Half bow type of press technical characteristics
Press the beams and columns of overall, base, slider, workbench, mattress, clutches and brakes, driving system and hydraulic pressure lubrication and pneumatic system and electrical control system, etc.
A, press machine parts
For steel welding machine body parts, the top box structure, pole, base through four tighten screw with hydraulic pre-tightening forms, and closed frame beams, base through the key position, guarantee the precise and reliable airframe framework. The beams and columns, slider, workbench, base, such as welding structure of large cushion adopts CO2 gas shielded welding type welding structure, box of stiffened plate and welding grooves symmetry position, welding technology has ideal. Each big after welding stove in the stew in hot aging treatment of eliminating stress, ensure long-term stable precision machine operation.
Second, the pressure of the main transmission system
Main transmission driver using upper drive, eccentric or more long rail link drive, to improve the plunger orientation. The slide motion characteristics, in the drawing interval velocity and low, and the smooth connecting rod driving mode can satisfy the requirement of stamping process and improve stamping mould quality and prolong life. The vertical shaft, symmetric positive pressure machine with high precision, high grade decorate, the word gear transmission gears, big gear differential rotating cavity note oil by spokes, ensure the smooth movement compressor. Comprehensive clearance fit and transmission chain operation minimum noise.
Third, clutch/brake
Dry type clutch and brake using single plate, block, with low inertia, balloon structure. With reliable, action quick, convenient maintenance and long service life. Clutches and brakes using thermodynamic valve control, and through the special loop adjustment and braking coordination, ensure clutches and brakes action safe and reliable. Brake pipe with abrupt stop valve, pressure machine in emergency situations timely braking. Wet clutch brake another remarkable characteristics is reflected, high thermal performance repositioning, very good, in motion and opened to the tooth under the condition of high frequency, and no dust, particularly for equipment and pollution, low inertia, the small.
Four, rotary CAM synchronous machine and synchronous drive letter
Synchronous transmission system, composed of a group of the gear transmission, ensure synchronous drive shaft and the sender of crank synchronous rotation, to ensure the control signal and the slider synchrony movement. Operates trip indicator, slider synchronous machine and receiver by post, the operating instructions on disk slide Angle (instructions), slider trip down dead spots (light instructions) and convenient operation.
Five, the slider
Slider adopted eight surface structure, the guide rails orientation on loaded with adjustable wear-resisting, guarantee the accuracy, convenient adjustment guidance. The height adjustment slider closed at different heights: in order to adapt to the mold, the slider adjusting mechanism with. In order to prevent the loading mode changes, the height of the slider adjustment function of braking motors. In the process of adjustment slider, through the revolving encoder to mold in high numerical display screen, the accuracy of 0.1 mm. Input data can be adjusted for height, loading mode slider adjusting speed 50 / min. Adjust the slider, floor, with limit switches, safe and reliable. Tooling adjustment preload stress can reach 300kn, simple and reliable, easy to adjust to die. Hydraulic overload protection device: liquid gas equilibrium, travel, overload protection mm after recovery time does not exceed 3 minutes, compressor, slider during normal working pressure oil pressure and protect the cavity of the gas pressure unloading valve, once the load balancing achieve predetermined 110% of tonnage, protect cavity pressure oil, unloading valve opens unloading, compressor, main operation to immediately stop running on the red indicator, fine-tuning slider back on automatic blocking zone, and then quickly to establish pressure balance ", "liquid conform to operate reset button rear can restart press machine, provide safety protection. |
