Description

Technical Field

[0001] This invention relates to pipe fitting production equipment, specifically to a flexible integrated crimping mold. Background Technology

[0002] The turbocharger inlet pipe is a dedicated pipeline connecting the engine's main oil passage to the oil inlet of the turbocharger's intermediate body. The main functions of the turbocharger inlet pipe are as follows: Lubricated bearings: High-pressure engine oil from the main oil passage is introduced into the fully floating bearing in the turbocharger intermediate body to establish an oil film between the high-speed rotating journal and the bearing, reducing friction and wear.

[0003] Cooling and heat dissipation: The flowing oil carries away the heat generated by the rotor shaft and bearings due to high speed (up to tens of thousands of revolutions per minute) and high ambient temperature, preventing the oil from coking or the bearings from seizing.

[0004] Cleaning the seal: The continuously flowing oil flushes away impurities in the bearing clearances and helps maintain pressure balance at the shaft seal, preventing oil leaks. The turbocharger inlet pipe typically consists of a rigid metal tube and a flexible hose. The hose is a flexible corrugated / steel-braided rubber hose. For example, the steel-braided rubber hose uses a double structure with high-temperature resistant fluororubber and a metal braided layer. The metal tube ensures a secure connection, while the hose section absorbs vibration and displacement between the engine and the turbocharger, preventing fatigue fracture. There are two traditional methods for fixing the metal tube and hose: The first type: Socket connection with clamp fastening: The hose is directly inserted into the connector of the extended metal pipe (or a rigid pipe is inserted into the hose), and radially tightened using screw-type clamps or spring clamps. This connection structure relies on friction to adhere to the sealing surface to prevent leakage, and is suitable for low-pressure oil inlet or space-constrained scenarios, thus limiting its application range.

[0005] The second type: dedicated transition joint connection: the metal pipe and hose are connected to the same metal transition joint via threads / flanges. Oil-resistant O-rings / paper gaskets / rubber gaskets are installed inside or on the end face of the joint. A seal is achieved by tightening bolts to generate preload. This type is commonly used in high-temperature and high-pressure applications and can absorb vibration and thermal expansion / contraction. This connection structure requires more parts, resulting in higher costs and a more time-consuming assembly process with lower efficiency. Summary of the Invention

[0006] This invention provides a flexible, one-piece pressing mold that can improve production efficiency.

[0007] A flexible integrated crimping mold includes: an upper mounting base; A first elastic clamping device is connected to the upper mounting base; Lower mounting base; A second elastic clamping device is connected to the lower mounting base, and the first elastic clamping device and / or the second elastic clamping device are provided with a mating groove. The pipe fitting positioning assembly is fixed to the second elastic clamping device, and moves as the second elastic clamping device moves.

[0008] This invention employs a press-fit method to fix the clamping tube to the metal tube and hose. During press-fitting, simply place the pre-assembled inlet pipe of the booster into the engagement groove on the second elastic clamping device, start the press, and the press drives the first elastic clamping device to move towards the second elastic clamping device. As the first and second elastic clamping devices engage, the clamping tube retracts, thereby fixing the clamping tube to the metal tube and hose. This invention not only simplifies the press-fitting operation but also allows for rapid pressing, thus improving production efficiency.

[0009] The turbocharger inlet pipe obtained by press fitting according to the present invention has the following advantages: Strong vibration and breakage resistance: After the clamp is fixed to the metal pipe and hose by press fitting, the entire turbocharger oil inlet pipe can effectively absorb the relative displacement and high-frequency vibration between the engine and the turbine, avoiding cracks or breaks caused by fatigue due to rigid threaded connections.

[0010] High sealing reliability: Relying on a precision crimping process to fix the crimped tube to the metal tube and hose, it not only plays a sealing role, but also does not rely on manual tightening torque, eliminating the risk of leakage caused by stripped threads, failure of PTFE tape, or uneven tightening.

