Abstract
The utility model relates to a vertical roller mechanism in front of variable cross-section rolling machine, which is used for a special rolling machine for rolling the variable cross-section leaf spring of a car. The rolling gap right ahead of the upper working roller and the lower working roller is provided with a front vertical roller mechanism; the front vertical roller mechanism comprises a front vertical roller, a supporting seat of a front vertical roller, a fulcrum bearing of a vertical roller, an apical axis, forcing off screws and a swinging support arm; the supporting seat of a front vertical roller is installed on a machine frame by the fulcrum bearing of a vertical roller. The utility model is controlled by computers; during the process of the production, the utility model is totally automatic; the utility model has the advantage of high accuracy of manufactured product sizes, etc. When the vertical roller mechanism in front of variable cross-section rolling machine is used, the front vertical roller is used for guiding, and therefore, that the centerline of a rolled piece is perpendicular to the centerline of a working roller can be ensured, and the rolled piece can not be bended laterally owing to the slant of material feeding.
Description
The utility model belongs to the parts in the plant equipment of leaf springs of car processing, is the parts that are used to produce on the special rolling mill of automobile changeable section plate spring, is edger roll mechanism before a kind of variable cross-section milling train.
In the past, to adopt traditional uiform section leaf spring for many years be the tower spring to leaf springs of car always.In recent years it is changeable section plate spring that the flourishing country of industry has developed a kind of novel leaf spring, and this changeable section plate spring is by the design of beam of uniform strength principle, and the attenuation gradually of thick middle two ends only just can replace 5 to 8 traditional uiform section leaf springs with 1 to 3.This leaf spring is owing to save raw metal and have advantages such as fatigue life is long and generally promoting, the changeable section plate spring that China produces now mostly adopts the forging roll moulding, this technology and equipment are all very backward, its major defect is: manual operations, single-piece production, labour intensity is big, production efficiency is low, the product size precision is difficult to guarantee, and Mould Machining (promptly forging roller) difficulty, wearing and tearing back are difficult for repairing, cost is high.
The existing milling train of producing leaf springs of car has many kinds, and the leaf spring of being produced has uiform section leaf spring and changeable section plate spring.This original uiform section leaf spring is used for that material used on the vehicle is more, cost is higher and has increased the deadweight of vehicle widely; The leaf spring of existing vehicles is mostly substituted by changeable section plate spring, the plant equipment of producing this changeable section plate spring also has many semi-automatic processing machine tool equipment except that original production technology machinery: accept and disclosed application number is 9220014.0, denomination of invention is the utility model patent of rolling double joint board of variable section spring arrangement as Patent Office of the People's Republic of China, it is mainly levied and be to be equipped with a pair of middle edger roll between two edger roll, middle edger roll fixed mount is connected with crossbeam, base, dividing plate is housed sending between the pressing plate that draws materials device.This mode mainly is simultaneously can rolling two changeable section plate springs, but its main processing equipment part and existing equipment class are seemingly, because edger roll mechanism thereby product processed quality are not lower before being provided with, product subscription rate rate is higher.In addition, many in recent years producers have introduced the variable cross-section milling train of Britain HILLE company, though this milling train has overcome the existing defective of forging roll, also have following several problems:
1, adopt the complicated upper and lower material of Pneumatic manipulator of a cover, establish source of the gas separately, the complex structure of manipulator itself, cost height, and slow in one's movements, prolonged the non-cutting time of production, thereby production efficiency is low;
2, this milling train does not have preceding edger roll, and last width is uncontrollable, and the rolled piece width dimensions can not guarantee, does not lead during the jaw feeding, send askew rolled piece easily, causes defectives such as lateral bending.
Goal of the invention of the present utility model provides edger roll mechanism before a kind of being provided with at above-mentioned situation, be used to produce edger roll mechanism before the variable cross-section milling train on the variable cross-section milling train of automobile changeable section plate spring.
Edger roll mechanism realizes in the following manner before the variable cross-section milling train of the present utility model:
Edger roll mechanism before the variable cross-section milling train of the present utility model is to be used on the special rolling mill of rolling automobile changeable section plate spring.Edger roll mechanism before the dead ahead of upper and lower working roll work roll gap place is equipped with.Preceding edger roll mechanism includes preceding edger roll, preceding edger roll bearing, preceding edger roll supporting base, apical axis, jackscrew, swinging mounting arm.Preceding edger roll bearing is installed on the frame by preceding edger roll supporting base, and the edger roll bearing was with the roll gap between the edger roll before controlling before apical axis withstood; Hang with a spring on preceding edger roll bearing, the other end of spring is fixed on the frame by the lifting bolt on the frame; Spring and apical axis apply both direction opposite effect power to preceding edger roll bearing, and the edger roll bearing is stable before making, and be certain with the roll gap between the edger roll before guaranteeing.
Edger roll mechanism has following advantage before the variable cross-section milling train of the present utility model:
1, controls all automations in the production process with computer;
2, the product size accuracy of Sheng Chaning is higher;
3, Mould Machining and change convenient, of the present utility model before edger roll, adopt indefinite chill spheroidal graphite cast-iron to make, processing and fabricating is convenient, low, the long service life of cost, when roller coarse and when influence product quality, can be with turning or the repeated use of polishing back;
4, this milling train has preceding edger roll, play the guiding role when feeding, can guarantee that rolled piece is vertical with the working roll center line, can not make rolled piece produce lateral bending because of feeding is crooked.
Followingly in conjunction with the accompanying drawings the frame for movement and the technology contents thereof of edger roll mechanism before the variable cross-section milling train of the present utility model is further described:
Fig. 1 is that preceding edger roll mechanism of the present utility model is installed in the structural representation on the variable cross-section milling train;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is an assembly structure figure of the present utility model;
Fig. 4 is the A-A cutaway view of Fig. 3;
