This is basically the technique of cutting strips of numerous sizes from automotive metal parts manufacturer. The strips are used for making square rectangular and circular hollow sections or tubes. In this process, width in the strips range from 47/48 millimeters and thickness of 1. millimeters for creating 12 millimeters by 12 millimeters square hollow sections to width of 670 mm and thickness of 5.9 millimeters to 6. millimeters for creating 175 millimeters by 175 millimeters square hollow sections or 200 millimeters by 150 millimeters rectangular hollow sections. Just for this process, the hot rolled mild steel coil is bundled in a 6 to 10 tone-package by using a width of 1200 millimeters to 1300 millimeters.
Materials essential for the procedure are: slitting line machine, overhead crane, weighing scale, micro meter screw gauge, 3 meter steel tape along with the mild steel hot rolled coil.
Just before the process begins the coil is visually checked for deformities, that is certainly; burrs, dent edges, elongations, lamination and waviness. It ought to be checked for supplier tolerance on mechanical properties; thickness and width.
When the coil is okay, the straps which seal the high speed steel bar are welded off leaving one which could contain the coil preventing it from unfolding or uncoiling before loading it within the slitting line machine.
The coil is then placed into the slitting line machine with the help of an overhead crane and to the slitting line car with the slitting line bay. At this point the machine is turned on, the coil is pushed forward using hydraulic force and raised up to be sandwiched by cone-shaped mandrel of the plate drums that straightens them. The other scrap is scaled off utilizing a pinch roll-up, it is then utilized to secure the devxpky91 to penetrate through the rollers. Prior to the material reaching the cutters, the coil width is measured utilizing a 3 meter steel tape and the thickness measured using to 25 millimeters micro meter screw gauge to ensure they are of the required dimensions. These steps ought to be done thrice; at the outset of the process, when the material grows to the mid section so when it gets to the conclusion.
If all is okay, the appliance is turned back on as well as the material passed through the cutters. As being the process continues, the strips are transferred to the mandrel that straightens them, where the cold formed hollow section tube is used in order to avoid the strips from intermingling. The sides – which are section of the additional width – are considered extra material (scrap), these are rolled and attached by the scrap winder unit which moves inside a circular motion simultaneously with the machine as the material has been processed. Adjustment screws are fastened to lock the strips to ensure that because the mandrel begins to recoil, the strips would not detach or slip off.