[0011] Resistant to pulsating pressure shocks: After being press-fitted to the metal pipes and hoses, the overall structure is robust and adaptable to pressure pulsations generated by oil pumping, reducing the likelihood of loose connections or fretting wear. Attached Figure Description

Detailed Implementation

[0021] like Figures 1 to 8 As shown, the present invention will be described using the turbocharger inlet pipe as an example. The turbocharger inlet pipe includes a metal pipe 1 and a flexible hose 2. The turbocharger inlet pipe also includes a clamping pipe 3. One end of the metal pipe 1 is provided with a bulge 4. The flexible integrated clamping mold of the present invention includes an upper mounting base 10, a first elastic clamping device A, a lower mounting base 11, a second elastic clamping device B, a first clamping block C, a second clamping block D, and a pipe positioning assembly. The flexible integrated clamping mold of the present invention applies a clamping force to the clamping pipe 3, causing the clamping pipe 3 to contract and fixing the metal pipe 1 and the flexible hose 2 with the bulge 4 into one piece. The following is a detailed description of each part and the relationship between them.

[0022] The first elastic clamping device A is connected to the upper mounting base 10. The upper mounting base 10 is fixed with a connector 10b, which is connected to a stamping machine (not shown in the figure). The stamping machine drives the upper mounting base 10 to move up and down.

[0023] The second elastic clamping device B is connected to the lower mounting base 11. The second elastic clamping device B is located directly below the first elastic clamping device A. The first elastic clamping device A and / or the second elastic clamping device B are provided with mating grooves E that respectively cooperate with the metal tube 1, the flexible hose 2, and the clamping tube 3.

[0024] In this embodiment, there are two first elastic clamping devices A and two second elastic clamping devices B. A first guide key 10a is fixed on the upper mounting base 10. Each first elastic clamping device A is provided with a first keyway and a first mounting groove 12c. The first keyway on each first elastic clamping device A cooperates with the first guide key 10a. The first pressing block C cooperates with the first mounting groove 12c. The first pressing block C is fixed to the upper mounting base 10. The first pressing block C is L-shaped. The first pressing block C is preferably fixed to the upper mounting base 10 by screws. The first elastic clamping device A is pressed onto the upper mounting base 10 by the first pressing block C.

[0025] The lower mounting base 11 is fixed with a second guide key 11a. Each second elastic clamping device B is provided with a second keyway and a second mounting groove 12d. The second keyway on each second elastic clamping device B cooperates with the second guide key 11a. The second clamping block D cooperates with the second mounting groove 12d. The second clamping block D is fixed to the lower mounting base 11. The second clamping block D is L-shaped. The second clamping block D is preferably fixed to the lower mounting base 11 by screws. The second elastic clamping device B is pressed onto the lower mounting base 11 by the second clamping block D.

[0026] When the lengths of the hoses 2 are different, the first clamping block C is loosened, allowing the first elastic clamping device A to slide along the first guide key 10a, thus changing the distance between the two first elastic clamping devices A. Similarly, the second clamping block D is loosened, allowing the second elastic clamping device B to slide along the second guide key 11a, thus changing the distance between the two second elastic clamping devices B. When the distance between the two first elastic clamping devices A meets the requirements, the first clamping block C is tightened, pressing the first elastic clamping device A onto the upper mounting base 10. When the distance between the two second elastic clamping devices B meets the requirements, the second clamping block D is tightened, pressing the second elastic clamping device B onto the lower mounting base 11, thereby adapting to the pressing requirements of different hoses 2.

[0027] Both the first elastic clamping device A and the second elastic clamping device B include a first mold base 12, an elastic clamping assembly, a first guide component 13, and a first connecting shaft 14. The lower end of the first mold base 12 is provided with a first groove 12a, and the elastic clamping assembly cooperates with the first groove 12a. The first guide component 13 is fixed to the first mold base 12, and the first guide component 13 is provided with a first guide hole 13a. The first connecting shaft 14 passes through the elastic clamping assembly, and the first connecting shaft 14 is clearance-fitted with the first guide hole 13a.

[0028] For example, since the elastic clamping component in the first elastic clamping device A is suspended above the second elastic clamping device B, and since the first connecting shaft 14 passes through the elastic clamping component in the first elastic clamping device A, and the first connecting shaft 14 is engaged with the first guide hole 13a, the first connecting shaft 14 is supported by the first guide component 13, thereby supporting the elastic clamping component in the first elastic clamping device A and preventing the elastic clamping component in the first elastic clamping device A from falling under the action of gravity.

