Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a processing device for sheet metal bevels. Background Technology

[0002] In sheet metal products, external force is usually applied to cause plastic deformation of the sheet metal, forming a bend at a specific angle and shape, thereby turning a flat metal sheet into various parts or components with three-dimensional shapes. After sheet metal parts have been processed by cutting, punching, etc., the edges are often quite sharp, so a flanging process is needed to fold these sharp edges to form rounded or smooth edges.

[0003] However, the existing sheet metal workpieces have discontinuous processing during the bevel process, resulting in low processing efficiency and an uneven, non-smooth structure on the bevel. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a sheet metal bevel processing device, which can form a sheet metal bevel through the bevel interval between the first conical wheel segment of the first pressure roller and the second conical wheel segment of the second pressure roller, and simultaneously clamp and guide the sheet metal side with the first guide wheel segment and the second guide wheel segment, and realize continuous bevel forming action in conjunction with the rotation of the workpiece turntable.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0026] See Figure 1 , Figure 2 as well as Figure 3This utility model discloses a processing device for sheet metal bevels, including a processing table 10 and a bevel assembly. A workpiece turntable 11 and a turntable drive are provided on the processing table 10. The workpiece turntable 11 is rotatably mounted on the processing table 10, and the turntable drive drives the workpiece turntable 11 to rotate.

[0027] The bevel assembly is mounted on the processing table 10. The bevel assembly includes a first pressure roller 21, a first driving member 23, a second pressure roller 22, and a second driving member 24. Specifically, the first pressure roller 21 includes a first guide roller segment 211 and a first conical roller segment 212, which are connected vertically. The second pressure roller 22 includes a second guide roller segment 221 and a second conical roller segment 222, which are connected vertically to the second guide roller segment 221. The second pressure roller 22 can be positioned above the first pressure roller 21, and the second conical roller segment 222 can be spaced apart from the first conical roller segment 212 to form a bevel.

[0028] The first driving member 23 can drive the first pressure roller 21 to move closer to or away from the workpiece turntable 11 along the processing direction; the second driving member 24 drives the second pressure roller 22 to move closer to or away from the workpiece turntable 11 along the processing direction.

[0029] Based on the above structure, when using the sheet metal bevel processing device of this utility model, the first driving member 23 can drive the first pressure roller 21 to approach the workpiece turntable 11 and clamp the sheet metal workpiece onto the workpiece turntable 11. After the workpiece is clamped onto the workpiece turntable 11, the first pressure roller 21 can abut against the inner wall of the side of the sheet metal workpiece. The second driving member 24 drives the second pressure roller 22 to approach the workpiece turntable 11 and abut against the outer wall of the side of the sheet metal workpiece. In this way, the side of the workpiece is located between the first pressure roller 21 and the second pressure roller 22. The first driving member 23 drives the first pressure roller 21 to move away from the workpiece turntable 11 and outward. The first conical wheel segment 212 can push outward from the bottom end of the side of the sheet metal workpiece. At the same time, the second conical wheel segment 222 is limited on the outer side of the bottom end of the side of the sheet metal workpiece. The bevel interval formed by the cooperation makes the bottom end of the side of the sheet metal workpiece form a bevel structure.

[0030] In addition, the turntable drive can drive the workpiece turntable 11 to rotate, and drive the workpiece on the workpiece turntable 11 to rotate. In this way, the inner side of the top edge of the sheet metal workpiece can rotate continuously under the guidance of the first guide wheel section 211, and the outer side of the bottom edge of the sheet metal workpiece can rotate continuously under the guidance of the second guide wheel section 221. This continuous rotation and continuous bevel forming action reduces unevenness that occurs during the forming process.

[0031] Furthermore, the bevel assembly includes a mounting bracket 25, at the bottom of which a first slide block 251 and a first slide rail are provided, with the first slide block 251 and the first slide rail being slidably engaged. The first pressure roller 21 is rotatably mounted on the first slide block 251 via a first rotating shaft. The first driving member 23 can drive the first slide block 251 to slide. When the first driving member 23 drives the first pressure roller 21 to move, the first driving member 23 can drive the first slide block 251 to move along the first slide rail, thus driving the first pressure roller 21 on the first slide block 251 to move, and the movement of the first pressure roller 21 is stable.

[0032] Similarly, a second slide block 252 and a second slide rail are provided at the top of the mounting bracket 25; the second slide block 252 and the second slide rail are slidably engaged; the second pressure roller 22 is rotatably mounted on the second slide block 252 via a second rotating shaft; the second driving member 24 is used to drive the second slide block 252 to slide. When the first driving member 23 drives the second pressure roller 22 to move, the second driving member 24 can drive the second slide block 252 to move along the second slide rail, thus driving the second pressure roller 22 on the second slide block 252 to move, and the movement of the second pressure roller 22 is stable.

