When the lower part of the movable rod 240 contacts the frame 110, the movable rod 240 is blocked and keeps the current position, and the lifting rod 230 continues to descend. The lifting rod 230 slides relative to the movable rod 240, and the movable rod 240 and the driving rod 250 move upward relative to the lifting rod 230. The second spring 290 is compressed. When the central axis 234 in the middle of the lifting rod 230 contacts the upper part of the driving rod 250, the lifting rod 230 continues to descend, and the central axis 234 presses the driving rod 250 downward, the first spring 280 is compressed, and the driving rod 250 drives 160 to move toward the middle of the frame 110, and the insertion rod 262 is inserted into the middle of the seamless steel pipe. At the same time, the positioning pin 320 slides through the No. 2 waist groove 243, and the positioning pin 320 is inserted into the No. 2 waist groove 243. At this time, the swing rod 220 stops rotating and starts to rotate in the opposite direction, and the lifting rod 230 starts to rise.

After the swing rod 220 rotates in the opposite direction, it drives the seamless steel pipe to rise together. When the swing rod 220 drives the lifting rod 230 to move to the transverse groove of the driving groove 212, the seamless steel pipe is driven to the top of the conveyor belt 140. At this time, the positioning pin rod 321 contacts the inclined surface 214, and the inclined surface 214 fixes the three The No. 2 spring 330 is driven outward, the positioning pin 320 is pulled out of the No. 2 waist groove 243, the movable rod 240 and the driving rod 250 are reset under the action of the No. 2 spring 290 and the No. 1 spring 280 respectively, the material picking rod 260 is reset, and the seamless steel pipe is placed in the conveyor belt 140, completing a material picking and discharging action with accurate action, stable operation, and effective cooperation with the laser cutting machine. It can prevent vibration from being transmitted to the laser cutting area, causing relative vibration between the cutting head and the steel pipe, which will cause burrs on the cutting edge. Because of the vibration, the slag in the cutting process cannot be discharged smoothly, and solidifies at the edge to form burrs, and also causes a corrugated uneven surface on the cut section.

[0032] The invention discloses an operating method of a seamless steel pipe production cutting auxiliary device. When using the device, the seamless steel pipe is placed in a material frame 111 of a frame 110, and a lead screw 130 is rotated so that the gap between a baffle 120 and the bottom of the material frame 111 is slightly larger than the size of the seamless steel pipe. The cylinder 150 is started, and the cylinder 150 pushes the bottom layer of the seamless steel pipe in the material frame 111 to the left side of a bracket 113. The thrust of the cylinder 150 is adjusted to a suitable size, which ensures that the seamless steel pipe is pushed out without causing excessive pressure, so that each time a seamless steel pipe is taken out, the cylinder automatically pushes the seamless steel pipe forward. When the bottom layer of seamless steel pipes is taken out, the cylinder 150 is reset and the second layer of the seamless steel pipe is pushed out. After the seamless steel pipe is pushed out, the motor connected to the swing arm 220 is started. The motor adopts a servo motor. The forward and reverse angles are fixed. When taking materials, the swing arm 220 drives the lifting rod 230 to move to the left side of the bracket 113. After the lifting rod 230 moves to the upper part of the seamless steel pipe, the lifting rod 230 moves downward, and the insertion rods 262 on both sides are inserted into the middle of the seamless steel pipe. Then the swing arm 220 reverses, and the two material-taking rods 260 take away the seamless steel pipe, and the seamless steel pipe is driven above the conveyor belt 140. At this time, the positioning pin rod 321 contacts the inclined surface 214, and the inclined surface 214 drives the No. 3 spring 330 outward, and the positioning pin 320 is pulled out from the No. 2 waist groove 243. The movable rod 240 and the driving rod 250 are reset under the action of the No. 2 spring 290 and the No. 1 spring 280 respectively, and the material-taking rod 260 is reset, and the seamless steel pipe is placed in the conveyor belt 140, completing a material taking and discharging action.

[0033] The transfer plate 210, the swing arm 220, the lifting rod 230, and the moving block 270 cooperate with each other to enable the feeding rod 260 to switch between the feeding position and the discharging position of the seamless steel pipe. When the swing arm 220 drives the lifting rod 230 to rotate to the left side of the bracket 113 and the lower part of the movable rod 240 is not in contact with the frame 110, the movable rod 240 is at the bottom of the lifting rod 230 under the action of the No. 2 spring 290, and the driving rod 250 is at the top of the movable rod 240 under the action of the No. 1 spring 280. The feeding rod 260 is at the side closest to the movable rod 240 under the action of the driving rod 250. The distance between the feeding rods 260 on both sides is greater than the length of the seamless steel pipe. When the lower part of the movable rod 240 After contacting the frame 110, the insertion rod 262 is aligned with the lower position of the middle hole of the seamless steel pipe. Regardless of the size and shape of the seamless steel pipe, the insertion rod 262 will align with the lower position of the middle hole of the seamless steel pipe, which has strong adaptability. When the lower part of the movable rod 240 contacts the frame 110, the movable rod 240 is blocked and keeps the current position unchanged, and the lifting rod 230 continues to descend. The lifting rod 230 slides relative to the movable rod 240, and the movable rod 240 and the driving rod 250 move upward relative to the lifting rod 230. The second spring 290 is compressed. When the central axis 234 in the middle of the lifting rod 230 contacts the upper part of the driving rod 250, the lifting rod 230 continues to descend, and the central axis 234 drives the lifting rod 230 to move upward. The movable rod 250 is pressed downward, the No. 1 spring 280 is compressed, the driving rod 250 drives 160 to move toward the middle of the frame 110, the insertion rod 262 is inserted into the middle of the seamless steel pipe, and at the same time, the positioning pin 320 slides through the No. 2 waist groove 243, and the positioning pin 320 is inserted into the No. 2 waist groove 243. At this time, the swing rod 220 stops rotating and starts to rotate in the opposite direction, and the lifting rod 230 starts to rise. Since the positioning pin 320 is inserted into the No. 2 waist groove 243, the positioning pin 320 fixes the position of the driving rod 250 and the movable rod 240 relative to the lifting rod 230, and the material picking rod 260 will not reset. After the swing rod 220 rotates in the opposite direction, it drives the seamless steel pipe to rise together. When the swing rod 220 drives the lifting rod 230 to move After moving to the transverse groove of the driving groove 212, the seamless steel pipe is driven to the top of the conveyor belt 140. At this time, the positioning pin rod 321 contacts the inclined surface 214, and the inclined surface 214 drives the No. 3 spring 330 outward. The positioning pin 320 is pulled out from the No. 2 waist groove 243, and the movable rod 240 and the driving rod 250 are reset under the action of the No. 2 spring 290 and the No. 1 spring 280 respectively. The material picking rod 260 is reset, and the seamless steel pipe is placed in the conveyor belt 140, completing the automatic material picking and discharging actions, effectively cooperating with the laser cutting machine to work, with accurate action and stable operation, to prevent the speed from being set too fast, the laser beam will heat and melt the surface of the steel pipe unevenly, thereby affecting the flatness of the cutting surface.
