DETAILED DESCRIPTION

[0021] 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.

[0022] Reference Figure 1-Figure 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; 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. 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; 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. The specific operating steps of the stainless steel pipe slitting machine are as follows: 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; Step 2: Cutting, the cross bar 2 synchronously drives the multiple clamping components to rotate counterclockwise, and transfers the pipe 101 to the slitting component. In this embodiment, multiple slitting components are set, and the multiple slitting components are performed synchronously. Specifically, a driving component for driving the slider 7 is provided on the base plate 6. The driving component can be composed of a screw and a driving motor 10. The output end of the driving motor 10 is connected to the screw, and the screw is connected to the slider 7, which can drive the slider 7 to move on the base plate 6. When the pipe 101 is transferred to the side of the cutting disk 8, the cross bar 2 stops rotating. At the same time, the cutting motor drives the cutting disk 8 to rotate at high speed. The slider 7 drives the cutting motor to approach the pipe 101 and cuts a plurality of shorter pipes 101 from a longer pipe 101, thereby realizing multi-segment slitting of the pipe 101. Step 3: Unloading. After the slitting is completed, the slider 7 drives the cutting motor to withdraw away from the pipe 101. The crossbar 2 drives the cut pipe 101 to the position below the crossbar 2 through the clamping assembly. The operating table 1 is provided with a discharge port 11. The pipe 101 is transferred to the discharge port 11 position. Then, the clamping assembly releases the pipe 101, and the pipe 101 is unloaded. Then repeat steps one, two and three; the stainless steel pipe slitting machine, first, in terms of loading, the pipes 101 can be installed on the rotating unit one by one, and the intermittent rotation of the rotating unit can realize the loading and standby of multiple pipes 101, then, in terms of cutting, the cutting link and the loading link do not interfere with each other, loading can also be carried out during the cutting process, and multiple slitting components are provided, which can cut the pipe 101 at multiple positions at the same time, and cut the longer pipe 101 into multiple shorter pipes 101 at one time, doubling the efficiency, eliminating the link of secondary adjustment of the position of the pipe 101 in the middle, and secondly, in terms of unloading, the loading link, cutting link and unloading link are executed separately, and the three links do not interfere with each other. After unloading is completed, the loading link can be carried out, thereby improving the overall processing efficiency of stainless steel pipe slitting.

[0023] Reference Figure 4-Figure 8 Each of the clamping components includes a motor 12 fixed to the outer ring of the cross bar 2, the cross bar 2 of each motor 12 is arranged along the length direction of the support rod 4 in each group, the output end of each motor 12 extends to one side of the ring body 5, and a base shell 13 is provided at the output end of each motor 12, the outer side of the base shell 13 is fixed to the ring body 5, a gear 14 is provided at the center position of the base shell 13, the end face of the gear 14 passes through the base shell 13 and is fixed to the output end of the motor 12, racks 15 are provided on both sides of the gear 14, and the two racks 15 are symmetrically arranged. A clamping claw 16 is connected to one side of each rack 15, and the clamping claw 16 extends to the outside of the base shell 13; In the embodiment of the present invention, the clamping assembly is designed to be an electrically driven clamping jaw 16. The specific operation of the clamping jaw 16 is as follows: the motor 12 is controlled by a PLC. When the pipe 101 is placed in two adjacent clamping jaws 16, the PLC controls the motor 12 to rotate, and the motor 12 drives the gear 14 to rotate. The gear 14 drives the two adjacent racks 15 to slide in the base shell 13. The racks 15 drive the clamping jaws 16 thereon to each other and wrap around the outer surface of the pipe 101. The specific shape of the clamping jaw 16 is as follows: Figure 6 and Figure 8 As shown, the effective clamping portion of the clamping jaws 16 is in an arc shape, which can effectively wrap the pipe 101; When the clamping jaws 16 release the cut tube 101, the motor 12 drives the gear 14 to reverse, and the two adjacent clamping jaws 16 move away from each other. The tube 101 loses the clamping of the clamping jaws 16 and falls away from the slitting machine along the discharge port 11 under its own gravity.

