DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Reference Figures 1-5 ,as well as Figure 10 A stainless steel pipe slitting machine includes an operating table 1, a rotating unit is provided in the middle of the operating table 1, a plurality of clamping components for clamping a pipe 101 are provided on the rotating unit, and a plurality of slitting components are provided on one side of the operating table 1;

[0036] The rotating unit includes a crossbar 2 whose axis is horizontally placed on the operating table 1. Both ends of the crossbar 2 are rotatably connected to support frames 3, which are fixed to the operating table 1. Multiple groups of support rods 4 are radially arranged on the outer ring of the crossbar 2. The end of each group of support rods 4 is fixedly connected to a ring body 5. A clamping assembly is provided between one side of the ring body 5 and the outer ring of the crossbar 2.

[0037] The slitting assembly includes a base plate 6 arranged on the operating table 1, a slider 7 is slidably connected to the base plate 6, a cutting motor is arranged on the slider 7, and a cutting disc 8 is fixedly connected to the output end of the cutting motor;

[0038] In the embodiment of the present invention, the end of the crossbar 2 is rotatably connected to the support frame 3, and a reduction motor 9 is provided at the end of the crossbar 2 to drive the rotation thereof. The reduction motor 9 is controlled by a PLC and can realize intermittent rotation of the crossbar 2.

[0039] The specific operating steps of the stainless steel pipe slitting machine are as follows:

[0040] Step 1: Loading: On the other side of the operating table 1, while the crossbar 2 is paused, place the pipe 101 on the clamping assembly, and the clamping assembly clamps the pipe 101;

[0041] Step two: cutting, the horizontal rod 2 drives the plurality of clamping assemblies to rotate counterclockwise, and the pipe 101 is transferred to the cutting assembly below. In this embodiment, a plurality of cutting assemblies are provided, and the plurality of cutting assemblies are synchronized. Specifically, the base plate 6 is provided with a driving assembly for driving the sliding block 7. The driving assembly can be composed of a lead screw and a driving motor 10. The output end of the driving motor 10 is connected to the lead screw, the lead screw is connected to the sliding block 7, and the sliding block 7 can be driven to move on the base plate 6. When the pipe 101 is transferred to the side of the cutting disc 8, the horizontal rod 2 stops rotating, the cutting motor drives the cutting disc 8 to rotate at high speed, the sliding block 7 drives the cutting motor to approach the pipe 101, and a plurality of shorter pipes 101 are cut from a longer pipe 101, realizing multi-section cutting of the pipe 101;

[0042] Step three: discharging. After cutting, the sliding block 7 drives the cutting motor to retreat away from the pipe 101, the horizontal rod 2 drives the cut pipe 101 to the position below the horizontal rod 2 through the clamping assembly, a discharge port 11 is formed on the operation table 1, the pipe 101 is transferred to the discharge port 11, and then the clamping assembly releases the pipe 101, and the pipe 101 is discharged;

[0043] After that, steps one, two and three can be repeated. The stainless steel pipe cutting machine can first install the pipes 101 on the rotating unit one by one, and the intermittent rotation of the rotating unit can realize the feeding of a plurality of pipes 101 for standby. Then, in the cutting aspect, the cutting link and the feeding link do not interfere with each other. During the cutting process, feeding can also be performed. The cutting assembly is provided with a plurality of cutting assemblies, which can simultaneously cut the pipe 101 at multiple positions, thereby doubling the efficiency and eliminating the intermediate step of adjusting and placing the pipe 101. Secondly, in the discharging aspect, the feeding link, the cutting link and the discharging link are executed respectively, and the three links do not interfere with each other. After discharging, the feeding link can be performed, thereby improving the overall processing efficiency of the stainless steel pipe cutting.

[0044] Referring to Figures 4-8 Each of the clamping assemblies comprises a motor 12 fixed to the outer ring of the horizontal rod 2. The output end of each motor 12 extends to one side of the ring body 5, and the output end of each motor 12 is provided with a base shell 13. The outer side of the base shell 13 is fixed to the ring body 5, the center of the inside of the base shell 13 is provided with a gear 14, the end face of the gear 14 penetrates the base shell 13 and is fixed to the output end of the motor 12, and the two sides of the gear 14 are provided with a rack 15. The two racks 15 are symmetrically arranged at the center, one side of each rack 15 is connected with a clamping jaw 16, and the clamping jaw 16 extends to the outside of the base shell 13.

