Description

Technical Field

[0001] The utility model belongs to the technical field of rolling machines, in particular to a rolling machine which is convenient for changing the rolling diameter. Background Art

[0002] Rolling machine is a kind of equipment used to roll metal sheets or profiles into round or arc shapes. It is often used to manufacture flanges, pipes, tanks, etc. The most common type is the mechanical rolling machine. The motor drives the reducer, and the reducer outputs power to drive the working roller to rotate, so that the metal sheet is gradually bent and deformed under the action of the working roller, and finally rolled into a round or arc shape. However, it still has the following disadvantages in actual use:

[0003] 1. During the rolling process of the rolling machine, the plate is placed between the active roller and the driven roller of the rolling machine. The active roller rotates and the driven roller cooperates to roll the plate. However, when rolling different plates, the rolling diameter of the rolling machine needs to be adjusted. Since each roller of the rolling machine is in the process of rolling extrusion, replacing the roller sleeve is a common method for changing the rolling diameter. The installation of the roller sleeve can be directly installed by bolts or interference fit. There are many steps for direct installation and replacement by bolts. The interference fit requires heating treatment, and the operation steps are relatively cumbersome. It is not convenient to change the rolling diameter of the rolling machine.

[0004] 2. Secondly, during the rolling process of the rolling machine, in order to unload the rolled workpiece of the rolling machine, one end of the rolling machine needs to be disassembled. At this time, the end of the rotating shaft is suspended in the air. The rotating shaft is relatively long and is directly suspended in the air. The center of gravity is far away from the center of the supporting structure, causing the rotating shaft to bend after working in the air for a long time, affecting the working stability of the rotating shaft.

[0009] Furthermore, an interlocking strip is fixed on the inner wall of the roller sleeve, and the interlocking strip is movably connected in the movable groove. A pulling handle is symmetrically fixed to one end of the bonding disk away from the rotating disk. The roller sleeve restricts the rotating shaft through the interlocking strip, and the bonding disk is driven to move by the pulling handle during the pulling process.

[0010] Furthermore, a mating disk is rotatably connected to one side of the movable plate close to the roller sleeve, a movable block is fixed at the center of one end of the mating disk away from the movable plate, the movable block is movably connected in the socket, and the movable plate supports the rotating shaft through the movable block on the mating disk.
