Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe shearing equipment, in particular to a steel pipe cutting machine bed for producing fluid connector processing. BACKGROUND

[0002] The fluid connector is a connecting device for fluid medium conveying pipelines, which is divided into bolt connection type, quick plug connection type and flange connection type according to different connection modes, and commonly used are metal materials and non-metal materials. Some fluid connectors with simple structure and small size are often processed by steel pipes, which are cut into appropriate lengths in advance, and then subjected to cutting, threading and other work.

[0003] The commonly used methods are shearing and sawing. Although the sawing method can cut multiple steel pipes at the same time, it produces a lot of noise and a large amount of waste during work, and also leaves burrs on the cut steel pipes. Therefore, some enterprises with strict requirements will choose the circular rotary cutter shearing method, which uses a circular cutter to extrude the steel pipe during rotation and uses shearing force to cut off the steel pipe. The process produces less noise and no debris. However, the shearing depth of this method is shallow, and the existing equipment can only cut one steel pipe at a time, which cannot cut multiple steel pipes at the same time, limiting the efficiency.

[0056] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0057] Please refer to Figures 1-14 A steel pipe cutting machine tool for producing fluid connector processing includes a base 1, the base 1 is provided with a bent material supporting part 2 at both ends, a plurality of shearing sleeves 4 and pushing sleeves 5 are arranged on the two bent material supporting parts 2 respectively, a shearing cutter part 3 is arranged on the base 1 corresponding to the shearing sleeve 4, a slide rail 8 is arranged on the base 1, an electric slide 9 is arranged on the slide rail 8, and the electric slide 9 is arranged at the lower part of the bent material supporting part 2 provided with the pushing sleeve 5;

[0058] As Figure 1As shown, by setting the slide rail 8 and the electric slide block 9, the slide rail 8 and the electric slide block 9 can be driven by electricity to move horizontally in a defined direction, so that they can push the steel pipe by driving the pusher sleeve 5 through the bending material support component 2. The slide rail 8 and the electric slide block 9 are preferably 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 described in detail here.

[0059] The bending support component 2 includes a vertical plate 201 mounted on a base 1 and an electric slide 9. A horizontal plate 202 is fixedly mounted on the vertical plate 201. Multiple hydraulic bending joints 203 are connected in series at both ends of the horizontal plate 202. A support frame 204 connected to a shearing sleeve 4 and a pushing sleeve 5 is mounted on the hydraulic bending joint 203. The hydraulic bending joint 203 includes a hydraulic rotating component 2032. The main body of the hydraulic rotating component 2032 is fixedly connected to the horizontal plate 202 and the adjacent hydraulic bending joint 203. A bearing plate 2031 is fixedly mounted at the output end of the hydraulic rotating component 2032. The bearing plate 2031 is located under the support frame 204. A first bearing component 2033 connected to the adjacent hydraulic bending joint 203 is located at the end of the bearing plate 2031 away from the hydraulic rotating component 2032.

[0060] like Figure 2 As shown, by setting up bending support components 2, there are two bending support components 2. The one corresponding to the shearing cutter component 3 is fixed and used to apply shearing pressure to the steel pipe. The one located on the electric slide 9 is movable and used to push the steel pipe. The two are the same in structure and working mode. When shearing is required, the hydraulic bending joint 203 in the bending support component 2 is in a horizontally unfolded state. Then, multiple steel pipes are placed in the shearing sleeve 4 and the pushing sleeve 5. Subsequently, the hydraulic bending joint 203 starts to fold upward using the internal hydraulic rotating component 2032, so that the steel pipe it carries wraps around the outside of the shearing cutter component 3. Then, the shearing cutter component 3 rotates at high speed, while the hydraulic bending joint 203 continues to bend, applying pressure to the steel pipe, so that the steel pipe is sheared. This achieves the purpose of shearing multiple steel pipes at the same time. While retaining the advantages of the shearing method, it greatly improves the production efficiency. The number of bending joints in series is proportional to the shearing cutter component 3, that is, the larger the size of the shearing cutter, the more bending joints there are.

[0061] The hydraulic rotary assembly 2032 comprises a hydraulic cylinder body 20321 connected with the cross plate 202 and the adjacent hydraulic bending joint 203, the hydraulic cylinder body 20321 is provided with a rotating shaft 20325 fixedly connected with the bearing plate 2031, the rotating shaft 20325 is provided with a gear 20326 located in the hydraulic cylinder body 20321, the side surface of the gear 20326 is engaged with a rack 20324, both ends of the rack 20324 are provided with a piston plate 20322 in sliding sealing cooperation with the inner wall of the hydraulic cylinder body 20321, and the side surface of the hydraulic cylinder body 20321 is provided with an oil passage 20323 in communication with the external hydraulic supply device at the position corresponding to the piston plate 20322;

[0062] As shown in Figure 5 and Figure 6 , by setting the hydraulic rotary assembly 2032, the hydraulic rotary assembly 2032 can convert linear motion into rotary motion by means of the internal rack 20324 and gear 20326, during operation, hydraulic oil is injected into the corresponding position of the hydraulic cylinder body 20321, the hydraulic oil drives the corresponding piston plate 20322 to move, the piston plate 20322 drives the gear 20326 to rotate through the rack 20324, the gear 20326 drives the bearing plate 2031 fixedly connected therewith to rotate through the rotating shaft 20325, and the purpose of bending is achieved, a plurality of hydraulic rotary assemblies 2032 work simultaneously to achieve the effect of surrounding the outside of the shearing tool part 3, and the use of hydraulic drive has better stability and greater driving force, which can meet the pressure requirement during shearing of steel pipes.

