[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Example 1: See Figure 1-3 As shown, a supporting mechanism for a stainless steel pipe includes a base 1, a supporting frame 2 and a driving supporting cylinder 3;

[0032] The bottom of the support frame 2 is rotatably mounted on the base 1, and two support rollers 4 are rotatably mounted on the front end of the support frame 2. The two support rollers 4 are parallel and spaced apart from each other, and a support spacing 5 is formed between the two support rollers 4.

[0033] The driving support cylinder 3 is arranged at the rear side of the supporting roller 4, the bottom of the driving support cylinder 3 is rotatably connected to the base 1, and the output shaft at the top of the driving support cylinder 3 is rotatably connected to the rear end of the supporting frame 2;

[0034] A loading rack 6 is also provided on the support frame 2 above the driving support cylinder 3. The loading rack 6 is installed on the support frame 6 via multiple mounting rods 7. The loading rack 6 is arranged downwardly from the back to the front. The front end of the loading rack 6 is arranged above and behind the rear support roller 4, and the front end of the loading rack 6 is arranged opposite to the support spacing 5.

[0035] In this embodiment, the support gap is used to support the rolling placement of products (stainless steel pipes or other pipes). A processing mechanism can be located above the support gap to automatically or manually process the products, or at the ends of the support gap to automatically or manually process the products. When the output shaft of the drive support cylinder is retracted, the tops of the two support rollers form a plane parallel to the top surface of the base. When the output shaft of the drive support cylinder is extended, the tops of the two support rollers form a plane that tilts downward from the back to the front. The drive support cylinder can be a pneumatic cylinder or an oil cylinder, with the hydraulic pressure of the oil cylinder being greater than the force of the pneumatic cylinder, and the choice is based on actual conditions. When processing the product, the output shaft of the drive support cylinder retracts, and a product falls onto the loading rack. Due to the tilt of the loading rack, the product rolls forward and falls into the support gap. The processing mechanism can then be used to perform the corresponding operation on the product. During operation, the product is supported by the support rollers for rolling support. At the same time, the front end of the support rack is subjected to downward pressure, which is then pulled by the drive support cylinder to stabilize the support rack in this position. After the operation or processing is complete, the output shaft of the drive support cylinder extends, pushing the front end of the support frame downward. This causes the products within the support gap to roll forward and fall out of the gap, achieving automatic unloading. After unloading is complete, the output shaft of the drive support cylinder retracts, driving the support frame back to its original position, ready for the next group of products to be processed. This structure is simpler, can achieve both loading and unloading functions, and is more cost-effective.

[0036] See also Figure 1 、 2 As shown, the base 1 is also provided with at least one supporting component, and the supporting component includes a supporting cylinder 8 and a supporting plate 9. The bottom of the supporting cylinder 8 is fixedly mounted on the base 1, and the supporting plate 9 is arranged on the output shaft of the supporting cylinder 8; the supporting plate 9 is arranged below the supporting frame 2, and when the output shaft of the supporting cylinder is extended, the supporting plate 9 is in contact with the bottom of the supporting frame 2.

[0037] There are two groups of support components, which are respectively arranged on both sides of the front end of the driving support cylinder, and are respectively arranged below both sides of the support distance.

[0038] In this embodiment, when the support roller supports and processes the product, the front end of the support frame is subjected to downward pressure, which is transmitted to the driving support cylinder. That is, the support frame applies a pulling force to the driving support cylinder. If the driving support cylinder is subjected to this pulling force for a long time and the pulling force is not parallel to the axis of the driving support cylinder, it is easy to be damaged (mainly due to deformation of the output shaft of the driving support cylinder, which leads to uneven movement between the output shaft of the driving support cylinder and the cylinder body of the driving support cylinder, air leakage or fluid leakage, etc.). Therefore, in order to extend the service life of the driving support cylinder and ensure the stability of the support frame in supporting the product processing, two groups of support cylinders are further provided. Each support cylinder is arranged below the support frame on both sides of the support gap. After the output shaft of the driving support cylinder retracts, the output shaft of the support cylinder extends, driving the support plate to move against the support frame. In this way, the product is within the support gap. During processing, the support frame can also be supported by the support plate and the support cylinder, thereby reducing the pulling force of the support frame on the driving support cylinder, thereby preventing damage to the driving support cylinder and extending its service life (the driving support cylinder is larger in size and the cost is higher than that of ordinary support cylinders).

[0039] See also Figure 1 、 2 As shown, the support frame 2 includes two sets of side members 10 spaced apart from each other on the left and right sides and two connecting shafts 11 spaced apart from each other on the top and bottom sides. The side members 10 include a first rod 12, a second rod 13 and an arc-shaped rod 14. The first rod 12 is arranged perpendicular to the second rod 13. The rear end of the first rod 12 is connected to the top of the second rod 13 through the arc-shaped rod 14.

[0040] The upper connecting shaft 11 is connected to the arc-shaped rods 14 of the two sets of side parts 10, and the lower connecting shaft 11 is connected to the bottom of the second rod 13 of the two sets of side parts 10, and the lower connecting shaft 11 is rotatably connected to the base 1;

[0041] Both ends of the two support rollers 4 are rotatably connected to the first rods 12 of the two groups of side components 10 respectively, and the connecting shaft 11 is arranged parallel to the support rollers 4.

