he rubber brick molding machine

A, 50T plate vulcanizing main technical specifications 1, nominal pressure 0.5 MN mould 2, the hot plate 500mm x 500mm specifications 3 and structural form four-post type, 2 layer 4 and the distance between the layers of 125 * 125 5, piston stroke 250mm maximum 6 and plunger 200mm diameter 7 and work 16MPa work pressure oil Eight, the highest temperature of hot plate work 200 ° c 8, each hot plate 3KW heating power FC16-10, pump CB 11 and Y802 motor 4KW – 4 Second, the paper Flat vulcanization chance for all kinds of hot pressing molding materials such as rubber and immobility thermosetting plastic moulded products etc, also applies to suppress some chips. Hot plate heating mode is the highest temperature electric heating (up to 200 ° c) and steam heating (the highest temperature 170 ° c) two kinds, the minimum mold area should be greater than the hot plate one-third of the area. Plate vulcanizing structure form for four-post type. Four-post type structure consists mainly of oil cylinder, plunger, heating plate, under the crossbar, beams, activities, platform, hydraulic system, electrical system, etc. The motivation, vulcanizing by motor through the coupling pump plunger lift and drag by automatic control. Hot plate heat: electric heating element for tubular heaters, thermal resistance temperature by electric control. Third, hydraulic system Hydraulic system consists of oil pump, oil cylinder, various hydraulic valve, pressure gauges etc, oil tank, oil, electric system consisting of various process control, with complete circular movement. Pump: supply pressure oil, make the plunger, rose, Relief valve is used to control the oil system, the largest oil pressure relief valve;, Check: one-way flow oil system, to prevent reverse flow oil system, Tubing: for oil with, The main components and devices connected transmission energy. Pressuremeter: to adjust and control system of the working pressure. Four, the operation sequence Before the machine to infuse the pure oil tank, 46 # hydraulic oil, before starting the check parts connected firmly reliable, boot. Electric heating: first close air switch, the power is connected, the power indicator, then closed heating temperature control instrument for adjusting switch to the heating temperature and heating indicator plate can begin heating. Flat heating temperature, heating indicator to set out, thermostatic indicator can now sulfide production. After the first in the mould preheating gum, flat, and the time needed to adjust to the relay of sulfide, press the start time of pump motor pump driven button, the pump, press buttons, make up the plunger, hands up positions fitting closed. When reaching vulcanization pressure gauge (pre-segregation of red needle needed to work pressure, green needle to fill pressure. Usually green needle below 1Mpa about 2Mpa - red needle) contact monometers automatically cut off power supply. Pump stop work, at the same time, the timer starts working time at the stage of sulfide products, when set at the end of the time, sulfide laid back, fitting control oil plunger decline. Open mode, the mold production cycle, so unloaded products (operating in electrical system). Five, electrical system (operating) (a) the machine adopts three-phase four-wire system power, the power supply voltage 300V50Hz into line TongXin line by 6m square meters. (2) electric heating Using carbon steel straight pipe, each power w pays each layer of hot plate, amounting to 4.8 kw 2.4 kw. Heating temperature control instrument by the temperature, temperature display to required temperature indicating value. The first best adjust below 10 degrees Celsius temperature vulcanization, stable after needed to heat, so can eliminate the phenomenon, joining mould overshoot. (3) mainframe part. Electric First, then close the power switch control meter, began warming, manual and automatic control is divided in two ways. Manual control: will be transferred to button up button manually position, press, small rapidly rising oil cylinder, work, when I travel YU3 YU2, after work, constant speed up, to stop working pressure drop, after KA5 button, according to drop off work, constant speed YU4, YU1 YU4 after a delay decline rapidly dropped to the floor, after the trip to stop work. Automatic control: will be transferred to automatic position, buttons for adjusting the exhaust counter, switch toggles exhaust value, the start button to move down rapidly rising oil cylinder, small after constant speed up to suppress, exhaust, timing, time limit, to automatically after stop working. (4) note: 1 and regularly check whether the power cord and grounding contact, whether the voltage accord with the requirement. Such as low voltage electrical components will reduce the motor and the service life of the hot plate, extension and heating time. 2 and regularly check whether the pointer temperature "zero", check whether the switch control knob to flexible rotation, low, knob on the white mark line and face the blue punctuation otherwise should re-adjust if overlap. 3 and regularly check the electrical components of contacts are loose, dust, grease and without noise. To remove or replace corresponding element, lest affect machine use effect. 4 and the hot plate shell can protect both uninstalled, prevent work when shock hazard. (6) electrical components Name and number of specifications Air QF1 switch QF2, QF3, DZA7-63, and 3, C3 C25 Ac contactor on 2510 220V 6 Among 54P relays JS11S time relay Temperature control instrument XMTA608 type 5 SB1 button SB2 LA19 2 AD11 indicator XiangQi HRB P80-1) Counter,
