Description

Technical Field

[0001] The invention relates to the technical field of pipe bending processing, in particular to a device for processing liquid storage pipe bending. Background Art

[0002] In the manufacturing process of household air conditioner compressor accumulators, steel elbows are one of the key components used to store and transport refrigerant. Traditional pipe bending processes typically use specially annealed carbon steel raw material pipes. Through the overall annealing treatment, the steel pipes are reduced in stress to improve plasticity and facilitate subsequent bending and forming. However, this process has the following drawbacks:

[0003] 1. High material cost: Traditional processes require the use of special carbon steel materials that have undergone pre-annealing treatment, and the cost of raw materials is relatively high.

[0004] 2. Strength loss and deformation risk: Overall annealing will reduce the overall strength of the steel pipe, causing the pipe fittings to be easily deformed after bending, affecting the quality of the finished product.

[0005] 3. Low process efficiency: Traditional processing requires lengthy processing lines for each processing step of pipe fittings. There are problems of low efficiency in cleaning, drying and transporting pipe fittings. The process is cumbersome, and annealing and processing are carried out in steps, resulting in low production efficiency.

[0006] To address these issues, existing technologies have attempted to employ a localized annealing process, heating only the bends to preserve the strength of the unannealed areas. However, existing equipment struggles to achieve precise localized annealing and efficient automated processing, particularly with technical bottlenecks in pipe transport, positioning, and multi-process coordination.

[0029] Beneficial effects of the present invention:

[0030] 1. Reduce material costs by using ordinary carbon steel pipes instead of special annealed carbon steel raw materials, and only perform local annealing on the bent parts to retain the high strength of the unannealed areas and reduce material costs.

[0031] 2. Improve product strength and precision. The localized annealing process (high-frequency induction heating) precisely controls the heating area, avoiding the strength loss caused by overall annealing. The pipe is less likely to deform after bending, and the finished product has higher dimensional stability. The processing components use a multi-roller coordinated bending and drill bit forming process to ensure that the bend angle and port size meet assembly requirements.

[0032] 3. Optimize process flow and improve production efficiency. The coordinated layout of the No. 1 and No. 2 transfer assemblies and the four-station indexing plate enables automated flow of pipes between loading, pre-treatment, annealing, cooling, processing, post-processing, and unloading, reducing manual intervention. The clamping and unlocking mechanisms work together to ensure stable grip and rapid release of pipes during transport and transfer, improving restocking efficiency. The No. 1 and No. 2 transfer assemblies utilize a multi-station fixture design to simultaneously complete the bidirectional transfer of pipes between the transfer line and the indexing plate, shortening cycle time.

[0033] 4. The equipment is highly integrated and offers excellent space utilization. The four-station indexing plate integrates annealing, processing, and transfer stations. Combined with the high-frequency induction heating furnace and processing components on the fixed platen, this system enables integrated processing of local annealing and bending, reducing the equipment's footprint. The sunken synchronous belt section of the transmission assembly places the cleaning, drying, and cooling boxes directly below the transmission path, eliminating the need for additional transfer mechanisms and simplifying the structure.

[0034] 5. Highly adaptable and scalable, the transverse / vertical end-forming mechanism in the processing assembly allows for interchangeable drill bit types (e.g., reaming, tapping) to accommodate different pipe end processing techniques. The modular design of the indexing plate and transmission assembly facilitates adjustments to the workstation sequence or the addition of new processes to meet diverse production needs.

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0048] Example 1

[0049] See also Figure 1 、 Figure 6 A liquid storage elbow processing equipment includes a loading station 101, a pre-processing station 102, an annealing station 103, a cooling station 104, a processing station 105, a post-processing station 106, and a blanking station 107 arranged along the processing sequence of the pipe 8.

[0050] It also includes a No. 1 transmission component 201, a No. 2 transmission component 202, a four-station indexing plate 3, an annealing component 4, and a processing component 5. The front side end of the No. 1 transmission component 201 is provided with a loading station 101 and an unloading station 107. The pre-processing station 102 and the post-processing station 106 are provided below the middle section of the No. 1 transmission component 201. The four-station indexing plate 3 is arranged between the No. 1 transmission component 201 and the No. 2 transmission component 202.

[0051] It also includes a transfer component No. 1 601 and a transfer component No. 2 602. Annealing stations 103, processing stations 105, and transfer stations No. 1 301 and 2 302 are evenly arranged on the four-station indexing plate 3. Transfer component No. 1 601 is arranged at transfer station No. 1 301 and is used to transfer pipe fittings 8 between transmission component No. 1 201 and the four-station indexing plate 3. Transfer component No. 2 602 is arranged at transfer station No. 2 302 and is used to transfer pipe fittings 8 between transmission component No. 2 202 and the four-station indexing plate 3. Annealing component 4 and processing component 5 are respectively assembled to annealing station 103 and processing station 105. Cooling station 104 is arranged below transmission component No. 2 202.

