Description

Technical Field

[0001] The present invention relates to the technical field of diameter-changing rod processing, and more particularly to a spinning device for diameter-changing rod processing. Background Art

[0002] A reducer refers to a rod with different diameters at different parts of the rod body. It is usually used to connect components of different sizes or to adapt to specific space and functional requirements. For example, a segmented reducer is made by welding several cylindrical tubes of different diameters through an arc transition, such as a segmented reducer flagpole. It is relatively simple to make and easy to transport. A tapered reducer: the rod body adopts a one-time molding technology, without welding points. The entire flagpole tapers upward, is upright and spectacular, and can increase the strength and stability of the rod body, such as a tapered one-piece molded flagpole. When producing reducers, spinning equipment is required for processing.

[0003] According to the search, the patent number CN208712624U discloses a double-blade mechanism for a CNC spinning machine, including a spindle device, a tail top device and a spinning wheel. The tail top device is arranged at the front end of the spindle device. There are two spinning wheels, which are respectively arranged on the left and right sides of the front end of the spindle device, and there is a certain angle between the spinning wheel and the spindle device. The spinning wheel is detachably arranged on the tool rod, and a workbench is arranged below the tool rod. The tool rod is connected to the workbench. A position adjustment device is arranged below the workbench, and the workbench is connected to the position adjustment device. The double-blade mechanism of the CNC spinning machine has two spinning wheels with adjustable positions at the front end of the spindle device, and the spinning wheels can be removed from the tool rod, avoiding the failure rate of multiple tool holders designed on one side. When working, two spinning wheels can be selected to work simultaneously, with high work efficiency and high precision.

[0004] Regarding the relevant technologies mentioned above, the current spinning equipment in the existing technology is usually in the above-mentioned state. When working, two pressure wheels are used to realize the processing of the variable diameter rod. However, in the actual operation process, in order to make the pressure wheel fit well with the surface of the variable diameter rod during the spinning process and ensure uniform pressure distribution and precise forming, it is necessary to select a pressure wheel of appropriate size according to the diameter size of each section of the variable diameter rod. When processing the variable diameter rod through the spinning device, it is also necessary to replace pressure wheels of different materials. This mainly depends on factors such as the material of the variable diameter rod, processing technology requirements and production efficiency. For example, when processing metal materials with high hardness and strength such as titanium alloy and high-strength alloy steel, it is necessary to use a pressure wheel made of cemented carbide or ceramic. For soft metal materials such as aluminum and copper, pressure wheels made of elastic materials such as nylon and polyurethane can be selected. Therefore, the pressure wheel needs to be replaced. The pressure wheel in the existing technology is not easy to replace. Different pressure wheel requirements require the replacement of different equipment, which results in poor functionality of the device and affects the use of the equipment. Summary of the Invention
