Description

Technical Field

[0001] The present application relates to the field of laser cutting, and in particular to a laser tube cutting machine. Background Art

[0002] Laser tube cutting machine is mainly used for high-precision and high-efficiency cutting of tubes and profiles; it can cut tubes of various shapes and specifications, such as round, oval, square, etc., and can ensure high cutting quality, fast speed and small error. It can improve production efficiency and effectively reduce labor costs.

[0003] At present, when a laser tube cutting machine is cutting a tube, when cutting a long tube, in order to ensure the conveying effect of the cut tube, several unloading components are usually set at equal intervals in the unloading area, and several unloading components are used to drive the cut tube to move to the next station.

[0004] However, the current laser tube cutting machine has the following defects when cutting:

[0005] 1. The next time you need to cut a shorter pipe, you need to reconfigure the blanking components of the laser cutting machine. Since the pipes cut before are longer, the spacing between the blanking components is usually set larger. When you need to cut shorter pipes, you need to adjust the spacing between several blanking components to transport the shorter pipes, which is less convenient.

[0006] 2. When cutting the head and tail of the pipe, a slope is usually set below the cutting area. The cut pipe slides or rolls along the inclination angle of the slope and finally rolls into the storage groove or storage box. In the process of the head and tail moving into the storage groove after passing the slope, some of the head and tail will collide, which may cause the head and tail to deform. When the head and tail are reprocessed later, in order to ensure the quality of the recycled materials, it is necessary to further remove surface defects, which is less convenient. Summary of the invention

[0007] In order to solve the above problems, the present application provides a laser tube cutting machine.

[0008] The present application provides a laser tube cutting machine, which adopts the following technical solution:

[0009] A laser tube cutting machine comprises a machine body, wherein the machine body comprises a loading assembly, a clamping assembly, a cutting assembly, a cutting area discharge assembly, a unloading assembly and a pipe drive assembly, wherein the pipe drive assembly comprises a loading drive assembly and a unloading drive assembly, wherein the loading assembly is located at one end of the cutting assembly in the length direction, and the unloading assembly is located at the other end of the cutting assembly in the length direction, and the unloading assembly comprises a plurality of unloading chain machines, wherein the spacing between the plurality of unloading chain machines gradually increases from left to right, and a protective cover is provided on the outer cover of the machine body, wherein the cutting assembly comprises a laser cutting head slidably connected to the machine body for cutting pipes, and the clamping assembly comprises two chucks slidably connected to the machine body for clamping and rotating pipes, and the laser cutting head and the chuck are both located at the center of the machine body.

[0010] By adopting the above technical scheme, when processing the pipe, first place the pipe on the upper end of the feeding assembly, and convey the pipe through the feeding assembly. As the pipe moves to the position of the feeding drive assembly, the feeding drive assembly is used to drive the pipe to move, and the pipe is pushed to the cutting assembly, and the clamping assembly is used to clamp the pipe, and then the laser cutting head is used to cut the pipe. When the laser cutting head is used to cut the head and tail of the pipe, the head and tail fall to the cutting area discharge assembly due to gravity after being cut by the laser cutting head. A discharge trough can be set on the cutting area discharge assembly, and the cutting area discharge assembly is used to convey the head and tail to the discharge trough; the cut pipe is clamped by the unloading drive assembly, and then the pipe is driven to move, and then the pipe is placed on the unloading assembly, and a number of unloading chain machines are used to convey the pipe to complete the unloading of the pipe. The several unloading chain machines can convey pipes of different lengths, which are very convenient.

[0011] Optionally, the feeding assembly includes a plurality of feeding chain machines, which are arranged at equal intervals on one side of the length direction of the machine body, and a contact sensor for detecting the position of the pipe is arranged on one side of the length direction of the plurality of feeding chain machines, and the plurality of contact sensors are located at one end of the feeding chain machine close to the machine body.

[0012] By adopting the above technical solution, as the feeding chain machine drives the pipe to move, it contacts the contact sensor when it moves to the end of the feeding chain machine. At this time, the contact sensor detects the presence of the pipe. If the machine body stops suddenly or the power fails at this time, the presence of the pipe can still be detected after the machine body resumes operation, thereby ensuring the efficiency of subsequent pipe processing.

