Description

Technical Field

[0001] The present invention relates to the technical field of pipe bending machines, and particularly to a pipe bending machine for processing stainless steel pipe fittings. Background Technique

[0002] Stainless steel pipe fittings are divided into round, square, rectangular and special-shaped steel pipes according to the cross-sectional shape; they are divided into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes and composite steel pipes according to the material; they are divided into steel pipes for conveying pipelines, engineering structures, thermal equipment, petrochemical industry, mechanical manufacturing, geological drilling, high-pressure equipment, etc. When processing steel pipe fittings, it is necessary to bend the steel pipes, so a pipe bending machine for steel pipe processing is needed to make them into bent steel pipe fittings.

[0003] However, in an environment where the temperature decreases, the brittleness of the steel pipe fittings becomes stronger. If the pipe bending machine directly bends the steel pipe fittings, it is very easy to crack, and the bent steel pipe is prone to bending springback, that is, the bent steel pipe elastically returns in the direction opposite to the deformation direction, so that the deformation amount after the round pipe is bent does not meet the bending requirements, affecting the bending processing effect of the steel pipe.

Specific embodiments

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] In order to solve the problem that in an environment where the temperature drops, the brittleness of steel pipe fittings becomes stronger, and when the pipe bender directly bends the steel pipe fittings, cracking is extremely likely to occur, as Figures 1 - 4 shown, the following preferred technical solutions are provided:

[0040] Pipe bender for processing stainless steel pipe fittings, including an installation table 1, and a sliding table 2 arranged at the upper end of the installation table 1. A positioning assembly 3 is arranged at the upper end of the sliding table 2. A pipe bending assembly 4 is arranged on one side of the positioning assembly 3. The pipe bending assembly 4 includes a turntable main body 41 installed at the upper end of the installation table 1. A concave mounting seat 42 is arranged at the upper end of the turntable main body 41. An arc-shaped bending plate 43 is axially connected to the inner wall of the concave mounting seat 42. A receiving arc-shaped block 44 is slidably connected to the outer wall of the arc-shaped bending plate 43. The receiving arc-shaped block 44 is fixedly connected to the outer wall of the concave mounting seat 42. A connecting frame 45 is slidably connected to the inner wall of the receiving arc-shaped block 44. A power main body 46 is installed inside the connecting frame 45. An output end of the power main body 46 is provided with a connecting block 47. A top bending mechanism 48 is slidably arranged inside the inner wall of the connecting block 47.

[0041] The top bending mechanism 48 is connected to the output end of the power main body 46. One end of the connecting block 47 is provided with a mounting disc 49. A processing frame 410 is fixedly connected to the end of the mounting disc 49 away from the connecting block 47. A bending wheel 411 is rotatably connected to the inner wall of the processing frame 410. The top bending mechanism 48 includes a movable top block 481 slidably connected to the connecting block 47. One end of the movable top block 481 is fixedly connected to a preheating top block 482. A fixing disc 483 is installed at one end of the movable top block 481. A heating main body 484 is installed at one end of the fixing disc 483. The heating main body 484 is installed inside the inner wall of the movable top block 481.

[0042] One end of the heating main body 484 away from the fixing disc 483 is fixedly connected to a heating block 485. One end of the heating block 485 away from the heating main body 484 is provided with a heat discharge channel 486. One end of the heat discharge channel 486 communicates with an installation groove 487. The installation groove 487 is opened on the inner wall of the preheating top block 482. A connecting column 488 is fixedly connected to the bottom plate of the installation groove 487. One end of the connecting column 488 is fixedly connected to a heat conducting top plate 489.

[0043] Specifically, when bending a steel pipe fitting, the part of the steel pipe fitting to be bent is placed into the processing frame 410 and abuts against the bending wheel 411. The positioning assembly 3 is used to fix other parts to ensure stability during the bending operation. The bending angle is adjusted through the cooperation of the turntable main body 41 and the concave mounting seat 42. By starting the power main body 46, the top bending mechanism 48 is driven to gradually approach the processing frame 410, thereby bending the steel pipe fitting.

