Description

Technical Field

[0001] The invention relates to the technical field of liquid distribution pipe processing, and in particular to a processing device for a liquid distribution pipe of a heat exchanger of an air source heat pump. Background Art

[0002] Shell and tube heat exchanger is a heat exchanger composed of a group of tube bundles or coils installed in a shell. The two media that transfer heat, one in the tube and the other in the outer shell of the tube, transfer heat through the tube wall. It is generally horizontal and mainly used as the main equipment in the air-conditioning heat pump industry. It can be an evaporator or a condenser. Its heat exchange medium is generally water and a refrigerant (refrigerant). Compared with other forms of heat exchangers (shell and tube heat exchangers, plate heat exchangers, high-efficiency tank heat exchangers, etc.), shell and tube heat exchangers have small water resistance and refrigerant resistance, and obvious price advantages. They are widely used in water-cooled screw units, water source heat pump units, water-cooled cabinet units, industrial chillers, household villa units, modular units, etc.

[0003] In the prior art, when processing the liquid dispensing tube of the heat exchanger, the liquid dispensing tube needs to be bent. The liquid dispensing tube is a waist-shaped tube (refer to Figure 1 ), the waist-shaped tube has a larger contact area with the heat exchange medium than the circular liquid separation tube under the same volume. In the process of bending the waist-shaped tube, the bending column will cause the waist-shaped tube to bend around the fixed column. In the process of bending the waist-shaped tube for a long time, the bending column will tilt. In the subsequent bending process, the bent waist-shaped tube will be twisted (reference Figure 2 ), the heat exchange tube needs to conduct heat, so the tube wall is usually thin. In the process of bending the waist-shaped tube, cracks are easily formed on the surface of the twisted waist-shaped tube. Then in the subsequent heat conduction process, long-term thermal expansion and contraction will cause leakage at the crack position, thereby reducing the service life of the liquid separation tube.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When processing the liquid distribution pipe of the heat exchanger of the air source heat pump, the present invention uses a push plate, a fixing plate, a positioning plate and a guide block to enable the waist-shaped pipe to fit on the surface of the fixing plate and move before bending, thereby ensuring the stability of the waist-shaped pipe before bending, and avoiding that the waist-shaped pipe cannot be in a stable position before bending the waist-shaped pipe, and moves during the bending process, thereby affecting the bending effect of the waist-shaped pipe; and using a fitting tube, the bending column can always fit with the surface of the waist-shaped pipe during the bending process of the waist-shaped pipe, thereby ensuring the smooth bending of the waist-shaped pipe, and avoiding that the bending column and the waist-shaped pipe cannot fit together during the bending process, thereby causing the waist-shaped pipe to be twisted and have small cracks after bending.

Then, in the process of bending the waist-shaped tube, the pushing plate will make the waist-shaped tube fit with the fixed plate under the action of the push plate, ensuring the support of the waist-shaped tube, which is conducive to keeping the waist-shaped tube stable during the bending process, ensuring the smooth bending of the waist-shaped tube, and avoiding the waist-shaped tube located at the pushing plate position from tilting during the bending process of the waist-shaped tube, thereby affecting the normal bending of the waist-shaped tube.

An L-shaped push plate 12 is elastically slidably connected to the surface of the rotating ring 2, and the push plate 12 extends to the upper end position of the bending column 102. A push rod 13 is fixedly connected to the upper end surface of the push plate 12, and the push rod 13 is in contact with the upper end surface of the bending column 102, and the push rod 13 is close to the mounting plate 9.

[0033] The supporting mechanism includes a first supporting plate 14, which is fixedly connected to the upper end of the bending column 102, and the first supporting plate 14 extends to the surface of the workbench 1 after passing over the fitting cylinder 8. The surface of the workbench 1 is provided with an arc groove 15, and the bottom of the first supporting plate 14 slides in the arc groove 15;

