Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, specifically to an automated pipe processing and manufacturing production line and process. Background Technology

[0002] Pipe manufacturing typically involves processes such as rust removal, cutting, welding, and marking to ensure that the produced pipes meet the requirements for use.

[0003] However, in the existing processes of rust removal, cutting, welding, and marking of pipelines, the pipelines need to be manually moved from the previous station to the next station and aligned each time a process is switched. Since pipelines are usually quite heavy, manually moving the pipelines after each process is completed is not only time-consuming and labor-intensive, reducing work efficiency, but also requires realignment after each placement at the next station, further increasing the workload. Therefore, it is necessary to improve this defect.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0005] The purpose of this invention is to provide an automated pipeline processing and manufacturing production line and process to solve the problem mentioned in the background art that pipeline processing in the prior art requires manual handling and alignment of pipelines every time the processing station is switched, which is time-consuming and labor-intensive, and the pipelines need to be re-aligned every time the station is switched.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automated pipeline processing and manufacturing production line includes a base plate, pipe fittings located above the base plate, and a rust removal assembly, a cutting assembly, a welding assembly, and a marking assembly sequentially arranged on the upper end of the base plate. It also includes:

[0008] The conveying assembly is slidably mounted on the upper end of the base plate and is used to sequentially convey the rust removal assembly, cutting assembly, welding assembly, and marking assembly of the pipe fittings for processing.

[0009] The first support component and the second support component are alternately disposed on the upper part of the conveying component to alternately support the pipe components.

[0010] Furthermore, the transmission component includes:

[0011] The bracket is fixedly connected to the upper end of the base plate;

[0012] The first drive motor is fixedly connected to the upper end of the base plate and located at the initial end of the bracket;

[0013] One end of the screw is fixedly connected to the drive end of the drive motor, and the other end is rotatably inserted into the end of the bracket.

[0014] The support platform is slidably disposed on the upper end of the base plate, and the lower end of the support platform is threadedly connected to the outside of the screw through a push block.

[0015] Furthermore, the first support component includes:

[0016] The base has two sets, which are fixedly connected to the upper end of the support platform;

[0017] A lifting platform is provided above the base, and a first cylinder for driving the lifting platform to move up and down is provided at the lower end of the lifting platform and inside the base.

[0018] The second drive motor is installed inside the lifting platform;

[0019] The active roller is rotatably connected to the upper end of the lifting platform and is used to drive the pipe fittings to rotate. The active roller is connected to the drive end of the second drive motor via a belt.

[0020] The driven roller is rotatably connected to the upper end of the lifting platform and located on one side of the driving roller, and is used to cooperate with the driving roller to support the pipe fittings.

[0021] Furthermore, the second support component includes:

[0022] The support rods are provided in two sets and are fixedly connected to the upper end of the support platform;

[0023] The second cylinder is installed on one side of the support rod;

[0024] A rubber block is fixedly connected to the upper end of the second cylinder and is used to lift the pipe fittings.

[0025] A limiting groove is provided at the upper end of the rubber block to initially limit the pipe fitting and increase the friction between the rubber block and the pipe fitting.

[0026] Furthermore, a stop bar is fixedly connected to the upper end of the support rod. There are two sets of stop bars, located on both sides of the pipe fitting, for limiting the position of the pipe fitting.

[0027] Furthermore, the rust removal assembly includes a first frame connected to the side of the base plate and a grinding machine installed on the inner wall of the upper end of the first frame for rust removal and grinding of the pipe fittings.

[0028] The cutting assembly includes a second frame connected to the side of the base plate and a cutting machine installed on the inner wall of the upper end of the second frame for cutting pipe fittings.

[0029] The welding assembly includes a third frame connected to the side of the base plate and an electric welding machine installed on the inner wall of the upper end of the third frame for welding pipe fittings.

[0030] The marking assembly includes a fourth frame connected to the side of the base plate and a laser marking machine installed on the inner wall of the upper end of the fourth frame for marking pipe fittings.

[0031] Furthermore, the grinding machine, cutting machine, welding machine, and laser marking machine are positioned on the same straight line and between the two sets of stop bars, in order to prevent collisions with the stop bars when processing the pipe fittings between them.

[0032] Furthermore, the present invention also provides an automated pipeline processing and manufacturing production line for pipeline processing, characterized by comprising the following steps:

[0033] In the feeding process, the pipe fitting is placed on the upper part of the first support component or the second support component, and the conveying component delivers the pipe fitting directly below the rust removal component.

