Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending technology, specifically a self-unloading bending device for sheet metal processing. Background Technology

[0002] Currently, the bending process for sheet metal parts involves placing the sheet metal part on a bending die that matches its final shape. The bending die is mounted on a conveyor belt, which sequentially passes the sheet metal part through a preheating device, a bending device, and an annealing device to achieve the bending process. During bending, as the sheet metal part's temperature gradually increases, its viscosity decreases, causing it to soften. The softened sheet metal part gradually adheres to the bending die, eventually forming a shape that closely matches the die, resulting in a bent sheet metal part. However, as the sheet metal part softens and bends, its central area becomes concave, causing a change in the height of the central area from the heating element. This reduces the heat received in the central area, leading to a less smooth transition in the curved profile. Furthermore, because the conveyor belt requires manual intervention after the annealing device is moved out, the forming glass on the bending die needs to be removed, increasing labor intensity and reducing work efficiency. Therefore, we propose a self-unloading bending device for sheet metal processing. Utility Model Content

[0003] The purpose of this invention is to provide a self-unloading bending device for sheet metal processing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-unloading bending device for sheet metal processing, comprising,

[0005] The basic component includes a base plate, a conveyor belt device is provided on the top of the base plate, and frames are fixed on the top of the base plate and on both sides of the conveyor belt device. A preheating device and an annealing device are respectively provided on the left and right sides between the two sets of frames.

[0006] An adaptive bending assembly includes a housing disposed between two sets of frames, the housing being located between a preheating device and an annealing device, with an inlet and an outlet respectively on both sides of the housing, and symmetrically fixed assembly frames with a vertical cross-section in the shape of a "mountain" on the front and back of the top inner wall of the housing, with a heating device one fixedly disposed at the bottom center between the two sets of assembly frames, and U-shaped frames sliding up and down on both the front and back sides of the two sets of assembly frames, the two sets of U-shaped frames being symmetrically disposed, with a heating device two hinged to the inner wall of each set of U-shaped frames;

[0007] The receiving components are provided in multiple sets, and the multiple sets of receiving components are equidistantly arranged on the top of the conveyor belt device.

[0008] Furthermore, each of the two sets of U-shaped frames has a drum rotatably mounted on one side of the top of each frame via a mounting base and a rotating shaft. A drive gear is coaxially mounted on one side of the drum. A rack is meshed on the side of the drive gear near the center of the assembly frame. The rack is fixed to the outer wall of the bottom center of the front assembly frame. A pull rope is wound around the outer wall of the drum, and the other end of the pull rope movably passes through the U-shaped frame and is connected to the outer end of the top of the second heating device.

[0009] Furthermore, concave seats are symmetrically fixed at the bottom of the inner walls of the front and rear sides of the housing, and guide rods are vertically fixed inside the concave seats. Contact blocks are movably sleeved on the bottom of the outer walls of both sets of guide rods. Connecting springs are sleeved on the outer walls of the guide rods above the contact blocks. One end of a connecting rod is rotatably connected to the front and rear sides of the contact blocks through a pin. The other end of the connecting rods on the front and rear sides is rotatably connected to the top of the front and rear sides of the U-shaped frame through pins, respectively.

[0010] Furthermore, the receiving component includes an assembly base fixed on the conveyor belt device, and a mold body is provided above the assembly base. Contact rods are vertically and movably inserted on the front and rear sides of the top of the mold body, and the bottom of the contact rods movably penetrates the top of the assembly base. A stepped groove adapted to the contact rods is opened on the top of the mold body. An air cylinder is movably sleeved on the outer wall of the contact rods, and the air cylinder is fixed in the assembly base by a T-shaped frame.

[0011] Furthermore, a sealing cylinder is fixedly inserted at the other end of the T-shaped frame, and the bottom of the sealing cylinder and the bottom of the air cylinder on the same side are connected to each other through a U-shaped tube. The contact rod is provided with a matching piston on the outer wall inside the sealing cylinder. A movable rod is movably inserted at the top of the sealing cylinder, and a piston is also provided at one end of the movable rod inside the sealing cylinder. The top of the movable rod movably passes through the top of the mounting base and is fixed to the bottom of the mold body. Protrusions are fixed on both the left and right sides of the mold body, and the protrusions on the left and right sides respectively cooperate with the left and right contact blocks.

[0012] Furthermore, a longitudinal rotating shaft is movably inserted into one side of the mounting base, and a follower gear is fixed at the front end of the rotating shaft.

