Description

Technical Field

[0001] This utility model relates to the field of electrical appliance enclosure processing, specifically a metal plate straightening device for electrical appliance enclosure processing. Background Technology

[0002] The outer shell of the electrical control cabinet is made of metal plates welded and assembled. Before entering the factory for processing, the metal plates are wound in a roll on a metal drum. Straightening equipment is needed to straighten the curved metal plates after they are unwound. If the straightening of the metal plate roll cannot achieve complete flatness of the metal plate, it may result in the metal plates cut by the subsequent shearing equipment having different sizes and uneven flatness.

[0003] In the prior art, such as in publication number CN210475054U, a straightening device for metal plates used in the processing of electrical control cabinets is disclosed. It includes a frame and a straightening chamber located at the upper end of the frame. A metal plate coil is disposed on one side of the frame and mounted on a rotating frame. The inner cavity of the straightening chamber is equipped with a hydraulic straightening assembly and a roller straightening device. The roller straightening device includes a straightening roller and a bottom roller rotatably mounted in the lower part of the inner cavity of the straightening chamber, with the bottom roller located directly below the straightening roller. This invention is particularly suitable for the precise straightening of metal plates used in the processing of electrical control cabinet shells, and has high social value and application prospects.

[0004] While the aforementioned patents can precisely straighten metal plates through hydraulic straightening and roller straightening, they cannot flexibly adjust the diameter between the rollers according to the thickness of the steel plate, thus failing to meet the straightening requirements of steel plates of different thicknesses. Furthermore, manually placing the steel plate into the straightening device poses a certain risk, potentially causing workers' hands to get caught and creating a safety threat. Therefore, to address the above issues, a metal plate straightening device for electrical enclosure processing is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, such as the inability to flexibly adjust the diameter between pressure rollers according to the thickness of the steel plate, and the inability to adapt to the straightening requirements of steel plates of different thicknesses; at the same time, manually placing the steel plate into the straightening device is dangerous and may cause workers' hands to get caught, posing a safety threat. This utility model proposes a metal plate straightening device for processing electrical enclosures.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The metal plate straightening device for processing electrical cabinets according to this utility model includes a processing table. The top surface of the processing table is axially symmetrically connected to a lower side plate. The side of the lower side plate is fixedly connected to a lifting component. One end of the lifting component is provided with an upper side plate. The sides of both the lower and upper side plates are rotatably connected to pressure rollers. One end of the pressure roller is fixedly connected to the output end of a drive motor. The top surface of the processing table is axially symmetrically provided with a groove. A moving component is fixedly connected inside the groove. An equipment box is fixedly connected to the side of the processing table. A controller is sleeved inside the equipment box.

[0007] The lifting assembly includes a servo motor fixedly connected to the side of the lower side plate, a lead screw fixedly connected to the output end of the servo motor, a slider threadedly connected to the surface of the lead screw, a slide groove fixedly connected to the side of the lower side plate, and the slider slidably connected inside the slide groove and fixedly connected to the upper side plate.

[0008] The moving component includes a horizontal electric push rod fixedly connected to the bottom wall of the groove. One end of the horizontal electric push rod is fixedly connected to a connecting block. An electric telescopic rod is fixedly connected to the top surface of the connecting block. A bracket is fixedly connected to the top end of the electric telescopic rod. A sleeve hole is opened on the surface of the bracket, and the infrared sensor is sleeved inside the sleeve hole.

[0009] Preferably, there are multiple drive motors, which are fixedly connected to the outer sides of the lower side plate and the upper side plate respectively, and the output end of each drive motor is coaxially connected to the corresponding pressure roller.

[0010] Preferably, the longitudinal axis of the groove is parallel to the axis of the lead screw, and the sliding trajectory of the slider coincides with the extension direction of the groove.

[0011] Preferably, the infrared sensor is electrically connected to the controller via a signal line, and the controller is connected to the servo motor's lateral electric push rod and electric telescopic rod respectively.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses a servo motor in the lifting assembly to drive the lead screw to rotate, which in turn drives the threaded slider to move vertically along the slide groove, thereby adjusting the distance between the upper and lower side plates. This allows the gap between the upper and lower pressure rollers to be flexibly adjusted according to steel plates of different thicknesses, solving the problem that the existing technology cannot adapt to the straightening of steel plates of multiple specifications and improving the adaptability of the equipment.

[0016] 2. In this utility model, after the infrared sensor in the moving component detects the position of the steel plate, the controller controls the horizontal electric push rod and the electric telescopic rod to automatically and accurately feed the steel plate on the support between the upper and lower pressure rollers, avoiding the risk of the hand getting caught in the pressure roller when feeding manually, and realizing safe and automated operation.

[0023] 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 scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, a metal plate straightening device for processing electrical enclosures includes a processing table 1. A lower side plate 2 is fixedly connected to the top surface of the processing table 1 in an axisymmetric manner. A lifting component 3 is fixedly connected to the side of the lower side plate 2. An upper side plate 4 is provided at one end of the lifting component 3. Pressure rollers 5 are rotatably connected to the sides of both the lower side plate 2 and the upper side plate 4. One end of the pressure roller 5 is fixedly connected to the output end of a drive motor 6. A groove is provided in an axisymmetric manner on the top surface of the processing table 1. A moving component 7 is fixedly connected inside the groove. An equipment box 8 is fixedly connected to the side of the processing table 1. A controller 9 is sleeved inside the equipment box 8. The lifting component 3 includes a servo motor 31 fixedly connected to the side of the lower side plate 2. A lead screw 32 is fixedly connected to the output end of the servo motor 31. A slider 33 is threadedly connected to the surface of the lead screw 32. A slide groove 34 is fixedly connected to the side of the lower side plate 2. The slider 33 is slidably connected inside the slide groove 34 and the upper side plate 4 is fixedly connected to its side.