[0034] In the rust removal process, the first support component lifts the pipe fitting upwards, so that the pipe fitting is lifted to contact the grinding machine. At this time, the grinding machine grinds the surface of the pipe fitting. The active roller drives the pipe fitting to rotate and switch the circumferential grinding position. The conveying component drives the pipe fitting to move in the direction of the cutting component to switch the axial grinding position of the pipe fitting. After the rust removal work is completed, the first support component drives the pipe fitting to move downwards to the initial height.

[0035] In the cutting process, the conveying component delivers the pipe component directly below the cutting component, and the second support component lifts the pipe component upward, so that the pipe component is separated from the first support component and the position of the pipe component to be cut contacts the cutting machine. The cutting machine cuts the pipe component. Subsequently, the second support component moves the pipe component downward to the initial height.

[0036] In the welding process, the conveyor assembly delivers the cut pipe fitting directly below the welding assembly. The second support assembly lifts the pipe fitting upwards, positioning the area to be welded according to the welding requirements. Welding is then performed on the pipe fitting. Subsequently, the second support assembly moves the pipe fitting downwards to its initial height.

[0037] In the marking process, the conveyor component delivers the welded pipe fitting directly below the marking component, so that the position on the pipe fitting to be marked is opposite to the laser marking machine, and the laser marking machine performs the marking work on the pipe fitting.

[0038] During the unloading process, the conveying component moves the marked pipe fittings out from directly below the marking component. At this time, the workers unload the pipes from the top of the first or second support component.

[0039] Compared with the prior art, the beneficial effects of the present invention are:

[0040] 1. This invention employs a first support assembly to lift the pipe fittings during rust removal, ensuring that the rotating active roller drives the pipe fittings to rotate during the rust removal process, thereby automatically switching the grinding and rust removal position. During cutting and welding, a second support assembly lifts the pipe fittings, utilizing the friction between the pipe fittings through the limiting grooves to prevent the pipe fittings from rotating during cutting and welding, thus avoiding a decrease in cutting and welding accuracy. This eliminates the need for workers to re-align the pipe fittings each time a workstation is switched, greatly improving the efficiency of pipe processing.

[0041] 2. This invention integrates the rust removal, cutting, welding, and marking processes in a straight line. The position switching of pipe components between different processes can be completed simply by controlling the conveying component to transport the pipe components. The entire processing process does not require manual handling of pipe components multiple times, resulting in high work efficiency. Attached Figure Description

Detailed Implementation

[0050] 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.

[0051] Example 1

[0052] Please see Figure 1-6 The present invention provides a technical solution:

[0053] An automated pipeline processing and manufacturing production line includes a base plate 100, a pipeline component 101 located above the base plate 100, and a rust removal assembly 4, a cutting assembly 5, a welding assembly 6, and a marking assembly 7 sequentially arranged on the upper end of the base plate 100. The line also includes:

[0054] The conveying component 1 is slidably disposed on the upper end of the base plate 100 and is used to sequentially convey the rust removal component 4, the cutting component 5, the welding component 6, and the marking component 7 to the pipe fitting 101 for processing.

[0055] The first support component 2 and the second support component 3 are alternately disposed on the upper part of the conveying component 1 to alternately support the pipe component 101.

[0056] As an improvement, such as Figure 1-2 As shown, the transmission component 1 includes:

[0057] The bracket 11 is fixedly connected to the upper end of the base plate 100;

[0058] The first drive motor 12 is fixedly connected to the upper end of the base plate 100 and located at the initial end of the bracket 11;

[0059] One end of the screw 13 is fixedly connected to the drive end of the drive motor, and the other end is rotatably inserted into the end of the bracket 11.

[0060] The support platform 14 is slidably disposed on the upper end of the base plate 100, and the lower end of the support platform 14 is threadedly connected to the outside of the screw 13 via a push block 141.

[0061] Furthermore, such as Figure 3 As shown, the first support component 2 includes:

[0062] The base 21 has two sets and is fixedly connected to the upper end of the support platform 14;

[0063] A lifting platform 23 is located above the base 21, and a first cylinder 22 for driving the lifting platform 23 to lift and lower is provided at the lower end of the lifting platform 23 and inside the base 21.

[0064] The second drive motor 24 is installed inside the lifting platform 23;

[0065] The active roller 26 is rotatably connected to the upper end of the lifting platform 23 and is used to drive the pipe component 101 to rotate. The active roller 26 is connected to the drive end of the second drive motor 24 via a belt 25.

