Description

Technical Field

[0001] This utility model relates to the field of bending die technology, and in particular to a bending die with an elastic buffer bending material support structure. Background Technology

[0002] Bending dies are tools used to shape and process sheet metal. They mainly achieve the processing of the shape of an item by changing the physical state of the material being shaped, so that the sheet metal is shaped into a specific shape and size under pressure. The material support structure is an important component of bending dies.

[0003] A search revealed a V-shaped seamless bending die structure with publication number CN213436678U. This structure includes a base, a lower die core, and a bending die mounted on the base. The lower die core is movable up and down, and its bottom is V-shaped. The bending die includes a first bending groove and a second bending groove symmetrically arranged on the base, a first bending block within the first bending groove, and a second bending block within the second bending groove. The lower die core is positioned above the axis of symmetry of the first and second bending grooves. The first and second bending grooves have identical structures, with the first bending groove being arc-shaped. The first and second bending blocks also have identical structures, with the bottom of the first bending block being arc-shaped. The centers of the first bending block and the first bending groove are the same, and the first bending block is coaxially positioned within the first bending groove through its center. The workpiece is placed on the first and second bending blocks.

[0004] Based on the aforementioned patents, the existing technology has the following shortcomings: The bending die in the existing technology uses a combination of an arc plate, a pressure plate, and springs to form the material support structure of the bending die. However, due to the presence of the spring's restoring force, the material support structure will quickly return to its original position. Furthermore, since the material support structure does not have a buffer function, it will collide during the return process, resulting in noise problems and damage to the material support structure. Therefore, it is urgent to design a bending die with an elastic buffer bending material support structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bending die with an elastic buffer bending support structure. Its advantages lie in providing a better buffering effect throughout the support structure, preventing collision damage to the support platform during resetting, and improving the overall service life of the bending die.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bending die employing an elastic buffer bending material support structure includes a support frame.

[0038] Example 1

[0039] Reference Figure 1-6A bending die employing an elastic buffer bending material support structure includes a support 1. A top plate 7 is fixedly installed on the top of the support 1, and a pressure die assembly is provided on the top plate 7. The pressure die assembly includes a hydraulic cylinder 9 fixedly installed on the top of the top plate 7, and an upper die base 14 is fixedly installed on the piston end of the hydraulic cylinder 9.

Material support platforms 4 are slidably arranged on the inner walls of the arc-shaped grooves 16. The position of the bending pressure head 6 corresponds to the position of the gap between the two material support platforms 4. The outer walls of both ends of the lower die base 2 are provided with equally spaced mounting grooves 11, and the bottom of each mounting groove 11 is fixedly installed with a first spring 3 on one side of the bottom of the material support platform 4. The material support platform 4 is composed of an arc plate and a pressure plate, and the top end of the first spring 3 is fixedly installed on the bottom of the pressure plate. Buffer structures 10 are provided at both ends of the top of the lower die base 2. The top surface of the material support table 4 is attached to one side of the bottom surface of the material support table 4. The buffer structure 10 includes multiple grooves 1002 formed at both ends of the top of the lower die base 2. The positions of the grooves 1002 and the mounting grooves 11 are staggered. The bottom of each groove 1002 is fixedly installed with a fixed seat 1004. The top of each fixed seat 1004 is fixedly installed with telescopic rods 1005 distributed at equal intervals. The top of each telescopic rod 1005 is fixedly installed with a support seat 1001. The outer wall of each telescopic rod 1005 is fixedly installed with a fixing ring 1006. The top of each fixing ring 1006 and the bottom of the support seat 1001 are fixedly installed with a third spring 1007. The material support table 4, the first spring 3 and the buffer structure 10 are combined to form the elastic buffer material support structure of the entire bending die. When the material support table 4 is reset by the reset force of the first spring 3, the buffer structure 10 is used to buffer the material support table 4, avoiding the problem of collision damage to the material support table 4 during reset, and improving the service life of the entire bending die.

[0040] To facilitate the sliding of the material support platform 4, refer to... Figure 2 , Figure 5 and Figure 6 The inner wall of the arc groove 16 is fixedly equipped with arc slide rails 12 that are evenly distributed, and the bottom surface of the arc plate is fixedly equipped with arc slide blocks 13 that are slidably arranged in the arc slide rails 12 at equal distances.

The guide frame 8 and the guide hole 15 mentioned above ensure the stability of the upper mold base 14 when it is raised and lowered, and the entire bending mold is easy to carry under the action of the guide frame 8.

[0043] Example 2

[0044] Reference Figure 1 , Figure 2 and Figure 4 Compared to Embodiment 1, this embodiment has a protective component 5 on the bending head 6. The protective component 5 includes connecting plates 504 fixedly installed on the outer walls of both sides of the upper die base 14. Each connecting plate 504 has a through hole, and a column 502 is inserted into the inner wall of each through hole. The same protective cover 501 is fixedly installed at the bottom of the column 502. A through groove 505 for the bending head 6 to pass through is opened in the middle of the protective cover 501. A second spring 503 sleeved on the outside of the column 502 is fixedly installed at the top of the protective cover 501 and the bottom of the connecting plate 504. After bending, the workpiece can be protected by the protective component 5 to prevent the workpiece from rebounding and breaking out.

[0045] Working principle: During use, the user places the workpiece on the two support platforms 4. The hydraulic cylinder 9 in the pressure mold assembly lowers the height of the upper mold base 14, the bending pressure head 6, and the protective assembly 5, squeezing the two support platforms 4 to rotate. This causes the first spring 3 to stretch, thereby bending the workpiece. After bending, the hydraulic cylinder 9 drives the pressure mold assembly to reset, allowing the support platforms 4 to reset by the reset force of the first spring 3. The buffer structure 10 buffers the support platforms 4 to avoid collision damage during reset. The damping pad 1003 also reduces noise during reset. The protective assembly 5 protects the workpiece after bending to prevent it from rebounding and breaking out.

[0046] 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.