The L-shaped frame has a notch at one end facing the guide plate, and the inner wall of the notch is connected to a push plate by a telescopic cylinder. A detection device is disposed on the right side of the L-shaped frame facing the guide plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The sheet metal parts of this utility model are bent by the adaptive bending assembly along with the receiving assembly. As the sheet metal parts soften, the contact rod gradually moves downward under its own gravity, thereby gradually pressing the gas in the air cylinder into the sealing cylinder. This causes the moving rod to gradually drive the mold body upward, ensuring that the heat received in the middle area of ​​the sheet metal parts does not change. At the same time, the connecting rod moves the L-shaped frames on both sides upward, directing the heat supply to the bending areas at both ends of the sheet metal parts. This prevents the heat supply on both sides from being too high and makes the curvature transition of the sheet metal parts smoother. After the sheet metal parts are annealed with the receiving assembly, the ejector rod automatically pushes the formed sheet metal parts out of the mold body through the cooperation of the follower gear and toothed plate. Simultaneously, the telescopic cylinder and push plate push the formed sheet metal parts into the guide plate to achieve material pushing, improving work efficiency and greatly reducing manual labor intensity.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-4 This utility model provides a self-unloading bending device for sheet metal processing, comprising: a base assembly 1, which includes a base plate 11, a conveyor belt device 12 mounted on top of the base plate 11, and frames 13 fixed on both sides of the base plate 11 and on the left and right sides between the two sets of frames 13, respectively, a preheating device and an annealing device. The preheating device, annealing device, and conveyor belt device 12 are widely used in the field and will not be described in detail here. The preheating device and annealing device have inlets and outlets on their respective sides; and an adaptive bending assembly 2, which includes a housing 21 disposed between the two sets of frames 13, the housing 21 being located between the preheating device and the annealing device, and inlets and outlets on its respective sides. The top inner wall of the shell 21 is symmetrically fixed with a vertical cross-section in the shape of a "mountain". A heating device 1 is fixedly installed at the bottom center between the two sets of assembly frames 22. U-shaped frames 23 are slidably installed on the front and back sides between the two sets of assembly frames 22. The U-shaped frames 23 are slidably connected by a slider and a vertical groove opened on the assembly frame 22. The two sets of U-shaped frames 23 are symmetrically arranged. A heating device 2 is hinged to the inner wall of the two sets of U-shaped frames 23, so that the heating device 2 can rotate. The heating device 1 and the heating device 2 are selected according to the actual situation, which will not be described in detail here. They are used to heat and bend the glass. There are multiple sets of receiving components 3, and the multiple sets of receiving components 3 are equidistantly arranged on the top of the conveyor belt device 12. The receiving components 3 are used to support the glass to be heated and bent.

[0024] Please see Figure 2 Both sets of U-shaped frames 23 have a drum mounted on one end of each frame via a mounting base and a rotating shaft 39. A drive gear 24 is coaxially mounted on one side of the drum. A rack 25 meshes with the drive gear 24 near the center of the assembly frame 22. The rack 25 is fixed to the outer wall of the bottom center of the front assembly frame 22. A pull rope 26 is wound around the outer wall of the drum. The other end of the pull rope 26 passes through the U-shaped frame 23 and is connected to the outer end of the top of the second heating device. When the connecting rod moves the U-shaped frame 23 upward, the drive gear 24 and the rack 25 engage, thereby causing the drum to wind up the pull rope 26. This causes the second heating device to rotate at a certain angle, ensuring the heat supply to the curved area of ​​the glass end, so that the glass arc contour transition is smoother.

[0025] Please see Figure 2 The bottom of the inner walls of the front and rear sides of the housing 21 are symmetrically fixed with concave seats 27, and guide rods are vertically fixed inside the concave seats 27. Contact blocks 28 are movably sleeved on the bottom of the outer walls of the two sets of guide rods. A connecting spring 29 is sleeved on the outer wall of the guide rod above the contact block 28. One end of the connecting spring 29 is fixed to the top inner wall of the concave seat 27, and the other end is fixed to the bottom of the contact block 28. The front and rear sides of the contact block 28 are rotatably connected to one end of a connecting rod through a pin. The other end of the connecting rod on the front and rear sides is rotatably connected to the top of the front and rear sides of the U-shaped frame 23 through a pin, respectively. When the contact block 28 moves upward, it drives the U-shaped frame 23 upward through the connecting rod.