[0029] The elastic clamping assembly includes a first spring 15, a first support, a first stamping block 16, and a second spring 17. One end of the first spring 15 is located in the first groove 12a and abuts against the first mold base 12. In this embodiment, a first mounting hole 12g is provided on the first mold base 12. One end of the first spring 15 is located in the first mounting hole 12g and abuts against the bottom of the hole. The first mounting hole 12g binds the first spring 15, and the other end of the first spring 15 abuts against the first support. When not in operation, the tension of the first spring 15 causes the first support to move. For example, in the first elastic clamping device A, the elastic force of the first spring 15 causes the first support in the first elastic clamping device A to move downward, and in the second elastic clamping device B, the elastic force of the first spring 15 causes the first support in the second elastic clamping device B to move upward.

[0030] The first connecting shaft 14 passes through the first support, the first support is provided with a first mounting hole, there are multiple first stamping blocks 16, and each first stamping block 16 is slidably engaged with a first mounting hole on the first support, one end of each first stamping block 16 is located on the first circumference, and the other end of each first stamping block 16 is located on the second circumference.

[0031] The second spring 17 is located in the first mounting hole on the first support. One end of the second spring 17 engages with the other end of the first stamping block 16, and the other end of the second spring 17 engages with the first mounting hole. During operation, the first stamping block 16 exerts a force on the clamping tube 3, causing the clamping tube 3 to contract and thus tightening the metal tube 1 and the flexible hose 2. The second spring 17 provides support for the first stamping block 16. In the non-operating state, the second spring 17 returns the first stamping block 16 to its original position.

[0032] The first support can be a cast integral structure with a second mounting hole at the non-stamped end of the first stamping block 16. One end of the second spring 17 mates with the second mounting hole on the first stamping block 16, and the other end mates with the first mounting hole. While this structure can achieve the function of press fitting, it has the following drawbacks: First, this structure requires the second spring 17 to be connected to the first support, and since the second spring 17 is located in the first mounting hole on the first support, connecting the first spring 17 to the first support is difficult. Second, because the walls of the first stamping block 16 and the first mounting hole are subject to wear, both are consumable parts. When the wear of both causes the press fitting accuracy to fail to meet the requirements, the first stamping block 16 and the first support need to be replaced. Since the first support is an integral part, it needs to be replaced as a whole, resulting in high costs for replacing the first support.

[0033] Based on the above factors, the first support in this embodiment adopts a split structure. The first support includes a first slide rail 18 and a first spring seat 19. The first slide rail 18 cooperates with the first groove 12a, and the other end of the first spring 15 abuts against the bottom of the first slide rail 18. The first spring seat 19 and the first slide rail 18 are arranged side by side and fixed to the first slide rail 18. The first spring seat 19 cooperates with the first groove 12a. Multiple first slide rails 18a are arranged at intervals on the side wall of the first slide rail 18 facing the first spring seat 19. Multiple first assembly slots 19a are provided on the side wall of the first spring seat 19 facing the first slide rail 18. Each first assembly slot 19a corresponds to one first slide rail 18a and forms the first assembly hole. A first stop bar 20 is fixed on the first stamping block 16. The first stamping block 16 slides in conjunction with the first sliding groove 18a. The second spring 17 is located in the first assembly groove 19a. The first stop bar 20 extends into the first assembly groove 19a and abuts against one end of the second spring 17. The other end of the second spring 17 abuts against the groove wall 19b of the first assembly groove 19a.

[0034] The advantage of the split structure adopted for the first support in this embodiment is that, firstly, since the first groove 12a is located on the side wall of the first slide rail 18 and the first assembly groove 19a is located on the side wall of the first spring seat 19, both the first groove 12a and the first assembly groove 19a are exposed before assembly. This makes machining the first groove 12a and the first assembly groove 19a easier (e.g., grinding) and also facilitates improving their accuracy. Furthermore, since the first stamping block 16 only slides with the first slide rail 18a, wear only occurs between the first stamping block 16 and the first slide rail 18 during operation. When the first stamping block 16 and the first slide rail 18 wear to the point that the pressing accuracy cannot meet the requirements, only the first stamping block 16 and the first slide rail 18 need to be replaced; the first spring seat 19 does not need to be replaced, thus saving the cost of replacing parts. Furthermore, this structure constrains both ends of the second spring 17 through the first stop 20 and the groove wall 19b. This structure not only supports the first stop 20 and the first stamping block 16 through the second spring 17, preventing the first stamping block 16 from sliding out of the first assembly hole under gravity, but also allows for easy installation by fitting the first stamping block 16 into the first slide groove 18a, placing the second spring 17 in the first assembly groove 19a, and then closing the first slide groove frame 18 and the first spring seat 19. The first stop 20 and the groove wall 19b then constrain both ends of the second spring 17, eliminating the need to fix the second spring 17 to the first slide groove frame 18 and / or the first spring seat 19. Therefore, installation is very convenient.

