Abstract

The utility model relates to a hard alloy inner hole burring reamer, which is composed of a reamer head 1 and a reamer handle 2. The utility model is characterized in that four equant cross-shaped cutting edges 3 are arranged on the reamer head 1; hard alloy reamer blades 1.1 are welded on the cutting edges 3; weld layers 1.2 are arranged between the hard alloy reamer blades 1.1 and the cutting edges 3. The hardness of high speed tool steel (rapid steel) is only about HRC 60 DEG, while the hardness of the hard alloy reamer blades is more than HRC 80 DEG. Therefore, when cutting or milling metal by the utility model with so high hardness, the utility model is naturally sharp and difficult to wear. The utility model has the advantage of rapidness, and the work efficiency can be increased by 35% to 40%. The work efficiency is increased, and the cost is reduced.

Description

Carbide alloy endoporus burring reamer

Technical field

The utility model product belongs to a kind of metal machining tool, particularly a kind of carbide alloy endoporus burring reamer.

Technical background

In the boiler processing industry, when machining hole, because hole depth or boiler can't advance the people, burr is difficult to remove.And the special-purpose reamer that uses now is a kind of monoblock type high-speed tool steel (high-speed steel) making, and the price comparison of high-speed steel is expensive, if whole cutter hub is all made of high-speed tool steel, not only involve great expense, and efficient is not high, because the hardness of high-speed tool steel only is about HRC 60 degree, uses soon that cutting edge is is just worn and torn, thereby cause very big waste.

Summary of the invention

The purpose of this utility model is to disclose a kind of, cutting edge hardness height, use cost is cheaper, operating efficiency is more remarkable, and save trouble, labour-saving carbide alloy endoporus burring reamer.

For reaching the technical scheme that above-mentioned purpose adopts be:

Carbide alloy endoporus burring reamer is made of reamer head 1 and reamer handle 2 two parts, it is characterized in that on reamer head 1, has four to be divided into criss-cross cutting edge 3; On cutting edge 3, be welded with carbide chip 1.1, between carbide chip 1.1 and cutting edge 3, weld layer 1.2 is arranged.As shown in Figure 1, 2.

Advantage of the present utility model is:

1, because the hardness of high-speed tool steel (high-speed steel) only be about HRC 60 degree, and the hardness of carbide chip is more than the HRC80 degree, and so high hardness is when cutting or Milling cut metal, and is sharp naturally and be difficult for loss, and is quick and the raising work efficiency reaches 35-40%.

2, carbide alloy endoporus burring reamer, be difficult for loss owing to sharp, naturally just has long-lived quality, particularly whole Milling head needn't use high-speed tool steel (high-speed steel) material to make entirely, only get final product with a small pieces carbide alloy, not only work efficiency improves greatly, and cost also reduces greatly.
