The fixed key 301b-2 and the keyway 301b-4 cooperate to drive the movable cylinder 301b-1 to rotate in the mounting hole 301a-5, which is beneficial to reduce the friction force of the roller shaft 304a in the fixed key 301b-2 when rotating. At the same time, the outer wall of the movable cylinder 301b-1 is provided with a raised ring, and the ring rotates in the corresponding ring in the mounting hole 301a-5, which can prevent the movable cylinder 301b-1 from slipping out of the mounting hole 301a-5.

[0047] Example 3

[0048] Reference Figures 3 to 8, which is the third embodiment of the present invention. This embodiment is based on the above two embodiments. When in use, the mounting seat 401 is fixedly mounted on the existing rough rolling mill pressing table, so that the pressing roller 304 is downward, so as to roll the steel, and the double-axis motor works. One end of the double-axis motor 302 can drive the roller shaft 304a through the belt 303. The cross-section of the clamping section 304a-1 is square. The inner wall of the roller body 304b is attached to the outer wall of the clamping section 304a-1. After the roller shaft 304a and the clamping section 304a-1 are inserted into the roller body 304b, the rotation of the roller shaft 304a can drive the roller body 304b to rotate, and the roller body 304b can roll the steel when it rotates;

[0049] In the implementation manner of this embodiment, the other end of the dual-axis motor 302 can drive the fixed shaft 104a to rotate. When the fixed shaft 104a rotates, it can drive the driving gear 104b to rotate. The driving gear 104b meshes with the driven gear 104c. When the driving gear 104b rotates, it can drive the driven gear 104c to rotate. When the driven gear 104c rotates, it can drive the cylindrical body 101 to rotate. When the cylindrical body 101 rotates, it can drive the movable part 103 and the internal cylinder 201 to rotate, keeping the relative position between the cylinder 201 and the slide groove 101b and the movable part 103 unchanged. When the cylinder 201 extends, it can push the push block 202 to move. The length of the first movable rod 201a on the push block 202 is greater than the second movable rod 201b, and it can first contact the first protruding block 103e-1. When in use, the second spring 2 01a-1 has a greater elastic force than the first spring 103d. The elastic force of the first spring 103d is overcome and then compressed. The protruding block 103e-1 slides and drives the slider 103e to move. The slider 103e can slide on the fixed axis 103c and in the slide groove 101b. When the slider 103e moves, it can push the support rod 103b to move. The support rod 103b lifts the main rod 103a, so that the hinged part between the main rod 103a and the outer wall of the cylinder 101 rotates axially, and the main rod 103a stands up on the outer wall of the cylinder 101. When the protruding block 103e-1 moves to the side of the slide groove 101b close to and away from the push block 201, the position of the protruding block 103e-1 is fixed at this time. During the continued movement of the push block 202, the second spring 201a-1 inside the first movable rod 201a is compressed, and the first movable rod 201a slides in the movable groove 201c.

[0050] In the implementation manner of this embodiment, after the main rod 103a is erected, the teeth on the toggle block 103a-1 mesh with any teeth on the guide gear 406, and can toggle the guide gear 406 to rotate. When the guide gear 406 rotates, it can drive the internal threaded tube 405 to rotate. The guide gear 406 meshes with the teeth on the toggle block 103a-1. When the movable part 103 rotates with the cylinder 101, the toggle block 103a-1 also rotates accordingly. The teeth on the toggle block 103a-1 mesh with any teeth on the guide gear 406, and can toggle the guide gear 406 to rotate. When the guide gear 406 rotates, it can drive the internal threaded tube 405 to rotate. Under the action of the thread of the screw rod 403, the corrugated tube 405 moves along the screw rod 403 when the internal threaded tube 405 rotates. The internal threaded tube 405 can drive the fixed block 404 to move. The fixed block 404 can drive the workbench 301 to slide on the guide rail 402, and drive the pressure roller 304 to translate through the support seat 301a, which can change the contact position between the surface of the roller body 304b and the steel. The use of the moving roller body 304b can reduce the damage to the surface of the roller body 304b, can increase the life of the roller body 304b, can reduce the frequency of roller changing, which is beneficial to reduce the production time delayed by roller changing, and is beneficial to improve production efficiency.

[0051] In the implementation manner of this embodiment, when the first main rod 103a is erected, the teeth on the toggle block 103a-1 mesh with any teeth on the guide gear 406, the rotating shaft on the dual-axis motor 302 rotates one circle, the belt 303 can drive the roller shaft 304a to rotate one circle, the fixed shaft 104a drives the driven gear 104c to drive the cylinder 101 to rotate one circle, the teeth on the toggle block 103a-1 on the first main rod 103a in the movable part 103 mesh with any teeth on the guide gear 406, the guide gear 406 is rotated once, and the guide gear 406 drives the internal threaded tube 405 to rotate a certain angle. When the internal threaded tube 405 moves a certain distance along the screw rod 403, the internal threaded tube 405 drives the fixed block 404 to move a certain distance, driving the workbench 301 to slide on the guide rail 402, and drives the pressure roller 304 to translate a certain distance through the support seat 301a, which can change the position where the surface of the roller body 304b contacts the steel.

