Description

Technical Field

[0001] The utility model relates to the technical field of round tube fence production, in particular to a round tube fence production device. Background Art

[0002] Fence round tube refers to the pipe used to make guardrails. Its main characteristics are round cross-section and relatively thin wall thickness. Common fence round tube materials include galvanized steel pipe, stainless steel pipe, aluminum alloy pipe, etc.

[0003] For example, the existing patent CN115139002A discloses a round tube fence production device, including a working platform, a support frame, a pipe positioning mechanism and a screw slide mechanism, the support frame is connected to the bottom of the working platform, the support frame is provided with a pipe positioning mechanism for fixing and assembling round tubes, screw slide mechanisms are installed on both sides of the working platform, the screw slide mechanism is connected to a sliding frame, the screw slide mechanism can drive the sliding frame to move, and the sliding frame is provided with a lifting assembly for controlling the lifting of the mounting block. The present invention can automatically arrange, place and assemble round tubes through the cooperation of the upper tube mechanism and the pipe positioning mechanism, and can realize complete annular welding of the round tube connection through the setting of the welding mechanism, without the need for turning over for secondary welding, reducing the welding steps, improving the overall efficiency of the round tube fence production and processing, and making the welding of the round tube connection more uniform.

[0004] A round tube fence production device designed as above has the following disadvantages in actual use: when the above device welds the fence round tube, it uses a rotary welding machine to weld the longitudinal round tube and the transverse round tube. This welding is automatic welding. If it is manual welding, there are two possibilities. One is that the welder squats down to weld the longitudinal round tube and the transverse round tube below, and squatting for a long time can easily cause the operator to suffer from lumbar muscle strain. The other is to turn over the longitudinal round tube and the transverse round tube on one side of the welding as a whole. The overall weight of the longitudinal round tube and the transverse round tube that are welded halfway is heavy, which is not convenient for the operator to flip, and the labor intensity of the operator is increased while reducing the welding efficiency. For this reason, we designed a round tube fence production device to solve the above problems. Utility Model Content

[0025] Wherein: an extension plate 7 is fixedly connected to the upper rear end surface of the shell 1, a fixed shaft 17 is rotatably connected to the left and right sides of the extension plate 7, a bidirectional threaded rod 18 is fixedly connected to the outer side of the fixed shaft 17, a moving block 19 is spirally connected to the outer side of the bidirectional threaded rod 18, a connecting rod 20 is fixedly connected to the upper end surface of the moving block 19, a clamping piece 8 is fixedly connected to the top end of the connecting rod 20, and the inner end surface of the clamping piece 8 is in contact with the outer side of the horizontal top plate 9.
