Description

Technical Field

[0001] The present disclosure relates to the technical field of pipe cold drawing machines, and in particular to a seamless pipe air drawing feeding device and system. Background Art

[0002] Seamless steel pipe is a long, hollow steel strip with no seams around its perimeter. The processing flow for seamless pipe includes: billet production - cutting - heating - piercing - cutting to length - hammering - pickling - lubrication - cold drawing - annealing and trimming - hydraulic pressure testing - inspection - and finally finished product.

[0003] The cold drawing process of steel pipes requires the use of a cold drawing machine. As the main processing equipment for cold-drawn steel pipes, the cold drawing machine is used to draw ferrous and non-ferrous metal pipes at room temperature and perform secondary processing on rough pipes after hot rolling and extrusion. It is the main processing equipment for producing precision, thin-walled, and high-mechanical-performance pipes.

[0004] After the cold drawing machine completes the first processing, the quality of the outer surface and the outer diameter of the seamless pipe will have large deviations. Therefore, the seamless pipe needs to be air-drawn. During air-drawing, only the outer surface of the seamless pipe needs to be processed, and the interior of the seamless pipe does not need to be processed. However, the original core-through loading workbench needs to repeat the secondary processing of the seamless pipe that has been processed inside, and repeat some other processes that are not required for air-drawing operations, which seriously affects the production rhythm. Therefore, the pipe needs to be transported separately to the air-drawing workbench for processing. The air-drawing workbench can only process a single pipe at a time. The transportation of a single pipe by manual lifting is inefficient and labor-intensive, which also seriously affects the production progress. Therefore, a new transportation method is needed to improve transportation efficiency, reduce manpower and reduce labor. Summary of the Invention

[0005] A technical problem to be solved by the present disclosure is that the existing method of conveying pipes when they are pulled out of the air is inefficient, while conveying by manual lifting is labor-intensive.

[0006] In order to solve the above technical problems, the present disclosure provides a seamless pipe air drawing feeding device, which includes:

[0007] Several placing racks are arranged at intervals, the placing racks are inclined toward the direction of gravity, and the placing racks are provided with a material storage area, a material blocking area and a material loading area in sequence;

[0008] The material blocking assembly is rotatably arranged relative to the placement rack to control the release of the pipes in the storage area;

[0009] A limiting assembly is rotatably arranged relative to the placement rack to block the pipes located in the material blocking area;

[0010] A feeding assembly is movably arranged relative to the placement frame around a first direction to lift a single pipe blocked by the limiting plate to the loading area;

[0012] In some embodiments, the aforementioned seamless pipe air-drawing feeding device, wherein the feeding assembly includes a feeding plate, a second cylinder and a second position sensor; the feeding plate is located on the side wall of the material blocking area of ​​the placement rack, and the second cylinder is connected to the feeding plate to drive the feeding plate to rotate through the extension and contraction of the second cylinder, and the second position sensor is located at one end of the material blocking area of ​​the placement rack close to the loading area, and is used to collect the position signal of the pipe to confirm the time for the next rotation of the feeding plate.

[0013] In some embodiments, in the aforementioned seamless pipe air-drawing feeding device, when the baffle plate is rotated to be set perpendicular to the placement rack, a protective layer is provided on the baffle plate.

[0014] In some embodiments, the aforementioned seamless pipe air-drawing feeding device, wherein the limiting assembly includes a limiting plate, a fixed plate and a positioning assembly; the limiting plate is located between the fixed plate and the positioning assembly, and the limiting plate is movably arranged relative to the placement rack and the fixed plate to adjust the relative position of the limiting plate and the feeding assembly, so that the feeding assembly conveys a single pipe over the limiting plate, the fixed plate is arranged between the blocking area and the feeding area, and the positioning assembly is used to fix the limiting plate.

The rotation of the rotation assembly can be controlled by an external controller to realize the transportation of the pipes. The pipes will stop being transported under the action of the limit assembly.

DETAILED DESCRIPTION

[0028] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 3 The orientation is referenced.

