Description

Technical Field

[0001] The invention relates to the field of automobile sunroof water pipe processing, and more specifically, to a pipe bending forming hot pressing device for processing automobile sunroof water pipes. Background Art

[0002] With the improvement of modern life quality and the trend of gradually enriching automobile configurations, sunroofs, as a configuration that is both beautiful and practical, are becoming more and more popular in passenger cars and are also favored by more and more consumers. As a part of the sunroof accessories, the sunroof water pipe assembly is responsible for draining the water accumulated in the sunroof drainage groove.

[0003] As the emission requirements of automobiles become higher and higher, the weight of the whole vehicle needs to be reduced, so the sunroof water pipe of the automobile is changed from the original common PVC / EPDM material to TPO material (the advantage of TPO material is lightness). However, the sunroof water pipe made of TPO material usually folds when passing through a curved position, which can easily cause the sunroof water pipe to be blocked. In order to make the sunroof water pipe adapt to the body of the car, the sunroof water pipe is usually subjected to hot pressing and bending treatment during production, so that the sunroof water pipe is processed into a shape that adapts to the car body structure, for example, Figure 1 The skylight water pipe 5 shown has bending parts at both ends. The bending part at one end is a front bending part 51, and the bending part at the other end is a rear bending part 52. The front bending part 51 is a continuous bending part and has an S-shaped bending structure.

[0004] In the prior art, when the above-mentioned skylight water pipe is subjected to a bending process, each bending part is usually processed in sequence through a hot press machine to make the skylight water pipe be hot-pressed into shape. However, since there are many bending parts in the skylight water pipe, the skylight water pipe needs to be placed in different models for bending according to different bending parts manually, which is not only cumbersome but also time-consuming and labor-intensive. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a bending forming hot pressing equipment for processing automobile sunroof water pipes, so that the sunroof water pipe can form a continuous bending structure after one bending, reducing the bending process and eliminating the need for manual multiple movement of the sunroof water pipe, making the bending step more convenient, saving time and effort.

[0006] The technical solution adopted by the present invention is implemented as follows: a bending tube forming hot pressing device for processing automobile sunroof water pipes, comprising a front hot pressing device, the front hot pressing device comprising a front base and a front hot pressing mechanism and a front bending mechanism arranged on the front base, the front hot pressing mechanism and the front bending mechanism are arranged in parallel;

[0010] By adopting the above technical scheme, when the skylight water pipe is subjected to press-bending processing, the skylight water pipe can be clamped by the front clamping mechanism, and the processing section of the skylight water pipe to be pressed and bent is located in the space formed between the front upper hot pressing plate and the front lower hot pressing plate, and the front upper hot pressing plate and the front lower hot pressing plate are driven to approach each other by the hot pressing lifting component, and the front upper hot pressing plate and the front lower hot pressing plate cooperate to heat the processing section of the skylight water pipe to soften the skylight water pipe. When the heating time reaches the preset time, the hot pressing lifting component drives the front upper hot pressing plate and the front lower hot pressing plate to move away from each other so that the skylight water pipe has enough space to move. At this time, the first The sliding assembly drives the front clamping mechanism to slide in the direction of the front bending mechanism. The front clamping mechanism can drive the skylight water pipe to slide during the movement. After the skylight water pipe slides to the front bending mechanism, the upper bending lifting assembly and the lower bending lifting assembly respectively drive the front upper bending die and the front lower bending die to approach each other. The skylight water pipe is bent by the cooperation of the front upper bending die and the front lower bending die. Since there are at least two front upper bending dies and at least one front lower bending die, the skylight water pipe can form a continuous bending structure after being bent once, which reduces the bending process and does not require manual movement of the skylight water pipe multiple times, making the bending step more convenient, saving time and effort.

