Description

Technical Field

[0001] The present invention relates to the technical field of metal processing, in particular to a metal material cutting and severing device for processing mining machinery parts. Background Art

[0002] In mining production systems, the scraper of an apron conveyor, a core component of material transportation, endures the intense friction and impact of materials such as ore and coal. Its geometric accuracy and edge quality directly impact conveying efficiency and safety. Traditional scrapers are often manufactured from high-hardness, wear-resistant steel and undergo multiple independent processes, including stamping, cutting, edge grinding, mounting hole machining, and blanking.

[0003] However, existing production technology has significant shortcomings: First, the sheet metal must be clamped and transferred to different equipment for processing multiple times. In particular, the secondary cutting after stamping can easily cause contour misalignment, resulting in mismatched mounting holes between the scraper and the conveyor chain, causing the scraper to jam or abnormal chain wear during operation. Second, the stamped scraper has sharp burrs on the sides and corners, requiring workers to grind them with handheld grinders. This is not only inefficient but also lacks consistency. Residual burrs can easily scratch operators and may accelerate equipment wear during transportation. Third, the formed scraper is often manually removed from the mold, interrupting the continuous production cycle. The high-hardness steel is heavy, increasing labor intensity and posing safety risks. To this end, we propose a metal material cutting and shearing device for processing mining machinery parts. Summary of the Invention

A first servo motor 1007 is fixedly mounted on the outer wall of the other side of the slider 1005. The output end of the first servo motor 1007 is fixedly connected to the first sleeve 1006. The end of the slider 1005 is also slidably connected to an elastically retractable second sleeve 1008. The end of the second sleeve 1008 is fixedly mounted with a connecting plate 1009. The outer wall of the connecting plate 1009 is fixedly mounted with a clamping block 1010. A lever sensor 1011 is fixedly mounted on the inner wall of the middle section of the slide 1004.

When the slider 1005 is at the end of the slide 1004 with the first movable groove 1002, the first servo motor 1007 drives the first sleeve 1006 to rotate, thereby causing the connecting plate 1009 fixed with the clamping block 1010 to rotate synchronously. At this time, the connecting plate 1009 is correspondingly in the first movable groove 1002. The inner wall of the first movable groove 1002 is inclined. When the connecting plate 1009 rotates to be perpendicular to the slide 1004, under the guidance of the inner wall of the first movable groove 1002, the second sleeve 1008 extends outward, thereby causing the clamping block 1010 to squeeze the side of the sheet material, and conveying The upper surface of the frame 1 is provided with clamping blocks 1010 on both sides of the plate. The plate is squeezed and fixed under the cooperation of the two clamping blocks 1010, and then the slider 1005 is driven to slide along the outer wall of the fixed frame 1001 by the fourth electric telescopic rod 20.

