Description

Positioning guide device applied to sheet punching die

Technical Field

The utility model relates to a positioning and guiding device applied to a sheet stamping die, and belongs to the technical field of punch auxiliary tools.

Background

In the prior art, the punching width of the existing die of the punch is large, the existing width is 200mm, and the existing die does not have the function of width adjustment, when sheets with different width dimensions are punched, the sheets are easy to swing back and forth and cannot be effectively restrained, and in-process punching dislocation is caused to generate defective products which cannot meet the use of the next procedure, so that the yield and the quality of the procedure are influenced, and the unit cost is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a positioning guide device applied to a punching die of a sheet punching machine, thereby overcoming the defects of the prior art.

The utility model is realized by the following technical scheme that the punching die comprises a punching machine workbench and a punching die, wherein the punching die consists of an upper die and a lower die, the lower die comprises a stripper plate, a lower die holder and a positioning and guiding device;

the stripper plate is connected with the lower template,

the lower template is connected with the lower die holder,

the lower die holder is fixedly arranged on a workbench of the punch press;

the positioning guide device comprises two positioning guide rods which are oppositely arranged, and each positioning guide rod consists of a positioning rod which is horizontally arranged and a guide rod which is vertically arranged; when the punching die is used, the number of the positioning guide rods arranged on the stripper plate is adjusted, so that the purpose of punching sheets of different specifications and models is achieved.

The positioning rod is provided with two connecting holes and is fixedly connected with corresponding screw holes on the stripper plate through screws.

The positioning and guiding device has an outward included angle at two ends of the punching die, and has a certain guiding effect on the sheet material during feeding.

The height of the guide rod is slightly larger than that of the positioning rod.

The utility model has the advantages that compared with the prior art: [1] the device is simple to manufacture and has strong practicability; [2] the guide position is correct, the punching position is accurate, defective products are reduced, and the requirements of multiple specifications are met; [3] the yield and the quality of production are improved, and the unit cost is saved.

Detailed Description

To facilitate a further understanding of the present invention by those skilled in the art, embodiments of the present invention are further described below with reference to fig. 1 to 6:

the utility model comprises a punch press workbench 1 and a punch die 2, wherein the punch die consists of an upper die 21 and a lower die 22,

the lower die 22 comprises a stripper plate 221, a lower template 222 and a lower die base 223, and further comprises a positioning guide device 3;

the stripper plate 221 is connected with the lower template 222, and is provided with a guide hole for guiding a punch, stripping materials and pressing materials;

the lower template 222 is connected with the lower die base 223, and is provided with a punching hole for punching and blanking sheets;

the lower die holder 223 is fixedly mounted on the punch press workbench 1 and used for fixing the lower die plate 222 and matching with the upper die 21 to enable the upper die 2 to be well matched and blanking under the guide of the guide post.

The positioning guide device 3 includes two positioning guide rods 31 oppositely arranged, as shown in fig. 6, the positioning guide rods 31 are composed of positioning rods 311 horizontally arranged and guide rods 312 vertically arranged;

the positioning rod 311 is provided with two connecting holes 313, and is connected and fixed with corresponding screw holes 2211 on the stripper plate 221 through screws 314.

The width of the currently produced sheet is 200mm, 150mm and 100mm, and when the sheet punching machine is used, the purpose of punching sheets of different specifications and models is achieved by adjusting the number of the positioning guide rods 31 arranged on the stripper plate 221.

When two positioning guide rods 31 are installed at the same time during production, as shown in fig. 3, the width of the produced sheet is 100 mm; when any one of the positioning guide bars 31 is installed, as shown in fig. 4, the sheet is produced to have a width of 150 mm; when the two positioning guide rods 31 are not installed, as shown in fig. 5, the width of the produced sheet is 200mm, which is equivalent to the prior art.

The positioning guide device 3 has an outward included angle at two ends of the punch die 2, and plays a role in guiding the sheet material during feeding.

The height of the guide bar 312 is slightly greater than the positioning bar 311. The distance between the stripper plate 221 and the lower die plate 222 is 8mm, the height of the positioning rod 311 is smaller than the height between the stripper plate and the lower die plate, the height is set to be 6.5mm, the maximum thickness of the sheet is 2mm, and the die 2 can simultaneously punch three sheets at present.

Through the effect of the positioning and guiding device 3, the size of the feeding hole can be adjusted, the sheets with different widths can be dealt with, the yield of products is improved, and the unit cost is greatly reduced.