[0029] An embodiment of the present invention proposes a seamless pipe air-drawing feeding device comprising a plurality of racks 1, a material stopper assembly 2, a position limiting assembly 3, and a feed assembly 4. The material stopper assembly 2 controls the release of pipes from the storage area, allowing them to be released in batches, thus controlling the pipe delivery volume of a single batch. The position limiting assembly 3 blocks pipes delivered to the material stopper area, flattening them within the area, allowing the feed assembly 4 to deliver individual pipes. This invention enables mechanized and efficient pipe delivery, effectively resolving the technical problems of the prior art.

[0030] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Instead, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0031] Example 1

[0032] Reference Attachment Figure 1 , Attachment Figure 2 and attached Figure 4The material handling device of claim 1 further comprises a plurality of material handling devices, wherein the plurality of material handling devices are connected to the material handling device and the material handling device is connected to the material handling device. The plurality of material handling devices are connected to the material handling device and the material handling device is connected to the material handling device. The feeding component 4 performs the next conveying until all the pipes in the blocking area are conveyed, and then the next batch of conveying is carried out, wherein the blocking component 2 and the feeding component 4 are arranged on the side walls of the placement rack 1. When the pipes are placed on each placement rack 1, the intervals between each placement rack 1 can be conveyed by the rotating blocking component 2 and the feeding component 4, and when a single batch of processed pipes are conveyed to the storage area, the blocking component 2 will first rotate and form an angle with the placement rack 1 to store the pipes to be processed. The pipe can be released by manipulating the blocking component 2 to rotate to an angle lower than the plane of the placement rack 1, and at the same time, the angle formed by the limit component 3 and the placement rack 1 can transport the single pipe blocked by the limit component 3, completing the loading of the pipe. The present application provides a new conveying method, which does not require the use of core-threading loading and other processes during cold drawing operations, avoids repeated processing of the inner diameter, and at the same time, compared with the lifting method, it is efficient and easy to operate, thereby improving production efficiency.

[0033] Among them, the material baffle assembly 2 includes a material baffle plate 21, a first cylinder 22 and a first position sensor 23, wherein the material baffle plate 21 is a metal plate with a hard and smooth surface, and a protective layer 5 is provided on the side of the material baffle plate 21 facing the storage area of ​​the placement rack 1. It can be understood that when unloading to the storage area, the material baffle plate 21 is vertically arranged with the placement rack 1, and the pipe will hit the material baffle plate 21 when rolling. The rigid collision of metal and metal will damage the pipe and thus affect the quality of the processed product, thereby reducing the risk of damage under the protection of the protective layer 5, and a rotating shaft is provided on the material baffle plate 21, so the first cylinder 22 can be controlled to drive the material baffle plate 21 to rotate. It can be understood that the material baffle plate 21 is vertically arranged with respect to the placement rack 1. When the pipes are transported to the storage area, the first position sensor 23 detects that no pipes have passed through for a period of time. When no pipes have passed through at this stage, it means that all the pipes to be processed have been transferred to the inside of the material blocking area. Therefore, the external controller receives a signal and can control the first cylinder extension 22 to extend, and the material blocking plate 21 returns to a vertical state in preparation for the next transport.

[0034] Next, the feeding assembly 4 includes a feeding plate 41, a second cylinder 42 and a second position sensor 43. It can be understood that the pipe rolling from the storage area to the blocking area will be blocked at the limit assembly 3. When the pipe rolls to the limit assembly 3, it will first pass through the second position sensor 43. At this time, the second position sensor 43 will transmit the driving signal to the external controller, driving the second cylinder 42 to extend and retract to drive the feeding plate 41 to rotate, lifting the blocked single pipe, passing the limit assembly 3 and rolling from one side of the feeding plate 41 to the loading area to complete the transportation. The subsequent pipe will touch the other side of the feeding plate 41 and be blocked. When the feeding plate 41 is recovered to a surface below the placement rack 1 under the action of the second cylinder 42, the subsequent pipe will continue to roll along the surface of the placement rack 1 to fill the position of the last conveyed pipe, waiting for the next transportation, wherein the feeding plate 41 can only convey one pipe at a time, so the position of the limit component 3 needs to be adjusted according to the diameter of the pipe, and when the feed plate 41 rotates, the bottom of the feed plate 41 will not cross the surface of the placement rack 1, and then when the first pipe is transported and recycled, the second pipe will not affect the recycling of the feed plate 41, and the feed plate 41 will not rotate during the period when the pipe passes through the second position sensor 43 until it is blocked by the limit component 3, so as to avoid affecting the rolling of subsequent pipes. The side of the feed plate 41 close to the pipe before transportation is arc-shaped, so when the feed plate 41 conveys the first pipe but has not completely recycled it, the second pipe will touch the arc surface of the feed plate 41, and as the feed plate 41 is completely contracted, the second pipe will move along the arc surface of the feed plate 41 and then be buffered and finally blocked by the limit component 3, reducing the impact on the limit component 3 and causing damage to the pipe.

