[0033] 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0034] As Figures 1 to 6As shown in the figure, a lamp board frame forming device includes a material feeding rack 2 and a machine frame 3. The machine frame 3 is successively provided with a traction device 4, a folding device 5 and a cutting device 6. The traction device 4 is used to traction the metal strip on the material feeding rack 2 into the folding device 5; the folding device 5 is used to fold the metal strip into a preset shape. The folding device 5 includes a number of folding roller groups 51 arranged in sequence. The number of folding roller groups 51 gradually folds the metal strip into a preset shape; the cutting device 6 is used to cut the folded metal strip into a border with a predetermined length.
[0035] In this application, the metal strip raw material is placed on the material feeding rack 2. After the device is started, the traction device 4 starts to work. It contacts the metal strip through the traction structure and applies a pulling force, gradually pulling the metal strip out of the material feeding rack 2 and moving it towards the folding device 5.
[0036] After the metal strip enters the folding device 5, it will successively pass through a number of arranged folding roller groups 51. Each folding roller group 51 is designed with a specific contour and relative position. When the metal strip passes through the first folding roller group 51, under the extrusion and guiding action of the roller group, the metal strip begins to undergo preliminary bending deformation. As the metal strip continues to move forward, the subsequent folding roller groups 51 will, according to the preset shape requirements, these folding roller groups 51 work together. Each group further precisely adjusts the shape of the metal strip on the basis of the bending of the previous group, and finally folds the metal strip into a preset shape.
[0037] The metal strip processed into a preset shape by the folding device 5 will continue to move forward to the cutting device 6. The cutting device 6 usually uses a cutter or other cutting tools. When the metal strip moves to a predetermined length, the cutting device 6 will act quickly to cut the metal strip into a border of the corresponding length, completing the forming process of a single component of the lamp board frame.
[0038] Compared with the traditional method of making a frame by integral forming or cutting and splicing of aluminum profiles, this device uses a metal strip as the raw material. The cost of the metal strip is relatively low, and through the automated folding and cutting process, a large amount of labor processing costs are reduced, effectively reducing the overall cost. In this application, the folding roller group 51 has 27 groups. As Figures 6 - 7 shown, each folding roller group 51 includes two corresponding extrusion rollers, and each folding roller group 51 is different. The specific shape is not described in detail here. It can be designed and arranged according to requirements. Figures 5 - 7 In the figure shows the folding process of 27 folding roller groups 51, and the metal strip shown in a in Figure 5 can be folded into the border cross-sectional view shown in b.
[0039] Specifically, the traction device 4 includes a traction roller set 41 and a traction frame 42. The traction frame 42 is fixed on the frame 3. A guide groove 421 is provided on the traction frame 42. Guide sliding grooves 4211 are formed on both side walls of the guide groove 421, and the bottom wall of the guide groove 421 is connected to the lower wall of the guide sliding groove 4211. The traction roller set 41 is arranged between the feeding rack 2 and the traction frame 42. The traction roller set 41 includes a first roller 411 and a second roller 412. The first roller 411 and the second roller 412 form a gap and are aligned with the guide sliding groove 4211.
[0040] Before the device starts, the metal strip is led out from the feeding rack 2, and its end is placed at the gap formed by the first roller 411 and the second roller 412. Since the first roller 411 and the second roller 412 are aligned with the guide sliding groove 4211, the metal strip is initially positioned when entering the traction device 4, ensuring that it can accurately enter the subsequent guide groove 421 structure.
[0041] Specifically, the first roller 411 and the second roller 412 are rubber rollers.
[0042] During the production process of the metal strip, the surface quality is crucial. The rubber rollers are relatively soft in texture. When contacting the metal strip and applying traction force, they can effectively avoid damaging the surface of the metal strip, such as scratching and abrasion.
[0043] Preferably, it further includes an electric control box, several motors, and a touch screen. The electric control box and the motors are embedded at the bottom of the frame 3, and the touch screen is arranged on the side of the frame 3. Both the motors and the touch screen are electrically connected to the electric control box.
[0044] Through the touch screen, the operator can centrally control the entire lamp board enclosure forming device. There is no need to adjust different functional components separately at various parts of the equipment. On only one operation interface, key operating parameters such as the speed of the traction device 4, the folding parameters of the folding device 5, and the cutting length of the cutting device 6 can be easily set, greatly improving the operation efficiency and reducing the possibility of operation errors.
[0045] Furthermore, it further includes several speed reducers. The speed reducer has an input shaft, a first output shaft, and a second output shaft. The input shaft and the first output shaft are coaxially arranged, and the first output shaft and the second output shaft are perpendicularly arranged. The several speed reducers are sequentially connected in the order of the input shaft and the first output shaft, and the second output shaft is correspondingly connected to the traction roller set 41 to drive the traction roller set 41 to operate. The output shaft of one of the motors is connected to the output shaft of the speed reducer. These technologies are prior arts and will not be elaborated in detail here and can be adjusted according to actual situations.
