Abstract
The utility model discloses a die for forging and installing a dissimilar metal composite piston, which comprises a protruding die (8) and a concave die, wherein the concave die is arranged on a die holder (3); the protruding die is in a cylinder structure, and the diameter of the protruding die corresponds to the dimension of a big end of a piston head (7); the concave die comprises a concave die core (1) and a concave die outer ring (2), and the concave die outer ring (2) encloses the periphery of the concave die core (1); a stepped hole which corresponds to the shape of the piston head is arranged inside the concave die core; a boss (11) is arranged at the upper end of the die holder (3) and extends into a concave die hole, and the outer diameter of the boss (11) corresponds to the dimension of a small end of the piston head; and central holes (12) which are used for accommodating a piston rod (6) and a press ejection rod (4) are arranged inside the die holder (3). The die is used when combining the dissimilar metal composite piston through the forging and installing process, so that the piston head and the piston rod of different materials are integrated as a whole through the forging and installing process.
Description
Technical field
The utility model relates to technical field of mold, is specifically related to a kind of dissimilar metal composite piston forging dress and uses mould.
Background technology
Existing high-voltage electrical apparatus piston is all processed by copper alloy, and the anti-push-and-pull intensity of the internal thread of its rod member afterbody is weak; And the material price of copper alloy exceeds 7-8 doubly than the material price of steel at present, and the twice that the tensile strength of steel is higher than copper alloy again is many.In view of above factor, for improving whole rod member of piston and tailing screw flight tension compression strength and reducing the product cost, can change piston rod portion into steel, forge dress technology be combined into the copper alloy piston head meridian.
Summary of the invention
The utility model technical problem to be solved provides a kind of dissimilar metal composite piston through forging the mould of using when dress technology combines, and the piston head of unlike material and piston rod are integral through forging dress technology.
For realizing the foregoing invention purpose, following technical scheme is adopted in the invention:
A kind of dissimilar metal composite piston is forged dress and is used mould, comprises punch and die, and die is arranged on the die holder; Punch is set to column structure, and the convex mould diameter size is corresponding to the big end size of piston head; Die comprises die plate insert and die outer ring, and die outer ring circle is located at the die plate insert periphery; Be provided with in the die plate insert and the corresponding shoulder hole of piston head shape; The die holder upper end is provided with boss, and boss puts in the die hole, and the boss outside dimension is corresponding to piston head small end size; Be provided with in the die holder in order to hold the centre bore of piston rod and forcing press push rod.
Further, when die holder is arranged on the press bench, between workbench and die holder, backing plate is set.
Further, the backing plate center drilling, the forcing press push rod passes from the hole.
Further, punch is connected with the forcing press upper table through the punch connection.
Further, die outer ring and die plate insert are interference fit.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
1, combines with existing forcing press through this grinding tool, under non-welding situation, solved the high-intensity method of attachment of dissimilar metal, make each most chief of two kinds of metals.From then on also practice thrift a large amount of copper alloys, reduced product cost.
2, this mould can be reused, and has practiced thrift the equipment input cost.
Description of drawings
Fig. 1 is the structural representation of the utility model application state.
Among the figure: 1, die plate insert; 2, die outer ring; 3, die holder; 4, push rod; 5, backing plate; 6, piston rod; 7, piston head; 8, punch; 9, punch connects; 10, shoulder hole; 11, boss; 12, centre bore.
The specific embodiment
The invention is explained further that what need explanation is that following examples are not interpreted as the restriction to the invention below in conjunction with preferred embodiment.
In conjunction with Fig. 1, the dissimilar metal composite piston is forged dress and is used mould, comprises punch 8 and die, and die is arranged on the die holder 3; Punch is set to column structure, and the convex mould diameter size is corresponding to piston head 7 big end sizes; Die comprises die plate insert 1 and die outer ring 2, and it is interference fit with die plate insert that die outer ring 2 circles are located at die plate insert 1 periphery; Be provided with in the die plate insert 1 and the corresponding shoulder hole 10 of piston head 7 shapes; Die holder 3 upper ends are provided with boss 11, and boss puts in the die hole, and the boss outside dimension is corresponding to piston head small end size; Be provided with centre bore 12 in the die holder, in order to hold piston rod 6 and forcing press push rod 4.
During use, mould is contained in respectively on the last lower table of hydraulic press, specifically to be punch 8 connect 9 through punch is connected with the forcing press upper table, concentricity is debugged get well fastening good housing screw; Die holder is arranged on the press bench, and backing plate 5 is set between workbench and die holder, and backing plate 5 center drillings are convenient to forcing press push rod 4 and are passed.
When dress is forged in extruding, there is groove one end upwards vertically to put into die in piston rod, again the copper alloy material put on the die inner steel piece piston rod, then two kinds of metals in the enforcement punch Extruding die under the process oil press; Extrusion modling is retreated oil return press drive punch and is withdrawed from die; The up promotion push rod of oil cylinder will push and forge the composite piston install and eject under the process oil press then.
This mould can be reused, and punch is not lubricated in the use, and die sprays rare graphite water.
