Description

Technical Field

[0001] This invention relates to the field of automotive parts processing, specifically to an automated processing equipment for automotive brake hard tubes. Background Technology

[0002] During the production of automotive brake hoses, they need to be bent. Existing bending equipment sometimes results in collapse, flattening, and wrinkling at the bend due to the material of the hose and the degree of bending, and also presents significant bending resistance. Therefore, some hoses are supported by inserting a metal spring tube inside during bending. However, with this type of equipment, the spring tube bends along with the hose, and the resistance when pulling it out after bending is significant, easily scratching the inner wall of the hose. This allows impurities in the brake fluid to accumulate at the scratched areas, affecting brake fluid flow. Summary of the Invention

[0003] The purpose of this invention is to provide an automated processing equipment for automotive brake rigid pipes to solve the problems mentioned in the background art.

[0004] An automated processing equipment for automotive brake hard tubes includes a base plate, a tube bending device, a follow-up limiting device, an inner support assembly, a lubrication device, and an adjustment device. The base plate is provided with a tube bending device, which includes a rotating plate. A rotating shaft is fixedly connected to the bottom of the rotating plate and is rotatably connected to the base plate. A bending roller is fixedly connected to the rotating plate. The center line of the bending roller is collinear with the center line of the rotating shaft. A clamping block 1 is provided on the bending roller. A clamping block 2 is provided on the opposite side of the clamping block 1, which can approach and move away from the clamping block 1.

[0005] The follow-up limiting device includes a limiting block. When the rotating shaft rotates, it can drive the limiting block to press the pipe onto the bending roller, and the limiting block can move along the tangential direction of the bending roller together with the pipe.

[0006] The inner support assembly includes an inner support head, which has a circular hole around its circumference and an oil passage at its center that communicates with the circular hole; the inner support head is located inside the pipe fitting and remains stationary at the bend; the inner support head can also heat the pipe fitting at the bend.

[0007] The lubrication device can inject lubricating oil into the oil passage when the limiting block moves with the rotating shaft, so that the lubricating oil fills the space between the inner support head and the pipe. When the limiting block is reset, it can draw up the lubricating oil for the next injection into the oil passage.

[0008] The adjusting device is used to adjust the relative position of the pipe fitting with clamp one and clamp two, so as to adjust the bending position.

[0009] Preferably, the pipe bending device further includes a motor and a cylinder. The output shaft of the motor is fixedly connected to the rotating shaft. The cylinder is fixedly connected to the rotating plate, and its output shaft is fixedly connected to a connecting block. The connecting block is slidably connected to the rotating plate and fixedly connected to the clamping block.

[0010] Preferably, the follow-up limiting device further includes a gear and a rack. The gear is located below the rotating plate and is fixedly connected to the rotating shaft. The rack meshes with the gear and is fixedly connected to the limiting block. The rack is slidably connected to the base plate.

[0011] Preferably, the clamping block one, clamping block two, bending roller and limiting block are all provided with contour grooves for accommodating the pipe fittings.

[0012] Preferably, the inner support assembly further includes an outer sleeve and a flange. The inner support head is located at the front end of the outer sleeve. A flexible hose is provided inside the outer sleeve. An oil inlet pipe is provided at the center of the flange. One end of the flexible hose is connected to the oil passage of the inner support head, and the other end is connected to the oil inlet pipe of the flange. The flange is also fixedly connected to the rear end of the outer sleeve. The rear end of the outer sleeve is hinged to a bracket on the base plate.

[0013] Preferably, an induction coil is embedded in the inner support head, and the inner support head is made of non-metallic material.

[0014] Preferably, the lubrication device includes an injection cylinder and a piston rod. The piston rod is fixedly connected to a rack and slides in a sealed manner within the injection cylinder. The injection cylinder is fixedly connected to a base plate. The injection cylinder is provided with an oil port, which is connected to a three-way pipe. The three-way pipe is also connected to an oil suction pipe and an oil outlet pipe. Both the oil suction pipe and the oil outlet pipe are provided with one-way valves. The oil suction pipe is connected to an oil tank, and the oil outlet pipe is connected to an oil inlet pipe.