[0013] Optionally, each of the feeding chain machines is vertically slidably connected with a clamping device for adjusting the position of the pipe, and the plurality of clamping devices are located on the other side of the length direction of the feeding chain machine. The clamping device includes a clamping assembly 1 and a clamping assembly 2. The clamping device also includes a sliding plate, and a slide rail is horizontally arranged on the upper end of the sliding plate. The side of the slide rail close to the feeding chain machine is rotatably connected to two sprockets, and the two sprockets are respectively located at both ends of the slide rail in the length direction. A driving chain is provided on the outer sleeve of the two sprockets. The clamping assembly 1 includes a slider 1, and the slider 1 is connected to the upper end of the driving chain. The first and second slide blocks are fixedly connected to each other, the first and second slide blocks are fixedly connected to each other, the second slide block is fixedly connected to the first slide block, the second slide block is fixedly connected to the second slide block, and the third slide block is fixedly connected to the second slide block. A driving cylinder is horizontally arranged on the sliding plate, the piston rod of the driving cylinder is fixedly connected to the cylinder barrel of the lifting cylinder, and a rotating roller is rotatably connected to the upper end of the sliding plate, and the height of the rotating roller is higher than the height of the driving chain.

[0014] By adopting the above technical scheme, when using the feeding chain machine to transport the pipe, the piston rod of the lifting cylinder is operated to retract, thereby driving the clamping block 1 to move downward to make way for the pipe. As the pipe is transported, the pipe moves to the top of the clamping device. At this time, the piston rod of the driving cylinder is operated to extend, thereby driving the clamping block 1 and the clamping block 2 to move away from each other. After the distance between the clamping block 1 and the clamping block 2 is greater than the diameter of the pipe, the piston rod of the lifting cylinder is operated to extend, and the clamping block 1 moves upward to a height flush with the clamping block 2. Then the piston rod of the driving cylinder is operated to retract, thereby driving the clamping block 1 and the clamping block 2 to move toward each other to clamp the pipe. The position of the pipe can be adjusted by a plurality of clamping devices, thereby aligning the direction of the pipe with the clamping assembly, thereby improving the convenience of subsequent clamping of the pipe. As the feeding drive assembly pushes the pipe, the pipe moves on the rotating roller, and the rotating roller rotates, thereby improving the convenience of transporting the pipe.

[0015] Optionally, the cutting area discharging assembly includes a support plate, which is slidably connected to the machine body, and the upper end of the support plate is slidably provided with a receiving plate for receiving the pipe material, the support plate is rotatably connected to two flip cylinders, and the lower end of the support plate is provided with two extension plates, and the extension plates are rotatably connected to lifting cylinders, the piston rods of the two lifting cylinders are both rotatably connected to the support plate, the flip cylinder and the lifting cylinder are both located on the side of the support plate away from the machine body, the height of the flip cylinder is higher than the height of the lifting cylinder, two support plates are slidably connected to the support plate, the receiving plate is rotatably connected to the two support plates, the piston rod of each flip cylinder is rotatably connected to the receiving plate, an extension plate is fixedly connected to one side of the support plate, and a flip cylinder is rotatably connected to the extension plate, the piston rod of the flip cylinder is rotatably connected to the flip plate, and the cutting area discharging assembly also includes a conveyor belt, which is arranged below the support plate.

[0016] By adopting the above technical scheme, when cutting the head or tail of the pipe, the piston rods of the flipping cylinder and the lifting cylinder are operated to extend at the same time, and the receiving plate moves to the lower end of the pipe to be cut. As the head or tail falls to the upper end of the receiving plate, the piston rods of the flipping cylinder and the lifting cylinder are operated to retract at the same time, and then the piston rod of the flipping cylinder is operated to extend. At this time, the receiving plate is tilted, and the head or tail moves or rolls along the tilt angle of the receiving plate and falls to the upper end of the conveyor belt below. Then the conveyor belt can be used to move the head or tail to the next workstation. The impact force on the head or tail is small, which can effectively ensure the quality of the recycled materials.

