Description

Technical Field

[0001] The invention relates to the field of steel pipe straightening, in particular to stainless steel pipe forming equipment with a straightening mechanism. Background Art

[0002] In the production process of stainless steel pipes, after rolling, welding and other processes, the steel pipes often bend and deform. Some existing steel pipe forming equipment either lacks a special straightening mechanism, which makes the straightness of the produced steel pipes substandard, affecting subsequent use. For example, in fields such as building structure construction and precision instrument installation that require high straightness of steel pipes, bent steel pipes cannot meet the installation accuracy requirements, reducing product quality and increasing production costs.

[0003] In order to ensure the safety and reliability of steel pipes during use, the bent steel pipes need to be straightened. During straightening, the bending position is usually squeezed to make the stainless steel pipe straight. However, since the inside of the steel pipe is hollow, it is easy to squeeze the steel pipe into a dent when squeezing it, which affects the strength and normal use of the steel pipe.

[0004] Therefore, in view of the above technical problems, it is necessary to propose a stainless steel pipe forming equipment with a straightening mechanism. Summary of the invention

[0005] In order to make up for the shortcomings of the prior art, the interior of the steel pipe is hollow, which makes it easy to squeeze the steel pipe into a dent when extruding it, affecting the strength and normal use of the steel pipe. The present invention proposes a stainless steel pipe forming equipment with a straightening mechanism.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A stainless steel pipe forming device with a straightening mechanism comprises a workbench, an anti-extrusion column is arranged on the top of the workbench, a stainless steel pipe is sleeved on the surface of the anti-extrusion column, and a straightening mechanism is arranged on the top of the workbench;

[0008] The straightening mechanism includes a first hollow block, the bottom of the first hollow block is fixedly connected to the top of the workbench, the inner cavity of the first hollow block is rotatably connected to a threaded rod, the surface of the threaded rod is threadedly connected to a sleeve, the surface of the sleeve is provided with a limiting groove, the inner cavity of the limiting groove is slidably connected to the limiting block, the bottom of the limiting block is fixedly connected to the top of the workbench, the top of the workbench is fixedly connected to a second hollow block, the inner cavity of the second hollow block is rotatably connected to a connecting rod, one end of the connecting rod is fixedly connected to an incomplete gear, the top of the workbench is fixedly connected to a third hollow block, the inner cavity of the third hollow block is slidably connected to a rack, one side of the rack is fixedly connected to one end of the anti-extrusion column, the teeth of the rack are meshed with the teeth of the incomplete gear, and the surfaces of the threaded rod and the connecting rod are sleeved with belts.

[0009] A support plate is fixedly connected to one side of the workbench, a motor is fixedly connected to the top of the support plate, and an output shaft surface of the motor is fixedly connected to one end of the threaded rod.

[0010] The surface of the stainless steel pipe is provided with a baffle and a fixing plate, and the bottoms of the baffle and the fixing plate are both fixedly connected to the top of the workbench.

[0011] A rubber block is arranged on one side of the stainless steel pipe, and one side of the rubber block is fixedly connected to one end of the sleeve.

[0012] The bottom of the rack is slidably connected with a moving rail, and the moving rail is fixedly connected to one side of the workbench through a fixing rod.

[0013] One end of the connecting rod is fixedly connected with a fixing block, and the diameter of the fixing block is greater than the diameter of the connecting rod.

[0014] An annular block is arranged on one side of the second hollow block, and the inner cavity of the annular block is fixedly connected to the surface of the connecting rod.

[0015] Both sides of the rack are provided with scales.

[0016] Reinforcing ribs are arranged between the baffle plate, the fixing plate and the workbench.

[0017] Beneficial effects of the present invention: the present invention drives the sleeve to move through the threaded rod to squeeze the curved part of the stainless steel pipe, thereby achieving the straightening effect. At the same time, the threaded rod will also drive the connecting rod and the incomplete gear to rotate together through the belt, and then the incomplete gear will drive the rack and the anti-extrusion column to move. At this time, the anti-extrusion column will move inside the stainless steel pipe, so that when the sleeve is straightening the stainless steel pipe, the anti-extrusion column can move inside the stainless steel pipe, achieving the effect of filling the internal space of the stainless steel pipe. Even if the sleeve squeezes the stainless steel pipe to make it straight, the anti-extrusion column inside the stainless steel pipe will not be able to squeeze the stainless steel pipe into a depression, thereby not affecting the strength of the stainless steel pipe and the effect of normal use. The problem that the interior of the stainless steel pipe is hollow, resulting in the stainless steel pipe being easily squeezed into a depression when the stainless steel pipe is squeezed, affecting the strength and normal use of the stainless steel pipe is solved.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0029] The following is combined with Figure 1-6 To further explain this application in detail,

