Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing.
[0026] Depend on figure 1 It can be seen that the strip coiling device is mainly composed of a reel 1, a guide plate 3, a pressure roller 5, a pressure roller base 8 and a pneumatic valve 9 that controls the lifting of the guide plate 3. At the jaw 2, the strip steel 6 running horizontally is turned back at a certain angle after being processed by the pressure roller 5, and the lead enters the jaw 2 along the guide plate 3 for normal coiling.
[0027] The concrete steps of the method that the present invention introduces the warped strip steel into the reel jaw are:
[0028] 1. Preliminary preparation:
[0029] a. Process the semicircular draw-in groove 4 with a steel plate, respectively drill pin holes at the corresponding positions of the two free ends of the draw-in groove 4, and make a safety pin 12 matching the diameter of the pin hole.
[0030] b. A support rod 7 i...

The invention provides a method for introducing a warped-head steel strip into a reeling nipper jaw. A clamping slot is welded on the lower surface of a guiding plate of a reeling machine and a supporting rod is hinged with a press roller base. The method comprises the following steps: moving the guiding plate of the reeling machine and the reeling nipper jaw to preset positions; stopping inching when a strip head is 40-70mm away from the reeling nipper jaw; if the steel strip has a warped-head, closing a pneumatic valve of the guiding plate; placing the upper end of the supporting rod into the clamping slot and supporting the guiding plate; inserting a safety pin for fixing; forward inching the steel strip; hooking the steel strip from the two sides of the guiding plate by an adjuster by utilizing an adjusting hook and smoothly introducing the strip head into the reeling nipper jaw; and moving the supporting rod from the clamping slot and opening the pneumatic valve. According to the method provided by the invention, the potential safety hazard during the strip guiding process is eliminated; the probability of generating steel clamping and steel stacking phenomena during a reeling process at an outlet is obviously reduced; the accident handling time is shortened; the reduction of speed of machine set and the parking accident are avoided; the operation efficiency of equipment and machine set is increased; and the yield of silicon steel is increased by above 2%.
Description
technical field [0001] The invention belongs to the field of steel rolling machinery and equipment, and in particular relates to a method for safely and smoothly introducing the head (that is, the head) of a warped steel strip into the nip of a reel of a coiler. Background technique [0002] At present, domestic high-performance silicon steel normalization pickling units generally adopt the coiling mode of the reel jaws of the coiler for coiling. Before coiling, the strip steel is firstly heat-treated by an edge heating device to improve the toughness of the strip head, and then the strip head is cut at the exit slitter. Through tracking and summarizing the production process, it was found that due to the restriction of incoming materials in the normalization pickling unit, the edge of the strip was upturned. After the automatic leader of such a belt is brought to the coiler, it is easy to bump into the jaw edge of the reel, causing the coiling to be unable to continue. If...
