Description

Technical Field

[0001] This utility model relates to the field of roll forming technology, specifically to a C-shaped steel roll forming machine for square tube processing. Background Technology

[0002] With the acceleration of global industrialization, the demand for square tubes in fields such as building steel structures, new energy photovoltaic brackets, and machinery manufacturing is showing a trend of diversification and high precision. Traditional square tube processing relies on stamping, welding, or hot rolling processes, which have problems such as low efficiency, high energy consumption, and serious material waste. The C-shaped steel roll forming machine is based on the cold bending forming process. It gradually changes the cross-sectional shape of the metal sheet through multiple rolling passes, and can form complex profiles without heating.

[0003] Traditional roll forming machines typically require the upper rollers to gradually plastically bend the metal sheet, which is prone to wear. If not addressed promptly, this will affect the subsequent square tube forming effect, requiring regular replacement or maintenance. However, traditional roll forming machines generally involve a complex disassembly process, thus reducing the equipment's effectiveness. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a C-shaped steel roll forming machine for square tube processing. It solves the problem that in the existing technology, the upper roller of the traditional roll forming machine generally needs to perform gradual plastic bending of the metal sheet, which is prone to wear. If it is not dealt with in time, it will affect the subsequent square tube forming effect and requires regular replacement or maintenance. However, the disassembly process of the traditional roll forming machine is generally complicated, which reduces the equipment's performance.

[0005] According to one aspect, at least one embodiment of the present invention provides a C-shaped steel roll forming machine for square tube processing, including a fixed table, and further comprising:

[0006] Transmission component one, which is fixedly mounted on the top of the fixed platform;

[0008] An auxiliary disassembly assembly is provided, wherein the auxiliary disassembly assembly and the transmission assembly are connected by two threads, and the auxiliary disassembly assembly and the transmission assembly are engaged.

[0009] Preferably, the transmission assembly includes a first upright plate and a second upright plate. The first upright plate and the second upright plate are respectively fixed to the top of the fixed platform near the edges on both sides. A protective baffle is horizontally fixedly welded to one side of the first upright plate near the bottom. A motor is fixedly installed on one side of the first upright plate near the front side of the protective baffle. A first rotating rod is rotatably connected between the inner walls of the front and rear sides of the protective baffle. One end of the first rotating rod extends out of the front side of the protective baffle and is fixedly welded to the output end of the motor. Multiple active bevel gears are equidistantly welded to the outer surface of the first rotating rod in the horizontal direction.

[0010] Preferably, a plurality of second rotating rods are equidistantly arranged horizontally near the bottom of the opposite side of the first and second upright plates. One end of each of the second rotating rods extends out of one side of the first upright plate. A driven bevel gear is fixedly welded to the same end of each of the second rotating rods. The driven bevel gear meshes with the driving bevel gear. A lower roller is fixedly sleeved on the outer edge of each of the second rotating rods near the center by a fixing member. A driving gear is fixedly welded to the outer surface of each of the second rotating rods near the lower roller. The second upright plate is concave. A plurality of engaging grooves are equidistantly opened horizontally near one side of the inner bottom surface of the second upright plate. A plurality of first limiting frames are equidistantly opened horizontally near the top of one side of the first upright plate.

[0011] Preferably, the transmission component two includes a first limiting slider, and multiple first limiting sliders are provided. The multiple first limiting sliders are slidably disposed inside the first limiting frame. A first lead screw is rotatably connected to the top center of the multiple first limiting sliders. The top ends of the multiple first lead screws extend out of the top of the first upright plate and are threadedly connected to the first upright plate.

[0012] Preferably, a third rotating rod is rotatably connected to one side of each of the plurality of first limiting sliders, and a threaded groove is opened on the outer surface of each of the plurality of third rotating rods near one end. An upper roller is fixedly sleeved on the outer surface of each of the plurality of third rotating rods near the center by a fixing member. A driven gear is fixedly welded to the outer surface of each of the plurality of third rotating rods near the first limiting slider, and the driven gear is meshed with the driving gear.

[0013] Preferably, the auxiliary disassembly assembly includes a limiting platform, and multiple limiting platforms are provided. Each of the multiple limiting platforms has a locking block fixedly welded to one side of its bottom center. The limiting platform is limited by locking the locking block and locking the locking groove.

