Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending technology, specifically to an adaptive sheet metal bending device. Background Technology

[0002] In the field of sheet metal processing, traditional sheet metal bending equipment generally relies on manual preset parameters (such as bending angle, pressure, speed, etc.) and completes the bending operation through fixed molds. Using equipped molds (general or special molds), cold metal sheets are bent into workpieces of various geometric cross-sectional shapes. External force is used to induce plastic deformation in the metal sheet, thereby forming the required bending angle and shape. It is commonly used to manufacture structural components such as shells, protective covers, brackets, and boxes, ensuring the equipment has a stable structure and a good appearance.

[0003] Die bending has become the mainstream method due to its precision and mass production capabilities. However, in actual use, during sheet metal bending, the sheet metal may be damaged or broken due to its thinness or insufficient strength, or due to the large extrusion and shaping force. The sheet metal bending strength self-adaptability is not good enough, and it cannot automatically adjust the sheet metal extrusion strength. Furthermore, when the sheet metal is subjected to bending extrusion, the bending head applies downward pressure to the stamped part when it contacts the sheet metal part, causing deformation and positional movement in other parts of the sheet metal part. This may cause the sheet metal part to easily deform during bending, thus affecting the bending effect. The anti-deviation positioning capability is also insufficient. Therefore, we propose an adaptive sheet metal bending equipment to solve the above problems. Utility Model Content

[0028] The top of the support frame 2 is provided with a hydraulic lifting component 3, the bottom of the hydraulic lifting component 3 is provided with an elastic damping structure 4, the bottom of the elastic damping structure 4 is provided with a lifting adjustment seat 5, the bottom of the lifting adjustment seat 5 is fixed with a sheet metal bending end 6, and the four corners of the lifting adjustment seat 5 are provided with limit anti-deviation blocks 7, and the four limit anti-deviation blocks 7 are correspondingly slidably connected to the four pillars of the support frame 2.

[0029] A bending die table 8 is provided at the center of the top of the sheet metal bending table 1. Extrusion adjustment arms 9 are provided on both sides of the sheet metal bending table 1. Limiting and positioning ends 10 are provided on the opposite side of the two extrusion adjustment arms 9. An adaptive sensor 11 is provided on the top of the lifting adjustment seat 5.

[0030] The beneficial effects of this solution are as follows: A support frame 2 supports the hydraulic lifting assembly 3. Operating the hydraulic lifting assembly 3 pushes the elastic damping structure 4 and the lifting adjustment seat 5 to move up and down. A sheet metal bending end 6 can be installed at the bottom of the lifting adjustment seat 5. Operating the hydraulic lifting assembly 3 pushes the sheet metal bending end 6, which, in conjunction with the bending die table 8, performs bending operations on the sheet metal parts. During the bending process, the elastic damping structure 4 acts as an elastic damper, allowing the adaptive sensor 11 to be triggered and stop the hydraulic lifting assembly 3, ensuring that the extrusion force of the sheet metal bending end 6 remains stable, preventing damage to the sheet metal parts and exhibiting excellent adaptive capability. Limiting anti-deviation blocks 7 are provided at each of the four corners of the lifting adjustment seat 5, and these blocks follow the support column of the support frame 2 to prevent slippage. Extrusion adjustment arms 9 are correspondingly provided on both sides of the sheet metal bending table 1, which can adjust the support limiting positioning end 10 to position the sheet metal parts. The sheet metal positioning effect is good, resulting in excellent sheet metal strength adaptive capability, good anti-deviation positioning capability, high bending quality, and convenient operation.

[0031] Furthermore, the support frame 2 includes four support columns 21 and a support plate 22. The four support columns 21 are respectively set at the four corners of the top of the sheet metal bending table 1. The support plate 22 is fixedly connected to the top of the four support columns 21. The hydraulic lifting assembly 3 is set in the middle of the support plate 22. The elastic damping structure 4 is set between the hydraulic lifting assembly 3 and the lifting adjustment seat 5. The four limit anti-deviation blocks 7 are respectively slidably connected to the four support columns 21.

[0032] The support frame 2 includes four support columns 21 and a support plate 22. The four support columns 21 can support the support plate 22 and the hydraulic lifting assembly 3. The four limit anti-deviation blocks 7 are respectively slidably connected to the four support columns 21, so as to prevent deviation and stabilize the positioning.

[0033] Furthermore, the hydraulic lifting assembly 3 includes two sets of hydraulic cylinders 31 and a lifting mounting plate 32. The two hydraulic cylinders 31 are correspondingly installed inside the top of the support frame 2, and the bottom of the two hydraulic cylinders 31 extends into the interior of the support frame 2 and is fixedly connected to the top of the lifting mounting plate 32.

