. At the same time, 10 pushes the two piston plates 8 away from each other to send the gas in the air box 6 to the L-shaped air cavity 4 and make the Z-shaped plate 5 rise. The Z-shaped plate 5 will drive the grinding plate 14 to rise, and prepare for the next grinding.

[0036] like Figure 5 As shown, the grinding mechanism 01 also includes a grinding chamber 18 opened in the grinding box 3, a plurality of telescopic rods 19 are fixedly installed on the front inner wall of the grinding chamber 18, a movable plate 20 is fixedly installed at the ends of the plurality of telescopic rods 19, a spring 21 is respectively wound around the plurality of telescopic rods 19, the front ends of the plurality of springs 21 are fixedly connected to the grinding chamber 18, the ends of the plurality of springs 21 are fixedly connected to the movable plate 20, and a grinding plate 22 is fixedly installed on the back of the movable plate 20.

[0037] After the cutter 30 has sheared the metal plate, the plane of the cutter 30 will contact the movable plate 20, and the movable plate 20 will be pushed into the grinding chamber 18 by the inclined surface of the movable plate 20. At this time, the springs 1 21 on the telescopic rods 19 will generate an outward thrust. When the cutter 30 continues to move downward, it will contact the spring 1 grinding plate 22 on the back of the movable plate 20. The grinding plate 22 will continue to grind the plane of the cutter 30 under the thrust of the telescopic rod 19, so as to avoid the phenomenon of burrs and unevenness on the cut surface of the metal plate after shearing. The quality of shearing is improved, the grinding of the cutter 30 is more comprehensive, and the cutter 30 is ensured to be sharp in normal state when shearing the metal plate.

[0038] like Figure 2 As shown, a shearing mechanism 02 is provided on the top of the supporting platform 1, and the shearing mechanism 02 includes a fixed frame 23 fixedly installed on the top of the supporting platform 1, two L-shaped limit blocks 24 are fixedly installed on the back of the fixed frame 23, and rectangular moving blocks 25 are slidably installed in the two L-shaped limit blocks 24, and tooth plates 26 are fixedly installed on the left inner wall and the right inner wall of the rectangular moving block 25 respectively, and a rotating shaft 27 is rotatably installed on the fixed frame 23, and a half gear 28 is fixedly sleeved on the rotating shaft 27, and the half gear 28 is respectively meshed with the two tooth plates 26, and a driving motor 29 is fixedly installed on the front of the fixed frame 23, and the rotating shaft 27 passes through the fixed frame 23 and is fixedly connected to the output shaft of the driving motor 29, and a cutter 30 is fixedly installed on the bottom of the rectangular moving block 25.

[0039] When shearing, the driving motor 29 is started, the driving motor 29 drives the rotating shaft 27 to rotate, the rotating shaft 27 drives the half gear 28 to rotate, the half gear 28 drives the rectangular moving block 25 to descend under the action of the two tooth plates 26, and the rectangular moving block 25 drives the cutter 30 to descend.

[0040] like Figure 2 As shown, the shearing mechanism 02 also includes two limit slide bars 31 fixedly mounted on the back of the fixed frame 23 , the two limit slide bars 31 both pass through the cutter 30 and are slidably connected to the cutter 30 , and the bottom ends of the two limit slide bars 31 are fixedly connected to the supporting platform 1 .

[0041] During the movement of the cutter 30, the cutter 30 is limited by the limiting slide bar 31 to ensure that when the cutter 30 shears the metal plate, the cutter 30 and the supporting platform 1 are closely lowered for shearing, thereby effectively protecting the cutter 30 and preventing the cutter 30 from shaking during shearing and causing damage to the cutter 30.

