Description

Technical Field

[0001] The utility model relates to the technical field of door cover processing equipment, in particular to a door cover bending machine. Background Art

[0002] In the construction industry, the production and installation of doors is a key link. The door cover (or door frame) is the fixed structure of the door. It not only supports and fixes the door leaf, but also serves as a decoration and enhances the structural integrity. The production of door covers involves a variety of materials, including wood, metal (such as aluminum, steel, etc.) and plastic. These materials need to be precisely processed to adapt to different door opening sizes and design requirements. The traditional door cover processing method includes cutting, assembly and bending. Among them, bending is the key process to form a specific shape of the door cover. It requires that the material must reach the required angle and curvature without damaging the material. The quality of the bending process directly affects the appearance texture and structural stability of the door cover, and is an important link in the production of high-quality door covers.

[0003] Although the manufacturing process of door frames is constantly improving, the traditional door frame bending process still faces many challenges, especially in terms of operational safety and efficiency. In traditional bending operations, operators often need to manually support, support and adjust the metal plate of the door frame for bending, which poses a safety hazard. Since the metal plate may suddenly move or slip during the bending process, especially at the bending edge, the operator is prone to the risk of pinching his hands. In addition, long-term hand-held support and adjustment also increase the labor intensity of the operator, which is particularly obvious in continuous operations, which can easily lead to fatigue of the workers and further increase the risk of work-related accidents. Therefore, there is an urgent need for a new type of mechanical equipment that can improve the safety and efficiency of door frame bending operations to ensure the personal safety of operators while improving production efficiency and product quality.

In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined. Example

[0033] See also Figure 1-7 As shown, the utility model provides a technical solution of a door cover bending machine: a door cover bending machine, comprising a frame 1, a cylinder 2 is installed on the top of the frame 1, a bending plate 3 is connected to the bottom of the cylinder 2, a base 4 is placed directly below the bending plate 3, and an auxiliary positioning mechanism 5 is installed on the side of the frame 1;

[0034] The auxiliary positioning mechanism 5 includes a plurality of first positioning members 501, a rotating shaft 502, and a locking mechanism 505. The first positioning member 501 is fixedly mounted on the side of the frame 1, and the rotating shaft 502 is rotatably connected to the inner side of the first positioning member 501. A plurality of height adjustment plates 503 are fixedly mounted on the side of the rotating shaft 502. The top of the height adjustment plate 503 is rotatably connected to an angle adjustment plate 504. The locking mechanism 505 is mounted on the side of the rotating shaft 502. The locking mechanism 505 is used to limit the movement of the rotating shaft 502. When the door cover is bent, the operator first needs to rotate the rotating shaft 502 to adjust the height of the door cover. 02, adjust the height of the top position of the height adjustment plate 503, and then lock the rotating shaft 502 through the locking mechanism 505 to prevent the rotating shaft 502 from rotating during the bending process. Finally, place the bent part of the door frame metal plate on the base 4, and place its back on the angle adjustment plate 504 for fine-tuning the angle. Finally, press the bending plate 3 down by the cylinder 2 to complete the bending at the specified position. In this design, the height adjustment plate 503 and the angle adjustment plate 504 can replace human hands to provide support for the door frame metal plate close to the base 4, reduce the risk of pinching the operator's hands, and improve operational safety.

[0035] The locking mechanism 505 includes a second positioning member 5051, a convex portion 5055, and a lower locking ring 5057. The second positioning member 5051 is fixedly installed on the side of the frame 1. The second positioning member 5051 is slidably connected with a locking rod 5052 inside. The end of the locking rod 5052 facing the rotating shaft 502 is designed with a concave portion 5053. A locking plate 5054 is installed on the side of the locking rod 5052. The convex portion 5055 is designed at the end of the rotating shaft 502 facing the locking rod 5052. The concave portion 5053 and the convex portion 5055 match each other. The surfaces of the concave portion 5053 and the convex portion 5055 are both arranged with an anti-slip rubber layer 5056. The lower locking ring 5057 is installed on the side of the frame 1. The side of the lower locking ring 5057 is rotatably connected with an upper locking ring 5058. The lower locking ring A through hole 5059 is reserved between 5057 and the upper locking ring 5058 for facilitating the movement of the locking rod 5052. A locking cavity 5060 matching the locking plate 5054 is provided inside the upper locking ring 5058. When it is necessary to lock the rotating shaft 502, the operator needs to lift up the upper locking ring 5058 and then push the locking rod 5052 toward the convex portion 5055 of the rotating shaft 502. When the recessed portion 5053 and the convex portion 5055 are connected, the locking plate 5054 will fall into the locking range of the locking cavity 5060. At this time, when the operator fastens the upper locking ring 5058 on the lower locking ring 5057, the locking rod 5052 will be unable to move, and the rotating shaft 502 will be unable to rotate, thereby achieving a locking effect. This design makes the operation process simple and intuitive, and easier to understand and execute.

[0036] An orientation groove 6 is provided on the inner side of the second positioning member 5051, and an orientation plate 7 matching the orientation groove 6 is connected to the side of the locking rod 5052. This design can effectively prevent the locking rod 5052 from rotating during the pushing process of the operator, thereby ensuring that the locking plate 5054 can quickly and accurately enter the locking range of the locking cavity 5060 during each locking operation, thereby improving operating efficiency.

[0037] The upper end surface of the angle adjustment plate 504 is provided with a rubber buffer plate 8, which can provide a soft contact surface during the bending process, effectively reducing the scratches or damage that may occur between the back of the door frame metal plate and the top of the angle adjustment plate 504 during bending.

[0038] A toggle groove 9 is provided on the surface of the upper locking ring 5058. The setting of the groove allows the operator to quickly unlock the closed upper locking ring 5058 by simply pushing it with the thumb. This design greatly improves the unlocking efficiency and provides the user with a fast and intuitive unlocking method.

[0039] A push plate 10 is provided on the top of the locking rod 5052. The push plate 10 can provide the operator with a better gripping point, making the manual push operation easier and more suitable for frequent operations such as door frame bending.

[0040] The working principle of the utility model is as follows:

[0041] When using a door frame bending machine of the present embodiment, it is first necessary to ensure that the upper locking ring 5058 is in an open state, and then pre-adjust the top height of the height adjustment plate 503 roughly according to the bending condition of the door frame metal plate. After the pre-adjustment is completed, the locking rod 5052 is pushed in the direction of the protrusion 5055 of the rotating shaft 502, and the upper locking ring 5058 is covered. At this time, the locking plate 5054 on the locking rod 5052 will fall into the interior of the locking cavity 5060 to ensure that the position of the height adjustment plate 503 is locked. Finally, the bent part of the door frame metal plate is placed on the base 4, and its back is placed on the angle adjustment plate 504 for fine-tuning the angle. The bending at the specified position can be completed by controlling the cylinder 2 to press down the bending plate 3; the door frame bending machine improves the operating safety and efficiency through the auxiliary positioning mechanism 5 and the locking mechanism 505. The auxiliary positioning mechanism 5 reduces the risk of pinching hands and protects the safety of operators. The locking mechanism 505 simplifies the operating process, ensures the stability of the rotating shaft, and improves work efficiency and reliability.
