Description

Technical Field

[0001] The utility model relates to the field of strip steel processing, in particular to a rolling device for strip steel after annealing. Background Art

[0002] Rolling of steel strip after annealing is one of the common process steps in steel production. When rolling steel strip after annealing, a special rolling device is generally used to operate it. The annealed steel strip is fed into the rolling device, and then the rolling device is started for rolling. However, if the steel strip is rolled directly, it is difficult to press it directly to the expected state at one time due to the hard texture of the steel strip itself, and in the process, the steel strip may break due to excessive force applied.

[0003] Therefore, in order to solve the above problems, a rolling device after strip annealing is developed to preheat and soften the strip and reduce the difficulty of pressing. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices that directly roll the steel strip, since the texture of the steel strip itself is relatively hard, it is difficult to directly press it to the expected state at one time, and in this process the steel strip may be broken due to excessive force applied, the utility model provides a rolling device after annealing of the steel strip, which can preheat and soften the steel strip and reduce the difficulty of pressing.

[0005] The technical solution of the utility model is: a rolling device after annealing of strip steel, comprising a base, a mounting frame is installed on the top of the base by bolts, a pressure roller is rotatably connected to the lower part of the mounting frame, the pressure roller is slidably and rotatably connected to the upper part of the mounting frame, the left side of the pressure roller is connected to a connection port for connecting to a motor, and a preheating mechanism for preheating and softening the strip steel is arranged on a placement plate.

[0006] In one embodiment, the preheating mechanism includes a mounting plate, the front sides of the left and right parts of the placement plate are connected to the mounting plate, air inlets are opened on the mounting plate, and a heating component is connected between the upper and lower parts of the mounting plate.

[0007] In one of the embodiments, a guiding mechanism is also included, and the guiding mechanism includes a fixed sleeve, and the fixed sleeves are connected to the rear sides of the left and right parts of the installation frame, and the fixed sleeves are slidably connected to sliding frames, and guide rollers for guiding and supporting the discharge of the rolled strip are rotatably connected between the sliding frames.

[0008] In one of the embodiments, the upper sides of the left and right parts of the installation frame are connected with adjustment components, and the adjustment components are threadedly connected to the pressure roller on the upper side.

[0009] In one of the embodiments, a placement plate is installed between the left and right side walls of the front inner portion of the installation frame by bolts.

[0010] In one of the embodiments, each of the air inlets is connected to a connecting pipe.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] 1. When the utility model rolls the strip steel, the heating component will preheat the strip steel, so that the strip steel can be softened and the rolling efficiency is improved. During the heating process, gas can be injected through the connecting pipe so that the airflow circulates between the heating components to improve the heating efficiency of the strip steel.

[0013] 2. When the strip steel is discharged after rolling, the guide roller can be pulled backwards to make the sliding frame slide backwards along the guide sleeve, thereby supporting and guiding the strip steel after discharge, so that the strip steel can stably enter the next process and avoid the strip steel falling.

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited. Example 1

[0020] A rolling device for strip steel after annealing, such as Figure 1 and Figure 2As shown, it includes a base 1, a mounting frame 2 is installed on the top of the base 1 by bolts, a pressure roller 3 is rotatably connected to the lower part of the mounting frame 2, a pressure roller 3 is slidably and rotatably connected to the upper part of the mounting frame 2, a connection port 5 for connecting to a motor is connected to the left side of the pressure roller 3, an adjustment component 4 is connected to the upper side of the left and right parts of the mounting frame 2, the adjustment component 4 is threadedly connected to the pressure roller 3 on the upper side, a placement plate 6 is installed between the left and right side walls of the inner front of the mounting frame 2 by bolts, and a preheating mechanism 7 for preheating and softening the strip is arranged on the placement plate 6.

[0021] like Figure 1 and Figure 3 As shown, the preheating mechanism 7 includes a mounting plate 71, and the front sides of the left and right parts of the placement plate 6 are connected to the mounting plate 71, and the mounting plate 71 is provided with an air inlet 72, and the air inlet 72 is connected to a connecting pipe, and a heating component 73 is connected between the upper and lower parts of the mounting plate 71.

[0022] It should be noted that after the strip is annealed, it needs to be rolled. At this time, the present device can be used for auxiliary processing. First, the movement of the adjusting component 4 is controlled so that the upper pressure roller 3 can move upward and unfold, and then the strip is passed from the front side of the mounting frame 2 through the heating component 73 and the two pressure rollers 3 in sequence. After the processing is completed, the adjusting component 4 is controlled to drive the upper pressure roller 3 to reset so that the pressure roller 3 can extrude the strip. After the preparation work is completed, the motor output shaft is connected to the connecting port 5, and then the motor is started. After the motor is started, it will drive the pressure roller 3 to rotate, thereby completing the rolling processing of the strip. The rolled strip will move backward for discharge. It should be particularly noted that when the strip is rolled, the heating component 73 will preheat the strip, so that the strip can be softened and the rolling efficiency is improved. During the heating process, gas can be injected through the connecting pipe so that the airflow circulates between the heating components 73 to improve the heating efficiency of the strip. Example 2

[0023] On the basis of Example 1, Figure 1 and Figure 4 As shown, it also includes a guiding mechanism 8, which includes a fixed sleeve 81. The fixed sleeves 81 are connected to the rear sides of the left and right parts of the mounting frame 2. The fixed sleeves 81 are slidably connected to the sliding frames 82. The sliding frames 82 are rotatably connected to guide rollers 83 for guiding and supporting the unloading of the rolled strip.

[0024] It should be noted that when the strip is discharged after rolling, the guide roller 83 can be pulled backward so that the sliding frame 82 slides backward along the guide sleeve, thereby supporting and guiding the strip after discharge, so that the strip can stably enter the next process and avoid the strip falling.

[0025] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
