Description

Technical Field

[0001] This utility model belongs to the technical field of flange production equipment, and in particular relates to a ring rolling mill for producing flanges. Background Technology

[0002] A ring rolling mill is a device used to manufacture ring-shaped metal parts. It applies pressure to the ring-shaped billet through rollers, causing it to undergo plastic deformation, gradually reducing the wall thickness and increasing the diameter, and finally forming a ring-shaped workpiece of the required size and shape.

[0003] The existing ring rolling mill for producing flanges supports the two sides of the ring billet at an angle downwards. During rolling, as the billet diameter increases, the rotational stability of the billet weakens, and the billet is prone to deformation due to rotation and gravity. Utility Model Content

[0004] The technical problem to be solved by this utility model is to enhance the stability of the rolling of ring workpieces during flange processing.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is as follows: a ring rolling mill for producing flanges, including a base and an upright extending upward from the upper wall of the base, and also including a support plate, a drive wheel, a support wheel and a pressing wheel. The support plate is fixedly connected to the upper part of the upright, and the drive wheel is rotatably connected to the middle of the end face of the support plate.

[0006] The end face of the support plate has a sliding groove, which is symmetrically distributed around the drive wheel. A slider is slidably installed in the sliding groove, and the slider is adjusted by moving along the length of the sliding groove through the drive assembly.

[0007] The support wheel is adjusted by sliding along the length of the groove via a slider, and the support wheel is located on the same side as the drive wheel;

[0008] A connecting plate is fixedly connected to the upper wall of the support plate, and the pressing wheel is movably connected to the bottom of the connecting plate through an adjustment component and is located above the drive wheel.

[0009] Furthermore, a rotary motor is installed at the end of the support plate away from the drive wheel, and the rotary motor is fixedly connected to one end of the drive wheel; a slide rod is fixedly connected between the opposite sidewalls of the slide groove, the slide rod passes through the slider and is slidably connected to the slider.

[0010] Furthermore, the drive assembly includes a support frame, a rotating rod, and a connecting ring. The support frame is fixedly installed on the end of the support plate away from the drive wheel. One end of the rotating rod is rotatably connected to the end face of the support plate, and the other end of the rotating rod is rotatably connected to the middle of the support frame. The connecting ring is threaded to the outer wall of the rotating rod, and a support rod is hinged between the connecting ring and the slider.

[0011] Furthermore, a second rotary motor is installed on the side of the support frame away from the rotating rod, and the output end of the second rotary motor is fixedly connected to one end of the rotating rod.

[0012] Furthermore, the adjustment assembly includes a cylinder and a connecting frame. The cylinder is installed at the center of the upper wall of the connecting plate, and the telescopic end of the cylinder extends through the connecting plate to the bottom of the connecting plate. The connecting frame is fixedly connected to the telescopic end of the cylinder, and the pressing wheel is rotatably connected between the opposite inner sidewalls of the support frame.

[0013] Furthermore, fixing holes are provided at the corners of the base.

[0014] The beneficial effects of this utility model after adopting the above structure are as follows: For the rolling of annular workpieces during flange production, the drive assembly is used to move the symmetrical slider and support wheel along the radial direction of the annular workpiece. During the rotational rolling process, the adjustment assembly pushes the pressing wheel down and closes it to the support wheel to roll the annular workpiece. As the diameter of the annular workpiece increases, the upper drive wheel and the two sides of the pressing wheel of the annular workpiece are supported, and the support width is increased to avoid deformation of the annular workpiece due to gravity. It is suitable for supporting annular workpieces of different diameters. Attached Figure Description

