Description

Technical Field

It has become one of the main forms of large-span spatial structure with its novel and unique architectural shape and good stress-bearing characteristics. During the production process of the membrane structure carport, a laser shearing machine is required to cut and process the steel plates of the carport beams, columns and side beams. Laser cutting replaces the traditional mechanical knife with an invisible light beam, and has the characteristics of high precision, fast cutting speed and low processing cost.

[0003] Patent publication number "CN217667183U" discloses a laser shearing machine for membrane structure carport production.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention. Example 1

[0020] Reference Figure 1-4 A laser shearing machine for the production of membrane structure carports includes a frame 1, a drive motor 7, a plate transmission part and a plate shearing part. The frame 1 includes an upper frame 2 and a lower frame 3. The drive motor 7 is fixedly installed on the lower frame 3 and a half gear 8 is coaxially fixedly connected to its output shaft.

[0021] The panel transmission part consists of a first roller 4, a second roller 5 and a transmission belt 6, which is used to transport the carport panels. The first roller 4 and the second roller 5 are symmetrically connected to the upper end of the upper frame 2, and the transmission belt 6 is connected between the first roller 4 and the second roller 5. A first transmission component for driving the transmission belt 6 is installed between the first roller 4 and the drive motor 7.

[0022] The first transmission assembly includes a first full gear 9, a first pulley 9 and a second pulley 11. The first full gear 9 is coaxially fixedly connected to the first pulley 9 and is rotatably mounted on the lower frame 3. The second pulley 11 is coaxially fixedly connected to the first rotating roller 4. The first pulley 9 and the second pulley 11 are connected by belt transmission. The first full gear 9 is intermittently meshed with the half gear 8.

[0023] The plate shearing part consists of a pair of fixed plates 14, a pair of guide rods 22, a laser guide head seat 23 and a laser guide head 24, which is used for laser shearing carport plates. A pair of fixed plates 14 are symmetrically fixedly installed on the upper end of the upper frame 3, a pair of guide rods 22 are symmetrically fixedly connected between the pair of fixed plates 14, and the two ends of the laser guide head seat 23 are respectively slidably sleeved on the pair of guide rods 22. The laser guide head 24 is fixedly installed on the laser guide head seat 23. A power component for driving the laser guide head seat 23 to move horizontally is installed between the pair of fixed plates 14, and a second transmission component for driving the power component to work is installed between the fixed plate 14 and the drive motor 7.

[0024] The power assembly includes a reciprocating screw 15, a screw nut 21 and a bending rod 25. The reciprocating screw 15 is rotatably connected between a pair of fixed plates 14. The screw nut 21 is threadedly connected to the reciprocating screw 15. One end of the bending rod 25 is fixedly connected to the screw nut 21, and the other end is fixedly connected to the laser guide head seat 23.

[0025] The second transmission assembly includes a second full gear 12, a third pulley 13 and a fourth pulley 16. The second full gear 12 and the third pulley 13 are coaxially fixedly connected and rotatably mounted on the lower frame 3. The fourth pulley 16 is coaxially fixedly connected to the reciprocating screw 15. The second full gear 12 is intermittently meshed with the half gear 8.

[0026] In this embodiment, after the machine is started, the drive motor 7 simultaneously drives the panel conveying and shearing sections via the half gear 8 on its output shaft. The unique design of the half gear 8 allows teeth to be present only on a portion of its circumference. Through intermittent engagement with the first full gear 9 and the second full gear 12, the motor's continuous rotation is converted into periodic motion, achieving the coordinated operation of intermittent fixed-length conveying of carport panels and reciprocating laser cutting. The specific working process is as follows: when cutting, first place the carport panel on the conveyor belt 6, then start the drive motor 7, when the tooth part of the half gear 8 is engaged with the first full gear 9, the power is transmitted to the first roller 4 through the first pulley 10, the belt, and the second pulley 11, driving the conveyor belt 6 to advance the set distance; then the half gear 8 disengages from the first full gear 9, and the conveyor belt 6 stops. At this time, the half gear 8 starts to engage with the second full gear 12, and the power drives the reciprocating screw 15 to rotate through the third pulley 13, the belt, and the fourth pulley 16, so that the screw nut 21 moves linearly along the guide rod 22, and drives the laser guide head seat 23 to move horizontally through the bending rod 25 to complete the cutting. After the cutting is completed, the screw nut 21 automatically returns to the initial position and enters the next cycle.

