[0002] A special large air nozzle is a valve device used to control the flow of gas. In the current special large air nozzle manufacturing process, four special large air nozzles are usually connected together.

A clamping frame 31 is movably mounted on the workpiece frame 3, and a clamping guide rail 32 is mounted on the clamping frame 31. A group of clamping guide blocks 33 are slidably mounted on the clamping guide blocks 33, and clamping arms 34 are mounted on the opposite surfaces of the clamping arms 34, and the clamping plates 35 are arranged opposite to each other. When the four special large air nozzles connected as one are sheared and separated, the clamping arm 34 moves along the clamping guide rail 32 so that the clamping plates 35 clamp the workpiece to be sheared. Then the clamping frame 31 moves to drive the workpiece to be sheared to between the left shearing knife 21 and the right shearing knife 22, the left knife holder 213 moves to drive the left shearing knife 21, and the right knife holder 223 moves to drive the right shearing knife 22, so that the left shearing knife 21 and the right shearing knife 22 can shear and separate the workpiece to be sheared. This reduces the need for operators to use the cutter to perform shearing operations personally, and reduces the labor intensity of separating the Tean air nozzle.

[0035] In order to move the left shear blade 21 and the right shear blade 22, refer to Figure 2 and Figure 3, the piston cylinder 8 is installed on the shear frame 2, and the left piston head 211 and the right piston head 221 are slidably arranged in the piston cylinder 8. The left piston rod 212 is installed at the end of the left piston head 211 away from the right piston head 221, and the end of the left piston rod 212 away from the left piston head 211 penetrates the end wall of the piston cylinder 8, and the end of the left piston rod 212 located outside the piston cylinder 8 is welded to the left tool holder 213. The right piston rod 222 is installed at the end of the right piston head 221 away from the left piston head 211, and the end of the right piston rod 222 away from the right piston head 221 penetrates the end wall of the other end of the piston cylinder 8, and the end of the right piston head 221 located outside the piston cylinder 8 is welded to the right tool holder 223. The middle cavity 83 is between the left piston head 211 and the right piston head 221, and the end of the left piston head 211 away from the right piston head 221 is the left chamber 81, and the end of the right piston head 221 away from the left piston head 211 is the right chamber 82. The left chamber 81 is connected with the left output pipe 813 and the left input pipe 811, the left output valve 814 is installed on the left output pipe 813, and the left input valve 812 is installed on the left input pipe 811. The right chamber 82 is connected with the right output pipe 823 and the right input pipe 821, the right output valve 824 is installed on the right output pipe 823, and the right input valve 822 is installed on the right input pipe 821. The middle chamber 83 is connected with the input pump 831 and the output pump 832, the left output pipe 813 and the right output pipe 823 are both connected with the input end of the input pump 831, and the left input pipe 811 and the right input pipe 821 are both connected with the output end of the output pump 832. When the workpiece to be sheared moves between the left shearing knife 21 and the right shearing knife 22, the output pump 832 is started and the input pump 831 is stopped, the left input valve 812 and the right input valve 822 are opened, and the left output valve 814 and the right output valve 824 are closed. At this time, the filling medium in the middle cavity 83 is discharged, and the filling medium enters the left chamber 81 through the left input pipe 811, thereby pushing the left piston head 211 to approach the right piston head 221; the filling medium enters the right chamber 82 through the right input pipe 821, thereby pushing the right piston head 221 to approach the left piston head 211. The left piston head 211 and the right piston head 221 approach each other, so that the left piston rod 212 and the right piston rod 222 approach each other, the left piston rod 212 drives the left tool holder 213 to move, the movement of the left tool holder 213 drives the left shearing knife 21 to move, the right piston rod 222 drives the right tool holder 223 to move, the movement of the right tool holder 223 drives the right shearing knife 22, and then the left shearing knife 21 and the right shearing knife 22 approach each other to shear and separate the workpiece to be sheared. When the left shearing knife 21 and the right shearing knife 22 complete shearing of the workpiece, the output pump 832 stops and the input pump 831 starts, the left input valve 812 and the right input valve 822 are closed, and the left output valve 814 and the right output valve 824 are opened.At this time, the filling medium in the left chamber 81 is discharged into the middle chamber 83 through the left output pipe 813, and the filling medium in the right chamber 82 is discharged into the middle chamber 83 through the right output pipe 823, thereby making the left piston head 211 and the right piston head 221 move away from each other, and then making the left shearing knife 21 and the right shearing knife 22 move away from each other to wait for the next workpiece to be sheared.

When the clamping piece 35 is to be relatively moved, the clamping motor 4 is started to rotate the clamping rod 41, and the rotation of the clamping rod 41 drives the clamping shaft 42 to rotate with the motor output shaft as the axis, so that the clamping shaft 42 drives the clamping block 43 to move. On the one hand, the clamping block 43 moves in the height direction along the clamping slot 44, and on the other hand, the clamping block 43 drives the clamping arm 34 to move in the horizontal direction along the clamping guide rail 32, so as to achieve the effect that the clamping arm 34 drives the clamping piece to move relatively.

The longitudinal screw 73 is rotatably installed in the longitudinal groove 71, and the longitudinal screw 73 is threadedly connected with the longitudinal block 72. When the longitudinal motor 74 drives the longitudinal screw 73 to rotate, the longitudinal block 72 moves along the longitudinal groove 71, and the longitudinal block 72 drives the clamping frame 31 to move along the length direction. When the transverse motor 64 drives the transverse screw 63 to rotate, the transverse block 62 moves along the transverse groove 61, and the transverse block 62 drives the longitudinal seat 7 to move along the width direction, and the longitudinal seat 7 drives the clamping frame 31 to move along the width direction. When the vertical motor 513 drives the vertical screw 512 to rotate, the vertical block 511 moves along the vertical groove 51, and the vertical block 511 drives the transverse seat 6 to move along the height direction.

[0038] The implementation principle of the automatic separation device of a special safety large air nozzle in the embodiment of the present application is as follows: when shearing and separating four special safety large air nozzles connected in one, the workpiece to be processed is placed between the clamping pieces 35, and then the clamping motor 4 is started to clamp the workpiece to be sheared by the clamping piece 35. After that, the vertical motor 513, the horizontal motor 64 and the longitudinal motor 74 are started in coordination, so that the clamping frame 31 drives the workpiece to be sheared to move. When the workpiece to be sheared moves between the left shearing knife 21 and the right shearing knife 22, the output pump 832 is started and the input pump 831 is stopped, and the left input valve 812 and the right input valve 822 are opened, so that the left shearing knife 21 and the right shearing knife 22 are brought close to each other to shear and separate the workpiece to be sheared; when the left shearing knife 21 and the right shearing knife 22 have completed shearing the workpiece, the output pump 832 is stopped and the input pump 831 is started, and the left input valve 812 and the right input valve 822 are closed, so that the left shearing knife 21 and the right shearing knife 22 are moved away from each other to wait for the next workpiece to be sheared.
