Description

Technical Field

[0001] This application relates to the field of sheet metal processing, and in particular to a quick-connect structure and a roll forming machine. Background Technology

[0002] Currently, roll forming machines are required for processing certain types of sheet metal with specific cross-sections.

[0003] In related technologies, roll forming machines include a drive assembly and a pressure roller assembly. The drive assembly powers the pressure roller assembly to form sheets with specific cross-sections. Specifically, the drive component of the drive assembly is connected to the connecting shaft of the pressure roller assembly using a telescopic universal coupling, and the telescopic universal coupling is fixed to the connecting shaft via a flange. By replacing different pressure roller assemblies, sheets with different cross-sections can be formed.

[0004] However, in practical applications, when it is necessary to replace the pressure roller assembly, it is necessary to remove multiple bolts and nuts on the flange to separate the telescopic universal coupling from the connecting shaft, which is a rather troublesome operation and therefore needs to be improved. Utility Model Content

[0005] To facilitate the replacement of the pressure roller assembly, this application provides a quick-connect structure.

[0006] The quick-connection structure provided in this application adopts the following technical solution:

[0007] A quick-connect structure includes a telescopic universal coupling, a connecting member, a connecting shaft, and a change-fit nut; the connecting member includes a connecting post; the connecting post is located at one end of the telescopic universal coupling, and the connecting post has an insertion groove along its length and external threads on its circumference; the connecting shaft includes a shaft body and an insertion post; the insertion post is located at one end of the shaft body and is inserted into the insertion groove; the change-fit nut is threaded to the external threads and abuts against the end of the insertion post near the shaft body.

[0008] By adopting the above technical solution, in practical applications, the plug-in post is inserted into the plug-in slot. Then, by rotating the changing nut, since the changing nut is threaded onto the external thread, the changing nut is threaded onto the connecting post, thereby driving the changing nut to move so that the changing nut abuts against the end of the plug-in post near the shaft, thus preventing the changing nut from disengaging from the connecting shaft, thereby achieving stable fixation between the telescopic universal coupling and the connecting shaft. When it is necessary to replace the pressure roller assembly, by rotating the changing nut, the changing nut is disengaged from the connecting post, and then the plug-in post is pulled out of the plug-in slot for replacement. The operation is simple and convenient, thus facilitating the replacement of the pressure roller assembly.

[0009] Preferably, the connector further includes a flange, which is located at one end of the connecting column near the telescopic universal coupling, and the flange is detachably connected to the telescopic universal coupling.

[0010] By adopting the above technical solution and setting a flange, a detachable connection between the connecting parts and the telescopic universal coupling can be achieved, so that the connecting column can be connected to the telescopic universal coupling.

[0011] Preferably, the plug-in post has multiple rounded corners spaced apart along its circumference.

[0012] By adopting the above technical solution and setting multiple rounded corners, it is possible to facilitate the insertion of the plug into the plug slot.

[0013] Preferably, the connecting shaft further includes an abutment ring, which is disposed at one end of the insertion post near the shaft body, and the area of ​​the abutment ring is larger than the area of ​​the insertion post.

[0014] By adopting the above technical solution and setting an abutment ring, the replacement nut can abut more stably, thereby improving the stability of the fixation between the telescopic universal coupling and the connecting shaft.

[0015] Preferably, the connecting shaft further includes a guide block, which is located at the end of the plug-in post away from the shaft body.

[0016] By adopting the above technical solution and setting guide blocks, the plug-in post can be easily inserted into the plug-in slot.

[0017] Preferably, the end of the replacement nut away from the connecting post has a through hole, the area of ​​which is larger than the area of ​​the plug post and is eccentrically positioned.

[0018] By adopting the above technical solution and setting through holes, the installation of the replacement nut can be facilitated.

[0019] Preferably, the quick-connect structure further includes a fastening bolt, which is threaded to the change-fit nut and abuts against the connecting post.

[0020] By adopting the above technical solution and setting fastening bolts to restrict the rotation of the change-type nut, the stability of the telescopic universal coupling and the connecting shaft is further improved.

[0021] Secondly, this application provides a roll forming machine.

[0022] The roll forming machine provided in this application adopts the following technical solution:

[0023] A roll forming machine includes the quick-connect structure described above.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. When it is necessary to replace the pressure roller assembly, the replacement nut is turned to disengage it from the connecting post, and then the insertion post is pulled out of the insertion slot for replacement. The operation is simple and convenient, which facilitates the replacement of the pressure roller assembly.

[0026] 2. By setting an abutment ring, the changing nut can abut more stably, thereby improving the stability of the fixation between the telescopic universal coupling and the connecting shaft;

[0027] 3. Through holes are provided to facilitate the installation of replacement nuts. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a fast connection structure.

[0035] Reference Figure 1 and Figure 2 The quick-connect structure includes a telescopic universal coupling 1, a connector 2, a connecting shaft 3, and a change-type nut 4. The connector 2 includes a connecting post 21, one end of which is installed on one end of the telescopic universal coupling 1. The connecting post 21 has a through insertion groove 211 along its length and an external thread 212 on its circumference.

