Description

Technical Field

[0001] This utility model relates to the field of CNC flame cutting technology, and in particular to a cooling device for CNC flame cutting machines. Background Technology

[0002] CNC flame cutting machines are machines that use digital programs to drive the movement of the machine tool, are equipped with a flame cutting system, and use a CNC system to control the switching of the flame cutting system. They are used to cut metal materials such as steel plates. CNC flame cutting machines have the advantages of cutting thick carbon steel and low cutting costs, so they are widely used in the machinery manufacturing industry. However, after a long period of use, the cutting head of a CNC flame cutting machine will get very hot and needs to be cooled down using a cooling device. In existing technologies, cooling devices mostly use water pipes to flush water into spray heads, which then spray the water onto the cutting head to achieve cooling. However, this results in water that has absorbed heat being sprayed directly onto the CNC flame cutting machine's worktable, making it impossible to collect and reuse, thus wasting water resources. Furthermore, the CNC flame cutting machine's worktable will corrode after repeated contact with large amounts of water. To address these issues, application number 202321744179.2 discloses a cooling device for a CNC flame cutting machine, which includes a first support rod and a lifting rod. A groove is provided on one side of the first support rod, and one end of the lifting rod is slidably connected inside the groove. A first drive assembly for driving the lifting rod to move up and down is provided at the top of the first support rod. A second support rod is welded to the middle of one side of the lifting rod, and a movable rod passes through the bottom of the other side of the lifting rod. This solution uses the cooperation of the first and second drive components to move the cooling cover up, down, left and right, so that the cooling cover covers the cutting head of the CNC flame cutting machine. Then, water from the external water inlet hose is discharged into the cooling cover through the water inlet pipe to cool the cutting head. At the same time, the water that has absorbed heat is discharged through the water outlet pipe and the external water outlet hose for reuse. However, a review of the aforementioned patent documents reveals the following drawbacks: in actual use, the flame cutting head needs to be moved to a specific area to achieve cooling, which has certain limitations. It also suffers from a complex structure and high maintenance costs, which need to be improved.

[0003] Therefore, this application proposes a cooling device for a CNC flame cutting machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for a CNC flame cutting machine, which can cool the flame cutting head as soon as the flame cutting head stops working.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cooling device for a CNC flame cutting machine, comprising a flame cutting head, a cylinder, and a cooling mechanism installed on the CNC flame cutting machine; The flame cutting head is equipped with a cooling mechanism, and a cylinder is installed on the flame cutting head. The cooling mechanism is connected to the cylinder. The cooling mechanism includes a sleeve, side lugs, a guide rod, a hinge, a sealing plate, a magnetic ring, an iron ring, a water inlet pipe, and a drain pipe. The sleeve is fitted onto the flame cutter head. Two side lugs are fixedly connected to one end of the sleeve. One end of the cylinder is fixedly connected to one of the two side lugs. A hinge is fixedly installed at the other end of the sleeve. A sealing plate is fixedly connected to one end of the hinge. One side of the sealing plate is in close contact with one end of the sleeve. Through the coordinated design of the flame cutter head, the cylinder, and the cooling mechanism, the flame cutter head can be cooled down as soon as it stops working, improving convenience and efficiency.

[0006] A further feature of this invention is that: a groove is formed on the top of the sealing plate, and an iron ring is fixedly installed in the groove; a second groove is formed at one end of the sleeve, and a magnetic ring is fixedly installed in the second groove. The magnetic ring corresponds to the iron ring, and the iron ring is attracted by the magnetic ring. Thus, through the magnetic force between the magnetic ring and the iron ring, the sealing plate and the sleeve are brought into closer contact, which not only improves the sealing performance but also increases the load-bearing capacity of the sealing plate.

[0007] A further feature of this invention is that a water inlet pipe is sealed to the top of the sleeve, which facilitates the delivery of cooling water into the sleeve.

[0008] A further feature of this invention is that a drain pipe is sealed to the bottom of the sleeve for draining hot water.

