Description

Technical Field

[0001] This utility model belongs to the field of pipe processing technology, specifically a device for pipe end flanging processing. Background Technology

[0002] Pipe end flanging is a process of bending or expanding the end of a pipe to form an edge, mainly used for connection, sealing, reinforcement and improvement of safety. Through methods such as rolling, stamping, hot flanging or bulging, different shapes such as external flanging, internal flanging, flat flanging or conical flanging can be formed at the pipe end. The choice of flanging process depends on the pipe material, size and required performance. Flanging can effectively improve the reliability of pipe connection, provide better sealing effect and enhance the structural strength of pipe end, and is an important part of pipe system connection.

[0003] Currently, when performing tapered flanging on the ends of pipes, the pipes need to be fixed first, and then the flanging equipment is used for processing. Fixing the pipes and flanging are two separate steps. This processing operation reduces the integration and performance of the equipment, increases the number of processing steps, and reduces the processing efficiency. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for flange processing of pipe ends, comprising a fixed base, a placement base fixedly installed on the top of the fixed base, a height-adjustable clamping block installed on the top of the placement base, a metal pipe body clamped and fixed between the top of the placement base and the bottom of the clamping block, a horizontally adjustable push plate installed on the top of the fixed base, the push plate being connected to the clamping block and adjusting the height of the clamping block, a hydraulic telescopic cylinder connected to the push plate being provided on the top of the fixed base, a forward and reverse motor installed on the upper part of one side of the push plate, and a rotating shaft rotatably installed on the upper part of the other side of the push plate, connected to the output end of the forward and reverse motor, with a conical flange block coaxial with the metal pipe body installed at one end of the rotating shaft.

[0005] Preferably, the top of the placement base and the bottom of the clamping block are symmetrically provided with V-shaped placement grooves, and the inside of each V-shaped placement groove is equipped with a rubber pad layer for clamping and preventing slippage of the metal pipe body.

[0006] Preferably, two T-shaped fixing rods are fixedly installed on both sides of the clamping block, and two fixing sleeves aligned vertically with the T-shaped fixing rods are fixedly installed on the upper part of both sides of the base. The T-shaped fixing rods are movably inserted into the inside of the fixing sleeves. An adjusting plate is fixedly installed between the bottoms of the two T-shaped fixing rods on the same side. An adjusting groove is opened on the opposite side of the two adjusting plates. The adjusting groove is composed of a horizontal groove and an oblique groove.

[0007] Preferably, a vertical plate and a fixed block are fixedly installed on the top of the fixed base, and two sliding rods are fixedly installed between the lower parts of the vertical plate and the fixed block. A hydraulic telescopic cylinder is installed on the top of the fixed block, and the lower part of the push plate is slidably sleeved between the two sliding rods. Two adjusting rods are symmetrically and movably installed through the upper part of the vertical plate. One end of each adjusting rod is fixedly connected to the push plate, and the other end of each adjusting rod is equipped with a pressing adjusting metal wheel located inside the adjusting groove.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This flanging processing device has a clamping and fixing and flanging processing linkage transmission adjustment function, which can clamp and fix the pipe before flanging the pipe during processing, thereby effectively improving the integration of the equipment, reducing the processing steps and improving the processing efficiency. When in use, the squeezing adjustment metal wheel is located at the bottom of the inclined groove on the adjustment groove, while the clamping block is located directly above the placement base. At the same time, the distance between the clamping block and the placement base is sufficient for the installation and removal of the metal pipe body. Then, the metal pipe body is placed inside the V-shaped placement groove at the top of the placement base. Next, the hydraulic telescopic cylinder is activated to extend and push the push plate to slide on the two slide rods. The movement of the push plate will drive the forward and reverse motor, the rotating shaft and the conical flange block to move towards the processed end of the metal pipe body. At the same time, the movement of the push plate will push the two adjusting rods and the two extrusion adjusting metal wheels to move. The two extrusion adjusting metal wheels will move upward at the bottom of the inclined groove on the two adjusting grooves. At the same time, the upward movement of the extrusion adjusting metal wheels will extrude the inclined groove, thereby causing the two adjusting plates to drive the clamping block to move downward through the two T-shaped fixing rods. The clamping block cooperates with the placement base through the V-shaped placement groove to clamp and fix the metal pipe body. After the extrusion adjusting metal wheel moves from the inside of the inclined groove on the adjusting groove to the inside of the horizontal groove, the clamping block and the placement base cooperate to firmly clamp and fix the metal pipe body. At the same time, the clamping block stops moving down, and the conical flange block is inserted into the processing end of the metal pipe body. Then, the extrusion adjusting metal wheel continues to move inside the horizontal groove, while the forward and reverse motor is turned on, so that the rotating shaft drives the conical flange block to rotate. The moving and rotating conical flange block can effectively perform conical flange processing on the end of the metal pipe body. Attached Figure Description

Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0012] Depend on Figure 1 and Figure 2 The present invention includes a fixed base 1, a placement base 2 fixedly installed on the top of the fixed base 1, an adjustable clamping block 3 installed on the top of the placement base 2, a metal pipe body 4 clamped and fixed between the top of the placement base 2 and the bottom of the clamping block 3, and V-shaped placement grooves symmetrically opened on the top of the placement base 2 and the bottom of the clamping block 3, and rubber pads for clamping and preventing slippage of the metal pipe body 4 are installed inside the V-shaped placement grooves.

