Product Description

Product Description

JH21 Series C-Type High Precision Eccentric Punching Machine                                            
The structure of the Punching Machine                                                 1.JH21 Series High Precision Presses is one of the new generation of plate process and developed by AHSC ,
The press is for cutting, punching,blanking, bending and light stretching work.

2.C-Type Steel-welded frame, high rigidity and less deformation Compact,wide body frame eliminating vibration 
for improved ide life and machine.

3.The press adopts hexahedral rectangle lengthen gib, which has high guiding precision and steady precision.

4. Highly advanced, rigidly supported gears, operate in oil bath without any noise saves space, reduces, shaft deflection,
 increases gear life.

5.High accuracy, high efficiency, simple and convenient operation, good performance, favorable price and best service.

 The clutch gives continuous strokes for mass production. 

1.The press adopts the low inertia combined dry pneumatic friction clutch and brake from easier maintenance, to ensure reliable safety and flexible action,Iow noise, long  service life.

2.Driving gear is installed into the frame and gear is immersed in oil reservoir. Customer could choose Electromagnetic  governor. which is stepless speed regulation within a certain range and enlarge the area of  craf.
3.Use adopts dual valve from TACO, Japan, which can guarantee the safety and reliability of clutch.

4.Pneumatic dual balance cylinder, which balances the slide block and punch weight to reduce noise and impact.

5.The press adopts cam controller which be combined with proximity switch which will realize the synchronous detection and monitoring reliably.

Electrical system and the safety interlock:

1.Electrical panel with cooling system designed to meet CE Standards and composed of automation and electrical equipments with SIEMENS brand.

2.Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate.

3.Machine is with both hands button and foot switch control: anti-tie down, non-repeat controls with ring guards.

4.Front Side Covers with safety switches, Back light safety guards  (Category-4),Foot pedal conforming to CE regulation.

5.Auto grease lubrication system,easy stroke adjustment mechanism increases press versatility tremendously.
