Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, specifically a cooling device for an automotive parts cutting device. Background Technology

[0002] Automotive parts cutting equipment is typically used in the automotive parts manufacturing process to cut metal sheets or other materials to produce parts of the required shape and size. This includes CNC cutting machines, laser cutting machines, and plasma cutting machines. These different cutting methods have their own characteristics and applicable scope. CNC cutting machines, using numerical control technology, control the cutting tool along a specific path through pre-programmed instructions. They offer high precision and are suitable for cutting various metal materials. They can be used to cut different types of automotive parts, such as body panels, engines, chassis, and interior trim, to meet the processing needs of automotive manufacturing and assembly. When cutting parts, CNC cutting machines usually require a cooling device to spray coolant onto the surface of the cutting tool and the parts. This not only cools the tool and workpiece surfaces but also lubricates, reduces friction, cleans the workpiece surface, and removes chips.

[0003] Currently, most coolants contain surfactants or adhesives. These substances enable the coolant to better adhere to the surface of the cutting tool and workpiece during cutting or machining, forming a protective film. However, when metal powder generated during cutting flows through the circulation pipes with the coolant, some of the metal powder will be deposited or adhered to the pipe walls. The deposition of metal powder will gradually block the coolant circulation pipes, reduce the flow efficiency of the coolant, affect the cooling effect, and even lead to equipment failure.

[0004] Therefore, we propose a cooling device for automotive parts cutting equipment to solve the problems mentioned above. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-7The present invention provides a technical solution: a cooling device for an automotive parts cutting apparatus, comprising a coolant tank 1 and a three-way connector 3. A solvent tank 5 is fixedly installed on the top of the coolant tank 1 near the left side. A second suction pump 51 is fixedly installed on the top of the solvent tank 5 near the left side. A solvent supply pipe 52 is externally connected to the second suction pump 51. A fourth solenoid valve 53 is fitted on the outer surface of the solvent supply pipe 52. A filter 54 is fixedly installed on the top of the solvent tank 5 near the right side. A solvent return pipe 55 is fitted externally to the filter 54. A fifth solenoid valve 53 is fitted externally to the solvent return pipe 55. A solenoid valve 56 is fixedly connected to a second series pipe 72 at its end. A first suction pump 4 is fixedly installed on the top of the coolant tank 1, located behind the solvent tank 5. A coolant supply pipe 41 is externally connected to the first suction pump 4. A third solenoid valve 42 is externally connected to the coolant supply pipe 41. An inlet pipe 31 is fixedly connected to the top of the tee connector 3 near the left side. An outlet pipe 32 is fixedly connected to the top of the tee connector 3 near the right side. A first solenoid valve 33 is externally connected to the outlet pipe 32. An inlet pipe 31 is fixedly connected to the end of the coolant supply pipe 41. A liquid outlet hose 73 is fixedly connected between the ends of hose 71, outlet hose 32, and the second series hose 72. By closing the third solenoid valve 42 and the second solenoid valve 36, and then opening the fourth solenoid valve 53, the fifth solenoid valve 56, and the first solenoid valve 33, the solvent supply hose 52, the first series hose 7, the coolant supply hose 41, the inlet hose 71, the inlet hose 31, the outlet hose 32, the outlet hose 73, the solvent return hose 55, the filter 54, and the solvent tank 5 are connected to form a closed loop. By starting the second suction pump 51, the metal solvent is circulated in the closed loop. When the metal solvent passes through... When the coolant supply pipe 41, inlet hose 71 and inlet pipe 31 in the closed loop flow channel are flushed, the main pipes through which the coolant passes can be flushed. The metal solvent dissolves and loosens the metal powder in the inner wall of the pipe. Under the action of the fluid, the metal powder enters the filter 54. The filter 54 can separate the solvent and the powder. The separated solvent finally enters the solvent tank 5, thus achieving the effect of recycling the metal solvent and reducing the cost of consumables. The metal solvent is an alkaline solution, such as sodium hydroxide or ammonia, which has good dissolving power for metal powder and can effectively clean the pipes without damaging the pipes themselves.

[0023] like Figure 3 and Figure 4As shown, a housing 12 is fixedly installed on the top of the coolant tank 1 near the right side. A wedge 14 is provided on the bottom inner side of the housing 12. Four pillars 19 are fixedly installed on the top of the wedge 14. A worktable 16 is fixedly installed between the tops of the four pillars 19.

