JH21 Series C-frame Fixed Bolster Press Machine

Features:

1, Double pneumatic cylinder counterbalancing the weight of the slide and upper mold,can reduce the impact and noise, so as to eliminate the clearance between the connecting rod and slide.

2,By means of the PLC and pneumatic controls, this machine can carry out various actions.

3,Through the universal selector switch, it can perform the following: 1) inching; 2)single stroke; 3)continual punching; 4)emergency stop.

4,The key components such as slide, guideway, bloster and connecting rod use high intensity castiron with resin sand structure. Comparing with clay sand structure, their surfaces have 1~2 degree improved roughness and 2~3 degree improved precision.

5,The types over 60Tons are equipped brake motor which can adjust the shut height automatically.

The special advantage ----Wet clutch

1- The wet clutch technology is from Japanese famous punching factory AIDA, and had several decades experience, gain lots of customer’s acceptance.

2- The manufacturing engineering is introduced from Japan.

3- The main parts of clutch are imported from Japanese famous brand.

4- The wet clutch is multi-plate friction, better tan Single piece of friction, have longer lifetime

5- The frictions plates were dipped oil, that can be improve the abrasion resistance, and have better affection ofheatdissipation.

6- It’s adopted closed structure, can decrease the noisy, and without dust.