[0009] A further feature of this invention is that a guide rod is fixedly connected to one of the two side ears, and a fixing plate is slidably sleeved on the guide rod. The fixing plate is fixedly connected to the flame cutter and is used to guide and limit the sleeve.

[0010] A further feature of this invention is that two fixing plates are fixedly connected to the flame cutting head, and the cylinder is fixedly mounted on the two fixing plates for driving the sleeve.

[0011] A further feature of this invention is that the sealing plate is adapted to the sleeve, and torsion springs are installed at both ends of the hinge shaft. When the sealing plate disengages from the flame cutter, the elastic potential energy of the torsion springs at both ends of the hinge shaft causes the sealing plate to rotate at a certain angle and make the top of the sealing plate tightly contact one end of the sleeve, thereby achieving the effect of sealing only one end of the sleeve.

[0012] A further feature of this invention is that a sealing ring one and a sealing ring two are fixedly installed on the top of the sealing plate and one end of the sleeve, respectively, with the sealing ring one and the sealing ring two in close contact to improve the sealing performance.

[0013] A further feature of this invention is that a connecting plate is fixedly connected to the flame cutting head, and a mounting plate is fixedly connected to one end of the connecting plate. The mounting plate has multiple mounting holes, and the connecting plate and the mounting plate facilitate the installation of the flame cutting head on a CNC flame cutting machine.

[0014] The beneficial effects of this utility model are: through the coordinated design of the flame cutter, cylinder and cooling mechanism, the flame cutter can be cooled down at the same time as it stops working, which improves convenience and efficiency. Attached Figure Description

[0020] Reference Figures 1-4 A cooling device for a CNC flame cutting machine includes a flame cutting head, a cylinder 2, and a cooling mechanism 3 installed on the CNC flame cutting machine. The flame cutter head 1 is equipped with a cooling mechanism 3, and a cylinder 2 is installed on the flame cutter head 1. The cooling mechanism 3 is connected to the cylinder 2. The cooling mechanism 3 includes a sleeve 31, side ears 32, guide rod 33, hinge 34, sealing plate 35, magnetic ring 36, iron ring 37, water inlet pipe 38, and drain pipe 39. The sleeve 31 is fitted onto the flame cutter 1. Two side ears 32 are fixedly connected to one end of the sleeve 31. One end of the cylinder 2 is fixedly connected to one of the two side ears 32. The other end of the sleeve 31 is fixedly installed with a hinge 34. One end of the hinge 34 is fixedly connected to a sealing plate 35. One side of the sealing plate 35 is in close contact with one end of the sleeve 31. Through the cooperative design between the flame cutter 1, the cylinder 2, and the cooling mechanism 3, the flame cutter 1 can be cooled down at the same time as it stops working, improving convenience and efficiency.

[0021] Referring to the attached diagram, the top of the sealing plate 35 has a groove 1, in which an iron ring 37 is fixedly installed. One end of the sleeve 31 has a groove 2, in which a magnetic ring 36 is fixedly installed. The magnetic ring 36 corresponds to the iron ring 37, and the iron ring 37 is attracted by the magnetic ring 36. Thus, through the magnetic force between the magnetic ring 36 and the iron ring 37, the sealing plate 35 and the sleeve 31 are brought into closer contact, which not only improves the sealing performance but also increases the load-bearing capacity of the sealing plate 35. The appropriate magnet material should be selected according to the specific working temperature to avoid magnetic failure due to high temperature.

[0022] Referring to the attached drawings, the top of the sleeve 31 is sealed with a water inlet pipe 38 to facilitate the delivery of cooling water into the sleeve 31. The water inlet pipe 38 is connected to the water pump on the cooling water tank via a hose. The bottom of the sleeve 31 is sealed with a drain pipe 39 to discharge hot water. The drain pipe 39 is connected to the collection inlet via a delivery pipe. The amount of water delivered into the sleeve 31 by the water inlet pipe 38 is equal to the amount of water discharged by the drain pipe 39 to prevent cooling water from overflowing. The water inlet pipe 38, the drain pipe 39, the sealing plate 35, and the sleeve 31 are all made of ceramic material.

