Description

Technical Field

[0001] The invention relates to the technical field of sheet metal processing, in particular to a sheet metal scraping device for a scraper with a positioning mechanism. Background Art

[0002] The scraper blade is a key component on the scraper, located at the front of the scraper bucket. It is the main working surface for cutting and moving soil, sand, gravel and other materials. The scraper blade is usually made of high-strength, wear-resistant steel to ensure its durability and life under harsh working conditions. The scraper blade is usually manufactured by sheet metal processing.

[0003] The existing sheet metal processing will have positioning misalignment during operation, and the punching position cannot be adjusted reasonably, resulting in the position deviation and distance deviation during punching, resulting in additional processing steps, increased work steps, and reduced work efficiency. The scraper blade, as a metal material, will generate high temperature during the punching process. Continuous friction and heat will cause material deformation and tool wear, increasing processing costs. After the punching is completed, the generated debris, burrs, chamfers, etc. will affect the subsequent processing and assembly accuracy, and are extremely easy to scratch. The metal that has lost the oxide layer after grinding is extremely easy to rust, oxidize and corrode. For this reason, we propose a scraper sheet metal scraping device with a positioning mechanism.

The height of the scraper blade 3 is fixed, and the sliding bar 721 slides upward under the force, pulling open the third spring 724, so that the second feed port 722 slides into the L-shaped discharge pipe 720, so that the lubricating oil in the lubricating oil tank 717 passes through the second feed port 722 and enters the L-shaped discharge pipe 720 to be output to the second sleeve 75 outside the first sleeve 74. After the punching is completed, the sliding bar 721 is staggered with the scraper blade 3, and the return force of the third spring 724 pulls the sliding bar 721 downward, so that the second feed port 722 is separated from the L-shaped discharge pipe 720, and the limit rod 723 limits the position of the sliding bar 721 to stop the output of the lubricating oil.

The four groups of second springs 714 are fixedly connected to the arc polishing sheet 715 at one end away from each other, one end of the second spring 714 is fixedly connected to the second connecting shaft 712, and the other end of the second spring 714 is fixedly connected to the arc polishing sheet 715.

[0050] Specifically, the boring blade 716 drills a hole in the scraper blade 3 downward, and the second connecting shaft 712 moves downward together with the boring blade 716. The arc surface grinding sheet 715 contacts the edge of the hole and grinds it by rotating, and then continues to move downward. After the arc surface grinding sheet 715 is subjected to pressure, the second slide bar 713 slides into the second connecting shaft 712 and presses the second spring 714, so that the arc surface grinding sheet 715 cleans the debris in the hole, and then the arc surface grinding sheet 715 misses the hole and reaches the outside of the hole of the scraper blade 3. The second spring 714 opens, so that the arc surface grinding sheet 715 grinds the inner edge of the hole at the lower end of the scraper blade 3.

[0051] Working principle: when in use, place the scraper blade 3 on the upper end of the conveyor belt 2, start the conveyor belt 2 to transport the scraper blade 3 to the placement groove 11 to the specified position, start the cylinder 4, and the output shaft of the cylinder 4 drives the mounting block 51 to slide on the outer side of the third slide bar 9, and slides in the second slide groove 10 through the roller 518 to reduce the friction, so that the mounting block 51 reaches the specified position, and starts the first motor 55 installed on the upper end of the support frame 54 to rotate a group of first gears 58, and a group of first gears 58 drives a group of first rotating rods 52 at the lower end to rotate, and the outer side of a group of first gears 58 drives another group of first gears 58 to rotate through the first chain 57, so that the first rotating rods 52 at the lower end of the other group of first gears 58 are synchronized. Rotate, the two groups of first rotating rods 52 drive the first lifting block 56 to move up and down through the threads, the first lifting block 56 drives the second lifting block 59 at the front end and the limit frame 519 on one side to move, the limit frame 519 drives the third gear 514 to slide outside the third rotating rod 515, start the second motor 517 to rotate the third rotating rod 515, the third rotating rod 515 drives the third gear 514 to rotate through the clamping strip 516, the third gear 514 meshes and rotates the second gear 513 to rotate, the second gear 513 drives the second rotating rod 511 to rotate in the first sliding groove 510, the second rotating rod 511 drives the slider 512 to move left and right through the threads, so that the punching mechanism 7 can move left and right to adapt to the size of the scraper blade 3;

