Sui the turn of the pressure roller, molding pressure continuouslyReduce, take off the ball into the state until the take off the ball.Pressure ball into the unit and positive question1.1 pressure ball units into:1.2 A pressure machine toTo pressure machine by sliding control motor power source as the pulley reducer, coupling material feeding spiral composition, through the material feeding spiral to materials and forced to after pressing to pressure the ball machine for material, make the material of the stability has enough material for pressure, this is a very important high pressure ball ring.In order to adapt to different compression ratio of material molding, to pressure machine spiral speed is adjustable high speed, feed for increased, to increase the pressure, and for reducing the feed, to pressure is small, due to the sliding of the motor speed constant torque the sex, work for transfer to feed is equal to the amount to pressure the ball machine, can keep constant pressure for material, make the ball billet quality is stable.A but because for shoes too big when, spiral resistance must increase, spiral speed continuous reduction, sometimes form jam phenomenon, the motor ticking over, also not burn out motor, to pressure machine speed can adopt manual speed.2 pressure ball host machine2.1 pressure ball units into:黃河科技學(xué)院畢業(yè)設(shè)計(jì)論文(英語(yǔ)文獻(xiàn)) 第 3 頁(yè) 2.1.1 to pressure machineTo pressure machine by sliding control motor power source as the pulley reducer, coupling material feeding spiral composition, through the material feeding spiral to materials and forced to after pressing to pressure the ball machine for material, make the material of the stability has enough material for pressure, this is a very important high pressure ball ring.In order to adapt to different compression ratio of material molding, to pressure machine spiral speed is adjustable high speed, feed for increased, to increase the pressure, and for reducing the feed, to pressure is small, due to the sliding of the motor speed constant torque the sex, work for transfer to feed is equal to the amount to pressure the ball machine, can keep constant pressure for material, make the ball billet quality is stable.A but because for shoes too big when, spiral resistance must increase, spiral speed continuous reduction, sometimes form jam phenomenon, the motor ticking over, also not burn out motor, to pressure machine speed can adopt manual speed2.1.2. Pressure ball host machineThe pressure ball machine adopts the single transmissionMotor (1) y250m ?-4; Power by level 55 kn belt slow down, the level 3 reducer (2) zs165, out by the great pin shaft coupling (3) spread to roll towards the spindle, the two pressure roller synchronization open gear guarantee by the second pressure roller by oil cylinder bearing spindle, overload the shaft can slip, without losing synchronization.3 dribbling machineThis dribbling machine is a common belt conveyor, main purpose is to suppress the ball out of the billet has good cake, so that realize and process of the connection, and the gap because is small, so not broken bad casting ball4 hydraulic stationInto the ball the stand or fall of quality, in addition to the size of the unit to pressure, but also is scheduled to suppress process always constant pressure, therefore in the design of hydraulic support institutions voltage, hydraulic system graph (3) the 黃河科技學(xué)院畢業(yè)設(shè)計(jì)論文(英語(yǔ)文獻(xiàn)) 第 4 頁(yè) installation drawing see chart "9" hydraulic system's main function is to provide a stable pressure roller total pressure, but a large materials into pressure roller, two roller center line suddenly increased The oil cylinder oil into the accumulator, and the total pressure change is not big, act as a security role, other through hydraulic table instructions can judge the value of the size of the total pressure, more intuitive5 to pressure machine speedAs mentioned previously, due to a variety of material of different compression ratio, the requirement to pressure machine has the performance of the variable for material, to ensure enough material feeding pressure for should be equal to the feed is still a little greater than the pressure of the ball machine requirements, in the work, if for shoes too big when, to pressure machine load overload, might form a jam phenomenon, at the same time host motor will overload, The feed for a hour can't pressure machine pressure the ball out of the density of the larger ball billet, so the pressure to pressure the ball machine machine must have speed possible, this design USES the two kinds of speed regulation methodsTo the compressor of the speed adjustment is essentially turn sent clutch motor excitation currentFor manual adjustment speaking, is operating workers in the machine operation in the radioAdjust the knob speed controller, make its growth to slow down, adjust the amount of complete by operating workers according to the billet quality stand or fall, ball pressure machine noise on the adjustment,.Because the feed for how many immediate influence the main motor (1) the size of the load, the reaction in the motor is the size of the current variation as a reset signal, poor motor stator current excitation control Poor motor stator current speed regulation and achieve excitation adjust the amount of material feeding purpose, the main motor working current increases, the instructions to pressure spiral high speed, should make turn sent the motor speed is reduced, so that the main motor work stable current in a numerical range way of different materials can be given the different work current value.