Description

Technical Field

[0001] This application relates to the field of steel pipe processing technology, and in particular to a steel pipe switching device and its usage method. Background Technology

[0002] Steel pipes are commonly used in building structures, metal processing, and pipe manufacturing. Depending on their application and specific requirements, steel pipes come in different shapes, sizes, and thicknesses. Cutting is an indispensable and crucial step in the processing of steel pipes. Accurate processing of steel pipes to meet the required dimensions and shapes directly affects the quality and applicability of the final product.

[0003] Currently, some cutting devices rely on real-time measurement when adjusting the cutting size. This means that measurement and adjustment are required before each cut. Such real-time adjustment is not only time-consuming but also introduces certain measurement errors, increases downtime in production, and limits the continuity of cutting.

[0004] Therefore, we need a steel pipe switching device and its usage method to solve the problem that the cutting device cannot switch sizes in real time for continuous cutting. Summary of the Invention

[0005] The purpose of this application is to provide a steel pipe switching device and its usage method, which can solve the problem that the cutting device cannot switch sizes in real time for continuous cutting.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solution: a steel pipe switching device, comprising: a supporting device, which is arranged in parallel and is used for support; a cutting device, which is disposed on the supporting device and is used for cutting steel pipes; and a limiting device, comprising: an operating table, which is disposed below the cutting device and connected to the supporting device, with sliding grooves on both sides of the operating table, the sliding grooves being symmetrically arranged, and graduations being provided on the outer side of the sliding grooves; and a fixing block, which is disposed on the operating table, the fixing block being trapezoidal, and having a groove in the middle of the fixing block. The device consists of a groove for placing the steel pipe, a square limiting block located to the left of the fixed block with protrusions on both sides, one end of which is connected to the limiting block and the other end located in a groove on the operating table, used to block the steel pipe, and a collecting device located below the limiting block for collecting the pipe. The distance between the limiting block and the fixed block is adjusted by moving the protrusions on both sides of the limiting block within the groove on the operating table, thereby adjusting the length of the steel pipe to be cut. The steel pipe is then inserted into the groove of the fixed block, and after the front end of the steel pipe contacts the limiting block, the cutting device is activated to complete the cut.

[0007] In the above technical solution, this embodiment uses a sliding groove to adjust the position of the limiting block on the operating table, presets the length of the steel pipe to be cut, inserts the steel pipe into the groove of the fixing block, so that the top of the steel pipe contacts the limiting block, and then cuts the steel pipe by the cutting assembly. The cut steel pipe falls through the discharge chute of the operating table, and the operation is repeated to perform continuous cutting. Furthermore, the steel pipe can be tilted by rotating the fixing block to perform oblique cutting. The waste material after oblique cutting will fall through the waste chute next to the discharge chute for classified collection. This solves the problem that the cutting device cannot switch sizes in real time for continuous cutting, achieving the effect of continuous cutting with real-time size switching.

[0008] Furthermore, according to an embodiment of this application, the support device further includes:

[0009] The base plate is located at the lower end of the support device.

[0010] The support plate is set on the base plate. The support plate is an inverted L-shaped plate and is used to connect the cutting device and the operating table.

[0011] Furthermore, according to embodiments of this application, the cutting device further includes:

[0012] The hydraulic device is mounted on the support plate and connected to the inside of the support plate.

[0013] A connecting plate is mounted on the hydraulic device. One end of the connecting plate is connected to the hydraulic device, and the other end of the connecting plate is provided with a connection hole.

[0014] The cutting assembly is mounted on the connecting plate and is used to cut steel pipes.

[0015] Furthermore, according to an embodiment of this application, the cutting assembly is disposed at the other end of the connecting plate, with a motor disposed on its inner side and a cutting disc disposed on its outer side, which is connected through the connecting hole of the connecting plate.

[0016] Furthermore, according to an embodiment of this application, the cutting assembly drives the connecting plate to move via a hydraulic device, and simultaneously drives the cutting assembly to move up and down to cut the steel pipe fixed on the fixed block.

[0017] Furthermore, according to an embodiment of this application, a material discharge chute is also provided in the middle of the operating table.

[0018] Furthermore, according to an embodiment of this application, the feeding trough is square and connects to the operating table and the collecting device.

[0019] Furthermore, according to an embodiment of this application, the groove of the fixing block is circular or square, used for cutting steel pipes of different shapes.

[0020] Furthermore, according to an embodiment of this application, the collecting device is square and hollow.

[0021] To achieve the above objectives, this application also discloses a method for using a steel pipe switching device, comprising the following steps:

[0022] To install, place the device on a horizontal surface and use a hydraulic system to raise the cutting assembly to a preset height. Then, place the collecting device under the operating table.

