Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy photo frames, and particularly relates to an aluminum alloy photo frame formed by seamless welding and integrally formed. Background Art

[0002] At present, traditional photo frames can be made of materials such as plastic, wood, metal or aluminum alloy. In the existing photo frame production technology, aluminum alloy photo frames are widely popular due to their advantages such as light weight, corrosion resistance and beauty, and are widely used in the photo frame manufacturing field. However, the structures of traditional photo frames are all formed by split splicing methods, etc. to form a fixed installation. Basically, four separate frame strips are used and fixed installations are formed at the corner positions of the frame strips, such as using glue bonding, screw fixing, etc. at the corner positions to form an integrated photo frame structure. However, in the actual production process, such a photo frame structure has some structural and usage problems, specifically as follows: (1) The installation of the photo frame is relatively troublesome. After the production of each component is completed, it is necessary to align each frame strip to form a pre-positioned splicing, and then use bonding or fixing components to fix the two frame strips. During the fixing process, it is necessary to ensure that the edges of each frame are set at 90 degrees; in this way, it will cause the installation to be complex and troublesome when forming the integrated structure of the photo frame later. (2) Since four separate frame strips are spliced and installed to form an integrated structure, during installation, it is easy to misplace the frame strips of different lengths, resulting in installation errors, and secondary rework installation is required, with a relatively high installation error rate. (3) After the photo frame is installed and spliced, there are often problems such as obvious splicing gaps, large splicing gaps, sharp burrs at the corners, and the installation heights of the two frame strips at the corners are uneven, etc., causing certain safety hazards and unsightliness in the overall photo frame. Secondary treatment of the corners, etc. is required, with high labor intensity and low production efficiency. In severe cases, the overall quality and grade of the photo frame are low. (4) The structure formed after the photo frame is spliced and installed is prone to deformation or loosening of the photo frame after a long time of use or when the installation is not firm, and the long-term structural strength cannot be guaranteed; it is also prone to deformation or detachment in the case of impacts such as collisions and accidental drops to the ground.

[0003] In addition, in the existing patent technical literature, some integrally formed photo frame structures are also mentioned. For example, in the "A Photo Frame Convenient for Placement" with the patent number 201520959463.0, although the patent mentions that the frame of the photo frame is integrally formed and has a wrapped edge setting, the patent technical solution only mentions that the frame is integrally formed, but does not specifically mention how the integrally formed technical solution is formed; and from the Figure 1 、 Figure 2 and Figure 3It can be seen that there are still gaps at the corners of the frame. In fact, the frame of this patent still adopts the method of splicing and installing the frame strips to form an integrated structure, and it still cannot solve the problems existing in the prior art photo frame structure mentioned above.

[0004] Therefore, it is necessary to make certain improvements to the aluminum alloy photo frame structure of the prior art to improve the problems of the prior art, so as to develop an aluminum alloy photo frame with seamless one-piece molding, stable structure and beautiful appearance. Summary of the invention

[0005] The utility model aims to overcome the disadvantages of the above-mentioned prior art and provide a seamless one-piece aluminum alloy photo frame, which is composed of several large parts such as an integrated square frame, a PS board, a face paper, an inner lining paper, and a back plate; wherein the square frame is formed by bending an integrated whole aluminum alloy strip, and four cutting saw corners are cut on the inner side of the aluminum alloy strip, and the aluminum alloy strip is not cut off when the four cutting saw corners are cut, and the integral continuity of the whole aluminum alloy strip is still maintained; when the aluminum alloy strip is bent and formed by a bending device, the four cutting saw corners are close to each other and spliced ​​to form a tight and small seam, and then the seams at the four corners of the square frame and the seams of the aluminum alloy strip are spot-welded to form a tight connection, so as to achieve a seamlessly connected pile body; in this way, the entire aluminum alloy photo frame is a seamless one-piece structure, has no seams and sharp burrs, is stable in structure, is not easy to deform, and improves the aesthetics and structural strength of the overall photo frame.

[0006] The utility model solves the technical problem by adopting a technical solution: a seamless one-piece aluminum alloy photo frame, comprising an one-piece square frame, and a PS board, an inner lining paper and a backboard which are sequentially embedded and installed from the back of the square frame.

