The material moving device of the stacking-descending pallet moves up and down along the vertical direction all the time within the stroke delta h range to realize the lifting action and complete the material receiving and discharging actions of the blank 4.

Firstly, a material receiving process:

the piston rod of the plunger cylinder 801 of the lifting mechanism 8 extends to drive the connecting rod 601 of the four-bar linkage 6 to move upwards, further drive the crank 602 and the synchronizing shaft 604 to rotate anticlockwise, the bearing platform 1 rises to the position where the initial receiving material is the index height + a, and the blank 4 slides along the upper surface of the round steel 3 until all the blank enters the upper part of the bearing platform 1.

Secondly, discharging:

at the initial unloading position elevation + b, the blank 4 slides along the upper surface of the round steel 3 until the blank completely leaves the upper part of the bearing table 1 and enters a conveying roller way. At the moment, the retraction stroke of a piston rod of a plunger cylinder 801 of the lifting mechanism 8 is equal to the thickness delta of one blank 4, a connecting rod 601 of the four-bar linkage 6 is driven to move downwards, a crank 602 and a synchronizing shaft 604 are driven to rotate clockwise, the height of the bearing platform 1 which is lowered from the initial unloading position elevation + b is delta, and the blank 4 slides along the upper surface of the round steel 3 until all the blank leaves the upper part of the bearing platform 1 and enters a conveying roller way. And repeating the action until the bearing table 1 descends to the final unloading position elevation + a, and at the moment, the Nth follow blank 4 completely leaves the upper part of the bearing table 1 and enters a conveying roller way. When the discharging from the first billet 4 to the last billet 4 is completed, the stroke length Δ h of the plunger cylinder 801 is equal to N δ, and the lifting mechanism 8 retracts to the minimum stroke.

In the whole material receiving and discharging process, the lifting height of the equipment is delta h stroke displacement from the highest point to the lowest point within the range of clockwise rotation angle theta of the crank throw 602.

When the four-bar mechanism 6 is used for receiving and discharging materials, the whole mechanism is high in lifting synchronism and stable and reliable in lifting, and the bearing platform 1 is ensured to be in a horizontal state constantly in the lifting process; the pin shaft and the joint bearing of each hinge point eliminate the mechanical blocking phenomenon in the lifting process and ensure the smoothness of the lifting action.

The ball panel 7 is arranged at the lower parts of the plunger type cylinder head 803 at the end part of the lifting mechanism 8 and the bearing platform 1, the ball panel 7 has self-adaptability to errors caused by mechanism abrasion, the weight of the bearing platform 1 can be balanced, the defects of large yield stress at the end part of the plunger type cylinder head 803, unbalanced loading of a cylinder body, abnormal abrasion of a cylinder wall and the like are overcome, the parallelism of the whole lifting mechanism is ensured, and the vertical lifting function of equipment is realized.
