Description

Technical Field

[0001] This utility model relates to the field of building decoration production technology, and in particular to a composite board self-turning and bending system for external corners. Background Technology

[0002] Composite panel external corners refer to the protruding treatment used at the corners of exterior walls. This treatment effectively protects the building's corners from damage and enhances the building's aesthetics. Currently, most composite panel external corner processing is done using a stamping method. The angle of the bending die on the bending machine is typically determined by bending a flat sheet into a panel with an angle. In sheet metal stamping equipment, the angle of the bending die is generally fixed and connected to the overall equipment, making it difficult to change. Therefore, it is impossible to produce panels with different angles, limiting the use of the production equipment. How to improve production efficiency while meeting product manufacturing requirements is also a problem that needs to be solved. Utility Model Content

By setting an upper die, a flip plate, a flip plate support plate, and a support base, it can be used to bend a flat corner board into a corner board with a certain angle. The limiting frame below limits the rotation angle of the flip plate support plate. By changing the limiting frame, corner boards with different angles can be bent. In addition, the longitudinal length of the upper die, flip plate, flip plate support plate, and support base is several times the longitudinal length of the flip plate, which can realize the simultaneous bending of multiple corner boards.

The system includes an upper die 1, a flip plate 3, a flip plate support plate 4, a support base 5, and a limiting frame 16.

[0043] The corner panel 2 includes a left corner panel 9 and a right corner panel 10; the left corner panel 9 and the right corner panel 10 are connected; a bend 7 is formed between the left corner panel 9 and the right corner panel 10.

[0044] The system also includes an upper blade clamp 11 and an upper gate 12; the upper blade clamp 11 is connected to the upper blade die 1; the upper blade clamp 11 is connected to the upper gate 12.

[0045] The upper gate 12 is connected to the main body of the bending machine. The main body of the bending machine can be an existing commercially available bending machine. The upper gate 12 is an existing commercially available upper gate of the bending machine. This application does not improve the main structure of the bending machine.

[0046] Two upper blade clamps 11 are respectively disposed on both sides of the upper gate plate 12. The upper sides of the two upper blade clamps 11 are connected to the upper gate plate 12 by fasteners such as bolts. The lower sides of the two upper blade clamps 11 clamp the upper blade mold 1. The upper blade mold 1 has a positioning protrusion. The upper end of the positioning protrusion abuts against the lowest side of one upper blade clamp 11 to position the upper blade mold 1 connected to the upper blade clamp 11.

[0047] The system also includes a worktable 13; the support base 5 is connected to the worktable 13.

[0048] The flip plate 4 includes a left plate 14 and a right plate 15; the left plate 14 and the right plate 15 are respectively connected to the support base 5.

[0049] The flap 3 includes a left flap and a right flap. The left flap is connected to the left support plate 14, and the right flap is connected to the right support plate 15.

[0050] Two flap support rods 6 are connected to the left support plate 14 and the right support plate 15 respectively. The connection between the flap support rod 6 and the left support plate 14 is off-center from the center of gravity of the left support plate 14, and the direction of the offset is closer to the right support plate 15. The connection between the flap support rod 6 and the right support plate 15 is off-center from the center of gravity of the right support plate 15, and the direction of the offset is closer to the left support plate 14.

[0051] The support base 5 is provided with a limiting frame 16, which is located in the middle and below between the left support plate 14 and the right support plate 15.

[0052] like Figure 6 As shown, the top of the limiting frame 16 is M-shaped, with the two sides used to match and limit the bending with the left support plate 14 and the right support plate, and the middle used to match and limit the bending of the corner plate 2.

[0053] When the flip plate 4 is horizontal, it is limited below by the two sides of the main body of the support seat 5.

[0054] The main body of the support base 5 includes two opposite sides and two end faces connected to the two sides, and the flap support rod 6 passes through the two end faces of the main body of the support base 5.

[0055] The centers of the upper die 1, corner plate 2, flip plate 3, flip plate support plate 4, and support base 5 are on the same vertical straight line. The center of the flip plate support plate 4 is the midpoint between the left support plate 14 and the right support plate 15.

[0056] The longitudinal length of the upper die 1, the flip plate 3, the flip plate support plate 4, and the support seat 5 is greater than the longitudinal length of the corner plate 2.

[0057] The longitudinal length of the upper die 1, flip plate 3, flip plate support plate 4, and support base 5 is several times the longitudinal length of the corner plate 2. More preferably, the longitudinal length of the upper die 1, flip plate 3, flip plate support plate 4, and support base 5 is 2 to 8 times the longitudinal length of the corner plate 2. For example, the longitudinal length of the corner plate 2 is 1264 mm, the longitudinal lengths of the upper die 1, flip plate 3, flip plate support plate 4, and support base 5 are all greater than 3500 mm, and the longitudinal length of the worktable 13 is 4000 mm.

[0058] The working method of the above-mentioned composite panel external corner self-reversing bending system includes:

[0059] Flip plate 4 and flip plate 3 are in a horizontal state (e.g.) Figure 4 As shown), place the corner panel 2 flat on the flip plate 3. Multiple corner panels 2 can be placed on the flip plate 3 in sequence so that multiple corner panels 2 can be bent at the same time.

[0060] The upper die 1 descends, contacts the bending opening 7 and continues to descend, while the flip plate 3 and flip plate support 4 tilt (e.g.) Figure 5 As shown), the lower part is limited by the tilt angle of the limiting frame 16, which causes the corner plate 2 to bend.

[0061] The lower limiting frame 16 limits the extreme flipping angle of the flip plate 3 and the flip plate support plate 4, and also limits the lower end of the bent corner plate 2.

[0062] After bending, the upper die 1 rises and removes the corner plate 2. Because the connection position of the flip plate support rod 6 is off-center, the flip plate support plate 4 returns to a horizontal state under the action of gravity.

[0063] The embodiments described herein are provided to enable those skilled in the art to understand and use this invention. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, this invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of this invention without departing from its scope should be within the protection scope of this invention.