[0007] Furthermore, the square frame is formed by bending an integrated aluminum alloy strip and cutting the inner side of the aluminum alloy strip to form four cutting saw corners. The four right angles formed by the bending of the aluminum alloy strip are formed by bending and splicing the four cutting saw corners in a corresponding manner. The head and tail positions of the aluminum alloy strip after bending and forming and the positions of the four cutting saw corners corresponding to the bending and splicing are connected and fixed by spot welding.

[0008] Furthermore, the angle between the two sides of the cutting saw corner when it is not bent is 90 degrees.

[0009] Furthermore, the four right-angled outer sides of the square frame are arc corners, and the arc corners and the corresponding cutting saw corners are connected and uninterrupted as an integrated structure.

[0010] Further, the four cutting saw notches divide the aluminum alloy strip into five successively connected segments, with the lengths of each segment being 150 mm, 400 mm, 300 mm, 400 mm, and 150 mm in sequence.

[0011] Further, on the inner side wall of the square frame, there are a PS board slot, a lining paper slot, and a back board slot for respectively clamping and installing a PS board, a lining paper, and a back board.

[0012] Further, a hollow square notch is provided in the middle of the lining paper.

[0013] Further, on the back board, there are a back board rotation clamping strip that can be rotatably clamped into the back board slot and a fixed hanging strip that can be hung on the wall.

[0014] To sum up, the seamless integrally formed aluminum alloy photo frame of the present utility model is composed of several major components such as an integrally formed square frame, a PS board, a face paper, a lining paper, and a back board; among them, the square frame is formed by bending a whole aluminum alloy strip, and four cutting saw notches are cut on the inner side of the aluminum alloy strip. When cutting the four cutting saw notches, the aluminum alloy strip will not be cut off, and the whole aluminum alloy strip still remains integrally coherent; when using a bending device to bend the aluminum alloy strip into shape, the four cutting saw notches approach and fit together to form a tight and small seam, and then spot welding treatment is carried out on the seams at the four corners of the square frame and the seams where the head and tail of the aluminum alloy strip are joined together to form a tight connection, thus achieving a seamless connection of the pile body; in this way, the formed whole aluminum alloy photo frame has a seamless integrally formed structure, without joints and burrs, is structurally stable, not easily deformed, and improves the aesthetics and structural strength of the overall photo frame.

[0015] Compared with the photo frames in the prior art, the seamless integrally formed aluminum alloy photo frame has the following advantages:

[0016] 1. Seamless integrally formed: Through precise sawing of corners, bending into shape, and spot welding and other steps, seamless integrally formed of the aluminum alloy photo frame is achieved, improving the aesthetics and structural strength of the aluminum alloy photo frame;

[0017] 2. High production efficiency: By adopting automated production equipment and process flows, the production efficiency and product quality are improved;

[0018] 3. Wide applicability: It is applicable to the production of aluminum alloy photo frames of various specifications and shapes, with wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment 1

[0028] A seamless one-piece aluminum alloy photo frame described in this Embodiment 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, includes an integrally formed square frame 4, and a PS board 3, a lining paper 2, and a back panel 1 that are sequentially embedded and installed from the back of the square frame. When installing a photo, first remove the back panel and the lining paper, then stick the photo tightly on the PS board, and then install the lining board and the back panel back into the square frame in sequence to complete the installation of the entire photo.

[0029] In this Embodiment 1, as Figure 6 shown, the square frame is formed by bending an integrally formed aluminum alloy strip 5 and four cutting saw corner notches 6 are cut on the inner side of the aluminum alloy strip. The four right angles formed by bending the aluminum alloy strip are formed by bending and splicing corresponding to the four cutting saw corner notches respectively; the head and tail positions after bending the aluminum alloy strip and the positions of bending and splicing corresponding to the four cutting saw corner notches respectively are fixed by spot welding.

[0030] The forming process of the square frame includes the following steps:

[0031] (1) Sawing corners: Cut the aluminum alloy material into a preliminary strip shape of an aluminum alloy strip, and perform precise sawing corner treatment on the specified positions of the aluminum alloy strip to form four cutting saw corner notches, ensuring the accuracy and consistency of the angles after sawing corners;

[0032] (2) Bending and forming: Use bending equipment to bend the preliminary-shaped aluminum alloy strip to form a three-dimensional structure of a square frame; during the bending process, strictly control the bending angle and bending radius to ensure the accuracy of forming.

