Description

Technical Field

[0002] Stainless steel profiles refer to various shaped components made of stainless steel materials, which are used in construction, machinery, automobiles and other engineering fields. The stretching and bending of stainless steel profiles is a process of bending stainless steel profiles into the required shape. This process is widely used in manufacturing, construction and other fields to achieve structural and design requirements. The stretch-bending machine is a device specially used for bending various profiles (such as pipes, square tubes, angle steels, etc.). It can bend straight profiles into various required curves or angles. Conventional stretch-bending machines are divided into double-arm stretch-bending machines and single-arm stretch-bending machines. The double-arm stretch-bending machine applies tension to both ends of the profile through two cylinders, and achieves the stretch-bending effect through cooperation with the mold; the single-arm stretch-bending machine clamps and fixes one end of the profile through an oil cylinder, and the other end of the profile is clamped by the clamp on the mold. The mold applies lateral tension to the profile by rotation to form the profile.

After sliding the slide frame 218 to the corresponding position, it is fixed again by the latch 220. At this time, the staff can place the profile to the rear side of the mold 29 for bending. Since the bending directions of the front side of the mold 29 and the rear side of the mold 29 are opposite, the effect of changing the pulling direction is achieved. For profiles with special processing requirements, the operation steps are simple and there is no need to change the position of the oil cylinder;Through the setting of the bending device 2, when the staff replaces the mold 29, they can replace and fix the mold 29 by pulling out and inserting multiple friction shafts 211.

[0037] For further information, see Figure 7 - Figure 8 , a heat dissipation component 3 is used to assist the heat dissipation of the stretch bending device 2. The heat dissipation component 3 is arranged on the mounting seat 1. The heat dissipation component 3 includes a plurality of No. 1 pulleys 31, and the plurality of No. 1 pulleys 31 are rotatably mounted on the mounting seat 1. The plurality of No. 1 pulleys 31 are located on the inner side of the slewing support bearing 25. The plurality of No. 1 pulleys 31 are arranged in a circular array. A transmission belt 33 is sleeved on the No. 1 pulley 31, and a No. 2 pulley 32 is also sleeved on the transmission belt 33. The No. 2 pulley 32 is rotatably mounted on the mounting seat 1. A fan blade 34 is connected to the top of the No. 2 pulley 32. The plurality of fan blades 34 drive the airflow under the chassis 26 by rotating, and take away part of the heat from the chassis 26, the chuck 28 and the mold 29 through the airflow, thereby achieving a certain heat dissipation effect. The pulleys 32 are arranged in a circular array, and multiple transmission belts 33 are in contact with the inner surface of the slewing support bearing 25. There is a large friction force between the multiple transmission belts 33 and the inner surface of the slewing support bearing 25. When the slewing support bearing 25 rotates, the slewing support bearing 25 uses the friction force to drive the multiple transmission belts 33 to rotate; through the arrangement of the heat dissipation component 3, the multiple fan blades 34 can have a certain heat dissipation effect on the mold 29 by rotating during the bending operation, thereby preventing the mold 29 from generating heat due to continuous friction with the profile after working for a long time. When a lot of heat accumulates, the temperature of the mold 29 will be too high. The mold 29 may expand thermally at high temperature, causing its size and shape to change, thereby affecting the processing accuracy, and may also scald the staff.

