Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal shell manufacturing technology, specifically a refrigerator sheet metal shell manufacturing device. Background Technology
[0002] In the refrigerator manufacturing industry, sheet metal shells are the core structural components of refrigerators.

However, the waste generated after punching will still remain on the surface of the workbench. If the residual waste is not cleaned in time, it will affect the subsequent processing of the sheet metal shell, resulting in poor overall practicality.

[0026] 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.
[0027] Example
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a refrigerator sheet metal shell manufacturing device, including a frame 1, a workbench 2 fixed at the top of the frame 1, a protective frame 3 set at the middle of the top of the workbench 2, slots on both sides of the bottom of the protective frame 3, and a sliding groove 4 opened on one side of the top of the workbench 2.
[0029] A guide rod 5 passes through the inner side of the slide 4, and a first spring 6 is sleeved on the outer ring of one end of the guide rod 5. The other end of the first spring 6 is fixedly connected to a slider 7, and a push rod 8 is rotatably connected to the top of the slider 7. A hole with a diameter that matches the outer diameter of the guide rod 5 is opened on the inner side of the slider 7. The other end of the push rod 8 is connected to a lifting plate 9, and a linkage rod 10 is rotatably connected to one side of the bottom of the lifting plate 9. A slot is opened in the middle section of the lifting plate 9. The two ends of the linkage rod 10 are rotatably connected to one side of the bottom of the lifting plate 9 and the inner side wall of the worktable 2 through connecting ears. A rubber pad 11 is provided on the upper surface of the lifting plate 9, and the rubber pad 11 is equidistantly distributed along one side of the top of the lifting plate 9.
[0030] In use, the refrigerator sheet metal parts to be processed are placed on the upper surface of the lifting plate 9 beforehand. After placement, when punching is performed on the refrigerator sheet metal parts, the lifting plate 9 will move longitudinally as the structure is pressed down. At this time, as the lifting plate 9 moves longitudinally, the linkage rod 10, which is rotatably connected to one side of its bottom via a connecting ear, will rotate along the inner wall of the worktable 2. Meanwhile, the push rod 8, which is rotatably connected to the other side of the bottom of the lifting plate 9, will push the slider 7, which is rotatably connected to its other end. At this time, the slider 7 will slide laterally along the guide rod 5 under the pushing action of the push rod 8. During the sliding process, the first spring 6 will deform and generate a reverse force. When the lifting plate 9 moves longitudinally, the sliding plate 9 will move longitudinally. When the longitudinal movement of plate 9 comes into contact with the surface of worktable 2, it stops moving, which facilitates the subsequent processing of the refrigerator sheet metal parts with the processing structure. After processing is completed, the longitudinal pressure applied to the lifting plate 9 disappears. At this time, the reverse force generated by the deformation of the first spring 6 will push the slider 7 in the opposite direction, so that it will be horizontally reset along the guide rod 5. The reverse movement of the slider 7 will cause the push rod 8 to push the lifting plate 9 in the opposite direction, thereby causing the lifting plate 9 to drive the processed sheet metal parts to be longitudinally reset. The slot opened in the middle of the bottom end of the lifting plate 9 can separate the waste material from the sheet metal parts, preventing the waste material from remaining on the surface of the sheet metal parts after subsequent processing, which would affect the further processing of the sheet metal parts.
[0031] like Figure 1 and Figure 2 As shown, in some embodiments, a hydraulic cylinder 12 is fixedly provided at the top center of the protective frame 3, and a lifting seat 13 is fixedly provided at the bottom of the hydraulic cylinder 12. A punching structure 14 is installed at the bottom of the lifting seat 13, and a vertical rod 15 is fixedly provided on one side of the top of the lifting seat 13. The vertical rod 15 is symmetrically distributed along the vertical center line of the lifting seat 13.
[0032] When in use, after the refrigerator sheet metal part to be punched is placed, the hydraulic cylinder 12 pushes the lifting seat 13 fixedly connected to its bottom longitudinally. The longitudinal movement of the lifting seat 13 drives the punching structure 14 installed at its bottom to move longitudinally as well, so that the subsequent work of the punching structure 14 can be used to punch the refrigerator sheet metal part. As the lifting seat 13 moves longitudinally, the vertical rod 15 will move longitudinally along the hole opened at the top of the protective frame 3, thereby improving the stability of the lifting seat 13 during the longitudinal movement.
[0033] like Figure 5 and Figure 6 As shown, in some embodiments, a drive motor 16 is fixedly mounted on one end surface of the workbench 2, and the output end of the drive motor 16 is connected to a bidirectional screw 17. Both ends of the bidirectional screw 17 are provided with external threads, and the external threads on both sides are arranged in opposite directions. A threaded sleeve 18 is fitted on the outer surface of the bidirectional screw 17, and a movable seat 19 is fixedly mounted on the top of the threaded sleeve 18. The movable seats 19 are symmetrically distributed along the vertical center line of the workbench 2, and the width of the movable seats 19 is adapted to the width of the slots opened on both sides of the bottom of the protective frame 3. The platform size formed when the two movable seats 19 are in contact with each other is adapted to the size of the slot opened in the middle of the lifting plate 9.
