Abstract

The utility model relates to a suspension servo cylinder direct depressing variable cross-section rolling mill. The middle part of the rear side of the housing window of the mill is provided with a pair of cantilever type rear vertical roll mechanisms; the intermediate position of the upper part of the housing window is hung with an electro-hydraulic servo cylinder; the end of a cylinder lever is connected with a lifting board; both ends of the lifting board is coupled with two roller bearing seats; the actions of the servo cylinder is controlled to automatically depress for rolling variable cross-section rolling pieces; the utility model has the advantages of high rigidity of the entirety of the rolling mill and high rolling precision; on the other hand, the depression adjusting mechanism and the upper balancing mechanism on the common rolling mill are omitted, and the structure is obviously simplified.

Description

Hang servoBcylinder and directly depress the variable cross-section milling train

The utility model relates to a kind of variable cross-section rolling equipment, especially directly depresses the milling train of rolling changeable section rolled piece by the suspension type servoBcylinder.

At present, the variable cross-section milling train form of existing and known production automobile changeable section plate spring has: forging roll formula or promote a drift by hydraulic servo cylinder and press formula indirectly, and promote bottom roll bearing block by hydraulic cylinder and directly press several types such as formula and vertical miller.The thickness oblique cone distortion of variable cross-section rolled piece is by the cam-shaped roller or the voussoir or rolling by the plain-barreled roll variation roll gap realization of hydraulic servo milling train of forging roll, and the width deformation processing of rolled piece is then finished by edger roll mechanism after being contained in milling train.Usually edger roll mechanism after in the middle part of variable cross-section mill housing rear side, a pair of cantilevered being housed, comprise the back edger roll supporting arm that is installed on the mill housing and be contained in back edger roll, float plate, push rod, spring box, adjusting bolt, guide pillar on the edger roll supporting arm of back and combine and be fixed on the memorial archway, connecting rod, swing lock shaft and axle bed interconnect, and are fixed on the mill housing by axle bed or supporting plate.From existing variable cross-section milling train situation, forging roll is not suitable for rolling long awl rolled piece, and variety renovation inconvenience, and the roller consumption is big; Complicated on device structure by the Britain Hille variable cross-section milling train that hydraulic servo cylinder promotion drift presses indirectly, servoBcylinder requires flow big, and stroke is long; The full edger roll variable cross-section milling equipment structure of Germany is huge, complicated; Also there are problems such as installation and maintenance inconvenience in the milling train that is directly pressed by servoBcylinder.

The purpose of this utility model is to overcome the deficiency of above-mentioned variable cross-section milling train, a kind of variable cross-section milling train that servoBcylinder is directly depressed of hanging is provided, servoBcylinder is hung on monoblock type stiff mill memorial archway top,, realized the variable cross-section operation of rolling control of directly depressing by the action of control servoBcylinder.This structure has not only improved mill stiffness, and device structure is simple, has saved to depress guiding mechanism and last balanced controls, equipment processing, use and easy to maintenance on other milling trains.

The purpose of this utility model is achieved in that on by the variable cross-section milling train that comprises integrated rolling mill memorial archway, roll, back edger roll device, servoBcylinder and servoBcylinder flange are hung upper middle position at the integrated rolling mill memorial archway with hanger bolt, the servoBcylinder end can be connected by a pair of subdivision pressing plate along the lifter plate that mill housing window slides with one, and the lifter plate two ends are connected with two bearing blocks of topping roll by bolt respectively.By the action of electric control system controls servoBcylinder, just can realize the continuous lifting of topping roll, the automatic continually varying variable cross-section of the roll gap operation of rolling.

Below in conjunction with drawings and Examples the utility model is specified.

Fig. 1 is the utility model three-dimensional structure diagram.

In Fig. 1, servoBcylinder (1) and servoBcylinder flange (21) are hung upper middle position in integrated rolling mill memorial archway (2) with hanger bolt (20), the servoBcylinder end is connected with lifter plate (4) by subdivision plate (3), and lifter plate (4) two ends are connected with the bearing block (6) of topping roll (5) with bolt.Edger roll mechanism after a pair of cantilevered is equipped with at mill housing (2) rear side middle part, comprise and be installed in the back edger roll supporting arm (8) on the mill housing (2) and be contained in back edger roll (9) on back edger roll supporting arm (8), back edger roll oil cylinder (10) is fixed on the mill housing (2), float plate (11), push rod (12), spring box (14), regulate bolt (15), guide pillar (16) is combined and is fixed on the mill housing (2), and edger roll supporting arm (8) after the support, connecting rod (17), swing lock shaft (18) and axle bed (19) interconnect, and be fixed on the mill housing (2) by axle bed (19), wide with the control rolled piece to size, axially pressing plate (7) is installed on the mill housing (2) with bolt, regulate backing plate (13) pad below mill housing (2) window, to regulate lower roll roll surface height.

Control servoBcylinder (1) during work, servoBcylinder cylinder bar moves up and down, by the cylinder boom end drive lifter plate (4) of servoBcylinder (1) and the topping roll bearing block (6) that is connected with lifter plate (4), thereby making topping roll (5) do predefined roll gap changes, realize that continuous roll gap changes and the variable cross-section operation of rolling, rolls out desired changeable section plate spring curve.

Because the utility model hangs servoBcylinder on integrated rolling mill memorial archway top, the pressure of servoBcylinder is directly passed on the mill housing by the cylinder body flange when rolling, has reduced the elastic deformation amount of pressure part, milling train integral rigidity height, rolling accuracy height.That has saved common milling train on the other hand again depresses guiding mechanism and last balanced controls, and device structure is obviously simplified, processing, use and easy to maintenance.

Claims

1, a kind of servoBcylinder of hanging is directly depressed the variable cross-section milling train, edger roll mechanism after a pair of cantilevered is equipped with at integrated rolling mill memorial archway (2) rear side middle part, comprise and be installed in the back edger roll supporting arm (8) on the mill housing (2) and be contained in back edger roll (9) on back edger roll supporting arm (8), back edger roll oil cylinder (10) is fixed on the memorial archway (2), float plate (11), push rod (12), spring box (14), regulate bolt (15), guide pillar (16) is combined and is fixed on the memorial archway (2), connecting rod (17), swing lock shaft (18) and axle bed (19) interconnect, and be fixed on the mill housing (2) by axle bed (19), it is characterized in that: servoBcylinder (1) and servoBcylinder flange (21) are hung upper middle position in integrated rolling mill memorial archway (2) with hanger bolt (20), servoBcylinder (1) end is connected with lifter plate (4) by subdivision pressing plate (3), and lifter plate (4) two ends use bolt to be connected with two bearing blocks (6) of topping roll (5) respectively.