[0038] Further, see Fig. 9The lubrication component 4 is used for spraying lubricant on the stainless steel profile. The lubrication component 4 is arranged on the mounting seat 1. The lubrication component 4 includes a ball slide 41. The ball slide 41 is arranged on the output shaft 23. Both ends of the ball slide 41 are slidably connected with the mounting seat 1. The output shaft 23 is provided with an annular bevel groove. The inner wall of the ball slide 41 is slidably connected with the annular bevel groove of the output shaft 23 through the ball. When the output shaft 23 rotates, the ball slide 41 is driven to reciprocate up and down through the annular bevel groove. A pressure plate 42 is connected to the mounting base 1, an air bag 43 and a boost tank 45 are installed on the mounting base 1, and the staff adds lubricant to the boost tank 45 in advance, the top of the air bag 43 contacts the pressure plate 42, an air pipe 44 is installed on the air bag 43, and the end of the air pipe 44 away from the air bag 43 is connected to the boost tank 45, and a rotating pipe 46 is rotatably installed on the boost tank 45, and a nozzle 47 is rotatably connected to the top of the rotating pipe 46, and the nozzle 47 can spray the lubricant on the surface of the profile, so that the profile is before contacting the mold 29. , a layer of lubricant can be attached to the surface to achieve a certain lubrication effect; a connecting rod 48 is hinged on the ball slide 41, and a sliding rod 49 is hinged on the end of the connecting rod 48 away from the ball slide 41. The sliding rod 49 is slidably connected to the mounting seat 1, and a shift fork 410 is connected to the sliding rod 49. A lever 411 is connected to the rotating tube 46, and the lever 411 contacts the shift fork 410. When the shift fork 410 moves back and forth, the lever 411 drives the rotating tube 46 to reciprocate, and the rotating tube 46 drives the nozzle 47 to swing back and forth , thereby increasing the spraying area; through the setting of the lubricating component 4, a layer of lubricant can be sprayed on the profile before it contacts the mold 29, and the lubricant can form a thin film between the profile and the mold 29, thereby reducing the friction during the bending operation, reducing the friction heat and wear generated during the processing, and improving the bending quality of the profile; through the cooperation of the fork 410 and the lever 411, the spray head 47 can reciprocate during spraying, which expands the spraying range and further optimizes the spraying effect.

[0039] For further information, see Fig.10 - Fig.11The cleaning assembly 5 is used to clean the surface of the stainless steel profile. The cleaning assembly 5 is arranged on the bending device 2. The cleaning assembly 5 includes a rotating shaft 51. The rotating shaft 51 is rotatably installed on the support rod 219. The rotating shaft 51 passes through the support rod 219. The outer wall of the rotating shaft 51 is slidably connected with a cleaning roller 52. The cleaning roller 52 is located on the inner wall of the support rod 219. The bottom of the rotating shaft 51 is connected with an umbrella tooth 53. Two residual tooth rings 54 are connected to the edge of the chuck 28. The residual tooth ring 54 contacts the umbrella tooth 53 during the movement. When the chuck 28 rotates, it drives the two residual tooth rings 54 to rotate. When one of the residual tooth rings 54 rotates, it drives the rotating shaft 51 to rotate through the umbrella tooth 53. When the rotating shaft 51 rotates, it drives the cleaning roller 52 to rotate. The cleaning roller 52 cleans one side of the profile that it contacts by rotating. Two scrapers 55 are installed on the inner wall of the support rod 219, and the scrapers 55 are in contact with the cleaning roller 52. Two dust removal openings are opened on the support rod 219, and the two dust removal openings are respectively located under the two scrapers 55. The two scrapers 55 scrape off the dirt attached to the surface of the cleaning roller 52, and the dirt falls to the ground through the two dust removal openings; through the setting of the cleaning component 5, the cleaning roller 52 can clean the outer side of the profile by rotation before the profile is stretched and bent, reducing the dust and impurities falling onto the chuck 28 during the stretching and bending operation, reducing the time for the staff to clean the chuck 28, and reducing the labor intensity of the staff; the two scrapers 55 can continuously clean the cleaning roller 52 to maintain the cleanliness of the surface of the cleaning roller 52, thereby maintaining the cleaning effect.