[0063] The material receiving frame 204 comprises a hollow frame body 2041 provided on the bearing plate 2031, the hollow frame body 2041 is provided with a positioning groove 2042, and the hollow frame body 2041 is provided with a pressure sensor 2043;

[0064] As shown in Figure 5 , by setting the positioning groove 2042 and the pressure sensor 2043, the positioning groove 2042 can be embedded with the first positioning member 405 and the second positioning member 504, when shearing steel pipes of different sizes, the shearing sleeve 4 and the material pushing sleeve 5 need to be replaced to appropriate specifications, and the positioning groove 2042 can better and quickly align and position, saving the work of positioning and calibration, and 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 part 3, the pressure sensor 2043 can feedback the pressure in real time to judge whether the pressure applied to the steel pipe meets the shearing requirement, so as to ensure that the pressure applied to the steel pipe is consistent, and all the steel pipes can complete the shearing work synchronously.

[0065] The shearing sleeve 4 includes a first cylinder 401, a first connecting plate 404 connected to the hollow frame 2041 at the bottom of the first cylinder 401, a first positioning member 405 fitted into the positioning groove 2042 at the bottom of the first connecting plate 404, a second bearing member 402 inside the first cylinder 401, and a blade groove 403 aligned with the position of the shearing tool component 3 inside the first cylinder 401.

[0066] like Figure 7 As shown, by setting a first cylinder 401 and a second bearing 402, the first cylinder 401 is a through-type structure, which can be sleeved on the steel pipe to achieve the purpose of driving the steel pipe to move. The second bearing 402 is spaced between the first cylinder 401 and the steel pipe, so that the steel pipe rotates more smoothly during shearing and avoids friction between the outer surface of the steel pipe and the inner wall of the first cylinder 401. The blade groove 403 set in the first cylinder 401 does not contact the shearing tool component 3. Its position is aligned with the shearing tool component 3 and only serves to indicate the shearing position.

[0067] The pusher sleeve 5 includes a second cylinder 501. The second cylinder 501 is provided with a second connecting plate 503 connected to the hollow frame 2041. The second connecting plate 503 is provided with a second positioning member 504 that fits into the positioning groove 2042. The second cylinder 501 is provided with a third bearing member 505. The inner wall of the third bearing member 505 is provided with a rubber anti-slip ring 506. The tail end of the second cylinder 501 is provided with an infrared sensor 502.

[0068] like Figure 8 As shown, by setting a second cylinder 501 and a third bearing 505, when the tail end of the second cylinder 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 505 has the same function as the second bearing 402, that is, to support the steel pipe and avoid the problem of friction between the steel pipe and the inner wall of the second cylinder 501. In addition, it should be noted that the inner diameter of the second bearing 402 and the third bearing 505 is slightly larger than the outer diameter of the steel pipe. This method can ensure that the steel pipe can be smoothly inserted into it.

[0069] It should also be noted that a rubber anti-slip ring 506 is provided inside the third bearing component 505. When the steel pipe is inserted into the third bearing component 505, the rubber anti-slip ring 506 will be in close contact with the steel pipe, using friction to fix the steel pipe, so that the steel pipe will not move out of the third bearing component 505 without external force. This avoids the problem of the steel pipe shifting when pushing the steel pipe, which would lead to inconsistent lengths after shearing. The rubber anti-slip ring 506 will rotate with the inner ring of the third bearing component 505, so it will not rub against the outer wall of the steel pipe.

[0070] The shearing blade component 3 includes a fixed frame 301 mounted on the base 1, a drive shaft 303 is provided inside the fixed frame 301, a drive motor 302 is connected to the end face of the drive shaft 303, and a circular shearing blade 304 is provided on the drive shaft 303.

[0071] like Figure 9 As shown, by setting a circular shearing blade 304, which is a high-hardness toothless disc with a circular blade edge on the outermost ring, the blade works by extruding the steel pipe to cut it off. No debris is generated during the process, and the noise is relatively low. In this embodiment, the circular shearing blade 304 is supported and driven by the drive shaft 303 and does not move on its own. During shearing, the bending material-bearing component 2 squeezes the steel pipe toward the circular shearing blade 304. This method also has the advantage of uniform force distribution, avoiding the wear problem of unidirectional force on the drive shaft 303.

[0072] The side of the circular shearing blade 304 is provided with multiple adaptive linkage components 305. The adaptive linkage components 305 are based on the use of friction to drive the steel pipe to rotate when the circular shearing blade 304 rotates.

