Description

Technical Field

[0001] This utility model relates to the field of bundling and forming technology, and in particular to a bundling and forming device and a finishing and forming device for a double-high bar production line. Background Technology

[0002] In steel manufacturing, the finishing and forming unit of a double-high-strength bar production line is used for cold shearing, automated counting, roller collection, and bundling of the rebar rolled from the production line into warehousing. The most crucial task in the bundling and warehousing process is the forming of the rolled sections, which involves initially compressing the loose rolled sections into round bundles for bundling by the baler and further tightening. The baler's ability to quickly produce neat, secure, and strong bundles significantly impacts the warehousing of the rolled sections. During the baling process, the bundling former aligns and bundles the rolled sections, and temporarily tightens the width and height of the bundle using hydraulic or pneumatic clamping devices. This makes the cross-sections of multiple rolled sections approach the target bundle shape (such as square or hexagonal), reducing the compression load on the baler. Therefore, the reliability and bundling efficiency of the bundling former significantly affect the bundling quality of the baler and the production line's pace.

[0003] The original bundling and forming device consisted of a hydraulic cylinder, disc spring tie rod, first clamping arm, second clamping arm, and multiple pins. The disc spring tie rod was responsible for resetting the first clamping arm after the rolled workpiece was formed. However, in actual production, the disc spring tie rod suffered frequent damage due to its frequent use. Problems included the disc spring plates breaking under stress, the tie rod pins falling off, and damage to the connecting threads. Furthermore, the disc spring tie rod was installed at the bottom of the forming device, with roller tracks and roller track guards at the front and rear, and the bundling machine's wire feeding guide groove between the guards, making replacement and maintenance of the disc spring tie rod difficult. These problems seriously affected the normal operation of the rolling mill production line. Utility Model Content

[0027] like Figures 1 to 4 As shown, this utility model provides a baling and forming device, including a mounting base 1, a first clamping arm 2, a second clamping arm 7, and a counterweight assembly. The first clamping arm 2 and the second clamping arm 7 are arranged opposite to each other on the mounting base 1 and can be closer to or further away from each other. The counterweight assembly includes a support frame 5, a counterweight block 8, and a connecting line 4. The support frame 5 is mounted on the mounting base 1 and is used to lay the connecting line 4. The counterweight block 8 is connected to the first clamping arm 2 through the connecting line 4 and is used to move the first clamping arm 2 away from the second clamping arm 7, so that the first clamping arm 2 returns to its original position. By setting the counterweight assembly on the first clamping arm 2, when the first clamping arm 2 moves closer to the second clamping arm 7, it can automatically return to its original position through the counterweight assembly, eliminating the problem of easy damage and inconvenience in maintenance of the disc spring pull rod when the existing baling and forming device returns to its original position. At the same time, the counterweight assembly has a simple structure and is easy to modify and assemble on existing baling and forming devices, and has good practicality and economic value.

[0028] The counterweight assembly also includes a first pulley 3, which is mounted on the support frame 5 and located on the path of the connecting line 4. The first pulley 3 is positioned directly above the first arm 2 when the first arm 2 and the second arm 7 are moving away from each other. The support frame 5 has a clearance opening corresponding to the installation position of the first pulley 3. The connecting line 4 is connected to the first arm 2 through the clearance opening, which allows the connecting line 4 to pass when the first arm 2 approaches or moves away from the second arm 7. The first pulley 3 is used to change the laying direction of the connecting line 4 so that the connecting line 4 connects to the counterweight 8. By setting the first pulley 3, the connecting line 4 slides on the first pulley 3 and changes direction, which can prevent friction between the connecting line 4 and the support frame 5 during its movement on the support frame 5, thus avoiding wear of the connecting line 4.

[0029] The counterweight assembly also includes a second pulley 6, which is mounted on the support frame 5 and located on the laying path of the connecting line 4. The second pulley 6 is used to change the laying direction of the connecting line 4 so that the counterweight 8 is suspended in the air. By setting the second pulley 6, the laying direction of the connecting line 4 can be changed while avoiding friction between the connecting line 4 and the support frame 5, thus preventing wear of the connecting line 4.

