Problems solved by technology

[0002] Plate deep drawing is a very common process. When the plate is deep drawn, it is easy to cause the deformation of the edge of the deep drawing under the action of the punch and the die. At this time, the blank holder is often used to pad the plate to avoid Deformation, but when drawing holes of different sizes in the deep drawing work, it is necessary to replace the blankholders of different sizes corresponding to the sizes of the punch and die, which increases the manual operation steps and requires demoulding after drawing Only then can the drawing of the next plate be carried out, which also increases the manual operation steps. Such drawing process requires a lot of manpower and is very troublesome. An automatic drawing stripping machine with adjustable blank holder size explained in the present invention can solve the problem of above question

Abstract

The invention discloses an automatic deep drawing demoulding machine capable of adjusting the size of a blank holder. The automatic deep drawing demoulding machine comprises a punching machine, an upper cavity is formed in the punching machine in a left-right penetrating mode, a lower cavity with an upward opening is formed in the lower wall of the upper cavity in a communicating mode, a main motor is fixedly arranged in the rear lower side of the punching machine, and the upper end of the main motor is in power connection with a vertical screw rod. According to the automatic deep drawing demoulding machine, drawing work can be conducted on a plate, when a male die and a female die conduct drawing on the plate, the blank holder can be used for pressing the plate, edge deformation of the plate during drawing is prevented, after the specifications of the male die and the female die are changed, the size of an inner hole of the blank holder can be automatically adjusted to adapt to the corresponding female die and male die, manual replacement is not needed, operation steps are reduced, the plate can be automatically demolded after being drawn, and time and labor are saved.