[0034] In use, when it is necessary to achieve the opposite movement of the two movable seats 19, the drive motor 16 works to make the bidirectional screw 17 connected to its output end rotate accordingly. Since the bidirectional screw 17 and the threaded sleeve 18 form a threaded connection, and the threads on the outer surfaces of the two ends of the bidirectional screw 17 are set in opposite directions, the rotation of the bidirectional screw 17 can realize the opposite movement of the two threaded sleeves 18, and then the opposite movement of the threaded sleeves 18 can realize the synchronous movement of the two movable seats 19.
[0035] like Figure 6 As shown, in some embodiments, a flip plate 20 is rotatably connected to the inner side of the top of the movable seat 19, and a second spring 21 is fixedly connected to one bottom side of one end of the flip plate 20. The flip plate 20 is rotatably connected to the movable seat 19 through a bearing seat. The second spring 21 is equidistantly distributed along the bottom of one end of the flip plate 20, and the two ends of the second spring 21 are respectively fixedly connected to the bottom of one end of the flip plate 20 and the upper surface of one end of the movable seat 19. A protrusion 22 is provided in the middle section of the bottom of one end of the flip plate 20.
[0036] When in use, when the pressure applied to the flip plate 20 is removed, the reverse force generated by the deformation of the second spring 21 can easily push the flip plate 20 in the reverse direction. At this time, one end of the flip plate 20 rotates around the moving seat 19 through the shaft, thereby making the flip plate 20 tilted. This facilitates the movement of the waste material remaining on the surface of the flip plate 20 along the surface of the flip plate 20 and discharges it through the slot opened on one side of the bottom of the protective frame 3, which facilitates the centralized processing of the waste material. The protrusion 22 can provide support for the subsequent punching when the flip plate 20 and the moving seat 19 are horizontally aligned.
[0037] like Figure 4 As shown, in some embodiments, the slider 7 is slidably connected to the guide rod 5 via the first spring 6, and one end of the push rod 8 is rotatably connected to the slider 7 via a connecting lug.
[0038] When in use, the reverse force generated by the deformation of the first spring 6 pushes the slider 7 laterally, causing it to move laterally along the guide rod 5. As the slider 7 moves laterally, the push rod 8, which is rotatably connected to its top, also rotates accordingly.
[0039] like Figure 5 As shown, in some embodiments, the inner side of the threaded sleeve 18 is provided with a threaded hole whose diameter is adapted to the outer diameter of the bidirectional screw 17, and the threaded sleeve 18 and the bidirectional screw 17 are connected by a thread through the threaded hole.
[0040] In use, the threaded connection between the threaded sleeve 18 and the double-acting screw 17 facilitates the lateral movement of the threaded sleeve 18 when the double-acting screw 17 rotates.
[0041] In summary, the refrigerator sheet metal parts to be processed are placed on the upper surface of the lifting plate 9 beforehand. Then, the hydraulic cylinder 12 longitudinally pushes the lifting seat 13, realizing the longitudinal movement of the punching structure 14. This facilitates subsequent punching of the refrigerator sheet metal parts using the punching structure 14. As the punching structure 14 presses down, the lifting plate 9 also moves longitudinally. At this time, the linkage rod 10 rotates along the inner wall of the worktable 2, while the push rod 8 pushes the slider 7, causing it to slide laterally along the guide rod 5. This causes the first spring 6 to deform and generate a reverse force. The lifting plate 9 stops moving when it contacts the surface of the worktable 2, facilitating subsequent processing of the refrigerator sheet metal parts using the provided processing structure. Once processing is complete... Afterwards, the longitudinal pressure applied to the lifting plate 9 disappears. At this time, the reverse force generated by the deformation of the first spring 6 will push the slider 7 in the opposite direction, causing it to be horizontally reset along the guide rod 5. Under the reverse movement of the slider 7, the push rod 8 will push the lifting plate 9 in the opposite direction, thereby causing the lifting plate 9 to drive the processed sheet metal parts to be longitudinally reset. The waste material can be separated from the sheet metal parts through the slot opened in the middle of the bottom end of the lifting plate 9. Then, the drive motor 16 works to make the bidirectional screw 17 rotate. The rotation of the bidirectional screw 17 can realize the opposite movement of the threaded sleeves 18 on both sides. The opposite movement of the threaded sleeves 18 can realize the synchronous movement of the two moving seats 19. After the moving seats 19 move to the designated position, the waste material remaining on their surface can be discharged by the inclined flip plate 20.
[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
