How To Make the Accuracy of The Uncoiling Line More Accurate?

Shearing machineis an important equipment on the uncoiling line, and the number of shearing strokes of the shearing machine largely determines the productivity of the uncoiling line. The shearing machine in the uncoiling line is generally speaking different from the ordinary shearing machine, which is due to the following special requirements for the shearing machine in the uncoiling line.

(1) High productivity. Plate thickness of 3mm open coil line, for the fixed length of 2000mm plate material, requires 30 to 35 sheets per minute shear, for the fixed length of less than 500mm plate material, requires 80 sheets per minute shear. Such high productivity is the general shear plate machine cannot meet.

(2) Full load. Many users of open coil line are 2 ~ 3 shift system, shear plate machine to shear 1 ~ 20,000 times a day. General-purpose shearing machine cannot be used at such a load.

(3) High reliability. Uncoiling line in the shear if the shutdown, it makes the whole uncoiling line downtime. Users such as automobile factories, an uncoiling line downtime will also cause several press line downtimes. Therefore, the requirement of the shear failure rate in the uncoiling line as low as possible, fault diagnosis and troubleshooting are relatively easy.



(4) The diversity of coil material. General shearing machine is to determine the shear force of ordinary carbon steel, and coil material in addition to the lower strength of galvanized class, tin, color coated plate, aluminum plate, but also high-strength stainless steel plate, weathering steel plate, pickling plate, etc. The coil materials used for car production are: uncoated cold-rolled sheet, hot-rolled pickled sheet, high-strength cold-rolled sheet, high-strength galvanized sheet, single- and double-sided electrolytic plating sheet, single- and double-sided hot-dip galvanized sheet, aluminum sheet, etc. Uncoiling line users often cannot mention the mechanical properties of the processed material, so in the design and selection of shearing machine, must consider the scope of application of the machine.

(5) Special shear mode. Some of the open coil line in order to stack the plate material not because of burrs and abrasion plate material surface, the requirements of the shear of the plate burr direction upward, therefore, the shear knife frame should be cut from the bottom up, this shear is called undercutting shear. Shear the plate material down to the movement of the conveyor belt, in order to avoid skewing, it requires the knife frame on the blade shape for the herringbone, which is particularly necessary for the short length of the fixed plate material.



In summary, the ordinary shearing machine cannot adapt to the requirements of the uncoiling line, must be designed for special shearing machine, KINGREAL Ltd. production shearing machine, its strength and stiffness reserves, energy reserves than ordinary shearing machine is much larger. Must break through the ordinary shearing machine of certain design concepts, in order to make the special shearing machine better meet the requirements of the uncoiling line.