[0052] The pre-processing station 102 and the post-processing station 106 are both provided with an ultrasonic cleaning box 701 and a drying box 702 arranged along the transmission direction of the pipe 8, and the cooling station 104 is provided with a cooling box 703.

[0053] Steel bent pipes are required in the liquid receivers of household air conditioner compressors to store and transport refrigerant. Traditionally, this process involves using specially annealed carbon steel raw material. After cleaning and drying, the pipes are bent using a pipe bender. The ends of the pipes are then shaped and cleaned again before being sorted and packaged.

[0054] In the traditional pipe bending process, the entire pipe body needs to be annealed to reduce the stress of the steel pipe and improve its plasticity, thereby facilitating subsequent bending. The full annealing treatment method will lose the strength of the steel pipe, making it easy to deform after bending, and the material cost of the steel pipe is relatively high.

[0055] The pipe bending equipment provided in this solution can process ordinary carbon steel pipes and adopts the method of local annealing of the bent part. The strength of the unannealed area is good and it is not easy to deform. It can also effectively reduce the production cost of the pipe bending process.

[0056] When the pipe bending equipment is in operation, the pipe fitting 8 is first loaded onto the No. 1 transmission component 201 at the loading station 101, and the No. 1 transmission component 201 drives the unprocessed pipe fitting 8 to be transported backward, and sequentially passes through the ultrasonic cleaning box 701 and the drying box 702 provided at the pre-processing station 102 for pre-processing of cleaning and drying, and then the No. 1 transfer component 601 transfers the pipe fitting 8 to the No. 1 transfer station 301 provided on the four-station indexing plate 3, and transfers it to the annealing component 4 when the four-station indexing plate 3 is in operation, and then the pipe fitting 8 is transported to the No. 1 transfer station 301 on the four-station indexing plate 3. The annealing component 4 performs local annealing on the bent part of the pipe 8 and then transfers it to the No. 2 transfer station 302. Thereafter, the annealed pipe 8 is transferred to the No. 2 transmission component 202 with the help of the No. 2 transfer component 602, and is driven by the No. 2 transmission group component and enters the cooling box 703 of the cooling station 104 for cooling treatment. After the cooling treatment, the pipe 8 is transferred back to the No. 2 transfer component 602 under the drive of the No. 2 transmission component 202, and is transferred back to the No. 2 transfer station 302 by the No. 2 transfer station 302.

[0057] Under the continued drive of the four-station indexing plate 3, it is transferred to the processing station 105, and the bending and end forming processing of the pipe fitting 8 is completed with the help of the processing component 5 provided here, and then it continues to be driven to transfer station No. 1 301, and the processed pipe fitting 8 is reloaded onto the No. 1 transmission component 201 by the No. 1 transfer station 301. Under the reverse direction transmission of the No. 1 transmission component 201, it passes through the ultrasonic cleaning box 701 and the drying box 702 located in the post-processing station 106, enters the post-processing station 106 to clean and dry the processed pipe fitting 8, and then is transferred to the front side end of the No. 1 transmission component 201, and finally the unloading processing of the pipe fitting 8 is completed at the unloading station 107.

[0058] Example 2

[0059] See also Figure 1-Figure 5 In order to ensure that the No. 1 transmission component 201 and the No. 2 transmission component 202 can effectively clamp the pipe 8 and stably transmit it, and to run the pipe 8 in both forward and reverse directions to meet the stable transmission of the pipe 8 at the pre-processing station 102, the post-processing station 106, and the cooling station 104, the following technical solutions are provided.

[0060] Transmission assembly No. 1 201 and transmission assembly No. 2 202 both include a driving wheel 21, a driven wheel 22, a guide wheel 23, a synchronous belt 24, a clamping mechanism 25, and a limiting rail 26. The axes of the driving wheel 21 and the driven wheel 22 are arranged in the vertical direction. The synchronous belt 24 is wrapped around the outer edges of the driving wheel 21 and the driven wheel 22 and is arranged in a closed shape. The guide wheel 23 maintains contact with the synchronous belt 24 and drives the synchronous belt 24 to present a sinking section 241. The ultrasonic cleaning box 701, the drying box 702, and the cooling box 703 are all arranged at the sinking section 241 of the synchronous belt 24.