[0027] This time-sharing drive mechanism achieves precise synchronization of transmission and cutting actions through a purely mechanical structure: the laser guide head 24 starts cutting when the conveyor belt 6 stops, and the laser guide head 24 pauses when the conveyor belt 6 is running, effectively avoiding deviations caused by the movement of the plate during the cutting process. It should also be added that the present invention can control the single transmission distance and cutting stroke to millimeter-level accuracy by precisely designing the pulley diameter ratio and the reciprocating screw pitch, thereby realizing automated cutting of standardized lengths with an error controllable within ±0.5mm. The entire working cycle (transmission + cutting) takes only 2-3 seconds, and the theoretical maximum production capacity can reach 1,200 pieces / hour, meeting the needs of industrial mass production. Example 2

[0028] Reference Figure 1 and Figure 5 The difference between this embodiment and the first embodiment is that it also includes a plate cooling part, which is composed of a liquid storage tank 18, a bent pipe 26 and a plurality of spray nozzles 27, and is used to spray coolant onto the cutouts of the carport panels. The liquid storage tank 18 is fixedly mounted on the lower frame 3 and stores coolant inside. The bent pipe 26 is fixedly connected to the side walls of a pair of fixed plates 14. The plurality of spray nozzles 27 are all arranged at the lower end of the bent pipe 26 and are connected thereto. A pumping mechanism for pumping coolant into the bent pipe is installed on the lower frame 3.

[0029] The liquid pumping mechanism includes a liquid pump 17, a liquid inlet pipe 19 and a liquid outlet pipe 28. The liquid pump 17 is fixedly installed on the lower frame 3. The liquid inlet pipe 19 is connected between the liquid inlet end of the liquid pump 17 and the liquid storage tank 18. The liquid outlet pipe 28 is connected between the liquid outlet end of the liquid pump 17 and the bent pipe 26.

[0030] In this embodiment, after the laser guide head 24 completes the cutting action along with the laser guide head base 23, the liquid pump mechanism automatically starts, and the liquid pump 17 draws coolant from the liquid storage tank 18 through the liquid inlet pipe 19, and delivers it to the bend pipe 26 fixed to the side wall of the fixed plate 14 through the liquid outlet pipe 28. Finally, the coolant is sprayed onto the cut of the carport panel by multiple spray nozzles 27 at the lower end of the bend pipe 26. When the coolant contacts the high-temperature cut, it vaporizes and absorbs heat, lowering the cut temperature and flushing the molten residue at the cut. The cooling action and the cutting action are time-linked through a mechanical transmission or electrical control system. After the cutting is completed, the start and stop switch of the liquid pump 17 is triggered, such as by the travel switch of the reciprocating screw 15 or the motor speed signal, to ensure that cooling is only performed after cutting. The spraying duration is controlled by the running time of the liquid pump or the coolant flow rate to match the production rhythm. Example 3

[0031] Reference Figure 6 This embodiment differs from the first and second embodiments in that a cooling liquid chamber 30 and a cleaning liquid chamber 31 are provided within the liquid reservoir 18, each filled with cooling liquid and cleaning liquid, respectively. A liquid inlet pipe 19 communicates with the cooling liquid chamber 30 and has a branch pipe 32 at its midsection, which communicates with the cleaning liquid chamber 31. A first valve 20 is mounted on the liquid inlet pipe 19, located between the liquid reservoir 18 and the branch pipe 32. A second valve 33 is mounted on the branch pipe 32. A pressure boost valve 29 is mounted on the liquid outlet pipe 28.

[0032] In this embodiment, the partitioned design and valve control of the liquid reservoir 18 enable switching between coolant injection for cooling and cleaning fluid flushing for chip removal. During the cutting process, the first valve 20 is opened and the second valve 33 is closed. The liquid pump 17 draws coolant from the cooling liquid chamber 30, passes through the outlet pipe 28 and the boost valve 29, and then is sprayed onto the cut surface of the sheet metal by the spray nozzle 27 on the elbow 26, providing cooling and lubrication. If debris accumulates in the cutting area, the first valve 20 is closed and the second valve 33 is opened. The liquid pump 17 draws cleaning fluid from the cleaning liquid chamber 31, pressurizes it, and uses the spray nozzle 27 to flush the cutting area with high pressure to remove debris.

[0033] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
