[0050] As described in the background section of this application, valves such as regulating valves and ventilation valves include a valve body and blades, such as Figure 1 As shown, the valve body 100 is rectangular, with protruding edges 110 at both ends forming flange mounting portions. The valve body 100 is formed by folding the sides of a thin steel plate 90° in a forming machine to create the protruding edges 110, punching and cutting process holes and slits in the thin steel plate, and then cutting the steel plate to the required length in the forming machine to obtain a pre-processed elongated valve body 100. Finally, the elongated valve body is bent three times, and both ends are fixed to obtain the final product. Figure 1 The rectangular frame valve body 100 shown.

[0051] The inventors of this application have discovered that bending of long strip valve bodies currently relies on manual labor, which is time-consuming and inefficient.

[0052] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

[0053] Figure 2 This is a schematic diagram of a bending device for a valve body in an embodiment of this utility model. Figure 3 This is a schematic diagram of the first pressing mechanism in an embodiment of the present invention. Figure 4 This is a schematic diagram of the support base and pressure block in an embodiment of the present utility model. Figure 5 As described in the embodiments of this utility model Figure 2 A magnified view of a portion of the image.

[0054] like Figures 2 to 5 As shown, the bending device for the valve body in this embodiment includes: a frame 1, a conveying mechanism, a first driving mechanism 3, a first support 4, a first pressing mechanism, a bending mechanism, and a controller.

[0055] The frame 1 is located adjacent to the valve body 100 forming equipment, at the rear end of the valve body forming equipment. The conveying mechanism is located on the frame 1. The steel plate is bent and formed by the protruding edge 110, punched by the process hole and cut by the cutting on the forming equipment, and cut into strip-shaped valve bodies according to the required length. The cut strip-shaped valve bodies are conveyed to the conveyor belt 21 of the conveying mechanism, and the conveyor belt 21 continues to convey the strip-shaped valve bodies 100 to the rear end (end) of the frame 1.

[0056] The frame 1 is provided with guide rails 11, which are arranged on both sides of the conveyor belt 21 along the conveying direction of the conveying mechanism. The first support 4 is slidably mounted on the guide rail 11 of the frame 1 by a slider. The first drive mechanism 3 is mounted on the first support 4 and is used to move the first support 4 along the guide rail 11 of the frame 1.

[0057] The first clamping mechanism is mounted on the first bracket 4. The first clamping mechanism is used to clamp and fix the end of the valve body 100 so that the valve body 100 is fixed on the frame 1.

[0058] The bending mechanism is mounted on the frame 1 and located at the end of the frame 1.

[0059] The bending mechanism includes: a fixed base 61, a lower module 62, a second pressing mechanism 63, and a second driving mechanism 64.

[0060] Both the fixed base 61 and the lower module 62 are rectangular.

[0061] The fixed seat 61 is fixedly mounted on the frame 1 and is adjacent to the end of the conveyor belt 21. The valve body 100 conveyed by the conveyor belt 21 is conveyed to the fixed seat 61, and the fixed seat 61 provides support for the valve body 100.

[0062] The second clamping mechanism 63 is mounted on the frame 1 and located above the fixed base 61. The second clamping mechanism 63 is used to clamp and fix the valve body 100 onto the fixed base 61.

[0063] The lower module 62 is rotatably mounted on the frame 1, arranged side by side with the fixed base 61, and located outside the fixed base 61. When the lower module 62 is horizontal, the top surface of the lower module 62 is flush with the top surface of the fixed base 61, providing support for the valve body 100.

[0064] The lower module 62 is connected to the second drive mechanism 64. The second drive mechanism 64 is used to drive the lower module 62 to rotate, so that the horizontal lower module 62 rotates to a vertical position of 90°. When the lower module 62 rotates, it pushes the valve body 100, so that the head end of the valve body 100 is folded 90° relative to the valve body, thereby realizing the bending and folding of the valve body 100.

[0065] The conveying mechanism, the first driving mechanism 3, the first pressing mechanism 63, the second pressing mechanism 64 and the second driving mechanism 64 are electrically connected to the controller, and the controller controls each mechanism to perform corresponding preset actions according to the preset program.

