Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, and in particular to a supporting follower device for pipe cutting. Background Art

[0002] The development of industry requires new requirements and standards for the processing of various profiles, especially in the laser processing industry. When processing round tubes, square tubes, rectangular tubes, channels, I-beams, and special-shaped tubes, the longer the raw material, the more likely it is that the middle part will sag under its own weight because only the two ends are clamped during cutting. Once the sag is serious, it will affect the fixtures at both ends, resulting in processing accuracy. For this reason, it is necessary to install a support device between the two fixtures to solve the problem of processing deviation caused by the sag of the profile. However, since materials such as channels, square tubes, rectangular tubes, and C-shaped steels need to be rotated on different surfaces when processed as needed, if the support device is only a fixed support, the fixture will affect the resistance to rotation and even damage the clamps and raw materials when rotating. At this time, the support device is required to be able to support force according to the needs of the work, follow the rotation according to the processing instructions, and avoid in an orderly manner when the fixture is feeding, etc., in order to meet the needs of the industry.

Its technical solution is as follows:

[0004] The present invention discloses a support follower device for pipe cutting, wherein the support follower device comprises: a transmission assembly, a support assembly A and a support assembly B, wherein the support assembly A and the support assembly B are respectively connected to the transmission assembly chain through a transmission chain A and a transmission chain B, and the transmission assembly drives the support assembly A and the support assembly B through the transmission chain A and the transmission chain B respectively to achieve support and follow-up of the cut pipe.

[0005] Wherein, the transmission assembly includes a transmission servo motor, a transmission reducer, a transmission sprocket A, a transmission sprocket B, a limit detection switch and a limit block, the transmission servo motor is drivingly connected to the transmission reducer, the transmission sprocket A and the transmission sprocket B are drivingly connected and arranged on both sides of the transmission reducer, the transmission sprocket A is connected to the transmission chain A, and the transmission sprocket B is connected to the transmission chain B; the limit detection switch is arranged on the outside of the transmission sprocket B, the limit block is arranged on the outside of the transmission sprocket A, the transmission servo motor and the transmission reducer are controllably connected to the limit detection switch and the limit block.

[0006] The support assembly A includes a tube support roller A, a sliding wheel A, a chain support roller A and a working cylinder A. The tube support roller A, the sliding wheel A and the chain support roller A are arranged in a triangular structure. The transmission chain A is fixedly connected to the tube support roller A through the chain support roller A and the sliding wheel A. The working cylinder A can controllably drive the tube support roller A to rotate around the chain support roller A; the support assembly B includes a tube support roller B, a sliding wheel B, a chain support roller B and a working cylinder B. The tube support roller B, the sliding wheel B and the chain support roller B are arranged in a triangular structure. The transmission chain B is fixedly connected to the tube support roller B through the chain support roller B and the sliding wheel B. The working cylinder B can controllably drive the tube support roller B to rotate around the chain support roller B.

[0007] Furthermore, the support assembly A also includes a support leg A and a cylinder connection and fixing block A, the lower end of the support leg A is rotatably set on the work table, the upper end of the support leg A is provided with the pipe support roller A, the cylinder connection and fixing block A is slidably mounted on the support leg A, the cylinder connection and fixing block A is connected to the piston rod of the working cylinder A, the piston rod of the working cylinder A is extended and retracted to drive the cylinder connection and fixing block A to slide up and down along the support leg A; the support assembly B also includes a support leg B and a cylinder connection and fixing block B, the lower end of the support leg B is rotatably set on the work table, the upper end of the support leg B is provided with the pipe support roller B, the cylinder connection and fixing block B is slidably mounted on the support leg B, the cylinder connection and fixing block B is connected to the piston rod of the working cylinder B, the piston rod of the working cylinder B is extended and retracted to drive the cylinder connection and fixing block B to slide up and down along the support leg B.

[0008] The working principle of a support follower device for pipe cutting of the present invention is:

[0009] When the support follower device for pipe cutting receives a support instruction, that is, when it receives a work instruction, the solenoid valve opens, the working cylinder A and the working cylinder B are ventilated, and the cylinder piston drives the pipe support roller A of the support component A and the pipe support roller B of the support component B to rise to a fixed stroke position to achieve the purpose of supporting the pipe; when the pipe needs to be rotated during processing, the support follower device for pipe cutting identifies the error between the rotating surface and the support surface of the pipe from the center under the command of the system, and the system automatically calculates and feeds back to the transmission servo motor and controls the movement of the transmission servo motor, increases the torque through the transmission reducer, and drives the transmission sprocket A, transmission chain A and transmission sprocket B, transmission chain B; the transmission chain A and the transmission chain B drive the pipe support roller A and the pipe support roller B to move up and down through the movable pulley assembly to achieve automatic support and follow-up. Because the torque of the transmission servo motor is greater than the torque of the working cylinder A and the working cylinder B, the torque is further increased by the transmission reducer to compulsorily suppress the extension and contraction of the working cylinder A and the working cylinder B. The relevant distance is limited by the limit detection switch and the limit block, so that it can support and move according to the needs. Once the feeding fixture needs to feed, the corresponding position detection switch receives the induction signal, and controls the control solenoid valve of the corresponding working cylinder to close the air under the command of the system, and the corresponding cylinder shrinks to realize the avoidance function, so as to ensure the progress of the work and realize different processing needs.

[0010] The beneficial effects of the support follower device for pipe cutting provided by the present invention are:

[0011] According to the length of the pipe, it can achieve different positions to avoid the lifting support and the rotation of the optional fixture. Under the instruction of the system instructions, it can achieve ups and downs along with the rotating surface of the profile to meet the support of the profile and follow the rotation support of the processed workpiece.
