Description

Technical Field

[0001] This invention relates to pipe fitting production equipment, and more specifically to a multi-position stamping fixture for pipe fitting supports. Background Technology

[0002] Automotive piping is an important component of a vehicle, primarily used to achieve functions such as fluid transmission, control, and safety protection in various systems. For example: In the cooling system, coolant piping circulates coolant to maintain the engine's normal operating temperature. In the lubrication system, lubricating oil delivery piping delivers lubricating oil to various engine components, reducing friction. In the air conditioning system, refrigerant piping transports refrigerant to maintain a comfortable temperature inside the vehicle.

[0003] To increase the stability and position of pipe fittings installed on automobiles, multiple parallel pipe fittings need to be fixed with brackets in some locations. The brackets include upper and lower sleeves. The upper sleeve has upper wings on both sides, and the lower sleeve has lower wings on both sides. Currently, the brackets are installed by setting threaded holes on the upper wings of the upper sleeve and the lower wings of the lower sleeve. After the upper and lower sleeves clamp the pipe fittings, screws are used to connect to the threaded holes on the upper and lower wings, thereby allowing the upper and lower sleeves to hold the pipe fittings tightly.

[0004] Based on the above installation method, not only are screw holes required on the upper and lower fins, but each screw must also be connected to the threaded hole during assembly, which takes at least one minute to assemble each product. Furthermore, although the upper and lower sleeves are secured with screws, vibrations generated during vehicle operation can easily cause the screws to loosen, leading to the pipes swaying under vibration and resulting in positioning failure. Summary of the Invention

[0005] This invention provides a multi-position stamping fixture for pipe fitting supports. This invention features fast assembly speed and good stability of the support and pipe fitting after assembly.

[0006] A multi-position stamping fixture for a pipe fitting support includes an upper sleeve and a lower sleeve. An upper wing is fixed to each side of the upper sleeve, and a lower wing is fixed to each side of the lower sleeve. Both the upper and lower wings include a wing root, a wing middle, and a wing tip. One end of the wing middle is fixed to the wing root, and the other end of the wing middle is fixed to the wing tip. A first snap fastener is provided on the wing root of the lower wing, and a second snap fastener is provided on the wing tip. The stamping fixture includes: The first support has a first groove for engaging with the lower sleeve, a first slope for supporting the wing root and wing middle of the lower wing, the first slope being located on both sides of the first groove, a second slope for supporting the wing tip of the lower wing, and a first positioning component for positioning the wing tips of the upper and lower wing. The pre-assembled pipe fittings and supports are pressed into the clamping assembly of the first support; The first presser bends and presses against the first stamping assembly of the upper wing; The second press buckle bends and presses against the second stamping assembly of the upper wing.

[0007] When pressing multiple buckles on the bracket, this invention only requires pre-assembling the bracket and pipe fitting, and then positioning the bracket with the tooling. After that, each linear actuator can be turned on, and each stamping component can bend and deform the corresponding buckle to press the upper wing, thereby fastening the upper wing and the lower wing into one piece. The upper wing is integrally formed with the upper clamping sleeve, and the lower wing is integrally formed with the lower clamping sleeve. With the upper wing and the lower wing fastened into one piece, the upper clamping sleeve and the lower clamping sleeve clamp the pipe fitting.

[0008] In this invention, the method of fastening the upper and lower wings together avoids the use of threaded holes and screws. Instead, it directly uses the method of stamping each buckle. The upper wing is pressed by the bent buckle, thereby fastening the upper and lower wings together. This method can simultaneously start each stamping component to stamp the buckles at the corresponding positions, which not only makes the assembly speed fast, but also ensures that the upper wing is clamped between the buckle and the lower wing after stamping. When the pipe is used in a car, even when faced with the vibration force during driving, the upper and lower sleeves will not loosen, which has the advantage of good stability.

Detailed Implementation

[0018] like Figures 1 to 7 As shown, the present invention provides a multi-position stamping fixture for a pipe fitting support. The support includes an upper clamp 1 and a lower clamp 2. The upper clamp 1 includes a semi-circular upper clamping portion 1a. In this embodiment, there are two upper clamping portions 1a, and an upper spacer portion 1b is fixed between the two upper clamping portions 1a. The upper spacer portion 1b is a plate-shaped component. The lower clamp 2 includes a semi-circular lower clamping portion 2a. In this embodiment, there are two lower clamping portions 2a, and a lower spacer portion 2b is fixed between the two lower clamping portions 2a. The lower spacer portion 2b is a plate-shaped component. After the upper clamp 1 and the lower clamp 2 are engaged, the upper clamping portions 1a and the lower clamping portions 2a engage to form a complete pipe-shaped component, and the upper clamping portions 1a and the lower clamping portions 2a hold the pipe fitting A.

