[0002] A pipe rolling letter machine is a special equipment for rolling out letters, patterns or codes on the surface of a pipe. It is usually composed of a rolling head and a driving mechanism. The rolling head is engraved with reverse letters or patterns. When the rolling head rolls on the surface of the pipe, the letters or patterns are pressed on the pipe through pressure and friction. The pipe rolling letter machine is widely used in pipe identification and traceability management in the petroleum, chemical, natural gas and water industries.

One end of the rolling letter base is provided with a second hydraulic cylinder, which is fixedly arranged at one end of the limiting track and has an extension direction parallel to the length direction of the limiting track. A plurality of letter grooves are arranged in parallel along the width direction of the letter die, and a plurality of letter blocks with the same size are arranged in each letter groove. The letter blocks are detachably arranged on the letter die. In actual application, the letter blocks are mounted on the letter die, the letter die is mounted on the rolling letter base, the workpiece to be marked is placed on the support seat, the first hydraulic cylinder is controlled to drive the limiting track to move downward so that the letter die is in contact with the workpiece, and then the second hydraulic cylinder is controlled to drive the rolling letter base to move along the length direction of the limiting track, so as to mark letters on the workpiece.

[0004] In the above-mentioned technology, the first hydraulic cylinder can control the height of the limiting track and the rolling letter base, and adjust the depth of lettering.

[0005] In order to improve the problem that the effect of lettering on the pipe by the rolling letter machine in the related art is poor, the present application provides a rolling letter machine capable of controlling letter depth.

[0006] The rolling letter machine capable of controlling letter depth provided by the present application adopts the following technical scheme:

[0031] Preferably, an elastic member for applying an upward pushing force to the bearing frame is arranged between the lower side of the positioning leaning frame and the lower side of the bearing frame.

[0032] By adopting the technical scheme, the elastic member provides upward thrust to the bearing frame. In actual application, after the pipeline is placed in the erecting groove, the pipeline can be pushed to move close to the positioning taper head, and the positioning taper head is embedded into the pipeline.
