J21S mechanical Deep-throat press machine

The Machine of Whole structure and Characteristics:

J21S Series Presses is one of the new generation of plate process and developed by primapress company. ,The press is for cutting, punching, blanking, bending and light stretching work
1. C- frame provides maximum rigidity and minimum deflection for accurate parts and long tool life.Steel-welded frame, high rigidity and less deformation Compact.Thick plates and large columns provide you with the stable platform you need for your demanding application.
2. Wide body frame eliminating vibration for improved ide life and machine,which means economical and practical. Operation space is wide, and the movable bolster could be moved out of frame to set the die. The structure is simple and the appliance is also beautiful.
3. High accuracy, high efficiency, simple and convenient operation, good performance, favorable price and best service.

Transmission control and brake systems:

1. Use the combine of dry friction clutch and brake pneumatic,rigid interlocking,reliable piece of friction material semi-metallic friction material SMFM-88,less pollution, long life. With the transfer torque, rotational inertia is small, smooth transmission, flexible operation, convenient of installation and maintenance
2. Die height adjustment of slider with manual mode, the scale display. Extended by four triangular rail, easy adjustment.
3. Use double safety valve to ensure the accurate implementation of the clutch instruction.
4. Electrical control is installed PLC, 8 group cam controller, reliable action.

5. Electrical control adopts Omron PLC for centralized control, improved machine reliability
6. Proximity switch with 8 groups consisting of Schneider cam controller, reliable synchronization detection and monitoring.
7. Machine is with both hands button and foot switch to achieve continuous, single and inching practices.
8. Can move the ram up slowly,which allows the operator to control Mold adjustment conveniently.

Ram adjustment and Structure:

1. Adjustable stroke machine, slide stroke to achieve a certain level within the range of adjustable, body steel plate welded structure, the whole body is tempered, use the secondary transmission, the transmission part of the crankshaft horizontal Placement, flywheel and gear are the external open style, easy maintenance.
2. Slider is a cast box structure and rigid. Collapse of the slider-style installation of pressure overload protection device, simple structure,if the slider overload, the fuse collapse is damaged, then protect the machine tool and die from damage.

Electrical system and the safety interlock:

1. Electrical components are imported or from Sino-foreign joint Venture,in accordance with international standards,reliable safety,long life,good anti-interference ability,a radiation unit is fitted in electrical cabinet.
2. Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate.

Deep throat metal punch press Mechanical characteristics:

1. Fram : The frame is of all steel construction, fabricated from Rolled steel plates with suitable cross ribbings. Presses upto 30T will be supplied with C.I. legs. proper alignment of the frame is ensured by machining.
2. Clutch : The clutchis of pin/rolling key-type. the clutch is rigid and well supported. the clutch gives continuous strokes for mass production.
3. Crank Shaft : Crank shaft is made of special alloy steel machined to close accuracy and fitted in bronze bushes for smooth working, longer life & accuracy.
4. Flywheel : Properly sized flywheel, is made of high grade cast iron, for storing and releasing adequate energy for the pressing operations, and properly balanced for smooth running.
5. Gears : Gear are of steel cast or fabricated. Gear teeth are generated by precision hobbing machine.
Table & Ram : Table and fam are made pf high grade heavy duty cast iron & properly seasoned. They are perfectly aligned, to each other to obtain high accuracy & precision press operation.
6. Lubrication : An efficient shot luvrication system has been provided for lubricating the sliding surfaces and moving parts. The lubricant is applied by hand pump.
7. Inclining : Inclinable type presses are provided with inclining mechanism which can be easily det and locked in.
8. Mechanism : Position by spanners within minutes. the press ils so designed that even in maximum inclined position, it is stable under heavy pressing load.