[0034] The hydraulic lifting assembly 3 includes two sets of hydraulic cylinders 31 and a lifting mounting plate 32. The two sets of hydraulic cylinders 31 are distributed accordingly and the lifting displacement is stable. The lifting mounting plate 32 plays a role in installation and bearing. The lifting mounting plate 32 can support the elastic damping structure 4. The elastic damping structure 4 has good elastic damping activity and excellent adaptability.

[0035] Furthermore, the lifting mounting plate 32 and the lifting adjustment seat 5 remain parallel and horizontal, and the bending die table 8 is located directly above the limit anti-deviation block 7;

[0036] By setting the lifting mounting plate 32 and the lifting adjustment seat 5 to be kept parallel and horizontal, the lifting is stable and convenient. The bending die table 8 is located directly above the limit anti-deviation block 7, so that after the limit anti-deviation block 7 is lifted, it can squeeze and position the bending die table 8 to cooperate in the sheet metal bending operation.

[0037] Furthermore, the elastic damping structure 4 includes a damping cylinder 41, a damping rod 42, and a high-strength spring 43.

The top of the damping rod 42 extends and slides dampingly on the inner side of the damping cylinder 41. The high-strength spring 43 is sleeved on the outer side of the damping cylinder 41 and the damping rod 42. The two ends of the high-strength spring 43 are respectively connected to the hydraulic lifting assembly 3 and the lifting adjustment seat 5.

[0038] By setting up an elastic damping structure 4, including a damping cylinder 41, a damping rod 42, and a high-strength spring 43, the damping cylinder 41 and the damping rod 42 play a supporting and buffering role, and can be contracted for damping. The high-strength spring 43 plays an elastic supporting role, and can be elastically contracted for support. The overall elastic damping effect is good, which facilitates the adaptive adjustment of the device.

[0040] By setting the height of the adaptive sensor 11 to be less than the extended length of the elastic damping structure 4, the adaptive sensor 11 can be used for contact. After the adaptive sensor 11 is triggered by contact, the hydraulic lifting assembly 3 can be controlled to stop running, which facilitates adaptive adjustment of bending.

[0041] Furthermore, the extrusion adjustment arm 9 includes a bearing plate 91, two sets of movable support arms 92 and fixing nuts 93.

The fixing nuts 93 are extruded and fixed on both sides of the bearing plate 91. The limiting and positioning end 10 is fixedly installed on the side of the movable support arm 92 near the bending die table 8.

[0042] By setting the compression adjustment arm 9, which includes a bearing plate 91, two sets of movable support arms 92 and a fixing nut 93, the bearing plate 91 can support the extension and retraction displacement of the two sets of movable support arms 92, and the fixing nut 93 can fix the movable support arms 92, so that the movable support arms 92 can support and control the limit positioning end 10, and the adaptability is good.

[0044] Working principle: A support frame 2 is provided on the top of the sheet metal bending table 1 to support and bear the hydraulic lifting component 3. Running the hydraulic lifting component 3 can push the elastic damping structure 4 and the lifting adjustment seat 5 to move up and down. The elastic damping structure 4 plays an elastic buffering and damping role. The bottom of the lifting adjustment seat 5 can be installed with the sheet metal bending end 6. The top of the sheet metal bending table 1 is provided with a bending mold table 8. Running the hydraulic lifting component 3 can push the sheet metal bending end 6, and cooperate with the bending mold table 8 to perform bending production operations on the sheet metal parts. During the bending process, the elastic damping structure 4 plays a buffering role. When the elastic damping structure 4 is compressed by force, the lifting adjustment seat 5 approaches the hydraulic lifting component 3, so that the adaptive sensor 11 can be contacted and triggered, so that the extrusion force of the sheet metal bending end 6 remains stable, and it is not easy to damage the sheet metal parts. It has excellent adaptive ability.

[0045] The lifting and adjusting seat 5 is equipped with limit anti-deviation blocks 7 at each of its four corners. When the lifting and adjusting seat 5 is raised or lowered, the four sets of limit anti-deviation blocks 7 move up and down along the support column of the support frame 2, providing excellent anti-deviation positioning capability. The sheet metal bending table 1 is equipped with extrusion adjustment arms 9 on both sides, which can adjust the support limit positioning end 10, making it easy to adjust the displacement of the limit positioning end 10, so that the limit positioning end 10 can position the sheet metal part.