[0017] Optionally, a material unloading lifting assembly is provided on one side of the length direction of each of the material unloading chain machines, and the material unloading lifting assembly includes a material unloading rack slidably connected to one side of the length direction of the material unloading chain machine, and a support plate is provided on the upper end of the material unloading rack, and the support plate and the material unloading rack are perpendicular to each other, and baffles are provided on both sides of the width direction of the support plate, and the two baffles are inclined away from the material unloading rack, and a material unloading roller is rotatably connected to the upper end of the material unloading rack, and the material unloading roller is located on one side of the length direction of the support plate, and a clearance plate is provided on the other side of the length direction of the support plate, and the clearance plate is inclined toward the direction close to the support frame.

[0018] By adopting the above technical scheme, after the cutting of the pipe is completed, several unloading racks are operated to move upward, thereby driving several pallets to move upward, and the pallets are moved to a position close to the pipe, and the unloading drive assembly is operated to drive the cut pipe to move. In the process of moving the pipe, the unloading roller rolls during the movement of the pipe, and supports the movement of the pipe. Then the pipe can be placed on the upper end of several pallets, thereby protecting the pipe. Then, several unloading racks are operated to move downward, and the pipe is lowered to the upper end of several unloading chain machines. The pipe is driven by several unloading chain machines to move to the next workstation, and the impact force on the pipe is small, thereby ensuring the product quality of the pipe.

[0019] Optionally, a plurality of the unloading chain machines are provided with a contact sensor 2 for detecting the position of the pipe, and the contact sensor 2 is located at one end of the unloading chain machine away from the machine body.

[0020] By adopting the above technical solution, as the unloading chain machine is transported, when the pipe moves to the position of contact sensor 2, it means that the pipe has reached the end of the unloading chain machine. If the machine body stops suddenly or a power outage occurs at this time, the presence of the pipe can still be detected after the machine body resumes operation, thereby ensuring the efficiency of subsequent pipe processing.

[0021] Optionally, the protective cover includes a cover one, which is arranged on the outside of the loading assembly and the unloading assembly, and the cover one includes a front plate, a top plate and a back plate, the back plate is fixedly connected to the body, the front plate is vertically slidably connected to the top plate, and the top plate is horizontally slidably connected to the back plate.

[0022] By adopting the above technical scheme, dust will be generated when cutting the pipe. By arranging a cover on the loading assembly and the unloading assembly, the loading assembly and the unloading assembly can be protected, thereby increasing the life of the loading assembly and the unloading assembly, and protecting the factory environment. If the machine body has problems such as equipment emergency stop or system failure, the front plate can be operated to slide up, and then the top plate can be operated to move toward the direction close to the back plate, and then the cover can be opened, and the staff can easily inspect the machine body, which is very convenient.

[0023] Optionally, the protective cover also includes a second cover, which is arranged on the outside of the cutting assembly. The second cover includes a front cover body, a rear cover body and a connecting part. The connecting part includes two connecting rods for connecting the front cover body and the rear cover body. One end of the two connecting rods in the length direction is fixedly connected to the front cover body, and the other end of the connecting rods in the length direction is fixedly connected to the rear cover body. An inspection port for viewing the cutting area is opened on the front cover body, and a sliding door for opening and closing the inspection port is slidably connected to the front cover body.

[0024] By adopting the above technical solution, if a problem or failure occurs in the cutting area, the machine body is operated to stop, and then the inspection port is opened by sliding the sliding door. The user can easily inspect the inside of the cutting area. Since the sliding door is sliding, the space occupied when opening and closing the sliding door can be effectively reduced.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When processing the pipe, first place the pipe on the upper end of the feeding assembly, and convey the pipe through the feeding assembly. As the pipe moves to the position of the feeding drive assembly, the feeding drive assembly is used to drive the pipe to move, push the pipe to the cutting assembly, clamp the pipe with the clamping assembly, and then cut the pipe with the laser cutting head.

As the head or tail falls to the upper end of the receiving plate, the piston rods of the flip cylinder and the lifting cylinder are retracted at the same time, and then the piston rod of the flip cylinder is extended. At this time, the receiving plate is tilted, and the head or tail moves or rolls along the tilt angle of the receiving plate and falls to the upper end of the conveyor belt below. Then, the conveyor belt can be used to move the head or tail to the next station. The impact force on the head or tail is small, which can effectively ensure the quality of the recycled materials;

The impact force on the pipe is small, thereby ensuring the product quality of the pipe.

