Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to a hydraulic press blanking component. Background Art

[0002] A hydraulic press is a machine that uses the static pressure of liquid to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, sheet metal drawing, powder metallurgy, press fitting, etc.

[0003] In the prior art, the workbench of the hydraulic press is placed on a machine base, and the middle of the machine base is hollow, so there is no support in the middle of the workbench. When the machine is running, pressure is continuously applied to the pad, so the middle of the workbench is easily deformed, resulting in a short service life of the workbench, which requires frequent replacement, wasting time and resources. In addition, due to the guide column setting of the hydraulic press, when installing the mold, the space is limited and the initial installation positioning cannot be performed.

[0004] After searching, a Chinese patent with authorization announcement number CN220594184U was found, which provides a hydraulic press positioning platform, including: a hydraulic press body, an inner platform component that can slide out laterally is arranged on the corresponding bottom plate of the hydraulic press body, and the inner platform component is correspondingly spliced ​​and placed in the bottom plate, and a locking component is arranged between the bottom plate.

[0005] Although the utility model is provided with a movable inner platform component through the bottom plate, the platform is horizontally moved out to install the lower mold and improve the corresponding installation efficiency, but because the inner platform component and the bottom plate are spliced, combined with Figure 1 Therefore, the bottom plate needs to have an installation opening for splicing with the platform component. This will weaken the bottom plate's compressive resistance. After a period of time, deformation will occur at the connection between the bottom plate and the platform component, which will shorten the service life of the platform. In addition, the inner platform component is not convenient for unloading, so a hydraulic press unloading component is urgently needed to solve the above problems. Utility Model Content

[0024] See also Figure 1-3 , the embodiments of the utility model are further described;

[0025] A hydraulic press blanking assembly, comprising a workbench 1 and a hydraulic press body 7, wherein the hydraulic press body 7 is fixed above the workbench 1;

[0026] A U-shaped moving seat 6 is slidably sleeved on the workbench 1, and the moving seat 6 includes two upper and lower slide plates 61, the outer ends of the two slide plates 61 are hinged together by hinges, and the two slide plates 61 are slidably connected to the workbench 1, and a driving mechanism is installed at the bottom of the workbench 1;

[0027] Two limiting holes 8 are formed at the bottom of the lower slide plate 61, and a through hole 9 communicating with one of the limiting holes 8 is formed on the upper surface of the workbench 1 near the outer end of the movable seat 6. A lifting mechanism is installed at the bottom of the workbench 1, and the upper end of the lifting mechanism passes through the limiting hole 8 adjacent to it and then extends into the through hole 9;

[0028] Specifically, the U-shaped design of the movable seat 6 does not require a hole to be opened on the workbench 1 to meet the assembly of the movable seat 6 and the workbench 1, and does not damage the overall structure of the workbench 1. Compared with the Chinese patent with the authorization announcement number CN220594184U, the compressive strength of the workbench 1 is not weakened. The upper slide 61 is used to install a fixed mold. Before the hydraulic press body 7 is stamped, the upper slide 61 and the workbench 1 can be fixed with a clamp. The hydraulic press body 7 stamps raw materials such as plates, strips, and pipes through the mold.

[0029] like Figure 1 As shown, the driving mechanism can drive the movable seat 6 to slide outside the workbench 1, which can meet the needs of installing molds outside the hydraulic press body 7 and facilitate the installation of stamping parts on the mold.

[0030] like Figure 1-3As shown, in the initial state, the movable seat 6 is completely sleeved on the workbench 1, and the upper end of the lifting mechanism is located in the adjacent limiting hole 8 and through hole 9, which can limit the movable seat 6 laterally, which is conducive to the stable positioning of the movable seat 6 on the workbench 1, thereby facilitating stable stamping of the raw materials.