[0013] A horizontally adjustable push plate 5 is installed on the top of the fixed base 1. The push plate 5 is connected to the clamping block 3 and adjusts the clamping block 3 by raising and lowering. A hydraulic telescopic cylinder 6 connected to the push plate 5 is provided on the top of the fixed base 1. A forward and reverse motor 7 is installed on the upper part of one side of the push plate 5. A rotating shaft 8 connected to the output end of the forward and reverse motor 7 is rotatably installed on the upper part of the other side of the push plate 5. A conical flange block 9 coaxial with the metal pipe body 4 is installed at one end of the rotating shaft 8. The conical flange block 9 is installed on the rotating shaft 8 by bolts. Different conical flange blocks 9 can be replaced according to different needs of pipe flange processing.

[0014] When flanging pipes made of low-hardness or low-strength materials, heating the pipe ends is not required. Pipes made of low-hardness or low-strength materials have good ductility and can be flanged at room temperature using the conical flanging block 9. Similarly, when flanging small or thin-walled pipes, the flanging deformation is small, and the flanging operation can also be performed at room temperature using the conical flanging block 9. When flanging high-hardness, high-strength, large, or thick-walled pipes, the pipe ends can be heated using an electromagnetic heating coil before the flanging operation is performed using the conical flanging block 9.

[0015] Two T-shaped fixing rods 301 are fixedly installed on both sides of the clamping block 3. Two fixing sleeves 10, which are aligned vertically with the T-shaped fixing rods 301, are fixedly installed on the upper part of both sides of the base 2. The T-shaped fixing rods 301 are movably inserted into the inside of the fixing sleeves 10. An adjusting plate 11 is fixedly installed between the bottoms of the two T-shaped fixing rods 301 on the same side. An adjusting groove 12 is opened on the opposite side of the two adjusting plates 11. The adjusting groove 12 is composed of a horizontal groove and an oblique groove.

[0016] A vertical plate 13 and a fixing block 14 are fixedly installed on the top of the fixed base 1. Two sliding rods 15 are fixedly installed between the lower parts of the vertical plate 13 and the fixing block 14. A hydraulic telescopic cylinder 6 is installed on the top of the fixing block 14. The lower part of the push plate 5 is slidably sleeved between the two sliding rods 15. Two adjusting rods 16 are symmetrically and movably installed through the upper part of the vertical plate 13. One end of each adjusting rod 16 is fixedly connected to the push plate 5, and the other end of each adjusting rod 16 is equipped with a pressing adjusting metal wheel 17 located inside the adjusting groove 12, so as to effectively perform fixing and flanging operations.

[0017] Specifically, in use, the extrusion adjustment metal wheel 17 is located at the bottom of the inclined groove on the adjustment groove 12, while the clamping block 3 is located directly above the placement base 2. At the same time, the distance between the clamping block 3 and the placement base 2 is sufficient for the installation and removal of the metal pipe body 4. Then, the metal pipe body 4 is placed inside the V-shaped placement groove at the top of the placement base 2. Next, the hydraulic telescopic cylinder 6 is activated to extend and push the push plate 5 to slide on the two slide rods 15. The movement of the push plate 5 will drive the forward and reverse motor 7, the rotating shaft 8 and the conical flange block 9 to move towards the processing end of the metal pipe body 4. At the same time, the movement of the push plate 5 will push the two adjusting rods 16 and the two extrusion adjusting metal wheels 17 to move, so that the two extrusion adjusting metal wheels 17 move upward at the bottom of the inclined groove on the two adjusting curved grooves 12. At the same time, the upward movement of the extrusion adjusting metal wheels 17 will extrude the inclined groove, so that the two adjusting plates 11 drive the clamping block 3 to move downward through the two T-shaped fixing rods 301. The clamping block 3 cooperates with the placement base 2 through the V-shaped placement groove to clamp and fix the metal pipe body 4. When the extrusion adjusting metal wheel 17 moves from the inside of the inclined groove on the adjusting groove 12 to the inside of the horizontal groove, the clamping block 3 and the placement base 2 cooperate to firmly clamp and fix the metal pipe body 4. At the same time, the clamping block 3 no longer moves down, and the conical flange block 9 is inserted into the processing end of the metal pipe body 4. Then, the extrusion adjusting metal wheel 17 continues to move inside the horizontal groove, and at the same time, the forward and reverse motor 7 is turned on, so that the rotating shaft 8 drives the conical flange block 9 to rotate. The moving and rotating conical flange block 9 can effectively perform conical flange processing on the end of the metal pipe body 4.
