Description

Technical Field

[0001] This application relates to the field of CNC hydraulic bending machine technology, and in particular to a safety guard for a CNC hydraulic bending machine used in wind turbine components. Background Technology

[0002] CNC hydraulic bending machines are key equipment in the metal processing field, widely used to precisely bend metal sheets into specific shapes. They integrate mechanical, hydraulic, electrical, and CNC technologies and mainly consist of a frame, hydraulic system, mold, slider, worktable, CNC system, and back gauge device. During operation, the CNC system generates instructions to start the hydraulic pump, which drives the slider to move the upper mold to press down on the sheet metal, causing it to plastically deform under the action of the mold and complete the bending. It can achieve high-precision, high-efficiency, and diversified bending processing.

[0003] However, during the operation of CNC hydraulic bending machines, it is difficult to protect the area in front of the punching zone. When workers' fingers are close to the punching area, they are prone to getting their hands caught. In addition, the flying metal fragments during the processing can cause injury to the workers. Therefore, in order to solve the above problems, we provide a safety guard for CNC hydraulic bending machines for wind turbine parts. Utility Model Content

[0004] The purpose of this utility model is to provide a safety cover for a CNC hydraulic bending machine for wind turbine components, so as to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions: A safety cover for a CNC hydraulic bending machine for wind turbine components includes an outer protective cover, an inner protective cover slidably connected to the inner wall of the outer protective cover, a support platform below the inner protective cover, support seats fixedly connected to both sides of the support platform, sliding holes formed on the adjacent sides of the two support seats, connecting sliders slidably connected to the inner walls of the two sliding holes, and the adjacent sides of the two connecting sliders fixedly connected to the outer surface of the outer protective cover, a lifting plate fixedly connected to the adjacent sides of the two connecting sliders, and a bending upper die fixedly installed on the bottom surface of the lifting plate.

[0006] Preferably, the inner top wall of the protective cover is fixedly connected to two sets of springs, and the bottom ends of the two sets of springs are jointly fixedly connected to two connecting plates, the bottom surfaces of the two connecting plates being fixedly connected to the top of the protective inner cover.

[0007] Preferably, the outer surface of the protective inner cover is fixedly connected to two limiting blocks, and the outer surface of the protective outer cover is provided with two limiting holes. The ends of the two limiting blocks that are far apart from each other extend into the interior of the two limiting holes, and the outer surface of the limiting blocks is slidably connected to the inner wall of the limiting holes.

[0008] Preferably, each of the two support seats is fixedly connected to a connecting seat at its top end, and each of the two connecting seats has two threaded connecting grooves on its upper surface.

[0009] Preferably, the bottom surfaces of both support bases are fixedly connected to a fixed base, and the upper surfaces of both fixed bases are provided with fixing holes.

[0010] Preferably, an arc-shaped rubber buffer pad is fixedly connected to the bottom surface of the inner protective cover, and both the inner and outer protective covers are located in front of the bending upper die.

[0011] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: 1. The safety guard of the CNC hydraulic bending machine for wind turbine components uses a lifting plate to drive the bending upper die downward. This allows the outer guard to slide down synchronously with the connecting slider and be positioned in front of the bending upper die along with the inner guard. This directly isolates the stamping area from the operator, preventing finger pinching accidents caused by workers' fingers approaching the stamping area. It can also intercept metal fragments that fly during processing, preventing them from injuring workers' eyes or skin and reducing safety hazards in traditional processing.