[0042] In this embodiment, the side parts form an L-shaped structure, and two sets of side parts are connected by two connecting shafts to form a support frame. The support frame has a simple structure, low cost and good firmness.

[0043] See also Figure 1 、 2 As shown, each of the first rods is provided with a mounting rod, and the upper connecting shaft is also provided with two mounting rods.

[0044] The front and left sides of the loading rack are supported by two sets of side parts, while the middle and rear sides are supported by connecting shafts.

[0045] See also Figure 1 、 2 As shown, the middle part of the upper connecting shaft 11 is provided with an inclined plate 15 inclined toward the rear and upward, and the output shaft of the driving support cylinder 3 is rotatably connected to the rear end of the inclined plate 15. The setting of the inclined plate is used to connect the driving support cylinder with the support frame.

[0046] See also Figure 1 、 2 As shown, each side member 10 further includes a reinforcing rod 16, the ends of which are connected to the middle portion of the first rod and the middle portion of the second rod, respectively. To increase the strength of the first rod and prevent deformation of the first rod, the reinforcing rod is provided, so that the first rod, the second rod, and the reinforcing rod form a triangular structure, which has better strength and stability, a simple structure, and low cost.

[0047] See also Figure 3 As shown, the utility model also provides a cutting device for stainless steel pipe fittings, including the above-mentioned support mechanism for stainless steel pipe fittings, and also includes a lifting and cutting mechanism, the lifting and cutting mechanism includes two groups of hydraulic cylinders 20, a mounting portion 21 and at least one cutting saw 22, the bottoms of the two groups of hydraulic cylinders 20 are respectively installed on the base 1 at both ends of the support spacing, the two ends of the mounting portion 21 are connected to the output shafts at the tops of the two groups of hydraulic cylinders 20, the cutting saw 22 is installed on the mounting portion, and the outer surface of the bottom of the cutting saw is arranged below the bottom surface of the mounting portion.

[0048] There are two groups of cutting saws, and the two groups of cutting saws are respectively arranged above the two sides of the support distance.

[0049] In this embodiment, the cutting saw is capable of high-speed rotation and includes a motor and a saw blade. The motor drives the saw blade to rotate at high speed, with the bottom of the saw blade positioned below the bottom surface of the mounting portion. When the output shaft of the driving support cylinder is retracted, the support gap is positioned below the mounting portion. During use, when a product enters the support gap, the output shaft of the hydraulic cylinder retracts, driving the mounting portion and, consequently, the cutting saw downward, the product is then cut by the high-speed rotating saw blade.

[0050] See also Figure 3 As shown, a pressure roller 23 is further provided. A concave cavity 24 is provided in the middle of the bottom surface of the mounting portion 21. The concave cavity 24 is provided between the two groups of cutting saws 22. The pressure roller 23 is rotatably installed in the concave cavity, and the bottom surface of the pressure roller 23 is provided below the bottom surface of the concave cavity 24.

[0051] A pressure roller drive motor 25 is provided on the top surface of the mounting portion 21. The pressure roller drive motor 25 is connected to one end of the pressure roller 23 via a belt 26. The bottom of the belt passes through the mounting portion and is connected to one end of the pressure roller to drive the pressure roller to rotate.

[0052] In this embodiment, the saw blade is a circular saw blade. In conventional methods, if the product cannot rotate, the radius of the saw blade needs to be greater than the diameter of the product in order to cut the product. In order to improve cutting efficiency, reduce the size of the saw blade, and reduce the space occupied by the saw blade below the mounting portion, a pressure roller is provided. The pressure roller drive motor drives the pressure roller to rotate. When the mounting portion moves downward, the saw blade first contacts the product and cuts off part of the product (the cutting distance is greater than the wall thickness of the product). Then, the mounting portion moves downward, and the pressure roller presses on the top outer surface of the product. The two ends of the pressure roller are connected to the bearing and the concave cavity for rotation. One end of the pressure roller passes through the bearing and leaks out of the bearing. It is connected to the pressure roller drive motor through a belt. In this way, the pressure roller drive motor drives the pressure roller to rotate, which will also drive the product to rotate. During the rotation of the product, the cutting saw can be used to perform circular cutting on the product, reducing the diameter of the saw blade. In this embodiment, the motor is installed on the top of the mounting part, and a through slot is provided on the mounting part to connect with the bottom surface of the mounting part. The bottom of the saw blade passes through the through slot and is below the bottom surface of the mounting part. The vertical distance between the bottom of the saw blade to the bottom surface of the mounting part to the bottom surface of the pressure roller is greater than the wall thickness of the product.

[0053] See also Figure 3 As shown, the base 1 is further provided with a blanking rack 27 , the top of the blanking rack 27 is tilted downward from the back to the front, and the blanking rack 27 is arranged on the front side of the supporting roller 4 .

[0054] The blanking rack serves as a guide for the material being dropped. After the output shaft of the drive support cylinder extends, the support spacing gradually tilts forward from a vertical position until the product rolls forward from the top of the front support rollers. It falls onto the blanking rack, acting as a guide, preventing the product from falling directly from a high point and causing damage to the base, while also reducing noise and increasing safety.
