Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a stainless steel cutting device. Background Technology

[0002] In modern manufacturing, stainless steel pipes are widely used in many fields such as petrochemicals, building decoration, food, and medicine due to their excellent corrosion resistance, high strength, and good processing performance. With the acceleration of industrialization, enterprises have placed higher demands on the efficiency and automation of stainless steel pipe cutting.

[0003] According to a cutting device disclosed in Chinese Patent Publication No. CN118023599B, ​​the device includes a feeding platform, an auxiliary feeding assembly, and a cutting assembly. The feeding platform includes a separation zone and a cutting zone. The auxiliary feeding assembly is used to transport workpieces from the separation zone to the cutting zone. The cutting assembly is located in the cutting zone and is used to cut the workpieces. The auxiliary feeding assembly includes two sets of auxiliary feeding rollers, a separation blade, and an adjusting blade. The two sets of auxiliary feeding rollers are disposed on both sides of the separation zone and both sides of the cutting zone. The separation blade is spirally disposed on the auxiliary feeding roller in the separation zone and is used to transport the workpiece. The adjusting blade is spirally disposed at the output end of the separation blade and is located on the auxiliary feeding roller in the cutting zone. It is used to adjust the posture of the workpiece during transport to assist the cutting assembly in cutting the workpiece. The rotation of the auxiliary feeding roller drives the separation blade to separate and transport the workpiece in the separation zone, and drives the adjusting blade to transport and change the posture of the workpiece in the cutting zone. This enables the workpieces to be separated one by one, facilitating the cutting assembly to cut the workpieces.

[0004] The aforementioned patent can continuously feed and cut steel plates, but it cannot continuously feed tubular workpieces, thus affecting the processing efficiency of stainless steel pipes. Therefore, a stainless steel cutting device is proposed to solve the aforementioned problem. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] The present invention, by adopting the above technical solution, can bring the following beneficial effects: A stainless steel cutting device, including a base, and further comprising:

[0008] A cutting assembly, located above the base, is used to cut stainless steel pipes;

[0009] A collection box, located above the base, is used to collect the stainless steel pipes after they have been cut.

[0010] The top of the base is fixedly connected to a first bracket, and a motor slide rail is fixedly connected to the first bracket. Two linear motors are installed on the motor slide rail, and a cutting machine is installed at the bottom of the linear motors. The stainless steel pipe is cut by the cutting machine.

[0011] The cutting machine is provided with a feeding mechanism below it, which includes a motor, a second bracket, a first horizontal shaft, a wheel, and a slot.

[0012] The motor is fixedly connected to the back of the first bracket, and the second bracket is fixedly connected to the top of the base. The rear end of the first horizontal shaft passes through the first bracket via a bearing and is fixedly connected to the front output end of the motor. The front end of the first horizontal shaft passes through the second bracket via a bearing. A wheel is fixedly connected to the middle of the first horizontal shaft. Several slots are provided on the wheel. The several slots are rotatably arranged around the central axis of the first horizontal shaft. The slots limit the movement of the stainless steel tube.

[0013] Preferably, a telescopic rod is fixedly connected to the top of the base, a feeding ramp is fixedly connected to the top of the telescopic rod, a spring is sleeved on the outside of the telescopic rod, the top of the spring is fixedly connected to the feeding ramp, the bottom of the spring is fixedly connected to the base, a cam is fixedly connected to the middle of the first horizontal shaft, the cam is located in front of the second bracket, and a movable plate is fixedly connected to the bottom of the feeding ramp through a connecting rod. The top of the movable plate contacts the cam, and the movable plate is pressed down by rotating the cam.

[0014] Preferably, a rolling mechanism is provided on the right side of the wheel. The rolling mechanism includes two vertical rods, which are fixedly connected to the top of the base. A second horizontal shaft is rotatably passed between the two vertical rods through a bearing. A pressure roller is fixedly connected to the middle of the second horizontal shaft. The pressure roller is located at the upper right corner of the wheel. The pressure roller rolls the surface of the stainless steel tube to release its internal residual stress.

[0015] Preferably, a gear is fixedly connected to the front end of the second horizontal shaft, and a disk is fixedly connected to the front end of the first horizontal shaft. Multiple sets of transmission teeth are arranged in an array on the outer side of the disk, and the transmission teeth mesh with the gear.

[0016] Preferably, a torsion spring is sleeved on the outside of the second horizontal shaft. The rear end of the torsion spring is fixedly connected to the vertical rod, and the front end of the torsion spring is fixedly connected to the back of the pressure roller. The pressure roller is reversed by the torsion spring.

[0017] Preferably, a vibration mechanism is provided below the pressure roller. The vibration mechanism includes two first sliding grooves, which are respectively opened through the two vertical rods. A first slider is slidably connected inside the first sliding groove. A discharge plate is fixedly connected between the two first sliders. The discharge plate is located at the lower right corner of the wheel and is used to receive the stainless steel pipe falling from the wheel.

[0018] Preferably, a second groove is provided on the back of the discharge plate, and a second slider is slidably connected inside the second groove. A movable rod is fixedly connected to the rear end of the second horizontal shaft, and the bottom end of the movable rod is fixedly connected to the back of the second slider. The discharge plate is driven to swing up and down through the movable rod and the second slider.