[0030] A stainless steel pipe forming device with a straightening mechanism comprises a workbench 1, an anti-squeezing column 2 is arranged on the top of the workbench 1, a stainless steel pipe 3 is sleeved on the surface of the anti-squeezing column 2, and a straightening mechanism 4 is arranged on the top of the workbench 1. The anti-squeezing column 2 and the stainless steel pipe 3 can be placed on the upper side of the workbench 1, and the stainless steel pipe 3 can be sleeved on the outer side of the anti-squeezing column 2. At this time, the anti-squeezing column 2 can not only fix the stainless steel pipe 3 so that the stainless steel pipe 3 can be stably on the top of the workbench 1, but the anti-squeezing column 2 can also be driven by the straightening mechanism 4 to move inside the stainless steel pipe 3. The straightening mechanism 4 can straighten the stainless steel pipe 3 so that the stainless steel pipe 3 can be straightened and is not prone to dents.

[0031] The straightening mechanism 4 includes a first hollow block 401, the bottom of the first hollow block 401 is fixedly connected to the top of the workbench 1, the inner cavity of the first hollow block 401 is rotatably connected to a threaded rod 402, the surface of the threaded rod 402 is threadedly connected to a sleeve 403, the surface of the sleeve 403 is provided with a limiting groove 404, the inner cavity of the limiting groove 404 is slidably connected to a limiting block 405, the bottom of the limiting block 405 is fixedly connected to the top of the workbench 1, and the top of the workbench 1 is fixedly connected to a second hollow block 4 06, the inner cavity of the second hollow block 406 is rotatably connected with a connecting rod 407, one end of the connecting rod 407 is fixedly connected with an incomplete gear 410, the top of the workbench 1 is fixedly connected with a third hollow block 408, the inner cavity of the third hollow block 408 is slidably connected with a rack 409, one side of the rack 409 is fixedly connected to one end of the anti-extrusion column 2, the teeth of the rack 409 are meshed with the teeth of the incomplete gear 410, and the surfaces of the threaded rod 402 and the connecting rod 407 are covered with a belt 411,

[0032] The interior of the first hollow block 401 can be used to support the threaded rod 402, so that the threaded rod 402 can be stably rotated on the top of the workbench 1, and the threaded rod 402 can drive the sleeve 403 to move when rotating. The sleeve 403 is located on one side of the stainless steel pipe 3 and can squeeze the curved part of the stainless steel pipe 3 by moving, so as to achieve the effect of straightening the stainless steel pipe 3. The interior of the limiting groove 404 can be used to place the limiting block 405, so that when the threaded rod 402 rotates, the sleeve 403 can be driven to move. The third hollow block 408 can be limited by the limit block 405, which allows the sleeve 403 to move smoothly and is not easy to rotate together. The interior of the third hollow block 408 can be used to place the rack 409, so that the rack 409 can be stabilized on the upper side of the workbench 1 and move, and the rack 409 can be connected to the anti-extrusion column 2 to fix the anti-extrusion column 2, so that the anti-extrusion column 2 can also be stabilized on the upper side of the workbench 1 and can be driven by the rack 409 to move together. The second hollow block 406 can support the connecting rod 407. The belt 411 is connected to the surface of the threaded rod 402 and the connecting rod 407, so that when the threaded rod 402 rotates and drives the sleeve 403 to move to straighten the stainless steel pipe 3, it will simultaneously drive the connecting rod 407 and the rack 409 to rotate, thereby allowing the incomplete gear 410 and the anti-extrusion column 2 to move inside the stainless steel pipe 3. At this time, the anti-extrusion column 2 can fill the inside of the stainless steel pipe 3, so that even if the sleeve 403 squeezes the stainless steel pipe 3 to straighten it, the stainless steel pipe 3 cannot be squeezed out of a depression due to the anti-extrusion column 2 inside the stainless steel pipe 3, thereby not affecting the strength and normal use of the stainless steel pipe 3. In addition, the surface of the incomplete gear 410 has fewer teeth, so that after the threaded rod 402 rotates one circle, the incomplete gear 410 will not drive the rack 409 and the anti-extrusion column 2 to move too far.