[0033] Furthermore, the processing table 10 is provided with a third slide rail 12, and the bottom end of the mounting frame 25 is provided with a slide groove. The slide groove slides in cooperation with the third slide rail 12. In this way, the mounting frame 25 can slide in cooperation with the third slide rail 12 of the processing table 10 through its own slide groove structure. Thus, the position of the mounting frame 25 relative to the workpiece turntable 11 can also be adjusted, which is suitable for different outer diameter dimensions of sheet metal workpieces.

[0034] When the outer diameter of the sheet metal workpiece is large, the mounting bracket 25 moves along the third slide rail 12 in a direction away from the workpiece turntable 11. The first pressure roller 21 and the second pressure roller 22 on the mounting bracket 25 can then move away from the sheet metal workpiece on the workpiece turntable 11, which is suitable for pressing the beveled edges of sheet metal workpieces with large outer diameters. Conversely, when the outer diameter of the sheet metal workpiece is small, the mounting bracket 25 moves along the third slide rail 12 in a direction away from the workpiece turntable 11. The first pressure roller 21 and the second pressure roller 22 on the mounting bracket 25 can then move away from the sheet metal workpiece on the workpiece turntable 11, which is suitable for pressing the beveled edges of sheet metal workpieces with small outer diameters.

[0035] The sliding of the first pressure roller 21 and the second pressure roller 22 on the mounting bracket 25 adjusts the pressure edge position.

[0036] It should be noted that the extension directions of the first slide rail, the second slide rail, and the third slide rail 12 are all processing directions. In this embodiment, the processing direction is the radial direction of the processing table 10.

[0037] Furthermore, the processing table 10 is equipped with a third driving component 26, which includes an adjusting screw and a nut seat at the bottom of the mounting bracket 25. The adjusting screw is rotatably connected to the nut seat and is used to drive the mounting bracket 25 to move during rotation. In this way, by rotating the adjusting screw, the adjusting screw rotates relative to the nut seat. During the rotation, the mounting bracket 25 is guided to slide in the processing direction through the sliding engagement of the slide groove and the third slide rail 12. The position of the mounting bracket 25 is adjusted by matching the threads of the adjusting screw and the nut seat, resulting in high adjustment accuracy.

[0038] Furthermore, the processing table 10 is provided with multiple positioning blocks 13, which surround the outer periphery of the workpiece turntable 11 and are spaced apart in the circumferential direction of the workpiece turntable 11. The end faces of the multiple positioning blocks 13 together form a positioning surface that supports the bottom end of the workpiece. In this way, when processing the bevel of the sheet metal workpiece, the sheet metal workpiece is fitted onto the outside of the workpiece turntable 11, and the bottom end of the sheet metal workpiece is supported by the multiple positioning blocks 13. In this way, the bottom end of the sheet metal workpiece is supported by the positioning surface, preventing up-and-down wobbling during the bevel pressing and forming process.

[0039] Further, see Figure 3 The positioning block 13 is provided with a number of positioning steps 131 arranged at intervals from top to bottom, and the positioning steps 131 are spaced apart and staggered in the height direction of the positioning block 13. In this way, there are positioning steps 131 at different height positions of the positioning block 13. After the sheet metal workpiece is placed on the workpiece turntable 11, the bottom end of the sheet metal workpiece can be supported by different positioning steps 131 according to the height of the sheet metal workpiece itself, which has a wider range of applications.

[0040] Furthermore, the processing table 10 is also provided with a fourth driving member 14, which is used to drive the positioning block 13 to move up and down along its own height direction. In this way, the positioning block 13 can be adjusted on the processing table 10 by driving the positioning block 13 to move up and down through the fourth driving member 14, and the supporting position of the positioning block 13 can be adjusted according to the height of the workpiece.

[0041] It should be noted that the first driving component 23 and the second driving component 24 can both be implemented using existing cylinders or hydraulic cylinders, where the piston rod of the cylinder or hydraulic cylinder extends or retracts to drive the corresponding first pressure roller 21 and second pressure roller 22. The aforementioned fourth driving component 14 can also be implemented using existing cylinders or hydraulic cylinders. For example, the fourth driving component 14 includes two cylinders, with the top ends of the piston rods of the two cylinders connected to a mounting plate, and the positioning block 13 can be mounted on the mounting plate.

[0042] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
