Similarly, on the second transmission shaft 121 and the second sleeve shaft 122, the tightening assembly 14 also pushes the second sleeve shaft 122 to the second transmission shaft 121 in a limited manner when the second telescopic assembly 123 is in a stretched state, that is, the lower press roll 12 is in a use state, and when the second telescopic assembly 123 is reset, the tightening assembly 14 in the second transmission shaft 121 breaks away from the limitation of the second sleeve shaft 122, that is, the second sleeve shaft 122 is in a loose state.

It should be noted that, one end of the connecting rod 141 is rotatably connected to the connecting shaft 117, and in order to reduce friction, the rotating fit portion may be provided with balls to replace sliding fit by rolling fit, that is, the connecting rod 141 may rotate at one end of the connecting shaft 117, and when the first transmission shaft 111 and the second transmission shaft 121 rotate, the connecting shaft 117 rotates synchronously along with the first transmission shaft 111 or the second transmission shaft 121 by using the above rotating connection.

In another embodiment of the present invention, further, the first set of shafts 112 and the second set of shafts 122 each include an inner shaft 16 and an outer shaft 15, with the inner shaft 16 being detachably connected to the outer shaft 15.

Specifically, the outer shaft 15 is sleeved on the outer wall of the inner shaft 16, the sliding block 113 is mounted on the inner shaft 16 and is connected to the inner shaft 16 in a radial sliding manner, the inner wall of the outer shaft 15 is provided with a containing groove 151, the containing groove 151 is radially provided with a second wedge block 152 and a first spring 153, one end of the first spring 153 is connected with the groove wall of the containing groove 151, the other end of the first spring 153 is connected with the second wedge block 152, the outer wall of the inner shaft 16 is provided with a clamping groove 161 matched with the second wedge block 152, the second wedge block 152 and the clamping groove 161 form a limiting interference fit, the sliding block 113 is slidingly connected to the inner shaft 16, the inner shaft 16 is provided with a perforation, the sliding block 113 penetrates through the perforation and is slidingly connected to the inner shaft 16, the inside of the perforation is provided with a second spring 162, one end of the second spring 162 is connected with the inner wall of the inner shaft 16, one end of the sliding block 113 close to the outer shaft 15 is integrally formed with a limiting block 114, the inner wall of the outer shaft 15 is provided with a limiting groove 154, the limiting groove 154 corresponds to the perforation, the limiting block 114 and the limiting groove 154 forms a limiting interference fit with the limiting groove 154,

Taking the first transmission shaft 111 and the first sleeve shaft 112 as an example, when the upper press roll 11 is in a use state, the first wedge block 142 forces the sliding block 113 to move radially, the second spring 162 stretches, the sliding block 113 moves to drive the limiting block 114 on the sliding block 113 to enter the limiting groove 154 and form limiting interference fit with the limiting groove 154, so that although the outer shaft 15 is sleeved on the inner shaft 16, the outer shaft 15 cannot rotate and slide on the inner shaft 16 under the limiting action of the limiting block 114, the inner shaft 16 and the outer shaft 15 form a whole, in this state, the inner shaft 16 and the outer shaft 15 synchronously follow the rotation of the first transmission shaft 111, namely rolling treatment of metal blanks is realized, when the upper press roll 11 is in a disassembly state, namely the first transmission shaft 111 and the first sleeve shaft 112 are both rotated to be in a vertical state, the sliding block 113 and the second wedge block 152 are also in a vertical state, and at the moment, the first telescopic component 116 is reset to drive the first wedge block 142 to be separated from the interference with the sliding block 113, the second spring 162 is reset to shrink, the sliding block 113 is driven to slide in the inner shaft 16, and the reset limiting block 114 is driven to extend from the limiting groove 154, namely the limiting block 114 moves from the inner shaft 16 to the limiting block 16, namely, the outer shaft 114 moves from the inner shaft 114 to the limiting block 15 to the inner shaft 15 to the limiting shaft 15 to extend from the limiting groove 114 to the inner shaft 15 to the limiting groove 15;

