[0001] The utility model relates to the technical field of hot-rolled strip coiling, in particular to a hydraulic jaw coiling device for a hot-rolled strip slitting unit. Background Technique

[0002] Hot-rolled strip generally refers to coiled strip with a thickness of 1 - 20 mm and a width generally of 600 - 2000 mm. The strip slitting machine is a shearing mechanical device widely used in fields such as iron and steel, metal, plastic, and rubber. It can divide large coils of steel plates or strips into materials with specified lengths and widths, thereby meeting the needs of customers in different fields. Strip slitting has wide applications in fields such as iron and steel enterprises, construction enterprises, automobile manufacturing enterprises, and power equipment manufacturing enterprises.

[0003] After the hot-rolled strip is sheared, a coiling process is required. During the coiling of the hot-rolled strip, due to reasons such as tension setting, the coil shape of the strip is poor during coiling, which is not conducive to the production and transportation of the hot-rolled strip. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hydraulic jaw coiling device for a hot-rolled strip slitting unit to solve the problem of poor flatness of the coil shape proposed in the above background technique.

The tensioning mechanism drives the turntable by screwing the threaded rod to make the expansion plate expand outwards.

[0006] Preferably, the tensioning mechanism includes: one end of the output shaft of the motor is fixedly connected with a connecting shaft, one surface of the connecting shaft is fixedly connected with a fixing plate, one side surface of the fixing plate is fixedly connected with a connecting rod, one surface of the connecting rod is fixedly connected with a positioning plate, a slide rail I is fixedly connected inside the positioning plate, a slider I is slidably connected to the upper surface of the slide rail I, a positioning rod is fixedly connected to the upper surface of the slider I, an expansion plate is fixedly installed on one surface of the slider I, a positioning bolt III is threadedly connected to the surface of the expansion plate, a threaded rod is threadedly connected to the center of the positioning plate, and a turntable is fixedly connected to one surface of the threaded rod.

[0007] Adopting the above technical solution provides a structural basis for the tensioning mechanism.

The limiting mechanism includes: a second slide rail fixedly connected to one side surface of the support plate. A second slider is slidably connected to one side surface of the second slide rail.

[0010] Preferably, a through hole is provided on one side surface of the support frame, and one end of the output shaft of the motor penetrates through the hole of the support frame.

[0011] Adopting the above technical solution facilitates the rotation of the expansion plate.

[0012] Preferably, a groove is provided inside the positioning plate. The first slide rail and the first slider are both arranged inside the groove of the positioning plate. An opening is provided on the surface of the positioning plate, and the positioning rod is arranged inside the opening on the surface of the positioning plate.

[0013] Adopting the above technical solution facilitates the outward expansion of the expansion plate.

[0014] Preferably, an arc-shaped opening is provided on the surface of the turntable. One end of the positioning rod penetrates through the arc-shaped opening of the turntable. A through threaded hole is provided at the center of the positioning plate. One end of the threaded rod penetrates through and is provided with an iron rod.

[0018] Compared with the prior art, the beneficial effects of the present utility model are: the hydraulic jaw coiling device of the hot-rolled strip longitudinal shearing unit:

[0019] 1. The tensioning mechanism improves the neatness of winding. When winding is required, the rotating shaft is adjusted to an appropriate position, and one end of the strip is placed on the upper surface of the expansion plate. Subsequently, a small section of one end of the strip is folded to the lower end of the expansion plate. Then the motor is started, and the expansion plates on the positioning plate rotate simultaneously to wind the strip. During the winding process, if the neatness of the strip is poor, rotate the threaded rod to continuously expand the expansion plate, thereby flattening the wound strip. This mechanism can reduce the gap between the strips during the winding process of the strip through the continuous expansion of the expansion plate, thereby improving the tightness of the wound material.

[0020] 2. The limiting mechanism prevents the strip from shifting during the winding process. Before winding, one end of the strip is passed through the lower end of the rotating shaft. Subsequently, the position of the limiting plate is slid according to the width of the strip, and the positioning bolt one at the upper end of the limiting plate is tightened, thereby determining the position of the limiting plate on the surface of the rotating shaft. When adjusting the tightness of the strip transmission, adjust the position of the slider two on the slide rail two. The lower the position of the rotating shaft, the greater the tightness of the strip. This mechanism prevents the strip from shifting left and right through the limiting plate, and adjusting the tightness is beneficial for the strip to be evenly wound on the surface of the expansion plate.
