Description

Technical Field

[0001] This utility model relates to the field of steel bucket production technology, and more specifically, to a rib expansion mechanism for an automatic steel bucket production line. Background Technology

[0002] Steel drums are a traditional container, holding a significant place among them. Their function has evolved from temporary storage to modern industrial, retail, and transport packaging. During production, to enhance the strength of the drum, an expansion rib is formed within it. This expansion is achieved by inserting an expansion rib mold into the drum body, followed by the use of a cylinder and motor to inflate and rotate the rib. The size of the expansion rib is determined by a fixed mold, and this process requires changing the mold for different drum types, making it time-consuming and cumbersome. Therefore, we propose an expansion rib mechanism for an automated steel drum production line. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rib expansion mechanism for an automatic steel bucket production line to solve the technical problem of time-consuming and troublesome replacement process of the current rib expansion mold.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rib-expanding mechanism for an automatic steel bucket production line, comprising a fixed base, a plurality of rib-expanding plates on the top of the fixed base, the plurality of rib-expanding plates having an arc surface structure and forming a rib-expanding mold, protrusions installed on the inner rings of the plurality of rib-expanding plates, an adjustment unit arranged between the inner circumferences of the plurality of rib-expanding plates, a top expansion unit arranged above the adjustment unit, a top plate arranged above the top expansion unit, and a drive motor installed at the center of the top plate.

[0005] Preferably, the plurality of expansion ribs and protrusions are distributed in a circular array around the fixed base, and the bottom of the expansion ribs slides with the top of the fixed base in a limiting manner.

[0006] Preferably, the control unit includes a control screw, a self-rotating head is rotatably connected to the top of the control screw, and a locking nut is threadedly fixed to the outer circumference of the bottom end of the control screw.

[0007] Preferably, the expansion unit includes a top mold base, the top mold base is threadedly connected to a control screw, and the top end of the control screw is connected to the drive end of a drive motor.

[0008] Preferably, the top mold base descends to press the moving protrusion, and the top of the protrusion has an arc surface structure.

[0009] Preferably, the top mold base has multiple guide cavities, and the inner circumference of each guide cavity is provided with a guide rod that is fixed to the fixed base.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model allows for adjustment of the height of the self-rotating head by adjusting the threaded connection of the adjusting screw. The contact point between the self-rotating head and the top mold base is the expansion control point. By adjusting the height of the self-rotating head, the degree of expansion can be adjusted, eliminating the need to replace the expansion ribs and allowing for convenient adjustment. This solves the problem of time-consuming and troublesome replacement of the expansion rib mold.

[0012] 2. This utility model uses a modular design composed of expansion ribs and a protrusion design. It also uses a threaded fixation between the top mold base and the control screw, and a guide rod to limit the top mold base. Combined with the limited sliding of the expansion ribs and the fixed base, the operation of the screw is controlled so that the top mold base can move, pushing the expansion ribs to expand. After expanding to a certain extent, it can also drive the expansion ribs to rotate, realizing the expansion rib processing. Thus, a single motor can perform both the expansion and rotation actions, simplifying the structure and saving costs. Attached Figure Description

[0021] like Figures 1 to 5As shown, this utility model relates to an expansion rib mechanism for an automatic steel bucket production line, comprising a fixed base 1, with multiple expansion rib plates 2 arranged on the top of the fixed base 1. The multiple expansion rib plates 2 have an arc surface structure and form an expansion rib mold. Each of the multiple expansion rib plates 2 has a protrusion 3 installed on its inner ring. The multiple expansion rib plates 2 and protrusions 3 are distributed in a circular array around the fixed base 1. The bottom of the expansion rib plates 2 slides against the top of the fixed base 1, and the sliding is limited by sliding grooves and sliding blocks. The top of the multiple expansion rib plates 2 is provided with a top plate. 6. The top plate 6 is fixed to the outside for positioning. A drive motor 7 is installed at the center of the top plate 6. The drive end of the drive motor 7 is provided with an expansion unit 5. The expansion unit 5 includes a top mold base 501. Multiple guide cavities are opened on the top mold base 501. Guide rods 8, which are fixed to the fixed base 1, are provided on the inner circumference of the guide cavities. A control screw 502 is threadedly connected to the center of the top mold base 501. The top end of the control screw 502 is connected to the drive end of the drive motor 7. The top mold base 501 descends to press the protrusion 3 to move. The top of the protrusion 3 has an arc surface structure.

[0022] Working principle: The drive motor 7 is controlled by an external control structure to drive the control screw 502 to rotate. Since the top mold base 501 is limited by the guide rod 8, the top mold base 501 is lowered, pushing open the protrusion 3, causing multiple expansion rib plates 2 to expand outward. When the top mold base 501 is lowered to the position where it is blocked and limited, it can drive the fixed base 1 to rotate, so that the expansion rib plates 2 rotate synchronously, thus performing expansion rib processing on the tank body.

[0023] To facilitate convenient adjustment, an adjustment unit 4 is provided below the expansion unit 5. The adjustment unit 4 includes an adjustment screw 401, a self-rotating head 403 is rotatably connected to the top of the adjustment screw 401, and a locking nut 402 is threadedly fixed to the outer circumference of the bottom end of the adjustment screw 401.

[0024] Working principle: When adjustment is required, tighten the locking nut 402 and use a tool to rotate the adjusting screw 401 to move the self-rotating head 403 up and down. This allows adjustment of the height of the self-rotating head 403, thereby adjusting the position where the top mold base 501 is blocked from descending. This allows adjustment of the depth at which the top mold base 501 pushes open the slope of the protrusion 3, thus completing the adjustment without the need for overall disassembly and assembly, and adapting to different tanks.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