[0030] In this embodiment, the first clamping arm 2 and the second clamping arm 7 are sequentially arranged on the mounting base 1 along the first direction, and the first pulley 3 and the second pulley 6 are sequentially arranged on the support frame 5 along the first direction. The mounting base 1 is Y-shaped, and the first clamping arm 2 and the second clamping arm 7 are respectively arranged at the upper support of the Y-shape of the mounting base 1. The support frame 5 is inverted U-shaped, and both ends of the support frame 5 are respectively connected to the ends of the upper support of the mounting bracket. The first pulley 3 and the second pulley 6 are arranged sequentially along the first direction, which avoids increasing the width of the support frame 5, and the structure is stable and easy to assemble. In some embodiments, the mounting base 1 has a protruding part for mounting the support frame 5. The protruding part is elongated and extends along the second direction, which intersects with the first direction. The arrangement of the support frame 5 can be adjusted according to specific usage needs.

[0031] like Figure 2 and Figure 3 As shown, the counterweight assembly and the first arm 2 are connected by a connecting assembly 9. The connecting assembly 9 includes a connecting shaft and a connecting sleeve sleeved on the connecting shaft. In this embodiment, the connecting shaft is connected to the connecting line 4, and the connecting sleeve is fixedly connected to the first arm 2. In some embodiments, the connecting shaft is connected to the first arm 2, and the connecting sleeve is connected to the connecting line 4. Through the cooperation between the connecting shaft and the connecting sleeve, the connection between the first arm 2 and the counterweight 8 can be automatically adjusted according to the angle between the connecting line 4 and the first arm 2 when the first arm 2 is relatively close to or far from the second arm 7, thus avoiding the situation where the connecting line 4 repeatedly winds and wears at the connection between the first arm 2 and the counterweight 8.

[0032] In this embodiment, the connecting sleeve is located at the end of the first arm 2 near the support frame 5. This arrangement prevents the connecting wire 4 from interfering with the mounting base 1 when it moves with the first arm 2.

[0033] like Figure 4 The second clamping arm 7 is rotatably connected to the mounting base 1 via a rotating connection point. The second clamping arm 7 has a connecting end connected to the mounting base 1 and a functional end that is close to or away from the first clamping arm 2. The bundling and forming device also includes a linkage rod 10. The middle part of the linkage rod 10 is rotatably mounted on the mounting base 1. One end of the linkage rod 10 is slidably connected to the first clamping arm 2, and the other end of the linkage rod 10 is rotatably connected to a rotating connecting rod 12. One end of the rotating connecting rod 12 is rotatably connected to the linkage rod 10, and the other end of the rotating connecting rod 12 is rotatably connected to the second clamping arm 7. The connection position of the rotating connecting rod 12 and the second clamping arm 7 is located on the side of the second clamping arm 7 closer to the functional end via the rotating connection point. This configuration allows the first clamping arm 2 and the second clamping arm 7 to move closer to or further away simultaneously by controlling the linkage rod 10. In this embodiment, a hydraulic cylinder 11 is provided at the end of the linkage 10 near the first clamping arm 2. The hydraulic cylinder 11 is used to drive the linkage 10 to slide relative to the first clamping arm 2, and to drive the first clamping arm 2 to rotate relative to the mounting base 1, and to drive the second clamping arm 7 to rotate relative to the mounting base 1, so that the functional ends of the first clamping arm 2 and the second clamping arm 7 move closer or further apart. The hydraulic cylinder 11 has the advantages of high energy efficiency, simple structure, and uniform thrust. In some embodiments, a linear motor is provided on the side of the linkage 10 near the first clamping arm 2, and the linear motor is used to drive the linkage 10 to slide relative to the first clamping arm 2. The driving component that drives the linkage 10 can be adjusted according to actual usage requirements.

[0034] This utility model also provides a finishing and forming device for a double high-strength bar production line, including the bundling and forming device as described above.

[0035] In summary, by installing a counterweight assembly on the first arm 2, the first arm 2 can automatically reset itself when it approaches the second arm 7. This eliminates the problem of easy damage and inconvenience in maintenance of the disc spring lever when the existing baler resets via the disc spring lever. Furthermore, the counterweight assembly has a simple structure and is easy to modify and assemble on existing baler units, demonstrating good practicality and economic value.

[0036] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