[0045] In the embodiment of the present application, the designed clamping assembly is an electrically driven clamping jaw 16. The specific operation of the clamping jaw 16 is as follows. The motor 12 is controlled by the PLC. When the pipe 101 is placed in the adjacent two clamping jaws 16, the PLC controls the motor 12 to rotate. The motor 12 drives the gear 14 to rotate. The gear 14 drives the adjacent two racks 15 to slide in the base shell 13. The racks 15 drive the clamping jaws 16 on them to each other and wrap the outer surface of the pipe 101. The specific shape of the clamping jaw 16 is as shown in Figure 6 and Figure 8 The effective clamping part of the clamping jaw 16 is in an arc shape, which can effectively wrap the pipe 101.

[0046] When the clamping jaw 16 releases the cut pipe 101, the motor 12 drives the gear 14 to reverse. The adjacent two clamping jaws 16 move away from each other. The pipe 101 loses the clamping of the clamping jaw 16. The pipe 101 falls away from the cutting machine under its own gravity along the discharge port 11.

[0047] Referring to Figures 1-3 , the end of the rotating unit is provided with a positioning assembly. The positioning assembly includes a vertical plate 17 fixed on one of the support frames 3 and a support plate 18 fixed on the other support frame 3. The support plate 18 is fixedly connected with a first hydraulic rod 19. The output end of the first hydraulic rod 19 points to the vertical plate 17 and is fixedly connected with a push plate 20. The push plate 20 is used to push the pipe 101 to the vertical plate 17.

[0048] Considering the position of the pipe 101 on each cutting assembly during the feeding process, the ends of the pipe 101 will generate waste. Therefore, the positioning assembly is provided to reduce the generation of waste at one end of the pipe 101. Specifically, when the rotating unit transfers the pipe 101 to the top position, the rotating unit pauses and then drives the first hydraulic rod 19. The first hydraulic rod 19 drives the push plate 20 to abut against one end of the pipe 101. The pipe 101 slides in the multiple clamping jaws 16. The other end of the pipe 101 abuts against the vertical plate 17. At this time, each pipe 101 passing through the top of the rotating unit is positioned by the extrusion of the push plate 20. The other end of all pipes 101 is extruded to the same position, thereby reducing the generation of waste of the pipe 101.

[0049] Considering that the first hydraulic rod 19 can be adapted to different pipe materials 101 extrusion, a pressure sensor 21 can be arranged on the vertical plate 17, the pressure sensor 21 is output by the PLC control first hydraulic rod 19 output end, the contact surface of the pressure sensor 21 is opposite to the other end of the pipe material 101, when the push plate 20 extrudes the pipe material 101, the other end of the pipe material 101 is pressed on the pressure sensor 21, when the pressure sensor 21 is subjected to a preset pressure value, the PLC controls the first hydraulic rod 19 output end to pause, at this time, each pipe material 101 of different length can be stably extruded on the vertical plate 17, so as to avoid that the first hydraulic rod 19 output end continuously extrudes the pipe material 101, causing serious processing accident;

[0050] After the push plate 20 extrudes the pipe material 101, the first hydraulic rod 19 drives the push plate 20 to retreat and reset, preparing for the positioning of the next pipe material 101.

[0051] With reference to Figure 6 Each of the inside walls of the clamping jaws 16 is provided with a plurality of rotating grooves, and each rotating groove is rotatably connected with a ball 22;

[0052] There is friction between the clamping jaw 16 and the pipe material 101, when the push plate 20 pushes the pipe material 101 to move along the plurality of clamping jaws 16, the smoothness of the pipe material 101 movement needs to be considered, for this purpose, the ball 22 is arranged on the inside wall of the clamping jaw 16, the sliding friction between the pipe material 101 and the clamping jaw 16 is converted into the rolling friction between the pipe material 101 and the ball 22, the resistance of the pipe material 101 positioning and moving is reduced, so that it can move smoothly.

