Description

Technical Field

[0001] The invention relates to the field of stainless steel pipe processing, and more specifically to a bending and forming device for a stainless steel groove pipe fitting. Background Art

[0002] Stainless steel grooved pipe fittings are a kind of accessories used to connect pipes, usually used in water supply and drainage systems, fire protection systems, air conditioning systems, etc. They are made of stainless steel materials, have good corrosion resistance, high temperature resistance and mechanical strength. Stainless steel grooved pipe fittings are connected to the pipeline through grooves. This connection method does not require welding and can be quickly installed and disassembled, while ensuring the sealing and safety of the system.

[0003] There are many types of stainless steel grooved pipe fittings, the most common ones are grooved elbows, grooved tees, grooved crosses and grooved reducers. For grooved elbows: both ends are used to connect pipes to change the direction of the pipes. Before the grooved elbow is formed, the stainless steel pipe is usually bent into the desired shape through a pipe bending process, and then the bent pipe is grooved to form a grooved elbow.

[0004] When the stainless steel pipe is bent into an elbow, its surface will rub against the contact point of the equipment. Although guide wheels are usually set at the contact point to transport and move the stainless steel pipe to reduce friction, this rolling friction method will still have a certain amount of sliding friction, especially in the hot bending process. The heat of the stainless steel pipe after heating will be transferred to the guide wheel, increasing the temperature of the contact point between the stainless steel pipe and the guide wheel. The increase in temperature will increase the friction coefficient, resulting in greater friction. The increased friction will not only cause the surface of the stainless steel pipe to be scratched or damaged, but also affect the surface quality of the final product. Summary of the invention

[0035] See also Figures 1 to 8, a bending and forming device for stainless steel grooved pipe fittings, comprising a support seat 1, the support seat 1 is provided with two groups, and a sector plate 2 is rotatably installed between the two groups of support seats 1;

[0036] Also includes:

[0037] A bending assembly includes a bending plate 3 fixedly mounted on one side of a sector plate 2, a sleeve 4 fixedly mounted on one end of the bending plate 3, a stainless steel tube 8 inserted into the inner cavity of the sleeve 4, a conveying seat 6 arranged below the stainless steel tube 8, the conveying seat 6 is fixedly mounted on two groups of support seats 1, balls 7 are evenly rolledly mounted on the inner cavity of the conveying seat 6, each group of balls 7 is arranged in contact with the stainless steel tube 8, a motor 5 is fixedly mounted on the rear wall of the rear support seat 1, an output end of the motor 5 is fixedly mounted on the sector plate 2, a guide roller 14 is arranged on the side of the conveying seat 6 close to the sleeve 4, the guide roller 14 is rotatably mounted on the two groups of support seats 1, the guide roller 14 is arranged in contact with the bottom of the stainless steel tube 8, and a lubrication assembly is arranged below the guide roller 14.

[0038] The lubrication assembly includes an oil storage tank 15 disposed below the guide roller 14. The oil storage tank 15 is fixedly installed with the two sets of support seats 1. The inner cavity of the oil storage tank 15 is fixedly installed with oil-absorbing cotton 16 adapted to the guide roller 14. The top end of the oil-absorbing cotton 16 is in contact with one side of the guide roller 14.

[0039] A sleeve 9 is fixedly installed on the outside of the sleeve 4, and a threaded rod 11 is rotatably installed in the inner cavity of the sleeve 9. A motor 10 is fixedly installed on the top of the sleeve 9. The output end of the motor 10 is fixedly installed on the threaded rod 11, and two groups of clamps 12 are threadedly installed on the threaded rod 11. The two groups of clamps 12 are slidably installed in the inner cavity of the sleeve 9, and the opposite sides of the two groups of clamps 12 are contacted with the inner cavity of the stainless steel pipe 8.

[0040] First, fix the bottom of the two groups of support seats 1 at the required position, and then the staff will place the heated stainless steel tube 8 in the conveying seat 6. The stainless steel tube 8 will contact each group of balls 7. The conveying seat 6 is set obliquely, and the stainless steel tube 8 will slide to the lower right side on each group of balls 7. During this process, the stainless steel tube 8 will pass through the guide roller 14 and contact the guide roller 14. The stainless steel tube 8 will drive the guide roller 14 to rotate during the sliding process. Then the right end of the stainless steel tube 8 will be inserted into the inner cavity of the sleeve 4. At this time, the left ends of the two groups of splints 12 will be placed in the inner cavity of the stainless steel tube 8. Turn on the second motor 10, the output end of the second motor 10 will drive the threaded rod 11 to rotate, and the thread directions on the two groups of clamping plates 12 are set in opposite directions, so that the threaded rod 11 can drive the two groups of clamping plates 12 to move away from each other. After the two groups of clamping plates 12 contact the inner cavity of the stainless steel tube 8, turn off the second motor 10, so that the two groups of clamping plates 12 can clamp the stainless steel tube 8 and fix it in the inner cavity of the sleeve 4, which plays a fixing role and prevents the stainless steel tube 8 from detaching, which can improve the stability of the subsequent bending of the stainless steel tube 8, and at the same time can clamp the stainless steel tubes 8 of different thicknesses, and the bending work can be carried out at this time;

