Description

Technical Field

[0001] The utility model belongs to the technical field of bar production, and more specifically, relates to a steel retaining device for a bar production line and the bar production line. Background Art

[0002] When the bar production line is in continuous production, the steel billets are taken out of the heating furnace and enter the rolling mill through the automatically controlled conveyor roller for rolling. The interval between two adjacent steel billets is particularly short. During the production process, if a steel pile accident occurs after finishing or finished products, the steel billets on the conveyor roller that have already left the heating furnace cannot be stopped in time due to inertia, and will bite into the rolling mill, adding a piece of scrap, thereby affecting the yield index of the bar production line. In order to solve this problem, there is a steel retaining device for bar production lines in the prior art, which includes a steel retaining plate, a driving actuator and a control system; the action end of the driving actuator is connected to a lifting chain, and the lower end of the lifting chain is connected to the steel retaining plate; the driving actuator is fixed to the frame in front of the inlet guide of the rolling mill; the steel retaining plate is set to slide vertically, and the driving actuator receives the signal of the control system to drive the steel retaining plate to move up and down; when a fault occurs in the production line, it can act in time to make the steel retaining plate drop, preventing subsequent steel billets from entering the inlet guide, thereby protecting the safety of the steel billets and the rolling mill.

[0036] Specifically, to solve the problem that in the prior art, the steel blocking device uses a cylinder or a hydraulic cylinder to connect a guide chain 23 to hang a steel blocking plate 24, which affects the service life of the cylinder or the hydraulic cylinder and further affects the service life of the steel blocking device; the steel blocking device for a bar production line provided by the present utility model slidably arranges the steel blocking plate 24 between two columns 10, and the lifting mechanism 2 can drive the steel blocking plate 24 to lift, so that the steel blocking plate 24 can be lowered when a failure occurs in the bar production line, blocking subsequent billets from entering the inlet guide 1. The lifting mechanism 2 realizes the lifting of the steel blocking plate 24 by winding and releasing a flexible connecting member with a winding roller 22, and positions the steel blocking plate 24 at the lifted position by inserting a positioning block 202 of the positioning mechanism into a positioning groove 25 in the winding roller 22, and releases the steel blocking plate 24 by pulling out the positioning block 202 from the positioning groove 25, overcoming the problem that in the prior art, the steel blocking device uses a cylinder or a hydraulic cylinder to connect a guide chain 23 to hang a steel blocking plate 24, which affects the service life of the cylinder or the hydraulic cylinder and further affects the service life of the steel blocking device.

[0037] Optionally, vertical first sliding grooves 11 are arranged on one side of the two columns 10 close to each other, and two ends of the steel blocking plate 24 are respectively slidably embedded in the two first sliding grooves 11.

[0038] Specifically, the steel blocking plate 24 realizes sliding connection with the two columns 10 through the two first sliding grooves 11.

[0042] In this embodiment, sealing plates are arranged at the tops of the two columns 10, the sealing plates seal the upper ends of the first sliding grooves 11 in the columns 10 and can block the steel blocking plate 24, playing a limiting role for the steel blocking plate 24.

[0043] Optionally, the positioning mechanism includes:

[0044] The support 201 is connected to the side of the first plate body 20 away from the second plate body 21, and the support 201 is provided with a guiding through hole;

[0047] Specifically, the first motor 27 can drive the lead screw 29 to rotate. Since the lead screw 29 is threadedly connected to the internally threaded cylinder 28 and the internally threaded cylinder 28 is inserted into the guiding through hole, as the lead screw 29 rotates, the internally threaded cylinder 28 can drive the positioning block 202 to move along the axial direction of the lead screw 29, so that the positioning block 202 can be inserted into or pulled out from the positioning groove 25.

[0048] In this embodiment, the support 201 is U-shaped, its open end is connected to the first plate body 20, and the guiding through hole is opened at its closed end.

[0054] Optionally, an annular groove 205 is arranged in the middle of the winding roller 22, and the groove 205 can accommodate the flexible connecting member wound around the outer periphery of the winding roller 22.

[0055] Specifically, the groove 205 can accommodate the flexible connecting member and can play a role in limiting the flexible connecting member wound around the outer periphery of the winding roller 22, improving the stability of the operation of the device.

[0056] Optionally, the driving mechanism includes a second motor 207, and the second motor 207 is fixedly connected to the second plate body 21 through a fixing plate 206.

[0059] Specifically, the positioning groove 25 can be various shapes other than cylindrical, such as triangular prism shape, square shape, semi-circular shape or polygonal shape, as long as it can restrict the rotation of the coiling roller 22 when the positioning block 202 is inserted into the positioning groove 25.

[0060] The present utility model further provides a bar production line, which includes the above-described steel bar blocking device for the bar production line, and the steel bar blocking device for the bar production line is arranged on the front side of the inlet guide 1.

[0061] Specifically, the steel bar blocking device for the bar production line can be arranged at the upstream position of the inlet guide 1, and it can block the subsequent billets from entering the inlet guide 1 by using the dropped steel bar blocking plate 24 after releasing the coiling roller 22, so as to protect the safety of the billets and the safety of the rolling mill.

[0062] In this embodiment, the two columns 10 are connected to the front side of the inlet guide 1, and the two share the same base.

[0063] In summary, when the steel bar blocking device provided by the present utility model for a bar production line is in use, taking the normal operation of the bar production line and the blocking steel plate 24 being in the raised position as an example: when a process failure occurs in the bar production line, the first motor 27 is started, and the lead screw 29 is driven by the first motor 27 to rotate counterclockwise, so that the internally threaded cylinder body 28 can drive the positioning block 202 to move out of the positioning groove 25, causing the winding roller 22 to lose its positioning, thereby releasing the guide chain 23, enabling the blocking steel plate 24 to move downward under the action of gravity and preventing the next billet from entering the inlet guide 1, preventing the billet from being rolled waste due to inertia and being unable to stop biting into the rolling mill in time. After the failure of the bar production line is processed, the second motor 207 is started, and the winding roller 22 is driven by the second motor 207 to wind the guide chain 23, so that the blocking steel plate 24 is lifted to the raised position. After reaching the position, the sealing plate at the top of the column 10 can limit the blocking steel plate 24. At the same time, the lead screw 29 is driven by the first motor 27 to rotate clockwise, so that the internally threaded cylinder body 28 drives the positioning block 202 to insert into the positioning groove 25, thereby positioning the winding roller 22 again and keeping the blocking steel plate 24 in the raised position. The running timing and speed of the first motor 27 and the second motor 207 can be set so that when the blocking steel plate 24 reaches the raised position, the first motor 27 immediately drives the positioning block 202 to insert into the positioning groove 25, and then the operation of the second motor 207 is stopped. The short-term stop of the blocking steel plate 24 in place without movement will not cause damage to the second motor 207.

[0064] The embodiments of the present utility model have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