[0058] Reference Figure 8 and Fig. 9 When cutting the pipe, if the length of the pipe to be cut is short, the unloading and lifting component 42 on the left side can take over the pipe, and the taking over effect is better; if the length of the pipe to be cut is long, the unloading and lifting components 42 on the left and right sides can both support the pipe, and can support and unload pipes of multiple lengths. The unloading component 4 has high applicability. When transporting pipes of different lengths, there is no need to adjust the spacing between several unloading chain machines 41, and it is very convenient.

The back plate 513 is fixedly connected to the body 1, the front plate 511 is vertically slidably connected to the top plate 512, and the top plate 512 is horizontally slidably connected to the back plate 513; since dust is generated in the cutting area when the pipe is cut, the cover 51 is arranged on the loading component 2 and the unloading component 4 to protect the loading component 2 and the unloading component 4, thereby improving the service life of the loading component 2 and the unloading component 4, and also protecting the factory environment; if the body 1 has problems such as equipment emergency stop or system failure, the front plate 511 can be operated to slide up, and then the top plate 512 can be operated to move in the direction close to the back plate 513, and then the cover 51 can be opened, and the staff can easily inspect and repair the body 1, which is very convenient.

[0062] Reference Figure 2 and Figure 5 When cutting the tailings of the pipe, the laser cutting head is operated to cut the pipe, and then the tailings of the pipe are cut off. The cut tailings fall due to gravity. As the tailings fall to the upper end of the receiving plate 32, the piston rods of the flipping cylinder 311 and the lifting cylinder 313 can be operated to retract at the same time, and then the piston rod of the flipping cylinder 311 can be operated to extend. At this time, the receiving plate 32 is tilted, and the tailings move or roll along the tilt angle of the receiving plate 32 and fall to the upper end of the conveyor belt below. Then the conveyor belt can be used to move the tailings or tailings to the next workstation. The impact force on the tailings or tailings is small, which can effectively ensure the quality of the recycled materials.

[0063] The working principle of a laser tube cutting machine in an embodiment of the present application is as follows: first, a tube is placed on the upper end of a feeding chain machine 21, and then the feeding chain machine 21 is driven to move the tube. As the tube moves to the position of the feeding drive assembly 13, the tube contacts the contact sensor 1 211, and at this time, the piston rod of the lifting cylinder 2213 is operated to extend, and the clamping block 1 2212 moves upward to a height flush with the clamping block 2222, and then the piston rod of the driving cylinder 2231 is operated to retract, thereby driving the clamping block 1 2212 and the clamping block 2222 to move. 22 move in the direction of approaching each other to clamp the pipe. The position of the pipe can be adjusted by a plurality of clamping devices 22, so that the direction of the pipe is aligned with the clamping assembly 11. As the pipe feeding drive assembly 13 pushes the pipe, the pipe moves on the rotating roller 227, and the rotating roller 227 rotates, thereby improving the convenience of conveying the pipe. Then, the clamping assembly 11 can be used to clamp the pipe, and the cutting assembly 12 can be used to cut the head or tail of the pipe. The cut head and tail fall onto the receiving plate 32. First, the receiving plate 32 is operated downward, and then the receiving plate 32 is operated to rotate, and the head or tail material moves or rolls along the inclination angle of the receiving plate 32 and falls to the upper end of the conveyor belt below, and then the conveyor belt can be used to move the head or tail material to the next station; if the pipe to be cut is short, the flap 36 is used to receive and guide the head or tail material, and the impact force on the head or tail material is small, which can effectively ensure the quality of the recycled material; after the cutting assembly 12 is used to complete the cutting of the pipe, the unloading drive assembly 14 is used to cooperate with the unloading The holding component 42 transports the pipe to the unloading chain machine 41. When cutting the pipe, if the length of the pipe to be cut is shorter, the unloading holding component 42 on the left can take over the pipe, and the taking over effect is better; if the length of the pipe to be cut is longer, the unloading holding components 42 on the left and right can both support the pipe, and can support and unload pipes of multiple lengths. The unloading component 4 has high applicability. When transporting pipes of different lengths, there is no need to adjust the spacing between several unloading chain machines 41, and it is very convenient.
