Description

Technical Field

[0001] This utility model relates to the field of pipe cutting machine technology, specifically a lubrication and cooling device for the cutting wheel of a pipe cutting machine. Background Technology

[0002] A pipe cutter is a device specifically designed for cutting pipes made of materials such as metal, plastic, glass, and ceramics. It can cut pipes to the required length and size in a short time. The cutting wheel is an important component of the pipe cutter and is mainly used for cutting metal or non-metal pipes. When cutting pipes, the high-speed rotation of the cutting wheel comes into contact with the pipe, generating a large amount of high temperature. In order to extend the service life of the cutting wheel, a lubrication and cooling device is needed to lubricate and cool the cutting wheel to reduce friction between the cutting wheel and the pipe.

[0003] Currently, existing lubrication and cooling devices typically spray cutting fluid onto the cutting wheel to lubricate and cool it. However, during the cutting process, the high-speed rotation of the cutting wheel causes the cutting fluid sprayed on its surface to fly backward, resulting in significant waste of cutting fluid. Moreover, the flying cutting fluid seriously affects the work of the operators. Utility Model Content

[0004] The purpose of this invention is to provide a lubrication and cooling device for the cutting wheel of a pipe cutter, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lubrication and cooling device for a pipe cutting machine's cutter wheel includes an operating table. A U-shaped frame is fixedly connected to the top surface of the operating table. Electric push rods are fixedly connected to both ends of the inner top surface of the U-shaped frame. A movable plate is fixedly connected between the output ends of the two electric push rods. A cutting mechanism is fixedly connected to the bottom surface of the movable plate. A storage tank for storing lubricating oil is fixedly connected to the top surface of the U-shaped frame. A lubrication mechanism for lubricating the cutter wheel in the cutting mechanism is provided on the bottom surface of the movable plate. A cooling mechanism for cooling the lubricating oil in the lubrication mechanism is provided on the top surface of the U-shaped frame.

[0007] The lubrication mechanism includes four rectangular fixed frames, with the cutter wheel located between the four fixed frames. A collection shell is fixedly connected to the bottom surface of each fixed frame, and the interior of the collection shell communicates with the interior of the corresponding fixed frame. A sponge that contacts the cutter wheel is detachably connected to the interior of each fixed frame. Connecting plates that are fixedly connected to a moving plate are fixedly connected to both ends of the top surface of each fixed frame. A circulation assembly is provided between the four fixed frames and the storage box.

[0008] Furthermore, the circulation component includes two U-shaped connecting pipes, the two ends of which are respectively fixed to the fixed frame at the corresponding position. A T-shaped pipe is fixedly connected to the outer wall of the connecting pipe, and a conduit is fixedly connected between the two T-shaped pipes. A T-shaped pipe is fixedly connected to the outer wall of the conduit, and one end of the T-shaped pipe is fixedly connected to a connecting pipe that penetrates and is fixed to the bottom surface of the storage box.

[0009] Furthermore, a connecting pipe 2 is fixedly connected between the inner bottom surfaces of the two collection shells located on the same side of the cutter wheel. A three-way pipe 3 is fixedly connected to the outer wall of the connecting pipe 2. A conduit 2 is fixedly connected between the two three-way pipes 3. A three-way pipe 4 is fixedly connected to the outer wall of the conduit 2. One end of the three-way pipe 4 is fixedly connected to a connecting pipe 2 that penetrates and is fixed to the top surface of the U-shaped frame. A pump body is fixedly connected to the side of the storage box. The input end of the pump body penetrates and is fixed to the storage box. The output end of the pump body is fixedly connected to the connecting pipe 2.

[0010] Furthermore, both the first connecting pipe and the second connecting pipe are flexible hoses.

[0011] Furthermore, a plurality of heat-conducting sheets are fixedly and evenly spaced through one side of the storage box, and a heat-conducting plate is fixedly connected between one end of the plurality of heat-conducting sheets. The cooling mechanism includes an L-shaped housing that reciprocates along the height direction of the heat-conducting plate, and a sponge that contacts the heat-conducting plate is detachably connected inside the L-shaped housing.

[0012] Furthermore, the top surface of the C-shaped frame is fixedly connected to two symmetrical L-shaped plates, and both ends of the L-shaped shell are fixedly connected to connecting blocks. One of the L-shaped plates is rotatably connected to the C-shaped frame and is screwed into the connecting block at the corresponding position. The top surface of the L-shaped plate corresponding to the reciprocating screw is fixedly connected to a motor. The other L-shaped plate is fixedly connected to the C-shaped frame and is slidably connected to the connecting block at the corresponding position.