The table surface of the worktable 16 is horizontal and has multiple positioning holes and slots for installing special fixtures. The worktable 16 is also equipped with a Z-axis servo motor, a lead screw, and a guide rail, mainly to facilitate Z-axis displacement during the cutting process. The multi-axis robotic arm 17 is mainly composed of X-axis and Y-axis servo motors, a lead screw, and a guide rail, mainly to facilitate X-axis and Y-axis displacement during the cutting process. At the same time, the multi-axis robotic arm 17 is also equipped with a spindle and a cutting tool, and its main function is to cut automotive parts.

[0024] like Figure 3 and Figure 4 As shown, a rectangular hole 13 is provided through the bottom of the coolant tank 1 near the rear side, and a return hole 15 is provided through the top of the inclined block 14 near the rear side. The rectangular hole 13 and the return hole 15 are connected. The cut debris is flushed onto the inclined block 14 by the coolant and flows into the chip conveyor 11 through the rectangular hole 13 and the return hole 15 in sequence. The inclined block 14 is inclined downward from front to back, which can improve the efficiency and effect of debris discharge and avoid debris accumulation.

[0025] like Figure 1 As shown, a controller 18 is fixedly installed on the front surface of the housing 12, and a chip conveyor 11 is provided on the rear surface of the coolant tank 1. The coolant tank 1 is connected to the chip conveyor 11, and the opening of the chip conveyor 11 is connected to the rectangular hole 13. Through the system program in the controller 18, the multi-axis robotic arm 17 can be controlled to perform linkage, thereby achieving the function of precise cutting. The chip conveyor 11 is mainly composed of a drive motor, a chain scraper, and a chip removal channel. It is located in the top area below the housing 12 and has an opening that is connected to the rectangular hole 13 and has a corresponding opening. When the chip conveyor 11 is started, it can discharge the chips to achieve the effect of filtration. The filtered coolant enters the coolant tank 1 and, together with the first suction pump 4, runs continuously to achieve the effect of circulating the coolant.

[0026] like Figure 5 As shown, a bracket 2 is fixedly installed on the front surface of the multi-axis robotic arm 17, and a three-way connector 3 is installed on the outer surface of the bracket 2. The bracket 2 serves to install the three-way connector 3, and the bracket 2 is located on the beam wall above the main shaft of the multi-axis robotic arm 17.

[0027] like Figure 6As shown, the bottom of the three-way connector 3 is fixedly connected to a connecting pipe 34. A second solenoid valve 36 is provided on the outside of the connecting pipe 34. The bottom end of the connecting pipe 34 is threadedly connected to the spray pipe 35. The spray pipe 35 and the connecting pipe 34 are threadedly connected, which makes it easy to disassemble the spray pipe 35 and facilitates the maintenance or replacement of the spray pipe 35 in the future. The end of the spray pipe 35 is equipped with a nozzle, and the nozzle faces the cutting tool of the multi-axis robotic arm 17, so that the coolant can effectively spray and cool the cutting part.

[0028] like Figure 7 As shown, a cleaning fluid tank 6 is fixedly installed on the top of the coolant tank 1 in front of the solvent tank 5. A third suction pump 61 is installed on the top of the cleaning fluid tank 6 near the left side. The cleaning fluid tank 6 is filled with special cleaning fluid, and a filling port is provided on its top for easy replenishment of cleaning fluid or internal maintenance. The third suction pump 61 is mainly used to extract the cleaning fluid from the cleaning fluid tank 6.

[0029] like Figure 7 As shown, the third suction pump 61 is externally equipped with a cleaning fluid supply pipe 62, and the cleaning fluid supply pipe 62 is externally equipped with a sixth solenoid valve 63. A first series pipe 7 is fixedly connected between the end of the cleaning fluid supply pipe 62 and the solvent supply pipe 52. The end of the first series pipe 7 is connected to the coolant supply pipe 41. After the cleaning fluid supply pipe 62 is connected to the first series pipe 7, it mainly supplies the cleaning fluid to the outside to ensure the rationality of the circulation system. The first series pipe 7 mainly undertakes the external supply of metal solvent or cleaning fluid in stages to ensure the rationality of the circulation system.

