Description

Technical Field

[0001] The present application relates to the technical field of laser cutting machines, and in particular to an automatic blanking device for laser cutting machines. Background Art

[0002] Against the backdrop of rapid manufacturing development, laser cutting, as an indispensable part of modern manufacturing, will take a leading position in the future development of manufacturing.

[0003] There are two blanking methods for existing laser tube cutting machines: manual blanking and automatic blanking. During the automatic blanking process, a blanking device is required to support the tube to ensure cutting accuracy. The existing blanking device has the problem of insufficient support for shorter or longer tubes, which in turn affects the accuracy of laser cutting. For example, a laser tube cutting machine blanking device is disclosed in the Chinese utility model patent with application number 202120299644.0, which supports the suspended tubes during the cutting process and collects the materials through the finished material rack. However, the rising support mechanism of the device is a certain distance away from the position of the laser cutting head at the front end of the device, and cannot support the tubes within this distance, affecting the cutting accuracy of the tubes. In addition, when the existing laser cutting machine cuts the pipe, the laser cutting head cuts the pipe under the control of the program, and the cut pipe falls freely on the rack. The cut pipe is very easy to deform and damage when it hits the rack or the ground when it falls. When there are too many pipes falling near the rack, it is necessary to manually move these cut pieces to the pallet. When the cut pieces are long and heavy, multiple workers are required to cooperate in the transportation. Since the space at the rack is relatively narrow, it is inconvenient and unsafe to carry them manually. At the same time, the fallen pipe cut pieces are very messy and unsightly. Workers have to sort them out when packing and transporting them, which is very inconvenient and consumes too much manpower. Utility Model Content

[0007] The automatic blanking device for laser cutting machine provided in this application also includes the following additional technical features:

[0008] The frame includes a bottom frame and a material-dropping inclined plate. The front material receiving piece, the rear material-dropping mechanism and the material-dropping inclined plate are respectively installed on the bottom frame. The material-dropping inclined plate is located directly above the rear material-dropping mechanism and is tilted toward the material storage trough. The bottom edge of the material-dropping inclined plate is engaged with the upper edge of the material storage trough, and the material-dropping inclined plate is provided with an avoidance window for avoiding the rear material receiving piece.

[0009] The front material receiving member comprises a support plate and a waste material blanking plate rotatably connected to the front end of the support plate, and the waste material blanking plate is driven by a waste material flipping cylinder to realize flipping relative to the support plate.

[0010] The front blanking mechanism also includes a fixed seat, which is fixed to the frame. The fixed seat is provided with a slide rail and slider mechanism. A lifting bracket is installed on the slider. The support plate is installed on the lifting bracket. The first lifting mechanism drives the support plate to reciprocate in the vertical direction through the lifting bracket.

[0011] The turning mechanism comprises a plurality of unloading turning cylinders arranged side by side, the cylinder barrels of the unloading turning cylinders are connected to the lifting bracket, and the two ends of the support plate are respectively hinged to the lifting bracket and the piston rods of the unloading turning cylinders.

[0012] The rear support unit also includes a base, which is fixed to the frame. The second lifting mechanism is configured as a lifting cylinder installed on the base, and the rear material receiving member is slidably installed on the base along a vertical direction.

[0014] An elastic buffer structure is arranged on the inner surfaces of the flat plate, the guide inclined plate and the vertical plate for cooperating to form the material storage trough.

[0015] The vertical plate is detachably mounted on the supporting frame.

