Automatic blanking and ring cutting process

Abstract

The invention relates to an automatic blanking and ring cutting process, which comprises steps of a), blanking for obtaining a blank; b), positioning and pressing: descending a cross beam under action of a hydraulic piston and enabling a pressing tool to press and position the blank closely; c), cutting and forming: cutting from two sides of the blank by two groups or four groups of shearers and cutting a ring or annular workpiece by rotating a tool rest by semicircle; d), resetting a shearing device: ascending the shearing device to reset for the next operation cycle under action of the hydraulic piston after the tool rest completes rotating; e) discharging: moving an ejecting rod upwards under action of a lower main cylinder so as to eject workpieces out, sucking the workpieces and moving the same to be stored outside a machine tool under action of a sucker of a manipulator, and then moving an ejecting and vertical moving device downwards to reset for the next operation cycle. The automatic blanking and ring cutting process realizes automatic production and is high in processing speed and operation efficiency and low in waste of materials. Workpieces processed by the process are high in precision and quality.

Description

Technical field: [0001] The invention relates to the field of mechanical processing technology, and more specifically relates to an automatic production blanking and circle cutting process for cutting plates into circles or rings. Background technique: [0002] At present, manual cutting, die stamping and circular cutting machines can be used to cut the plate into a circle in the factory. Manual cutting is time-consuming and laborious, and the thickness and diameter of the cut plate are limited, and the dimensional accuracy of the finished product is low. Affect the quality of the product; the use of die stamping reduces the labor intensity, but it also requires workers to operate, and the cost of stamping dies is high; the use of a circular shearing machine needs to pre-cut the blank into a square, punch a center hole on the square blank, and put the blank into a After the center position of this automatic production blanking and cutting circle process is positioned, and th...

[0002] At present, manual cutting, die stamping and circular cutting machines can be used to cut the plate into a circle in the factory. Manual cutting is time-consuming and laborious, and the thickness and diameter of the cut plate are limited, and the dimensional accuracy of the finished product is low. Affect the quality of the product; the use of die stamping reduces the labor intensity, but it also requires workers to operate, and the cost of stamping dies is high; the use of a circular shearing machine needs to pre-cut the blank into a square, punch a center hole on the square blank, and put the blank into a After the center position of this automatic production blanking and cutting circle process is positioned, and the blank is fixed by the pressing device, the shearing device is adjusted to start cutting the circle, which wastes a lot of material and requires workers to operate. The noise is large during cutting, and the cutting section is not smooth. Flat, affecting the quality of the product
