[0015] The present invention provides a perforating extruder for producing nickel-based alloy seamless pipes. It has the following beneficial effects:

[0016] (1) The invention limits the position of the pipe by a limit plate and a support plate to prevent the pipe from moving when the pipe is pushed into the perforating and extruding device, resulting in uneven extrusion force and uneven shape and size of the pipe. At the same time, the downward movement of the sliding rod will drive the fixed plate to move downward, and the downward movement of the fixed plate will push one end of the rotating plate to rotate downward. The downward rotation of one end of the rotating plate will drive the other end of the rotating plate to rotate upward. The upward rotation of the other end of the rotating plate will push the rubber plate to move upward. The rubber plate moves upward and contacts with the pipe, and the friction between the two is increased by rubber, so as to prevent the pipe from rotating during the process of the push plate pushing the pipe. The rotation of the pipe will cause the perforation position to be unstable, so that the holes formed are irregular or of different sizes.

[0017] (2) The invention corrects the pipe by moving the pulley frame toward the middle of the processing table and supports the pipe at the same time. Supporting the pipe can ensure that it maintains a stable position and direction during the processing, thereby improving the accuracy of perforation. The air pressure plate moves toward the inside of the air pressure box to allow air to enter the air pressure box. When the fixed rod is separated from the triangular block, the elastic force of the spring drives the air pressure plate to reset. The air inside the air pressure box is ejected by the reset of the air pressure plate, and the impurities dropped from the pipe are blown into the recovery tank. There is no need for manual cleaning, thereby improving safety.

[0018] (3) The invention uses a brush on an elastic plate to scrape off impurities attached to the pipe to prevent the impurities from rubbing against the surface of the pipe during the perforation process and causing scratches, wear or pits on the surface of the pipe. At the same time, the long plate moves toward the middle of the processing table, which drives the L-shaped plate to move toward the middle of the processing table. The movement of the L-shaped plate toward the middle of the processing table drives the rotating rod to rotate. The rotation of the rotating rod drives the rotating rod to rotate upward. The bottom of the pipe is supported by the upward rotation of the rotating rod, so that the pipe is in the middle position when entering the perforation extrusion device, ensuring that the perforation is in the center of the pipe, thereby improving the accuracy of the perforation.

The limiting plate 11 is fixedly installed on the surface of the connecting plate 10, and the limiting plate 11 slides through the surface of the push plate 4. The pipe is limited by the limiting plate 11 and the support plate 5 to prevent the pipe from moving when the pipe is pushed into the perforating and extruding device 2, resulting in uneven extrusion force, which will make the shape and size of the pipe uneven.

[0029] A spring No. 1 is arranged between the sliding rod 7 and the support plate 5, and the sliding rod 7 is reset by the spring No. 1. The connecting plate 10 is arranged below the sliding rod 7. A reset spring is arranged between the sliding plate 9 and the push plate 4, and the sliding plate 9 is reset by the reset spring.

The downward rotation of one end of the rotating plate 12 will drive the other end of the rotating plate 12 to rotate upward. The upward rotation of the other end of the rotating plate 12 will push the rubber plate 14 to move upward. The rubber plate 14 moves upward and contacts with the pipe, and the friction between the two is increased by rubber to prevent the pipe from rotating during the process of the push plate 4 pushing the pipe. The rotation of the pipe will cause the perforation position to be unstable, so that the holes formed are irregular or of different sizes.

[0032] See also Figure 1-Figure 7On the basis of the above embodiment, another embodiment of the present invention further includes a correction device and a protection device. The correction device includes an L-shaped rod 151, a rotating wheel 152, a sliding frame 153, a sliding groove 154, an elastic telescopic rod 155 and a pulley frame 156.

[0035] The protective device includes a long plate 161, a rotating shaft 162, a rotating plate 163, an elastic telescopic plate 164 and an elastic plate 165. The long plate 161 is fixedly mounted on the surface of the sliding frame 153, the rotating shaft 162 is rotatably mounted on the surface of the perforating and extruding device 2, the rotating plate 163 is fixedly mounted on the circumferential surface of the rotating shaft 162, the elastic telescopic plate 164 is fixedly mounted on the surface of the rotating plate 163, and the elastic plate 165 is fixedly mounted on the free end of the elastic telescopic plate 164. The brush on the elastic plate 165 is used to scrape off impurities attached to the pipe to prevent the impurities from rubbing against the surface of the pipe during the perforation process, causing scratches, wear or pits on the surface of the pipe.

