Description

Technical Field

[0001] This utility model relates to the field of laser cutting, specifically a rapid cooling device for laser cutting machines. Background Technology

[0002] A laser cutting machine is a device that uses a laser beam as its energy source to cut materials using the high temperature generated by the laser. It focuses the laser emitted from the laser into a high-power-density laser beam through an optical path system, irradiating the surface of the workpiece until it reaches its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal, thus achieving the cutting purpose. To prevent damage from excessively high temperatures, a cooling device is needed. The "rapid cooling device for a laser cutting machine" disclosed in application number "202221282194.5" is an increasingly mature technology. It utilizes a rotating cooling spray gun that can rotate and spray air as needed to achieve a good air-jet cooling effect and improve cooling efficiency; through the setting of adjustable supports... The support frame can be slidably adjusted for stable movement during use, thus achieving a good cutting effect. However, this cooling device has the following drawbacks: while the cooling spray gun does achieve a cooling effect, the effect is not significant. Therefore, it is necessary to provide a cooling device that can significantly improve the cooling effect and enhance practicality. Furthermore, this cooling device is not convenient for position adjustment as needed to simultaneously cool the workpiece. Therefore, it is necessary to provide a cooling device that is easy to move, performs simultaneous cooling operations, and improves ease of use. Utility Model Content

[0003] This invention provides a rapid cooling device for laser cutting machines, aiming to address the issue that the cooling area and effect of existing cooling devices need improvement.

[0004] To achieve the above objectives, this utility model provides a rapid cooling device for a laser cutting machine, comprising a reciprocating assembly and a cooling assembly;

[0005] The reciprocating assembly includes a guide beam, a guide groove at the upper end of the guide beam, a guide block slidably connected inside the guide groove, a guide screw hole at one end of the guide block, a lead screw threaded inside the guide screw hole, and a transmission mechanism installed at one end of the lead screw.

[0006] A cooling component includes a connecting block, a water storage tank at the upper end of the connecting block, a high-pressure pump installed at the upper end of the connecting block, water supply pipes installed at both ends of the high-pressure pump, a high-pressure nozzle installed at the lower end of the water supply pipe, a conical spray hole inside the high-pressure nozzle, a laser nozzle installed at the lower end of the connecting block, a slope flange fixedly connected to the lower end of the laser nozzle, and a plurality of drainage holes equidistantly formed on the surface of the slope flange.

[0007] As a preferred embodiment of this utility model, the transmission mechanism includes a servo motor mounted on one end of a lead screw, and both the output end of the servo motor and one end of the lead screw are connected to synchronous pulleys, with synchronous belts connected to the side surfaces of both synchronous pulleys.

[0008] In a preferred embodiment of this utility model, both ends of the guide beam are fixedly connected to supports, and the servo motor is installed on one side of one of the supports.

[0009] As a preferred embodiment of this utility model, the lower end of the guide block is fixedly connected with a connecting bolt, the upper end of the connecting block is fixedly installed with a connecting bracket, the upper end of the connecting bracket is provided with a connecting screw hole, and the connecting bolt is threaded into the inside of the connecting screw hole.

[0010] As a preferred embodiment of this utility model, the water storage tank is equipped with a sealing cover, and the connecting block has two symmetrically arranged fitting grooves inside, with both water supply pipes installed inside the fitting grooves.

[0011] As a preferred embodiment of this utility model, the upper end of the connecting block is fixedly provided with a side edge, and both sides of the high-pressure pump and one end of the water supply pipe are fixedly connected with connecting flanges, and the high-pressure pump and the water supply pipe are connected through the connecting flanges.

[0012] As a preferred embodiment of this utility model, the conical nozzle and the sloping flange inside the high-pressure nozzle are vertically structured, and the drain hole is an inclined structure with the inclination direction matching that of the laser nozzle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When cooling the laser nozzle, cold water in the water tank is first pumped into the high-pressure nozzle through the water supply pipe by a high-pressure pump. The symmetrically arranged high-pressure nozzles spray water onto the laser nozzle from both sides. At the same time, the conical nozzle structure increases the spray pressure. The sprayed cooling water is directly sprayed onto the slope flange side surface, causing the cooling water to atomize and expand the cooling area. Some of the cooling water flows directly onto the surface of the laser nozzle through the water outlet of the inclined structure, which can achieve a rapid cooling effect. Compared with the cooling device in the existing technology "A rapid cooling device for a laser cutting machine", this utility model can easily expand the cooling area through the above structure and thus improve the cooling effect.

[0015] 2. When performing synchronous cooling of the workpiece, simply start the transmission mechanism to rotate the lead screw clockwise or counterclockwise, thereby controlling the guide block to reciprocate along the guide groove. As the guide block reciprocates with the connecting frame, it can move the cooling component, facilitating synchronous cooling of different positions on the workpiece. Compared with the cooling device in the existing technology "A Rapid Cooling Device for Laser Cutting Machine", this utility model, through the cooperation of the above structures, can facilitate real-time cooling of the workpiece, thereby improving the ease of use of the cooling device.

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 Figures 1-8 This utility model provides a rapid cooling device for a laser cutting machine, including a reciprocating assembly 100 and a cooling assembly 200;

[0027] The reciprocating assembly 100 includes a guide beam 101, a guide groove 102 is provided at the upper end of the guide beam 101, a guide block 103 is slidably connected inside the guide groove 102, a guide screw hole 105 is provided at one end of the guide block 103, a lead screw 104 is threadedly connected inside the guide screw hole 105, and a transmission mechanism 106 is installed at one end of the lead screw 104.

