Description

Technical Field

[0001] The utility model belongs to the technical field of strip steel production, and particularly relates to a coiler pressing structure of a cold rolling strip steel mill. Background Art

[0002] Cold rolling of strip steel is a production process in steel processing. By the cold extrusion method, the cold-rolled strip steel and thin plates generally have a thickness of 0.1 - 3 mm and a width of 100 - 2000 mm; they are all made from hot-rolled strip steel or steel plates and are rolled into finished products by a cold rolling mill at room temperature.

[0003] In the existing cold rolling production process of strip steel, the cold-rolled formed strip steel is wound by a coiler. During the winding process, due to the certain hardness of the strip steel itself, gaps are likely to appear between the strip steels during winding, resulting in an increase in the volume of the wound steel coil and a reduction in the winding quality. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a coiler pressing structure of a cold rolling strip steel mill.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a coiler pressing structure of a cold rolling strip steel mill, including a machine body. A support mechanism is installed on one side of the machine body, and a coiling roller is fixed outside the support mechanism. Two groups of limiting mechanisms are symmetrically arranged at the bottom end of the coiling roller. The limiting mechanism is provided with two groups of limiting rollers located below the coiling roller. A fork arm is rotatably connected to the outside of the limiting roller. The two groups of fork arms cross each other, and a connecting shaft is rotatably connected at the connection of the two groups of fork arms. A connecting seat is installed at the bottom end of the fork arm, and a base is rotatably connected to the outside of the bottom end of the connecting seat.

[0006] Specifically, a guiding mechanism is arranged outside the base. The guiding mechanism is provided with a guide rod. The guide rod penetrates through the base, and the base is slidably connected to the guide rod. Both ends of the guide rod are fixedly connected to a support seat.

[0007] Specifically, the guiding mechanism is further provided with a return spring. The return spring is located between the base and the support seat, and the return spring is nested outside the guide rod.

[0008] Specifically, an adjusting mechanism is arranged below the guiding mechanism. The adjusting mechanism is provided with an electric telescopic rod and a bottom plate fixedly connected to the electric telescopic rod.

[0009] Specifically, there are four electric telescopic rods, and they are symmetrically installed at the bottom end of the base.

[0010] Specifically, a driving motor is installed on the machine body on the side opposite to the support mechanism, and the output end of the driving motor is fixedly connected to the support mechanism.

[0011] Specifically, the support mechanism includes a support shaft located in the middle of the winding roll. A convex rib is provided at the top of the support shaft, and a fitting groove is formed on one side of the winding roll facing the convex rib. A limiting plate is fixed on one side of the winding roll, and a fixing plate is connected to the other side of the winding roll by threads.

[0012] The utility model has the following beneficial effects: By setting the limiting mechanism and the guiding structure, during the winding process of the strip steel, the limiting roller in the limiting mechanism contacts the strip steel to limit it. And during the process of the coiling diameter of the strip steel continuously increasing, the strip steel presses the limiting roller, and the limiting roller drives the fork arm to rotate along the connecting shaft, thereby enabling the connecting seat to rotate along the base. At the same time, the base moves along the guide rod and presses the return spring. The return spring applies a reaction force to enable the limiting roller to be in close contact with the strip steel, so as to press the strip steel tightly during the winding process, avoid gaps between the strip steels, prevent the volume of the coiled steel after winding from increasing, and improve the winding quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Now, the utility model will be further described in detail with reference to the accompanying drawings.

[0018] Such as Figures 1-3As shown in the figure, a coiling press structure of a cold rolling strip mill includes a machine body 1. On one side of the machine body 1, a support mechanism 2 is installed. The support mechanism 2 can support the coiling roll 3. The coiling roll 3 is fixed outside the support mechanism 2. The coiling roll 3 can coil the strip steel. At the bottom end of the coiling roll 3, two groups of limiting mechanisms 4 are symmetrically arranged. The limiting mechanism 4 includes two groups of limiting rollers 401 located below the coiling roll 3. The limiting rollers 401 can be in close contact with the strip steel to limit it, thereby pressing the strip steel. A fork arm 402 is rotatably connected to the outside of the limiting roller 401. The fork arm 402 can rotate along the connecting shaft 403 under force. The two fork arms 402 cross each other, and a connecting shaft 403 is rotatably connected at the connection of the two fork arms 402. The connecting shaft 403 can support the fork arm 402. A connecting seat 404 is installed at the bottom end of the fork arm 402. The connecting seat 404 can be rotatably connected to the base 405 to ensure the horizontal movement of the base 405. The bottom end of the connecting seat 404 is rotatably connected to the base 405, and the base 405 can move along the guide rod 501 to compress the return spring 502.

