[0002] A wet gearbox is a gearbox that transmits power through lubricating oil and is composed of gears, shafts, oil seals, oil tanks, oil pumps, oil pipes, oil filters and other components. When the gears are running, the lubricating oil will be sucked into the oil tank by the oil pump, and then flow into the gearbox through the oil pipe, which can reduce the friction and wear between the gears in the gearbox, and at the same time reduce the transmission noise and temperature. The pipe bending transmission type pipe bending machine is a type of pipe bending machine. It is mainly used to bend metal pipes into different shapes to meet the needs of industrial manufacturing, construction, automobiles and other fields. Therefore, the wet gearbox pipe bending transmission type pipe bending machine is a mechanical equipment that uses a wet gearbox for transmission and is used to bend pipes.

[0009] Furthermore, the detection mechanism includes a side connecting plate, the inner surface of which is rotatably connected to a connecting rod, and one end of the connecting rod away from the side connecting plate is rotatably connected to a protective component.

The pipe is sent into the clamping device by the movement of the mobile platform, which can replace manual alignment of the pipe, avoiding the problem of manual arm shaking during the alignment process, which leads to prolonged pipe bending time.

[0015] 2. When the metal pipe needs to be moved forward for bending, the two support plates of this device will be separated from the lower surface of the pipe, so that the pipe will not be worn during the movement, resulting in damage to the pipe surface and affecting the bending. At the same time, multiple clamping wheels are attached to the outer surface of the pipe to limit its position, preventing it from shaking or deflecting during the bending or moving process, resulting in the problem of being unable to bend the pipe.

[0016] 3. This device will drive the clamping wheel to rotate during the movement of the pipe. When there is a protrusion on the surface of the pipe and it contacts the clamping wheel, it will push the clamping wheel and the connecting plate to move, causing the connecting rod to rotate and transmit the pressure to the pressure gauge. It can detect whether there are protrusion defects at certain positions on the surface of the pipe, avoiding the problem of unsatisfactory bending shape due to protrusions in certain parts during the subsequent bending process.

[0017] 4. In the process of the pressure gauge being squeezed by the connecting rod, the pressure gauge and the sleeve plate will rotate along the outer surface of the vertical axis, and the squeezing force will be relieved by the squeezing belt, so as to avoid the pressure gauge being always fixed and being damaged due to the inability to move when being squeezed by the connecting rod.

[0018] 5. When the pressure wheel feels the bulge on the surface of the pipe, the sponge block inside the marking component will slide toward one side of the arc groove together with the clamping box and the hollow tube, so that the marking liquid inside the pressure wheel enters the sponge block through the liquid inlet hole, so that the sponge block fits the pipe and marks its bulge, avoiding the problem that the bulge of the pipe is not marked, which makes the staff unable to find it quickly, thereby affecting the subsequent processing and repair speed of the defective pipe.

DETAILED DESCRIPTION

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0022] For example, see Figure 1-Figure 5 The present invention provides a technical solution: a wet gear box bending transmission type pipe bending machine, comprising a processing box 1, a clamping device 2 is slidably connected to the upper surface of the processing box 1, an alignment mechanism 3 is slidably connected to the upper surface of the processing box 1, and a detection mechanism 4 is fixedly connected to the upper surface of the alignment mechanism 3; the processing box 1 provides support for the clamping device 2 and the alignment mechanism 3, the clamping device 2 can clamp the metal pipe to be bent, after the metal pipe is placed on the surface of the alignment mechanism 3, it is assisted and corrected by the alignment mechanism 3, so that it can better enter the center of the clamping device 2 and be clamped by the clamping device 2, which is convenient for the subsequent bending operation of the metal pipe.

[0023] First, place the metal pipe to be bent on the upper surface of the alignment mechanism 3. After its position is limited by the alignment mechanism 3, it is sent into the interior of the clamping device 2 instead of being manually operated to facilitate the clamping device 2 to clamp it. The detection mechanism 4 detects the outer surface of the metal pipe to detect whether there are any large protrusions on its outer surface.

