Description

Technical Field

[0001] The present invention relates to a bending device, and particularly to a stainless steel bending device. Background Art

[0002] Stainless steel is short for stainless acid-resistant steel. Steels that are resistant to weak corrosive media such as air, steam, and water or have stainless properties are called stainless steels; while steels that are resistant to chemical corrosive media (chemical etching such as acids, alkalis, and salts) are called acid-resistant steels.

[0003] When processing stainless steel into various finished products, it is usually necessary to bend the stainless steel. There are many ways to use the bending process. When it is not used to bending at 90°, it is usually necessary to use a hydraulic cylinder to punch holes at the bending place and cut off the waste at the bending place. The existing punching steps are cumbersome. First, it is necessary to punch holes at the top of the stainless steel square tube, and then transfer the stainless steel square tube to another stamping die for secondary punching operation on the stainless steel square tube, which not only increases the labor cost but also reduces the production efficiency.

Detailed implementation manners

[0027] The present invention will be further described below with reference to the drawings and embodiments. Embodiment 1: A stainless steel bending device, such as Figure 1 , Figure 2 and Figure 5 shown in the figures, includes an operating table 1, a connecting frame 2, a support rod 3, a hydraulic cylinder 4, a mounting plate 5, a punching die 6, a return spring 7, a triangular die 10, a second spring 101, a guide rod 102, a connecting plate 11 and a top block 12. The front part on the left side of the operating table 1 is connected to the connecting frame 2 by means of bolt connection. The bottom on the left side of the connecting frame 2 is connected to the hydraulic cylinder 4 by means of bolt connection. The piston rod of the hydraulic cylinder 4 is installed downward. The piston rod of the hydraulic cylinder 4 is connected to the mounting plate 5. The left side of the mounting plate 5 is connected to the support rod 3 by means of welding. The right side of the mounting plate 5 is connected to the connecting plate 11 by means of welding. The left end of the support rod 3 and the bottom of the connecting plate 11 are both connected to the top block 12 by means of welding. The punching die 6 for punching the stainless steel square tube is slidably connected to the mounting plate 5. A return spring 7 is connected between the punching die 6 and the mounting plate 5. Two guide rods 102 are connected to the front side of the top of the operating table 1 by means of welding. The triangular die 10 for punching the stainless steel square tube is slidably connected to the guide rods 102. The top of the triangular die 10 is provided with an inclined surface. The inclined surface at the top of the triangular die 10 is in contact and cooperation with the top block 12. When the top block 12 moves downward, it squeezes the two triangular dies 10 on both sides to approach each other. The two triangular dies 10 are symmetrically installed. The triangular die 10 is in contact with the operating table 1. A second spring 101 is connected between the triangular die 10 and the operating table 1. The second spring 101 is sleeved outside the guide rod 102.

[0028] When using this device, place the stainless steel square tube between two triangular dies 10 on the operating table 1, start the hydraulic cylinder 4, and the piston rod of the hydraulic cylinder 4 pushes the mounting plate 5 downward. The downward movement of the mounting plate 5 drives the punching die 6 and the top block 12 downward. When the punching die 6 contacts the stainless steel square tube, the piston rod of the hydraulic cylinder 4 continues to move downward. Under the extrusion of the stainless steel square tube, the punching die 6 approaches the mounting plate 5, and the return spring 7 will be compressed. At the same time, after the top block 12 contacts the triangular die 10, the top block 12 pushes the triangular die 10 toward the stainless steel square tube, and the second spring 101 is compressed. Under the action of the top blocks 12 on both sides, the stainless steel square tube is clamped. Under the combined clamping force at the same time, the punching die 6 and the triangular die 10 simultaneously perform punching operations on the stainless steel square tube. After the punching operation is completed, start the piston rod of the hydraulic cylinder 4 to retract upward. The punching die 6 separates from the stainless steel square tube, and the top block 12 separates from the triangular die 10. The return spring 7 and the second spring 101 will return to their original positions. The return spring 7 drives the punching die 6 to return to the initial position downward. Under the action of the restoring force of the second spring 101, the triangular die 10 is driven to gradually move away from the stainless steel square tube. Only then can the stainless steel square tube be taken out and bent, optimizing the punching steps and shortening the production operation time.

