Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe shearing equipment, and specifically relates to a steel pipe cutting machine tool for processing fluid connectors in production. Background Art

[0002] A fluid connector is a connecting device between fluid medium conveying pipelines. According to different connection methods, it is divided into bolt connection type, quick insertion connection type, flange connection type, etc. Commonly used materials include metal and non-metal materials. For some fluid connectors with relatively simple structures and small sizes, steel pipes are often used for processing. The steel pipes are pre-cut into appropriate lengths, and then operations such as cutting and threading are carried out.

[0003] Common methods include shearing and sawing. Although the sawing method can cut multiple steel pipes simultaneously, it will generate relatively large noise and a large amount of waste chips during operation, and it will also leave burrs on the cut steel pipes. Therefore, in some enterprises with strict requirements, the method of shearing with a circular rotating tool is selected. This method uses the circular tool to squeeze the steel pipe when rotating and uses the shearing force to cut off the steel pipe. The noise is relatively small during the process and no chips are generated. However, the shearing depth of this method is relatively shallow, and the existing equipment can only shear single steel pipes sequentially and cannot shear multiple steel pipes simultaneously, resulting in limited efficiency.

[0015] Compared with the prior art, the present invention provides a steel pipe cutting machine tool for processing fluid connectors, having the following beneficial effects: 1. By providing a bending and material receiving component, there are two bending and material receiving components. The one corresponding to the shear tool component is fixed, used to apply a shearing pressure to the steel pipe, and the one located on the electric slide is movable, used to push the steel pipe. Their structures and working methods are the same. When shearing is required, the hydraulic bending joints in the bending and material receiving component are in a horizontally unfolded state. Then, multiple steel pipes are placed in the shear sleeve and the material pushing sleeve. Subsequently, the hydraulic bending joints start to fold upward by using the internal hydraulic rotation component, so that the steel pipes they carry surround the outside of the shear tool component. Then, the shear tool component rotates at high speed, and at the same time, the hydraulic bending joints continue to bend, applying pressure to the steel pipe, so that the steel pipe is sheared, achieving the purpose of simultaneously shearing multiple steel pipes. While retaining the advantages of the shearing method, the production efficiency is greatly improved.

[0016] 2. By setting a shearing sleeve and a pushing sleeve, the shearing sleeve and the pushing sleeve are respectively arranged on two bending and material supporting components. The two can be simultaneously wound around the outside of the shearing tool component, and the shearing sleeve is of a through type, enabling the steel pipe to pass through it, achieving the purpose of positioning and supporting the steel pipe. Moreover, by utilizing the drive of the bending and material supporting components, pressure can be applied to the steel pipe, enabling the steel pipe to be smoothly sheared. When the tail end of the pushing sleeve is closed, the application can support the steel pipe and, by means of the movement of the sliding rod and the electric sliding seat, push the steel pipe towards the shearing tool component, realizing the effect of automatic feeding.

[0017] 3. By setting a pre-supporting component, the pre-supporting component is arranged between the two bending and material supporting components, and the top height is the same as that of the shearing sleeve and the pushing sleeve in the horizontal state. When carrying out the feeding work, the steel pipe can be first placed on the pre-supporting component, and then pushed into the shearing sleeve by the pushing sleeve, enabling batch feeding. Moreover, the pre-supporting component can be folded downwards so as not to affect the movement of the bending and material supporting components installed on the electric sliding seat.

[0020] 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.

[0021] Please refer to Figure 1-14 , a steel pipe cutting machine tool for processing fluid connectors, including a base 1. At both ends of the base 1, there are bending and loading components 2. On the two bending and loading components 2, there are respectively a plurality of shearing sleeves 4 and pushing sleeves 5. At the position corresponding to the shearing sleeves 4 on the base 1, there is a shearing tool component 3. On the base 1, there is a slide rail 8. On the slide rail 8, there is an electric slide 9. The electric slide 9 is arranged below the bending and loading component 2 where the pushing sleeve 5 is installed; As Figure 1 shown, by setting the slide rail 8 and the electric slide 9, the slide rail 8 and the electric slide 9 can be driven by electricity to move horizontally along a defined direction, so that it can drive the pushing sleeve 5 through the bending and loading component 2 to push the steel pipe. The slide rail 8 and the electric slide 9 preferably adopt linear motors. In addition, the structural principle of the linear motor is well-known to those skilled in the art, so it will not be elaborated here.

