Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and specifically to an adjustable cutting device for processing stainless steel products. Background Technology

[0002] Stainless steel products refer to various items made of stainless steel. They have a variety of excellent properties. Stainless steel is an alloy steel containing alloying elements such as chromium and nickel. The addition of chromium causes a dense chromium oxide film to form on its surface. This film can prevent the internal metal from being further oxidized, giving stainless steel good corrosion resistance. It is not easy for it to rust or corrode in humid, acidic, or alkaline environments. Stainless steel products are widely used in many fields such as building decoration, kitchenware and tableware, medical devices, industrial equipment, automobile manufacturing, and aerospace, providing people's lives and production with high-quality, durable, and beautiful products.

[0003] Stainless steel pipe cutting is an operation that separates and processes tubular materials made of stainless steel. Common methods include mechanical cutting, such as using a saw, which offers high cutting precision and a relatively smooth cut. It is suitable for stainless steel pipes of various diameters. However, cutting thicker steel pipes generates a lot of heat, which may cause changes in the metal structure at the cut, creating a heat-affected zone. At the same time, the slag and chips produced during cutting may re-adhere to the surface of the steel pipe, affecting the processing quality. Therefore, we have proposed an adjustable cutting device for processing stainless steel products. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an adjustable cutting device for processing stainless steel products, comprising:

[0005] A base plate, wherein an upper tube is provided on the top of the base plate, and a lower tube is provided at the interval between the upper tube and the base plate;

[0006] A cutting mechanism is provided at the interval between the upper tube and the lower tube, and the side of the upper tube and the lower tube that are close to each other is fixedly connected to the cutting mechanism. The cutting mechanism is fixedly connected to the top of the base plate.

[0007] The cutting mechanism includes:

[0008] A protective cover is provided at the interval between the upper tube and the lower tube, and the inner side of the protective cover is fixedly connected to the outer side of the upper tube and the lower tube.

[0009] A lifting assembly, wherein the inner side of the lifting assembly is fixedly connected to the outer side of the upper tube, and the lifting assembly is fixedly connected to the top of the base plate;

[0010] The fixing component is fixedly connected to the inner side of the upper tube;

[0011] The saw blade is disposed at the interval between the upper and lower tubes. A drive assembly is fixedly connected to the side of the saw blade away from the center of the protective cover, and the drive assembly is located inside the protective cover.

[0012] An air jet assembly is fixedly connected to the side of the lower tube away from the upper tube;

[0013] The lifting assembly is activated, causing the upper pipe, protective cover, and lower pipe to rise. The top of the upper pipe receives the stainless steel pipe, which slides into its interior. The fixing assembly then activates, securing the pipe. The lifting assembly descends and resets, followed by the activation of the drive assembly. This drive assembly rotates the saw blade to cut the pipe, simultaneously feeding the blade through it and severing it. While cutting, the air jet assembly activates, releasing protective gas. The fumes are expelled from the top of the upper pipe with the airflow, protecting the pipe from oxidation and thermal deformation. The airflow passes sequentially through the lower and upper pipes, creating an upward airflow that flows in the opposite direction to the falling chips and slag, slowing their descent and preventing splashing. This also cools the chips and slag, preventing them from re-adhering to the inside of the pipe. External air enters the gap between the upper and lower pipes through the protective cover, rising along with the protective gas column. To prevent fumes, chips, and slag from entering the protective cover and affecting the operation of the drive components, and to ensure that the protective gas protects the steel pipe welding position, the external air rises along the outside of the protective gas column, preventing external air from contacting the welding position. Then, the lifting component is restarted, which again lifts the upper pipe, protective cover, and lower pipe. The fixing component is then removed, and the cut steel pipe is unloaded from the bottom of the lower pipe. The top of the upper pipe receives another stainless steel pipe and is fixed by the fixing component for further processing.

[0014] Furthermore, the drive assembly includes a machine head, the inner side of which is rotatably connected to the inner side of the saw blade via a rotating rod, and the machine head drives the saw blade to rotate via the rotating rod. A drive telescopic rod is fixedly connected to the side of the machine head away from the saw blade, and the drive telescopic rod is located on the side of the saw blade away from the center of the protective cover. A fixed frame is fixedly connected to the side of the drive telescopic rod away from the machine head. When the machine head is started, it drives the saw blade to rotate and cut the steel pipe. When the drive telescopic rod is started, its output end drives the machine head to move, which in turn drives the saw blade to move, and the saw blade feeds towards the center of the steel pipe.