[0024] The alignment mechanism 3 includes a round wheel 31, a screw rod 32 is fixedly connected to one side of the round wheel 31, a moving plate 33 is threadedly connected to the outer surface of the screw rod 32, a square box 34 is slidably connected to the bottom of the moving plate 33, a moving platform 35 is slidably connected to the upper surface of the moving plate 33, an inclined plate 36 is fixedly connected to the upper surface of the moving platform 35, a support frame 37 is fixedly connected to the side of the inclined plate 36 away from the moving platform 35, a pressing component 38 is arranged above the support frame 37, a rotating shaft 39 is rotatably connected to the inner wall of the support frame 37, both ends of the rotating shaft 39 are fixedly connected to the output end of the servo motor 301, and a support plate 302 is fixedly connected to the outer surface of the rotating shaft 39. The screw rod 32 can make the moving plates 33 on both sides move away from or close to each other when rotating, and the pressing component 38 can achieve preliminary clamping of the two sides of the metal pipe, and the support of the support plate 302 on the metal pipe can further fix the position of the metal pipe.

[0025] The outer surface of the screw rod 32 is rotatably connected to the inner wall of the square box 34 , the bottom of the square box 34 is fixedly connected to the upper surface of the processing box 1 , and the outer surface of the servo motor 301 is fixedly connected to the inner surface of the support frame 37 .

[0026] The metal pipe is placed on the upper surface of the support plate 302. In the process of placing the metal pipe downward, the clamping components 38 on both sides will be squeezed, and the two sides of the metal pipe will be properly clamped by the clamping components 38. When the position of the metal pipe is determined, the moving platform 35 located on both sides of the metal pipe is started, which can drive the inclined plate 36, the support frame 37, and the clamping component 38 to slide along the upper surface of the moving plate 33, and send one end of the metal pipe into the center of the clamping device 2. The outer surface of the metal pipe is clamped by the clamping device 2, instead of manually sending the metal pipe into the center of the clamping device 2, avoiding the problem of misalignment when manually sending the pipe into the clamping device 2, thereby causing the bending time to be extended.

[0027] The clamping component 38 includes a central clamping device 381, and side clamping devices 382 are symmetrically arranged on both sides of the central clamping device 381. The outer surface of the central clamping device 381 is fixedly connected to the inner surface of the inclined plate 36, and the outer surface of the side clamping device 382 is fixedly connected to the inner surface of the inclined plate 36. The central clamping device 381 and the side clamping devices 382 on both sides are used to position and clamp the outer surface of the metal pipe, and the inclined plate 36 plays a role in fixing the central clamping device 381 and the side clamping devices 382.

[0028] The central clamping device 381 includes an arc tube 3811, the outer surface of which is provided with a transverse groove 3812, the inner wall of the arc tube 3811 is fixedly connected with a spring belt 3813, the end of the spring belt 3813 away from the inner wall of the arc tube 3811 is fixedly connected to the top of the bending rod 3814, the outer surface of the bending rod 3814 is rotatably connected with a clamping wheel 3815, the outer surface of the clamping wheel 3815 is provided with an arc groove 3816, the inner surface of the clamping wheel 3815 is slidably connected with a piston 3817, the outer surface of the arc tube 3811 is fixedly connected to the inner surface of the inclined plate 36, and the outer surface of the bending rod 3814 is slidably connected to the inner surface of the arc tube 3811. The transverse groove 3812 facilitates the sliding of the internal parts of the subsequent detection mechanism 4. The spring belt 3813 has the same function as the spring, and both have elasticity and reset functions. The upper surface of the clamping wheel 3815 is set to an arc surface, which is convenient for the metal pipe to slide downward along its surface and squeeze the clamping wheel 3815. On the one hand, the clamping wheel 3815 plays a role in limiting the metal pipe, and on the other hand, it can be used to detect the protrusions on the surface of the metal pipe.

