Description

Semi-dry pressing moulder

The utility model relates to a kind of processing equipment of semidry method compression moulding, in particular for making the half-dried press-forming machine of sintering-free clay brick.This machine is applicable to that other fields such as building materials, metallurgy, chemical industry are pressed into powdery, granular or its compound the solid and hollw article of bulk, sheet or other shape.

Sintering-free clay brick is a practical technique newly developed, helps saving the energy, changes the situation of baking bricks in the field of ruining.But the present brick machine that does not still have desirable suitable production sintering-free clay brick costs an arm and a leg complicated operation, inconvenient maintenance as hydraulic press; Disk-rotating brick press adopts the single face pressurization, and adobe easily produces slabbing; The friction press press time is short, so that the adobe exhaust is insufficient, causes lamination; The chain-type brick machine is bulky, the cost height, and the sticking to mould problem is difficult for solving, and yield rate is low; Existing crank-linkage type brick machine is mainly used in compacting gas permeability material preferably, suppresses sintering-free clay brick with it, and because of briquetting pressure is low, the press time is short, is unfavorable for exhaust, is easy to generate delamination splitting, sticking to mould and snap gauge phenomenon, influences the quality of brick.

The purpose of this utility model is to overcome with above-mentioned brickmaking machine produces the existing deficiency of sintering-free clay brick, a kind of briquetting pressure height is provided, and performance is good, and price is low, in light weight, energy consumption is low, and volume is little, is convenient to move and transportation, operating maintenance is convenient, be not prone to crackle and layering, the yield rate height is particularly suitable for making the small-sized brickmaking machine of sintering-free clay brick.

Task of the present utility model realizes in the following manner: this half-dried press-forming machine is based on simple four-column type toggle, by five most of compositions.Comprise mixing mechanism, the transmission mechanism of forming by motor, decelerator, pinion shaft, pinion, gear wheel, eccentric minor axis, connecting rod base, shaft coupling, connecting rod, sliding beam and Large Gear Shaft During, the body part of forming by column, lamina tecti, workbench, pressing mold bearing and frame, the feed mechanism of forming by pole, pull bar, hopper, hopper and adjusting rod, the die arrangement of forming by cope match-plate pattern, upper bolster, cam, die shoe and lower bolster.In order to overcome mold sticking, in cope match-plate pattern and upper bolster, heater is set, the vibrating device of in die shoe, establishing, can adopt pneumatic, surge, electromagnetic exciting, eccentric block or other mode of vibration, thereby eliminate the snap gauge phenomenon.Cam in the brickmaking machine of the same type in the past only has the function that adobe is ejected, and the utility model is by the improvement to the cam work profile, make it that effect of the adobe of ejecting not only be arranged, and when the sliding beam backhaul, reach synchronously and eject, make the speed of cam jack-up counterdie identical, thereby prolonged the press time with the speed that crossbeam rises, occur with the phenomenon of eliminating adobe layering and crackle, in addition, by realizing two-sided pressurization, improved the packing and the intensity of adobe.

Heating and asbestos cord are housed in the cope match-plate pattern of the present utility model, conduit is housed on the upper bolster, the magnetic folder is connected with heating through magnetic tube.

Vibrating device in the utility model can adopt the eccentric block mode of vibration, and the two end axles output motor is fixed on the die shoe, and eccentric block is equipped with at two ends, and the counterdie roller is housed in the die shoe.

In the utility model, whole cam type surface is made up of four parts, and established angle α is 8～12 °; Lift angle β is 75～95 °; Far angle of repose γ is 60～70 °, and backhaul angle θ is 10～16 °.

The utility model has adopted the patrix heating, has vibrated stamping die, has ejected synchronously and two-sided pressurization, the actual press time has been prolonged more than one times than brick machine of the same type, adobe layering and crack problem have been solved effectively, guaranteed green strength, do not have sticking to mould and snap gauge phenomenon, yield rate is more than 90%; This body is long-pending little, in light weight, simple in structure, maintenance and installation and convenient transportation; This function consumption is low, and power of motor only is 7.5 kilowatts, is 50% of similar brickmaking machine, and this machine adaptability is strong, and the soil property compacting sintering-free clay brick applicable to different regions also can be used for the compacting of Dinas brickes, flyash brick and refractory brick.In addition, this machine low price, compared with similar products, it is nearly 50% that every machine saving is invested, and saves steel 50%.The power source of this machine can adopt diesel engine or other power.
