Description

Technical Field

[0001] The utility model relates to the technical field of steel coil auxiliary rolling, in particular to a novel double-mode auxiliary rolling machine. Background Art

[0002] In the process of steel coil production, the steel plate needs to be packaged after being coiled. When the steel plate is coiled, it is necessary to assist in coiling at the beginning of coiling because the steel plate is not easy to bend. Generally, the steel coiling method is to manually assist in coiling with a steel plate clamp or to use a simple coiling machine. However, both methods have certain disadvantages. Manual coiling will result in low work efficiency and high safety. Existing coiling machines are often semi-automatic and can only assist in one-way coiling. Therefore, a coiling machine with high automation, high safety and high security is needed. Utility Model Content

The other end of the cylinder mounting plate 18 is fixedly connected to the connecting plate 4.

[0019] An upper jib 5 is also fixedly mounted on the boom 10, a connecting rod B14 is fixedly mounted inside the main boom 13, a tensioning arm 24 is fixedly mounted on the main boom 13, a rotating shaft B3 is fixedly mounted inside the tensioning arm 24, an oil cylinder A1 is fixedly mounted between the rotating shaft B3 and the connecting rod B14, a rotating shaft C9 is also fixedly mounted inside the lower jib 7, a number of connecting rods A8 are fixedly mounted between the rotating shaft C9 and the boom 10, and a number of oil cylinders C12 are symmetrically mounted between the main boom 13 and the upper jib 5.

[0020] In this embodiment, the side of the main arm 13 is in a herringbone structure, and the connection blocks A11 and B19 are connected to the main arm 13 by bolts. Through the action of the connection blocks A11 and B19, the main arm 13 is connected to the boom 10. The lower jib 7 is connected to the boom 10 through the connecting rod D16 installed on the boom 10, and the lower jib 7 is rotated through the connecting rod D16. The connecting rod C15 has the same function as the connecting rod D16, which is mainly used to connect the upper jib 5 and rotate the upper jib 5. The main arm 13 is sleeved on the rotating shaft A2. When the rotating shaft A2 rotates, the main arm 13 is driven to rotate. It is installed on the winding plate 4 through the connecting plate 4. The cylinder B6 on the machine drives the rotating shaft A2 to drive the main arm 13 to rotate to realize the winding operation. The cylinder B6 transmits power to the rotating shaft A2 through the cylinder drive connection 17. The connection between the main arm 13 and the connecting rod B14 is welded, and the connection between the upper auxiliary arm 5 and the rotating shaft B3 is also welded. The main function of the cylinder A1 installed between the connecting rod B14 and the rotating shaft B3 is to realize the tightening and loosening of the upper auxiliary arm 5 by oil inlet and oil return. Two connecting rods A8 are provided, and the connecting rod A8 is also connected to the cylinder. The main function of the connecting rod A8 is to transmit the force of the cylinder to the rotating shaft C9, thereby realizing the tightening and loosening of the lower auxiliary arm 7.

[0021] Specifically, a plurality of intermediate fixing plates 20 are fixedly mounted in the middle portion of the connecting plate 4 , and a plurality of reinforcing ribs 21 are fixedly mounted on the connecting plate 4 .

[0022] In this embodiment, three intermediate fixing plates 20 are welded on the connecting plate 4 , and their main function is to ensure the stability of the connecting plate 4 .

[0024] In this embodiment, the reinforcing column 23 and the back plate 22 are fixed to ensure the safety of the arm 10 and the main arm 13 .

[0025] The working principle and use process of this utility model:

[0026] Upper coiling status:

[0027] The return oil of the oil cylinder drives the connecting rod A8 to retract, so that the lower auxiliary arm 7 becomes the unfolded state, and the upper auxiliary arm 5 also becomes the unfolded state due to the return oil of the oil cylinder A1. At this time, the oil cylinder B6 drives the rotating shaft A2 to rotate, thereby driving the main arm 13 to move to the winding shaft of the coiler, and then the oil inlet of the oil cylinder A1 closes the upper auxiliary arm 5, thereby pressing the steel plate onto the winding shaft from the upper side;

[0028] Lower coiling status:

[0029] The initial state is the same as the upper winding state. When the main arm 13 reaches the specified position driven by the rotating shaft A2, the oil cylinders behind the two connecting rods A8 start to take in oil, thereby pushing the lower auxiliary arm 7 to close, thus realizing the lower winding.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