[0073] The adaptive linkage component 305 includes a fixing plate 3051 disposed on the side of the circular shear blade 304, a slide rod 3052 slidably disposed inside the fixing plate 3051, an arc plate 3054 adapted to the circular edge of the circular shear blade 304 on the slide rod 3052, a first spring 3053 directly disposed between the slide rod 3052 and the fixing plate 3051, and anti-slip stripes 3055 disposed on the arc plate 3054;

[0074] like Figure 10 As shown, by setting a sliding rod 3052 and an arc plate 3054, the arc of the arc plate 3054 fits the outer ring of the circular shearing blade 304. Under normal conditions, it is in the same position as the outer ring of the circular shearing blade 304. When the circular shearing blade 304 rotates, the arc plate 3054 will rotate with it and use its own anti-slip stripes 3055 to drive the steel pipe to rotate, so that the entire circumference of the steel pipe can contact the circular shearing blade 304 and be cut off. In this way, the cutting depth of the circular shearing blade 304 only needs to reach the wall thickness of the steel pipe, which greatly improves the cutting effect. In addition, by driving the steel pipe to rotate, the steel pipe is subjected to uniform force, avoiding the problem of being squeezed and deformed during cutting. Furthermore, the movement of the arc plate 3054 relies entirely on the original rotational movement of the circular shearing blade 304, so there is no need to set up additional drive equipment for the rotation of the steel pipe.

[0075] In addition, the slide rod 3052 is in sliding connection with the fixed plate 3051, so that when the circular cutting knife 304 cuts into the steel pipe, the arc-shaped plate 3054 and the slide rod 3052 can be contracted to the center, thereby avoiding the influence of the arc-shaped plate 3054 on the shearing work of the circular cutting knife 304, and the first spring 3053 supports the slide rod 3052, so that the slide rod 3052 can quickly reset after losing external force.

[0076] One of the fixed plates 3051 is provided with a non-slip powder spraying assembly 306 for increasing the friction between the arc-shaped plate 3054 and the steel pipe, the top end of the non-slip powder spraying assembly 306 penetrates through the arc-shaped plate 3054, and the non-slip powder spraying assembly 306 can be in any posture when the circular cutting knife 304 rotates, and the non-slip powder spraying assembly 306 must be in a vertical upward posture when the circular cutting knife 304 is stationary.

[0077] The non-slip powder spraying assembly 306 comprises a connecting piece 3061 provided on the fixed plate 3051, the connecting piece 3061 is provided with a powder storage tank 3062, the powder storage tank 3062 is slidably provided with a spraying pipe 3064 penetrating through the arc-shaped plate 3054 and fixedly connected with the arc-shaped plate 3054, the spraying pipe 3064 is sleeved with a second spring 3063 connected between the arc-shaped plate 3054 and the powder storage tank 3062, the bottom of the spraying pipe 3064 is provided with a filling port 3066, the powder storage tank 3062 is provided with a groove 3067 embedded with the filling port 3066, and the side of the powder storage tank 3062 is provided with a transparent window 3065.

[0078] As shown in Figure 10 and Figure 11 , by providing the spraying pipe 3064 and the groove 3067, the spraying pipe 3064 is a hollow pipe penetrating from top to bottom, and the bottom is provided with a filling port 3066 corresponding to the groove 3067, 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 and is pressed by the steel pipe, the spraying pipe 3064 will drive the filling 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, and the filling port 3066 will be closed by being fitted with the groove 3067, so that the powder in the storage pipe will not flow into the groove 3067 at this time, and with the rotation of the arc-shaped plate 3054, the powder in the spraying pipe 3064 will be thrown out under the action of centrifugal force, so as to contact the steel pipe on the outside of a circle, increase the friction between the steel pipe and the arc-shaped plate 3054 by the powder, avoid the problem of slipping, and further ensure the stable rotation of the steel pipe. It should be noted that the powder is preferably not dissolved in water and has a hardness lower than that of the steel pipe, so as to prevent the powder from being viscous and difficult to clean, and to avoid the problem of scratching the surface of the steel pipe;

[0079] When the arc plate 3054 is reset, the spray pipe 3064 will be reset simultaneously using the second spring 3063, and the filling port 3066 will separate from the groove 3067. The powder in the powder storage tank 3062 will be automatically replenished into the groove 3067 to wait for subsequent work. No additional driving equipment is required during the implementation process, but the above-mentioned limitations must be followed. In the static state, the anti-slip powder spraying component 306 must be vertically upward.

[0080] The base 1 is equipped with a pre-support component 6 that is flush with the shearing sleeve 4 and the pusher sleeve 5;

[0081] The pre-support component 6 includes a support shaft 603 located in the base 1, a support plate 602 fixedly mounted on the support shaft 603, a first reduction motor 601 connected to the side of the support shaft 603, a support plate 604 mounted on the support plate 602, and a material trough 605 for placing steel pipes mounted on the support plate 604.