[0036] An L-shaped plate 166 is fixedly installed at the bottom of the long plate 161, and a rotating rod 167 is rotatably installed on the surface of the support plate 6. A rotating rod 168 is fixedly installed on the surface of the rotating rod 167. The rotating rod 168 is rotated upward to support the bottom of the pipe, so that the pipe is in the middle position when entering the perforating and extruding device 2, ensuring that the perforation is in the center of the pipe, thereby improving the accuracy of the perforation.

A brush is arranged on the surface of the elastic plate 165.

[0038] When the present embodiment is working, the push plate 4 moves toward the direction of the perforating and extruding device 2, driving the L-shaped rod 151 to move toward the direction of the perforating and extruding device 2. The L-shaped rod 151 moving toward the direction of the perforating and extruding device 2 will drive the rotating wheel 152 to move toward the direction of the perforating and extruding device 2. The rotating wheel 152 moving toward the direction of the perforating and extruding device 2 will contact the slide groove 154. The rotating wheel 152 will push the sliding frame 153 to move toward the middle of the processing table 1. The sliding frame 153 moving toward the middle of the processing table 1 will drive the elastic telescopic rod 155 to move toward the middle of the processing table 1. The elastic telescopic rod 155 moving toward the middle of the processing table 1 will drive the pulley frame 156 to move toward the middle of the processing table 1. The pulley frame 156 moves toward the middle of the processing table 1 to correct the pipe and support the pipe at the same time. Supporting the pipe can ensure that it maintains a stable position and direction during the processing, thereby improving the accuracy of the perforation. When the long plate 161 moves toward the direction close to the perforation and extrusion device 2, it will drive the fixed rod 158 to move toward the direction close to the perforation and extrusion device 2. The fixed rod 158 moves toward the direction close to the perforation and extrusion device 2 and contacts the inclined surface of the triangular block 1513. The fixed rod 158 will squeeze the triangular block 1513 and the connecting rod 1512 to move toward the inside of the air pressure box 157. The movement of the connecting rod 1512 toward the inside of the air pressure box 157 will drive the air pressure plate 1511 to move toward the inside of the air pressure box 157. The air pressure plate 1511 moves toward the inside of the air pressure box 157 so that air enters the inside of the air pressure box 157. When the fixed rod 158 is disengaged from the triangular block 1513, the elastic force of the spring 1510 itself drives the air pressure plate 1511 to reset. The air inside the air pressure box 157 is ejected through the reset of the air pressure plate 1511, and the impurities dropped on the pipe are blown into the recovery tank. No manual cleaning is required, thereby improving safety.

[0039] The pulley frame 156 moves toward the middle of the processing table 1, driving the long plate 161 to move toward the middle of the processing table 1. The movement of the long plate 161 toward the middle of the processing table 1 will push the rotating plate 163 to rotate toward the middle of the processing table 1. The rotation of the rotating plate 163 will drive the elastic expansion plate 164 to rotate. The rotation of the elastic expansion plate 164 will drive the elastic plate 165 to rotate. The elastic plate 165 rotates to contact the pipe, and the brush on the elastic plate 165 is used to scrape off the impurities attached to the pipe, so as to prevent the impurities from contacting the pipe surface during the perforation process. The surface friction causes scratches, wear or pits on the surface of the pipe. At the same time, the long plate 161 moves toward the middle of the processing table 1, which drives the L-shaped plate 166 to move toward the middle of the processing table 1. The L-shaped plate 166 moves toward the middle of the processing table 1 and pushes the rotating rod 167 to rotate. The rotation of the rotating rod 167 drives the rotating rod 168 to rotate upward. The bottom of the pipe is supported by the upward rotation of the rotating rod 168, so that the pipe is in the middle position when entering the perforating and extruding device 2, ensuring that the perforation is in the center of the pipe, thereby improving the accuracy of the perforation.