[0016] An adjusting member capable of adjusting the height of the supporting frame is installed at the bottom of the supporting frame; and / or a roller is installed at the bottom of the supporting frame.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application include at least:

[0018] 1. The automatic blanking device for laser cutting machine provided by the present invention can arrange the front blanking mechanism close to the cutting head of the laser cutting machine, and the rear blanking mechanism is located at the rear side of the front blanking mechanism. The front material connection piece is lifted by the first lifting mechanism and the rear material connection piece is lifted by the second lifting mechanism, both of which can support the pipe. When it is necessary to support short pipes, only the front blanking mechanism can be operated, and the blanking support requirements for short pipes can be met by the front material connection piece; when it is necessary to support long pipes, a suitable number of rear material connection pieces can be selected according to the length of the pipe to support the blanking of the pipe together with the front material connection piece. In other words, the longer the length of the pipe, the more rear blanking units can be selected to participate in the support. Therefore, the device has higher adaptability to pipe blanking, can realize the automatic blanking function of pipes of various sizes, and helps to improve the cutting accuracy of pipes. The cut pipes can be turned over by running the flipping mechanism to flip the front material receiving piece toward the storage trough, so that the pipes on the front material receiving piece can fall into the storage trough in an orderly manner. The pipes can be automatically collected and sorted through the storage trough, reducing the labor intensity of workers, saving labor and improving safety.

[0019] 2. The blanking inclined plate is located directly above the rear blanking mechanism and is inclined toward the storage trough, and the bottom edge of the blanking inclined plate is engaged with the upper edge of the storage trough, so that after the pipe is cut, as the front material receiving piece and the rear material receiving piece gradually fall to the height of the blanking inclined plate, as the front material receiving piece flips toward the storage trough and keeps the front material receiving piece and the blanking inclined plate tilted and flush, the pipe will be guided by the inclined blanking inclined plate and slide into the storage trough under the action of gravity, which helps to weaken the impact force on the cut pipe during the blanking process, effectively prevents the pipe from deformation and damage, and also helps the pipe to slide more neatly into the storage trough, facilitating the collection of the pipe.

[0020] 3. The front material receiving part includes a pallet and a waste blanking plate rotatably connected to the front end of the pallet. The waste blanking plate is flipped relative to the pallet by the drive of the waste flipping cylinder. Therefore, the waste generated during the pipe cutting process is collected on the waste blanking plate. When a certain amount of waste is collected, the waste flipping cylinder can be operated to drive the waste blanking plate to flip and unload the waste to the designated area to facilitate waste collection.

[0021] 4. The storage trough is surrounded by a flat plate, a guide inclined plate and a vertical plate. The front receiving piece discharges the material toward the storage trough through the guide inclined plate, so that during the pipe dropping process, it can slowly enter the storage trough under the guidance of the guide inclined plate, avoiding the free fall of the pipe, effectively preventing the deformation and damage of the pipe, and also helping the pipe to slide into the storage trough more neatly, making it convenient for pipe collection.

[0038] In the embodiment of the present application, an automatic blanking device for a laser cutting machine is provided. For the convenience of explanation and understanding, the following contents provided in the present application are all described based on the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only used as a specific example and schematic description, and cannot constitute a specific limitation on the technical solution provided in the present application.

[0039] like Figures 1 to 5 As shown, an automatic blanking device for a laser cutting machine provided in the present application includes a frame 1, a material storage device 2, a front blanking mechanism 3 and a rear blanking mechanism 4, wherein the material storage device 2 includes a support frame 21 and a storage trough 22 arranged on the support frame 21; the front blanking mechanism 3 is installed on the front side of the frame 1, including a front material receiving piece 31, a first lifting mechanism 35 capable of driving the front material receiving piece 31 to reciprocate in the vertical direction, and a flipping mechanism capable of driving the front material receiving piece 31 to flip toward the storage trough 22; the rear blanking mechanism 4 is installed on the rear side of the frame 1, including a plurality of rear support units 41 arranged at intervals along the front and rear directions of the frame 1, and the rear support unit 41 includes a rear material receiving piece 411 and a second lifting mechanism 412 capable of driving the rear material receiving piece 411 to reciprocate in the vertical direction. It should be noted that the front side of the frame 1 is defined as the side of the frame 1 close to the cutting station of the laser cutting machine (where the pipe is cut by the cutting head), and the rear side of the frame 1 is the side of the frame 1 away from the cutting station of the laser cutting machine.

