Linear wire drawing machine

I. main technical parameters: 1. maximum incoming line strength: ≤ 450mpa; 2. Maximum incoming wire diameter: ф Ф5.5mm；; 3. Minimum outlet diameter: ф Ф2.5mm；; 4. Speed: design speed 10m/s, economic operation speed 8m/s; 5. Motor: Hebei Taili AC broadband motor is adopted. The power of the first motor is 22KW, and the rest is 18.5KW. Total power 96kw. 6. Wire drawing machine frame: (1) 20mm steel plates shall be used for the panel and rear riser of the rack, and thick-walled square tubes shall be used for the rack, which shall be welded by carbon dioxide gas shielded welding wire. (2) Water, electricity, gas and control buttons and emergency braking device (pull rope or mushroom button) are set at the front of the rack. (3) All protective covers are closed. (4) 40Cr and 42 CrMo main shafts are forged and quenched. 7. Drum: The diameter of the drum is 560mm, the drum is made of ZG45 steel, the working surface is sprayed with tungsten carbide powder, and the drum is guaranteed for 2 years. Total drum height is 317mm, spraying height is 120mm, thickness is 0.5mm, and hardness is HRC60. 8. Mould box: It adopts weldment, cooling water chamber and lubricating powder chamber, which is installed reasonably and adjustable from top to bottom and left to right. The mold cooling is direct water cooling, and a wire pressing device is provided to reduce the vibration of the wire. 9. Tension device: pneumatic back tension tuning is adopted, and the tension is constant and adjustable. Sensor angular displacement non-contact mode is adopted. 10. transmission mode: high-efficiency narrow v-belt transmission is adopted, and LYC bearing is adopted as the bearing. 11. cooling system: (1) Self-descaling narrow slot water cooling is adopted inside the drum, and an observation mirror is provided. (2) The mold cooling is direct water cooling, and an observation mirror is provided. 12. safety system: (1) totally enclosed protective device; (2) Automatic shutdown in case of disconnection; (3) The emergency stop switch can realize rapid stop conveniently and quickly; (4) The mushroom emergency stop button is set on the main console, take-up and take-off machine. (5) The wire drawing machine is designed with lighting system, so that the current situation of wire drawing can be clearly seen on cloudy days or at night. The lighting switch is set on the control panel of each machine, which can be easily turned on or off at any time. 13. Description of control system: (1) working mode: all digital control is realized, and high-grade components are adopted, which has strong anti-interference ability and fast operation. Each machine is provided with some functions such as starting, front linkage, rear linkage, start, stop and emergency stop, etc. The man-machine interface of the main console has functions such as length preset display, speed preset display, fault inquiry and equipment status display. (2) It can display the running status of each drawing drum; (3) It can control the linkage of each wire drawing reel and the single machine of the take-up; (4) The running speed can be adjusted as a whole; (6) Automatic alarm can be given in case of failure, and the position and reason of possible failure can be displayed. (7) finishing on a wire drawing machine; Single machine punctuality, left-hand jog, right-hand jog, single machine anti-jog, left-hand (right-hand) run and stop; Adjust the tension of tuning roller, and adjust the cooling water quantity of mold box and drum. (8) Completion of operation desk: general start, general stop, emergency stop, acceleration, deceleration, fault indication, meter counting and reset. (9) Touch screen completion: die matching (wire diameter) setting, speed setting, length setting (automatic stop when fixed length is in place), die jumping setting, inching speed setting, fault content display and actual running speed display.
