Description

Material belt detection positioning mechanism of progressive die

Technical Field

The utility model relates to a continuous stamping die especially relates to a material area of modulus of continuity detects positioning mechanism.

Background

Stamping forming is an important processing technology which is indispensable in the industrial processing field, and a progressive die is a more advanced device in stamping processing. The automatic punching machine can send coil materials or plates into a continuous die through an automatic feeding machine, and can realize various processes of punching, trimming, bending, marking, forming, blanking and the like in one-time punching stroke. Therefore, the progressive die is a stamping die with multiple stations, high precision, high efficiency and automation.

Because the number of the continuous dies is large, the problem of accurate positioning of the material belt must be solved in the automatic stamping process, and the quality of the stamping part and the safety of the die can be ensured. The processing process comprises the steps that after the coiled material is discharged by the discharging machine, the feeding machine sends the material belt out for a fixed length, and then the material belt is punched after being guided into the positioning hole in the material belt by the guide column in the die. However, in actual production, the alternating current contactor and the relay contact inside the discharging machine reach the service life and can not discharge materials, oil stains cause the feeding machine to slip, and factors in various aspects such as coil stock deformation can cause the feeding machine not to be conveyed to the correct position, so that the material belt is misplaced to cause the mold to be seriously damaged.

The traditional solution is as follows: during design, a mechanical misdelivery detection probe is arranged in the die. The principle is that before the guide probe is positioned, if the positioning hole deviates, the detection probe can be jacked up to drive the dowel bar to touch the microswitch, so as to give a signal to the punch press to stop the punch press. But in actual production, a plurality of continuous dies are found to have no or forget to design the detection probes during design, so that the difficulty of assembling the detection probes in the later period is increased, the assembly is not in place, and if the springs are broken, the micro switch can not accurately act, so that the dies are misplaced. What is more critical is that the detection probe can be effective only after the upper die descends to a certain distance from the upper die to the material belt, and the die is closed quickly due to inertia when the punch press is stopped, so that the die parts are damaged frequently.
