Description

Technical Field

[0001] This utility model belongs to the field of stainless steel pipe bending technology, specifically relating to a grooved anti-crack stainless steel pipe bending device. Background Technology

[0002] Stainless steel pipes are widely used in construction, chemical, automotive, and furniture manufacturing industries due to their excellent corrosion resistance and mechanical properties. In practical applications, stainless steel pipes often need to be bent into various shapes. However, because stainless steel has high hardness and relatively low ductility, its outer wall surface is prone to cracking due to excessive tensile stress when bent at large angles or small radii, severely affecting product quality and structural strength. Therefore, grooves are often cut into the pipe wall before bending.

[0003] Problems with existing technology: Currently available slotted anti-crack stainless steel pipes are prone to deformation during bending due to the slots on their surface. This can lead to cracking on the outer side and wrinkling on the inner side, thus affecting the yield of the bent stainless steel pipes. Utility Model Content

[0004] The purpose of this invention is to provide a slotted, crack-resistant stainless steel pipe bending device that can provide effective support from the inside when bending the stainless steel pipe through an internal flexible support mechanism that is slidably installed on the top of the frame via a guide rail, and through a dynamically changeable flexible bladder, while preventing cracking on the outside and wrinkling on the inside.

[0005] The specific technical solution adopted by this utility model is as follows: A slotted, crack-resistant stainless steel pipe bending device, comprising a frame; An internal flexible support mechanism is slidably mounted on the top of the frame via guide rails, and a bending mechanism is fixedly mounted on one end of the frame; The internal flexible support mechanism includes a drive assembly fixedly installed at the other end of the frame. The drive assembly is used to drive the support assembly to move linearly, so that one end of the support assembly passes through the interior of the bend in the stainless steel pipe, and one end of the support assembly abuts against the inner wall of the stainless steel pipe.

[0006] The drive assembly includes a motor fixedly mounted on one end of the guide rail. The motor is used to drive the lead screw to rotate. The lead screw is threadedly mounted to the slide table via a connecting sleeve.

[0007] The connecting sleeve is fixedly installed at the bottom of the slide table, and the bottom of the connecting sleeve is slidably installed with the frame via a guide rail.

[0008] A support assembly is fixedly installed on the top of the slide, so that the slide drives the support assembly to move linearly on the top of the frame.

[0009] The support assembly includes a mounting base fixedly installed on the top of the slide table. A fluid tank and a hollow rod are fixedly installed on both sides of the mounting base, and the fluid tank is connected to the hollow rod through the mounting base.

[0010] A pump body is fixedly installed on one side of the fluid tank, and the other end of the hollow rod is connected to the flexible bladder.

[0011] The bending mechanism includes a fixed platform fixedly installed at one end of the frame. A limit component and a bending component are fixedly installed on the top of the fixed platform. The bending component is used to push the stainless steel pipe to move.

[0012] The technical effects achieved by this utility model are as follows: This invention utilizes a guide rail fixedly installed on the top of the frame and a lead screw rotatably installed. By driving the lead screw to rotate via a motor, the connecting sleeve can move linearly through the slide table, thereby causing the hollow rod of the support component to move into the bending part. Furthermore, the other end of the hollow rod is threaded to the mounting base, allowing for convenient disassembly and replacement according to the different lengths of the stainless steel pipe during use.

[0013] This invention utilizes a fluid tank installed on one side of a mounting base, with hydraulic oil inside. A pump on one side of the fluid tank delivers the hydraulic oil through the mounting base and a hollow rod into a flexible bladder. This causes the flexible bladder to expand at the bending point, abutting against the inner wall of the stainless steel pipe and providing internal flexible support. This effectively prevents cracking on the outer side and wrinkling on the inner side of the bend, significantly improving processing quality and yield. Furthermore, the flexible bladder can perfectly fill the inner wall of pipes with different diameters and a certain degree of ellipticity under pressure, exhibiting excellent versatility. After depressurization, the flexible bladder contracts and separates from the pipe wall, resulting in low resistance when pulling the rod and easy operation. Attached Figure Description

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figure 1-4 As shown, a slotted, crack-resistant stainless steel pipe bending device includes a frame 1; An internal flexible support mechanism 3 is slidably installed on the top of the frame 1 via a guide rail 2, and a bending mechanism 4 is fixedly installed at one end of the frame 1; The internal flexible support mechanism 3 includes a drive assembly 31 fixedly installed at the other end of the frame 1. The drive assembly 31 is used to drive the support assembly 32 to move linearly, so that one end of the support assembly 32 passes into the interior of the stainless steel pipe bend, and one end of the support assembly 32 abuts against the inner wall of the stainless steel pipe.

