Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machine head solenoid valve modules, in particular to a novel integrated head solenoid valve module. Background Art

[0002] Fiber laser cutting machine is a kind of equipment that uses laser technology for cutting. It is widely used in industrial production. The gas circuit in the fiber laser cutting machine is an important part of its normal operation. It plays a key role in adjusting cutting parameters and ensuring cutting quality and efficiency. The cutting gas pipeline is the channel for transmitting auxiliary gas to the fiber cutting head. The channel is usually composed of non-metallic hoses and plastic pipelines to ensure the stability and reliability of gas transmission. In the cutting gas pipeline, auxiliary devices such as filters, fluid control valves, electrical proportional valves, and one-way valves are also set to filter gas impurities, control gas on and off, adjust gas pressure and flow, and further control the cutting speed, thereby ensuring cutting quality and efficiency.

[0003] Components such as fluid control valves, electrical proportional valves, and one-way valves in the cutting gas circuit are often installed in the head of the optical fiber cutting machine in the form of modules, which are called head solenoid valve modules. In the head solenoid valve module, valves such as fluid control valves, electrical proportional valves, and one-way valves are often connected by hard joints (threads). Therefore, during the connection process, the threads are often filled by wrapping raw tape or applying thread glue at both ends of the joint to prevent leakage. However, in a high-pressure gas environment, long-term impact and friction often cause the raw tape or thread glue to powder, causing secondary contamination of the cutting gas, especially when the installer assembles the connection loosely and the threads are misaligned. In addition, when high-pressure gas is used continuously, there are often safety hazards such as air leakage, air leakage, and joint burst. Utility Model Content

DETAILED DESCRIPTION

[0033] In order to better explain the utility model and facilitate understanding, the utility model is described in detail below with reference to the accompanying drawings and through specific implementation methods. Figure 1 The orientation is used as a reference.

[0034] Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0035] like Figures 1 to 3 As shown, the utility model provides a new integrated head solenoid valve module, which includes a valve plate 1 and a plurality of solenoid valves. Among them, the valve plate 1 is an integrated structure, and a plurality of flow channels that are not connected to each other are opened inside the valve plate 1. A plurality of solenoid valves are arranged on the valve plate 1, and the solenoid valves and the valve plate 1 are sealed and connected by a seal. A plurality of solenoid valves are connected in series with a plurality of flow channels in sequence at intervals to form a gas control channel, which is applied to the scenario of controlling one gas; or only some of the solenoid valves are connected with some of the flow channels in sequence at intervals to form a plurality of parallel gas control channels, which is applied to the scenario of separately controlling multiple gas channels.

[0036] Specifically, different solenoid valves are used to control gas flow, pressure, flow rate and other parameters according to different usage scenarios. In a specific embodiment, multiple parallel gas control channels include control of low-pressure oxygen required for the laser cutting process and control of high-pressure argon or air for purging and protecting the cutting point.

[0037] The new integrated head solenoid valve module of the utility model integrates all valve groups into the valve block, and adopts the form of opening a flow channel inside the valve plate 1 to realize the connection between the valve groups, which overcomes the disadvantages and defects of relying on rigid connection between traditional valve plates 1; reduces the risk of air leakage, reduces the loss of pressure drop, and effectively avoids secondary pollution of gas. The new integrated head solenoid valve module has a reduced volume, strong integration, good durability, and long-term use of high-pressure gas without the danger of joint bursting. After reducing the rigid connection, the types of materials used are reduced, saving invisible costs such as procurement circulation and warehouse entry and exit labor hours, thereby effectively improving installation efficiency.

[0038] like Figure 2 As shown, the flow channel includes a first channel and at least one second channel that are interconnected. The opening of the first channel is located on the side of the valve plate 1 for easy processing. The opening of the second channel is located on the surface of the valve plate 1 where the solenoid valve is located. The inlet and outlet of the solenoid valve are both located at the bottom of the valve plate 1. After the solenoid valve is sealed and installed on the valve plate 1, the inlet and outlet at the bottom are sealed and connected with the openings of the two second channels one by one. All gas pipelines pass through the valve plate 1, and the original hard joints do not need to be used, which reduces the use of materials, the risk of air leakage, and quality risks.

[0039] Furthermore, the solenoid valve includes a low-pressure fluid control valve 2, a low-pressure electrical proportional valve 3 and a high-pressure fluid control valve 4. A threaded hole is provided on the valve plate 1, and the solenoid valve is connected to the valve plate 1 by bolts. The valve plate 1 is provided with a first flow channel 51, a second flow channel 52, a third flow channel 53 and a fourth flow channel 54. The opening of the first channel of the first flow channel 51 is the entrance of the oxygen path, and the first flow channel 51 includes a second channel; the opening of the first channel of the second flow channel 52 is blocked, and the second flow channel 52 includes two second channels; the opening of the first channel of the third flow channel 53 is connected to the laser head, and the third flow channel 53 includes two second channels; the opening of the first channel of the fourth flow channel 54 is the entrance of high-pressure argon or air, and the fourth flow channel 54 includes a second channel. The second channel of the first flow channel 51 is connected to the inlet of the low-pressure fluid control valve 2, the outlet of the low-pressure fluid control valve 2 and the inlet of the low-pressure electrical proportional valve 3 are respectively connected to the two second flow channels 52 of the second flow channel 52 in a one-to-one correspondence, and the outlet of the low-pressure electrical proportional valve 3 is connected to the second channel of the third flow channel 53, forming a control flow channel for low-pressure oxygen. The second channel of the fourth flow channel 54 is connected to the inlet of the high-pressure fluid control valve 4, and the outlet of the high-pressure fluid control valve 4 is connected to the second channel of the third flow channel 53, forming a control flow channel for high-pressure argon or air. The solenoid valve and the second channel can be abutted or sleeved by a sealing member.

