Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting, and particularly relates to a multi-angle adjustable vanadium-nitrogen alloy diagonal cutting machine. Background Art

[0002] Vanadium-nitrogen alloy is a new type of alloy additive, mainly used in the production of microalloyed steel. It can significantly improve the comprehensive mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance, and at the same time endow the steel with good weldability. When reaching the same strength, adding vanadium nitride can save 30%-40% of the vanadium addition amount, thereby reducing costs. In addition, vanadium-nitrogen alloy can also be used in structural steel, tool steel, pipeline steel, steel bars and cast iron, and has broad application prospects.

[0003] In the production and processing of vanadium-nitrogen alloy, cutting is an indispensable link. Traditional cutting machines can generally only perform vertical cutting and cannot meet the need for diagonal cutting of vanadium-nitrogen alloy. For existing diagonal cutting machines, their cutting angles are often fixed and non-adjustable, which limits their application scope. Therefore, it is particularly important to develop a multi-angle adjustable vanadium-nitrogen alloy diagonal cutting machine to meet the cutting requirements at different angles.

At the same time, the support arm can also rotate in a swinging manner, so that the cutting module is tilted and diagonal cutting can be performed. The clamping and limiting mechanism and the loading and unloading mechanism of the present invention can perform synchronous linkage work through the connection of the linkage component. When the loading and unloading mechanism operates, the clamping and fixing mechanism is loosened. When the clamping and fixing mechanism performs fixed limiting, the loading and unloading mechanism is separated from the workpiece. The actions of the two mechanisms only require one power support.

[0036] Working principle: When the present invention is in use, first place the workpiece 3 on the bed body 1 and close it against the limit plate 2.

The stepping motor III 24 is started to drive the roller 25 to rotate. The roller 25 drives the workpiece 3 to move to the cutting position. Then, the air cylinder 17 drives the connecting frame 16 to slide inwards.

The stepping motor II 12 is started to drive the worm II 11 to rotate, thereby driving the support arm 9 to swing through the arc-shaped worm gear rack II 10, so that the cutting module 15 is tilted; the angle adjustment in the horizontal direction and the tilting can be adjusted simultaneously or individually. In this way, various bevel cutting operations can be performed on the workpiece 3.
