Description

Technical Field

[0001] This invention relates to the field of manifold technology, and in particular to a method for manufacturing a condenser manifold. Background Technology

[0002] Automotive condensers typically have baffles inside the manifold to divide the interior into different flow channels, allowing the medium to flow along a predetermined path. Existing manifold baffles usually have lugs on their circumference, and mounting holes corresponding to these lugs are machined radially into the manifold wall. During assembly, the baffle is inserted axially into the manifold, allowing the lugs on the baffle to enter the mounting holes, thus positioning and supporting the baffle. References can be made to an externally clamping condenser manifold baffle disclosed in Publication No. CN202692552U, and a parallel flow condenser baffle groove and baffle mounting structure disclosed in Publication No. CN205373493U.

[0003] However, the above structure has certain shortcomings in actual use. The baffle mainly relies on the local part of the lug that contacts the manifold for support, and the effective support area between the baffle and the manifold is relatively small. When the medium inside the manifold flows and impacts the baffle, the load on the baffle tends to concentrate on the lug, causing uneven stress on the baffle. Over long-term use, the baffle may deform, thus affecting its separation effect on the flow channels inside the manifold. Summary of the Invention

[0004] The purpose of this invention is to solve one of the problems pointed out in the background art, and to propose a method for manufacturing a condenser manifold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A method for manufacturing a condenser manifold includes the following steps:

[0007] S1. Prepare a bowl-shaped septum, the septum comprising an integral septum body and an annular portion, wherein the periphery of the septum is interference-fitted with the inner peripheral wall of the manifold.

[0008] S2. Several first annular grooves are opened on the inner circumferential wall of the part of the manifold where the baffle needs to be installed;

[0009] S3. Insert the partition into the inside of the manifold along one end. When it reaches the corresponding first annular groove position, press at least a portion of the ring body into the corresponding first annular groove using a riveting device.

[0010] The present invention proposes a method for manufacturing a condenser manifold, which has the following advantages: This method eliminates the need for radial mounting holes on the outer circumference of the manifold, reducing damage to the manifold structure and helping to maintain its structural strength and appearance integrity; the partition plate, through an interference fit between its circumference and the inner circumferential wall of the manifold, improves the sealing performance between the partition plate and the manifold, reducing media cross-flow; simultaneously, by pressing at least a portion of the ring body into the first annular groove and setting multiple evenly distributed riveting points along the circumference, the partition plate achieves multi-point circumferential positioning, improving stress distribution and reducing the possibility of deformation after the partition plate is impacted by the media, thereby improving the stability and reliability of the partition plate installation.

[0016] Reference Figures 1-3 A method for manufacturing a condenser manifold includes the following steps:

[0017] s1. Prepare a bowl-shaped septum 4. The septum 4 includes an integral septum body 10 and an annular part 11. The periphery of the septum 4 is press-fitted with the inner peripheral wall of the manifold 1. The press-fit allows the septum 4 to seal and separate the upper and lower spaces when it is located inside the manifold 1.

[0018] s2. Several first annular grooves 8 are opened on the inner circumferential wall of the part where the baffle 4 needs to be installed in the manifold 1;

[0019] s3. Insert the partition 4 into the inside of the manifold 1 along one end of the manifold 1. When it reaches the corresponding first annular groove 8, press at least a portion of the ring body 11 into the corresponding first annular groove 8 using a riveting device.

[0020] When manufacturing and assembling the partition using this method, on the one hand, there is no need to open radial holes for installing the partition 4 on the outer periphery of the manifold 1, which reduces damage to the structure of the manifold 1 and helps maintain the structural strength and appearance integrity of the manifold 1; on the other hand, after the partition 4 is inserted into the manifold 1, the interference fit between the periphery of the partition 4 and the inner wall of the manifold 1 allows the partition 4 to seal and separate the upper and lower spaces inside the manifold 1, preventing the medium from flowing between the two sides of the partition 4. After the partition 4 reaches the position of the first annular groove 8, at least a portion of the ring body 11 is pressed into the first annular groove 8 by a riveting device, thereby further positioning the partition 4; the riveting points can be spaced apart and evenly arranged along the circumference of the partition 4, so that each part of the periphery of the partition 4 can be subjected to a corresponding positioning effect, which helps to disperse the impact force of the medium on the partition 4 and reduces the possibility of deformation of the partition 4 due to local stress.