[0029] Embodiment 2: On the basis of Embodiment 1, as Figure 7 shown, it further includes an extrusion plate 19, a mounting frame 20, a sliding rod 21, a third spring 22, a fourth spring 23, a connecting block 24, a support block 25, a limiting plate 26, a slider 34, a linkage rod 27 and a resisting rod 28. The right side of the bottom of the connecting plate 11 is connected to the extrusion plate 19 by welding. The extrusion plate 19 is installed in an inclined manner. The right rear part of the operating table 1 is connected to the limiting plate 26 and the mounting frame 20 by welding. The limiting plate 26 is located on the right side of the mounting frame 20. The limiting plate 26 is zigzag-shaped. The front end of the limiting plate 26 is closer to the mounting frame 20 than the rear end. A sliding rod 21 is connected to the inside of the mounting frame 20 by welding. A slider 34 is slidably connected to the sliding rod 21. A third spring 22 is connected between the slider 34 and the mounting frame 20. The third spring 22 is sleeved outside the sliding rod 21. The top of the slider 34 is connected to a linkage rod 27. A connecting block 24 is slidably connected to the left side of the slider 34. A fourth spring 23 is connected between the connecting block 24 and the slider 34. The top of the connecting block 24 is connected to the resisting rod 28 by welding. The right end of the resisting rod 28 abuts against the limiting plate 26. A support block 25 is connected to the front side of the connecting block 24 by welding. A groove adapted to the triangular die 10 is formed on the support block 25.

[0030] When the piston rod of the hydraulic cylinder 4 moves downward, the piston rod of the hydraulic cylinder 4 drives the connecting plate 11 to move downward. The downward movement of the connecting plate 11 squeezes the linkage rod 27 to move forward. The forward movement of the linkage rod 27 drives the slider 34 to move along the front end of the slide rod 21, and the third spring 22 will be compressed. At the same time, the linkage rod 27 drives the abutting rod 28 to move along the front side of the limiting plate 26. The forward movement of the abutting rod 28 drives the connecting block 24 and the supporting block 25 to move forward simultaneously. When the abutting rod 28 moves to the front end of the limiting plate 26, the abutting rod 28 will push the connecting block 24 and the supporting block 25 to move leftward to align with the stainless steel square tube, and the fourth spring 23 will be stretched. The supporting block 25 will penetrate into the rear end of the stainless steel square tube. When the punching die 6 and the triangular die 10 perform punching operations on the stainless steel square tube, the supporting block 25 can support the inside of the stainless steel square tube to prevent the stainless steel square tube from collapsing and deforming due to excessive extrusion force during the punching operation. After punching is completed, as the piston rod of the hydraulic cylinder 4 retracts upward, the connecting plate 11 gradually moves upward. The linkage rod 27 loses the extrusion force, and the third spring 22 will move backward and recover. Under the action of the restoring force of the third spring 22, the slider 34 will drive the supporting block 25 to gradually move away from the stainless steel square tube. The supporting block 25 can take out the waste after punching from the stainless steel square tube, and the fourth spring 23 will retract and recover.

[0031] As Figure 3 and Figure 4 shown, it further includes a first cylinder 8, a cutter 81, a first spring 82 and a clamping block 83. The cutter 81 is slidably connected to both the front and rear sides of the punching die 6. A first spring 82 is connected between the cutter 81 and the punching die 6. First cylinders 8 are connected to both the front and rear sides of the punching die 6 by welding. The push rod of the first cylinder 8 is connected to the clamping block 83 by welding. The clamping block 83 contacts the top of the cutter 81. When the piston rod of the hydraulic cylinder 4 moves downward, the first cylinder 8 is started. The push rod of the first cylinder 8 pushes the clamping block 83, and the clamping block 83 clamps the cutter 81 to make the bottom of the cutter 81 horizontal with the bottom of the punching die 6 so as to punch the stainless steel square tube simultaneously. The cutter 81 contacts the supporting block 25. After punching is completed, the push rod of the first cylinder 8 retracts to pull the clamping block 83 to separate the clamping block 83 from the cutter 81. After the cutter 81 loses support, the cutter 81 will move upward, and the first spring 82 will be compressed, thereby being able to prevent the supporting block 25 from being damaged by the cutter 81 to the greatest extent. When the piston rod of the hydraulic cylinder 4 moves upward, the cutter 81 is separated from the supporting block 25, and the first spring 82 will drive the cutter 81 to return to the initial position.

