Overview of the wire drawing machine device

The high-speed wire drawing machine is mainly used for drawing copper wire, and its main electrical drive part is composed of wire drawing motor, wire connecting motor and wire cutting motor. Other auxiliary parts of the equipment include pendulum rod (tension frame), positioning wheel, wire wheel, wire rod, etc. The wire drawing machine drives the stretching wheel to run, the four-stage stretching wheel is linked with the belt to realize metal stretching, and the wire drawing motor is winding. The general situation and functional requirements of the equipment are as follows: 1.1 The basic parameters of the equipment: Product name: high-speed filament stretching machine drawing motor (KW): 11/4P wire connection motor (KW): 4/4P incoming wire diameter (mm): φ 0.6 ~ 1.20 outlet diameter (mm): φ 0.08 ~ 0.32 Maximum mechanical speed (m/s): 2500 (Max) tensile frame: 5K ω 1.2 Technical parameters and requirements: ◎ Synchronization requires acceleration when the equipment starts; ◎Keep the tension constant when the equipment is running; ◎Shutdown synchronization, no broken wire, tension relaxation; ◎Disconnection protection required for safe production of equipment; ◎ Touch thread function; ◎ External button starts running; ◎ Running speed display; ◎The diameter ratio of empty disc to full disc is about 1:3; ◎The weight of the whole plate is about 50kg; ◎The higher working frequency is about 70HZ.

Wire drawing machine system composition

◎According to the equipment of the wire drawing machine, the following models and components are selected as the electrical transmission equipment INV1: drafting inverter S011Z3 INV2: winding inverter S004G3 braking resistance: ◎ The drafting motor adopts S011Z3 type inverter, and the winding motor adopts S004G3 type special winding frequency converter (equipped with external dynamic resistance). ◎The operation command and output frequency signal of the host INV1 are used as the operation instructions and frequency instructions of the host INV2 to achieve synchronous operation. The reverse braking of the larger weight platter to prevent wire breakage has a worldwide function, in which the voltage signal output by the pendulum rod is used as the feedback signal during the threading operation, and the internal variable PID is used for correction control, and three unique crystal inverters are used to connect the series line to carry out the speed curve prediction graphical operation, so as to realize the fixed speed winding and meet the process requirements. 

(1) The operator of the wire drawing machine must hold the qualification certificate for the operation of the drawing machine, and it is strictly forbidden to operate the machine without a license.

(2) The operator must carry out production and processing operations in the designated equipment. It is strictly forbidden for non-machine personnel to operate on the machine or operate in series.

(3) The operator must be familiar with the basic technical parameters and performance indicators of the equipment.

Operators must be loyal, conscientious and responsible, and proficient in operating, maintaining and maintaining the equipment. Operators must constantly sum up and learn and improve their own quality.

(1) The operator must wear gloves to prevent the workpiece from burning his fingers and affecting the quality of the product.

(2) Before starting the machine, carefully check the air supply of the equipment (5kg/cm2), whether there is any leakage in the air supply pipeline, and discharge the water in the air filter.

(3) Correctly install the drawing belt (the direction of the arrow in the drawing belt should be consistent with the direction of the arrow on the drawing roller). Double-check that the upper and lower housings and lifting screws are well lubricated to ensure that no one is unloading the load to the front before starting.

(4) After the equipment is started, it should be immediately checked whether the abrasive belt swing is within the required range and whether there are other abnormal phenomena, otherwise it should be adjusted or stopped immediately.

(5) It is strictly forbidden to start the drawing machine and the soot blower at the same time, and it is strictly forbidden to leave the operator after starting. It is strictly forbidden for the workpiece to be placed directly on the conveyor belt without a supporting plate, and it is strictly forbidden for the wooden supporting plate to directly loosen the working parts and pull out without a supporting plate, so as to avoid damage to the conveyor belt and the workpiece flying out of the injury.

(6) When two people are working, the operator behind the equipment shall not export the wire drawing machine, so as not to fly out of the workpiece.