[0046] Specifically, the cutting device 6 includes a moving frame 61, a cutting knife 62, a first driving member 63, and a second driving member 64. The moving frame 61 is slidably disposed on the machine frame 3. The first driving member 63 is installed on the machine frame 3. The first driving member 63 is connected to the moving frame 61 and can move back and forth along the conveying direction of the metal strip. The second driving member 64 is fixed on the moving frame 61. The cutting knife 62 is installed on the second driving member 64. The second driving member 64 drives the cutting knife 62 to move and cut the metal strip. The cutting knife 62 is arranged to move and cut from one side of the metal strip, and the moving direction of the cutting knife 62 forms a 45° angle with the moving direction of the metal strip.
[0047] After the metal strip is pulled and folded into a preset shape, it continues to move in the direction of the cutting device 6. At this time, the initial position of the moving frame 61 is on one side of the machine frame 3, the first driving member 63 is in a standby state, and the cutting knife 62 is in the initial position under the action of the second driving member 64, ready to cut the upcoming metal strip. When the metal strip moves to the predetermined cutting length position, the first driving member 63 is activated. It pushes the moving frame 61 along the preset slide rail on the machine frame 3 in the conveying direction of the metal strip. Through this movement, the cutting knife 62 installed on the moving frame 61 can accurately align with the part of the metal strip that needs to be cut, completing the lateral positioning. The second driving member 64 drives the cutting knife 62 to move from one side of the metal strip at an angle of 45° with the moving direction of the metal strip. Due to this specific angle, when the cutting knife 62 contacts the metal strip, it will gradually cut into the metal strip in a bevel cutting manner. As the cutting knife 62 continues to move, the metal strip is finally cut off, completing one cutting operation, and each subsequent border can be directly connected together.
[0048] The moving direction of the cutting knife 62 forms a 45° angle with the moving direction of the metal strip, which can form a right angle when two borders are assembled.
[0049] In this application, when the moving frame 61 moves along the conveying direction of the metal strip, the moving speed of the moving frame 61 is consistent with the moving speed of the metal strip.
[0050] Specifically, the cutting device 6 further includes a fixing frame 65, a third driving member 66, a first limiting block 67, and a second limiting block 68. The fixing frame 65 is fixed on the moving frame 61. The third driving member 66 is installed on the fixing frame 65. The first limiting block 67 is fixed on the moving frame 61, and the first limiting block 67 is provided with a limiting groove 671 and a knife groove 672. The knife groove 672 penetrates the limiting groove 671. The second limiting block 68 is connected to the third driving member 66. The second limiting block 68 can abut against the first limiting block 67 and cover the limiting groove 671 and the knife groove 672. The cutting knife 62 is slidably disposed in the knife groove 672, and the limiting groove 671 is arranged along the conveying direction of the metal strip.
[0051] The first limit block 67 constructs a very precise guiding and limiting system for the cutting knife 62 by virtue of the limit groove 671 and the knife groove 672, which can ensure that the cutting knife 62 always cuts into the metal strip accurately along the predetermined 45° included angle direction.
[0052] When the first limit block 67 and the second limit block 68 are in contact, the metal strip can be pressed, so that the cut is more stable and flat during cutting. When the moving frame 61 moves in the direction opposite to the conveying direction of the metal strip, the first limit block 67 and the second limit block 68 are separated, so that the metal strip can move in the limit groove 671.
[0053] Specifically, the first driving member 63, the second driving member 64, and the third driving member 66 adopt air cylinders or oil cylinders.
[0054] Specifically, an inclined guide plate 69 is fixed on the moving frame 61, and the guide plate 69 is arranged at the rear side of the cutting knife 62.
[0055] The guide plate 69 is inclined and arranged at the rear side of the cutting knife 62. When the cutting knife 62 completes the cutting action on the metal strip, the cut-off frame will slide down along the inclined surface of the guide plate 69 under its own gravity and the inertia generated during cutting. The specific value of the inclination angle of the guide plate is 30° - 60°.
[0056] Such as Figures 5 to 7 shown in a lamp board frame forming process, which includes the following steps:
[0057] Set the metal strip on the feeding rack 2;
[0058] Feed the metal strip into the folding device 5 through the traction device 4;
[0059] Continuously and gradually fold the frame metal strip through the folding device 5 until it is folded into a preset shape;
[0060] After folding, the metal strip enters the cutting device 6 to cut a border structure of a preset length;
[0061] Combine and weld the four border structures to form a frame. The specific welding method can adopt laser welding.
[0062] It should be noted that all the directional indications in the embodiments of the present invention, such as up, down, left, right, front, back..., are only used to explain the relative position relationship and movement conditions between the components in a specific posture, as shown in the drawings. If this specific posture changes, then the directional indication also changes accordingly.
