Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically to a laser cutting stage. Background Technology

[0002] Laser cutting is a non-contact thermal processing technology that uses a high-power-density laser beam to focus and irradiate the surface of a workpiece, causing the material to melt, vaporize, ablate, or reach its ignition point rapidly. The molten or vaporized material is then blown away by a high-speed auxiliary airflow coaxial with the laser beam, thereby achieving precise cutting of the material.

[0003] A laser cutting stage, also known as a laser cutting worktable or platform, is a movable or fixed platform structure in laser cutting equipment used to support, fix, and position the materials to be processed.

[0004] However, when aluminum alloy, stainless steel and copper alloy plates are placed on a laser cutting stage for laser cutting, the cut parts may be fixed to the parent plate by the residual material generated during the cutting process, which requires manual separation later. This process is quite cumbersome. Therefore, it does not meet the existing needs. To address this, we have proposed a laser cutting stage. Utility Model Content

[0005] The purpose of this utility model is to provide a laser cutting stage to solve the problems mentioned in the background art, such as when aluminum alloy, stainless steel and copper alloy plates are placed on the laser cutting stage for laser cutting, the cut parts may be fixed to the parent plate by the residual material generated during the cutting process, which leads to the need for manual separation afterward, and the operation is relatively cumbersome.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The cutting material collection box 2 (model 20243), transmission roller 6 (model PUMR638-3C1L4M3), and unloading cylinder 7 (model SC-32) mentioned in this utility model can all be obtained from the market or through private customization.

[0022] Please see Figures 1 to 4 An embodiment of this utility model is provided: a laser cutting stage, including a laser cutting stage body 1, a cutting material collection box 2 is slidably installed at the middle position of the front end face of the laser cutting stage body 1, and a strip-shaped outer shell 13 is provided on both sides above the cutting material collection box 2. A positioning cylinder 4 is fixedly installed on one side inside the strip-shaped outer shell 13. The piston rod of the positioning cylinder 4 is connected to a positioning side fixing plate 5. Multiple transmission rollers 6 are fixedly installed on the opposite surfaces of the two positioning side fixing plates 5.

[0023] A concave shell 3 is fixed to the upper end face of the two strip shells 13. A discharge cylinder 7 is fixedly installed on both sides inside the concave shell 3. The piston rods of the two discharge cylinders 7 are connected to a strip plate 8. The inside of the strip plate 8 is provided with multiple spring grooves 9. The inside of the spring grooves 9 contains springs 10. The lower end face of the spring 10 is connected to an anti-disengagement sleeve 11. The shaft of the anti-disengagement sleeve 11 is connected to a discharge push rod 12.

[0024] The rear end face of the laser cutting stage body 1 is provided with a strip-shaped mounting groove. Multiple conveying rollers 14 are installed inside the strip-shaped mounting groove, and the cross-sectional shape of the conveying rollers 14 is consistent with the cross-sectional shape of the transmission rollers 6. When the equipment is needed, the mother plate to be cut is placed on the upper end face of the conveying rollers 14, and then moved to the laser cutting area by the conveying rollers 14, and the forming part is cut out on its outer surface by the laser cutting mechanism.

[0025] After the cutting of the mother plate is completed, the positioning cylinder 4 pushes the positioning side fixing plate 5 connected to it. At this time, the distance between the two positioning side fixing plates 5 is adjusted according to the size of the mother plate. After the distance between the two positioning side fixing plates 5 is adjusted, the cutting mother plate is moved between the two positioning side fixing plates 5 by the conveying roller 14. During the process of the mother plate moving between the two positioning side fixing plates 5, the upper end face of the transmission roller 6 installed on the outer surface of the positioning side fixing plate 5 will fit against the lower end face of the mother plate to support it.

[0026] During the process of the mother plate moving between the two positioning side fixing plates 5, the molded parts cut out from its outer surface that are not fixed due to the leftover material will fall directly into the interior of the cutting material collection box 2 under the action of gravity.

[0027] After the mother plate is completely moved between the two positioning side fixing plates 5, the strip plate 8 is pushed down by the two unloading cylinders 7. As the strip plate 8 descends, the multiple unloading push rods 12 located on its lower end face will also descend. As the multiple unloading push rods 12 descend, when the unloading push rod 12 located above the molded part on the outer surface of the mother plate contacts the molded part, it will apply downward pressure to it. This downward pressure can push down the molded part that is fixed on the mother plate due to the excess material. Through the above technical solution, the mother plate and the cut molded part can be automatically separated, thereby improving the automation level of the equipment and increasing its convenience.

[0028] When the unloading push rod 12 located above the mother plate comes into contact with the mother plate, as the strip plate 8 descends, the unloading push rod 12 that is in contact with the mother plate will stay in its current position and compress the spring 10 that is indirectly connected to it. This structure can prevent the strip plate 8 connected to the unloading push rod 12 from getting stuck and unable to continue pushing the strip plate 8 downward because some unloading push rods 12 directly contact the mother plate.

[0029] After all the molded parts on the mother plate are removed, the mother plate is moved forward by the transmission roller 6 to eject it from the laser cutting stage body 1.

[0030] The cutting material collection box 2 has a universal pulley fixed at each of the four corners of its lower end face, and the cutting material collection box 2 is fixed to the universal pulley by screws; however, when it is necessary to process the molded part located inside the cutting material collection box 2, simply pull the cutting material collection box 2 forward and move it to the next processing position by means of the universal pulley fixed to its lower end face.

[0031] The upper end face of the positioning side fixing plate 5 is higher than the upper end face of the conveying roller 14. A balance guide rod is fixedly provided on both sides of the front end face of the first positioning side fixing plate 5 and both sides of the rear end face of the second positioning side fixing plate 5 from left to right. The balance guide rod is movably inserted into the interior of the strip-shaped outer shell 13. The balance guide rod can ensure the parallelism of the positioning side fixing plate 5 and prevent it from bending.

[0032] The lower end face of the unloading push rod 12 is an arc-shaped head 15, and the unloading push rod 12 is made of plastic in one piece. By using plastic to make the unloading push rod 12 and its lower end face is an arc-shaped head 15, the unloading push rod 12 can prevent impact damage to the molded part.

[0033] The unloading cylinder 7 is provided with a protective cover plate located on the upper end face of the concave outer shell 3, and the concave outer shell 3 and the protective cover plate are fixed together by screws; the protective cover plate can protect the internal structure of the concave outer shell 3, and when the internal structure of the concave outer shell 3 fails, the protective cover plate can be removed to repair the internal structure of the concave outer shell 3.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
