Description

A multifunctional punch turntable structure

technical field

The utility model relates to a multifunctional punching die, which belongs to the field of mechanical processing.

Background technique

The punch die is the "accessory" corresponding to the punch. The workpiece is plastically deformed under the combined action of the stamping of the punch and the resistance of the die to complete the processing process. The precision of the punch die determines the processing accuracy of the workpiece to a large extent. Ordinary punching dies are single punching holes. If multiple shapes are punched during production, different dies must be replaced. The operation is cumbersome and must be installed in place during installation, otherwise the production process will be affected.

Further, the punch turntable 2-2 is connected with the upper die base 2-1 through the rotating shaft 2-5, and the rotating shaft 2-5 is a ratchet structure; the punching turntable 3-2 is connected with the lower die base 3-1.

Further, rotating holes 2-6 are provided on the periphery of the rotating disk.

Further, a through hole 3-4 is provided between the lower mold base 3-1 and the base 4.

Beneficial effect

1. The device is equipped with a punch turntable 2-2 and a matching punch turntable 3-2. By turning the turntable, selecting matching punches, and punching for processing, there is no need to replace molds, reducing cumbersome operations for replacement and inaccurate positioning.

2. The turntable is connected with the mold base through a ratchet device, which is easy to adjust and determine the position of the turntable.

3. The periphery of the turntable is provided with a turn hole, which can be inserted into an iron rod or the like to turn the turntable.

4. A through hole is arranged in the middle of the lower mold base 3-1 and the base 4, and the module pressed out during processing automatically falls from the through hole.

Detailed ways

The structure of a multifunctional punch turntable provided by the present invention will be further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 and FIG. 3 , it is an appearance view of a multifunctional punch turntable structure provided by the utility model, including a mold handle 1 , an upper mold 2 , a lower mold 3 and a base 4 . The upper die 2 is fixed with the press slider through the die handle 1; the upper die 2 is provided with a punch turntable 2-2 and a plurality of punch guide sleeves 2-3, and the turntable is provided with at least two punches 2-2 of different shapes. 4 devices; the lower mold 3 is fixed on the mold base 4, and the mold is provided with a punching turntable 3-2 and a guide post 3-3 correspondingly matched with the punch 2-4. When processing the workpiece, rotate the punch turntable 2-2 to select a suitable punch 2-4, and at the same time adjust the punch turntable 3-2 to a suitable position, and place the material plate for processing.

As shown in Fig. 1 and Fig. 4, it is a perspective view shown in the utility model, by upper die base 2-1, punch turntable 2-2, punch guide sleeve 2-3, punch 2-4, rotating shaft 2-5 and Turn hole 2-6 to form. The punch turntable 2-2 is connected to the upper die base 2-1 through the rotating shaft 2-5, and the rotating shaft 2-5 is a ratchet structure, which is a single-acting ratchet, so that the turntable can only rotate counterclockwise; There are at least two punches 2-4 of different shapes. Before the mold is installed, the appropriate punches 2-4 can be selected according to the needs; there are rotating holes 2-6 around the turntable, which can be inserted into iron rods to turn the turntable. It is convenient to rotate and does not affect the device; the punch guide sleeve 2-3 is fixed on the upper die base 2-1, and is used in conjunction with the guide post 3-3 fixed on the lower die base 3-1 to play a guiding role.