[0014] Preferably, a second limiting frame is provided through one side of each of the plurality of limiting platforms near the center, and a second limiting slider is slidably provided inside each of the plurality of second limiting frames. A second lead screw is rotatably connected to the top center of each of the plurality of second limiting sliders, and the top of each of the plurality of second lead screws extends out of the top of the limiting platform and is threadedly connected to the limiting platform.

[0015] Preferably, the internal rotatable connections of the plurality of second limiting sliders are internally threaded components, the internal threaded components are threaded to one end of the third rotating rod through a threaded groove, and a fastening nut is threaded to the outer surface of the third rotating rod near the internal threaded components through a threaded groove.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] In this utility model, through the meshing of the active bevel gear and the driven bevel gear, as well as the meshing of the active gear and the driven gear, when the motor rotates and outputs, it can synchronously drive the first rotating rod, the second rotating rod, and the third rotating rod to rotate synchronously, thereby realizing the opposing rotation of the upper and lower rollers. By setting multiple sets of upper and lower rollers, steel can be gradually rolled into square tubes.

[0018] When disassembly is required to replace one of the upper rollers, firstly, rotate the first and second lead screws to disengage the driven gear from the driving gear. Then, remove the fastening nut. Next, limit the third rotating rod to prevent it from rotating. Then, use a tool to drive the internal threaded assembly to rotate in the opposite direction. As the internal threaded assembly rotates outward to disassemble, it will drive the limiting platform to slide outward synchronously, causing the locking block to disengage from the locking groove. Finally, the upper roller can be disassembled. The installation process is the same in reverse, making installation and disassembly simple and convenient, facilitating the replacement and maintenance of the upper roller.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-3 As shown, it illustrates a C-shaped steel roll forming machine for square tube processing according to an embodiment of the present invention, including a fixed platform 1, and further comprising:

[0034] Transmission component 12 is fixedly mounted on the top of the fixed platform 1.

[0035] Transmission component 2, 3, is slidingly limited to transmission component 1, 2;

[0036] The auxiliary disassembly component 4 is threadedly connected to the transmission component 2 3, and the auxiliary disassembly component 4 is engaged with the transmission component 1 2.

[0037] The transmission assembly 2 includes a first upright plate 21 and a second upright plate 22. The first upright plate 21 and the second upright plate 22 are respectively fixed to the top of the fixed platform 1 near the edges on both sides. A protective baffle 23 is horizontally fixedly welded to one side of the first upright plate 21 near the bottom. A motor 24 is fixedly installed on one side of the first upright plate 21 near the front side of the protective baffle 23. A first rotating rod 25 is rotatably connected between the inner surfaces of the front and rear sides of the protective baffle 23. One end of the first rotating rod 25 extends out of the front side of the protective baffle 23 and is fixedly welded to the output end of the motor 24. Multiple active bevel gears 26 are equidistantly welded to the outer surface of the first rotating rod 25 in the horizontal direction.

[0038] Multiple second rotating rods 27 are equidistantly arranged in the horizontal direction near the bottom of the opposite side of the first upright plate 21 and the second upright plate 22. One end of each of the multiple second rotating rods 27 extends out of one side of the first upright plate 21. A driven bevel gear 28 is fixedly welded to the same end of each of the multiple second rotating rods 27. The driven bevel gear 28 meshes with the driving bevel gear 26. A lower roller 29 is fixedly sleeved on the outer edge of each of the multiple second rotating rods 27 near the center by a fixing member. A driving gear 210 is fixedly welded to the outer surface of each of the multiple second rotating rods 27 near the lower roller 29. The second upright plate 22 is concave. Multiple engaging grooves 211 are equidistantly opened in the horizontal direction on one side of the inner bottom surface of the second upright plate 22. Multiple first limiting frames 212 are equidistantly opened in the horizontal direction on one side of the first upright plate 21 near the top.

[0039] In this embodiment, starting the motor 24 can drive the first rotating rod 25 and multiple active bevel gears 26 to rotate. Through the meshing of the driven bevel gear 28 with the active bevel gear 26, when the active bevel gear 26 rotates, it can synchronously drive multiple driven bevel gears 28 and the second rotating rod 27 to rotate. The rotation of the second rotating rod 27 can drive the lower roller 29 to rotate synchronously with the active gear 210. The protective baffle 23 prevents the staff from contacting the first rotating rod 25 and the active bevel gear 26, thus achieving the effect of isolation and protection. The locking groove 211 can limit the engagement of the auxiliary disassembly component 4. The first limiting frame 212 can limit the sliding movement of the transmission component 2 3.

