Embodiment
[0044] (1). When the strip coiling of the coiler is about to be completed, 2 # The auxiliary winding roller is opened to the limit position, and the idler roller of the unloading trolley rises from the initial position to the standby position at high speed;
[0045] (2).1 # 、3 # The winding-assisting roller presses the tail end of the strip steel, and the tail end of the strip steel is driven by the reel to stop at the designated position;
[0046] (3). The idler roller of the unloading trolley rises at a low speed from the standby position, supports the steel coil and stops after reaching the set pressure;
[0047] (4).1 # 、3 # The winding-assisting roller is opened to the limit position;
[0048] (5). The reel shrinks to the specified diameter, and the reel jaws are opened;
[0049] (6). The roller of the unloading trolley is locked by the locking device installed on the unloading trolley;
[0050] (7).1 # and 3 # The roll-assisting roller compresses the steel coil;...

The invention discloses a coil discharging method of a jaw type coiling machine. During the automatic coil discharging process of a coil discharging trolley, after diameter reduction of a coiling block and the opening of a jaw, a motor is used for driving the coiling block to rotate, for a certain angle, to a direction opposite to the rotation direction of the coiling block during normal coiling, and then rest coil discharging actions are actuated sequentially. According to the method provided by the invention, by rotating the coiling block for a certain angle towards the direction opposite to the rotation direction of the coiling block during normal coiling, friction force between the head part of a strip steel and a tongue plate of the jaw is reduced, so that the head part of the strip steel can be horizontally extracted out from the jaw quickly and smoothly. Therefore, the coil discharging speed and the work efficiency of an entire rolling mill are improved, moreover, the problems of tower-shaped inner coiling of a steel coil, inner surface scraping of the steel coil and the like can be solved, and the product quality is improved.
Description
technical field [0001] The invention relates to the technical field of cold rolling, in particular to a coil unloading method for a jaw type coiler. Background technique [0002] In the production of strip steel, the continuous and smooth rolling rhythm is related to the production efficiency of the strip steel, and the steel coil without tower shape is related to the product quality of the strip steel. The automatic coil unloading program of the steel coil is an important part of the strip steel production process. If the coil unloading is not smooth, it will not only affect the continuity of production, but also may cause the inner coil of the steel coil to be tower-shaped, which will affect the product quality. [0003] The equipment involved in the strip coiling process mainly includes coilers, unloading trolleys, etc. Jaw crimping machine is a kind of coiling machine widely used, which is composed of motor, reducer, reel, winding auxiliary roller and so on. The reel i...
