Detailed Implementation

[0024] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

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.

[0026] 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.

[0027] See Figures 1-4 This utility model discloses an automatic edge-pressing device for sheet metal workpieces, including a processing table 10 and an edge-pressing assembly 20. The processing table 10 is provided with a workpiece turntable 11 and a turntable drive component. The workpiece turntable 11 is loaded with workpieces. The workpiece turntable 11 is rotatably mounted on the processing table 10, and the turntable drive component can drive the workpiece turntable 11 to rotate.

[0028] The specific edge-pressing assembly 20 includes a first edge-pressing member, a second edge-pressing member, a first edge-pressing drive member 23, and a second edge-pressing drive member 24. The first edge-pressing member can move closer to or away from the workpiece turntable 11 along the processing direction. After moving away from the workpiece turntable 11, the first edge-pressing member can bend the workpiece to form a flange. The second edge-pressing member can move closer to or away from the workpiece turntable 11 along the processing direction. After moving closer to the workpiece turntable 11, the second edge-pressing member is pressed onto the flange.

[0029] Based on the above structure, the automatic edge pressing device for sheet metal workpieces of this utility model is used. When the sheet metal workpiece is pressed, the first edge pressing member approaches the workpiece turntable 11 under the drive of the first edge pressing drive member 23, and sets the sheet metal workpiece on the outer periphery of the workpiece turntable 11. The sheet metal workpiece is distributed in a ring on the workpiece turntable 11. The first edge pressing member can abut against the inner side of the bottom end of the sheet metal workpiece. Then, the first edge pressing member can move away from the workpiece turntable 11 under the drive of the first edge pressing drive member 23, so that the bottom end of the sheet metal workpiece is bent outward to form a flange. At this time, the first edge pressing member supports the bottom end of the flange of the sheet metal workpiece, while the second edge pressing member can approach the flange and press on the flange under the drive of the second edge pressing drive member 24.

[0030] Subsequently, the turntable drive can drive the workpiece turntable 11 to rotate, and the sheet metal workpiece clamped on the workpiece turntable 11 can rotate synchronously. During this process, the bottom side edge of the sheet metal workpiece can be bent synchronously under the action of the first and second pressing parts and the flanging is pressed and flattened to form a continuous flanging structure. The flanging forming efficiency is high and the quality is good.

[0031] It should be noted that the above machining direction is the radial direction of the workpiece turntable 11.

[0032] Furthermore, the pressing assembly 20 in this embodiment also includes a mounting bracket 25. The first pressing component includes a first pressing seat 26 and a first pressing wheel 21. The first pressing seat 26 is slidably mounted on the mounting bracket 25 and slides along the processing direction. The first pressing wheel 21 is rotatably mounted on the first pressing seat 26. The first pressing drive component 23 is used to drive the first pressing seat 26 to slide.

[0033] Based on this structure, when the first pressing edge is moved, the first pressing edge drive 23 can drive the first pressing edge seat 26 to move radially along the workpiece turntable 11. This can drive the first pressing edge wheel 21 on the first pressing edge seat 26 to move. After the first pressing edge wheel 21 presses the sheet metal workpiece from the inside to bend and turn it over, the workpiece turntable 11 rotates. The turning edge of the sheet metal workpiece rolls and cooperates with the wheel surface of the first pressing edge wheel 21, making it less likely to jam and making the turning edge forming process smoother.

[0034] Furthermore, the second pressing element includes a second pressing seat 27 and a second pressing wheel 22. The second pressing seat 27 is slidably mounted on the mounting bracket 25 and can slide along the processing direction. The second pressing wheel 22 is rotatably mounted on the second pressing seat 27. The second pressing drive 24 can drive the second pressing seat 27 to slide. The rotation axis of the second pressing wheel 22 is perpendicular to the rotation axis of the first pressing wheel 21.

