What are the advantages of the CNC bending with the move of the material support device?

When the CNC bending machine in the work process, we are bending thin plates or wider sheet metal parts, in order to prevent the workpiece deformation to ensure processing accuracy, often require the operator to manually bracket material, and sometimes rely on manual can not get more satisfactory results, then the follow-action front bracket mechanism is particularly important.

In order to meet the market demand, the major brands of sheet metal bending machines have introduced various modes of follow-me front bracket mechanism. From a comprehensive point of view, most of the bending machines adopt electro-hydraulic servo-controlled crank linkage mechanism.

The action of the crank linkage mechanism relies on the numerical control system to control the size of the opening of the proportional servo valve to adjust the amount of oil feeding the cylinder, so as to control the speed of the palletizing movement and the synchronization of the bending speed of the sheet. Relatively speaking, its mechanical action is complicated, and it also needs hydraulic cylinder for electro-hydraulic control, with high manufacturing cost and difficult to control the motion trajectory.

We think the whole structure composition of the front pallet mechanism: the power drive of this mechanism is mainly given by two servo motors. For different heights of the mold, in order to make the upper plane of the flap of the front pallet mechanism always on the same level with the upper plane of the lower mold, that is, the servo motor can drive the screw through the pulley to drive the whole slide to do up and down movement.

In the process of sheet metal processing, bending large plates is always a headache because the size of the plates is relatively large and the weight of the plates is also relatively large, so it often requires 3 to 4 people to bend a workpiece, which is labor-intensive and the accuracy of the workpiece is relatively low, and the operator is also tired.

The accompanying pallet device is a good solution to this problem, not only saves labor, but also improves production efficiency, and the accuracy of the workpiece is also much higher.

Bending machine pallet wheel frame using screw and tie rod mechanical transmission technology, pallet wheel frame in the process of use, to ensure that the pallet and the lower mold flush with the upper plane.

In the use of different heights of the mold need to raise or lower the pallet wheel frame, by triggering the rotating hand wheel, the rotating hand wheel and the left and right rotating screw coupling in the middle position, the left and right rotating screw using left and right rotating thread, respectively, with the left rotating thread nut and right rotating thread nut, the left and right rotating thread nut and the pallet wheel frame lift tie rod coupling, in the rotation of the rotating hand wheel through the left and right rotating screw rotating thread drive left and right rotating thread In the process of rotating the handwheel, the left and right rotating threads are driven by the left and right rotating threads through the left and right rotating screw.
