A strip steel deburring device

Abstract

The present application belongs to the technical field of deburring processing, in particular to a strip steel deburring device. The device comprises a box, a guide roller, a slide column, a straight rack, a driving gear, a No.1 motor, a longitudinal beam, a cross beam and abrasive sand. The strip steel passes through the top of the box. At this time, the driving structure is in a relaxed state. The No.1 motor drives the driving gear to rotate, which drives the straight rack and the slide column to slide downward, pushes the longitudinal beam and the cross beam to move downward, and pushes the strip steel inside the box to move downward, so that the strip steel is bent along the guide rollers on both sides and immersed in the abrasive sand inside the box. The driving structure clamps and conveys the strip steel, so that the strip steel passes through the abrasive sand inside the box at a constant speed. The abrasive sand grinds and removes the burrs on both sides of the strip steel, thereby improving the neatness of the side edges of the strip steel, reducing the probability of blockage of the strip steel and the stamping die, improving the quality of the stamped workpiece, and providing safety for stamping processing.

Description

Technical Field

[0001] The invention belongs to the technical field of deburring processing, in particular to a strip steel deburring device. Background Art

[0002] Strip steel is a thin, narrow, and long steel plate produced to meet diverse production and processing requirements. Strip steel is generally supplied in coils and has the advantages of high dimensional accuracy, good surface quality, ease of processing, and material savings. It is widely used in the manufacture of welded pipes, clamps, washers, springs, and various sheet-like workpieces.

[0003] When processing steel strips to manufacture workpieces, stamping machines are usually used in conjunction with various stamping dies to perform stamping. After the steel strips are transported to the processing workshop by transport vehicles, they are transported to the storage area by cranes and forklifts for storage. During processing, they are lifted by cranes to the material racks of the stamping equipment. The steel strips pass through the conveying equipment and the stamping dies of the stamping equipment for continuous stamping processing.

[0004] During the production, transportation and storage of strip steel, deformation and burrs may occur on the edge of the strip steel. Although the stamping equipment has a shaping function, it can only press the edge of the strip steel down and flatten it, but cannot remove the burrs on the edge of the strip steel. The burrs on the edge of the strip steel will cause the strip steel to pass through the stamping die, causing the conveying of the strip steel to be misaligned, thereby causing the stamping workpiece to be misaligned. It may even cause the strip steel to bend and stack on the stamping die, causing damage to the stamping die.

[0047] Afterwards, the drive structure is in a relaxed state for the steel strip 11, and the No. 1 motor 8 drives the drive gear 7 to rotate, driving the support rack 6 and the slide column 5 to slide downward, pushing the longitudinal beam 9 and the cross beam 10 to move downward, pushing the steel strip 11 inside the box body 1 to move downward, so that the steel strip 11 bends along the guide rollers 2 on both sides, and the steel strip 11 is immersed in the grinding sand inside the box body 1; the longitudinal beam 9 and the cross beam 10 move downward, driving the mounting plate 16 and the long folding plate 17 to move downward, so that the long magnet 20 at the bottom of the rubber baffle 19 approaches the long magnet 20 on the inner wall of the box body 1, so that the two long magnets 20 are attracted to each other, driving the bottom of the rubber baffle 19 to be fixed to the inner wall of the box body 1;

[0048] The drive structure clamps and conveys the steel strip 11, so that the steel strip 11 passes through the abrasive sand inside the box 1 at a uniform speed; at the same time, the second motor 13 drives the pulley 12 to rotate, and the drive belt 14 rotates and moves around the two pulleys 12, driving the elastic push plate 15 to move, pushing the abrasive sand inside the box 1 to rotate and move; the abrasive sand is blocked and guided by the long folding plate 17 and the rubber baffle 19, so that the friction force and friction rate between the two sides of the steel strip 11 and the abrasive sand are increased; the abrasive sand grinds and removes burrs on both sides of the steel strip 11, thereby improving the neatness of the side edges of the steel strip 11, reducing the probability of obstruction between the steel strip 11 and the stamping die, improving the quality of the stamped workpiece, and ensuring the safety of the stamping process;

[0049] When the steel strip 11 moves through the box body 1, the steel strip 11 contacts and moves with the guide roller 2, driving the guide roller 2 to rotate, driving the rubber wheel 29 to rotate, and the two rubber wheels 29 are squeezed and contacted, causing the two rubber wheels 29 to rotate, driving the rotating rod 28 to rotate, driving the fixing ring 30 and the rubber elastic rod 31 to rotate, and driving the knocking ball 32 to knock the bottom surface of the steel strip 11, causing the steel strip 11 to vibrate, and shaking off the abrasive sand on the surface of the steel strip 11; the two sides of the steel strip 11 pass through the concave surfaces of the chamfering concave wheels 34 on both sides, so that the two sides of the steel strip 11 are polished into arc chamfers, thereby improving the smoothness of the edge of the steel strip 11 and improving the smoothness of the steel strip 11 entering the stamping die; at the same time, the high-pressure air pump generates high-pressure airflow, which is sprayed to the top surface and the ground of the steel strip 11 through the double-headed nozzle 38, cleaning the surface of the steel strip 11 and improving the cleanliness of the steel strip 11; thereby reducing the probability of the steel strip 11 bringing abrasive sand into the stamping die and reducing the probability of damage to the stamping workpiece.
