Description

An automatic plasma cutting machine with an optimized corexy structure

technical field

The utility model relates to a plasma cutting machine, in particular to an automatic plasma cutting machine adopting an optimized corexy structure.

Background technique

Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to partially or partially melt (and evaporate) the metal at the incision of the workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form a cut. Plasma cutting machines are widely used in automobiles, Locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structures and other industries. Although the plasma cutting machine has higher cutting precision than the traditional cutting machine, there are still a small amount of burrs when cutting, and it is difficult to achieve the proper processing accuracy for fine objects. Moreover, the existing plasma cutting technology is controlled by traditional mechanical programs. complex.

The corexy structure is widely used in printers, and its main feature is that two stepper motors are used to cooperate to complete the movement in the XY direction, which not only has high precision but also fast movement speed. The corexy structure is rarely used in other fields. If the corexy motion mode is combined with plasma cutting technology, the cutting accuracy can be greatly improved and the generation of burrs can be reduced.

Utility model content

The purpose of the invention of the utility model is to provide an automatic plasma cutting machine with an optimized corexy structure for the existing plasma cutting technology in the prior art using traditional mechanical program control, complicated operation and low precision. The machine is not only easy to operate, but also can greatly improve the cutting accuracy and reduce the generation of burrs.

In order to achieve the above object, the technical solution adopted by the utility model is:

Of course, what is more complicated is that when the speeds of the two stepping motors are the same, but their speeds change with time, the belt drives the X-axis slider to move along the X-axis slide rail, and the belt drives the Y-axis slide The block moves along the Y-axis slide rail. Since the movement speed of the X-axis slide block and the Y-axis slide block changes with time, it can drive the torch to complete the curve motion.

Since the movement of the X-axis slider and the Y-axis slider are jointly controlled by two stepping motors, the cutting precision and cutting force are higher than ordinary plasma cutting machines, so it can reduce the The generation of burrs, and greatly improve the cutting accuracy.

This device not only introduces the corexy concept into the plasma cutting machine, but also optimizes the traditional corexy structure, removes the redundant two driven wheels, and uses a single belt to drive the X-axis slider and the Y-axis slider The movement greatly reduces the length of the belt and improves the cutting efficiency.
