Abstract
The utility model provides a pipe orifice diameter size control fixture, which comprises locating rings arranged on two sides of a welding edge of a plate to be circularly rolled, wherein rolling diameter control is realized by the locating rings which are symmetrical with respect to the welding edge through a chain block. According to the utility model, the whole direct spot welding of the prior art is abandoned, the spot welding specific to a middle section is carried out in sequence first, and the locating rings and the chain block are arranged at two ends in a cooperation manner to achieve accurate control of the plate rolling diameter, and the error rate produced by the diameter is greatly decreased; and the pipe orifice diameter size control fixture meets national standards, and contributes to improvement of whole engineering quality and structural behavior.
Description
Technical field
The utility model relates to the Construction of Steel Structure technical field, is specifically related to a kind of nozzle diameter size control frock.
Background technology
In the construction of steel construction, groove and volume bowlder are made in blanking, as not adopting external device control nozzle diameter; Can make diameter produce error; Rub the limit with the hands and surpass engineering and national standard allowable error scope, have a strong impact on construction quality and structural behaviour, leave over potential safety hazard to engineering.
The utility model content
To the problem that exists in the above prior art, the utility model provides nozzle diameter size control frock a kind of simple in structure, convenient and practical.
The utility model is realized through following technical scheme:
Nozzle diameter size control frock, said control frock comprise and are arranged at the locating ring of waiting to roll up plectane material welded edge both sides that said locating ring with respect to the welded edge symmetry is realized the control of volume circular diameter through chain block.
Said locating ring is arranged at waits to roll up plectane material welded edge two ends.
Said wait to roll up plectane material stage casing through the location welding fabrication.
The beneficial effect of the utility model is: abandon whole direct spot welding of the prior art; But to stage casing elder generation spot welding; Combine to adopt locating ring and chain block to realize the accurate control of sheet material volume circular diameter to two ends again; Greatly reduced the error rate that diameter produces, National standard is beneficial to and improves integrated engineering quality and structural behaviour.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 for waiting to roll up the girth sheets material; 2 is locating ring; 3 is chain block.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details.
The utility model provides a kind of nozzle diameter size control frock, comprises being arranged at the locating ring 2 of waiting to roll up plectane material 1 welded edge both sides, with respect to realizing the control of volume circular diameter through chain block 3 between the locating ring 2 of welded edge symmetry.Specifically, the volume circle, is arranged at and waits to roll up plectane material 1 welded edge two ends so locating ring 2 always has 4 to whole sheet material, waits to roll up plectane material stage casing then through the multipoint positioning welding fabrication.
The utility model is abandoned whole direct spot welding of the prior art; But to stage casing elder generation spot welding; Combine to adopt locating ring 2 and chain block 3 to realize the accurate control of sheet material volume circular diameter to two ends again; Greatly reduced the error rate that diameter produces, National standard is beneficial to and improves integrated engineering quality and structural behaviour.
