Abstract
Description
Technical Field
[0001] This application relates to the technical field of bending tooling, and in particular to a bending tooling and bending equipment for door leaf hinge cover plates. Background Art
[0002] A door leaf hinge cover plate is a component related to door and window installation. It is usually used to connect the door leaf and the door frame and allows the door leaf to rotate around the hinge axis, thereby realizing the opening and closing of the door. The hinge cover plate is generally installed at the connection between the door leaf and the door frame, bears the weight of the door leaf, and ensures that the door leaf can rotate smoothly and flexibly. In door and window installation, choosing a suitable hinge cover plate is very important for ensuring the stability and service life of the door.
[0003] In the field of machining, for the bending operation of thin plates, a bending machine is usually used. However, for specific shapes, such as the cross-sectional shape of a door leaf hinge cover plate is generally a circular bottom V-shaped thin plate, a conventional bending machine may not be able to meet the precise bending requirements. At present, for the bending of thin plates with special shapes, some enterprises will use customized bending dies or manual operations to complete. However, although customized dies can meet the bending requirements of specific shapes, once the product shape changes, the dies need to be remade, which is costly and time-consuming, and has poor flexibility; manual operations are inefficient and greatly affected by human factors, and cannot guarantee the consistency of products, making it difficult to ensure the accuracy of the products obtained after manual bending and forming. Summary of the Utility Model

[0017] By adopting the above technical solution, the designed connection reinforcement plate can improve the connection strength between the bending reinforcement plate and the side plate, and further ensure the stability of the relative position relationship between the side plate and the bottom plate.
[0018] In a specific possible implementation manner, the top wall of the connecting reinforcement plate is arranged coplanar with the top wall of the side plate.
[0019] By adopting the above technical solution, the connecting reinforcement plate designed to be coplanar with the top wall of the side plate can provide support for the thin plate in a larger plane range, avoiding the possibility of the thin plate bending downward due to its own gravity after being placed.
[0020] In a specific possible implementation scheme, two lifting holes are provided on the bottom plate, and the lifting holes are arranged close to two ends of the long sides of the bending cavity.
[0021] By adopting the above technical solution, the designed lifting holes can facilitate the movement of the tooling through the hook, thereby completing the installation and disassembly of the tooling.

In this embodiment, the number of positioning blocks 3 is preferably two.
[0045] Referring to Figure 1, due to the relatively large combined mass of the bottom plate 1, the side plates 2, and the positioning stoppers 3, in order to facilitate the operator to move the tooling, two lifting holes 11 are provided on the bottom plate 1, and the two lifting holes 11 are respectively arranged near the two ends of the long side of the bending cavity.
[0046] Referring to Figure 2 , in order to facilitate the thin plate to naturally fold upward after being pressed by the forming tube 8, and reduce the possibility that the movement of the thin plate is hindered by the edge burrs and the positioning stoppers 3, affecting the quality of the bent product, the included angle between the positioning surface of the positioning stoppers 3 and the plane where the top walls of the two side plates 2 are located is greater than ninety degrees, and the positioning surface of the positioning stoppers 3 is polished to be smooth.
[0047] Referring to Figure 3 , in order to improve the connection strength and bending strength between the bottom plate 1 and the side plates 2, and extend the service life of the tooling, the door leaf hinge plate bending tooling further includes two bending strengthening plates 4. The bending strengthening plates 4 are integrally formed with the bottom plate 1. The cross-sectional shapes of the bottom plate 1 and the two bending strengthening plates 4 are in the shape of "I", and the bending strengthening plates 4 are fixedly welded to the outer side walls of the side plates 2.
[0048] Referring to Figure 4 , in order to improve the connection strength between the side plates 2 and the bending strengthening plates 4, the door leaf hinge plate bending tooling further includes a plurality of connection strengthening plates 5. The plurality of connection strengthening plates 5 are distributed along the long side direction of the bending cavity, and the connection strengthening plates 5 are perpendicularly welded to the side plates 2 and fixedly welded to the bending strengthening plates 4.

[0050] The implementation principle of a door leaf hinge plate bending tooling according to an embodiment of the present application is as follows: The sheet material is pre-cut according to the size of the door leaf hinge plate to obtain a thin plate, and then a force is applied to the thin plate so that one end of the thin plate abuts against the positioning surface of the positioning stopper 3. At this time, the position of the thin plate is determined, and then a force is applied to the forming tube 8 through the press 7, so that the forming tube 8 moves toward the thin plate side until the forming tube 8 contacts the thin plate and continues to feed to obtain a thin plate structure with a round-bottom V shape, that is, the door leaf hinge plate.

[0054] The implementation principle of a bending device in an embodiment of this application is as follows: First, the door leaf hinge plate bending tooling is installed on the placement area of the machine table 6 through a hoisting device cooperating with the hoisting hole 11. Then, the plate is pre-cut according to the size of the door leaf hinge plate to obtain a thin plate. Then, a force is applied to the thin plate so that one end of the thin plate abuts against the positioning surface of the positioning block 3. At this time, the position of the thin plate is determined. Then, a force is applied to the forming tube 8 through the press 7, so that the forming tube 8 moves toward the thin plate side until the forming tube 8 contacts the thin plate and continues to feed to obtain a thin plate structure with a round-bottom V shape, that is, the door leaf hinge plate.
