Abstract
The utility model belongs to a cutting-tool, and in particular relates to a brazing alloy rust scraper. The prior traditional rust scrapers are made of carbon steel blades which are easy to get heated, dull and easy to slip. When in operation, the blades is needed to be replaced, which is time-and-labor-cost while with a bad rust removing effect. The utility model aims at overcoming the shortages and has a dual-homalocephalus and duplex ally, which is made after striking and forging the two ends of the round steel into the flat head and welding the two alloy blades at the ends of the two flat heads together with copper. The utility model has the advantages of rational structure, convenient carrying, time and labor saving and excellent rust removing effect.
Description
Technical field:
The utility model belongs to cutting tool, is specifically related to a kind of brazing alloy derust knife of using.
Background technology:
As everyone knows, the staff in China work area of vast road and bridge, need constantly the rail support of railway steel bridge and beam are in length and breadth eliminated rust, paint, and existing derust entirely, paint after totally by manually derusting, the instrument that is relied on that derusts is to adopt the conventional carbon steel blade, and these blades are to make through forging " quenching ", need carry 3-5 piece cutting tip during operation on bridge, and friction is used back and forth, because heating annealing, not sharp and generation is skidded, and by the tool changing sheet, blade changes most work also to be difficult to finish entirely in operation, the poor effect of derusting, not only time-consuming, strengthen labourer's labour intensity, and influence operation work efficiency and quality.
Summary of the invention:
The purpose of this utility model is according to above-mentioned weak point, and provide a kind of brazing alloy derust knife, this blade is to adopt alloy blade, when each bridge worker goes to work, only need carry two brazing alloy derust knifes, it is sharp, can improve work efficiency more than 5 times, it is not only time saving and energy saving, and is durable in use, reduce labor intensity, and the effect of derusting is good.
The utility model is to realize like this.This product is the two alloy knifes of two homalocephalus, and round steel is the flat shape through forging two beaten, and with oxygen and acetylene brazing two alloy blades employing brazings is connected homalocephalus place, round steel two ends then.
Description of drawings:
Fig. 1 is the utility model overall structure front view.
Fig. 2 is the utility model overall structure side view.
Drawing reference numeral:
1 left alloy blade 2 left homalocephalus 3 round steel
4 right homalocephalus 5 right alloy blade 6 brazing junction
The specific embodiment:
Brazing alloy derust knife of the present utility model is the two alloy knifes of two homalocephalus, and the two that is about to round steel (3) is flat head (2) (4) through forging, and with brazing (6) two alloy blades (1) (5) is welded the two alloy knifes of the two homalocephalus of binding formation at two homalocephalus end places.
This Derust knife of copper welding alloy is reasonable in design, and is simple in structure, portably uses conveniently cutter The knife edge profit can improve the work work efficiency greatly, reduces labour intensity, and it is effective to derust.
Claims (1)
1, a kind of brazing alloy derust knife, it is characterized in that this alloy knife is two homalocephalus, i.e. two ends setting at round steel (3) is flat head (2) (4), and with brazing (6) two alloy blades (1) (5) is welded the two alloy knifes of the two homalocephalus of binding formation at two homalocephalus end places.
