Description

Technical Field

[0001] The present invention relates to the technical field of laser micro-processing, in particular to an ultrasonic-assisted water jet laser processing system. Background Art

[0002] In the field of laser micro-processing of high aspect ratio cavities of cemented carbide special-shaped wire drawing dies, the existing processing processes still have many technical bottlenecks, which are difficult to meet the requirements of high-precision, high-efficiency mass production.

[0003] At present, conventional laser processing equipment mostly adopts a single-station operation mode, in which workpiece processing and residue cleaning procedures are separated from each other, and the overall operation adopts a serial operation mode. After the workpiece completes laser processing, it is necessary to stop the machine to wait for manual residue cleaning or rely on the equipment to stand for natural slag discharge, resulting in a long waiting time between procedures, which greatly reduces the overall processing efficiency and cannot realize continuous automated mass processing.

[0004] For special-shaped cavities with deep and narrow structures, molten slag generated during laser processing is very easy to adhere to the inner wall of the cavity and cool and solidify rapidly, forming solid residues firmly attached and a thick recast layer. Relying only on the conventional water jet scouring method equipped for laser processing, it is difficult to completely remove the solidified impurities inside the cavity, which easily causes rough inner wall of the cavity and deviation in dimensional accuracy, seriously affecting the molding quality and service performance of the wire drawing die.

[0005] Meanwhile, the existing processing equipment lacks an autonomously linked sewage purification and chip cleaning structure, and the chip-containing sewage generated by processing cannot be automatically circulated and purified. Processing chips accumulate inside the equipment cavity for a long time, which easily causes problems such as impurity accumulation and water channel blockage. Not only is it difficult to guarantee the cleanliness of the equipment and the frequency of daily maintenance is high, but also the automation and integration level of the overall equipment can hardly meet the production requirements of modern precision processing.

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 11 As shown, this embodiment provides an ultrasonic-assisted waterjet laser processing system, including a clamping mechanism 10, a cleaning mechanism 20, a purification mechanism 30, a fiber laser 40, and a high-pressure water nozzle 50. The clamping mechanism 10 includes a mounting box 101, a mounting plate 102, a servo motor 105, and two sets of clamps. The mounting plate 102 is rotatably supported on the mounting box 101, and the two sets of clamps are symmetrically arranged on the mounting plate 102. The servo motor 105 is used to drive the mounting plate 102 and the two sets of clamps to rotate synchronously by 180° to achieve workstation switching. One clamp rotates to the top to clamp the parts to be laser-processed, and the other clamp rotates to the bottom to clamp the parts to be ultrasonically cleaned. The cleaning mechanism 20 is located below the clamping mechanism 10 and includes an ultrasonic transducer 202, a cam assembly, and a pair of scraping plates 208. The servo motor 105 transmits power through the cam assembly to drive the ultrasonic transducer 202 to approach the part to be cleaned below to perform ultrasonic cleaning. At the same time, it drives the pair of scraping plates 208 to reciprocate in the horizontal direction to scrape and collect the processing debris accumulated at the bottom of the mounting box 101. The purification mechanism 30 is located below the cleaning mechanism 20 and includes a piston assembly, a water collection tray 307, a perforated plate 309, and filter cotton 310. The filter cotton 310 is laid flat on the perforated plate 309, and the perforated plate 309 is installed horizontally inside the water collection tray 307. The cam assembly is driven by the piston assembly to drive the piston assembly to discharge the sewage containing debris from the installation box 101. After being filtered and purified by the filter cotton 310, the sewage drips through the perforated plate 309 and is temporarily stored in the water collection tray 307. The fiber laser 40 is positioned above the clamping mechanism 10 and is used to perform laser processing on the parts at the upper workstation. The high-pressure water nozzle 50 is arranged adjacent to the fiber laser 40 and is used to spray high-pressure water jets to assist the laser processing. In this embodiment, a pair of mounting shafts 103 are coaxially fixed at both ends of the mounting plate 102. Each mounting shaft 103 is rotatably mounted on the mounting box 101 via a deep groove ball bearing 104. The servo motor 105 is fixed to the rear side of the mounting box 101 via a motor mount 106, and its output shaft is coaxially connected to the rear mounting shaft 103 via a coupling 107. The mounting shaft 103 and the deep groove ball bearing 104 cooperate to achieve smooth rotational support of the mounting plate 102 and reduce rotational friction resistance. The coupling 107 realizes coaxial transmission between the servo motor 105 and the mounting shaft 103, ensuring the positioning accuracy and motion stability of the rotary workstation switching and avoiding workpiece alignment deviation caused by rotational offset.

