Description

Technical Field

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

[0002] Automotive electronic and electrical components require compact structural designs to save installation space. This necessitates the precise bending of metal parts to create multi-cavity, multi-step structures, replacing traditional splicing processes and improving structural stability and anti-interference capabilities. Metal bending is a cold-working process that uses external force to plastically deform metal sheets and profiles, forming specific angles or curved surfaces. It requires no high-temperature heating and leverages the plasticity of metal to change its original shape under the action of molds or equipment to meet the assembly, structural support, or aesthetic requirements of components. It is widely used in automotive manufacturing, home appliance production, and hardware processing. Under the external force of the bending device, the metal material first undergoes elastic deformation. When the external force exceeds the material's yield strength, it enters the plastic deformation stage. By controlling the magnitude and direction of the external force and the mold shape, the metal can be precisely shaped into the target structure. However, existing automated metal bending fixtures are inconvenient to remove the bent metal from the lower mold during use. The bent metal may become embedded in the lower mold due to pressure, making it inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide an automated metal bending fixture to solve the problems mentioned in the background art, such as the inconvenience of removing the bent metal from the lower mold and the possibility that the bent metal may be embedded in the lower mold due to pressure, which makes it inconvenient to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automated metal bending fixture, comprising: a workbench, wherein a mounting plate is fixedly connected to the surface of the workbench, and a hydraulic cylinder is mounted on the surface of the mounting plate; A connecting plate is installed at the end of the hydraulic cylinder, and an upper mold is connected to the bottom of the connecting plate. Pressure plates are symmetrically installed at the bottom of the connecting plate. A lower mold is installed on the surface of the worktable, and rubber pads are symmetrically embedded in the surface of the worktable. A shock-absorbing plate is connected to the other end of the rubber pads. An auxiliary structure is provided on the surface of the worktable.

[0005] Preferably, the auxiliary structure includes: side plates symmetrically mounted on the surface of the workbench, and cylinder one symmetrically mounted on the surface of the workbench, with a push plate connected to the end of the output shaft of cylinder one, a support plate mounted on the bottom of the push plate, cylinder two mounted on the surface of the support plate, and a top plate connected to the end of cylinder two, and sliding grooves symmetrically embedded inside the side plates.

[0006] By adopting the above technical solution, the material can be limited on both sides through the auxiliary structure, and the material can be pushed out at the same time.

[0007] Preferably, the pressure plate and the shock-absorbing plate are positioned correspondingly, and the shock-absorbing plates are symmetrically installed on both sides of the lower mold.

[0008] Using the above technical solution, the pressure plate moves downward, so that the pressure plate moves to the surface of the damping plate, and pushes the damping plate downward.

[0009] Preferably, the lower mold and the upper mold are positioned correspondingly, and the side plates are symmetrically installed on both sides of the lower mold.

[0010] Using the above technical solution, the lower mold moves downward, pressing the material inside the upper and lower molds to bend the material.

[0011] Preferably, the bottom of the push plate is in contact with the surface of the side plate, and the side plate and the push plate are slidably connected.

[0012] Using the above technical solution, the cylinder pushes the push plate to move, causing the push plate to move inward on the surface of the side plate.

[0013] Preferably, the top plate is disposed inside the slide groove, and the top plate and the slide groove are slidably connected, and the side plate and the top plate are slidably connected.

[0014] Using the above technical solution, the cylinder pushes the top plate to move, causing the top plate to slide inside the slide groove.

[0015] Preferably, the surfaces of the top plate and the side plate are horizontally arranged, and the surfaces of the side plate and the lower mold are horizontally arranged.