[0023] Referring to the attached drawings, a guide rod 33 is fixedly connected to one of the two side ears 32. A fixing plate 1 is slidably sleeved on the guide rod 33. The fixing plate 1 is fixedly connected to the flame cutter 1 and is used to guide and limit the sleeve 31.

[0024] Referring to the attached diagram, two fixing plates are fixedly connected to the flame cutter 1, and the cylinder 2 is fixedly installed on the two fixing plates to drive the sleeve 31.

[0025] Referring to the attached drawings, the sealing plate 35 is adapted to the sleeve 31. Both ends of the hinge 34 are equipped with torsion springs. When the sealing plate 35 is separated from the flame cutter 1, the elastic potential energy of the torsion springs at both ends of the hinge 34 causes the sealing plate 35 to rotate at a certain angle and make the top of the sealing plate 35 tightly contact one end of the sleeve 31, thereby achieving the effect of sealing only one end of the sleeve 31.

[0026] Referring to the attached drawings, sealing ring 1 and sealing ring 2 are fixedly installed on the top of the sealing plate 35 and one end of the sleeve 31, respectively. Sealing ring 1 and sealing ring 2 are in close contact to improve sealing performance.

[0027] Referring to the attached drawings, a connecting plate 4 is fixedly connected to the flame cutting head 1, and a mounting plate 5 is fixedly connected to one end of the connecting plate 4. The mounting plate 5 has multiple mounting holes, and the connecting plate 4 and the mounting plate 5 facilitate the installation of the flame cutting head 1 on the CNC flame cutting machine.

[0028] Working principle: When cooling is required at the end of the flame cutter, firstly, the extension drive of cylinder 2 and the coordinated transmission of guide rod 33 and two side ears 32 cause the sleeve 31 to move downward a certain distance. Simultaneously, the sleeve 31, through the transmission of hinge 34, drives the sealing plate 35 to move, placing it on the end of the flame cutter 1. During this process, as the sealing plate 35 disengages from the flame cutter 1, the elastic potential energy of the torsion springs at both ends of the hinge 34's rotating shaft causes the sealing plate 35 to rotate a certain angle, making the top of the sealing plate 35 tightly contact one end of the sleeve 31, thus achieving a sealing effect on the movement of the sleeve 31. Simultaneously, the magnetic ring 36 engages with the iron ring 37. Adsorption occurs, and through the magnetic force between the magnetic ring 36 and the iron ring 37, the sealing plate 35 and the sleeve 31 are brought into closer contact, which not only improves the sealing performance but also increases the load-bearing capacity of the sealing plate 35. Then, the water in the cooling water tank is drawn out and transported to the sleeve 31 by the water pump connected to the water inlet pipe 38. At this time, heat conduction occurs between the cooling water and the flame cutting head 1, thereby achieving the effect of cooling the flame cutting head 1. Afterward, through the action of the drain pipe 39 and its external conveying pipe, the hot water is discharged into the collection tank, which not only prevents the cooling water from falling onto the worktable of the CNC flame cutting machine but also facilitates the recycling of the cooling water.

[0029] After the flame cutter head 1 has cooled down, the supply of cooling water to the sleeve 31 is stopped. After the water in the sleeve 31 is drained, the cylinder 2 is reversed, causing the sleeve 31 to move upward a certain distance. During this process, the end of the flame cutter head 1 interacts with the sealing plate 35, causing the sealing plate 35 to rotate a certain angle around the hinge 34 pivot, and causing the torsion spring to rotate and store energy. At the same time, the sealing plate 35 is disengaged from the flame cutter head 1, thus enabling the flame cutter head to work normally.

[0030] The technological advancement of this invention compared to the prior art is that, through the cooperation of various components, the flame cutter 1 can be cooled down at the same time it stops working, which improves convenience and efficiency. Moreover, the structure is simple and more practical.
