The production line is about meters long and wide. meters high (specific dimensions are subject to the actual product). The rolling mill structure is a fully enclosed, tandem multi-pass cold rolling mill
2. Description of the whole machine
This machine is suitable for ordinary carbon steel, carbon For the processing, rolling and production of knotted steel flat wire rods, German contact online detectors can be optionally used to track and automatically adjust product quality and technical parameters at any time. The whole machine is controlled by C. human-machine interface, and the entire production process control system is monitored in real time. Operation status, fault emergency stop and other systems

Five: Equipment analysis and description
Pay-off stand
①&Passive pay-off, maximum load capacity: tons
②&The frame is welded and formed by steel pipes and steel plates
Shelling machine: main function is to remove oxide scale
Reducing mill:
①&Eliminate embryos The dispersion generated when the material is hot-rolled ensures that the tolerance of the blank entering the rolling mill is within the acceptable range to ensure product quality
②& Reduce the feed specifications to ensure that the blank entering the rolling mill is within the product specification range (one blank can be produced Products of several specifications)
Tension control device
①& Base: steel plate welded and formed
②& One guide wheel is fixed on the shaft at the entrance and exit positions, and the lower guide wheel in the middle& The vertical pressure is provided by the cylinder, the downward pressure is set by the proportional pressure valve, and the position of the guide wheel is given by the encoder
③&Installation position: two rolling mills
④&Function: Tighten the fixed wire direction to prevent left and right The swing produces side bends, and the speed is adjusted. When the tension guide wheel is too high, it means that the speed of the following rolling mill is too fast, and it sends a signal to the following rolling mill to slow down. When the tension guide wheel is exactly parallel in the middle, it means that the speed is just right. When the tension guide wheel If it is too low, it means that the speed of the latter rolling mill is too slow, and a signal is sent to it, requiring acceleration. When the tension guide wheel reaches the lowest point, the whole machine automatically stops
Straightening device
①& Straightening device position: String The feed inlet of the tandem rolling mill and the front end of the wire take-up machine
②&Support frame: steel plate welded and precision machined
③&Usage: used for straightening of blank material feeding and finished flat wire straightening Straight, the gap is adjustable
Two-roll mill structure
①&Frame: Steel plates are spliced and formed, tempered to eliminate stress, processed by high-precision machine tools
②&Roller: Tungsten steel ring insert structure , the hollow uses water circulation to cool down the inside of the roll to reduce the thermal expansion coefficient of the roll, ensure product accuracy, and increase the service life of the roll. During the rolling process, the oil spray nozzle sprays oil to lubricate the roll wire rod, and at the same time takes away the heat generated during rolling, and the roll The bearing seat uses a separate cooling and lubrication system to ensure that the heat generated by the bearings during long-term operation of the rolling mill can be taken away, control and reduce the thermal expansion coefficient of the bearings, and extend the service life of the bearings
③&Each rolling mill has a separate frequency conversion motor with output The power is distributed through the gearbox, and then transmitted to the upper and lower rollers by the transmission shaft respectively
④& Transmission shaft structure: plum blossom key joint + universal joint coupling transmission to ensure concentricity and product accuracy
⑤& Pressure control :Double worm gears and dual servo motors, stepless speed regulation, respectively control the upward and downward pressure of the left and right ends of the roll, which can be pressed down individually or simultaneously with one-button operation
⑥&A set of manual (automatic) horizontal rolling mill The mobile system ensures full utilization of the roll surface and increases the service life of the roll
Four-roll universal precision rolling mill
①& Power: the upper and lower rolls are powered as driving wheels, and the left and right rolls are unpowered passive wheels, but It also has the rolling function,
②&Roller control: Each roll is controlled by a two-roller worm gear reduction servo motor, and can move independently up and down, left and right, and can change into a variety of hole shapes. Rolling products of different specifications only requires changing the hole. Type
③& Control system: Full digital control of the whole machine, real-time data transmission display, one-key tool setting function, anti-roller collision, anti-lock failure alarm, fault display for easy operation, low reliance on workers’ operating experience, and easy maintenance
&Air Knife Oil Removal Device
A specially customized powerful air knife is used to remove the rolling oil on the surface of the wire after two powerful blows, making the surface of the product clean, reducing oil stains, and avoiding The rolling oil is brought out to reduce waste and reduce production costs
Take-up
Detachable take-up, the winding specifications and weight are customized according to the requirements of the buyer
6. Electrical equipment
All control systems of this production line, including electrical, are installed separately in the electrical control cabinet. Modular combination installation facilitates transportation, installation, daily inspection, maintenance, and component replacement