[0034] When processing the heat exchanger liquid distribution pipe of the air source heat pump, it is necessary to first push the waist-shaped tube 103 through the fixing plate 4 and the positioning plate 5 toward the side close to the fixing column 101, and the pushing plate 7 will push the waist-shaped tube 103 toward the side close to the fixing plate 4, so that the waist-shaped tube 103 fits with the fixing plate 4, and when the waist-shaped tube 103 moves to the position of the guide block 6, the guide block 6 will squeeze the waist-shaped tube 103 so that the bent and deformed waist-shaped tube 103 can fit with the fixing plate 4, and the guide block 6 can correct the waist-shaped tube 103 together with the fixing plate 4 when the waist-shaped tube 103 passes, which is conducive to making the waist-shaped tube 103 fit on the surface of the fixing plate 4 before bending and moving, ensuring the stability of the waist-shaped tube 103 before bending, and avoiding the waist-shaped tube 103 from being bent. Before bending, the waist-shaped tube 103 cannot be in a stable position and will move during the bending process, thereby affecting the bending effect of the waist-shaped tube 103. Subsequently, the waist-shaped tube 103 is pushed to move so that the fixed column 101 is in an appropriate bending position. When the waist-shaped tube 103 passes between the fixed column 101 and the bending column 102, the fitting tube 8 will be moved to the side close to the bending column 102 under the squeezing action of the waist-shaped tube 103, and the fitting tube 8 will fit with the surface of the waist-shaped tube 103, which is beneficial for the subsequent bending column 102 to bend the waist-shaped tube 103. The fitting tube 8 can always fit with the surface of the waist-shaped tube 103, ensuring the smooth bending of the waist-shaped tube 103 and avoiding the bending column 102 and the waist-shaped tube 103 not being able to fit during the bending process, thereby causing The waist-shaped tube 103 will be twisted and have small cracks after bending. In the subsequent use of the waist-shaped tube 103, thermal expansion and contraction will cause leakage at the twisted position of the waist-shaped tube 103, affecting the normal use of the waist-shaped tube 103. Subsequently, the driving motor 3 drives the rotating disk to rotate, and the rotating disk drives the bending column 102 and the fitting tube 8 to rotate together. The bending column 102 and the fitting tube 8 will bend the waist-shaped tube 103, and the waist-shaped tube 103 will bend around the fixed column 101. During the bending process, the first support plate 14 will support the force direction of the bending column 102, which is beneficial to keep the bending column 102 vertical during the bending process of the waist-shaped tube 103, thereby ensuring the smooth bending of the waist-shaped tube 103 and avoiding bending during a long period of bending. The column 102 will bend and tilt to one side, thereby affecting the normal bending of the waist-shaped tube 103. In the process of continuous turning of the waist-shaped tube 103, the bending column is tilted and cannot be adjusted in time. When the waist-shaped tube 103 continues to bend, the rotating ring 2 will drive the bending column and the fitting tube 8 to move closer to the waist-shaped tube 103, and the fitting tube 8 will fit with the surface of the waist-shaped tube 103. Then, the fitting tube 8 will move closer to the bending column under the action of the waist-shaped tube 103, and the bottom of the fitting tube 8 will contact the bottom of the bending column. A certain gap will be left between the top of the inclined bending column and the fitting tube 8, and the waist-shaped tube 103 will act on the push plate 12 to move, and the push plate 12 will drive the push rod 13 to move together, and the push rod 13 will move out of the range of the mounting plate 9, and the mounting plate 9 will move downward.The filling plate 11 located in the gap between the bending column and the fitting tube 8 will move into the gap to support the bending column and the fitting tube 8, which is beneficial to fill the gap between the upper end and the bending column after the fitting tube 8 and the waist-shaped tube 103 are fitted together when the bending column is tilted to bend the waist-shaped tube 103, ensuring that the filling plate 11 can support the fitting tube 8 when the bending column bends the waist-shaped tube 103, so that the fitting tube 8 can always fit with the waist-shaped tube 103 during the bending process of the waist-shaped tube 103, avoiding the waist-shaped tube 103 from being bent. During the bending process, there is a gap between the bending column and the fitting tube 8, and the fitting tube 8 cannot smoothly bend the waist-shaped tube 103. The waist-shaped tube 103 will still be twisted during the bending process, thereby affecting the subsequent use of the waist-shaped tube 103. Then, when the bending column 102 returns to its original position, the push plate 12 will be separated from the waist-shaped tube 102, and the push plate 12 will drive the push rod 13 to move toward the side close to the mounting plate 9 again. The mounting plate 9 will move upward under the action of the push rod 13, and the filling plate 11 will move out from between the bending column 102 and the fitting tube 8.

[0035] In the process of bending the waist-shaped tube 103, the pushing plate 7 cannot make the waist-shaped tube 103 always fit on the surface of the fixing plate 4. The waist-shaped tube 103 located at the position of the pushing plate 7 will move to one side during the bending process. As a further solution of the present invention, the surface of the pushing plate 7 close to the positioning plate 5 is fixedly connected with two push plates 16, and the two push plates 16 penetrate the positioning plate 5. The positioning plate 5 is elastically slidably connected with a blocking plate 17 on the side away from the pushing plate 7. The blocking plate 17 extends to the position of the fitting tube 8, and two second openings 18 are provided on the surface of the blocking plate 17 corresponding to the positions of the two push plates 16.