[0019] An upper wing 3 is fixed to each side of the upper clip 1, and a lower wing 4 is fixed to each side of the lower clip 2. Both the upper wing 3 and the lower wing 4 are wing-shaped components. The upper wing 3 and the upper clip 1 are integrally formed, and the lower wing 4 and the lower clip 2 are integrally formed. An upper wing 3 is fixed to the outer wall of each upper clip 1a, and a lower wing 4 is fixed to the outer wall of each lower clip 2a.

[0020] Both the upper wing 3 and the lower wing 4 include a wing root 4a, a wing middle 4b, and a wing tip 4c. The wing root 4a of the upper wing 3 is fixed to the upper clamping part 1a, and the wing root 4a of the lower wing 4 is fixed to the lower clamping part 2a. One end of the wing middle 4b is fixed to the wing root 4a, and the other end of the wing middle 4b is fixed to the wing tip 4c. The wing root 4a of the lower wing 4 is provided with a first snap fastener 5, which is originally L-shaped. One end of the first snap fastener 5 is fixed to the side wall of the lower wing 4, and the other end of the first snap fastener 5 is located above the lower wing 4. The wing tip 4c of the lower wing 4 is provided with a second snap fastener 6, which is originally L-shaped. One end of the second snap fastener 6 is fixed to the side wall of the lower wing 4, and the other end of the second snap fastener 6 is located above the lower wing 4. Both the upper wing 3 and the lower wing 4 are provided with through holes 4d, which are located on the wing tip 4c.

[0021] The stamping fixture includes a first support 11, a clamping assembly, a first stamping assembly, a second stamping assembly, and a third stamping assembly. The following is a detailed description of each part of the stamping fixture and the relationship between them.

[0022] The first support 11 is provided with a first groove 11a for engaging with the lower sleeve 2. In this embodiment, there are two first grooves 11a, and a partition 11g is formed between the two first grooves 11a. The first support 11 is provided with a first limiting block 11h and a second limiting block 11i for limiting the upper spacer 1b and the lower spacer 2b. The first limiting block 11h is fixed to the partition 11g, and the second limiting block 11i is preferably fixed to the side wall of the first support 11. A groove is formed between the first limiting block 11h, the second limiting block 11i, and the partition 11g. After the upper spacer 1b and the lower spacer 2b engage with the groove, the partition 11g provides support for the lower spacer 2b, and the first limiting block 11h and the second limiting block 11i restrict the position of the upper spacer 1b and the lower spacer 2b, preventing the upper spacer 1b and the lower spacer 2b from displacing, thereby improving the positional accuracy of the upper sleeve 1 and the lower sleeve 2 after engagement.

[0023] The first support 11 is provided with a first slope 11b that supports the wing root 4a and wing middle 4b of the lower wing 4. The first slope 11b is located on both sides of the first groove 11a, that is, a first slope 11b is provided on each side of the first groove 11a. The wing root 4a and wing middle 4b are in contact with the first slope 11b. The first support 11 is provided with a second slope 11c that supports the wing tip 4c of the lower wing 4. The second slope 11c is located outside the first slope 11b, and the wing tip 4c is in contact with the second slope 11c.

[0024] The first support 11 is also provided with a first positioning component for positioning the wingtips 4c of the upper wing 3 and the lower wing 4. In this embodiment, the first positioning component includes a first positioning block 11d and a second positioning block 11e. The first positioning block 11d and the second positioning block 11e are respectively fixed to the first support 11. The first positioning block 11d is located on one side of the second slope 11c, and the second positioning block 11e is located on the other side of the second slope 11c. The wingtips 4c are located between the first positioning block 11d and the second positioning block 11e. Thus, the first positioning block 11d and the second positioning block 11e position the wingtips 4c of the upper wing 3 and the lower wing 4, preventing the wingtips 4c of the upper wing 3 and the lower wing 4 from displacing, thereby improving the positional accuracy of the upper wing 3 and the lower wing 4 after they are engaged.

