[0040] Please refer to the following: Figures 1 to 3 The present invention provides an online multi-head laser cutting machine for steel pipes and cold-formed steel. The online multi-head laser cutting machine for steel pipes and cold-formed steel includes a slide rail 11, a plurality of laser cutting main units 20, a plurality of lifting components, and a drive component. The slide rail 11 is fixedly installed; the plurality of laser cutting main units 20 are slidably installed on the slide rail 11 at intervals; there are at least two laser cutting main units 20 used to cut steel pipes or cold-formed steel; the plurality of lifting components are fixedly installed to support the steel pipes or cold-formed steel, and a lifting component is provided between every two adjacent laser cutting main units 20; the power output end of the drive component is connected to the laser cutting main unit 20 to drive the laser cutting main unit 20 to move synchronously with the steel pipe or cold-formed steel.

[0041] It should be noted that the laser cutting host 20 is an existing device with a clearance space in the middle for steel pipes or cold-formed steel sections to pass through. During cutting, the cutting head of the laser cutting host 20 moves around the steel pipe or cold-formed steel section once, cutting the steel pipe or cold-formed steel section into the specified length.

[0042] The slide rail 11 is fixed directly to the ground or other flat surfaces.

[0043] Preferably, the online multi-head laser cutting machine for steel pipes and cold-bent steel profiles is also equipped with a frame 10, and a slide rail 11 is fixed on the frame 10.

[0044] like Figure 3As shown, the bottom of the laser cutting host 20 is provided with a slider, which slides in conjunction with the slide rail 11, so that the laser cutting host 20 is slidably mounted on the slide rail 11; the side of the slide rail 11 is provided with a slot, and the side of the slider engages with the slot to prevent the laser cutting host 20 from tipping over.

[0045] The lifting component serves two purposes: firstly, to hold the steel pipe or cold-formed steel to prevent it from bending; and secondly, to support the cut steel pipe or cold-formed steel.

[0046] The online multi-head laser cutting machine for steel pipes and cold-formed steel provided in this embodiment is mainly used for cutting steel pipes or cold-formed steel with a length of less than 5m. Depending on the length of the steel pipe or cold-formed steel to be cut, part of the laser cutting host 20 can be selectively activated.

[0047] For example, when producing steel pipes or cold-formed steel sections less than 3m in length, three laser cutting hosts 20 are activated. In this case, the drive assembly drives the three laser cutting hosts 20 to move synchronously to cut the steel pipes or cold-formed steel sections. When producing steel pipes or cold-formed steel sections greater than 3m but less than 5m in length, two laser cutting hosts 20 are activated. In this case, the drive assembly only drives the two adjacent laser cutting hosts 20 to move synchronously to cut the steel pipes or cold-formed steel sections.

[0048] The beneficial effects of the online multi-head laser cutting machine for steel pipes and cold-formed steel provided by this utility model are as follows: Compared with the prior art, the online multi-head laser cutting machine for steel pipes and cold-formed steel provided by this utility model has at least two laser cutting hosts 20 slidably arranged on the slide rail 11, and a lifting component is set between adjacent laser cutting hosts 20 to support the steel pipe or cold-formed steel. When cutting the pipe, all laser cutting hosts 20 are started, and the drive component drives all laser cutting hosts 20 to move synchronously with the steel pipe or cold-formed steel. During this process, all laser cutting hosts 20 work simultaneously to cut the steel pipe or cold-formed steel, cutting off multiple sections of steel pipe or cold-formed steel at one time, greatly improving the cutting efficiency.

[0049] like Figure 1 and Figure 2 As shown in the embodiment of this utility model, the online multi-head laser cutting machine for steel pipes and cold-formed steel provides three laser cutting hosts 20 and two lifting components, which are used to cut three steel pipes or cold-formed steel at one time.

[0050] It should be noted that the number of laser cutting main units 20 can also be 2, 4, 5 or more, depending on the length of the steel pipe or cold-formed steel and the actual production length.

[0051] like Figure 1 and Figure 2As shown in the embodiment of the online multi-head laser cutting machine for steel pipes and cold-formed steel provided in this utility model, the lifting assembly includes a lifting frame 31 and several rollers 32. The lifting frame 31 is connected to two adjacent laser cutting hosts and moves synchronously with the laser cutting host 20. The several rollers 32 are arranged side by side on the upper side of the lifting frame 31 along the movement direction of the steel pipe or cold-formed steel to support the steel pipe or cold-formed steel.

