5. Technical requirements

5.2.1 main structural features I

(1) Built in 9 processing modes, each product can select the most suitable processing curve for parts processing, So as to achieve high efficiency and high precision.

(2) Compared with the traditional punch, the structure is simple, the mechanical transmission efficiency is high, and the maintenance cost is low

(3) According to the characteristics of the product / material, the forming speed of the punch can be reduced during the material processing, so as to achieve the optimal forming speed of the product / material. So as to reduce the vibration, reduce the noise of stamping, improve the accuracy of products and prolong the service life of the die.

(4) According to different products and different heights, the stroke of punch can be set arbitrarily, which greatly shortens the stamping time and improves the efficiency.

Built in 9 processing modes

5.2.2 main structural features 2

(1) High frequency quenching treatment of slide guide rail, hardness above hrc45,

Advantages: greatly improved wear resistance. (other manufacturers do not have high frequency quenching treatment)

(2) The surface roughness of the slider and guide rail is as high as ra0.4-ra0.8,

Advantages: high precision and low wear. (no quenching and grinding treatment from other manufacturers)

(3) The flatness of slide guide rail is 0.01mm/m, and the precision is high.

Advantages: the accuracy is greatly improved. (other manufacturers above 0.03mm/m)

(4) All our air circuit components are SMC Japan. (other manufacturers generally use domestic products).

(5) We adopt American MAC brand for air spraying solenoid valve, which has high sensitivity of air spraying reaction.

(6) The crankshaft made of 42crda is the best in China

Advantages: the strength is 30% higher than that of 45 steel, and the service life is longer. (other manufacturers generally use 45 steel)

(7) The copper sleeve is made of zqsn10-1 (Tin Phosphorus Bronze) (similar to Aida copper sleeve). Other manufacturers adopt bc6 (high strength brass, also known as 663 copper), has 50% higher strength (surface pressure) than ordinary copper, and is more wear-resistant and durable, Longer precision and longer service life.

(8) All our piping is Φ 6, and the oil circuit is smooth and not easy to be blocked. (other manufacturers usually use Φ 4)

(9) The ball seat adopts Japanese TM-3 sintered copper alloy (same material as Aida)

Advantages: the probability of biting is greatly reduced (general manufacturers are cast iron).

5.2 Main component structure

⑴ Mechanical parts

The frame is welded with Q235B material. After welding, tempering is carried out to eliminate the internal stress of the material. Fuselage guide rail position with two corners of six guide road.

⑵ Transmission type

The transmission gear, crankshaft and connecting rod are assembled on the upper part of the press. The main motor is installed on the rear measuring surface of the frame, flywheel, clutch, etc

In the position of the rear side of the frame, the flywheel has been tested for balance before assembly.

The gear part adopts straight tooth transmission mechanism, and its material is made of high-strength alloy steel 42CrMo, and the corresponding heat treatment is carried out.

Dry low inertia clutch/brake. The clutch/brake control system is equipped with an abnormal detection device.

The bottom surface of the slide block and the top surface of the table have T-groove, which is used to install the mould. The height of sliding block is adjusted by electric motor over 80 tons (including).

Adopt hydraulic automatic overload protection system.

⑷Lubrication system

The press is lubricated with electric butter and equipped with low oil level alarm system, so it is safe and reliable. The equalizer is: manual butter feeding pump.

⑸ Balancing device system

Adopt air pressure type slide block balance device, Air pressure can be controlled at the air pressure regulating valve.

⑹ Electrical part

The electrical equipment is controlled by PLC, equipped with powerful human-machine interface, and displayed by the touch screen of famous brands.

Placed on the main operation panel, the following functions can be achieved:

①The touch screen displays Chinese characters (or switch between Chinese and English), which is simple and easy to understand, and displays various data parameters of the press, such as the number of strokes, electronic CAM Angle, etc.And the corresponding data can be set through the touch screen;

② Display the working flow of the press, so that the operator can operate the press more easily，and has the main flow state indication；

③ Operation and failure information display, so that operators and maintainers more quickly to solve the press problems, reduce the downtime;

④ PLC input/output point real-time monitoring function;

⑤ Set the product count screen, which can display the current product count in real time, and set the target number of work pieces.

⑥ Electric control press adopts three-phase power supply, 380V,50Hz.

⑦ The main motor is equipped with thermal overload and zero speed anti-reversal protection.

⑧ The realization of each function of punch control has corresponding safety chain. The panel is equipped with fault indicator light and reset button to complete the function of reset after fault confirmation.

5.3 Mode of operation

Press set inching, single, continuous three operating modes. The working mode is selected by the switch and centrally controlled by the button.

5.4 Safety measures

⑴ Emergency stop button: press "emergency stop" button in case of abnormal operation of press. The press has three emergency stop buttons.

One on the operation control panel, one on the column, one on the two-handed operation table; Press any of the emergency stop buttons and the press will stop immediately. The position of the emergency stop button on the column is about 1.2 meters from the ground, which meets the requirements of ergonomics；

⑵ Two-hand operation button: two-hand downward synchronization time limit is 0.2-0.5s;

⑶ Overload protection: the slide block is equipped with hydraulic overload protection system to ensure that the press will not damage the press and die due to overload.

Overload after the slider that stays at the bottom dead point, can only use inching, reverse return to the top dead point for readjustment and pressure, work.