[0022] The bending and loading component 2 includes a vertical plate 201 arranged on the base 1 and the electric slide 9. On the vertical plate 201, a horizontal plate 202 is fixedly arranged. At both ends of the horizontal plate 202, a plurality of hydraulic bending joints 203 are connected in series. On the hydraulic bending joints 203, there is a loading frame 204 connected to the shearing sleeve 4 and the pushing sleeve 5. The hydraulic bending joint 203 includes a hydraulic rotation component 2032. The main body of the hydraulic rotation component 2032 is fixedly connected to the horizontal plate 202 and the adjacent hydraulic bending joint 203. The output end of the hydraulic rotation component 2032 is fixedly provided with a bearing plate 2031. The bearing plate 2031 is arranged under the loading frame 204. At one end of the bearing plate 2031 away from the hydraulic rotation component 2032, there is a first bearing part 2033 connected to the adjacent hydraulic bending joint 203; As Figure 2 shown, by setting the bending and loading component 2, there are two bending and loading components 2. The one corresponding to the shearing tool component 3 is fixed, which is used to apply shearing pressure to the steel pipe. The one located on the electric slide 9 is movable, which is used to push the steel pipe. Their structures and working methods are the same. When shearing is required, the hydraulic bending joints 203 in the bending and loading component 2 are in a horizontal unfolded state. Then, a plurality of steel pipes are placed in the shearing sleeves 4 and the pushing sleeves 5. Subsequently, the hydraulic bending joints 203 start to fold upward by using the internal hydraulic rotation component 2032, so that the steel pipes they carry are wound around the outside of the shearing tool component 3. Then, the shearing tool component 3 rotates at a high speed, and at the same time, the hydraulic bending joints 203 continue to bend, applying pressure to the steel pipe, so that the steel pipe is sheared, achieving the purpose of shearing multiple steel pipes simultaneously. While retaining the advantages of the shearing method, the production efficiency is greatly improved. The number of series-connected bending joints is proportional to the shearing tool component 3, that is, the larger the size of the shearing tool, the more the number of bending joints.

[0023] The hydraulic rotary assembly 2032 includes a hydraulic cylinder body 20321 connected to the cross plate 202 and the adjacent hydraulic bending joint 203. A rotating shaft 20325 fixedly connected to the bearing plate 2031 is provided inside the hydraulic cylinder body 20321. A gear 20326 located inside the hydraulic cylinder body 20321 is provided on the rotating shaft 20325. A rack 20324 meshes with the side of the gear 20326. Piston plates 20322 which are in sliding and sealing fit with the inner wall of the hydraulic cylinder body 20321 are provided at both ends of the rack 20324. Oil ports 20323 communicating with an external hydraulic supply device are provided at positions corresponding to the piston plates 20322 on the side surface of the hydraulic cylinder body 20321; As Figure 5 and Figure 6 shown, by providing the hydraulic rotary assembly 2032, the hydraulic rotary assembly 2032 can convert linear motion into rotary motion by relying on the internal rack 20324 and gear 20326. During operation, hydraulic oil is injected into the hydraulic cylinder body 20321 at the corresponding position. The hydraulic oil pushes the corresponding piston plate 20322 to move. The piston plate 20322 then drives the gear 20326 to rotate through the rack 20324. The gear 20326 then drives the bearing plate 2031 fixedly connected thereto to rotate through the rotating shaft 20325, achieving the purpose of bending. Multiple hydraulic rotary assemblies 2032 work simultaneously to achieve the effect of surrounding the shearing tool component 3. Moreover, using hydraulic drive has better stability and greater driving force, which can meet the pressure required when shearing steel pipes.