[0024] Reference Figure 1-Figure 3 A positioning assembly is provided at the end of the rotating unit. The positioning assembly includes a vertical plate 17 fixed to one of the support frames 3 and a support plate 18 fixed to the other support frame 3. A hydraulic rod 19 is fixed to the support plate 18. The output end of the hydraulic rod 19 points to the vertical plate 17 and is fixed to a push plate 20. The push plate 20 is used to push the pipe 101 toward the vertical plate 17. Taking into account the position of the tube 101 and each cutting component during the loading process, there is a problem that waste will be generated at both ends of the tube 101. For this purpose, a positioning component is provided to reduce the generation of waste at one end of the tube 101. Specifically, when the rotating unit transfers the tube 101 to its top position, the rotating unit pauses and then drives the No. 1 hydraulic rod 19. The No. 1 hydraulic rod 19 drives the push plate 20 to press against one end of the tube 101. The tube 101 slides in the multiple clamps 16, and the other end of the tube 101 presses against the vertical plate 17. At this time, each tube 101 passing through the top of the rotating unit is squeezed and positioned by the push plate 20, and the other ends of all the tubes 101 are squeezed to the same position, thereby reducing the generation of waste of the tube 101. Considering that the No. 1 hydraulic rod 19 can adapt to the extrusion of different pipes 101, a pressure sensor 21 can be set on the vertical plate 17. The pressure sensor 21 controls the output of the output end of the No. 1 hydraulic rod 19 through the PLC. The contact surface of the pressure sensor 21 is opposite to the other end of the pipe 101. When the push plate 20 squeezes the pipe 101, the other end of the pipe 101 presses against the pressure sensor 21. When the pressure sensor 21 receives a preset pressure value, the PLC controls the output end of the No. 1 hydraulic rod 19 to pause. At this time, each pipe 101 of different lengths can be stably squeezed on the vertical plate 17, so as to prevent the output end of the No. 1 hydraulic rod 19 from continuously and rigidly squeezing the pipe 101 and causing serious processing accidents. After the push plate 20 finishes squeezing the pipe 101 , the No. 1 hydraulic rod 19 drives the push plate 20 to retreat and reset, preparing for the positioning of the next pipe 101 .

[0025] Reference Figure 6 , a plurality of rotation grooves are opened on the inner side wall of each clamping jaw 16, and a ball 22 is rotatably connected in each rotation groove; There is friction between the clamping jaws 16 and the tube 101. When the push plate 20 pushes the tube 101 to move along the multiple clamping jaws 16, the smoothness of the movement of the tube 101 needs to be considered. For this purpose, a ball 22 is provided on the inner wall of the clamping jaw 16 to convert the sliding friction between the tube 101 and the clamping jaw 16 into rolling friction between the tube 101 and the ball 22, thereby reducing the resistance of the tube 101 during positioning and movement, so that it can move smoothly.

[0026] Reference Figure 6-Figure 9 Each of the clamping jaws 16 is rotationally connected to the rack 15, and a torsion spring is provided at the rotation connection point, and the torsion force of the torsion spring is used to twist the clamping jaw 16 to clamp the pipe 101; The clamping jaws 16 are assembled on the rack 15 by means of a rotational connection, so that the clamping jaws 16 can elastically clamp the pipe 101 and are suitable for clamping pipes 101 with different diameters. In this embodiment, the motor 12 can also be controlled by PLC to drive the rotation angle of the gear 14 to realize the movement stroke of the rack 15. However, when clamping pipes 101 of different diameters, different programs need to be set to control the rotation angle of the gear 14. The program is relatively cumbersome, and the switching program is also relatively troublesome. Moreover, there are also errors in the switching of programs. For this reason, in this embodiment, it is preferred to clamp pipes 101 of different diameters by mechanical means. Specifically, the gear 14 rubs the rack 15 to move, and the rack 15 drives the clamping jaws 16 to move. When the clamping jaws 16 clamp the pipe 101 with a smaller diameter, the clamping force of the clamping jaws 16 on the pipe 101 is still within the expected range through the torsion of the torsion spring. When the clamping jaws 16 clamp the pipe 101 with a larger diameter, the effective clamping part on the clamping jaws 16 can still wrap and clamp the pipe 101.

