A feeding device, a punching device, a chip removal device and a feeding device are sequentially arranged on the machine tool. The feeding device delivers the pipe fittings to the punching device, and the hydraulic cylinder pushes the punching tool down at the designated position and cooperates with the inner lining pipe to punch holes. A blower motor blows the waste chips generated by punching to the front table, and then the chip removal device sweeps back and forth on the table to absorb the waste chips. After the punching is completed, the feeding device pushes the finished pipe fittings to the front table, and under the action of the flipping mechanism, the pipe fittings are transported to the finished product box.

[0004] The above-mentioned prior art has the following technical problems: when the existing punching machine punches holes in hollow profiles, it is not convenient to effectively support the inner wall of the hollow profile, because the inner wall of the profile is hollow, and the punching is performed from the outside to the inside, which can easily cause deformation around the punching area of ​​the hollow profile, thereby affecting the normal use of the subsequent profile.

A support block 1510 is arranged above the accommodating column 159, and the middle rod body of the support block 1510 is inserted into the interior of the accommodating column 159. The middle rod body of the support block 1510 is connected to the accommodating column 159 through the built-in spring 1511. The guide drive roller 154 can rotate on the clamping frame 153 and the limiting tube 157, and the interior of the guide drive roller 154 is set as a hollow structure. The interior of the guide drive roller 154 and the limiting tube 157 are connected to each other, and the guide drive roller 154 is connected to the limiting tube 157. 54 can enter the interior of the accommodation column 159 through the limiting tube 157 and the circulation hose 158. A sealing ring is fixed to the circumference of one end of the piston rod 156 located inside the guide transmission roller 154, and the middle rod body of the piston rod 156 is threadedly connected to the inside of the rotating shaft on the guide transmission roller 154. The cross-section of the end of the piston rod 156 extending out of the guide transmission roller 154 is rectangular. The rectangular section on the piston rod 156 can slide on the clamping frame 153. Two support blocks 1510 are provided, and the rod bodies in the middle of the two support blocks 1510 form a seamless sliding connection structure with the accommodation column 159 through a fixed sealing ring.

[0031] When it is necessary to punch the C-profile, the mechanical clamping arm 14 is controlled by the moving adjustment module 13 to clamp the C-profile to be punched, and the mechanical clamping arm 14 places the clamped C-profile on the first carrying block 7 and the second carrying block 10. Then, after the first cylinder 8 is turned on, the positioning clamping block 9 can be used to clamp and fix the C-profile. Then, the third cylinder 152 is turned on. After the third cylinder 152 is turned on, the clamping frame 153 and the guide transmission roller 154 can contact the side of the C-profile to achieve auxiliary positioning of the C-profile and prevent the C-profile from deviating. The servo motor 3 is turned on. After the servo motor 3 is turned on, the guide screw 4 can be rotated. The rotation of the guide screw 4 can make the threaded movable table 5 move toward the direction of the punching die 12. The lower end of the movable platform 5 can move on the connecting guide rail 6, thereby preventing the movable platform 5 from rotating synchronously with the connecting guide rail 6, ensuring the stability of the movable platform 5 when moving. After the movable platform 5 moves, one end of the C-profile is extended into the punching die 12, and the C-profile can rotate the guide drive roller 154 that is fitted on the side when moving. After the guide drive roller 154 rotates, the threaded piston rod 156 can move downward. After the piston rod 156 moves below the guide drive roller 154, the airflow inside the guide drive roller 154 can be squeezed into the interior of the accommodating column 159 through the limiting tube 157 and the circulation hose 158, and the piston rod 156 inside the guide drive roller 154 is circumferentially fixed with a sealing ring. 6 circumferentially fixed sealing rings can ensure the sealing of the piston rod 156 when it moves inside the guide transmission roller 154, and prevent air leakage between the piston rod 156 and the inside of the guide transmission roller 154. At the same time, the cross-section of the upper end of the piston rod 156 is set to be rectangular. Through the movement of the rectangular section of the piston rod 156 on the clamping frame 153, the piston rod 156 can be prevented from rotating synchronously with the guide transmission roller 154. After the air flow inside the accommodating column 159 increases, the support block 1510 can be pushed to move upward, so that the support block 1510 supports the periphery of the C-profile punching area after it moves into place, and then the second cylinder 123 is turned on. After the second cylinder 123 is turned on, the movable platform 124 and the punching punch 124 fixed below can be moved upward. 5 moves downward, and the punching punch 125 automatically punches one end of the C-profile by moving downward, and the support block 1510 has supported the periphery of the punching area of ​​the C-profile, so as to avoid the internal hollowness of the C-profile, which causes the periphery of the punching area to be concave and deformed during punching. When one end of the C-profile is punched, the third cylinder 152 controls the clamping frame 153 and the guide drive roller 154 to separate from the side of the C-profile, and the guide drive roller 154 is reset and reversed under the action of the vortex spring 155. After the guide drive roller 154 is reset and reversed, the piston rod 156 threadedly connected is also reset and reversed. At this time, the airflow inside the accommodating column 159 flows back to the inside of the guide drive roller 154, and the support block 1510 is also reset and separated from the C-profile.Then the servo motor 3 controls the lead screw 4 to rotate in the opposite direction. After the lead screw 4 rotates in the opposite direction, the movable platform 5 drives the C-shaped material with one end punched to reset. Since two bearing plates 2 are installed on the fixed base 1, and the two bearing plates 2 and the components thereon are mirror images, the C-shaped material with one end punched is clamped by the mechanical clamp arm 14 again, so that the C-shaped material is placed on the second bearing plate 2. Then the same operation is repeated to realize the automatic punching of the double ends of the profile. After the double ends of the C-shaped material are punched, the mechanical clamp arm 14 is used to clamp and move the profile to the next station for subsequent processing.

