Description
Technical field
The utility model relates to lifting finger behind a kind of straightener, belongs to technical field of steel rolling.
Background technology
In rolling process, 13 meters-76 meters synchronous turning devices of rolled piece in the rolling machinery.Rolled piece is through often occurring lateral bending, product quality problem such as curved up and down behind the straightener.Design in the past all is to check in product region, but curved up and down the inspection too of rolled piece lags behind herein, can form between aligning operation and finished product operation and need the curved up and down defective work of aligning in batches.Aligning back workpiece measurement is long simultaneously, generally between 13 meters-76 meters, if turn over the flexural deformation that the bad meeting of steel device synchronism causes upset back rolled piece.Lifting finger is in the past adopted the synchronous or synchronous design of encoder speed of a power transmission shaft more, and such lifting finger investment is big, equipment is complicated, and workpiece measurement easily changes before and after the upset.Promptly belong to these row as the utility model that the patent No. is 02269895.7, name is called " tilting gear ".
Summary of the invention
Be defective and the deficiency that overcomes prior art, it is a kind of reasonable in design, simple in structure and turn over lifting finger behind the steel outstanding effect straightener that the utility model provides.
Lifting finger behind a kind of straightener is made up of six steel devices that turn over that are installed in behind the straightener, it is characterized in that each turns over the steel device and is made up of forearm, big arm, little arm hydraulic cylinder and big arm hydraulic cylinder, forearm and greatly arm one end be hinged by jackshaft; Have the turning on nearly jackshaft one end of forearm; the push rod of little arm hydraulic cylinder is hinged both by jointed shaft in forearm corner; little arm hydraulic cylinder is fixed on the big arm other end by jointed shaft, can drive forearm when the push rod of little arm hydraulic cylinder moves and rotate around jackshaft; The push rod of big arm hydraulic cylinder is hinged both by jointed shaft in the middle part of big arm, and big arm hydraulic cylinder is fixed on the outer basis of rollgang by holder, and the push rod of big arm hydraulic cylinder moves and can drive big arm and rotate around jackshaft; Jackshaft is contained on the middle framework of rollgang; Six big arm hydraulic cylinders and the action of forearm hydraulic cylinder synchronous can realize rolling up, turning down of rolled piece and turn over steel device self hidden function.
1. sequence of movement is dug preceding forearm hydraulic cylinder 4 and is stretched out, and forearm is 90 ° of states with big arm; Big arm hydraulic cylinder stretches out, and drives 90 ° of rolled piece upsets; Inspection finishes, big arm hydraulic cylinder withdrawal, rolled piece return-to-home position; The withdrawal of forearm hydraulic cylinder is 180 ° with big arm, is in hidden state.(its operating position and shape can be with reference to shown in the figure 3A.) in the very first time the curved up and down situation of product is checked that the rolled piece after will rectifying when needing to check turns over steel 90, dig check finish after, with turning over the steel device rolled piece is turned back, enter next step operation; Need not check when rolled piece is bent situation up and down, turn over the steel device and can hide, can not influence rhythm of production.
2. turn over 6 groups of steel devices and turn over the steel device and adopt " following " principle synchronously, because aligning back workpiece measurement is long, if turn over the flexural deformation that steel device synchronism causes rolled piece after the upset for bad time.Lifting finger is in the past adopted the synchronous or synchronous design of encoder speed of a power transmission shaft more, and investment is big, equipment is complicated, and workpiece measurement easily changes before and after the upset.By calculating and design, independent one is turned over can't the overturn rolled piece weight of two step pitch length of steel device, has only 6 groups to turn over the steel device and work simultaneously and rolled piece could be dug, and abandons in the design in the past a power transmission shaft synchronously and the synchronous design of hydraulic pressure speed.
3. adopt the chain control of signal, turn over the steel device when being hidden state, can carry out the action of fortune steel, prevent the steel accident of hitting that maloperation causes.
After the utility model related to and is installed in straightener, this device turns over the steel device by 6 to be formed, and the rolled piece after rectifying is turned over steel 90 degree synchronously, carried out the curved up and down of rolled piece and checked, dig check finish after, with turning over the steel device, enter next step operation with the rolled piece original position that overturns back synchronously.If the more stable sampling observation mode that will adopt of the straightening quality of rolled piece is checked bending up and down, need not check when rolled piece is bent situation up and down, turn over the steel device and can hide, can not influence rhythm of production.By on-the-spot practical application, it is obvious to turn over the steel effect, has made things convenient for the inspection of worker to product quality, has reduced the generation of crooked waste product, has improved the product lumber recovery, has good social benefit.
