Abstract

The utility model discloses a 90-degree bent hardware die for solving the problems that the produced component is unstable in bending at the angle of 90 degrees, the die is often repaired and transferred, the die is required to be transferred and repaired again at the formation angle of 90 degrees when the next batch of stamping materials are replaced, the production efficiency is low, and meanwhile, the materials are wasted due to the frequent die repair. The 90-degree bent hardware die is characterized by comprising a lower die plate and a lower die movable slide block, wherein the lower die plate is internally provided with a lower die bending block; an upper die bending punch is arranged above the lower die bending block; a lower die guide block and a slide block are arranged inside the lower die movable slide block; an upper die slide block is arranged above the lower die movable slide block; and the lower die plate is also provided with a fine adjusting spring and an adjusting block. By using the 90-degree bent hardware die, the beneficial effects of increasing the production efficiency and reducing material waste are achieved.

Description

90 ° of bending hardware dies

Technical field

The utility model relates to a kind of continuous hardware stamping die, especially for 90 ° of tolerances of bending be ± 1 ° to the inside crooked thin material product shaping a kind of 90 ° of bending hardware dies.

Background technology

The thin material product of existing hardware stamping bending and forming is a kind of processing mode that is shaped under the punch press pressure-acting by continuous hardware stamping die.Present existing hardware dies is ± 1 ° to 90 ° of tolerances of bending; usually the forming mode of use has 90 ° of shapings to add adjustment; mould rushes speed when producing and only has 300SPM; and 90 ° of bendings of the component of producing are unstable; often repair a die, mode transfer is when changing a collection of stamping material; 90 ° of shaping angles need again the mode transfer maintenance, and low often the repairing a die simultaneously of production efficiency also wasted material.

Summary of the invention

The purpose of this utility model is: a kind of 90 ° of bending hardware dies are provided, exist 90 ° of bendings of component of producing unstable to solve prior art, often repair a die, mode transfer, when changing a collection of stamping material, 90 ° of shaping angles need again the mode transfer maintenance, and production efficiency is low often to repair a die simultaneously, the problem of waste material.

Reaching the technical scheme that the purpose of this utility model takes is: a kind of 90 ° of bending hardware dies, it is characterized in that: comprise lower bolster, the movable slide block of counterdie, lower bolster inside is provided with the counterdie folded block, counterdie folded block top is provided with patrix bending punching, the movable slide block of counterdie inside is provided with counterdie guide pad and slide block, is provided with mode slider above the movable slide block of counterdie; Lower bolster also is provided with fine setting spring and adjustment block.

Adopt the utility model the side-play amount of 0.10-0.15MM specially to be arranged being shaped 45 ° the time to wrap direction, (the bending line forming process staggers) reshapes 90 °, after adopting this measure can guarantee twice bending, 90 ° of sizes reach dimensional requirement substantially, adding small adjustment work station, 90 ° of sizes of bending reach dimensional requirement fully.

The beneficial effect that the utility model reaches is: adopt the utility model, newly increased before 90 ° of bendings and be shaped 45 °, move 0.10-0.15MM left and right (012) at 45 ° of bending points to wrap direction, make the resilience of material when reducing by 90 ° of bendings, reached the beneficial effect of enhancing productivity and reducing the waste of material.

Description of drawings

Fig. 2: 90 ° of structural representations of shaping of the present utility model.

Fig. 3: fine setting shaping structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, architectural feature of the present utility model is described more at large.

With reference to Fig. 1,2,3, lower bolster 001, patrix bending punching 002, counterdie folded block 003, upper mode slider 004; the movable slide block 005 of counterdie, patrix bending punching 006, counterdie guide pad 007, slide block back-moving spring; 008, fine setting piece 009, fine setting spring 010, adjustment block 011.

After this mould assembly is good, die trial success, 90 ° of bendings put in place when second station is shaped substantially, add small 90 ° of bendings of adjustment work station adjustment and reach dimensional requirement fully, the proof front is used " minute two-stage forming+adjustment, the bending point carries out suitable translation " method has effect preferably.In design afterwards, I once repeatedly used, and all received good result.In actual production, mould production is stable, and SPM is promoted to 800 times/minutes by 300 of former Come, improving productivity 50%.

When cross component force is larger in bending and forming, becoming shape Red to be subjected to force direction to add a spacing/guiding die, can have effect separate 90 ° of Form springbacks of Decision excessive ask Questions.

Claims

1. 90 ° of bending hardware dies, it is characterized in that: comprise lower bolster (001), the movable slide block of counterdie, lower bolster inside is provided with the counterdie folded block, counterdie folded block top is provided with patrix bending punching (002), the movable slide block of counterdie inside is provided with counterdie guide pad and slide block, is provided with mode slider above the movable slide block of counterdie; Lower bolster also is provided with fine setting spring and adjustment block.
