At the first bead expanding / rolling station and the second bead expanding / rolling station, it can be selected whether the bead expanding mechanism 4 or the bead rolling mechanism 6 is working. In this embodiment, the first bead expanding / rolling station adopts the bead expanding mechanism 4 to work, and the second bead expanding / rolling station adopts the bead rolling mechanism 6 to work. Of course, the bead expanding mechanism 4 and the bead rolling mechanism 6 can be switched.

[0031] The following is a detailed description of each organization.

The innermost side of the lower end of the winding roller is located in the three-dimensional space of the positioning disc, so that the contact between the barrel mouth and the winding roller is an arc contact, that is, the cutting edge of the barrel body is directly bent, and the cutting edge surface of the barrel body is directly wrapped inside the curling edge, ensuring that the curling edge is smooth, and the barrel mouth is curled while the winding roller rotates and the barrel body is slowly lifted by rotating parallel to the barrel mouth.

[0035] like Figure 1-3 As shown, the tendon expansion mechanism 4 in the production line includes a tendon expansion frame 40, a tendon expansion power system, a tendon expansion transmission system, and a tendon expansion block. The tendon expansion power system is arranged on the tendon expansion frame 40, the tendon expansion transmission system is located between the tendon expansion power system and the tendon expansion block, the tendon expansion block is sleeved on the outside of the tendon expansion transmission system, and the tendon expansion power system pushes the tendon expansion block to expand outward through the tendon expansion transmission system to expand the barrel wall of the steel lifting bucket.

The first tendon expansion adjustment block 41 is sleeved on the outside of the tendon expansion transmission system, and the second tendon expansion adjustment block 42 is movably sleeved on the outside of the first tendon expansion adjustment block 41. The first tendon expansion adjustment block 41 is provided with a first tendon component 410, and the second tendon expansion adjustment block 42 is provided with a second tendon component 420. The tendon expansion block adjusts the distance between the first tendon component 410 and the second tendon component 420 by moving the second tendon expansion adjustment block 42, so as to adjust the spacing of the tendon lines of the steel lifting bucket.

[0036] The reinforcement block also includes a reinforcement locking structure for moving and locking the first reinforcement adjustment block 41 and the second reinforcement adjustment block 42. The reinforcement locking structure includes a reinforcement fixing hole group and reinforcement fasteners provided on the first reinforcement adjustment block 41 and the second reinforcement adjustment block 42, and the first reinforcement adjustment block 41 and the second reinforcement adjustment block 42 are fixed to each other through the reinforcement fixing hole group and the reinforcement fasteners. The first reinforcement adjustment block 41 and the second reinforcement adjustment block 42 are respectively provided with a plurality of first reinforcement fixing holes 411 and second reinforcement fixing holes 421, and the first reinforcement fixing holes 411 and the second reinforcement fixing holes 421 are distributed along the moving direction of the second reinforcement adjustment block 42, and the first reinforcement adjustment block 41 and the second reinforcement adjustment block 42 can be fixed through reinforcement fasteners at the first reinforcement fixing holes 411 and the second reinforcement fixing holes 421 at different positions. The first and second tensioning rib fixing holes 411 and 421 distributed along the moving direction of the second tensioning rib adjusting block 42 constitute a tensioning rib fixing hole group. Multiple groups of such tensioning rib fixing hole groups are provided on the circumference of the first and second tensioning rib adjusting blocks 41 and 42 .

[0037] The tendon expansion power system includes a tendon expansion power source, a tendon expansion power shaft 43 movable along its axial direction, and a tendon expansion power inclined block 44. The tendon expansion power inclined block 44 is fixedly connected to one end of the tendon expansion power shaft 43, and the tendon expansion power source is connected to the other end of the tendon expansion power shaft 43. The tendon expansion power inclined block 44 has a tendon expansion sliding inclined surface 440 inclined from top to bottom in a direction away from the tendon expansion transmission system, and the tendon expansion power inclined block 44 is slidably matched with the tendon expansion transmission system. The tendon expansion transmission system includes a tendon expansion transmission inclined block 45, and the tendon expansion transmission inclined block 45 has a tendon expansion matching inclined surface 450 matched with the tendon expansion sliding inclined surface 440.

The tendon expansion transmission limit shaft 46 is parallel to the tendon expansion power shaft 43, and the tendon expansion transmission inclined block 45 passes through the tendon expansion transmission limit shaft 46. The tendon expansion transmission inclined block 45 is provided with a tendon expansion shaft hole 47, and a tendon expansion transmission limit shaft 46 is arranged in the tendon expansion shaft hole 47, and there is a gap between the tendon expansion transmission limit shaft 46 and the tendon expansion shaft hole 47 for the tendon expansion transmission inclined block 45 to move. The tendon expansion transmission inclined block 45 can push the first tendon expansion adjustment block 41 and the second tendon expansion adjustment block 42 to expand the steel bucket tendons when it expands outward on the tendon expansion transmission guide plate 48, and at the same time, the tendon expansion transmission limit shaft 46 can limit the moving distance of the tendon expansion transmission inclined block 45, and usually the movable gap in the tendon expansion shaft hole 47 is the protruding length of the tendon line.

[0038] After the conveyor belt 7 conveys the steel lifting bucket to the first reinforcement / rolling station, the steel lifting bucket is sleeved on the outside of the second reinforcement adjustment block 42, and the reinforcement power source drives the reinforcement power shaft 43 to move downward, driving the reinforcement power inclined block 44 to move downward, and through the inclined sliding cooperation between the reinforcement power inclined block 44 and the reinforcement transmission inclined block 45, the reinforcement transmission inclined block 45 moves outward, pushing the first reinforcement adjustment block 41 and the second reinforcement adjustment block 42 to expand outward, thereby realizing the reinforcement of the steel lifting bucket.

[0039] like Figure 1 As shown, the ear welding mechanism 5 in the production line can adopt the patent with publication number CN209206793U. After the conveyor belt 7 conveys the steel lifting bucket to the ear welding station, the steel lifting bucket enters the ear welding holder, and the ear welding lifting assembly drives the ear welding holder to rise, so that the position of the corresponding welding electric ear of the steel lifting bucket covers the inner head area of ​​the internal top tank part, and the driving motor rotates the energized ear cam to perform rotational motion; the rotation of the ear cam drives the electrode swing blocks on both sides to move, so that the electrode parts of the external electrodes of the ear on both sides move inward, and the internal top tank part opens to support the inner wall of the steel lifting bucket, so that after the external electrodes of the ear are energized, the tank ear and the steel lifting bucket are welded; the tank ear is output to the corresponding position of the inner end of the electrode part through the ear delivery system; after the welding is completed, each component is reset, waiting for the next steel lifting bucket to enter the ear welding station for periodic welding.

[0040] like Figure 1 ,4 As shown, the bead rolling mechanism 6 in the production line includes a bead rolling frame 60, a bead rolling inner mold system arranged on the bead rolling frame 60, a bead rolling outer mold system, a bead rolling power drive system for driving the bead rolling inner mold system and the bead rolling outer mold system, and a bead rolling elastic reset system for automatically restoring the bead rolling mechanism 6 to its initial state.
