Embodiment Construction

[0020] Figure 1 to Figure 4 The centrifugal impeller shown includes a front disc 12, a blade 13, and a rear disc 11. The front disc 12 and the rear disc 11 are two disc-shaped bodies located on the upper and lower sides of the blade 13, which constitute the installation base of the blade 13, and the blade 13 is located in the front Between the disc 12 and the rear disc 11, the front disc 12, the blades 13, and the rear disc 11 are integrally formed.

[0021] It should be noted that the so-called up, down, height, horizontal, vertical and other words related to orientation in the present invention are described based on the direction shown in the drawings as a standard, and do not mean the actual assembly or running direction. , and it should be understood as a general direction, and should not be limited to the absolute value in the geometric sense, because a little error in assembly absolutely exists and should be allowed.

[0022] It can be seen that the front disk 12 is h...

Abstract

The invention provides a high-adaptability die for manufacturing a centrifugal impeller. According to the provided technical scheme, the die comprises a movable die body and a fixed die body. The fixed die body comprises a die core unit, and the die core unit has the longitudinal height variable. According to the technical scheme, the die has the beneficial effects that due to the fact that the die core unit has the longitudinal height variable, it means that the die core unit has a longitudinal extending or longitudinal compressing special effect in the space, a series of above technology problems caused by the unchangeable longitudinal height can be solved, especially, the die advancing step or the die retreating step can become so easy, and the technology problem that due to the change of the longitudinal height of some parts of the centrifugal impeller, manual manufacturing has to be selected can be solved; machining is more convenient, the production efficiency is higher, the die is particularly suitable for batched producing and machining, and the integrally-formed centrifugal impeller is easy to machine; and the strength of the centrifugal impeller at the time is completely decided by the material strength, and the breaking hidden danger caused by insufficient strength of connecting parts is avoided.

Description

technical field [0001] The invention relates to molds for manufacturing centrifugal impellers. Background technique [0002] Centrifugal impeller refers to a wind wheel that takes air in axially and leaves air radially, and uses centrifugal force (depending on the speed and outer diameter) to do work to increase the pressure of the air. The traditional molds for manufacturing centrifugal impellers can only advance and retreat horizontally. When manufacturing centrifugal impellers with longitudinal height changes, they will have to be independently manufactured for specific parts through multiple molds, and then the aforementioned steps will be repeated through manual work. The obtained parts are welded into a whole. Time-consuming and labor-intensive, low production efficiency, not suitable for mass production, and the strength of the connection structure welded at multiple parts is low, which cannot meet the performance requirements of some usage occasions.
