Referring to fig. 5, when the automatic production line works, firstly, a drill rod blank 11 is put into a drill rod blank bin 10, a control electric box 1 and a hydraulic workstation 17 are started, the state of a numerical control lathe 3 is adjusted, and a drill rod machining program with corresponding specification is called. And checking and replacing the model and the state of the machining tool at each station on the numerical control tool rest of the machine tool. The numerical control lathe 3 is in a standby state, and the whole system is started to start working. Firstly, a drill rod blank bin 10 is started, and the drill rod blank bin 10 consists of a swing bin plate 10-A, a screw rod fixing pin shaft 10-B, a motor 10-C, a reduction gearbox 10-D, a transmission screw rod II 10-E, a drill rod blank bin frame 10-F, a swing bin plate pin shaft 10-G, a drill rod blank guard plate 10-H and a fixing stop lever 10-P.
The drill rod blank bin 10 is positioned at the middle and back position of the two numerical control lathes 3 and is adjacent to the discharging material bed 9. The drill rod blank bin frame 10-F is fixed on the ground, and a swing bin plate 10-A is installed on the drill rod blank bin frame. The swing bin plate 10-A forms a revolute pair through the bracket and the swing bin plate pin shaft 10-G, so that the swing bin plate 10-A can swing up and down around the swing bin plate pin shaft 10-G. The swing power is provided by a motor 10-C, and is transmitted to a swing bin plate 10-A through a reduction gearbox 10-D and a transmission screw rod II 10-E, wherein the swing bin plate 10-A consists of a screw rod fixing pin shaft 10-B and the transmission screw rod II 10-E to form a rotating pair. The reduction gearbox 10-D is fixed on the drill rod blank bin frame 10-F. The drill rod blank bin frame 10-F is also fixed with a drill rod blank guard plate 10-H and a fixed stop lever 10-P, and the movement track of the drill rod blank 11 is restrained on the drill rod blank guard plate.
When the drill rod blanks 11 are put into the drill rod blank storage bin 10, the swing bin plate 10-A is inclined downwards, the drill rod blanks 11 are loosely piled up above the swing bin plate 10-A, and when the pile reaches a certain height, the redundant drill rod blanks 11 gradually roll down to the discharge material bed 9 under the action of dead weight, and the discharge material bed 9 is fully discharged by the drill rod blanks 11. The machine is started to start working and the number of drill rod blanks 11 on the bed starts to decrease. When the number of the drill rod blanks 11 on the discharging material bed 9 is reduced to a certain number, the position control detection switch 21 sends out a signal, the motor 10-C is started, power is transmitted to the transmission screw rod II 10-E through the reduction gearbox 10-D, the swing bin plate 10-A is driven to swing upwards, the pile of the drill rod blanks 11 is gradually lifted, and the drill rod blanks 11 gradually roll down onto the discharging material bed 9 under the action of dead weight until the discharging material bed 9 is full. Upon receipt of the discharge bed 9 full signal, the motor 10-C is stopped. And (3) machining by a numerical control lathe. The above is then repeated until the rod blank magazine 10 is completely emptied, the position control detection switch 21 signals the swing magazine plate 10-a to resume its original state and prompt the operator to timely replenish the rod blank 11.
Referring to fig. 11 and 12, the discharge bed is composed of a discharge bed main body 9-a and a blank detection mechanism provided on the discharge bed main body 9-a, the blank detection mechanism comprising a guide rail 9-B, a blank sensing detection plate 9-C, a compression spring 9-D, a guide circular guide rail 9-E, a guide bush 9-F, and the like.
