Abstract

The invention relates to a high speed cold rolling thread material head rolling collecting device. The high speed cold rolling thread material head rolling collecting device comprises a rack, a frontguiding tube and a rear guiding tube are respectively and fixedly connected with the front and the rear of the rack, the front guiding tube and the rear guiding tube are used for a thread material topass, one end of a special-shaped hinged plate is rotatably connected to the rack through a hinged shaft, the other end of the special-shaped hinged plate is connected with a rotating driving device of the special-shaped hinged plate, the special-shaped hinged plate is rotatably connected with a sensing plate through a torsion spring, a sensing switch is connected to the special-shaped hinged plate, the special-shaped hinged plate is further rotatably provided with a driven wheel, the rack is further rotatably provided with a driving wheel, a rotary barrel is mounted on the driving wheel in ahomocentric mode, the driving wheel is connected with a driving power device, the rack is fixedly connected with a cam plate, the end part, close to the driven wheel, of the cam plate is close to theinner side in the axial direction of the rotary barrel, and the end part, away from the driven wheel, of the cam plate is close to the outer side in the axial direction of the rotary barrel. Accordingto the high speed cold rolling thread material head rolling collecting device, waste materials formed in the initial stage of production line starting can be automatically collected.

Description

technical field [0001] The invention relates to high-speed cold-rolling equipment for wire rods, in particular to a collection device for unqualified wire rods when the high-speed cold-rolling line is just started, and belongs to the technical field of cold-rolling equipment. Background technique [0002] In the production of high-speed cold rolling of spiral wire rods, according to the production process of cold-rolled steel bars, the shearing device is installed behind the intermediate frequency heating furnace. After the production line is shut down, there will be some wire rods in the intermediate frequency furnace. The wire inside has cooled and hardened. With the pneumatic heating of the intermediate frequency furnace and the speed up of the wire rod along with the production line, the temperature of the first section of the steel bar is not up to standard and the wire rod produced in the first section of the production line is unqualified. The current way to deal with...

Problems solved by technology

With the pneumatic heating of the intermediate frequency furnace and the speed up of the wire rod along with the production line, the temperature of the first section of the steel bar is not up to standard and the wire rod produced in the first section of the production line is unqualified. The current way to deal with these unqualified wire rods in the first section is: after the intermediate frequency heating furnace, set The broken shears cut off the unqualified wires by one section and one section and collect them. When cutting, the broken shears cut the wires through two relatively rotating blades. Each cutting action will cause an impact on the wires. The impact will be transmitted to the corundum tube in the intermediate frequency furnace, causing damage to the corundum tube in the intermediate frequency furnace. After the damage, the production line will be shut down, affecting production efficiency. Moreover, the small sections of wire obtained in this way need to be collected and have no use value.
