A method of drawing steel

Abstract

The invention discloses a steel pulling method. The steel pulling method is characterized in that a steel pulling trolley with a purely mechanical steel pulling mechanism is arranged on guide rails of the steel pulling trolley; the mechanical steel pulling mechanism comprises a hooking and taking parts, a sliding block and a sliding plate, the hooking and taking parts are rotatably installed on a rotating shaft, all the hooking and taking parts are in a triangular shape, the sliding block is located at one end of a front steel pulling row, and the sliding plate is arranged in the gap between the hooking and taking parts. According to the steel pulling method, mechanized steel pulling can be achieved, shutdown due to an electrical failure is avoided, steel pulling fluency is better, production efficiency is high, and meanwhile the method has the advantages that profile steel can be precisely stopped at input roller ways, so that steel pulling is facilitated.

Description

technical field [0001] The invention relates to a steel drawing method used on a steel inspection table in a steel production line. Background technique [0002] Sectional steel refers to bar-shaped steel with a certain cross-sectional shape and size. During the production of section steel, after rolling and forming, it needs to go through hot sawing, cooling in a cold bed, straightening by a straightening machine, cold sawing and other processes. The inspection table is located on the assembly line behind the cold sawing machine, and is used to inspect the section steel to see if it meets the standard, and to paste the qualified label. [0003] A profiled steel inspection platform currently used by the applicant includes an input roller table composed of several input rollers arranged side by side and horizontally arranged at intervals, an output roller table composed of several output rollers arranged side by side and horizontally arranged at intervals, the input roller ta...

AI Technical Summary

Problems solved by technology

This electrical control method has the defects of complex structure of electrical components, high cost and easy occurrence of electrical faults, which leads to shutdown and maintenance and reduces production efficiency; Sliding friction, so there are still serious wear and tear with the pull steel guide rail, and the wire rope and the pull rod trolley are connected by winding to form a rope end, which is inconvenient to connect and poor in reliability.

In addition, in the existing steel drawing technology, when the section steel moves forward on the input roller table, it is difficult to accurately control it to stop before it needs to enter the inspection platform, and there is a defect that the positioning of the section steel on the input roller table is inconvenient to control.