[0066] The driven roller 27 is rotatably connected to the upper end of the lifting platform 23 and located on one side of the driving roller 26, and is used to cooperate with the driving roller 26 to support the pipe component 101.

[0067] As an improvement, such as Figure 2-4 As shown, the second support component 3 includes:

[0068] Support rod 31, provided in two sets, is fixedly connected to the upper end of the support platform 14;

[0069] The second cylinder 33 is installed on one side of the support rod 31;

[0070] Rubber block 34 is fixedly connected to the upper end of the second cylinder 33 and is used to lift the pipe fitting 101.

[0071] A limiting groove 35 is provided on the upper end of the rubber block 34 to initially limit the pipe fitting 101 and increase the friction between the rubber block 34 and the pipe fitting 101.

[0072] Among them, the rubber block 34 is made of rubber material and is used to further increase the friction between the limiting circular groove 35 and the pipe component 101, so as to prevent the pipe component 101 from rotating during the cutting and welding process, which would reduce the accuracy of cutting and welding.

[0073] Furthermore, such as Figure 4As shown, a stop bar 32 is fixedly connected to the upper end of the support rod 31. The stop bar 32 is provided in two sets, located on both sides of the pipe fitting 101 respectively, and is used to limit the pipe fitting 101.

[0074] Furthermore, such as Figure 1 , Figure 6 As shown, the rust removal assembly 4 includes a first frame 41 connected to the side of the base plate 100 and a grinder 42 installed on the inner wall of the upper end of the first frame 41 for rust removal and grinding of the pipe fitting 101.

[0075] The cutting assembly 5 includes a second frame 51 connected to the side of the base plate 100 and a cutting machine 52 installed on the inner wall of the upper end of the second frame 51 for cutting the pipe fitting 101.

[0076] The welding assembly 6 includes a third frame 61 connected to the side of the base plate 100 and an electric welding machine 62 installed on the inner wall of the upper end of the third frame 61 for welding the pipe fitting 101.

[0077] The marking assembly 7 includes a fourth frame 71 connected to the side of the base plate 100 and a laser marking machine 72 installed on the inner wall of the upper end of the fourth frame 71 for marking the pipe fitting 101.

[0078] The grinding machine 42, cutting machine 52, welding machine 62, and laser marking machine 72 are on the same straight line and located between the two sets of stop bars 32, which is used to avoid collision with the stop bars 32 when processing the pipe fitting 101 between the stop bars 32.

[0079] It should be added that the height of the plane at the upper end of the stop bar 32 in this invention is higher than the height of the grinder 42, the cutter 52, and the welder 62, to ensure that the pipe fitting 101 is always located between the two sets of stop bars 32 after it is lifted.

[0080] It should be noted that in the specific implementation process of the present invention, initially, the rubber block 34 and the active roller 26 are at the same height, and the pipe component 101 is placed on the upper end of the two sets of rubber blocks 34 and located inside the limiting circular groove 35. At this time, the pipe component 101 is located in the upper gap between the active roller 26 and the driven roller 27, and the outer side of the pipe component 101 is in contact with the active roller 26 and the driven roller 27.

[0081] like Figure 1-3As shown, the first drive motor 12 is started, which drives the screw 13 to rotate. The screw 13, under the action of the thread tangential force between itself and the push block 141, drives the push block 141 to move. The push block 141, through the support platform 14, drives the first support assembly 2 and the second support assembly 3 to move synchronously towards the rust removal assembly 4, so that the pipe fitting 101 is sent directly below the rust removal assembly 4. Then, the first cylinder 22 is started, which drives the pipe fitting 101 upward through the lifting platform 23, so that the initial end of the pipe fitting 101 contacts the grinding roller of the grinder 42. The grinder 42... The pipe fitting 101 is ground. The second drive motor 24 is started. The second drive motor 24 drives the active roller 26 to rotate through the belt 25. The active roller 26 drives the pipe fitting 101 to rotate through friction between the active roller 26 and the pipe fitting 101, so that the pipe fitting 101 can switch the circumferential grinding position. At the same time, the first drive motor 12 drives the push block 141 to move continuously, so that the axial grinding position of the pipe fitting 101 is continuously switched. After the grinding is completed, the first cylinder 22 drives the pipe fitting 101 to move downward to the initial height, thereby realizing the automatic rust removal of the pipe.

