Description

Technical Field

[0001] This utility model relates to the field of flanging machines, specifically to a flanging structure for a flanging machine. Background Technology

[0002] In the field of shock absorber manufacturing, it is usually necessary to flange the opening of the shock absorber outer cylinder. Flanging increases the structural strength and rigidity of the outer cylinder opening. Furthermore, since an end cap needs to be installed at the opening, flanging provides a positioning reference for the end cap, facilitating quick and accurate centering and alignment during assembly. In a flanging machine, the flanging structure is a key functional component. For example, Chinese patent CN114054627B provides a flanging machine that includes a worktable, a rotating assembly, inner rollers, outer rollers, a stroke control assembly, and a clamping assembly. The rotating component has a hub mounted on its output end, which drives the hub to rotate. The output end of the clamping component abuts against the upper surface of the hub to clamp and limit the hub. The outer wall of the inner roller abuts against the inner wall of the inner roller, and a flange groove is provided around the upper edge of the inner roller. The stroke control component drives the outer roller to move forward and abut against the outer wall of the hub. The outer roller pushes the lower edge of the hub to fold into the flange groove. Such a flange machine requires an inner roller to be set inside the workpiece to cooperate with the flange operation. It is only suitable for flange workpieces with large openings, such as hubs. It is difficult to flange workpieces with small openings, such as shock absorber outer cylinders. Utility Model Content

[0003] The purpose of this utility model is to provide a flanging structure for a flanging machine, which can effectively flanging the outer cylinder of a shock absorber. The flanging process is carried out twice at the opening of the outer cylinder, which can reduce the deformation resistance of the outer cylinder material, reduce the risk of cracking during flanging, and at the same time reduce the instantaneous load on the flanging wheel, thereby improving its service life.

[0004] To achieve the above objectives, this utility model provides a flanging structure for a flanging machine, the flanging structure including a frame, a drive cylinder mounted on the frame, a sliding seat slidably mounted on the frame, a drive assembly mounted on the sliding seat, a flipping frame mounted on the sliding seat, and a flanging wheel mounted on the flipping frame;

[0005] The piston rod of the drive cylinder is connected to the sliding seat;

[0006] The drive component can drive the tilting frame to rotate;

[0007] The upper end of the flanging wheel extends outward to form an annular portion, and the annular portion and the flanging wheel are connected to form a beveled structure.

[0008] Preferably, a 45° angle is formed between the inclined surface structure and the flanging wheel.

[0009] Preferably, the drive assembly includes a hydraulic cylinder movably mounted on a sliding seat, a connector connected to the piston rod of the hydraulic cylinder, and a rotating arm hinged to the connector;

[0010] The rotating arm is connected to the tilting frame.

[0011] Preferably, the sliding seat is provided with a bearing, and both ends of the tilting frame are at least partially rotatably disposed within the bearing.

[0012] Preferably, a limiting seat is provided in the sliding seat near the rotating arm, and an inclined surface is formed on the side of the limiting seat facing the rotating arm; a positioning post is provided on the inclined surface.

[0013] Beneficial effects: This utility model provides a flanging structure for a flanging machine. The flanging structure includes a frame, a drive cylinder mounted on the frame, a sliding seat slidably mounted on the frame, a drive assembly mounted on the sliding seat, a flipping frame mounted on the sliding seat, and a flanging wheel mounted on the flipping frame. The piston rod of the drive cylinder is connected to the sliding seat. The drive assembly can drive the flipping frame to rotate. The upper end of the flanging wheel extends outward to form an annular portion, and the annular portion and the flanging wheel are connected to form a beveled structure. This flanging structure is applied to a flanging machine, which includes a support frame. The support frame has a tooling structure for positioning the outer cylinder of the shock absorber. This tooling structure can drive the outer cylinder to rotate and move vertically. Initially, the upper surface of the flanging wheel in the flanging structure is horizontal. When the outer cylinder moves vertically to the edge of the flanging wheel, a drive cylinder drives the sliding seat to move horizontally. The horizontal displacement of the flanging wheel presses against the opening of the outer cylinder, causing the opening to be pressed inward at a certain angle, such as 45 degrees. Then, a drive assembly drives the flanging wheel to rotate towards the outer cylinder at a certain angle, such as 45 degrees. This flanging structure can perform flanging treatment on the opening of the outer cylinder in two stages, which can reduce the deformation resistance of the outer cylinder material, reduce the risk of flanging cracking, and at the same time, reduce the instantaneous load on the flanging wheel, thus improving its service life.

