Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal gasket processing equipment, specifically to an automatic edge-rolling device for metal gaskets. Background Technology
[0002] With the rapid development of industries such as machinery manufacturing and pipeline connection, metal gaskets are widely used in sealing connections of various equipment due to their excellent sealing performance and structural stability. To improve the edge smoothness of metal gaskets, prevent scratches to operators or sealing surfaces during installation, and enhance the overall structural strength of the gaskets, the edges of the metal gaskets need to be rolled. Currently, most metal gasket edge rolling operations on the market use semi-automatic equipment or manual assistance. Semi-automatic equipment often requires manual adjustment of the metal gasket's position to ensure precise alignment between the rolling wheel and the gasket edge. This is not only cumbersome and time-consuming, but also prone to inconsistent rolling precision due to human positioning errors, affecting the gasket's sealing effect and product qualification rate.
[0003] Therefore, it is necessary to invent an automatic edge-rolling device for metal gaskets to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an automatic edge-rolling device for metal gaskets. The device achieves automatic positioning of metal gaskets through a positioning mechanism and is used in conjunction with a calibration mechanism to accurately calibrate gaskets of different sizes, thereby solving the problems of cumbersome positioning and low accuracy in existing metal gasket edge-rolling equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic edge-rolling device for metal gaskets, comprising a base plate, a support plate fixedly connected to the top of the base plate via a pillar, a placement platform slidably connected to the top of the support plate via a sliding column, a positioning mechanism fixedly connected to the bottom of the placement platform, a rotating motor fixedly connected to the top of the support plate, the output shaft of the rotating motor fixedly connected to the bottom of the positioning mechanism, a calibration mechanism provided on the top of the base plate, a bracket fixedly connected to the rear end of the top of the base plate, an electric push cylinder fixedly connected to the bottom of the bracket, a top plate fixedly connected to the bottom end of the electric push cylinder, a slidably connected rear side of the top plate to the bracket, an electric push rod fixedly connected to the bottom of the top plate via a mounting block, a mounting base fixedly connected to one end of the electric push rod, a top of the mounting base slidably connected to the bottom of the top plate, and an edge-rolling wheel fixedly mounted on the bottom of the mounting base.

A positioning pin 43 is fixedly connected to the top of the sliding disk 42. The top of the positioning pin 43 passes through the placement platform 3 and extends to the top of the placement platform 3. A positioning spring 44 is fixedly connected between the bottom of the sliding disk 42 and the bottom of the inner wall of the positioning cylinder 41. Under the elastic action of the positioning spring 44, the positioning pin 43 is movable. When fixed, the fixing plate 14 moves downward, driving the positioning pin 43 to move downward until the fixing plate 14 contacts the metal gasket, thereby fixing the metal gasket. The calibration mechanism 6 includes two support blocks 61. The bottoms of the two support blocks 61 are fixedly connected to the top sides of the base plate 1 respectively. A lead screw 62 is rotatably connected between the opposite sides of the two support blocks 61. A drive motor 63 for driving the lead screw 62 to rotate is fixedly installed on one side of one of the support blocks 61. Moving blocks 64 are threadedly connected to both sides of the surface of the lead screw 62. The bottom of the moving blocks 64 is slidably connected to the top of the base plate 1. A support plate 65 is fixedly connected to the top of the moving blocks 64. The lead screw 62 has threads in opposite directions on its surface, and the drive motor 63 is a three-phase asynchronous AC motor; A sliding block 66 is slidably connected to the top of one side of the support plate 65. A calibration wheel 67 is rotatably connected to the top of the sliding block 66 via a rotating frame. A support 68 is fixedly connected to the bottom of one side of the support plate 65. A return spring 69 is fixedly connected between the top of the support 68 and the bottom of the sliding block 66. A connecting plate 610 is fixedly connected to one side of the sliding block 66. Pressing rods 15 that cooperate with the connecting plate 610 are fixedly connected to both sides of the bottom of the top plate 9. The electric push cylinder 8 pushes the top plate 9 to slide downward along the bracket 7. The top plate 9 drives the fixed plate 14, electric push rod 10, mounting base 11, edge rolling wheel 12 and pressing rod 15 to descend synchronously. When the pressing rod 15 contacts the connecting plate 610 and continues to press downward, the connecting plate 610 drives the sliding block 66 to slide downward along the support plate 65. The return spring 69 is compressed, and the sliding block 66 drives the calibration wheel 67 to move downward until the calibration wheel 67 disengages from the edge of the metal pad. All built-in electrical components are connected to the PLC controller.
[0017] The working principle of this practical application is as follows: First, place the metal pad to be rolled on the placement table 3, aligning the center hole on the metal pad with the positioning pin 43 to complete the initial positioning of the metal pad; then, according to the diameter of the metal pad, start the drive motor 63, which drives the lead screw 62 to rotate. The moving blocks 64 on both sides of the lead screw 62 move synchronously towards the placement table 3 under the action of the thread until the two calibration wheels 67 contact the edge of the metal pad to calibrate the metal pad and make it in the middle position. Then, turn off the drive motor 63. Next, the electric push cylinder 8 is activated, which pushes the top plate 9 to slide downward along the bracket 7. The top plate 9 drives the fixed plate 14, electric push rod 10, mounting base 11, edge rolling wheel 12 and pressing rod 15 to descend synchronously. When the pressing rod 15 contacts the connecting plate 610 and continues to press downward, the connecting plate 610 drives the sliding block 66 to slide downward along the support plate 65. The return spring 69 is compressed, and the sliding block 66 drives the calibration wheel 67 to move downward until the calibration wheel 67 disengages from the edge of the metal pad. At the same time, the fixed plate 14 also makes tight contact with the top of the metal pad, realizing the pressing and fixing of the metal pad. Then, the electric push cylinder 8 is closed. Then, start the electric push rod 10. The electric push rod 10 pushes the mounting base 11 to slide along the bottom of the top plate 9. The mounting base 11 drives the edge-rolling wheel 12 to move towards the edge of the metal pad until the edge-rolling wheel 12 contacts the edge of the metal pad and reaches the preset edge-rolling pressure. Then, turn off the electric push rod 10. Finally, start the rotating motor 5. The rotating motor 5 drives the positioning cylinder 41, sliding disk 42, positioning pin 43, placement platform 3 and metal pad to rotate synchronously. During the rotation of the metal pad, the edge-rolling wheel 12 continuously rolls its edge. After the edge-rolling is completed, turn off the rotating motor 5 in sequence, start the electric push rod 10 to drive the edge-rolling wheel 12 to reset, start the electric push cylinder 8 to drive the top plate 9 and related components to rise, and press the rod 15 to disengage from the connecting plate 610. Under the action of the reset spring 69, the sliding block 66 and the calibration wheel 67 reset. Finally, the edge-rolled metal pad can be removed from the placement platform 3.
