Description
Technical field
The present invention relates to one can fundamentally avoid large-scale circular cone sand making machine sand discharge gate cross ferrum thickness exceed discharge gate maximum open measure time, circular cone sand making machine pressurize cylinder shaft pin and guarantor's cylinder method to circular cone sand making machine machine casing hanger, pressurize cylinder hanger pivot pin and the caused damage of pressurize cylinder, belongs to large-scale circular cone sand making machine component assembly and manufactures field.
Background technology
At present in the design of circular cone sand making machine, the multiple stage pressurize cylinder lower end hanger being positioned at circular cone sand making machine surrounding uses carbon steel pivot pin pin joint with hanger on lower bearing bracket, pressurize cylinder upper end links together with upper spider, when circular cone sand making machine crosses ferrum (running into iron block), range several millimeters on upper spider, its discharge gate increases to several millimeters, when the thickness running into iron block exceeds discharge gate maximum discharging bore, pressurize cylinder Overstroke (is strained in machinery), owing to the mechanical strength height of carbon steel pivot pin cannot be broken, cause pivot pin by upper spider, pressurize cylinder, lower bearing bracket and hanger draw deformation or damage, for thickness is at several centimeters hanger, deformation is once drawn to be difficult to repair.
Summary of the invention
Purpose of design: keep away the weak point in many background technologies, design one can fundamentally avoid large-scale circular cone sand making machine sand discharge gate cross ferrum thickness exceed discharge gate maximum open measure time, to the circular cone sand making machine pressurize cylinder shaft pin of circular cone sand making machine machine casing hanger, pressurize cylinder hanger pivot pin and the caused damage of pressurize cylinder and guarantor's cylinder method.
Design: in order to realize above-mentioned purpose of design.1, the present invention uses gray iron to make the design of pivot pin, is one of the technical characteristic of the present invention.The purpose of do so is: due to grey cast-iron phosphorus content higher (2.7%～4.0%), and carbon mainly exists with flake graphite form, and metallographic structure is ferrite+flake graphite+pearly-lustre body heat, and therefore gray iron does not has yield strength.The application utilizes this feature of gray iron to make pivot pin just, when the discharge gate of conical sand making mechanism sand runs into the iron block beyond discharge gate maximum open footpath, pivot pin owing to using gray iron to make does not has yield strength, the pivot pin that gray iron makes can be cut off by the most contrary shearing force that therefore gray iron pivot pin is formed by pressurize cylinder lower end hanger and lower bearing bracket hanger, ensure that the hanger in the upper and lower frame of pressurize cylinder will not be pulled out of shape, it is ensured that equipment will not be damaged；Secondly because the graphite in gray iron has good greasy property, it can play hanger lubrication, reduces the frictional resistance between hanger and gray iron pivot pin.2, the axle portion hangers supporting part hoop of gray iron pivot pin have overload snap slot design, be the present invention technical characteristic two.So purpose of design is: owing to the hoop of the axle portion hangers supporting part at gray iron pivot pin has overload snap slot; the power that this annular overload snap slot portion is carried is less than other pivot pin portion; therefore when gray iron pivot pin is haled by the hanger of the pressurize cylinder lower end being positioned at inside and outside annular overload tank because of overload; gray iron pivot pin is on pressurize cylinder lower end hanger and lower bearing bracket under the shear action of hanger; its gray iron pivot pin hangers supporting part two ends annularly snap slot is pulled off; both protected equipment, be conveniently replaceable again.
Technical scheme 1: a kind of circular cone sand making machine pressurize cylinder shaft pin, the end including pivot pin and pivot pin is shaped with split pin through hole, and described pivot pin uses gray iron to make.
Technical scheme 2: a kind of guarantor's cylinder method of circular cone sand making machine pressurize cylinder shaft pin, it being positioned at hanger on the multiple stage pressurize cylinder lower end of circular cone sand making machine surrounding mate with the lower hanger grafting being positioned on lower bearing bracket and use gray iron pivot pin) rolling in pin joint and upper spider determine set and constitute sand discharge gate processed with the rolling dynamic set in lower bearing bracket, when the discharge gate of conical sand making mechanism sand runs into the iron block beyond discharge gate maximum caliber, iron block in the discharge gate being made up of upper spider and lower bearing bracket forces upper spider to move upward, lower bearing bracket moves downward formation shear action, and then the multiple stage pressurize cylinder lower end hanger that will be located in circular cone sand making machine surrounding is sheared cut-out with hanger mellow lime ferrum pivot pin on lower bearing bracket, ensure that hanger is indeformable, pressurize cylinder will not be haled damage.
The present invention is compared with background technology, and one is the most fundamentally to solve circular cone sand making machine discharging to make a slip of the tongue damage when ferrum exceedes discharging opening maximum the first transaction of a day's business stroke caused circular cone sand making machine pressurize cylinder hanger and pressurize cylinder；Two is to make the replacing of gray iron pivot pin become providing for simple replacement of of normality.
