Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die. Background Art

[0002] Sheet metal stamping dies are tools used to process metal sheets into required parts with certain contour shapes and sizes during the stamping process, and are widely used in different industries.

[0003] At present, when stamping metal sheets, the stamping die basically presses down the stamping knife installed on the upper die quickly and then stamps the metal sheet placed on the lower die. This method allows the stamping knife to reset when no stamping is performed. After the reset, the stamping knife is separated from the lower die and is in a suspended state. After the metal sheet is replaced, the next round of stamping will continue. In this case, the direction of stamping is completely determined by the position of the stamping knife fixed on the upper die. However, since the stamping knife is separated from the lower die, the stamping knife will inevitably shift in position after being used for a long time. If the stamping knife is not guided to move, the stamping knife will easily deviate from the originally set stamping position. In addition, after the metal sheet is placed, the hole for inserting the metal sheet cannot quickly locate the position of the metal sheet, which affects the efficiency of stamping. Utility Model Content

[0004] In order to overcome the deficiencies of the existing technical solutions, the utility model provides a stamping die, which can effectively solve the technical problems of the current stamping die being easy to deviate during stamping and being difficult to position.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, the utility model provides a stamping die, which is mainly used for stamping and forming metal sheets. Its specific structure mainly includes a stamping upper die 1 and a stamping lower die 2. The stamping upper die 1 is connected to one end of the stamping lower die 2 through a stamping guide rod assembly 3, so that the stamping upper die 1 moves along the stamping guide rod assembly 3 toward one end of the stamping lower die 2 to achieve stamping. The stamping upper film 1 and the stamping lower die 2 are used in combination, and the stamping upper die 1 quickly stamps toward one end of the stamping lower die 2 to finally form the metal sheet.

[0023] The stamping guide rod assembly 3, which connects the upper stamping die 1 and one end of the lower stamping die 2, consists of a guide post 301 and a guide sleeve 302. The guide sleeve 302 is mounted on the bottom of the upper stamping die 1, while the guide post 301 is mounted on the top of the lower stamping die 2 and is inserted into the guide sleeve 302 for movement. It should be noted that during stamping, the guide post 301 and the guide sleeve 302 are not separated to ensure that the stamping position does not shift.

[0024] The bottom of the upper die 1 is equipped with a punching knife 4 for punching toward the top of the lower die 2. The punching knife 4 is fixed by a knife holder 10. A detachable structure is formed between the knife holder and the upper die 1, which facilitates the maintenance or replacement of the punching knife 4. In order to enable the punching knife 4 to move and punch quickly, a punching connection part 11 for connecting to a drive motor is added to the top of the upper die 1.

[0025] Correspondingly, a stamping base 5 for use with a stamping knife 4 is installed on the top of the stamping lower die 2. In this technical solution, the stamping knife 4 is reset before or after stamping, and is inserted into the inside of the stamping base 5 and does not detach. An inlet 6 with conductive two sides is set inside the stamping base 5. The inlet 6 is mainly used for users to put metal sheets to be stamped. Since both ends of the inlet 6 are conductive, the metal sheet put in can be operated in and out during stamping. In addition, it is also possible to put in and take out through one end of the inlet 6. Therefore, a positioning column 7 for positioning is set at the end of the inlet 6 away from the metal sheet. After the metal sheet contacts the positioning column, a positioning structure is formed.

[0026] There are three positioning posts 7, which form a detachable structure with the stamping base 5 and can be installed and used when needed. When assembled, the positioning posts 7 are inserted from the top of the stamping base 5, passed through the insertion port 6, and then locked in place. Correspondingly, the stamping base 5 is provided with several rows of positioning holes 13 with different positioning distances. The positioning posts 7 can be assembled in the positioning holes 13 by rotating and then locking.

[0027] In order to better punch, the top of the stamping base 5 is connected to the inside of the inlet 6 to form a first stamping hole 8, and the inside of the inlet 6 is connected to the inside of the stamping lower die 2 to form a second stamping hole 9. The contours of the first stamping hole 8 and the second stamping hole 9 are the same as the external contour of the stamping knife 4, and the positions of the first stamping hole 8 and the second stamping hole 9 are aligned in a straight line. The assembled stamping knife 4 is set in the first stamping hole 8 and does not detach regardless of whether it is in the state of stamping processing. During stamping, the stamping knife 4 punches the metal sheet placed in the inlet 6 along the first stamping hole 8. After the metal sheet is punched off, it falls along the second stamping hole 9 and is also guided by the first stamping hole 8. The stamping knife 4 is better aligned with the second stamping hole 9 to avoid stamping deviation or the inability of the stamped metal sheet to fall from the second stamping hole 9.

[0028] In order to better discharge the metal sheets that fall into the second punching hole 9 after punching, a blanking trough 12 connected to the second punching hole 9 is provided inside the stamping lower die 2. The blanking trough 12 extends away from one end of the second punching hole 9 to the outside of the stamping lower die 2 and is connected. The internal blanking trough 12 forms a slope with a certain inclination, which is used to better discharge the fallen metal sheets.

[0029] Compared with traditional technology, the stamping die provided by this technical solution has the stamping knife 4 arranged in the first stamping hole 8 of the stamping base 5 before and after stamping, and does not detach, to prevent the stamping position from deviating when the stamping knife 4 is suspended in the air and then stamped, causing the second stamping hole 9 to be blocked and affecting the blanking. In addition, by installing the positioning column 7 at different positions of the stamping base 5, different stamping positioning distances can be formed, and the position of the metal sheet can be quickly positioned before stamping.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference numerals in the claims should not be construed as limiting the claims to which they relate.