[0029] When the metal pipe is placed on the upper surface of the support plate 302, the pipe will move downward and touch the central clamping device 381 and the side clamping devices 382 on both sides, that is, touch the multiple clamping wheels 3815, and push the clamping wheels 3815 and the bending rod 3814 to move to the side away from the pipe. During the movement, the bending rod 3814 will slide inward along the inner surface of the bent pipe and squeeze the spring belt 3813. The multiple clamping wheels 3815 will clamp and limit both sides of the pipe to avoid shaking or deviation during transportation.

[0030] When the metal pipe is clamped by the clamping device 2, it is necessary to bend the pipe. The clamping device 2 will drive the pipe to move forward so that the other end of the pipe is bent by the external bending device. Before the pipe moves forward, the servo motor 301 controls the rotating shaft 39 and the support plate 302 to rotate to the side away from the clamping component 38, that is, the upper surface of the support plate 302 is out of contact with the lower surface of the pipe. At this time, the bent pipe is bent by the clamping device 2 and the external bending device. Therefore, during the advancement of the pipe, the support plate 302 will not contact the lower surface of the pipe and will not cause wear to the lower surface of the pipe. However, during the advancement of the pipe, the pipe will contact the clamping components 38 on both sides and can drive the clamping wheel 3815 to rotate around the outer surface of the bending rod 3814.

[0031] For example 2, please refer to Figure 1-Figure 8The present invention provides a technical solution: on the basis of the first embodiment, the detection mechanism 4 includes a side connecting plate 41, the inner surface of the connecting plate 41 is rotatably connected with a connecting rod 42, and one end of the connecting rod 42 away from the side connecting plate 41 is rotatably connected with a protective component 43. The side connecting plates 41 and the connecting rod 42 are arranged on both sides of the central clamping device 381. When the clamping wheel 3815 on one side is squeezed, the side connecting rod 42 can be driven to move through the bending rod 3814, wherein the connecting rod 42 is made of a soft rubber material, which can have a certain elastic deformation ability and will not be damaged when subjected to a certain deformation force.

[0032] The protective component 43 includes a fixed plate 431, and a curved plate 432 is fixedly connected to the side of the fixed plate 431 away from the bending rod 3814, and a vertical axis 433 is rotatably connected to the inner surface of the curved plate 432 away from the fixed plate 431, and both ends of the vertical axis 433 are fixedly connected to a sleeve plate 434, and a pressure gauge 435 is fixedly connected to the inner wall of the sleeve plate 434, and an extrusion belt 436 is fixedly connected to the end of the sleeve plate 434 away from the pressure gauge 435, and a marking component 44 is arranged below the extrusion belt 436. The fixed plate 431 can slide along the inner surface of the transverse groove 3812 under the sliding of the bending rod 3814 to adapt to the width of the metal pipe. The extrusion belt 436 has the same function as the spring, and both have elasticity and reset functions. The pressure gauge 435 is used to measure the pressure. A protective component 43 is provided with two pressure gauges 435. The positions of the two pressure gauges 435 are respectively aligned with the surfaces of the upper and lower rods of the connecting rod 42. After the pressure gauge 435 is squeezed, the extrusion belt 436 can play a buffering role to protect the pressure gauge 435.

[0033] The side of the fixing plate 431 away from the arc plate 432 is fixedly connected to the outer surface of the bending rod 3814 , and the side of the extrusion belt 436 away from the sleeve plate 434 is slidably connected to the outer surface of the arc tube 3811 .

