Description

Technical Field

[0001] This utility model relates to the field of industrial processing technology, and in particular to an automated grinding equipment for square and rectangular tubes. Background Technology

[0002] Rectangular and square tubes are a type of steel material, referring to hollow steel tubes with a rectangular or square cross-section. Based on the cross-sectional shape, they are divided into square tubes (square cross-section) and rectangular tubes (rectangular cross-section). These steel tubes are typically manufactured by rolling steel plates or strips into tubular shapes and then welding the seams. Rectangular and square tubes are widely used in building structures, machinery manufacturing, and steel structure engineering. Due to their good load-bearing capacity and torsional strength, they are often used in supporting components, frame structures, and other structures requiring load-bearing capacity. The size and thickness of rectangular and square tubes can be customized to meet different needs, thus offering great flexibility in practical applications. Common manufacturing processes include hot rolling, cold rolling, and cold drawing; the specific process selection usually depends on the final application requirements and material properties.

[0003] For example, a Chinese patent discloses an automated grinding equipment for square and rectangular tubes (patent number: CN217596639U). This equipment, consisting of a right-side grinding unit, an upper-side grinding unit, a drive and clamping mechanism, and a left-side grinding unit, can simultaneously grind multiple sides of square and rectangular tubes. The drive and clamping mechanism clamps and drives the tubes. Particles generated during grinding fall into a particle collection hopper for collection. The bottom of the particle collection hopper has a movable collection frame, facilitating waste removal by employees. This effectively reduces labor costs, increases productivity, and improves employee workload and working conditions.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: as mentioned above, the device can only perform simple grinding on rectangular tubes. The grinding mechanism is fixed inside the device, the grinding speed is slow, and uneven grinding may occur due to speed differences. Summary of the Invention

Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problems mentioned above, which are that the device can only perform simple grinding of rectangular tubes, the grinding mechanism is fixed inside the device, the grinding speed is slow, and uneven grinding may occur due to speed differences. The overall idea is as follows: An automated grinding device for rectangular tubes includes a square cover 11, a support plate 12 is fixedly installed at the bottom of the square cover 11, and a grinding mechanism is provided inside the support plate 12. The grinding mechanism includes a first rotating column 13, a first synchronous belt drive assembly 14, a second rotating column 15, a grinding belt 23, a first gear 24, a rack 25, and a first push plate 26.

A connecting pipe 34 is fixedly installed on the side wall of the collection frame 33 to facilitate the removal of dust from inside the collection frame 33 and prevent dust from being generated.

[0028] To address the problems existing in the prior art, this utility model provides an automated grinding device for rectangular tubes. A cylinder 28 drives a pneumatic rod 29 to move from front to back, which in turn drives a second push plate 31 to move from front to back. The second push plate 31 pushes the rectangular tube into the square cover 11. A motor drives a second rotating column 15 to rotate counterclockwise, which in turn drives a first synchronous belt drive assembly 14 to rotate counterclockwise.

The rectangular tube and the grinding belt 23 move relative to each other. This relative movement helps the grinding belt 23 to act more evenly on the surface of the rectangular tube, reducing uneven grinding caused by speed differences and improving grinding efficiency. When the grinding belt 23 grinds the protective tube, the first rotating column 13 drives the first bevel gear 16 to rotate counterclockwise, the first bevel gear 16 drives the second bevel gear shaft 17 to rotate clockwise, the second bevel gear shaft 17 drives the third bevel gear 18 to rotate counterclockwise, the third bevel gear 18 drives the third rotating column 19 to rotate counterclockwise, and the third rotating column 19 drives the rotating blade 21 to rotate counterclockwise. The rotating blade 21 sucks the dust inside the square cover 11 into the collection frame 33 through the bearing plate 12, and then sucks the dust out of the collection frame 33 through the connecting pipe 34, thereby effectively improving the working environment of the employees.

[0029] Working principle:

[0030] First, the rectangular tubes are stacked and placed inside the placement frame 27. The cylinder 28 is activated, causing the pneumatic rod 29 to move from front to back. The pneumatic rod 29 then moves the second push plate 31 from front to back, pushing the rectangular tubes into the square cover 11. The motor is then activated, causing the second rotating column 15 to rotate counterclockwise. The second rotating column 15 drives the first synchronous belt drive assembly 14 counterclockwise, which in turn drives the first rotating column 13 to rotate counterclockwise. The first rotating column 13 and the first synchronous belt drive assembly 14 then drive the grinding belt 23 counterclockwise. The first rotating column 13 and the second rotating column 15 drive the first gear 2... 4. Rotate counterclockwise, and the rack 25 meshes with the first gear 24, causing the rack 25 to move from right to left inside the square cover 11, pushing the rectangular tube to the side wall of the grinding belt 23 for grinding. The grinding direction is opposite to the movement of the rectangular tube. After grinding, the rectangular tube will push open the baffle 32 and extend out from inside the square cover 11. Since the rectangular tube and the grinding belt 23 are moving relative to each other, the relative speed of grinding can be increased. The higher the relative speed, the larger the surface area ground per unit time, thereby improving the grinding efficiency. Moreover, the relative movement can help the grinding belt 23 to act more evenly on the surface of the rectangular tube, reducing the uneven grinding caused by speed differences.

[0031] In the second step, when the grinding belt 23 grinds the protective tube, the first rotating column 13 drives the first bevel gear 16 to rotate counterclockwise, the first bevel gear 16 drives the second bevel gear shaft 17 to rotate clockwise, the second bevel gear shaft 17 drives the third bevel gear 18 to rotate counterclockwise, the third bevel gear 18 drives the third rotating column 19 to rotate counterclockwise, the third rotating column 19 drives the rotating blade 21 to rotate counterclockwise, and the rotating blade 21 sucks the dust inside the square cover 11 into the collection frame 33 through the bearing plate 12, and then sucks away the dust inside the collection frame 33 through the connecting pipe 34, thereby effectively improving the working environment of the employees.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
