Description

Technical Field

[0001] This utility model relates to the field of pipe cutting machine feeding technology, and in particular to a multi-pipe cutting machine feeding mechanism. Background Technology

[0002] A pipe cutter is a tool used to cut pipes made of metal, plastic, etc.

[0003] A laser cutting machine is a high-precision, high-efficiency cutting device that uses a laser beam to cut materials. Its working principle is as follows:

[0004] The laser emitted by the laser is focused into a high-power-density laser beam by the optical path system; the laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point, while high-pressure gas coaxial with the beam blows away the molten or vaporized metal; as the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thereby achieving the purpose of cutting.

[0005] The feeding mechanism of the pipe cutting machine is an important component of the pipe cutting machine. It is responsible for automatically or manually feeding the pipe to the cutting position for subsequent cutting operations.

[0006] Chinese Patent Publication No. CN205057632U discloses a feeding mechanism for a pipe cutting machine, including a feeding frame and a slide table connected to the outlet of the feeding frame. A tilting plate for controlling the feeding is provided inside the feeding frame. A sliding groove is provided inside the slide table, the edge of which is connected to the outlet of the feeding frame. A top block is provided inside the sliding groove. A long-stroke cylinder is provided at one end of the slide table, and the top rod of the long-stroke cylinder is connected to the top block. A blocking mechanism is provided at the other end of the slide table.

[0007] The above-mentioned patents still have the following shortcomings in practice:

[0008] The aforementioned patent uses a flip-board to allow individual release of pipes placed in the feeding frame before cutting. While this achieves the purpose of feeding, it requires manual placement of the pipes in the feeding frame before cutting, which reduces work efficiency. Utility Model Content

[0009] The main purpose of this utility model is to provide a feeding mechanism for a multi-pipe cutting machine, which can effectively solve the problem that the cutting machine cannot automatically clamp and move during feeding.

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, a multi-tube cutting machine feeding mechanism includes a support frame 9 and a laser tube cutting machine 7. A power distribution box 2 is fixedly connected to the rear right end of the support frame 9. An operating table 1 is fixedly connected to the rear upper end of the power distribution box 2. Conveying devices 4 are installed on the left, middle and right sides of the upper end of the support frame 9. A drive shaft 10 is fixedly connected to the front and rear sides of the part of the left and middle conveying devices 4 that are close to each other. A guide rod 8 is fixedly connected to the front and rear sides of the right side of the upper end of the support frame 9. Several movable conveying device position locking columns 3 are fixedly connected to the front and rear edges of the upper end of the operating table 1. A servo feeding arm mechanism 6 is slidably connected to the upper front of the three conveying devices 4. A limit baffle plate 5 is slidably connected to the left end of the operating table 1.

[0034] The conveying device 4 located on the left and middle parts is fixedly connected to the upper end of the support frame 9, and the conveying device 4 located on the right part is slidably connected to the outer surface of the two guide rods 8.

[0035] This device is powered by industrial electricity.

[0036] In the above process, the raw material to be cut is first placed on three conveying devices 4. Then, the control panel 1 is used to move the raw material placed on the conveying devices 4 forward. When the raw material moves to the front of the conveying device 4, the control panel 1 controls the servo feeding arm mechanism 6 to move backward, and at the same time controls the conveying device 4 to lift the raw material. When the servo feeding arm mechanism 6 moves below the raw material, the control panel 4 controls the conveying device 4 to move the raw material downward. After the movement is completed, the control panel 1 controls the servo feeding arm mechanism 6 to clamp the raw material. After clamping, the control panel 6 controls the servo feeding arm mechanism 6 to drag the raw material forward, so that the raw material is placed on the upper part of the laser tube cutter 7, so that the laser tube cutter 7 can perform laser cutting on the raw material. After the cutting is completed, the material is reloaded, and the above operation is repeated.

[0037] The number of conveying devices 4 can be increased as needed, as described above.

[0038] In the above description, the positions of the conveying devices 4 located on the left and right sides are relatively fixed, while the conveying device 4 located on the right side can be controlled to slide on the outer surface of the guide rod 8. The purpose of this is:

[0039] The left and middle conveying devices 4 are suitable for clamping profiles with a length of 4-5M. When the right conveying device 4 is added, the distance of movement can accommodate pipe lengths of 4.8-6M, 6-7.5M, 7.5-8.4M, and 8.5-9.1M respectively, improving the integrity of the device.

[0040] In the above, the position locking column 3 of the moving conveyor device can fix the position of the conveyor device 4 located on the right after adjustment and movement, so that it will not shift during implementation, thus improving the integrity of the device.

[0041] In the above, the conveying device 4 located in the middle transmits power to the conveying device 4 located on the left through the action of the drive shaft 10.

[0042] In the above, the limiting baffle 5 can limit the protruding length of the left side of the material, so that the left side of the material will not protrude too much, and the material can be stably clamped by the servo feeding arm mechanism 6.

[0043] In the above-mentioned system, control panel 1 uses an Omron PLC and a Weintek touchscreen; it features teach-and-memory programming and can switch between automatic and manual feeding modes to suit different working conditions. The system has comprehensive detection, fault self-diagnosis, interlocking, alarm, and protection functions. Other functions such as debugging, setting, and manual operation are all integrated into the touchscreen, making it very intuitive.

