Heavy-duty material racks are advantageous because of their affordable price, wide application range (all kinds of stamping production lines and shearing lines can be used), and high degree of customization (volume inner diameter, outer diameter, and coil weight can be customized).

It has become the most used material discharging and unwinding equipment in the stamping industry.

At present, most of the stamping owners can see the heavy-duty material rack at the production site, but the heavy-duty material rack recognized by the stamping owner is a single type.

That is to say, the motor drives the spindle through the reducer to realize the unwinding, and the induction lever (large-scale induction frame) has different induction control.

Heavy-duty material racks are divided into two types: powered heavy-duty material racks and unpowered heavy-duty material racks. The actual stamping owners recognize that they are powered heavy-duty material racks.

Although the unpowered heavy-duty material frame is used less (mainly for stamping shelves, motors, and EI chips), it is still an indispensable part of the heavy-duty material rack category because it can greatly reduce the floor space of the production line.

When the leveling machine feed stops, the rotation should also stop, otherwise the coil material will be scattered due to release, which will affect the subsequent feeding.

However, usually after the feeding of the leveling machine is stopped, the trays will continue to rotate due to inertia, so the unpowered heavy material frame must be equipped with a rack brake device.

Since the feeding of the leveling machine is intermittent, that is, the feeding machine does not feed when it stops, and the feeding is performed after the bending is completed, the process is alternately performed at a high frequency, so that the frame brake device can also alternately perform high-speed braking. And loosen the tray.

However, conventional unpowered heavy-duty material frame brakes are unable to alternately perform high-speed braking and release of the tray.

When the powerless heavy material frame is used, the upper brake lever and the lower brake lever are driven to rotate along the brake bracket by the cylinder telescopic. When the cylinder is contracted, the upper friction plate and the lower friction plate clamp the brake disk, so that the brake disk stops immediately. Therefore, the tray is stopped from rotating, and the discharging is stopped quickly.

When the cylinder is extended, the upper friction plate and the lower friction plate loosen the brake disc of the material frame, and the brake disc rotates under the driving of the rotating sleeve of the tray, and the tray of the tray rotates freely with the rotating sleeve of the tray. Achieve automatic unwinding.

The new unpowered heavy-duty material frame can realize the functions of alternating high-speed braking and loosening of the supporting tile, which fundamentally meets the needs of customers for automatic stamping production.
