Special spinning machine for numerical control die-free fan

Abstract

The invention discloses a special spinning machine for a numerical control die-free fan. The spinning machine is provided with a spinning wheel and a support wheel which are connected by four brackets. Spin forming can be finished on various fan parts with the wall thickness of more than 12 millimeters or the diameter of more than 2,000 millimeters in the absence of a die by adopting hydraulic servo technology and numerical control technology and accurately controlling movement of the spinning wheel and the support wheel. The spinning machine has the properties of high product precision and good quality, improves the production efficiency and product quality of the fan parts, saves the production cost and does not need to use the die in the production process.

Description

technical field [0001] The invention relates to a numerically controlled spinning machine, in particular to a numerically controlled moldless fan special spinning machine. Background technique [0002] The spinning machines currently used for the production of fan parts can only be used for spinning fan parts with a wall thickness of less than 12 mm and a diameter of less than 2000 mm without a mold, and for fans with a wall thickness of more than 12 mm or a diameter of more than 2000 mm Parts cannot be completed by spinning; while using CNC molded spinning machine, although it can complete spinning for some fan parts with a wall thickness greater than 12 mm or a diameter greater than 2000 mm, it means that each fan part All rely on making a fixed mold based on its shape. When the product needs to be changed, the mold must be remade accordingly. The fan production often needs to change the shape according to the needs of customers, and the demand for each is not very large. ...

[0002] The spinning machines currently used for the production of fan parts can only be used for spinning fan parts with a wall thickness of less than 12 mm and a diameter of less than 2000 mm without a mold, and for fans with a wall thickness of more than 12 mm or a diameter of more than 2000 mm Parts cannot be completed by spinning; while using CNC molded spinning machine, although it can complete spinning for some fan parts with a wall thickness greater than 12 mm or a diameter greater than 2000 mm, it means that each fan part All rely on making a fixed mold based on its shape. When the product needs to be changed, the mold must be remade accordingly. The fan production often needs to change the shape according to the needs of customers, and the demand for each is not very large. In addition, each fan needs its own independent mold. In addition, the installation and debugging of each replacement mold is complicated. This will take time and effort, resulting in a long production cycle and high cost, and the spinning of special-shaped fan parts that cannot produce corresponding molds cannot be done. Complete; in addition, there is another manual screw-type spinning machine with molds. Although it can also complete spinning for some fan parts with a wall thickness greater than 12 mm or a diameter greater than 2000 mm, the fan parts are produced under manual conditions. low precision, poor quality
