Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, specifically a synchronous bending device for a high-efficiency CNC bending machine. Background Technology

[0002] A CNC bending machine is a sheet metal processing device that uses matching molds to bend and shape metal sheets at room temperature, thereby manufacturing workpieces with various geometric cross-sectional shapes. This equipment is specifically designed for the forming and processing of cold-rolled sheet metal and is widely used in various industries such as automobile manufacturing, aerospace, light industrial machinery, shipbuilding, container production, elevator equipment, and rail transportation.

[0003] However, existing CNC bending machines typically rely on manual positioning, calibration, and feeding operations by operators during sheet metal bending. This not only poses certain safety risks but is also prone to deviations in bending position due to human error, affecting processing accuracy. Furthermore, most existing equipment only supports single-piece sequential processing, resulting in low production efficiency.

[0004] Therefore, it is necessary to provide a bending machine that can avoid manual calibration and feeding, and has a higher level of safety and automation, in order to improve processing accuracy and work efficiency. Utility Model Content

[0005] Based on this, this solution provides a synchronous bending device for a high-efficiency CNC bending machine. Through the synchronous structure, multiple parts can be bent simultaneously, and manual feeding is avoided, reducing the danger of operation and improving the bending accuracy of the sheet metal.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A synchronous bending device for a high-efficiency CNC bending machine includes a bending machine body, a synchronous structure on the side of the bending machine body, a bending die, a support frame on the side of the bending machine body, a limit groove on the support frame, a mounting plate slidably connected to the support frame through the limit groove, a push rod slidably connected to the inner side of the mounting plate, and a movable structure on the bottom side of the support frame.

[0008] Optionally, in one embodiment of the present invention, the end of the mounting plate is a square structure, and the end of the mounting plate is slidably connected to the inner side of the limiting groove through the square structure.

[0009] Optionally, in one embodiment of the present invention, an adjusting screw is threadedly connected to the middle of the mounting plate, and the end of the adjusting screw is rotatably connected to the push rod.

[0010] Optionally, in one embodiment of the present invention, the middle part of the mounting plate is provided with a groove structure, and the inner side of the mounting plate is horizontally aligned with the surface of the bending mold.

[0011] Optionally, in one embodiment of the present invention, a positioning rod is slidably connected to each side of the support frame, and a spring is fixedly connected between the positioning rod and the support frame.

[0012] Optionally, in one embodiment of the present invention, a positioning groove is provided on each side of the mounting plate, and the end of the positioning rod has a hemispherical structure, with the spherical end of the positioning rod abutting against the mounting plate through the positioning groove.

[0013] Optionally, in one embodiment of the present invention, the movable structure includes a toothed groove, the bottom side of the mounting plate is provided with a toothed groove, and a second gear is rotatably connected to each side of the support frame, the second gear meshing with the mounting plate through the toothed groove.

[0014] Optionally, in one embodiment of the present invention, a transmission rod is rotatably connected to the middle of the support frame, and a first gear is fixedly connected to each end of the transmission rod, and the first gear meshes with a second gear arranged on the same side.

[0015] Optionally, in one embodiment of the present invention, a drive rod is rotatably connected to the side of the support frame, a bevel gear is fixedly connected to the drive rod, and the end of the drive rod meshes with the corresponding bevel gear.

[0016] Compared with the prior art, the synchronous bending device of the high-efficiency CNC bending machine provided by this utility model has the following characteristics:

[0017] A mounting plate capable of simultaneously supporting multiple sheet metal plates is provided, and a movable structure allows the entire assembly to be transported to the bending station, ensuring that all sheet metal plates are initially positioned identically relative to the bending die. This enables the bending machine to complete the bending of all sheet metal plates in one operation, eliminating the problem of inconsistent bending angles and dimensions caused by batch operations and improving the processing accuracy of the product.

[0018] The structure inside the limiting groove prevents the mounting plate from rotating after it leaves the end of the limiting groove, thus ensuring the horizontal movement of the material plate and avoiding angular deviations caused by the deflection of the mounting plate during the conveying process, thereby ensuring the straightness of the bending line.

[0019] It is equipped with an adjusting screw, which can precisely control the displacement of the push rod, thereby precisely controlling the position of the bending line on the material plate.

[0020] Workers can place multiple sheets of material to be bent into the groove structure of the mounting plate at one time, and then complete the positioning and feeding of all the sheets in one go through mechanical transmission.

[0021] The mounting plate can be rotated to a vertical position and temporarily positioned by a positioning rod and spring mechanism, allowing the operator to easily and accurately place the plate into the trough. Attached Figure Description

[0034] Example 1

[0035] Because existing bending machines require manual calibration and feeding, which poses certain operational risks, a safer bending device was designed, and the specific solution is as follows:

[0036] like Figure 1-8 As shown, a synchronous bending device for a high-efficiency CNC bending machine includes a bending machine body 1. A synchronous structure 2 is provided on the side of the bending machine body 1. The synchronous structure 2 includes a bending die 201. The bending die 201 is installed on the bending machine body 1. A support frame 202 is installed on the side of the bending machine body 1. A limit groove 209 is provided on the support frame 202. A mounting plate 203 is slidably connected to the support frame 202 through the limit groove 209. A push rod 205 is slidably connected to the inner side of the mounting plate 203. A movable structure 3 is provided on the bottom side of the support frame 202.