[0024] The material supporting frame 204 includes a hollow frame body 2041 provided on the bearing plate 2031. A positioning groove 2042 is provided on the hollow frame body 2041. A pressure sensor 2043 is provided inside the hollow frame body 2041; As Figure 5 shown, by providing the positioning groove 2042 and the pressure sensor 2043, the positioning groove 2042 can be engaged with the first positioning member 405 and the second positioning member 504. When shearing steel pipes of different sizes, it is necessary to replace the shearing sleeve 4 and the pushing sleeve 5 with appropriate specifications. The positioning groove 2042 can enable better and faster alignment and positioning, saving the work of positioning and calibration. The pressure sensor 2043 can detect the pressure received by the shearing sleeve 4. That is, when the shearing sleeve 4 presses the steel pipe towards the shearing tool component 3, the pressure sensor 2043 can feedback the pressure in real time to determine whether the pressure applied to the steel pipe meets the shearing requirement, ensuring that the pressure applied to the steel pipe is consistent, so that all steel pipes can complete the shearing work synchronously.

[0025] The shearing sleeve 4 includes a first cylinder body 401. A first connecting plate 404 connected to the hollow frame body 2041 is provided below the first cylinder body 401. A first positioning member 405 fitted with the positioning groove 2042 is provided below the first connecting plate 404. A second bearing member 402 is provided inside the first cylinder body 401. A cutter groove 403 aligned with the shearing tool component 3 is provided inside the first cylinder body 401. As Figure 7 shown, by providing the first cylinder body 401 and the second bearing member 402, the first cylinder body 401 is of a through type, enabling it to be sleeved on the steel pipe to achieve the purpose of driving the steel pipe to move. The second bearing member 402 is spaced between the first cylinder body 401 and the steel pipe, making the steel pipe rotate more smoothly during shearing and avoiding friction between the outer surface of the steel pipe and the inner wall of the first cylinder body 401. The cutter groove 403 provided inside the first cylinder body 401 does not contact the shearing tool component 3, and its position is aligned with the shearing tool component 3, only serving to indicate the shearing position.

[0026] The feeding sleeve 5 includes a second cylinder body 501. A second connecting plate 503 connected to the hollow frame body 2041 is provided below the second cylinder body 501. A second positioning member 504 fitted with the positioning groove 2042 is provided below the second connecting plate 503. A third bearing member 505 is provided inside the second cylinder body 501. A rubber anti-slip ring 506 is provided on the inner wall of the third bearing member 505. An infrared sensor 502 is provided at the tail end of the second cylinder body 501. As Figure 8 shown, by providing the second cylinder body 501 and the third bearing member 505, when the tail end of the second cylinder body 501 is closed, it can contact the tail end of the steel pipe to achieve the purpose of pushing the steel pipe to move. The third bearing member 505 has the same function as the second bearing member 402, that is, it supports the steel pipe and avoids the problem of friction between the steel pipe and the inner wall of the second cylinder body 501. Additionally, it should be noted that the inner diameter sizes of the second bearing member 402 and the third bearing member 505 are slightly larger than the outer diameter size of the steel pipe, and this method can ensure that the steel pipe can be smoothly inserted therein; Meanwhile, it should be noted that a rubber anti-slip ring 506 is provided inside the third bearing member 505. When the steel pipe is inserted into the third bearing member 505, the rubber anti-slip ring 506 will closely contact the steel pipe, and the steel pipe is fixed by the frictional force, so that the steel pipe will not be randomly removed from the third bearing member 505 without external force, avoiding the problem that the steel pipe is displaced during the pushing of the steel pipe, resulting in inconsistent lengths after shearing. The rubber anti-slip ring 506 will rotate along with the inner ring of the third bearing member 505, so there will be no friction problem with the outer wall of the steel pipe.

[0027] The shearing tool component 3 includes a fixed frame 301 provided on the base 1. A driving shaft 303 is provided inside the fixed frame 301. A driving motor 302 is connected to the end face of the driving shaft 303. A circular shearing cutter 304 is provided on the driving shaft 303. AsFigure 9 As shown, by setting the circular cutting tool 304, the circular cutting tool 304 is a toothedless disc with high hardness, and the cutting edge is a circle on the outermost ring. Its working method is to cut off the steel pipe by squeezing it, and no debris will be generated during the process, and the noise is relatively small. In this embodiment, the circular cutting tool 304 is supported and driven by the drive shaft 303 and does not generate displacement itself. When cutting, the bending material receiving component 2 squeezes the steel pipe towards the circular cutting tool 304. Using this method also has the advantage of uniform force distribution, avoiding the wear problem of the drive shaft 303 caused by unidirectional force.