[0025] The first support 11 is provided with an insert block 11j, which mates with the first groove 11a. The insert block 11j is also provided with a third groove 11k for mates with the pipe fitting A. To prevent the pipe fitting A from being deformed or damaged when the clamping assembly applies pressure to the support, a buffer sleeve B is fitted onto the pipe fitting A. The buffer sleeve B can be made of rubber, and the upper clamp 1 and the lower clamp 2 clamp the buffer sleeve B. After the buffer sleeve B is installed on the pipe fitting A, since both the buffer sleeve B and the lower clamp 2 have thickness, without the installation of the insert block 11j, when the lower clamp 2 is engaged with the first groove 11a, the pipe fitting A is suspended above the first groove 11a, that is, the pipe fitting A cannot fit against the wall of the first groove 11a. Therefore, in this embodiment, the insert block 11j is installed in the first groove 11a, so that a part of the pipe fitting A fits against the groove wall of the third groove 11k, thereby making the pipe fitting A supported by the insert block 11j. This allows both the pipe fitting A and the support to obtain corresponding support, and when the clamping assembly applies pressure to the support, it helps to make the pipe fitting A and the support bear force evenly.

[0026] The clamping assembly presses the pre-assembled pipe fitting A and bracket onto the first support 11. Pre-assembly of pipe fitting A and bracket means that after the buffer sleeve B on pipe fitting A is clamped by the upper clamp 1 and lower clamp 2, the bracket engages with the first groove 11a, and pipe fitting A engages with the third groove 11k. At this time, the upper clamp 1, lower clamp 2, and buffer sleeve B are only in contact, not yet tightly fastened together. The clamping assembly includes a second support 12, a lifting actuator 13, and a pressure head 14. The lifting actuator 13 is fixed to the second support 12. The lifting actuator 13 can be a linear actuator such as a cylinder or hydraulic cylinder. In this embodiment, a cylinder is preferred for the lifting actuator 13. Both the lifting actuator 13 and the pressure head 14 are located above the first support 11. One end of the pressure head 14 is fixed to the power output end of the lifting actuator 13, and the other end of the pressure head 14 is provided with a second groove 14a that engages with the upper clamp 1.

[0027] When it is necessary to press the clamping assembly to press the pipe fitting A and the bracket onto the first support 11, the lifting drive 13 is started. The lifting drive 13 drives the pressure head 14 to feed upward into the upper clamp 1. The pressure head 14 applies pressure to the upper clamp 1. After the pressure head 14 reaches the specified stroke, the lifting drive 13 stops working. At this time, the pressure of the pressure head 14 on the upper clamp 1 is maintained.

[0028] The first stamping assembly, the second stamping assembly, the third stamping assembly, and the clamping assembly are distributed around the first support 11, for example, from... Figure 1 In the middle view, the first stamping assembly is located on the left side of the first support 11, the second stamping assembly is located on the right side of the first support 11, the third stamping assembly is located on the front side of the first support 11, and the second support 12 in the clamping assembly is located on the rear side of the first support 11. Since the first stamping assembly and the second stamping assembly are located on opposite sides of the first support 11, when the first stamping assembly and the second stamping assembly are working, the first stamping assembly and the second stamping assembly move towards each other. The directions of the forces generated by the first stamping assembly and the second stamping assembly on the bracket are opposite, thereby avoiding the bracket displacement that may occur when the two forces are in the same direction.

[0029] The first stamping assembly bends the first snap fastener 5 to press against the upper wing 3. The first stamping assembly includes a first linear actuator 15, a first guide seat 16, a first slider 17, and a first stamping head 18 that bends the first snap fastener 5 to press against the upper wing 3. The first linear actuator 15 can be a cylinder, hydraulic cylinder, or other linear actuator. The power output end of the first linear actuator 15 is connected to the first slider 17. The first slider 17 is slidably engaged with the first guide seat 16. The first stamping head 18 is fixed to the first slider 17. The movement direction of the first stamping head 18 is perpendicular to the first snap fastener 5 in its original state. Therefore, when the first linear actuator 15 drives the first stamping head 18 to feed towards the first snap fastener 5, the force exerted by the first stamping head 18 on the first snap fastener 5 causes the first snap fastener 5 to bend, thus clamping the first part of the upper wing 3 between the first snap fastener 5 and the lower wing 4.

[0030] The second stamping assembly bends the second snap fastener 6 to press against the upper wing 3. The second stamping assembly includes a second linear actuator 18a, a second guide seat 19, a second slider 20, and a second stamping head 21 that bends the second snap fastener 6 to press against the upper wing 3. The second linear actuator 18a can be a cylinder, hydraulic cylinder, or other linear actuator. The power output end of the second linear actuator 18a is connected to the second slider 20, which is slidably connected to the second guide seat 19. One end of the second stamping head 21 is fixed to the second slider 20. The movement direction of the second stamping head 21 is perpendicular to the original form of the second snap fastener 6. Therefore, when the second linear actuator 18a drives the second stamping head 21 to feed towards the second snap fastener 6, the force exerted by the second stamping head 21 on the second snap fastener 6 causes it to bend, clamping the second part of the upper wing 3 between the second snap fastener 6 and the lower wing 4.

