Description

Technical Field

[0001] The utility model relates to the technical field of plasma cutting, in particular to a plasma cutting nozzle which is easy to install and fix. Background Art

[0002] Plasma arc cutting is a processing method that uses the heat of a high-temperature plasma arc to locally melt and evaporate the metal at the workpiece incision, and uses the momentum of high-speed plasma to remove the molten metal to form an incision. Plasma cutting with different working gases can cut various metals that are difficult to cut with oxygen cutting, especially for non-ferrous metals: stainless steel, aluminum, copper, titanium, and nickel. The cutting effect is better; its main advantage is that when cutting metals of small thickness, the plasma cutting speed is fast, especially when cutting ordinary carbon steel thin plates, the speed can reach 5 to 6 times that of the oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, and there is less heat-affected zone. In plasma cutting, the nozzle is often the main consumable and plays a key role.

[0003] However, the existing plasma cutting nozzle needs to be tightened with the help of tools such as wrenches during installation. It is inconvenient to install when there are no tightening tools nearby, resulting in long maintenance time and affecting production speed. In addition, when the cutting nozzle is disassembled, the cutting nozzle still retains a high temperature, and the worker's hands may be burned when directly contacting the cutting nozzle, which poses a hidden danger to the worker's personal safety. Therefore, a plasma cutting nozzle that is easy to install and fix is ​​proposed. Utility Model Content

One end of the spring 8 is fixedly connected to the gun head 1. The setting of the spring 8 makes it convenient for the cutting nozzle 2 to slide to the end. The limit seat 9 can quickly and automatically limit and fix the cutting nozzle 2. A guide component is arranged inside the limit seat 9. The guide component includes a limit rod 11 slidably arranged inside the limit seat 9, and the bottom of the limit rod 11 is fixedly connected to the gun head 1, and a limit plate 12 is fixedly arranged on the top of the limit rod 11. The number of the limit rod 11 and the limit plate 12 is two, and the two limit rods 11 and the two limit plates 12 are symmetrically distributed, which limits the sliding trajectory of the limit seat 9 and prevents the limit The seat 9 tilts when sliding, causing accelerated wear, which increases the service life of the limit seat 9. The limit groove 5 is provided with a pull buckle 10 through a clamping assembly. A limit hole 13 is set through the surface of the pull buckle 10. The pull buckle 10 is provided with a limit assembly through the limit hole 13. The limit assembly includes a limit pin 14 slidably set inside the limit hole 13. A fixing plate 15 is fixedly set on the top of the limit pin 14. A fixing sleeve 16 is overlapped inside the fixing plate 15, and the fixing sleeve 16 is fixedly connected to the gun head 1. The fixing sleeve 16 is overlapped with the limit pin 14. A spring 2 7 is overlapped inside the fixing sleeve 16, and the spring 2 7 is overlapped with the limit pin 14. The clamping assembly is matched with the limit assembly. The locking is performed to prevent the spring 8 from becoming unstable and causing the cutting nozzle 2 to fall off. The plasma cutting nozzle that is easy to install and fix can be installed by simply pulling the fixing plate 15 to the right to disengage the limiting pin 14 from the limiting hole 13, and then the cutting nozzle 2 is inserted into the gun head 1 to automatically limit and fix the cutting nozzle 2 through the clamping assembly, so that the staff can install and fix the cutting nozzle 2 without using tools, making it faster and more convenient for the staff to replace the cutting nozzle 2, preventing the lack of fastening tools from causing long maintenance time and affecting the production speed, and avoiding the staff's hands from directly contacting the cutting nozzle 2 and causing burns when disassembling the cutting nozzle 2.

[0022] The plasma cutting nozzle, which is easy to install and fix, is connected to a 220V mains power supply, and the main controller can be a conventional known device for controlling a computer or the like.

[0023] When in use: during installation, pull the fixing plate 15 to the right, so that the fixing plate 15 pulls the limiting pin 14 to slide to the right and disengage from the limiting hole 13, then make the limiting rib 3 on the cutting nozzle 2 face downward and push the cutting nozzle 2 so that the cutting nozzle 2 and the limiting rib 3 slide into the inside of the gun head 1, and when sliding, the bevel 2 6 contacts the bevel 1 4, and the bevel 2 6 pushes the bevel 1 4 to make the limiting seat 9 slide upward, and when the cutting nozzle 2 slides to the end, the limiting seat 9 slides into the limiting position by the pulling force of the spring 1 8 When the cutting nozzle 2 needs to be disassembled, it is only necessary to pull the fixing plate 15 to the right first, so that the fixing plate 15 pulls the limiting pin 14 out of the limiting hole 13, and then pull the buckle 10 upward so that the buckle 10 pulls the limiting seat 9 to slide upward and out of the limiting groove 5, and then point the cutting nozzle 2 toward the ground, and the cutting nozzle 2 can automatically detach from the gun head 1 by its own gravity.
