Abstract

A device of the present invention that can simultaneously polish the inner and outer burrs of the pipe mouth of the steel pipe is mainly used for grinding the pipe mouth of the steel pipe and removing the pipe mouth burrs. It has a simple structure and can simultaneously polish the inner and outer burrs of the pipe mouth of the steel pipe; Disc, arc-shaped grinding blocks, spokes, and shafts; its main working principle and installation method are: first, according to the diameter of the steel pipe, find the scale line of the corresponding diameter on the disc, and place the V-shaped grooves of the four arc-shaped grinding blocks. Align the center line with the scale line, then install and fix four arc-shaped grinding blocks, then align the center line of the V-shaped grooves of the four arc-shaped grinding blocks with the nozzle of the steel pipe, start the driving device of the rotating shaft to rotate the rotating shaft, and the rotating shaft drives The disc and four arc-shaped grinding blocks rotate, and the two V-shaped sides of the V-shaped grooves of the four arc-shaped grinding blocks simultaneously grind the inner and outer burrs of the steel pipe nozzle.

Description

A device that can simultaneously polish the inner and outer burrs of the pipe mouth

technical field

The invention is mainly used for grinding the nozzle of the steel pipe and removing the burr of the nozzle.

Background technique

At present, the nozzle grinding patents of relevant steel pipes that have been applied for or authorized have complex structures, and cannot simultaneously polish the inner and outer burrs of the nozzle of the steel pipe.

Contents of the invention

The present invention overcomes the above-mentioned defects. It has a simple structure and can simultaneously polish the inner and outer burrs of the pipe mouth; the present invention is mainly composed of a disc (1), an arc-shaped grinding block (2), a spoke (3), and a rotating shaft (4) ; The rotating shaft (4) is fixed at the center point of the disc (1), and the four spokes (3) are fixed on the disc (1) symmetrically, and the scale (8) is engraved on the disc (1), and the arc is polished The front end of the block (2) has a V-shaped groove (6), and the longitudinal direction of the V-shaped groove (6) is arc-shaped, and the rear end of the arc-shaped grinding block (2) has a slot (7), and the slot (7) is locked It can be fixed firmly on the spokes (3) of the disc (1); the main working principle and installation method of the present invention are: first, find the scale line of the corresponding diameter on the disc (1) according to the diameter of the steel pipe (5) , align the center lines of the V-shaped grooves (6) of the four arc-shaped grinding blocks (2) with the scale line, then install and fix the four arc-shaped grinding blocks (2), and then place the four arc-shaped grinding blocks (2) Align the center line of the V-shaped groove (6) with the nozzle of the steel pipe (5), start the driving device of the rotating shaft (4) to rotate the rotating shaft (4), and the rotating shaft (4) drives the disc (1) and the four arcs The grinding block (2) rotates, and the two V-shaped edges of the V-shaped grooves (6) of the four arc-shaped grinding blocks (2) simultaneously grind the inner and outer burrs of the steel pipe (5) nozzle.
