Abstract
The utility model relates to a flat steel with arc-shaped grooves. The flat steel is a metallic material manufactured by adopting rolling technology. The flat steel is characterized in that one face of an ordinary long strip-shaped flat steel is provided with arc-shaped concave grooves which are periodically arranged according to definite dimension; the concave groove is applied to place dormant bolt heads in concrete products. Because the arc-shaped grooves and the flat steel body are simultaneously rolled into forming, the milling process of arc-shaped grooves in the products is relieved; the production technology of the product is simplified; not only the production efficiency is enhanced, but also the waste of metallic materials is decreased.
Description
The band steel of band deep-slotted chip breaker is by rolling one-time formed shape.
Strip band steel shape in railway construction, is particularly widely applied as the raw material of producing railway turnout base plate.Production technology when ordinary flat shape strip band steel is used for the production of switch bed plate is: by the dimensional requirement blanking---the auger shell keyhole---mills the bolt head arc groove---assembly welding auxiliary component.Milling Process arc groove complex process wherein, the time-consuming material that takes, it is higher to account for processing cost.
The purpose of this utility model is to utilize metal rolled technology one-shot forming, produce a kind of band steel, and then in producing the switch bed plate process, avoid bolt head groove Milling Process, simplify production technology with deep-slotted chip breaker, enhance productivity and the utilization rate of material, reduce production costs.
The technical scheme that realizes the utility model purpose is: produce a kind of band steel with deep-slotted chip breaker, it is provided with the arc groove that is periodic arrangement by certain size in the one side of strip band steel body.This arc groove is row along band steel body extension direction and is provided with, and therein on the heart line.Perhaps, be two row along band steel body extension direction and be provided with, and, be arranged in both sides with band steel body center line symmetry.Perhaps being three row along band steel body extension direction arranges; Wherein row are arranged on the center line, and other two row are arranged symmetrically in both sides with center line.
Accompanying drawing 1 is the front view with band steel of three row deep-slotted chip breakers;
Accompanying drawing 2 is Fig. 1 profiles along cross section, deep-slotted chip breaker place;
Accompanying drawing 3 is the front views with band steel of a row deep-slotted chip breaker;
Accompanying drawing 4 is the front views with band steel of two row deep-slotted chip breakers;
Accompanying drawing 5 is to use the main pseudosection of a kind of switch bed plate product of the utility model band steel production;
Accompanying drawing 6 is vertical views of Fig. 5.
Embodiment below in conjunction with accompanying drawing is further described the utility model: attached Fig. 1 and 2, accompanying drawing 3, accompanying drawing 4 have provided three kinds of embodiment of the present utility model respectively.What wherein attached Fig. 1 and 2 provided is the band steel with three row deep-slotted chip breakers, and it is that one side at strip band steel body 1 is periodic arrangement by certain size arc groove 2 is arranged, and its groove is three row along band steel body extension direction and arranges; Wherein row are arranged on the center line, and other two row are arranged symmetrically in both sides with center line.What accompanying drawing 2 provided is the band steel that a row deep-slotted chip breaker is set, and its arc groove 2 is along band steel body 1 extending directions therein on the heart line.What accompanying drawing 4 provided is the band steel with two row deep-slotted chip breakers, and its arc groove 2 is arranged symmetrically in both sides with band steel body 1 center line.Accompanying drawing 5 and accompanying drawing 6 have provided a kind of switch bed plate that the utility model is used for producing, arc groove 2 is below band steel body 1, and groove center has through hole, when using as switch bed plate, penetrate rectangular dormant bolt of band convex arc in the through hole, its bolt head crouches in arc groove 2.
During the utility model production punch can be set on request on roll, with the moulding simultaneously of band steel body and arc groove, produces simple and conveniently by rolling, in the specific product application, exempted the deep-slotted chip breaker Milling Process, both improve production efficiency, reduced the waste of metal material again.
