Description

Technical Field

[0001] This invention relates to the field of laser processing technology, specifically to a laser cutting device for processing mechanical parts. Background Technology

[0002] Under the overall trend of "lightweight, high strength, and short cycle" in the automotive industry, key parts such as body structural components, chassis brackets, and battery pack housings are generally made of 1-6mm high-strength steel, aluminum alloy, or multi-layer sheet metal. Their planar outlines are complex and the cut quality requirements are extremely high. Traditional stamping-blanking processes are difficult to meet the needs of multi-variety, small-batch production due to long mold cycles and poor flexibility. While CNC machining centers have high precision, they face bottlenecks such as low efficiency in large-format sheet metal processing and large clamping deformation. Laser cutting, with its non-contact, high energy density, and five-axis linkage capabilities, can complete one-time precision cutting of irregular holes, contours, and bevels on a single machine, and has become the mainstream solution for processing sheet metal in automotive parts.

[0003] Existing laser cutting equipment generally supports the sheet metal using a serrated worktable. This worktable typically consists of several parallel serrated steel bars. Relying on the point-to-surface contact between the tooth tips and the sheet metal, it can quickly remove slag, reduce slag buildup on the back, and facilitate automatic loading and unloading by forklifts or robotic arms. It is currently the most economical, universal, and efficient support solution for laser cutting equipment. However, after prolonged use, molten slag easily and firmly adheres to the tooth tips and grooves, forming hard nodules. These nodules scratch the bottom of the sheet metal and raise local support points, leading to unpredictable cutting errors in subsequent parts. Due to the structural limitations of the serrated worktable, the current cleaning method generally involves manual slag removal using tools on the worktable, which is time-consuming and costly. The laser beam can easily cut the tips of the serrated steel bars when the layout is dense or the bars are closely spaced, causing local gaps, dulling, or even breakage of the support teeth. If not replaced, the support effect will be affected. If replaced, the entire rack is a continuous structure, requiring complete disassembly and replacement, resulting in significant material waste and downtime for leveling, which further affects processing efficiency. Moreover, the high temperature of the laser is rapidly transmitted along the longitudinal direction of the rack, causing the metal to expand and contract in cycles, which can easily cause plastic warping of the entire rack and gradual deformation of the support flatness, further affecting the support effect on the sheet metal. This will exacerbate the vibration of the sheet metal during cutting and reduce the processing accuracy of the mechanical parts. Therefore, in view of the above problems, a laser cutting equipment for processing mechanical parts is proposed. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. In this invention, the structure of the cleaning module, worktable, single-tooth insert, and replacement module enables the worktable and single-tooth insert to be used as supports for the sheet metal. When the single-tooth insert needs cleaning, the obstruction to the single-tooth insert on the worktable can be removed by moving the drive unit and the ventilation baffle of the cleaning module upward. At this time, the replacement module can add a spare single-tooth insert to the worktable, while the single-tooth insert to be cleaned on the original worktable will be pushed into the cleaning module for cleaning. This realizes that when the support structure of the laser cutting equipment needs cleaning, a new support structure can be automatically replaced and the old support structure to be cleaned can be automatically cleaned, reducing the impact of support cleaning operations on laser processing efficiency. It solves the problem that the traditional cleaning of the support structure of laser cutting equipment requires manual operation, which is inconvenient, time-consuming, and affects the processing efficiency of the equipment.

[0016] 2. In this invention, the structure including the replacement module, worktable, and single-tooth inserts allows the airflow normally supplied by the replacement module to push and press the single-tooth inserts forward, ensuring a tight fit between them. Simultaneously, it removes the high temperature generated by laser processing, thus cooling the inserts. When a single-tooth insert is damaged and needs replacement, the worker can directly remove it from the support beam, and the replacement module will automatically fill the gap. This allows for quick and efficient replacement of any damaged section without stopping the machine or disassembling the entire sawtooth support structure, ensuring the efficiency of laser processing. Furthermore, it provides continuous cooling to the support structure under normal conditions, preventing overheating and deformation due to laser heat. This solves the problems of traditional support structures requiring complete replacement upon breakage, which is wasteful and inconvenient, and the support structure's ability to deform due to laser heat, affecting its support performance.