[0061] The limiting rail 26 keeps consistent with the undulating path of the synchronous belt 24 , and the clamping mechanism 25 is evenly assembled on the synchronous belt 24 and keeps a matching combination with the limiting rail 26 .

[0062] Both the driving pulley 21 and the driven pulley 22 are large synchronous pulleys capable of driving the timing belt 24 to continuously and stably operate within a closed loop. The driving pulley 21 requires a motor to provide power input. A guide pulley 23 is mounted at a specific position on the timing belt 24 and is used to adjust the height of the timing belt 24, thereby creating a sunken section 241.

[0063] For the first transmission assembly 201, the synchronous belt 24 has four sunken sections 241, two of which are located at the pre-processing station 102 and the post-processing station 106, respectively corresponding to the ultrasonic cleaning box 701 and the drying box 702. For the second transmission assembly 202, the synchronous belt 24 has one sunken section 241, and the cooling box 703 is located at this sunken section 241.

[0064] During the continuous circulation of the synchronous belt 24, two sections with opposite running directions, one moving forward and the other moving backward, are formed, thereby ensuring that the pipe 8 fixed to the clamping mechanism 25 can be transported in the forward direction from the loading station 101 to the forward processing station 102 and in the reverse direction from the post-processing station 106 to the unloading station 107. This also allows the pipe 8 undergoing cooling treatment on the second transmission assembly 202 to be transported from the second transfer station 302 to the cooling box 703 and then returned from the cooling box 703 to the second transfer station 302.

[0065] In order to ensure that the clamping mechanism 25 can effectively clamp the pipe 8 and the limiting rail 26 cooperates to achieve continuous clamping of the clamping mechanism 25, the following technical solution is provided.

[0066] The clamping mechanism 25 includes an assembly bracket 251, a telescopic rod 252, a No. 1 connecting rod 253, a No. 2 connecting rod 254, a clamping claw 255, a support spring 256, and a support wheel 257. The assembly bracket 251 is fixedly installed to the outer wall of the synchronous belt 24, the telescopic rod 252 is slidably installed on the assembly bracket 251, the No. 1 connecting rod 253 is hinged to the assembly bracket 251 and includes multiple groups distributed in a circular array, the No. 2 connecting rod 254 is connected to the bottom end of the telescopic rod 252 and includes multiple groups distributed in a circular array, the clamping claw 255 is hinged to the No. 1 connecting rod 253 and the No. 2 connecting rod 254, the support spring 256 is sleeved on the outer periphery of the telescopic rod 252 and maintains contact with the assembly bracket 251, and the support wheel 257 is rotatably installed to the top of the telescopic rod 252 and maintains contact with the bottom of the limiting track 26.

[0067] The assembly bracket 251 can ensure that the remaining components are assembled on it and realize a fixed connection with the synchronous belt 24. The telescopic rod 252 tends to move upward under the action of the support spring 256 and can ensure that the support wheel 257 thereon always keeps in contact with the limiting track 26. When the telescopic rod 252 is in a high position, it can pull each group of clamps 255 into a retracted state through the No. 2 connecting rod 254, thereby effectively clamping the top of the pipe fitting 8, and the cooperation between the support wheel 257 and the limiting track 26 can ensure that the clamping assembly maintains synchronous operation under the driving action of the synchronous belt 24, thereby realizing stable transmission of the clamped pipe fitting 8.

[0068] Example 3

[0069] See also Figure 5-Figure 7 In order to ensure that the clamping mechanism 25 can realize the loading and unloading operations and transfer operations of the pipe 8 at the loading station 101, the unloading station 107, the No. 1 transfer station 301, and the No. 2 transfer station 302, the following technical solutions are provided.

[0070] Transmission component No. 1 201 and transmission component No. 2 202 both include an unlocking mechanism 27. The front and rear ends of the limiting track 26 of transmission component No. 1 201 and the front side end of the limiting track 26 of transmission component No. 2 202 are both equipped with an unlocking mechanism 27. The unlocking mechanism 27 includes a pressure seat 271, an assembly plate 272, and a telescopic cylinder A273. The assembly plate 272 is fixedly installed on the limiting track 26. The telescopic cylinder A273 is fixedly installed on the assembly plate 272 and arranged in the vertical direction. The pressure seat 271 is slidably installed in the limiting track 26 and is fixedly connected to the movable end of the telescopic cylinder A273.