[0041] Turn on the motor 5, and the output shaft of the motor 5 drives the fan plate 2 to rotate counterclockwise. The fan plate 2 will drive the sleeve 4 to move synchronously through the bending plate 3. Through the setting of the guide roller 14, the stainless steel tube 8 can be guided and conveyed, and the stainless steel tube 8 can be limited when it is bent. During the bending process, the stainless steel tube 8 will fit along the curved side wall of the bending plate 3, and the sleeve 4 can drive the stainless steel tube 8 to bend and fit on the bending plate 3. After the bending is completed, control the motor 5 to drive the fan plate 2 to continue to deflect counterclockwise so that the bottom end of the stainless steel tube 8 is away from the guide roller 14, and then Then, the motor 2 10 is turned on to drive the threaded rod 11 to rotate in the opposite direction. The threaded rod 11 drives the two groups of clamping plates 12 to approach each other and move away from the inner cavity of the stainless steel tube 8. At this time, the fixation of the stainless steel tube 8 is cancelled, and the stainless steel tube 8 can be removed. Then, the motor 1 5 is controlled to drive the fan-shaped plate 2 to rotate clockwise to the initial position, and then the next group of heated stainless steel tubes 8 are placed in the conveying seat 6. The conveying seat 6 and the sleeve 4 are in the same oblique direction, which can realize fast feeding and bending work, thereby realizing continuous bending work, which is more convenient to use and can effectively improve the bending efficiency;

[0042] In the initial state, the oil-absorbing cotton 16 will absorb the lubricating oil in the inner cavity of the oil storage tank 15 and make its surface completely soaked. The inner cavity of the oil-absorbing cotton 16 is fixedly installed with a support, which is used to support the oil-absorbing cotton 16 and is fixedly installed with the inner cavity of the oil storage tank 15. When the heated stainless steel pipe 8 slides through the guide roller 14 in the conveying seat 6, it will drive the guide roller 14 to rotate. At the same time, during the bending process, the force of bending the stainless steel pipe 8 will act on the guide roller 14. The stainless steel pipe 8 will drive the guide roller 14 to rotate during the bending movement. The rotation of the guide roller 14 will cause the oil-absorbing cotton 16 to apply lubricating oil to its surface, which plays a role of automatic application, is more convenient and can reduce manpower. After applying the lubricating oil, the guide roller 14 can dissipate heat itself, and reduce the heat conducted by the stainless steel pipe 8 to the guide roller 14, which can effectively improve the lubrication effect, avoid the contact point temperature of the stainless steel pipe 8 and the guide roller 14 during the hot bending process. Increased friction will be generated, thereby causing the surface of the stainless steel pipe to be scratched or damaged, which can effectively improve the surface quality of the final product.

[0043] like Figure 2 and Figure 3 As shown, elastic rods 20 are evenly fixedly installed on the rotating shafts on the front and rear sides of the guide roller 14, and a ball 21 is rollingly installed on the other end of each group of elastic rods 20. Connecting plates 17 are fixedly installed on the front and rear side walls of the oil storage tank 15, and semicircular blocks 18 are evenly fixedly installed on the side of the two groups of connecting plates 17 close to the ball 21.