[0035] During the pressing action, the first pressing wheel 21 can push the bottom side edge of the sheet metal workpiece outward from the vertical direction for bending, and the flange can be supported by the wheel surface of the first pressing wheel 21. Since the rotation axis of the second pressing wheel 22 is perpendicular to the rotation axis of the first pressing wheel 21, the wheel surface of the first pressing wheel 21 can support the flange in the vertical direction, and the wheel surface of the second pressing wheel 22 presses the flange in the horizontal direction to form and shape the flange.

[0036] Furthermore, the outer circumferential surface of the top of the first pressing wheel 21 has a first pressing wheel surface 211, and the first pressing wheel surface 211 is an arc surface. The outer diameter of the first pressing wheel surface 211 gradually increases from top to bottom. That is, when the first pressing wheel 21 presses the bottom side of the sheet metal workpiece outward to form a flange, the arc surface of the first pressing wheel surface 211 contacts the sheet metal workpiece, and the surface of the flange formed in this way is an arc surface. Compared with bending with a straight surface, it is less likely to break, and after the flange is formed, it connects with the sheet metal workpiece with an arc surface, so the corner is not too sharp and there is no need for subsequent edge grinding.

[0037] Furthermore, the outer peripheral surface of the second pressure wheel 22 is formed as the surface of the second pressure wheel 22.

[0038] Further, see Figure 2 The second pressing wheel 22 is tapered, so that the front circumference of the second pressing wheel 22 is larger than the rear circumference of the second pressing wheel 22. When pressing and shaping the flange, the second pressing wheel 22 uses the front circumference of the wheel surface for pressing, instead of pressing with the entire wheel surface. The outer side of the flange can be tapered downward along the second pressing wheel surface. Combined with the outer diameter of the first pressing wheel surface 211, it can be pressed and shaped into a straight edge flange, reducing the possibility of warping.

[0039] Further, see Figure 4 The second pressing wheel 22 has an arc surface; the outer diameter of the second pressing wheel 22 gradually increases from front to back. In this way, the arc surface of the first pressing wheel 211 and the arc surface of the second pressing wheel 22 cooperate to perform arc pressing and shaping of the flange, forming an arc flange.

[0040] Furthermore, a first wheel shaft can be provided on the first pressing seat 26, and the bottom end of the first wheel shaft is screwed to the first pressing seat 26 through a threaded section 212. The first pressing wheel 21 is rotatably engaged with the top end of the first wheel shaft. In this way, the height of the first wheel shaft on the first pressing seat 26 can be adjusted by the threaded rotational engagement between the threaded section 212 and the first pressing seat 26, so that the first pressing wheel 21 can extend into different height positions of the sheet metal workpiece, and the resulting flange size can be finely adjusted.

[0041] The height position of the first wheel shaft and the first pressure seat 26 is adjusted by the rotation of the threaded section 212. The adjustment accuracy is achieved by the engagement of the threaded ring, which makes the adjustment more accurate. Furthermore, the helical engagement of the threaded ring and the threaded groove restricts the direct axial movement of the machine itself, so that the height position is less likely to fall due to external force during the pressing process.

[0042] Furthermore, the bottom end of the first pressing seat 26 is provided with a first slide 261; the mounting bracket 25 is provided with a first slide rail; the first slide 261 and the first slide rail are slidably engaged. When the first pressing seat 26 slides with the mounting bracket 25, the sliding engagement of the first slide 261 and the first slide rail guides the first pressing wheel 21 on the first pressing wheel seat to move stably, thus ensuring stable movement.

[0043] Furthermore, a second slide block 271 is provided at the bottom end of the second pressing seat 27, and a second slide rail is provided on the mounting bracket 25. The second slide block 271 and the second slide rail are slidably engaged. When the second pressing seat 27 slides against the mounting bracket 25, the sliding engagement of the second slide block 271 and the second slide rail guides the second pressing wheel 22 on the second pressing wheel seat to move stably, thus ensuring stable movement.

[0044] 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.