[0044] Furthermore, in order to achieve the purpose of conveying the raw material to the front by the conveying device 4, then lifting the raw material, and finally clamping it by the servo feeding arm mechanism 6, see [reference needed]. Figure 7 and Figure 10The conveying device 4 includes a fixed frame 48, which is fixedly connected to the upper end of the support frame 9. A servo motor 42 is fixedly connected to the rear left end of the fixed frame 48. The output end of the servo motor 42 is fixedly connected to the steering gear 41. A transmission assembly 46 is fixedly connected to the front left end of the fixed frame 48. A conveying assembly 43 is rotatably connected inside the fixed frame 48. A rectangular block 44 is fixedly connected to the outer surface of the conveying assembly 43. A lifting and distributing assembly 45 is fixedly connected to the front edge of the left end of the fixed frame 48.

[0045] Two drive shafts 10 are fixedly connected between two steering gears 41 located on the same side;

[0046] The servo feeding arm mechanism 6 includes a sliding module 64, which is slidably connected to the upper front side of the right end of the fixed frame 48. A pneumatic clamping device 63 is fixedly connected to the right end of the sliding module 64, a material support plate 62 is fixedly connected to the front of the left end of the sliding module 64, and a rotating baffle 61 is fixedly connected to the front end of the sliding module 64.

[0047] In the above process, the servo motor 42 and transmission assembly 46 are started to rotate. The servo motor 42 transmits power to the steering gear 41, which in turn drives the transmission assembly 43 and the drive shaft 10 to rotate. The transmission assembly 43 and the drive shaft 10 located at the rear rotate, and the transmission assembly 46 drives the drive shaft 10 located at the front to rotate. This causes the servo motor 42 and transmission assembly 46 to transfer power to the servo motor 42 located on the left to rotate. When the servo motor 42 rotates, it drives the rectangular block 44 connected to it to rotate, causing the rectangular block 44 to drag the raw material to the front. After the dragging is completed, the lifting and distributing assembly 45 is started to move, causing the lifting and distributing assembly 45 to lift the raw material upward. After the movement is completed, the material is then... The sliding module 64 is controlled to move backward via the control panel 1, which in turn moves the rotating baffle 61, the material support plate 62, and the pneumatic clamping device 63 backward together. When the raw material is placed above the rotating baffle 61, the sliding module 64 stops moving. Then, the lifting and distributing assembly 45 is controlled to move upward, lowering the raw material onto the material support plate 62, so that the material support plate 62 supports the raw material. Then, the pneumatic clamping device 63 is controlled to move forward, so that the pneumatic clamping device 63 and the rotating baffle 61 work together to clamp the raw material. After clamping, the sliding module 64 is started to move forward, moving the raw material forward together. After moving above the laser tube cutter 7, the sliding module 64 stops moving, and the laser tube cutter 7 then cuts the raw material.

[0048] In the above, the height of the material support plate 62 can be adjusted via the locking screw hole.

[0049] In the above, the pneumatic clamping device 63 is composed of cylinder two and clamping plate. Cylinder two is fixedly connected to the rear right end of the sliding module 64, and clamping is fixedly connected to the output end of cylinder two.

[0050] In the above, the transmission assembly 43 consists of four sprockets and a chain. The four sprockets are rotatably connected to the upper and lower parts of the front and rear sides of the fixed frame 48, respectively. The chain is wound around the outer surface of the four sprockets. The two sprockets located at the lower part are connected to the steering gear 41 and the transmission assembly 46, respectively.

[0051] Furthermore, in order to achieve the purpose of the lifting and distributing assembly 45 lifting the raw materials and the transmission assembly 46 transmitting power to the sprocket on the left, see [reference needed]. Figure 9 The lifting and distributing assembly 45 includes a cylinder 452, which is fixedly connected to the front left end of the rectangular block 44. The output end of the cylinder 452 is fixedly connected to a top plate 451, which is slidably connected to the front left edge of the rectangular block 44.

[0052] The transmission assembly 46 includes a stepper motor 461, which is fixedly connected to the front left end of the rectangular block 44. The output end of the stepper motor 461 is fixedly connected to a steering gear 462, which is fixedly connected to the left end of the rectangular block 44.

[0053] In the above, by controlling the cylinder 452, the cylinder 452 drives the top plate 451 to slide upward at the left end of the rectangular block 44, so that the top plate 451 lifts the raw material.

[0054] In the above, the contact surface between the top plate 451 and the raw material is designed with an incline, so that when the top plate 451 lifts the raw material, the raw material will slide forward and keep the raw material in a horizontal state.

[0055] In the above process, the stepper motor 461 is started to rotate, and the stepper motor 461 then drives the steering gear 462 to rotate, so that the steering gear 462 transmits power to the drive shaft 10 located at the front, thereby driving the drive shaft 10 at the front to rotate.

[0056] It should be noted that the specific installation methods, circuit connection methods, and control methods of the operating table 1, power distribution box 2, laser tube cutting machine 7, servo motor 42, pneumatic clamping device 63, stepper motor 461, and cylinder 452 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
