Impact press has work steps such as shaping and turning by piercing the metal with a drill (die). In mechanical presses, the movement is transferred from an electric motor and an intermediary belt wheel to the flywheel and the crank axis, and it moves the connecting rod and striker.

The impact press machine is a machine that can shape metals in a special way or cut and pierce them. The impact press has working steps such as shaping, turning by piercing the metal with a drill (die). This type of press is one of the most common presses used in cutting, drilling and shallow forms. Impact press is also called lame press.

Main Sources of Press Energy
In general, the labor force of the press machine is provided from 4 sources, each of these sources is considered for different work and the type of machine is selected according to the type of work.
Manual presses
Mechanical presses
In this type of movement, an electric motor and an intermediary belt wheel transferred to the flywheel and crank axis move the connecting rod and striker. The said machine has an adjustable table and can go up and down on the vertical rails through the diameter screws placed under it. Also, the stroke of the press head or impactor can be increased or decreased in each press with the help of special mechanisms, crank presses are made in different forms. The flywheel and axis are located on top of the body from right to left. The tonnage of crank presses is fixed and is proportional to the size of the flywheel and the metal shear resistance of the cranks.
Hydraulic presses
This model of impact press machine works with oil or water pressure, so that by compressing water or oil to the extent that it cannot be condensed anymore, the arm of the machine is used and the desired operation is done.
Pneumatic presses
Like all other pneumatic devices, this impact press also takes its power from compressed and dense air.
How to operate
How mechanical impact press work
In this system, the clutch transfers the energy stored in the flywheel of the impact press to the crankshaft, and the braking system in the impact press stops the impact press chest (piston) in a position where the clutch is free. The course of the desired impact press can be adjusted, and for this purpose, the opening of the impact press, i.e. the distance between the chest of the impact press, must be changed. The impact press can also be moved to a single-piston impact press based on the number of pistons. In the double impact press, the piston moves, both of them go up and down together, but in the triple impact press, the other two pistons are at the bottom and they go up and down, contrary to the movement of the other two pistons, usually this type of impact press is used in more accurate pressing. have
نگهداری و سرویس دستگاه پرس ضربهای در تهران
- قبل از شروع به کار باید دستگاه پرس کاملاً روغنکاری و گریس کاری شود.
- از آنجا که فشار بیشازحد به دستگاه پرس باعث خرابی قطعات میگردد، میبایست بهاندازه قدرت و تناژ هر دستگاه پرس از آن خروجی بگیریم و فشار بیشازحد مجاز به دستگاه وارد نکنیم.
- برای جلوگیری از فشار دو برابر به دستگاه پرس توجه کنید با انجام هر ضربه، قطعه را از زیرقالب کاملاً خارج کنید و سپس قطعه بعدی را وارد قالب نمایید.
- اگر در طول روز کار با دستگاه پرس طولانی شود، نیاز است مجدداً دستگاه را روغنکاری و گریس کاری نمایید.
- در صورت بروز هرگونه صدای ناهنجار و هرگونه اختلالی نا بهجا در دستگاه پرس ضربهای، به سرعت دستگاه را خاموشکنید و به مسئول تعمیر دستگاه اطلاع دهید.
- در صورت مشاهده اختلال در کارکرد دستگاه آن را تمیز نمایید تا ایراد قطعات راحتتر شناسایی گردد.
