The invention discloses a shear edge backlash adjusting system for a cold-rolling hydraulic shear. A lower tool apron is fixedly mounted in a lower rack, a lower shear edge is fixedly mounted in the lower tool apron, an upper tool apron is mounted in an upper rack in a line rolling direction in a sliding manner, and an upper shear edge is fixedly mounted in the upper tool apron. The front end of the upper tool apron is in transmission connection with the inner ends of two adjusting bolts, each adjusting bolt is arranged in one adjusting nut in a sleeving manner, and the two adjusting nuts are both fixed in the upper rack. The rear end of the upper tool apron is abutted with a piston rod of a locking hydraulic cylinder. A rocker arm is fixedly mounted at the outer end of each adjusting bolt in the radial direction, one rocker arm is in transmission connection with the piston rod of the hydraulic cylinder through a connecting rod, and the other rocker arm is in transmission connection with the connecting rod through a coordination rod. The device uses one hydraulic cylinder to realize the continuous adjustment of the shear edge backlash, improves the adjusting automation of the shear edge backlash, is simple in structure, reduces the cost, and improves the stability, economy, safety and reliability of the system.
Description
technical field [0001] The invention belongs to the technical field of cold rolling machinery and equipment, and relates to a side clearance adjustment system of hydraulic shearing blades for cold rolling. Background technique [0002] In the cold rolling production process, hydraulic shears are often used to cut the head and tail of the strip or cut off the defective part. With the continuous improvement of rolling speed and production capacity, higher and higher requirements are put forward for the performance of hydraulic shears. When the rolling specifications are changed, the shear blades are slightly worn and need to be adjusted, and the shear blades are severely worn or damaged and need to be replaced, the relative positions of the shear blades need to be adjusted. The adjustment of the cutting edge includes the adjustment of the relative side clearance and the overlapping amount of the cutting edge. Whether the design of the cutting blade adjustment mechanism is re...