[0053] With reference to Figures 6-9 Each of the clamping jaws 16 is rotatably connected with the rack 15, and a torsional spring is arranged at the rotation connection point, the torsional force of the torsional spring is used to twist the clamping jaw 16 to clamp the pipe material 101;

[0054] The clamping jaw 16 is assembled on the rack 15 in a rotatable manner, realizing the elastic clamping of the pipe material 101 by the clamping jaw 16, and being suitable for clamping pipe materials 101 with different diameters;

[0055] In this embodiment, the motor 12 can also be controlled by PLC to drive the gear 14 to rotate to a certain angle to achieve the moving stroke of the rack 15. However, for clamping pipe materials 101 with different diameters, different programs need to be set to control the rotating angle of the gear 14, and the program is relatively complicated. Meanwhile, it is relatively troublesome to switch the program. In addition, the switching of the program may also be wrong. Therefore, in this embodiment, a mechanical method is preferably used to clamp pipe materials 101 with different diameters. Specifically, the gear 14 drives the rack 15 to move, and the rack 15 drives the clamping jaw 16 to move. When the clamping jaw 16 clamps the pipe material 101 with a smaller diameter, the clamping force of the pipe material 101 by the clamping jaw 16 through the torsional force of the torsional spring is still within the expected range. When the clamping jaw 16 clamps the pipe material 101 with a larger diameter, the effective clamping part of the clamping jaw 16 can still wrap and clamp the pipe material 101.

[0056] With reference to Figures 6-8 A limit switch 23 is arranged on the inner side wall of each base shell 13, and the limit switch 23 is arranged at a position opposite to the end of the rack 15. The limit switch 23 is used to control the rotation of the motor 12 to pause.

[0057] The limit switch 23 is arranged to control the rotation of the motor 12 to pause, and further control the moving stroke of the rack 15. Specifically, when the moving stroke of the rack 15 is too large, the torsional angle of the torsional spring will be too large, which will affect the elastic deformation of the torsional spring. Therefore, the limit switch 23 is arranged in the base block. When the moving stroke of the rack 15 reaches the limit value, the end of the rack 15 will abut against the limit switch 23. The limit switch 23 controls the motor 12 to pause through PLC, and stops the rotation of the gear 14, thereby controlling the continuous movement of the rack 15, and further controlling the deflection angle of the adjacent two clamping jaws 16, protecting the torsional spring, and enabling the torsional spring to provide the torsional force to the clamping jaw 16 for a long time and effectively.

[0058] With reference to Figures 1-2 And Figure 10 A plurality of guide plates 24 are slidably connected to the lower surfaces of the plurality of base plates 6. Guide grooves 25 are formed in the guide plates 24. The sliding blocks 7 arranged on the lower surfaces of the base plates 6 are slidably connected in the guide grooves 25. An electric push rod is arranged in each guide groove 25 to drive the sliding block 7 to move.

[0059] The electric push rod is used to push or pull the base plate 6 on the guide plate 24 to adjust the distance between the adjacent two slitting assemblies, so that the pipe material 101 can be cut at different positions. One long pipe material 101 can be cut into pipe materials 101 with different lengths, which has high flexibility and applicability, and can meet different production needs.

[0060] With reference to Figures 1-2 And Figure 10The substrate 6 is internally provided with a channel 26, one end of the channel 26 penetrates one side of the substrate 6 and communicates with a liquid supply pipe 27, and the other end of the channel 26 penetrates the upper surface of the substrate 6 vertically upward, and the upper surface of the substrate 6 is sealingly connected with a sliding plate 28 in a sliding manner, the sliding plate 28 is fixedly connected with the sliding block 7, a through hole 29 is formed in the sliding plate 28, the through hole 29 is in communication with a liquid supplement pipe 30, and the outlet end of the liquid supplement pipe 30 extends to one side of the cutting disc 8; the lower hole end of the through hole 29 is in a strip shape, which can increase the communication time length of the through hole 29 and the other end of the channel 26;

[0061] When the pipe material 101 is cut, the cooling liquid needs to be supplemented to protect the cutting disc 8, and the cutting disc 8 continuously cuts the pipe material 101 to prevent the cutting disc 8 from being damaged due to overheating. Therefore, the structure for supplementing the cooling liquid in time is arranged in the embodiment, specifically, the liquid supply pipe 27 is connected with an external liquid pump, and the liquid pump injects the cooling liquid into the channel 26; in the initial state, the through hole 29 on the sliding plate 28 is staggered and separated from the other end of the channel 26, and the lower surface of the sliding plate 28 sealingly covers the other end of the channel 26 to block it; when the sliding block 7 moves along the surface of the substrate 6, the sliding block 7 drives the sliding plate 28 to move, at this time, the through hole 29 on the sliding plate 28 is opposite to the other end of the channel 26, the cooling liquid flows along the channel 26 and the through hole 29, and is discharged from the liquid supplement pipe 30, and the cooling liquid is sprayed on the cutting disc 8 and the pipe material 101, and the cutting disc 8 cuts the pipe material 101; the lower hole of the through hole 29 is in a shape, which can increase the communication time length of the through hole 29 and the other end of the channel 26; during the advancing process of the cutting disc 8, the through hole 29 can always be in communication with the other end of the channel 26, and the cooling liquid is continuously sprayed;

