Three-memorial-archway variable-specification quick roll changing rolling mill

Abstract

In the technical field of high-frequency welded pipe production lines at present, square and rectangular pipes are generally required to be produced by one machine with multiple functions, the square and rectangular pipes of multiple specifications and special-shaped pipes of other shapes can be produced, and in order to meet the market requirements, the embodiment of the invention provides a three-memorial-archway variable-specification quick roll changing rolling mill capable of producing the square and rectangular pipes of multiple specifications and meanwhile achieving quick roll changing to produce the special-shaped pipes of other shapes. A floating memorial archway is additionally arranged on the basis that an original rolling mill is only provided with a fixed memorial archway and a movable memorial archway, and quick roll changing is achieved by detaching the movable memorial archway. The specifications can be changed by changing the distance between the floating memorial archway and the movable memorial archway.

Description

Technical field [0001] The present invention relates to a multi-gauge rolling BACKGROUND automated production line type continuous flexible sheet material, particularly to a variable size to three arch quick roll mill. Background technique [0002] In today's high-frequency welded pipe production line art, for the production of Rectangular Pipe machine usually requires a multi-energy side, i.e., the production line can produce a variety of product specifications of the rectangular tube, so in order to meet the needs of the market, pipe production line the manufacturer usually designed to quickly change the rolling host production specifications simple conversion operation can be achieved by the machine, common way is to roll the rolling pitch is achieved by varying the width of the square pipe height changes, but because the market the diverse needs of existing rolling technology has been unable to meet demand, customers need to expand the range of processing production line can ...

Problems solved by technology

[0002] In today's high-frequency welded pipe production line technology field, the production of square and rectangular pipes usually requires one machine with multiple functions, that is, a set of production lines can produce square and rectangular pipe products of various specifications. Therefore, in order to meet the needs of the market, welded pipe production lines Manufacturers usually design the main rolling machine so that the whole machine can quickly change the production specifications through simple conversion actions. The common way is to change the width, narrowness, and height of the square tube by changing the pitch of the rolling rolls. However, due to the market The existing rolling technology can no longer meet the needs of the diversified needs. The customer needs to expand the processing range of the production line, not only to be able to produce multi-standard square and rectangular tubes, but also to be able to produce other shapes of special-shaped tubes. In order to meet the needs of the market Therefore, those skilled in the art will increase the ability of quick roll change on the basis of the existing rolling technology, then develop a set of equipment that can not only realize the production of multi-standard square tubes, but also quickly change rolls to produce other shapes. The three-paifang variable-specification quick-roll change mill for special-shaped pipes has become an inevitable trend