[0040] See also Figure 2 The valve plate 1 is also provided with a fifth flow channel 55 and a sixth flow channel 56, each of which includes a second channel, and the first channel of the third flow channel 53 penetrates the first channels of the fifth flow channel 55 and the sixth flow channel 56. The outlet of the low-pressure electrical proportional valve 3 is connected to the second channel of the fifth flow channel 55, and the outlet of the high-pressure fluid control valve 4 is connected to the second channel of the sixth flow channel 56. A one-way valve 6 is provided in each of the fifth flow channel 55 and the sixth flow channel 56 to prevent the high-pressure gas in the nitrogen path from damaging the low-pressure equipment in the oxygen path when cutting with nitrogen; and also to prevent oxygen from flowing into the nitrogen pipeline and causing gas mixing when cutting with the oxygen path.

[0041] Oxygen circuit usage process: When cutting with oxygen, open the oxygen cylinder valve, and decompress the oxygen through the high-pressure reducing valve. After the oxygen is decompressed to 0.8MPa, it enters through the oxygen circuit inlet of valve plate 1, and then passes through Figure 2 The low-pressure fluid control valve 2 shown in the figure is controlled. The low-pressure fluid control valve 2 is a normally closed two-position two-way solenoid valve. When the fluid control valve is energized, the valve core inside the valve plate 1 will be attracted and lifted by the magnetic force, leaving a vent for oxygen to enter. The pressure is then adjusted through the low-pressure electrical proportional valve 3. After the gas flow is controlled, it flows to the gas outlet to the laser head to assist in cutting.

[0042] Nitrogen line use process: When cutting with nitrogen, open the Dewar tank or nitrogen bottle, and reduce the pressure through the high-pressure reducing valve. After the nitrogen is reduced to 2.5MPa, it enters from the nitrogen line inlet of valve plate 1, and then passes through Figure 2 The high-pressure fluid control valve 4 shown in the figure is controlled. The high-pressure fluid control valve 4 is a normally closed two-position two-way solenoid valve. When the fluid control valve is energized, the valve core inside the valve plate 1 will be attracted and lifted by the magnetic force, leaving a vent for oxygen to enter, and then flow to the outlet to the laser head to assist in cutting;

[0043] The utility model mainly focuses on the valve plate 1, which is designed according to the size of the valve type used in the gas circuit, the pressure resistance and the gas use process requirements. After the design is completed, a square aluminum alloy block is first cast, and then the gas inlet hole, the valve plate 1 installation and fixing hole, the valve plate 1 installation and fixing hole, the one-way valve 6 installation hole, etc. are constructed according to the design. After the hole construction is completed, the second flow channel 52, the fifth flow channel 55 and the sixth flow channel 56 are located on the side of the valve plate 1. The opening end is provided with a sealing cover, and a gland, a plug, an O-ring, a spacer, etc. are used for filling and sealing to prevent gas leakage.

[0044] Furthermore, the novel integrated head solenoid valve module of the utility model also provides a second implementation mode, see Figure 3 , which includes a valve plate 1 and a plurality of solenoid valves. The valve plate 1 is provided with a plurality of flow channels that are not interconnected with each other. Some solenoid valves are connected in series and connected to one of the plurality of flow channels. The interconnected solenoid valves are connected by conventional rigid connection. Similarly, the flow channel includes a first channel and a second channel that are interconnected. The opening of the first channel is located on the side of the valve plate 1, and the opening of the second channel is located on the surface of the valve plate 1 where the solenoid valve is located. The solenoid valve is connected to the opening of the second channel. A one-way valve 6 is arranged in the second channel to ensure that the multiple gases are independent of each other and do not interfere with each other. The one-way valve 6 in the head solenoid valve is integrated into the valve plate 1. The gas channel design is the same as the above-mentioned style. The implementation method is to connect the low-pressure electrical proportional valve 3 and the low-pressure fluid control valve 2 in the style of a rigid joint and then connect them to the second channel, and the high-pressure fluid control valve 4 is directly connected to the second channel. While reducing the use of rigid joints, the three-dimensional space of the head solenoid valve module is reduced, and it is more convenient to replace the fluid control valve and the low-pressure electrical proportional valve 3 damaged during use, which can effectively save installation time and improve installation efficiency.
