Double ended coil reel for a quick coil change application

double-ended coil reel.JPG

Double ended coil reel, or say twin decoiler machine is an ideal choice for the sheet metal processing needs a quick coil change. When the one uncoiler spindle is working, the other one can set up with a new coil, which achieves a non-stop metal coil processing line.

This double-ended coil reel has heavy duty weld steel base for a stable structure. The spindle expansion is a hydraulic type, with loading capacity 3tons per side. Pneumatic hold-down arms on each side can prevent the metal strips springing back. Delta inverter achieves AC variable speed control, and a variable speed loop control helps a smooth strip feeding to straightener machine.

This double-ended coil reel can process metal coil width in 200mm, with uncoiling speed 16m/min. HongEr also offers double-ended coil reel in 60m/min uncoiling speed. Contact us for more details.

Uncoiler spindle is a critically important part of an uncoiler machine.

During the uncoiling operation, the contact position of the bearing with the spindle changes with the continuous rotation of the spindle. However, due to the influence of the weight of the sheet on the vertical downward force of the spindle, the reaction force of the bearing on the spindle can be used as a periodic alternating load.

When the spindle is subjected to a long-term cyclic alternating load, it will cause fatigue damage or even fracture at the load. Therefore, the uncoiler spindle with good bearing performance and fatigue resistance is very important in a sheet metal processing line.

According to the traditional design experience, increasing the size of the spindle can improve its bearing capacity and the fatigue phenomenon, but an excessive size tends to reduce the material usage rate and increase production cost. HongEr introduced a reasonable design method to determine the size of the uncoiler spindle several years ago, which can improve the performance of the spindle without wasting material.
