背景技术Background technique
电焊机的原理是利用正负两极在瞬间短路时产生的高温电弧来熔化电焊条上的焊料和被焊材料，使被接触物相结合的目的。电焊机相当于一个大功率的变压器，将220/380V交流电变为低电压、大电流的电源，输出直流电或交流电。The principle of the electric welding machine is to use the high-temperature arc generated when the positive and negative poles are short-circuited instantaneously to melt the solder on the electrode and the material to be welded, so as to combine the objects to be contacted. The electric welding machine is equivalent to a high-power transformer, which turns 220/380V AC into a low-voltage, high-current power supply, and outputs DC or AC.
目前使用较多的普通电焊机主要有：交流弧焊机、直流焊机、变频焊机等等，这些电焊机的普遍输入功率在8-12千瓦左右，这就意味着在野外施工焊接时必须带上笨重的发电机组和较大的电缆电线连接设备，极不方便。而且，如果是直流焊机，其还要在交流电机的基础下加装整流元件，或者是使用直流发电机。Common electric welding machines currently used mainly include: AC arc welding machine, DC welding machine, frequency conversion welding machine, etc. The general input power of these electric welding machines is about 8-12 kilowatts, which means that welding must be performed in the field It is extremely inconvenient to carry a heavy generator set and larger cables and wires to connect equipment. Moreover, if it is a DC welding machine, it needs to install a rectifier element on the basis of the AC motor, or use a DC generator.

具体实施方式detailed description
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明技术方案作进一步非限制性的详细描述。In order to understand the above-mentioned purpose, features and advantages of the present invention more clearly, the technical solutions of the present invention will be described in further non-limiting detail below in conjunction with the accompanying drawings and specific embodiments.
见图1原理图，电焊机包括充电器模块、可充电电池组、第一限流电阻、第二限流电阻、稳压电源、第一散热风扇和第二散热风扇。Referring to the schematic diagram in Figure 1, the welding machine includes a charger module, a rechargeable battery pack, a first current limiting resistor, a second current limiting resistor, a regulated power supply, a first cooling fan and a second cooling fan.
本实施例的充电器模块为常用充电器模块，其输入端接市电或发电机，输入220V交流电，输出端接可充电电池组。本实施例的充电器模块包括三个相互并联的充电器，每个充电器相互独立控制，并且输出功率均为250W，因此本充电器模块具有三种输出模式：第一种是一个充电器接可充电电池组，那么输出功率为250瓦，输出电流为5A；第二种是两个充电器相互并联，然后接可充电电池组，那么输出功率为500瓦,输出电流为10A；第三种是三个充电器相互并联，然后接可充电电池组，那么输出功率为750瓦,输出电流为15A。The charger module of this embodiment is a commonly used charger module, its input terminal is connected to a commercial power or a generator, its input is 220V alternating current, and its output terminal is connected to a rechargeable battery pack. The charger module of this embodiment includes three chargers connected in parallel, each charger is controlled independently of each other, and the output power is 250W, so this charger module has three output modes: the first one is a charger connected to Rechargeable battery pack, then the output power is 250 watts, the output current is 5A; the second is two chargers connected in parallel, and then connected to the rechargeable battery pack, then the output power is 500 watts, the output current is 10A; the third is Three chargers are connected in parallel, and then connected to a rechargeable battery pack, then the output power is 750 watts, and the output current is 15A.
本机设置三种充电输出的目的主要是考虑输出功率更小时使用,当充电器模块处在第一种输出模式时,输出功率为250瓦,如果不是不间断地对工件进行焊接，本电焊机仍能处于正常的工作状态，同时也是为了在电力匮乏的地区保证其良好的工作状态，如岛屿、草原、高寒山区等，拥有丰富的风力资源作业时，可以用携带的风力发电机提供充电。The purpose of setting three kinds of charging output on this machine is mainly to consider the use when the output power is smaller. When the charger module is in the first output mode, the output power is 250 watts. If the workpiece is not welded continuously, the welding machine It can still be in a normal working state, and it is also to ensure its good working state in areas where power is scarce, such as islands, grasslands, alpine mountainous areas, etc. When operating with abundant wind resources, it can be charged by a portable wind generator.
