Description

Technical Field

[0001] The utility model relates to the technical field of pipe bending, and more specifically, to a pipe bending device for a condenser. Background Art

[0002] Condenser tube is a pipe used in refrigeration system to transport refrigerant from condenser to other equipment or system. It is usually made of materials such as copper or aluminum, with good thermal conductivity and corrosion resistance. In the refrigeration system, the function of condenser tube is to cool the high temperature and high pressure refrigerant gas and turn it into liquid for further use. Therefore, condenser tube needs to withstand high temperature and high pressure working environment, and also need to ensure good thermal conductivity and corrosion resistance.

[0003] A general pipe bending device places the pipe under the bending head and above the bending table, drives the bending head down through a hydraulic rod, and applies downward pressure to the pipe through the hydraulic rod to bend the pipe.

Therefore, when the bending head reaches the surface of the pipe, the pipe deviates, affecting the bending of the pipe and making the bending efficiency low. Therefore, it needs to be modified and optimized. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] The clamping mechanism is fixedly installed above the sliding mechanism; it clamps the condenser tube that needs to be bent;

[0037] The clamping mechanism includes a motor 9 fixedly installed above the sliding mechanism, a bolt 8 fixedly installed above the transmission shaft of the motor 9, a clamp plate 1 6 and a clamp plate 2 7 movably sleeved above the bolt 8, the clamp plate 2 7 is located below the clamp plate 1 6, and the clamp plate 2 7 and the clamp plate 1 6 are internally provided with threads, a movable groove 10 is fixedly opened inside the concave block 5, and the clamp plate 2 7 and the clamp plate 1 6 are movably connected to the movable groove 10.

[0038] When the staff needs to bend the condenser tube, first place the condenser tube on the bending table, and then start the motor 9. When the motor 9 is started, it will drive the bolt 8 to rotate. When the bolt 8 rotates, since the connection between the splint 1 6 and the splint 2 7 and the bolt 8 is also provided with threads, the splint 1 6 and the splint 2 7 will move toward each other along the moving groove 10 as the bolt 8 rotates. When the condenser tube is bent, the motor 9 is started to make the motor 9 drive the bolt 8 to rotate in the opposite direction. When the bolt 8 rotates in the opposite direction, the splint 1 6 and the splint 2 7 will move in opposite directions.

[0039] By placing the condenser tube on top of the bending table and then starting the motor 9, the bolt 8 will be driven to rotate. As the bolt 8 rotates, the clamp plate 1 6 and the clamp plate 2 7 will move toward each other along the movable groove 10. When the condenser tube is bent, the motor 9 is started to drive the bolt 8 to rotate in the opposite direction, which will cause the clamp plate 1 6 and the clamp plate 2 7 to move back to each other, and the condenser tube can be taken out.

One side of the groove 20 is fixedly connected to one end of the second spring 22, and the other end of the second spring 22 is fixedly connected to the baffle in the middle of the second fixing rod 21.

[0045] When the staff needs to replace the bending block and bending head of the bending table, by pulling the fixing rod 13, the baffle in the middle of the fixing rod 13 is moved from one end inside the shell 12 to the other end, the bottom of the fixing rod 13 will move backward, and the spring 14 will be squeezed. Then take the bending table, and then pull the fixing rod 21 to move the baffle in the middle of the fixing rod 21 from one end of the groove 20 to the other end of the groove 20, so that the bottom of the fixing rod 21 moves backward, and the spring 22 will be compressed at this time. Then take the bending head. When the bending head is replaced, by loosening the fixing rod 21, the spring 22 will drive the bottom of the fixing rod 21 back to its original position due to its elasticity.

[0046] By pulling the fixing rod 13, the bottom of the fixing rod 13 moves backward, the spring 14 will be squeezed, and then the bending head can be taken to replace the bending table, and then the fixing rod 21 is pulled to move the bottom of the fixing rod 21 backward to replace the bending head. Compared with the traditional device, the device can replace the bending table by pulling the fixing rod 13, and the bending head can be replaced by pulling the fixing rod 21, which increases the service life of the entire device, avoids the need to replace the entire device due to damage to the bending head, and improves the use efficiency of the device.

[0050] The pipe bending mechanism includes a hydraulic rod 18 fixedly installed below the second bracket 17 , a bending head 19 fixedly installed below the hydraulic rod 18 , and a bending table 15 fixedly installed above the table top 11 .

[0053] There are two sets of sliding mechanisms, both of which are fixedly disposed below the recessed block 5 and extend to the interior of the base 1 .

[0056] The condenser tube can be clamped better, avoiding the situation where there is only one set of clamping mechanisms, which makes the clamping of the condenser tube unstable.

[0058] When the replacement is completed, the bending table can be better fixed to make it more secure.

[0059] The working principle and use process of this utility model:

[0060] When the staff needs to bend the condenser tube, first place the condenser tube on the bending table, and then start the motor 9. When the motor 9 is started, it will drive the bolt 8 to rotate. When the bolt 8 rotates, since the connection between the splint 1 6 and the splint 2 7 and the bolt 8 is also provided with threads, the splint 1 6 and the splint 2 7 will move toward each other along the moving groove 10 as the bolt 8 rotates. When the condenser tube is bent, the motor 9 is started to make the motor 9 drive the bolt 8 to rotate in the opposite direction. When the bolt 8 rotates in the opposite direction, the splint 1 6 and the splint 2 7 will move in opposite directions.

[0061] When the staff needs to replace the bending block and bending head of the bending table, by pulling the fixing rod 13, the baffle in the middle of the fixing rod 13 is moved from one end inside the shell 12 to the other end, the bottom of the fixing rod 13 will move backward, and the spring 14 will be squeezed. Then take the bending table, and then pull the fixing rod 21 to move the baffle in the middle of the fixing rod 21 from one end of the groove 20 to the other end of the groove 20, so that the bottom of the fixing rod 21 moves backward, and the spring 22 will be compressed at this time. Then take the bending head. When the bending head is replaced, by loosening the fixing rod 21, the spring 22 will drive the bottom of the fixing rod 21 back to its original position due to its elasticity.
