In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.
[0024] Please refer to Figure 1 The utility model provides a gas circuit integrated device for a laser cutting machine, including an integrated gas outlet block 1, on which multiple groups of gas inlet devices are arranged, and different gas circuits are integrated on the integrated gas outlet block 1. Among them, a right-angle quick-connect plug 11 is provided on the integrated gas outlet block 1 to blow out the integrated gas, and the right-angle quick-connect plug 11 is aligned with the external laser head terminal for use.
[0025] Furthermore, two gas distribution blocks 2 are connected above the integrated gas outlet block 1, and the gas distribution blocks 2 are used to connect different gas inlet devices to introduce gas into the integrated gas outlet block 1. The gas distribution blocks 2 are respectively connected to the low-pressure gas supply component 3 and the high-pressure gas supply component 4, and the low-pressure gas supply component 3 is used to deliver low-pressure gas, such as oxygen, etc.; the high-pressure gas supply component 4 is used to deliver high-pressure gas, such as nitrogen, air, etc.
[0026] The low-pressure gas supply component 3 is separately controlled and connected to the high-pressure gas supply component so that different gases can be controlled and adjusted separately. The low-pressure gas supply component 3 includes a low-pressure proportional valve 31 and a low-pressure solenoid valve 32. The low-pressure proportional valve 31 is used to adjust the output ratio of the low-pressure gas, and the low-pressure solenoid valve 32 is used to adjust the switch of the low-pressure gas supply component 3. The high-pressure gas supply component 4 includes a high-pressure proportional valve 41 and a high-pressure solenoid valve 42. The high-pressure proportional valve 41 is used to adjust the output ratio of the high-pressure gas, and the high-pressure solenoid valve 42 is used to adjust the switch of the high-pressure gas supply component 4.
[0027] Furthermore, the low-pressure gas supply assembly 3 and the high-pressure gas supply assembly 4 are respectively provided with a low-pressure straight-through quick-plug connector 33 and a high-pressure straight-through quick-plug connector 43, through which the gas is connected to the gas circuit integrated device. The low-pressure straight-through quick-plug connector 33 is connected to an external low-pressure gas supply device, and the high-pressure straight-through quick-plug connector 43 is connected to an external high-pressure gas supply device.
[0028] By respectively arranging the low-pressure gas supply component 3 and the high-pressure gas supply component 4 on the integrated gas outlet block 1, the proportional output of high-pressure or low-pressure auxiliary gas required by the laser head is covered at the same time, and can be switched back and forth. Batches of materials of different thicknesses and different materials can be processed on the same equipment.
[0029] Please refer to Figure 2 , Figure 3 as well as Figure 4 The low-pressure gas supply component 3 and the high-pressure gas supply component 4 are arranged on the integrated gas outlet block 1 through the gas distributor block 2, and the gas distributor block 2 is fixed on the integrated gas outlet block 1. Among them, a one-way valve 21 is embedded under the gas distributor block 2, and the gas passes through the one-way valve 21 and is sent into the integrated gas outlet block 1. The one-way valve 21 can ensure that the gas can only flow in one direction to prevent backflow, especially to prevent low-pressure gas from entering the high-pressure channel on the other side, or to prevent high-pressure gas from entering the low-pressure channel. At the same time, the one-way valve 21 can help control the pressure in the gas system to ensure that a stable pressure level can be maintained when the gas flows in the system.
[0030] In addition, rubber pads are provided at both the upper and lower ends of the one-way valve 21, which can fill the tiny gap at the connection and press the one-way valve 21 between the gas distribution block 2 and the integrated gas outlet block 1 to improve the sealing performance.
[0031] A rotary joint 6 is provided above the gas distributor block 2, and a thread is provided at the lower end of the rotary joint 6, which is screwed into the gas distributor block 2 through thread connection with the gas distributor block 2. An O-ring 61 is provided on the upper end surface of the thread of the rotary joint 6, which can improve the sealing performance of the connection between the rotary joint 6 and the gas distributor block 2, prevent gas leakage, ensure that the sealing performance is not affected by thread wear and looseness, and increase the durability and reliability of the threaded connection.
[0032] Furthermore, a joint pressure plate 7 is provided above the gas distributor block 2, and a slot is provided on the joint pressure plate 7. A circle of grooves is provided above the thread of the rotary joint 6, and the slot of the joint pressure plate 7 can be inserted into the groove of the rotary joint 6. The joint pressure plate 7 is inserted into the groove of the rotary joint 6, so that the rotary joint 6 can rotate around the gas distributor block 2 without falling out, thereby realizing the rotation function of the pipeline interface.
[0033] It is connected to the low-pressure air supply component 3 and the high-pressure air supply component 4 respectively through the rotary joint 6, so that it can be rotated at will during air supply, and connected in accordance with the position of the external air supply device, so as to facilitate the adjustment of different positions of the mechanism, thereby increasing the flexibility of the system and making the connection of pipelines or equipment easier, thereby improving operating efficiency and production efficiency.
[0034] Please continue to refer to Figure 1 as well as Figure 2 The low-pressure air supply component 3 and the high-pressure air supply component 4 can be rotated and changed in direction at will by being connected to the rotary joint 6.
