Description

Technical Field

[0001] This invention relates to the field of flange pipe manufacturing technology, specifically to an assembly equipment and manufacturing process for rubber pipes and steel flanges. Background Technology

[0002] During pipeline construction, rubber pipes are usually used for installation. Two sections of rubber pipe are usually connected by flanges to form a flanged rubber pipe. The flanged rubber pipe is usually assembled manually from the rubber pipe and the flange. The rubber pipe consists of an inner rubber pipe, a skeleton layer, a steel wire layer and an outer rubber layer.

[0003] Currently, the assembly methods between rubber hoses and flanges typically include flange connections, quick coupling connections, clamp connections, compression connections, and pipe fitting connections. Among these, flange connections are the most common. This involves assembling flanges at one end of the rubber hose and on the flange, and then securing them together with bolts and nuts. However, in some construction environments with high sealing requirements, crimp connections are necessary. This involves compressing and fixing a metal sleeve onto the rubber hose to secure it to the flange. Currently, however, there is a lack of effective assembly equipment for this method, resulting in low production efficiency. Furthermore, manual assembly makes it difficult to guarantee airtightness, and production quality is hard to meet standards. Summary of the Invention

[0041] 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.

[0042] Please see Figure 1-9 As shown, an assembly device for rubber hose and steel flange includes an operating table 1, on which a rubber hose fixing device, a sleeve clamping device and a flange support device are sequentially arranged.

[0043] Specifically, the rubber tube fixing device includes a rubber tube positioning component 3 and a rubber tube support component 4 acting on the rubber tube 2. The rubber tube positioning component 3 is located on one side of the operating table 1, and the rubber tube support component 4 is installed on the table surface of the operating table 1.

[0044] Specifically, the rubber tube positioning assembly 3 includes a fixed post 301, a telescopic rod 302 is provided on one side of the fixed post 301, and a telescopic fixing block 303 is provided at one end of the telescopic rod 302. The rubber tube support assembly 4 includes a telescopic base 401, and two sets of rotating rollers 402 are provided on the telescopic base 401.

[0045] In this invention, the rubber tube fixing device is used to fix the rubber tube 2. The rubber tube positioning component 3 and the rubber tube support component 4 are used to fix the rubber tube 2 relatively stably. The rubber tube positioning component 3 mainly positions the rubber tube 2 to calibrate its position for easy operation. The rubber tube support component 4 mainly supports the body of the rubber tube 2 and can also rotate the rubber tube 2 using the rotating roller 402 to change its orientation. The two components work together to stabilize the rubber tube 2.

[0046] Specifically, the sleeve clamping device includes a mounting plate 5 vertically mounted on the operating table 1. The mounting plate 5 has a receiving area 6 in the middle. Two sets of slide rails 601 are provided on the inner wall of the receiving area 6. A compaction component 7 that moves along the slide rails 601 is installed in the two sets of slide rails 601.

[0047] In this invention, the sleeve clamping device mainly functions on the metal sleeve, pressing the metal sleeve firmly onto the rubber tube 2 and the steel flange 9, further tightening the connection between the rubber tube 2 and the steel flange 9, ensuring its airtightness meets the standard, and preventing air leakage during use. The receiving area 6 in the sleeve clamping device is used to accommodate the operating space of the metal sleeve between the rubber tube 2 and the steel flange 9, so as to compress the metal sleeve onto the rubber tube 2 and the steel flange 9. Two sets of slide rails 601 are provided on the inner wall of the receiving area 6 to guide the compaction component 7. The compaction component 7 is used to compress the metal sleeve in the overall sleeve clamping device. The slide rails 601 guide the compaction component 7 to rotate in the receiving area 6, so that it can compact the metal sleeve from all directions, ultimately making the sleeve completely fit against the outside of the rubber tube 2, so that the rubber tube 2 and the steel flange 9 are tightly fitted.

[0048] Specifically, the flange support device includes a movable arm 8 located on the other side of the top of the operating table 1. One side of the movable arm 8 is connected to a telescopic support assembly 10 that extends into the steel flange 9. The center lines of the telescopic support assembly 10 and the telescopic rod 302 both pass horizontally through the midpoint of the receiving area 6.

