Abstract

Disclosed is a high-speed steel roller for making glass, which is composed of a common steel roller body and high-speed steel furring slats. The utility model is fabricated through the processes of lathe pressing and quenching after a layer of high-speed steel slats with a certain thickness is spliced and welded on the surface of a common steel roller. The utility model can be normally used under the temperature condition from 900 to 1000 DEG C and has the characteristics of long service life and high flatness of glass products, and the pressed plate glass is hard to partially deform.

Description

High-speed steel roller for glass making

The utility model relates to nonmetal processing facility technical field, is applicable to the roll facility that production sheet glass or figured plate glass are used.

Existing produce the roll that sheet glass or figured plate glass use, generally make cylinder, intermediate sleeve by No. 45 steel or bearing steel, there is the passage of logical water coolant to constitute in the middle of spindle nose and the roll, such roll is used for glass production, can be with the glass metal of temperature at 800～900 ℃ molten molten state, make sheet glass through spreading repeatedly, use aborning at present, it is poor to exist red hardness, and work-ing life is short, the glassy product that Rolling Production is come out, roughness is big, has seriously influenced the quality of glass production.

The high-speed steel roll that the glass production that it is good that the purpose of this utility model provides a kind of red hardness is used, use this roll to be difficult for producing local deformaton, can improve roll work-ing life more than three times, and the sheet glass product of producing, the high effect of planeness had.

The design of the high-speed steel roll that the utility model glass production is used is to realize (Fig. 1) like this, by No. 45 steel or bearing steel is made common roll body and high-speed steel veneer bar constitutes, wherein ordinary steel roll body is by cylinder (3), intermediate sleeve (4), spindle nose (1) constitutes, and cooling-water duct is still arranged in the middle of the roll.High-speed steel veneer bar is to cut with certain thickness high-speed steel plate to make the certain lath of width, length is identical with various roller surfaces, form ， And welding on the surface of ordinary steel roll body cylinder (Fig. 2) with the plate bending rolls compacting, carry out car system, quenching formation high-speed steel roll again.

Effect of the present utility model is on the surface of the common roll that No. 45 steel of existing usefulness or bearing steel are processed into, welded the good high-speed steel strip material of the certain thickness red hardness of one deck, the high-speed steel roll of processing and manufacturing like this, can under 900～1000 ℃ temperature condition, normally use, the sheet glass of compacting is difficult for producing local deformaton, the product planeness height of producing is used in the production, and can improve effect three times or more than ordinary steel roll its work-ing life.

Fig. 1 is the structure iron of the high-speed steel roll used of glass production.

Fig. 2 is the outside view of Fig. 1.

Fig. 3 is welding veneer high-speed steel panel construction figure.

The embodiment of the high-speed steel roll that the utility model glass production is used is the cylinder by ordinary steel roll body, intermediate sleeve, and spindle nose constitutes, and cooling-water duct is arranged in the middle of the roll.High-speed steel veneer bar is cut into the lath of wide 60～80mm with the thick plate of 3mm, length is identical with various ordinary steel roller surfaces, form and the radian lath (Fig. 3) that dwindles the ordinary steel roll body surface basically identical of 3mm with the plate bending rolls compacting, weld on ordinary steel roll body cylinder surface (Fig. 2) with CHR322 or CHR327 welding rod, in accordance with regulations size car system processing on lathe again, make surperficial quench treatment, reaching hardness is 55～57 degree, carries out precision work then and form high-speed steel roll facility on lathe.

Claims

1, the high-speed steel roll used of a kind of glass production, by the cylinder that No. 45 steel or bearing steel are made, intermediate sleeve, spindle nose is formed, and it is characterized in that welding has the certain thickness high-speed steel lath of one deck on the surface of cylinder.

2, high-speed steel roll according to claim 1 is characterized in that the thickness of the high-speed steel veneer lath that welds is 3mm, and width is 60～80mm, and length is identical with the length of various ordinary steel rolls.