[0040] With the above structure, the working principle of this case is that the motor 21 and the hydraulic cylinder 214 are both controlled by a remote control, and the motor 21 can rotate in both directions. When the mold 29 is installed, the mold 29 is placed on the chuck 28, and multiple friction shafts 211 are passed through the internal pressure block 210, multiple round holes on the chuck 28, and multiple round holes on the chassis 26, so that the mold 29 is anchored on the chuck 28 through the internal pressure block 210. When the mold 29 needs to be replaced, the multiple friction shafts 211 are pulled out and the above steps are repeated, thereby achieving the effect of quickly replacing the mold 29, with simple operating steps and high replacement efficiency; when performing the stretching and bending operation, one end of the profile is clamped by the No. 2 chuck 217, and the other end of the profile is After the hydraulic cylinder 214 is started, the hydraulic cylinder 214 applies a certain pulling force to one end of the profile through the right-angle rod 215, the second slide 216 and the second clamp 217. After the motor 21 is started, the motor 21 drives the output shaft 23 to rotate through the cycloid reducer 22. The cycloid reducer 22 can increase the torque by reducing the speed. When the output shaft 23 rotates, it drives the gear 24 to rotate. The gear 24 drives the slewing support bearing 25 to rotate on the mounting seat 1 through the multiple teeth on the slewing support bearing 25. The slewing support bearing 25 drives the chassis 26 to rotate through multiple round tubes. When the mold 29 is not installed, the chassis 26 can be driven by multiple short shafts 27. The chuck 28 is driven to rotate. Since the multiple short shafts 27 can move slightly at the bottom of the chuck 28, the chassis 26 first drives the multiple short shafts 27 to rotate a certain angle before driving the chuck 28 to rotate. When the mold 29 is installed, since the multiple friction shafts 211 are interspersed between the chuck 28 and the chassis 26, after the chassis 26 rotates slightly, the multiple friction shafts 211 are stuck between the chuck 28 and the chassis 26, so that the chassis 26 drives the chuck 28 to rotate through the multiple friction shafts 211, so that the chassis 26 and the chuck 28 apply horizontal pressure in two directions to the friction shafts 211, thereby increasing the friction between the chassis 26 and the chuck 28 and the friction shafts 211. The friction shafts 211 are temporarily difficult to slide up and down, thereby achieving the effect of fixing the mold 29, making the mold 29 relatively stable during the bending operation. When the chuck 28 rotates, the mold 29 is driven to rotate through the multiple friction shafts 211. The mold 29 cooperates with the No. 1 clamp 213 to keep the side of the profile close to the surface of the mold 29. When the mold 29 rotates, the profile is bent. At the same time, the hydraulic cylinder 214 contracts and pushes the profile to the right during the bending process to complete the bending operation. While the profile is being bent, the support rod 219 can apply a supporting force to the side of the profile to prevent the unbent part of the profile from being deformed by the tensile force transmitted from the bending part during the bending process.When the bending direction needs to be changed, the staff slides the No. 2 chuck 217 to the other end of the No. 2 slide 216, starts the motor 21 to rotate the chuck 28 180 degrees, then turns off the motor 21, slides the No. 1 chuck 213 on the No. 1 slide 212 to the corresponding position, pulls out the latch 220, and the support rod 219 can slide on the sliding frame 218. After sliding the sliding frame 218 to the corresponding position, it is fixed again by the latch 220. At this time, the staff can place the profile on the back side of the mold 29 for bending. Since the bending directions of the front side of the mold 29 and the back side of the mold 29 are opposite, the effect of changing the pulling direction is achieved. It is suitable for profiles with special processing requirements, the operation steps are simple, and there is no need to replace the cylinder position; through the setting of the bending device 2, when the staff replaces the mold 29, they can replace and fix the mold 29 by pulling out and inserting multiple friction shafts 211. The replacement steps are simple, which shortens the working time and speeds up the working process; when the staff changes the bending direction, they can achieve reversal by rotating the chuck 28 and sliding the No. 1 clamp 213, the No. 2 clamp 217 and the support rod 219. The operation steps are simple and fast, which improves the working efficiency; when the profile is bent, the support rod 219 can support the side of the profile to avoid deformation of the unbent part of the profile; through the cooperation of the cycloid reducer 22 and the slewing support bearing 25, the torque is increased and the power of the bending device 2 is improved. ;

[0041] Since there is a large friction force between the multiple transmission belts 33 and the inner surface of the slewing support bearing 25, when the slewing support bearing 25 rotates, the slewing support bearing 25 uses the friction force to drive the multiple transmission belts 33 to rotate. When the multiple transmission belts 33 rotate, they respectively drive the multiple No. 1 pulleys 31 and the No. 2 pulleys 32 to rotate. When the multiple No. 2 pulleys 32 rotate, they drive the multiple fan blades 34 to rotate. The multiple fan blades 34 drive the air flow under the chassis 26 by rotating, and take away part of the heat from the chassis 26, the chuck 28 and the mold 29 through the air flow, thereby achieving a certain heat dissipation effect; through the setting of the heat dissipation component 3, the multiple fan blades 34 can play a certain heat dissipation effect on the mold 29 by rotating during the bending operation, so as to avoid the mold 29 from generating heat due to continuous friction with the profile after working for a long time. When the heat accumulates more, the temperature of the mold 29 will be too high. The mold 29 may expand thermally at high temperature, causing its size and shape to change, thereby affecting the processing accuracy, and may also scald the staff.