This setting allows the airflow delivered by the replacement module 8 under normal conditions to push and press the single tooth insert 4 forward, keeping the single tooth inserts 4 tightly fitted together. On the other hand, it can remove the high temperature of the single tooth insert 4 caused by laser processing, thus completing the heat dissipation of the single tooth insert 4. When a single tooth insert 4 is damaged and needs to be replaced, the staff can directly remove it from the support beam 33, and the replacement module 8 will automatically replace the missing part.The ejection channel 822 is located behind the positioning air channel 34 and the guide rail 35. The positioning air channel 34 and the guide rail 35 are aligned front and back with the ejection channel 822. The inner wall of the ejection channel 822 is smoothly transitioned with the inner walls of the positioning air channel 34 and the guide rail 35. This arrangement allows the single-tooth insert 4 in the ejection channel 822 to move forward and smoothly fill the support beam 33. The heat-conducting locking plate 43 is a magnetically attracted metal leaf-shaped plate, and the tooth body 42 is a non-magnetically attracted metal tooth-shaped block. This arrangement allows the high magnetic rod 847 to only magnetically attract the heat-conducting locking plate 43. When the high magnetic rod 847 drives the single-tooth insert 4 to move upward, the single-tooth insert 4... It will become in an inverted position. Distance sensors 843 are all positioned directly above the loading slot 823. This arrangement allows the distance sensors 843 to determine whether the loading slot 823 is empty by detecting distance. The inner wall of the guide shell 841 and the inner wall of the loading slot 823 have a smooth transition. The distance between the left inner wall of the guide shell 841 and the left end face of the timing belt 846 is the same as the width of the loading slot 823. The width of the loading slot 823 is the same as the maximum width of the single-tooth insert 4. This arrangement allows the single-tooth insert 4 to smoothly enter the loading slot 823 under the guidance of the timing belt 846 and the guide shell 841.