黃河科技學(xué)院畢業(yè)設(shè)計(jì)論文(英語(yǔ)文獻(xiàn)) 第 5 頁(yè) 5.1 inflatable method(1) JinYou mouth slightly and the battery, the volume of 1/10 night into the shell oil pressure, so that the lubrication and then taking off filling the air valve protection, mount with pressure gauge of the air tools, and with nitrogen gas bottle through(2) the operating personnel standing in filling the air valve profile, use when tools slowly open the nitrogen bottles of switch, to move air tools improvement the handwheel, be sure to slowly open filling valve to slow the nitrogen filling, until the bacteria valves closed, slowly swell skin(3) continue to be filled with dry nitrogen, until the charge pressure of.(4) when charging the pressure required (see air tool of the gauge pressure) should stop for a few minutes until the temperature to stabilize, observe the air pressure, such as has amounted to pressure required, the air was completed.(5) charging, the inverse spiral inflatable tools the handwheel, make the filling air valve closed, shut down nitrogen bottles of switch, open air tools on air plug, will in pipeline gas off and remove inflatable tools.(6) check whether after a flat, firmly installed filling the air valve protection5.2 the charge pressure sure:Air pressure generally lower than the minimum work pressure hydraulic system of 90%, usually take 60-85%, but may not be less than 25% of the highest working pressure, because the market to sell on the bottle of of the maximum of nitrogen only $13.5 MPa So when the requirements of the air pressure than the maximum pressure nitrogen bottles, it must use the supercharger for air, about the accumulator problems such as the use of loading and unloading see the material.5.2.1 relief valve pressure relief valve relay of the adjustment for problems:According to the experiment, originally the ball of the machine work have 18.5 MPa pressure already used quite, only individual situation should be the most suitable work improve hydraulic pressure value still must according to different raw material properties determine by experiment, reason is tentatively set for 18.5 MPa work pressure(1) the relief valve adjustment for pressure is 18.5 kMPa 黃河科技學(xué)院畢業(yè)設(shè)計(jì)論文(英語(yǔ)文獻(xiàn)) 第 6 頁(yè) （2) the first pressure relay action the concentration is 18 MPa(2) first pressure(3) the relief valve adjustment for the pressure may be the setting in 190 MPSo after adjustment for oil pressure, hydraulic pressure system of 18 MPa pressure when the first relay action, ready for the next step, when the pressure to achieve 190 MPa, Relief valve begin to overflow, the oil cylinder by the relief valve to fuel tank, and at the same time, the second pressure relay action, the oil pump motor power to stop working.If the big materials into pressure roller, forcing oil cylinder piston rapidly turn back, form a larger hydraulic shocks, such as hydraulic more than 190 MPa, unloading at this time the relief valve act as a security role.Because the oil leakage, a but hydraulic down to 180 MPa the following, the first pressure relay action make oil pump start-up shocks, such as hydraulic more than 190 MPa, unloading at this time the relief valve act as a security role. Fuel supply to the hydraulic system6. Pressure roller clearance of the resetPressure machine running ball, before oil cylinder roller compaction two, at this time, pressure roller clearance between equal to zero, in order to measure the pressure roller line of the two parallel sex can be used, Crowded wire of the methods to determine, pressure roller clearance generally can be adjusted as for 2 mm or so, clearance adjustment shall first unloading the oil cylinder, and then turn reset screws, will Dou iron up top mobile force bearing move a, distance to meet requirements value will reset with nuts screw fastening7. Slot registration institutionTwo pressure roller ball skin should be but the ball processing has considered the ball groove contrapuntal problemBut because of the error processing, and the increase of the pressure roller clearance, the synchronous gear and after, the ball groove can't accurate registration, the registration institution be ball groove to registration Adjust before gear and shaft for 黃河科技學(xué)院畢業(yè)設(shè)計(jì)論文(英語(yǔ)文獻(xiàn)) 第 7 頁(yè) synchronous tight, to make it can't turn, and then turn the screw is 3 make reset piece of 4 and sliding gears piece of produce a machine to the corner, until the ball groove of accurate registration, the face in the reset after screw lock, reset before he finished.. 7.1 pressure ball mechanism made installation instructions(1) pressure of machine cover ball machine, welding machine wait for important should comply with the heavy machinery industry standard of welding current technology conditions of the regulations.(2) mechanical processing another piece should comply with the heavy machinery industry standard mechanical processing general technology conditions of the regulations.(3) Pressure of the machine assembly except special ball requirements outside, machine assembly should comply with the heavy machinery industry standard of general assembly technology requirements7.2 pressure of paint requirements ball machine:(1) for the already painted outsourcing installation without painted.(2) all installation face, face, hair LAN bolt, orientation Angle are not wait for paint(3) all welding, castings, forgings non-work smooth all the besmear green paint.(4) for exposed did not add the fast turning into protection as another piece spear compressor's pulley host should besmear pulley red paint.(5) oil cup, hydraulic pressure system on the cover with paint also red.(6) the hydraulic system of hydraulic pipe coated yellow paint, return pipe, oil absorption deep twist it yellow paint.(7) the tank with oil paint internal resistance.(8) casting, casting must first play ode child, and then in the coat of paint.(9) paint the preparing work before, paint job should press paint.
