Corrugated plate rolling machine

Abstract

The invention discloses a corrugated plate coiling machine, belonging to the field of coiling machines, which comprises a hydraulic pile, a rack, rolls and a roll stand, the rolls include an upper roll and a lower roll, there are two upper rolls, and the upper roll There are regular corrugations evenly arranged on the top, and the corrugations of the two upper rolls are the same; the lower rolls are also two, and the surface of the lower rolls is provided with corrugations corresponding to the corrugations on the surface of the upper rolls; The distance between the two lower rolls is smaller than the distance between the two lower rolls; the distance between the lower roll and the corresponding upper roll is controlled and adjusted by the hydraulic pile to drive the front and rear movement of the roll and the vertical up and down motion of the upper roll to process corrugated plates with different diameters When the coil is working, there is no need to replace the rolls. It has the advantages of standard arc shape, no straight line at both ends of the workpiece, high control precision, time-saving and labor-saving, and beautiful appearance of the product.

Description

technical field [0001] The invention belongs to the field of plate rolling machines, and more specifically relates to a corrugated plate rolling machine. Background technique [0002] With the growth of steel production and the continuous improvement of the level of science and technology, the types of steel products are also increasing. For example, the corrugated steel plate bridge and culvert structure, as an alternative product to make up for the defects of the commonly used concrete structure, is a new type of structure that increases the strength of the plate with a thickness of 4.0mm-8.0mm through corrugation and then assembles it. Corrugated steel plate is a typical space steel structure, which not only has the ability to adapt to foundation and foundation deformation, but also can solve the problem of bridge and culvert damage caused by uneven settlement of foundation foundation. Moreover, due to the existence of axial corrugations, the corrugated steel plate has e...

Problems solved by technology

[0006] Aiming at the processing of large-radius curling arcs in the prior art when the corrugated plate is coiled, it is realized by increasing the diameter of the roll, which wastes materials and high processing costs, and because the two ends of the product cannot be processed during product processing, the processed corrugated plate Both ends of the arc are still straight, and the resulting product is not a standard arc, that is, there is a problem of a straight line at both ends. The invention provides a corrugated plate rolling machine, which can adjust the radius of the coiled plate when processing the corrugated plate , and the resulting product is a standard arc, that is, there are no straight segments at both ends