[0035] Because wear occurs between the first stamping block 16 and the first support due to relative movement, in order to reduce wear, lubricating oil is injected into the first mounting hole on the first support. When the first stamping block 16 is working, the wear between the two can be reduced under the lubrication of the lubricating oil. Based on this, the elastic clamping assembly in this embodiment also includes a first pad 21 and a second pad 22, both located within the first groove 12a and fixed to the first mold base 12. There are multiple first pads 21 and second pads 22, with a first pad 21 disposed between two adjacent second pads 22. The first mold base 12 is provided with an oil injection hole 12b. The end of the first pad 21 facing the first mold base 12 is provided with a first oil groove 21a, which cooperates with the oil injection hole 12b. The thickness of the second pad 22 is greater than the thickness of the first pad 21. A second oil groove 21b is formed between the other ends of the second pad 22 and the first pad 21 to distribute lubricating oil to the elastic clamping assembly. The first pad 21 is also provided with a through hole 21c that passes through the first oil groove 21a and the second oil groove 21b.

[0036] When the lubricating oil enters the oil injection hole 12b, it flows into the first oil groove 21a and then into the second oil groove 21b through the through hole 21c. Since the second oil groove 21b is matched with the first assembly hole, that is, the second oil groove 21b is in the first slide groove 18a and the first assembly groove 19a respectively, the lubricating oil flows into the first slide groove 18a and the first assembly groove 19a, thereby lubricating the first stamping block 16 that moves along the first slide groove 18a.

[0037] The first mold base 12 is provided with a second groove 12e, and the elastic clamping assembly is provided with a third groove 12f. In this embodiment, the first slide rail 18 and the first spring seat 19 are both provided with the third groove 12f. The third groove 12f and the second groove 12e are connected to form a T-shaped groove. A part of the first guide member 13 is located in the second groove 12e, and another part of the first guide member 13 is located in the third groove 12f and is slidably engaged with the third groove 12f. The thickness of the first guide member 13 is less than or equal to the depth of the second groove 12e and the third groove 12f, so the first guide member 13 will not protrude beyond the outer wall of the first mold base 12 and the elastic clamping assembly.

[0038] The elastic clamping assembly also includes guide plates 23. Guide plates 23 are arranged on opposite sides of the first groove 12a on each first mold base 12. The guide plates 23 are fixed to the first mold base 12. The elastic clamping assembly is slidably engaged with the guide plates 23. The first slide rail frame 18 and the first spring seat 19 are located between the two guide plates 23. When the first slide rail frame 18 and the first spring seat 19 are raised or lowered, the two guide plates 23 guide the first slide rail frame 18 and the first spring seat 19, thereby ensuring the raising and lowering accuracy of the first slide rail frame 18 and the first spring seat 19. In addition, the first guide component 13 does not protrude beyond the outer wall of the first mold base 12 and the elastic clamping assembly. In this way, the guide plate 23 and the elastic clamping assembly can directly engage through surface-to-surface contact, without the need to set slide rails on the guide plate 23 or slide grooves on the elastic clamping assembly. Therefore, this structure simplifies the structure and reduces manufacturing costs.

[0039] The connecting groove E is provided on the elastic clamping assembly. The first elastic clamping device A and / or the second elastic clamping device B also include a positioning seat 24a with a groove for positioning the clamping tube 3. The positioning seat 24a is fixed to the elastic clamping assembly, and the hose 2 is engaged with the groove on the positioning seat 24a. The first slide groove 18a and the first assembly groove 19a are connected to the connecting groove E, so that the end of the first stamping block 16 extends into the connecting groove E when it is not working. Since the turbocharger oil inlet pipe is first connected to the connecting groove E on the second elastic clamping device B, this allows the first stamping block 16 to be connected to the clamping tube 3, and the positioning seat 24a positions one end of the clamping tube 3 to ensure that the installation position of the clamping tube 3 is located at the junction of the metal tube 1 and the hose 2, and after clamping, the clamping tube 3 can form abutment with the bulge 4, while the hose 2 and the metal tube 1 are connected to other parts of the connecting groove E. The other parts of the connecting groove E include the first connecting groove 18b provided on the first slide frame 18 and the second connecting groove 19c provided on the first spring seat 19.