[0021] As one implementation method, the partition 4 is formed by casting.

[0022] In one implementation, the spacer 4 is formed by stamping, using a round aluminum or copper sheet. A groove-shaped die, in conjunction with a stamping head, stamps the round metal sheet into shape. Figure 1 The structure shown.

[0023] The thickness of the ring portion 11 is less than the thickness of the spacer body 10. For example, when stamping is used, the portion of the disc corresponding to the ring portion 11 is thinned by the stamping and stretching action, making it easier to rivet into the first ring groove 8.

[0024] As one implementation method, refer to Figures 1-3 The riveting device includes a cylinder 2 and a rod 3. The rod 3 can move within the cylinder 2 along its axial direction. The cylinder 2 and the manifold 1 can move relative to each other along the axial direction of the manifold 1. Several riveting heads 5 are slidably installed around one end of the cylinder 2 along its radial direction. The rod 3 can cause the riveting heads 5 to spread radially around the cylinder 2, so that the movement of the riveting heads 5 can press part of the ring body 11 into the first ring groove 8.

[0025] In use, the insert 2 is inserted into the manifold 1 and the riveting head 5 is aligned with the ring body 11. The insert rod 3 is driven to move axially along the insert 2, and the riveting head 5 moves radially outward along the insert 2 and squeezes the ring body 11, thereby pressing part of the ring body 11 into the first annular groove 8. Since multiple riveting heads 5 are spaced apart circumferentially along the insert 2, multiple positions of the ring body 11 can be riveted simultaneously, so that multiple positions of the spacer 4 are matched with the first annular groove 8. While realizing the positioning of the spacer 4, it is beneficial to make the force on the spacer 4 more uniform in the circumferential direction.

[0026] The end of the rivet head 5 near the central axis of the insert cylinder 2 has a wedge-shaped surface 12, and the end of the insert rod 3 has a tapered surface 7. When the insert rod 3 is gradually inserted into the insert cylinder 2, the rivet head 5 gradually expands to the surrounding area through the cooperation of the wedge-shaped surface, forming a compression on the ring body 11, causing the ring body 11 to deform and be pressed into the first ring groove 8.

[0027] A fixing component 13 is installed at one end of the insert 2, and the spacer 4 is detachably installed on the fixing component 13. The spacer 4 is fixed to the end of the insert 2 by the fixing component 13, and then the manifold 1 or the insert 2 is moved to insert the spacer 4 into the corresponding position of the manifold 1.

[0028] The fixing component 13 is a suction cup. Using a suction cup is simple and convenient. It can be used to hold the inner bottom plane of the diaphragm body 10, and then the diaphragm can be inserted into the manifold. Alternatively, the diaphragm can be fixed by a negative pressure suction component.

[0029] In S2, the manifold 1 has a second annular groove 9 at an adjacent position to each first annular groove 8. A detection head 6 is installed on the outer wall of the insert 2. The detection head 6 includes a support base 16 fixed to the outer wall of the insert 2. An elastic head 14 is slidably connected to the support base 16 along the radial direction of the insert 2. A thrust spring 15 is connected between the elastic head 14 and the support base 16. A second electrode 18 is fixed to the support base 16, and a first electrode 17 is fixed to the elastic head 14. The first electrode 17 and the second electrode 18 are electrically connected to the controller or indicator light to form a detection circuit. When the elastic head 14 moves to the second annular groove 9, the first electrode 17 and the second electrode 18 separate. When the elastic head 14 is in the manifold 1 and located outside the second annular groove 9, the first electrode 17 and the second electrode 18 abut against each other.