[0019] Preferably, a fixing block is fixedly connected to one side of each of the two vertical rods, and a hammer is fixedly connected to the top of the fixing block. The top of the hammer contacts the bottom outer wall of the discharge plate, and the bottom of the discharge plate is struck by the hammer.

[0020] 1. This invention, by setting up a feeding mechanism, uses a motor to drive the first horizontal shaft to rotate, causing the slot on the wheel to rotate and receive the stainless steel pipe, thus completing the continuous feeding of the stainless steel pipe and improving the processing efficiency of the stainless steel pipe. In addition, the feeding inclined plate vibrates up and down under the action of the cam, telescopic rod and spring, which further improves the continuity of the stainless steel pipe feeding and avoids the stainless steel pipe from getting stuck in the feeding inclined plate, thereby further improving the overall feeding efficiency.

[0021] 2. This invention utilizes a roller pressing mechanism. A disc rotates under the precise meshing of its drive teeth and gears, and the pressure rollers roll over the surface of the stainless steel tube, effectively releasing residual stress within it. When the disc rotates and engages the drive teeth and gears, the pressure rollers rotate in the forward direction to roll over the stainless steel tube. When the drive teeth and gears disengage, the torsion springs quickly rebound, causing the pressure rollers to rotate in the reverse direction. This forward and reverse rotation design results in a more uniform stress distribution within the stainless steel tube, optimizing its internal structure. Through this roller pressing process, the quality of the stainless steel tube is significantly improved, effectively reducing defects such as deformation and cracking caused by stress during subsequent use, thus enhancing product reliability and service life.

[0022] 3. This invention employs a vibration mechanism with a discharge plate that receives steel pipes falling from a rotating wheel. Driven by a second horizontal shaft and a movable rod, the discharge plate oscillates up and down. This oscillation has a dual effect: firstly, it shakes off impurities from the steel pipe surface, such as dust and debris accumulated during processing and transportation, effectively removing them and ensuring surface cleanliness. Secondly, the vibration further eliminates residual stress within the steel pipe. Simultaneously, the contact between the oscillating discharge plate and the striking hammer generates vibrations of different frequencies, further enhancing the removal of impurities and stress relief. The coordinated vibrations of different frequencies act on the steel pipe from different angles and intensities, resulting in more thorough stress elimination and ensuring the processed steel pipe meets quality standards and the demands of various high-precision applications.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-8 One embodiment of the present invention is: a stainless steel cutting device, including a base 1, and further comprising:

[0034] Cutting component 2, located above base 1, is used to cut stainless steel pipes;

[0035] Collection box 7, located above base 1, is used to collect the stainless steel pipes after cutting.

[0036] A first bracket 21 is fixedly connected to the top of the base 1. A motor slide rail 22 is fixedly connected to the first bracket 21. Two linear motors 23 are installed on the motor slide rail 22. A cutting machine 24 is installed at the bottom of the linear motors 23. The stainless steel pipe is cut by the cutting machine 24.

[0037] A feeding mechanism 4 is provided below the cutting machine 24. The feeding mechanism 4 includes a motor 41, a second bracket 42, a first horizontal shaft 43, a wheel 44, and a slot 45.

[0038] The motor 41 is fixedly connected to the back of the first bracket 21, and the second bracket 42 is fixedly connected to the top of the base 1. The rear end of the first horizontal shaft 43 passes through the first bracket 21 through a bearing and is fixedly connected to the front output end of the motor 41. The front end of the first horizontal shaft 43 passes through the second bracket 42 through a bearing. A wheel 44 is fixedly connected to the middle of the first horizontal shaft 43. Several slots 45 are provided on the wheel 44. The several slots 45 are rotatably set around the central axis of the first horizontal shaft 43. The stainless steel tube is limited by the slots 45.

[0039] A telescopic rod 46 is fixedly connected to the top of the base 1. A feeding inclined plate 3 is fixedly connected to the top of the telescopic rod 46. A spring 47 is sleeved on the outside of the telescopic rod 46. The top of the spring 47 is fixedly connected to the feeding inclined plate 3, and the bottom of the spring 47 is fixedly connected to the base 1. A cam 48 is fixedly connected to the middle of the first horizontal shaft 43. The cam 48 is located in front of the second bracket 42. A movable plate 49 is fixedly connected to the bottom of the feeding inclined plate 3 through a connecting rod. The top of the movable plate 49 contacts the cam 48. The movable plate 49 is pressed down by rotating the cam 48.

