Description

Technical Field

[0001] This utility model relates to the technical field of ignition plates for flame cutting machines, specifically a dual-source dual-purpose cutting torch ignition plate. Background Technology

[0002] Flame cutting machines are cutting devices that use gas mixed with oxygen or gasoline mixed with oxygen to cut metal materials. They are mainly used in heavy industry and are mainly divided into early manual cutting (commonly known as oxygen welding) and semi-automatic cutting machines, profile cutting machines and CNC cutting machines. With social progress and technological development, they have become more and more advanced and their cutting functions have become more and more powerful.

[0003] Traditional ignition plates use flat copper plates for direct ignition, with the ignition core spraying out in all four directions at a 180-degree angle. This makes selective protection impossible, especially when igniting underwater, as oxygen is less likely to be blown away from the water at the ignition end of the burner to form an oxygen chamber. Utility Model Content

[0004] The purpose of this invention is to provide a dual-source, dual-purpose cutting torch ignition plate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-source dual-purpose cutting torch ignition plate, comprising an ignition core, a guide, a copper handle, a four-volt switch base, a plastic handle glove, a plug, a switch body, a waterproof cap, a high-temperature protective cover, a water-absorbing sponge for the protective cover, an evaporator, a plug, a high-temperature sleeve for the handle, screws, and a combustion rod. A copper handle is fixedly connected to one end of the four-volt switch base, and a guide is fixedly connected to the end of the four-volt switch base away from the copper handle. An ignition core is fixedly connected inside the guide, and a combustion rod is detachably connected inside the ignition core. A plug for isolation and protection is provided between the copper handle and the ignition core, and a high-temperature protective cover is detachably connected to the outside of the guide.

[0006] Furthermore, a screw is threadedly connected to the side of the guide away from the ignition core. The screw passes through the guide and is threadedly connected to the ignition core. The ignition core has a semi-circular triangular design and an oxygen guide groove is reserved inside the ignition core. The guide has a C-shaped structure and a flame core rebound blocking groove is reserved between the guide and the ignition core.

[0007] Furthermore, a water-absorbing sponge is fixedly connected inside the high-temperature protective cover, and an evaporator is fixedly connected inside the water-absorbing sponge. The evaporator has heat dissipation holes that are evenly distributed inside the evaporator.

[0008] Furthermore, a plug is fixedly connected to the outside of the high-temperature protective cover. The plug has a T-shaped groove structure on the back for easy insertion and removal of accessories. The evaporator is made of T-copper material.

[0009] Furthermore, a high-temperature sleeve for high-temperature protection is fixedly connected to the outside of the copper handle, and a plastic handle glove is detachably connected to the high-temperature sleeve.

[0010] Furthermore, both ends of the combustion rod are chamfered, the inside of the combustion rod is filled with metal wire and designed with a safe combustion distance, and the air inlet is designed with a safe distance of 3-5 cm.

[0011] Furthermore, a switch body is movably connected inside the four-way switch socket, and a waterproof cap is fixedly connected to the side of the switch body away from the four-way switch socket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model's ignition core is made of copper and features a semi-circular triangular design with an oxygen guide groove. The oxygen guide groove allows for vertical oxygen rebound, ensuring that the oxygen completely envelops the end face of the combustion rod. During underwater ignition, oxygen flows along the direction of the ignition core after all the water at the combustion end is drained. When the oxygen flows towards the switch end, it rebounds through the plug and flows in the opposite direction, making it easier to form a gas chamber during underwater ignition. The outward flow of oxygen also helps to cool the ignition core. The guide is also made of copper. During ignition, the flame core will be ejected outward along the oxygen direction due to the action of oxygen. The guide ensures that the flame core can only be ejected in a U-shaped direction, which also helps to cool the ignition core. The outer wall of the combustion rod has a chamfered structure to ensure that the combustion rod and the ignition wire of the ignition plate are in contact as close as possible to the inner surface of the oxygen outlet, making it easier for the oxygen to be enveloped. A safety distance of 3-5 cm is designed at the air inlet end. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Please see Figure 1 This utility model provides an embodiment of a dual-source dual-purpose cutting torch ignition plate, comprising an ignition core 1, a guide 2, a copper handle 3, a four-fluorocarbon switch base 4, a plastic handle glove 5, a plug 6, a switch body 7, a waterproof cap 8, a high-temperature protective cover 9, a protective cover absorbent sponge 10, an evaporator 11, a plug 12, a handle high-temperature sleeve 13, a screw 14, and a combustion rod 15. One end of the four-fluorocarbon switch base 4 is fixedly connected to the copper handle 3, and the other end of the four-fluorocarbon switch base 4 away from the copper handle 3 is fixedly connected to the guide 2. The ignition core 1 is fixedly connected inside the guide 2, and the combustion rod 15 is detachably connected inside the ignition core 1. A plug 6 for isolation and protection is provided between the copper handle 3 and the ignition core 1. The high-temperature protective cover 9 is detachably connected to the outside of the guide 2. The high-temperature protective cover 9 is made of high-temperature resistant four-fluorocarbon material and can hold water for water absorption. Both ends of the combustion rod 15 have a chamfered structure, and the combustion rod 15 is filled with metal wire and designed with a safe combustion distance. The air inlet end is designed with a 3-5 cm safe distance.

