Description

Technical Field

[0001] This invention relates to the field of stainless steel square tube bending, and in particular to a stainless steel square tube cutting and bending device. Background Technology

[0002] When stainless steel square tubes are bent using traditional bending devices, they become thinner at the bend, and the originally flat side of the tube becomes an inwardly concave arc at the bend, affecting its structural strength. The above problems can be solved by designing and cutting the square tube according to the required bending angle at the point where the tube needs to be bent, and then bending and welding it. However, manual design and cutting is very time-consuming, and the dimensions cut manually are often inaccurate. This cutting method is very inefficient. At present, there is a lack of highly efficient automated cutting and bending equipment for stainless steel square tubes with intelligent control of the bending angle. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this invention discloses a stainless steel square tube cutting and bending device. This invention uses two second main shafts and a cutting wheel, inclinedly positioned between a first turntable and a bending plate, to cut the stainless steel square tube, forming nine V-shaped grooves on the front side of the tube. Repeated operation can form eighteen V-shaped grooves, etc. The outwardly curling bending plate then closes the V-shaped grooves and bends the stainless steel square tube. An external welding device welds and fixes the bending angle at this point. The inclination of the cutting wheel and the number of cutting wheels on the second main shafts can be set as needed to control the number and angle of the V-shaped grooves cut on the stainless steel square tube. This design allows for efficient batch bending of stainless steel square tubes, ensuring that the diameter of the bent stainless steel square tube does not become thinner and the sides do not dent inward, resulting in high bending quality.

[0004] To achieve the aforementioned objective, the present invention employs the following technical solution: A stainless steel square tube cutting and bending device includes a first support block, a second support block, a third support block, and a third support block. The first support block is equipped with a rotating mechanism, the second support block is equipped with a bending mechanism, a cutting mechanism is provided between the first and second support blocks, and a third support block is provided behind the first and second support blocks.

The output end of the second motor on the right is connected to a second spindle via a coupling. The right end of the second spindle is rotatably connected to the second turntable. Several cutting wheels are equidistantly connected to the side of the second spindle via keys.

[0008] A fixed rod is fixed above the middle section between the first and second turntables, and several levers are fixed at equal intervals at the upper end of the fixed rod.

[0017] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Combined with appendix Figures 1-6 A stainless steel square tube cutting and bending device includes a first support block 1, a second support block 2, a third support block 5 and a third support block 6. The first support block 1 is provided with a rotating mechanism, the second support block 2 is provided with a bending mechanism, a cutting mechanism is provided between the first support block 1 and the second support block 2, and the third support block 5 is provided behind the first support block 1 and the second support block 2. The third support block 5 is provided with a feeding mechanism.

[0019] The rotating mechanism includes a first motor 101, a first motor 101 fixed above a first support block 1, a first main shaft 102 fixed to the right end of the first motor 101, and a first turntable 103 fixed to the right end of the first main shaft 102.

[0020] The bending mechanism includes a second support block 2, the upper end of which is provided with an arc groove 201, and a second turntable 202 is rotatably connected in the arc groove 201. A bending plate 203 is fixed to the right end of the second turntable 202.

[0021] The cutting mechanism includes a second motor 3, which is symmetrically fixed on the first turntable 103. The output end of the second motor 3 is connected to a second spindle 301 via a coupling. The right end of the second spindle 301 is rotatably connected to the second turntable 202. Several cutting wheels 302 are equidistantly connected to the side of the second spindle 301 via keys. Due to the inclination of the second spindle 301, the left end is closer to the first spindle 102 than the right end. The diameter of the cutting wheels 302 decreases from left to right, keeping the outer edge of the cutting wheels 302 parallel to the central axis of the first turntable 103 and the second turntable 202. This allows V-shaped grooves of consistent depth to be cut on the stainless steel square tube 8.

[0022] A fixing rod 4 is fixed above the middle part between the first turntable 103 and the second turntable 202. Several levers 401 are fixed at equal intervals at the upper end of the fixing rod 4. The levers 401 can break off the V-shaped stainless steel material that has not been completely cut off and make it fall.

[0023] The feeding mechanism includes two third support blocks 5. A fixing ring 501 is fixed at the upper end of the third support block 5. A feed pipe 7 is rotatably connected inside the fixing ring 501. A square hole 701 is opened in the middle of the feed pipe 7. An exposed pipe groove 702 is opened on the front side of the feed pipe 7.

[0024] The third support block 6 is fixed behind the third support block 5 on the left side. The third motor 601 is fixed at the upper end of the third support block 6. The output end of the third motor 601 on the left side is connected to the third rotating shaft 602 through a coupling. The left end of the third rotating shaft 602 is fixed with a gear 603. The gear 603 is connected to the left end of the feed pipe 7 through a meshing connection of teeth fixed on the side. Specifically, the feed pipe 7 has several teeth equidistantly formed on the side of the left side of the left end fixing ring 501.

