press machine Applications
Press machine suitable for electronic, instrument, cameras, jewelry, hardware and garment, shoes and hats; For sheet, strip, coil to shear, punching, blanking, forming, bending, riveting, etc; It suitable for non-ferrous metal processing, plastic parts, etc.
press machine Feature
press machine mechanical principle:
Press driven by motor through the driving mechanism work agency, on work piece process. Transmission mechanism for the belt drive, gear retarding mechanism; Screw mechanism with working mechanism and crank connecting rod mechanism and the hydraulic cylinder.
Press divided into three classes screw press, crank press and hydraulic press. Crank press is also known as mechanical press.
Screw press with no fixed bottom dead center, the larger die forgings, can blow forming for many times, can undertake singles, even playing and inching. Force is associated with the deformation of work piece, the deformation force is small, large deformation small, such as cold hit force. In these respects, it is similar to forging hammer. But its force by rack closed, so the work is smooth, vibration is much less than forging hammer, don't need a lot of foundation.
Mechanical classification:
Shanghai Katalor Enterprise Co.,LTD produce several kinds of press machines as follows:
1. pneumatic press
Pneumatic press is controlled by the gas-liquid boosting cylinder + workbench + logic valve of the press! With pneumatic and hydraulic output! 3 kg, 7 kg of air can reach 1 ton to 100 tons of high voltage output.
2. screw press
Screw press with screw, nut as a transmission mechanism, and by the spiral transmission will be positive to the rotary motion of the flywheel to slide up and down reciprocating movement of forging machinery. When working, make the flywheel speed motor rotation in saving energy, at the same time through screw, nut, push the slider downwards. When the slide block contact artifacts, flywheel were forced to slow down to stop completely, can store the rotational kinetic energy into shock, through the slide block hit the artifacts, deformation. Make the flywheel reverse after the blow, motor, drive the slider, back to the original position. The specifications of the screw press with nominal work force.
3. crank press
Crank press is one of the most commonly used cold stamping equipment, used for cold stamping die working platform. Its structure is simple, easy to use. In the form of lathe bed structure is different, the crank press can be divided into open or closed crank press crank press; According to the number of driving connecting rod different can be divided into single point press or multipoint press; According to the sliding blocks is one or two can be divided into single action press or double action press.
Transfer press is the advanced machine equipment, the integration of the many sets of compressor and generally the conveying mechanism, press unit, the thread and line end parts. The fastest rhythm can reach more than 40 times/min, and can meet the high speed automatic production. Thrum, magnetic belt can be divided into open buttress units and cleaning, oil equipment, etc.; Conveying mechanism generally consists of feeding your arms; Press generally divided into sliding block and the slide block, undertake choosing according to different requirements, line the tail section is made up of conveyor belt.
The mechanical structure
Press in other sayings: hydraulic press, hydraulic press. The press is made up of four parts: the pressure type four column hydraulic press; Combined control cabinet; Electric heating system and thermal insulation device; Mold delivery platform. The composition adopts the integrated design, elegant style, beautiful appearance, compact structure The operation is simple and reliable, easy to maintain.
1.Four column hydraulic press
Press should have reliable structure stiffness resistance to deformation capacity, hydraulic station, pressure line setting mould lifting connection device, hydraulic station and pressure has a detachable outfit dustproof cover. Artifacts can be the direction for the length (3000) direction. Technical parameters are as follows: nominal pressure of 190 t; Table size 3000 x 750 was effectively; Pressure line movement speed is 75 ~ 100 mm/s; Maximum opening distance 550 mm (excluding the heating plate); The holding time 8 h (130 ℃) artifacts; Press the base height 0.5 ~ 0.55 m; Pressure line and flatness of the 0.2 mm; Pressure line of base pressure and average gap of 0.25 mm or less (not less than 10 points).
2. heating system
Heating system is made up of steel heating plate, heating tube, thermal insulation layer. The heating plate consists of two blocks, and press the base and the pressure line of fixed respectively press Pick up and easy to tear open outfit, the heating plate made of high quality 45 # steel conditioning treatment. Electric heating tube is placed in the heating plate and a thermocouple. Thermocouple placed fastening and reliable, easy disassembly. The heating plate technology parameters: plane size 3050 x 3050 was; Flatness 0.2 mm; Measurement point arrangement: upper 3 points; The lower 6. Stainless steel heating tube outer shell material, working voltage 220 v. Unilateral outlet, the amount as a multiple of 3. Electric heating tube, reliable and convenient to replace. Connection has a protection device. Thermal insulation layer is set in the heating plate and the base (or pressure), insulation around the heating plate has set the side panel Should choose heat insulation performance is good material, the size of the plane and the heating plate, the thickness of not less than 20 mm.
3. The control cabinet
Cabinet on the instrument panel and switch; The power switch, indicator light, voltmeter, ammeter; Press the action button and indicator light; Pressure indicating instrument; Heating switch and indicator light; Digital display temperature control instrument (accuracy + / - 1 ℃); Insulation timer, over temperature alarm; Maximum service temperature of 180 ℃; The heating rate 1.7 ℃ to 2.5 ℃ / min; Temperature non uniformity + 3 ℃, the power of heating power equilibrium; Temperature control instrument for measuring temperature corresponding regional real-time control, when all reach the set value plus or minus 3 ℃, the timers, reach the setting time, temperature controlling system can automatically by craft heating or power.
4.Mold transport rack
The bench is a structure containing the hoop above, one end connected to the machine base (removable), one end is placed on the ground (adjustable height). Carrying capacity of 3 t; High hoop on the surface and the heating plate flush; Plane dimension (2800 ~ 2900) x 750 was (or parts); Insulating plate on the press pressure and the base, in order to reduce heat loss in the process of mould heating, with aluminum or stainless steel plate and insulation materials. For ease of setting can be divided into several pieces.
