[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs; the terms used herein and / or include any and all combinations of one or more related listed items.

[0044] like Figures 1 to 8 As shown, the gas spring sleeve laser cutting feeding device 200 of this embodiment is placed at the feeding end of the laser cutting equipment 100, and can transport the steel pipe 300 to the laser cutting equipment 100, including: a frame 210; a steel pipe storage component 220 placed on one side of the frame 210; a steel pipe bearing component 230 connected to the steel pipe storage component 220; a propulsion component 240 placed at the tail of the steel pipe bearing component 230; and a lifting component 250 placed under the steel pipe storage component 220; the steel pipe bearing component 230, the propulsion component 240 and the lifting component 250 are all arranged on the frame 210.

[0045] For the specific structure of the laser cutting equipment 100 adopted in the present invention, please refer to the content disclosed in patent CN202410161988.3. The steel pipe is transported into the laser cutting equipment from one side and then subjected to rotary laser cutting.

[0046] The device realizes an integrated structure of storing and feeding the steel pipe 300, and uses the propulsion component 240 to transport the steel pipe 300 to the laser cutting equipment 100. The laser cutting equipment 100 cuts a section, and the propulsion component 240 propels it forward a section, which effectively improves the working efficiency of the entire production line.

[0047] In this embodiment, in order to facilitate the matching of the height of the frame 210 with the height of the laser cutting device 100, a height adjustment bolt 211 is provided at the lower end of the frame 210, and the matching height is adjusted by the height adjustment bolt 211.

[0048] Combination Figure 3 As shown, the number of the steel pipe storage components 220 is at least two groups, and the steel pipe storage components 220 include a support frame 221, an inclined rod 222 arranged on the support frame 221, a stop protrusion 223 arranged at the bottom of the inclined rod 222 for stopping the steel pipe 300, and a rolling platform 224 connected to the upper end surface of the stop protrusion 223, the inclined rod 222 has an inclination angle of 45°; the stop protrusion 223 has an arc-shaped surface 2231 on the side close to the inclined rod 222, so as to facilitate the rolling of the steel pipe 300, and the rolling platform 224 has a certain inclination angle and extends to the top of the steel pipe bearing component 230, and the inclination angle is 3-5°, preferably 3°.

[0049] Further, such as Figure 5 and Figure 7 As shown, the steel pipe bearing component 230 includes a base 231, a bracket 232 and two rollers 233. The base 231 is fixed on the frame 210. The bracket 232 is V-shaped and is hinged to the base 231 through a pin. The bracket 232 can rotate around the pin. The two rollers 233 are respectively arranged at both ends of the bracket 232. The two rollers 233 form a supporting surface for the steel pipe 300. With such a structural design, on the one hand, the steel pipe enters the laser cutting equipment 100 and needs to be rotated for cutting. The rollers 233 can effectively reduce friction and rotate smoothly. On the other hand, the V-shaped bracket can rotate, which is beneficial to buffer the impact force generated when the steel pipe 300 falls, thereby extending the service life of the steel pipe bearing component 230.

[0050] exist Figure 1 , Figure 3 and Figure 8In the figure, the propulsion component 240 includes two guide rails 241, a rack 242 disposed between the two guide rails 241, a mobile base 243 disposed on the guide rails 241, and a fixed plate 244 and a movable plate 245 disposed on the mobile base 243. The rack 242 is arranged in a vertical direction. The movable plate 245 is driven by a hydraulic cylinder to move relative to the mobile base 243. The hydraulic cylinder is fixed on the mobile base 243. A steel pipe 300 is sandwiched between the fixed plate 244 and the movable plate 245. The mobile base 243 reciprocates along the guide rails 241 through the meshing of a servo motor (not marked in the figure), a gear (not marked in the figure) and the rack 242, thereby pushing the steel pipe 300 forward. Further, the structure of the guide rails, servo motors, gears and racks is a commercially available linear guide structure, the mobile base 243 is a slider, and the servo motor drives the gear to mesh with the rack to reciprocate.

[0051] In order to increase the friction between the steel pipe 300 and the propulsion component 240 , the fixed plate 244 and the movable plate 245 are both provided with a V-shaped positioning groove 246 .

[0052] Combination Figure 4 and Figure 6 As shown, the lifting component 250 includes at least two lifting cylinders 251, which are located below the bottom of the inclined rod 222 and fixed on the support frame 221. The two lifting cylinders 251 can lift the steel pipe 300 and drive the steel pipe 300 to roll along the rolling platform 224 steel pipe bearing component 230. The lifting cylinders 251 need to push the steel pipe upward and make its lowest surface higher than the highest point of the stop protrusion 223.

[0053] The device of the utility model adopts PLC control and the PLC controller is shared with the laser cutting equipment 100, so the above-mentioned servo motor, servo motor, and hydraulic cylinder are all electrically connected to the PLC controller. When in use, the propulsion component 240 is first pushed to the rear end (to prevent the steel pipe 300 from being interfered by the fixed plate 244), and then the lifting cylinder 251 is actuated to lift the steel pipe 300, and the steel pipe 300 rolls along the rolling platform 224 to the steel pipe bearing component 230, and the signal sensor (electrically connected to the PLC control) arranged on one side of the roller 233 detects the steel pipe 300 and feeds back the signal to the PLC controller, and then controls the propulsion component 240 (the servo motor drives the gear to mesh with the rack 242) to move toward the steel pipe 300, and the spacing between the fixed plate 244 and the movable plate 245 is greater than the diameter of the steel pipe 300. When the propulsion component 240 moves to the set position, it stops moving and drives the movable plate 245 to clamp the steel pipe 300, and finally feeds the material to the laser cutting equipment 100.

[0054] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