[0034] When the metal pipe squeezes the clamping wheel 3815, it will push the clamping wheel 3815 to move to the side close to the bent pipe. At the same time, the metal pipe will squeeze multiple clamping wheels 3815, so that multiple clamping wheels 3815 move to one side of the bent pipe together. The clamping wheel 3815 will also drive the movement of the bending rod 3814 and the connecting plate 41, the connecting rod 42 and the protective component 43. If there is no large protrusion on the surface of the pipe where the clamping wheel 3815 is in contact with the pipe, the moving distance of the three clamping wheels 3815 should be the same. When the pipe is in contact with the clamping wheel 3815 inside one of the side clamping devices 382, ​​the clamping wheel 3815 will move to the side of the bent pipe. When there is a large protrusion on the surface, it will push the contacting clamping wheel 3815 to move a certain distance. At this time, the connecting plate 41 will drive the connecting rod 42 to move forward a certain distance, and the other end of the connecting rod 42, that is, the end located at the center clamping device 381, will rotate along the inner surface of the fixed plate 431 toward the side close to the protective component 43, and squeeze the pressure gauge 435 on one side. When the pressure gauge 435 feels the pressure, it indicates that there is a certain protrusion on the surface of the pipe that fits the clamping wheel 3815 inside the side clamping device 382, ​​that is, the bent pipe has certain defects and the bending operation needs to be stopped.

[0035] When one side of the connecting rod 42 touches the pressure gauge 435, the pressure gauge 435 will be squeezed. Since the connecting rod 42 is rotating and touching, after the pressure gauge 435 feels the squeezing force, it will also drive the sleeve plate 434 to rotate a certain angle along the outer surface of the vertical axis 433 toward the side close to the squeezing band 436, and squeeze the squeezing band 436 to buffer the squeezing force on the pressure gauge 435, so as to avoid the problem that the pressure gauge 435 is fixed in position and squeezed by the rotation of the connecting rod 42, which may cause damage.

[0036] The marking component 44 includes a telescopic rod 441, a bent plate 442 is fixedly connected to the output end of the telescopic rod 441, a clamping box 443 is fixedly connected to the side of the bent plate 442 close to the arc groove 3816, a sponge block 444 is fixedly connected to the inner surface of the clamping box 443, a hollow tube 445 is fixedly connected to the side of the clamping box 443 close to the telescopic rod 441, a liquid inlet hole 446 is provided on the outer surface of the hollow tube 445, a round tube 447 is slidably connected to the outer surface of the hollow tube 445, and a horizontal plate 448 is fixedly connected to both sides of the round tube 447. The initial position of the clamping box 443 is inside the arc groove 3816, and does not extend out. The inside of the clamping box 443 is connected to the inside of the hollow tube 445, which is convenient for the circulation of the marking liquid. The sponge block 444 can be used to absorb the marking liquid to mark the defective parts on the surface of the metal pipe.

[0037] One end of the telescopic rod 441 away from the bent plate 442 is fixedly connected to the inner surface of the clamping wheel 3815, the outer surface of the clamping box 443 is slidably connected to the inner surface of the arc groove 3816, and the side of the horizontal plate 448 away from the circular tube 447 is fixedly connected to the inner surface of the clamping wheel 3815.

[0038] When the connecting rod 42 rotates and touches the pressure gauge 435, it indicates that there is a certain protrusion on the side of the pipe. It is necessary to mark the area near the protrusion to facilitate the staff to handle and subsequently trim the protrusion to ensure the quality and performance of the pipe.