[0033] (4) Spot welding: Perform spot welding connections at the four corners of the square frame after bending and forming and at the head and tail splicing positions of the aluminum alloy strips after bending and forming; adopt appropriate welding parameters and welding equipment to ensure the welding quality and achieve seamless connection at the same time.

[0034] Through the above steps, seamless integral forming of the square frame is achieved, improving the aesthetics and structural strength of the aluminum alloy photo frame.

[0035] In this Embodiment 1, as Figure 7 shown, the included angle between the two sides of the cutting saw corner before bending is 90 degrees. Precisely cutting the cutting saw corner to form a 90-degree included angle can form a 90-degree angle position of the square frame during bending, that is, during bending, the two sides of the cutting saw corner are bent inward by 45 degrees respectively to form a tight fit, achieving a 90-degree angle position of the square frame after bending.

[0036] In this Embodiment 1, the outer sides of the four right angles of the square frame are arc corners, and the arc corners and the corresponding cutting saw corners are an integral structure that is connected and uninterrupted. Since the aluminum alloy strip is not cut off when forming the cutting saw corner, the outer side of the right angle of the square frame formed when the cutting saw corners are bent and close together is still in a connected, seamless and unbroken state, and an arc corner state will be formed on the outer side of this right angle after bending, achieving the effect of no burr.

[0037] In this Embodiment 1, the four cutting saw corners divide the aluminum alloy strip into five successively connected segments, and the length of each segment is 150mm, 400mm, 300m, 400mm, and 150mm in sequence. When the aluminum alloy strip is bent at the four cutting saw corners to form the four corners of the square frame and the head and tail of the aluminum alloy strip are connected and spliced together, the length and width of the formed square frame are 400mm and 300mm.

[0038] In this Embodiment 1, PS board slots 7, inner lining paper slots 8, and back board slots 9 for respectively clamping and installing a PS board, inner lining paper, and back board are provided on the inner side wall of the square frame. The PS board, inner lining paper, and back board are respectively clamped and installed in the corresponding slots to form installation and fixation.

[0039] In this Embodiment 1, a hollow square notch 10 is provided in the middle of the inner lining paper.

[0040] In the present Embodiment 1, a backplane rotation clamping strip 11 that can be rotatably clamped into a backplane card slot and a fixed hanging strip 12 that can be hung on a wall are provided on the backplane. When the backplane is installed in a square frame, the backplane can be fixedly installed in the square frame and removed by rotating the backplane rotation clamping strip, and the entire aluminum alloy photo frame can be fixedly hung on the wall through the fixed hanging strip.

[0041] The seamless integrally formed aluminum alloy photo frame is composed of several major components such as an integrally formed square frame, a PS board, a face paper, a lining paper, and a backplane; among them, the square frame is formed by bending an integrally formed aluminum alloy strip, and four cutting saw corner openings are cut on the inner side of the aluminum alloy strip. When cutting the four cutting saw corner openings, the aluminum alloy strip is not cut off, and the integrity and continuity of the entire aluminum alloy strip are still maintained; when using a bending device to bend the aluminum alloy strip, the four cutting saw corner openings approach and fit together to form a tight and small seam, and then spot welding is performed on the seams at the four corners of the square frame and the seams at the head and tail of the aluminum alloy strip to form a tight connection, thus achieving a seamless connection of the pile body; in this way, the entire formed aluminum alloy photo frame has a seamless integrally formed structure, without seams and burrs, with a stable structure, not easily deformed, and improving the aesthetics and structural strength of the overall photo frame.

[0042] In the present Embodiment 1, compared with the photo frames in the prior art, the seamless integrally formed aluminum alloy photo frame has the following advantages:

[0043] 1. Seamless integrally formed: Through precise sawing of corners, bending forming, and spot welding and other steps, seamless integrally formed of the aluminum alloy photo frame is achieved, improving the aesthetics and structural strength of the aluminum alloy photo frame;

[0044] 2. High production efficiency: Automated production equipment and process flows are adopted, improving production efficiency and product quality;

[0045] 3. Wide applicability: It is applicable to the production of aluminum alloy photo frames of various specifications and shapes, with wide applicability.

[0046] The above is only a preferred embodiment of the present utility model, and does not impose any formal restrictions on the structure of the present utility model. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solutions of the present utility model.
