Description

Welding and cutting device

The invention relates to a workpiece processing device, in particular to a welding and cutting device.

Referring to FIG. 1, a conventional plasma welding apparatus 1 includes a gun body 11 defining an installation space 110, a gas supply pipe 12 disposed in the installation space 110, and an installation space 110. An electrode 13 connected to the front end of the gas supply pipe 12 and a set of welding heads 14 connected to the electrode 13 and extending outside the installation space 110. The gas supplied by the gas supply pipe 12 will form a plasma due to the high electrical energy applied by the electrode 13, and the plasma will cause the welding head 14 to generate high heat. Since the welding head 14 is made of a high melting point material such as tungsten, it can be maintained at a temperature of thousands of degrees without melting, so that other high melting point materials can be melted by its high temperature to perform welding processing operations.

However, although the welding point 14 has a high melting point, not all of the surrounding components can withstand high temperatures. Therefore, after the temperature of the welding head 14 reaches a certain level, the need for heat dissipation must be considered, otherwise the plasma welding device 1 Components are quite susceptible to high temperatures Damage, which affects service life. Among them, since the welding head 14 is a solid cone-shaped metal block, it is difficult to quickly and effectively dissipate heat, and the gas supplied through the gas supply pipe 12 is also difficult to effectively produce an air cooling effect. Therefore, the temperature of the welding head 14 is too high. When it is high and difficult to disperse, it is necessary to stop the work and wait for heat radiation, which also affects the work efficiency of performing welding using the plasma welding apparatus 1.

Referring to FIG. 2, a copper base 2 of an existing plasma cutting device includes a main body portion 21 defining a front end space 210, a solid portion 22 solidly installed in the front end space 210, and an embedded part in the The solid portion 22 is also suitable for the electrode portion 23 that supplies plasma-forming electrical energy toward the workpiece. The plasma cutting device can form a plasma to cut a workpiece by transmitting electric energy from the electrode portion 23. However, since the solid portion 22 is also solid, it is difficult to effectively dissipate heat, which may also affect the efficiency of the cutting operation.

Therefore, an object of the present invention is to provide a welding and cutting device that is favorable for heat dissipation and prolongs the service life.

Therefore, the welding and cutting device of the present invention includes a gun body defining an installation space, a gas supply pipe installed in the installation space and used to provide a gas as an electric energy medium, and a gas supply pipe connected to the gas supply pipe and used for An electrode module provided by the gas supply pipe with electrical energy and an electrode module installed on the gun body and disposed at the front end of the electrode module, and surrounding a process defining an accommodation area for the electrode module to be accommodated For the head.

The gas supplied by the gas supply pipe can enter the accommodating area while generating a heat dissipation effect.

The effect of the present invention is that the working head is in the shape of a cover surrounding the accommodation area, which is more conducive to direct heat dissipation than solid, and the gas supplied by the gas supply pipe can enter the accommodation. The heat radiation effect is generated on the working head, so it is beneficial to dissipate heat after performing welding and cutting, avoiding damage to surrounding components at high temperature, and prolonging the service life of the welding and cutting device.

Other features and effects of the present invention will be clearly presented in the embodiment with reference to the drawings, in which: FIG. 1 is a cross-sectional view illustrating a conventional plasma welding device; FIG. 2 is a cross-sectional view illustrating a conventional electrical welding device. Copper seat of the slurry cutting device; FIG. 3 is a cross-sectional view illustrating an embodiment of the welding and cutting device of the present invention; and FIG. 4 is a schematic view similar to FIG. 3, illustrating the heat dissipation effect of this embodiment.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.

Referring to FIG. 3, an embodiment of the welding and cutting device of the present invention includes a gun body 3 defining an installation space 300, a gas supply pipe 4 installed in the installation space 300 and used to provide a gas as an electric energy medium, An electrode module 5 connected to the gas supply pipe 4 and used to provide electrical energy to the gas supplied by the gas supply pipe 4, and an electrode module 5 installed on the gun body 3 and disposed at the front end of the electrode module 5 and surrounding the boundary A working head 6 is received in a receiving area 600 for receiving the electrode module 5.

The working head 6 includes a surrounding wall 61 surrounding the electrode module 5 and a tapered portion 62 extending from the surrounding wall 61 and having a tapered shape. That is, the whole of the working head 6 is a non-solid cone-shaped cover, because the solid part is thinner than the solid design of the prior art, and because the contact area is large, it is beneficial to directly dissipate heat.

Referring to FIG. 4, the gas supplied by the gas supply pipe 4 can be excited by the high electric energy provided by the electrode module 5, and thus generates a high-energy arc and plasma, in addition to being generated by the electric energy provided by the electrode module 5. Part of the arc and plasma can enter the accommodating area 600 while generating air-cooled heat dissipation effect on the work head 6 to avoid excessive heat accumulation in the work head 6, thereby protecting the surrounding components that are less resistant to high temperatures .

In summary, the welding and cutting device of the present invention can present a cover-like design through the working head 6 and cooperate with the gas supply pipe 4 to inject gas into the accommodating area 600, and simultaneously improve the rate of direct heat removal and gas The cold heat dissipation mechanism optimizes the heat dissipation of the working head 6, effectively protects the surrounding high temperature resistant components, and thereby prolongs the service life of the invention, so it can indeed achieve the purpose of cost invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