[0040] The automatic blanking device for laser cutting machine provided by the present invention is ingenious in conception and reasonable in structure. The front blanking mechanism 3 can be arranged close to the cutting head of the laser cutting machine, and the rear blanking mechanism 4 is located at the rear side of the front blanking mechanism 3. The front material receiving piece 31 is lifted by the first lifting mechanism 35 and the rear material receiving piece 411 is lifted by the second lifting mechanism 412, both of which can support the pipe. When it is necessary to support short pipes, only the front blanking mechanism 3 can be operated, and the blanking support requirements for short pipes can be met by the front material receiving piece 31; when it is necessary to support long pipes, a suitable number of rear material receiving pieces 411 and the front material receiving piece 31 can be selected according to the length of the pipe to support the pipe blanking together. In other words, the longer the length of the pipe, the more rear blanking units can be selected to participate in the support. Therefore, the device has higher adaptability to pipe blanking, can realize the automatic blanking function of pipes of various sizes, and helps to improve the cutting accuracy of pipes. After the pipe cutting is completed, the front material receiving piece 31 can be flipped toward the storage trough 22 by operating the flipping mechanism, so that the pipes on the front material receiving piece 31 fall into the storage trough 22 in an orderly manner, and the pipes are automatically collected and sorted through the storage trough 22, which reduces the labor intensity of workers, saves labor, and improves safety. Figure 1 and Figure 2Schematically depicting an embodiment in which the rear blanking mechanism 4 includes four rear support units 41 , this does not limit the present application, and the rear support units 41 may also be other suitable numbers.

[0041] As a preferred embodiment, Figure 1 and Figure 2 As shown, the frame 1 includes a bottom frame 11 and a blanking inclined plate 12, the front material receiving piece 31, the rear material blanking mechanism 4 and the blanking inclined plate 12 are respectively installed on the bottom frame 11, the blanking inclined plate 12 is located directly above the rear material blanking mechanism 4 and is tilted toward the storage tank 22, the bottom edge of the blanking inclined plate 12 is engaged with the upper edge of the storage tank 22, and the blanking inclined plate 12 is provided with an avoidance window 121 for avoiding the rear material receiving piece 411. Specifically, by setting the avoidance window 121, when the second lifting mechanism 412 drives the rear material receiving piece 411 to rise, the rear material receiving piece 411 can rise through the avoidance window 121 to support the pipe. Those skilled in the art can understand that the blanking inclined plate 12 is located directly above the rear blanking mechanism 4 and is tilted toward the storage trough 22, and the bottom edge of the blanking inclined plate 12 is engaged with the upper edge of the storage trough 22, so that after the pipe is cut, when the front material receiving piece 31 and the rear material receiving piece 411 gradually fall to the height of the blanking inclined plate 12, as the front material receiving piece 31 flips toward the storage trough 22 and keeps the front material receiving piece 31 tilted and flush with the blanking inclined plate 12, the pipe will be guided by the tilt of the blanking inclined plate 12 and slide into the storage trough 22 under the action of gravity, which helps to weaken the impact force received by the cut pipe during the blanking process, effectively prevents the pipe from deformation and damage, and also helps the pipe to slide more neatly into the storage trough 22, facilitating the collection of the pipe.

[0042] As a preferred embodiment, Figure 3 As shown, the front receiving member 31 includes a support plate 311 and a waste material blanking plate 312 rotatably connected to the front end of the support plate 311. The waste material blanking plate 312 is flipped relative to the support plate 311 by the drive of the waste material flipping cylinder 37. The waste generated during the pipe cutting process is collected on the waste material blanking plate 312. When a certain amount of waste is collected, the waste material flipping cylinder 37 can be operated to drive the waste material blanking plate 312 to flip and unload the waste to a designated area. For example, a waste storage box can be placed under the support plate 311, so that the waste material can be unloaded into the waste storage box after the waste material blanking plate 312 is flipped, which is convenient for waste collection. After the waste is unloaded, the waste material blanking plate 312 is driven by the waste flipping cylinder 37 to flip back to achieve return.

