Preferably, the sliding plate 77 is made of copper alloy, and is in direct contact with the swing frame, so that not only can lubrication be achieved, but also replacement after abrasion can be achieved.
The working process of the balance system is as follows:
when the intermediate blank is required to be sheared and pressed, the eccentric crankshaft 1 rotates to drive the swinging frame 2 and the lower shearing and pressing device 6 to move upwards, and meanwhile, the hydraulic driving device 3 drives the upper shearing and pressing device 4 to move upwards under the guidance of the support wing plate 76, so that the shearing press for the intermediate blank is realized; in the shearing and crimping process, if the shearing blade is inclined due to uneven stress, the linear displacement sensor 78 can detect the position information in real time, and correct the shearing blade by controlling the expansion and contraction amounts of different hydraulic cylinders 74, so that the levelness of the shearing blade is always ensured; meanwhile, the hydraulic cylinders 74 positioned at the two sides of the shear blade also detect position information in real time, and once the difference is detected, the horizontal component force of the horizontal shearing force is too large to influence the swinging frame 2, and the horizontal component force of the shearing force is transferred to the vertical direction of the swinging frame by controlling the expansion and contraction amount of the hydraulic cylinders 74 at the two sides, and the strength of the vertical direction of the swinging frame is far higher than that of the horizontal direction, so that the overall stress distribution is optimized.
