Description

Technical Field

[0001] The present invention relates to the technical field of metal sheet processing, in particular to metal sheet processing equipment based on high-energy laser beams. Background Art

[0002] High-energy laser beams are high-energy-density laser beams generated by high-energy lasers, which are focused into linear beams through specific optical systems to process materials or achieve specific functions. The output power is usually in the megawatt to gigawatt level. When the beam is focused to a very small point, it has an extremely high energy density and can be used for micro-processing, cutting, punching and other processes. In the metal sheet cutting process, high-energy laser beams can quickly melt and vaporize the metal due to their high energy density and precise focusing, achieving high-precision, high-quality cutting.

[0003] In the current process of processing metal sheets using high-energy laser beams, in order to prevent the metal sheets from shifting and affecting the processing accuracy, the industry generally uses movable clamps to clamp and limit the edges of the metal sheets. Given the thin wall thickness of the metal sheets, this edge clamping method can easily cause them to deform slightly, ultimately adversely affecting the processing accuracy of the metal sheets. Summary of the Invention

[0004] The present invention relates to metal sheet processing equipment based on high-energy laser beams. The movable slide can be moved and adjusted according to the different specifications of the metal sheet to be processed, and the distance between the two electromagnets can be changed. When the metal sheet is placed on the top of the serrated strip, the electromagnet is brought into adsorption contact with the bottom side of the metal sheet, and the metal sheet is magnetically fixed, thereby ensuring the stability of the metal sheet in the laser cutting state, thereby ensuring the processing accuracy of the metal sheet.

[0005] In a first aspect, the present invention provides a metal sheet processing device based on a high-energy laser beam, which specifically includes: a processing platform, a movable scraper, a screw, a support rail seat, a movable slide seat, an electromagnet, a support frame, a metal sleeve, a coil, a positioning pin, a transmission sprocket and a chain; the top of the processing platform is provided with serrated strips in an arranged manner, and the top of the processing platform is connected to the movable scraper; the inside of the processing platform is connected to a screw, the end of the screw is provided with a handwheel, and the screw is connected to the movable scraper; the top of the processing platform is fixedly installed with a support rail seat, and the support rail seat Two movable slides are connected to the top, and an electromagnet is embedded in the top of the movable slide, and the top of the electromagnet is flush with the top of the serrated plate; a support frame is fixedly installed on the bottom of the movable slide, and a metal sleeve is connected to the bottom of the support frame, and a metal sleeve is connected to the outside of the metal sleeve; two positioning pins are connected to the bottom of the movable slide, one end of the positioning pin is connected to the metal sleeve, and the other end of the positioning pin is connected to the support rail seat; four transmission sprockets are connected to the inside of the support rail seat, and a chain is connected to the outside of the transmission sprocket, and both ends of the chain are connected to the bottom of the movable slide.

[0006] Furthermore, the movable slide is slidably connected to the support rail seat, and rollers are symmetrically arranged inside the movable slide. The rollers are in rolling contact with the support rail seat. The movable slide can be moved and adjusted according to the different specifications of the metal sheet to be processed, and the distance between the two electromagnets can be changed. When the metal sheet is placed on the top of the serrated strip, the electromagnet is adsorbed and contacted with the bottom side of the metal sheet, and the metal sheet is magnetically fixed.

[0007] Furthermore, guide holes are symmetrically provided on the bottom of the movable slide seat, and positioning holes are equidistantly provided on both sides of the support rail seat, and the guide holes are alternately connected with the positioning holes provided on the support rail seat.

[0008] Furthermore, the positioning pin slides through a guide hole provided in the movable slide seat, and the outer end of the positioning pin is inserted into the positioning hole.

[0009] Furthermore, the coil is wound around the outside of the metal sleeve, the two ends of the metal sleeve are connected, and the inner end of the positioning pin is slidably connected to the metal sleeve.

