Detailed Description

The utility model is further described below with reference to the figures and examples.

As shown in fig. 1 and 2, the apparatus for grinding a rebar tip 2 according to the present invention comprises: turn round 2, connecting rod 1 and safety cover 4, this first terminal surface that turns round 2 is equipped with the first frosting 3 that is used for polishing the reinforcing bar end, the second end of turning round 2 and the first end threaded connection of this connecting rod 1, the second end and the rotating equipment of this connecting rod 1 are connected, this safety cover 4 and this first end threaded connection who turns round 2, and this safety cover internal surface is the second frosting.

When using, insert safety cover 4 with the reinforcing bar end, until supporting in first frosting 3, and fixed with the other end of reinforcing bar, open the rotary equipment, it is rotatory to make rotary equipment drive whole device, thereby make first frosting 3 polish the reinforcing bar end while the second frosting polishes the edge to the reinforcing bar, it is efficient to utilize the device to carry out the reinforcing bar and polish, do not need the manual work to carry out different portions of polishing and change between, the cost of labor has been reduced, and the reinforcing bar end after polishing is slick and sly.

Preferably, as shown in fig. 3, 4, 5 and 6, the first and second sanding surfaces 3 and 6 are at least one or a combination of abrasive grain surfaces, corrugated surfaces, spiral surfaces or radial surfaces, respectively.

The first frosting surface 3 and the second frosting surface are rough and have high hardness, and the first frosting surface 3 and the second frosting surface can be made into different forms according to the requirement. Should turn round 2 and have certain length, this safety cover 4 has certain thickness, when first frosting 3 and the wearing and tearing of second frosting to a certain extent, can unload and turn round 3 or safety cover 4 and change, and turn round 2 and safety cover 4 that unload down can deepen and continue to use behind the frosting line, practice thrift the cost.
