Description
Technical field
The present invention relates to technical field of steel rolling, belong to a kind of adjusting dynamic balance of high-speed wire spinning machine method.
Background technology
Laying head is the visual plant in the high-speed wire production line unit, and as shown in Figure 1, its primary structure is: motor is delivered to rotatablely moving on the hollow shaft of Laying head 1 by a pair of Helical Bevel Gear.The steel of finishing mill of high-speed wire rod mill roll forming are pinched by pinch roll, enter in the Laying head hollow shaft of High Rotation Speed, pass through spinneret 4 stress deformations again.Steel have become approximate static circle by the high-speed straight-line motion, are scattered on the air-cooled roller-way, become wire coiling, the wire rod that namely is commonly called as again after packing.
Making the parts of wire rod distortion lopping in the Laying head is laying head 2 and spinneret, spinneret 4 is provided with the spinneret standard pipe clamp 3 ' that a plurality of orders are arranged, standard pipe clamp 3 ' is used for fixedly spinneret 4, because spinneret 4 is the elongated tubular of arc, usually, standard pipe clamp 3 ' is distributed on the different curvature radius of spinneret 4.Extremely shown in Figure 4 such as Fig. 2, described spinneret standard pipe clamp 3 ' is U-shaped platy structure, described U-shaped platy structure comprises: be parallel to each other first dull and stereotyped 31 be connected flat board 32, connect link and the pin-and-hole 35 of the sealing of described first dull and stereotyped and the second flat board, described pin-and-hole 35 runs through described first dull and stereotyped the 31 and second flat board 32, the link of described sealing contains described spinneret 4, described spinneret is fixed in the link of described sealing by alignment pin 37 and the screw 33 that passes described pin-and-hole, and fixing by pipe clamp retainer ring 5.
Because laying head 2 be asymmetric cantilever design, complex contour, and the working speed angle is high, equipment centre of gyration line and Mass Distribution center line disalignment therefore very easily occur, and then the phenomenon of initiation Laying head high vibration when working.Vibration when uneven exciting can cause equipment operation increases, and causes the damage of equipment vital part, reduces Laying head service life, affects high-speed rod productivity ratio.Therefore Laying head all will use dynamic balance instrument that the Laying head complete machine is carried out dynamic balance calibration before dispatching from the factory.
Unbalance dynamic when solving equipment operation, the Laying head complete machine after each Laying head manufacturer mainly adopts spot dynamic balance instrument to assembling at present carries out dynamic balance calibration, the method that adopts such as patent CN101642777A.Do not carry out the condition that dynamic balancing is adjusted because device fabrication producer does not all possess under as-rolled condition, the dynamic balancing of Laying head is all proofreaied and correct by each producer under Light Condition before Laying head dispatches from the factory at present.Bearing calibration is probably as follows: under the Light Condition, be when not having wire rod to pass in the spinneret, respectively to laying head weight plane 21 and laying head weight plane 22 usefulness rectify an instrument (spot dynamic balance instrument) proofread and correct, according to the result who proofreaies and correct, laying head 2 on laying head weight plane 21 and laying head weight plane 22, increases respectively counterweight, so that can be issued to balance in working order.
Because what Laying head adopted is the unloaded dynamic balance method of proofreading and correct, there is not wire rod to pass in the spinneret, the Mass Distribution of Laying head had different when wire rod passed spinneret under this and the duty, and unloaded weight of proofreading and correct balance can't consider that Laying head is in rolling real conditions when crossing steel.Therefore proofread and correct that the dynamic balance calibration under the duty requires certain distance on result and the high-speed wire production line.So it is good Laying head test run working order after zero load is proofreaied and correct to occur, and becomes large phenomenon but show vibration values when production line is worked.
The time that Laying head is told steel at production line accounts for more than 90% of its total run time, therefore the Laying head dynamic balancing adjustment of telling under the steel state is seemed particularly important.
