Square tube roller device and square tube squaring machine applying same

Abstract

The invention discloses a square tube roller device and a square tube squaring machine applying the same, and relates to steel tube machining equipment. The square tube roller device comprises a mounting base, four rollers and four roller shafts rotationally erected on the mounting base, wherein the rollers are evenly distributed in the circumferential direction, any roller shaft is arranged in the direction of the connecting line of the corresponding roller and the circle center of the circumference in a sliding mode, and an adjusting assembly used for driving the roller shafts to move synchronously is further arranged on the mounting base; and a square tube squaring machine comprises a machine table and a plurality of square tube roller devices, wherein the square tube roller devices areevenly arranged at intervals in the length direction of the machine table, and the square tube roller device is movably and adjustably arranged in the width direction of the machine table. The squaretube roller device and the square tube squaring machine applying the same are stable in work, convenient and fast to operate, capable of conveniently producing square tubes of various sizes and specifications and beneficial to improving the production efficiency and the square tube forming quality.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing equipment, in particular to a square tube rolling device and a square tube squaring machine using the device. Background technique [0002] Square pipe is a name for square pipe; as an economical and efficient steel, it is mainly used in engineering and construction fields, including steel structure houses, main workshops, boiler steel frames, municipal construction, and machinery manufacturing. At present, the production processes of square tubes mainly include welding, cold pushing, cold drawing or cold rolling; cold pushing, cold drawing or cold rolling square tubes are made of hot rolled or welded capillary tubes, which are drawn or drawn after pickling to remove scale. Square tubes produced by rolling and cold deformation. [0003] Existing publication number is that the invention patent application of CN103316916A discloses a kind of square tube setting machine and the product...

Problems solved by technology

But in the prior art, after each roller is installed, it cannot be adjusted or it is inconvenient to adjust; if it cannot be adjusted, the size of the square hole surrounded by each roller is relatively fixed, and it is difficult to meet the processing operations of square pipes of various sizes; if it is inconvenient to adjust, For example, it is necessary to manually adjust one by one, and it is also necessary to consider whether each roll can form a standard square hole after adjustment, which is time-consuming and laborious, and the operation efficiency is extremely low. Once the operation is not good, it will easily affect the quality of the square tube forming.