[0049] The flange support device mainly fixes the steel flange to the compaction end of the rubber tube 2, keeping it stable during the compaction process and preventing wobbling during the metal sleeve compaction. During the rotational compaction process of the compaction component, the steel flange 9 can be stably positioned at the center of the receiving area 6. The flange support device mainly relies on the telescopic support component 10 to fix the steel flange 9. Throughout the fixing process, the flange remains stable at the center position. The movable arm 8 in the flange support device can be rotated to a horizontal position before fixing, making it easy to place the flange 9 on the telescopic support component 10. After placement, it can be fixed. The operation is simple.

[0050] Specifically, the compaction assembly 7 includes two sets of sliders 701 that cooperate with the slide rail 601. The top of each set of sliders 701 is connected to a telescopic member 702, and a compaction roller 703 is connected between the two sets of telescopic members 702.

[0051] Specifically, the bottom of the slider 701 is set to an arc shape corresponding to the internal shape of the slide rail 601. The compaction roller 703 is installed between the two sets of telescopic parts 702 and is kept at a certain distance from the inner wall of the receiving area 6. Its movement trajectory always points to the center of the receiving area 6.

[0052] In this invention, the compaction component 7 compresses the metal sleeve through the rolling compaction roller 703. At the same time, the compaction roller 703 slides in the slide rail 601 following the slider 701. The compaction roller 703 is installed between two sets of telescopic components 702. The compaction inner diameter can be changed by the extension and retraction of the telescopic components 702. This can be adapted to the assembly process of different types of rubber tubes and steel flanges. Since the slide rail 601 is annular in the receiving area 6, the bottom of the slider 701 and the connection of the slide rail 601 should be arc-shaped to facilitate the sliding of the two. When the compaction roller 703 extends and retracts with the telescopic components 702, it should avoid touching the inner wall of the receiving area 6 to prevent damage to the inner wall of the receiving area 6 during the compaction process.

[0053] Specifically, the telescopic support assembly 10 includes a piston rod 1001, and a plurality of expansion rods 1002 are provided on the outer surface of the piston rod 1001. The plurality of expansion rods 1002 surround the outer surface of the piston rod 1001, and a plurality of support rods 1003 corresponding to the plurality of expansion rods 1002 are also provided on the piston rod 1001.

[0054] The telescopic support assembly 10 in the flange support device mainly relies on the piston action of the piston rod 1001 to push the support rod 1003 set on the outer surface of the piston rod 1001 to expand and contract. At the same time, the support rod 1003 drives the expansion rod 1002 to expand and contract. When the piston rod 1001 extends into the steel flange 9, the piston rod 1001 is activated, causing the expansion rod 1002 to expand until multiple expansion rods 1002 press against the inner wall of the steel flange 9, thus completing the support and fixation of the steel flange 9.

[0055] Specifically, each of the front ends of the plurality of expansion rods 1002 and the plurality of support rods 1003 is provided with rollers 1005. The rollers 1005 on the plurality of support rods 1003 act on the bottom of the plurality of expansion rods 1002. The plurality of support rods 1003 are installed in the mounting grooves 1004 provided on the outer surface of the piston rod 1001 and are located below the front ends of the plurality of expansion rods 1002.

[0056] The rollers 1005 located at the front end of the multiple expansion rods 1002 are mainly used to compress the inner wall of the steel flange 9. The rollers 1005 located at the front end of the multiple support rods 1003 mainly act on the expansion rods 1002 and expand them. The support rods 1003 are located in the mounting grooves 1004 on the piston rod 1001, so they do not occupy extra space during operation, allowing the expansion rods 1002 to maintain their initial position for expansion and contraction.

[0057] Specifically, the tail ends of the multiple expansion rods 1002 are provided with through holes 1006, and the multiple through holes 1006 are connected in series by a fixing ring 1007. A perforated ring 1008 is provided above the tail ends of the multiple expansion rods 1002, and a spring rod 1009 is connected in series between the multiple perforated rings 1008.

