Strip stamping, hydraulic heavy-duty material frame, automated stamping

Working principle of hydraulic heavy material frame: high-pressure oil enters the closed cavity composed of hydraulic cylinder shell and piston through the axial through hole in the main shaft and the piston rod. When the hydraulic pressure reaches a certain value, the piston is in the oil. The axial movement along the outer casing of the hydraulic cylinder is generated.

The axial movement of the piston causes the sliding mounting sleeve to move axially relative to the main shaft of the material frame. Since the fixed mounting sleeve is fixed relative to the main shaft, the axial movement of the sliding mounting sleeve relative to the main shaft causes the sliding mounting sleeve and the shaft of the fixed mounting sleeve Change to distance.

At this time, there is a triangular connection relationship between the connecting piece and the Y-shaped joint and the sliding mounting sleeve and the fixed mounting sleeve, and the axial distance between the sliding mounting sleeve and the fixed star-shaped sleeve is changed, so that the material rack material panel is widened away from the main shaft.

Therefore, under the driving of the oil pressure, the material shingle plate is widened away from the main shaft, so that the diameter of the cylinder composed of the material shingle plate becomes larger, and the inner hole of the coiled steel plate is tightened to realize the winding circle. The fixing of the steel plate.

Conversely, when the high-pressure oil passes through the axial through-holes in the main shaft and the piston rod and is withdrawn from the closed cavity, the hydraulic pressure in the cavity formed by the hydraulic cylinder casing and the piston is small.

The external atmospheric pressure causes the sliding mounting sleeve and the piston to move axially away from the fixed mounting sleeve, so that the diameter of the cylinder composed of the material shingle plate becomes smaller, preparing for the next tightening and fixing the round steel plate, and the cylinder diameter is realized below. The size of the change.

In addition, the flat key is fixed on the main shaft, and when the material frame main shaft rotates, the sliding mounting sleeve can be driven to rotate around the spindle axis, and the I-shaped member and the connecting member are driven to rotate around the spindle axis, so that the material frame is rotated. The shaft of the cylinder of the plate is rotated to realize the discharge function.
