Example:

As shown in Figure 2-3, when in use, the raw material of the workpiece is placed on the conveyor belt from the blanking part. When the workpiece reaches the first station, the upper template moves downward to drive the punch on the upper mold core to Moving down, the movable stripping plate at the end of the punch slowly falls under the support of the reset ejector rod. At this time, the first punch continues to fall and push the workpiece to the first profile to ensure that the movable stripping plate does not contact the outer edge of the workpiece, resulting in Squeeze; the upper mold core continues to fall and pushes the movable stripping plate to move downward, and at the same time, compresses the reset ejector pin downward.

When the mold is opened, the stop plate and the power transmission pin push the first floating block upwards, and the first floating block fixes the workpiece on the first punch. When the upper template continues to separate, the first floating block pushes the workpiece out of the first mold. On the other hand, at this time, the first punch continues to separate under the drive of the upper plate, and the movable plate can only rely on the reset ejector to rise slowly. The speed difference between the first punch and the first punch causes the workpiece under the first punch to be slowly The rising movable stripping plate is blocked to complete the stripping of the workpiece. The workpiece that has completed the first stamping will be stripped on the conveyor belt, and the conveyor belt will continue to move forward. Repeat the above process, and be stamped and formed step by step by the following multiple processes. Push the finished product on the conveyor belt into the discharge port.

This system also has different combined structures. The number of punches arranged on the upper template can be determined according to the number of processes. In addition, some punches do not need to be equipped with a retractable elastic reset ejector mechanism under the movable stripping plate, and some The retractable elastic floating block mechanism can adopt a structure in which the lower end of the simple floating block is connected with a contour screw, and a third spring is arranged in the lower template at the end of the contour screw.

The bottom of the floating block corresponding to the first punch is provided with a simple telescopic elastic structure.

In the process of separating the upper and lower molds, the reset ejector pin always bears against the movable stripping plate to prevent the movable stripping plate and the workpiece from being squeezed and deformed by the force in the process of feeding and stripping.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. Retouching should also be regarded as the scope of protection of the present utility model.
