Hydraulic two-side rolling-cut shears

Shears, comprising:

• a front transport roller device;
• the front transport roller device comprising a laser scriber, a magnetic alignment device, and a pinch roller device;
• a rear transport roller device;
• the rear transport roller device comprising a vertical guide roller;
• a shear body;
• the shear body comprising a first hydraulic rolling-cut shears and a second hydraulic rolling-cut shears;
• each of the first hydraulic rolling-cut shears and the second hydraulic rolling-cut shears comprising an entry pinch roll, an entry drive linkage, an entry rack, an upper beam, a pressing mechanism, an adjusting mechanism having pairs of movable wedges, a first upper tool post, a scrap chopping mechanism, an exit rack, an exit drive linkage, a lower tool post, an exit pinch roll, a turning device, and a connecting beam;
• and
• a roller carrier;
• wherein:
• the laser scriber is disposed on a front end of the front transport roller device;
• the magnetic alignment device is disposed in a middle part of the front transport roller device;
• the pinch roller device is disposed on a rear end of the front transport roller device and in front of the shear body;
• the roller carrier is disposed longitudinally in a middle of the shear body;
• the vertical guide roller is disposed on the rear transport roller device and behind the shear body;
• the first hydraulic rolling-cut shears is mounted on a movable base to form a movable hydraulic rolling-cut shears capable of moving on a guide rail;
• the second hydraulic rolling-cut shears is disposed on a fixed base to form a fixed hydraulic rolling-cut shears;
• the first hydraulic rolling-cut shears and the second hydraulic rolling-cut shears are symmetrically disposed;
• and
• in each of the first hydraulic rolling-cut shears and the second hydraulic rolling-cut shears:
• the entry pinch roll, the entry drive linkage, and the entry rack are disposed at an inlet of the respective shears;
• the exit rack, the exit drive linkage, and the exit pinch roll are disposed at an outlet of the respective shears;
• the entry pinch roll is disposed at a front end of the entry rack;
• the entry drive linkage is mounted on the entry rack and is connected to the upper beam and a front end of the first upper tool post;
• two ends of the upper beam are respectively mounted on upper parts of the entry rack and the exit rack;
• the first upper tool post is disposed at a middle between the entry rack and the exit rack, and is driven by the entry drive linkage and the exit drive linkage to move;
• the exit drive linkage is mounted on the exit rack, and is connected to the upper beam and a rear end of the first upper tool post;
• the exit pinch roll is disposed lower than the exit rack;
• the pressing mechanism is disposed on a first side of the first upper tool post;
• the adjusting mechanism is disposed on a top surface of the upper beam;
• the pairs of movable wedges are in contact with the first upper tool post;
• the lower tool post is disposed lower than the entry rack, the exit rack, and the first upper tool post;
• the turning device is mounted on a front end of the lower tool post;
• the connecting beam is disposed on a second side of the first upper tool post opposite to the first side of the first upper tool post;
• and
• the scrap chopping mechanism is disposed on the connecting beam at an inner side of the exit rack.