[0071] When the clamping mechanism 25 moves to the position where the unlocking mechanism 27 is provided to perform loading and unloading operations or transfer operations on the pipe 8, the telescopic cylinder A273 is controlled to drive the pressure seat 271 to move downward, and the pressure seat 271 presses down the support wheel 257 and the telescopic rod 252, thereby driving each group of jaws 255 to open outward and cancel the clamping effect on the top of the pipe 8. At this time, the loading and unloading operations of the pipe 8 can be completed at the loading station 101 or the unloading station 107, or the transfer operation of the pipe 8 can be completed in cooperation with the No. 1 transfer component 601 and the No. 2 transfer component 602.

[0072] In order to ensure that the No. 1 transfer component 601 and the No. 2 transfer component 602 can cooperate with the unlocking component and complete the transfer operation of the pipe 8 between the transmission component and the transfer component, the following technical solution is provided.

[0073] Transfer assembly No. 1 601 and transfer assembly No. 2 602 both include an installation base A61, a rotating seat A62, an assembly frame plate 63, a clamp A64, a telescopic cylinder B65, and a drive motor A66. The rotating seat A62 is rotatably installed on the installation base A61, the telescopic cylinder B65 is fixedly installed on the rotating seat A62 and arranged in the vertical direction, the assembly frame plate 63 is fixedly installed on the movable end of the telescopic cylinder B65, and the periphery of the assembly frame plate 63 is equipped with three groups of clamps A64 distributed in a circular array. The drive motor A66 is fixedly installed in the installation base A61 and maintains a power connection with the rotating seat A62.

[0074] A guide column 631 extending downward is fixedly connected to the assembly frame plate 63. The guide column 631 is slidably connected to the rotating seat A62. The drive motor A66 is powered by the rotating seat A62 through a combination of bevel gears. When the drive motor A66 is running, it can drive the rotating seat A62, the assembly frame plate 63, and the clamp A64 to operate stably, and the telescopic movement of the telescopic cylinder B65 can drive the assembly frame plate 63 and the clamp A64 thereon to adjust their height.

[0075] For the No. 1 transfer component 601, the three sets of clamps A64 thereon can respectively face the two sets of unlocking components at the rear end of the No. 1 transmission component 201 and the No. 1 transfer station 301. The clamps A64 are designed as a U-shaped structure to avoid spatial movement interference with the bent pipe 8. The height posture is adjusted by the telescopic cylinder B65, and the No. 1 transmission component 201 and the four-station indexing plate 3 can be raised and lowered to complete the clamping and transfer operations of the pipe 8. When the No. 1 transfer component 601 is in operation, the pipe 8 processed at the pre-processing station 102 can be transferred to the No. 1 transfer station 301 at the same time, and the pipe 8 processed at the No. 1 transfer station 301 can be transported to the upstream side of the post-processing station 106.

[0076] For the No. 2 transfer component 602, the three groups of clamps A64 thereon can respectively correspond to the two groups of unlocking components at the front end of the No. 2 transmission component 202 and the No. 2 transfer station 302, thereby simultaneously completing the transfer of the pipe fittings 8 processed at the cooling station 104 to the No. 1 transfer station 301, and transferring the pipe fittings 8 that have completed annealing treatment at the No. 1 transfer station 301 to the No. 2 transmission component 202.

[0077] Example 4

[0078] See also Figure 1 、 Figure 6 、 Figure 8 In order to ensure that the four-station indexing plate 3 can operate stably and realize the stable installation of the annealing component 4 and the processing component 5 thereon, and at the same time realize the coordinated operation with the No. 1 transfer component 601 and the No. 2 transfer component 602, the following technical solutions are provided.

[0079] The four-station indexing plate 3 includes a mounting base B31, a rotating base B32, a rotating disk 33, a fixed disk 34, a clamp B35, and a drive motor B36. The rotating base B32 is rotatably mounted on the mounting base B31, the rotating disk 33 and the rotating base B32 are coaxially fixedly connected, the fixed disk 34 is fixedly mounted on the mounting base B31 and is arranged below the rotating disk 33, and the periphery of the rotating disk 33 is equipped with four groups of clamps B35 distributed in a circular array. The drive motor B36 is fixedly mounted on the mounting base B31 and maintains a power connection with the rotating base B32. The annealing component 4 and the processing component 5 are both assembled on the fixed disk 34.

[0080] The rotating disk 33 is arranged on the assembly frame plate 63 of the No. 1 transfer component 601 and the No. 2 transfer component 602, and can realize the relative arrangement of the clamp B35 and the clamp A64 in the same vertical axis, thereby ensuring that the clamp A64 and the clamp B35 cooperate to realize the effective transfer of the pipe 8.