[0025] During operation, the servo motor 31 of the lifting component 3 drives the lead screw 32 to rotate, causing the threaded slider 33 to move vertically along the groove 34 on the side of the lower side plate 2, which in turn drives the upper side plate 4 to rise and fall synchronously, thereby adjusting the gap between the pressure rollers 5 between the lower side plate 2 and the upper side plate 4. When the metal plate is placed on the bracket 74 of the moving component 7, the infrared sensor 75 of model E3F-2B4 detects the signal and transmits it to the controller 9 in the equipment box 8. The controller 9 of model S7-200 triggers the electric telescopic rod 73 to lift the bracket 74 to the center height of the pressure roller 5. Then, the transverse electric push rod 71 pushes the connecting block 72 to move laterally, accurately feeding the metal plate between the upper and lower pressure rollers 5. The drive motor 6 drives the pressure roller 5 to rotate to complete the straightening.

[0026] Furthermore, the moving component 7 includes a transverse electric push rod 71 fixedly connected to the bottom wall of the groove. One end of the transverse electric push rod 71 is fixedly connected to a connecting block 72. The top surface of the connecting block 72 is fixedly connected to an electric telescopic rod 73. The top end of the electric telescopic rod 73 is fixedly connected to a bracket 74. A sleeve hole is opened on the surface of the bracket 74, and an infrared sensor 75 is sleeved inside the sleeve hole.

[0027] During operation, the controller 9 coordinates the linkage of the servo motor 31, the transverse electric push rod 71, and the electric telescopic rod 73 to achieve synchronous control of automatic metal plate feeding and pressure roller 5 gap adjustment: when the infrared sensor 75 detects the placement of the metal plate, the electric telescopic rod 73 first raises the support 74 to the center line of the pressure roller 5, and the transverse electric push rod 71 then pushes the support 74 to move laterally to the inlet of the pressure roller 5. At the same time, the servo motor 31 adjusts the height of the upper side plate 4 according to the preset thickness parameters, so that the metal plate passes through stably under the clamping of the pressure roller 5, and completes thickness adaptive straightening.

[0028] Furthermore, the longitudinal axis of the slide groove 34 is set parallel to the axis of the lead screw 32, and the sliding trajectory of the slider 33 coincides with the extension direction of the slide groove 34.

[0029] During operation, when the servo motor 31 drives the lead screw 32 to rotate, the threaded slider 33 moves vertically along the extension direction of the slide groove 34. The slide groove 34 rigidly limits the sliding trajectory of the slider 33 to ensure that the upper side plate 4 does not deviate during the lifting and lowering process. This structure, through the axial consistency design of the slide groove 34 and the lead screw 32, makes the slider 33 move stably when adjusting the gap of the pressure roller 5, avoiding the radial swing caused by the rotation of the lead screw 32, which leads to the misalignment of the pressure roller 5. This allows for precise control of the clamping pressure of the upper and lower pressure rollers 5, adapting to the straightening requirements of metal plates of different thicknesses.

[0030] Furthermore, the extension and retraction direction of the transverse electric push rod 71 is perpendicular to the axis of the pressure roller 5, and the lifting and lowering direction of the electric telescopic rod 73 is perpendicular to the top surface of the processing table 1.

[0031] During operation, when the infrared sensor 75 (model E3F-2B4) detects that the metal plate is placed on the surface of the support 74, the controller 9 controls the electric telescopic rod 73 to vertically lift the support 74 to the center height of the pressure roller 5. Then, the transverse electric push rod 71 pushes the connecting block 72 horizontally in a direction perpendicular to the axis of the pressure roller 5, so that the metal plate accurately enters the straightening area between the upper and lower pressure rollers 5. This bidirectional motion design, through the coordinated action of vertical lifting and horizontal pushing, ensures that the metal plate always remains orthogonal to the axis of the pressure roller 5 during the feeding process, avoiding feeding jams or uneven straightening due to tilting or offset, while reducing the risk of manual intervention.

[0032] Working principle: When the metal plate is placed on the surface of the support 74 of the moving component 7, the infrared sensor 75 detects the signal and triggers the controller 9 to start the electric telescopic rod 73 to vertically lift the support 74 to the center height between the upper and lower pressure rollers 5. Then, the transverse electric push rod 71 pushes the connecting block 72 horizontally in a direction perpendicular to the axis of the pressure roller 5, sending the metal plate into the clamping area of ​​the pressure roller 5. At the same time, the servo motor 31 of the lifting component 3 drives the lead screw 32 to rotate, so that the threaded slider 33 moves vertically along the slide groove 34, driving the upper side plate 4 to rise and fall to adjust the gap of the pressure roller 5. The drive motor 6 drives the upper and lower pressure rollers 5 to rotate in the same direction. The metal plate is straightened under the crushing and traction of the pressure roller 5.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
