[0002] The grinding machine is a machine used to grind welded steel pipes. Steel pipes include seamless steel pipes and welded steel pipes. The cost of seamless steel pipes is higher than that of welded steel pipes. Generally, the welds of steel pipes need to be polished, and the surface of steel pipes is corroded with the air. Use The overall grinding process is required before the steel pipe is polished. At present, the steel pipe is generally polished with hand-held electric tools. This grinding method is inefficient, and the saf...

Abstract

The invention provides a steel pipe polishing device. The steel pipe polishing device is characterized in that two supporting plates are symmetrically hinged to each of the left side and the right side of the upper end of a base; every two supporting plates which are symmetrical along the central axis of the base form a V-shaped supporting structure; a roller is mounted on the inner side face of each supporting plate; the four supporting plates are each hinged to the base through a hydraulic cylinder; a polishing wheel mounted on the base is arranged in the symmetrical axis position of the V-shaped supporting structure located at one end of the base; and a belt wheel on a polishing wheel mounting shaft is connected with a belt wheel of an output shaft of a polishing motor through a transmission belt, and the polishing motor is mounted on the base. A polishing steel pipe can be firmly supported through the V-shaped supporting frames; the steel pipes of different pipe diameters can be polished through extending and retracting of piston rods of the hydraulic cylinders; and a lifting dust suction cover and a negative-pressure fan can suck iron scraps in the polishing process and meanwhile take the protection effect, so that using is safe and convenient, and the influence of polishing on the air quality is reduced.

Example Embodiment

[0022] Examples:
[0023] As attached figure 1 , 2 Shown
[0024] The invention provides a steel pipe grinding device, which is characterized in that it comprises a base 1, a roller 2, a grinding wheel 3, a transmission belt 4, a grinding motor 5, a hydraulic cylinder 6, a support plate 7, a steel pipe 8, a propelling roller 9, and a dust hood 10. , Screw 11, nut 12, handwheel 13, connecting hose 14, dust suction fan 15 and motor 16; the upper and left sides of the base 1 are respectively symmetrically hinged with two support plates 7, which are symmetrical along the central axis of the base 1. The supporting plates 7 form a V-shaped supporting structure. Each supporting plate 7 is equipped with a roller 2 on the inner side. The four supporting plates 7 are hinged to the base 1 via a hydraulic cylinder 6 respectively. The V-shaped supporting structure at one end of the base 1 There is a grinding wheel 3 installed on the base 1 at the axis of symmetry. The belt wheel on the mounting shaft of the grinding wheel 3 is connected to the belt wheel of the output shaft of the grinding motor 5 via the transmission belt 4. The grinding motor 5 is installed on the base 1, and the upper end of the base 1 is threaded A lead screw 11 is connected with a hand wheel 13 fixedly connected to the upper end of the lead screw 11, a push roller 9 is installed at the lower end of the lead screw 11, and the rotation shaft of the push roller 9 is connected to the output shaft of the motor 16. The nut 12 of 10, the suction hood 10 is connected to the suction end of the suction fan 15 arranged on the base 1 through the connecting hose 14, the steel pipe 8 is arranged on the four rollers 2 and the bottom is tangent to the outer contour of the grinding wheel 3. The two rollers 2 are tangent to the outer cylindrical surface of the steel pipe 8. The central axis of the V-shaped support structure formed by the two symmetrical support plates 7 coincides with the axis of the steel pipe 8. The nut 12 on the screw 11 can be adjusted between the dust hood 10 and the steel pipe 8. The advancing roller 9 is made of polyurethane material, and a number of transverse grinding ribs are uniformly distributed on the outer circumference of the advancing roller 9 and the advancing roller 9 is tangent to the outer circumference of the steel pipe 8.
[0025] working principle
[0026] When the present invention works, the piston rods of the hydraulic cylinder 6 on the two support plates 7 on one side of the base 1 are used to extend, the steel pipe 8 is placed on the roller 2 and the grinding wheel 3, and then the hydraulic cylinder 6 on the other side of the base 1 The extension of the piston rod enables the two V-shaped support structures to support the steel pipe 8. At this time, the rollers 2 on the four support plates 7 are tangent to the outer circumference of the steel pipe 8, and the grinding wheel 3 at the lower end of the steel pipe 8 is driven by the grinding motor 5. The outer circumference of the grinding wheel 3 can be polished at a high speed on the outer circumference of the steel pipe 8, and then the hand wheel 13 at the upper end of the screw 11 is rotated to make the polyurethane material propelling roller 9 at the lower end of the hand wheel 13 tangent to the outer circumference of the steel pipe 8, thereby grinding the edges Advance to realize automatic grinding, and the nut 12 at the upper end of the lead screw 11 can be adjusted to adjust the distance between the dust hood 10 at the lower end and the steel pipe 8. The dust hood 10 plays a protective role and can absorb flying during the grinding process. Dust, small iron filings, use negative pressure to fully absorb these impurities, protect the working environment, and are safe and reliable in use. The invention adopts a support plate and a base hinged to form two V-shaped support frames, which can firmly support the polished steel pipes and use hydraulic cylinders. The expansion and contraction of the piston rod can be used to polish steel pipes of different pipe diameters. The invention adopts a liftable dust hood and a negative pressure fan to absorb iron filings during the polishing process, and at the same time play a protective role. Safe and convenient, reducing the impact of polishing on air quality.
