AI Technical Summary
During the demolding process of existing stamping presses, the edges of the sheet metal are prone to deformation due to uneven friction and thrust, resulting in unsmooth demolding.
The side templates and parting components are symmetrically distributed. Synchronous movement is achieved through the meshing of L-shaped racks and gears. Combined with the inclined surface transmission of arched plates and trapezoidal blocks, the lifting and parting are carried out simultaneously, reducing single-point stress, increasing contact area, and avoiding the influence of friction.
It enables quick demolding of the plates, reduces edge deformation, improves demolding stability and accuracy, simplifies the operation process, and reduces energy consumption.
