[0001] This utility model relates to the field of aluminum alloy profile processing technology, and more specifically, to a device for punching square holes in aluminum alloy profiles. Background Technology
[0002] Aluminum alloy profiles are one of the most widely used non-ferrous metal structural materials in industry, and are extensively used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, construction, decoration, and chemical industries. During processing, aluminum alloys require punching to make the profiles easier to use. I-beam aluminum alloy profiles are particularly widely used; however, existing technologies have the following shortcomings in their application:
[0003] Traditional punching dies for I-shaped aluminum alloy profiles typically involve placing the workpiece on top for punching before milling it on a milling machine. This significantly impacts actual processing efficiency and is not practical for real-world use.
[0004] Therefore, there is an urgent need for a device for punching square holes in aluminum alloy profiles to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the problem that in the current practice of some punching dies, the workpiece is placed on top for punching on I-shaped aluminum alloy profiles, and then milled on a milling machine, which greatly affects the actual processing efficiency and is not conducive to practical use.
[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The application is as follows:
[0009] A device for punching square holes in aluminum alloy profiles includes a base, an upper die positioned directly above the base, a mounting seat mounted on the top of the base, a limiting seat mounted on the top of the mounting seat, a limiting plate fixedly mounted on the upper die, an opening provided on the limiting plate, an I-shaped aluminum alloy profile placed within the opening, six spring cylinders vertically fixedly connected to the base, four guide posts fixedly mounted on the top of the base for guiding the upper die, and a punch fixedly mounted on the lower surface of the limiting plate.

[0015] As a preferred technical solution of this application, the placement opening is rectangular, and one side surface of the I-shaped aluminum alloy profile is in contact with the inner surface of one side of the placement opening.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] Example:
[0027] like Figure 1-3 As shown, this embodiment proposes a device for punching square holes in aluminum alloy profiles, including a base 1. An upper die 2 is disposed directly above the base 1. The base 1 is installed in a designated position by bolts, so that the upper die 2 is located directly below the stamping equipment. A mounting seat 3 is installed on the top of the base 1, and a limiting seat 4 is installed on the top of the mounting seat 3. A limiting plate 5 is fixedly installed on the upper die 2, and a placement opening 6 is opened on the limiting plate 5. An I-shaped aluminum alloy profile 7 is placed in the placement opening 6. Six spring cylinders 8 are vertically fixedly connected to the base 1, and the upper ends of the six spring cylinders 8 are all fixedly connected to the upper die 2. The top of the base 1 is fixedly mounted with a mounting seat 3. The upper mold 2 is equipped with four guide pillars 9 for guiding the upper mold 2. The upper ends of the guide pillars 9 are located inside the upper mold 2. A punch 11 is fixedly installed on the lower surface of the limiting plate 5. The punch 11 is T-shaped. The upper mold 2 is driven to move downward by the external stamping equipment. The limiting plate 5 and the punch 11 move downward synchronously with the upper mold 2. The four guide pillars 9 can guide the upper mold 2, the limiting plate 5 and the punch 11. The downward T-shaped punch 11 can perform punching processing on the I-shaped aluminum alloy profile 7. The specific shape of the punching is a T-shaped opening. The I-shaped aluminum alloy profile 7 can be punched in one go.
[0028] like Figure 1 and Figure 3 As shown, the limiting plate 5 is divided into two by the placement opening 6. The opening width of the placement opening 6 is greater than the width of the middle part of the I-shaped aluminum alloy profile 7. The placement opening 6 facilitates the placement and removal of the I-shaped aluminum alloy profile 7.
[0029] like Figure 1As shown, the upper end of one side of the limiting seat 4 is trapezoidal, the outer surface of the limiting seat 4 is in contact with the outer surface of the I-shaped aluminum alloy profile 7, the placement opening 6 is rectangular, and one side surface of the I-shaped aluminum alloy profile 7 is in contact with the inner surface of one side of the placement opening 6. By the cooperation of the limiting seat 4 and the placement opening 6, the I-shaped aluminum alloy profile 7 can be laterally limited, which facilitates the subsequent punching process of the I-shaped aluminum alloy profile 7.
[0030] Working principle: The base 1 is installed in the designated position with bolts, so that the upper die 2 is directly below the stamping equipment. The I-shaped aluminum alloy profile 7 is inserted into the placement opening 6, so that one side surface of the I-shaped aluminum alloy profile 7 is in contact with the inner side surface of the placement opening 6. The outer surface of the limiting seat 4 is in contact with the outer surface of the I-shaped aluminum alloy profile 7, thus limiting the I-shaped aluminum alloy profile 7 laterally. When the position of the I-shaped aluminum alloy profile 7 to be punched is directly below the punch 11, the upper die 2 is moved downward by the external stamping equipment. The limiting plate 5 and the punch 11 move downward synchronously with the upper die 2. The four guide pillars 9 can guide the upper die 2, the limiting plate 5, and the punch 11. The T-shaped punch 11 can perform punching processing on the I-shaped aluminum alloy profile 7. The specific punching shape is a T-shaped opening, which can complete the punching of the I-shaped aluminum alloy profile 7 in one go. At the same time, after punching, it is not necessary to place the I-shaped aluminum alloy profile 7 on a milling machine for milling. By changing the traditional installation position of the punch 11, the punching efficiency of the I-shaped aluminum alloy profile 7 can be greatly improved, which is beneficial to actual production processing. When the outer stamping equipment disengages from the upper die 2, the elastic force of the six spring cylinders 8 can drive the upper die 2, the limiting plate 5 and the punch 11 to move upward and reset, so that the punched I-shaped aluminum alloy profile 7 can be taken out from the placement opening 6.
[0031] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
