Abstract

The utility model relates to a wire accumulating type synchronous automatic speed controlling device of a drum, which belongs to a match controlling device for a wire drawing machine of metal product equipment and is used for controlling the speed difference existing between two adjacent drum motors of the wire drawing machine to generate relative movement of a rotating arm. The utility model comprises two drums, two motors, a speed changer, a guiding wheel for wire passing, a frequency converter, a wire drawing die box, two proximity switches, a rotating arm for wire accumulation and a programmable controller. The rotating arm for wire accumulation is arranged at the rim of the top of the drum, the wire drawing die box is arranged beside the drum and the guiding wheel for wire passing is arranged above the drum. The drum is fixed on the axis of the speed changer which is fixed on the motor axis, and both sides of the rotating arm for wire accumulation, which pass through the symmetrical positions of the centre of a circle of the drum, are respectively provided with the two proximity switches. The signals of the two proximity switches are connected into the input terminal of the programmable controller, and the output terminal of the programmable controller is connected to a speed controlling interface of the frequency converter; the output terminal of the frequency converter is connected to the motor, and the input terminal is connected with a power supply. The utility model has simple structure, and is capable of effectively removing the speed difference between the two drum motors.

Description

The long-pending synchronous automaton of line formula spool velocity

One, technical field:

The utility model relates to the synchronous automaton of a kind of long-pending line formula spool velocity, the supporting control device that belongs to metallic article equipment wire drawing machine, the relative motion that is used to control wire drawing machine two adjacent reel motors existence speed differences and produces pivoted arm avoids reversing the influence of drawing to product quality.

Two, background technology:

All there is the speed difference in existing long-pending line formula reel two adjacent reel motors in the steel wire drawing process and produces relative motion, even can of short durationly not produce relative motion by the external speed adjustment, but because the fluctuation and the wire-drawing die size minor variations of load all can be broken this balance, the speed that therefore can't at all eliminate the two winding drum motor is poor.So far, the synchronous automaton of long-pending line formula spool velocity is arranged never, for the usefulness of the speed difference of eliminating wire drawing machine two adjacent reel motors.

Three, summary of the invention:

The purpose of this utility model is to overcome existing long-pending line formula reel two adjacent reel motors in the steel wire drawing process and all exists speed poor, produce relative motion, influence the weak point of product quality, thereby provide a kind of long-pending line formula spool velocity synchronous automaton, be suitable for controlling wire drawing machine two adjacent reel motors and have the speed difference and the relative motion of generation pivoted arm, improve the quality of products, it is simple in structure, and it is effective to eliminate two winding drum motor speed difference.

The purpose of this utility model realizes by following approach:

The utility model includes reel, motor, speed changer, cross wire carrier, frequency converter, Wire drawing die box, near switch, long-pending line pivoted arm and several parts of programmable controller, top sides at reel is amassed the line pivoted arm along establishing, Wire drawing die box is established on the next door, wire carrier was established in the top, reel is fixed on the axle of the speed changer that fixes with motor shaft, and establish two respectively near switch by the symmetric position both sides of the reel garden heart at long-pending line pivoted arm, and insert the input of programmable controller near the signal of switch with two, the output of programmable controller inserts the speed control interface of frequency converter, output and motor with frequency converter joins again, and input and power supply join.

The utility model contrast prior art has following advantage:

1, the utility model is simple in structure;

2, the speed that can at all eliminate between the two winding drum motor of the utility model is poor, realizes that the nothing of long-pending line formula reel is reversed drawing, improves the quality of products;

3, the utility model can be realized the long-pending coil number of reel is quantitatively controlled, and is below or above default long-pending coil number with automatic stopping.

Four, description of drawings:

Fig. 1 is the structural representation of the utility model embodiment, wherein:

1-steel wire, 2-cross wire carrier, the long-pending line pivoted arm of 3-, 4-reel, 5-Wire drawing die box, 6-speed changer, 7-motor, 8-frequency converter, 9-programmable controller, 10-power supply.

Fig. 2 is long-pending line pivoted arm and near the schematic diagram of the position of the switch, wherein for the utility model embodiment Fig. 1 overlooks:

11-is near switch.

Five, the specific embodiment:

The utility model describes in detail below in conjunction with accompanying drawing embodiment:

The utility model embodiment includes reel 4, motor 7, speed changer 6, cross wire carrier 2, frequency converter 8, Wire drawing die box 5, near switch 11, long-pending line pivoted arm 3 and programmable controller more than 9 parts, top sides at reel 4 is amassed line pivoted arm 3 along establishing, Wire drawing die box 5 is established on the next door, wire carrier 2 was established in the top, reel 4 is fixed on the axle with 7 speed changers that fix 6 of motor, and establish two respectively near switch 11 by the symmetric position both sides of the reel 4 garden hearts at long-pending line pivoted arm 3, and insert the input of programmable controller 9 near the signal of switch 11 with two, the output of programmable controller 9 inserts the speed control interface of frequency converter 8, output and motor 7 with frequency converter 8 joins again, and input and power supply 10 join.

During use, with 1 one ends of the steel wire on the reel 4 through long-pending line pivoted arm 3 walk around the top set cross wire carrier 2, the other end pass after Wire drawing die box 5 drawings through set the crossing in another adjacent reel 4 tops wire carrier 2 passes its set long-pending line pivoted arm 3 again and around on this reel 4.After power supply 10 is through 7 runnings of frequency converter 8 drive motors, two adjacent reel 4 runnings, to amass coil number input programmable logic controller 9 near switch 11, write down, control, long-pending line pivoted arm 3 according to two adjacent reels 4 passes through near the two sequential differences near switch 11 simultaneously, can make programmable controller 9 control motor 7 and quicken or deceleration, till the motor 7 speed differences of two adjacent reels 4 are eliminated by frequency converter 8.
