Embodiment Construction

[0038] The present invention will be described in detail below with reference to the accompanying drawings and examples. Any equivalent change and modification of the contents of this specification shall belong to the scope of the present invention to provide protection.

[0039] See figure 1 , figure 1 A scribing method for use in the steel pipe elbow line for the marine low speed diesel engine, which can be used for a diameter of diameter. Steel tube bending; the scribe device includes two positioning seat assemblies and a planned line.

[0040] The positioning seat assembly can move, including a base pad 1, a restricted plate 2, a T-block 3, and a fastening bolt 6.

[0041] See figure 2 The lower portion of the base pad 1 is provided with a V-tank 11 for placing the steel pipe, the opening of the V-tank 11, and the two faces of the two faces are 120 °, and the position is respectively configured. The inner side wall surface 14 of the base pad 1 is provided in a T-slot 12 in th...

Abstract

A marking device and method for steel pipe bending, including two positioning seat assemblies and a marking ruler; wherein, the positioning seat assembly includes a base pad, a limit plate, a T-shaped block and fastening bolts, and the base pad The block is provided with a V-shaped groove for placing steel pipes and a T-shaped groove along the vertical direction. The limit plate is connected with the T-shaped block and installed in the T-shaped groove, and can move up and down along the T-shaped groove. The marking ruler includes fastening Nut, left ruler and right ruler, the left end of the right ruler is connected with the right end of the left ruler. There is a length scale for measuring the marking distance; during the marking operation, place the steel pipe elbow horizontally in the V-shaped groove of the two base blocks, and make the limit plate move along the T-shaped groove until it touches the steel pipe elbow And fix the limit plate, close the marking ruler to the limit plate, tighten the fastening nut, read the scale on the marking ruler, and mark the blanking size by marking. The invention has the advantages of simple structure, convenient use, high reliability, wide application range and the like.

Description

Technical field [0001] The present invention relates to the manufacture of a marine low-speed diesel engine, and more particularly to a scribe device and method for a steel pipe bend, which belongs to the field of diesel engine manufacturing. Background technique [0002] In the production of marine low-speed diesel traces, many tubes of each pipe system need to carry out eliminating tubes, such as oil-proof system tubing, cooling water system tubing, fuel system tubing, air system tube system. During the bending of various steel pipes, since the time needed bender clamp pipe bending mold clamping, and mold clamping shortest length is limited, so when some of the length of the tubes is shorter than the length of the mold clamping, prior to bending The blank needs to leave a length of length. After the steel pipe is bent, the excess length is cut and removed according to the design size. [0003] Current methods for the marine diesel engine bending steel material scribing is taken...