[0052] In the implementation manner of this embodiment, when the second main rod 103a is erected, the teeth on the toggle block 103a-1 can mesh with any teeth on the guide gear 406, and the rotating shaft on the dual-axis motor 302 rotates one circle. The teeth on the toggle block 103a-1 on the first main rod 103a and the second movable rod 201b in the movable member 103 respectively toggle the guide gear 406 to rotate once, and the guide gear 406 rotates twice in total. The guide gear 406 drives the internal threaded tube 405 to rotate, and the guide gear 406 rotates twice. 6 drives the internal threaded tube 405 to rotate twice as much as when only the first main rod 103a is erected, and finally drives the roller body 304b to translate twice as much as before. Similarly, when the cylinder 201 continues to move the push block 202, when the push block 202 contacts the raised block 103e-1, the remaining two raised blocks 103e-1 move, and finally the remaining two main rods 103a are erected. For each rotation of the rotating shaft on the dual-axis motor 302, the distance translated by only the roller body 304b is greater.

[0053] In the implementation mode of this embodiment, when the cylinder 201 contracts, it drives the push block 202 to move. When the push block 202 disengages from the movable part 103, the first spring 103d pushes the slider 103e to slide on the fixed shaft 103c, so that the slider 103e is reset. The slider 103e pulls the support rod 103b to move, and the support rod 103b pulls the main rod 103a, so that the hinged part between the main rod 103a and the outer wall of the cylinder 101 rotates axially. The main rod 103a is lowered and reset. The teeth on the toggle block 103a-1 disengage from any tooth on the guide gear 406. At this time, the toggle block 103a-1 cannot drive the guide gear 406 to rotate. Similarly, when the dual-axis motor 302 rotates, the internal threaded tube 405 cannot be linked to rotate. While the roller body 304b rotates, it no longer translates axially, which is more flexible to use.

[0054] In the implementation manner of this embodiment, the roller body 304b can be adjusted during the rolling production process. When the roller body rotates each circle, the corresponding axial translation changes the position where the surface of the roller body 304b contacts the steel. The adjustment control is more flexible and different translation amounts can be changed according to different rolling materials, which is beneficial to protecting the roller body 304b.

[0055] Example 4

[0056] Reference Figures 8-9, which is the fourth embodiment of the present invention. This embodiment is based on the above three embodiments. When the roller body 304b is replaced, the bolts on the screw holes on the clamping plate 301a-4 corresponding to the holes on the clamping plate 301a-4 on the workbench 301a are removed, so that the movable support block 301a-2 can be separated from the workbench 301a, and the movable support block 301a-2 slides in the clamping groove 301a-3, and the key groove 301b-4 on the movable cylinder 301b-1 is fixed on the fixed key 301b- 2, the movable support block 301a-2 can be removed, and since the roller shaft 304a slides through the fixed key 301b-2, the fixed key 301b-2 can be removed from the roller shaft 304a, and the roller body 304b can be slid from the roller shaft 304a near one end of the movable support block 301a-2 to remove it. When the roller body 304b is removed, the other end of the roller shaft 304a rotates and passes through the fixed support block 301a-1, without affecting the connection between the end of the roller shaft 304a and the belt 303.

[0057] After replacing the new roller body 304b, the new roller body 304b is sleeved on the roller shaft 304a, and the outer wall of the clamping section 304a-1 on the roller shaft 304a is in contact with the inner wall of the roller body 304b. The cross section of the clamping section 304a-1 is square, and the rotation of the roller shaft 304a can drive the roller body 304b to rotate. One end of the clamping section 304a-1 is raised to form a baffle 304a-2, which can limit the roller body 304b. 301b-2 is slidably sleeved on the roller shaft 304a relatively away from one end of the belt 303, and the limit plate 301b-3 on the fixed key 301b-2 is close to the roller body 304b. The limit plate 301b-3 cooperates with the baffle plate 304a-2 to limit the roller body 304b, preventing the roller body 304b from sliding in the axial direction of the roller shaft 304a. The fixed key 301b-2 is matched between the key slots 301b-4, and the movable support block 301a-2 is movable. The cylinder 301b-1 is inserted into the fixed key 301b-2, and the movable support block 301a-2 slides into the slot 301a-3. The bolt can pass through the hole on the clamping plate 301a-4 and screw into the screw hole on the workbench 301a corresponding to the hole on the clamping plate 301a-4. After tightening the bolt, the movable support block 301a-2 and the workbench 301a can be fixed together, and the movable cylinder 301b-1 can be inserted into the mounting hole 301a-5 on the movable support block 301a-2. The roller shaft 304a can rotate in the fixed key 301b-2 when rotating, and the cooperation of the fixed key 301b-2 and the keyway 301b-4 can drive the movable cylinder 301b-1 to rotate in the mounting hole 301a-5, which is beneficial to limit the roller shaft 304a and reduce the friction force when the roller shaft 304a rotates. At the same time, the disassembly and assembly of the roller body 304b is more convenient and quick, which is beneficial to reduce the time of replacing the roller body 304b, thereby improving production.