[0015] Furthermore, a slide is fixedly connected to the side of the fixed frame near the protective cover, and sliders are symmetrically arranged on the side of the slide away from the fixed frame. The sides of the two sliders that are close to each other are fixedly connected to the surface of the slide. Slide grooves are opened on the sides of the upper and lower tubes that are close to each other. The sides of the two sliders that are far from each other are fixedly connected to the inner sides of the two slide grooves respectively. The sliders are designed in a dovetail shape, which drives the fixed frame to rotate, drives the telescopic rod to rotate, and finally drives the saw blade to revolve around the steel pipe to achieve circumferential cutting. At the same time, the fixed frame drives the slide to rotate, drives the slider to rotate, and the slider rotates inside the slide groove, thereby limiting the circular rotation trajectory and ensuring the stability of circumferential cutting. Moreover, the dovetail-shaped slide groove is more stable during rotation and obtains a better limiting effect.

[0016] Furthermore, symmetrical slide rails are provided at the interval between the upper and lower tubes. The sides of the two slide rails that are close to each other are fixedly connected to the surface of the carriage, and the sides of the two slide rails that are far apart from each other are provided with limit rings. The inner sides of the two limit rings are fixedly connected to the outer sides of the upper and lower tubes, respectively, and the sides of the two limit rings that are close to each other are slidably connected to the inner sides of the two slide rails. The inner sides of the slide rails are designed as dovetail grooves. When the carriage rotates, it drives the slide rails to rotate, and the slide rails rotate along the limit rings, thereby further limiting the movement and achieving double limiting to obtain a better limiting effect.

[0017] Furthermore, each of the slides has a feed groove on the side away from the slider. The inner sides of the two feed grooves are slidably connected to a sliding plate. The sides of the two sliding plates that are close to each other are fixedly connected to the surface of the head. When the head feeds, it drives the sliding plate to slide inside the feed groove, thereby limiting the feed of the saw blade and preventing the saw blade from shaking when penetrating the steel pipe. This ensures the smoothness of the steel pipe cross-section and avoids the formation of steps and burrs on the cross-section.

[0018] Furthermore, a clamping sleeve is fixedly connected to the inner side of the slide, and the inner side of the clamping sleeve is slidably connected to the surface of the drive telescopic rod. The side of the clamping sleeve that is close to the saw blade is slidably connected to the surface of the slide plate. After the cutting is completed, the slide plate returns to the inside of the clamping sleeve, and the clamping sleeve clamps the slide plate, thereby limiting the position when the cutting stops, preventing the saw blade from shaking again when loading and unloading steel pipes, and thus preventing the saw blade from becoming loose.

[0019] Furthermore, a drive rod is fixedly connected to the outer side of the chuck, and the drive rod is located on the side of the slide close to the fixed frame. The side of the drive rod away from the base plate passes through the fixed frame, and the inner side of the fixed frame is slidably connected to the surface of the drive rod. A ring tooth is fixedly connected to the end of the drive rod away from the chuck, and the ring tooth is sleeved on the outside of the upper tube. A gear is meshed with the inner side of the ring tooth. A rotating shaft is fixedly connected to the side of the gear away from the ring tooth, and a motor is fixedly connected to the side of the rotating shaft away from the gear. The surface of the motor is fixedly connected to the outer side of the upper tube. When the motor is started, the output end of the motor drives the rotating shaft to rotate, which drives the gear to rotate, which drives the ring tooth to rotate, which drives the drive rod to rotate, and finally drives the saw blade to revolve around the steel pipe to achieve circumferential cutting.

[0020] Furthermore, the lifting assembly includes a lifting frame, the inner side of which is fixedly connected to the outer side of the upper tube. A lifting rod is fixedly connected to the side of the lifting frame near the base plate, and the side of the lifting rod away from the lifting frame is fixedly connected to the top of the base plate. Several lifting rods are evenly distributed around the circumference of the lifting frame. When the lifting rod is activated, the output end of the lifting rod drives the lifting frame to rise and fall, thereby driving the upper tube, the protective cover, and the lower tube to rise and fall. When rising, the upper tube aligns with the steel pipe loading position, and the lower tube aligns with the unloading position. After descending and resetting, it reaches the steel pipe processing position.