[0058] During operation, as the expansion rod 1002 expands outward, the perforated ring 1008 is connected in series at the tail of the multiple expansion rods 1002. When the rod expands as a whole, it rotates around the perforated ring 1008 to achieve expansion at one end. The spring rod 1009 connected in series above the expansion rod 1002 facilitates the rebound of the expansion rod 1002, making the rebound process more effortless, reducing friction between the expansion rod 1002 and the support rod 1003, and extending the service life of the device.

[0059] Specifically, the bottom of the movable arm 8 is provided with a rotating shaft 801, which is installed in a groove 101 on one side of the top of the operating table 1. The groove 101 is located in the middle of the intersection of the top and side of the operating table 1.

[0060] In this invention, the movable arm 8 in the flange support device can rotate around the rotating shaft 801. The rotating shaft 801 is installed in the groove 101 set on the top of the operating table 1, so that the whole device can rotate with the movable arm 8, which makes it easier to place the steel flange 9 before the assembly process begins, and makes the operation simpler and less strenuous for the staff.

[0061] Specifically, the bottom of the operating table 1 is provided with a receiving box 11, the side of the receiving box 11 is provided with a protective net 1101, the receiving box 11 is provided with multiple servo motors 12, and the bottom of the operating table 1 is also provided with a rotating motor 13 near the flange support device.

[0062] Specifically, the rotation diameter of the compaction component 7 in the receiving area 6 should be at least greater than the cross-sectional diameter of the telescopic rod 302 and the minimum expansion diameter of the telescopic support component 10.

[0063] In this invention, the bottom of the operating table 1 is provided with a housing 11 for placing the servo motor 12, which centrally installs the servo motor 12, saving installation space. Moreover, the installation at the bottom of the operating table 1 avoids damage to the motor during assembly and affects assembly efficiency. The side of the housing 11 is also provided with a protective net 1101, which not only avoids damage to the servo motor 12 by external force, but also provides good heat dissipation and maintains a good working environment for the servo motor 12.

[0064] The minimum compaction range of the compaction component 7 in the receiving area 6 should be at least larger than the minimum support surface of the telescopic rod 302; otherwise, the rubber tube 2 cannot be inserted into the receiving area 6. Similarly, the minimum support diameter of the telescopic support component 10 is also smaller than the minimum compaction diameter of the compaction component 7, which facilitates the assembly between the rubber tube 2 and the steel flange 9.

[0065] An assembly process for rubber hoses and steel flanges includes the following steps:

[0066] S1. Place the rubber tube 2 on the two sets of rotating rollers 402 in the rubber tube support assembly 4, and at the same time start the telescopic base 401 to move the rubber tube 2 to the position corresponding to the rubber tube positioning assembly 3.

[0067] S2. Activate the rubber tube positioning assembly 3 so that the telescopic rod 302 extends into the rubber tube 2. When the telescopic rod 302 extends to the designated position, activate the telescopic fixing block 303 so that it squeezes and fixes the rubber tube 2 from the inside.

[0068] S3. Place the metal sleeve on the compaction end of the rubber tube 2 and place it on the compaction path of the compaction component 7 within the receiving area 6.

[0069] S4. Place the steel flange 9 onto the telescopic support assembly 10 in the flange support device, start the rotating motor 13 to make the piston rod 1001 extend and retract, driving the support rod 1003 to lift the expansion rod 1002 to fix the steel flange 9.

[0070] S5. Start the movable arm 8 in the flange support device, rotate it to drive the steel flange 9 to align with the receiving area 6, and place the tube part of the steel flange 9 into the rubber tube 2.

[0071] S6. Adjust the telescopic component 702 in the compaction assembly 7 so that the compaction roller 703 can press the metal sleeve onto the rubber tube 2 and the steel flange 9.

[0072] S7. Start the slider 701 in the compaction assembly 7 so that it can move in the slide rail 601, driving the compaction roller 703 to repeatedly press the metal sleeve onto the rubber tube 2 and the steel flange 9 until it is completely compacted.

[0073] S8. Remove the compressed rubber hose and steel flange, and conduct an airtightness check. After ensuring there is no leakage, complete the acceptance.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
