Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or reference letters in the various examples, which have been repeated for purposes of simplicity and clarity and do not in themselves dictate a relationship between the various embodiments and/or arrangements discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

For convenience of description, in the present application, front refers to a side facing an operator in work, i.e., a right side in fig. 1; the rear is opposite the front, i.e. to the left in fig. 1.

Referring to fig. 1-2, the stamping die for aluminum profiles provided by the present invention comprises a lower template 1, an upper template 2 and at least two guide posts 3, wherein the upper template 2 is slidably connected with the guide posts 3 and can move up and down; the middle template 4 is arranged between the upper template 2 and the lower template 1, and the middle template 4 is in sliding connection with the guide column 3;

the front side of the middle template 4 is provided with a positioning part 401 matched with the inner groove 4 '(see fig. 3) of the aluminum profile 90 to be processed, and the positioning part 401 is used for the inner groove 4' of the aluminum profile 90 to be processed to be sleeved; punch insertion holes 402 are formed in the upper and lower sides of the positioning portion 401; an accommodating cavity 403 is formed in the middle die plate 4, and the punch inserting hole 402 is communicated with the accommodating cavity 403;

an upper pressing seat 5 is arranged on the lower side of the upper template 2, and an upper punch 501 is arranged at the position of the upper pressing seat 5, which is opposite to the punch inserting hole 402 on the upper side of the positioning part 401;

a lower press base 6 is provided on the upper side of the lower die plate 1, and a lower punch 601 is provided on the lower press base 6 at a position facing the punch insertion hole 402 on the lower side of the positioning portion 401.

When the stamping die for the aluminum profile is used, an inner groove 4' of an aluminum profile 90 (which is a U-shaped groove aluminum profile) to be processed is sleeved into a positioning part 401 of a middle template 4 (as shown in fig. 1), then an upper template 2 is pressed downwards (generally pressed downwards under the driving force of a hydraulic cylinder), the middle template 4 is pushed to move downwards, finally an upper punch 501 and a lower punch 601 simultaneously punch two wing plates of the aluminum profile, and punched aluminum scraps are pressed into an accommodating cavity 403 in the middle template 4 from a punch stretching hole 402 so as to avoid blocking the punch stretching hole 402; therefore, the long waist holes of the two wing plates of the U-shaped groove aluminum profile can be processed by one-step stamping, and the production efficiency is high.

Further, referring to fig. 1, in order to facilitate cleaning of aluminum scraps in the accommodating chamber 403, a discharge opening 404 is provided at the bottom of the middle mold plate 4, and the discharge opening 404 is communicated with the accommodating chamber 403.

In some preferred embodiments, see fig. 1, the bottom of the receiving chamber 403 is inclined, and the discharge opening 404 communicates with the lowest part of the receiving chamber 403. Therefore, the aluminum scraps falling into the accommodating cavity 403 can automatically slide to the discharge port 404 under the action of gravity and be discharged, the accommodating cavity 403 does not need to be cleaned manually, and the use is more convenient.

Further, as shown in fig. 2, two ends of the positioning portion 401 are provided with a limiting protrusion 405, and the limiting protrusion 405 is used for axially positioning the aluminum profile 90 to be processed. After the aluminum profile 90 to be processed is sleeved into the positioning portion 401, the two limiting protrusions 405 abut against the two ends of the aluminum profile 90 to be processed, so that the axial positioning is realized.

In some preferred embodiments, see fig. 2, the back side of the positioning part 401 is provided with a space avoiding groove 406 for inserting fingers to push out the aluminum profile. Because a certain friction force exists between the processed aluminum profile and the positioning portion 401, it is difficult for a worker to draw out the processed aluminum profile, and at this time, a finger can be inserted into the avoiding groove 406 to apply force, so that the processed aluminum profile is convenient to take out.

Further, as shown in fig. 1, the guide posts 3 are sleeved with first compression springs 7, and the first compression springs 7 are arranged between the lower die plate 1 and the middle die plate 4. After the one-time stamping work is finished, the upper die plate 2 can move upwards to reset under the action of the hydraulic cylinder, and at the moment, the middle die plate 4 can automatically move upwards to reset under the action of the first compression spring 7, so that an operator can take out the processed aluminum profile and put in the aluminum profile to be processed.

Further, as shown in fig. 1, a second compression spring 8 is sleeved on the guide post 3, and the second compression spring 8 is arranged between the upper die plate 2 and the middle die plate 4. The second compression spring 8 can prevent the middle template 4 from impacting the upper pressing seat 5 due to upward impact when being reset.

In some embodiments, the middle formwork 4 and the upper formwork 2 are both provided with sliding sleeves 9, and are slidably connected with the guide posts 3 through the sliding sleeves 9, so as to improve the positioning accuracy.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-mentioned preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and the embodiments are substantially the same as the present invention.