[0015] Preferably, the adjustment device includes a limiting frame and a linear module. The limiting frame is provided with a through groove for the outer sleeve to pass through. The limiting frame is connected to the slide of the linear module, and the linear module is fixedly connected to the base plate.

[0016] The advantages of this invention are:

[0017] By setting an internal support component inside the pipe fitting, and ensuring that the internal support head is always at the bend, the support function of the pipe fitting can be ensured on the one hand, and the internal support head can be ensured to be at the initial end of the bend after the pipe fitting is bent, so that the internal support head can be easily pulled out of the pipe fitting.

[0018] An oil channel and a round hole are added to the inner support head to work with the lubrication device. This allows lubricating oil to be filled between the inner support head and the pipe during bending, reducing friction and preventing the pipe from being scratched. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 5 As shown, an automated processing equipment for automotive brake hard tubes includes a base plate 1, a tube bending device 2, a follow-up limiting device 3, an inner support assembly 4, a lubrication device 5, and an adjustment device 6. The base plate 1 is provided with the tube bending device 2, which includes a rotating plate 21. The bottom of the rotating plate 21 is fixedly connected to a rotating shaft 22, which is rotatably connected to the base plate 1. A bending roller 23 is fixedly connected to the rotating plate 21. The center line of the bending roller 23 is collinear with the center line of the rotating shaft 22. A clamping block 24 is provided on the bending roller 23. A clamping block 25 is provided on the opposite side of the clamping block 24, which can approach and move away from the clamping block 24.

[0031] The follow-up limiting device 3 includes a limiting block 31. When the rotating shaft 22 rotates, it can drive the limiting block 31 to press the pipe onto the bending roller 23, and the limiting block 31 can move along the tangential direction of the bending roller 23 together with the pipe.

[0032] The inner support assembly 4 includes an inner support head 41, which has a circular hole 411 around its circumference and an oil passage 412 communicating with the circular hole 411 at its center. The inner support head 41 is located inside the pipe and remains stationary at the bend, which is used to prevent the pipe from collapsing or wrinkling when it is bent. The inner support head 41 can also heat the pipe at the bend.

[0033] The lubrication device 5 can inject lubricating oil into the oil passage 412 when the limiting block 31 moves with the rotating shaft 22, so that the lubricating oil fills the space between the inner support head 41 and the pipe. When the limiting block 31 is reset, it can draw up the lubricating oil for the next injection into the oil passage 412.

[0034] The adjusting device 6 is used to adjust the relative position of the pipe fitting with clamp 24 and clamp 25 to adjust the bending position.

[0035] In this embodiment, the pipe bending device 2 further includes a motor 26 and a cylinder 27. The output shaft of the motor 26 is fixedly connected to the rotating shaft 22. The cylinder 27 is fixedly connected to the rotating plate 21, and its output shaft is fixedly connected to a connecting block 28. The connecting block 28 is slidably connected to the rotating plate 21 and fixedly connected to the clamping block 25.

[0036] In this embodiment, the follow-up limiting device 3 further includes a gear 32 and a rack 33. The gear 32 is located below the rotating plate 21 and is fixedly connected to the rotating shaft 22. The rack 33 meshes with the gear 32 and is fixedly connected to the limiting block 31. The rack 33 is slidably connected to the base plate 1.

[0037] In this embodiment, the clamping block 24, clamping block 25, bending roller 23, and limiting block 31 are all provided with contour grooves to accommodate the pipe fitting. The shape of the contour groove matches the pipe fitting.