The discharge bed 9 is adjacent to the drill pipe blank magazine 10 and is located in front of the drill pipe blank magazine 10. The blank induction detection plate 9-C and the guide circular guide rail 9-E are connected into a whole through screws, a sliding pair is formed by the blank induction detection plate and the guide sleeve II 9-E, the guide sleeve II 9-F is fixed on the discharging material bed main body 9-A through a circular nut, three sets of compression springs 9-D are uniformly distributed around the guide circular guide rail 9-E, the upper ends of the compression springs 9-D are in contact with the detection plate 9-C, the lower ends of the compression springs 9-D are in contact with the discharging material bed main body 9-A, and the left and right positions of the compression springs 9-D are limited by pin shafts fixed on the discharging material bed main body 9-A. The guide rail 9-B is located at the forefront and is responsible for guiding the drill rod blank 11 into the drill rod blank adjustment device 20.
When the drill rod blanks 11 roll on the discharging material bed 9, the inclined guide surfaces with the angle of about 3 degrees roll forwards along the upper surface of the discharging material bed 9, so that the drill rod blanks 11 are arranged next to one another near one end of the drill rod blank pushing device 8, when the discharging material bed 9 is fully discharged by the drill rod blanks 11, the drill rods stay on the blank sensing detection plates 9-C, the compression springs 9-D are compressed under the stress, the blank sensing detection plates 9-C and the guide circular guide rails 9-E move downwards, the position control detection switches 21 are close to the position control detection switches 21, and the position control detection switches 21 send control signals to control the actions of the drill rod blank bins 10.
The front end of the discharging material bed 9 is provided with a drill rod blank pushing device 8, and the drill rod blank pushing device 8 consists of a short pushing iron 8-A, a long pushing iron 8-B, a blank pushing iron guide rail 8-C, a short pushing iron pushing oil cylinder 8-D, a long pushing iron pushing oil cylinder 8-E and a pushing oil cylinder fixing hinge 8-F.
The two pushing oil cylinder fixing hinges 8-F are respectively fixed on the discharging material bed main body 9-A and are hinged with the oil cylinder bodies of the short pushing iron pushing oil cylinder 8-D and the long pushing iron pushing oil cylinder 8-E through pin shafts.

The short push iron pushing cylinder 8-D and the long push iron pushing cylinder 8-E are started simultaneously to push the short push iron 8-A and the long push iron 8-B to move upwards and sideways along the blank push iron guide rail 8-C, the short push iron 8-A and the long push iron 8-B are obliquely arranged at an inclination angle of about 20 degrees with the horizontal plane, and referring to fig. 13, the top of the short push iron 8-A and the side surface of the long push iron 8-B form a V-shaped structure I together, and the structure can support the drill rod blank 11. Since the width of the short push iron 8-a is slightly narrower than the diameter of the drill rod blank 11, this V-shaped configuration i can only accommodate 1 drill rod blank 11 at a time. After the oil cylinder stops waiting for a period of time when reaching the end of the stroke, the long push iron pushing oil cylinder 8-E retracts, at the moment, the top ends of the short push iron 8-A and the long push iron 8-B are positioned on the same plane, and as the inclination angle of about 20 degrees exists between the plane and the horizontal plane, the drill rod blank 11 positioned at the top end of the short push iron 8-A rolls to the top end of the long push iron 8-B under the action of dead weight and stops in another V-shaped structure II formed by the top end of the long push iron 8-B and the push iron guide rail 8-C. The short push iron push ram 8-D is then retracted and the drill rod blank 11 on the discharge bed 9 rolls along the inclined guide surface, the foremost drill rod blank 11 stopping adjacent the long push iron 8-B side. The short push iron pushing oil cylinder 8-D and the long push iron pushing oil cylinder 8-E are started again and simultaneously, the short push iron 8-A and the long push iron 8-B are pushed to move upwards and sideways along the blank push iron guiding guide rail 8-C, the oil cylinders stop when reaching the stroke end, and the top of the long push iron 8-B is flush with the blank discharging material bed guiding rail 9-B. The drill rod blank 11 at the top of the long push iron 8-B rolls down the guide rail 9-B under its own weight onto the drill rod blank adjustment device 20. The long push iron push cylinder 8-E is retracted and the drill rod blank 11 in the V-shaped structure I rolls into the V-shaped structure II, the short push iron 8-A is retracted, and the V-shaped structure I receives the next drill rod blank 11.