[0019] As Figures 1-2 shown, a guiding mechanism 5 is arranged outside the base 405. The guiding mechanism 5 includes a guide rod 501, a return spring 502, and a support seat 503, which can guide the movement of the base 405 through the guiding mechanism 5. The guide rod 501 penetrates the base 405, and the base 405 is slidably connected to the guide rod 501. Both ends of the guide rod 501 are fixedly connected to the support seat 503, which facilitates the movement of the base 405 along the guide rod 501 in the support seat 503 and guides it through the guide rod 501. The return spring 502 is located between the base 405 and the support seat 503, and the return spring 502 is nested outside the guide rod 501. The base 405 will compress the return spring 502 during the movement along the guide rod 501, and the reaction force generated by the return spring 502 is applied to the base 405, so that the limiting roller 401 can be in close contact with the strip steel.

[0020] As Figures 1-2 shown, an adjusting mechanism 6 is arranged below the guiding mechanism 5. The adjusting mechanism 6 includes an electric telescopic rod 601 and a bottom plate 602, which facilitates the adjustment of the horizontal height of the limiting mechanism 4 and the guiding mechanism 5 through the adjusting mechanism 6. There are four electric telescopic rods 601 in total, and they are symmetrically installed at the bottom end of the base 405. The bottom end of the electric telescopic rod 601 is fixedly connected to the bottom plate 602, which can support the electric telescopic rod 601 through the bottom plate 602 and facilitate the electric telescopic rod 601 to drive the support seat 503 to lift and lower.

[0021] As Figure 1 shown, a driving motor 7 is installed on the machine body 1 on the side opposite to the support mechanism 2, and the output end of the driving motor 7 is fixedly connected to the support mechanism 2, which facilitates driving the support mechanism 2 to rotate through the driving motor 7, thereby coiling the strip steel.

[0022] As Figure 1 and Figure 3 shown, the support mechanism 2 includes a support shaft 201 located in the middle of the winding roller 3. The support shaft 201 can carry the winding roller 3. A convex rib 202 is provided at the top of the support shaft 201. The winding roller 3 can rotate synchronously through the convex rib 202 when installed on the support shaft 201. And a fitting groove is provided on one side of the winding roller 3 facing the convex rib 202. A limiting plate 203 is fixed on one side of the winding roller 3. The limiting plate 203 can limit one end of the winding roller 3. On the other side of the winding roller 3, a fixing plate 204 is connected by a thread. The fixing plate 204 can fix the winding roller 3 on the support shaft 201.

[0023] The working principle of this device: When in use, the staff installs the winding roller 3 outside the support shaft 201, and makes one end of the winding roller 3 abut against the limiting plate 203. The convex rib 202 on the support shaft 201 is engaged into the groove on the winding roller 3. After the installation is completed, the fixing plate 204 is installed on the support shaft 201 to fix the winding roller 3. After the fixing is completed, the driving motor 7 on one side of the machine body 1 drives the support mechanism 2 to rotate, so that the winding roller 3 rotates to wind the strip steel;

[0024] During the winding process, the limiting roller 401 in the limiting mechanism 4 can limit the strip steel. And during the process that the coiling diameter of the strip steel continuously becomes larger, the strip steel presses the limiting roller 401. The limiting roller 401 drives the fork arm 402 to rotate along the connecting shaft 403, and further makes the connecting seat 404 rotate along the base 405. At the same time, the base 405 will move along the guide rod 501 and press the return spring 502. By applying a reaction force through the return spring 502, the limiting roller 401 can be in close contact with the strip steel, so as to press the strip steel tightly during the winding process, avoid gaps between the strip steels, prevent the volume of the wound steel coil from increasing, and improve the winding quality;

[0025] And after a single winding is completed, the electric telescopic rod 601 at the top of the bottom plate 602 adjusts the horizontal height of the guiding mechanism 5 and the limiting mechanism 4 to below the winding roller 3, which is convenient for the winding roller 3 to be separated from the support mechanism 2, so as to meet the subsequent winding requirements.
