Description

Technical Field

[0001] The utility model belongs to the technical field of round tube processing, in particular to a round tube closing machine. Background Art

[0002] Round tube refers to a steel material with two ends open and a hollow concentric cross section, and a large ratio of length to circumference. It is an economical steel material with a light weight when the bending and torsional strength are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures. The specifications of metal round tubes are expressed by the outer dimensions, inner diameter and wall thickness, and the size range is very wide. During the processing of round tubes, a closing machine is generally required to close the ends of the round tubes.

[0003] The current method of closing the ends of round tubes is usually to first clamp the round tube with a pneumatic clamp, heat the end of the round tube with an electric heating wire, and then push the grinding block to move with a telescopic cylinder. At this time, the pneumatic clamp is driven by a motor to rotate the round tube, and then the grinding block is rotated and moved so that the end of the round tube can be closed by the grinding block.

[0004] However, there are still some shortcomings in actual use. The most obvious one is that after the round tube closing process is completed, it is usually necessary to wait for the round tube to cool down, and the staff must use a clamp to remove the round tube from the pneumatic clamp before putting in a new round tube for closing processing. This is inconvenient for the discharge of the round tube and reduces the processing efficiency of the round tube closing machine. For this reason, we propose a round tube closing machine.

Since the two sets of movable rods are threadedly connected to the two ends of the bidirectional screw and slide in the movable frame, the bidirectional screw can drive the movable rod and the clamping block to move relative to each other when rotating, and the round tube is clamped by the clamping block.

At this time, the clamping block releases the round tube, allowing the round tube to fall into the storage box, thereby facilitating the discharge of the round tube and improving the processing efficiency of the round tube closing machine.