[0066] It is not difficult to see from the above that the bending device for valve bodies in this embodiment includes a frame, a conveying mechanism, a first driving mechanism, a first support, a first pressing mechanism, a bending mechanism, and a controller. The conveying mechanism is mounted on the frame, the first support is mounted on the guide rail of the frame, the first driving mechanism is mounted on the first support, the first pressing mechanism is mounted on the first support, and the bending mechanism is mounted on the frame. The device includes a fixed seat, a lower module, a second pressing mechanism, and a second driving mechanism. The second pressing mechanism presses the valve body onto the fixed seat, and the lower module is mounted on the frame and connected to the second driving mechanism. The bending equipment for valve bodies in this embodiment is controlled by a controller. The elongated valve body is conveyed to the front end of the frame by a conveyor belt. The first drive mechanism drives the first support to move to the end of the valve body. The first clamping mechanism clamps and fixes the valve body. Then, the first drive mechanism pushes the valve body forward to extend a preset length. The second clamping mechanism presses the valve body onto the fixed seat. The second drive mechanism pushes the lower module to rotate. The lower module pushes the front end of the valve body to fold 90°. After three folds and bends, the elongated valve body is deformed into a rectangular frame-shaped valve body. The valve body is formed quickly, which improves production efficiency. By fixing the two ends of the rectangular frame, the formed rectangular frame-shaped valve body can be obtained.

[0067] Optionally, in this embodiment, the bending device for the valve body has a straight rack 12 on the top surface of the frame 1.

[0068] The first drive mechanism 3 includes a servo motor 31 and a transmission gear 32.

[0069] The servo motor 31 is mounted on the first bracket 4. The transmission gear 32 is connected to the output shaft of the servo motor 31, and the transmission gear 32 is meshed with the linear rack 12. The servo motor 31 drives the transmission gear 32 to rotate. When the transmission gear 32 rotates, it drives the first bracket 4 to slide along the guide rail 11 of the frame 1, so that the frame 1 moves closer to the end of the long strip valve body.

[0070] Optionally, in this embodiment, the bending device for the valve body includes a first pressing mechanism comprising: a movable bracket 51, a first hydraulic cylinder 52, a second hydraulic cylinder 53, a support base 54, and a pressing block 55.

[0071] The first hydraulic cylinder 52 is fixedly mounted on the first bracket 4, and the movable bracket 51 is slidably mounted on the slide rail of the first bracket 4. The movable bracket 51 is connected to the telescopic rod of the first hydraulic cylinder 52, and the extension and retraction of the telescopic rod of the first hydraulic cylinder 52 causes the movable bracket 51 to slide up and down along the slide rail of the first bracket 4.

[0072] The support base 54 and the second hydraulic cylinder 53 are fixedly mounted on the movable bracket 51. The pressure block 55 is rotatably mounted on the movable bracket 51 via a rotating shaft. One end of the pressure block 55 is connected to the telescopic rod of the second hydraulic cylinder 53. The extension and retraction of the telescopic rod of the second hydraulic cylinder 53 causes the pressure block 55 to rotate around the rotating shaft, so that the other end of the pressure block 55 approaches and / or moves away from the support base 54. When the pressure block 55 approaches the support base 54, it is used to clamp and fix the end of the valve body 100 on the support base 54, so that the long strip valve body 100 is fixed on the frame 1.

[0073] Furthermore, in this embodiment, the bending device for the valve body has a limiting step 541 at the front end (right end) of the support base 54.

[0074] The pressure block 55 is L-shaped at a right angle. The front end of the pressure block 55 has a protrusion 551, which is used to press the valve body against the step shoulder of the limiting step 541 of the support seat 54.

[0075] Optionally, in this embodiment, the bending device for the valve body, the second pressing mechanism 63 includes: a third hydraulic cylinder 631, a second bracket 632, and an upper module 633.

[0076] The third hydraulic cylinder 631 is mounted on the frame 1, and the second bracket 632 is connected to the telescopic rod of the third hydraulic cylinder 631.

[0077] The upper module 633 is rectangular and is mounted on the second bracket 632. The upper module 633 is located above the fixed seat 61. The extension and retraction of the telescopic rod of the third hydraulic cylinder 631 drives the second bracket 632 and the upper module 633 to rise and fall. When the upper module 633 descends, it presses and fixes the valve body 100 against the fixed seat 61.

[0078] Optionally, in this embodiment, the bending device for the valve body includes a second drive mechanism 64 comprising a fourth hydraulic cylinder 641 and a lower die frame 642.

[0079] The two sides of the lower mold frame 642 are rotatably mounted on the frame 1 via rotating shafts, and the lower module 62 is mounted on the lower mold frame 642.