[0010] Furthermore, a plastic spring is placed in the metal sleeve, one end of the plastic spring contacts the inner end of one of the positioning pins, and the other end of the plastic spring contacts the inner end of the other positioning pin. After the movable slide is adjusted to the desired position, the guide hole and the positioning hole are connected, the coil is powered off, the magnetic attraction of the metal sleeve disappears, and the positioning pin moves outward under the influence of the thrust of the plastic spring, so that the outer end of the positioning pin is inserted into the positioning hole, thereby locking the movable slide.

[0011] Furthermore, the transmission sprocket is rotatably connected to the support rail seat, and the transmission sprocket is connected to another chain through a chain. Gears are provided at both ends of the transmission sprocket, and the gears are engaged with the gears provided on the other transmission sprocket. When one of the movable slides is moved, the movable slide drives the transmission sprocket to rotate through the chain, and the two gears are engaged with each other. The transmission sprocket drives the other movable slide to move synchronously through the chain, thereby realizing the synchronous inward or outward movement adjustment of the two movable slides.

[0012] Furthermore, the movable scraper is slidably connected to the processing platform, the two sides of the top of the movable scraper are inclined, and through grooves are equidistantly arranged inside the movable scraper, and the serrated strips are slidably connected to the through grooves provided in the movable scraper.

[0013] Furthermore, the screw is rotatably connected to the processing platform, and a threaded hole is provided at the bottom of the movable scraper. The screw is threadedly connected to the threaded hole provided in the movable scraper. After the laser cutting process of the metal sheet is completed, the screw is rotated, and the screw drives the movable scraper to move back and forth in sequence, and the slag attached to the serrated plate is scraped off by the movable scraper.

[0014] The present invention provides a metal sheet processing device based on a high-energy laser beam, which has the following beneficial effects: When the present invention is in use, in order to adapt to the processing requirements of metal sheets of different specifications, the movable slide can be moved and adjusted to accurately change the spacing distance between the two electromagnets; when the metal sheet is placed on the top of the serrated plate, the electromagnet is adjusted to be in close adsorption contact with the bottom side of the metal sheet, and the metal sheet is firmly fixed with the help of a strong magnetic attraction force; it can effectively ensure that the metal sheet is always in a stable state during the laser cutting process, thereby providing reliable guarantee for the high-precision processing of the metal sheet.

[0015] In addition, when the movable slide is adjusted to the required position, the guide hole and the positioning hole are connected. At this time, the power supply of the coil is cut off, and the magnetic attraction of the metal sleeve disappears. Under the thrust of the plastic spring, the positioning pin moves outward, and its outer end is accurately inserted into the positioning hole, thereby completing the locking of the movable slide and ensuring the stability of the electromagnet position; and when the position of the movable slide needs to be adjusted, it is only necessary to energize the coil, and the metal sleeve will generate a magnetic attraction. Under the action of this magnetic attraction, the positioning pin moves inward, and at the same time, the two ends of the plastic spring contract inward, causing the outer end of the positioning pin to detach from the positioning hole, and the locking state of the movable slide is released. Then, the movable slide can be flexibly and adaptively adjusted.

[0016] In addition, when a moving force is applied to one of the movable slides, the movable slide will rotate with the help of a chain driving the transmission sprocket connected to it. Through the precise transmission engagement mechanism between the two gears, the transmission sprocket further drives the other movable slide to move synchronously through the chain, thereby realizing the adjustment function of the two movable slides to shrink inward or expand outward synchronously, effectively ensuring the high synchronization of the two movable slides in the process of moving and adjusting in the inward and outward directions.

[0017] In addition, after the laser cutting process of the metal sheet is completed, the operator only needs to turn the screw to drive the movable scraper to move back and forth. During the movement, the movable scraper will completely scrape off the slag attached to the serrated plate in turn, effectively preventing the slag from excessive accumulation and thickening. It can continuously ensure the cleanliness of the serrated plate and avoid the tedious operation of shutting down due to excessive accumulation of slag and spending a lot of time using tools for cleaning.

[0018] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