[0021] Furthermore, the fixing assembly includes a fixed telescopic rod, which is fixedly connected to the inner side of the upper pipe. Several fixed telescopic rods are evenly distributed along the circumference of the upper pipe. A fixing plate is fixedly connected to one end of the fixed telescopic rod near the center of the upper pipe. The side of the fixing plate away from the fixed telescopic rod is arc-shaped. A limit frame is slidably connected to the outer side of the fixed telescopic rod. The side of the limit frame away from the fixing plate is fixedly connected to the inner side of the upper pipe. When the fixed telescopic rod is activated, it drives the fixing plate to move. The several fixing plates clamp the steel pipe. The limit frame limits the output end of the fixed telescopic rod to prevent it from tilting.

[0022] Furthermore, an air cylinder is installed on the side of the lower pipe away from the upper pipe, and the air cylinder is located inside the lower pipe. A filter plate is fixedly connected to the side of the air cylinder away from the bottom plate. The filter plate is conical, and the side of the filter plate away from the air cylinder is fixedly connected to the inner side of the lower pipe. A bend is provided at the interval between the air cylinder and the lower pipe. The end of the bend away from the filter plate passes through the lower pipe, and the outer side of the bend is fixedly connected to the inner side of the lower pipe. The bends are evenly distributed around the circumference of the air cylinder. An annular plate is also provided at the interval between the air cylinder and the lower pipe. The inner and outer sides of the annular plate are fixedly connected to the sides of the air cylinder and the lower pipe that are close to each other, respectively. The end of the bend away from the bottom plate passes through the annular plate, and the outer side of the bend is fixedly connected to the inner side of the annular plate. An air hood is fixedly connected to the outer side of the lower pipe. Several of the aforementioned bends are located outside the lower pipe, with one end set inside the gas hood. An air inlet pipe is fixedly connected to the side of the gas hood away from the bottom plate. A pump body is fixedly connected to the side of the air inlet pipe away from the gas hood. The pump body is fixedly connected to the outer side of the lower pipe. A connecting pipe is fixedly connected to the end of the pump body away from the air inlet pipe. The connecting pipe is connected to the protective gas. When the pump body is started, the protective gas passes through the connecting pipe, pump body, air inlet pipe, gas hood, and bends in sequence, and finally enters the lower pipe after passing through the filter plate. It reaches the cutting position and finally leaves the upper pipe with the flue gas. The conical filter plate can guide the cooled and solidified chips and slag into the gas cylinder, and finally complete the feeding of chips and slag. The several bends distributed around the circumference can form a uniform gas column to achieve protection and cooling at various positions of the steel pipe.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. This invention, through the setting of a cutting mechanism, uses a jet assembly to spray protective gas. The fumes are discharged from the top of the upper pipe with the airflow, protecting the steel pipe during cutting and preventing oxidation and thermal deformation. The airflow passes through the lower and upper pipes in sequence, generating an upward airflow that is opposite to the falling direction of the chips and slag, which slows down their falling speed and prevents splashing. At the same time, it cools the chips and slag, preventing them from re-adhering to the inside of the steel pipe. External air enters the gap between the upper and lower pipes through the protective cover. The external air adheres to the outside of the protective gas column and rises with it, preventing fumes, chips, and slag from entering the inside of the protective cover and affecting the operation of the drive assembly. Furthermore, the external air rising along the outside of the protective gas column prevents external air from contacting the welding position, ensuring the protective effect of the protective gas on the welding position of the steel pipe.

[0025] 2. By setting up a driving component, the slider rotates inside the slide groove, thereby limiting the rotation trajectory of the ring and ensuring the stability of the ring cutting. The dovetail-shaped slide groove is more stable during rotation, achieving a better limiting effect. The slide rail rotates along the limiting ring, thereby further limiting the position and achieving double limiting for a better limiting effect.

[0026] 3. This invention sets up a feed groove, in which the slide plate slides, thereby limiting the feed of the saw blade and preventing it from shaking when penetrating the steel pipe. This ensures a smooth cross-section of the steel pipe and avoids the formation of steps and burrs. After cutting, the slide plate returns to the inside of the clamping cylinder, which clamps the slide plate and limits its movement when cutting stops. This prevents the saw blade from shaking again when loading or unloading steel pipes and avoids the saw blade from becoming loose.

