Abstract
The utility model relates to dovetail groove type shaped steel, which belongs to the fields of metal rolling and cold-drawing molding. The dovetail groove type shaped steel comprises a steel body, wherein the steel body is provided with an open slot, the four angles of the steel body are all right angles, the end surface wall thickness of inwards bent anchor hooks at both sides of the open slot is 12+/-2mm, and the inwards bent angle of the inwards bent anchor hook is 65+/-4 degrees. Because the end surface wall thickness of the inwards bent anchor hooks at both sides of the open slot is increased, and the inwards bent angle is 65 degrees, the tensile strength of a product is increased, the structures of the inwards bent angles are reasonable, the production cost is low, the surface precision is high, the product is more widely used, the specification size of the product can be set as required, and the product is mainly used for other fields of glass curtain wall hanging, railway tunnels and underground equipment suspension and the like. The utility model uses a steel plate as a raw material for lowering the production cost, adopts semi-continuous rolling and cold-drawing molding processes for production, improves the precision of the product and has greater market competition and complete product specifications.
Description
Technical field
The utility model relates to a kind of dovetail groove type shaped steel, belongs to metal rolled cold drawing forming field.
Background technique
1, " the hot rolling hot bending C shaped steel " of domestic existing manufacturer production all makes raw material with steel billet at present, develop rapidly along with China's Iron And Steel Industry, make the iron and steel production capacity all to large scale development, therefore on market, be difficult to purchase little shaped blooms at present, if need the secondary split rolling method to become a useful person with big specification steel billet production, improved cost of goods manufactured so greatly.
2, the small-sized continuous casting billet that has on the market can not guarantee the quality of continuous casting billet to make the product surface quality that shuts out bad, and defectives such as longitudinal crack, slag inclusion are arranged.
3, the C shaped steel of producing with hot rolling, hot bending, its surface size precision is not high, tolerance dimension control is bad, product tensile strength is low, is difficult to squeeze into the international market.
4, to only limit to the ratio of its wide length be 1: 2 ± 0.125 for hot rolling hot bending C shaped steel, specification, limited the scope of promoting the use of of this series products like this.
5, C shaped steel product specification is single, and the interior curved grasp end face wall thickness of opening slot both sides and inside corners design are unreasonable, and tensile strength is low.
Summary of the invention
The purpose of this utility model is the tensile strength that can improve product is provided, and reduces production costs, saves energy and reduce the cost the dovetail groove type shaped steel that product variety is complete.
Technical solution: comprise the steel body, the steel body is provided with opening slot, and the interior curved grasp end face wall thickness of opening slot both sides is 12mm ± 2mm, and the inside corners angle of interior curved grasp is 65 ° ± 4 °.
The purpose that reduce production costs of the utility model in order to reach, the steel body is made raw material with steel plate, adopts semicontinuous rolling, cold drawing moulding process to produce, and has improved the precision of product than existing explained hereafter, makes product appearance more good-looking, and the market competitiveness is more arranged.
The utility model is owing to the interior curved grasp end face wall thickness with the opening slot both sides increases to 12mm by C shaped steel 8mm, the inside corners angle is 65 °, the tensile strength of product is increased, the structure of inside corners is more reasonable, cost of production is low, surface accuracy is high, it is more extensive to use, the specification of product can be set as required, is mainly used in dress extension, the railway tunnel of glass curtain wall, the extension of subway equipment and other field such as hangs.
The utility model technology has overcome the defective that can only produce single variety in original technology.Country advocates autonomous innovation energetically now, improve the localization rate of parts and components of various products, can save a large amount of foreign exchanges for country, and product is got to the international market.Can produce German state-of-the-art embedded part by present technique, product price can be sold several times of domestic production embedded part up till now.

Embodiment
Embodiment
With reference to accompanying drawing 1, the utility model steel body 1 is made raw material with steel plate, adopts semicontinuous rolling, cold drawing moulding.1 four angles of steel body are the right angle, cross section be have outer little in the rectangle of big opening slot, the wide of its cross section is 34 ± 1mm, length is 52 ± 1mm, thick is 4 ± 0.5mm, and the end face wall thickness of interior curved grasp 2 is 12 ± 2mm, and interior curved 3 the angle of interior curved grasp is 65 ° ± 4 °.
50 * 25C shaped steel of the utility model and prior art is made comparisons: its surface accuracy height, see that from the cross section pulling capacity (tensile strength) between interior curved grasp 2 and the T type bolt is higher than 50 * 25C shaped steel far away.
Claims (2)
1. dovetail groove type shaped steel comprises the steel body, and the steel body is provided with opening slot, it is characterized in that, the interior curved grasp end face wall thickness of opening slot both sides is 12mm ± 2mm, and the inside corners degree of interior curved grasp is 65 ° ± 4 °.
2. dovetail groove type shaped steel according to claim 1 is characterized in that the steel body is made raw material with steel plate, adopts semicontinuous rolling, cold drawing moulding.
