Solid Frame Double Crank Mechanical Press (STE series)
Main performance characteristics:
High rigidity (deformation) of the body and slider 1/8000: small deformation and long accuracy retention time.
Use pneumatic wet clutch brake (integrated type): environmental protection, no pollution, low noise, long service life.
The slider adopts four-corner and eight-sided guide path, which can carry a large eccentric load to ensure the long-term and stable maintenance of stamping accuracy.
Slider guide rail adopts "high-frequency quenching" and "rail grinding process", with little wear, high precision, long precision retention time, and improved mold life.
Use forced thin oil circulation lubrication device: energy saving, environmental protection, with automatic alarm function, can increase the number of stamping by adjusting the oil volume.
The crankshaft is made of high-strength alloy material 42CrMo, which is 1.3 times stronger than 45 steel and has a longer service life.
The copper sleeve is made of tin-phosphorus bronze ZQSn10-1, whose strength is 1.5 times higher than that of ordinary BC6 brass. It adopts a highly sensitive hydraulic overload protection device, which can effectively protect the service life of the punch and die.
Standard Japanese SMC pressure regulating valve, lubricator, air filter.
Standard Japanese NSK bearings and Japanese NOK seals.
Standard configuration of German Siemens touch screen and Siemens motor.
Optional mold cushion (air cushion).

Other straight side double crank presses
Daya press: with platform and safety fence, convenient for clutch maintenance and change of cooling oil, main motor belt is loose and easy to adjust, and convenient for subsequent maintenance. Safer and more convenient.
Other press: Without maintenance platform. Clutch maintenance, replacement of cooling oil, loose adjustment of main motor belt, etc. which can only be completed with the assistance of forklift, which is not convenient for subsequent repair and maintenance. There are some potential safety hazards.
Daya press: Daya press adopts four corners and eight sides to surround the guide rail. In the stamping forming position, the slide guide rail is included by all the guide rails on the table body. This kind of guide rail has the characteristics of high stamping accuracy, strong anti eccentric load capacity, small rail wear and long precision retention time.
Other press: the guide rail with semi enclosed structure as shown in the right figure is adopted. During the stamping process, there is a section of guide rail exposed. During the stamping process, the slide guide rail is easy to tilt, with poor anti bias load capacity, large rail wear, short precision retention time and high maintenance cost.
Daya press: the distance between the two points of force application is more than 60%;Advantages: the larger the distance between the two force application points, the greater the eccentric bearing capacity; the larger the distance between the two force application points, the higher the design cost.
Other press: the distance between the two points is generally less than 50%; Disadvantages: the smaller the distance between the two force application points, the smaller the eccentric bearing capacity. The guide rail is easy to tilt, the guide way is easy to wear, and the precision of guide rail is poor.
Daya press: forced thin oil circulation system, energy saving, can be recycled, fan thermal performance is good, compared with grease lubrication can be increased by 5-10 beats per minute.
Other press: electric grease pump, grease can not be reused, no advantage of forced thin oil circulation system.
Daya press: when the stroke length is the same, the forced thin oil circulation system has higher efficiency, compared with grease lubrication, it can increase 5-10 beats per minute. Strictly follow the Japanese JIS level 1 standard; the Japanese JIS level 1 standard is higher than the Taiwan CNS level 1 standard.
Other press:electric grease pump, grease can not be reused, no forced oil circulation system advantages. according to Taiwan CNS level 1 standard

Guide rail of Daya punch press
1.High frequency quenching process: hardness above hrc48;
2. Grinding process of guide rail: the surface finish can reach ra0.4-ra0.8 (mirror surface), flatness, parallelism and verticality within 0.005mm/ ㎡.
3.The machine tool has the advantages of small wear, high precision, long precision maintenance time, long service life and low energy consumption.
Other press guide railno quenching process; milling processing, surface roughness ra1.6-ra3.2, flatness, parallelism, perpendicularity more than 0.3mm / ㎡

other press crankshafts
Daya punch press: the crankshaft is made of high strength alloy 42CrMo Advantages: the strength is 1.3 times higher than that of 45 steel, the service life is long, the wear resistance is good, the wear is small, and the precision is maintained for a long time.
Other presses: made of 45 steel, Disadvantages: low cost，the strength and wear resistance are not comparable to 42CrMo
Oil way of DAYA punch PRESS: Φ 8 is used for oil pressure lubrication piping.
Advantages: long pipeline, large diameter is not easy to block, break, ensure the safety of lubricating oil, smooth.
Other presses: the oil pressure lubrication piping of press adopts Φ 6.