[0023] Adjustments are made by rotating the fixed block to select the angle at which the steel pipe needs to be cut at an angle, and by adjusting the position of the limit block on the operating table to preset the length of the steel pipe to be cut.

[0024] Cutting involves placing the steel pipe inside a fixed block, using a hydraulic device to lower the cutting assembly to make a slanted cut on the steel pipe, then inserting the steel pipe deeper until the top of the steel pipe contacts the limiting block, and then cutting the steel pipe again using the cutting assembly. This process is repeated to continuously process the steel pipe.

[0025] The cut steel pipes will be collected and fed into the collection device through the feeding chute on the operating table under the action of gravity. After being buffered multiple times by the baffles inside the collection device, they will accumulate at the bottom of the collection bucket. Meanwhile, the waste material from the oblique cutting of the steel pipes will fall into the waste bucket through the waste chute next to the feeding chute.

[0026] Compared with existing technologies, this application has the following advantages: This application employs a steel pipe switching device and its usage method. The position of the limiting block on the operating table is adjusted via a sliding groove, and the length of the steel pipe to be cut is preset. Then, the steel pipe is inserted into the groove of the fixing block, so that the top of the steel pipe contacts the limiting block. The cutting assembly then cuts the steel pipe, and the cut steel pipe falls through the discharge chute on the operating table. This process is repeated for continuous cutting. Furthermore, the steel pipe can be tilted by rotating the fixing block, thus performing oblique cutting. The waste material from the oblique cut falls through a waste chute on the side of the discharge chute for classified collection. This solves the problem that the cutting device cannot switch sizes in real time for continuous cutting, achieving the effect of continuous cutting with real-time size switching.

[0049] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0050] Example 1:

[0051] like Figure 1-3As shown, this application discloses a steel pipe switching device, characterized in that it includes: a support device, which is arranged in parallel and is used for support; a cutting device, which is mounted on the support device and is used for cutting steel pipes; and a limiting device, which includes: an operating platform, which is mounted below the cutting device and connected to the support device, with sliding grooves on both sides of the operating platform, symmetrically arranged, and graduations on the outer side of the sliding grooves; and a fixing block, which is mounted on the operating platform, is trapezoidal, and has a groove in the middle for... The device includes a steel pipe holder, a square-shaped limiting block located to the left of the fixed block, with protrusions on both sides. One end of each protrusion is connected to the limiting block, and the other end is positioned within a groove on the operating table. The limiting block is used to block the steel pipe. A collecting device is located below the limiting block and is used to collect the steel pipe. The distance between the limiting block and the fixed block is adjusted by moving the protrusions on both sides of the limiting block within the groove on the operating table, thereby adjusting the length of the steel pipe to be cut. The steel pipe is then inserted into the groove of the fixed block. After the front end of the steel pipe contacts the limiting block, the cutting device is activated to complete the cutting.

[0052] Specifically, the support device also includes: a base plate, which is located at the lower end of the support device; and a support plate, which is located on the base plate. The support plate is an inverted L-shaped plate and is used to connect the cutting device and the operating table.

[0053] Specifically, the cutting device also includes: a hydraulic device mounted on a support plate and connected to the inner side of the support plate; a connecting plate mounted on the hydraulic device, with one end connected to the hydraulic device and the other end having a connecting hole; and a cutting assembly mounted on the connecting plate for cutting steel pipes. The cutting assembly is located at the other end of the connecting plate, with a motor mounted on its inner side and a cutting disc mounted on its outer side, connected through the connecting hole in the connecting plate. The cutting assembly, driven by the hydraulic device, moves the connecting plate and simultaneously moves the cutting assembly up and down to cut the steel pipe fixed on the fixed block.

[0054] Specifically, the operating platform is square and hollow, with one end open and connected to the support plate. The chute has a T-shaped structure, and length markings on the outside of the chute facilitate adjustment of the cutting length of the steel pipe. A square discharge chute is also located in the center of the operating platform, connecting the platform to the collection device.

[0055] Specifically, the grooves on the fixing blocks are circular or square, and steel pipes of different shapes can be cut by replacing the fixing blocks with different grooves. The collecting device is square and hollow.

[0056] Specifically, this application adjusts the position of the limiting block on the operating table via a sliding groove, allowing for real-time adjustment of the steel pipe's length. The steel pipe is then inserted into the groove of the fixing block, ensuring the top of the pipe contacts the limiting block. The cutting assembly then cuts the steel pipe, which falls through the unloading chute on the operating table. This process is repeated for continuous cutting. This solves the problem of the cutting device's inability to switch sizes in real-time for continuous cutting, achieving the effect of continuous cutting with real-time size switching.

