Description

Technical Field

[0001] The utility model belongs to the technical field of metal pipe processing, in particular to a metal pipe laser welding production line. Background Art

[0002] Metal pipe is a widely used pipeline material. Metal pipe laser welding production line is an efficient and precise metal processing equipment. It uses the high energy density characteristics of laser beam to melt and connect metal pipes. Metal pipe laser welding production line mainly consists of laser generator, beam transmission system, focusing optical device, weld tracking system, workbench and fixture, cooling system, etc. These parts work together to achieve high-precision and high-efficiency welding of metal pipes.

[0003] Announcement No. "CN222404185U" A construction metal pipe welding device relates to the field of construction technology. The construction metal pipe welding device includes a bottom plate, and two placing tables are fixedly connected to the top of the bottom plate. A pressing assembly is arranged above the two placing tables. The tops of the two placing tables are both arranged with arc-shaped grooves, and pipes are arranged in the arc-shaped grooves on the tops of the placing tables. The pressing assembly includes a top plate. The construction metal pipe welding device is provided with a pressing assembly. Specifically, after the pipe is placed on the placing table, the electric push rod is started to drive the outer rod to move downward. At this time, the U-shaped frame moves downward together, so that the transmission roller contacts the surface of the pipe. At the same time, continuous pressing causes the inner rod to drive the protrusion to squeeze the spring. At this time, the transmission roller is tightly attached to the surface of the pipe under the action of elasticity, so that the pipe can be pressed, which can reduce the warping of the pipe, thereby improving the welding accuracy and reducing the bending problem of the pipe after welding.

[0004] Although the above-mentioned utility model can reduce the warping of the pipe, thereby improving the welding accuracy and reducing the bending problem of the pipe after welding, it can only clamp cylindrical pipes. For square, rectangular, elliptical or other non-standard shaped pipes, the device cannot meet the welding requirements, which limits the application of welding devices in a wider range of fields. At the same time, it lacks sufficient flexibility and adaptability, and it is difficult to meet diversified needs, which will lead to a decrease in production efficiency and the need to frequently replace different welding devices or adjust process parameters to adapt to pipes of different shapes. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a metal pipe laser welding production line to solve the problem that only cylindrical pipes can be clamped. For square, rectangular, elliptical or other non-standard shaped pipes, the device cannot meet the welding requirements, limiting the application of welding devices in a wider range of fields. At the same time, it lacks sufficient flexibility and adaptability, making it difficult to meet diversified needs, which will lead to a decrease in production efficiency and the need to frequently replace different welding devices or adjust process parameters to adapt to pipes of different shapes.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] The metal pipe laser welding production line comprises a base, a bracket is welded on the base, a support frame is fixedly connected to the bracket, a second mounting seat is installed on one side of the support frame, a cylinder is symmetrically installed on one side of the support frame, the cylinder telescopically extends into the support frame and is fixedly connected to the first mounting seat, molds are movably connected inside the first mounting seat and the second mounting seat, mold grooves are opened on opposite sides of the mold, fixed components are symmetrically installed inside the mold, a buffer component is installed on one side of the second mounting seat, an adjustment frame is installed on the base, a mounting frame is installed on one side of the adjustment frame, a laser welding gun is installed on one side of the mounting frame, and a CCD camera is installed on the side of the adjustment frame away from the mounting frame;

