Abstract

The utility model provides a pattern roller used for reducing the deformity and the crack of a roller when a metal pattern plate is rolled. The upper edge of a pattern groove of the pattern roller is formed by connecting arc lines or by close connecting arc lines and straight lines in a smooth transition mode. The junction of the upper edge of the pattern groove and the roll surface are processed into a smooth transition curvilinear shape. Hence, the upper edge of the pattern groove has no zigzag processing closed angle, and the utility model can furthest reduce the conditions, such as crack, deformity, etc. of the pattern roller caused by stress concentration in the production of rolling plates, and can extend the service life of the pattern roller.

Description

Flower groove upper edge is the riffled roll of lenticular shaped smoothed curve

The utility model relates to a kind of riffled roll that rolling cross section is the special shape sheet metal that is used for.

At present, the riffled roll of lenticular shaped decorative pattern sheet metal Rolling Production producer use both at home and abroad, its roll body surface, promptly the embossed channel that is used for the roll compacting decorative pattern of being processed on the roll surface promptly spends the trough rim upper edge of groove to have broken line shape " processing wedge angle ".Force analysis shows, this is in and rolls in the plate production process normal stress and concentrate the part of causing the roll crackle even making roll body to become chunky shape to come off, and is commonly called as roll and " loses flesh ", causes roll integral body to be scrapped, limited the service life of riffled roll, made metal pattern sheet material production cost high.

The purpose of this utility model is to provide a kind of colored trough rim upper edge not have " processing wedge angle " and is the riffled roll of lenticular shaped smoothed curve, to improve its service life.

For achieving the above object, designer of the present utility model has proposed following technical proposals and has required to be protected.What this technical scheme adopted is a kind of " flower groove upper edge is the riffled roll of lenticular shaped smoothed curve ", be processed with recessed on this roll roll surface by trough rim, the formed colored groove of bottom land, it is characterized in that the trough rim upper edge is that camber line or camber line and straight line seamlessly transit the shaped form that sealing is formed by connecting, trough rim lower edge and bottom land junction are the arc that seamlessly transits.

Spending the groove upper edge as mentioned above is the riffled roll of lenticular shaped smoothed curve, it is characterized in that, the junction of flower groove upper edge and roll surface can be the shaped form that seamlessly transits.

Because riffled roll described in the utility model, the trough rim upper edge of its flower groove is the closed curve shape that seamlessly transits, eliminated the processing wedge angle that exists in the prior art herein, therefore, can reduce in rolling the plate production process stress herein to greatest extent concentrates and causes " lose flesh " generation of situation of roll body crackle, can improve riffled roll service life, reduce metal pattern sheet material production cost.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is roll roll body shape and colored groove shape that roll surface processed and a schematic diagram of spending groove to distribute among the utility model embodiment 1.

Fig. 2 is the expansion schematic diagram that the flower groove distributes among the utility model embodiment 4.

Fig. 3 is the generalized section of flower groove among the embodiment 1.

Fig. 4 is shape and the expansion schematic diagram that flower groove 3 distributes and the generalized section of spending groove 3 of flower groove 3 among the embodiment 2.

Fig. 5 is the generalized section of flower groove 3 among the embodiment 3.

Fig. 6 is the generalized section of flower groove 3 among the embodiment 4.

Embodiment 1 is based on the shape and the flower groove distribution form of lenticular shaped riffled roll in the prior art, its flower groove shape is improved, and makes it possess the utility model technical characterictic.In embodiment 1, as shown in Figure 1, the shape of roll body 1 is identical with lenticular shaped riffled roll roll body shape in the prior art, difference is among the utility model embodiment 1 as shown in Figure 2 between the two, spend the ellipse that is shaped as of groove 3, the trough rim 4 of sealing is that level and smooth arc connects, and does not have " the processing wedge angle " of broken line shape, as shown in Figure 3, its bottom land 5 and junction, trough rim 4 lower edge also arc for seamlessly transitting.

In embodiment 2, the shape of riffled roll roll body 1 and the flower groove 3 distribution form all with embodiment 1 in identical, difference from Example 1 as shown in Figure 4, can there be one section straight line portion that is connected with its horizontal trough rim 4 level and smooth arcs in oval-shaped two longitudinal axis ends, its trough rim 4 upper edges, and the lower edge of its trough rim 4 and bottom land 5 junctions are the arc that seamlessly transits.

As Fig. 5, shown in Figure 6, embodiment 3 and embodiment 1 and embodiment 4 compare difference and only are that the upper edge of colored groove 3 of embodiment 3 and embodiment 4 and the junction of roll surface 2 are the shaped form that seamlessly transits with embodiment 2.

Designer of the present utility model once utilized embodiment 1 and embodiment 2 described two kinds of riffled rolls respectively, single respectively roller experiment rolling meets 4210 tons and 3560 tons of the checkered steel plates of " GB/T3277-91 " national Specification in hot continuous rolling factory of Benxi Iron and Steel (Group) Co., Ltd. homemade " 1700 millimeters hot strip continuous-rolling machines ", and once utilized embodiment 3 and embodiment 4 described riffled rolls testing with overlapping the production of carrying out single rolling system checkered steel plate more in enormous quantities on the milling train respectively, its result proves, the above-mentioned various riffled roll that possesses the utility model technical characterictic all can reduce " lose flesh " generation of situation of riffled roll crackle effectively in rolling plate production, the minimum raising 1.5 to 2 times of riffled roll service lifes obviously reduces the checkered steel plate production cost.

Claims

1, a kind of groove upper edge of spending is the riffled roll of lenticular shaped smoothed curve, be processed with recessed on this roll roll surface by trough rim, the formed colored groove of bottom land, it is characterized in that the trough rim upper edge is that camber line or camber line and straight line seamlessly transit the shaped form that sealing is formed by connecting, trough rim lower edge and bottom land junction are the arc that seamlessly transits.

2, riffled roll as claimed in claim 1 is characterized in that, the upper edge of trough rim and the junction of roll surface can be the shaped form that seamlessly transits.
