Main Component Structure
1. Mechanical part
The body is welded with Q235B material as a whole; Perform tempering treatment after welding to eliminate internal stress in the material. The body guide rail adopts two hexagonal faces Guide.
2. Transmission type
The transmission gear, crankshaft, and connecting rod are all assembled on the upper part of the press. The main motor is installed on the rear measuring surface of the body, and the flywheel, clutch, etc. are all installed. At the rear position of the fuselage, the flywheel has undergone dynamic balance testing before assembly, and assembly operations can only be carried out after passing the inspection. The gear part adopts a spur gear transmission mechanism, which is made of high-strength alloy steel 42CrMo and subjected to corresponding heat treatment. Dry low inertia clutch/brake. The clutch/brake control system is equipped with an anomaly detection device. All shafts are made of tin phosphorus bronze wear-resistant material with copper alloy.
3. Sliding block
The slider is cast into one piece using HT250 material; The guide rail adopts a two-sided hexagonal right angle guide rail for guidance. There are T-shaped grooves on the bottom surface of the slider and the top surface of the table, which are used for installing molds. The height of the sliding block mold is adjusted electrically by more than 80 tons (including). Adopting hydraulic automatic overload protection system. Lubrication system
The press adopts electric grease lubrication for oil supply, and the distributor is equipped with lubrication blockage alarm, which is interlocked with the machine tool, ensuring safety and reliability. The balancer is a manual thin oil feed pump. Air circuit and balance device system. Adopting a pneumatic slider balance device, the air pressure can be regulated at the air pressure regulating valve; The main air source has a pressure detection alarm function. Electrical part; The electrical system adopts PLC control and is equipped with a powerful human-machine interface, using a well-known brand touch screen as the display. Operating mode; The punching machine is equipped with three operating modes: inch movement, single operation, and continuous operation. The working mode is selected by the conversion switch and centrally controlled by the button.
Safety Precautions
1. Emergency stop button: Press the ''Emergency stop'' button when an abnormality occurs, which is used for emergency stop of the press in case of abnormal operation. The compressor is equipped with two emergency stop buttons. One on the operation control panel and one on the two-handed operation table; When the emergency stop button is pressed at any point, the press machine. All will stop immediately.
2. Two handed operation button: The synchronization time limit for both hands descending is within 0.5 seconds;
3. Abnormal lubrication alarm: The lubrication system adopts a progressive oil distributor, and there is a detection switch on the main oil distributor. In case of blockage or abnormal lubrication frequency, the compressor stops working and is displayed on the touch screen.
4. Overload protection: The slider is equipped with a hydraulic overload protection system to ensure that the press and mold are not damaged due to overload operation; After overload occurs, the slider immediately stops and can only be adjusted and operated by inch or reverse to return to the top dead center for pressure replenishment and operation.
5. Safety photoelectric protection device: Adopting a seismic and anti-interference multi beam photoelectric protection device, installed in a fixed position (adjustable), the light curtain is blocked and immediately sends a stop signal to stop the press. When the photoelectric is abnormal, the device alarms and the slider cannot move up or down. To ensure the safety of personnel, molds, and equipment. The system can set functions such as no return alarm and automatic alarm recovery (system settings require corresponding levels and passwords)