[0048] Workflow: The laser cutting equipment performs mechanical parts processing and equipment maintenance on the sheet metal as follows: Note 1: All electrical appliances used in this application are externally powered. The electrical appliances of the cleaning module 5 are centrally controlled via control box 1 6, and the electrical appliances of the replacement module 8 and processing section 2 are centrally controlled via control box 2 9. Note 2: Workers must pre-install several spare single-tooth inserts 4 in each storage slot 826 of the replacement module 8. Note 3: The water inlet pipe 518 must be pre-connected to the external liquid filling pipe, and the external drainage pipe with a regulating valve must be pre-connected to the drainage pipe 519 for water filling and drainage. Processing Operation: Workers... The operator places the sheet material on the workbench 3, which is composed of multiple sets of saw teeth arranged closely together with several single-tooth inserts 4, to support the sheet material. Then, the operation of the processing unit 2 is controlled by the control box 29. The X-axis moving mechanism 21 adjusts the gantry 22, Y-axis moving mechanism 23, and laser processing component 24 for lateral displacement, while the Y-axis moving mechanism 23 adjusts the laser processing component 24 for forward and backward displacement. This position adjustment moves the laser processing component 24 above the area of ​​the sheet material to be processed. At this point, its own up-and-down adjustment mechanism, i.e., the electric push rod, controls its downward movement to perform laser processing on the sheet material. Cutting and processing: Through the above operations, mechanical parts can be processed from the sheet metal. Heat dissipation: Multiple sets of saw teeth, composed of multiple single-tooth inserts 4, support the sheet metal. When laser processing generates high-temperature heat, this heat is conducted to the teeth 42 of the single-tooth inserts 4 and then transferred to each heat-conducting locking plate 43 via the elastic heat-conducting plate 41. At this time, the air pump 85 is continuously operated by the control box 2 9. The air pump 85 delivers gas to each air inlet 824 through the diversion pipe 86. After entering the air inlet 824, the gas flows forward along the channel. During the airflow, the gas is cooled by the installation of various heat-conducting components within the loading slot 823, the unloading channel 822, and the positioning air channel 34. There is a single-tooth insert 4 (the installation of the single-tooth insert 4 in the adding slot 823 and the outlet channel 822 is detailed in the subsequent "Disassembly and Supplementary Operations"). Since the two sets of heat-conducting locking plates 43 on the lower side of the single-tooth insert 4 are staggered, this structure not only plays a certain role in obstructing the flow, but also does not affect the normal flow of air. The forward-flowing airflow has two functions: on the one hand, the airflow applies a continuous forward thrust to the single-tooth insert 4 through the heat-conducting locking plates 43. This thrust ensures that the teeth 42 of the closely arranged single-tooth insert 4 always remain in close contact, thereby ensuring the stability of the formed serrated strip, and thus ensuring the stability of the support for the plate.On the other hand, as the airflow passes through the loading slot 823, the unloading channel 822, and the positioning air channel 34, it flows between the heat-conducting locking plates 43, thereby carrying away the heat from the single-tooth insert 4. This heat-carrying airflow eventually passes through the vent baffle 532 and is discharged from the exhaust port 527 of the linkage cover 525. In this way, heat dissipation of the single-tooth insert 4 is achieved, ensuring that each single-tooth insert 4 is always kept within a reasonable temperature range, avoiding deformation due to excessive heat; Disassembly and replenishment operation: When the tooth body 42 of a single-tooth insert 4 is damaged during laser processing due to collision, ablation, or other accidents... When a component is damaged and needs to be replaced, the elastic heat-conducting plate 41, which exhibits elastic deformation under pressure, allows the operator to visually locate the damaged single-tooth insert 4. The operator then pinches the tooth 42 with their fingers and lifts it vertically. At this point, each heat-conducting locking piece 43 moves upward synchronously under the upward pulling force, applying concentrated pressure to the elastic heat-conducting plate 41, causing it to undergo controllable elastic deformation. During this deformation, the heat-conducting locking pieces 43, originally positioned on the left and right sides, are forced to converge towards each other. The overall outer dimension after convergence is smaller than the passage gap of the guide rail 35, allowing the operator to insert the entire single-tooth insert 4. Smoothly pull out along guide rail 35 to complete the disassembly of the damaged part; after the damaged single-tooth insert 4 is removed, the space it originally occupied immediately forms a gap. Once this gap appears, the forward-pushing airflow continuously ejected by the diversion pipe 86 immediately applies a forward thrust to the supplementary single-tooth insert 4 prepared in the loading slot 823 and the outlet channel 822, pushing the insert directly into the guide rail 35 and the positioning air channel 34 in the support beam 33, and sequentially squeezing all the intact single-tooth inserts 4 on its front side to move it forward as a whole until it completely fills the gap left after removal; as the single-tooth insert 4 in the loading slot 823 is pushed out, the loading slot... When a gap appears in 823, the distance sensor 843 installed on the upper side can detect the gap by measuring the distance and send the distance change signal to the control box 2 9 in the form of an electrical signal. The control box 2 9 then drives the motor 3 845 of the transmission unit 84 to start. The output shaft of the motor 3 845 drives the synchronous roller 844 to rotate counterclockwise. The synchronous belt 846 moves counterclockwise in a cyclical manner under the traction of the synchronous roller 844. The high magnetic bar 847 fixed in the synchronous belt 846 moves together with the belt. When the high magnetic bar 847 runs to the area close to the storage slot 826 (at this time, the position of the high magnetic bar 847 is as follows: Figure 26As shown, the metal heat-conducting locking plate 43 of the closest single-tooth plug-in 4 pre-installed in the storage slot 826 generates a magnetic attraction. As the high magnetic bar 847 continues to move upward, the attracted single-tooth plug-in 4 automatically turns into an inverted posture with the tooth body 42 facing down due