[0014] By adopting the above-mentioned technical scheme, when processing the skylight water pipe, the skylight water pipe in a straight pipe state can be fixed on the front base by the front clamping mechanism, and the first mounting seat is driven to move by the second cylinder so that the first mounting seat drives the skylight water pipe to the front hot pressing mechanism for hot pressing. The front hot pressing mechanism heats the processing section of the skylight water pipe to soften the skylight water pipe, and then the first mounting seat is driven to move by the second cylinder so that the first mounting seat drives the skylight water pipe to the front bending mechanism. The front bending mechanism bends the softened skylight water pipe into shape, so that the heated skylight water pipe can be directly transported to the front bending mechanism for bending, so that no manual movement is required, which facilitates the processing of the skylight water pipe and reduces manpower.

[0015] As a further improvement of the present invention, the upper bending lifting assembly includes a first mounting frame arranged on the front base and an upper bending cylinder vertically arranged on the first mounting frame, the piston rod of the bending cylinder faces the front lower bending die, and the piston rod of the bending cylinder is connected to the top surface of the front upper bending die; the lower bending lifting assembly includes a lower bending cylinder vertically arranged on the front base, and the piston rod of the lower bending cylinder is connected to the bottom surface of the lower bending die.

[0016] By adopting the above-mentioned technical scheme, when the skylight water pipe is subjected to the bending step, the lower bending cylinder drives the lower bending die to rise so that the processed section of the skylight water pipe is carried on the lower bending die, and then the upper bending cylinder drives the front upper bending die to be bent downward. The two front upper bending dies cooperate with one front lower bending die, and the front clamping mechanism clamps and fixes the skylight water pipe. After the upper bending cylinder drives the upper bending die to be bent downward, the skylight water pipe is bent to form a structure with a continuous bend, thereby reducing the bending process and eliminating the need to move the skylight water pipe multiple times, making the bending step more convenient, saving time and effort.

[0017] As a further improvement of the present invention, there are two front lower bending dies and three front upper bending dies, and the two front lower bending dies are respectively located between two adjacent front upper bending dies.

[0018] By adopting the above-mentioned technical scheme, when performing the bending step, the front lower bending die supports the processing section of the skylight water pipe, and the cooperation of the three front upper bending dies and the two front lower bending dies enables continuous bends to be formed in a single bending operation, and there is no need to move the skylight water pipe to different models for single bend bending operations, which eliminates the step of manually moving the skylight water pipe, simplifies the bending steps, and makes bending more convenient; and the formation of multiple bends at one time eliminates the need to move the skylight water pipe and then position it, thereby ensuring the hot pressing accuracy of the skylight water pipe and making the bending accuracy higher.

[0019] As a further improvement of the present invention, a positioning mechanism is provided on a side of the front base opposite to the front clamping mechanism, and the positioning mechanism is used to position the skylight water pipe.

[0020] By adopting the above-mentioned technical scheme, before the bending process, the positioning mechanism positions the skylight water pipe, and then the skylight water pipe is clamped by the front clamping mechanism. After the skylight water pipe is fixed, the hot pressing and bending steps can be carried out.

Then, the two front strip plates can be driven to move in opposite directions by the two first cylinders respectively, so that the front slots on the two front strip plates are slightly shifted, thereby achieving the fixation of the skylight water pipe. The positioning mechanism cooperates with the front clamping mechanism to fix the processed section of the skylight water pipe, which is convenient for the staff to process the skylight water pipe.

[0023] As a further improvement of the present invention, a second guide rail for the second mounting seat to slide is arranged on the front base, and a third cylinder for driving the second mounting seat to slide along the length direction of the second guide rail is also arranged on the front base. The third cylinder and the second cylinder are synchronous cylinders, and the piston rod of the third cylinder is connected to the second mounting seat.

[0024] By adopting the above-mentioned technical solution, the second mounting seat is driven by the third cylinder to slide along the length direction of the guide rail, and the third cylinder and the second cylinder are synchronous cylinders, so that when the third cylinder drives the second mounting seat, the second cylinder drives the first mounting seat to slide synchronously in the same direction, thereby enabling the skylight water pipe to move back and forth between the front hot pressing mechanism and the front bending mechanism.