Specifically, when the first lifting mechanism 35 is required to drive the support plate 311 to move in the vertical direction, the first lifting mechanism 35 is operated to drive the lifting bracket 34 to move, and the lifting bracket 34 will drive the slider to slide relative to the slide rail, and the support plate 311 moves up and down with the lifting bracket 34. The setting of the lifting bracket 34 can provide reliable support for the support plate 311, thereby improving the carrying capacity of the support plate 311. In a preferred embodiment, the first lifting mechanism 35 can use a motor screw mechanism, and of course, other suitable mechanisms can also be used, such as a cylinder, an oil cylinder, etc., which are not limited here.

Specifically, the piston rod of the unloading flip cylinder 36 can be hinged to one end of the support plate 311 close to the material storage tank 22 through a fisheye joint, and the switching of the support plate 311 from the horizontal state to the inclined state is realized by contracting the piston rod of the unloading flip cylinder 36, and the switching of the support plate 311 from the inclined state to the horizontal state is realized by extending the piston rod of the unloading flip cylinder 36.

It can be understood by those skilled in the art that the material storage trough 22 is surrounded by the flat plate 23, the guide inclined plate 24 and the vertical plate 25, and the front material receiving member 31 discharges materials toward the material storage trough 22 through the guide inclined plate 24, so that during the process of pipe material dropping, it can be guided by the guide inclined plate 24 to slowly enter the material storage trough 22, avoiding the free fall of the pipe material, effectively preventing the deformation and damage of the pipe material, and also helping the pipe material to slide into the material storage trough 22 more neatly, facilitating the collection of the pipe material.

[0047] In a preferred embodiment, Figure 4 As shown, an elastic buffer structure 26 is arranged on the inner surface of the flat plate 23, the guide inclined plate 24 and the vertical plate 25 for forming the storage tank 22. The arrangement of the elastic buffer structure 26 can realize elastic buffering when the pipe enters the storage tank 22, effectively prevent the pipe from directly contacting and colliding with the surface of the storage tank 22, and reduce the damage to the pipe surface caused by bumps. Preferably, the elastic buffer structure 26 can be a rubber pad or other elastic structure, and the elastic buffer structure 26 can be installed on the inner surface of the flat plate 23, the guide inclined plate 24 and the vertical plate 25 by mushroom head screws.

Specifically, the vertical plate 25 can be installed on the front side of the plane of the support frame 21 by plugging and fastened by screws. When unloading heavy pipes or batches of pipes from the flat plate 23, the vertical plate 25 can be removed from the support frame 21, which is more convenient for unloading pipes.

[0051] During the specific operation of the device, when the tube is output from the cutting position of the laser cutting machine to the blanking device above the front blanking mechanism 3, the first lifting mechanism 35 of the front blanking mechanism 3 drives the lifting bracket 34 to rise, thereby driving the support plate 311 to rise to the tube lifting position; when the tube is further extended to the top of the rear blanking mechanism 4, a suitable number of second lifting mechanisms 412 are selected to drive the rear receiving piece 411 to rise and contact the tube, thereby playing the role of supporting the tube together with the support plate 311; when the tube completes the cutting process, the first lifting mechanism 35 drives the support plate 311 to rise to the tube lifting position; when the tube is further extended to the top of the rear blanking mechanism 4, the second lifting mechanism 412 is ...

At this time, the pipe is on the support plate 311 and the blanking inclined plate 12, and will fall along the inclined surface due to gravity, and then fall to the guide inclined plate 24, and then continue to guide the inclined plate 24 to slide to the flat plate 23 for storage. The vertical plate can be removed from the support frame 21, and then the cut pipe can be taken out from the storage tank 22.
