Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, specifically to a pipe processing equipment and its processing technology. Background Technology

[0002] Posts are the components that provide fixed support for corrugated guardrail panels. They absorb the energy generated during a vehicle collision, thus mitigating the enormous instantaneous energy produced by the vehicle. Posts are an indispensable component of guardrail products and are widely used in guardrails, decorative designs, and safety protection accessories in industrial production, agriculture, municipal engineering, and transportation sectors, with a large market demand.

[0003] Our company manufactures 130mm square tube columns, primarily using a cold saw cutting line for cutting and punching (the raw tubes are generally quite long and need to be cut to the required length before use). After cold sawing, punching is performed directly; that is, after the cold saw cuts the tubes, a conveyor belt transports the slit tubes to the punching equipment. After punching, this processing step is complete. This method is highly efficient and suitable for mass production. However, in subsequent production processes and based on feedback from purchasing companies, we have discovered some issues: firstly, some tubes exhibit precision errors during installation, affecting installation speed; secondly, a small number of tubes show abnormal corrosion rates, requiring individual maintenance and increasing labor and material costs. Summary of the Invention

[0004] This invention provides a pipe processing equipment and its processing technology to solve the technical problems in the prior art.

[0005] To solve the above problems, the pipe processing equipment provided by the present invention adopts the following technical solution: it includes a cold saw, which is used to cut pipes, and the direction of pipe travel is defined as forward; The punching equipment is located in front of the cold saw and is used to punch holes in pipes. Also includes: A roller conveyor line, located in front of the punching equipment, is used to transport pipes. A reversing mechanism is installed on the roller conveyor line for reversing the direction of the pipe. The reversing mechanism includes a lifting structure for driving the pipe to rise and a reversing structure for gripping and rotating the pipe to change its direction. The lifting structure has a clearance position and a working position in its lifting stroke. When in the clearance position, the lifting structure retracts to the bottom of the roller conveyor or is flush with the roller conveyor to avoid the pipe and allow the pipe to pass normally. When in the working position, the lifting structure lifts the pipe so that the reversing structure can grab the pipe for reversing.

[0006] As a further improvement, the front end of the roller conveyor is provided with a retractable material stop mechanism.

[0007] As a further improvement, the material blocking mechanism includes a telescopic cylinder and a baffle connected to the output end of the telescopic cylinder.

[0008] As a further improvement, the lifting structure includes at least two lifting cylinders arranged in the front-to-back direction, and a positioning seat is fixedly connected to the top of the lifting cylinder.

[0009] As a further improvement, the reversing structure includes a support frame spanning the roller conveyor line, with grippers for gripping pipes located above the roller conveyor line. The grippers are mounted on the support frame via a slewing bearing, and a servo motor for driving the grippers to rotate is fixedly mounted on the top of the support frame.

[0010] As a further improvement, at least two grippers are provided, and the grippers are electric grippers or pneumatic grippers.

[0011] The present invention also provides a pipe processing technology, which uses the above-mentioned pipe processing equipment and includes the following steps: S1. Raw material conveying; S2. Cold sawing: The pipe is transported to the bottom of the cold saw equipment, and the cold saw equipment cuts the pipe. S3. Segmented processing: The first section of the column after sawing is conveyed to the roller conveyor line, while the other columns are directly conveyed to the punching equipment for punching. S4. Reversal: The first column is conveyed to the reversal structure via the roller conveyor line. The lifting structure lifts the first column so that the top of the first column is inside the gripper. After the gripper grabs the first column, the lifting structure descends. The servo motor drives the gripper to rotate 180°, so that the first column changes direction. S5. Reverse conveying: After the first column is reversed, the lifting structure rises, lifting the first column down onto the roller conveyor line. The roller conveyor line runs in reverse, conveying the first column to the punching equipment for punching.

[0012] The beneficial effects of the above-described technical solution of the present invention are as follows: This invention improves product consistency by optimizing pipe processing equipment and processes, and essentially eliminates the current problems of installation difficulties and abnormal pipe corrosion.

[0013] After the pipe is sawn, the first section of the column is conveyed to the reversing mechanism via a roller conveyor to change direction, thus ensuring that the punched end and the cut end of all columns are on the same end. The cut surface of the cold saw is flat, with no thermal deformation and few burrs on the cut end face. Using the cut end face as the reference end face, there will be virtually no problems such as misaligned holes or bolts not being able to be inserted during subsequent on-site assembly, which greatly improves the convenience of on-site installation.

[0014] Since both the punching and cutting ends are on the same end, corrosion protection can be completed in one go, avoiding situations where the corrosion protection of the punching or cutting ends is inadequate or missed. This reduces production steps, ensures product quality, and reduces the risk of rust. Attached Figure Description

[0015] The above and other objects, features, and advantages of exemplary embodiments of the present invention will become readily apparent upon reading the following detailed description with reference to the accompanying drawings. In the drawings, several embodiments of the invention are illustrated by way of example and not limitation, and like or corresponding reference numerals denote like or corresponding parts, wherein: Figure 1 This is a schematic diagram of the main structure of the pipe processing equipment of the present invention; Figure 2 This is a top view of the pipe processing equipment of the present invention; Figure 3 This is a process flow diagram of the pipe processing technology of the present invention.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Currently, our company's 130mm square tube columns are mainly produced through cold saw cutting and punching. Subsequent feedback from the buyer indicates two issues: firstly, some pipes exhibit precision errors during installation, affecting installation speed; secondly, a small number of pipes show abnormal corrosion rates, requiring individual maintenance and increasing labor and material costs.

