Description

TECHNICAL FIELD The present invention relates to an apparatus and a method for operating a scrap taking-out apparatus,

The present invention relates to a facility interlocking type product, a scrap taking-out apparatus and a method of operating the same, and more particularly, to a facility interlocking type product and a scrap taking-out apparatus in which scrap and product are separately separated and discharged, .

In general, fine blanking is a pressing process that obtains a good shear cross section and good product precision over the entire thickness of the product in a single blanking process.

Here, the word "FINE" means to obtain a precise and good surface, and since the blanking process is a shearing process to obtain the product, the press shear section has a complete shear section that does not require further machining It is possible to be.

The fine blanking process is performed by the following operating principle. First, before the shearing starts, the 'V' groove installed on the upper mold and the 'V' groove along the outer contour of the shear line to the material between the upper mold and the lower mold down so that the material does not move in the lateral direction. At the same time, the counter punch at the bottom of the blanking punch supports the bottom of the product to be sheared, and the shearing is performed while blocking the deformation in the longitudinal direction.

Since the shearing operation is performed in a state where the material is fixedly clamped, precise dimensions and smooth shear cross-section can be obtained.

In general blanking, a counter punch passes through a die hole to drop a product that has become a shear. In fine blanking, however, the blanking punch does not pass through the die hole, And is taken out of the mold by an air blower or a mechanical device for returning to the upper surface of the lower mold by punching and spraying the compressed air.

However, the above-described conventional techniques have the following problems.

The take-out of the workpiece by the air blower is performed by spraying high-pressure compressed air to the finished product in accordance with the upward and downward movement of the press.

This air blower method also requires a separate system and power for compressing the air, which increases the manufacturing cost, and the working environment is poor due to the noise (about 200dB) generated by the compressed air generated during the operation .

In addition, when the air blower is sprayed onto the workpiece, the workpiece is not taken out to a predetermined position, but scrap and the like after the workpiece and the work are scattered depending on the situation, thereby hindering the safety of the worker.

In addition, the compressed air dispersed in the air blower causes the workpieces to scatter in an unspecified direction, which causes the processed workpieces to collide with other structures such as scrap, .

This is because, due to the characteristics of the fine blanking, the processed product is completed without additional post-processing, thereby deteriorating the quality of the product and causing a defect, thereby seriously hurting the productivity.

In addition, the take-out of the processed product by the mechanical device can take out the processed product more stably than the take-out method using the air flow, but the configuration of the mechanical device for taking out the processed product without damaging the mold and the product is very difficult There is a problem that the structure is also complicated and the reliability of operation is deteriorated.
