Description

Technical Field

[0001] The utility model relates to the technical field of welded pipe processing, in particular to a novel welded pipe processing device. Background Art

[0002] Welded pipe is a pipe made by welding technology, usually used to transport liquids, gases or solid particles. Welded pipes can be made of different types of metals or alloys, such as carbon steel, stainless steel, aluminum, etc. They are made by rolling metal plates or strips into a tube shape and then joining the seams through a welding process. Welded pipes have many different types and uses, including use in construction, industry, oil and gas transportation and other fields.

[0003] In the processing of welded pipes, a cutting device is required to cut them into short pipes that meet the requirements. In order to avoid the deviation of the welded pipe during the cutting process, the welded pipe needs to be fixed. However, the existing cutting devices are usually difficult to fix welded pipes of different models, and the applicability is low. In addition, the cutting disc is a consumable item and often needs to be replaced. However, the cutting disc on the existing cutting device is usually fixed by bolt connection, and the replacement efficiency is slow and inconvenient to use. Utility Model Content

[0004] The utility model aims to provide a novel welding pipe processing device which can fix welding pipes of different models and is convenient for replacing cutting pieces.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A novel welding pipe processing device includes a workbench, two arc-shaped plates are installed on the upper surface of the workbench, six guide rods are arranged through the coaxial array inside the arc-shaped plates, a pressure block is installed at one end of the guide rod, and a wedge block is installed at the other end of the guide rod, and an arc-shaped extrusion plate with a wedge-shaped cross section is arranged on the outer side of the two arc-shaped plates, and a driving mechanism capable of driving the two arc-shaped extrusion plates to move in opposite directions at the same time is arranged on the side surface of the workbench. A U-shaped frame is installed on the upper surface of the workbench between the two arc-shaped plates, an electric push rod is installed on the top of the U-shaped frame, a motor A is arranged at the end of the telescopic end of the electric push rod, a cutting blade is arranged at the end of the output shaft of the motor A, and a mounting mechanism is arranged between the cutting blade and the output shaft of the motor A.

[0007] It can be seen that when the two arc-shaped extrusion plates are driven to move inward at the same time by the driving mechanism, due to the extrusion cooperation between the arc-shaped extrusion plates and the wedge-shaped blocks, the six pressing blocks can be driven to be pressed against the outer surface of the welded pipe at the same time, so as to achieve the purpose of fixing it, and by adjusting the telescopic distance of the pressing blocks, the purpose of fixing welded pipes of different models can be achieved. It has wide applicability, and by fixing both sides of the welded pipe cutting position, the stability of the welded pipe during the cutting process can be improved. Moreover, through the setting of the mounting mechanism, the cutting disc can be quickly replaced, the replacement time of the cutting disc can be reduced, the operation efficiency can be improved, and it is easy to use.

[0008] Furthermore, the driving mechanism includes two fixed blocks respectively installed on both sides of the workbench, a threaded rod with a pair of reverse threads is rotatably connected between the two fixed blocks on one side, and the ends of the two arc-shaped extrusion plates are respectively installed on the reverse threads, a motor B is installed on the outer surface of one of the fixed blocks, the output shaft of the motor B is connected to the threaded rod, a through groove is opened inside the workbench, and a pulley group is commonly provided at the ends of the two threaded rods away from the motor B, and the pulley group passes through the inside of the through groove.

[0009] When the starting motor B drives the threaded rod connected to it to rotate, the transmission action of the pulley group can drive the other threaded rod to rotate synchronously, and due to the setting of the reverse thread, the purpose of driving the two arc-shaped extrusion plates to move inward or outward in opposite directions at the same time can be achieved. Moreover, since the two arc-shaped extrusion plates move in opposite directions, when they move away from each other, sufficient operating space can be provided near the U-shaped frame, which is convenient for cleaning the debris at the cutting site and repairing and replacing the motor A and the cutting disc.

[0010] Furthermore, the mounting mechanism includes a connecting sleeve installed on the outer surface of the cutting blade, and the output shaft of motor A is matched with the connecting sleeve, two inner grooves are provided inside the output shaft of motor A, and positioning pins are arranged inside the inner grooves.

A spring A is provided inside the inner groove, and the two ends of the spring A are respectively abutted against the inner wall of the inner groove and the positioning pin.

[0011] When removing the cutting disc, the two positioning pins can be pressed inward to shrink their ends into the connecting sleeve, and then the cutting disc can be removed from the output shaft of motor A. When installing the cutting disc, the positioning pins are also pressed inward first, and then the connecting sleeve is put on the outside of the output shaft of motor A.

[0015] Through the setting of spring B, when the arc extrusion plate squeezes the wedge block, it drives the pressure block to be pressed tightly on the weld pipe and stretches the spring B. When the arc extrusion plate moves away from the wedge block, the stretched spring B contracts inward, thereby driving the pressure block away from the outer surface of the weld pipe, thereby facilitating the taking and placing of the weld pipe.

[0016] Furthermore, side panels are provided on both sides of the outer surface of the motor A, and the upper surface of the side panels is connected to a limit rod B, and the end of the limit rod B vertically penetrates to the upper side of the U-shaped frame.

When the cutting ability of the cutting blade 109 is reduced due to wear, it can be quickly replaced through the installation mechanism 300, which reduces the replacement time of the cutting blade 109, improves the working efficiency, and is easy to use.

[0032] Specifically, the driving mechanism 200 includes two fixed blocks 201 respectively installed on the two sides of the workbench 100, a threaded rod 202 with a pair of reverse threads is rotatably connected between the two fixed blocks 201 on one side, and the ends of the two arc-shaped extrusion plates 105 are respectively installed on the reverse threads, a motor B203 is installed on the outer surface of one of the fixed blocks 201, and the output shaft of the motor B203 is connected to the threaded rod 202, a through groove 204 is opened inside the workbench 100, and a pulley group 205 is commonly provided at the ends of the two threaded rods 202 away from the motor B203, and the pulley Group 205 passes through the interior of the through groove 204.