[0026] Example 2

[0027] Please see Figure 3 The receiving component 3 includes an assembly seat 31 fixed on the conveyor belt device 12. The assembly seat 31, along with the conveyor belt device 12, allows the glass to pass through the preheating device, the adaptive bending assembly 2, and the annealing device for processing. A mold body 32 is provided above the assembly seat 31 for bending the glass into shape. Contact rods 34 are vertically and movably inserted on the front and rear sides of the top of the mold body 32. The bottom of the contact rods 34 movably passes through the top of the assembly seat 31. A stepped groove adapted to the contact rods 34 is opened on the top of the mold body 32. When the contact rods 34 are lowered to the lowest point, their top is on the same arc surface as the top outer wall of the mold body 32. The top of the contact rods 34 blocks the stepped groove. An air cylinder 35 is movably sleeved on the outer wall of the contact rods 34. The air cylinder 35 is fixed in the assembly seat 31 by a T-shaped frame. After the glass is heated to the softening temperature, under its own gravity, it bends downward and presses the contact rods 34 downward, forcing the gas in the air cylinder 35 out.

[0028] Please see Figure 3A sealing cylinder 37 is fixedly inserted at the other end of the T-shaped frame, and the bottom of the sealing cylinder 37 and the bottom of the air cylinder 35 on the same side are connected to each other through a U-shaped tube 36. A matching piston (not shown in the figure) is provided on the outer wall of the contact rod 34 inside the sealing cylinder 37. A movable rod 38 is movably inserted at the top of the sealing cylinder 37, and a piston (not shown in the figure) is also provided at one end of the movable rod 38 inside the sealing cylinder 37. The top of the movable rod 38 movably passes through the top of the mounting base 31 and is fixed to the bottom of the mold body 32. Protrusions 33 are fixed on both the left and right sides of the mold body 32. The right protrusion 33 engages with the left and right contact blocks 28 respectively. The gas in the air cylinder 35 is forced out to the sealing cylinder 37, causing the movable rod 38 to drive the mold body 32 to move upward. When the mold body 32 moves upward, the protrusion 33 causes the contact blocks 28 on both sides to move upward, thereby causing the heating devices on both sides to move upward as well. This ensures that the heating device in the middle and the middle of the curved glass remain in a constant position, guaranteeing that the middle of the glass is heated. The heating devices on both sides are directed towards the curved areas at both ends of the glass, making the transition of the glass's curved contour smoother.

[0029] Example 3

[0030] Please see Figure 3 A longitudinal rotating shaft 39 is movably inserted into one side of the mounting base 31, and a follower gear 310 is fixed at the front end of the rotating shaft 39. The follower gear 310 is used to cooperate with the toothed plate 45. The rotating shaft 39 is located behind the movable rod 38. A vertical groove is opened behind the movable rod 38, and teeth are evenly arranged at the bottom of the vertical groove. An auxiliary gear 311 is fixedly sleeved on the outer wall of the rotating shaft 39 at the position corresponding to the vertical groove. The auxiliary gear 311 rotates the movable rod 38 to move, driving the material ejection assembly 4 to be provided on the top right side of the base plate 11.

[0031] Please see Figure 4The unloading assembly 4 includes an L-shaped frame 41 and a guide plate 44 respectively located at the rear right end and front left end of the conveyor belt device 12. The guide plate 44 is used to allow the formed glass to slide out, and the bottom of the guide plate 44 is fixed with a toothed plate 45 that cooperates with the follower gear 310 by a support rod. As the conveyor belt device 12 drives the receiving assembly 3 to move to the right, the follower gear 310 and the toothed plate 45 cooperate to make the auxiliary gear 311 rotate, driving the movable rod 38 downward, which in turn causes the contact rod 34 to push the formed glass upward. The L-shaped frame 41 has a notch at one end facing the guide plate 44, and the inner wall of the notch is connected to a push plate by a telescopic cylinder 43. The push plate is used for The glass is pushed forward onto the guide plate 44. A detection device 43 is provided on the right side of the L-shaped frame 41 facing the guide plate 44. The detection device 43 can be an infrared emitter and an infrared receiver widely used in the art. The detection device 43 is electrically connected to an external controller. The infrared emitter and the infrared receiver are respectively located on opposite sides of the L-shaped frame 41 and the guide plate 44. When the formed glass is pushed upward as the conveyor belt device 12 blocks the infrared light to the right, the external controller causes the conveyor belt device 12 to stop conveying and causes the telescopic cylinder 42 and the pusher plate to push the glass forward onto the guide plate 44, and the glass is unloaded through the guide plate 44.
