[0036] Example 1

[0037] like Figure 2-8 As shown, this utility model provides a narrow flow channel annular part roll forming tool, including a support plate 2, a forming concave wheel 4, a forming cam I 5, a drive shaft 6, a pressure block 8, a rocker arm 9, a pressure rod 10, a forming cam II 11, a push rod 12 and a driven wheel 13;

[0038] The upper end of the support plate 2 is provided with a sliding groove, and a slider 7 that can slide up and down along the sliding groove is installed in the sliding groove. The forming cam I 5 is installed on the slider 7 through the drive shaft 6. The rocker arm 9 is fixedly connected to the drive shaft 6 by a pin key. The rocker arm 9 is used as a power input to control the drive shaft 6 to drive the forming cam I 5 to rotate.

[0039] The support plate 2 is also provided with a mounting hole located below the slide groove and two transverse slide grooves located on both sides of the mounting hole; the forming concave wheel 4 is rotatably mounted in the mounting hole via the driven shaft 13; the forming cam II 11 is mounted in any one of the transverse slide grooves via the mounting shaft;

[0040] The profile of the narrow flow channel annular part has a flow channel structure on its side; the side of the forming concave wheel 4 is provided with a groove structure I that matches the inner side of the profile; the sides of the forming cam I 5 and the forming cam II 11 are each provided with a groove structure II that matches the shape of the flow channel structure, and the groove structure II is provided with a protrusion structure that can be embedded in the flow channel of the flow channel structure, and the groove structure II can be interlocked with the flow channel structure; the profile can be installed between the forming concave wheel 4, the forming cam I 5 and the forming cam II 11, the flow channel structure of the profile is embedded in the groove structure II of the forming cam I 5 and the forming cam II 11, and the inner side is embedded in the groove structure I of the forming concave wheel 4;

[0041] The pressure block 8 is installed in the upper opening of the slide groove and is fixedly connected to the support plate 2; the pressure rod 10 passes through the pressure block 8 from above and is connected to the pressure block 8 by thread. The pressure rod 10 is used to control the slider 7 to drive the forming cam I5 downward by rotating the thread and pressing it against the slider 7, thereby adjusting the gap between the forming cam I5 and the forming concave wheel 4 to press the profile and ensure the stability of the profile clamping.

[0042] The support plate 2 has a through hole on each side, and the two through holes are respectively connected to the two transverse sliding grooves. The push rod 12 is used to pass through the through hole and extend into the transverse sliding groove to control the mounting shaft to drive the forming cam II 11 to move forward in the transverse sliding groove, thereby adjusting the distance between the forming cam II 11 and the forming concave wheel 4 to adjust the size of the narrow flow channel annular part, while ensuring the stability of the profile clamping.

[0043] Furthermore, it also includes a workbench 1, on which the support plate 2 is fixedly installed.

[0044] Furthermore, the slider 7 is installed in the slide groove through grooves on both sides that match the sides of the slide groove; the slider 7 has an axial mounting hole in the center for installing the drive shaft 6.

[0045] Furthermore, the drive shaft 6 passes through the axial mounting hole, with the shaped cam I5 mounted at one end and the rocker arm 9 connected at the other end.

[0046] Furthermore, the slider 7 and the groove are in a transition fit to ensure that the gap is not too large, which would cause the forming cam I5 to deviate, or that the gap is too small, which would cause it to jam.

[0047] Furthermore, the drive shaft 6 and the driven shaft 13 are respectively mounted in the axial mounting hole and the mounting hole through two bearings, so as to achieve axial rotation balance after the forming cam I5 and the forming concave wheel 4 are installed, control the precision of the forming wheel during the working process, and ensure that the workpiece does not deform in the forming wheel.

[0048] The components of the narrow-channel annular roll forming tool of this utility model are made of high-quality alloy materials, which can achieve long service life, wear resistance and rust prevention.

[0049] Specific work process:

[0050] The blank for producing narrow-channel annular components (sealing rings) is... Figure 1 The long straight profile with the cross-sectional structure (flow channel structure) shown is placed between the forming cam I 5 and the forming concave wheel 4 of the roll forming tool described in this application. The profile is inserted at an angle into the groove structure II on the side of the forming cam II 11, so that the flow channel structure of the profile is embedded in the groove structure II of the forming cam I 5 and the forming cam II 11. On the other side, the groove structure I of the forming concave wheel 4 is embedded. As the profile is conveyed forward, the forming cam II 11 is fed forward by the push rod 12, which extrudes and deforms the profile, gradually changing it from straight to curved until a circular workpiece is obtained. At the same time, the diameter of the circular workpiece is adjusted by adjusting the distance between the forming cam II 11 and the forming concave wheel 4.

[0051] The narrow-channel annular part roll forming tool of this utility model uses the groove structure I and groove structure II on the three forming wheels to clamp and fix the profile of the narrow-channel annular part between the three forming wheels. The groove structure I and groove structure II can completely fit the outer contour structure of the product, ensuring that the bending section can be completely included inside the groove structure I and groove structure II during the forming process, avoiding bending deformation during the forming process, which would cause wrinkles on the sealing surface and lead to failure.

[0052] The split forming roller can reserve space for contouring and limiting avoidance (forming wheel groove avoidance). The forming concave roller 4, forming cam II 11 and forming cam I 5 are respectively installed in the mounting hole, transverse slide groove and slide groove, which are equivalent to the fixed wheel (inner wheel), the progressive wheel (outer wheel) and the extrusion wheel (outer wheel). The position of forming cam II 11 and forming cam I 5 in the corresponding slide groove is adjusted by the top rod 12 and the pressure rod 10 to adjust the fit clearance between the three forming wheels, thereby realizing the round forming of the narrow flow channel solid. The diameter of the sealing ring of different specifications and sizes can be controlled by controlling the feed amount of forming cam II 11.

[0053] The narrow-channel annular profile is extruded and shaped by the continuous feeding of the progressive rollers, forming an arc. The feed amount of the progressive rollers controls the size of the arc. At the same time, the three rollers work together to control the roundness during the extrusion rotation. The narrow channel cross-sectional structure is restricted by the contoured groove structure to ensure the integrity of the plane after forming.

[0054] The narrow-channel annular part roll forming tool described in this utility model is easy to disassemble, simple to operate, and highly efficient. It requires no professional skills training and can be connected to a servo motor to improve work efficiency and ensure stable forming.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