[0057] Example 2:

[0058] like Figure 1-3 As shown, the fixed block is also equipped with an adjusting gear located below it. An arrow on the fixed block indicates the adjustment angle, and the adjusting gear is used to adjust the angle of the fixed block. The operating table also has corresponding gear slots, with angle markings on the outside of the slots. By rotating the fixed block, the desired beveling angle can be selected, and continuous processing can be performed in conjunction with the limiting device. First, the fixed block is rotated to bevele the steel pipe. Then, the fixed block is returned to its original position, and the steel pipe is inserted into the fixed block. The limiting device then cuts the steel pipe to its length, improving processing speed and continuity. This allows for real-time switching between the steel pipe length and beveling angle, and enables continuous processing by switching between the two cutting methods at any time.

[0059] Example 3:

[0060] like Figure 1-3As shown, the collection device also includes a collection bucket and a waste bucket. The collection bucket is located below the feeding trough. It is hollow with an opening at the top and has an inwardly recessed groove at the front. The front of the collection bucket is detachable and secured by latches at the bottom and sides. Multiple downward-sloping baffles are installed inside the collection bucket, distributed on both sides. These baffles buffer the falling steel pipes after cutting, preventing damage from impacts caused by gravity. The collection bucket and baffles effectively collect and organize the cut steel pipes, preventing them from scattering or piling on the base plate and hindering continuous cutting. This also addresses the need for time-consuming organization during or after processing, achieving the goal of continuous processing. The waste bucket is square with an opening and is located below the waste trough. The opening of the waste bucket aligns with the inclined outlet at the bottom of the waste trough. The waste bucket collects waste generated during the cutting process. The operating platform is also equipped with a waste trough, located on one side of the unloading trough. The upper end of the waste trough connects to the unloading trough, while the lower end forms an outward-sloping channel connected to a waste bin. A separating groove is provided in both the waste trough and the unloading trough, extending above the waste trough and into it. The waste trough and the unloading trough are separated by a partition plate within the separating groove. The partition plate is square, with rotating shafts at both ends, positioned within the separating groove. The partition plate's left and right positions can be adjusted to control the size of the waste trough and can be tilted to guide the cut waste into the waste bin. Through the waste bin and waste trough, the cut waste is collected uniformly, preventing it from mixing with the finished steel pipes and hindering continuous steel pipe processing. This embodiment improves the efficiency and continuity of steel pipe processing by classifying and collecting the finished steel pipes and their waste.

[0061] Example 4:

[0062] like Figure 1-3As shown, this application also includes a driving device, which comprises a sensor and a transmission assembly. The sensor is mounted on the limiting block and is used to detect whether the front end of the steel pipe is in contact with the limiting block. When the steel pipe contacts the limiting block, the hydraulic device is activated to drive the cutting assembly to cut the steel pipe. The transmission assembly further includes a transmission motor and transmission gears. The transmission assembly can be mounted on either side of the fixed block. The two ends of the transmission assembly are support frames, and two transmission gears are provided at both ends of the support frames. The transmission gears have multiple openings to increase friction and prevent the steel pipe from slipping. The distance between the transmission gears can be adjusted to accommodate steel pipes of different shapes and sizes. A transmission motor is provided on the side of the support frame, which drives the transmission gears to rotate inward, thereby moving the steel pipe toward the limiting block. In this embodiment, a transmission assembly drives the steel pipe to move inward, and a sensor detects whether the front end of the steel pipe is in position against the limiting block. When the steel pipe is in position, the transmission assembly stops rotating, and the hydraulic device is activated to drive the cutting assembly to cut the steel pipe. This eliminates the need for manual operation; the steel pipe can be fixed and processed to the same length. Furthermore, the limiting block can be adjusted synchronously during processing to switch the steel pipe length in real time, reducing manual operation time and intervals, improving the efficiency of steel pipe processing, and enhancing the continuity of steel pipe cutting, achieving continuous processing.

[0063] Example 5:

[0064] This application also discloses a method for using a steel pipe switching device, including the following steps:

[0065] To install, place the device on a horizontal surface and use a hydraulic system to raise the cutting assembly to a preset height. Then, place the collecting device under the operating table.

[0066] Adjustments are made by rotating the fixed block to select the angle at which the steel pipe needs to be cut at an angle, and by adjusting the position of the limit block on the operating table to preset the length of the steel pipe to be cut.

[0067] Cutting involves placing the steel pipe inside a fixed block, using a hydraulic device to lower the cutting assembly to make a slanted cut on the steel pipe, then inserting the steel pipe deeper until the top of the steel pipe contacts the limiting block, and then cutting the steel pipe again using the cutting assembly. This process is repeated to continuously process the steel pipe.

[0068] The cut steel pipes will be collected and fed into the collection device through the feeding chute on the operating table under the action of gravity. After being buffered multiple times by the baffles inside the collection device, they will accumulate at the bottom of the collection bucket. Meanwhile, the waste material from the oblique cutting of the steel pipes will fall into the waste bucket through the waste chute next to the feeding chute.
