Description

Combined type cold-forming shapes roll

Technical field

The utility model be the roll that uses on the cold-forming shapes milling train, particularly clod wash rolling be the roll of the section bar of raw material with the stainless steel band.

Background technology

Here said cold-forming shapes milling train serves as typical case's representative with rolling stainless steel door window profile, and it is raw material with the stainless steel band, and a large amount of efficient rolling bar section of stainless steel of cold roll forming are used to assemble Door or window made of stainless steel.Door or window made of stainless steel is because of having advantages such as intensity height, corrosion-resistant Never-rusty, long service life, outward appearance are luxurious, obtains application more and more widely over surplus in the of nearly ten year on building and decorative engineering.The cold-forming shapes milling train of rolling stainless steel door window profile generally needs the 20-30 breaker roll.

The roll that uses on the prior art cold-forming shapes milling train, normally solid all-in-one-piece, body of roll entire body adopts steel alloy, materials such as Cr12,40Cr, 38CrMoA1A, high alloy tool steel for example, make through forging, machining, heat treatment, correct grinding, the high material consumption waste is big, and processing capacity is big, the manufacturing cost height.And because roll weight is big, the required transmission device power of milling train is big, and energy resource consumption is also big during operation.Moreover this monoblock type roll, costs dearly causing scrapping of whole roll because of using wearing and tearing or causing part (as cutting edge) to damage accidentally.

Summary of the invention

The utility model purpose provides a kind of combined type cold-forming shapes roll, and it is divided into several sections with the body of roll of roll by the characteristic of operational forces, with different material manufacturings, has only the segment section steel alloy, and the body of roll is the combining structure of hollow.

The utility model combined type cold-forming shapes roll comprises the body of roll, power transmission shaft, securing member, is key connecting between the body of roll and power transmission shaft, with securing member the body of roll and power transmission shaft assembling is connected into one.The body of roll is that half hollow structure is made up in segmentation, promptly is divided into the pressure section, embraces and protect power section and the power of tracking section by operational forces character.Wherein the pressure section adopts the steel alloy manufacturing, follows the tracks of the power district and embraces and protect the power section and then adopt high-strength cast iron.The interlude of the body of roll is roughly the plate-like of band central shaft hole and keyway, and body of roll two ends are roughly the bowl-shape of band central shaft hole, thereby the inside at body of roll interlude and two ends forms cavity.Cooperate the location with circular hole and annulus platform between adjacent two sections of the body of roll.

The combination body of roll two ends with double nut with the body of roll and power transmission shaft fixing and locking.Red steel card pad is arranged between body of roll both ends of the surface and the nut.Body of roll both ends of the surface can have boss, and the groove of dress pad is arranged on the boss.

The utility model design is based on following technical Analysis and design.Roll on the cold-forming shapes milling train is a mounted in pairs, promptly is divided into topping roll and bottom roll.Workpiece (as stainless steel band) is rolled moulding between topping roll and bottom roll, the body of roll of roll is its active section.Press the character of active force on the body of roll, its active force can be divided into pressure, embrace three kinds of power, the tracking power of protecting.The dynamics of three kinds of power has a long way to go, and pressure is to embrace to protect more than 30 times of power approximately, and embracing the power of protecting is more than 10 times of tracking power approximately.In view of the above, the body of roll of roll can be divided into different active force sections, different active force sections is combined into integral body then with different material manufacturings, not only satisfies specification requirement, and its technical and economic performance is improved greatly.

The body of roll of roll all is widely different turning.In general, the surface of the pressure section of the body of roll is the acute angle or the right angle of projection, or the shapes such as the portion that exerts pressure of groove, initiatively exerts pressure during work, and dynamics is also maximum, so adopt the steel alloy manufacturing.Embracing the surface protect the power section is the obtuse angle, and recessed groove cooperates with the pressure section during work and bears pressure, finishes the workpiece partial plastic forming, and dynamics is medium, and generally steel alloy is then used in cylinder iron manufacturing during great efforts.Tracking power section surface is plane or mild curved surface, and the surface has only the frictional force of roll extrusion during work, and the dynamics minimum is cylinder iron made.But, the section division of power on the body of roll, finally depend on variation workpiece shape and to the analysis of power, and to the identification of the size (dynamics) of power.

The body of roll and power transmission shaft have key connecting, so its interlude is the plate-like of band central shaft hole and keyway.Because the section that the body of roll has has adopted cast iron, so be easy to adopt casting technique and hollow structure, roll weight is alleviated greatly.

The utility model combined type cold-forming shapes roll roll compared to prior art has following outstanding feature:

(1) the steel alloy consumption is few.The body of roll has only the pressure section to adopt steel alloy, so close

Gold steel consumption reduces to 1/3 to 1/4 of solid roll approximately, and all the other are high-strength cast iron,

Material cost reduces greatly.

(2) in light weight, energy resource consumption is little.The design's roll barrel is the casting of half hollow

Process structure, roll weight saving approximately has only 2/3 of prior art roll weight.With

also reduced milling train transmission device power output, energy resource consumption and operating cost.

(3) processing technology is good, and processing capacity reduces.Use the steel alloy section few, reduced

Processing capacity.Owing to make section cylinder iron adopt casting, machining amount also reduces again.

(4) abrasion resistance properties is good.Cast iron section on the body of roll has good wearability

Can, prolonged service life.

(5) be easy to change.This is the benefit that the combined section structure is brought.Particularly ought make

When damage being arranged, only need to change the section that damages, avoided scrapping whole with the section of steel alloy

The big loss that roll causes.
