The mould comprises a guide sleeve, an upper mould mandrel and an upper mould striking head, wherein the upper mould mandrel is connected in the guide sleeve in a sliding manner, the lower end of the upper mould striking head is connected with the upper end of the upper mould mandrel, and the lower end of the upper mould mandrel is elastically connected with an upper mould core positioned in the guide sleeve.

Description

Punching, flanging and flattening die

Technical Field

The utility model relates to a numerical control capstan head is towards processing and is clapped forming die, concretely relates to turn-ups flattening die punches a hole.

Background

The numerical control turret hydraulic punching press machine adopts an electrical signal to carry out position control of the up-down stroke, wherein the punching flanging flattening die comprises a guide sleeve, an upper die mandrel and an upper die striking head, the lower end of the upper die striking head is connected with the upper die mandrel, the lower end of the upper die mandrel is rigidly connected with an upper die core, and the upper die core is driven by the upper die striking head to punch downwards so as to flatten the punching flanging. Because of the corresponding time of the sensor, the controller, the electromagnetic valve and the like, the deviation occurs during the precise forming processing, and particularly, when the equipment is used for a long time, the larger the deviation is, the more the deviation is outstanding.

Through technical analysis, the existing bottom dead center positioning mode of numerical control hydraulic punching cannot achieve accurate positioning, and the cost for replacing the punching machine tool is very high.

SUMMERY OF THE UTILITY MODEL

The to-be-solved problem of the utility model is to provide a turn-ups flatting die punches a hole utilizes the elastic compression volume to revise the bottom dead center deviation of punch press.

The utility model discloses a realize through following technical scheme:

the utility model provides a turn-ups flattening die punches a hole, includes the guide pin bushing, goes up the mould dabber and goes up the mould striking head, it is in to go up mould dabber sliding connection in the guide pin bushing, the lower extreme that goes up the mould striking head is connected go up the upper end of mould dabber, the lower extreme elastic connection that goes up the mould dabber has and is located the last mold core in the guide pin bushing.

Further, the upper end of going up the mold core is equipped with the connecting axle, it is equipped with hollow chamber to go up the mold core axle, hollow intracavity is equipped with the backup pad, it has the screw that can reciprocate to run through in the backup pad, the lower extreme threaded connection of screw is in on the connecting axle, the cover is equipped with spring element on the connecting axle, spring element's upper end is supported go up the lower extreme of mold core axle, the lower extreme supports the upper end of going up the mold core.

Further, the spring element is a belleville spring, and the lower end of the upper die striking head is in threaded connection with the upper end of the hollow cavity.

Compared with the prior art, the utility model the beneficial effect who gains as follows:

1. the upper and lower dies are formed in place at one time, the punch forming standard of each time has no deviation, the elastic compression amount of the upper die core is utilized to correct the deviation of a bottom dead center, and the precise forming is realized under the condition of not replacing a punch;

2. the belleville spring has good compression performance, and the deviation of a bottom dead center is guaranteed to be corrected;

3. the utility model discloses simple structure, operation easy maintenance.

Drawings

FIG. 1 is a schematic structural view of the punching, flanging and flattening die of the present invention;

FIG. 2 is a state diagram of the punching, flanging and flattening die of the present invention matching with a lower die;

in the figure: 1. the device comprises a guide sleeve, 2, an upper die mandrel, 3, an upper die core, 4, a spring element, 5, an upper die striking head, 6, a connecting shaft, 7, a screw, 8 and a lower die.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

As shown in fig. 1, the present embodiment discloses a punching flanging and flattening die, which includes a guide sleeve 1, an upper die core shaft 2, an upper die core 3, a spring element 4 and an upper die striking head 5. The guide sleeve 1 is fixedly arranged on a machine tool, the upper die core shaft 2 is connected in the guide sleeve 1 in a sliding manner, a circular hollow cavity is processed in the upper die core shaft 2, and the lower end of the upper die striking head 5 is connected to the upper end of the hollow cavity in a threaded manner. Go up the upper end of mold core 3 and be equipped with connecting axle 6, processing has annular boss to act as the backup pad in hollow intracavity, runs through the screw 7 that has the ability to reciprocate in the backup pad, and the lower extreme threaded connection of screw 7 is on connecting axle 6, and the cover is equipped with spring element 4 on connecting axle 6, and the upper end of spring element 4 supports the lower extreme of last mold core axle 2, the upper end that the lower extreme supported last mold core. To ensure a good elastic compression, the spring element 4 is a disk spring.

The utility model discloses a turn-ups of punching a hole flattening die working process is as follows:

as shown in fig. 2, the downward depth of the upper die striking head is adjusted to be over-travel, when the upper die striking head moves downward, the upper die core shaft drives the upper die core ejection guide sleeve to be matched with the lower die 8 located below to perform one-time flattening forming on the punching flanging, when the upper die core moves downward and meets enough resistance, the elastic element begins to contract, the deviation of a bottom dead center is corrected through the elastic compression amount of the disc spring, and accurate forming is realized under the condition that a punch press is not replaced.
