Abstract
The utility model relates to a quick resetting device for a lower bending roller of a strip tension leveling line (a withdrawal strengthening machine). The quick resetting device is characterized in that an accurate adjustment part at the position of the lower bending roller is installed on the stander of the strip tension leveling line through a motor reducer and lead screw lifting mechanisms, and the two lead screw lifting mechanisms are connected through a spindle; the lower part of an oil cylinder of the quick resetting part is connected with the lead screws of the lead screw lifting mechanisms, and the upper part of the oil cylinder is connected with a lower bending roller device through an oil cylinder connector; gears of the synchronous part are fixed at both ends of an axle, the axle is installed on a bearing seat, and the bearing seat is fixed on the stander of the strip tension leveling line. The quick resetting device has the advantages that the structure is simple, compact and reasonable; the quick resetting of the lower bending roller is met, the production efficiency of the withdrawal strengthening machine set is guaranteed, and the loss of the strip-steel head and tail is reduced; the electric control and the hydraulic control are both available, the labor intensity is small, the automatization is high, the structure is simple, and the manufacture is convenient.
Description
Technical field
The utility model relates to the quick resetting means of following bending roll of a kind of band stretching-bending straightener (straightening machine).
Background technology
For the continuity that guarantees unit work, enhance productivity, in withdrawal straightening stands, generally all adopt seam welder that the welding of different band winding steel toe tail is linked up.Because overlapping mode is adopted in welding; strengthen at the weld belt steel thickness, be not subjected to the safety of scratch and equipment, when being with steel, need bending roll under the straightener is moved down by straightener for protecting the bending roll surface; bending roll and band steel are thrown off, so that the band steel freely passes through.At present, often adopt electronic screw lift to finish this work.Because as the down accurate adjustment of bending roll position, the following bending roll disengage speed of institute is slower again for electronic screw lift, and it is more easily to cause band steel toe overtaking wave to take, and need reduce unit operation speed at the welding line joint place during by the straightening machine for device security.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby the quick resetting means of bending roll under a kind of straightening machine is provided, to guarantee withdrawal straightening stands production efficiency, to reduce the loss of being with the steel toe tail.
Main solution of the present utility model is achieved in that
The utility model comprises straightening machine frame, following bending roll position accurate adjustment parts; Feature is that accurate adjustment parts in bending roll position under adopting, quick reset components and synchronization section connect to form; Described bending roll position accurate adjustment parts down adopt motor reducer and screw lift structure to be installed on the straightening machine frame, link to each other with connecing axle in the middle of two screw lift structures;
Described quick reset components is made up of oil cylinder and oil cylinder connector, and the oil cylinder bottom is connected with the screw mandrel of screw lift structure, and oil cylinder top links to each other with following bending roll device by the oil cylinder connector;
Described synchronization section is made up of gear, tooth bar, axle, bearing block assembly, and gear is fixed on a two ends, and axle is installed on the bearing block assembly, guarantees two ends gear synchronization action, guarantees the steady lifting of bending roll down; Bearing block is fixed on the straightening machine frame.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Satisfied resetting fast of bending roll under the straightening machine, guaranteed withdrawal straightening stands production efficiency, reduced the loss of band steel toe tail; Electronic, hydraulic control, labour intensity is little, and the automaticity height is simple in structure, easily manufactured.
Description of drawings
Fig. 1 is the quick resetting means front view of bending roll under the utility model.
Fig. 2 is the quick resetting means vertical view cutaway drawing of bending roll under the utility model.
Fig. 3 is the quick resetting means side view of bending roll under the utility model.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly by down bending roll 1, oil cylinder connector 2, oil cylinder 3, axle 4, connect axle 5, screw lift structure 6, motor, reductor 7, tooth bar 8, gear 9 and bearing block assembly 10, straightening machine frame 11 etc. and form.
As Fig. 1～shown in Figure 3: the utility model adopts down bending roll position accurate adjustment parts, reset components, synchronization section connect to form fast.
Described bending roll position accurate adjustment parts down are made up of motor reducer 7 and screw lift structure 6, motor, reductor 7 are direct-connection type, link to each other with connecing axle 5 in the middle of two screw lift structures 6, to guarantee two screw lift synchronization actions, drive screw lift structure 6, the height and position of bending roll under the accurate adjustment by motor reducer 7.Motor reducer 7 and screw lift structure 6 are installed on the straightening machine frame 11.
Described quick reset components is made up of oil cylinder 3 and oil cylinder connector 2, and oil cylinder 3 bottoms are connected with the screw mandrel of screw lift structure 6, moves up and down fast by bending roll 1 under the quick-expansion drive of piston rod.Oil cylinder 3 tops link to each other with following bending roll device by oil cylinder connector 2.
Described synchronization section is made up of gear 9, tooth bar 8, axle 4, bearing block assembly 10 etc., and gear 9 usefulness flat keys are fixed on axle 4 two ends, guarantee two ends gear 9 synchronization actions, guarantee the steady lifting of bending roll 1 down.Gear 9, axle 4 are installed on the bearing block assembly 10, and bearing block assembly 10 is fixed on the straightening machine frame 11.
As shown in Figure 1: during the withdrawal straightening stands operate as normal, oil cylinder 3 piston rods reach range, drive the screw lift screw rod by motor reducer and move up and down, and bending roll is to the correct position of technological requirement under the accurate adjustment.The welding joining seam is when the bending roll, and oil cylinder 3 piston rods withdrawal minimum stroke descends bending roll 1, bending roll is thrown off with the band steel down, is with steel freely to pass through fast.