[0039] In the initial state, there is a certain amount of marking liquid inside the clamping wheel 3815. When the marking liquid is insufficient, the piston 3817 can be opened to supply a certain amount of marking liquid inside. At the same time, the pipe will push the rotation of the clamping wheel 3815 during its advancement. When the pressure gauge 435 feels the pressure, the telescopic rod 441 inside the clamping wheel 3815 that is squeezed by the protrusion of the pipe is controlled to contract, which can drive the bending plate 442, the hollow tube 445, the clamping box 443, and the sponge block 444 to move toward the side close to the arc groove 3816, so that the sponge block 444 fits the outer surface of the pipe. When the hollow tube 445 moves along the inner surface of the circular tube 447 toward the side close to the clamping box 443, the liquid inlet hole 446 will be moved from the inner surface of the hollow tube 445 to the inner surface of the clamping box 443. The inner surface is moved out, so that the marking liquid inside the clamping wheel 3815 can flow into the interior of the hollow tube 445 through the liquid inlet hole 446, and further enter the interior of the clamping box 443 and the sponge block 444. When the clamping wheel 3815 rotates, it will drive the sponge block 444 to have friction contact with the outer surface of the pipe, and then a certain amount of marking liquid will be attached to the vicinity of the protrusion of the pipe, which is convenient for the staff to quickly find it. After marking, the telescopic rod 441 extends, driving the bent plate 442 and the clamping box 443 to reset, so that the liquid inlet hole 446 opened on the outer surface of the hollow tube 445 enters the interior of the circular tube 447 again, so that the liquid inlet hole 446 is blocked, and the marking liquid inside the clamping wheel 3815 will not enter the interior of the hollow tube 445 and the sponge block 444.

[0040] Since the clamp box 443 and the sponge block 444 are symmetrically arranged on both sides of the inside of the clamping wheel 3815, when the sponge block 444 on one side first touches the pipe and marks the outer surface of the pipe, the other telescopic rod 441 stops shrinking, so that the other sponge block 444 does not contact the outer surface of the pipe, resulting in the problem of wrong marking. A sensor is arranged at the contact point between the inner surface of the clamp box 443 and the sponge block 444. The position of the sensor does not prevent the marking liquid from entering the inside of the sponge block 444, but can sense the pressure on the sponge block 444, and then transmit the pressure to the other telescopic rod 441, so that it no longer shrinks.

[0041] The specific working process of the present invention is as follows: First, the support plate 302 inside the alignment mechanism 3 provides support for the metal pipe, and then cooperates with the clamping wheels 3815 inside the central clamping device 381 and the side clamping device 382 to clamp and limit the two sides of the pipe. The pipe is sent into the clamping device 2 by moving the movable platform 35, which can replace manual alignment operations on the pipe, avoiding the problem of manual arm shaking during the alignment process, which in turn leads to prolonged bending time of the pipe.

[0042] When the metal pipe needs to be moved forward for bending, the two support plates 302 are separated from the lower surface of the pipe, so that the pipe will not be worn during the movement, resulting in damage to the pipe surface and affecting the bending. At the same time, multiple clamping wheels 3815 are attached to the outer surface of the pipe to limit its position, so as to prevent it from shaking or deflecting during the bending or moving process, resulting in the problem of being unable to bend the pipe.

[0043] When the clamping wheel 3815 is driven to rotate during the movement of the pipe, when there is a protrusion on the surface of the pipe and it comes into contact with the clamping wheel 3815, it will push the clamping wheel 3815 and the connecting plate 41 to move, causing the connecting rod 42 to rotate and transmit the pressure to the pressure gauge 435. It can detect whether there are protrusion defects at certain positions on the surface of the pipe, thereby avoiding the problem of unsatisfactory bending shape due to protrusions in certain positions during the subsequent bending process.

[0044] When the pressure gauge 435 is squeezed by the connecting rod 42, the pressure gauge 435 will rotate together with the sleeve plate 434 along the outer surface of the vertical axis 433, and the squeezing force will be relieved by the squeezing belt 436 to prevent the pressure gauge 435 from being always fixed in position and being damaged due to the inability to move when being squeezed by the connecting rod 42.

[0045] When the pressure wheel 3815 senses the protrusion on the surface of the pipe, the sponge block 444 inside the marking component 44 will slide toward one side of the arc groove 3816 together with the clamping box 443 and the hollow tube 445, so that the marking liquid inside the pressure wheel 3815 enters the interior of the sponge block 444 through the liquid inlet hole 446, so that the sponge block 444 fits the pipe and marks its protruding parts, avoiding the problem of unmarked protruding parts of the pipe, which makes the staff unable to find them quickly, thereby affecting the subsequent processing and repair speed of the defective pipe.