[0031] A loading frame is placed at the discharge of the moving seat 6. If the stamping part needs to be unloaded after the stamping is completed, the lifting mechanism is first started to move its output end downward. When the output end of the lifting mechanism moves out of the limiting hole 8 and the through hole 9, the lifting mechanism is closed. During this process, the clamp is removed, the positioning of the upper slide 61 is released, and then the positioning between the mold and the stamping part is released. Then the driving mechanism is started to drive the moving seat 6, the mold and the stamping part to move out of the hydraulic press body 7; when the moving seat 6 is close to the material frame, another limiting hole 8 of the lower slide 61 is aligned with the through hole 9, the driving mechanism is closed and the lifting mechanism is started. The output end of the lifting mechanism will pass through the limiting hole 8 and the through hole 9 and lift the upper slide 61, so that the stamping part in the mold can be unloaded into the material frame. Automatic unloading can be achieved by setting the driving mechanism, the lifting mechanism and the moving seat 6.

[0032] Compared with the prior art, the advantages of this application are:

[0033] 1. The U-shaped design of the movable seat 6 does not require a hole to be opened on the workbench 1 to meet the assembly of the movable seat 6 and the workbench 1, does not damage the overall structure of the workbench 1, ensures that the pressure resistance of the workbench 1 is not weakened, and can extend the service life of the workbench 1;

[0034] 2. The setting of the movable seat 6 thickens the upper surface of the workbench 1, which can enhance the pressure resistance of the workbench 1;

[0035] 3. The lifting mechanism can not only limit the movable seat 6 and enhance the stability of the movable seat 6 on the workbench 1, but also when unloading, the driving mechanism can drive the movable seat 6 to move outward, and then the lifting mechanism can lift the slide plate 61 above the movable seat 6 upward to realize automatic unloading.

[0036] The driving mechanism is provided with at least one, the driving mechanism comprises an electric guide rail 2 and a movable leg 3, the electric guide rail 2 is fixed to the bottom of the workbench 1, and the movable leg 3 is installed between the electric guide rail 2 and the slide plate 61 below;

[0037] Specifically, when the driving mechanism is used, the electric guide rail 2 is connected to a power source, and the electric guide rail 2 drives the movable legs 3 and the movable seat 6 to move laterally together.

[0038] The lifting mechanism includes an electric lifting rod 4 and a deformable fitting member 5. The electric lifting rod 4 is fixed to the bottom of the workbench 1, and the output end of the electric lifting rod 4 passes through a limit hole 8 adjacent thereto and then extends into a through hole 9. The deformable fitting member 5 is fixed at the output end of the electric lifting rod 4.

[0039] Specifically, when the lifting mechanism is needed to lift the upper skateboard 61, the electric lifting rod 4 is connected to the power supply, the electric lifting rod 4 will drive the deformable fitting part 5 to move upward, and the deformable fitting part 5 will pass through the limiting hole 8 and the through hole 9 in turn and then fit with the bottom of the upper skateboard 61. As the electric lifting rod 4 continues to move upward, since the outer ends of the two skateboards 61 are hinged together by hinges, the electric lifting rod 4 will drive the deformable fitting part 5 to lift the upper skateboard 61 upward, so that the stamping part falls into the material frame, and the unloading is completed.

[0040] The deformable fitting member 5 includes a support plate 51, a spring 52 and a spring shaft 53. The support plate 51 is provided with two upper and lower parts. The spring shaft 53 is fixed to the center of the upper surface of the lower support plate 51, and the movable end of the spring shaft 53 is hinged to the center of the lower surface of the lower support plate 51. The spring 52 is provided with a plurality of springs and is fixed between the two support plates 51.

[0041] Specifically, during the upward movement of the deformable fitting part 5, the upper support plate 51 will contact the upper slide plate 61. When the upper slide plate 61 is lifted up, the upper support plate 51 will be subjected to the pressure of the upper slide plate 61. The upper support plate 51 will transfer the pressure to the spring shaft 53 and the plurality of springs 52. At this time, the spring shaft 53 and the plurality of springs 52 will undergo elastic deformation to ensure that the upper support plate 51 is always in contact with the upper slide plate 61, so that the upper slide plate 61 is stably lifted up and stable material discharge is achieved.
