Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic punching, in particular to a numerically controlled hydraulic punching device for a water retaining plate of an air-conditioning unit. Background Art
[0002] The water retaining plate of the air conditioning unit is a component installed inside the air conditioning system. It is mainly used to prevent condensation or other moisture from being blown into the indoor or outdoor environment by the fan, so as to keep the air conditioning system dry and running efficiently. In the production line of the water retaining plate, punching is required to form the necessary holes, drainage grooves or other features.
[0003] During the operation of the existing punching device, when external forces act on the water baffle, such as punching pressure, stress will be distributed on the water baffle. If the water baffle lacks proper support, its edges, especially the four corners, will experience higher stress concentration than the central area. In these high-stress areas, the material's tendency to plastic deformation increases, making the four corners of the water baffle more prone to warping, bending or concave. Therefore, the present application provides a CNC hydraulic punching device for the water baffle of an air-conditioning unit to meet the needs. Utility Model Content

DETAILED DESCRIPTION
[0026] The following is a detailed description of a polymer material injection molding device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.
[0027] like Figure 1 , Figure 2 and Figure 4As shown, an embodiment of the utility model provides a CNC hydraulic punching device for a water baffle of an air-conditioning unit, comprising: a workbench 1; two movable parts 5, which are arranged on the workbench 1; a first clamping plate 7, which is slidably arranged on the movable part 5; a second clamping plate 8, which is arranged on the movable part 5, and the first clamping plate 7 and the second clamping plate 8 are symmetrical; the first clamping plate 7 and the second clamping plate 8 are U-shaped; the second clamping plate 8 comprises: a support bar 81, which is arranged on the movable part 5; a pad bar 82, which is arranged between the support bars 81, and the bottom surface of the pad bar 82 is flush with the bottom surface of the support bar 81, and the thickness of the pad bar 82 is less than the thickness of the support bar 81.
[0028] By setting the first clamping plate 7 and the second clamping plate 8, the structures of the two are the same. The first clamping plate 7 cooperates with the second clamping plate 8 to fix and position the water baffle body 6, which can effectively wrap the edge of the water baffle body 6, provide all-round support, enhance the rigidity of the water baffle edge, and reduce stress concentration.
[0029] like Figure 2 , Figure 4 and Figure 5 As shown, it also includes: a first buffer rib 83, which is arranged on the inner wall of the support bar 81; a second buffer rib 84, which is arranged on the inner wall of the support bar 81; a third buffer rib 85, which is arranged on the inner wall of the support bar 81; the first buffer rib 83, the second buffer rib 84 and the third buffer rib 85 are not located on the same inner wall; and one end of the first buffer rib 83, one end of the second buffer rib 84 and one end of the third buffer rib 85 are connected to each other, and the other end of the first buffer rib 83, the other end of the second buffer rib 84 and the other end of the third buffer rib 85 are respectively connected to different inner wall surfaces of the support bar 81; a buffer bar 86 is arranged in the support bar 81, and the two sides of the buffer bar 86 are respectively connected to two inner walls parallel to the support bar 81.
[0030] By providing the first buffer rib 83, the second buffer rib 84 and the third buffer rib 85, the impact force applied by the punching head 4 to the water baffle body 6 is dispersed over a larger area instead of being concentrated on one point or one surface; the stress concentration in a specific area of the water baffle body 6 can be significantly reduced, and the material can be prevented from plastically deforming or rupturing around the punching point; when one side of the support bar 81 is impacted, the buffer bar 86 contacts the other inner wall of the support bar 81 through its elastic deformation, further dispersing and absorbing the impact force, and reducing the direct impact on the water baffle body 6; it also helps to reduce noise and vibration during the punching process.
[0031] like Figure 1As shown, the hydraulic punching machine 3 is arranged on the workbench 1; the punching head 4 is arranged on the hydraulic punching machine 3. The core purpose of setting the hydraulic punching machine 3 is to realize automatic and high-precision punching operation, improve production efficiency and processing quality. It provides powerful power through the hydraulic system to ensure that the punching process is stable and controllable, which is the existing technology.
[0032] like Figure 1 As shown, the punching head 4 is stepped. By setting the punching head 4, the design is stepped, which can achieve multi-stage punching, gradually increase the punching depth, significantly reduce the deformation of the material, improve the punching accuracy, and also reduce the wear of the punching tool and extend the tool life.
[0033] like Figure 1 As shown, it also includes: an infrared sensor 2, which is movably arranged below the punching head 4. By setting the infrared sensor 2, an electric telescopic rod is arranged in the hydraulic punching machine 3, and the electric telescopic rod is connected to the infrared sensor 2 to control the movement of the infrared sensor 2, monitor the position and state of the water retaining plate body 6 during the punching process, ensure the relative position of the punching head 4 and the water retaining plate body 6 is accurate, and prevent the punching from deviating from the predetermined position.
[0034] like Figure 1 and Figure 5 As shown, it also includes: a buffer strip 86 made of elastic material, and the buffer strip 86 is wavy; the water baffle body 6 is arranged between the first clamping plate 7 and the second clamping plate 8. By arranging the buffer strip 86, the impact force of the punching head 4 on the water baffle body 6 when punching is absorbed and dispersed, and the deformation of the water baffle body 6 is reduced.
[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the moving part 5 includes: a moving frame 51, which is arranged on the workbench 1; a stepping motor 52, which is arranged on the top of the moving frame 51; a screw rod 53, which is arranged in the moving frame 51; a sliding block 54, which is threadedly sleeved on the screw rod 53, and the inner side of the sliding block 54 is connected to the first clamping plate 7.
[0036] By setting the sliding block 54 and fixing the sliding block 54 and the first clamping plate 7 together, the rotational motion of the screw rod 53 is converted into the linear motion of the first clamping plate 7, so as to realize the lifting and lowering of the first clamping plate 7, thereby clamping and releasing the water retaining plate body 6.
[0037] like Figure 3As shown, the top of the screw rod 53 passes through the moving frame 51 and is connected to the output end of the stepper motor 52. By setting the stepper motor 52, the output end of the stepper motor 52 and the screw rod 53 are fixed. When the stepper motor 52 is operated by an external current, the output end of the stepper motor 52 generates a rotating power, which drives the screw rod 53 to generate synchronous motion, providing a power source for the rotation of the screw rod 53.
[0038] The technical solution provided by the utility model uses an external controller to start the stepper motor 52 to drive the screw rod 53 to rotate forward, so that the sliding block 54 moves upward, drives the first clamping plate 7 to rise, and places the water baffle body 6 on the second clamping plate 8, so that the water baffle body 6 is located on the top of the pad strip 82, and the edge of the water baffle body 6 contacts the support strip 81. The stepper motor 52 runs, drives the screw rod 53 to reverse, so that the sliding block 54 moves downward, drives the first clamping plate 7 to descend, and clamps and fixes the water baffle body 6; the hydraulic punching machine 3 is started, and the punching head 4 starts to punch holes according to the preset program. Industry; during the punching process, when the punching head 4 contacts the water baffle body 6, the cushion strip 82 reduces the impact on the water baffle body 6, and at the same time, the impact force is dispersed to the second buffer rib 84 and the third buffer rib 85 through the first buffer rib 83, so that the impact force originally concentrated on a single surface of the support bar 81 is transferred to multiple surfaces, thereby reducing local stress concentration; when a single surface of the support bar 81 is impacted, the buffer bar 86 is driven to bend, and the buffer bar 86 contacts the other inner wall of the support bar 81 when bending, thereby dispersing the impact force. After the punching is completed, the stepper motor 52 repeats the above operation to take out the water baffle body 6.
[0039] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