[0019] To address these issues, we analyzed our existing production process and found that the main problem lies in the cold sawing stage. Currently, the raw material needs to be cut into two sections to form two columns. After punching holes in the two columns, subsequent anti-corrosion and other processes are performed. This leads to a problem: the cold saw cuts the pipe in half, and the punching equipment is fixed (the force required for punching the pipe is significant; if a sliding connection were used, precision issues would arise). This results in one column inevitably having a misaligned punched and cut end. During on-site installation, the cut end is relatively flat, while the non-cut end of the column may have uneven surfaces or other precision errors, potentially causing misalignment during installation. Furthermore, anti-corrosion treatment typically focuses on the punched end, meaning one column cannot simultaneously cover both the punched and cut ends. Reworking the process would increase costs and processing time, so a simple anti-corrosion treatment is usually applied to the other end, leading to abnormal rust on a small number of columns.

[0020] To address the aforementioned issues, the inventive concept of this invention is as follows: After the pipe is cut, the first section of the column continues to be output forward via a roller conveyor line and undergoes a reversal operation. Simultaneously, the tail end column is punched. Once the tail end column is punched, the roller conveyor line reverses the direction of the first section of the column and transports it to the punching equipment. The steps are relatively compact, enabling continuous operation. The fully automatic reversal not only ensures production efficiency but also avoids the safety hazards of manual reversal, reducing occupational hazards.

[0021] By performing the above operations, it can be ensured that all the punched and cut ends of the columns are on the same end, which improves the corrosion resistance of the product and the convenience of on-site installation.

[0022] After introducing the basic principles of the present invention, various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0023] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0024] Example 1 of the pipe processing equipment and processing technology provided by the present invention: like Figure 1 and Figure 2 As shown, the pipe processing equipment includes a cold saw, a punching machine, a roller conveyor line 200, and a reversing mechanism 300.

[0025] Cold saw equipment is used to cut pipes, with the direction of pipe travel defined as forward; The punching equipment is located in front of the cold saw and is used to punch holes in pipes. The cold saw and punching equipment are not shown in the figure. Both the cold saw and punching equipment are existing technologies, and no improvements have been made to the cold saw and punching equipment in this embodiment. Therefore, their structures will not be described in detail here.

[0026] The roller conveyor 200 is set in front of the punching equipment and is used to transport pipes. The roller motor 410 of the roller conveyor 200 is set below the end of the roller conveyor 200. The roller motor 410 drives the roller conveyor 200 to run through the chain 420. Since the roller conveyor 200 also needs to transport in reverse, the roller motor 410 needs to be a motor that can be reversed.

[0027] The front end of the roller conveyor 200 is equipped with a retractable material blocking mechanism 100, which includes a telescopic cylinder and a baffle connected to the output end of the telescopic cylinder. The material blocking mechanism 100 serves both to block material and to position it.

[0028] A reversing mechanism 300 is disposed on the roller conveyor line 200 for reversing the direction of the pipe. The reversing mechanism 300 includes a lifting structure 320 for driving the pipe to rise and a reversing structure for gripping and rotating the pipe to change its direction. Since there is a gap between the rollers of the roller conveyor line 200, the lifting structure 320 is disposed in the gap between the rollers.

[0029] The lifting structure 320 has a clearance position and a working position in its lifting stroke. When in the clearance position, the lifting structure 320 retracts to below or flush with the roller conveyor line 200 to allow the pipe to pass normally. When in the working position, the lifting structure 320 lifts the pipe so that the reversing structure can grab the pipe for reversing.

[0030] In this embodiment, the lifting structure 320 includes two lifting cylinders, which are arranged in the front-to-back direction, and a positioning seat is fixedly connected to the top of the lifting cylinder.

[0031] The reversing structure includes a support frame spanning the roller conveyor line 200. Above the roller conveyor line 200, there is a gripper 313 for gripping the pipe. The gripper 313 is mounted on the support frame via a slewing bearing 311. A servo motor 312 for driving the gripper 313 to rotate is also fixedly mounted on the top of the support frame.

[0032] Two grippers 313 are provided to ensure the stability of gripping. The grippers 313 are either electric grippers 313 or pneumatic grippers 313.

[0033] like Figure 3 As shown, this embodiment also provides a pipe processing technology, which uses the above-mentioned pipe processing equipment and includes the following steps: S1. Raw material conveying; S2. Cold sawing: The pipe is transported to the bottom of the cold saw equipment, and the cold saw equipment cuts the pipe. S3. Segmented processing: The first section of the column after sawing is conveyed to the roller conveyor line 200, and the other columns are directly conveyed to the punching equipment for punching processing. S4. Reversal: The first column is conveyed to the reversal structure via the roller conveyor 200. The lifting structure 320 lifts the first column so that the top of the first column is inside the gripper 313. After the gripper 313 grabs the first column, the lifting structure 320 descends. The servo motor 312 drives the gripper 313 to rotate 180°, so that the first column changes direction. S5. Reverse conveying: After the first column is reversed, the lifting structure 320 rises, lifting the first column and lowering it onto the roller conveyor line 200. The roller conveyor line 200 then reverses its direction, conveying the first column to the punching equipment for punching.

[0034] While various embodiments of the invention have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and essence of the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed in the practice of the invention. The appended claims are intended to define the scope of the invention and therefore cover any modular compositions, equivalents, or alternatives within the scope of these claims.