[0031] Since there are two lower wings 4, in order to enhance the fastening force of the upper wing 3 and the lower wing 4, in this embodiment, a third buckle 7 is fixed to the wing root 4a of the first lower wing 4, which is arranged opposite to the first buckle 5 on the wing root 4a. That is, the first buckle 5 is fixed on one side of the wing root 4a, and the third buckle 7 is fixed on the other side of the wing root 4a. The original shape of the third buckle 7 is preferably L-shaped. One end of the third buckle 7 is fixed to the side wall of the wing root 4a, and the other end of the third buckle 7 is located above the lower wing 4. In order to enable the third snap fastener 7 to also press down on the upper wing 3, the second stamping assembly is also provided with an extended stamping head 22 for bending the third snap fastener 7 to press down on the upper wing 3. The extended stamping head 22 is fixed to the other end of the second stamping head 21 or the second slider 20. In this embodiment, the extended stamping head 22 is preferably fixed to the other end of the second stamping head 21. When the second linear actuator 18a drives the second stamping head 21 to feed towards the second snap fastener 6, the extended stamping head 22 simultaneously feeds towards the third snap fastener 7. The force generated by the extended stamping head 22 on the third snap fastener 7 causes the third snap fastener 7 to bend, so that the third part of the upper wing 3 is clamped between the third snap fastener 7 and the lower wing 4.

[0032] In this embodiment, a fourth snap fastener 8 is fixed on the wing root 4a or wing middle 4b of the second lower wing 4, located on one side of the first snap fastener 5 on the wing root 4a. The original shape of the fourth snap fastener 8 is preferably L-shaped. One end of the fourth snap fastener 8 is fixed to the side wall of the wing root 4a, and the other end of the fourth snap fastener 8 is located above the lower wing 4. In order to enable the fourth snap fastener 8 to also press down on the upper wing 3, this embodiment also provides a third stamping assembly that allows the fourth snap fastener 8 to bend and press down on the upper wing 3.

[0033] The third stamping assembly includes a third linear actuator 23, a third guide seat 24, a third slider 25, and a third stamping head 26 that bends the fourth snap fastener 8 and presses it against the upper wing 3. The power output end of the third linear actuator 23 is connected to the third slider 25, and the third slider 25 is connected to the third guide seat 24 in a sliding fit. One end of the third stamping head 26 is fixed to the third slider 25. Since the wing root 4a and the wing middle 4b are in contact with the first slope 11b, that is, the wing root 4a and the wing middle 4b are inclined relative to the horizontal direction, the fourth snap fastener 8 is also inclined relative to the horizontal direction. In order to make the movement direction of the third stamping head 26 perpendicular to the fourth snap fastener 8, the movement direction of the third slider 25 during operation forms an angle with the horizontal direction.

[0034] In this embodiment, the third guide seat 24 is a wedge seat, and the lower surface of the third guide seat 24 is a slope. When the third guide seat 24 is installed on the base plate 28, the upper surface of the third guide seat 24 is inclined to the upper surface of the base plate 28 (the upper surface of the base plate 28 is a horizontal plane). Therefore, a first hinge seat 29 is provided on the base plate 28, and a second hinge seat 30 is provided on the third slider 25. The third linear actuator 23 is hinged to the first hinge seat 29, and the power output end of the third linear actuator 23 is hinged to the second hinge seat 30, so that the third linear actuator 23 can adapt to the change of slope when it works.

[0035] Preferably, in order to prevent displacement of the upper wing 3 and lower wing 4 when stamping each buckle, through holes 4d are provided on both the upper wing 3 and lower wing 4, and positioning pins 11f are provided on the first support 11. The positioning pins 11f cooperate with the through holes 4d on the upper wing 3 and lower wing 4, thereby restricting the degrees of freedom of the upper wing 3 and lower wing 4 in the front-back, left-right and right directions.

