Description

Technical Field

[0001] The invention discloses a racing car metal pipe bending and shaping device, belonging to the technical field of metal pipe forming. Background Art

[0002] The frame is an important base component in a racing car, supporting and connecting the various system assemblies of the racing car to keep them in a relatively correct position. At the same time, the frame also bears the load from the inside of the racing car and the impact from the tires through the suspension, so the frame must have sufficient strength and rigidity. In order to make the frame meet this requirement, the frame is usually made of metal pipes, so that when the racing car is impacted, its deformation degree can be reduced, thereby protecting the safety of the driver. In order to conform to the shape of the car body and avoid the design of other components, a large number of metal bent pipes are used in the frame. The manufacture of metal bent pipes is generally processed by pipe bending equipment, but when bending metal pipes, they will be concavely deformed due to the force of the bending die, resulting in the cross-section of the bent part of the metal pipe not being a complete circle, which will cause stress concentration at this position, weakening the strength and rigidity of the metal pipe, and thus affecting the overall performance of the frame.

[0021] like Figure 1-Figure 6As shown, a racing metal pipe bending and shaping device comprises an upper template 8 and a lower template 1, a rotating shaft 14 is fixedly installed on one side of the upper template 8, and both ends of the rotating shaft 14 are rotatably connected to the middle part of the lower template 1, and the upper and lower sides of the upper template 8 are provided with first molding grooves 6, and the top surface of the lower template 1 has multiple groups of second molding grooves 11 symmetrically arranged, and the lower template 1 is provided with a first power component for driving the upper template 8 to flip 180°. After the upper template 8 flips 180°, the first molding groove 6 and the second molding groove 11 are molded together, and two limiting columns 7 are provided on the end of the upper template 8 away from the rotating shaft 14, and a locking mechanism 12 is provided on the lower template 1 to lock and limit the limiting columns 7 to prevent the upper template 8 from flipping. The lower template 1 corresponds to the second molding groove A first inflatable component 3 and a second inflatable component 2 are respectively arranged on both sides of 11. The first inflatable component 3 and the second inflatable component 2 have the same structure and are arranged side by side. The first inflatable component 3 includes a sliding seat 29, an inflatable joint 24 and a sealing joint 10. The inflatable joint 24 and the sealing joint 10 are respectively fixed on the two sliding seats 29. The sliding seat 29 is an L-shaped structure, and the lower end is slidably arranged in the lower template 1. A second power component 13 is arranged in the lower template 1. The second power component 13 is used to allow the sliding seats 29 on the same side of the first inflatable component 3 and the second inflatable component 2 to slide in opposite directions, and the two sliding seats 29 in the first inflatable component 3 slide in opposite directions driven by the second power component 13.

[0022] The first power assembly includes a first motor 18, a first transmission shaft 15 and a first driving gear 19. Two first driven gears 9 are arranged on the rotating shaft 14. The first transmission shaft 15 is rotatably installed in the lower template 1, and one end of the first transmission shaft 15 is fixedly connected to the first motor 18. Two first driving gears 19 are arranged, and the first driving gears 19 are fixed on the first transmission shaft 15. The first driving gear 19 is meshed with the first driven gear 9. The first motor 18 drives the first rotating shaft to rotate, so that the first driving gear 19 drives the first driven gear 9 to rotate, so that the rotating shaft 14 drives the upper template 8 to flip 180°, so that the first molding groove 6 and the second molding groove 11 are molded to clamp the metal elbow.

[0023] The second power assembly 13 includes a transmission gear 20, a second transmission shaft 22, a limit block 34 and a driving member 17. A toothed block 25 that cooperates with the transmission gear 20 is provided on the sliding seat 29. The toothed blocks 25 on the two sliding seats 29 on the same side are meshed with the same transmission gear 20. The limit block 34 is fixed to the lower template 1 by bolts. The middle part of the second transmission shaft 22 is threadedly connected to the limit block 34, and the first transmission shaft 15 has a first limit portion 36 that is slidably arranged with the transmission gear 20. The driving member 17 is installed in the middle part of the lower template 1 and is used to drive the two second transmission shafts 22 to rotate in opposite directions. The driving member 17 includes a second motor 30, a second driving gear 31, a second driven gear 32, a first driving pulley 27, and a first driven pulley The first driven pulley 21 and the first belt 26 are each provided with two first driving pulleys 27, the first driven pulley 21 and the first belt 26. A fixing plate 33 for mounting the second motor 30 is provided on the lower template 1. The second driving gear 31 and the second driven gear 32 are both provided with a fixing shaft 28. The two first driving pulleys 27 are fixed on the fixing shaft 28. One end of the fixing shaft 28 connected to the second driving gear 31 is fixedly connected to the output shaft of the second motor 30. A limiting sleeve 35 is fixedly installed on the limiting block 34. An annular protrusion 37 is provided at one end of the first driven pulley 21. The annular protrusion 37 is rotatably installed in the limiting sleeve 35. The first belt 26 is sleeved on the outer sides of the first driving pulley 27 and the first driven pulley 21. The second transmission shaft 22 is provided with a first driven pulley. The second limiting portion 38 of the pulley 21 slides, and when the second motor 30 drives the second driving gear 31 and the second driven gear 32 to rotate, the second belt 43 drives the two second transmission shafts 22 to rotate in the opposite direction. Since the middle part of the second transmission shaft 22 is threadedly connected to the limiting block 34, and the two ends of the second transmission shaft 22 are respectively slidably arranged with the transmission gear 20 and the first driven pulley 21 by the first limiting portion 36 and the second limiting portion 38, when the first driven pulley 21 rotates, the second transmission shaft 22 can be driven to rotate, so that a knob occurs between the second transmission shaft 22 and the limiting block 34, and the two ends of the second transmission shaft 22 can slide in the transmission gear 20 and the second driven pulley 40. At the same time, the second transmission shaft 22 drives the transmission gear 20 to rotate, relying on The meshing of the transmission gear 20 and the toothed block 25 causes the sliding seat 29 to start sliding. Since the two transmission gears 20 rotate in opposite directions driven by the second driving gear 31 and the second driven gear 32, the two sliding seats 29 in the first inflatable component 3 are close to each other to seal the two ends of the metal elbow. Subsequently, the gas is introduced into the metal elbow through the inflatable joint 24 by the external inflatable pipe, and the gas pressure is used to exert an outward expansion force on the metal elbow to achieve the shaping effect, while the two sliding seats 29 in the second inflatable component 2 slide in a direction away from each other, so that another group of metal elbows can be loaded and unloaded. The actions of the first inflatable component 3 and the second inflatable component 2 can be performed alternately, thereby effectively improving the shaping efficiency of the metal elbow.