[0042] The staff adds lubricant to the boost tank 45 in advance. When the output shaft 23 rotates, the ball slide 41 is driven to move up and down through the annular inclined groove. The ball slide 41 drives the pressure plate 42 to move synchronously. When the pressure plate 42 moves up and down, it will repeatedly squeeze the air bag 43. When the air bag 43 is squeezed, the air bag 43 injects air into the boost tank 45 through the air pipe 44. The boost tank 45 transports the lubricant to the nozzle 47 through the rotating tube 46 according to the positive pressure principle. The nozzle 47 sprays the lubricant onto the surface of the profile, so that a layer of lubricant can adhere to the surface of the profile before it contacts the mold 29, thereby achieving a certain lubrication effect. While the ball slide 41 is reciprocating up and down, the ball slide 41 drives the slide rod 49 to slide left and right through the connecting rod 48. The slide rod 49 replaces the dial The fork 410 reciprocates left and right. When the fork 410 reciprocates, the lever 411 drives the rotating tube 46 to rotate reciprocally, and the rotating tube 46 drives the spray head 47 to swing back and forth, thereby increasing the spraying area. After changing the bending direction, the staff rotates the spray head 47 to adjust the spraying angle of the spray head 47; through the setting of the lubricating component 4, the profile can be sprayed with a layer of lubricant before contacting the mold 29. The lubricant can form a thin film between the profile and the mold 29, thereby reducing the friction during the bending operation, reducing the friction heat and wear generated during the processing, and improving the bending quality of the profile; through the cooperation of the fork 410 and the lever 411, the spray head 47 can swing back and forth during spraying, which expands the spraying range and further optimizes the spraying effect.

[0043] During the bending operation, the staff usually attaches a layer of protective film on the surface of the mold 29 to prevent surface wear when the profile is bent. The side of the profile that is not in contact with the mold 29 generates a pull rope during bending. When there is dirt such as mud on the surface of the profile, the mud will fall onto the chuck 28 after the profile is stretched. As the use time increases, more impurities will accumulate on the chuck 28, which requires regular cleaning by the staff. Since the chuck 28 is a porous structure, it is inconvenient to clean it. When the chuck 28 rotates, it drives the two residual tooth rings 54 to rotate. When one of the residual tooth rings 54 rotates, it drives the rotating shaft 51 to rotate through the bevel teeth 53. When the rotating shaft 51 rotates, it drives the cleaning roller 52 to rotate. The cleaning roller 52 cleans the side of the profile that it contacts by rotating. The profile is cleaned before it is bent. The rotating shaft 51 is configured to be able to lift a small After a certain distance, the bevel gear 53 and the residual tooth ring 54 are disengaged after the rotating shaft 51 is lifted. When the bending direction is changed, the support rod 219 is moved after the rotating shaft 51 is lifted. After the chuck 28 rotates, the other residual tooth ring 54 contacts the bevel gear 53. While the cleaning roller 52 is rotating, the two scrapers 55 scrape off the dirt attached to the surface of the cleaning roller 52, and the dirt falls to the ground through two dust dropping openings. Through the setting of the cleaning component 5, the cleaning roller 52 can clean the outer side of the profile by rotating before the profile is bent, reducing the dust and impurities that fall onto the chuck 28 during the bending operation, reducing the time for the staff to clean the chuck 28, and reducing the labor intensity of the staff; the two scrapers 55 can continuously clean the cleaning roller 52 to keep the cleanliness of the surface of the cleaning roller 52, thereby maintaining the cleaning effect.
