Abstract

The utility model belongs to cold mill equipment and particularly relates to a small roll-diameter four-roll reversing cold mill with electric supporting rolls, which is suitable for rolling special stainless steel and various alloy steel pieces at normal temperature. The small roll-diameter four-roll reversing cold mill with the electric supporting rolls is characterized in that a main motor on the drive side of the mill is an overload main motor; an output shaft of the main motor is connected with an input shaft of a composite speed reducer by a coupler; the upper output end of the composite speed reducer is connected with an upper supporting roll by a connecting shaft; the lower output end of the composite speed reducer is connected with a lower supporting roll by a transmission shaft; and an upper working roll driven by the upper supporting roll and a lower working roll driven by the lower supporting roll are sequentially arranged between the upper supporting roll and the lower supporting roll, so that the rolling work of the small roll-diameter four-roll reversing cold mill is implemented. The small roll-diameter four-roll reversing cold mill not only has a reasonable design and a compact structure, is suitable for a process of a cold mill unit and is simple to control, but also has the advantages of high strength, reliable working performance, higher production efficiency, great convenience in operation and use, and the like.

Description

The pony roll footpath four roller reversable cold-rolling machines of electronic backing roll

Technical field

The utility model belongs to cold-rolling mill equipment, particularly is applicable to the pony roll footpath four roller reversable cold-rolling machines of a kind of electronic backing roll of rolling at normal temperatures special stainless steel and various alloy steel pieces.

Background technology

At present; When rolling at normal temperatures special stainless steel and various alloy steel piece, adopt four roller reversable cold-rolling machines of motor-driven working roll usually, its structure comprises common main motor, shaft coupling, compound reductor, power transmission shaft, chuck, power transmission shaft carriage, backing roll and working roll; The thin and narrow characteristic of size wall according to special stainless steel rolled parts and various alloy steel rolling parts; Usually it is rolling to adopt the working roll in motor-driven pony roll footpath, but since its special stainless steel material and various alloy steel products not only hardness height but also intensity were big, when therefore rolling; Both the roller footpath was little for this pony roll footpath working roll; Export big roll torque again, cause its pony roll footpath working roll that damaged fracture takes place easily, and influence ordinary production.

Summary of the invention

The utility model is intended to the shortcoming and defect part that in said method, exists; And providing not only reasonable in design, compact conformation had both adapted to the technology of cold rolling unit; Control is simple again; And having the intensity height, reliable working performance is enhanced productivity and is manipulated the pony roll footpath four roller reversable cold-rolling machines of a kind of electronic backing roll very easily.

The purpose of the utility model is to adopt following technical scheme to realize: the pony roll footpath four roller reversable cold-rolling machines of described electronic backing roll; Comprise that main motor, compound reductor, power transmission shaft, chuck, power transmission shaft carriage, top backing up roll, lower support roller and upper and lower working roll is characterized in that: the main motor of its milling train transmission side adopts the main motor of overload type; The output shaft of its main motor is connected with the power shaft of compound reductor through shaft coupling; The last output of described compound reductor is connected with top backing up roll through power transmission shaft; The following output of its compound reductor is connected with the lower support roller through power transmission shaft; Install top working roll that drives by top backing up roll and the bottom working roll that moves by the lower support roller strap above that between backing roll and the lower support roller in regular turn, realize the rolling work of pony roll footpath four roller reversable cold-rolling machines.

The principle of the utility model is set forth in down with the operation branch:

The utility model is at the main motor of milling train transmission side installing overload type; When rolling; Two main motors rotate simultaneously; Drive upper and lower backing roll respectively through shaft coupling, compound reductor and power transmission shaft and rotate, the frictional force between its upper and lower backing roll and the upper and lower working roll makes upper and lower working roll rotate, thereby obtains roll torque; Every connects a two ends and adorns a telescopic power transmission shaft; One of them telescopic power transmission shaft links to each other with the output of compound reductor; Another telescopic power transmission shaft is connected with supporting roller; Power transmission shaft is clamped by chuck on when roll change, and lower drive shaft is connect shaft tray and holds, and satisfies the requirement of fast roll changing.

The comprehensive above technical scheme of being taked realizes the purpose of the utility model.

Compared with present technology, the utility model is not only reasonable in design, and compact conformation had both adapted to the technology of cold rolling unit, and control is simple again, and has the intensity height, and reliable working performance is enhanced productivity and manipulated advantages such as very convenient.