[0012] 2. The safety guard of the CNC hydraulic bending machine used for this wind turbine component completes the bending and upward reset through the upper bending die. This allows the connecting slider to drive the outer and inner protective covers to move upward synchronously, which can fully expose the stamping area. This makes it convenient for workers to quickly unload the processed workpiece without disassembling or adjusting the protective structure, saving operation time. At the same time, when loading, the material to be processed can be placed directly in the open space after the protective structure is raised, ensuring the convenience of operation before and after each processing.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-5 This utility model provides a technical solution for a safety guard for a CNC hydraulic bending machine used in wind turbine components: A safety guard for a CNC hydraulic bending machine for wind turbine components includes an outer protective cover 1, an inner protective cover 2 slidably connected to the inner wall of the outer protective cover 1, a support platform 8 below the inner protective cover 2, support seats 3 fixedly connected to both sides of the support platform 8, sliding holes 4 on the adjacent sides of the two support seats 3, connecting sliders 5 slidably connected to the inner walls of the two sliding holes 4, the adjacent sides of the two connecting sliders 5 fixedly connected to the outer surface of the inner protective cover 2, and a lifting plate 6 fixedly connected to the adjacent sides of the two connecting sliders 5. The lifting plate 6 requires hydraulic... The pressure drive system is connected, and the bottom surface of the lifting plate 6 is fixedly installed with the bending upper die 7. Specifically, the protective outer cover 1 can form a protective barrier with the inner protective cover 2 inside, isolating the operator from direct contact with the stamping area. Through the setting of the sliding hole 4, a sliding track can be provided for the connecting slider 5. One end of the connecting slider 5 is connected to the inner protective cover 2, and the other end is fixed to the lifting plate 6, realizing the linkage between the bending action and the protective action. When the lifting plate 6 drives the bending upper die 7 to perform bending operations downward, it can drive the inner protective cover 2 to slide down, so that the protective structure always moves with the stamping area to ensure the protective effect.

[0018] In this embodiment, two sets of springs 10 are fixedly connected to the inner top wall of the protective outer cover 1. The bottom ends of the two sets of springs 10 are fixedly connected to two connecting plates 9. The bottom surfaces of the two connecting plates 9 are fixedly connected to the top of the protective inner cover 2. Two limiting blocks 12 are fixedly connected to the outer surface of the protective inner cover 2. Two limiting holes 11 are opened on the outer surface of the protective outer cover 1. The ends of the two limiting blocks 12 that are far apart from each other extend into the interior of the two limiting holes 11, and the outer surface of the limiting blocks 12 is slidably connected to the inner wall of the limiting holes 11. Specifically, the springs 10 inside the protective outer cover 1, in cooperation with the connecting plates 9, provide buffering force when the protective inner cover 2 slides down, preventing it from rapidly impacting the support platform 8 due to gravity or transmission inertia. At the same time, when the bending upper die 7 is reset, it helps the protective inner cover 2 to rise smoothly. Through the sliding cooperation between the limiting blocks 12 and the limiting holes 11, the lifting stroke of the protective inner cover 2 can be limited, preventing it from detaching from the protective outer cover 1.

[0019] In this embodiment, each of the two support bases 3 has a connecting base 15 fixedly connected to its top. Each of the two connecting bases 15 has two threaded connecting grooves 16 on its upper surface. Each of the two support bases 3 has a fixed base 13 fixedly connected to its bottom surface. Each of the two fixed bases 13 has a fixing hole 14 on its upper surface. An arc-shaped rubber buffer pad 17 is fixedly connected to the bottom surface of the protective inner cover 2. Both the protective inner cover 2 and the protective outer cover 1 are located in front of the bending upper die 7. Specifically, the connecting base 15 and the threaded connecting groove 16 can be used to assist in fixing the protective cover to the body of the CNC hydraulic bending machine, thereby enhancing the connection stability between the protective cover and the equipment. The fixed base 13 and the fixing hole 14 can be used to firmly fix the protective cover with fasteners such as bolts, preventing positional displacement due to vibration during processing. The arc-shaped rubber buffer pad 17 on the bottom surface of the protective inner cover 2 can further reduce the impact of the protective inner cover 2 on the support table 8 or the workpiece when it descends, protecting the components and the workpiece from damage.

[0020] Working principle: First, when the hydraulic system drives the lifting plate 6 to move the bending upper die 7 downward, the protective cover 1 will also slide down synchronously with the connecting slider 5. Since the protective inner cover 2 and the protective outer cover 1 are located in front of the bending upper die 7, they can directly block the stamping area. At the same time, the spring 10 inside the protective outer cover 1 forms a buffer support for the protective inner cover 2 through the connecting plate 9, preventing it from sliding down and colliding with the support platform 8. It can buffer it. Then, the protective outer cover 1 and the protective inner cover 2 block and protect the stamping area. When the bending upper die 7 completes the bending and resets upward, the connecting slider 5 can drive the protective outer cover 1 and the protective inner cover 2 to move upward, which is convenient for unloading the workpiece and subsequent loading.

[0021] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