[0082] like Figure 6 As shown, subsequently, under the driving action of the first drive motor 12, the pipe component 101 is conveyed to the area directly below the cutting assembly 5, and the second cylinder 33 is activated. The second cylinder 33 drives the pipe component 101 upward through the rubber block 34, so that the position of the pipe component 101 to be cut is lifted to contact the cutting machine 52. The cutting machine 52 cuts the pipe component 101. After the cutting is completed, the second cylinder 33 drives the pipe component 101 downward to the initial height.

[0083] Subsequently, under the driving action of the first drive motor 12, the pipe component 101 is transported to the underside of the welding assembly 6, and the second cylinder 33 is activated. The second cylinder 33 drives the pipe component 101 upward through the rubber block 34, so that the position of the pipe component 101 to be welded is lifted to contact the electric welding 62. The electric welding 62 performs welding work on the pipe component 101. After the welding work is completed, the second cylinder 33 drives the pipe component 101 downward to the initial height.

[0084] Finally, under the driving action of the first drive motor 12, the pipe component 101 is conveyed to the area directly below the marking assembly 7, so that the position of the pipe component 101 to be marked corresponds to the laser marking machine 72, and the laser marking machine 72 performs the marking work on the pipe component 101.

[0085] like Figure 2-5As shown, in this invention, during the rust removal process, the first support component 2 lifts the pipe component 101, ensuring that the rust removal process can be driven by the rotating active roller 26 to rotate the pipe component 101, thereby automatically switching the grinding and rust removal position. During the cutting and welding processes, the second support component 3 lifts the pipe component 101, and the friction between the pipe components 101 using the limiting circular groove 35 prevents the pipe component 101 from rotating during the cutting and welding processes, thus avoiding a decrease in cutting and welding accuracy. Therefore, the pipe component 101 does not need to be repositioned by the worker each time the work position is changed, which greatly improves the efficiency of pipe processing.

[0086] Example 2

[0087] like Figure 1-7 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0088] The automated pipe processing and manufacturing production line according to Embodiment 1 is used for the production process of pipe processing, including the following steps:

[0089] In the feeding process, the pipe fitting 101 is placed on the upper end of the first support component 2 or the second support component 3, and the conveying component 1 delivers the pipe fitting 101 directly below the rust removal component 4.

[0090] In the rust removal process, the first support component 2 lifts the pipe component 101 upwards, so that the pipe component 101 is lifted to contact the grinding machine 42. At this time, the grinding machine 42 grinds the surface of the pipe component 101. The active roller 26 drives the pipe component 101 to rotate and switch the circumferential grinding position. The conveying component 1 drives the pipe component 101 to move towards the cutting component 5 to switch the axial grinding position of the pipe component 101. After the rust removal work is completed, the first support component 2 drives the pipe component 101 to move downwards to the initial height.

[0091] In the cutting process, the conveying component 1 delivers the pipe component 101 directly below the cutting component 5, and the second support component 3 lifts the pipe component 101 upward, so that the pipe component 101 is separated from the first support component 2 and the position of the pipe component 101 to be cut contacts the cutting machine 52. The cutting machine 52 cuts the pipe component 101. Subsequently, the second support component 3 drives the pipe component 101 to move downward to the initial height.

[0092] In the welding process, the conveying component 1 delivers the cut pipe component 101 directly below the welding component 6. The second support component 3 lifts the pipe component 101 upwards, positioning the area to be welded on the pipe component 101 to correspond with the welding 62. The welding 62 is then used to weld the pipe component 101. Subsequently, the second support component 3 moves the pipe component 101 downwards to its initial height.

[0093] In the marking process, the conveying component 1 delivers the welded pipe fitting 101 directly below the marking component 7, so that the position on the pipe fitting 101 to be marked is opposite to the laser marking machine 72, and the laser marking machine 72 performs the marking work on the pipe fitting 101.

[0094] In the unloading process, the conveying component 1 transfers the marked pipe fitting 101 from directly below the marking component 7. At this time, the workers unload the pipe from the top of the first support component 2 or the second support component 3.

[0095] It should be noted that the present invention integrates the rust removal process, cutting process, welding process and marking process in a straight line. The position switching of the pipe component 101 between different processes can be completed by controlling the conveying component 1 to convey the pipe component 101. The entire processing process does not require manual handling of the pipe component 101 multiple times, resulting in high work efficiency.

[0096] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