[0030] The spacer 4 is fixed to the end of the insert 2 using a suction cup, keeping the spacer 4 and the insert 2 relatively fixed. Since the distance between the first annular groove 8 and the second annular groove 9 is a fixed value, the distance between the riveting head 5 and the detection head 6 corresponds to the distance between the first annular groove 8 and the second annular groove 9. Therefore, when the insert 2 moves axially along the manifold 1, when the detection head 6 moves to the position of the second annular groove 9, the elastic head 14 moves towards the inner circumferential wall of the manifold 1 under the action of the thrust spring 15, causing the first electrode 17 and the second electrode 18 to separate, and the detection circuit changes. At this time, it indicates that the riveting head 5 and the spacer 4 have moved synchronously to the corresponding position of the first annular groove 8, and the insert rod 3 can be driven to move, causing the riveting head 5 to move towards the inner circumferential wall of the manifold 1 and squeeze the ring body 11, so that part of the ring body 11 is pressed into the first annular groove 8. Through the above settings, the riveting position of the spacer 4 can be determined by the fixed positional relationship between the first annular groove 8 and the second annular groove 9, which is beneficial to improving the accuracy of the installation position of the spacer 4.

[0031] The insert 2 is fixed to the frame, the manifold 1 is detachably mounted on the first telescopic mechanism, and the insert rod 3 is detachably mounted on the second telescopic mechanism. Both the first and second telescopic mechanisms are connected to a controller, which can control the movement distance of the first and second telescopic mechanisms. The telescopic mechanism can be a hydraulic cylinder or a ball screw mechanism.

[0032] During actual assembly, the inner circumferential wall of the manifold 1 is provided with multiple sets of first annular grooves 8 and second annular grooves 9 along its axial direction. One end of the manifold 1 is defined as the head end and the other end as the tail end. The partitions 4 are assembled sequentially from the head end to the tail end. Taking the assembly of three partitions 4 as an example, when assembling the partitions 4 corresponding to the first set of first annular grooves 8, the manifold 1 is first installed on the first telescopic mechanism, and the partitions 4 are installed on the fixing component 13 of the insert 2. By controlling the first telescopic mechanism, the manifold 1 is driven to move axially, so that the manifold 1 is sleeved on the outside of the partitions 4 and moves to the preset assembly position. When the movement distance of the first telescopic mechanism reaches the preset value, it is used as the first judgment criterion for the manifold 1 to reach the assembly position.

[0033] During the movement of the manifold 1, multiple sets of first annular grooves 8 and second annular grooves 9 are sequentially arranged along the axial direction on the manifold 1, and the positions of the first annular grooves 8 and second annular grooves 9 are set according to a preset spacing. When the detection head 6 moves relative to the manifold 1 with the insert 2, it will pass through multiple second annular grooves 9 in sequence. Taking the assembly of the first set of partitions 4 as an example, the detection head 6 generates arrival position signals when it passes through the first two sets of second annular grooves 9. When the detection head 6 arrives at the second annular groove 9 for the third time, it indicates that the riveting head 5 and the partition 4 have moved to the corresponding position of the first set of first annular grooves 8. At this time, the third arrival position signal is used as the second judgment criterion.

[0034] The controller simultaneously acquires the first and second judgment criteria. When the movement distance of the first telescopic mechanism reaches a preset value, and the detection head 6 generates an arrival position signal corresponding to the currently assembled partition 4, it is determined that the manifold 1, partition 4, and riveting head 5 have all reached the preset assembly position. Only then does the controller control the second telescopic mechanism to move, causing the insertion rod 3 to push the riveting head 5 outward, pressing at least a portion of the ring body 11 into the first ring groove 8, thus completing the installation of the partition 4. After riveting is completed, the first and second telescopic mechanisms are reset respectively, and the assembly of the next partition 4 is then performed.

[0035] By comparing the movement distance of the first telescopic mechanism with the arrival position signal of the detection head 6, and using the simultaneous satisfaction of both judgment criteria as the riveting condition, the relative assembly position of the manifold 1 and the partition 4 can be double-confirmed, avoiding positional deviation caused by riveting based on only a single position parameter, thereby improving the correspondence accuracy between the partition 4 and the first annular groove 8, and realizing the precise positioning and fixing of the partition 4.

[0036] The above are merely typical specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any technical solutions, concepts, and designs obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solutions and inventive concepts of this application within the scope of the technology disclosed in this application should be covered within the scope of protection of this application.
