Heavy-duty material racks are currently used in the stamping industry. They are widely used in various fields of stamping and manufacturing. When it comes to it, stamping owners are not unfamiliar, but the customers are talking about, familiar with and contact with them. They are all powered and heavy-duty material racks with vertical electric control boxes. It is actually only one of the heavy-duty material racks. There is another kind of powerlessness that needs to be pulled by the subsequent press line machine. The brake device is used to control the unpowered heavy-duty material frame with the elastic material unwinding. The unpowered heavy-duty material frame is used less in the traditional stamping processing field, but it is needed in special processing fields such as stamping shelves and motor EI films. The small area of the waiting area can save the space and other advantages and there is no small market share.
Performance characteristics of unpowered heavy-duty material rack: The non-moving heavy-duty material rack is very different in structure from the common heavy-duty material racks in the market. There is no motor and reducer inside the fuselage, which makes it impossible to use the motor and decelerate. The machine can achieve the effect of timely braking and braking. When the actual flattening machine is used, if the running speed of the leveling machine is fast (or the feeding speed of the feeding machine is too fast when it is directly matched with the feeder), it will produce the unpowered material frame. A large traction force, at which time the material frame will continue to rotate due to the inertia of operation, resulting in a large looseness of the material roll. Therefore, the unpowered heavy material frame is equipped with a brake device on the fuselage, which can ensure that the front position machine is lost. After the traction, the brakes are braked in time to eliminate the running inertia and ensure that the coil material does not appear bulk.
The main points of use of non-powered heavy-duty material frame: no-power heavy-duty material frame does not need to adjust the induction time, control operation and other steps like the commonly used heavy-duty material frame, but it also has its attention points when using it. First, according to the stamping production process. The demand (mainly related to the material width, thickness, and leveling feed speed requirement) adjusts the waiting area between the rack and the subsequent machine; the second is to adjust the tightness of the brake device, and the adjustment of the tightness can not be too loose. It can't be too tight. Too loose will cause the brakes to be braked in time. It does not effectively eliminate the looseness of the coil rotation and cause the looseness of the coil. Too tight will increase the load of the subsequent machine motor, which will not only affect the front machine. The use of the table, and will affect its service life, so the brake adjustment must be fine-tuned multiple times, the tightness of the brakes just to offset the inertia of its rotation.
