The difference between two-in-one and three-in-one in the automatic feeder of the punching machine is as follows:
1. In terms of material width, 2-in-1 is more suitable for 200-600 materials, but the width of a pair of materials is not required, generally 300-1800mm or even wider.
2. In terms of structure, the three-in-one servo feeder combines the functions of the material roll holder, the loading trolley, the straightening machine and the feeder, which greatly reduces the area occupied by the conventional feeding device and can work with the punching machine at the same time. . The roll mounted on the roll holder is controlled by a sensor under the roll, and the NC feeder can be leveled on one side, and the material of a predetermined length is simultaneously fed into the punching mold. Although the two-in-one feeder has the straightening function of the rack, it has to be separately distributed and the floor space is larger.
3. According to the feeding principle, the principle of the three-in-one feeder is to axially move the end cover of the push rod driving end of the hydraulic device and the four wedge-shaped sliders, and then pull the curved tile through the connecting rod. Since the connecting block on the inner side of the curved tile is restricted by the limiting slider and the limiting baffle, it cannot move in the axial direction, and can only move radially along the radial strip hole on the limiting baffle, thereby achieving arc shape. The radial movement of the tile, that is, the contraction and tensioning; in the tension state, the starting power device drives the spindle to rotate through the sprocket mechanism, and the compaction device cooperates
4. In terms of operational performance, two-in-one generally takes ten minutes and requires more than two people to complete a loading process, while three-in-one from feeding, unwinding, leveling to feeding, giving a special person A set of feeding process can be completed in a few minutes, with high automation and easy operation.
5, from the precision point of view, three-in-one is better than two-in-one, because the three-in-one feeder is directly into the mold after leveling, and the two-in-one is first corrected and then fed, after the material arc, the leveling will still be Some changes, although not affecting the quality, but the operation is not so convenient; but if you send a very thin material, the two-in-one is better than the three-in-one. Now open. The two-in-one feeder drives the spindle through the belt of the reducer, and the spindle drives the material frame to rotate, thereby realizing the function of discharging and unwinding.
The three-in-one feeder is generally superior to the two-in-one feeder, but it is expensive and customers can choose the right product for themselves.
