Description

Technical Field

[0001] This utility model belongs to the field of server chassis processing technology, specifically relating to a sheet metal bending device. Background Technology

[0002] A server, also known as a computer server, is a device that provides computing services. It is a type of computer that provides computing or application services to other client machines (such as PCs, smartphones, ATMs, etc.) on a network. A server's components include a chassis, processor, hard drive, memory, system bus, etc., and its architecture is similar to that of a typical computer. In a network environment, servers are typically categorized based on the type of service they provide, such as file servers, database servers, application servers, and web servers.

[0003] Most current bending equipment relies on telescopic cylinders to drive the bending cutter downwards, lacking effective fixation of the sheet metal near the bending point. This causes the sheet metal to easily shift or twist during bending, resulting in angular deviations and dimensional errors. Similarly, some solutions use fixed limit posts for clamping, but the position of the limit posts is not adjustable, only suitable for workpieces of a single width, and cannot meet the production needs of multiple specifications such as electrical distribution boxes.

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.

[0018] Example

[0019] Please see Figure 1-5 The technical solution provided in this embodiment is as follows: A sheet metal bending device includes: a feeding mechanism 1 and two sets of bending mechanisms 2. The feeding mechanism 1 includes a processing base 101. A mounting plate 102 is fixedly connected to the surface of the processing base 101. A feeding rail 103 is fixedly connected to the surface of the mounting plate 102. A first guide rail 104 and a second guide rail 105 are provided on the surface of the processing base 101 and on both sides of the feeding rail 103. A side pressure plate 106 is slidably connected to the surface of the second guide rail 105. A support plate 108 adapted to the feeding rail 103 is fixedly connected to the surface of the processing base 101. A discharge plate 109 is slidably connected to the surface of the support plate 108. The bending mechanism 2 includes a sliding seat 201 slidably connected to the surface of the first guide rail 104. A support plate 202 is fixedly connected to the surface of the sliding seat 201. A pressing plate 204 adapted to the support plate 202 is slidably connected longitudinally to the surface of the sliding seat 201. A bending plate 206 is rotatably connected to the surface of the sliding seat 201 and located outside the support plate 202. The side pressing plate 106 clamps the plate in both directions synchronously to ensure the center positioning of the plate. The pressing plate 204 is partially pressed down before bending to form a clamping point with the support plate 108, which effectively suppresses warping in the bending area. This makes the device more flexible than the traditional limit post structure, adaptable to plates of any width, and reduces angle error. The double bending mechanism 2 supports parallel operation and can simultaneously bend the two side plates.

[0020] Specifically, the surface of the mounting plate 102 is rotatably connected to two first threaded rods 107, and two side pressure plates 106 are respectively threaded to the surfaces of the two first threaded rods 107.

[0021] In a specific embodiment of this utility model, the second servo motor 115 drives the two first threaded rods 107 to rotate synchronously through the synchronous pulley 113 and the synchronous belt 114, so that the side pressure plate 106 moves in opposite directions along the second guide rail 105, and automatically adjusts the clamping width.

[0022] Specifically, a second threaded rod 110 is rotatably connected to the surface of the pallet 108, and a feed plate 109 is threadedly connected to the surface of the second threaded rod 110. A first servo motor 111 is fixedly connected to the surface of the pallet 108, and the output shaft of the first servo motor 111 is fixedly connected to the second threaded rod 110.

[0023] In a specific embodiment of this utility model, after bending is completed, the first servo motor 111 drives the second threaded rod 110 to rotate, pushing the unloading plate 109 to slide on the pallet 108 and pushing the finished product.

[0024] Specifically, a drive shaft 112 is rotatably connected to the bottom of the mounting plate 102. Synchronous pulleys 113 are fixedly connected to both the surface of the drive shaft 112 and the surface of the first threaded rod 107, and the two synchronous pulleys 113 are connected by a synchronous belt 114.

