Abstract
The utility model relates to a longitudinal conveying device for a steel rail turnout precision forcing production line, which comprises a fixed frame body and a moving frame body, and is characterized in that: a driving variable-frequency motor is fixed on the moving frame body; the output shaft of the driving variable-frequency motor is connected with a driving gear; the driving gear is meshed with a rack fixed on the fixed frame; and the connecting shaft end of the driving gear is connected with a rotary coder of an electric control system through a synchronous belt wheel. The longitudinal conveying device has the advantage that accurate position control is realized by intercepting a driving gear rotation angle signal during the rotation of the driving gear by a programmable logic controller (PLC) and comparing the signal with a preset distance for the rotation of the motor. The use of an electrical braking resistor to brake the variable-frequency motor can consume the action of a resistance to brake a current generated in a circuit and can counter act the adverse effect generated by a forcing resistance. The longitudinal conveying device with a simple structure is safe and reliable and simple and convenient for installation and debugging and convenient for post maintenance.
Description
Technical field
The utility model belongs to the hydraulic press technical field, particularly relates to the vertical transport of a kind of rail track switch forging production line.
Background technology
In recent years, increasing to the demand of track along with railway transportation develops to high-speed overload, the quality of requirement is increasingly high, requires the efficient of production also more and more faster.The rail forging equipment is one of the equipment of the processing rail of Rail Production enterprise, and it can realize the technological requirement to product hot-die compression mouldings such as various tongues, wing rail and various heart rails by means of various moulds.Because the length dimension of rail is bigger; It is that it carries rail that the rail forging equipment just needs pay-off; And forging equipment is repeatedly accurately forging and pressing such as rail head, the web of the rail, the flange of rail to rail, therefore the level of rail, vertical, upset is carried and has been proposed higher required precision and higher efficient requirement.Vertical transport adopts the brake type driven by servomotor in the prior art; Because inevitably there is reverse mobile counter-force in rail in forging process; Accumulate on the driving shaft of servomotor; Can cause the instability of servomotor braking, above-mentioned mobile counter-force builds up when serious, the possibility that can cause servomotor to burn.There is trouble of manufacturing, installation, debugging, later maintenance in servomotor simultaneously, element long shortcoming of procurement cycle.
Summary of the invention
The utility model provides a kind of simple in structure, precision that can guarantee vertically to carry rail for solving the technical problem that exists in the known technology, also can avoid the vertical transport of rail track switch forging production line that the servomotor braking is unstable and burn simultaneously.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The vertical transport of rail track switch smart end production line; Comprise fixing bracket body and movable support body; It is characterized in that: be fixed with the drive variable frequency motor on the said movable support body; Said drive variable frequency motor output shaft connects driven wheel, and said driven wheel is meshed with tooth bar on being packed in fixing bracket body, and said driven wheel connects axle head to be passed through synchronous pulley and be connected with the rotary encoder of electric control system controls.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; To be that the braking of variable-frequency motor is adopted electric, resistive braking adds accurate rotary encoder combination; The reason that in forging process, flows owing to the mold cavity extrusion metal; And when producing converse power effect and acting on the drive motors through movable support body, braking resistor can consume converse power effect and make the electric current that produces in the circuit, reaches the braking purpose.So not only can guarantee vertically to carry the precision of rail; But also can avoid reverse mobile counter-force in the rail forging process that the brake type driven by servomotor brings, accumulate to the possibility that causes the unstable of servomotor braking and burn servomotor on the driving shaft of servomotor.Adopt variable-frequency motor simple in structure safe and reliable, the manufacturing Installation and Debugging are easy, and later maintenance is more convenient, element procurement cycle weak point.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, movable support body; 2, variable-frequency motor; 3, driven wheel; 4, fixing bracket body; 5, tooth bar; 6, synchronous pulley; 7, rotary encoder.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2, the vertical transport of rail track switch forging production line comprises fixed mount 4 and movable support body 1.Be fixed with drive variable frequency motor 2 on the said movable support body 1; Said drive variable frequency motor output shaft connects driven wheel 3; Said driven wheel is meshed with tooth bar 5 on being packed in fixing bracket body 4, and said driven wheel connects axle head and is connected with the rotary encoder 7 of electric control system controls through synchronous pulley 6.Thereby realize vertical conveying of movable support body through the rotation of driven wheel 3; Driven wheel connects axle head and links to each other through the accurate rotary encoder 7 of synchronous pulley 6 with electrical system control; When driven wheel rotates, rely on PLC intercepting driven wheel rotary angle signal and setpoint distance to compare, realize Accurate Position Control in order to the motor spinning movement.The electric braking resistive braking is adopted in the braking of variable-frequency motor; When in forging process,, inevitably produce converse power effect because the mold cavity extrusion metal flows; Be delivered on the movable support body; Thereby act on the drive motors, braking resistor can consume converse power effect makes the electric current that produces in the circuit reach the braking purpose, and can offset and forge the adverse consequences that converse power produces.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the utility model.