[0033] Working principle of the present invention: During use, the plate for processing the scraper on the plate conveyor is placed on the upper surface of the conveyor frame 1, and the plate is conveyed to the punching table 2 through the feeding assembly 10 provided on the conveyor frame 1. When the slider 1005 is at the end of the slide 1004 with the first movable groove 1002, the first servo motor 1007 drives the first sleeve 1006 to rotate, thereby causing the connecting plate 1009 fixed with the clamping block 1010 to rotate synchronously. At this time, the connecting plate 1009 is correspondingly in the first movable groove 1002, and the inner wall of the first movable groove 1002 is inclined. When the connecting plate 1009 rotates to be perpendicular to the slide 1004, under the guidance of the inner wall of the first movable groove 1002, the second sleeve 1008 extends outward, thereby causing the clamping block 1010 to move the side of the plate. The upper surface of the conveyor frame 1 is provided with clamping blocks 1010 on both sides of the plate. The plate is squeezed and fixed under the cooperation of the two clamping blocks 1010. Then, the slider 1005 is driven to slide along the outer wall of the fixed frame 1001 by the fourth electric telescopic rod 20. When the end of the plate is conveyed to contact the baffle provided on the upper surface of the punching table 2, the second electric telescopic rods 1301 provided on both sides are extended and retracted to correct and fix the position of the end of the plate so that the plate is set directly below the upper die 8. At this time, the connecting plate 1009 moves from the first movable groove 1002 to the second movable groove 1003. A pressure sensor is provided inside the second movable groove 1003. The first sleeve 1006 squeezes the pressure sensor to transmit an electrical signal to the controller (CPM1A). At the PLC controller), under the control of the controller, the hydraulic drive structure 6 drives the movable plate 7 to move downward, so that the upper die 8 set on the bottom surface of the movable plate 7 is downwardly cooperated with the lower die groove 3 to punch the plate into shape. The lower end of the cutter 9 is lower than the lowest point of the upper die 8. Before the upper die 8 punches, the cutter 9 set on the side of the movable plate 7 first cuts the plate. At this time, the first sleeve 1006 is driven by the first servo motor 1007 to rotate so that the connecting plate 1009 is rotated to be parallel to the slide groove 1004. The inner wall of the second movable groove 1003 is also inclined. In the guide of the inclined inner wall When the connecting plate 1009 is rotated to be parallel to the slide groove 1004, the elastic force of the first spring 1012 causes the second sleeve 1008 to retract into the inside of the first sleeve 1006, thereby causing the connecting plate 1009 to slide inside the slide groove 1004. At this time, the clamping block 1010 is separated from the side outer wall of the plate. When the fourth electric telescopic rod 20 drives the slider 1005 to move again to the first movable groove 1002, the first servo motor 1007 drives the connecting plate 1009 to repeat the above process, and the plate can be continuously transported to the punching table 2 for processing; After the sheet is punched and formed, the upper die 8 keeps squeezing the scraper after forming. At this time, the third electric telescopic rod 16 provided inside the punching table 2 can punch out a mounting hole on the sheet, so that the sheet can be installed on the conveyor belt and used in conjunction with the conveyor belt in the subsequent process. The interior of the upper die 8 is provided with a first clearance groove 18 used in conjunction with the punching head 17, and a material guide groove is provided through it. The waste punched out by the punching head 17 can be discharged through the inclined bottom surface of the material guide channel. During the process of conveying the plate to the punching table 2, the two side edges of the plate can be ground and chamfered respectively by the two sets of grinding assemblies 12, wherein the grinding wheel 1205 rotates continuously under the drive of the second servo motor 1204. During the conveying process, the two side edges of the plate are respectively in contact with the two high-speed rotating grinding wheels 1205. At the same time, the initial distance between the two grinding wheels 1205 is less than one to two centimeters of the width of the plate. When the plate passes between the two grinding wheels 1205, the two grinding wheels 1205 need to be squeezed to both sides respectively through the end of the plate. In this process, the two corners at the end of the plate can be ground by the two grinding wheels 1205. Under the action of the second spring 1207, the grinding wheel 1205 always keeps in contact with the outer wall of the plate to ensure the grinding effect on the side of the plate. When the plate is processed into a scraper and cut, the second mounting plate 1202 is pushed by the first electric telescopic rod 1201. The scraper moves forward. At this time, under the interaction force, the end of the scraper squeezes the two grinding wheels 1205 to the sides. At the same time, the grinding wheels 1205 can grind and chamfer the two corners of the scraper formed by cutting. The above process can grind the side edges and the corners at both ends of the scraper. When the slider 1005 moves from the second movable groove 1003 to the first movable groove 1002, the transmission rod 1101 fixedly connected to the connecting block 22 moves synchronously. During this process, under the meshing action of the rack plate 1102 and the gear 1107, the gear 1107 rotates. At the same time, under the action of the threaded transmission between the threaded sleeve 1108 and the threaded rod 1106, the push rod 1110 moves toward the inside of the lower die groove 3. The scraper after processing and forming can be pushed out of the lower die groove 3 by the push rod 1110 for unloading. When the slider 1005 moves from the first movable groove 1002 to the second support frame 1103 again to transport the plate, the rotation of the gear 1107 can make the push rod 1110 return to its initial position, and does not interfere with the cooperation between the upper die 8 and the lower die groove 3 to perform normal stamping of the plate.
