Abstract
The utility model discloses a round saw blade for cutting metals, which is used for hot sawing machines and cold sawing machines for sawing and cutting rolled pieces of rolling mills. The round saw blade for cutting metals is characterized in that the round saw blade for cutting metals is composed of a basal body 1 and an overlaying welding alloy layer 2 which is formed by manual electric arc overlaying welding and contacts with the rolled pieces; the thickness of the overlaying welding alloy layer is less than 3 mm. The overlaying welding alloy layer can form alloy overlaying welding saw teeth after sharpening. Compared with the existing integral saw blade, the saw blade can extend the service life of 1.5 times to 2 times.
Description
The utility model relates to a kind of metal circular saw of cutting, and particularly a kind of saw blade that has the hardfacing alloy layer, this saw blade are used for the rolled piece sawing to steel rolling mill of hot-metal sawing machine and cold sawing machine.
At present, state's inscribe metal circular saw is an overall structure, and general saw blade material is 65Mn, the red hardness of saw blade is lower when the sawing steel, and in sawing process, the cutting edge of saw blade is easy to wear, reface through saw blade several times, blade wear is to dimension limit, and whole saw blade is scrapped.
The purpose of this utility model provides a kind of metal circular saw of cutting of hardfacing alloy layer, improves the mechanical performance of saw blade cutting edge, can improve saw life during use.
The utility model is realized in the following manner.A kind of metal circular saw of cutting is characterized in that, on the saw bit matrix with cutting edge that rolled piece contacts on, it is hardfacing alloy layer below 3 millimeters or 3 millimeters that thickness is arranged.Saw bit matrix can be a carbon steel manufacturing, or uses the saw blade after the wearing and tearing.
The utility model can reduce the saw blade cost than existing whole saw blade, improves saw life, and manufacturing process is simple.
The drawing of accompanying drawing is described as follows:
Fig. 1 front view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A portion enlarged drawing of Fig. 1.
As Fig. 1, Fig. 2, shown in Figure 3, select a kind of carbon steel sheet, as the 45# steel plate through being processed into matrix 1, with cutting edge that rolled piece contacts on hardfacing alloy layer 2, this overlay cladding 2 forms through matrix 1 being given heat, hot built-up welding, postheating.This overlay cladding 2 can be used manual electric arc pile up welding, and welding rod adopts the high-speed steel welding rod, again cutting edge is carried out sharpening by certain size after the built-up welding.Elder generation sharpening tooth two rear flank, sharpening tooth front-back again.So just changed the single mechanical performance of original monometallic circle according to sheet.Make it at the cutting edge that contacts with steel, embody the higher red hardness that the hardfacing alloy layer is had.
This structure can also be used for the reparation of self, or to the reparation of single metal circular saw.Certainly for have major defect want first removal of defects after, repair again.
Claims (3)
1, a kind of metal circular saw of cutting is characterized in that on matrix (1), with hardfacing alloy layer (2) on the cutting edge that rolled piece contacts.
According to the described metal circular saw of cutting of claim 1, it is characterized in that 2, the thickness of said hardfacing alloy layer 2 is below 3 millimeters or 3 millimeters.
According to the described metal circular saw of cutting of claim 1, it is characterized in that 3, said matrix (1) is that carbon steel is made or uses the saw blade of wearing and tearing.