[0027] 4. By setting up an air jet assembly, the present invention can carry the flue gas away from the upper pipe. The conical filter plate can guide the cooled and solidified chips and slag into the air cylinder, and finally complete the feeding of chips and slag. Furthermore, the several circumferentially distributed curved pipes can form a uniform air column to achieve protection and cooling of various parts of the steel pipe. Attached Figure Description

[0047] The lifting assembly 42 is activated, causing the upper pipe 2, protective cover 41, and lower pipe 3 to rise. The top of the upper pipe 2 receives the stainless steel pipe, which slides into the interior. The fixing assembly 43 is activated to secure the pipe. The lifting assembly 42 then descends and resets. Subsequently, the drive assembly 45 is activated, driving the saw blade 44 to rotate and cut the pipe. Simultaneously, the drive assembly 45 drives the saw blade 44 to feed, penetrating the pipe. The drive assembly 45 also drives the saw blade 44 to revolve around the pipe, cutting it off. Air jets are emitted during the cutting process. When component 46 is activated, the jet assembly 46 ejects protective gas. The fumes are discharged from the top of the upper pipe 2 with the airflow, protecting the steel pipe during cutting and preventing oxidation and thermal deformation. The airflow passes sequentially through the lower pipe 3 and the upper pipe 2, generating an upward airflow that is opposite to the falling direction of the chips and slag. This slows down their falling speed, preventing splashing, and also cools the chips and slag, preventing them from re-adhering to the inside of the steel pipe. External air enters the gap between the upper pipe 2 and the lower pipe 3 through the protective cover 41, and rises along with the outer side of the protective gas column. To prevent fumes, chips, and slag from entering the protective cover 41 and affecting the operation of the drive assembly 45, and to prevent external air from rising along the outside of the protective gas column, ensuring the protective gas's effectiveness in protecting the steel pipe welding position, the lifting assembly 42 is then restarted. The lifting assembly 42 again lifts the upper pipe 2, the protective cover 41, and the lower pipe 3. The fixing assembly 43 is then removed, and the cut steel pipe is unloaded from the bottom of the lower pipe 3. The top of the upper pipe 2 receives another stainless steel pipe and is fixed by the fixing assembly 43 for further processing.

The head 451 drives the saw blade 44 to rotate via the rotating rod. A drive telescopic rod 452 is fixedly connected to the side of the head 451 away from the saw blade 44. The drive telescopic rod 452 is located on the side of the saw blade 44 away from the center of the guard 41. A fixing frame 453 is fixedly connected to the side of the drive telescopic rod 452 away from the head 451. When the head 451 is started, it drives the saw blade 44 to rotate and cut the steel pipe. When the drive telescopic rod 452 is started, its output end drives the head 451 to move, which in turn drives the saw blade 44 to move, and the saw blade 44 feeds towards the center of the steel pipe.

[0049] A slide 454 is fixedly connected to the side of the fixed frame 453 near the protective cover 41. Sliders 455 are symmetrically arranged on the side of the slide 454 away from the fixed frame 453. The sides of the two slides 455 that are close to each other are fixedly connected to the surface of the slide 454. Slide grooves 456 are opened on the sides of the upper tube 2 and the lower tube 3 that are close to each other. The sides of the two slides 455 that are far from each other are fixedly connected to the inner surfaces of the two slide grooves 456 respectively. The slides 455 are designed in a dovetail shape. The fixed frame 453 is driven to rotate, which drives the telescopic rod 452 to rotate, and finally drives the saw blade 44 to revolve around the steel pipe to achieve circumferential cutting. At the same time, the fixed frame 453 drives the slide 454 to rotate, which drives the slides 455 to rotate. The slides 455 rotate inside the slide grooves 456, thereby limiting the circular rotation trajectory and ensuring the stability of the circumferential cutting. The dovetail-shaped slide grooves 456 are more stable during rotation and obtain a better limiting effect.

The inner sides of the slide rails 457 are set in a dovetail groove shape. When the carriage 454 rotates, it drives the slide rails 457 to rotate. The slide rails 457 rotate along the limiting rings 458, thereby further limiting and achieving double limiting to obtain a better limiting effect.

