Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a laser cutting device for high-temperature furnace processing. Background Art

[0002] High temperature furnace is a kind of experimental equipment widely used in the fields of materials science, metallurgy, chemical industry, etc. It is used to perform various heat treatment, sintering and other experimental operations on materials under high temperature environment. The main components of high temperature furnace include furnace body, furnace, heating element, insulation layer and control system, etc. The core part of high temperature furnace is usually composed of heating element, thermocouple and heating power supply. The heating element is the part that directly heats the experimental sample. The thermocouple is used to measure the temperature of the experimental area. The heating power supply provides electrical energy to the heating element. The high temperature furnace usually needs to rotate during use, which is mainly to ensure the uniformity of the temperature in the furnace and the accuracy of the experimental results. The rotation function of the high temperature furnace can achieve uniform temperature distribution in the following ways. Since the heating elements are mostly heating electric heating wires, during the rotation of the high temperature furnace, some large particles of materials will flip and collide with the heating elements, causing damage to the heating elements. It is necessary to set a sleeve furnace core to cover the outside of the heating element to prevent the heating element from being damaged. Since it is necessary to ensure the heating efficiency of the heating element, the sleeve furnace core needs to cut several holes on its surface during the processing process for heat energy transfer.

[0003] The prior art uses laser cutting to perform laser cutting on the surface of the furnace core. However, during the processing, when the laser cutting head performs laser cutting on the outer surface of the furnace core, the sparks will hit the inner wall of the furnace core, which is likely to damage the inner wall of the furnace core and cause processing defects on the inner wall. Secondly, during cutting, the cut waste will fall into the furnace core. During the rotation of the furnace core, the waste cannot be accurately aligned with the cut hole and is easily stuck in the cut hole. As a result, after the processing is completed, the waste in the furnace core needs to be manually cleaned, resulting in low processing efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a device that, when a laser cutter is used to open a hole on a furnace core, the cutting sparks are absorbed by the inner wall of the auxiliary welding tube, and the inner wall of the furnace core will not be damaged, thereby avoiding defects. Secondly, while achieving cutting protection, waste can be effectively collected, thereby improving processing convenience, avoiding secondary processing of waste after furnace core processing, and saving processing costs.

Material part 4, the auxiliary welding tube 22, when inserted into the furnace core, serves as a protective plate for the inner wall of the furnace core and also as a straw for collecting waste. The auxiliary welding tube 22 is inserted into the furnace core. When the laser cutter 3 makes a hole in the furnace core, its cutting sparks are absorbed by the inner wall of the auxiliary welding tube 22, and will not damage the inner wall of the furnace core, thereby avoiding defects. Secondly, when the laser cutter 3 cuts holes in the furnace core, the waste cut off falls into the auxiliary welding tube 22. The suction part 4 provides suction, and the waste is adsorbed and collected through the auxiliary welding tube 22 while cutting, thereby achieving effective waste collection while realizing cutting protection, improving processing convenience, avoiding secondary processing of waste after furnace core processing, and saving processing costs.

[0031] The clamp 21 includes a round seat 211 for fixing, one end of the round seat 211 is connected to a clamping ring 212, the clamping ring 212 is provided with three mounting grooves 213, and each mounting groove 213 is provided with an L-shaped pawl 214, the pawl 214 is connected to the inner wall of the mounting groove 213 through a shaft, and the pawl 214 can rotate around the shaft in the mounting groove 213, a moving seat 215 is provided in the round seat 211, and an inner groove for the moving seat 215 to move is provided in the round seat 211, and an annular groove 2151 is provided on the outer surface of the moving seat 215, and a clamping block 2141 is provided at one end of the pawl 214, and the clamping block 2141 The plug-in arrangement is in the annular groove 2151, and the movable seat 215 is connected to the driver.

The collecting pipe 42 is connected to the collecting box 421 through a feeding pipe. A filter screen plate 422 is arranged on the inner wall of the collecting pipe 42 close to one end of the suction air pump 41. The suction air pump 41 provides suction. The collecting pipe 42 and the auxiliary welding pipe 22 serve as suction pipes to immediately absorb the waste and cutting waste that have just been cut and dropped into the collecting pipe 42.