[0025] In a specific embodiment of this utility model, the second servo motor 115 drives the transmission shaft 112 to rotate, and drives the two first threaded rods 107 to rotate synchronously via the synchronous belt 114, ensuring that the pressure plates 106 on both sides always move symmetrically. The mechanical synchronization mechanism is low in cost and highly reliable, avoiding the problem of slider tilting caused by the asynchronous hydraulic system. The clamping center point is automatically aligned, which is suitable for the stable fixing of irregularly shaped plates.

[0026] Specifically, a second servo motor 115 is fixedly connected to the bottom of the mounting plate 102, and the output shaft of the second servo motor 115 is fixedly connected to the transmission shaft 112.

[0027] In a specific embodiment of this utility model, the output shaft of the second servo motor 115 is directly fixed to the transmission shaft 112, eliminating intermediate transmission errors, improving power transmission efficiency, and resulting in a faster response speed.

[0028] Specifically, a double-threaded screw 116 is rotatably connected to the bottom of the mounting plate 102, and two sliding seats 201 are threadedly connected to the surface of the double-threaded screw 116. A third servo motor 117 is fixedly connected to the bottom of the mounting plate 102, and the output shaft of the third servo motor 117 is fixedly connected to the double-threaded screw 116.

[0029] In a specific embodiment of this utility model, the third servo motor 117 drives the double threaded screw 116 to rotate, causing the two sliding seats 201 to move synchronously in opposite directions along the first guide rail 104, adjusting the bending position, precisely controlling the bending spacing, and adapting to different bending edge width requirements.

[0030] Specifically, a fourth servo motor 203 is fixedly connected to the surface of the sliding seat 201, and the output shaft of the fourth servo motor 203 is fixedly connected to the bending plate 206.

[0031] In a specific embodiment of this utility model, the output shaft of the fourth servo motor 203 is fixedly connected to the bending plate 206, directly providing rotational torque to replace traditional hydraulic or gear transmission.

[0032] Specifically, an electric push rod 205 is fixedly connected to the surface of the sliding seat 201, and the piston rod of the electric push rod 205 is fixedly connected to the pressing plate 204.

[0033] In a specific embodiment of this utility model, the piston rod of the electric push rod 205 extends and retracts, driving the pressing plate 204 to move longitudinally and press down on the bending area of ​​the fixed plate.

[0034] Rubber screw dust covers can be installed on the first threaded rod 107, the second threaded rod 110, and the double-threaded screw 116 for dust prevention, depending on the situation. Regular or irregular lubrication and maintenance are required. The screw dust covers are installed on the mounting plate 102 and the side pressure plate 106 respectively, covering the exposed portion of the first threaded rod 107. The screw dust covers are installed on the connection end between the feed plate 109 and the second threaded rod 110, and on the connection end between the support plate 108 and the second threaded rod 110, covering the second threaded rod 110. The screw dust cover is installed between the connection point of the mounting plate 102 and the double-threaded screw 116 and the sliding seat 201 to cover the double-threaded screw 116. This screw dust cover is a common method in the prior art and will not be described in detail here.

[0035] Working principle: The sheet material is conveyed to the processing area on the pallet 108 by the feeding rail 103. The second servo motor 115 drives the first threaded rod 107 to rotate through the transmission shaft 112 and the synchronous belt 114, so that the pressure plates 106 on both sides slide along the second guide rail 105 and clamp the sheet material from the left and right sides to ensure that it is in the preset position. Then, the bending mechanism 2 starts the third servo motor 117 to drive the double threaded screw 116, which drives the two sliding seats 201 to move along the first guide rail 104 to the target bending point. The electric push rod 205 pushes the pressing plate 204 down. The fourth servo motor 203 directly drives the bending plate 206 to rotate, so that the sheet material undergoes plastic bending between the support plate 202 and the bending plate 206. After the bending is completed, the pressing plate 204 is retracted. The first servo motor 111 drives the second threaded rod 110 to push the unloading plate 109 to unload the finished product.

[0036] 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.