[0081] The driving motor B36 is connected to the rotating seat B32 through a combination of bevel gears to achieve power connection, thereby driving the rotating seat B32 and the rotating disk 33 to operate stably, so that the pipe fitting 8 clamped on the clamp B35 can pass through the No. 1 transfer station 301, annealing station 103, processing station 105, and No. 2 transfer station 302 in sequence, and complete the annealing and processing operations of the pipe fitting 8 in the annealing station 103 and the processing station 105 in the cooperation of annealing assembly 4 and processing assembly 5.

[0082] Example 5

[0083] See also Figure 6 、 Figures 8-11 In order to ensure that the annealing assembly 4 can be stably assembled on the fixed plate 34 and realize local heating annealing of the pipe 8, the following technical solution is provided.

[0084] The annealing assembly 4 includes an assembly sleeve 41, a telescopic cylinder C42, and a high-frequency induction heating furnace 43. The assembly sleeve 41 is fixedly installed to the bottom of the fixed plate 34, the telescopic cylinder C42 is fixedly installed to the assembly sleeve, and the high-frequency induction heating furnace 43 is fixedly installed to the movable end of the telescopic cylinder C42.

[0085] The installation of the assembly sleeve 41 ensures stable installation of the telescopic cylinder C42 and prevents spatial motion interference between the high-frequency induction heating furnace 43 and the fixed plate 34 during the descent process. As the rotating plate 33 drives the pipe 8 clamped thereon, the telescopic cylinder C42 drives the high-frequency induction heating furnace 43 downward, avoiding spatial motion interference with the pipe 8.

[0086] During the annealing treatment, the telescopic cylinder C42 is controlled to operate and drive the high-frequency induction heating furnace 43 to rise so that the part of the bottom end of the pipe 8 that needs to be bent extends into it. The high-frequency induction heating furnace 43 induces eddy currents inside the metal to achieve efficient heating of the pipe 8.

[0087] In order to ensure that the processing assembly 5 can be stably installed on the fixed plate 34 and realize effective bending of the pipe 8, the following technical solution is provided.

[0088] The processing assembly 5 includes a telescopic cylinder D51, a pressure wheel 52 and two sets of assembly bases 53 fixedly mounted on the fixed plate 34. The two sets of assembly bases 53 are fixedly mounted with a horizontally arranged telescopic cylinder D51. The movable end of the telescopic cylinder D51 is rotatably mounted with a pressure wheel 52. The pipe fitting 8 at the processing station 105 is arranged between the two sets of pressure wheels 52, and the two sets of pressure wheels 52 are arranged at different heights.

[0089] When both sets of telescopic cylinders D51 are in a retracted position, they can move out of the way to avoid spatial motion interference between the rotating disk 33 and the processing assembly 5 when the pipe 8 is driven to operate. When the pipe 8 is bent, the two sets of telescopic cylinders D51 are controlled to drive the pressure wheels 52 to extend and press against both sides of the pipe 8. Then, the lower telescopic cylinder D51 is controlled to drive the corresponding pressure wheels 52 to continue to extend, so as to achieve efficient bending of the pipe 8.

[0090] On the basis of the above technical solution, in order to ensure that the processing assembly 5 can perform forming processing on the port position of the pipe 8, the following technical solution is provided.

[0091] The processing component 5 also includes a transverse port forming mechanism 5401 and a longitudinal port forming mechanism 5402. The transverse port forming mechanism 5401 and the longitudinal port forming mechanism 5402 both include a mounting bracket 541, a telescopic cylinder E542, a drive motor C543, and a drill bit 544. The mounting brackets 541 in the transverse port forming mechanism 5401 and the longitudinal port forming mechanism 5402 are respectively slidably installed on two sets of assembly bases 53 and slide in the horizontal and vertical directions respectively. The telescopic cylinder E542 is fixedly installed on the assembly base 53 and is power-connected to the mounting bracket 541. The drive motor C543 is fixedly installed on the mounting bracket 541. The drill bit 544 is rotatably installed on the mounting bracket 541 and is power-connected to the drive motor C543.

[0092] Telescopic cylinder E542 drives mounting bracket 541 and the other components mounted thereon to synchronize their telescopic motion, thereby precisely aligning drill bit 544 with the port of pipe fitting 8. Drive motor C543 is connected to drill bit 544 via a bevel gear assembly, driving stable operation. Depending on the port processing technology, drill bit 544 can be a reaming drill bit 544, a tapping drill bit 544, or other similar tool to achieve the desired shaping of the port of pipe fitting 8, thereby meeting its assembly requirements on the reservoir.