[0036] Preferably, the system further includes a positioning component 27 for positioning the end of pipe fitting A, and the positioning component 27 is fixed to the clamping component. The positioning component 27 is fixed to the second support 12. The positioning component 27 consists of a connecting seat and a positioning plate. The connecting seat is fixedly connected to the second support 12, and the positioning plate is fixed to the connecting seat. In this embodiment, there are two pipe fittings A. After stamping, the connecting plate C is first welded to the two pipe fittings A. While the bracket is combined with the positioning column 11f, the end of one of the pipe fittings A automatically forms abutment with the positioning plate, thereby preventing the pipe fitting A from shifting during the stamping process.

[0037] The process of stamping the buckles on the bracket in this invention is as follows: S1, after the pipe fittings and brackets are pre-assembled, the lower sleeve 2 and the first groove 11a are engaged, the lower spacer 2b and the partition 11g are engaged, the wing root 4a and the wing middle 4b in the lower wing 4 are engaged with the first slope 11b, the positioning post 11f passes through the through hole 4d on the upper wing 3 and the lower wing 4, the upper wing 3 and the lower wing 4 are positioned by the positioning post 11f, and at the same time the first positioning block 11d and the second positioning block 11e restrict the position of the side wall of the upper wing 3 and the lower wing 4; the pipe fitting A is engaged with the third groove 11k, and the end of the pipe fitting A abuts against the positioning assembly 27.

[0038] S2, start the lifting drive 13 to work. The lifting drive 13 drives the pressure head 14 to feed upward into the upper clamp 1. The pressure head 14 applies pressure to the upper clamp 1. After the pressure head 14 reaches the required feed amount, the lifting drive 13 stops working, and the bracket and pipe are clamped between the pressure head 14 and the first support 11.

[0039] S3, the first linear driver 15 and the second linear driver 18a are started to work. The first linear driver 15 drives the first slider 17 to move linearly. The first slider 17 drives the first punch head 18 to move linearly. Since the movement direction of the first punch head 18 is perpendicular to the first snap fastener 5 in its original form, when the first linear driver 15 drives the first punch head 18 to feed towards the first snap fastener 5, the force generated by the first punch head 18 on the first snap fastener 5 causes the first snap fastener 5 to bend, so that the first part of the upper wing 3 is clamped between the first snap fastener 5 and the lower wing 4.

[0040] The second linear actuator 18a drives the second slider 20 to move linearly. The second slider 20 drives the second punch head 21 and the extended punch head 22 to move linearly. Since the movement direction of the second punch head 21 is perpendicular to the second snap 6 in its original form, and the movement direction of the extended punch head 22 is perpendicular to the third snap 7 in its original form, when the second linear actuator 18a drives the second punch head 21 to feed towards the second snap 6, the force exerted by the second punch head 21 on the second snap 6 causes the second snap 6 to bend, thereby clamping the second part of the upper wing 3 between the second snap 6 and the lower wing 4. After the extended punch head 22 feeds towards the third snap 7, the force exerted by the extended punch head 22 on the third snap 7 causes the third snap 7 to bend, thereby clamping the third part of the upper wing 3 between the third snap 7 and the lower wing 4.

[0041] S4, start the third linear actuator 23 (the third linear actuator 23 can be started simultaneously with the first linear actuator 15 and the second linear actuator 18a). The third linear actuator 23 drives the third slider 25 to move linearly along the third guide seat 24. The third slider 25 drives the third punch head 26 to move linearly along the third guide seat 24. Since the movement direction of the third punch head 26 is perpendicular to the fourth snap 8 in the original form, when the third linear actuator 23 drives the third punch head 26 to feed towards the fourth snap 8, the force generated by the third punch head 26 on the fourth snap 8 causes the fourth snap 8 to bend, so that the fourth part of the upper wing 3 is clamped between the fourth snap 8 and the lower wing 4.

[0042] As can be seen from the above process, when the present invention presses on multiple buckles on the bracket, it is only necessary to pre-assemble the bracket and the pipe fitting, and then coordinate the bracket with the tooling to obtain positioning. Then, each linear actuator can be turned on, and each stamping component can bend and deform the corresponding buckle to press the upper wing 3, thereby making the upper wing 3 and the lower wing 4 fastened together. The upper wing 3 is integrally formed with the upper clamping sleeve 1, and the lower wing 4 is integrally formed with the lower clamping sleeve 2. With the upper wing 3 and the lower wing 4 fastened together, the upper clamping sleeve 1 and the lower clamping sleeve 2 clamp the pipe fitting A.

[0043] Finally, it should be noted that the above-described embodiments are merely preferred embodiments of the present invention used to illustrate the technical solutions of the present invention, and are not intended to limit them, much less limit the scope of protection of the present invention; although the invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to depart from the scope of protection of the claims.