[0028] A plurality of adaptive linkage components 305 are provided on the side of the circular cutting tool 304. The adaptive linkage components 305 drive the steel pipe to rotate automatically by using friction when the circular cutting tool 304 rotates; The adaptive linkage component 305 includes a fixed plate 3051 provided on the side of the circular cutting tool 304. A sliding rod 3052 is slidably provided in the fixed plate 3051. An arc-shaped plate 3054 adapted to the circular edge of the circular cutting tool 304 is provided on the sliding rod 3052. A first spring 3053 is provided directly between the sliding rod 3052 and the fixed plate 3051. Anti-slip stripes 3055 are provided on the arc-shaped plate 3054; As Figure 10 shown, by setting the sliding rod 3052 and the arc-shaped plate 3054, the radian of the arc-shaped plate 3054 fits the outer ring of the circular cutting tool 304 and is in the same position as the outer ring of the circular cutting tool 304 under normal conditions. When the circular cutting tool 304 rotates, the arc-shaped plate 3054 will follow the rotation and drive the steel pipe to rotate by using its own anti-slip stripes 3055, so that the steel pipe can contact the circular cutting tool 304 all around and then be cut off. In this way, the cutting depth of the circular cutting tool 304 only needs to reach the wall thickness of the steel pipe, greatly improving the cutting effect. And by driving the steel pipe to rotate, the force on the steel pipe is uniform, avoiding the problem of being squeezed and deformed during cutting. In addition, the movement of the arc-shaped plate 3054 completely depends on the original rotation movement of the circular cutting tool 304, so that no additional driving equipment needs to be set for the rotation of the steel pipe; In addition, the sliding rod 3052 is slidably connected to the fixed plate 3051, so that when the circular cutting tool 304 cuts into the steel pipe, the arc-shaped plate 3054 and the sliding rod 3052 can contract towards the center, thus avoiding the arc-shaped plate 3054 from affecting the cutting work of the circular cutting tool 304. The first spring 3053 supports the sliding rod 3052, so that the sliding rod 3052 can quickly reset after losing external force.

[0029] One of the fixing plates 3051 is provided with an anti-slip powder spraying component 306 for increasing the friction between the arc-shaped plate 3054 and the steel pipe. The top of the anti-slip powder spraying component 306 penetrates through the arc-shaped plate 3054, and the anti-slip powder spraying component 306 can be in any posture when the circular shear blade 304 rotates. When the circular shear blade 304 is stationary, the anti-slip powder spraying component 306 must be in a vertically upward posture; The anti-slip powder spraying component 306 includes a connecting piece 3061 provided on the fixing plate 3051. A powder storage tank 3062 is provided on the connecting piece 3061. A spraying pipe 3064 that penetrates through the arc-shaped plate 3054 and is fixedly connected thereto is slidably provided in the powder storage tank 3062. A second spring 3063 connected between the arc-shaped plate 3054 and the powder storage tank 3062 is sleeved on the spraying pipe 3064. A filler port 3066 is provided at the bottom of the spraying pipe 3064. A groove 3067 that fits with the filler port 3066 is provided under the powder storage tank 3062. A transparent window 3065 is provided on the side of the powder storage tank 3062 Such as Figure 10 And Figure 11 As shown, by providing the spraying pipe 3064 and the groove 3067, the spraying pipe 3064 is a hollow pipe that is vertically penetrated, and a filler port 3066 corresponding to the groove 3067 is provided at the bottom. In the normal state, the powder in the powder storage tank 3062 will flow into the groove 3067. When the arc-shaped plate 3054 contacts the steel pipe and is squeezed, the spraying pipe 3064 will drive the filler port 3066 at the bottom to insert into the groove 3067. At this time, the powder in the groove 3067 will be in the spraying pipe 3064. At the same time, the filler port 3066 will use its fit with the groove 3067 to seal it, so that the powder in the storage pipe will not flow into the groove 3067 at this time. As the arc-shaped plate 3054 rotates, the powder in the spraying pipe 3064 will be thrown out under the action of centrifugal force, so that it contacts the steel pipe in the outer circle, and the powder is used to increase the friction between the steel pipe and the arc-shaped plate 3054, avoiding the problem of slipping and further ensuring the stable rotation of the steel pipe. It should be noted that the powder is preferably a powder that is insoluble in water and has a hardness lower than that of the steel pipe, preventing the powder from fusing and becoming sticky and being difficult to clean, and at the same time avoiding the problem of scratching the surface of the steel pipe by the powder; When the arc-shaped plate 3054 is reset, the spraying pipe 3064 will be reset by using the second spring 3063 at the same time, and the filler port 3066 will be separated from the groove 3067. The powder in the powder storage tank 3062 will automatically be replenished into the groove 3067 to wait for subsequent work. And no additional driving equipment is required during the implementation process, but the above-mentioned limited requirements need to be followed. In the stationary state, the anti-slip powder spraying component 306 needs to be vertically upward.