[0025] As a further improvement of the present invention, a fourth cylinder for driving the positioning plate to move in a direction close to and away from the front clamping mechanism is arranged on the second mounting seat, and a piston rod of the fourth cylinder is connected to the positioning plate.

[0026] By adopting the above-mentioned technical scheme, after the skylight water pipe is hot-pressed by the front hot-pressing mechanism, the second cylinder and the third cylinder respectively drive the first mounting seat and the second mounting seat to move synchronously, so that the skylight water pipe moves to the front bending mechanism for bending. After the skylight water pipe moves to the bending mechanism, the lower bending lifting assembly drives the front lower bending die to rise, so that the front lower bending die supports the skylight water pipe. At this time, the fourth cylinder drives the positioning plate to move to the side away from the front clamping mechanism to separate the positioning piece from the skylight water pipe, and then drives the front upper bending die to descend through the upper bending lifting assembly, and the front upper bending die cooperates with the front lower bending die to bend the pop-up window water pipe, so that the skylight water pipe is bent into shape, and the positioning plate is driven to move by the fourth cylinder to separate the positioning piece from the skylight water pipe, so as to prevent the positioning piece from affecting the normal bending degree of the skylight water pipe.

[0028] By adopting the above-mentioned technical solution, a hot pressing device is added to process the other end of the skylight water pipe, so that both ends of the skylight water pipe can be directly processed at a single time, which further facilitates the processing of the skylight water pipe and makes the steps for processing the skylight water pipe simpler, more convenient and quick, saving time and effort.

[0029] In summary, the present invention has the following beneficial effects:

[0030] 1. The continuous bends of the skylight water pipe are formed by one-time bending, so there is no need to process each bending part in sequence, which simplifies the bending steps and reduces the bending process.

Specifically, the oil cooling device 9 includes an oil storage tank 91 and an oil pump 92, the oil inlet of the oil pump 92 is connected to the oil storage tank 91, and the other end is connected to five branch pipes 93, and the five branch pipes 93 are respectively connected to the front upper bending die 1 411, the front upper bending die 2 412, the front upper bending die 3 413, and the front lower bending die 1 421, the front lower bending die 2 422. At the same time, the front upper bending die 1 411, the front upper bending die 2 412, the front upper bending die 3 413, the front lower bending die 1 421, the front lower bending die 2 422 are also connected to a return oil pipe (not shown in the figure), and the return oil pipe is connected to the oil storage tank 91. The front bending mechanism 4 is cooled by adding an oil cooling device 9 to avoid the front bending mechanism 4 having an excessively high temperature, which would result in a poor bending forming effect.

[0062] In this embodiment, the front hot pressing device also includes a front clamping mechanism 10 for clamping the skylight water pipe 5, and the front clamping mechanism 10 is located on one side of the front base 2. The skylight water pipe 5 is clamped by the front clamping mechanism 10 to prevent the skylight water pipe 5 from shifting and shaking during the processing process, thereby affecting the bending accuracy.

[0063] Specifically, Figure 6 and Figure 7 As shown, the front clamping mechanism 10 includes a first mounting seat 101 and two front strip plates 102 arranged in parallel on the first mounting seat 101, the two front strip plates 102 are arranged along the length direction of the front base 2, and the two front strip plates 102 are slidably connected to the top surface of the first mounting seat 101. In this embodiment, the two front strip plates 102 can slide along the length direction of the front base 2.

[0064] At least two front card slots 103 for placing the skylight water pipes 5 are formed on the two front strip plates 102, and the front card slots 103 on the two front strip plates 102 are connected one by one. In this embodiment, there are ten front card slots 103, and the ten front card slots 103 on the same front strip plate 102 are evenly spaced along the length direction of the front base 2, and the spacing between two adjacent front card slots 103 is equal to the spacing between two adjacent second pipe slots 48.

