Description

Technical Field

[0001] This utility model belongs to the field of cold bending forming technology, and in particular relates to a cold bending forming mechanism for strip steel. Background Technology

[0002] Cold bending is a plastic forming method that uses thin metal sheets or coils as raw materials. Multiple sets of cold bending forming rollers, each with a specific shape, are used to progressively compress and bend the metal raw material, resulting in a product with a uniform cross-section. Cold bending typically requires multiple sets of forming rollers. However, during the transfer from one set of forming rollers to the next, resistance during the forming process and the inherent offset of the forming rollers themselves can cause the sheet metal to shift during bending, resulting in dimensional deviations that affect subsequent use and lead to wasted costs. Furthermore, the sheet metal's own weight can also cause offset during transport, easily resulting in wasted costs. Summary of the Invention

[0003] In view of this, the present invention aims to propose a strip cold bending forming mechanism to solve the problem that the sheet metal shifts during the sheet metal conveying and bending processes, resulting in dimensional deviations and wasted costs.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] Furthermore, the anti-deviation device includes a mounting bracket, a limiting shaft, and an adjusting screw. The surface of the mounting bracket is provided with an elongated hole, and two limiting shafts are inserted into the elongated hole. An adjusting screw is fixedly connected to the bottom end of each limiting shaft. The outer periphery of the adjusting screw is threadedly connected to the side of the mounting bracket, and the two adjusting screws are arranged opposite to each other.

[0007] Furthermore, the feeding guide device includes a second support assembly, an upper guide roller, and a lower guide roller. The second support assembly includes a second bracket and a second slider. A second slider is rotatably connected to each side of the upper guide roller, and a second bracket is rotatably connected to each side of the lower guide roller. Each second bracket is provided with a second groove, and a second slider is provided in the second groove. The second slider is slidably connected to the second groove. A second bolt is provided on the second slider. The second bolt passes through the second bracket and the second slider from top to bottom, and is rotatably connected to the second bracket and threadedly connected to the second slider. The upper guide roller and the lower guide roller are arranged parallel to each other, and the strip is located between the upper guide roller and the lower guide roller.

[0008] Furthermore, the feeding guide device also includes a positioning component, which includes multiple horizontal plates, horizontal bars, and positioning shafts.

[0026] like Figures 1-4As shown, a strip cold bending forming mechanism includes a base 1, on which a feeding guide device 2, multiple cold bending forming devices 3, and an anti-deviation device 4 are arranged. The feeding guide device 2 is located at the front end of the cold bending forming device 3, and the anti-deviation device 4 is located between the multiple cold bending forming devices 3. The cold bending forming device 3 includes a first support assembly 31, an upper pressure roller 32, and a lower pressure roller 33. The first support assembly 31 includes a first bracket 311 and a first slider 312. A first slider 312 is rotatably connected to each side of the upper pressure roller 32, and a first bracket 311 is rotatably connected to each side of the lower pressure roller 33. Each first bracket 311 is provided with a first groove. A first slider 312 is provided in a groove and is slidably connected to the first groove. A first bolt 313 is provided on the first slider 312. The first bolt 313 passes through the first bracket 311 and the first slider 312 from top to bottom, and is threadedly connected to the first slider 312 and rotatably connected to the first bracket 311. The upper pressure roller 32 and the lower pressure roller 33 are arranged parallel to each other, and the strip is located between the upper pressure roller 32 and the lower pressure roller 33. The anti-deviation device 4 includes a mounting frame 41, a limiting rotating shaft 42 and an adjusting screw 43. The surface of the mounting frame 41 is provided with an elongated hole, and two limiting rotating shafts 42 are inserted into the elongated hole. The bottom end of each limiting rotating shaft 42 is fixed. An adjusting screw 43 is connected to the outside of the mounting bracket 41 via a threaded connection, and the two adjusting screws 43 are arranged opposite each other. Each adjusting screw 43 has a limit nut at its free end for fixing and locking the adjusting screw 43. The feed guide device 2 includes two second support assemblies 21 on both sides, an upper guide roller 22, and a lower guide roller 23. The second support assembly 21 includes a second bracket 211 and a second slider 212. A second slider 212 is rotatably connected to each side of the upper guide roller 22, and a second bracket 211 is rotatably connected to each side of the lower guide roller 23. Each second bracket 211 has a second groove. A second slider 212 is provided, which is slidably connected to a second groove. A second bolt 213 is provided on the second slider 212. The second bolt 213 passes through the second bracket 211 and the second slider 212 from top to bottom, and is rotatably connected to the second bracket 211 and threadedly connected to the second slider 212. The upper guide roller 22 and the lower guide roller 23 are arranged parallel to each other, and the strip is located between the upper guide roller 22 and the lower guide roller 23. The second support assembly 21 has the same structure as the first support assembly 31. The feeding guide device 2 also includes a positioning assembly 24, which includes multiple horizontal plates 241, horizontal bars 242, and positioning rotating shafts 243.A horizontal plate 241 is disposed on one side of a first support 311, and two horizontal plates 241 are disposed parallel to each other vertically on each first support 311. A crossbar 242 is disposed on each of the two opposing horizontal plates 241. Positioning shafts 243 are respectively disposed at both ends of the crossbar 242. The upper and lower fixed shafts of the positioning shafts 243 are respectively cross-connected to each crossbar 242, and the positioning shafts 243 can move along the crossbars. The middle of the positioning shaft 243 is a rotatable "I"-shaped structural shaft. The axial direction of the positioning shaft 243 is perpendicular to the strip steel conveying direction. Fixing bolts 244 are respectively disposed on the fixed shafts at both ends of the positioning shaft 243. The fixing bolts 244 are threadedly connected to the positioning shaft 243, and one end of the fixing bolt 244 abuts against the crossbar 242 located on the fixed shaft.

