Description

Technical Field

[0001] The present invention relates to the field of aluminum profiles, and in particular to a punching device for aluminum profiles of a sunroom. Background Art

[0002] The existing punching dies for sunrooms can only punch the dimensions at a single position with a certain part as the reference. Figure 1 and Figure 2 As shown, the installation angle of the profile 1' is adjusted by the connecting piece 2', and the screws 3' and the screw holes 4' are perpendicular to the surface of the profile 1'.

[0003] Due to the differences in the shape and size of the sunroom, the end face angle and the punching position of the profile will change. The existing punching die solutions are difficult to meet the punching requirements of multi-variety and small-batch sunroom profiles; moreover, for the conventional punching die, when positioning the profile with a non-90-degree end face, the positioning block and the profile are in line contact. During punching, the profile is prone to displacement, resulting in poor punching accuracy, which is not conducive to on-site construction and also has an adverse impact on the die life. Summary of the Invention

[0004] The present invention provides a punching device for aluminum profiles of a sunroom, which solves the technical problem of low punching accuracy of profiles with non-90° end faces in the prior art.

[0005] The technical solution of the present invention is realized as follows:

[0006] A punching device for aluminum profiles of a sunroom includes a bottom die. A profile positioning block is provided on the top of the bottom die. A positioning hole corresponding to the punch is provided on the profile positioning block. A strip-shaped mounting hole is provided on the profile positioning block. A swing positioning block is provided in the mounting hole. The middle part of the swing positioning block is rotatably mounted in the mounting hole through a rotating shaft. The two ends of the swing positioning block respectively extend upward and downward out of the mounting hole. The swing positioning block includes a positioning surface in contact with the profile end face. The swing positioning block rotates through the rotating shaft to adjust the included angle of the positioning surface to fit the profile end face.

[0007] As a preferred technical solution, an outwardly extending support arm is provided in the middle part of the swing positioning block, and a bushing is provided at the end of the support arm. The bushing is sleeved on the rotating shaft.

[0008] As a preferred technical solution, the swing positioning block includes an upper positioning part extending upward and in contact with the upper part of the profile end face, and a lower positioning part extending downward and in contact with the middle and lower parts of the profile end face.

[0009] As a preferred technical solution, the width of the lower positioning part is greater than the width of the profile end face, and the two ends of the lower positioning part are respectively in contact with the two side edges of the profile end face.

[0010] As a preferred technical solution, the rotating shaft is located at the front end of the mounting hole, and an adjustment area for facilitating the rotation of the swing positioning block is formed between the rear end of the mounting hole and the rotating shaft.

[0011] The beneficial effects of the present invention are as follows: A swing positioning block is provided on the profile positioning block of the present invention for positioning the end face of the profile. Through the positioning of the profile end face, when punching holes on the profile surface, the profile is not easily displaced, the punching position is accurate, and the punching accuracy of the non-90° end face profile surface is improved.

[0012] Since a mounting hole is provided on the profile positioning block, the swing positioning block is rotatably mounted in the mounting hole, and the swing positioning block adjusts its inclination angle by rotation so that it can fit the angle of the profile end face, ensuring the accuracy and stability of the profile fixation.

Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0021] As Figure 3 and Figure 4 shown, a punching device for aluminum profiles of a sunroom includes a bottom die 2. A profile positioning block 4 is provided on the top of the bottom die 2. A positioning hole 41 corresponding to a punch needle 3 is provided on the profile positioning block 4. A strip-shaped mounting hole 42 is provided on the profile positioning block 4. A swing positioning block 6 is provided in the mounting hole 42. The middle part of the swing positioning block 6 is rotatably mounted in the mounting hole 42 through a rotating shaft 5. The two ends of the swing positioning block 6 respectively extend upward and downward out of the mounting hole 42.

[0022] The swing positioning block 6 includes a positioning surface 61 that contacts the end surface of the profile. The swing positioning block 6 rotates through the rotating shaft 5 to adjust the included angle of the positioning surface 61 to fit the end surface of the profile 1.

[0023] An outwardly extending support arm 62 is provided in the middle part of the swing positioning block 6. A bushing 63 is provided at the end of the support arm 62. The bushing 63 is sleeved on the rotating shaft 5.

[0024] The swing positioning block 6 includes an upper positioning part 64 that extends upward and contacts the upper part of the end surface of the profile 1, and a lower positioning part 65 that extends downward and contacts the middle and lower parts of the end surface of the profile 1.

[0025] The width of the lower positioning portion 65 is greater than the width of the end face of the profile. Both ends of the lower positioning portion 65 are in contact with the two side edges of the end face of the profile.

[0026] To ensure the rotation of the swing positioning block 6, the rotating shaft 5 is located at the front end of the mounting hole 42, and an adjustment area facilitating the rotation of the swing positioning block 6 is formed between the rear end of the mounting hole 42 and the rotating shaft 5.

[0027] During punching, the profile positioning block 4 penetrates into the cavity of the profile 1. The surface of the profile 1 is attached to the surface of the profile positioning block 4. The end face of the profile 1 extends forward to contact the swing positioning block 6. By rotating the rotating shaft 5 to adjust the inclination angle of the swing positioning block 6, the positioning surface 61 of the swing positioning block 6 is docked with the end face of the profile 1 to limit the position of the profile. After the position of the profile 1 is fixed, the stamping device is started, and holes are punched on the surface of the profile 1 through the punch pin 3.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
