Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, a pipe cutting blade for a pipe cutting machine comprises a base disc 1, a shaft hole 2 is formed in a central shaft of the base disc 1, the shaft hole 2 is used for fixedly mounting the base disc 1 on a rotary driving output shaft of the pipe cutting machine, a cutting head 3 is arranged on the outer peripheral side of the base disc 1, the cutting head 3 and the base disc 1 are sleeved in an embedding mode of a convex block and a groove and are sealed and glued by using an adhesive, the edge of the cutting head 3 is opened, polishing sheets 4 are circumferentially arranged on two sides of the cutting head 3, the polishing sheets 4, the cutting head 3 and the base disc 1 are glued by using the adhesive, wherein in order to improve the bonding firmness, when the cutting head 3 is sleeved in the embedding mode of the base disc 1, platforms on two sides of the base disc 1 need to be exposed, the polishing sheets 4 are also provided with convex platforms matched with the exposed platforms on the base disc 1, the arrangement is used for resisting the reaction force of the base disc 1, the firmness is guaranteed.

From this, when the basal disc 1 rotates at a high speed and advances to waiting to process tubular product, cut the tubular product by cutting tool bit 3, the piece of polishing 4 then stretches into the cutting cut that exposes after the cutting in, polishes tubular product cutting section, will cut and polish integrative going on, need not to do more frock processes again, improve tubular product machining efficiency.

Wherein the grinding plate 4 is composed of an inclined grinding plate 41 and a flat grinding plate 42, one side of the inclined grinding plate 41 is bonded to one side of the cutting head 3, the bottom part of the inclined grinding plate 41 is bonded to the raised platform of the base plate 1, one side of the flat grinding plate 42 is bonded to the side of the base plate 1, and the inclined grinding plate 41 and the flat grinding plate 42 are integrally formed. With the arrangement, the reaction force applied to the polishing sheet 4 in the feeding process can be borne on the base disc 1, and the firmness and the stability are ensured.

Wherein, the free side of the inclined grinding sheet 41 is set as an inclined side surface, the free side of the flat grinding sheet 42 is a plane, and one edge of the inclined side surface is transitionally connected with the edge of the cutting head 3, and the other edge is connected with the side plane of the flat grinding sheet 42. In the stage of polishing after carrying out the cutting, polish the section of tubular product for the inclined plane by the oblique side of oblique abrasive disc 41 earlier, continue the feed again, can polish the inclined plane for the plane again, make whole polishing in-process, not only can be by cutting tool bit 3 steady transition to the stage of polishing, still can be in whole stage of polishing, oblique abrasive disc 41 and plain abrasive disc 42 are little with tubular product fracture surface area of contact, not only be favorable to steadily polishing and guarantee the smoothness nature, still reduce the resistance of polishing piece 4, guarantee polishing piece 4's life.

The inclined plane of the inclined grinding sheet 41 can also realize the following functions: only by the feed of cutting tool bit 3, drive oblique abrasive disc 41 and polish the fracture of tubular product for the inclined plane, flat abrasive disc 42 does not contact with the tubular product fracture to, when tubular product butt joint, two fractures make up and are a groove, are convenient for carry out groove welding.

Wherein, carry out the fillet with being connected of oblique abrasive disc 41 and flat abrasive disc 42 from the right side to the smooth transition of oblique abrasive disc 41 to flat abrasive disc 42 section prevents to appear the dent because of connecting the tubular product section that the abrupt change leads to.
