Abstract
The utility model provides a variable frequency roller as the main component used by a transmission roll table. The utility model has the features of good abrasion tolerance and long life span, and comprises a bowl, the surface of which is provided vertically with evenly distributed incrustation slots along the outer radius, wherein incrustation strips arranged inside the incrustation slots are hard alloy strips. The utility model is of simple structure, easy fulfillment, and can effectively prolong the life span of the roller and decrease the changing times of the roller, as well as improve working efficiency.
Description
Technical field:
The utility model relates to technical field of ferrous metallurgy, and exactly it is that iron and steel enterprise produces major part---the Variable frequency roller on the steel rolling production-line transmission roller channels such as screw-thread steel, round steel, angle steel.
Background technology:
Domestic and international existing Variable frequency roller all adopts cast iron to make, because its use is frequent especially, general period of service surpasses all roll surfaces will be ground ditch by screw-thread steel, influences transmission,, must and change roller.Because the frequent Variable frequency roller of changing makes motor shaft loosening, greatly influences the service life of motor, also influences production efficiency in addition.China Patent No.: 96239406 disclose the utility model patent that a kind of name is called " a kind of Wearing-resistant roller ", and it is to add cover on roller, though can play the effect in certain prolongation roller life-span, cost is still higher.
Summary of the invention:
The purpose of this utility model provides a kind of Variable frequency roller, and it has wear-resistant, the characteristics of high life.It comprises roller, it is characterized in that: roller (1) surface vertically has uniform embedding groove (2) along external diameter, studs with Inlaid strip (3) in the embedding groove (2).Inlaid strip (3) is the hard alloy bar.
The utility model has the advantages that: because the surface of roller studs with Inlaid strip, greatly improved the abrasion test of roller, can reach service life more than 6 months, the service life of improving roller is more than 20 times, and can reduce production costs greatly, increases work efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the birds-eye view (part) of Fig. 1.
The specific embodiment:
Embodiment:
The utility model roller adopts the notes steel to make, handle back processing external form through actual effect, outside face at roller vertically mills the strip embedding groove, the hard alloy bar is bumped in the embedding groove, and it is uniform that embedding groove prolongs external diameter, and quantity can be arranged as required, after having inlayed Inlaid strip, grind Inlaid strip with circular grinder, make its size unified, do the kinetic balance check at last.During use, screw-thread steel contact be the hard alloy bar because the hard alloy bar has extremely strong hardness and resistance to abrasion, thereby roller can use the long period, prolonged the life-span of roller, reduces the number of times of roll change, reduced productive costs, improved work efficiency.
Claims (2)
1, Variable frequency roller, it comprises roller, it is characterized in that: roller (1) surface vertically has uniform embedding groove (2) along external diameter, studs with Inlaid strip (3) in the embedding groove (2).
2, Variable frequency roller according to claim 1 is characterized in that: Inlaid strip (3) is the hard alloy bar.