[0065] Specifically, Figure 5 and Figure 7As shown, the front slot 103 is arranged in a U shape, and the opening of the front slot 103 is upwardly directed toward the first mounting plate 71. A first limiting portion 104 communicating with the front slot 103 is provided on one of the front strip plates 102, and a second limiting portion 105 communicating with the front slot 103 is provided on the other front strip plate 102. The second limiting portion 105 is located on a side opposite to the first limiting portion 104. The first limiting portion 104 and the second limiting portion 105 are respectively used to limit the opposite sides of the skylight water pipe 5. In this embodiment, the first limiting portion 104 and the second limiting portion 105 are both grooves with arc-shaped cross-sections, and the radius of the first limiting portion 104 and the second limiting portion 105 are equal to the diameter of the skylight water pipe 5.

[0066] In addition, if Figure 7 As shown, the first mounting seat 101 is provided with two first cylinders 106 respectively used to drive the two front strip plates 102 to move in opposite directions so that the front slots 103 on the two front strip plates 102 are slightly displaced. The two first cylinders 106 are respectively located at the two ends of the first mounting seat 101, and the piston rods of the first cylinders 106 are connected to the ends of the front strip plates 102. When processing the skylight water pipe 5, the skylight water pipe 5 can be placed in the front slot 103, and the two front strip plates 102 are driven to move in opposite directions by the two cylinders respectively, so that the first limiting part 104 and the second limiting part 105 respectively contact the two sides of the skylight water pipe 5, and the skylight water pipe 5 is limited by the first limiting part 104 and the second limiting part 105 to achieve the fixation of the skylight water pipe 5.

[0067] In this embodiment, if Figure 6 and Figure 7 As shown, the first mounting seat 101 of the front clamping mechanism 10 is slidably connected to the front base 2, and the first mounting seat 101 can move back and forth between the front hot pressing mechanism 3 and the front bending mechanism 4. The front base 2 is provided with a first sliding assembly for driving the first mounting seat 101 to move along the length direction of the front base 2.

[0068] Specifically, the first sliding assembly includes a first guide rail 111 fixed on the front base 2. The cross section of the first guide rail 111 is arranged in an I-shaped manner. The first guide rail 111 is located on one side of the front base 2 and extends along the length direction of the front base 2. A first slider 112 is fixed to the bottom of the first mounting seat 101. The first slider 112 is slidably connected to the first guide rail 111. A roller (not shown in the figure) is rotatably provided on the first slider 112 to reduce the friction between the first slider 112 and the first guide roller, so that the first slider 112 slides along the first guide rail 111 more stably and smoothly. In addition, the first sliding assembly also includes a second cylinder 113 for driving the first mounting seat 101 to move along the length direction of the guide rail. The second cylinder 113 is horizontally installed on one side of the front base 2. The side wall of the first mounting seat 101 is integrally formed with a connecting block (not shown in the figure), and the piston rod of the second cylinder 113 is connected to the connecting block of the first mounting seat 101. When the second cylinder 113 is working, it can drive the first mounting seat 101 to slide along the first guide rail 111.

[0069] In addition, if Figure 6 and Figure 8 As shown, a positioning mechanism 12 is provided on the side of the front base 2 opposite to the front clamping mechanism 10 , and the positioning mechanism 12 is used to position and support the skylight water pipe 5 .

[0070] Specifically, the positioning mechanism 12 includes a second mounting seat 121 provided on the front base 2 and a positioning plate 122 provided on the second mounting seat 121. The second mounting seat 121 is arranged in a rectangular parallelepiped shape, and the second mounting seat 121 extends along the length direction of the front base 2. In this embodiment, the second mounting seat 121 can slide relative to the front base 2 and can slide along the length direction of the front base 2. The front base 2 is provided with a second guide rail 123 for the second mounting seat 121 to slide, the second guide rail 123 is arranged in an I-shape, and the second guide rail 123 extends along the length direction of the front base 2. The front base 2 is also provided with a third cylinder 124 for driving the second mounting seat 121 to slide along the length direction of the second guide rail 123, and the piston rod of the third cylinder 124 is connected to the second mounting seat 121. In this embodiment, the third cylinder 124 and the second cylinder 113 are synchronous cylinders, that is, when the second cylinder 113 drives the first mounting plate 71 to move along the length direction of the first guide rail 111, the third cylinder 124 simultaneously drives the second mounting plate 61 to move synchronously along the length direction of the second guide rail 123, and when the second cylinder 113 and the third cylinder 124 are in a retracted state, the front strip plate 102 on the first mounting seat 101 is opposite to the positioning plate 122 on the second mounting seat 121.