[0027] During implementation, first loosen each fixing bolt 244, adjust the position of the positioning shaft 243 on the crossbar 242 according to the width of the strip, and pass the strip to be produced through the "I"-shaped structure shaft between the two positioning shafts 243, so that the strip contacts the positioning shaft 243. Then tighten the fixing bolts 244 to fix the positioning shaft 243, thereby positioning the strip left and right. Adjust the distance between the upper guide roller 22 and the lower guide roller 23 by the second bolt 213, so that the strip passes through the upper guide roller 22 and the lower guide roller 23. The guide roller 23 passes through the middle, clamping the strip steel between the upper guide roller 22 and the lower guide roller 23, thereby vertically positioning the strip steel. A drive motor can be installed at either end of the lower guide roller 23 to drive the lower guide roller 23 to rotate, thereby driving the strip steel forward. The strip steel continues to be conveyed forward between the upper pressure roller 32 and the lower pressure roller 33. Multiple sets of first support components 31, upper pressure roller 32, and lower pressure roller 33 are arranged in parallel according to the type of welded pipe to be formed. The upper pressure roller 32 is adjusted by setting the first bolt 313. The upper pressure roller 32 is fixed at a suitable position with the lower pressure roller 33 by tightening the first bolt 313. A positioning nut is set on the first bolt 313 for locking, ensuring the stability of the upper pressure roller 32 and ensuring forming accuracy. After processing and forming by multiple sets of upper pressure rollers 32 and lower pressure rollers 33, an anti-deviation device 4 is set parallel to each other between multiple sets of first support components 31. By setting an adjusting screw 43, the distance between the two limit rotating shafts 42 is adjusted so that the sheet metal conveyed by each set of upper pressure rollers 32 and lower pressure rollers 33 during the forming process abuts against the outer periphery of the positioning rotating shaft 42. This avoids the deviation caused by resistance and the deviation of the upper pressure rollers 32 and lower pressure rollers 33 during the forming process, ensuring the consistency of the forming process and ensuring forming quality. Multiple sets of second support components 21, upper guide rollers 22, and lower guide rollers 23 are set between the feeding guide device 2 and the cold bending forming device 3, which can level the strip steel and ensure the flatness of the strip steel, thereby ensuring the consistency of the quality of the strip steel extrusion forming process.

[0028] like Figure 3As shown, the feeding guide device 2 also includes an auxiliary roller 25. The auxiliary roller 25 is disposed on the side of the first bracket 311 away from the positioning component 24 and is rotatably connected to the first bracket 311. The auxiliary roller 25 is close to the lower guide roller 23 and parallel to the lower guide roller 23, and is used to support the conveyed strip steel. Since the strip steel will fall downwards during the transmission process due to its own weight, the auxiliary roller 25 can support the strip steel and avoid the deviation caused by the weight of the strip steel during the movement process, so as not to affect subsequent production. Multiple sets of auxiliary rollers 25 can be arranged in parallel to ensure stable conveying. The outer end face of the groove of the first bracket 311 is provided with a scale to confirm the moving distance of the first slider 34. The adjustment height of the upper pressure roller 12 during the production of different types of steel pipes can be known through the scale value. The next production can be directly set to the specified scale, saving debugging time and improving production efficiency.

[0029] The working principle of a strip steel cold bending forming mechanism: When using this cold bending forming mechanism, the position of the positioning shaft 243 on the crossbar 242 is set by the fixing bolt 244. The strip steel passes through the "I"-shaped structure shaft between the two positioning shafts 243, so that the strip steel contacts the positioning shaft 243, thereby positioning the strip steel left and right. The strip steel continues to pass forward between the upper guide roller 22 and the lower guide roller 23. The distance between the upper guide roller 22 and the lower guide roller 23 is adjusted by the second bolt 213, so that the upper guide roller 22 and the lower guide roller 23 clamp the strip steel, thereby positioning the strip steel vertically. The strip steel continues... The material is conveyed forward between the upper pressure roller 32 and the lower pressure roller 33. The appropriate position between the upper pressure roller 32 and the lower pressure roller 33 is adjusted by setting the first bolt 313, and the first bolt 313 is tightened for fixation. An anti-deviation device 4 is set parallel to each other among multiple sets of first support components 31. The distance between the two limit rotating shafts 42 is adjusted by setting the adjusting screw 43, so that the plate conveyed by each set of upper pressure rollers 32 and lower pressure rollers 33 during the forming process abuts against the outer periphery of the positioning rotating shaft 42. The plate is processed and formed by multiple sets of upper pressure rollers 32 and lower pressure rollers 33 and limit rotating shafts 42, ensuring the consistency of the forming process.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