[0032] In this embodiment, the side of the mounting plate 102 is provided with a guide rail 108, and a slider 109 is slidably fitted on the guide rail 108. A slide plate 110 is fixedly installed on the outer side of the slider 109. A clamping block 111 is fixedly installed at the front end of the slide plate 110, and a clamping block 112 is correspondingly installed at the front end of the mounting plate 102. A pair of dual-axis cylinders 113 are symmetrically installed on the left and right sides of the mounting box 101. The piston rods of the two dual-axis cylinders 113 are fixedly connected to a moving frame 114. A thrust ball bearing 115 is provided between the moving frame 114 and the rear ends of the two slide plates 110. The guide rail 108 and slider 109 enable precise sliding guidance of the slide plate 110. The dual-axis cylinder 113 drives the moving frame 114 to translate, and the thrust ball bearing 115 enables smooth thrust transmission. This drives the clamping block 111 and clamping block 212 to automatically clamp and position the workpiece. The clamping accuracy is high and the stability is good, which can effectively prevent the workpiece from shifting or deviating during laser processing and station switching.

[0033] Furthermore, a pair of return springs 116 are provided between clamping block 111 and clamping block 112. After the cylinder releases the force, the return springs 116 can drive clamping block 111 to automatically reset and release the workpiece, realize the quick assembly and disassembly of the workpiece, improve the loading and unloading efficiency, and at the same time buffer the clamping impact force to avoid rigid clamping damage to the surface of the precision workpiece.

[0034] In this embodiment, a lifting strip 201 is provided below the mounting plate 102, and the ultrasonic transducer 202 is located above the lifting strip 201. A support plate 203 is glued to the upper end of the ultrasonic transducer 202, and the support plate 203 is elastically supported on the lifting strip 201 by a pair of damping springs 204. A pair of hinge bars 205 symmetrically distributed in a figure-eight shape are respectively hinged to the front and rear ends of the lifting strip 201. A pair of scraping plates 208 are symmetrically arranged on the left and right, and the front and rear ends of each scraping plate 208 are respectively connected to the corresponding hinge bars 205. A cam 209 is fixedly installed on each mounting shaft 103, and the contour surface of the cam 209 abuts against the upper surface of the lifting strip 201. A support plate 210 is provided below the pair of scraping plates 208, and the support plate 210 is horizontally fixed to the lower cavity of the mounting box 101. The damping spring 204 provides elastic support for the ultrasonic transducer 202, which can buffer the vibration interference transmitted from the ultrasonic vibration to the whole machine structure and avoid the vibration affecting the laser processing accuracy above. The cam 209 rotates synchronously with the mounting shaft 103, precisely driving the lifting bar 201 to move up and down reciprocally. Together with the figure-eight hinge bar 205, it realizes the linkage between the lifting of the transducer and the horizontal sliding of the scraper plate 208. It is a multi-functional machine that simplifies the overall transmission structure and reduces the manufacturing cost of the equipment.

[0035] Furthermore, a connecting rod 206 is threaded between each pair of hinge bars 205, and a second return spring 207 is fitted on both sides of the connecting rod 206. The connecting rod 206 ensures the synchronous movement of the hinge bars 205 on both sides, and the second return spring 207 provides a return force for the hinge transmission structure, ensuring stable and reliable reciprocating sliding movement of the scraping plate 208, avoiding transmission jamming and incomplete movement, and improving the debris scraping effect.

[0036] In this embodiment, a row of piston cylinders 301 is fixedly installed between the support plate 210 and the bottom of the mounting box 101. A piston body 302 is slidably fitted inside each piston cylinder 301. A piston rod 303 passes through the center of each piston body 302, and the top end of the piston rod 303 is fixedly connected to the lifting bar 201. A pair of one-way valves 304 are symmetrically arranged on the lower left and right sides of each piston cylinder 301 to control the unidirectional flow of liquid into the piston cylinder 301. A pair of one-way valves 306 are symmetrically arranged on the lower left and right sides of each piston cylinder 301 to control the unidirectional discharge of liquid from the piston cylinder 301. The lifting bar 201's lifting movement synchronously drives the piston rod 303 and piston body 302 to reciprocate, forming an automatic suction and drainage structure with the one-way valves 304 and 306. This allows for automatic circulation and discharge of wastewater from the box without the need for an independent water pump. Fluid purification is achieved through the mechanical movement of the equipment itself, resulting in a high degree of structural integration and automation.

[0037] Furthermore, the water collection tray 307 is detachably connected to the lower side of the mounting box 101. The top of the water collection tray 307 has several evenly spaced positioning holes 307a, and the bottom of the mounting box 101 has several corresponding positioning pins 308 fixed thereon. Each positioning pin 308 is inserted into and engaged with one of the positioning holes 307a. Through the insertion and engagement of the positioning pins 308 with the positioning holes 307a, the water collection tray 307 can be quickly and accurately positioned and installed. Simultaneously, the detachable structure facilitates subsequent cleaning of impurities inside the water collection tray 307 and replacement of the filter cotton 310, significantly improving the convenience of equipment maintenance.