[0021] like Figure 1-4 As shown, a ring rolling mill for producing flanges includes a base 1 and an upright 2 extending upward from the upper wall of the base 1. It also includes a support plate 3, a drive wheel 4, a support wheel 5, and a pressing wheel 6. The support plate 3 is fixedly connected to the upper part of the upright 2. The drive wheel 4 is rotatably connected to the middle of the end face of the support plate 3. A groove 7 is formed on the end face of the support plate 3, symmetrically distributed around the drive wheel 4. A slider 8 slides within the groove 7. The slider 8 is adjusted by moving along the length of the groove 7 via a drive assembly 9. The support wheel 5 is adjusted by sliding along the length of the groove 7 via the slider 8. The support wheel 5 is located on the same side as the drive wheel 4. A connecting plate 10 is fixedly connected to the upper wall of the support plate 3. The pressing wheel 6 is movably connected to the bottom of the connecting plate 10 via an adjusting assembly 11 and is located above the drive wheel 4. A rotary motor 12 is installed at the end of the support plate 3 away from the drive wheel 4. The rotary motor 12 is fixedly connected to one end of the drive wheel 4. Sliding rollers are fixedly connected between the opposite side walls of the groove 7. Rod 13 and slide rod 13 pass through slider 8 and are slidably connected to slider 8. Fixing holes 21 are opened at the corners of the base 1. The base 1 is bolted and positioned through fixing holes 21. The upright rod 2 increases the height of the support plate 3. In the initial state, the symmetrical support wheels 5 are close to each other. The annular workpiece is placed on the outside of the symmetrical support wheels 5 and drive wheels 4. The drive wheels 4 are driven to rotate by the rotary motor 12, so that the annular workpiece rotates. The pressing wheel 6 is supported downward by the adjusting component 11. The pressing wheel 6 and drive wheels 4 are used to roll the side wall of the annular workpiece. The two side support wheels 5 support the upper two sides of the annular workpiece. As the annular workpiece rotates and is rolled, the wall thickness becomes thinner, the diameter of the annular workpiece increases and the center moves downward. The slider 8 is pushed to move in the groove 7 by the drive component 9, so that the symmetrical support wheels 5 move away from each other. The symmetrical support wheels 5 support the upper part of the annular workpiece, which increases the stability of the rotation rolling and prevents the annular workpiece from sagging and deforming due to gravity.

[0022] like Figure 2-4 As shown, in order to achieve the width adjustment of the symmetrical support wheel 5, the drive assembly 9 includes a support frame 14, a rotating rod 15, and a connecting ring 16. The support frame 14 is fixedly installed on the end of the support plate 3 away from the drive wheel 4. One end of the rotating rod 15 is rotatably connected to the end face of the support plate 3, and the other end of the rotating rod 15 is rotatably connected to the middle of the support frame 14. The connecting ring 16 is threadedly connected to the outer wall of the rotating rod 15. A support rod 17 is hinged between the connecting ring 16 and the slider 8. A second rotary motor 18 is installed on the side of the support frame 14 away from the rotating rod 15. The output end of the second rotary motor 18 is fixedly connected to one end of the rotating rod 15, driving the second rotary motor 18 to rotate in the forward direction. The rotating rod 15 pushes the connecting ring 16 to move to one side of the support plate 3 through the thread. At the same time, the support rod 17 pushes the slider 8 to slide along the slide groove 7, so that the symmetrical support wheel 5 is spread apart, and the annular workpiece is supported on both sides of the drive wheel 4 to expand the support width.

[0023] like Figure 3 and Figure 4 As shown, in order to achieve the downward movement of the pressing roller 6 and the rolling of the annular workpiece, the adjusting assembly 11 includes a cylinder 19 and a connecting frame 20. The cylinder 19 is installed at the center of the upper wall of the connecting plate 10. The telescopic end of the cylinder 19 extends through the connecting plate 10 to the bottom of the connecting plate 10. The connecting frame 20 is fixedly connected to the telescopic end of the cylinder 19. The pressing roller 6 is rotatably connected between the opposite inner side walls of the support frame 14. The cylinder 19 is driven to move downward. The telescopic end of the cylinder 19 pushes the connecting frame 20 to move downward and drives the pressing roller 6 to move closer to the driving wheel 4, squeezing the side wall of the annular workpiece. As the annular workpiece rotates, rolling is achieved.

[0024] In actual use, the operator fixes the device and uses bolts to install it by inserting them through the fixing holes 21 at the corner of the base 1. In the initial state, the symmetrical support wheels 5 are close to each other and located below the slide groove 7. The ring-shaped workpiece is fed and fitted on the outside of the symmetrical support wheels 5 and the drive wheel 4.

[0025] During rolling, the telescopic end of the drive cylinder 19 extends, pushing the connecting frame 20 downward to fit against the upper outer wall of the annular workpiece, squeezing the side wall of the annular workpiece. The drive rotary motor 12 rotates, and the drive wheel 4 drives the annular workpiece to rotate. The two support wheels 5 support the upper sides of the annular workpiece. As the annular workpiece rotates and is rolled, the wall thickness becomes thinner, the diameter of the annular workpiece increases, and the center of the circle moves downward. The drive rotary motor 18 rotates in the forward direction, and the rotating rod 15 pushes the connecting ring 16 to one side of the support plate 3 through the thread. At the same time, the support rod 17 pushes the slider 8 to slide along the slide groove 7, so that the symmetrical support wheels 5 are spread apart, and the inner upper wall of the annular workpiece is supported on both sides of the drive wheel 4, expanding the support width for the annular workpiece, increasing the stability of the rotary rolling, and preventing the annular workpiece from sagging and deforming due to gravity.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
