Problems solved by technology

[0006]The cutting machine needs to design a manual operation interface, such as panel buttons or switches, so that the cutting machine can be operated manually to switch between the built-in air supply mode and the external air supply mode. The panel area, number of parts, and volume of the cutting machine all have a certain impact, which increases the material cost of the cutting machine
[0007]2. Low intelligence and complex operation
[0010]When the external and internal air supply modes are switched, not only the air path connection between the air pump and the air inlet needs to be changed, but also the mode switch needs to be manually operated on the panel. The start and stop of the air pump is controlled by manual operation, and there is a certain delay time, which increases the extra working time of the air pump and reduces the life of the air pump

Embodiment 3

[0077] This embodiment illustrates the cycle process of switching the cutting machine from the external air supply to the internal air supply, and then from the internal air supply to the external air supply, and further explains the technical solution of the present invention.

[0078] see figure 2 with image 3 , when the cutting machine is turned on, the behavior is that the user connects the external air pump to the air inlet 7, that is, the user selects the external air supply mode, and the processor 1 initializes, and the default is the internal air pump 6 The working state is non-working, when the air inlet pressure value is greater than the preset threshold of 0.2MPa, the processor 1 judges that the current user selects the external air supply mode, and the processor 1 closes the solenoid valve 3 , the user can re-open the solenoid valve 3 by cutting the gun 8 together.

[0079] When the user switches from the external air supply mode to the built-in air supply mode...

Abstract

The invention discloses a control system and method for automatically identifying internal and external gas pumps. According to the control system and method for automatically identifying the internal and external gas pumps, the pressure value of a gas inlet is detected through a pressure sensor, the gas supply mode of a cutting machine is judged through a processor according to the pressure value and the working state of the internal gas pump, an electromagnetic valve and an internal gas pump control circuit are controlled according to the gas supply mode, the internal gas pump is controlled to be opened and closed through the internal gas pump control circuit, and whether gas is conveyed to a cutting gun or not is controlled through the internal gas pump and the electromagnetic valve. A panel of the cutting machine is simpler, the material consumption of the machine is reduced, and the cutting machine is more convenient to operate; automatic circulation switching between an internal gas supply mode and an external gas supply mode can be achieved, and the intelligent level of the cutting machine is improved; and the processor automatically identifies the gas supply mode requirement to control start and stop of the internal gas pump, so that the extra working time of the internal gas pump is shortened, the service life of the internal gas pump is prolonged, and high application value is achieved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a control system and method for automatically identifying internal and external air pumps. Background technique [0002] With the development of the modern mechanical processing industry, on the one hand, the demand for cutting machines is getting bigger and bigger; on the other hand, the requirements for cutting quality and precision are getting higher and higher. The demand for machines with advanced automatic cutting functions is also increasing, which puts forward higher requirements for the functions of cutting machines. [0003] The cutting machine melts the metal quickly by establishing a plasma arc at high temperature, uses the air pump of the cutting machine to compress the air, and sends the compressed air to the air inlet of the cutting machine, and then sends it to the cutting torch of the cutting machine from the air inlet, and uses the compressed air to Blow aw...