[0013] Furthermore, fans are fixedly connected to both ends of the inner top surface of the L-shaped shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By allowing the lubricating oil to flow from the circulation component into the sponge under its own gravity, the sponge becomes saturated, which can lubricate the cutting wheel and prevent the lubricating oil from being thrown out in large quantities by the cutting wheel. Then, the excess lubricating oil is pumped into the storage tank through the circulation component. At the same time, the lubricating oil in the storage tank is cooled by the cooling mechanism, so that the cooled lubricating oil has a better heat absorption effect on the cutting wheel.

[0016] 2. By filling the L-shaped housing with water or alcohol, the sponge can apply the water or alcohol to the heat-conducting plate, absorbing the heat on the heat-conducting plate. At the same time, the action of two fans can accelerate the rapid evaporation of water or alcohol on the heat-conducting plate, which can quickly cool down the lubricating oil in the storage box, thereby facilitating the absorption of heat from the cutting wheel.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7In this embodiment of the utility model, a lubrication and cooling device for a pipe cutting machine cutter wheel includes an operating table 1. A U-shaped frame 2 is fixedly connected to the top surface of the operating table 1. Electric push rods 21 are fixedly connected to both ends of the inner top surface of the U-shaped frame 2. A moving plate 22 is fixedly connected between the output ends of the two electric push rods 21. A cutting mechanism 3 is fixedly connected to the bottom surface of the moving plate 22. A storage box 4 for storing lubricating oil is fixedly connected to the top surface of the U-shaped frame 2. A lubrication mechanism 5 for lubricating the cutter wheel in the cutting mechanism 3 is provided on the bottom surface of the moving plate 22. A cooling mechanism 6 for cooling the lubricating oil in the lubrication mechanism 5 is provided on the top surface of the U-shaped frame 2.

[0027] The lubrication mechanism 5 includes four rectangular fixed frames 51, with the cutter wheel located between the four fixed frames 51. A collection shell 52 is fixedly connected to the bottom surface of the fixed frame 51, and the interior of the collection shell 52 communicates with the interior of the fixed frame 51 at the corresponding position. A sponge 53 that contacts the cutter wheel is detachably connected to the interior of the fixed frame 51. A connecting plate 54 that is fixedly connected to the moving plate 22 is fixedly connected to both ends of the top surface of the fixed frame 51. A circulation component is provided between the four fixed frames 51 and the storage box 4.

[0028] Specifically, a certain amount of lubricating oil is first poured into the storage tank 4. A portion of the lubricating oil, under its own gravity, flows through the circulation component into the four sponges 53. Since the sponges 53 are in contact with the cutting wheel, the lubricating oil in the sponges 53 diffuses until the sponges 53 can coat the cutting wheel with the lubricating oil. Because the lubricating oil in the storage tank 4 continues to flow into the four sponges 53 under its own gravity, when the sponges 53 are saturated with lubricating oil, the lubricating oil in the sponges 53 will drip into the collection shell 52 at the corresponding position. Then, under the action of the circulation component, it is drawn back into the storage tank 4. Since the cutting wheel generates a large amount of heat during cutting, this heat is transferred to the lubricating oil in the sponges 53. Therefore, through circulation... The lubricating oil drawn into the storage tank 4 by the ring assembly will be at a relatively high temperature, which will cause the temperature of all the lubricating oil in the storage tank 4 to rise. At this time, the lubricating oil in the storage tank 4 can be cooled by the cooling mechanism 6, so that the cooled lubricating oil has a better heat absorption effect on the cutting wheel. This device allows the lubricating oil to flow from the circulation assembly into the sponge 53 under its own gravity, so that the sponge 53 reaches a saturated state, which can achieve the lubricating effect of applying lubricating oil to the cutting wheel and prevent the lubricating oil from being thrown out in large quantities by the cutting wheel. Then, the excess lubricating oil is drawn into the storage tank 4 by the circulation assembly, and the lubricating oil in the storage tank 4 is cooled by the cooling mechanism 6, so that the cooled lubricating oil has a better heat absorption effect on the cutting wheel.