[0052] When the scraper blade 3 is placed, the upper and lower ends are between the two groups of first bevel gears 66. When the first rotating rod 52 rotates, the fourth gear 61 is driven to rotate, and the fourth gear 61 drives the fifth gear 63 to rotate through the second chain 62. The fifth gear 63 is fixed in position by the L-shaped fixing rod 64. The fifth gear 63 drives a group of first bevel gears 66 to rotate, a group of first bevel gears 66 drives the second bevel gear 68 to rotate, and the second bevel gear 68 drives another group of first bevel gears 66 to rotate. When the two groups of first bevel gears 66 rotate, the scraper blade 3 is polished by the polishing block 67 to avoid burrs on the scraper blade 3 after processing and to avoid scratches on the hands when taking out the scraper blade 3. When the scraper blade 3 moves toward the polishing mechanism 6, it first contacts the guide bar 613, and the guide bar 613 moves toward the anti-rust paint box 6 9 slides and compresses the first spring 611, so that the first feed port 616 passes through the baffle 615 and enters the anti-rust paint box 69, so that the anti-rust paint in the anti-rust paint box 69 enters the first discharge pipe 610 and is output outward at the grinding position of the scraper blade 3 to prevent the surface of the metal oxide layer from rusting after grinding. When the first discharge pipe 610 rotates, it drives the blade 614 to rotate, and a certain airflow is formed in the mounting ring 612 to clean the outer wall of the grinded scraper blade 3, and quickly dry the anti-rust paint, and then the cross connecting rod 618 is driven by the limit plate 617 to stir the inside of the anti-rust paint box 69 to prevent the anti-rust paint from settling. After the scraper blade 3 is detached, the first discharge pipe 610 is reset when the first spring 611 is opened, and the limit plate 617 fits with the baffle 615 to limit the position of the first discharge pipe 610 to avoid dislocation;

[0053] After the slider 512 drives the second mounting bracket 71 to the specified position, the third motor 72 is started to rotate the first connecting shaft 73, and the first connecting shaft 73 drives the fixed rotating shaft 78 to rotate. When the fixed rotating shaft 78 rotates, it drives the first sliding rod 79 to rotate. The first sliding rod 79 slides in the guide groove 711, and the height difference of the guide groove 711 is used to make the sliding rod 710 move up and down. The sliding rod 710 drives the second connecting shaft 712 to move up and down, so that the second connecting shaft 712 and the boring blade 716 can move up and down repeatedly while rotating, and the hole is drilled and polished back and forth to avoid metal fatigue of the boring blade 716. The boring blade 716 is adjusted by the movement of the adjustment mechanism 5. The scraper blade 3 is drilled, and the boring blade 716 drills the scraper blade 3 downward. The second connecting shaft 712 moves downward together with the boring blade 716, and the arc surface grinding sheet 715 contacts the edge of the hole and grinds it by rotation, and then continues to move downward. After the arc surface grinding sheet 715 is subjected to pressure, the second slide bar 713 slides into the second connecting shaft 712, and the second spring 714 is pressed, so that the arc surface grinding sheet 715 cleans the debris and removes the burrs in the hole, and then the arc surface grinding sheet 715 staggers the hole and reaches the outside of the scraper blade 3 hole, and the second spring 714 opens, so that the arc surface grinding sheet 715 grinds the inner edge of the hole at the lower end of the scraper blade 3;

[0054] The sliding bar 721 moves downward with the third motor 72, and the sliding bar 721 contacts the upper end of the scraper blade 3 and continues to press downward. The height of the scraper blade 3 is fixed, and the sliding bar 721 slides upward under the force, pulling the third spring 724, so that the second feed port 722 slides into the L-shaped discharge pipe 720, so that the lubricating oil in the lubricating oil tank 717 passes through the second feed port 722 and enters the L-shaped discharge pipe 720 to be output to the second sleeve 75 outside the first sleeve 74, so that the lubricating oil enters the buffer groove 76, and the first sleeve 74 prevents the second sleeve from being driven when the first connecting shaft 73 rotates 75 rotates, and then the buffer groove 76 is used as a buffer to store the lubricating oil, and then it flows downward through the lower sliding hole 719, and then it is guided by the guide groove 77 and output downward, so that the second connecting shaft 712 and the boring blade 716 can be cooled and lubricated, and the drilled hole can be maintained to avoid oxidation and rust. After the drilling is completed, the sliding bar 721 is staggered with the scraper blade 3, and the return force of the third spring 724 pulls the sliding bar 721 downward, so that the second feed port 722 is separated from the L-shaped discharge pipe 720, and the limit rod 723 limits the position of the sliding bar 721 to stop outputting the lubricating oil.