to the center of gravity. When the high magnetic bar 847 drives the single-tooth plug-in 4 to rotate to the left side of the synchronous belt 846 and enter the guide cover 842, the tooth body 42 returns to the correct posture from the inverted posture. Through the guidance of the inclined surface inside the guide cover 842, the single-tooth plug-in 4 is guided and adjusted so that it is precisely aligned with the upper inlet of the guide shell 841. At this point, the adjusted single-tooth insert 4 is smoothly conveyed into the guide shell 841 via the synchronous belt 846, ultimately falling accurately into the loading slot 823 to complete the replacement. The distance sensor 843 then detects the insertion's position in the loading slot 823 again. After confirming the replacement is complete, it sends a positioning signal to control box 9, which immediately stops motor 845. This completes one full cycle of automatic replacement of the single-tooth insert 4. Through this rapid disassembly and automated replacement process, it is possible to allow workers to operate the machine without stopping the machine or disassembling the entire sawtooth support structure. It can quickly and efficiently replace any damaged parts, thus ensuring the processing efficiency of laser processing operations. It can also continuously dissipate heat from the support structure under normal conditions, ensuring that the support structure will not overheat and deform due to the high temperature of the laser. This solves the problems of traditional support structures requiring complete replacement upon breakage, which is wasteful and inconvenient, and the support structure being affected by overheating and deformation due to the high temperature of the laser, thus affecting the support effect. Cleaning operation: When the molten slag adhering to the surface of each single-tooth insert 4 after prolonged use affects the support and needs cleaning, the operator can use the handle frame 522 to drive the linkage rail frame. 521. The linkage cover 525 moves upward guided by the guide frame 516. During this upward movement, the pin plate 523, which moves simultaneously with the handle frame 522, is squeezed out of the lowest pin groove 517. The elastic pin plate 523, held in place by the spring 524, can then re-insert into the upper pin groove 517. This process sequentially inserts the pin plate 523 into each of the upper pin grooves 517 until it reaches the highest pin groove 517, thus positioning the upward-moving drive unit 52. The upward movement of the drive unit 52 simultaneously moves the vent baffle 53 and the material rack 54 upward. Figure 20As shown, the upward movement of the material rack 54 allows its receiving screen plate 542 to wrap around the lower part of the stirring rod frame 56, while the upward movement of the vent baffle 53 will no longer block the single-tooth inserts 4 to be cleaned on the support beam 33. Under the propulsion of the airflow and the replenishment operation, the single-tooth inserts 4 to be cleaned on the support beam 33 will pass through the cover 513 into the chamber 512 of the cleaning module 5, and then fall into the receiving screen plate 542, waiting for subsequent cleaning. At the same time, the replenishment module 8 will replenish each support beam 33 with spare single-tooth inserts 4, so that the workbench 3 and the newly replaced single-tooth inserts 4 can still serve as supports for the sheet metal, without affecting the laser processing component 24 of the processing unit 2 to process the mechanical parts of the sheet metal. When all the single-tooth inserts 4 to be cleaned have entered the cleaning module 5, and only the newly replaced single-tooth inserts 4 remain on the support beam 33, the operator can push down the vent baffle 53 to block the single-tooth inserts 4 on the support beam 33 again. Figure 21As shown, to prevent the newly replaced single-tooth insert 4 from entering the cleaning module 5, water can be added to the base shell 511 through the water inlet pipe 518 and the external liquid addition pipe until the water covers the stirring rod frame 56. At this time, the motor 55 can be controlled by the control box 6 to run. The output shaft of the motor 55 drives the stirring rod frame 56 to rotate, stirring and impacting each single-tooth insert 4 in the receiving screen plate 542 to clean it. The single-tooth insert 4 collide with each other during stirring and impact. The water buffer reduces the damage caused by the collision of the single-tooth insert 4, causing the slag adhering to its surface to fall off. The fallen slag will sink and pass through the receiving screen. The sieve holes of the sieve plate 542 fall into the guide groove 514. After a period of cleaning, the operator stops the motor 55 by controlling the control box 6. The cleaning is observed through the cover 513. If it is satisfactory, the water is drained through the drain pipe 519 and the external drain pipe. Then, the positioning of the entire drive unit 52 is canceled by moving the pin plate 523 out of the pin groove 517, and the drive unit 52 is reset downward. The reset of the drive unit 52 will also reset the material rack 54, so that the drive block 546 of the material rack 54 is inserted into the blade gap of the spiral blade 58. At this time, the operator can remove the discharge gate 59. The door rail opening 515 on the right side of the base shell 511 is opened. Then, the motor 57 is started through the control box 6. The output shaft of the motor 57 drives the spiral blade 58 to rotate. The rotation of the spiral blade 58 will discharge the waste residue in the guide groove 514 to the right and let it fall into the waste shell 74 for collection. On the other hand, it will drive the drive block 546, the rail block 544 and the push plate 545 to the right to push the cleaned single tooth insert 4 in the receiving screen plate 542 to the right and let it fall onto the guide plate 72. Guided by the guide plate 72, the cleaned single tooth insert 4 falls into the tooth recycling shell 75. The cleaning operation is completed through the above operations. Once the cleaning module 5 is reset, it can be used for the next cleaning cycle. The cleaned single-tooth insert 4 in the tooth recovery shell 75 can be placed into the storage slots 826 of the replacement module 8 as a spare single-tooth insert 4. This realizes that when the support structure of the laser cutting equipment needs to be cleaned, a new support structure can be automatically replaced and the old support structure to be cleaned can be automatically cleaned. This reduces the impact of support cleaning operations on laser processing efficiency and solves the problem that the traditional cleaning of the support structure of laser cutting equipment requires manual operation, which is inconvenient, time-consuming and affects the processing efficiency of the equipment.