[0030] A pre-support component 6 flush with the shear sleeve 4 and the push sleeve 5 is provided in the base 1; The pre-support component 6 includes a support shaft 603 provided in the base 1. A support plate 602 is fixedly provided on the support shaft 603. A first reduction motor 601 is connected to the side of the support shaft 603. A support plate 604 is provided on the support plate 602. A material placement groove 605 for placing steel pipes is provided on the support plate 604. As Figure 12 shown, by providing the pre-support component 6, the pre-support component 6 is provided between the two bent material receiving components 2, and the top height is the same as that of the shearing sleeve 4 and the pushing sleeve 5 in the horizontal state. When loading materials, the steel pipe can be first placed on the pre-support component 6, and then pushed into the shearing sleeve 4 by the pushing sleeve 5, so that batch loading can be carried out. Moreover, the pre-support component 6 can be folded downwards so as not to affect the movement of the bent material receiving component 2 installed on the electric slide 9.

[0031] A stepping feeding component 7 for feeding the steel pipe to the material placement groove 605 is provided on the side of the support plate 602; The stepping feeding component 7 includes a second reduction motor 701 provided on the side of the support plate 602. An output shaft 702 extending at both ends is provided in the second reduction motor 701. A bevel gear set 703 is provided on the end face of the output shaft 702. The other end of the bevel gear 20326 is provided with a linkage shaft 704 rotatably provided in the support plate 602. A linkage arm 705 is fixedly provided on the end face of the linkage shaft 704. A support frame 706 is rotatably provided on the end face of the linkage arm 705. A bracket 707 is fixedly provided on the support frame 706. A clamping groove 708 for placing the steel pipe is provided on the bracket 707; As Figure 14 shown, by providing the linkage shaft 704 and the linkage arm 705, the linkage shaft 704 can rotate under the drive of the output shaft 702 and the bevel gear set 703. When rotating, it will drive the linkage arms 705 at both ends to do circular motion. The linkage arm 705 will drive the bracket 707 to do circular motion by using the support frame 706, so that the clamping groove 708 on the bracket 707 realizes the stepping effect. Matching with equipment such as a conveyor belt can achieve the purpose of automatically feeding the pre-support component 6.

[0032] A fitting strip 606 is provided on the support plate 602. A fitting groove 607 is provided under the support plate 604. A bolt member 608 passing through itself and connecting to the support plate 602 is provided on the support plate 604; As Figure 13 shown, by providing the fitting strip 606 and the fitting groove 607, the fitting strip 606 and the fitting groove 607 can be quickly pre-connected by inserting, and then fixed by using the bolt member 608. By this method, the support plate 604 can be replaced to facilitate its adaptation to steel pipes of different sizes.

[0033] Working principle: The external conveyor belt transports the steel pipe to the stepping feeding component 7, and the stepping feeding component 7 transports the steel pipe to the pre-supporting component 6. Then, the electric sliding seat 9 moves on the slide rail 8, connects the pushing sleeve 5 with the tail end of the steel pipe, and pushes the steel pipe into the shearing sleeve 4. Then, the bending material receiving component 2 bends upwards, fitting the steel pipe outside the shearing tool component 3, and uses the rotating shearing tool component 3 to shear the steel pipe. During the feeding process of the steel pipe, the pre-supporting component 6 folds downwards to avoid the moving bending material receiving component 2.

[0034] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