[0040] The pipe positioning assembly positions the metal pipe 1. The pipe positioning assembly is fixed to the second elastic clamping device B and moves with the movement of the second elastic clamping device B. The pipe positioning assembly includes a first support 24, a first positioning seat 25, a second support 26, and a second positioning seat 27. The first support 24 is located on one side of the second elastic clamping device B and is fixed to it. The first positioning seat 25 is fixed to the first support 24 and has a fourth groove 25a that mates with the metal pipe 1. The second support 26 is located on the other side of the second elastic clamping device B and is fixed to it. The second positioning seat 27 is fixed to the second support 26 and has a fifth groove 27a that mates with the metal pipe 1. The pipe positioning assembly supports and restrains the metal pipe 1, preventing it from rotating or shifting during operation, thus ensuring the position of the metal pipe 1 during the pressing process, and consequently ensuring the pressing accuracy of the clamping device 3, the hose 2, and the metal pipe 1.

[0041] The pressing process of this invention is as follows: S1, insert the end of the metal tube 1 with the bulge 4 into the hose 2, and put the buckle 3 on the joint between the metal tube 1 and the hose 2.

[0042] S2, the metal tube 1 is combined with the pipe positioning assembly, and the metal tube 1, hose 2, and buckle 3 are fitted into the second engagement groove, so that the buckle 3 is positioned by the positioning seat 24a. Specifically, there are two buckles 3, each of which engages with one end of the first punch block 16 on a second elastic buckling device B. There are two metal tubes 1. The first metal tube 1 engages with the fourth groove 25a and also engages with the second engagement groove 19c on the first spring seat 19 in the first second elastic buckling device B. The two ends of the hose 2 engage with the first engagement groove 18b on the first slide frame 18 in the two second elastic buckling devices B, respectively. The second metal tube 1 engages with the fifth groove 27a and also engages with the second engagement groove 19c on the first spring seat 19 in the second second elastic buckling device B.

[0043] S3, the first elastic clamping device A feeds towards the second elastic clamping device B. After the first elastic clamping device A and the second elastic clamping device B are combined, they exert a squeezing force on the clamping tube 3, causing the clamping tube 3 to contract. The contracted clamping tube 3 locks the metal tube 1 and the hose 2, and the contracted clamping tube 3 abuts against the bulge 4. Specifically: when the first elastic clamping device A and the second elastic clamping device B are combined, and the first elastic clamping device A continues to feed towards the second elastic clamping device B, the first stamping blocks 16 on both the first elastic clamping device A and the second elastic clamping device B are resisted by the clamping tube 3. This resistance forces the first stamping blocks 16 on both the first elastic clamping device A and the second elastic clamping device B to retract into the first slide groove 18a. During the retraction process, the first stamping block 16 applies pressure to the second spring 17 through the first stop rod 20, causing the second spring 17 to compress. At the same time, the elastic force of the second spring 17 is fed back to the first stamping block 16, causing the first stamping block 16 to exert pressure on the clamping tube 3, thus causing the clamping tube 3 to contract.

[0044] On the other hand, when the first elastic clamping device A and the second elastic clamping device B are combined, and the first elastic clamping device A continues to feed towards the second elastic clamping device B, both the first elastic clamping device A and the second elastic clamping device B are subjected to a vertical force. This causes the first spring 15 in the first elastic clamping device A to be compressed, which in turn causes the first slide rail 18 and the first spring seat 19 in the first elastic clamping device A to move upward. Similarly, the first spring 15 in the second elastic clamping device B is compressed, which in turn causes the first slide rail 18 and the first spring seat 19 in the second elastic clamping device B to move downward. During this process, only the force of the first stamping block 16 can be applied to the clamping tube 3 to cause the clamping tube 3 to contract. This prevents the first slide rail 18 and the first spring seat 19 in the first elastic clamping device A and the second elastic clamping device B from being unable to make the above movements and thus exerting a hard squeeze on the clamping tube 3, causing unnecessary deformation of the clamping tube 3. Therefore, this structure provides protection for the clamping tube 3, the hose 2, and the metal tube during the pressing process.
