Description

Technical Field

[0001] The utility model relates to the technical field of forming machines, in particular to a square tube forming machine. Background Art

[0002] Ceiling square tubes refer to a type of tube used in building ceilings, which is generally square or rectangular in cross-section. They are usually called square tubes. When processing square tubes, they usually need to be processed and formed using a forming machine. At present, when processing, the existing square tube forming machines on the market need to have a concave strip groove on one side of the formed plate. Then the forming machine cannot complete the processing in one go. It is necessary to process the main shape of the square tube and then process the strip groove at that position separately. This will affect the overall processing efficiency. Therefore, it is necessary to design a square tube forming machine. Utility Model Content

[0026] In this embodiment, during processing, the plate is placed on the lower mold 8, and then the hydraulic cylinder 6 is started. The hydraulic cylinder 6 controls the upper mold 7 to press down, and the square tube is preformed by the upper mold 7, the lower mold 8 and the forming table 2. The plate forming is set into two parts. The plate is preformed first, and then a specific position is processed. In this way, if a groove needs to be set on the other side of the plate or other positions in the later stage, the preformed plate can still be used to avoid waste.

[0027] like Figure 4 and Figure 5 As shown, a conveying mechanism is arranged at both ends of the side of the forming table 2 away from the frame 3, and the conveying mechanism includes a first bracket 14 and a second bracket 15. The first bracket 14 is symmetrically arranged on both sides of the processing table 1 close to the third bracket 4, and the second bracket 15 is symmetrically arranged on the side of the processing table 1 away from the third bracket 4. The ends of the first bracket 14 and the second bracket 15 are both movably mounted with a first guide roller 16. The top of the forming table 2 is located between the first bracket 14 and the second bracket 15 and is provided with two shaft brackets 17. The tops of the two shaft brackets 17 are both movably mounted with a support roller 16. Roller 18, pressure roller 19 is movably installed at the top of the first bracket 14 and the second bracket 15, a transmission shell 20 is arranged outside the top of the two second brackets 15, two pressure rollers 19 are located inside the transmission shell 20 and a synchronous wheel 21 is arranged at one end, the two synchronous wheels 21 are movably connected through a synchronous belt, a motor 22 is arranged outside one side of the transmission shell 20, and the output shaft of the motor 22 is fixedly connected to any one of the synchronous wheels 21, and second guide rollers 23 are movably installed in the middle of both sides of the shaft frame 17, and the second guide rollers 23 are opposite to the first guide rollers 16;

[0028] In this embodiment, the upper and lower surfaces of the middle part of the preformed square tube are guided by the roller 18 and the pressure roller 19, and the two sides are guided by the first guide roller 16 and the second guide roller 23. During transportation, the motor 22 controls the synchronous wheel 21 at the end to rotate, and the synchronous wheel 21 at this position drives the synchronous wheel 21 at the other end to rotate synchronously through the synchronous belt, thereby controlling the two pressure rollers 19 to roll and transport the preformed square tube to one side. In this way, the displacement of the preformed square tube during transportation can be avoided.

[0029] like Figure 3 and Figure 5 As shown, the third bracket 4 is arranged at the middle of the left end of the processing table 1 close to the forming table 2, and an extrusion plate 5 is movably installed at the lower side of the third bracket 4 close to the forming table 2 through a rotating shaft, and a stopper 24 is arranged at the side of the forming table 2 close to the extrusion plate 5, and a groove is arranged at the side of the stopper 24 close to the extrusion plate 5;

[0030] In this embodiment, when the square tube moves, the lower outer wall on one side is squeezed by the squeezing disk 5, and the inner wall on the same side is supported by the block 24, so that a concave strip groove can be pressed out on the lower outer side of the square tube at this position, so that the square tube of this shape can be processed and formed at one time, thereby improving the processing efficiency.

[0031] Working principle: During processing, the plate is placed on the lower mold 8, and then the hydraulic cylinder 6 is started. The hydraulic cylinder 6 controls the upper mold 7 to press down, and the square tube is preformed through the upper mold 7, the lower mold 8 and the forming table 2. After preforming, the hydraulic cylinder 6 is controlled to rise, and then the preformed square tube is moved to one side until it is inserted between the roller 18 and the pressure roller 19, and then the motor 22 is started. The motor 22 controls the synchronous wheel 21 at the end to rotate. The synchronous wheel 21 at this position drives the synchronous wheel 21 at the other end to rotate synchronously through the synchronous belt, and then controls the two pressure rollers 19 to roll and transport the preformed square tube to one side. While the square tube is moving, the outer wall of one side below is squeezed by the extrusion disk 5, and the inner wall of the same side is supported by the block 24, so that a concave strip groove can be pressed out on the lower outer side of the square tube at this position, so that the square tube of this shape can be processed and formed at one time.