[0029] Example 1

[0030] like Figure 4 and Figure 5 As shown, in this embodiment, the circulation assembly includes two U-shaped connecting pipes 55. Both ends of the connecting pipes 55 are respectively fixed through to a corresponding fixed frame 51. A T-shaped pipe 551 is fixedly connected to the outer wall of the connecting pipes 55. A conduit is fixedly connected between the two T-shaped pipes 551. A second T-shaped pipe 552 is fixedly connected to the outer wall of the first conduit. One end of the second T-shaped pipe 552 is fixedly connected to a connecting pipe 56 that penetrates and is fixed to the inner bottom surface of the storage tank 4. The inner bottom surfaces of the two collection shells 52 located on the same side of the cutter wheel are fixedly connected... A connecting pipe 2 57 is fixedly connected. A three-way pipe 3 571 is fixedly connected to the outer wall of the connecting pipe 2 57. A conduit 2 is fixedly connected between the two three-way pipes 3 571. A three-way pipe 4 572 is fixedly connected to the outer wall of the conduit 2. A connecting pipe 2 58 is fixedly connected to one end of the three-way pipe 4 572 and penetrates and is fixed to the top surface of the bracket 2. A pump body 59 is fixedly connected to the side of the storage box 4. The input end of the pump body 59 penetrates and is fixed to the storage box 4. The output end of the pump body 59 is fixedly connected to the connecting pipe 2 58. Both the connecting pipe 1 56 and the connecting pipe 2 58 are flexible hoses.

[0031] In this embodiment, the lubricating oil in the storage tank 4 can flow out under its own gravity through the connecting pipe 56, and then flow into the four sponges 53 through the three-way pipe 551 and the two-way pipe 552 respectively. When the sponge 53 is saturated, it can lubricate the cutting wheel. Since the lubricating oil in the storage tank 4 is continuously flowing downward, the saturated sponge 53 no longer absorbs lubricating oil. The excess lubricating oil is collected in the collection shell 52 at the corresponding position. The pump body 59 can pump the lubricating oil in the four collection shells 52 back into the storage tank 4. In this way, the cooling of the cutting wheel can be achieved through the circulation of lubricating oil.

[0032] Example 2

[0033] like Figure 3 As shown, in this embodiment, a plurality of heat-conducting sheets 41 are fixedly and evenly spaced through one side of the storage box 4, and a heat-conducting plate 42 is fixedly connected between one end of the plurality of heat-conducting sheets 41, such as... Figure 6 and Figure 7As shown, the cooling mechanism 6 includes an L-shaped housing 61 that reciprocates along the height of the heat-conducting plate 42. A sponge 62 that contacts the heat-conducting plate 42 is detachably connected inside the L-shaped housing 61. Two symmetrical L-shaped plates 23 are fixedly connected to the top surface of the frame 2. Connecting blocks 63 are fixedly connected to both ends of the L-shaped housing 61. A reciprocating screw 64 that is rotatably connected between one L-shaped plate 23 and the frame 2 and screwed into the corresponding connecting block 63 is connected to it. A motor 65 is fixedly connected to the top surface of the L-shaped plate 23 corresponding to the reciprocating screw 64. A limiting rod 67 that slides through the corresponding connecting block 63 is fixedly connected between the other L-shaped plate 23 and the frame 2. Fans 66 are fixedly connected to both ends of the inner top surface of the L-shaped housing 61.

[0034] In this embodiment, water or alcohol is first poured into the L-shaped housing 61, and then sponge 2 62 is inserted into the L-shaped housing 61 (e.g., Figure 7 As shown), at this time, the second sponge 62 absorbs water or alcohol, and the reciprocating screw 64 can be rotated by the motor 65. The rotating reciprocating screw 64 can make the L-shaped housing 61 move up and down, thereby making the second sponge 62 move up and down. The second sponge 62 can apply the absorbed water or alcohol to the heat-conducting plate 42. Since the temperature of the lubricating oil in the storage box 4 will be transferred to the heat-conducting plate 42 through multiple heat-conducting plates 41, the water or alcohol applied to the heat-conducting plate 42 can cool down the lubricating oil in the storage box 4. At the same time, by starting the two fans 66, the air can be blown onto the heat-conducting plate 42, which can accelerate the rapid evaporation of water or alcohol on the heat-conducting plate 42, so that the lubricating oil in the storage box 4 can be cooled down quickly, thus facilitating the absorption of heat from the cutting wheel.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
