Why should the coil of the Kaiping line be leveled with a leveling machine?

  • JIUZH 

In order to realize the automation of stamping production, it is necessary to use coiled sheets, and after the sheets are wound into coils, there will be longitudinal curl and transverse warping in the flatness, and there will also be residual internal stresses. If this kind of coil with problems in flatness and internal stress is directly uncoiled by the material frame and fed by the feeder and enters the processing machine for stamping, shearing and rolling forming, there will be a series of problems, so it is necessary to use a leveling machine for leveling processing.

  1. Problems of coils that have not been leveled by the leveler in stamping:

The presence of coil flatness defects and internal stresses can make it difficult to achieve precision forming and stamping on punch presses. On the one hand, it is difficult to guarantee the feeding accuracy of the feeder, there will be the phenomenon of sending more and sending less, which is easy to cause damage to the die, on the other hand, the existence of the problem of flatness and internal stress will make the quality and precision of the finished stamping processing product decline, and at the same time in the precision processing domain, if there is a defect in the flatness of the plate, it may also cause the entire punch automatic production line equipment to stop running, and the stability and efficiency of stamping processing are greatly reduced.

  1. Problems of coils that have not been leveled by the leveling machine in shearing processing:

When the material is fed by the feeder and enters the shearing machine for shearing processing, the internal stress in the plate will be completely released, and the material deformation will be visible to the naked eye, and the flatness defect of the coil will make the shearing accuracy not guaranteed. The flatness and accuracy of shearing and cutting are very important quality standards, because the finished product often needs to go through how many subsequent processes, and the accuracy and flatness cannot be guaranteed, which often leads to the scrapping of the finished product.

  1. Problems of coils that have not been leveled by the leveler in rolling forming:

In roll forming, rollers are used to change the shape of the metal coil through a series of processing operations. If there are defects in the material or if there is a problem with the flatness, it is difficult to achieve precise roll forming of the coil. Due to the fast rolling speed, the flatness defect of the coil will have a serious negative impact on the processing safety, stability and production efficiency of the roll forming line.

Jiuzhong intelligent R & D and production of the leveling machine is specially used for plate leveling and internal stress relief automation equipment, leveling machine from the inlet to the outlet, staggered arrangement of various groups of leveling rollers, a plate will have been continuously dislocated and pressed, through the elastic-plastic staggered bending and weakening deformation, the plate will become flat, more importantly, the stress is eliminated, to ensure that stamping, shearing, rolling forming can use the ideal processing materials.