[0025] A stainless steel square tube 8 is slidably connected inside the square hole 701.

[0026] The central axis of the second spindle 301 and the central axis of the first spindle 102 are in the same plane and form an angle of 2.5 degrees, so that the cutting wheel 302, which is vertically fixed on the second spindle 301, can cut a V-shaped groove of 5 degrees on the stainless steel square tube 8.

[0027] The bending plate 203 is rolled outwards, and the connection between the bending plate 203 and the second turntable 202 is located on the rear side of the fixing rod 4. When the bending plate 203 is fixed on the second turntable 202, it occupies a central angle of 45 degrees of the second turntable 202.

[0028] In the stainless steel square tube cutting and bending device described above, the first motor 101 is a stepper motor, which drives the first turntable 103 and the second turntable 202 to rotate, so that the rear cutting wheel 302 is positioned below the feed pipe 7, and the bending plate 203 does not obstruct the right end of the square hole 701. The stainless steel square tube 8 is inserted into the square hole 701, and the stainless steel square tube 8 is pushed from left to right by the external pushing mechanism installed on the left end of the feed pipe 7. After reaching the predetermined position, the external pushing mechanism stops pushing the stainless steel square tube 8 and fixes its position. At this time, the first motor 101 drives the first turntable 103 and the second turntable 202 to rotate in the direction that the rear cutting wheel 302 rotates upward. The second motor... 3. The second spindle 301 drives the cutting wheel 302 to rotate at high speed. When the cutting wheel 302 contacts the stainless steel square tube 8 inserted into the square hole 701, it can cut the front side of the stainless steel square tube 8. Since the second spindle 301 is set at a 2.5-degree angle, after cutting, nine inclined lines at a 2.5-degree angle to the stainless steel square tube 8 will be formed on the front side of the stainless steel square tube 8. The first turntable 103 and the second turntable 202 continue to drive the second spindle 301 and the cutting wheel 302 to rotate, forming nine inclined lines at a 2.5-degree angle to the stainless steel square tube 8 on the front side of the stainless steel square tube 8 again. Since the two sets of cutting wheels 302 are completely symmetrical, the nine inclined cutting lines of each set can converge on the front side of the stainless steel square tube 8, forming nine 5-degree V-shapes. After the cutting groove is created, the first turntable 103 and the second turntable 202 continue to rotate. The fixing rod 4 and the lever 401 can rotate to the front side of the stainless steel square tube 8, bringing the front side of the stainless steel square tube 8 into contact with the cut V-shaped cutting piece, thus completely separating it from the stainless steel square tube 8. Subsequently, the first turntable 103 and the second turntable 202 continue to rotate, causing the bending plate 203 connected to the second turntable 202 to rotate to the opening at the right end of the square hole 701. Then, the third motor 601 starts, driving the gear 603 to rotate. The gear 603 meshes with the teeth on the left side of the feed pipe 7, causing the feed pipe 7 to rotate. The feed pipe 7 drives the stainless steel square tube 8 to rotate 180 degrees, causing the V-shaped groove opening on the stainless steel square tube 8 to turn backward. The external pushing structure connected to the right end of the stainless steel square tube 8 will... The stainless steel square tube 8 is pushed to the right within the square hole 701. After passing through the right end of the square hole 701, the stainless steel square tube 8 comes into contact with the outwardly curled bending plate 203. Under the action of the bending plate 203, the stainless steel square tube 8 bends, and the V-shaped groove cut at the front of the stainless steel square tube 8 automatically closes. The V-shaped groove is welded to fix the bending degree at this time by a welding device installed on the right side of the square hole 701. When all nine V-shaped grooves are closed, the stainless steel square tube 8 can bend 45 degrees. Repeating the above steps can expand the bending to 90 degrees, 135 degrees, and 180 degrees. The bending angle can be selected as needed. After one bending of the stainless steel square tube 8 is completed, the first turntable 103 and the second turntable 202 rotate, causing the bending plate 203 to move upward and no longer block the right end of the square hole 701.The external pushing mechanism pushes the stainless steel square tube 8 to continue moving to the right, keeping the second section requiring bending within the exposed tube groove 702. This process is repeated to continue bending the stainless steel square tube 8. During this process, the gear 603 can mesh with the teeth on the left side of the feed tube 7, causing the feed tube 7 to rotate, thereby rotating the stainless steel square tube 8 to adjust its angle, allowing for cutting and bending operations on the rear and top / bottom sides of the stainless steel square tube 8.
