JB23 punch press is a suitable open type crank press featuring a left and right open type machine body (i.e. C-shaped machine body). Its steel plate welded body has high shock-absorbing performance. Its novel overall design gives the machine elegant appearance. Its throat has certain depth. The compact structure makes the use convenient and operation safe. The punch press is equipped with a turn-key rigid clutch, a cam band brake and a press-down type safety device. Its working table is open on three sides, so the mold loading and unloading and operation are convenient. The punch press is widely used for it provides good conditions for mechanization and automation. And as main equipment for plate punching production, the punch press can be used for punching holes, blanking, trimming, bending, shallow stretching and forming in national defense, aerospace, automobile, tractor, motor, electrical appliance, bearing, instruments, agricultural machine and tool, bicycle, sewing, mechanical appliance, daily hardware and coinage departments.
The Machine of Whole structure and Characteristics:
J23 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
- 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.
- 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 beautiful.
- High accuracy, high efficiency, simple and convenient operation, good performance, favorable price and best service.
Transmission control and brake systems:
- 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
- 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.
- Electrical control is installed PLC, 8 group cam controller, reliable action.
- Electrical control adopts Omron PLC for centralized control, improved machine reliability
- Proximity switch with 8 groups consisting of Schneider cam controller, reliable synchronization detection and monitoring.
- Machine is with both hands button and foot switch to achieve continuous,single and inchingpractices.
- Can move the ram up slowly,which allows the operator to control Mold adjustment conveniently.
Ram adjustment and Structure:
- 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.
- 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:
- 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.
- Protective fence and the safety interlock to ensure the operation safety. Have a movable single-hand pedal switch,easy to operate.
