Impeller roller press

Abstract

The invention provides an impeller roller press. The impeller roller press is used for machining an impeller. Blades extend out of the upper surface and the lower surface of an impeller outer ring. The impeller roller press comprises a rack, a die, a motor, a pressing mechanism, an upper spinning and pressing mechanism and a lower spinning and pressing mechanism, wherein the die is matched with an impeller. The motor is arranged on the rack and is connected with the die. The pressing mechanism is arranged on the rack and can move up and down. The pressing mechanism and the die correspond to each other up and down and are located on the same central axis. The upper spinning and pressing mechanism and the lower spinning and pressing mechanism are arranged on the rack. The height of the upper spinning and pressing mechanism and the height of the lower spinning and pressing mechanism can be independently adjusted. The upper spinning and pressing mechanism and the lower spinning and pressing mechanism correspond to the upper and lower ends of the blades. According to the impeller roller press, the height of the upper spinning and pressing mechanism and the height of the lower spinning and pressing mechanism can be independently adjusted considering impellers with different heights; and after the upper spinning and pressing mechanism and the lower spinning and pressing mechanism are used to press the upper and lower ends of the blades, the die is driven by the motor to rotate to realize automatic bending of blade paws of the centrifugal impeller, so that the working efficiency and the product quality are greatly improved.

Description

technical field [0001] The invention relates to the technical field of rolling, in particular to an impeller rolling machine. Background technique [0002] The centrifugal impeller consists of a lower ring, an upper ring and a certain number of blades. There are flower retaining holes on the lower ring and the upper ring respectively. The blades pass through the flower retaining holes on the lower ring and the upper ring. on the ring. [0003] The processing technology of the centrifugal impeller mainly includes the process of inserting the blade and the process of bending the claw of the blade. If manual processing is used, not only the processing efficiency is low, but also the processing quality of the centrifugal impeller is poor. [0004] There are also some rolling devices on the market, such as a rolling device for a centrifugal impeller with Chinese patent application number 201721445944.5, "including a workbench, a positioning die, a pressing mechanism and a rolli...

AI Technical Summary

Problems solved by technology

[0005] However, the disadvantages of the above application are that the upper and lower rollers move synchronously relative to each other under the drive of the clamping mechanism, and the driving mechanism is fixed on the bottom plate and cannot be adjusted in height, and only one specific impeller can be processed.

When it is necessary to process impellers with different heights, since the mold and the driving mechanism cannot be adjusted in height, when one of the upper roller or the lower roller touches the blade, the other roller does not touch the blade, and the rolling operation cannot be realized