[0038] Furthermore, the angle between the fiber laser 40 and the high-pressure water nozzle 50 is 5°-15°. This small-angle off-axis arrangement of 5°-15° allows the high-pressure water jets to precisely converge at the laser processing focal area, avoiding water flow obstruction of the laser beam path and causing energy attenuation. It also enables all-round cooling and oblique flushing of slag in the processing area, meeting the requirements for slag removal without dead angles in high aspect ratio irregular cavities, and minimizing recast layer and thermal damage.

[0039] The working principle of an ultrasonic-assisted waterjet laser processing system is as follows: S1. Workpiece clamping preparation process Servo motor 105 drives mounting plate 102 to rotate, arranging the two sets of clamps vertically to the left and right. The operator places the two wire drawing dies 60 to be processed in the clamping positions on the left and right sides respectively. Subsequently, dual-axis cylinder 113 drives moving frame 114 to move horizontally. Moving frame 114 transmits thrust through thrust ball bearing 115, pushing slide plate 110 to slide along guide rail 108 and slider 109, causing clamping block one 111 to move closer to clamping block two 112, thus locking and fixing the wire drawing die 60. After clamping, servo motor 105 drives mounting plate 102 to rotate 90°, changing the two sets of clamps from a left-right arrangement to a vertically arranged horizontal distribution, completing the pre-processing workstation layout adjustment.

[0040] S2. Layered laser processing and station rotation process The fiber laser 40 at the upper station is activated to perform laser ablation processing. High-pressure water nozzles 50, positioned at a 5°-15° angle to the fiber laser 40, continuously spray off-axis high-pressure water jets to remove molten slag in real time, suppressing thermal damage and the formation of a recast layer. This process removes several processing layers from the forming cavity 602a of the upper wire drawing die 60 core 60. After completing the set number of processing layers, the servo motor 105 drives the mounting plate 102 to rotate 180°, completing a station interchange. The wire drawing die 60, which had previously completed multi-layer processing at the upper station, rotates to the lower cleaning station, while the wire drawing die 60, previously awaiting processing at the lower station, rotates to the upper processing station. The fiber laser 40 continues to perform layered laser processing on the newly switched upper wire drawing die 60, while the high-pressure water nozzles 50 simultaneously spray water jets to flush away the molten slag.

[0041] S3. Ultrasonic linkage cleaning, debris removal and wastewater filtration process The wire drawing die 60, rotated to the lower station, is immersed in the water inside the mounting box 101. During this time, the servo motor 105 drives the cam 209 to rotate, causing the lifting bar 201 to rise intermittently, bringing the ultrasonic transducer 202 closer to the wire drawing die 60 in the lower station. The ultrasonic transducer 202 is elastically buffered and supported by the support plate 203 and the damping spring 204, generating a cavitation effect in the water to peel off the solid slag and particulate debris attached to the inner wall of the forming cavity 602a. During the intermittent lifting and lowering of the lifting bar 201, the eight-shaped hinge bars 205 at both ends are driven to open and close intermittently, causing a pair of scraping plates 208 to move horizontally back and forth along the support plate 210, intermittently scraping and collecting the processing debris that has settled at the bottom of the mounting box 101. At the same time, the lifting bar 201 drives the piston rod 303 and the piston body 302 to slide intermittently up and down inside the piston cylinder 301. As piston 302 moves upward, wastewater carrying debris is drawn into piston cylinder 301 through one-way valve 304; as piston 302 moves downward, wastewater is discharged outward through one-way valve 306. The wastewater flows downward through filter cotton 310 above perforated plate 309 to complete solid-liquid separation. Metal debris is trapped by filter cotton 310, and the purified water is collected through perforated plate 309 into collection tray 307 for temporary storage.

[0042] S4. Cyclic processing steps The process involves continuous alternating workstation switching, upper-layer laser layering, and lower-layer ultrasonic cavitation cleaning, gradually completing the overall processing of the forming cavity 602a of the mold core 602. Once the forming cavities of both wire drawing dies 60 have met the dimensional requirements, the servo motor 105 drives the mounting plate 102 to rotate, causing the two sets of fixtures to be vertically distributed left and right. The dual-axis cylinder 113 then resets, and the reset spring 116 pushes the clamping block 111 to reset and release the workpiece. The operator then removes the finished wire drawing die 60 and enters the next processing cycle.

[0043] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
