Description

Technical Field

[0001] The utility model belongs to the technical field of bead rolling machines, and particularly relates to a bead rolling machine. Background Art

[0002] Metal barrel-shaped containers are typically composed of three joined parts, and the bottom of such containers often requires rounded corners. Existing processing methods typically involve workers manually hammering a rounded metal sheet into a basin-shaped workpiece, which is then welded together to form the metal container. This manual rounding process is time-consuming and labor-intensive, and the resulting workpieces are highly inconsistent in both size and quality, resulting in very low production efficiency and yield rates.

[0003] To this end, a rolling machine with the announcement number "CN209502655U" includes: a frame, an upper rolling assembly and a lower rolling assembly are respectively installed on the upper and lower sides of the frame, the upper rolling assembly and the lower rolling assembly are respectively provided with a rotatable upper rolling wheel and a lower rolling wheel, and the upper rolling wheel and the lower rolling wheel extend to the right of the frame, the upper rolling wheel and the lower rolling wheel are horizontally spaced and the ends close to each other are respectively provided with arc chamfers to form an arc-shaped rolling cavity between the upper rolling wheel and the lower rolling wheel, and a driving mechanism is installed on the frame and drives the upper rolling wheel or the lower rolling wheel to rotate.

[0004] However, for the above-mentioned rolling machine, although the lower end of the longitudinal screw pulls the upper rolling assembly to prevent it from falling, and the longitudinal screw can also rotate relative to the upper rolling assembly, rotating the longitudinal screw can make the longitudinal screw move up and down relative to the frame, thereby realizing the up and down movement of the upper rolling wheel, there are still the following more obvious defects during use: although the upper rolling assembly in the above-mentioned equipment can perform beading operations on metal sheets, since the other end of the metal sheet is suspended in the process of beading, it is impossible to ensure that the metal sheet is in a horizontal state during beading, which can easily cause the metal sheet to tilt and shake, resulting in the deviation of the beading route.

The embossing guide roller is installed on the mounting block through a cylindrical rod provided on one side of the guide roller frame, thereby playing the role of circumferential guidance of the metal plate during the embossing process.

[0012] Preferably, an upper beading roller is installed to the left of the center position of the upper beading shaft, and the lower end of the upper beading roller is vertically staggered on one side of the lower beading roller to achieve beading processing of the metal cylindrical part.

The driven sprocket is connected to a driving chain, and one end of the driving chain is connected to the driving sprocket to drive the lower driving shaft of the bead rolling machine to rotate, thereby realizing the rolling and beading treatment of the metal sheet by the rotation of the lower driving shaft of the bead rolling machine.

[0015] Compared with the existing technology, the technical effects and advantages of the utility model are as follows: the bead rolling machine, through the installation of side plates, and the combination of the adjustment slide groove, the limit pressure plate, the threaded rotating rod and the upper bead rolling shaft, and the bearing slide seat installed on the side plate and the lower active shaft of the bead rolling, passes the metal plate between the lower bead rolling roller and the upper bead rolling roller for bead rolling, which can support and limit the output of the plate being conveyed by the lower active shaft of the bead rolling roller and the upper bead rolling shaft. At the same time, the threaded rotating rod and the bearing slide seat can be used to make the two ends of the upper bead rolling shaft slide in the adjusting slide groove to achieve the adjustment of the vertical distance with the lower active shaft of the bead rolling, so that it can not only position and guide the plate to be rolled to maintain the effect of stable bead rolling, but also can adjust the vertical distance between the upper bead rolling roller and the lower bead rolling roller according to the thickness of the metal plate, thereby ensuring that the metal plate maintains stability in the bead rolling and will not tilt or shake, resulting in the problem of deviation of the bead rolling route.

[0016] By installing the beading guide rollers that are inclined on the front and rear ends of the inner side surfaces of the side panels and the heavy-duty casters that are arranged on the front and rear sides of the upper end of the machine in conjunction with the beading guide rollers, the heavy-duty casters are used during the beading process of the metal sheets using the lower beading roller and the upper beading roller. The metal sheets entering and exiting the beading are guided in an arc, and the beading guide rollers are used to provide circumferential guiding support for the metal sheets rolled into a cylindrical shape, thereby avoiding deformation of the metal sheets due to their own weight during the cylindrical beading, and ensuring that the metal sheets are effectively guided and supported.
