Abstract
This patent belongs to along the straight -line bending metal sheet, specifically discloses a veneer reeling machine arresting gear, and its characterized in that includes frame, stator, rotor, current condenser and is used for stopping the upward electromagnetic braking ware of roller, the rotor is fixed on hollow in the roller, the stator is fixed in the frame, and is located the rotor, rotor, stator all link with the current condenser electricity. Under the normal condition, go up the roller and when rotating, drive the rotor and rotate, because the stator is fixed in the frame, then produce magnetism between stator and the rotor and feel the wire -electrode cutting, produce the electric energy to the storage is in the current condenser. When the circularity of roll board is not conform to the requirement, stop the power supply to utilize the electric energy in the current condenser to start the electromagnetic braking ware simultaneously, thereby will go up the roller stop. When the roller rotates in the utilization of this scheme, produce the electric energy to collect through the current condenser, be used for the electromagnetic braking ware, thereby it can stop going up the roller to need not extra electric power.
Description
Technical field
This utility model belongs to linearly crooked metal sheet, particularly relates to a kind of veneer reeling machine brake unit.
Background technology
Veneer reeling machine is a kind of common apparatus that sheet metal is rolled into tubular, arc or other shape workpieces.According to 3 principles becoming circle, utilize the change of workpiece relative position and rotary motion to make sheet material produce continuous print plastic deformation, meet the requirements workpiece obtaining shape.The most commonly used is three rolls plate bending machine, and it mainly includes top roll, lower roll and limit roller, and top roll is main drive roller, is connected with power source, lower roll vertical displacement movement, in order to clamping sheet material, and is engaged with upper roll gear by lower roll gear；Limit roller is made to incline elevating movement, has pre-bending and volume circle dual-use function.Compact conformation, operates easy to maintenance.Curly course must assure that curling circularity, but, in actual mechanical process, it may appear that the undesirable roll bending of circularity of a small amount of roll bending.The top roll at this time, it may be necessary to stop operating, manually carries out rolling repair to roll bending, to ensure that the circularity rolling out steel plate (roll bending) meets the requirements.Existing veneer reeling machine is all promote top roll to stop operating by disconnection power source, and due to inertia, top roll cannot stop immediately, may proceed to rotate a period of time, thus causing that the circularity of roll bending further offsets from, can strengthen the follow-up reparing process to roll bending.
Therefore, it is badly in need of a kind of device that can stop veneer reeling machine immediately, is rotated further with top roll after avoiding stopping power source.
Utility model content
The purpose of this utility model is providing a kind of veneer reeling machine brake unit, is rotated further with top roll after avoiding stopping power source.
In order to achieve the above object, base case of the present utility model is: veneer reeling machine brake unit, including frame, stator, rotor, electric storage means and for stopping the electromagnetic brake of top roll, described top roll is hollow roller, described rotor is fixed in the top roll of hollow, described stator is fixed in frame, and is positioned at rotor, and described electromagnetic brake, stator are all electrically connected with electric storage means.
The principle of this base case is in that: under normal circumstances, and top roll is when rotating, and rotor driven rotates, and owing to stator is fixed in frame, then produces magnetic induction line cutting between stator and rotor, produces electric energy, and be stored in electric storage means.When the circularity of roll bending is undesirable, stops power source, and utilize the electric energy in electric storage means to start electromagnetic brake simultaneously, thus top roll is stopped.
Having the beneficial effects that of this base case: when this programme utilizes top roll to rotate, is produced electric energy, and is collected by electric storage means, for electromagnetic brake, can be stopped by top roll from without extra electric power.The corresponding time of electromagnetic brake is short, can stop veneer reeling machine after power on/off immediately.
Scheme two: based on this, scheme is preferred, described electromagnetic brake includes the first grip unit and the second grip unit, described first grip unit, the second grip unit all include connecting rod, electric magnet and friction plate, described electric magnet and friction plate are respectively arranged at the two ends of connecting rod, connecting rod in described first grip unit and the second grip unit is hinged, and described electric magnet and electric storage means are electrically connected.During electric magnet energising, the first grip unit and the electric magnet in the second grip unit produce magnetic force, attract each other together, thus driving friction plate to be held tightly by top roll, reach to stop the purpose of top roll.
Scheme three: this is the preferred of scheme two, replaces with iron block by the electric magnet in the first grip unit or the second grip unit.Relative to electric magnet, the cost of iron block is lower, but, still can reach the purpose that friction plate attracts each other.
Scheme four: this is the preferred of scheme three, and described iron block is provided with antirust coat.Antirust coat can effectively completely cut off iron block and air contact, it is to avoid the problem that iron block cannot attract each other with electric magnet because of getting rusty.
Scheme five: this is the preferred of scheme two or scheme four, and the pin joint between described first grip unit, the second grip unit is away from electric magnet.According to lever principle, the power between electric magnet and electric magnet (or iron block) is amplified, and braking effect is better.
Scheme six: this is the preferred of scheme five, and described friction plate is curved.The friction plate of arc and the contact surface of top roll are bigger, and frictional force is then also more big, good braking effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model veneer reeling machine braking device embodiments 1.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: top roll 10, rotor 20, stator the 30, first friction plate 41, first connecting rod the 42, first electric magnet the 43, second friction plate 47, second connecting rod the 48, second electric magnet 49.
Embodiment 1
As it is shown in figure 1, veneer reeling machine brake unit, including frame, stator 30, rotor 20, electric storage means and for stopping the electromagnetic brake of top roll 10.Top roll 10 is hollow roller, and rotor 20 is arranged in the top roll 10 of hollow, and stator 30 is welded in frame, and is positioned at rotor 20.Electromagnetic brake, stator 30 are all electrically connected with electric storage means.