However, the inclined surface of the second wedge 152 is close to one side surface of the inner shaft 16 and is not two end surfaces in the length direction, the length direction of the second wedge 152 is consistent with the axial direction of the inner shaft 16 and the outer shaft 15, the length of the second wedge 152 is slightly smaller than the length of the clamping groove 161, so when the inner shaft 16 and the outer shaft 15 are in a vertical state, the outer shaft 15 slightly descends a section under the influence of gravity after losing the limit of the limiting block 114, the side groove wall of the clamping groove 161 is abutted against the lower end surface of the second wedge 152 in the vertical state, the lower end surface, namely the horizontal surface, is abutted against the clamping groove 161, and the second wedge 152 is not retracted into the accommodating groove 151, so that although the limiting block 114 is separated from the limiting groove 154, the outer shaft 15 cannot slide on the inner shaft 16 in the vertical state, and therefore when the first transmission shaft is not bent at all, the outer shaft is lifted vertically, the outer shaft 15 is lifted vertically, the second wedge 152 is firstly driven to move along the groove of the clamping groove 161, the upper end surface of the second wedge 152 is abutted against the other side groove wall of the clamping groove 161, the side surface of the second wedge 152 is synchronously driven by the second wedge 152, the sliding block 113 is synchronously driven by the second wedge 152 under the action of the second wedge 152, the sliding block 113 is separated from the sliding groove 115, and the second wedge 113 is also removed from the first shaft 113 and the second wedge 111, and is dismounted from the first shaft 111;

When the first transmission shaft 111 is slightly bent under the long-term use, in the disassembly state, the sliding groove 115 is bent due to the bending influence of the first transmission shaft 111, so that the sliding block 113 cannot slide smoothly along the groove direction in the sliding groove 115, at the moment, in the disassembly process of the inner shaft 16 and the outer shaft 15, the limit of the limit block 114 is lost between the inner shaft 16 and the outer shaft 15 because the limit block 114 is separated from the limit groove 154 along with the radial reset of the sliding block 113, so that a worker can rotate the outer shaft 15, the inner shaft 16 is kept stationary under the limit of the sliding block 113, the inner shaft 16 and the outer shaft 15 relatively rotate, the rotation of the outer shaft 15 drives the second wedge 152 to synchronously rotate, the inclined surface on the side surface of the second wedge 152 is contacted with the groove wall of the clamping groove 161 in the rotation process, the second wedge 152 is forced to retract into the accommodating groove 151 under the interference of the inner shaft 16, the second wedge 152 is separated from the inner shaft of the clamping groove 161, at the moment, the limit between the outer shaft 15 and the inner shaft 16 is released, the outer shaft 15 can slide on the inner shaft 16 and the first transmission shaft 111, namely the outer shaft 15 can be removed from the inner shaft 16 and the inner shaft 16;

Secondly, the annular structure of the inner shaft 16 is composed of two groups of semicircular sector plates, and the two groups of sector plates are combined on the outer shaft 15 to form the inner shaft 16, so that after the outer shaft 15 is taken down from the inner shaft 16, the two groups of sector plates also lose the limitation of the outer shaft 15, and the two groups of sector plates are taken down directly along the radial direction of the first transmission shaft 111, at the moment, the inner shaft 16, namely the two groups of sector plates and the outer shaft 15, are taken down from the bent first transmission shaft 111, namely the first sleeve shaft 112 is taken down from the bent first transmission shaft 111, then the first sleeve shaft 112 is replaced, and meanwhile, the bent first transmission shaft 111 also needs to be replaced or maintained with great attention, so that the rolling precision of a metal blank is prevented from being influenced;

Similarly, since the second transmission shaft 121 and the first transmission shaft 111 have the same structure, the second sleeve shaft 122 and the first sleeve shaft 112 have the same structure, and thus can be removed from the bent second transmission shaft 121 according to the above steps.

In another embodiment of the present invention, a roll forming production line is further provided, including the roll forming mechanism described above, and further including a cutting mechanism and a conveying mechanism, where the conveying mechanism is used for conveying the metal blank cut by the cutting mechanism into the roll forming mechanism.
