Enter raw material cabin storage, powdered lime and the communicated belt of powdery raw coal deliver to dryer, and into formation system, it is qualified to be made
Pelletizing, pelletizing are delivered to no heat carrier heat accumulation type radiant tube preheating furnace and preheated.High temperature pelletizing after heating, it is specially designed
High temperature is heat-fed to closed type calcium carbide furnace, and pelletizing gives birth to reaction generation calcium carbide, the timing of high-quality finished product calcium carbide in stove through high temperature reduction
Discharge out of the furnace, pelletizing heats in preheating furnace can also be pyrolyzed out flammable gas, and artificial petroleum can be generated after subsequent purification, conversion
And natural gas.
Without heat carrier heat accumulation type radiant tube preheating furnace operating temperature up to 800 DEG C, furnace bottom framework is considered when design
Thermal expansion, dilatation seams are left, because coal-bearing pellets in preheating furnace can be pyrolyzed out a part of flammable gas, so preheating furnace is necessary
It is hermetically sealed, avoid air from entering, therefore solve thermal expansion and sealing using the expansion joint of particular design in furnace bottom framework junction
Problem.
Preheating furnace furnace bottom expansion joint is non-standard de-sign, need to design a kind of process unit of invention to complete the expansion of preheating furnace furnace bottom
The processing and manufacturing of section.
The content of the invention：
It is an object of the present invention to overcome deficiency of the prior art, company's existing equipment is made full use of, invents a kind of preheating furnace
Furnace bottom expansion joint manufacturing process device completes the processing and manufacturing of preheating furnace furnace bottom expansion joint.This manufacturing process device advantage is
Formed product compacting is simple, and the demoulding is simple, convenient, makes precision height, and surface smoothness is high.
To achieve the above object, the present invention provides following technical scheme：A kind of preheating furnace furnace bottom expansion joint manufacturing process dress
Put, including frame, it is characterized in that the frame top is provided with hydraulic jack, frame bilateral portion is provided with guide pillar, bottom of the frame is provided with

Mold tool mechanism is installed on plate, lower mold tooling mechanism is installed on base.
Preferably, the mold tool mechanism is made up of mold base, discharging spring, discharging push rod, cavity plate, on
Mold base is fixed on pressing plate, and cavity plate and mold base are by bolt connection, and cavity plate is interior to be provided with discharging push rod, discharging push rod
Top is connected with the discharging spring in mold base.
Preferably, the lower mold tooling mechanism is made up of guide spiro rod, guide spring, punch-pin, lower mold base, under
Mold base is fixed on base, and lower mold base sidepiece is being led provided with guide spring is arranged with guide spiro rod, guide spiro rod
Punch-pin overcoat is set with to screw rod, punch-pin overcoat center is equipped with punch-pin, and punch-pin and lower mold base are by bolt connection.
Present invention assembling uses mode connects for screw entirely, avoids welding from splicing, the welding contraction distortion brought, it is swollen to influence post-production
Swollen section accuracy；Cavity plate is molded for expansion joint, and oil cylinder lifts after shaping, and expansion joint is promoted by the effect of discharging spring force and unloaded
Expect push rod, expansion joint is ejected into cavity plate, easy-unloading.Punch-pin is molded for expansion joint, and guide spiro rod and guide spring are used for
It is oriented to and buffers when mold tooling mechanism pushes.Using preheating furnace furnace bottom expansion joint manufacturing process device, precision height, the demoulding are made
Easily, surface smoothness is high, and fabrication cycle shortens, and manufacturing process is simple, be easy to human users greatly reduce cost of labor and
Cost of manufacture.
