Description

A kind of new roller structure for being used to manufacture changeable section plate spring

Technical field

The utility model is related to roll structure technical field, especially a kind of new roller for being used to manufacture changeable section plate spring Structure, roll structure lightweight, operating efficiency is high and is easy to maintenance.

Background technology

Leaf spring is the important component of automobile suspension system, plays one between transmission and buffering vehicle frame and wheel The effect of shear force and torque.The leaf spring reed used at present has uiform section structure and variable section structure.Uiform section structure is Be in close contact between a kind of traditional trapezium structure form, reed, pressure is big, friction is serious, heating height, fatiguability, fracture and Waste of materials；Changeable section plate spring is hardly contacted between a kind of new leaf spring, reed, with rub it is small, antifatigue, The advantages of long lifespan, saving material, the stationarity of the improvement running car of energy conspicuousness, is a kind of vapour by broad prospect of application Car component assembly.Changeable section plate spring is the light-weighted Main Trends of The Development of leaf spring, and short cone milling train is manufacture changeable section plate spring One of capital equipment.Roll is the strength member on rolling mill, the pressure produced when being rolled using a pair or one group of roll come Stone roller steel are rolled, are to make（Stocking）Metal produces the instrument of plastic deformation, is the important consumption for determining rolling mill efficiency and mill bar quality Part.

Most of existing roll uses the roll of monolithic construction, and original design roll uses unlimited chilled ductile iron, It is a kind of alloy ductile iron containing Cr, Ni, Mo, material price is expensive and roll is integrally heavier, is not easy to maintenance and changes, and roll Wear and tear very serious in use, once reaching the limit of wear, roll can only integrally be scrapped, cause a large amount of waves of resource Take, also increase the acquisition cost of roll.

Therefore, a kind of lightweight, portable, the roll structure that operating efficiency is high, cost is low are the purpose of this utility model Place.

The content of the invention

To overcome the deficiencies in the prior art, the utility model combination actual conditions are optimized to short cone milling train topping roll and set There is provided a kind of new roller structure for being used to manufacture changeable section plate spring for meter.

The utility model solves the technical scheme that its technical problem used：It is a kind of to be used to manufacture the new of changeable section plate spring Type roll structure, including horizontal roll roll body and co-axial roll mandrel, the roll mandrel include roll mandrel I, roll mandrel II and roll mandrel III, roll roll body is provided with the middle of the roll mandrel III, and the roll roll body includes being fixed on roll mandrel III Roll mandrel I, the roll mandrel II for being fixed on the right side of roll mandrel I, dismountable roll alloy sheath and fixation are enclosed on roll mandrel II Two round nuts, the roll mandrel II, roll alloy are rotary with successively in retainer ring on the right side of roll mandrel II, the retainer ring Put and be respectively equipped with identical keyway, the keyway mouthful of the keyway is completely superposed, and is constituted and is put in a square groove, the square groove It is equipped with square key identical therewith.

Further, the material of the roll mandrel is 5CrNiMo materials.

Further, the roll alloy sheath is high nickel alloy material.

Further, the diameter of the roll mandrel I is between the inside and outside diameter of roll alloy sheath, the roll The interior diameter of alloy sheath is slightly larger than the diameter of the roll mandrel II.

Further, the round nut inner surface is provided with screw thread, outer surface is provided with groove at equal intervals.

Further, overall diameter and roll mandrel II of the size of the round nut overall diameter between the roll alloy sheath Diameter between.

The beneficial effects of the utility model are：1）Convenience easy to maintenance：The utility model becomes original monoblock type roll to divide Body formula roll, improves roll maintenance, replacing, processing etc. when abrasion and brings great inconvenience；2）Wearability is good, uses the longevity Life length：Roll alloy sheath forges post-processing shaping using high nickel alloy material, improves the service life of roll structure, subtracts simultaneously The light weight of roll structure；3）Save material：Roll mandrel is forged using 5CrNiMo materials and formed；4）Reduction, which is purchased, repairs into This：Split type roll wear only needs to change roll alloy sheath after scrapping, and solves roll structure whole once it may wear to the limit Body is scrapped, and significantly reduces roll buying and use and maintenance cost；5）Structure is novel simple, and simple to operate, product appearance is good, Satisfactory changeable section plate spring product can effectively and rapidly be rolled out.
