Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe manufacturing, in particular to a square pipe end grinding device. Background Art

[0002] Steel pipe refers to a steel material with a hollow cross-section whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it is divided into round, square, rectangular and special-shaped steel pipes. Rectangular steel pipes are also called "square pipes". The ends of square pipes are polished during the production and processing.

[0003] Authorization announcement number CN213646897U A large-diameter steel pipe processing device, specifically a large-diameter steel pipe end grinder. It is characterized in that it includes an operating table, on which a support mechanism and a grinding mechanism are arranged in sequence. The support mechanism includes two brackets. There is an active roller at the lower part of the bracket, and there are horizontally arranged driven rollers on the brackets on both sides above the active roller. There are a rotating motor and a reducer on the operating table between the two brackets. The output part of the rotating motor is connected to the input part of the reducer. The reducer has two output parts, and the two output parts of the reducer are respectively connected to the two active rollers through a connecting shaft. The grinding mechanism includes a guide rail. There is a slider on the guide rail, and there is a driving mechanism between the slider and the support table for driving the slider to slide along the guide rail. There is a grinding motor above the slider, and the grinding motor is fixed to the top of the slider through a support seat. A grinding wheel is concentrically fixed on the output shaft of the grinding motor. The operation process of using this grinder is simple and consumes less manpower.

[0004] The existing large-diameter steel pipe processing device has the disadvantage that it grinds the pipe end by driving the grinding wheel disc to rotate at high speed through a motor, and can only grind a single pipe, but cannot grind multiple pipes at the same time, resulting in low work efficiency. Therefore, we propose a square pipe end grinding device. Summary of the invention

[0008] Furthermore, the pressure plate is located inside the gantry, an anti-skid pad is glued to the bottom of the pressure plate, and auxiliary rods are connected to the two ends of the top of the pressure plate through threaded grooves, and the auxiliary rods run through the gantry; the provision of the anti-skid pad can play an anti-skid role.

[0009] Furthermore, an output shaft on one side of the driving motor is connected to the rotating shaft of the first rotating roller through a connecting sleeve.

[0010] Furthermore, two ends of one side of the auxiliary plate are connected with connecting rods through threaded grooves, one end of the connecting rod is fixed with a limiting block by bolts, and limiting slide grooves are opened at both ends inside the base plate, and the limiting block is located inside the limiting slide groove; the setting of the limiting block can prevent the connecting rod from falling off from the limiting slide groove.

[0011] Furthermore, rollers are equidistantly fixed to the bottom of the auxiliary plate by bolts.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Insert one or more ends of square tubes into the gantry, and push the square tubes so that their ends are against one side of the grinding belt. Open the cylinder to push the pressure plate downward to press the ends of the square tubes. The drive motor drives the grinding belt to rotate at high speed through the first rotating roller and the second rotating roller to grind one or more ends of the square tubes. Rollers are provided at the bottom of the auxiliary plate to make it movable, which is convenient for placing longer square tubes and prevents them from tilting easily.