[0044] Before the top bending mechanism 48 bends the steel pipe fitting, the heating main body 484 is started so that the heating block 485 emits heat. The emitted heat will enter the installation groove 487 from the heat discharge channel 486. Most of the heat is absorbed by the heat conducting top plate 489. When the preheating top block 482 abuts against the steel pipe fitting to be bent, the part of the steel pipe fitting to be bent is preheated through the heat conducting top plate 489. This not only avoids cracking of the steel pipe fitting under pressure but also makes the bending efficiency higher.

[0045] In order to facilitate the adjustment of the bending position, Figure 5 As shown, the following preferred technical solutions are provided:

[0046] An electric motor 412 is provided at one end of the connecting block 47 away from the top bending mechanism 48, and a rotating rod 413 is installed at the output end of the motor 412. A first position control gear 414 is fixedly installed at one end of the rotating rod 413 away from the motor 412, and an arc-shaped rack 415 is meshedly connected to one side of the first position control gear 414. The arc-shaped rack 415 matches the shape of the receiving arc block 44 and is fixedly connected thereto.

[0047] Specifically, by starting the motor 412, the output end of the motor 412 drives the rotating rod 413 to rotate, and the rotating rod 413 drives the control gear 414 to rotate. When the first control gear 414 rotates, through cooperation with the arc rack 415, the first control gear 414 drives the connecting frame 45, the power body 46, the connecting block 47, the top bending mechanism 48, the mounting plate 49, the processing frame 410 and the bending wheel 411. At the same time, the arc bending plate 43 is used to perform an angle flip on the inner wall of the arc block 44, thereby facilitating the adjustment of the bending position.

[0048] In order to solve the problem of bending springback of steel pipe after bending, Figure 6 As shown, the following preferred technical solutions are provided:

[0049] The positioning assembly 3 includes a roller 31 slidably connected to the slide 2, a transverse adjustment platform assembly 32 is installed on the upper end of the roller 31, a transverse clamping assembly 33 is installed on the upper end of the adjustment platform assembly 32, and a longitudinal clamping assembly 34 is installed on the connecting plate on one side of the adjustment platform assembly 32.

[0050] Specifically, the roller 31 can drive the adjusting table assembly 32 to move longitudinally on the slide 2, so as to achieve the purpose of longitudinal movement adjustment of the transverse clamping assembly 33 and the longitudinal clamping assembly 34. The transverse clamping assembly 33 can be driven by the adjusting table assembly 32 to perform transverse movement adjustment. When performing bending work, the non-bending part of the steel pipe is fixed by the transverse clamping assembly 33. The bending is performed in cooperation with the bending pipe assembly 4 through the movement adjustment of the adjusting table assembly 32. After the bending is completed, the steel pipe is taken out from the processing frame 410, and the steel pipe is pulled to one side by the transverse clamping assembly 33. The bent end of the steel pipe is fixed by the longitudinal clamping assembly 34, so as to avoid rebound of the steel pipe after bending and ensure the quality of the bent steel pipe.

[0051] In order to facilitate the bending of steel pipe fittings, Figures 7 - 8 As shown, the following preferred technical solutions are provided:

[0052] The adjustment table assembly 32 includes a movable plate 321 disposed at the upper end of the roller 31. A slider plate 322 is installed on the inner cavity bottom plate of the movable plate 321. A sliding block 323 is installed at the upper end of the slider plate 322. A shifting rack 324 is installed on the inner wall of the movable plate 321.

[0053] A sliding groove plate 325 is provided at the upper end of the slider plate 322. The notch at the lower end of the sliding groove plate 325 is slidably connected to the sliding block 323. A receiving chassis 326 for installing the transverse clamping assembly 33 is fixedly connected to the upper end of the sliding groove plate 325. A control motor 327 is installed at the upper end of the receiving chassis 326. A second position control gear 328 is installed at the output end of the control motor 327. The second position control gear 328 is meshed and connected with the shifting rack 324.