[0032] Embodiment 2: The technical contents disclosed in this embodiment are further improvements made on the basis of the above-mentioned embodiment 1. The following technical contents are disclosed in this embodiment: a power rod 1512 is inserted into the support block 1510, and the power rod 1512 is connected to the support block 1510 through an auxiliary spring 1513, a side clamp 1514 is provided on the side of the support block 1510, and one end of the side clamp 1514 extending into the interior of the support block 1510 is fixedly connected with a force-bearing pressure block 1515, and the force-bearing pressure block 1515 is connected to the support block 1510 through a reset spring 1516, the power rod 1512 can slide on the support block 1510, and the inclined surface of the lower end side of the power rod 1512 fits with the inclined surface of the force-bearing pressure block 1515, and the force-bearing pressure block 1515 and the support block 1510 are slidably connected.

[0033] When the internal airflow of the accommodating column 159 increases, thereby pushing the support block 1510 to move upward, the support block 1510 can move upward to enable the power rod 1512 to move synchronously. After the power rod 1512 moves, it can contact the C-profile and move downward. The lower end side inclined surface of the power rod 1512 is in contact with the inclined surface of the force-bearing pressure block 1515. At this time, after the power rod 1512 moves downward, it can use the inclined edge to squeeze and push the force-bearing pressure block 1515. After the force-bearing pressure block 1515 moves, it can drive the side clamp 1514 to move synchronously. The side clamp 1514 moves toward the outside of the support block 1510 and then contacts and presses the inner side wall of the C-profile, thereby assisting in fixing the C-profile that is being punched and punched, thereby ensuring the stability of the C-profile during punching and punching.

[0034] In the prior art, when the profile is supported for stamping, a fixed support structure is usually set. Although the fixed support structure can play an auxiliary supporting role, when the C-profile is pushed, there is a large friction between the inner wall of the C-profile and the support structure. The large friction resistance easily causes the inner wall of the C-profile to wear, which affects the subsequent use of the C-profile. At the same time, when the friction resistance is too large, it also increases the force required for pushing the C-profile. In addition, the fixed support structure can only play a fixing role, and cannot play an auxiliary positioning role for the C-profile when the C-profile is punched and perforated. The overall functionality is single. In the present application, the C-profile is supported by the support block 1510. The support block 1510 does not contact the inner wall of the C-profile in the initial state, thereby avoiding the inner surface of the C-profile having a large friction with the support block 1510 when the C-profile is pushed, which causes the inner wall of the C-profile to wear. At the same time, after the guide drive roller 154 contacts the side wall of the C-profile, it can position the side of the C-profile to prevent the C-profile from offset when punching. At the same time, the rotation of the guide drive roller 154 after contacting the C-profile provides power to realize the movement of the support block 1510 and the subsequent support and fixation of the C-profile by the side clamp 1514, thereby reducing the use of redundant electrical equipment and the probability of wear on the inner wall of the C-profile.

[0035] Compared with the prior art, the present invention has the following beneficial effects: A first carrying block 7 is provided, and the C-shaped material placed by the mechanical clamping arm 14 can be supported by the first carrying block 7 and the second carrying block 10, and the C-shaped material is automatically clamped by the symmetrically distributed positioning clamping blocks 9, and the movable platform 5 pushes the fixed C-shaped material into the punching die 12 for automatic punching by the rotation of the lead screw 4; A support block 1510 is provided. After the guide drive roller 154 contacts the side of the C-profile, the C-profile is pushed to make the guide drive roller 154 rotate. The rotation of the guide drive roller 154 can move the piston rod 156 threadedly connected thereto. The movement of the piston rod 156 can transport the airflow inside the guide drive roller 154 to the inside of the accommodating column 159 through the limit tube 157 and the flow hose 158. The increase of the airflow inside the accommodating column 159 can push the support block 1510 to move upward. The upward movement of the two support blocks 1510 can support the periphery of the punching area of ​​the C-profile to avoid the punching pressure causing the C-profile punching area to be concave and deformed. A power rod 1512 is provided. When the support block 1510 moves upward, the power rod 1512 can move upward synchronously to contact the C-profile. When the power rod 1512 is pressed, it moves downward. After the power rod 1512 moves, it can utilize the interaction with the oblique edge of the force-bearing pressure block 1515 to push the force-bearing pressure block 1515 and the side clamp 1514 to move toward the outside direction of the support block 1510. After the support block 1510 moves outward, it contacts the inner wall of the C-profile, and then the C-profile that is punched and punched can be auxiliary fixed, thereby improving the stability of the C-profile during punching and punching, and preventing the C-profile from offsetting due to unstable fixation during punching, resulting in deviation in the punching position.