[0024] The locking mechanism 12 includes a rotating disk 5, a third transmission shaft 23 and a third power assembly. Two third transmission shafts 23 are provided, and the third transmission shafts 23 are rotatably connected to the lower template 1. Four rotating disks 5 are provided, and two rotating disks 5 are fixed on the third transmission shaft 23. A notch 4 and an extension 41 are provided on the rotating disk 5. A slide groove 44 for sliding the limit column 7 is provided between the extension 41 and the rotating disk 5. The width of the entrance end of the slide groove 44 is greater than the diameter of the limit column 7. The third power assembly is installed in the middle of the lower template 1 and is used to drive the two third transmission shafts 23 to rotate in the same direction. The third power assembly can drive the two third transmission shafts 23 to rotate, so that the rotating disk 5 The movable disk 5 rotates. In the initial situation, after the upper template 8 flips 180°, the limiting column 7 moves synchronously with the upper template 8 and can be flipped into the notch 4 of the rotating disk 5. Then the rotating disk 5 is driven by the third power component to rotate, so that the limiting column 7 rotates a certain angle along the slide groove 44. In this way, the limiting column 7 cannot escape the obstruction of the extension part 41 and the flipping of the upper template 8 is restricted. The upper template 8 and the lower template 1 can be locked, so that when the metal bend is inflated by the first inflatable component 3 or the second inflatable component 2, the metal bend will not open the mold between the upper template 8 and the lower template 1 due to the force generated by the air pressure, thereby ensuring that the metal bend can be smoothly shaped.

[0025] The third power assembly includes a third motor 39, a fourth transmission shaft 16, a second active pulley 42, a second driven pulley 40 and a second belt 43. The fourth transmission shaft 16 is rotatably installed in the lower template 1. The output shaft of the third motor 39 is fixedly connected to the fourth transmission shaft 16. The second active pulley 42 is fixed on the fourth transmission shaft 16. The second driven pulley 40 is fixed on the third transmission shaft 23. The second belt 43 is sleeved on the outer side of the second active pulley 42 and the second driven pulley 40. The third motor 39 drives the fourth transmission shaft 16 to rotate, so that the second active pulley 42 drives the second driven pulley 40 to rotate. In this way, the third transmission shaft 23 drives the two rotating disks 5 to rotate, so that the rotating disk 5 rotates clockwise or counterclockwise by a certain angle, and the upper template 8 can be smoothly turned over or locked with the lower template 1. A boss 45 is provided on the side of the rotating disk 5 close to the lower template 1. The boss 45 can leave a certain gap between the rotating disk 5 and the lower template 1. When the upper template 8 is turned over, it will not interfere with the rotating disk 5.

[0026] Working principle: one group of metal bends is placed in the second forming groove 11 of the lower template 1, and then the first power component drives the upper template 8 to flip 180°, and then the first forming groove 6 and the second forming groove 11 are molded together to clamp the metal bend. The first forming groove 6 and the second forming groove 11 are formed by profiling according to the fact that the cross-section of each position of the metal bend is a circle. Then the third power component drives the rotating disk 5 to rotate a certain angle, so that the limit column 7 on the upper template 8 slides along the slide groove 44, so that the extension part 41 blocks the flipping of the upper template 8, and then the driving member 17 drives the two second transmission shafts 22 and the transmission gear 20 to rotate in the opposite direction, so that the transmission gear 20 drives the sliding seats 29 in the first inflatable component 3 and the second inflatable component 2 to slide in the opposite direction, and the two sliding seats 29 in the first inflatable component 3 are close to each other, so that The inflation joint 24 and the sealing joint 10 seal the two ends of the metal elbow, and the gas is introduced into the metal elbow by the external inflation pipe connected to the inflation joint 24, thereby relying on other forces to generate pressure on the metal elbow, so that the shape of the metal elbow fits with the first forming groove 6 and the second forming groove 11 to achieve the shaping effect, thereby reducing the concave deformation and stress concentration of the metal elbow during bending, and making the strength of the metal elbow better. While one group of metal elbows is being shaped, another group of metal elbows can be loaded and unloaded, which can effectively improve the processing efficiency of the metal elbows. After the shaping of one group of metal elbows is completed, the locking mechanism 12 drives the rotating disk 5 to rotate in the opposite direction, so that the limit column 7 slides out of the slide groove 44, thereby contacting the flipping limit of the upper template 8, and preparing for the shaping of the next group of metal elbows.