[0051] The slide 454 has a feed groove 459 on the side away from the slider 455. The inner sides of the two feed grooves 459 are slidably connected to the slide plate 4510. The sides of the two slide plates 4510 that are close to each other are fixedly connected to the surface of the head 451. When the head 451 feeds, it drives the slide plate 4510 to slide inside the feed groove 459, thereby limiting the feed of the saw blade 44 and preventing the saw blade 44 from shaking when penetrating the steel pipe, thus ensuring the smoothness of the steel pipe cross-section and avoiding the formation of steps and burrs on the cross-section.

After cutting, the slide plate 4510 returns to the inside of the clamping sleeve 4511. The clamping sleeve 4511 clamps the slide plate 4510, thereby limiting the position when cutting stops, preventing the saw blade 44 from shaking again when loading and unloading steel pipes, thus preventing the saw blade 44 from becoming loose.

The side of the lifting rod 422 away from the lifting frame 421 is fixedly connected to the top of the base plate 1. Several lifting rods 422 are evenly distributed around the circumference of the lifting frame 421. When the lifting rod 422 is activated, the output end of the lifting rod 422 drives the lifting frame 421 to rise and fall, which in turn drives the upper tube 2, the protective cover 41, and the lower tube 3 to rise and fall. When rising, the upper tube 2 aligns with the steel pipe loading position, and the lower tube 3 aligns with the unloading position. After descending and resetting, it reaches the steel pipe processing position.

When the pump body 467 is started, the protective gas passes through the connecting pipe in sequence. 468, pump body 467, air inlet pipe 466, air hood 465, bend pipe 463, finally enter the lower pipe 3 after passing through the filter plate 462, reach the cutting position, and finally leave from the upper pipe 2 with the flue gas. The conical filter plate 462 can guide the cooled and solidified chips and slag into the air cylinder 461, and finally complete the feeding of chips and slag. The several bend pipes 463 distributed around the circumference can form a uniform air column to achieve protection and cooling of various parts of the steel pipe.

[0057] In use, the lifting rod 422 is activated, and its output end drives the lifting frame 421 to rise and fall, which in turn drives the upper pipe 2, the protective cover 41, and the lower pipe 3 to rise and fall. During loading, the lifting rod 422 extends, and the top of the upper pipe 2 receives the stainless steel pipe, which slides into the upper pipe 2. The fixed telescopic rod 431 is then activated, causing the fixed plates 432 to move. Several fixed plates 432 clamp the steel pipe. Afterward, the lifting rod 422 resets, and the machine head 451 is activated, driving the saw blade 44 to rotate and cut the steel pipe. Cutting begins. The drive telescopic rod 452 is activated, its output driving the machine head 451 to move, which in turn moves the saw blade 44. The saw blade 44 feeds towards the center of the steel pipe. The motor 4516 is then activated, its output driving the rotating shaft 4515 to rotate, which in turn drives the gear 4514 to rotate, which in turn drives the ring gear 4513 to rotate, causing the drive rod 4512 to rotate. The drive rod 4512 then drives the chuck 4511 to rotate, which in turn drives the slide 454 to rotate, which in turn drives the slide rail 457 to rotate. The slide rail 457 moves along the limiting ring 458. The fixed frame 453 rotates, driving the drive telescopic rod 452 to rotate, ultimately causing the saw blade 44 to revolve around the steel pipe, achieving circumferential cutting. Simultaneously, the fixed frame 453 drives the slide 454 to rotate, which in turn drives the slider 455 to rotate. The slider 455 rotates inside the slide groove 456. The rotation of the slide 454 drives the slide rail 457 to rotate, which rotates along the limiting ring 458. The connecting pipe 468 connects to the protective gas, and the pump body 467 is started. The protective gas passes sequentially through the connecting pipe 468, the pump body 467, the air inlet pipe 466, the air cover 465, and the bend. 463, after passing through the filter plate 462, enters the lower pipe 3, reaches the cutting position, and finally leaves the upper pipe 2 carrying the flue gas. The conical filter plate 462 can guide the cooled and solidified chips, slag, etc. into the air cylinder 461. Then, the lifting component 42 is activated again, which drives the upper pipe 2, the protective cover 41, and the lower pipe 3 to rise again. The fixing component 43 is released, and the cut steel pipe is discharged from the bottom of the lower pipe 3. The top of the upper pipe 2 receives another stainless steel pipe and is fixed by the fixing component 43 for further processing.