[0080] The bottom end of the fourth hydraulic cylinder 641 is hinged to the frame 1. The telescopic rod of the fourth hydraulic cylinder 641 is hinged to the lower mold frame 642. The extension and retraction of the telescopic rod of the fourth hydraulic cylinder 641 drives the lower mold frame 642 and the lower module 62 to rotate.

[0081] In this embodiment, the elongated valve body is conveyed to the fixed seat, and the front end of the valve body extends out of the fixed seat. The upper module presses down on the valve body to fix it on the fixed seat. Then, the telescopic rod of the fourth hydraulic cylinder pushes the lower module to rotate 90°. The lower module pushes the front end of the valve body to fold 90° relative to the fixed part of the valve body, and the valve body abuts against the side wall of the upper module, completing one folding and bending of the elongated valve body. After three folding and bending, the elongated valve body is formed into a rectangular frame-shaped valve body.

[0082] Furthermore, in this embodiment, the second drive mechanism 64 of the bending device for the valve body also includes a roller 643.

[0083] The roller 643 is rotatably mounted on the lower mold frame 642 and located on both sides of the lower module 62. The roller 643 abuts against the protruding edge 110 of the valve body 100, clamping the protruding edge 110 between the roller 643 and the lower module 62, making the valve body more stable on the lower module.

[0084] Optionally, in this embodiment, the bending device for the valve body has a side guide strip 13 on the frame 1, which is disposed on both sides of the transmission belt 21. When the elongated valve body 100 is conveyed, the side guide strip 13 abuts against the convex edge 110 of the valve body 100 to prevent the valve body 100 from shifting during the conveying process.

[0085] Optionally, in this embodiment, the bending device for the valve body has a limiting block 14 at the end of the frame 1, and a sensor 15 is provided on the limiting block 14. The sensor 15 is electrically connected to the controller.

[0086] Servo motor 31 drives the first bracket 4 to move towards the end of the frame 1. When sensor 15 senses the first bracket 4, it sends a signal to the controller. The controller controls the first bracket 4 to stop moving. At the same time, the limit block 14 also blocks the first bracket 4 to prevent the first bracket 4 from sliding out of the frame 1.

[0087] Furthermore, in this embodiment, the bending device for the valve body has an emergency stop button 16 at the end of the frame 1.

[0088] Control switch 16 is electrically connected to the controller to shut down the equipment in an emergency.

[0089] The bending device for valve bodies of this utility model has the following working process:

[0090] The long strip valve body, which is pre-formed and cut on the forming equipment, is conveyed to the conveyor belt of the bending equipment. The conveyor belt continues to transport the valve body. At this time, the lower module flips and becomes vertical, forming a limiting baffle at the bending station. The head end of the valve body stops moving after it abuts against the lower module.

[0091] Then, the servo motor drives the first bracket to move towards the valve body (right side) through the transmission gear. At the same time, the first hydraulic cylinder drives the movable bracket to descend. When the limit step of the support seat abuts against the end of the valve body, the second hydraulic cylinder drives the pressure block to rotate. The protrusion of the pressure block presses and fixes the end of the valve body against the support seat.

[0092] Then the fourth hydraulic cylinder drives the lower module to rotate 90° to a horizontal position, the servo motor drives the first bracket to continue moving to the right, pushing the valve body to the right, so that the preset length of the front end of the valve body extends out of the fixed seat to the lower module, and the third hydraulic cylinder drives the upper module to descend, pressing and fixing the valve body against the fixed seat.

[0093] Then, the fourth hydraulic cylinder pushes the lower module to rotate 90° to a vertical position. The lower module pushes the front end of the valve body, causing the valve body extending from the fixed seat to rotate and bend 90°, completing one bend of the long strip valve body.

[0094] Then, the lower module flips again to a horizontal position, the upper module rises, and the servo motor drives the frame to continue moving to the right, so that the front end of the valve body extends out of the fixed seat by the preset length again. The upper module presses the valve body, and the lower module flips again by 90° to a vertical position, so that the valve body flips and bends by 90° again.

[0095] The long, strip-shaped valve body is bent three times and then deformed into a rectangular frame-shaped valve body.

[0096] Finally, after removing the rectangular frame valve body, fix both ends of the rectangular frame to obtain the formed rectangular frame valve body.

[0097] The bending equipment of this utility model is driven by a servo motor and equipped with multiple sensors, which can achieve high-precision speed control, realize accurate positioning of the valve body during movement, and ensure the bending dimensional accuracy of the valve body.
