Fig. 1-4, 14 have shown the realization form of the processing die of a kind of parking ratchet according to the present invention, which comprises:

The lower mold assembly 1 is provided with a fixed shaft 110 matching with the center hole of the blank 4;

The upper mold assembly 2 is provided with multiple groups of stamping tools 210 for processing the edge of the blank to obtain the tooth groove of the ratchet;

A plurality of sets of telescopic guide assemblies 3 connecting the upper mold assembly and the lower mold assembly;

Wherein, the lower mold assembly is provided with a plurality of avoidance areas 120 matched with the external structure of the stamping tool, each avoidance area corresponds to the position of each stamping tool in space, and the depth of each avoidance area is the same as that of each stamping tool. The descending depth is matched, and the design of this method enables the stamping tool to penetrate deep into the lower die during the stamping process to ensure that its stamping penetrates the blank. At the same time, the avoidance area can also store the corner waste generated by stamping.

The working principle is that the blank is first passed through the fixed shaft of the lower die assembly. Because the top of the upper die assembly is in direct contact with the hydraulic equipment, the force exerted by the hydraulic equipment causes the upper die assembly to drive the stamping tool downward, and the upper die assembly drives the punching tool downward, and During the downward process of the stamping tool, the blank set on the fixed shaft is stamped, and the ratchet tooth groove is obtained by stamping (or cutting) of the stamping tool, because the space arrangement of the stamping tool is consistent with the number of teeth of the ratchet tooth groove , so one stamping can get a plurality of corresponding ratchet tooth grooves to complete the processing of the parking ratchet, and it only takes about 10 seconds to process a parking ratchet, which effectively improves the production efficiency compared with the existing ones.

In another example, the upper end surface of the lower mold assembly is rotatably provided with multiple sets of first fixing assemblies 130 that define the periphery of the workpiece raw material. In practical applications, the blank is arranged behind the fixed shaft There may be eccentricity or rotation. Through the function of the second fixing component, the periphery of the blank is limited to prevent its rotation or eccentricity;

Wherein, the installation position of each first fixed assembly corresponds to the layout position of each cutter, and the outer side of each avoidance area is provided with an extension area 121 that restricts the downward rotation of the first fixed assembly, which is used to control the direction of the first fixed assembly. Accommodate when turning down to prevent it from interfering with the stamping tool.

Working principle, when the upper die assembly is not working, the first fixing assembly is set around the blank to limit it, and when the upper die assembly is punching downwards, the first fixing assembly slowly turns down and enters under the action of the punching knife. The extension area will not interfere with the work of the stamping tool, and at the same time ensure the stability of the blank during stamping.

As shown in Fig. 4, 6-8, in another example, the lower mold assembly is configured to include:

It also extends into the center hole to further limit the blank to ensure its stability during the stamping process. For blanks with low thickness, a cover plate can also be set below to control the blank from above. Press to ensure the stability of the blank during processing. This structure cooperates with the installation shaft and the first fixed component to limit the position of the blank in three ways to ensure that the later processing accuracy meets the needs;
