Dieless Forming

The novel multipoint forming technology based on Hydro-forming processing was developed, and the drive mode was discussed. Die is replaced by liquid, and punch is formed by adjusting the multipoint fundamental elements. Finally through controlling the fundamental elements, the height of a serial of discrete, regularly-arranged fundamental elements is adjusted, and by using the punch pad, the accuracy of sheet metal surface contour is improved in multipoint forming technology. Then, the hydro-forming set was developed, and experimented. It provides a new efficient dieless forming method for the digital flexible forming of sheet metal.

Practical Recommendations

To determine the accuracy of the readjustable punches for separating operations (perforation + punching out) of sheet-metal forming, the accuracy parameters were analyzed using the random balance method using the method of experiment planning. Analytical dependencies are obtained to determine the values of deviation of the outer and inner contour dimensions of perforated and punched out sheet parts. From the dependencies obtained, it is possible to estimate and predict the value of deviation in the dimensions of the resulting part at any time during the operation of the punch. Practical recommendations on the calculation of the actuating dimensions of the working elements (stamping punch, matrix) of readjustable punches are offered.