[0044] During the bending process, the stainless steel pipe 8 will drive the guide roller 14 to rotate clockwise when it moves to the right side. By setting the oil-absorbing cotton 16, the surface of the guide roller 14 will be scraped while the lubricating oil is applied to the guide roller 14, so that the surface cleanliness of the guide roller 14 can be continuously maintained, and the impurities generated by the air factors during processing and the equipment not being cleaned for a long time can be avoided from falling on the guide roller 14. At the same time, the residual impurities on the surface can be avoided from contacting with the stainless steel pipe 8 to cause scratches or damage, which can effectively improve the surface quality of the stainless steel pipe 8;

[0045] The oil-absorbing cotton 16 will scrape the impurities remaining on the guide roller 14 at the contact position between the oil-absorbing cotton 16 and the guide roller 14. When the guide roller 14 rotates, the rotating shaft on it will drive each group of elastic rods 20 to move synchronously. Each group of elastic rods 20 will drive the rolling balls 21 at the other end to move synchronously. The elastic rods 20 will drive the rolling balls 21 to contact the arc-shaped inclined surface on the connecting plate 17. When the rolling balls 21 pass through the arc-shaped inclined surface on the semicircular block 18, the rolling balls 21 will be squeezed by the semicircular block 18 and the elastic rods 20 will be bent. When the rolling balls 21 are away from the adjacent semicircular block 18, under the action of the elastic rods 20, the elastic rods 20 will restore the initial state and drive the rolling balls 21 Move to the initial position, the elastic force of the elastic rod 20 can make the ball 21 hit the next group of semicircular blocks 18. At this time, during the rotation of the guide roller 14, each group of balls 21 can reciprocate to hit the semicircular blocks 18 and vibrate the connecting plate 17. The shock wave on the connecting plate 17 will be transmitted to the oil-absorbing cotton 16 through the oil storage tank 15. At this time, the impurities remaining on the oil-absorbing cotton 16 can be shaken off, which plays a cleaning role, thereby effectively improving the coating and cleaning effect of the guide roller 14; through the setting of the ball 21, the friction generated during the collision can be reduced, and wear can be avoided, thereby effectively improving the service life of components.

[0046] like Figures 4 to 6 As shown, a fixed cylinder 23 is fixedly installed on the side of the sleeve 9 away from the stainless steel tube 8, and a cold air blower 24 is fixedly installed in the inner cavity of the fixed cylinder 23. A through hole 25 is evenly opened on the side wall of the sleeve 9 close to the fixed cylinder 23. An air storage cavity 26 is opened in the sleeve 4, and the air storage cavity 26 is connected to the inner cavity of the sleeve 9. A cavity 27 is opened in the bending plate 3, and the cavity 27 is connected to the inner cavity of the air storage cavity 26. Exhaust holes 28 are evenly opened on the side of the bending plate 3 away from the fan-shaped plate 2, and each group of exhaust holes 28 is connected to the inner cavity of the cavity 27, and the inner cavity of the cavity 27 is connected to the outside.

[0047] A nozzle 29 is fixedly mounted on one side of the sleeve 9 away from the fixed cylinder 23 . The nozzle 29 is connected to the inner cavity of the sleeve 9 . The nozzle 29 is located below the stainless steel tube 8 .

[0048] After the stainless steel tube 8 is bent, the air cooler 24 is turned on, and the air cooler 24 will blow air into the inner cavity of the fixed tube 23, and the air will be blown to the inner cavity of the sleeve 9 through each group of ports 25, and the gas in the inner cavity of the sleeve 9 will be directly blown out through the inner cavity of the stainless steel tube 8, so that the inner cavity of the stainless steel tube 8 can be cooled. At the same time, the gas in the inner cavity of the sleeve 9 will also be blown to the inner cavity of the gas storage cavity 26, and the gas in the inner cavity of the gas storage cavity 26 will be discharged into the inner cavity of the cavity 27, and the gas in the inner cavity of the cavity 27 will be discharged through each group of exhaust holes 28, so that the bent stainless steel tube 8 and the bending plate 3 can be cooled. The gap between the two parts is used to blow air and cool the outer wall of the stainless steel tube 8. The gas in the cavity 27 that cannot be discharged through the exhaust hole 28 will be directly discharged into the outside, so as to cool the sleeve 4 and the bending plate 3 and the stainless steel tube 8. At the same time, the gas in the inner cavity of the sleeve 9 will also be discharged through the nozzle 29 and directly act on the bending part of the stainless steel tube 8, which can effectively improve the cooling efficiency of the stainless steel tube 8 after bending, thereby effectively improving the forming quality of the stainless steel tube 8 after bending, reducing the elastic recovery ability of the stainless steel tube 8, and reducing its rebound effect.

[0049] like Figure 6 and Figure 7 As shown, a fixed plate 32 is fixedly installed on the top of the fan-shaped plate 2, a cross rod 30 is slidably installed on the fixed plate 32, the cross rod 30 and the bending plate 3 are slidably installed, a telescopic spring 33 is fixedly installed between the cross rod 30 and the fixed plate 32, a push plate 19 is fixedly installed on the end of the cross rod 30 away from the fixed plate 32, and a groove 31 adapted to the push plate 19 is opened on the bending plate 3.

