Description

Technical Field

[0001] The utility model relates to the technical field of metal sheet processing, in particular to a forging bending die. Background Art

[0002] Forgings are metal products obtained through the forging process in metal processing production technology. Metal sheet bending is a commonly used technology in metal processing, which can transform a flat metal sheet into a shape that meets specific design and functional requirements. Whether in the fields of machinery manufacturing, aerospace, automotive manufacturing, household appliances, or the construction industry, etc., bending technology is required to obtain the required shape and structural strength. Generally, when bending metal, it is most commonly bent into a U-shaped bend.

[0003] Traditional bending methods mainly rely on manual operation. Workers usually need to use simple machinery to bend the sheet to the required shape. However, during the manual operation process, due to human factors, each sheet is prone to uneven stress, resulting in large errors in the bending angle and size, and it is difficult to meet the product quality requirements. At the same time, the metal will deform during the bending process, and the non-bending points of the sheet will also displace under stress, which increases the risk of the metal edge becoming sharp, thus easily scratching the skin of workers and posing a safety hazard. In addition, the manual-dependent bending method is not only inefficient but also difficult to ensure the consistency of product quality.

[0004] Therefore, to solve the above problems, a forging bending die is proposed. Summary of the Utility Model

[0010] A second cylinder is installed at the bottom end of the top plate of the frame, and a pressing plate is installed at the bottom end of the output shaft of the second cylinder. The pressing plate is horizontally located between the conveyor belt and the bending groove.

[0011] Furthermore, both joints between the two lateral sides of the upper end of the bending groove along the transverse direction of the mold table and the upper surface of the mold table are arranged in smooth arc shapes.

[0012] Furthermore, both ends of the rotating rod are rotatably connected to two mounting plates through bearings, and the upper mold is rotatably connected to the mounting plates through the rotating rod.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-3 , a forging bending die in this embodiment, through the bending component 4 installed under the top plate of the frame 11, uses the first cylinder 41 to push the upper die 45 to move up and down, realizing the bending of metal plates. Through precise control systems and calibration, the consistency of the bending of metal plates can be ensured, thereby improving product quality. At the same time, the second cylinder 5 is used to push the pressing plate 51 to fix the unbent part of the metal plate, preventing its unexpected movement during the bending process, and thus reducing the risk of injury to workers. Compared with the traditional manual bending method, this mechanized bending method can more effectively ensure the consistency of product quality and improve production efficiency.

[0026] Specifically, a forging bending die in this embodiment includes a die table 1, a conveyor belt 2, and a bending component 4. The conveyor belt 2 is installed on one side of the die table 1;

[0027] On one side of the upper surface of the die table 1, a frame 11 is installed, and a bending component 4 is installed at the bottom of the top plate of the frame 11;

[0028] The bending assembly 4 includes a first cylinder 41, which is mounted on the lower surface of the top plate of the frame 11. The output shaft of the first cylinder 41 is arranged downward and a receiving plate 42 is arranged at the bottom. Two mounting plates 43 are arranged at the bottom of the receiving plate 42 along the longitudinal sides of the die table 1. A rotating rod 44 is arranged between the lower ends of the two mounting plates 43. The rotating rod 44 penetrates the two mounting plates 43 along the longitudinal direction of the die table 1. An upper mold 45 is sleeved on the outer surface of the rotating rod 44. The upper mold 45 is arranged in a cylindrical shape and is located between the two mounting plates 43.

[0029] A bending groove 3 is provided on the upper surface of the die table 1 along the longitudinal direction of the die table 1. The bending groove 3 is arranged in a U-shape along the cross section of the die table 1. The bending groove 3 corresponds to the upper die 45.

[0030] The second cylinder 5 is installed at the bottom end of the top plate of the frame 11, and a pressing plate 51 is installed at the bottom end of the output shaft of the second cylinder 5. The pressing plate 51 is located between the conveyor belt 2 and the bending groove 3 in the horizontal direction.

[0031] During actual use, the staff places the metal plate on the conveyor belt 2, and then controls the conveyor belt 2 to run. Under the conveyance of the conveyor belt 2, the metal plate will be slowly transported to the mold platform 1; when the part of the metal plate that needs to be bent is located below the upper mold 45, the staff controls the conveyor belt 2 to stop running, and then controls the second cylinder 5 and the first cylinder 41 to run respectively. The second cylinder 5 drives the pressing plate 51 to move downward, close to the metal plate but not connected; the first cylinder 41 drives the upper mold 45 downward through the receiving plate 42 and the mounting plate 43, and pushes the metal plate down to the bottom of the bending groove 3 to bend the metal plate. Under the push of the first cylinder 41, the metal plate is evenly stressed, so as to solve the problem that each plate is easily unevenly stressed due to traditional manual bending; at the same time, under the restriction of the pressing plate 51, the end of the metal plate that is not pressed is prevented from quickly tilting up under the pressure of the upper mold 45, thereby causing harm to the staff.