[0028] The cooling component 200 includes a connecting block 201. A water storage tank 202 is provided at the upper end of the connecting block 201. A high-pressure pump 203 is installed at the upper end of the connecting block 201. Water supply pipes 204 are installed at both ends of the high-pressure pump 203. A high-pressure nozzle 205 is installed at the lower end of the water supply pipe 204. A conical spray hole 206 is provided inside the high-pressure nozzle 205. A laser nozzle 207 is installed at the lower end of the connecting block 201. A slope flange 208 is fixedly connected to the lower end of the laser nozzle 207. A plurality of drainage holes 209 are equidistantly provided on the surface of the slope flange 208.

[0029] In one specific embodiment, the reciprocating component 100, in conjunction with the cooling component 200, not only facilitates expanding the cooling area but also enhances the cooling effect through cooling water, thus improving the practicality of the cooling device. Furthermore, the coordinated structure facilitates automatic synchronous cooling of the workpiece, thereby improving the ease of use of the cooling device. In operation, the transmission mechanism 106 is first activated, causing the lead screw 104 to rotate clockwise or counterclockwise, thereby controlling the guide block 103 to reciprocate along the guide groove 102, carrying the lower cooling component 200. Cooling water is pumped from the water storage tank 202 by the high-pressure pump 203 and transported through the water supply pipe 204. Finally, it is sprayed out through the high-pressure nozzles 205 installed symmetrically on both sides. At this time, the conical nozzles 206 can enhance the water pressure and improve the cooling effect. The sprayed cooling water can expand the cooling area by spraying onto the surface of the slope flange 208. Some of the cooling water flows out through the drain hole 209 of the inclined structure to assist in the cooling operation. At the same time, the reciprocating motion of the cooling component 200 can perform synchronous cooling operation on the workpiece, thereby improving the cooling effect and the ease of use of the cooling device.

[0030] Please see Figure 2 and Figure 3 The transmission mechanism 106 includes a servo motor 1061 mounted on one end of the lead screw 104. The output end of the servo motor 1061 and one end of the lead screw 104 are both connected to a synchronous pulley 1062. The side surfaces of the two synchronous pulleys 1062 are both connected to a synchronous belt 1063.

[0031] In one specific embodiment, by starting the servo motor 1061 to rotate the synchronous pulley 1062 at the output end, and cooperating with the synchronous belt 1063 to rotate another synchronous pulley 1062, the lead screw 104 can be rotated clockwise or counterclockwise, thereby improving the ease of use of the cooling device.

[0032] Please see Figure 2 and Figure 3 Both ends of the guide beam 101 are fixedly connected to supports 111, and the servo motor 1061 is installed on one side of one of the supports 111.

[0033] In one specific embodiment, the support 111 can improve the installation support stability of the guide beam 101, thereby improving the safety of the cooling device.

[0034] Please see Figure 2 and Figure 3 The lower end of the guide block 103 is fixedly connected to the connecting bolt 121, and the upper end of the connecting block 201 is fixedly installed with the connecting bracket 122. The upper end of the connecting bracket 122 is provided with a connecting screw hole 123, and the connecting bolt 121 is threaded into the inside of the connecting screw hole 123.

[0035] In one specific embodiment, the threaded connection of the connecting bolt 121 inside the connecting bolt hole 123 can improve the installation tightness and ease of disassembly between the guide block 103 and the connecting bracket 122.

[0036] Please see Figures 4-8 The water storage tank 202 is equipped with a sealing cover 211, and the connecting block 201 has two symmetrically arranged fitting grooves 212 inside, and the two water supply pipes 204 are installed inside the fitting grooves 212.

[0037] In one specific embodiment, the sealing cap 211 can seal the water storage tank 202, and the fitting groove 212 can limit the installation of the water supply pipe 204, thereby improving the stability of the water supply pipe 204 during the cooling water transportation process.

[0038] Please see Figures 4-8 The upper end of the connecting block 201 is fixedly provided with a side flange 221. Both sides of the high pressure pump 203 and one end of the water supply pipe 204 are fixedly connected with connecting flanges 222. The high pressure pump 203 and the water supply pipe 204 are connected through the connecting flanges 222.

[0039] In one specific embodiment, the connecting flange 222 can enhance the connection stability and ease of disassembly and replacement between the high-pressure pump 203 and the water supply pipe 204.

[0040] Please see Figures 4-8 The conical nozzle 206 and the sloping flange 208 inside the high-pressure nozzle 205 are vertical, and the drain hole 209 is inclined and the inclination direction matches that of the laser nozzle 207.

[0041] In one specific embodiment, the vertically structured conical nozzle 206, in conjunction with the sloped flange 208, can expand the cooling area of ​​the cooling water, while the inclined drain hole 209 facilitates the guidance of cooling water to contact the laser nozzle 207 for cooling operation.

[0042] Working principle: In use, the transmission mechanism 106 is first started to rotate the lead screw 104 clockwise or counterclockwise, thereby controlling the guide block 103 to reciprocate along the guide groove 102 with the lower cooling component 200. Then, the cooling water in the water storage tank 202 is drawn out by the high-pressure pump 203 and transported through the water supply pipe 204. It is then sprayed out through the high-pressure nozzle 205. Finally, the water pressure is enhanced by the conical nozzle 206, which improves the cooling effect. The sprayed cooling water is sprayed onto the surface of the slope flange 208 to expand the cooling area. Some of the cooling water flows out through the drain hole 209 of the inclined structure to cool the laser nozzle 207. At the same time, the reciprocating motion of the cooling component 200 can perform synchronous cooling on the workpiece. Therefore, the cooling effect can be improved and the ease of use of the cooling device can be improved.