[0035] In addition, refer to the attached Figure 3 The limiting assembly 3 includes a limiting plate 31, a fixing plate 32 and a positioning assembly 33, wherein the limiting plate 31 and the fixing plate 32 are both parallelogram-shaped hard metal plates, and both extend parallel to the surface of the placement rack 1. It can be understood that, since it is necessary to meet the needs of the feeding plate 41 for single conveying of pipes, it is necessary to adjust the positional relationship between the limiting plate 31 and the edge of the feeding plate 41. The position of the limiting plate 31 on the placement rack 1 can be limited by the positioning assembly 33, and finally the limiting plate 31 is fixed by the fixing plate 32. Specifically, the positioning The component 33 includes a positioning pin 331 and a positioning seat 332. The positioning pin 331 is threadedly connected to the positioning seat 332, and the positioning seat 332 is fixedly connected to the placement rack 1. While the limit plate 31 is movably connected to the placement rack 1, it can limit the limit plate 31 by contacting the fixed plate 32 according to the force of the positioning pin 331. Therefore, after adjusting the distance that the limit plate 31 protrudes toward the material blocking area, the positioning pin 331 can be manipulated to push the limit plate 31 to contact the fixed plate 32, so as to complete the fixation of the limit plate 31, and finally cooperate with the feeding plate 41 to complete the transportation.

[0036] Next, the fixed plate 32 is fixedly connected to the placement rack 1. When the limit plate 31 no longer extends out of the fixed plate 32 in the direction of the pipe's moving path, that is, when the pipe is transported on the placement rack, it will be blocked by the fixed plate 32 to restrict movement instead of the limit plate 31. At this time, the feed plate 41 can transport the pipe with the maximum diameter at a time. When the limit plate 31 is completely extended out of the fixed plate 32 in the direction of the pipe's moving path, the feed plate 41 can transport the pipe with the minimum diameter.

[0037] Specifically, the distance between the limiting plate 31 and the fixed plate 32 can be adjusted according to the diameter of different pipes to ensure that only one pipe can be restricted between the feeding assembly 4 and the limiting plate 31 at a time. The relationship between the specific pipe diameter and the distance A between the limiting plate 31 and the fixed plate 32 is shown in Table 1 below.

[0038] Table 1: Comparison table of pipe diameter and distance between the limit plate 31 and the fixed plate 32:

[0039]

[0040] Among them, the corresponding areas of the upper limit plate 31 and the fixed plate 32 on the placement rack 1 are provided with scales, which can be adjusted according to the scales. After moving the limit plate 31 according to the corresponding pipe size, the limit plate 31 is fixed to the fixed plate 32 by rotating the positioning pin 331 to fix the position of the limit plate 31. Then, during transportation, only one pipe can be transported to the loading area at a time through the feeding component 4 to complete the transportation.

[0041] In addition, an extension plate 6 is provided in the loading area of ​​the placement rack 1. The extension plate 6 is used to shorten the distance between the cold drawing machine and the placement rack 1. It can be understood that in the actual production process, the pipe cannot be directly transported from the connecting rack 1 to the cold drawing machine for processing. Therefore, it is necessary to rotate the extension plate 6 at the end of the connecting rack 1 so that the extension plate 6 overlaps the edge of the cold drawing machine. The pipe will fall from the connecting rack 1 to the extension plate 6, and finally be transported from the extension plate 6 to the cold drawing machine to complete the transportation. At the same time, the end of the extension plate 6 is a slope, which can ensure smooth transportation of the pipe during transportation, reducing the impact of the pipe and the cold drawing machine.