[0033] Example 2: Reference Figure 6 - Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the clamp 21 also includes four fixed claw blocks 216, a rotating main disk 217 and a driving cylinder 218. The rotating main disk 217 is provided with a slide groove 2171 for moving the four fixed claw blocks 216. A square disk 2172 is installed on the upper end of the rotating main disk 217 through a bearing. The four fixed claw blocks 216 are respectively connected to the four corners of the square disk 2172 through a bent rod 2161. The two ends of the bent rod 2161 are respectively hinged to the fixed claw blocks 216 and the square disk 2172. A driving cylinder 218 is installed below the rotating main disk 217. The two ends of the driving cylinder 218 are respectively connected to the opposite The two fixed claw blocks 216 are connected, and the driving cylinder 218 is extended and retracted to drive the two symmetrical fixed claw blocks 216 to move toward or oppositely. When the driving cylinder 218 retracts, it drives the two fixed claw blocks 216 to move toward each other. When the two fixed claw blocks 216 move, the square plate 2172 is driven to rotate through the bent rod 2161. When the square plate 2172 rotates, the other two fixed claw blocks 216 are driven to move toward each other through the bent rod 2161, thereby clamping the outer end surface of the furnace core. By setting the moving mode for clamping, it can meet the needs of clamping large-sized furnace cores and small-sized furnace cores, thereby improving the adaptability of the clamping fixture 21.

[0034] Example 3: Reference Figure 8, which is the third embodiment of the present invention. This embodiment is different from the first embodiment in that a number of auxiliary welding tubes 22 are provided. Only six are shown in the figure of this embodiment, and the annular array is arranged on the adjustment disk 6. The size of each auxiliary welding tube 22 is not the same, which is used to adapt to furnace cores of various sizes for insertion. A mounting plate is provided at one end of the adjustment disk 6, and a motor for driving the adjustment disk 6 to rotate is fixed on the mounting plate. A slot hole aligned with the collection tube 42 is opened on the adjustment disk 6. It should be noted that since each auxiliary welding tube 22 has a different size, it is impossible to match the nozzle of the collection tube 42. In this embodiment, the slot hole is trumpet-shaped, and the trumpet-shaped slot hole is used for the auxiliary welding tubes 22 of different sizes to align with the collection tube 42, so as to realize the conduction of the adsorption channel and facilitate the collection of waste. By rotating the adjustment disk 6, the auxiliary welding tubes 22 of different sizes can be aligned with the furnace core, thereby increasing adaptability.

[0035] It should be noted that during the laser cutting process, when the cutting lens is dirty, the cutting quality will be reduced. The dirty lens will cause the focusing effect of the laser beam to deteriorate, the cutting section effect to be inconsistent, the slag to increase, and even the problem of continuous cutting. The dirty lens will increase the absorption rate of the laser, causing the temperature to rise, resulting in a thermal lens effect, causing the focus of the cutting head to drift, and affecting the cutting accuracy. In order to solve the above problems, the present invention provides embodiment 4.

[0036] Example 4: Reference Fig. 9 - Fig.10 , which is the fourth embodiment of the present invention. This embodiment is different from the first embodiment in that the laser cutter 3 includes a cutting piece 31, a telescopic driver 32, a docking plate 33 and a total driving cylinder 34. The telescopic driver 32 drives the cutting piece 31 to extend and retract independently, and the total driving cylinder 34 drives the cutting piece 31, the telescopic driver 32 and the docking plate 33 to extend and retract together. A cleaning component 5 is installed on the laser cutter 3. When the laser cutter 3 is reset, the cleaning component 5 can clean the cutting mirror surface of the laser cutter 3. The cleaning component 5 includes a cleaning plate 51 that is movably fitted with the cutting mirror surface of the laser cutter 3. The upper end surface of the cleaning plate 51 is provided with a cleaning surface 511 that is fitted with the cutting mirror surface. Both sides of the cleaning plate 51 A fixing plate 512 is vertically installed, and a mounting rod 513 is vertically installed between the two fixing plates 512. An axis plate 52 is installed on the fixing plate 512 at one end, and the other end of the axis plate 52 is hinged to the lower end extension plate of the docking plate 33, as well as a push rod 53 hinged to the cutting piece 31 at one end, and the other end of the push rod 53 is axially connected to the mounting rod 513. When the cleaning plate 51 fits the cutting mirror surface of the laser cutter 3, the cleaning surface 511 fits the cutting mirror surface of the laser cutter 3 for cleaning. By setting the cleaning plate 51 to clean the cutting mirror surface of the laser cutter 3, the focusing effect of the laser beam is avoided to be poor, and the problem of continuous cutting is avoided, and the cutting accuracy is improved. The cleaning plate 51 is automatically reset to achieve automatic cleaning while moving upward.

[0037] Specifically, while the cutting piece 31 moves downward for cutting, the cleaning plate 51 is pushed to move by the push rod 53, so that the cleaning plate 51 is tilted and does not contact the cutting mirror surface of the laser cutter 3. When the cutting piece 31 moves upward to reset, the cleaning plate 51 is driven to reset by the push rod 53, and the cutting mirror surface of the laser cutter 3 is cleaned by the cleaning plate 51.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
