Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a large-area product perimeter support device for bending molds. Background Technology

[0002] With the development of the bending die industry, various types of bending dies have been widely used. However, these products still have some problems in actual use. For example, when bending large sheet metal parts, due to the limitations of existing die structure design, it is often difficult to ensure that the product is uniformly supported on all four sides during processing. This results in the product being suspended and unbalanced after installation, causing asymmetry or deviation in the bent area, which affects product quality and production efficiency.

[0003] In the prior art, a bending die with publication number CN114433725B and publication date March 12, 2024, is found. This design achieves synchronous pressing by driving the side and corner ejection components with the lower die, and completes synchronous bending operations by driving the side and corner bending components with the upper die, thereby eliminating the mold mark problem caused by asynchronous bending. However, the design focus of this die is on the synchronization and precision control during the bending process, and it has not been specifically optimized for the four-sided support of large-area products. It relies only on a limited number of pins to fix the sheet metal parts, which cannot effectively solve the problem of product imbalance in the air, and easily leads to inconsistent product dimensions after bending, especially when processing large-area workpieces.

[0004] Another prior art, a bending die with publication number CN110695210B, published on August 20, 2021, uses an upper and lower die cooperation method. A wedge mechanism pushes a sliding module to achieve the bending action, ensuring proper bending and avoiding damage to the product surface. While this die has good bending performance, its structural design primarily focuses on precise control of single or multi-point bending areas, without fully considering the overall stability of large-area workpieces. In practical applications, if the workpiece area is large and it is positioned only by two sets of pins, insufficient support may cause the product to tilt or even deform, further affecting the bending quality.

[0005] Therefore, it is necessary to design a large-area product perimeter support device for bending dies to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a large-area product perimeter support device for bending dies, in order to overcome the aforementioned shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A large-area product perimeter support device for bending dies, comprising: The base module includes a base plate and a plurality of mounting holes provided on the base plate; The contouring support module is located above the base plate and includes a contouring plate adapted to the shape of the workpiece to be processed, and the contouring plate is provided with several positioning pins. The support module is arranged around the contour plate and includes several independent support units. Each support unit includes a mounting base, a support arm movably connected to the mounting base, and an elastic reset mechanism arranged on the support arm.

[0008] Preferably, the mounting base of the support unit is fixed to the outer periphery of the profile plate by bolts.

[0009] Preferably, the support arm is rotatably connected to the mounting base via a pivot.

[0010] Preferably, the elastic reset mechanism includes a spring and a limiting groove formed in the mounting base to limit the rotation angle of the support arm. One end of the spring is fixed to the mounting base, and the other end is connected to the bottom of the support arm.

[0011] Preferably, the locating pin is threaded onto the profile plate.

[0012] Preferably, the support unit further includes a pressure sensor, which is disposed at the top of the support arm.

[0013] The beneficial effects of this utility model are as follows: This technical solution achieves uniform support for large-area workpieces by setting multiple independent support units around the contour plate, avoiding the phenomenon of unbalanced suspension caused by insufficient support during bending; during the bending process, the drive support arm flips downward to avoid the workpiece, ensuring the smooth progress of the bending action; at the same time, after the bending is completed, the support arm is automatically reset by the elastic reset mechanism, preparing for the next processing, solving the problem of unbalanced suspension of large-area workpieces during bending in the prior art, while improving bending quality and production efficiency, and has significant technical progress and practicality.

[0015] Reference Figures 1 to 3 A large-area product perimeter support device for bending dies, comprising a base module, including a base plate 1 and a plurality of mounting holes disposed on the base plate; The contouring support module 2 is disposed above the base plate 1 and includes a contouring plate 21 adapted to the shape of the workpiece to be processed, and the contouring plate 21 is provided with a plurality of positioning pins 22. The support module 3 is arranged around the contour plate 21 and includes several independent support units. Each support unit includes a mounting base 31, a support arm 32 movably connected to the mounting base 31, and an elastic reset mechanism 33 arranged on the support arm 32. The base module includes a base plate 1, which serves as the base of the entire device. Several mounting holes are provided on the base plate for fixing the device to the worktable of the bending equipment. The top of the base plate 1 is connected to the contour plate 21 in the contour bearing module via bolts. The contour plate 21 is located above the base plate 1 and remains parallel to it. The shape of the contour plate 21 is designed to fit the shape of the workpiece to be processed. Several positioning pins 22 are provided on its surface. The positioning pins 22 are threaded onto the contour plate 21 and their positions can be adjusted according to the size and shape of the workpiece to ensure accurate positioning of the workpiece before bending.

[0016] Support modules 3 are arranged around the contour plate 21, and their core components are several independent support units. Each support unit includes a mounting base 31, a support arm 32, and an elastic reset mechanism 33. The mounting bases 31 are fixed to the outer periphery of the contour plate 21 by bolts. The spacing between the mounting bases 31 is set according to the size and shape of the workpiece to ensure that the workpiece is evenly stressed around its periphery. The support arm 32 is rotatably connected to the mounting base via a pivot, allowing the support arm 32 to rotate within a certain angle range. The top end of the support arm 32 contacts the workpiece.

[0017] The elastic reset mechanism 4 includes a spring and a limiting groove 41 formed in the mounting base 31. One end of the spring is fixed to the mounting base 31, and the other end is connected to the bottom of the support arm 32. When the support arm 32 is subjected to external force, the spring will be stretched or compressed, thereby realizing the automatic reset function of the support arm 32. The limiting groove 41 is used to limit the flipping angle of the support arm 32 to prevent the support arm 32 from flipping excessively during operation and affecting the stability of the workpiece.

[0018] In other implementation examples, each support unit also includes a pressure sensor, which is located at the top of the support arm 3 to monitor the pressure of the workpiece on the support arm 3 in real time, so as to adjust the support force in a timely manner during the bending process and ensure the stability of the workpiece during the bending process.

[0019] The operating principle of this utility model is as follows: During use, the workpiece to be processed is first placed on the contour plate 21. By adjusting the position of the positioning pin 22, the workpiece is accurately positioned on the contour plate 21. Then, the workpiece is brought into contact with the support arm 32 in the support module. At this time, the support arm 32 applies a certain supporting force to the workpiece under the action of the elastic reset mechanism 33, ensuring that the workpiece will not be suspended or unbalanced before bending. During the bending process, the bending assembly presses down, causing the support arm 32 to rotate downwards, thereby providing sufficient operating space for the workpiece. After the bending action is completed, the support arm 32 automatically resets under the action of the elastic reset mechanism 33, preparing for the next processing.

[0020] Throughout the bending process, the shape of the contour plate 21 is adapted to the workpiece's outline, further enhancing the workpiece's positioning accuracy. The flexible adjustment function of the positioning pin 9 ensures precise positioning of the workpiece before and after bending. Simultaneously, the even distribution of multiple independent support units in the support module ensures more balanced force distribution around the workpiece, fundamentally solving the problem of unbalanced suspension caused by insufficient support in existing technologies.

[0021] The advantages of this utility model are that by setting multiple independent support units around the contour plate, uniform support for large-area workpieces is achieved, avoiding the unbalanced suspension caused by insufficient support during bending. During bending, the support arm is driven to flip downward to avoid the workpiece, ensuring the smooth progress of the bending action. At the same time, after bending is completed, the support arm is automatically reset by the elastic reset mechanism, preparing for the next processing. This solves the problem of unbalanced suspension of large-area workpieces during bending in the prior art, while improving bending quality and production efficiency, and has significant technical progress and practicality.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