[0035] The low-pressure gas supply component 3 includes a low-pressure straight-through quick-connect fitting 33, a low-pressure solenoid valve 32 and a low-pressure proportional valve 31, and the low-pressure proportional valve 31 is connected to the rotary joint 6 through a double external threaded joint 5. Thus, in the low-pressure gas supply component 3, the low-pressure straight-through quick-connect fitting 33, the low-pressure solenoid valve 32 and the low-pressure proportional valve 31 are connected in sequence, and the low-pressure gas enters through the low-pressure straight-through quick-connect fitting 33, controls the switch through the low-pressure solenoid valve 32, and then the low-pressure proportional valve 31 controls the output ratio, and then enters the integrated gas outlet block 1 through the rotary joint 6.
[0036] The low-pressure gas pipeline of the external gas delivery device is connected to the low-pressure straight-through quick-connect connector 33 at the low-pressure end. When the laser head needs low-pressure gas for cutting assistance, the low-pressure solenoid valve 32 is opened, and the high-pressure solenoid valve 42 in the high-pressure gas supply component 4 is blocked; the low-pressure gas enters the low-pressure proportional valve 31, and is proportionally adjusted and output. According to the set proportional output, it passes through the rotary joint 6, the gas distribution block 2 and the built-in one-way valve 21 inside it in turn to enter the integrated gas outlet block 1, and finally outputs the gas to the laser head for use through the right-angle quick-connect plug 11. In addition, the built-in one-way valve 21 in the other gas distribution block 2 can block the low-pressure gas from flowing back to the high-pressure channel.
[0037] Similarly, in the high-pressure gas supply component 4, a high-pressure straight-through quick-plug connector 43, a high-pressure solenoid valve 42 and a high-pressure proportional valve 41 are included, and the high-pressure proportional valve 41 is connected to the rotary connector 6 through a double external threaded connector 5. Thus, in the high-pressure gas supply component 4, the high-pressure straight-through quick-plug connector 43, the high-pressure solenoid valve 42 and the high-pressure proportional valve 41 are connected in sequence, and the high-pressure gas enters through the high-pressure straight-through quick-plug connector 43, passes through the high-pressure solenoid valve 42 to control the switch, and then the high-pressure proportional valve 41 controls the output ratio, and then enters the integrated gas outlet block 1 through the rotary connector 6.
[0038] The high-pressure gas pipeline of the external gas delivery device is connected to the high-pressure straight-through quick-connect connector 43 at the high-pressure end. When the laser head needs high-pressure gas for cutting assistance, the high-pressure solenoid valve 42 is opened, and the low-pressure solenoid valve 32 in the low-pressure gas supply component 3 is blocked; the high-pressure gas enters the high-pressure proportional valve 41, and is proportionally adjusted and output. According to the set proportional output, it passes through the rotary joint 6, the gas distribution block 2 and the built-in one-way valve 21 inside it in turn to enter the integrated gas outlet block 1, and finally outputs the gas to the laser head for use through the right-angle quick-connect plug 11. In addition, the built-in one-way valve 21 in the other gas distribution block 2 can block the high-pressure gas from flowing back to the low-pressure channel.
[0039] Please refer to Figure 3 as well as Figure 4 The low-pressure gas supply component 3 and the high-pressure gas supply component 4 are connected to the integrated gas outlet block 1, and the gas outlet positions are gathered at the same position. A two-in-one channel 12 is provided in the integrated gas outlet block 1, and two inlets are provided in the two-in-one channel 12, and an outlet is provided in one channel. Among them, the two gas separation blocks 2 are respectively connected to the inlets of the two-in-one channel 12, and the gases delivered by the low-pressure gas supply component 3 and the high-pressure gas supply component 4 enter the corresponding inlets from the two gas separation blocks 2, and then enter the two-in-one channel 12.
[0040] Furthermore, a right-angle quick-connect plug 11 is provided at the integrated gas outlet block 1 to output the gas to the laser head terminal for use. The right-angle quick-connect plug 11 is correspondingly connected to the outlet of the two-in-one channel 12 so that the gas is output from the right-angle quick-connect plug 11.
[0041] A built-in one-way valve 21 is provided on the gas distribution block 2 connected to the integrated gas outlet block 1 to prevent the residual gas in the two-in-one channel 12 from flowing back when switching the gas.
[0042] In the gas circuit integrated device of the utility model, by respectively arranging the low-pressure gas supply component 3 and the high-pressure gas supply component 4 on the integrated gas outlet block 1, the proportional output of the high-pressure or low-pressure auxiliary gas required by the laser head can be covered at the same time, and the switching can be performed back and forth. Batches of materials of different thicknesses and different materials can be processed on the same device.
[0043] The high-pressure and low-pressure pipelines can be connected at the same time, and the high-pressure solenoid valve 42 and the low-pressure solenoid valve 32 can be controlled to switch the high-pressure and low-pressure auxiliary gas output of the laser head. And through the setting of the high-pressure proportional valve 41 and the low-pressure proportional valve 31, the ratio of the output gas can be controlled.
[0044] Furthermore, by providing the rotary joint 6, the pipeline interface can realize free rotation, thereby increasing the flexibility of the system and making the connection of pipelines or equipment easier, thereby improving the operating efficiency and production efficiency.
