Embodiment 1

[0056] In order to realize the above process, this embodiment shows a solid-phase friction extrusion spindle system, which is a key mechanism system for realizing the principle of the solid-phase friction extrusion additive manufacturing process. like image 3 and Figure 4 As shown in (a), a solid-phase friction extrusion additive manufacturing spindle system includes a spindle outer casing 10 and a first fixing flange 11 fixed at the bottom of the spindle outer casing 10, which is coaxial from the outside to the inside. The sleeve is provided with a main shaft hollow rotating shaft 12 and a feeding rotating shaft 701; such as Figure 5 As shown in (a) and 5(b), the feeding rotating shaft 701 is provided with a first single eccentric channel 18 for placing the round bar consumables 1701, and both ends of the feeding rotating shaft 701 protrude from the main shaft housing two ends of the body 10; the outer periphery of the feeding rotating shaft 701 is provided with a feedin...

Embodiment 2

[0072] like image 3 and Figure 4 As shown in (b), Embodiment 2 shows a solid-phase friction extrusion spindle system with double eccentric channels, and the content similar to Embodiment 1 will not be repeated, and only the differences will be described below. The spindle system includes a feeding rotating shaft 702; such as Figure 5As shown in (c) and 5(d), the feeding rotating shaft 702 is provided with a first double eccentric channel 19 for placing the round bar consumables 1702 . A mounting base 1302 is rigidly connected to the bottom of the hollow rotating shaft 12 of the main shaft, and a double eccentric channel friction pressing shoulder 1402 is rigidly connected to the bottom of the mounting base 1302 .

[0073] The feeding rotating shaft 702 determines the amount of material to be charged for the round bar consumables 1702 and the appearance size of the overall spindle system. The length of the feeding rotating shaft 702 is 600mm and the diameter is 40mm. The d...

Abstract

The invention discloses a solid-phase friction extrusion additive manufacturing spindle system, which comprises a spindle outer casing and a first fixing flange fixed at the bottom of the spindle casing. a shaft and a feeding rotating shaft; the bottom of the hollow rotating shaft of the main shaft is rigidly connected with a coaxially arranged mounting base, and the bottom of the mounting base is rigidly connected with a friction extrusion shoulder with an eccentric channel; the feeding rotating shaft is provided with There is a first eccentric channel for placing round bar consumables; the feeding rotating shaft and the main hollow rotating shaft form a double-layer independent rotating shaft structure. The spindle system of the present invention adopts two friction extrusion principles to realize the friction extrusion additive manufacturing process of single or two round bar consumables filling materials, the utilization rate of round bar consumables is higher, the bonding strength and width of friction extrusion interface At the same time, it can realize the intermittent or continuous feeding process of round bar consumables, which provides an important basis for the development of industrialized solid-phase friction extrusion additive manufacturing equipment.

Description

technical field [0001] The invention belongs to the technical field of solid phase friction welding and additive manufacturing, and in particular relates to a spindle system for solid phase friction extrusion additive manufacturing, which is used to realize the friction extrusion additive manufacturing process of various metal bars. Background technique [0002] At present, the metal additive manufacturing process of laser, electron beam and electric arc using fusion welding process has been greatly developed. For example, parts made by laser and electron beam additive manufacturing such as titanium alloy and nickel-based alloy have been widely used in aerospace structure manufacturing. application. However, there are still many challenges in the manufacture of high-performance and high-load-bearing additive components. Due to the metallurgical phenomenon of metal melting and solidification caused by the fusion welding process, the components manufactured by metal powder add...