[0016] By adopting the above technical solution, the sheet metal slides on the surface of the side plate, allowing the material to move to the surface of the lower mold side plate and the top plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This automated metal bending fixture: 1. A cylinder one, a push plate, and a cylinder two are set up. When cylinder one is started, it drives the push plate to move inward at the same time, so that the push plates on both sides limit the internal sheet material. At the same time, the bottom of the top plate is in contact with the surface of the sheet material. After the sheet material is processed, cylinder two pushes the top plate to slide upward, so that the top plate lifts the bent metal part, making it easy to remove the bent part. 2. Rubber pads, shock absorbers, and pressure plates are installed. The hydraulic cylinder drives the upper mold to move up and down to bend the parts. At this time, the hydraulic cylinder drives the pressure plate to move downward, so that the pressure plate squeezes the shock absorber. The rubber pads buffer the impact force, reduce vibration damage between the mold and the worktable, and extend the service life of the fixture. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 This utility model provides a technical solution: an automated metal bending fixture, including a workbench 10, a mounting plate 20, a hydraulic cylinder 30, a connecting plate 301, an upper die 302, a lower die 303, a rubber pad 40, a shock-absorbing plate 401, a pressure plate 402, a side plate 50, a first cylinder 501, a push plate 502, a support plate 503, a second cylinder 504, a top plate 505, and a slide 506; This automated metal bending fixture facilitates the ejection of bent parts. The specific implementation method is as follows: A mounting plate 20 is fixedly connected to the surface of the workbench 10, and a hydraulic cylinder 30 is mounted on the surface of the mounting plate 20. A connecting plate 301 is mounted at the end of the hydraulic cylinder 30, and an upper mold 302 is connected to the bottom of the connecting plate 301. A pressure plate 402 is symmetrically mounted on the bottom of the connecting plate 301. A lower mold 303 is mounted on the surface of the workbench 10, and rubber pads 40 are symmetrically embedded in the surface of the workbench 10. A shock-absorbing plate 401 is connected to the other end of the rubber pads 40. An auxiliary structure is provided on the surface of the workbench 10, including: side plates 50 symmetrically mounted on the surface of the workbench 10, and cylinders 501 symmetrically mounted on the surface of the workbench 10. A push plate 502 is connected to the end of the output shaft of cylinder 501, and a support plate 503 is mounted at the bottom of the push plate 502. Cylinder 504 is mounted on the surface of mold 3, and top plate 505 is connected to the end of cylinder 504. Slide grooves 506 are symmetrically embedded inside the side plate 50. Pressure plate 402 and damping plate 401 are positioned correspondingly, and damping plate 401 is symmetrically mounted on both sides of lower mold 303. Lower mold 303 and upper mold 302 are positioned correspondingly, and side plate 50 is symmetrically mounted on both sides of lower mold 303. The bottom of push plate 502 is in contact with the surface of side plate 50, and side plate 50 and push plate 502 are slidably connected. Top plate 505 is located inside slide groove 506, and top plate 505 and slide groove 506 are slidably connected, and side plate 50 and top plate 505 are slidably connected. The surfaces of top plate 505 and side plate 50 are horizontally positioned, and the surfaces of side plate 50 and lower mold 303 are horizontally positioned.

[0022] The material is placed on the surface of the lower mold 303 and the side plate 50. At this time, the two cylinders 501 are activated. The ends of the cylinders 501 push the push plates 502 to slide laterally along the surface of the side plate 50. When the ends of the push plates 502 on both sides are in contact with the surface of the material, the position of the material can be fixed. Simultaneously, the end of the top plate 505 is in contact with the bottom surface of the material, and... Figure 2 After the infrared sensor on the surface is fixed, it transmits an electrical signal to the control system. The control system can then activate the hydraulic cylinder 30. The end of the hydraulic cylinder 30 drives the connecting plate 301 to move downward. The connecting plate 301 drives the upper mold 302 and the pressure plate 402 to move downward. At this time, the pressure plate 402 first contacts the top surface of the damping plates 401 on both sides of the lower mold 303. As the connecting plate 301 continues to move downward, the pressure plate 402 squeezes the damping plates 401. The damping plates 401 compress the rubber pad 40 at the bottom. The rubber pad 40 buffers the pressure through elastic deformation, reducing vibration during subsequent bending. At this time, the upper mold 302 continues to move downward until it contacts the metal sheet on the surface of the lower mold 303 and continues to apply pressure. The upper mold 302 and the lower mold 303 plastically deform the sheet, completing the bending. After bending is completed, the completion of bending is detected by an infrared sensor. The infrared sensor transmits the signal to the control system, which then energizes cylinder 504, causing the end of cylinder 504 to extend. The end of cylinder 504 drives the top plate 505 to move vertically upward along the slide 506. At this time, the top plate 505 moves the material upward, lifting the bent metal product from the lower mold 303.

[0023] Working principle: When using this automated metal bending fixture, a push plate 502, a support plate 503, a cylinder 504, a top plate 505, and a slide 506 are provided to facilitate the ejection of the bent parts.
