Embodiment Construction
[0013] Such as figure 1 , figure 2 with image 3 As shown, it includes blade 1, knife holder 2, knife beam 4, and ball screw 5. The knife holder 2 is fixedly connected with the ball screw 5. The blade 1 is fixed on the knife holder 2, and the ball screw is 5. The moving direction forms an angle a with the cutting edge side of the blade 1, and the cutting edge side of the blade 1 is parallel to the cutting edge side of the fixed blade. Also for inclined surface contact, turn the lead screw of the ball screw 5, the cutting edge side of the blade 1 and the moving direction of the ball screw 5 lead screw move at an angle a, and the cutting edge side of the left blade 1 and the cutting edge of the fixed blade The side distance increases, and the distance between the cutting edge side of the right blade 1 and the cutting edge side of the fixed blade decreases. Accurate adjustment of the side clearance of the cutting edge of the double crank flying shear is realized.

The invention belongs to the field of metallurgical equipment, in particular to a method for adjusting the side clearance of a double-crank flying shear in a cross-cutting production line. 1) Fixed on the knife seat (2), the moving direction of the ball screw (5) and the cutting edge side of the blade (1) form an angle a, the cutting edge side of the blade (1) and the cutting edge of the fixed blade The sides are parallel, the knife beam (4) and the side pressing block (3) are in inclined plane contact, and the side pressing block (3) and the knife seat (2) are also in inclined plane contact, and the lead screw of the ball screw (5) is rotated, The cutting edge side of the blade (1) and the moving direction of the ball screw (5) lead screw move at an angle a, the distance between the cutting edge side of the left blade (1) and the cutting edge side of the fixed blade increases, and the distance between the cutting edge side of the right blade (1) increases. The distance between the cutting edge side of ) and the cutting edge side of the fixed blade decreases. It has simple mechanism, convenient operation, high adjustment precision and short cutting time.
Description
technical field [0001] The invention belongs to the field of metallurgical equipment, in particular to a cutting blade side clearance adjustment method for double crank flying shears in a cross-cutting production line. Background technique [0002] In the cross-cutting production line, one of the important indicators of the quality of the finished sheet is the size of the shearing burr when the flying shear is cut. The value of the side clearance of the cutting blade should be accurate. In addition, output is also an important indicator of the production line. At present, the adjustment of the side clearance of the cutting edge of flying shears generally adopts the adjustment method of adding and subtracting gaskets on the back of the scissors and pushing and pulling the lower knife seat by bolts, which is not only time-consuming and laborious, but also has low adjustment accuracy. Contents of the invention [0003] The object of the present invention is to provide a met...