[0033] A support plate 5 is fixedly connected to one side of the workbench 1, and a motor 6 is fixedly connected to the top of the support plate 5. The output shaft surface of the motor 6 is fixedly connected to one end of the threaded rod 402. The support plate 5 is set up to support the motor 6 so that the motor 6 can be stabilized on one side of the threaded rod 402, and the motor 6 can drive the threaded rod 402 to rotate, which makes the rotation of the threaded rod 402 more convenient, and people do not need to manually rotate the threaded rod 402, reducing people's fatigue.

[0034] The surface of the stainless steel pipe 3 is provided with a baffle 7 and a fixing plate 12, and the bottoms of the baffle 7 and the fixing plate 12 are fixedly connected to the top of the workbench 1. The baffle 7 and the fixing plate 12 can shield and fix the stainless steel pipe 3, so that the stainless steel pipe 3 can be more stable and less likely to warp when it is squeezed and straightened by the sleeve 403, and at the same time, the rack 409 is less likely to be broken and damaged inside the third hollow block 408.

[0035] A rubber block 8 is provided on one side of the stainless steel pipe 3. One side of the rubber block 8 is fixedly connected to one end of the sleeve 403. The rubber block 8 has a large friction force and can be deformed. When the sleeve 403 is squeezed into the stainless steel pipe 3 for straightening, the rubber block 8 can not only increase the contact area but also play an anti-slip role, so that the sleeve 403 can extrude the stainless steel pipe 3 more smoothly and stably.

[0036] The bottom of the rack 409 is slidably connected to a movable rail 13, and the movable rail 13 is fixedly connected to one side of the workbench 1 through a fixed rod 9. The fixed rod 9 can support the bottom of the rack 409 and the movable rail 13, so that the rack 409 on one side of the workbench 1 is not easy to break due to being too long and pressed.

[0037] One end of the connecting rod 407 is fixedly connected to a fixing block 10, the diameter of the fixing block 10 is larger than the diameter of the connecting rod 407, and the fixing block 10 can limit the belt 411, so that the belt 411 is more stable on the surface of the connecting rod 407 and is not easy to separate from the connecting rod 407.

[0038] An annular block 11 is arranged on one side of the second hollow block 406, and the inner cavity of the annular block 11 is fixedly connected to the surface of the connecting rod 407. Two annular blocks 11 are arranged, which are respectively located on both sides of the second hollow block 406, and the connecting rod 407 can be limited so that the connecting rod 407 and the incomplete gear 410 are not easy to move, thereby effectively ensuring the stability of the connecting rod 407 and the incomplete gear 410.

[0039] Scales 412 are provided on both sides of the rack 409 .

[0040] Reinforcing ribs 14 are provided between the baffle plate 7 and the fixing plate 12 and the workbench 1 , and the reinforcing ribs 14 increase the connection strength between the baffle plate 7 and the fixing plate 12 and the workbench 1 .

[0041] Working principle:

[0042] When using the device, the stainless steel pipe 3 to be straightened is sleeved on the surface of the anti-extrusion column 2, and then the motor 6 is started to drive the threaded rod 402 to rotate, and the threaded rod 402 will drive the sleeve 403 to move, and at the same time, the sleeve 403 will move on the surface of the limit block 405 through the limit groove 404. When the sleeve 403 moves, it will squeeze the curved part of the stainless steel pipe 3, so as to achieve the straightening effect, and when the threaded rod 402 rotates, it will also drive the connecting rod 407 to rotate through the belt 411, and the connecting rod 407 will drive the incomplete gear 410 to rotate together, and then the incomplete gear 410 will drive the rack 409 and the anti-extrusion column 2 to move, and at this time the anti-extrusion column 2 will move on the stainless steel pipe 3. The anti-extrusion column 2 can move inside the stainless steel pipe 3 when the sleeve 403 is straightening the stainless steel pipe 3, thereby achieving the effect of filling the internal space of the stainless steel pipe 3. Even if the sleeve 403 squeezes the stainless steel pipe 3 to make it straight, the anti-extrusion column 2 inside the stainless steel pipe 3 cannot squeeze the stainless steel pipe 3 into a dent, thereby not affecting the strength and normal use of the stainless steel pipe 3. The problem that the interior of the stainless steel pipe 3 is hollow, which makes it easy to squeeze the stainless steel pipe 3 into a dent when squeezing the stainless steel pipe 3, thus affecting the strength and normal use of the stainless steel pipe 3 can be solved.