[0036] Reference Figure 2 and Figure 3 The connecting shaft 3 includes a shaft body 31 and a plug-in post 32. The plug-in post 32 is integrally connected to one end of the shaft body 31 and is inserted into the plug-in groove 211. A change-fit nut 4 is movably inserted through the shaft body 31 and the plug-in post 32. The change-fit nut 4 has an internal thread 41, which is adapted to the external thread 212 to realize the threaded connection between the change-fit nut 4 and the connecting post 21. The change-fit nut 4 abuts against the end of the plug-in post 32 near the shaft body 31.

[0037] In practical applications, the plug-in post 32 is inserted into the plug-in slot 211. Then, by rotating the changing nut 4, which is threadedly connected to the connecting post 21, the changing nut 4 is moved so that it abuts against the end of the plug-in post 32 near the shaft 31, thus preventing the changing nut 4 from disengaging from the connecting shaft 3, thereby achieving a stable fixation between the telescopic universal coupling 1 and the connecting shaft 3.

[0038] When the pressure roller assembly 7 needs to be replaced, it is only necessary to rotate the changing nut 4 to disengage it from the connecting post 21, and then pull the insertion post 32 out of the insertion slot 211 to replace it. The operation is simple and convenient, which facilitates the replacement of the pressure roller assembly 7.

[0039] Reference Figure 1 and Figure 2 In some embodiments, the connecting member 2 further includes a flange 22, which is integrally connected to the end of the connecting column 21 near the telescopic universal coupling 1. The flange 22 is fixedly connected to the telescopic universal coupling 1 by multiple bolts to achieve a detachable connection between the connecting member 2 and the telescopic universal coupling 1, thereby facilitating the connection between the connecting column 21 and the telescopic universal coupling 1. The diameter of the flange 22 is larger than the diameter of the connecting column 21 to improve the stability of the connection with the telescopic universal coupling 1.

[0040] Reference Figure 2 In some embodiments, the plug post 32 is provided with rounded corners 33 at even intervals along its circumference. During the process of plugging the plug post 32 into the plug groove 211, the rounded corners 33 facilitate the plug post 32 to be inserted into the plug groove 211.

[0041] In some embodiments, the connecting shaft 3 further includes an abutment ring 34, which is integrally connected to one end of the insertion post 32 near the shaft body 31. The area of ​​the abutment ring 34 is larger than the area of ​​the insertion post 32, and the changing nut 4 abuts against the abutment ring 34, making the changing nut 4 abut against the abutment ring 34 more stably, thereby improving the stability of the fixation between the telescopic universal coupling 1 and the connecting shaft 3.

[0042] In some embodiments, the connecting shaft 3 further includes a guide block 35, which is a round block. The guide block 35 is integrally connected to the end of the plug-in post 32 away from the shaft 31. The area of ​​the guide block 35 is smaller than the area of ​​the plug-in post 32. Under the guidance of the guide block 35, it is easier for the plug-in post 32 to be inserted into the plug-in slot 211.

[0043] In some embodiments, the end of the change-fit nut 4 away from the connecting post 21 has a through hole 42, the area of ​​which is larger than the area of ​​the insertion post 32, to allow the insertion post 32 and the shaft 31 to pass through. Meanwhile, the insertion post 32 is eccentrically positioned. During installation, the change-fit nut 4 is inserted between the insertion post 32 and the shaft 31, and then rotated. Due to the eccentric positioning of the through hole 42, the change-fit nut 4 abuts against the abutment ring 34, thus facilitating its installation.

[0044] In some embodiments, the quick-connect structure further includes a fastening bolt 5, which is threaded onto the change-fit nut 4 and abuts against the connecting post 21 to restrict the rotation of the change-fit nut 4. This further improves the stability of the fixation between the telescopic universal coupling 1 and the connecting shaft 3.

[0045] The implementation principle of this embodiment is as follows: In practical application, the plug-in post 32 is inserted into the plug-in slot 211. Then, by rotating the changing nut 4, since the changing nut 4 is threadedly connected to the connecting post 21, the changing nut 4 is moved so that the changing nut 4 abuts against the end of the plug-in post 32 near the shaft 31, thereby restricting the changing nut 4 from disengaging from the connecting shaft 3, thus achieving stable fixation between the telescopic universal coupling 1 and the connecting shaft 3.

[0046] When the pressure roller assembly 7 needs to be replaced, it is only necessary to rotate the changing nut 4 to disengage it from the connecting post 21, and then pull the insertion post 32 out of the insertion slot 211 to replace it. The operation is simple and convenient, which facilitates the replacement of the pressure roller assembly 7.

[0047] This application also discloses a roll forming machine.

[0048] Reference Figure 4 The roll forming machine includes a drive assembly 6, a pressure roller assembly 7, and the quick-connect structure described in the above embodiments. The telescopic universal coupling 1 is connected to the drive assembly 6, and the pressure roller assembly 7 is connected to the connecting shaft 3.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