[0062] When the pipe material 101 is cut, the cooling liquid needs to be supplemented to protect the cutting disc 8, and the cutting disc 8 continuously cuts the pipe material 101 to prevent the cutting disc 8 from being damaged due to overheating. Therefore, the structure for supplementing the cooling liquid in time is arranged in the embodiment, specifically, the liquid supply pipe 27 is connected with an external liquid pump, and the liquid pump injects the cooling liquid into the channel 26; in the initial state, the through hole 29 on the sliding plate 28 is staggered and separated from the other end of the channel 26, and the lower surface of the sliding plate 28 sealingly covers the other end of the channel 26 to block it; when the sliding block 7 moves along the surface of the substrate 6, the sliding block 7 drives the sliding plate 28 to move, at this time, the through hole 29 on the sliding plate 28 is opposite to the other end of the channel 26, the cooling liquid flows along the channel 26 and the through hole 29, and is discharged from the liquid supplement pipe 30, and the cooling liquid is sprayed on the cutting disc 8 and the pipe material 101, and the cutting disc 8 cuts the pipe material 101; the lower hole of the through hole 29 is in a shape, which can increase the communication time length of the through hole 29 and the other end of the channel 26; during the advancing process of the cutting disc 8, the through hole 29 can always be in communication with the other end of the channel 26, and the cooling liquid is continuously sprayed;

[0063] Referring to Figures 1-2 The other side of the operation table 1 is provided with a feeding assembly, the feeding assembly comprises a plurality of conveying belts 31 which are arranged at the same distance, a plurality of groups of partition plates 32 are arranged on each conveying belt 31, and one pipe material 101 is placed on the partition plates 32 at the same position of each conveying belt 31;

[0064] A plurality of second hydraulic rods 33 are arranged inclined below the conveying belt 31, the output end of each second hydraulic rod 33 is fixedly connected with an arc-shaped supporting plate 34, and the supporting plate 34 is used for pushing the pipe material 101 on the conveying belt 31 into the clamping jaw 16;

[0065] The feeding assembly is arranged to automatically feed the pipe 101 to the clamping jaw 16. Specifically, the operator only needs to place the pipe 101 on the conveying belt 31 and between the partitions 32 in each group. Then, the conveying belt 31 intermittently drives the pipe 101, and the rotating unit rotates intermittently. When the pipe 101 is conveyed to the end position of the conveying belt 31, the rotating unit and the conveying belt 31 are paused. Then, the second hydraulic rod 33 drives the supporting plate 34 to tilt and support the pipe 101, and push the pipe 101 into the clamping jaw 16. After the clamping jaw 16 clamps the pipe 101, the second hydraulic rod 33 drives the supporting plate 34 to retreat and reset. The rotating unit and the conveying belt 31 operate again, and the above-mentioned action is repeated.

[0066] In order to improve the accuracy of the feeding position of the pipe 101, a guide plate 35 is arranged on one side of the conveying belt 31 at the end. As shown in Figure 1 When the end of the pipe 101 is on the arc-shaped part of the guide plate 35, the guide plate 35 presses the pipe 101, and the pipe 101 is adjusted in position on the conveying belt 31, so that the other end of the pipe 101 tends to be aligned, reducing the pressure of the subsequent positioning assembly on the pipe 101.

[0067] Referring to Figure 8 and Figure 9 The guide rod 36 is arranged at the end of each rack 15 and is fixed to the inner side wall of the base shell 13.

[0068] The guide rod 36 is arranged to guide the movement of the rack 15 and limit the deflection of the rack 15 in the base shell 13, so that the rack 15 can stably move in a straight line, and the clamping jaw 16 can stably clamp the pipe 101.

[0069] Working principle: step one: feeding, at the other side of the operation table 1, during the pause of the rotation of the horizontal rod 2, the pipe 101 is placed on the clamping assembly, and the clamping assembly clamps the pipe 101.

[0070] Step two: cutting, the horizontal rod 2 synchronously drives the plurality of clamping assemblies to rotate counterclockwise, and the pipe 101 is transferred to the cutting assembly. In this embodiment, a plurality of cutting assemblies are arranged and synchronously operated. Specifically, the base plate 6 is provided with a driving assembly for driving the sliding block 7.