[0032] As Figure 6As shown in the figure, it further includes a first L-shaped plate 15, a first gear set 16, a first rotating shaft 1601, a first motor 17 and a pulley set 18. The left part of the front side of the operating table 1 is fixedly connected with the first L-shaped plate 15. The top of the first L-shaped plate 15 is connected with the first motor 17 by means of bolt connection. Four first rotating shafts 1601 are rotatably connected to the front side of the operating table 1. Two adjacent first rotating shafts 1601 are connected by the first gear set 16. The first motor 17 is connected with one of the first rotating shafts 1601 through a coupling. The two first gear sets 16 are connected by the pulley set 18. When the punching of the stainless steel square tube is completed, the first motor 17 is started to rotate. Under the combined drive of the first motor 17 through the first gear set 16 and the pulley set 18, the first rotating shaft 1601 is driven to rotate. The two adjacent first rotating shafts 1601 rotate to clamp the stainless steel square tube and convey it to the rear side of the operating table 1, so that the stainless steel square tube is far away from the lower side of the hydraulic cylinder 4, which is convenient for taking the stainless steel square tube and performing subsequent process operations.

[0033] As Figure 2 and Figure 8 shown in the figure, it further includes a limit block 9, a second L-shaped plate 29, a second rotating shaft 30, a second motor 31, a second gear set 33, a second cylinder 13 and a top plate 14. The limit block 9 is fixedly connected to the operating table 1. The left part of the rear side of the operating table 1 is connected with the second L-shaped plate 29 by welding. The top of the second L-shaped plate 29 is connected with the second motor 31 by means of bolt connection. Two second rotating shafts 30 are rotatably connected to the rear side of the operating table 1. The second rotating shafts 30 are located on the right side of the second L-shaped plate 29. The two second rotating shafts 30 are connected by the second gear set 33. The output shaft of the second motor 31 is connected with one of the second rotating shafts 30 through a coupling. A through hole is opened on the rear side of the operating table 1. The through hole is located behind the two second rotating shafts 30. The second cylinder 13 is fixedly connected to the bottom of the rear side of the operating table 1. The push rod of the second cylinder 13 is connected with the top plate 14 by welding. The top plate 14 is located inside the through hole. When the stainless steel square tube is conveyed to the rear side of the operating table 1 by the rotation of the first rotating shaft 1601 to clamp the stainless steel square tube, the stainless steel square tube passes through the limit block 9 and is sent between the two second rotating shafts 30. Then the second cylinder 13 is started. The push rod of the second cylinder 13 pushes the top plate 14 to move upward and contact with the stainless steel square tube. As the push rod of the second cylinder 13 continuously pushes the top plate 14 to move upward, the limit block 9 fixes the front end of the stainless steel square tube, so that the punching part of the stainless steel square tube can be bent upward to 90°. Then the push rod of the second cylinder 13 is retracted downward to drive the top plate 14 to move into the through hole of the operating table 1. Furthermore, the second motor 31 is started to rotate. The second motor 31 drives the two second rotating shafts 30 to rotate towards each other through the second gear set 33, so that the stainless steel square tube can be clamped and continue to be conveyed to the rear side of the operating table 1, which is convenient for collecting the stainless steel square tube.

[0034] AsFigure 8 As shown, it further includes a collection box 32. The collection box 32 is placed at the rear side of the operation table 1. When the two second rotating shafts 30 clamp the stainless steel square tube and continue to convey it to the rear side of the operation table 1, the stainless steel square tube will fall into the collection box 32, and the stainless steel square tube can be collected without manual labor, reducing the amount of manual work.

[0035] As Figure 6 and Figure 8 shown, snap rings are provided on both the first rotating shaft 1601 and the second rotating shaft 30. Through the snap rings, the first rotating shaft 1601 and the second rotating shaft 30 can limit the position of the stainless steel square tube when conveying it, making it not easy to deviate, so as to ensure a smoother production process.

[0036] As Figure 2 shown, it further includes a shock pad 35. The shock pad 35 is installed at the bottom of the operation table 1. The shock pad 35 is made of rubber. When using this device, the machine is in a long-term vibration state, which is likely to cause components such as bolts inside the machine to fall off. Through the shock pad 35, the vibration of the machine is reduced, thereby reducing the frequency of components such as bolts falling off.

[0037] The above embodiments only represent the preferred implementation modes of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