实际上，在日常焊接过程中,焊工需要对工件进行清理，修补，换焊条，检查焊接质量等，所以电焊机一般处于间断式工作，本实施例的充电器模块基本满足日常工作所需。In fact, in the daily welding process, the welder needs to clean, repair, replace the welding rod, check the welding quality, etc., so the electric welding machine is generally in intermittent operation, and the charger module of this embodiment basically meets the daily work requirements.
本实施例的可充电电池组由五个同规格的蓄电池串联而成，每个蓄电池的额定电压为12V，额定容量为20A时，所以可充电电池组可输出60V稳定直流电，输出电流为120-150A。The rechargeable battery pack in this embodiment is composed of five batteries of the same specification connected in series. When the rated voltage of each battery is 12V and the rated capacity is 20A, the rechargeable battery pack can output 60V stable direct current with an output current of 120- 150A.
第一限流电阻和第二限流电阻相互并联，并且均电接可充电电池组，该两个限流电阻采用并联方式可适当增大输出电流。第一限流电阻包括相互串联的第一定额电阻和第一可调电阻，第一定额电阻的电阻值为0.2-0.3Ω，第一可调电阻的电阻值范围为0-0.5Ω。第二限流电阻与第一限流电阻规格相同，也是包括相互串联的第二定额电阻和第二可调电阻，第二定额电阻的电阻值为0.2-0.3Ω，第二可调电阻的电阻值范围为0-0.5Ω。The first current-limiting resistor and the second current-limiting resistor are connected in parallel with each other, and both are electrically connected to the rechargeable battery pack. The parallel connection of the two current-limiting resistors can appropriately increase the output current. The first current-limiting resistor includes a first rated resistor and a first adjustable resistor connected in series, the first rated resistor has a resistance value of 0.2-0.3Ω, and the first adjustable resistor has a resistance value range of 0-0.5Ω. The second current-limiting resistor has the same specifications as the first current-limiting resistor, and also includes a second rated resistor and a second adjustable resistor connected in series, the resistance value of the second rated resistor is 0.2-0.3Ω, and the resistance of the second adjustable resistor The value range is 0-0.5Ω.
稳压电源输入端与可充电电池组耦合，输出端与第一散热风扇、第二散热风扇耦合，输出端电压为24V，电流为0.25A。第一散热风扇和第二散热风扇功率规格相同，并且相互并联。该两个散热风扇的扇叶的直径为110mm。The input end of the regulated power supply is coupled to the rechargeable battery pack, the output end is coupled to the first cooling fan and the second cooling fan, the output voltage is 24V, and the current is 0.25A. The first cooling fan and the second cooling fan have the same power specification and are connected in parallel. The blades of the two cooling fans have a diameter of 110mm.
本实施例的电焊机的工作过程大致是：220V交流电经充电器模块对可充电电池组进行充电，可充电电池组的电能经限流后输出，提供电焊条所需的焊接电流。两个散热风扇对可充电电池组和两个限流电阻扇风散热，提高工作稳定性。本电焊机采用了可充电电池组储能再释放，即使断开220V供电仍能继续工作(工作时间由电池容量而定)。The working process of the electric welding machine in this embodiment is roughly: 220V alternating current charges the rechargeable battery pack through the charger module, and the electric energy of the rechargeable battery pack is output after current limiting to provide the welding current required by the welding rod. Two cooling fans cool the rechargeable battery pack and two current-limiting resistors to improve working stability. This welding machine uses a rechargeable battery pack to store energy and then release it, and it can continue to work even if the 220V power supply is disconnected (the working time is determined by the battery capacity).
当把本实施例的电焊机的限流电阻调整电阻功率加大后，充电器模块功率也加至1-2千瓦时，可充电电池组也增大容量到约100A时，完全可以对各种大型设备进行焊接。After the current-limiting resistor adjustment resistor power of the electric welding machine of the present embodiment is increased, the power of the charger module is also added to 1-2 kilowatt hours, and when the rechargeable battery pack also increases the capacity to about 100A, it can be used for various Large equipment for welding.