[0042] like Figure 6As shown, the shearing mechanism 02 also includes two adjustment plates 32 respectively fixedly mounted on the bottom of the two fixed blocks 13, and the bottom ends of the several adjustment plates 32 are respectively hingedly mounted with adjustment telescopic rods 33, and two adjustment slots 331 are respectively provided on the two connecting plates 11, and the ends of the several adjustment telescopic rods 33 respectively extend into the several adjustment slots 331 and are respectively fixedly connected to the several adjustment slots 331, and the several adjustment telescopic rods 33 are respectively wound with springs 2 35, and the front ends of the several springs 2 35 are respectively fixedly connected to the connection points of the several adjustment telescopic rods 33, and the ends of the several springs 2 35 are respectively fixedly connected to the several adjustment slots 331.

[0043] The grinding plate 14 will push the adjusting plate 32 to move during the descending process, and the adjusting plate 32 will push the adjusting telescopic rod 33 to move into the adjusting slot 331. When the cutter 30 descends to the lowest point, the grinding plate 14 will fit the inclined surface of the cutter 30 under the thrust of the spring 2 35. At the same time, the thrust of the spring 2 35 will also increase the fit between the grinding plate 14 and the inclined surface of the cutter 30, thereby improving the grinding fineness.

[0044] like Figure 7 and Figure 8 As shown, a pushing mechanism 03 is respectively provided on the two fixed blocks 13, and the pushing mechanism 03 includes an L-shaped push rod 36 fixedly installed on the right side of the fixed block 13, and the end of the L-shaped push rod 36 extends to the outside of the bearing platform 1 and is slidably connected to the bearing platform 1, and an L-shaped movable plate 37 is fixedly installed on the end of the L-shaped push rod 36, and a telescopic slide rod 38 is slidably installed on the L-shaped movable plate 37, and the telescopic slide rod 38 passes through the L-shaped movable plate 37, and a spring 39 is wound on the telescopic slide rod 38, and an L-shaped mounting rod 40 is fixedly installed on the right side of the bearing platform 1, and a disc 41 is rotatably installed on the L-shaped mounting rod 40, and a plurality of curved teeth 43 are fixedly installed on the outer wall of the disc 41.

[0045] When the fixed block 13 approaches the transmission plate 16, the fixed block 13 simultaneously drives the L-shaped push rod 36 to move, the L-shaped push rod 36 drives the L-shaped movable plate 37 to move, and the L-shaped movable plate 37 drives the telescopic slide rod 38 to move. The telescopic slide rod 38 will push the corresponding curved teeth 43 to move, and the curved teeth 43 drive the disc 41 to rotate. When the cutter 30 rises, the telescopic slide rod 38 will move to the side away from each other. When the telescopic slide rod 38 contacts the curved teeth 43, it will shrink again and return to the outside of the disc 41. When the telescopic slide rod 38 leaves the curved teeth 43, the telescopic slide rod 38 will rebound again under the action of the spring three 39, so that the telescopic slide rod 38 is restored to the longest state to facilitate the next time to drive the curved teeth 43 to rotate.

[0046] like Figure 2 and Figure 8As shown, the pushing mechanism 03 also includes an annular groove 44 provided on the L-shaped mounting rod 40, in which a plurality of pushing telescopic rods 45 are fixedly installed, and at the ends of the plurality of pushing telescopic rods 45, pushing rubber blocks 46 are fixedly installed, and four springs 47 are respectively wound around the plurality of pushing telescopic rods 45, and the ends of the plurality of springs 47 that are close to each other are fixedly connected to the annular groove 44, and the ends of the plurality of springs 47 that are far away from each other are fixedly connected to the plurality of pushing rubber blocks 46, and a material storage trough 48 is provided on the top of the supporting platform 1.

[0047] The disc 41 drives the telescopic rod 45 to rotate, and the telescopic rod 45 drives the pushing rubber block 46 to rotate. After the pushing rubber block 46 contacts the sheared metal plate, it will shrink under the action of the spring four 47. At the same time, the spring four 47 will also give the pushing rubber block 46 a force to push outward, so that the pushing rubber block 46 will be closer to the sheared metal plate and at the same time increase the friction between the pushing rubber block 46 and the sheared metal block. As the two pushing rubber blocks 46 corresponding to the left and right sides of the supporting platform 1 rotate at the same time, the sheared metal plate will be pushed to move backward and pushed into the storage trough 48, so as to avoid the sheared metal plate blocking and affecting the shearing work of the metal plate behind, thereby reducing labor and effectively improving the shearing efficiency.

