The screwdown device comprises a bracket, wherein two motors are arranged at the two ends of the bracket, and are respectively connected with horizontal input shafts through couplings; worm rods are respectively arranged on the two input shafts; the two worm rods are respectively connected with worm wheels in a worm wheel reduction gearbox; the horizontal worm wheels and vertical screw rods are arranged in the worm wheel reduction gearbox; the screw rods are in fit connection with the worm wheels; thread sleeves fitting the screw rods are arranged at the lower end of the worm wheel reduction gearbox; and pressing pads are respectively arranged at the lower ends of the two screw rods.
Description
Technical field
The present invention relates to turbine apparatus technical field, be specially a kind of screwdown gear.
Background technology
In cold-rolling mill technical field, milling train has the multiple types such as duo mill, three-high mill, four-high mill, milling train there are working roll, intermediate calender rolls, backing roll etc., roller, after one period of service time, needs to carry out replacement operation to it, needs the pressing operation carrying out roller in Renewal process, general pressing operation is all manually carry out, depressing position cannot ensure that accurately efficiency is lower, and pressure effect is undesirable.
Summary of the invention
In order to solve the problem, the invention provides a kind of screwdown gear, it accurately can realize the pressing operation of roller, simple and convenient, raises the efficiency.
Its technical scheme is such: a kind of screwdown gear, it is characterized in that, it comprises support, described support two ends arrange two motors, two described motors connect horizontally disposed power shaft respectively by shaft coupling, two described power shafts arrange worm screw respectively, two described worm screws connect the turbine in worm gear reducer respectively, horizontally disposed turbine and vertically disposed screw rod is comprised in described worm gear reducer, described screw rod and described turbine are connected, described turbine reduction box lower end arranges the thread bush coordinated with described screw rod, two described screw rod lower ends arrange pressure pad respectively.
It is further characterized in that, described support comprises two bracing frames be arranged in parallel, and two described motors are arranged on two support frames as described above respectively;
Support frame as described above arranges conveyer belt, and described motor connects described conveyer belt;
Described shaft coupling is positive coupling;
Described pressure pad is copper packing;
Described screw rod arranges die stop by screw;
Described die stop upper end arranges the hold-down nut of cooperation.
After adopting structure of the present invention, support two ends arrange two motors, two motors connect horizontally disposed power shaft respectively by shaft coupling, two power shafts arrange worm screw respectively, two worm screws connect the turbine in worm gear reducer respectively, horizontally disposed turbine and vertically disposed screw rod is comprised in worm gear reducer, screw rod and turbine are connected, two screw rod lower ends arrange pressure pad respectively, two machine operation, two power shafts are driven to rotate by shaft coupling, worm screw passes to turbine, turbine passes to screw rod, while screw rod rotates in thread bush, move down, two screw rods move down simultaneously, roller is depressed by pressure pad, ensure that the pressing operation accurately realizing roller, simple and convenient, raise the efficiency.