[0036] In the process of bending the waist-shaped tube 103, the rotating ring 2 will drive the bending column 102 and the fitting tube 8 to move, and the bending column 102 and the fitting tube 8 will move away from the blocking plate 17, and the blocking plate 17 will move toward the side close to the bending column 102, and the second opening 18 will be staggered with the push plate 16, and the blocking plate 17 will block the push plate 16. Then, in the process of bending the waist-shaped tube 103, the pushing plate 7 will make the waist-shaped tube 103 fit with the fixed plate 4 under the action of the push plate 16, ensuring that the waist-shaped tube 103 is bent. The support is conducive to keeping the waist-shaped tube 103 stable during the bending process, ensuring the smooth bending of the waist-shaped tube 103 and preventing the waist-shaped tube 103 located at the pushing plate 7 from tilting up during the bending process of the waist-shaped tube 103, thereby affecting the normal bending of the waist-shaped tube 103. Subsequently, when the bending column 102 and the fitting tube 8 return to their original positions, the fitting tube 8 pushes the blocking plate 17 to move away from the bending column 102, and the second opening 18 moves to the position of the ejecting plate 16, and the ejecting plate 16 can pass through the second opening 18.

[0037] In the process of bending the waist-shaped tube 103, the bent end is prone to twisting and tilting. As a further solution of the present invention, an L-shaped retaining plate 19 is fixedly connected to the surface of the rotating ring 2, and the retaining plate 19 is located on the side of the fixed column 101 away from the fixed plate 4;

[0038] During the bending process of the waist-shaped tube 103, the bending column 102 will cause the waist-shaped tube 103 to bend around the fixed column 101, and the rotating ring 2 will drive the support plate 19 to rotate together, so that the support plate 19 and the waist-shaped tube 103 during the bending process remain in contact, which is beneficial for the waist-shaped tube 103 to maintain its bent state and reduce the degree of distortion and tilt during the bending process of the waist-shaped tube 103.

[0039] In the process of bending the waist-shaped tube 103, after the waist-shaped tube 103 is pushed between the bending column 102 and the fixed position, a gap will be left between the waist-shaped tube 103 and the workbench 1. As a further solution of the present invention, a pressing plate 20 is elastically slidably connected to the surface of the baffle plate 19, and the pressing plate 20 is located above the waist-shaped tube 103. A soft spacer 21 is fixedly connected to the bottom of the pressing plate 20;

[0040] After the waist-shaped tube 103 is pushed between the fixing plate 4 and the pushing plate 7 to between the bending column 102 and the fixing column 101, the waist-shaped tube 103 needs to pass through the bottom of the pressing plate 20. The waist-shaped tube 103 will contact the surface of the workbench 1 under the action of the pressing plate 20, ensuring that the waist-shaped tube 103 can maintain contact with the workbench 1 during the bending process, and avoiding the waist-shaped tube 103 being unable to bend according to a preset shape due to one side of the waist-shaped tube 103 not being able to bend during the bending process. The spacer 21 can avoid the hard contact of the pressing plate 20 on the waist-shaped tube 103, and prevent the waist-shaped tube 103 from being deformed by the hard contact and pressure of the pressing plate 20, thereby affecting the use of the waist-shaped tube 103.

[0041] During the long-term bending process of the waist-shaped tube 103, the fixed column 101 will tilt. As a further solution of the present invention, the surface of the fixed column 101 is elastically rotatably connected with a second support plate 22, and the surface of the second support plate 22 close to the stop plate 19 is slidably connected with an arc-shaped connecting plate 23, and the connecting plate 23 extends to the surface of the workbench 1 inside the rotating ring 2, and the surface of the workbench 1 is provided with an arc-shaped guiding groove 24, and the end of the guiding groove 24 is bent toward the side close to the fixed column 101, and the connecting plate 23 slides in the guiding groove 24;

[0042] When the waist-shaped tube 103 is bent, the waist-shaped tube 103 will require the fixed column 101 to rotate, and the second support plate 22 can support the fixed column 101 to reduce the deformation of the fixed column 101 during the bending process of the waist-shaped tube 103, thereby ensuring the bending of the waist-shaped tube 103. Then, when the bending angle of the waist-shaped tube 103 is large, the stop plate 19 will move to the position of the connecting plate 23, and the stop plate 19 will push the connecting plate 23 and the second support plate 22 to rotate, ensuring that the second support plate 22 can support the fixed column 101 at different angles as the waist-shaped tube 103 is bent. When the connecting plate 23 moves to the end of the guide groove 24, the connecting plate 23 will move to the side close to the fixed column 101 under the action of the guide groove 24 to leave the range of the stop plate 19, and will not affect the movement of the stop plate 19.

[0043] In the process of bending the waist-shaped tube 103, the angle at which the bending column 102 bends the waist-shaped tube 103 cannot be determined. As a further solution of the present invention, a plurality of limiting grooves 25 are provided on the inner wall side of the arc-shaped groove 15, and the limiting blocks 26 are slidably connected in the limiting grooves 25;

[0044] During the process of bending the waist-shaped tube 103, the limit blocks 26 at different positions are moved into the arc groove 15 according to the required bending angle. Then, during the process of bending the waist-shaped tube 103, the limit blocks 26 will block the first support plate 14, so that the bending column 102 can bend at a fixed angle, thereby ensuring that the waist-shaped tube 103 can bend at a required fixed angle.