[0038] In this embodiment, the inner support assembly 4 further includes an outer sleeve 42 and a flange 43. The inner support head 41 is located at the front end of the outer sleeve 42. A flexible hose 44 is provided inside the outer sleeve 42. An oil inlet pipe 431 is provided at the center of the flange 43. One end of the flexible hose 44 is connected to the oil passage 412 of the inner support head 41, and the other end is connected to the oil inlet pipe 431 of the flange 43. The flange 43 is also fixedly connected to the rear end of the outer sleeve 42. The rear end of the outer sleeve 42 is hinged to a bracket 46 on the base plate 1. This allows one end of the outer sleeve 42 to be fixed, while the other end can move slightly in the vertical plane.

[0039] In this embodiment, an induction coil 45 is embedded in the inner support head 41, and the inner support head 41 is made of non-metallic material.

[0040] In this embodiment, the lubrication device 5 includes an injection cylinder 51 and a piston rod 52. The piston rod 52 is fixedly connected to the rack 33 and slides in a sealed manner within the injection cylinder 51. The injection cylinder 51 is fixedly connected to the base plate 1. The injection cylinder 51 is provided with an oil port 511, which is connected to a three-way pipe. The three-way pipe is also connected to an oil suction pipe and an oil outlet pipe. Both the oil suction pipe and the oil outlet pipe are equipped with one-way valves, so that the oil suction pipe only sucks in oil and the oil outlet pipe only discharges oil. The oil suction pipe is connected to an oil tank, and the oil outlet pipe is connected to an oil inlet pipe 431. The three-way pipe, oil suction pipe, oil outlet pipe, and oil tank are existing technologies and are all shown in the figure.

[0041] In this embodiment, the adjustment device 6 includes a limiting frame 61 and a linear module 62. The limiting frame 61 is provided with a through groove 611 for the outer tube 42 to pass through, which facilitates the fine adjustment of the outer tube 42 in the vertical plane. The limiting frame 61 is connected to the slide table of the linear module 62, and the linear module 62 is fixedly connected to the base plate 1.

[0042] Working process and its principle:

[0043] Before bending, clamp 1 24 and clamp 2 25 are in a far apart state. According to the required bending position of the pipe, the position of the limiting bracket 61 on the outer tube 42 is adjusted by the straight module 62, thereby changing the limit length of the pipe fitting into the outer tube 42 and indirectly changing the bending position. Then the pipe fitting is fitted onto the outside of the outer tube 42, with one end of the pipe fitting abutting against the limiting bracket 61 and the other end placed between clamp 1 24 and clamp 2 25.

[0044] Start cylinder 27, which drives clamping block 25 to move towards clamping block 24 via connecting block 28, so that the pipe is clamped between clamping block 24 and clamping block 25.

[0045] Then the motor 26 starts and drives the rotating shaft 22 to rotate. The rotation of the rotating shaft 22 causes the rotating plate 21 to rotate clockwise. The clamping block 1 24 and clamping block 25 rotate accordingly. The pipe rotates around the bending roller 23. When the limiting block 31 restricts the rotation of the rest of the pipe, the pipe can be bent.

[0046] During the bending process described above, the rotation of the shaft 22 will also drive the gear 32 to rotate. The gear 32 drives the rack 33 to move, so that the limiting block 31 can move along the tangent direction of the bending roller 23 to maintain the limiting of the pipe. During the bending process, the inner support head 41 is always in the bending area to support the bending part and does not move with the pipe.

[0047] The movement of rack 33 also pushes piston rod 52 to move, thereby squeezing out the oil inside injection cylinder 51 and passing it through oil outlet pipe, oil inlet pipe 431, hose 44, oil passage 412 and through hole in sequence, and finally filling the space between inner support head 41 and pipe fitting, thereby reducing friction.

[0048] In addition, during the bending process, the induction coil 45 is energized, which can heat the bending area, promote the deformation of the pipe, reduce bending resistance, and make the bending process smoother.

[0049] After bending, the pipe can be pulled out, allowing the inner support head 41 to detach from the pipe. When the rack 33 resets, it will drive the piston rod 52 to reset, thereby drawing the oil from the oil tank into the injection cylinder 51 through the oil suction pipe for temporary storage for the next use.

[0050] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or equivalent to the scope of this invention are included in this invention.
