Structure Of Cold Rolled Ribbed Steel Bar Forming Machine

The cold-rolled ribbed steel bar production line is composed of a butt welding machine, a pay-off stand, a rust remover, a lubricating machine, a cold-rolled ribbed steel bar forming machine, a drawing machine, a stress relief mechanism, a take-up machine and an electrical operation control system. The type and number of equipment used in the production line process are different. At present, there are two main production processes for cold-rolled ribbed steel bars: pulley type and straight-forward type.
Pay-off frame: According to different needs, overhead, horizontal, and rotary uncoilers can be used, and the coil weight can reach 500~2000Kg. To ensure safety, a random line switch can be installed later.
Rust remover: In order to remove the oxide scale that is unfavorable to cold rolling, the repeated bending method of mechanical cleaning is generally used. There are linear types and space types, and the maximum wire diameter can reach φ20mm. The curved mechanical rust removal equipment has a simple structure, low cost and does not pollute the environment.
Lubricating machine: Use a worm feeder to continuously deliver lubricant to the material inlet and enter the drawing and rolling process. Most lubricants are hard calcium silicate - sodium type, soap powder plus molybdenum disulfide or emulsion can also be used.
Rolling equipment: The cold-rolled ribbed steel bar forming machine is the main equipment of the operation line. It has two types: active and passive. Active continuous rolling requires high investment and requires accurate pass grinding and adjustment, so it is generally not commonly used. The current trend is to use roller dies driven by wire drawing machines for passive rolling.
Drawing machine: The drawing machine is the power source of the work line. Single-cylinder and double-cylinder, horizontal and vertical drawing machines can be used. Generally, in order to extend its service life, the working surface of the drawing machine drum is coated with a special hardened layer.
Stress relief mechanism: In order to improve the elongation of the finished product and eliminate the surface stress of the finished product, a mechanism consisting of two sets of vertical and horizontal stress rollers is generally used. By repeatedly bending the finished product, the elongation is increased by 1% to 2%. It also has the following features: Straightening effect.
Wire take-up machine: According to the user's product specifications and roll weight, direct take-up type, elephant trunk type, and I-wheel type take-up machines can be selected. It can also be directly straightened and cut to length to produce straight strips.
