Description

Technical Field

[0001] This utility model relates to the field of external support for winding machines, and specifically to an external support structure for winding machines. Background Technology

[0002] Traditional cold-rolled steel coils have two structural forms: solid roll winding and expansion / contraction roll winding. For expansion / contraction roll winding, because high-tension rolling is used on the rolling mill, external support is required. Traditional large rolling mills use a swing gate structure, which is complex, bulky, and unsightly. At the same time, the lateral swing method affects the space on the operating side, and swing space must be left. This results in a large hole in the grid plate on the operating side when the swing gate is closed, which the operator needs to knock on frequently during the rolling process. The presence of this hole poses a safety hazard. Utility Model Content

[0003] Based on the above description, this utility model provides an external support structure for a winding machine to solve the problem that the lateral swaying of the external support poses a safety hazard to the operator during operation.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an external support structure for a winding machine, including an external support arm for supporting the shaft core of the winding machine;

[0005] One end of the outer support arm is hinged to the first fixed base, and a first movable arm is movably connected to one side of the outer support arm via a hinge. A second movable arm is movably connected to one end of the first movable arm via a hinge. The end of the second movable arm away from the first movable arm is hinged to the second fixed base. A movable groove is provided on the second movable arm, and a roller is movably connected to the inner wall of the movable groove. A hydraulic rod is movably connected to one side of the roller via a rotating shaft. One end of the hydraulic rod is fixedly installed on the wall.

[0006] Furthermore, the outer support arm is provided with a mounting groove, the inner wall of the mounting groove is provided with a support part, the top of the support part is provided with an arc groove, and a ball bearing is installed inside the arc groove.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the support portion includes a first support block and a second support block, the first support block and the second support block are fitted together, and both the first support block and the second support block are located in the mounting groove.

[0009] Furthermore, a groove is formed in the inner wall of the mounting groove, and a protrusion is installed at the bottom of both the first support block and the second support block, with the end of the protrusion away from the first support block and the second support block inserted into the inner cavity of the groove.

[0010] Furthermore, the sidewall of the protrusion is movably connected to a threaded rod via a bearing, and the end of the threaded rod away from the protrusion is threaded through the sidewall of the groove.

[0011] Furthermore, the tops of both the first and second support blocks are equipped with ball bearings, which are evenly embedded in the inner cavity of the arc groove.

[0012] Furthermore, the ball is located at the gap where the first support block and the second support block fit together, and the ball rotates freely in the inner cavity of the arc groove.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0027] Please see Figure 1 and Figure 2An external support structure for a winding machine includes an external support arm 2 for supporting the winding machine shaft core 1;

[0028] One end of the outer support arm 2 is hinged to the first fixed base, and a first movable arm 3 is movably connected to one side of the outer support arm 2 via a hinge. A second movable arm 4 is movably connected to one end of the first movable arm 3 via a hinge. The end of the second movable arm 4 away from the first movable arm 3 is hinged to the second fixed base, and a movable groove is provided on the second movable arm 4. A roller is movably connected to the inner wall of the movable groove, and a hydraulic rod 5 is movably connected to one side of the roller via a rotating shaft. One end of the hydraulic rod 5 is fixedly installed on the wall. When the hydraulic rod 5 is activated, the hydraulic rod 5 retracts. When retracting, the roller slides in the groove of the second movable arm 4, causing the second movable arm 4 to rotate. The rotation of the second movable arm 4 then causes the first movable arm 3 to rotate, which in turn causes the outer support arm 2 to rotate, thereby completing the retraction of the outer support arm 2. Conversely, when the hydraulic rod 5 extends, the outer support arm 2 will unfold.

[0029] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, the outer support arm 2 is provided with an installation groove 21, the inner wall of the installation groove 21 is provided with a support part 22, the top of the support part 22 is provided with an arc groove, and the inside of the arc groove is provided with a ball bearing 25.

[0030] In order to reduce the friction between the support part 22 and the winding machine shaft 1, ball bearings 25 are installed on the first support block 221 and the second support block 222. The ball bearings 25 are used to contact the winding machine shaft 1, which can reduce wear between the two while maintaining the support function for the winding machine shaft 1.

[0031] Please see Figure 3 , Figure 4 and Figure 5 The support portion 22 in this embodiment includes a first support block 221 and a second support block 222. The first support block 221 and the second support block 222 are fitted together, and both the first support block 221 and the second support block 222 are located in the mounting groove 21.

[0032] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, a groove 23 is provided in the inner wall of the mounting groove 21. A protrusion 26 is installed at the bottom of the first support block 221 and the second support block 222, and the end of the protrusion 26 away from the first support block 221 and the second support block 222 is inserted into the inner cavity of the groove 23.

[0033] Please see Figure 3 , Figure 4 and Figure 5In this embodiment, the sidewall of the protrusion 26 is movably connected to a threaded rod 24 via a bearing, and the end of the threaded rod 24 away from the protrusion 26 is threaded through the sidewall of the groove 23.

[0034] By rotating the threaded rod 24, the protrusion 26 can slide in the inner cavity of the groove 23. The sliding of the protrusion 26, in turn, causes the first support block 221 and the second support block 222 to slide, thereby realizing the separation and closing of the first support block 221 and the second support block 222.

[0035] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, the balls 25 on the top of the first support block 221 and the second support block 222 are distributed in an arc shape, and the balls 25 are evenly embedded in the inner cavity of the arc groove. The arrangement of multiple balls 25 in the inner cavity of the arc groove is used to reduce the friction between the arc groove and the winding machine shaft 1, thereby protecting the winding machine shaft 1.

[0036] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, the ball bearing 25 is located at the gap where the first support block 221 and the second support block 222 fit together, and the ball bearing 25 rotates freely in the inner cavity of the arc groove.

[0037] When the threaded rod 24 rotates, the first support block 221 and the second support block 222 will separate, which makes it convenient to spray lubricating oil at the gap to further reduce the friction of the ball 25, and also allows the ball 25 to be disassembled for maintenance.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
