Abstract
The utility model relates to a universal mill edger pass designs into length for 15 ~ 50 mm's vertical line section with both ends about the edger roll shaft, and the part between two vertical line sections designs into the arc segment to the shaft concave yield, and the camber H of arc segment is 0.2 ~ 0.7 mm. Because the vertical roller of the universal rolling mill adopts the concave hole pattern design, the concave degree of the bottom of the high-speed steel rail is reduced, the external quality of the steel rail is improved, the high-speed rail with the speed of 350 kilometers per hour reaches the standard requirement, the product qualification rate of the high-speed rail and the stability of the production process are improved, the waste loss is greatly reduced, and the economic benefit is obvious. The method is suitable for the design and application of the vertical roller shape at the bottom of the high-speed steel rail rolled by the universal rolling mill.
Description
Technical field
The utility model belongs to the stress metal manufacture field, is specifically related to a kind of roll shape that is used for the universal mill edger roll of rolling high speed rail foot.
Background technology
Heavy rail is the special steel of railway construction, and heavy rail is divided into rail head, the web of the rail and the flange of rail three parts by the cross section.Because its section configuration complexity, in the operation of rolling dimensions control very difficult, problem such as have slightly that the rail height very easily appears in mistake, bottom width exceeds standard and asymmetric.Therefore, pass designs, calculation of parameter is complicated unusually, also require very strictness, and whether the pass parameter designing rationally will be directly connected to the dimensions of heavy rail and the precision of product.At present, the unit of universal mill adopts UR, E, UF three frames to arrange more, when producing hundred meters rail, because the temperature inequality causes the bottom of the finished product rail flange of rail recessed overproof serious, especially the high speed rail of 350 kilometers of speed per hours, though regulation bottom is recessed in 0.3mm in the standard, and the maximum recessed 0.5mm that reaches in the actual production, the high speed rail that causes universal mill to be difficult to produce to reach standard-required, thereby influence the qualification rate of high speed rail product, seriously restricting the production of high speed rail.
Summary of the invention
The purpose of this utility model just provides a kind of by changing universal mill edger roll body of roll shape, thereby produces the edger roll pass design that reaches recessed standard-required at the bottom of the high speed rail roller.
The technical solution of taking of the present utility model is:
A kind of universal mill edger roll pass is to change edger roll body of roll shape, is processed with pass on the straight barrel of edger roll, and the edger roll body of roll is designed to vertical line segment in two ends up and down, and the partial design between two vertical line segments becomes to the recessed arc of the body of roll.
The length of described vertical line segment is 15～50mm.
The camber H of the described arc i.e. height that is wired at the bottom of the arc of two vertical line segments is 0.2～0.7mm.
The employing the beneficial effects of the utility model are:
Because after the universal mill edger roll adopts recessed pass design, reduced the recessed degree of high speed rail flange of rail portion, improved the external mass of rail, make 350 kilometers high speed rails of speed per hour of production reach standard-required, the product percent of pass of high speed rail and the stability of production technology have been improved, greatly reduce loss due to spoiled work, had tangible economic benefit.
Description of drawings
Accompanying drawing is a universal mill edger roll pass schematic diagram.
Among the figure: 1 is edger roll, and 2 is vertical line segment, and 3 is arc.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As everyone knows, what the milling train edger roll of rolling heavy rail generally adopted is straight barrel, and promptly edger roll is a cylinder and do not have any pass.By accompanying drawing as seen, this novel universal mill edger roll 1 has changed the shape of the body of roll, is processed with pass on the straight barrel of edger roll 1.Its pass is shaped as: edger roll 1 body of roll is designed to vertical line segment in two ends up and down, and promptly edger roll 1 body of roll still leaves one section straight barrel in two ends up and down, makes edger roll 1 two ends respectively form a vertical line segment 2; Simultaneously the partial design between the two vertical line segments 2 is become to the recessed arc 3 of the body of roll.The concrete practice is: 1 barrel length 285mm is an example with edger roll, the vertical line segment 2 of 30mm is respectively reserved at two ends about edger roll 1 body of roll, the intermediate rest partial-length is 225mm, be end points with the remainder two ends then, to the inboard arc of drawing of edger roll 1 body of roll, and the camber that guarantees arc 3 promptly the height H that is wired at the bottom of the arc of two vertical line segments be 0.4mm, can make the universal mill edger roll pass of the utility model.
Claims (3)
1, a kind of universal mill edger roll pass is characterized in that, described edger roll body of roll two ends up and down is vertical line segment, is to the recessed arc of the body of roll between the two vertical line segments.
2, universal mill edger roll pass according to claim 1 is characterized in that, the length of described vertical line segment is 15～50mm.
3, universal mill edger roll pass according to claim 1 is characterized in that, the camber H of the described arc i.e. height that is wired at the bottom of the arc of two vertical line segments is 0.2～0.7mm.