[0054] Specifically, when the transverse clamping assembly 33 needs to be adjusted horizontally, the control motor 327 is started to drive the second position control gear 328 to rotate. Through the cooperation of the second position control gear 328 and the shifting rack 324, the sliding groove plate 325 drives the transverse clamping assembly 33 to move in the inner cavity of the movable plate 321, facilitating the bending operation of the transverse clamping assembly 33 in cooperation with the steel pipe fitting.

[0055] As Figure 9 shown, the following preferred technical solutions are provided:

[0056] The transverse clamping assembly 33 and the longitudinal clamping assembly 34 have the same composition structure. The longitudinal clamping assembly 34 includes a power lifting main body 331. A lifting disc 332 is provided at the upper end of the lifting main body 331. A water pump 333 is installed at the upper end of the lifting disc 332. A clamping mechanism 334 is provided at the upper end of the water pump 333.

[0057] Specifically, through the cooperation of the lifting main body 331 and the lifting disc 332, the clamping mechanism 334 can be driven for height adjustment.

[0058] To facilitate the cooling of the preheated steel pipe fitting, as Figures 10 - 11 shown, the following preferred technical solutions are provided:

[0059] The clamping mechanism 334 includes an outer mounting block 3341 installed at the upper end of the water pump 333. A drainage channel 3342 is provided at the central position of the outer mounting block 3341. The drainage channel 3342 communicates with the output port of the water pump 333. A middle connection block 3343 is provided on the outer wall of the drainage channel 3342. A first spring 3344 and a second spring 3345 are respectively fixedly connected to both sides of the middle connection block 3343.

[0060] The first spring 3344 and the second spring 3345 are symmetrically distributed about the center of the middle connection block 3343. One end of the first spring 3344 away from the middle connection block 3343 is fixedly connected to a first clamping rod 3346, and one end of the second spring 3345 away from the middle connection block 3343 is fixedly connected to a second clamping rod 3347. A cooling nozzle 3348 is provided at the upper end of the drainage channel 3342.

[0061] Specifically, when positioning and fixing the steel pipe fitting, an external force is used to separate one end of the first clamping rod 3346 and the second clamping rod 3347. At this time, the first spring 3344 and the second spring 3345 will be pulled to a tightened state. After the steel pipe fitting is placed between the first clamping rod 3346 and the second clamping rod 3347, through the reaction force of the first spring 3344 and the second spring 3345, the first clamping rod 3346 and the second clamping rod 3347 clamp the steel pipe fitting to achieve the purpose of positioning and fixing.

[0062] After the longitudinal clamping assembly 34 fixes the bent end of the steel pipe fitting after bending, at this time, an external water source is connected and the water pump 333 is started. The water is sprayed out through the drainage channel 3342 and then through the cooling nozzle 3348, which can quickly cool the preheated and bent steel pipe fitting. It can not only improve the working efficiency, but also reduce the springback potential energy of the steel pipe fitting by reducing the temperature.

[0063] Such as Figure 11 shown, the following preferred technical solutions are provided:

[0064] A first pulley 3349 is installed at the upper opening of the first clamping rod 3346, and a second pulley 33410 is installed at the upper opening of the second clamping rod 3347.

[0065] Specifically, through the cooperation of the first pulley 3349 and the second pulley 33410, it is convenient for the steel pipe fitting to flip between the first clamping rod 3346 and the second clamping rod 3347, facilitating its cooperation with the bending work.

[0066] In order to further better explain and illustrate the above embodiments, the present invention also provides an implementation scheme, an implementation method of a pipe bender for processing stainless steel pipe fittings, including the following steps:

[0067] Step 1: When bending a steel pipe fitting, place the part of the steel pipe fitting to be bent into the processing frame 410 and make it fit against the bending wheel 411. Use the positioning component 3 to fix the other parts to ensure stability during the bending operation. Adjust the bending angle through the cooperation of the turntable body 41 and the concave mounting seat 42. By starting the power body 46, drive the top bending mechanism 48 to gradually approach the processing frame 410. Before the top bending mechanism 48 bends the steel pipe fitting, start the heating body 484 so that the heating block 485 emits heat. The emitted heat will enter the installation groove 487 through the heat discharge channel 486, and most of the heat will be absorbed by the heat conduction top plate 489. When the preheating top block 482 presses against the steel pipe fitting to be bent, the part of the steel pipe fitting to be bent will be preheated through the heat conduction top plate 489, which not only avoids cracking of the steel pipe fitting under pressure but also makes the bending efficiency higher;