[0071] At the same time, if Figure 6 and Figure 8As shown, the positioning plate 122 is slidably connected to the second mounting seat 121, and the positioning plate 122 can slide along the width direction of the second mounting seat 121. The side of the positioning plate 122 facing the front downward bending die 421 is provided with ten positioning members that are plugged into and matched with the skylight water pipe 5. The positioning members are evenly spaced along the length direction of the first guide rail 111, and the spacing between two adjacent positioning members is equal to the spacing between two adjacent second pipe grooves 48. In this embodiment, the positioning member is a horizontally arranged positioning column 125, and the positioning column 125 is preferably made of an elastic rubber pad. In addition, a fourth cylinder 126 for driving the positioning plate 122 to move is provided on the second mounting seat 121, and the piston rod of the fourth cylinder 126 is connected to the side of the positioning plate 122 away from the positioning member.

[0072] like Figure 7 and Figure 8 As shown, when processing the skylight water pipe 5, Figure 5 The front clamping mechanism 10 and the positioning mechanism 12 can be driven by the second cylinder 113 and the third cylinder 124 to move synchronously to the position of the front bending mechanism 4, so that the front strip plate 102 is opposite to the positioning plate 122, and then one end of the skylight water pipe 5 is plugged into the positioning column 125, and the other end is placed on the front slot 103 of the two front strip plates 102, and the two first cylinders 106 are used to drive the two front strip plates 102 to move in the opposite direction, thereby realizing the positioning and fixation of the skylight water pipe 5.

[0073] like Figure 3 and Figure 5 As shown, the first mounting seat 101 and the second mounting seat 121 are driven by the second cylinder 113 and the third cylinder 124 to move in the same direction, so that the skylight water pipe 5 moves to the position of the front hot pressing mechanism 3. At this time, the combination Figure 4 The front lower hot pressing cylinder 35 drives the front lower hot pressing plate 31 to rise, so that the processed section of the skylight water pipe 5 is accommodated in the front pressing groove 33 of the front lower hot pressing plate 31. Then, the front upper hot pressing cylinder 34 drives the front upper hot pressing plate 32 to descend, and the skylight water pipe 5 is pressed and heated by the rising of the front lower hot pressing plate 31 and the descending of the front upper hot pressing plate 32.

[0074] like Figure 5 and Figure 6 As shown, after the heating is completed, the front upper hot pressing plate 32 rises, the front lower hot pressing plate 31 descends, and then the first mounting seat 101 is driven by the second cylinder 113 to move in the opposite direction, so that the processing section of the skylight water pipe 5 moves to the front bending mechanism 4 (combined with Figure 3 ); then the front downward bending die 422 is driven to rise by the downward bending cylinder 43, so that the skylight water pipe 5 is located in the second pipe groove 48 of the front downward bending die 422, and the downward bending die 422 supports the skylight water pipe 5;

