The progressive die has a stable and high-speed feeding structure, including the upper die mechanism and the lower die mechanism;

The concrete structure of described patrix mechanism is as follows:

Including an upper mold base and a stripper plate, a nitrogen fixing seat is installed in the upper mold base, a threaded nitrogen gas spring is installed on the nitrogen fixing base, and the output end of the threaded nitrogen gas spring is fixed to a bearing installed in the nitrogen fixing base One end of the bearing seat is connected, the other end of the bearing fixing seat is connected with the penetrating guide sliding sleeve and the stripping plate, the guide sliding sleeve is matched with the stripping plate, and the end of the bearing fixing seat protruding from the stripping plate is connected by a bolt bearing;

The structure of the lower mold structure is as follows: it includes a lower mold lifting plate and a lower mold base, a plurality of lower mold nitrogen springs and inner guide sleeves are installed in the lower mold base, and the output end of the lower mold nitrogen spring is connected to the lower mold base. The material lifting plate abuts, one end of the inner guide column extends into the inner guide sleeve, and the other end of the inner guide column cooperates with the material lifting plate of the lower mold.

Its further technical scheme is:

A limit block for pressing the guide sliding sleeve is fixedly connected to the upper surface of the stripper plate.

The beneficial effects of the utility model are as follows:

The utility model has simple structure and is convenient to use. It utilizes bearings to press the workpiece material belt to make the workpiece material belt move forward stably. The mechanism occupies less space, which not only reduces the scrap rate of products, but also improves the production efficiency of products .

Detailed ways

The specific embodiment of the present utility model is described below.

As shown in Figure 1 and Figure 2, the stable and high-speed feeding structure of the progressive die includes an upper mold mechanism and a lower mold mechanism;

The specific structure of the upper mold mechanism is as follows:

Including the upper mold base 1 and the stripping plate 13, the nitrogen gas holder 10 is installed in the upper mold holder 1, the threaded nitrogen gas spring 9 is installed on the nitrogen gas holder 10, the output end of the threaded nitrogen gas spring 9 is connected with the nitrogen gas holder 10 One end of the bearing fixing seat 12 is connected, and the other end of the bearing fixing seat 12 is connected with the guide sliding sleeve 11 and the stripping plate 13. One end is connected to the bearing 15 through the bolt 14; the limit block 2 for pressing the guide sliding sleeve 11 is fixedly connected to the upper surface of the above-mentioned stripper plate 13.

The structure of the lower mold structure is as follows:

Including the lower die lifting plate 4 and the lower die base 7, a plurality of lower die nitrogen springs 8 and inner guide sleeves 6 are installed in the lower die base 7, and the output end of the lower die nitrogen spring 8 abuts against the lower die lifting plate 4, One end of the inner guide post 5 stretches into the inner guide sleeve 6, and the other end of the inner guide post 5 cooperates with the lifting plate 4 of the lower mold.

Concrete work process of the present utility model is as follows:

During the first stage, the upper mold mechanism and the lower mold mechanism are clamped. In this state, the output end of the threaded nitrogen gas spring 9 bears against the bearing holder 12, so that the bearing 15 is pressed on the workpiece material belt 3 all the time. During the second stage, the upper mold base 1 moves upwards. In this state, the stripping plate 13, the bearing holder 12 and the nitrogen holder 10 are stationary, and the bearing 15 still presses the workpiece material belt 3. In the third stage, when the stroke movement of the upper die base 1 is completed, the stripping plate 13 also moves upwards under the action of the upper die punch. During the upward movement of the stripping plate 13, the lower die lifting plate 4 passes through the lower die nitrogen spring 8 moves upward, when the stripping plate 13 is separated from the lifting plate 4 of the lower die, and when the stripping plate 13 is disengaged from the dead center of the punch, the disengagement distance is less than the formation of the threaded nitrogen spring 9, at this time the threaded nitrogen spring 9 Release and form a release pressure to the bearing holder 12, so that the bearing holder 12 transmits force to the bearing 15 and presses the strip all the time.

The utility model has simple structure and is convenient to use. It utilizes bearings to press the workpiece material belt to make the workpiece material belt move forward stably. The mechanism occupies less space, which not only reduces the scrap rate of products, but also improves the production efficiency of products .

The above description is an explanation of the utility model, not a limitation of the utility model. For the limited scope of the utility model, refer to the claims. Without violating the basic structure of the utility model, the utility model can be modified in any form.
