Because the part of the molded part outside the drawing die 200 is small, and the pickup area between the manual and the molded part is narrow, the ejection electric push rod 203, the ejection plate 202 and the manual cooperation are used to realize the unloading of the molded part. Compared with the manual direct picking method, the former can effectively avoid the probability of additional deformation of the molded parts during the discharging process, and at the same time, it is also convenient to manually pick up the molded parts more quickly and improve the production efficiency.

The reason why the combination of the ejector electric push rod 203 and the ejector plate 202 is selected to complete the discharging operation of the molded part, rather than the combination of the ejector electric push rod 203 and the inner mold 201 When the distance between the upper end faces of the drawing dies 200 , that is, the drawing depth has been adjusted, the drawing depth can be avoided due to multiple movements of the drawing dies 200 .

8 and 9, scale lines are engraved on the opposite end face of the side frame 204 and the front and rear ends of the upper end of the punching table 10. With the help of the scale lines on the opposite end face of the side frame 204, you can Accurately control and adjust the overall moving distance of the electric slider 205 and the template 231, that is, accurately control the distance between the upper end face of the inner mold 201 and the upper end face of the drawing mold 200, and then control the drawing depth, and it is also convenient to synchronously record the value of the moving distance. , in order to ensure the uniformity and uniformity of the drawing depth of the same batch of moldings.

Referring to FIG. 13 , an outer convex plate 24 is installed on the opposite end of the pressing electric slider 212 , a rectangular block is arranged at the lower left of the outer convex plate 24 , and the return block is installed on the opposite end of the floor frame 210 . The opposite ends are equidistantly clamped with horizontal bars 240 from top to bottom, and a single horizontal bar 240 is manually pushed to the right so that the right end of the horizontal bar 240 is located below the outer convex plate 24, and then the frame is driven by pressing the electric slider 212 The plate and the inner mold 201 move downward, and the outer convex plate 24 moves downward synchronously with the pressing electric slider 212. When the outer convex plate 24 contacts the right end of the horizontal bar 240, the pressing electric slider 212 stops moving. At this time, the circular ring plate 211 just presses the blanking disc, and selects the horizontal bar 240 at the corresponding position according to the thickness of the blanking disc, so that when the outer convex plate 24 is in contact with the horizontal bar 240, the circular ring plate 211 presses the blanking circle with an appropriate force. To avoid excessive compression, additional deformation of the blanked wafer before stretching occurs.

13, 14 and 15, a concave block is installed on the upper end of the stretching head 213, the concave block is installed on the lower end of the fixing plate, and the upper end face of the stretching head 213 is provided with an inner punching through hole, and the inner punching An inner punch 241 is slidably installed in the hole. An inner punch electric push rod 242 is connected between the upper end face of the inner punch head 241 and the lower end face of the fixing plate. The inner punch electric push rod 242 is located inside the concave block, and the stretching operation is completed. After that, the stretching head 213 is not separated from the formed part temporarily, and then the inner punch 241 is moved upward and then downward by the inner punching electric push rod 242 to punch the bottom end of the formed stretching part 21, and then By stretching the cylinder 214, the stretching head 213, the inner punch 241 and the inner punch electric push rod 242 are returned to the original position as a whole. When the inner punch 241 and the inner punch electric push rod 242 are used, the stretching member 21 At the same time, it has two functions of stretching and internal punching, and then a single production device can realize the forming of a shouldered sleeve shell with a through hole at the bottom end, and the production cost is reduced to a certain extent.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, and substitutions can be made in these embodiments without departing from the principle and spirit of the invention and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
