Description

Technical Field

[0001] The present invention relates to the technical field of metal tube processing, and particularly relates to a metal tube laser cutting device. Background Art

[0002] Laser cutting refers to using a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporating to form holes. As the beam moves relative to the material, the holes continuously form a very narrow slit, completing the cutting of the material. That is, by irradiating the workpiece with a focused high-power density laser beam, the irradiated material is quickly melted, vaporized, ablated or reaches the ignition point. At the same time, the molten material is blown away by a high-speed gas flow coaxial with the beam, thereby realizing the cutting of the workpiece. It belongs to one of the thermal cutting methods. In the process of cutting and processing metal tubes, in order to avoid the problem of deformation of the metal tube caused by traditional cutting knives, laser cutting is often used to cut the metal tube.

[0003] In the prior art, when traditional metal tubes are laser cut, after cutting is completed at one end of the metal tube, manual unloading and subsequent feeding of the pipe fittings are often required, resulting in low efficiency. Moreover, manual control of the switch of the laser cutting head is required, consuming labor. For this reason, we propose a metal tube laser cutting device to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, such as: when traditional metal tubes are laser cut, manual unloading and loading operations are required, resulting in low efficiency, and the switch of the laser cutting head also needs to be manually controlled, consuming labor. A metal tube laser cutting device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A metal tube laser cutting device includes a base. Two sliding seats are slidably arranged on the base. Side plates are fixedly arranged on both of the two sliding seats. A chute corresponding to the two sliding seats is opened on the base. One side sliding seat is connected to one side side wall of the chute through a first spring. A material clamping mechanism is arranged on the side plate of the sliding seat. A corresponding limiting mechanism is arranged on the other side sliding seat. A back plate is fixedly arranged on the base. A top plate is fixedly arranged on the back plate. A sliding plate is slidably arranged on the top plate. A transmission mechanism corresponding to the sliding plate is arranged on the top plate. A laser cutting head is fixedly arranged on the lower wall of the sliding plate. The laser cutting head slidably penetrates through the top plate. A sliding opening corresponding to the laser cutting head is opened on the top plate. Two control switches corresponding to the laser cutting head are symmetrically and fixedly arranged on the top plate. The two control switches are arranged on both sides of the sliding plate. A unloading mechanism is also arranged on the sliding plate.

[0007] Preferably, the clamping mechanism includes two clamping plates, and the two clamping plates are both slidably arranged on the side plates through sliders. The side plates are provided with side grooves corresponding to the sliders, and a threaded rod is rotatably arranged in the side grooves. The threaded rod rotates and passes through the two sliders. The two sliders are provided with threaded through holes corresponding to the threaded rods, and the threads at both ends of the threaded rods are arranged in opposite directions. One end of the threaded rod rotates and passes through the upper wall of the side plate and is fixedly connected with a turning handle.

[0008] Preferably, the limiting mechanism includes two clamping blocks, and telescopic grooves corresponding to the clamping blocks are provided on both side walls of the sliding seat. The two clamping blocks are respectively slidably arranged in the two telescopic grooves, and the two clamping blocks are connected to the inner wall of the telescopic groove through a second spring. A number of clamping grooves corresponding to the clamping blocks are symmetrically provided on both side walls of one end of the sliding groove, and the two clamping blocks are provided with corresponding toggle mechanisms.

[0009] Preferably, the toggle mechanism comprises two toggle rods, which are respectively fixed on the side walls of the two blocks, and both slide through the upper wall of the slide seat, and the slide seat is symmetrically provided with two strip-shaped sliding openings corresponding to the toggle rods.

[0010] Preferably, the transmission mechanism includes a motor, the motor is fixedly arranged on the upper wall of the top plate, a rotating rod is fixedly arranged on the output end of the motor, a rotating wheel is fixedly arranged on the end of the rotating rod away from the motor, a transmission groove corresponding to the rotating wheel is opened on the side wall of the skateboard, the rotating wheel is rotatably set in the transmission groove, a half circle of latching teeth is fixedly arranged circumferentially on the side wall of the rotating wheel, and latching tooth grooves corresponding to the latching teeth are opened on the side walls on both sides of the transmission groove.

[0011] Preferably, the unloading mechanism includes a back plate, which is slidably arranged on a side plate away from the clamping plate, and is connected to the slide plate through a connecting rod. The connecting rod is L-shaped, and one end of the side wall of the back plate close to the clamping plate is inclined.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the clamping plate is controlled by the cooperation of the threaded rod and the slider, and the two clamping plates can be driven closer or farther away when the rotating handle drives the threaded rod to rotate, thereby realizing the rapid clamping and fixing of metal pipes of different models and sizes on the side plates, and improving the adaptability of the device; the metal pipe is pressed against the side plate on the other side by setting the first spring, and the restricted fixation of the slide seat on the other side is realized by setting the clamping block, thereby realizing the rapid fixation of the side plate on the other side; the clamping block is controlled by setting the lever, and the lever can be driven to slide the clamping block out of the slot, thereby releasing the restricted fixation of the slide seat on the side away from the clamping plate on the base; the cutting length of the metal pipe can be quickly adjusted by adjusting the position of the side plate where the slide plate is located, so that the device can adapt to the requirements of cutting different lengths of metal pipes, further improving the adaptability of the device; the sliding plate is pushed by the cooperation of the rotating wheel and the transmission groove, When the motor drives the wheel to rotate in the transmission groove, the teeth on the wheel push the tooth groove in the transmission groove to move, thereby driving the slide plate to slide back and forth, and thus driving the laser cutting head to slide back and forth. When the slide plate moves to the side away from the back plate and squeezes the control switch, the cutting of the metal pipe can be completed and the laser cutting head can be automatically closed. As the slide plate continues to move and reset, when the control switch close to the back plate is squeezed, the laser cutting head can be turned on for the next cutting operation. After one laser cutting is completed, as the slide plate moves to the side away from the back plate, it can drive the back plate to move to the side away from the back plate, thereby allowing the inclined side wall of the back plate to move toward the position where the metal pipe is against, and then the cut end can be loosened and fall. At this time, the first spring pushes the slide seat to move so that the subsequent metal pipe can resist the back plate again, thereby completing the automatic unloading and loading operations. There is no need for manual unloading and loading, which greatly improves the cutting efficiency of the metal pipe. BRIEF DESCRIPTION OF THE DRAWINGS

The control of the clamping plate 8 is realized through the cooperation of the threaded rod 6 and the slider 7.When the handle 9 is turned to drive the threaded rod 6 to rotate, the two clamping plates 8 can be driven to move closer or farther away, thereby realizing the rapid clamping and fixing of metal pipes of different sizes on the side plate 10, thereby improving the adaptability of the device. By setting the first spring 4, the metal pipe is pressed against the side plate 10 on the other side. By setting the clamping block 23, the restriction and fixation of the slide seat 2 on the other side is realized, thereby realizing the rapid fixation of the side plate 10 on the other side.