[0023] Reference Figure 2A high-temperature sleeve 13 for high-temperature protection is fixedly connected to the outside of the copper handle 3. The high-temperature sleeve 13 is detachably connected to a plastic handle glove 5. The copper handle 3 is made of copper tubing and is threadedly connected to the guide 2 to transfer the temperature from the ignition core 1 to the guide 2 and then to the copper handle 3. The end of the copper handle 3 is connected to a cable, and the space in the middle is filled with water-absorbing high-temperature sponge. Before use, the ignition plate is immersed in water to allow the sponge inside the copper handle 3 to absorb water, which can extend the service life. The switch body 7 is movably connected inside the four-way switch base 4. The side of the switch body 7 away from the four-way switch base 4 is fixedly connected to... The waterproof cap 8 and the four-way switch base 4 are mainly used to prevent sparks from bouncing back to the handle and also serve as heat insulation. The high-temperature protective cover 9 has a protective cover water-absorbing sponge 10 fixedly connected inside. The protective cover water-absorbing sponge 10 has an evaporator 11 fixedly connected inside. The evaporator 11 has heat dissipation holes 16 inside, which are evenly distributed inside the evaporator 11. The evaporator 11 is made of T2 copper to facilitate heat conduction and cooling, and to prevent damage to the protective cover water-absorbing sponge 10 when inserting or removing the ignition plate. The protective cover water-absorbing sponge 10 is made of flame-retardant asbestos material and can absorb water and cool down.

[0024] Reference Figure 3 and Figure 4 The high-temperature protective cover 9 has a fixed plug 12 on its outer side. The plug 12 has a T-shaped groove structure on the back for easy insertion and removal of accessories. The evaporator 11 is made of T2 copper. The plug 12 is directly fixed to the back plate with screws on the back. The guide 2 has a screw 14 threaded on the side away from the ignition core 1. The screw 14 passes through the guide 2 and is threaded to the ignition core 1. The ignition core 1 has a semi-circular triangular design and an oxygen guide groove 17 is reserved inside. The guide 2 has a C-shaped structure and a flame core rebound blocking groove 18 is reserved between the guide 2 and the ignition core 1. The ignition core 1 is made of copper. The function of the oxygen guide groove 17 is to allow oxygen to rebound vertically, so that the oxygen completely covers the end face of the combustion rod 15. When igniting underwater, the oxygen can flow along the direction of the ignition core 1 after all the water on the combustion end face is drained. When the oxygen flows towards the switch end, it rebounds through the plug 6 and flows in the opposite direction. Underwater ignition makes it easier to form a gas chamber. The oxygen flowing outward also serves to cool the flame. The guide 2 is made of copper. When igniting, the flame core will be sprayed outward along the direction of the oxygen due to the action of the oxygen. The presence of the guide makes the flame core spray only in a U-shaped direction, and also serves to cool the ignition core 1.

[0025] Example 2

[0026] Reference Figure 5 It is an automatic ignition plate, eliminating the need for a switch; instead, a flow sensor replaces the switch. When used with a cutting torch, oxygen flows through when the torch is turned on, activating the flow sensor and triggering a pulse current output from the battery.

[0027] The ignition core 1 adopts a semi-circular triangular design with an oxygen guide groove 17 on top. The guide 2 adopts a C-shape. The high-temperature protection cover 9 adopts a four-valve tube with a T-shaped quick slot on the outer wall. The base of the ignition plate is designed with a concave flame core rebound blocking groove 18. Both ends of the combustion rod 15 adopt a chamfered structure, and the inside is filled with metal wire and designed with a safe combustion distance. The air inlet end is designed with a 3-5CM safe distance.

[0028] Working principle: The ignition core 1 is made of copper. The oxygen guide groove 17 allows oxygen to rebound vertically, completely enveloping the end face of the combustion rod 15. During underwater ignition, oxygen flows along the direction of the ignition core 1 after all the water at the combustion end face is drained. When the oxygen flows towards the switch end, it rebounds through the plug 6 and flows in the opposite direction, making it easier to form a gas chamber during underwater ignition. The outward flow of oxygen also serves to cool the flame. The guide 2 is made of copper. During ignition, the flame core will be ejected outward along the oxygen direction due to the action of oxygen. The presence of the guide 2 ensures that the flame core can only be ejected in a U-shaped direction, and also serves to cool the ignition core 1. The outer wall of the combustion rod 15 is chamfered. The structure is designed to ensure that the burner 15 and the ignition wire of the ignition plate are in contact as close as possible to the inside of the oxygen outlet, making it easier for the oxygen to be contained. The air inlet is designed with a safety distance of 3-5 cm. When in use, after turning on the ignition switch, a 500A high-current pulse is instantly activated. The current will pass through the burner 15 to the ignition core 1 to form a closed loop. Since the burner 15 and the ignition core 1 achieve two-point contact, the contact resistance is the highest in the entire closed loop. When the high current passes through, it will generate heat, which will burn under the action of oxygen, igniting the burner 15. After the ignition plate is used, it will retain high temperature. It can be placed in the high-temperature protection cover 9 for storage and cooling, freeing up the hands when carrying the equipment.
