In the current stamping production process, most of the heavy-duty material racks are used to place the coils. The heavy-duty material rack consists of two main structural components: the base and the spindle mounted on the base. The main shaft is additionally provided with a backrest wheel and a support. The block, the expansion and contraction reel, the coil material is placed on the main shaft expansion and contraction reel to realize the discharging and unwinding. When the heavy material frame is used, when the roll of material is used up, the whole production line needs to be stopped and the reel is reloaded. Because the material rack carries a large weight of the coil material, it requires a long charging time, and the earth limits the effective working time of the entire stamping production line; on the other hand, the single-axis discharging method of the heavy material rack ensures uniform torque. The main shaft can only be placed in the center of the base, so that the loose shaft and the tilting of the rotating shaft will not occur, but the charging is very inconvenient.
double-head material rack is a new rack equipment that truly solves the cumbersome material loading and time-consuming materials. The double-head material frame has a round-shaped base on the bottom, and the base adopts a thick and thin structure to effectively reduce the center of gravity of the rack, and a rotating seat is pivotally connected above the base, and the rotating seat is symmetrical on one side. The shaft body and the shaft body are composed of a fixed shaft and two expansion and contraction rolls wrapped around the fixed shaft. The design of the two expansion and contraction rolls ensures that the material frame can simultaneously place two coils.
When the double-head material frame is used, two rolls of material can be set on both sides of the expansion and contraction reel. When one roll of material is used, the rotary seat can be rotated through 180° and directly replaced with another roll of material. When another roll of material is used, the new roll is reloaded to the expansion and contraction roll, so that the entire production line is not required to wait for the loading process of the roll during the entire production line stamping production process, thereby fundamentally improving the production efficiency; The two rolls are loaded on both sides of the same fixed shaft, so the torque on the base and the rotating base is very small, the overall structural stability is high, and the service life of the material frame is fundamentally ensured.
