Description

A kind of roll-type cold-rolling mill

Technical field

The utility model belongs to machining equipment, particularly a kind of roll-type cold-rolling mill.

Background technology

Develop rapidly along with science and technology, the production unit of electronic devices and components is used some little and thin sheet metal strips always, the flatness of these materials, surface smoothness, dimensional accuracy all has very high requirement, and its required material is little in batches, wide in variety, be difficult to buy suitable dimensions on the market, the close specification products of purchase that adopt carry out once more rolling more, because existing cold-rolling mill equipment is huge, roll-force is also very big, be not suitable for once more rolling needs, the band after rolling has a strong impact on the fineness of product, flatness has been brought great restriction to manufacturing enterprise.

Summary of the invention

The purpose of this utility model provides a kind of rolling requirement that can satisfy the non-ferrous metal of all kinds of thin slices, and is simple in structure, the roll-type cold-rolling mill that rigidity is high.

For achieving the above object, solution of the present utility model is: a kind of roll-type cold-rolling mill, comprise frame, on, bottom working roll and last, the lower support roller, frame is made up of fore side support body and transmission side support body, on described, bottom working roll and last, the lower support roller is arranged on the frame, the upper support roller, top working roll, bottom working roll and lower support roller from top to bottom join by roll surface successively, depth of parallelism axial adjustment track is installed in the left and right sides of support body hollow bulb, in the depth of parallelism axial adjustment track of the left and right sides, be separately installed with on two traversing and two traversing down, the diameter of described backing roll and working roll satisfies 3-5: 1, the length and the diameter of described backing roll satisfy 1-2: 1, and the length and the diameter of described working roll satisfy 3-6: 1.

Described in the utility model traversing by bolting on track, described track be near working roll one end narrow, away from the wide wedge-shaped slot of working roll one end.

The utility model all is better than the cold-rolling mill of existing same use at aspects such as rigidity and stressed and rolling thickness levels.The horizontal and vertical intensity of the utility model is respectively 1.2 times and 1.6 times of prior art; The utility model can reach 300 tons of pressure; The rolling product thickness of the utility model is equivalent to the 1/1000-1/1600 of work roll diameter, four-roll five-machine frame, the seven frame tandem rolling cold-rolling mills of surpassing far away, rolled products thickness can reach 0.06mm, and the limit can reach 0.04mm, and its thickness far is thinner than the 0.2mm that prior art reaches.

The utility model is simple in structure compared with prior art, stressed rationally, rigidity is high, precision good, template is easy to control, can produce high-quality product, can single chassis production, also can produce by the two-shipper frame, can be suitable for designing new machine frame rolling mill, also can be suitable for the prestressed stand milling train, can also be applicable to old five frames, seven machine frame rolling mills are transformed, work roll diameter is little, reduced draught pressure, the energy-conservation condition that provides has been provided, be convenient to make, be convenient to operation, help safeguarding and adjusting.
