Abstract
The utility model discloses a sheet punching die and a sheet punching device, the sheet punching die comprises a die body, wherein the die body is provided with a through blanking hole; the blanking hole is a step hole, the step hole comprises a first hole section connected with the top surface of the female die body and a second hole section with the hole diameter smaller than that of the first hole section, and the second hole section extends to the bottom surface of the female die; wherein the diameter of the first hole section is consistent with the aperture of a hole which is made by punching the sheet material; the height of the first hole section is not less than the thickness of the sheet. The utility model provides a die-cut die of sheet and die-cut device of sheet makes first hole section through the oral area at the die, and when the sheet was die-cut system hole, the waste material under the die-cut sinks the card in small-size second hole section along with a slice of accumulation of going into of drift, just can solve the condition of jumping the waste material.
Description
Technical Field
The utility model relates to a die-cut field, it is specific relates to a die-cut die of sheet and die-cut device of sheet.
Background
Punching devices are generally adopted for hole making of metal sheets, each punching device comprises a male die and a female die, when the male dies are pressed downwards, a punch head of each punching device can shear the metal sheets between the male dies and the female dies, and when the punch heads stretch into blanking holes in the female dies, cut waste materials are pressed into the blanking holes, and the waste materials are discharged from the blanking holes in a falling mode.
However, due to the high-speed processing of the punching device, sometimes the waste materials do not fall into the blanking hole and fly out from the gap between the male die and the female die, the waste materials are commonly called as jumping waste materials, the jumping waste materials are not only easy to cause personal and equipment injuries, but also bring troubles for the subsequent waste material collection.
SUMMERY OF THE UTILITY MODEL
The utility model provides a die-cut die of sheet and die-cut device of sheet for solve above-mentioned technical problem.
In order to solve the technical problem, the technical scheme of the utility model is that:
a sheet punching female die comprises a female die body, wherein a through blanking hole is formed in the female die body;
the blanking hole is a step hole, the step hole comprises a first hole section connected with the top surface of the female die body and a second hole section with the hole diameter smaller than that of the first hole section, and the second hole section extends to the bottom surface of the female die;
wherein the diameter of the first hole section is consistent with the aperture of a hole which is made by punching the sheet material; the height of the first hole section is not less than the thickness of the sheet.
Further, when the thickness of the sheet is between 0.1 mm and 1mm, the difference between the diameters of the first hole section and the second hole section is 0.02 mm.
Further, when the thickness of the sheet material is between 1-2mm, the difference between the diameters of the first hole section and the second hole section is 0.04 mm.
Further, when the thickness of the sheet material is more than 2mm, the difference between the diameters of the first hole section and the second hole section is 0.06 mm.
The utility model also provides a die-cut device of sheet, it includes as above the die-cut die of sheet.
The utility model has the advantages of as follows:
the utility model provides a die-cut die of sheet and die-cut device of sheet makes step (first hole section) through the oral area at the die, and when the sheet was die-cut system hole, the waste material under the die-cut sinks the card in the die blanking hole of small-size (second hole section promptly) along with a slice of a slice accumulation of dashing into of drift, just can solve the condition of jumping the waste material.
Drawings
FIG. 1 is a schematic structural view of a sheet punching die of the present invention;
shown in the figure:
1. a female die body; 2. a blanking hole; 21. a first bore section; 22. a second bore section.
Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be noted that the drawings of the present invention are simplified and use non-precise ratios, and are only used for the purpose of facilitating and clearly assisting the description of the embodiments of the present invention.
The utility model provides a die-cut device of sheet, this die-cut device of sheet include terrace die and die, and its drift can be sheared the sheet metal between terrace die and die when the terrace die pushes down to when the drift stretches into the blanking hole on the die, the blanking hole of impressing the waste material that downcuts makes the waste material discharge under the blanking hole.
In order to avoid the problem of scrap jumping, please refer to fig. 1, the female die comprises a female die body 1, a through blanking hole 2 is formed in the female die body 1, the blanking hole 2 is a step hole, the step hole comprises a first hole section 21 connected with the top surface of the female die body 1 and a second hole section 22 with the aperture slightly smaller than that of the first hole section 21, and the second hole section 22 extends to the bottom surface of the female die; wherein the diameter of the first hole section 21 is consistent with the aperture of a hole which is made by punching the sheet material; the height of the first hole section 21 is not less than the thickness of the sheet.
By means of the structure, the step (the first hole section 21) is formed at the opening part of the female die, when the sheet is punched to form the hole, punched waste materials are accumulated and sunk one by one along with the punching of the punch and are clamped in the small-sized female die blanking hole (namely the second hole section 22), the problem of waste material jumping can be solved, and the accumulated waste materials can be gradually extruded and discharged by subsequent waste materials.
The following three specifically preferred dimensions were obtained by testing and are referenced:
when the thickness of the sheet is between 0.1-1mm, the difference between the diameters of the first and second hole sections 21, 22 is 0.02 mm.
When the thickness of the sheet material is between 1-2mm, the difference between the diameters of the first and second hole sections 21, 22 is 0.04 mm.
When the thickness of the sheet material is above 2mm, the difference between the diameters of the first hole section 21 and the second hole section 22 is 0.06 mm.
Various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