[0050] When the stainless steel tube 8 is bent, the outer wall of the stainless steel tube 8 will fit along the curved side wall of the left side of the bending plate 3. When the stainless steel tube 8 contacts one side of the push plate 19, the stainless steel tube 8 will squeeze the push plate 19. The push plate 19 moves toward the fixed plate 32 on the bending plate 3 through the cross rod 30 and squeezes the telescopic spring 33, so that the push plate 19 can be retracted to the inner cavity of the groove 31. After the stainless steel tube 8 is bent and formed, the control motor 2 10 is controlled to make the two sets of clamps 12 cancel the clamping of the stainless steel tube 8. At this time, under the action of the telescopic spring 33, the telescopic spring 33 restores the initial state and pushes the cross rod 30 to move to the initial position, so that the cross rod 30 can push the bent stainless steel tube 8 out of the sleeve 4 through the push plate 19, so as to quickly remove it, thereby avoiding the situation where the stainless steel tube 8 is stuck in the sleeve 4 and cannot fall off automatically, thereby effectively improving the work efficiency.

[0051] like Figure 3 , Figure 5 and Figure 6As shown, an arc block 22 adapted to the stainless steel pipe 8 is provided on the side of the oil-absorbing cotton 16 away from the guide roller 14 , the arc block 22 is provided in contact with the bottom of the stainless steel pipe 8 , and the arc block 22 is fixedly installed with the oil storage tank 15 .

[0052] A limit block 13 is provided on one side of the stainless steel pipe 8 close to the threaded rod 11 , and the limit block 13 is fixedly installed on one side of the sleeve 4 .

[0053] By setting the arc block 22, the stainless steel tube 8 will pass through the arc block 22 during the sliding process, and the arc block 22 will pre-treat and scrape the bottom of the stainless steel tube 8 to effectively improve the cleanliness of the bottom of the stainless steel tube 8. By setting the limit block 13, after the right end of the stainless steel tube 8 slides into the inner cavity of the sleeve 4, it will contact the limit block 13, and the limit block 13 plays a limiting role.

[0054] like Figure 4 and Figure 5 As shown, the sides of the two groups of clamping plates 12 contacting the inner cavity of the stainless steel tube 8 are both provided with anti-slip textures.

[0055] A filter screen is provided on a side of the fixing cylinder 23 away from the sleeve 9 .

[0056] By setting the anti-slip texture, the friction between the splint 12 and the inner cavity of the stainless steel tube 8 can be increased, thereby improving the clamping and fixing effect of the splint 12 on the stainless steel tube 8. A filter net is set on the side of the fixed tube 23 away from the sleeve 9, so that when the air cooler 24 blows air to absorb external gases into the fixed tube 23, it can filter these gases to prevent impurities from entering.

[0057] Working principle: First, fix the two sets of support seats 1 in the required position, and then place the stainless steel pipe 8 on the conveying seat 6. The stainless steel pipe 8 will automatically slide into the sleeve 9 to realize automatic loading. The motor 2 10 controls the clamping plate 12 to clamp the stainless steel pipe 8, and then the motor 1 5 controls the deflection of the fan plate 2 to realize the bending of the stainless steel pipe 8. The stainless steel pipe 8 will drive the guide roller 14 to rotate during the bending process. The oil-absorbing cotton 16 will automatically apply lubricating oil to the guide roller 14 and scrape off the impurities falling on the guide roller 14. The stainless steel pipe 8 will be pre-treated and cleaned by the arc block 22 before passing through the guide roller 14. The guide roller 14 will rotate through the elastic rod 20 and the ball 21 during the rotation. The cooperation will hit the semicircular block 18 and vibrate the oil-absorbing cotton 16, which can shake off the impurities remaining on the oil-absorbing cotton 16. After the stainless steel pipe 8 is bent, the cold air fan 24 is turned on for blowing. The cold air fan 24 will cool the sleeve 4, the bending plate 3 and the stainless steel pipe 8, so that they can be quickly cooled and formed to avoid the stainless steel pipe 8 from rebounding after bending. When the bent stainless steel pipe 8 needs to be removed, the motor 2 10 is controlled to make the two sets of clamps 12 cancel the clamping of the stainless steel pipe 8. With the cooperation of the telescopic spring 33, the cross rod 30 will push the bent stainless steel pipe 8 off through the push plate 19, and the fan plate 2 is controlled to rotate to the initial position by the motor 1 5 again to realize the bending work of the next stainless steel pipe.