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] like Figure 1-5 As shown: This utility model provides a flanging structure for a flanging machine. The flanging structure includes a frame 1, a drive cylinder 15 mounted on the frame 1, a sliding seat 14 slidably mounted on the frame 1, a drive assembly mounted on the sliding seat 14, a flipping frame 2 mounted on the sliding seat 14, and a flanging wheel 3 mounted on the flipping frame 2. The piston rod of the drive cylinder 15 is connected to the sliding seat 14. The drive assembly can drive the flipping frame 2 to rotate. The upper end of the flanging wheel 3 extends outward to form an annular portion 5, and an inclined surface structure 11 is formed at the junction of the annular portion 5 and the flanging wheel 3.

[0025] like Figure 5As shown, this flanging structure is applied to a flanging machine, which includes a support frame. The support frame is equipped with a tooling structure 13 for positioning the outer cylinder 12 of the shock absorber. The tooling structure 13 can drive the outer cylinder 12 to rotate and move vertically. In the initial state, the upper end face of the flanging wheel 3 in the flanging structure is horizontal. When the outer cylinder 12 moves vertically to the edge of the flanging wheel, the driving cylinder 15 drives the sliding seat 14 to move horizontally. The horizontal displacement of the flanging wheel 3 squeezes the opening of the outer cylinder, so that the opening is squeezed inward to form a certain angle, such as 45 degrees. Then, the driving component drives the flanging wheel 3 to rotate towards the outer cylinder 12 at a certain angle, such as 45 degrees. This flanging structure can perform flanging treatment on the opening of the outer cylinder in two stages, which can reduce the deformation resistance of the outer cylinder material, reduce the risk of flanging cracking, and at the same time, reduce the instantaneous load on the flanging wheel and improve its service life.

[0026] In a preferred embodiment of this utility model, a 45° angle is formed between the inclined structure 11 and the flanging wheel 3. When the outer cylinder 12 moves upward to the edge of the flanging wheel, the driving cylinder 15 drives the sliding seat 14 to move horizontally. The horizontal movement of the flanging wheel 3 presses the opening of the outer cylinder, causing the opening to be pressed inward to form a 45° angle. Then, the flanging wheel 3 is used to flip the 45° angle so that the opening of the outer cylinder 12 is turned inward by 90°.

[0027] In a preferred embodiment of this utility model, the driving assembly includes a hydraulic cylinder 4 movably mounted on a sliding seat 14, a connecting member 10 connected to the piston rod of the hydraulic cylinder 4, and a rotating arm 9 hinged to the connecting member 10; the rotating arm 9 is connected to the tilting frame 2. By activating the hydraulic cylinder, the tilting frame 2 can be tilted via the connecting member 10 and the rotating arm 9.

[0028] In a preferred embodiment of the present invention, in order to make the flipping frame 2 flip more smoothly on the sliding seat 14, the sliding seat 14 is provided with a bearing 6, and at least part of both ends of the flipping frame 2 are rotatably disposed in the bearing 6.

[0029] In a preferred embodiment of this utility model, in order to limit the flipping angle of the flipping frame 2, a limiting seat 7 is provided in the sliding seat 14 near the rotating arm 9, and an inclined surface is formed on the side of the limiting seat 7 facing the rotating arm 9; a positioning post 8 is provided on the inclined surface. When the flipping frame 2 flips to a certain angle, it can contact the positioning post 8, thereby preventing the rotating arm 9 from continuing to flip.

[0030] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0031] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0032] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
