When the upper die 8 moves downwards and is not sleeved on the permanent magnet rod 13, the permanent magnet rod 13 can continue to rotate due to inertia, the release agent in the liquid collecting cavity 15 is easy to throw out along the pipeline of the moving rod 16 under the action of centrifugal force, when the mounting plate 7 moves upwards, the mounting plate 7 drives the first gear 21 to rotate, the first gear 21 rotates anticlockwise, finally the extrusion head 22 extrudes the stressed rod 23, the stressed rod 23 moves leftwards and pushes the first conductive block 24, the first conductive block 24 moves leftwards and extrudes the elastic sheet 26, meanwhile, the electromagnet 27 is not contacted with the two groups of second conductive blocks 25 any more, at the moment, the electromagnet 27 loses magnetism, the electromagnet 27 does not magnetically attract the permanent magnet rod 13 any more, and when the upper die 8 rotates, the permanent magnet rod 13 can be driven to rotate through attraction between magnetism.
When the hydraulic press 6 pushes the mounting plate 7 to move downwards, the mounting plate 7 drives the first gear 21 to rotate when moving downwards, the first gear 21 rotates clockwise, the extrusion head 22 does not extrude the stressed rod 23 any more, the elastic sheet 26 pushes the first conductive block 24 to move to the right side, and finally the upper end and the lower end of the first conductive block 24 are contacted with the second conductive block 25, at the moment, the electromagnet 27 generates magnetism and attracts the permanent magnet rod 13 magnetically, and magnetic braking is realized under the action of the magnetic force, so that the rotation of the permanent magnet rod 13 is stopped rapidly.

As shown in fig. 1 and 2, a chute 36 is formed on the upper end surface of the bottom plate 1, the movable seat 2 is disposed in the chute 36, an air cylinder 37 is fixedly mounted at the bottom of the chute 36 near the left end, and the right end of the air cylinder 37 is fixedly connected with the movable seat 2.
When the eccentric reducing pipe is required to be manufactured, the cylinder 37 pushes the movable seat 2 to move rightwards when the upper die 8 performs reducing work on the blank steel pipe, so that the lower die 3 is driven to move, and the circle center of the reducing is dislocated with the circle center of the lower end of the steel pipe in the moving process, so that the eccentric reducing pipe is manufactured.
Working principle: after the machining is finished, the hydraulic press 6 controls the mounting plate 7 to move upwards, the upper die 8 leaves the machined reducing pipe, along with the continuous upward movement of the mounting plate 7, finally the permanent magnet rod 13 is inserted into the upper die 8 through the through hole 12, at the moment, the upper die 8 drives the permanent magnet rod 13 to rotate through magnetic attraction force when rotating, the permanent magnet rod 13 applies centrifugal force to the moving rod 16 when rotating, finally the moving rod 16 moves towards the outside of the liquid collecting cavity 15, meanwhile, the limiting block 41 presses the first spring 17, the sponge 18 is abutted against the inner wall of the upper die 8, and because the friction force for movement exists between the sponge 18 and the inner wall of the upper die 8, the rotation speed of the upper die 8 is larger than that of the permanent magnet rod 13 when rotating, and in order to avoid the fact that the permanent magnet rod 13 rotates at the same speed as the upper die 8, a friction block can be arranged at the position of the lower surface of the upper die 5, which is close to the permanent magnet rod 13, so as to reduce the speed of the permanent magnet rod 13; the release agent is filled in the liquid storage tank 10, the release agent can enter the liquid guide cavity 14 along the liquid discharge pipe 11 and finally enter the liquid collecting cavity 15, liquid in the liquid collecting cavity 15 is also helpful to flow to the outside along the inner wall of the moving rod 16 under the action of centrifugal force, and finally the sponge 18 is soaked, the sponge 18 rotates along with the inner wall of the upper die 8 in the upward moving process of the upper die 8, so that the release agent is smeared on the inner wall of the upper die 8, when the sponge 18 moves to the position, close to the lower end, of the inner wall of the upper die 8, the hydraulic press 6 pushes the upper flat plate 5 to move downwards, downward stamping operation is realized, and at the moment, the sponge 18 smears the upper die 8 from bottom to top, so that twice smearing of the release agent is facilitated, and further, the release agent can be smeared on the inner wall of the upper die 8 uniformly, and the release agent after later stamping is facilitated.
When the mounting plate 7 moves upwards, the mounting plate 7 drives the first gear 21 to rotate, the first gear 21 rotates anticlockwise, finally the extrusion head 22 extrudes the stressed rod 23, the stressed rod 23 moves leftwards and pushes the first conductive block 24, the first conductive block 24 extrudes the elastic sheet 26 when moving leftwards and is not contacted with the two groups of second conductive blocks 25 any more, at the moment, the electromagnet 27 loses magnetism, the electromagnet 27 does not magnetically attract the permanent magnet rod 13 any more, and the upper die 8 can drive the permanent magnet rod 13 to rotate through the attraction between magnetism during rotation; when the hydraulic press 6 pushes the mounting plate 7 to move downwards, the mounting plate 7 drives the first gear 21 to rotate when moving downwards, the first gear 21 rotates clockwise, the extrusion head 22 does not extrude the stressed rod 23 any more, the elastic sheet 26 pushes the first conductive block 24 to move to the right side, and finally the upper end and the lower end of the first conductive block 24 are contacted with the second conductive block 25, at the moment, the electromagnet 27 generates magnetism and attracts the permanent magnet rod 13 magnetically, and magnetic braking is realized under the action of the magnetic force.
In addition, when the permanent magnet rod 13 rotates, under the action of centrifugal force, the sealing ball 29 moves leftwards and compresses the second spring 28, at this time, the liquid leakage hole on the liquid leakage cover 30 is opened, the release agent can flow out from the liquid leakage hole, the sponge 18 is soaked finally, when the permanent magnet rod 13 stops rotating, the centrifugal force disappears, the second spring 28 pushes the sealing ball 29 to move rightwards, and finally, the sealing ball 29 can block the liquid leakage hole on the liquid leakage cover 30, so that the release agent can be prevented from flowing out from the moving rod 16 under the action of gravity.
The above description is only of the preferred embodiments of the present invention; the scope of the invention is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present invention, and the technical solution and the improvement thereof are all covered by the protection scope of the present invention.