[0018] See attached document Figure 1 , Figure 2 and Figure 3 In this embodiment, the drive assembly 31 includes a motor 311 fixedly installed at one end of the guide rail 2. The motor 311 is used to drive the lead screw 312 to rotate. The lead screw 312 is threadedly installed to the slide table 313 through a connecting sleeve 314.

[0019] In the above embodiment, since the connecting sleeve 314 is fixedly installed at the bottom of the slide table 313 and the connecting sleeve 314 is threadedly installed with the lead screw 312, when the starting motor 311 drives the lead screw 312 to rotate, the bottom of the connecting sleeve 314 can slide linearly on the top of the frame 1 through the guide rail 2.

[0020] Furthermore, since the support assembly 32 is fixedly installed on the top of the slide table 313, the slide table 313 can drive the support assembly 32 to move linearly on the top of the frame 1 during the rotation of the lead screw 312.

[0021] See attached document Figure 2 , Figure 3 and Figure 4Specifically, the support assembly 32 includes a mounting base 321 fixedly installed on the top of the slide table 313. A fluid tank 323 and a hollow rod 324 are fixedly installed on both sides of the mounting base 321, respectively. The fluid tank 323 is connected to the hollow rod 324 through the mounting base 321. The mounting base 321 has a hollow structure, and the hollow rod 324 is threaded onto one end of the mounting base 321. The fluid tank 323 is filled with hydraulic oil.

[0022] More specifically, a pump body 322 is fixedly installed on one side of the fluid tank 323, and the outlet of the pump body 322 is connected to the internal flow channel of the mounting base 321, so that the hydraulic oil can enter the flow channel of the hollow rod 324. At the same time, since the other end of the hollow rod 324 is connected to the flexible bladder 325, the hydraulic oil can enter the interior of the flexible bladder 325 and push the outer wall of the flexible bladder 325 to expand.

[0023] It should be noted that the activation of the drive component 31 can drive the support component 32 and the flexible bladder 325 to penetrate into the bend of the slotted crack-resistant stainless steel pipe, and the activation of the pump body 322 can provide flexible support to the inside of the bend, thereby preventing cracking on the outside and wrinkling on the inside during the bending process of the stainless steel pipe by the bending mechanism 4.

[0024] According to the above structure, the bending mechanism 4 includes a fixed platform 41 fixedly installed at one end of the frame 1. A limiting component 42 and a bending component 43 are fixedly installed on the top of the fixed platform 41. The limiting component 42 is used to limit the movement of stainless steel pipes of different diameters, while the bending component 43 is used to push the stainless steel pipe to move and realize the bending process of the stainless steel pipe.

[0025] The working principle of this utility model is as follows: After one end of the stainless steel pipe is passed through the limiting component 42 and sent into the interior of the bending component 43 to the set position, the stainless steel pipe can be clamped and limited by adjusting the limiting component 42 and the fixing table 41. Then, the starting motor 311 drives the lead screw 312 to rotate, so that the connecting sleeve 314 drives the support component 32 to move linearly through the slide table 313. In turn, the support component 32 drives the flexible bladder 325 to penetrate into the interior of the stainless steel pipe through the hollow rod 324. The flexible bladder 325 moves to the bending point. At the same time, the pump body 322 is started to send the hydraulic oil in the fluid tank 323 into the interior of the flexible bladder 325 through the mounting seat 321 and the hollow rod 324. Through the expansion of the flexible bladder 325, flexible support can be provided for the inner wall of the stainless steel pipe, avoiding cracking on the outside and wrinkling on the inside of the stainless steel pipe during the bending process.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
