Guide trough for slitting and rolling rebar and restraint device installed on side plate for guide

Abstract

The invention provides a guide groove for screw-thread steel slitting and rolling. The guide groove comprises two side plates and a partition plate located between the two side plates, and a piece rolling channel is formed between the corresponding side plate and the partition plate; the guide groove further comprises a restraint device arranged on the side plates, and the restraint device comprises guide wheels and supporting arms; the guide wheels are rotatably arranged and located at outlets of the piece rolling channels, the axes are in the vertical direction, and the circumferential faces of the guide wheels protrude inwards the piece rolling channels and are at least flush with the inner surfaces of the side plates; the supporting arms are arranged at the outlets of the piece rolling channels, and the guide wheels are rotatably arranged on the supporting arms. The restraint device with an adjustable function is preferably provided, the restraint device is adjusted according to the filling degree of actual screw-thread steel cross ribs at a production scene, accordingly the ideal size and satiation degree of reinforced cross ribs are obtained, and the quality control level is stabilized.

Description

technical field [0001] The invention relates to a steel rolling equipment, in particular to a guide trough for slitting and rolling threaded steel, in particular to a finished front trough for slitting and rolling of larger-sized threaded steel and a guide trough set on the side plate for guide and guard restraint device. Background technique [0002] In the rebar production process, in order to improve the production efficiency of products (nominal diameter ≤ Φ22mm), split rolling technology has been widely used. In the existing technology, different split rolling processes are adopted according to the diameter of the product. For example, the specifications of four splits include Φ10mm~Φ12mm, the specifications of three splits include Φ14mm~Φ16mm, and the specifications of Φ18mm~Φ22mm adopt two split rolling manufacturing process. [0003] The slitting and rolling of larger-sized rebar generally adopts two slitting, that is, starting from the slitting pass rolling mill, ...

Problems solved by technology

However, this pass itself has almost no ability to automatically center the rolled piece during its operation, resulting in an asymmetrical shape of the rolled piece when it is rolled in the finished product's flat elliptical pass with convex bottom.