[0027] Reference Figure 6-Figure 8 A limit switch 23 is provided on the inner side wall of each base shell 13, and the limit switch 23 is provided at a position opposite to the end of the rack 15, and the limit switch 23 is used to control the rotation pause of the motor 12; The limit switch 23 is used to control the rotation pause of the motor 12 and further control the movement stroke of the rack 15. Specifically, when the movement stroke of the rack 15 is too large, the torsion angle of the torsion spring will be too large, which will affect the elastic deformation of the torsion spring. For this reason, a limit switch 23 is set in the base block. When the movement stroke of the rack 15 reaches its limit value, the end of the rack 15 will press against the limit switch 23. The limit switch 23 controls the motor 12 to pause through the PLC and stops the rotation of the gear 14, thereby controlling the continuous movement of the rack 15, and then controlling the deflection angle of the two adjacent jaws 16 to protect the torsion spring, so that the torsion spring can provide torque to the jaw 16 for a long time and effectively.

[0028] Reference Figure 1-Figure 2 ,as well as Figure 10 The lower surfaces of the multiple substrates 6 are slidably connected to a guide plate 24, and a guide groove 25 is provided on the guide plate 24. The slider 7 provided on the lower surface of the substrate 6 is slidably connected in the guide groove 25, and each guide groove 25 is provided with an electric push rod for driving the slider 7 to move; The electric push rod is used to push or pull the position of the substrate 6 on the guide plate 24, thereby adjusting the distance between two adjacent cutting components. It can cut different parts of the tube 101, and a longer tube 101 can be cut into shorter tubes 101 of different lengths. It has high flexibility and applicability to meet different production needs.

[0029] Reference Figure 1-Figure 2 ,as well as Figure 10 , a channel 26 is provided inside the substrate 6, one end of the channel 26 passes through one side of the substrate 6 and is connected to the liquid supply pipe 27, the other end of the channel 26 passes vertically upward through the upper surface of the substrate 6, and a slide plate 28 is sealed and slidably connected to the upper surface of the substrate 6, the slide plate 28 is fixed to the slider 7, a through hole 29 is provided on the slide plate 28, and a liquid infusion pipe 30 is connected at the position of the through hole 29, and the outlet end of the liquid infusion pipe 30 extends to one side of the cutting disk 8; the lower hole end of the through hole 29 is in a strip shape, which can increase the connection time between the through hole 29 and the other end of the channel 26; When the pipe 101 is cut, the coolant needs to be replenished to cool and protect the cutting disc 8. Since the cutting disc 8 continuously cuts the pipe 101, in order to prevent the cutting disc 8 from being damaged by overheating, a structure that can replenish the coolant in time is provided in this embodiment. Specifically, the liquid supply pipe 27 is connected to the external liquid pump, and the liquid pump injects the coolant into the channel 26; in the initial state, the through hole 29 on the slide 28 is staggered and separated from the other end of the channel 26, and the lower surface of the slide 28 seals and covers the other end of the channel 26 to block it. When the slider 7 moves along the surface of the substrate 6 During movement, the slider 7 drives the slide plate 28 to move. At this time, the through hole 29 on the slide plate 28 is opposite to the other end of the channel 26. The coolant flows along the channel 26 and the through hole 29 and is discharged from the liquid infusion tube 30. The coolant is sprayed on the cutting disc 8 and the pipe 101. At the same time, the cutting disc 8 cuts the pipe 101. The shape of the lower hole 29 can increase the communication time between the through hole 29 and the other end of the channel 26. When the cutting disc 8 moves forward, the through hole 29 can always be connected with the other end of the channel 26, and the coolant is continuously sprayed. After the pipe 101 is cut, the slide plate 28 is retracted and reset along with the slider 7, and the slide plate 28 covers and seals the other end of the channel 26 again, thereby realizing intermittent supply of coolant to avoid waste of coolant.

