Description

A stainless steel pipe flanging processing equipment Technical Field

[0001] This utility model mainly relates to the field of stainless steel pipe flanging, specifically to a stainless steel pipe flanging processing equipment. Background Technology

[0002] Stainless steel pipes are due to their superior quality

[0003] Due to its corrosion resistance, high strength, and aesthetic appeal, stainless steel is widely used in petrochemical, food processing, medical device, building decoration, and automobile manufacturing industries. In piping systems, the flanging of stainless steel pipe ends is a key forming process. Its purpose is to create a flange at a specific angle at the pipe end through plastic deformation, facilitating subsequent flange connections, sealing, or assembly with other pipe fittings. Stainless steel pipe flanging is primarily achieved using mechanical spinning, hydraulic or pneumatic forming, and stamping die methods.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] However, when stainless steel pipes are directly flanged using the above methods, uneven stress on the stainless steel pipes can still cause them to crack, affecting their quality.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Summary of the Invention

[0009] 2. Technical Solution:

[0010] To achieve the above objectives, the technical solution provided by this utility model is as follows: a stainless steel pipe flanging processing equipment, including a stainless steel pipe heating and fixing structure, wherein a stainless steel pipe flanging structure is provided directly above the stainless steel pipe heating and fixing structure.

[0011] A stainless steel tube heating and fixing structure includes a placement tube, and an electromagnetic induction heater is installed inside the placement tube.

[0012] A stainless steel tube flange structure includes a servo motor, a drive motor, a lifting ring, and a sliding hole. The number of lifting rings is set to two, and a flange structure is provided between the two lifting rings. The number of flange structures is set to multiple, and the multiple flange structures are arranged in a ring array between the two lifting rings.

[0013] Furthermore, electric push rods are provided on both sides of the outer wall of the placement tube, a vertical ring is provided between the two electric push rods, a vertical rod is provided at the top of the vertical ring, and a U-shaped strip is provided at the top of the vertical rod.

[0014] Furthermore, the outer wall of the placement tube is provided with a side frame, one end of which is rotatably connected to a rotating bar. A planar spiral spring is provided between the rotating bar and the side frame. The rotating bar is slidably connected to a U-shaped bar. A bonding plate is provided at the top of the rotating bar. A support ring is provided at the top of the bonding plate. An anti-slip strip is provided on the inner side of the support ring.

[0015] Furthermore, both the servo motor and the drive motor are positioned directly above the stainless steel tube heating and fixing structure. The output end of the servo motor is equipped with a drive gear, and the bottom of the drive motor is equipped with a driven gear, which meshes with the drive gear.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0020] This invention uses an electromagnetic induction heater to heat the end of a stainless steel tube that needs to be flanged. The stainless steel tube then moves upward and contacts the unheated stainless steel tube through a support ring. The stainless steel tube enters the outer wall of the pressure plate, and the pressure plate moves outward to squeeze the stainless steel tube, so that the flanged position is directly in contact with the pressure ring and the support ring. After that, the pressure plate rotates to rotate and flange the heated stainless steel tube. Heating the stainless steel tube can improve its plasticity. Attached Figure Description

The servo motor 201 and drive motor 203 are both positioned directly above the stainless steel tube heating and fixing structure 1. A drive gear is provided at the output end of the servo motor 201. 202. A driven gear 204 is provided at the bottom of the drive motor 203, which meshes with the driving gear 202. A transmission screw 205 is provided at the output end of the drive motor 203, which passes through the driven gear 204. A guide bar 206 is provided at the bottom of the drive motor 203. The threads at both ends of the transmission screw 205 have opposite directions of rotation, and the threads at both ends of the transmission screw 205 cooperate with the threaded hole in the middle of the lifting ring 207. The sliding hole... 208 is slidably connected to guide bar 206. The flanged structure includes auxiliary bar 209, which is rotatably connected to the outer wall of lifting ring 207. A rotating ring 210 is rotatably connected between the two auxiliary bars 209. A pressure plate 211 is provided on the outer wall of the rotating ring 210, and a pressure ring 212 is provided on the top of the pressure plate 211. Then, the drive motor 203 is started, which drives the transmission screw 205 to rotate. The transmission screw 205 drives the two guide bars 206 to move inward simultaneously. The auxiliary bar 209 is pushed to rotate by the push bar 206. The auxiliary bar 209 pushes the rotating ring 210 to move outward. The rotating ring 210 drives the pressure plate 211 to fit and press against the inner wall of the heated stainless steel tube, so that one end of the stainless steel tube fits against the pressure ring 212 and the support ring 109. Then, the servo motor 201 is started. The servo motor 201 drives the drive gear 202 to rotate. The drive gear 202 drives the driven gear 204 to rotate, so that the driven gear 204 drives the pressure plate 211 to rotate as a whole, thereby flanging the stainless steel tube 360°.

[0032] Furthermore, the stainless steel tube heating and fixing structure 1 includes a placement tube 101, an electromagnetic induction heater is installed inside the placement tube 101, electric push rods 102 are installed on both sides of the outer wall of the placement tube 101, a vertical ring 103 is installed between the two electric push rods 102, a vertical rod 104 is installed at the top of the vertical ring 103, a U-shaped strip 105 is installed at the top of the vertical rod 104, a side frame 106 is installed on the outer wall of the placement tube 101, a rotating strip 107 is rotatably connected to one end of the side frame 106, a planar spiral spring is installed between the rotating strip 107 and the side frame 106, the rotating strip 107 is slidably connected to the U-shaped strip 105, a bonding plate 108 is installed at the top of the rotating strip 107, a support ring 109 is installed at the top of the bonding plate 108, and the inner side of the support ring 109...

The steel pipe enters through the placement tube 101 and is heated by the electromagnetic induction heater inside the placement tube 101, softening the stainless steel pipe. Then, the stainless steel pipe moves upward, activating the electric push rod 102. The electric push rod 102 drives the vertical ring 103 to move upward, and the vertical ring 103 drives the vertical rod 104 to move upward, causing the vertical rod 104 to push the U-shaped bar 105 to move upward. The U-shaped bar 105 pushes the rotating bar 107 to rotate. The bonding plate 108 at the top of the rotating bar 107 is in contact with the outer wall of the stainless steel pipe. After the top of the bonding plate 108 is in contact with the outer wall of the stainless steel pipe, it compresses the planar spiral spring provided between the rotating bar 107 and the bonding plate 108, causing the bonding plate 108 to rotate. The anti-slip strip 110 on the inner side of the bonding plate 108 is in contact with the outer wall of the stainless steel pipe, clamping the stainless steel pipe.