[0048] When in use, the drive motor 29 is started, the drive motor 29 drives the rotating shaft 27 to rotate, the rotating shaft 27 drives the half gear 28 to rotate, the half gear 28 drives the rectangular moving block 25 to descend under the action of the two toothed plates 26, and the rectangular moving block 25 drives the cutter 30 to descend. After the cutter 30 shears the metal plate, the plane of the cutter 30 will contact the movable plate 20, and the movable plate 20 will be pushed into the grinding chamber 18 under the action of the inclined surface of the movable plate 20. At this time, the springs on the plurality of telescopic rods 19 are 21 will generate an outward thrust, and when the cutter 30 continues to move downward, it will contact the spring-grinding plate 22 on the back of the movable plate 20. The grinding plate 22 will continue to grind the plane of the cutter 30 under the thrust of the telescopic rod 19 to avoid burrs and unevenness on the cut surface of the metal plate after shearing; when the cutter 30 descends to cut the metal plate, the metal plate contacts the grinding plate 14 and presses the grinding plate 14 downward, and the grinding plate 14 drives the fixed block 13 to descend , the fixed block 13 drives the T-shaped telescopic connecting block 15 to descend, the T-shaped telescopic connecting block 15 drives the transmission plate 16 to descend, the transmission plate 16 drives the Z-shaped plate 5 to descend, the Z-shaped plate 5 squeezes the gas in the L-shaped air chamber 4, the gas enters the air box 6 through the gas delivery hole 7 and then pushes the piston plate 8 to move in the direction of the transmission plate 16, the piston plate 8 drives the push plate 9 to move, the push plate 9 drives the moving block 10 to move, the moving block 10 drives the connecting plate 11 to move, the connecting plate 11 drives the hinged plate 12 to move in the direction of the transmission plate 16, the hinged plate 12 drives the T-shaped telescopic connecting block 15 to slide and descend in the direction of the transmission plate 16, the T-shaped telescopic connecting block 15 drives the fixed block 13 and the grinding plate 14 to move in the direction of the transmission plate 16, the two grinding plates 14 grind the inclined surface of the cutter 30 in the process of approaching each other, so as to avoid the inclined surface of the cutter 30 becoming blunt due to time of use and affecting the shearing quality, so as to make the grinding of the cutter 30 more comprehensive, and ensure that the cutter 30 is in a normal sharp state when shearing the metal plate;

[0049] In the process of the fixed block 13 approaching the transmission plate 16, the fixed block 13 simultaneously drives the L-shaped push rod 36 to move, the L-shaped push rod 36 drives the L-shaped moving plate 37 to move, and the L-shaped moving plate 37 drives the telescopic slide bar 38 to move, and the telescopic slide bar 38 will push the corresponding curved teeth 43 to move, and the curved teeth 43 drive the disc 41 to rotate, and the disc 41 drives the telescopic rod 45 to rotate, and the telescopic rod 45 drives the pushing rubber block 46 to rotate. After the pushing rubber block 46 contacts the sheared metal plate, it will shrink under the action of the spring four 47. At the same time, the spring four 47 will also give the pushing rubber block 46 a force to push outward, so that the pushing rubber block 46 will be closer to the sheared metal plate and at the same time increase the friction between the pushing rubber block 46 and the sheared metal block. As the two pushing rubber blocks 46 corresponding to the left and right sides of the bearing platform 1 rotate at the same time, the sheared metal plate will be pushed to move backward, and the sheared metal plate will be pushed into the storage trough 48 to avoid the sheared metal plate blocking and affecting the shearing work of the metal plate behind.
