Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel polishing, and particularly relates to a polishing device and a polishing method for steel. BACKGROUND

[0002] In the field of steel processing, steel polishing is an important pretreatment process of the subsequent processing link of welding, painting and assembly. Through polishing, the steel surface can reach the precision requirements of flatness and smoothness, and the steel surface cleanliness and the adhesion of subsequent processing are improved, thereby ensuring the quality and service life of the final product. At present, the steel polishing operation is mostly completed by manual polishing. The specific operation process is as follows: the operator first carries the steel to be polished to the designated work area, preliminarily positions the steel by manually holding or a simple clamp of a temporary fixing frame and a clamping block to avoid large shaking during polishing; then the operator holds the polishing tool of an angle grinder, a grinding machine or a hand-held belt sander, adjusts the tool angle and force according to the actual situation of the steel surface, and gradually polishes the surface along the length or circumference of the steel; the operation needs to be frequently paused during polishing to observe the polishing effect and judge whether there is a problem of missed polishing, excessive polishing or uneven surface, and the polishing path and operation parameters are adjusted in time; after the polishing operation is completed, the operator manually carries the steel from the work area to the discharge stacking area, and manually sweeps and collects the metal scraps generated during polishing to facilitate subsequent processing.

[0003] However, the existing manual polishing method has many drawbacks: first, the positioning accuracy of manual polishing completely depends on the experience and hand feeling of the operator, and manual holding or a simple clamp cannot realize stable horizontal and vertical positioning of the steel, and the steel is prone to deviation, warping or rotation during polishing, which causes uneven surface polishing, and problems of incomplete removal of local impurities or excessive polishing leading to steel loss, and cannot guarantee the uniformity of polishing quality; second, manual polishing requires the operator to hold the tool throughout the operation, and needs to frequently complete the operations of steel carrying, tool angle adjustment and polishing effect observation, the polishing cycle of a single steel is long, the overall operation efficiency is low, and it is difficult to meet the production demand of batch processing; third, the metal scraps generated during manual polishing lack an effective automatic collection path, and are scattered in the work area, which not only requires additional manpower for cleaning, but also the scattered scraps are easy to adhere to the polishing tool or the steel surface, further affecting the polishing accuracy; fourth, manual polishing has high skill requirements for the operator, and there are obvious differences in the operation method and force control of different operators, which leads to poor consistency of the polishing effect of the same batch of steels, and the operator is prone to physical fatigue after holding the polishing tool for a long time, greatly increasing the probability of operation errors and safety accidents; fifth, for steels of different diameters and lengths, the steel holding method and clamp structure need to be adjusted during manual polishing, the adaptability is poor, and it takes a long time to replace the polishing tool or adjust the operation parameters, which also consumes a lot of physical strength of the operator.

[0034] In this embodiment, when using the steel grinding equipment, the steel 500 is first placed at the feeding section 2 of the feeding mechanism 1. Then, the power box 88 is started, and the power box 88 drives the screw 87 in the drive box 86 to rotate, which drives the extension block 85 and the push plate 79 to move. The rotating ball 77 at the front end of the push rod 75 contacts the steel 500 and pushes it along the feeding section 2 to the grinding section 3. During this process, the guide plate 80 slides along the guide rod 51 through the ball 82 in the through hole 81 to improve the smoothness of the guide. The steel 500 moves forward at the mounting groove 13 of the feeding section 2 by the rolling of the auxiliary wheel 11. The rubber layer 12 on the outer surface of the auxiliary wheel 11 can reduce friction and prevent the steel from being scratched. The guide rod 51 is fixed on the feeding mechanism 1 by the positioning block 83 and is located above the collection trough 16.

[0035] When the steel 500 enters the grinding section 3, the positioning motor 29 is started, which drives the positioning cylinder 28 to rotate. The diameter of the positioning cylinder 28 is adapted to the steel 500, achieving lateral limitation while moving the steel towards the discharge section 5. If it is necessary to adapt to steel of different diameters, the extension seat 33 on the fixing seat 35 can be removed by screws and the positioning cylinder 28 of the corresponding specification can be replaced. The inner cylinder 30 of the positioning cylinder 28 is connected to the outer cylinder 31 through the connecting piece 32, and both ends are rotatably connected to the extension seat 33. At the same time, the lifting cylinder 53 pushes the lifting plate 38 to rise and fall along the guide rod 51 to adjust the height of the positioning cylinder 28. The limit cover 52 at the upper end of the guide rod 51 and the buffer rubber ring at the lower end can prevent the lifting plate 38 from rigidly colliding. The collection frame 39 on the lifting plate 38 can collect the grinding debris at the lateral feeding limit mechanism 7. The protective plate 36 between the positioning motor 29 and the positioning cylinder 28 can prevent debris from splashing and personnel from accidentally touching it.

[0036] Next, the adjusting cylinder 62 of the longitudinal limiting mechanism 8 is activated, pushing the limiting seat 63 to move downward along the guide rail 71. The guide seat 70 on the inner side of the limiting seat 63 slides along the guide rail 71 to ensure smooth movement. The pulley 69 of the limiting member 65 contacts the upper end of the steel 500 to achieve longitudinal limiting and prevent the steel from warping during grinding. The limiting member 65 is connected to the pulley frame 68 through the connecting column 66, the arc-shaped section 67a of the connecting rib 67 and the connecting section 67b. The pulley 69 is rotatably mounted on the pulley frame 68. The protective door 100 between the mounting seats 60 is equipped with a limit switch. When it is opened, the equipment automatically stops to improve safety. The protrusion 60a of the mounting seat 60 is fixed to the guide rail 71 through the reinforcing plate 72. The top plate 61 connects the two mounting seats 60 and supports the adjusting cylinder 62.

[0037] Subsequently, the grinding motor 58 inside the positioning box 27 starts, and the drive wheel at its output end passes through the opening 55 of the grinding section 3 of the conveying mechanism 1 and the through hole 56 of the positioning box 27 via the transmission belt 59, driving the driven wheel 57 on the drive shaft 18 to rotate. The drive shaft 18 and the driven shaft 19 rotate synchronously, and their two ends are rotatably connected to the inside of the support plate 20. The support plate 20 is detachably connected to the conveying mechanism 1 via the connecting block 21. The reinforcing member 22 at the angle between the connecting block 21 and the support plate 20 enhances the structural stability. The rotating wheel 23 on the drive shaft 18 and the driven shaft 19 drives the grinding belt 26 to rotate, grinding the surface of the steel 500. The grinding belt 26 can be a silicon carbide sand belt or an alumina sand belt, and a tension adjustment component can also be set to prevent slippage.

[0038] The grinding debris slides into the collection trough 16 through the inclined guide surface 15 at the bottom of the mounting groove 13, and finally collects in the collection tray 17. The feeding section 2, grinding section 3, and discharge section 5 of the conveying mechanism 1 are integrally formed structures, all set on the base 10 to ensure overall stability. The ground steel 500 enters the discharge section 5 under the drive of the positioning cylinder 28 and the pushing mechanism 9, and finally slides out through the inclined guide surface 90 of the receiving platform 89, completing the entire grinding process.
