Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing, in particular to a tool for preventing deformation of thin-walled cylinders from being rolled into round shapes. Background Art
[0002] Many chemical equipment use catalysts to increase the rate of chemical reactions. To ensure that the catalyst is lost through the discharge port after promoting the chemical reaction of the medium, the catalyst is generally placed in a screen drum to ensure that the catalyst is always retained in the screen drum after the medium undergoes a chemical reaction. However, since the screen drum is covered with linear sieve holes, its longitudinal stiffness is only 1 / 2500 of the original and is very soft. The length of the screen drum is more than 22 meters, so the screen drum is easily deformed during rounding, affecting the processing efficiency of the screen drum. Utility Model Content
[0003] The utility model aims to solve the shortcomings in the prior art and proposes a thin-walled cylinder rounding anti-deformation tool.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A thin-walled cylinder rounding anti-deformation tooling is designed, which includes a frame and a hanger, a threaded rod is rotatably installed in the middle of the frame, a threaded sleeve is symmetrically threaded on the outer side of the threaded rod, a roller bracket is fixedly installed on the top of the threaded sleeve, a guide rod is fixedly installed in the middle of the frame, the guide rod passes through the threaded sleeve, a three-roller plate rolling machine is fixedly installed in the middle of the frame, the hanger passes through the screen drum, and is located directly above the three-roller plate rolling machine.
[0006] Preferably, the hanger includes a cross bar, which passes through the screen cylinder, and both ends of the cross bar are fixedly installed with hanging plates, one side of the hanging plate is fixedly installed with a spring, and the spring is located in the cross bar, one side of the cross bar is opened with a sliding hole, one end of the spring is fixedly installed with a limit block located inside the cross bar, and one side of the limit block passes through the sliding hole.
[0007] Preferably, a slope is provided on one side of the limit block.
[0008] The thin-walled cylinder rounding anti-deformation tooling proposed in the utility model has the following beneficial effects:
[0009] The three-roller plate rolling machine provided in the utility model can roll the screen drum into a round shape, and the roller bracket and the frame can support the screen drum, effectively preventing the screen drum from collapsing and deforming during the rolling process. The spring in the hanger pushes the limit block to move, and the limit block limits the screen drum, which can ensure that the screen drum is located in the middle of the cross bar, so that the forces acting on the screen drum are the same, preventing the screen drum from being deformed due to uneven force, thereby effectively improving the processing efficiency of the screen drum.