[0040] like Figures 1-4 As shown, it illustrates a transmission component 2 3 in another embodiment of the present invention. The transmission component 2 3 includes a first limiting slider 31. Multiple first limiting sliders 31 are provided. The multiple first limiting sliders 31 are slidably disposed inside the first limiting frame 212. A first lead screw 32 is rotatably connected to the top center of the multiple first limiting sliders 31. The top ends of the multiple first lead screws 32 extend out of the top of the first upright plate 21 and are threadedly connected to the first upright plate 21.

[0041] Each of the multiple first limiting sliders 31 is rotatably connected to a third rotating rod 33 on one side. Each of the multiple third rotating rods 33 has a threaded groove 34 near one end on its outer surface. Each of the multiple third rotating rods 33 has an upper roller 35 fixedly sleeved on its outer surface near the center by a fixing member. Each of the multiple third rotating rods 33 has a driven gear 36 fixedly welded to the side of its outer surface near the first limiting slider 31. The driven gear 36 meshes with the driving gear 210.

[0042] In this embodiment, through the sliding arrangement of the first limiting slider 31 and the first limiting frame 212, and the threaded connection between the first lead screw 32 and the first vertical plate 21, the first limiting slider 31 can be made to slide upward synchronously by rotating the handle at the top of the first lead screw 32. Through the meshing arrangement of the driven gear 36 and the driving gear 210, the driving gear 210 can drive the driven gear 36 to rotate during rotation. The rotation of the driven gear 36 can drive the third rotating rod 33 and the upper roller 35 to rotate synchronously, thereby realizing the opposite rotation of the upper roller 35 and the lower roller 29. Through the arrangement of multiple sets of upper rollers 35 and lower rollers 29, the steel can be gradually rolled into square tubes.

[0043] like Figures 1-6 As shown, it illustrates the auxiliary disassembly assembly 4 in another embodiment of the present invention. The auxiliary disassembly assembly 4 includes a limiting platform 41, and multiple limiting platforms 41 are provided. Each of the multiple limiting platforms 41 has a locking block 42 fixedly welded to one side near the bottom center. The limiting platform 41 is locked and limited by locking the locking block 42 with the locking groove 211.

[0044] A second limiting frame 43 is provided through one side of each of the multiple limiting platforms 41 near the center. A second limiting slider 44 is slidably arranged inside each of the multiple second limiting frames 43. A second lead screw 45 is rotatably connected to the top center of each of the multiple second limiting sliders 44. The top of each of the multiple second lead screws 45 extends out of the top of the limiting platform 41 and is threadedly connected to the limiting platform 41. An internal threaded kit 46 is rotatably connected inside each of the multiple second limiting sliders 44. The internal threaded kit 46 is threadedly connected to one end of the third rotating rod 33 through a threaded groove 34. A fastening nut 47 is threadedly connected to the outer surface of the third rotating rod 33 near the internal threaded kit 46 through a threaded groove 34.

[0045] In this embodiment, the sliding engagement of the locking block 42 and the locking groove 211 limits the position of the limiting platform 41, improving stability. By rotating the handle at the top of the second lead screw 45, the second limiting slider 44 can be driven to slide upward synchronously due to the threaded connection between the second lead screw 45 and the limiting platform 41. This, combined with the synchronous rotation of the first lead screw 32, causes the third rotating rod 33, the upper roller 35, and the driven gear 36 to adjust upward, disengaging the driven gear 36 from the driving gear 210. The fastening nut 47 limits the internal thread assembly 46, preventing prolonged rotation of the third rotating rod 33 from causing the internal thread assembly 46 to disengage from the driving gear 210. When the third rotating rod 33 has a threaded groove 34 at one end for demolding, and one of the upper rollers 35 needs to be replaced, firstly, the driven gear 36 and the driving gear 210 are disengaged by rotating the first lead screw 32 and the second lead screw 45. Then, the fastening nut 47 is removed. Next, the third rotating rod 33 is limited to prevent it from rotating. Then, the internal threaded assembly 46 is rotated in the opposite direction by a tool. When the internal threaded assembly 46 is rotated outward to disassemble by passing the stop block at one end of the internal threaded assembly 46, the limiting platform 41 will slide outward synchronously, so that the locking block 42 is disengaged from the locking groove 211. Finally, the upper roller 35 can be disassembled. The reverse installation is the same.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
