Abstract
The invention relates to a single-forging forming die of double hoops for a high-speed railway insulator. The single-forging forming die comprises an upper die assembly and a lower die assembly and is characterized in that a die holder of the lower die assembly is fixed on a lower bottom plate, a die frame is arranged in the die holder, and the a guide mechanism with an inclination is arranged between the die frame and the die holder; a die core is arranged on the die frame; and an inner die mandril is fixed in the center of the lower bottom plate, and a left mandril and a right mandril which are arranged on a jacking block are also arranged in the lower bottom plate. In the compression process, double-hoop blanks are heated and then put in the die cores, the upper bottom plate moves downwards, and the heated double-hoop blanks are subjected to single compression moulding by matching a convex die with the left die core, the right die core and the inner die mandril; in the demoulding process, the two mandrils are jacked upwards by the jacking block, the die cores move upwards along with the die frame; and when the double hoops in the die cores are separated from the inner die mandril, the upward moving edge of the die frame is opened towards two sides under the action of the guide mechanism, so that the double hoops can be demoulded and taken down. Therefore, the double-hoop single-forming forming die is capable of smoothly realizing single compression moulding, high in compression efficiency and convenient to demould; and mould clamping and mould releasing are realized by virtue of the guide mechanism, and therefore the quantity of oil cylinders is greatly reduced.
Description
Technical field
The present invention relates to a kind of mould, particularly a kind of high-speed railway insulator is with forging and molding mould of double fastener hoop.
Background technology
The double fastener hoop is used for the applied to high-speed railway touching net cantilever support, and as shown in Figure 1, it is made of large pressure contact portion a and little pressure contact portion b, and large and small pressure contact portion is tubulose, and little pressure contact portion end outer surface is provided with annular protrusion.
The mode of producing at present the double fastener hoop has two kinds: a kind of is the method that adopts casting, and its existent defect is: interior tissue is loose, and shrinkage cavity, defects i.e.cracks are arranged, and can't meet the quality requirement, and has larger potential safety hazard, and scraps more.
Can also adopt the method for forging, for example number of patent application 201110203387.7 discloses a kind of bar-shaped insulator support post molding die for high-speed railway, it comprises cope match-plate pattern and lower bolster, the cope match-plate pattern center is equipped with upper punch, and both sides are separately installed with vertical left die locking cylinder and right die locking cylinder; Die holder is installed on the lower bolster, is provided with left die, right die in the die holder, this left die and right die are driven by left side cylinder and right side cylinder respectively and move horizontally, and are fixed with respectively left and right die in the left and right die, at the die holder center lower punch are installed also; The piston rod end of described left and right die locking cylinder is taper or wedge structure, and the lateral surface of left and right die is provided with taper or the wedge structure that cooperates with left and right die locking cylinder piston rod.
During moulding, promote left and right die matched moulds by the left and right sides cylinder, after left and right die locking cylinder on the slider-actuated cope match-plate pattern and upper punch are quick descending, so that the piston rod of two die locking cylinders embeds the gap between left and right die and the die holder, utilize the piston rod of die locking cylinder to cooperate the left die of promotion, the locking of right die with left and right die taper or wedge structure, the one-shot forming of realization has improved shaping efficiency, avoid Vehicle Processing, saved material.But still there is certain problem: left and right side cylinder matched moulds need to be installed simultaneously, left and right die locking cylinder, oil cylinder quantity is many, complex structure, volume is large, and manufacturing cost is high, big energy-consuming during use.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of simple in structure, working (machining) efficiency is high and the high-speed railway insulator that is convenient in demoulding with forging and molding mould of double fastener hoop.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of high-speed railway insulator is with forging and molding mould of double fastener hoop, comprise upper die component and lower membrane module, its innovative point is: upper die component comprises upper plate, cope match-plate pattern, punch, by cope match-plate pattern punch is installed on the lower surface of upper plate; Lower membrane module comprises lower shoe, die holder, framed, core rod, internal mold push rod, push rod, jacking block, die holder is fixed on the lower shoe, and the die holder center has places framed inner chamber, left and right two madial walls of die holder are inclined-plane A, all have the T shape gathering sill that extends along inclined-plane A direction at A center, inclined-plane; Framed, comprise identical left framed and right framed of structure, framed and die holder adopt wedge structure to cooperate: the left and right framed arranged outside inclined-plane B identical with the die holder madial wall inclined-plane A gradient, be provided with T shape guide pad at inclined-plane B, T shape guide pad extends along inclined-plane B direction, and T shape guide pad embeds in the T shape gathering sill and consists of the guiding mechanism with gradient; Core rod comprises left and right core rod, left and right core rod respectively by bolt be installed in left framed and right framed on, left and right core rod can consist of the die cavity of double fastener hoop behind left and right framed matched moulds, and leaves a plug patchhole below die cavity; The internal mold push rod is fixed on the lower shoe center, also is provided with left and right push rod in lower shoe, and left and right push rod is installed on the jacking block, and left and right push rod lays respectively at left and right framed below.
The invention has the advantages that: during compacting, double fastener hoop blank is in heating is placed on core rod, and upper plate is descending, cooperates once compressing by punch with left core rod, right core rod, internal mold push rod; During the demoulding, jacking block is with the two push rods jack-up that makes progress, and core rod moves with on framed; When the double fastener hoop in the core rod is thrown off the internal mold push rod, under the effect of guiding mechanism, move the limit on the framed limit and open to both sides, can realize that the demoulding takes off the double fastener hoop.Thereby realization is once compressing smoothly, and compacting efficient is high, and is convenient in demoulding, and utilizes guiding mechanism locked mode and the demoulding, has greatly reduced oil cylinder quantity, reduces energy consumption.