[0075] At this time, if Figure 6and Figure 8 As shown, the fourth cylinder 126 drives the positioning plate 122 to move along the side away from the front downward bending die 1 421, so that the skylight water pipe 5 is separated from the positioning column 125. After the skylight water pipe 5 is separated from the positioning column 125, the end of the skylight water pipe 5 loses support because the skylight water pipe 5 is in a softened state after being heated. At this time, the skylight water pipe 5 falls to the second pipe groove 48 of the front downward bending die 1 421 under the action of its own gravity. The front downward bending die 1 421 supports the skylight water pipe 5, and then the front upper bending die 1 411, the front upper bending die 2 412, and the front upper bending die 3 413 are pressed down in sequence, thereby bending the processing section of the skylight water pipe 5 into shape. It should be noted that, in the present embodiment, the top surface of the front strip plate 102 is slightly higher than the highest point of the top surface of the front downward bending die 421, so that after the skylight water pipe 5 is hot-pressed, it can be normally transported to the front bending mechanism 4 for bending, thereby preventing the front downward bending die 421 from affecting the normal movement of the skylight water pipe 5.

[0076] At the same time, if Figure 6 and Figure 7 As shown, after the downward bending cylinder 43 drives the front downward bending die 422 to rise, the highest point of the top surface of the downward bending die 422 and the top surface of the front strip plate 102 are located on the same plane, and the processing section of the skylight water pipe 5 is supported by the front downward bending die 422 and the front strip plate 102 to make the force on the skylight water pipe 5 more uniform, thereby avoiding bending of the skylight water pipe 5 before bending and affecting the quality.

[0093] When the skylight water pipe 5 moves to the positions where its two ends are respectively located at the front hot pressing mechanism 3 and the rear hot pressing mechanism 14, the front lower hot pressing cylinder 35 drives the front lower hot pressing plate 31 to rise, and the rear lower hot pressing cylinder 144 drives the rear lower hot pressing plate 141 to rise, and the front lower hot pressing plate 31 and the rear lower hot pressing plate 141 receive the two ends of the skylight water pipe 5, so that the processed sections at both ends of the skylight water pipe 5 are respectively accommodated in the front pressing groove 33 of the front lower hot pressing plate 31 and the rear pressing groove 143 of the rear lower hot pressing plate 141, and then the front upper hot pressing cylinder 34 and the rear upper hot pressing cylinder 146 drive the front upper hot pressing plate 32 and the rear upper hot pressing plate 142 to press and heat in turn, so that the skylight water pipe 5 Both ends are softened, and after the heating time reaches the preset time, the front upper hot pressing plate 32, the front lower hot pressing plate 31, the rear upper hot pressing plate 142 and the rear lower hot pressing plate 141 are reset, and the third cylinder 124, the second cylinder 113, the sliding cylinder 20 and the driving cylinder 23 respectively drive the positioning mechanism 12, the front clamping mechanism 10, the rear clamping mechanism 17 and the sliding seat 22 to slide synchronously in the same direction, so that the skylight water pipe 5 is horizontally transported to the positions where the two ends of the skylight water pipe 5 are located at the front bending mechanism 4 and the rear bending mechanism 15 respectively, and the skylight water pipe 5 is aligned with the first pipe groove 47, the second pipe groove 48, the third pipe groove 153 and the fourth pipe groove 154.

[0094] Next, the front lower bending die 422 is driven to rise by the lower bending cylinder 43, so that the skylight water pipe 5 is located in the second pipe groove 48 of the front lower bending die 422, and then the skylight water pipe 5 is supported. At this time, the fourth cylinder 126 drives the positioning plate 122 to move along the side away from the front lower bending die 421, so that the skylight water pipe 5 is separated from the positioning column 125. After the skylight water pipe 5 is separated from the positioning column 125, the end of the skylight water pipe 5 falls to the second pipe groove 48 of the front lower bending die 421, and the front lower bending die 421 supports the end of the skylight water pipe 5. Then, the lifting cylinder 162 contracts and the receiving seat 161 descends, so that the skylight water pipe 5 in a softened state at the other end falls into the third pipe groove 153 of the rear lower bending die 152 due to gravity.

[0095] At this time, the front upper bending die 411, the front upper bending die 412, the front upper bending die 413 and the rear upper bending die 151 are pressed down in sequence, thereby bending the processed sections at both ends of the skylight water pipe 5 to form a bending structure with a continuous bending portion.

[0096] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
