Open-Bottom Drive Force Press
Open-bottom drive force press, also known as pressurizing belt or cushion press, is a kind of mechanical press currently used in modern industry. It has better rigidity than the ordinary general-purpose mechanical press, and it is suitable for stamping, bending and drawing small and medium-sized products with thin plates.
Structural features
The main structure of the open-bottom drive force press consists of main table, main cylinder and power source. The main table is supported by the main cylinder and the power source. The top of the main table is covered with a plate, and a hydro-cylinder is installed below it. The main cylinder and the procured motor drive the main driver of the press, and the main driver drives the drive shaft below it to rotate. The drive shaft can drive the crankshaft and connecting rod in turn, and the connecting rod can drive the slide. The power source can adjust the speed of the drive shaft and the overload of the press to achieve the required pressing force.
Work principle
The open-bottom drive force press works by using the force generated by the rotary motion of the drive shaft to drive the reciprocating motion of the slide, thus forming a punching and pressing force. The power reserved from the power source will drive the connecting rod to transfer a certain pressure force to the slide through the crankshaft and connecting rod mechanism. When the workpiece is installed, the slide runs back and forth to punch, press and bend the workpiece. After the punch is completed, the slide is reset to the upper dead point to complete a punching cycle.
Advantages
1. Open bottom drive press has good structural material selection and reasonable design, which makes the punch more stable and reliable.
2. Open bottom drive press has good dynamic performance and sufficient power output, which make the pressing force more accurate.
3. The main parts of open bottom drive press have a long service life and the possible maintenance costs are low.
4. With reasonable configuration, the open-bottom drive press can effectively reduce the requirements for the installation environment.
5. The open bottom drive force press is equipped with a reasonable safety protection device to ensure the safety of operators.
Disadvantages
1. The noise of open-bottom drive force press is relatively large and the working environment is relatively bad.
2. The open-bottom drive force press consumes more energy than other kinds of presses.
3. As there are many parts in the open-bottom drive force press, more maintenance costs will be incurred.
4. The open bottom drive force press can only meet the requirements of one-time punching and its flexibility is not high.
Conclusion
Open-bottom drive force press is a kind of mechanical press currently used in many countries. With its stable and reliable dynamic performance, good material selection and reasonable design, it can provide the required punching or pressing force and bring benefits to the production of enterprises. On the other hand, the open-bottom drive force press also has its own drawbacks, such as small flexibility and higher energy consumption. Therefore, when choosing, we should also consider its pros and cons and select the suitable model according to our own needs.