[0032] The upper ends of the bending grooves 3 are arranged in a smooth arc shape along the lateral sides of the mold platform 1 and connected to the upper surface of the mold platform 1 .

[0033] The smooth arc-shaped design at the upper end of the bending groove 3 enables the metal sheet to pass through the bending groove 3 more smoothly during the bending process, reducing the jamming or hanging phenomenon of the material during the bending process, thereby improving the smoothness and safety of the operation.

[0034] Both ends of the rotating rod 44 are rotatably connected to the two mounting plates 43 through bearings, and the upper mold 45 is rotatably connected to the mounting plates 43 through the rotating rod 44 .

[0035] A rotating motor 46 is mounted on the outer wall of one of the mounting plates 43 , and a crawler belt 47 is tensionedly connected between the outer wall of the output shaft of the rotating motor 46 and the outer wall of one end of the rotating rod 44 .

[0036] The rotating upper die 45 has a softer contact with the sheet metal during the bending process, which can reduce indentation, scratching or other forms of damage to the sheet metal and maintain the surface quality of the sheet metal.

[0037] A groove is provided on the outer side wall of the upper die 45, and a heating coil 48 is installed in the groove.

[0038] The heating coil 48 can heat the metal plate, and the local area of the metal sheet is rapidly heated, reducing its yield point and making the metal plate easier to deform. At the same time, during the rotation of the heating coil 48 with the upper die 45, the metal plate is heated more evenly, improving the bending efficiency and bending quality of the metal plate.

[0039] An infrared positioning instrument 6 is installed on the lower surface of one of the mounting plates 43, and the beam irradiation range of the infrared positioning instrument 6 corresponds to the bending groove 3.

[0040] With the cooperation of the infrared positioning instrument 6, the bending position of the metal plate can be made more accurate.

[0041] A third cylinder 52 is installed on the upper surface of the die table 1 on the side away from the conveyor belt 2. The output shaft of the third cylinder 52 is oriented towards the conveyor belt 2 and a support plate 53 is installed at its tail end, which can prevent the metal plate from moving with the rotation of the upper die 45 when the upper die 45 contacts the metal plate, affecting the accuracy of metal plate bending.

[0042] Baffles 21 are installed at the upper ends of the side plates on both sides of the conveyor belt 2. At least one spring 22 is installed on the opposite surfaces of the two baffles 21, and a positioning plate 23 is installed at the mutually approaching ends of at least two springs 22.

[0043] With the assistance of the positioning plate 23, when the metal plate moves on the conveyor belt 2, its placement orientation can be adjusted, thereby further ensuring the accuracy of metal plate bending.

[0044] The working principle of the above embodiment is as follows:

[0045] The staff places the metal plate on the conveyor belt 2, and then controls the operation of the conveyor belt 2 and the infrared locator 6. Under the conveyance of the conveyor belt 2, the metal plate will be slowly transported onto the mold table 1; when the part of the metal plate that needs to be bent is located below the upper mold 45 under the irradiation of the infrared locator 6, the staff controls the conveyor belt 2 to stop running and controls the operation of the third cylinder 52. The third cylinder 52 pushes the support plate 53 to slide on the mold table 1 and connect with the metal plate to prevent the subsequent metal plate from moving as the upper mold 45 rotates. The staff then separately controls the operation of the second cylinder 5, the rotating motor 46, the heating coil 48, and the first cylinder 41. The operation of the second cylinder 5 pushes the pressing plate 51 downward to approach but not connect with the metal plate; the operation of the first cylinder 41 pushes the upper mold 45 downward through the bearing plate 42 and the mounting plate 43, pushing the metal plate downward to the bottom of the bending groove 3 to bend the metal plate. Under the action of the rotating motor 46, the upper mold 45 can be driven to rotate. As the heating coil 48 rotates with the upper mold 45, the metal plate is heated evenly, making it more convenient to bend. During the bending process of the metal plate, under the restriction of the pressing plate 51, the un-pressed end of the metal plate can be prevented from quickly tilting under the pressure of the upper mold 45, thereby causing harm to the staff.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