[0030] Reference Figure 1-Figure 2 A loading assembly is provided on the other side of the operating table 1. The loading assembly includes a plurality of conveyor belts 31 spaced at equal distances. A plurality of partitions 32 are provided on each conveyor belt 31. A pipe 101 is placed on the partition 32 at the same position of each conveyor belt 31. A plurality of second hydraulic rods 33 are obliquely provided below the conveyor belt 31 , and an arc-shaped support plate 34 is fixedly connected to the output end of each second hydraulic rod 33 . The support plate 34 is used to push the pipe 101 on the conveyor belt 31 into the clamping jaw 16 ; The provided loading assembly is used to automatically load the pipe 101 onto the clamping jaws 16. Specifically, the operator only needs to place the pipe 101 on the conveyor belt 31 and between the partitions 32 in each group. The subsequent conveyor belt 31 then intermittently transmits the pipe 101 and cooperates with the intermittently rotating rotating unit. When the pipe 101 is conveyed to the end position of the conveyor belt 31, the rotating unit and the conveyor belt 31 are paused, and then the No. 2 hydraulic rod 33 drives the support plate 34, and the support plate 34 tilts to load the pipe 101 and push the pipe 101 into the clamping jaws 16. After the clamping jaws 16 clamp the pipe 101, the No. 2 hydraulic rod 33 drives the support plate 34 to retreat and reset, and the rotating unit and the conveyor belt 31 start again, and the above actions are repeated subsequently. In order to improve the accuracy of the feeding position of the pipe 101, a guide plate 35 can be set on one side of the conveyor belt 31 at the end. Figure 1As shown, when the end of the tube 101 is pressed against the arc-shaped portion of the guide plate 35, the guide plate 35 squeezes the tube 101, and the position of the tube 101 is adjusted on the conveyor belt 31, so that the other end of the tube 101 tends to be aligned, reducing the pressure of the subsequent positioning assembly on the positioning and calibration of the tube 101.

[0031] Reference Figure 8 and Figure 9 , a guide rod 36 passes through the end of each rack 15, and the end of the guide rod 36 is fixed to the inner wall of the base shell 13; The guide rod 36 is used 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, ensuring that the clamping jaws 16 can stably clamp the pipe 101.

[0032] Working principle: Step 1: Loading: At 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; Step 2: Cutting, the cross bar 2 synchronously drives the multiple clamping components to rotate counterclockwise, and transfers the pipe 101 to the slitting component. In this embodiment, multiple slitting components are set, and the multiple slitting components are performed synchronously. Specifically, a driving component for driving the slider 7 is provided on the base plate 6. The driving component can be composed of a screw and a driving motor 10. The output end of the driving motor 10 is connected to the screw, and the screw is connected to the slider 7, which can drive the slider 7 to move on the base plate 6. When the pipe 101 is transferred to the side of the cutting disk 8, the cross bar 2 stops rotating. At the same time, the cutting motor drives the cutting disk 8 to rotate at high speed. The slider 7 drives the cutting motor to approach the pipe 101 and cuts a plurality of shorter pipes 101 from a longer pipe 101, thereby realizing multi-segment slitting of the pipe 101. Step 3: Unloading. After the cutting is completed, the slider 7 drives the cutting motor to retreat away from the pipe 101. The cross bar 2 drives the cut pipe 101 to be transferred to the lower position of the cross bar 2 through the clamping assembly. The unloading port 11 is opened on the operating table 1. The pipe 101 is transferred to the unloading port 11 position, and then the clamping assembly releases the pipe 101. The pipe 101 is unloaded; then repeat steps 1, 2 and 3.
