Under the action of second heating plate simultaneously squeezes plank, when avoiding the first heating plate and the second heating plate pressed sheet in
The phenomenon that heart deviates, will not make the first heating plate and the second heating plate torsional deformation, and then the damage of plank is avoided to deform, from
And improve the quality of product；3, when the first heating plate and the second heating plate are fallen down on workbench, there are pre- heat effect, and to plank
One hydraulic cylinder, second hydraulic cylinder push plate when close to the first heating plate, the movement of the second heating plate, wind is will produce, when blowing air over
When the first heating plate, the second heating plate, plank can be transferred heat to so that edges of plate material also fully heats, and then plank
Edge effect is good so that the performance of plank is reinforced；4, by the way that suction disk is arranged, when pushing plank, plank is sucked in suction disk
Bottom, can make plank in orbit steadily enter working region, convenient for compacting work；5, pass through the first heating plate and second
Heating plate heats the both sides of plank simultaneously, and plank is fast by thermal velocity, improves working efficiency.
Further, the height of track is more than the height of the first heating plate, the second heating plate apart from work top.When first plus
When hot plate, the second heating plate simultaneously suppress plank, it is ensured that monoblock plank is fallen in nip region, and then preferable real
Now to the compacting of monoblock plank, product quality is improved.
Further, plate surfaces are coated with heat-insulating material.Prevent the first heating plate heated and the second heating plate heat
Push rod is passed to, and then increases the utilization rate of heat, makes the first heating plate and the second heating plate that heat is adequately passed to plate
Material carries out heating compacting to it.
Further, the first heating plate and the second heating plate are made of cast iron.Cast iron is preferable electromagnetic heating material, is added