[0037] The end of the mounting plate 203 has a square structure, which is slidably connected to the inner side of the limiting groove 209. The structure inside the limiting groove 209 prevents the mounting plate 203 from rotating after it disengages from the end of the limiting groove 209, thus ensuring the horizontal movement of the material plate. An adjusting screw 204 is threadedly connected to the middle of the mounting plate 203. The end of the adjusting screw 204 is rotatably connected to the pushing rod 205. Rotating the adjusting screw 204 makes the pushing of the material plate smoother and facilitates control of the bending position of the material plate. The middle of the mounting plate 203 has a groove-shaped structure. The inner side of 203 is horizontally aligned with the surface of the bending die 201. A positioning rod 207 is slidably connected to each side of the support frame 202. A spring 208 is fixedly connected between the positioning rod 207 and the support frame 202. A positioning groove 206 is opened on each side of the mounting plate 203. The end of the positioning rod 207 is a hemispherical structure. The spherical end of the positioning rod 207 abuts against the mounting plate 203 through the positioning groove 206. With the setting of the positioning rod 207, the mounting plate 203 can be positioned when the mounting plate 203 is rotated to a vertical state, which makes it convenient to place the material plate to be bent into the groove structure in the middle of the mounting plate 203.

[0038] The movable structure 3 includes a toothed groove 306. A toothed groove 306 is formed on the bottom side of the mounting plate 203. A second gear 305 is rotatably connected to each side of the support frame 202. The second gear 305 meshes with the mounting plate 203 through the toothed groove 306. A transmission rod 302 is rotatably connected to the middle of the support frame 202. A first gear 304 is fixedly connected to each end of the transmission rod 302. The first gear 304 meshes with the second gear 305 on the same side. A drive rod 301 is rotatably connected to the side of the support frame 202. A bevel gear 303 is fixedly connected to the transmission rod 302. The end of the drive rod 301 engages with the corresponding bevel gear 303. To facilitate the movement of the drive plate 203, after the material plate is placed, the user can rotate the drive rod 301 located on the side of the support frame 202. Through the transmission effect of the bevel gear 303 meshing at the end of the drive rod 301, the transmission rod 302 can be driven to rotate. Then, through the transmission action of the first gear 304 and the second gear 305, since the material plate 203 cannot rotate when sliding through the limiting groove 209, the second gear 305 can drive the material plate 203 to move towards the bending mold 201 through the tooth groove 306 on the bottom side of the material plate 203 until the bending operation is performed, ensuring the synchronous bending of all placed material plates.

[0039] Equipment Description:

[0040] First, a mounting plate 203 is set on one side of the CNC bending machine mold to support the material plate to be bent. The mounting plate 203 is slidably connected to the support frame 202. When multiple material plates need to be bent simultaneously, the material plates are first placed inside the mounting plate 203, and then the mounting plate 203 is rotated. At this time, the material plates inside the mounting plate 203 will slide to the side and abut against the push rod 205, thus completing the correction of the material plate position.

[0041] By setting the positioning rod 207, the mounting plate 203 can be positioned when it is rotated to a vertical position, making it convenient to place the material plate to be bent into the groove structure in the middle of the mounting plate 203. Then, the mounting plate 203 is rotated back to a horizontal position. At this time, the sliding push rod 205 pushes the material plate outward and away from the mounting plate 203. The mounting plate 203 can then be moved so that the bending area of ​​the material plate on the mounting plate 203 is moved onto the bending die 201. Once the mounting plate 203 is away from the end of the limiting groove 209, it cannot rotate, thus ensuring the horizontal movement of the material plate. By rotating the adjusting screw 204, the pushing of the material plate is made smoother and the bending position of the material plate is easier to control. Finally, the bending machine is started, and multiple parts are bent in the same area at the same time, avoiding manual addition of materials and ensuring the accuracy of the bending position.

[0042] To facilitate the movement of the mounting plate 203, after the material plate is placed, the user can rotate the drive rod 301, which in turn drives the transmission rod 302 to rotate. Through the transmission of the first gear 304 and the second gear 305, since the mounting plate 203 cannot rotate when sliding through the limiting groove 209, the second gear 305 can drive the mounting plate 203 to move towards the bending mold 201 through the tooth groove 306 until the bending operation is performed, ensuring that all the placed material plates are bent synchronously.

[0043] The synchronous bending device in this solution includes a mounting plate 203 that can simultaneously support multiple material plates. A movable structure 3 allows the entire plate to be moved to the bending station, ensuring that all material plates are initially positioned identically relative to the bending die. The bending machine can complete the bending of all material plates in one operation, eliminating the problems of inconsistent bending angles and dimensions caused by batch operations, resulting in high product processing accuracy.

[0044] The structure inside the limiting groove 209 prevents the mounting plate 203 from rotating after it leaves the end of the limiting groove 209, thus ensuring the horizontal movement of the material plate and avoiding angular deviation caused by the deflection of the mounting plate during the conveying process, thereby ensuring the straightness of the bending line.

[0045] Adjusting the screw 204 allows for precise control of the displacement of the push rod 205, thereby precisely controlling the position of the bending line on the material plate.

[0046] Workers can place multiple plates to be bent into the groove structure of the mounting plate 203 at once, and then complete the positioning and feeding of all plates in one go through mechanical transmission.

[0047] The mounting plate 203 can be rotated to a vertical position and temporarily positioned by the positioning rod 207 and spring 208 mechanism, allowing the operator to easily and accurately place the plate into the slot.

[0048] Example 2

[0049] In this embodiment, the structure of the synchronous bending device is basically the same as that of Embodiment 1. The difference is that the manually rotated drive rod 301 is replaced by a servo motor drive. The servo motor is electrically connected to the control system of the bending machine. The control system of the bending machine can control the mounting plate to realize automation from feeding, positioning, bending to unloading, and further improve the efficiency of the equipment.