[0008] The fixing component comprises a cavity, a return spring, a movable plate and a locking block. A cavity is symmetrically provided inside the mold from top to bottom. A return spring is fixedly connected to one side of the cavity, and a movable plate is fixedly connected to the other end of the return spring. The movable plate is slidably connected to the inside of the cavity. A locking block is fixedly connected to the side of the movable plate away from the return spring. One end of the locking block extends out of the mold and is provided with an inclined surface. Mounting grooves are provided on opposite surfaces of the first mounting seat and the second mounting seat. The mold and the mounting groove are plug-in. Locking grooves are symmetrically provided at the top and bottom of the mounting groove. The locking groove and the locking block are snap-connected. An unlocking block is slidably connected inside the locking groove. The unlocking block extends from the top and bottom of the first mounting seat and the second mounting seat respectively on one side away from the locking block. Limiting blocks are symmetrically fixedly connected on both sides of the unlocking block. Limiting grooves are symmetrically provided on both sides of the locking groove. The limiting blocks are slidably connected to the limiting grooves. The requirements for welding metal pipes of different specifications or types are flexibly adapted, the time and downtime required for replacing the mold are reduced, the overall production efficiency is improved, and when the mold is damaged, only the mold itself can be replaced without large-scale repair of the entire welding device, thereby reducing maintenance costs.

[0009] As a preferred technical solution, the buffer assembly includes a buffer seat, a buffer plate, a first limiting column, a built-in hole, a first buffer spring and a second limiting column. A buffer groove is symmetrically provided on one side of the second mounting seat, and a buffer plate is slidably connected inside the buffer groove. One side of the buffer plate and the bottom of the buffer groove are fixedly connected to the buffer seat. One side of the buffer seat inside the buffer groove is fixedly connected to the first limiting column. A built-in hole is provided on the other side of the first limiting column. One end of the built-in hole close to the bottom of the buffer groove is fixedly connected to the first buffer spring. The other end of the first buffer spring is fixedly connected to the second limiting column. The second limiting column and the inside of the built-in hole are slidably connected. The first and second limit posts are dynamically connected, and the other side of the second limit post is fixedly connected to the buffer seat on the buffer plate. A second buffer spring is sleeved on the outside of the first limit post and the second limit post. The head and tail ends of the second buffer spring are respectively fixedly connected to the opposite surfaces of the buffer seat. A buffer post is symmetrically fixedly connected to one side of the first mounting seat. The buffer post and the buffer groove are plug-in, which can effectively reduce the direct pressure of the clamping assembly on the metal pipe, prevent the pipe from being deformed or damaged due to excessive force during the clamping process, and ensure that the metal pipe can maintain a stable position and posture during the welding process, thereby improving the welding accuracy and consistency.

[0010] As a preferred technical solution, a protective pad is glued inside the mold groove. The protective pad is made of soft rubber, which can reduce direct friction and collision between the workpiece and the mold groove, thereby extending the service life of the mold groove and welding equipment.

[0011] In summary, the utility model mainly has the following beneficial effects:

[0012] First, in the present invention, the mold is inserted into the mounting grooves of the first mounting seat and the second mounting seat respectively. During the insertion process, the extrusion force applies pressure to the inclined surface of one end of the locking block, so that the locking block drives the movable plate to press against the reset spring, the reset spring is compressed, and the locking block retracts into the cavity. When the locking block moves to the locking groove, the reset spring is reset, the movable plate rebounds and drives the locking block to pop out, and the locking block is fixed with the locking groove to complete the installation of the mold. It can flexibly adapt to the welding needs of metal pipes of different specifications or types, reduce the time and downtime required for changing the mold, improve the overall production efficiency, and only the mold itself can be replaced when the mold is damaged, without the need for large-scale repair of the entire welding device, thereby reducing maintenance costs;

[0013] Second, in the utility model, the pipe is placed inside the die groove of the mold, and then the cylinder is started to control the first mounting seat to move toward the second mounting seat, so that the first mounting seat and the second mounting seat are fitted together, and at the same time the buffer column is inserted into the buffer groove, and the buffer column presses against the buffer plate, so that the buffer plate drives the second limiting column to slide inside the built-in hole of the first limiting column, and the second limiting column presses against the first buffer spring, and the first buffer spring and the second buffer spring are compressed at the same time to absorb and disperse the impact force when they are combined, which can effectively reduce the direct pressure of the clamping assembly on the metal pipe, prevent the pipe from being deformed or damaged due to excessive force during the clamping process, and can also ensure that the metal pipe can maintain a stable position and posture during the welding process, thereby improving the welding accuracy and consistency.