[0052] Specifically, the laser cutting host 20 is equipped with a base, and the support frame 31 is detachably fixed to the base of the laser cutting host 20 by bolts. When cutting steel pipes or cold-bent steel of different lengths, the support frame 31 of different specifications is replaced.

[0053] like Figure 1 and Figure 2 As shown, in a specific embodiment of the online multi-head laser cutting machine for steel pipes and cold-formed steel provided in this utility model, a guide limiting groove 33 is also included. The guide limiting groove 33 is provided on the lifting frame 31 and is fixedly connected to the lifting frame 31. A plurality of rollers 32 are provided in the guide limiting groove 33 and are connected to the guide limiting groove 33.

[0054] Specifically, the guide limiting groove 33 is an upward-opening "U"-shaped groove, with an internal width slightly wider than the steel pipe or cold-formed steel section. It is detachably fixed to the lifting frame 31 by bolts or clamps, or directly welded to the lifting frame 31. Preferably, the guide limiting groove 33 is an upward-opening channel steel, with several idler rollers 32 evenly spaced inside the channel steel. The internal width of the channel steel is 0.5-10cm wider than the width of the steel pipe or cold-formed steel section.

[0055] During cutting, the steel pipe or cold-formed steel is confined within the guide limiting groove 33. The cut steel pipe or cold-formed steel is pushed forward by the steel pipe or cold-formed steel behind it, so as to facilitate continuous cutting and material discharge.

[0056] It should be noted that the guide limiting grooves 33 have different specifications, with different lengths and widths to match steel pipes or cold-formed steel sections of different widths and cutting lengths. Each guide limiting groove 33 is equipped with three or more idlers 32, the specific number depending on the length of the guide limiting groove 33.

[0057] like Figure 1 and Figure 2As shown in the embodiment of the online multi-head laser cutting machine for steel pipes and cold-formed steel provided in this utility model, the driving component includes several rigid connectors and a driving mechanism. The several rigid connectors are respectively disposed between two adjacent laser cutting hosts 20, and the two ends of the rigid connectors are respectively fixedly connected to the two adjacent laser cutting hosts 20. The power output end of the driving mechanism is connected to one laser cutting host 20 and is used to drive the laser cutting host 20 to slide along the slide rail 11.

[0058] It should be noted that the rigid connector is a rod of fixed length, with both ends connected to the laser cutting host 20. When cutting steel pipes or cold-bent steel of different lengths, the rod of different lengths is switched.

[0059] Furthermore, such as Figure 1 and Figure 2 As shown in the embodiment of the online multi-head laser cutting machine for steel pipes and cold-formed steel provided in this utility model, the rigid connecting member is a rod with adjustable length, including two screws 41 and a threaded tube 42. The two screws 41 are coaxially arranged, and the opposite ends of the two screws 41 are respectively connected to two adjacent laser cutting hosts 20; the threads on the two screws 41 have opposite directions; the threaded tube 42 is located between the two screws 41 and is screwed to the two screws 41 respectively.

[0060] By rotating the threaded tube 42 forward or backward, the total length of the rigid connector can be adjusted so that the distance between two adjacent laser cutting hosts 20 matches the length of the steel pipe or cold-formed steel to be cut.

[0061] Furthermore, the outer circumference of the threaded tube 42 is hexagonal to facilitate rotation of the threaded tube 42.

[0062] like Figure 1 and Figure 2 As shown in a specific embodiment of the online multi-head laser cutting machine for steel pipes and cold-formed steel provided in this utility model, the driving mechanism includes a rack 53, a motor assembly 51, and a gear 52. The rack 53 is arranged parallel to one side of the slide rail 11 and is fixedly installed. The motor assembly 51 is fixedly connected to the laser cutting host 20. The gear 52 is connected to the power output end of the motor assembly 51 and meshes with the rack 53.

[0063] It should be noted that both the slide rail 11 and the rack 53 are mounted on the frame 10, and there are two slide rails 11 arranged in parallel. Both the gear 52 and the rack 53 are helical gears, resulting in more stable transmission.

[0064] The motor assembly 51 is an existing device consisting of a motor and a reducer, and can also be a stepper motor or a servo motor.

[0065] In addition, the drive assembly can also be a motor and a lead screw driven by the motor, with a slider on the laser cutting host 20 that is threadedly engaged with the lead screw. Alternatively, the drive assembly can be replaced by a hydraulic cylinder.

[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