[0030] like Figure 7 As shown, a cleaning fluid return pipe 64 is fixedly connected to the top of the cleaning fluid tank 6 near the right side. A seventh solenoid valve 65 is installed on the outside of the cleaning fluid return pipe 64. The end of the cleaning fluid return pipe 64 is connected to the second series pipe 72. The cleaning fluid return pipe 64 mainly transports the returned cleaning fluid to the cleaning fluid tank 6 to ensure the rationality of the circulation system.

[0031] like Figure 1-7 As shown, the controller 18 is electrically connected to the first solenoid valve 33, the second solenoid valve 36, the third solenoid valve 42, the fourth solenoid valve 53, the fifth solenoid valve 56, the sixth solenoid valve 63, the seventh solenoid valve 65, the first suction pump 4, the second suction pump 51, and the third suction pump 61. During normal cutting, the second solenoid valve 36 and the third solenoid valve 42 are normally open, while the first solenoid valve 33, the fourth solenoid valve 53, the fifth solenoid valve 56, the sixth solenoid valve 63, and the seventh solenoid valve 65 are normally closed.

[0032] The device's operation and working principle are as follows: A special fixture for automotive parts is installed on the workbench 16, and the parts are fixed to the fixture. The system program in the controller 18 controls the multi-axis robotic arm 17 to work in conjunction with the cutting tool to cut the automotive parts. During the cutting process, the first suction pump 4 pumps the coolant from the coolant tank 1 to the coolant supply pipe 41. The coolant then flows sequentially through the inlet hose 71, inlet pipe 31, and connecting pipe 34, finally being sprayed from the spray nozzle of the spray pipe 35 towards the cutting position, thus achieving cooling and lubrication. The cut parts... The debris is flushed onto the inclined block 14 by the coolant and flows into the chip conveyor 11 through the return hole 15. The chip conveyor 11 can discharge the debris, achieving a filtering effect. The filtered coolant enters the coolant tank 1 and, in conjunction with the first suction pump 4, continuously operates, achieving the effect of coolant circulation. When it is necessary to clean the metal powder on the inner wall of the circulation pipe, firstly, the third solenoid valve 42 and the second solenoid valve 36 are closed, and then the fourth solenoid valve 53, the fifth solenoid valve 56, and the first solenoid valve 33 are opened. At this time, the solvent supply pipe 52, the first series pipe 7, the coolant supply pipe 41, the inlet hose 71, the inlet pipe 31, and the outlet... The liquid pipe 32, liquid outlet hose 73, solvent return pipe 55, filter 54, and solvent tank 5 are connected to form a closed-loop flow channel. By starting the second suction pump 51, the metal solvent is circulated within the closed-loop flow channel. When the metal solvent passes through the coolant supply pipe 41, inlet hose 71, and inlet pipe 31 in the closed-loop flow channel, it flushes the main pipes through which the coolant passes. The metal solvent dissolves and loosens the metal powder on the inner wall of the pipes. Under the action of the fluid, the metal powder enters the filter 54, which separates the solvent and powder. The separated solvent finally enters the solvent tank 5, thus playing a role in... The recycling of metal solvent reduces consumable costs. After the solvent recycling is complete, the fourth solenoid valve 53 and the fifth solenoid valve 56 are closed, and the sixth solenoid valve 63 and the seventh solenoid valve 65 are opened. At this time, the cleaning fluid tank 6 becomes the path point of the new closed loop flow channel. By starting the third suction pump 61, the cleaning fluid is circulated in the closed loop flow channel. The cleaning fluid can flush away the residual metal solvent in the closed loop flow channel, preventing the metal solvent from mixing with the coolant and causing the coolant to deteriorate. At the same time, it further improves the cleanliness of the inner wall of the pipe. By disassembling the spray pipe 35 from the connecting pipe 34, it is convenient to maintain or replace the spray pipe 35.

The appropriate model is selected according to actual use. Therefore, the control methods and wiring arrangements of the controller 18, first solenoid valve 33, second solenoid valve 36, third solenoid valve 42, fourth solenoid valve 53, fifth solenoid valve 56, sixth solenoid valve 63, seventh solenoid valve 65, first suction pump 4, second suction pump 51, and third suction pump 61 will not be explained in detail.