[0068] Step 2: The roller 31 can drive the adjustment table assembly 32 to move longitudinally on the sliding table 2 to achieve the purpose of longitudinally adjusting the horizontal clamping assembly 33 and the longitudinal clamping assembly 34. The adjustment table assembly 32 can drive the horizontal clamping assembly 33 to perform horizontal movement adjustment. During the bending operation, the non-bending part of the steel pipe fitting is fixed by the horizontal clamping assembly 33. Through the movement adjustment of the adjustment table assembly 32 and in cooperation with the pipe bending assembly 4 for bending. After the bending is completed, take out the steel pipe fitting from the processing frame 410. Pull the steel pipe fitting outward to one side through the horizontal clamping assembly 33, and fix one end of the bent steel pipe fitting through the longitudinal clamping assembly 34, so as to avoid springback after the steel pipe is bent and ensure the quality of the bent steel pipe fitting;

[0069] Step 3: After the longitudinal clamping assembly 34 fixes one end of the bent steel pipe fitting after the bending is completed, connect to an external water source at this time, start the water pump 333, and spray the water through the cooling nozzle 3348 through the drainage channel 3342, which can quickly cool the preheated and bent steel pipe fitting. This not only improves the working efficiency but also reduces the springback potential energy of the steel pipe fitting by reducing the temperature.

6. An implementation method of a pipe bender for processing stainless steel pipe fittings as described in any one of claims 1-5, characterized in that, The following steps are involved: S1: When bending a steel pipe fitting, the portion of the steel pipe fitting to be bent is placed in the processing frame (410) and fitted with the bending wheel (411). The positioning assembly (3) is used to fix the other portions to ensure stability during the bending operation. The bending angle is adjusted by cooperating with the turntable body (41) and the concave mounting seat (42). The power body (46) is started to drive the top bending mechanism (48) to gradually move closer to the processing frame (410). Before bending the steel pipe fitting, the heating body (484) is started to make the heating block (485) emit heat, and the emitted heat enters the installation groove (487) through the heat exhaust channel (486), and most of the heat is absorbed by the heat-conducting top plate (489), so that when the preheating top block (482) is supported against the steel pipe fitting to be bent, the part of the steel pipe fitting to be bent is preheated by the heat-conducting top plate (489), which not only prevents the steel pipe fitting from cracking due to pressure, but also makes the bending efficiency higher; S2: The roller (31) can drive the adjustment table assembly (32) to move longitudinally on the sliding table (2), achieving the purpose of longitudinally adjusting the lateral clamping assembly (33) and the longitudinal clamping assembly (34). The adjustment table assembly (32) can drive the lateral clamping assembly (33) to perform lateral movement adjustment. When performing the bending operation, the non-bending part of the steel pipe is fixed by the lateral clamping assembly (33). Through the movement adjustment of the adjustment table assembly (32), it cooperates with the pipe bending assembly (4) to perform bending. After the bending is completed, the steel pipe is taken out from the processing rack (410). The steel pipe is pulled outward to one side by the lateral clamping assembly (33), and one end of the bent steel pipe is fixed by the longitudinal clamping assembly (34), thereby avoiding the springback of the steel pipe after bending and ensuring the quality of the bent steel pipe fittings; S3: After the longitudinal clamping assembly (34) fixes one end of the bent steel pipe after the bending is completed, at this time, an external water source is connected, the water pump (333) is started, and the water is sprayed out from the cooling nozzle (3348) through the drainage channel (3342), which can quickly cool the preheated and bent steel pipe. It can not only improve the working efficiency, but also reduce the springback potential energy of the steel pipe by reducing the temperature.
