Description

TECHNICAL FIELD

[0001] The utility model relates to laser processing technical field, specifically side hanging three -dimensional laser groove pipe cutting machine. BACKGROUND

[0002] Because laser cutting has the advantages such as smooth cutting surface, high cutting efficiency and high cutting precision, laser cutting technology has been widely applied in cutting processing technical field, and corresponding pipe cutting machine, plate cutting machine and various laser cutting equipment have appeared on the market.

[0003] Among them, the model of the existing pipe cutting machine can be divided into single chuck pipe cutting machine, two-chuck pipe cutting machine, three-chuck pipe cutting machine and four-chuck pipe cutting machine according to the number of chucks, can be divided into horizontal pipe cutting machine and side hanging pipe cutting machine according to the installation mode of the chuck, and can be divided into ordinary pipe cutting machine and groove pipe cutting machine according to the function. And because the existing two-chuck pipe cutting machine generally adopts an integral bed, the front chuck and the main chuck in the two-chuck pipe cutting machine will adopt a horizontal installation mode or a side hanging installation mode, so the existing two-chuck pipe cutting machine has a limitation in actual application: they either adopt a side hanging installation mode to enjoy the convenience of feeding, or choose a horizontal installation mode to obtain stronger stability and higher cutting precision. That is, the existing two-chuck pipe cutting machine cannot simultaneously combine the respective advantages of side hanging and horizontal installation modes, that is, it cannot ensure the convenience of feeding while achieving high stability and cutting precision. This single selection design limits its flexibility and efficiency in diversified production needs.

[0004] The existing device needs to place the pipe on the machine tool first and then convey the pipe by the machine tool when cutting the pipe, so that the pipe passes through the gantry and is cut by the laser cutting head arranged on the inner side of the gantry. However, the existing device needs to select a relatively long pipe for cutting. Such a pipe with a relatively long length will increase its weight, thereby increasing the inconvenience of manual pipe handling. In order to accurately align the pipe with the gantry part, two or more workers are needed to handle the two ends of the pipe, which wastes a lot of manpower and makes the feeding process time-consuming and laborious and difficult to accurately align. UTILITY MODEL CONTENTS

[0005] The purpose of the present application is to solve the problem that the existing pipe with a relatively long length will increase its weight, thereby increasing the inconvenience of manual pipe handling. The present application provides a side hanging three-dimensional laser groove pipe cutting machine.

Then the pipe material is cut by the laser cutting head. By adjusting the cutting angle of the laser cutting head and cooperating with the conveying of the pipe material by the conveying wheel, automatic cutting is realized. The pipe material is more convenient to load through the feeding structure, which reduces the waste of manpower and makes the loading process time-consuming and laborious and not easy to align accurately.

[0015] Further, the inside of the moving frame is fixedly connected with an electric telescopic rod, and the telescopic end of the electric telescopic rod is fixedly connected with an inclined plate.

[0016] Through the above technical scheme, the electric telescopic rod driven by starting drives the inclined plate to move upward, the upper end of the inclined plate abuts against the pipe during the rising process to drive the pipe to lift from the arc-shaped groove, and the arc-shaped groove is filled through the rising inclined plate, so that the inclined plate and the moving frame form a slope, and the pipe rolls along the inclined plate through the slope to the conveying wheels.

[0017] Further, the lower end of the portal frame is slidably provided with a collecting box, one side of the portal frame is fixedly connected with a fixed column one, the outer surface of the fixed column one is rotatably connected with a receiving plate, the outer side of the fixed column one is sleeved with a torsional spring one, and the two ends of the torsional spring one are respectively fixedly connected with the receiving plate and the portal frame.

[0018] Through the above technical scheme, the impact received by the buffer plate is conducted to the receiving plate, driving the receiving plate to rotate along the fixed column one, and the receiving plate is extruded to shrink the torsional spring one along with the rotation of the receiving plate, and the resetting force of the torsional spring one reduces the impact force.

[0019] Further, the receiving plate is fixedly connected with a receiving spring on one side, the receiving spring is fixedly connected with a buffer plate at the end, and the buffer plate is fixedly connected with an arc-shaped plate at the end.

[0020] Through the above technical scheme, the pipe falling first contacts the buffer plate, so that the buffer plate is impacted and extruded to shrink the receiving spring, and the receiving spring absorbs the vibration caused by the impact.

[0021] Further, the receiving plate is fixedly connected with a fixed column two at the end, the outer surface of the fixed column two is rotatably connected with a rotating plate, the outer side of the rotating plate is sleeved with a torsional spring two, and the two ends of the torsional spring two are respectively fixedly connected with the receiving plate and the rotating plate.

[0022] Through the above technical scheme, the arc-shaped plate falls on the rotating plate and impacts the rotating plate, so that the rotating plate rotates along the fixed column two and drives the torsional spring two to shrink, and the resetting force of the torsional spring two reduces the impact force.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1、The application, when using the device to feed the pipe, first place the pipe on the upper end of the moving frame, let the pipe fit inside the arc-shaped groove of the moving frame, then start the telescopic cylinder to drive the lifting plate to rise, let the L-shaped plate move upwards along the guide column, let the lifting plate drive the moving frame to move upwards, until the moving frame moves to a higher height than the conveying wheel, then start the drive motor to make it drive the screw to rotate, let the rotation of the screw drive the moving frame to be limited by the moving strip, and move to the other end of the lifting plate, until the one end of the moving frame abuts against the conveying wheel, at this time the electric telescopic rod is started to drive the inclined plate to move upwards, the upper end of the inclined plate abuts against the pipe to lift the pipe from the arc-shaped groove in the process of rising, and the inclined plate fills the arc-shaped groove through the rising, so that the inclined plate and the moving frame form a slope, the pipe rolls along the inclined plate through the slope to the conveying wheel, which can accurately feed the pipe when the device feeds the pipe, avoids the problem of labor lifting effort and inaccurate feeding position when manually feeding, and reduces the waste of labor.

[0025] 2、When using the device to cut the pipe, the cut-off pipe will not fall down, the falling pipe will first contact the buffer plate, so that the buffer plate is impacted and extruded to compress the receiving spring, the shock caused by the impact is absorbed by the receiving spring, at the same time, the impact on the buffer plate is transmitted to the receiving plate, driving the receiving plate to rotate along the fixed column, and the rotation of the receiving plate extrudes the torsion spring I to make it shrink, and the restoring force of the torsion spring I reduces the impact force. After receiving the buffer, the pipe rolls along the buffer plate, and falls on the rotating plate through the arc-shaped plate, impacting the rotating plate, so that the rotating plate rotates along the fixed column II and drives the torsion spring II to shrink, and the restoring force of the torsion spring II reduces the impact force. The pipe then rolls along the rotating plate and falls into the collecting box. This allows the pipe to gradually reduce the impact force when it falls after cutting, so that the impact force caused by the pipe falling into the collecting box is smaller, improving the convenience of pipe storage after cutting, and preventing the pipe from being easily damaged by rubbing.