[0040] Working principle: First, multiple stainless steel pipes to be cut are placed on the feed ramp 3. Under the action of gravity, the stainless steel pipes will roll down to the lower right along the slope of the feed ramp 3 and adhere to the left side of the wheel 44. At this time, the motor 41 is turned on to drive the first horizontal shaft 43 to rotate. The rotation of the first horizontal shaft 43 drives the wheel 44 and the slot 45 to rotate. When the slot 45 rotates to the right side of the feed ramp 3, the first stainless steel pipe on the right side of the feed ramp 3 will enter the slot 45 under the action of gravity of the other stainless steel pipes. With the continuous rotation of the wheel 44 and the slot 45, it moves to the bottom of the two cutting machines 24, and the two cutting machines 24 cut the edges of the stainless steel pipe. With the continuous rotation of the wheel 44, the second stainless steel pipe... It will also get stuck in the second slot 45, and so on, to achieve continuous feeding and cutting of stainless steel pipes, improving the cutting efficiency of stainless steel pipes. When the first horizontal shaft 43 rotates, it drives the cam 48 to rotate. During the rotation of the cam 48, it continuously presses down the movable plate 49. The movable plate 49 moves downward and drives the feeding inclined plate 3 to move downward through the connecting rod. During the downward movement of the feeding inclined plate 3, it compresses the telescopic rod 46 and the spring 47. Then the spring 47 rebounds and drives the feeding inclined plate 3 to move upward. This is repeated, and the feeding inclined plate 3 moves up and down and generates vibration. The continuous vibration of the feeding inclined plate 3 makes the movement of stainless steel pipes smoother and less likely to get stuck in the feeding inclined plate 3, further improving the continuity of stainless steel pipe feeding.

[0041] Please see Figure 1-8Based on the above embodiments, in another embodiment of the present invention, a roller pressing mechanism 5 is provided on the right side of the wheel 44. The roller pressing mechanism 5 includes two vertical rods 53, which are fixedly connected to the top of the base 1. A second horizontal shaft 54 ​​is rotatably passed between the two vertical rods 53 through a bearing. A pressure roller 55 is fixedly connected to the middle of the second horizontal shaft 54. The pressure roller 55 is located at the upper right corner of the wheel 44. The pressure roller 55 is used to roll the surface of the stainless steel tube to release the residual stress inside.

[0042] A gear 56 is fixedly connected to the front end of the second horizontal shaft 54, and a disk 51 is fixedly connected to the front end of the first horizontal shaft 43. Multiple sets of transmission teeth 52 are arranged in an array on the outer side of the disk 51, and the transmission teeth 52 mesh with the gear 56.

[0043] A torsion spring 57 is sleeved on the outside of the second horizontal shaft 54. The rear end of the torsion spring 57 is fixedly connected to the vertical rod 53, and the front end of the torsion spring 57 is fixedly connected to the back of the pressure roller 55. The pressure roller 55 is reversed by the torsion spring 57.

[0044] Working principle: The rotation of the first horizontal shaft 43 drives the rotation of the disc 51, which in turn drives the rotation of the transmission gear 52. When the transmission gear 52 meshes with the gear 56, it drives the gear 56 to rotate. The rotation of the gear 56 drives the second horizontal shaft 54, the pressure roller 55, and the torsion spring 57 to rotate. During the rotation of the pressure roller 55, it rolls the stainless steel tube that rotates with the disc 44, thereby releasing the residual stress inside. As the disc 51 continues to rotate, the transmission gear 52 disengages from the gear 56. At this time, the torsion spring 57 rebounds and drives the pressure roller 55 to rotate in the opposite direction. This process is repeated. By continuously rolling the stainless steel tube with the pressure roller 55 in both forward and reverse directions, the stress distribution inside can be made more uniform.

[0045] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, a vibration mechanism 6 is provided below the pressure roller 55. The vibration mechanism 6 includes two first sliding grooves 61, which are respectively opened through two vertical rods 53. A first slider 62 is slidably connected inside the first sliding groove 61. A discharge plate 63 is fixedly connected between the two first sliders 62. The discharge plate 63 is located at the lower right corner of the wheel 44. The discharge plate 63 is used to receive the stainless steel pipe falling from the wheel 44.

[0046] The back of the discharge plate 63 is provided with a second slide groove 64, and a second slider 65 is slidably connected inside the second slide groove 64. A movable rod 66 is fixedly connected to the rear end of the second horizontal shaft 54. The bottom end of the movable rod 66 is fixedly connected to the back of the second slider 65. The discharge plate 63 is driven to swing up and down through the movable rod 66 and the second slider 65.

[0047] A fixing block 67 is fixedly connected to one side of the two vertical rods 53. A hammer 68 is fixedly connected to the top of the fixing block 67. The top of the hammer 68 contacts the bottom outer wall of the discharge plate 63, and the bottom of the discharge plate 63 is struck by the hammer 68.

[0048] Working principle: When the stainless steel tube rotates to the lower right corner of the wheel 44 along the slot 45, it rolls onto the discharge plate 63 under the action of gravity. At the same time, the second horizontal shaft 54 ​​rotates repeatedly, driving the movable rod 66 to swing repeatedly. The swinging of the movable rod 66 drives the discharge plate 63 to swing up and down through the second slider 65, generating vibration. The vibration eliminates the residual stress in the stainless steel tube on the discharge plate 63. During the up and down swinging process, the discharge plate 63 will come into contact with the hammer 68. The hammer 68 strikes the discharge plate 63 to generate vibrations of different frequencies. The two different frequencies of vibration improve the effect of eliminating the residual stress in the stainless steel tube.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
