Abstract
The invention discloses a combined roller. The combined roller comprises a left support, a right support and a wear-resistant part arranged between the left support and the right support. The left support and the right support are prepared from a copper alloy. The wear-resistant part is prepared from alloy tool steel, has high hardness and large strength, reduces upper roller scratches and wearing produced by welding lines, can improve service lives of tools and molds, a yield of a welded pipe production line, and production efficiency, and can reduce large amounts of costs of tools and molds.
Description
?
Technical field
The invention belongs to the welded tube process units, be specifically related to a kind of combination roller.
Background technology
Present welded pipe product line is to be made up according to production technology by many single device, is arranged into the streamline form.It mainly is by shaping machine set, welder, sizing unit, annealing furnace, straightener, flies the sawing off line and forms.The emphasis of moulding is at moulding process, and it is made up of tens pairs of format rolls, and welded tube production mainly is to take cold rolling principle, is rolled into the cylindric vertical masonry joint welding of carrying out to band, obtains the ERW of required diameter.When rolling entering precisive shaped,, the parallel rollers top roll is scratched serious because the strip edge part is sharper.
Because what titanium welding pipe production line format roll adopted is copper alloy; Hardness 36-42HRC is lower many than Cr12MoV (original mould Material Used) 58HRC; The pipe weld that welding is good has certain reinforcement; The relative mother metal of weld hardness is harder, so the pipe after the welding well has certain injury to back size rolls and smoothing roll top roll pass surface.
Summary of the invention
Goal of the invention: the objective of the invention is to deficiency, provide a kind of simple in structure, reduce wear, the combination roller of convenient replacement to prior art.
Technical scheme: the invention discloses a kind of combination roller, comprise left socle, right support, be arranged on the wearing piece between left socle and the right support.
Said left socle and right support are copper alloy.
Said wearing piece is an alloy tool steel; Hardness improves, and intensity increases, and has reduced scuffing and the wearing and tearing of weld seam to top roll; Can improve tool and mould service life, improve welded pipe product line lumber recovery, enhance productivity, can save a large amount of tool and mould costs for enterprise.
Beneficial effect: combination roller disclosed by the invention; Simple in structure, easy for installation, hardness improves; Intensity increases; Reduced scuffing and the wearing and tearing of weld seam to top roll, can improve tool and mould service life, improve welded pipe product line lumber recovery, enhance productivity, can save a large amount of tool and mould costs for enterprise.
Description of drawings
Accompanying drawing is the structural representation of combination roller.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
The invention discloses a kind of combination roller, comprise left socle 1, right support 2, be arranged on the wearing piece 3 between left socle 1 and the right support 2.
Said left socle 1 is a copper alloy with right support 2.
Said wearing piece 3 is an alloy tool steel; Hardness improves, and intensity increases, and has reduced scuffing and the wearing and tearing of weld seam to top roll; Can improve tool and mould service life, improve welded pipe product line lumber recovery, enhance productivity, can save a large amount of tool and mould costs for enterprise.
The invention provides a kind of thinking and method that makes up roller, realize that specifically the method for this technical scheme and approach are a lot, the above only is a preferred implementation of the present invention; Should be understood that; For those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching; These improvement and retouching also should be regarded as protection scope of the present invention, and all available prior art of each part not clear and definite in the present embodiment realizes.
Claims (3)
