The rib expanding device 10 is vertical and comprises a frame 20, a jacking mechanism 30, a rib expanding module 40 and a conveying device 50. The rib expanding device 10 is vertical. The rib expanding module 40 is located above the jacking mechanism 30. The rib expansion device is vertical, and the axis of the barrel is vertical to the ground when the rib expansion device processes the barrel. Herein, inner means to be biased toward the center of the bead-expanding device 10, and outer means to be remote from the center of the bead-expanding device 10.

The frame 20 includes a lower frame 21, an upper frame 22, and a strut 23, the strut 23 being located between the lower frame 21 and the upper frame 22, the strut 23 connecting the lower frame 21 and the upper frame 22.

Fig. 2 and 3 are schematic views of a jacking mechanism 30, wherein the jacking mechanism 30 includes a jacking motor 31, a speed reducer 32, a transmission box 33, a synchronous pulley 34, a tensioning pulley 35, a synchronous belt 36, a lifting assembly 37, and a fixing member 38. The timing pulley 34 and the tension pulley 35 are disposed in the transmission case 33. The jack-up motor 31 is connected with a speed reducer 32, the speed reducer 32 is connected with a synchronous pulley 34, and the power of the jack-up motor 31 is transmitted to the synchronous pulley 34 through the speed reducer 32. The timing belt 36 bypasses the tension pulley 35 and the timing pulley 34, and the timing pulley 34 is engaged with the timing belt 36. The transmission case 33 includes a guide 331. The tensioning wheel 35 can enable the synchronous pulley 34 to be better meshed with the synchronous belt 36, and the transmission ratio is more accurate.

The fixing member 38 includes engaging teeth engaged with the timing belt 34, the timing belt 34 is located between the fixing member 38 and the lifting assembly 37, the fixing member 38 compresses the timing belt 36, the fixing member 38 is fixed to the lifting assembly 37, and the fixing member 38 fixes the timing belt 36 to the lifting assembly 37. By providing the engagement teeth on the fixing member 38, the fixing member 38 presses the timing belt 34, and the timing belt 34 can be more firmly fixed to the lifting assembly 37.

In this way, the jacking motor 31 provides power, the synchronous pulley 34 drives the synchronous belt 36 to enable the lifting assembly 37 to lift, and the jacking height of the jacking mechanism 30 can be adjusted by adjusting and controlling the rotation of the jacking motor 31. Meanwhile, the jacking mechanism 30 can have a high lifting speed, and the machining efficiency is improved.

The lifting assembly 37 includes a slide bar 371, a lifting plate 372, and a lifting limit assembly 373. The slide bar 371 includes a guide groove 374, and the guide groove 374 mates with the guide 331. The guide portion 331 is matched with the guide groove 374, so that the lifting motion of the sliding rod 371 is more stable, and the jacking of the jacking mechanism 30 is also more stable.

As shown in fig. 4, the jacking and limiting assembly 373 includes a limiting plate 375, a screw 376, an annular plate 377, and a spring 378. The limiting plate 375 is a limiting plate 372, and the limiting plate 375 is detachably contacted with the lifting plate 372. It should be noted that the separable type contact means that the jacking plate is subjected to a pre-tightening force, and is in contact with the limiting plate when no external force is applied, but the jacking plate and the limiting plate are separable when a certain amount of force is applied to the jacking plate, and the contact formed due to the pre-tightening force is called as the separable type contact. If the jacking plate 372 is rigidly fixed, when the rib expanding module 40 processes the barrel, the barrel body may be slightly inclined to cause the impact between the barrel body and the jacking plate 372, and meanwhile, the conveying error of the conveying mechanism of the assembly line also causes the impact, so that the jacking plate 372 and the limiting plate 375 are detachably contacted, the jacking plate 372 has a certain buffer, and the impact or the impact degree caused to the jacking plate 372 can be effectively reduced.

The jacking plate 372 comprises a main plate 396, a boss 397 and an annular wall 395, wherein the boss 397 is arranged on the outer side of the main plate 396, the boss 397 and the limiting plate 375 are arranged on the same side of the main plate 396, and the height of the boss 397 is larger than that of the limiting plate 375. The boss 397 is greater than the limiting plate 375 in height, so that the barrel can be effectively prevented from colliding with the limiting plate 375 when transported to the rib expanding device 10. The axis of the tub is perpendicular to the jacking plate 372.

As shown in fig. 5, the jacking plate 372 is provided with a groove 398, a magnetic body is arranged in the groove 398, and the grooves 398 are arranged in an arc shape. The diameter of the arc formed by the center of each groove 398 is consistent with the diameter range of the iron barrel curled edge, and it should be noted that the diameter range of the iron barrel curled edge is formed by the fact that the iron barrel is processed by the curling procedure, the diameters of the curled edges formed by the curling procedure are inconsistent, a diameter range is formed, and the fact that the diameter of the arc is consistent with the diameter range of the iron barrel means that the diameter of the arc falls into the diameter range of the curled edge. The slot 398 may open at the boss 397. The jacking speed of climbing mechanism 30 is faster, and sudden stop when climbing mechanism 30 with the bucket lifting to the settlement position, the ladle body can exist the risk of jumping away from jacking plate 372, and setting up in the setting of groove 398 and setting up of the magnetic body in the groove 398 can make the iron ladle lift in-process attract the iron ladle, reduces the iron ladle and breaks away from the risk of jacking plate 372. In addition, when the rib expansion module 40 expands the iron drum, the iron drum can be outwards protruded due to the fact that the drum body can be outwards protruded, at the moment, the rib expansion module 40 and the drum body can be temporarily separated from the jacking plate 372, at the moment, the magnetic body does not need to damage any structure for fixing the drum body, and the iron drum is not deformed due to the fact that larger force is generated between the drum body and the jacking mechanism 30, so that the iron drum is attracted by the magnetic body, and the iron drum has a considerable advantage. And the arc-shaped diameter formed by the centers of the grooves 398 is consistent with the diameter of the iron barrel, so that the magnetic body has better attraction effect on the iron barrel.

The annular wall 395 extends from the surface of the jacking plate 372 to a position away from the surface of the jacking plate 372, the jacking plate 372 is provided with a through hole, the annular wall 395 surrounds the through hole, and the inner diameter of the annular wall 395 is larger than the aperture of the through hole.

One end of the spring 378 abuts against the lift plate 372, and the other end abuts against the annular piece 377. Through setting up spring 378 and buffering jacking board 372, have advantages such as buffer structure is simple, life-span is longer, simultaneously, fixes with screw 376, and buffering inefficacy easy maintenance. The jacking plate 372 is provided with the annular wall 395, so that the spring 378 can be limited in the expansion process of the spring 378, the stability of the spring 378 is enhanced, and the play amplitude of the spring 378 in the expansion process is reduced.

The inner diameter of the ring 377 is larger than the large diameter of the threaded post 393 and smaller than the maximum outer diameter of the head 394. The maximum outer diameter of the head 394 refers to the distance of the center of the head from the point of the outermost periphery of the head. The ring-shaped sheet 377 is separated from the screw 376, the screw 376 is not required to be customized, and the ring-shaped sheet 377 can be a gasket with enough strength.

The second inner die 435 slides outward when the second section contacts the second inner die 435 and the contact portion moves in the direction of expanding the second section. The first section and the second section of the inner track die 426 can respectively drive the first inner die 434 and the second inner die 435 to slide outwards, and the switching of the first inner die 434 and the second inner die 435 only needs to adjust the position of the inner track die 435, so that the switching of the rib expansion patterns is convenient.
