Description
Technical field
The utility model relates to mould structure, specially a kind of mould structure for realizing the two-way cold pressing of a beading.
Background technique
Diamond rope saw is widely used in exploitation and the machining and shaping of stone material as a kind of flexible cutting tool.And Buddha's warrior attendant
A stone beading are the core components of diamond rope saw, and sintering is a kind of traditional diamond wire saw bead production work after being cold-pressed
Skill.
In beading production process, needs to wrap diamantiferous metal powder material carcass in cold pressing process and matrix is cold-pressed
Together.Because the upper end of matrix is fixed by seaming chuck, and metal powder material carcass can not generate phase with matrix during suppressing a beading
To substrate motion, beading carcass is caused by the carcass of matrix upper end side to be unidirectional compacting, influence the cold moudling of a beading with most
Finished product performance.
Utility model content
To solve existing cold pressing mode when suppressing beading cold pressing base, carcass of the beading carcass by matrix upper end side is single
To compacting, the problem of cold moudling is with final products performance is influenced, the utility model proposes a kind of two-way cold pressings of a realization beading
Mould structure.
It is able to solve the mould structure of the realization two-way cold pressing of a beading of above-mentioned technical problem, technical solution includes being installed on
The seaming chuck of upper die holder bottom, except that be equipped with upper core bar in the seaming chuck, the upper end of upper core bar in upper die holder in making
With on the elastic element that can make its downward return, the lower end of the upper core bar of return is stretched out outside seaming chuck and matrix coincide, set connects,
The lower end of the concordant seaming chuck in the upper end of described matrix, the internal diameter of the outer diameter matching seaming chuck of described matrix, matrix retraction when compacting
In seaming chuck and the upper upward compression elastic element of core bar is driven, the axis rank being arranged on the upper core bar acts on upper die holder and limits
The decrement of upper core bar, axis rank acts on seaming chuck and limits the overhang of core bar when return.
Conventionally, the elastic element uses compressed spring, and the compressed spring is set in the spring base hole of upper die holder simultaneously
It pre-tightens between upper core bar and upper die holder.
It is required according to pressing process, the matrix for being 7.2mm corresponding to outer diameter, the telescopic movable amount of the upper core bar is designed as
2mm。
The utility model has the beneficial effects that
1, the utility model realizes the mould structure of the two-way cold pressing of a beading on the basis of not changing former beading cold pressing process
The two-way compacting of carcass is realized, so that the beading green density after cold pressing is uniform, is conducive to promote final products performance, and prevent
Powder enters core bar to be caused to be lost with pressure head gap.
2, the features such as the utility model has method simple, and technique is forward and compatibility is strong, at low cost.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model, the state before display matrix compacting.
Fig. 2 is state when suppressing matrix in Fig. 1 embodiment.
Figure number mark: 1, upper die holder；2, seaming chuck；3, upper core bar；4, matrix；5, compressed spring；6, axis rank.
Specific embodiment
Illustrated embodiment is described further the technical solution of the utility model with reference to the accompanying drawing.
The utility model realizes the mould structure of the two-way cold pressing of a beading, and structure includes seaming chuck 2 and upper core bar 3, in which:
The upper end of the seaming chuck 2 is fixedly installed in the bottom of upper die holder 1, and 2 inside of seaming chuck coaxially offers axle center hole,
The upper end part radial dilatation of seaming chuck 2, axle center hole herein also correspond to it is radially expanded become axial limiting hole, as shown in Figure 1, Figure 2
It is shown.
The body of rod of the upper core bar 3 is coaxially placed in the axle center hole of seaming chuck 2, corresponds to axial limiting hole, upper core bar 3
The body of rod is equipped with axis rank 6, and the axis rank 6 is limited between 1 lower end surface of upper die holder and axial limiting hole bottom hole, upper core bar 3 it is upper
Portion is extended upwardly into the spring base hole opened up inside upper die holder 1, and compressed spring 5, the compression are equipped in the spring base hole
Spring 5 pre-tightens between upper core bar 3 and upper die holder 1；Under the action of compressed spring 5, the lower end plug of upper core bar 3 is stretched out upper
The set that coincide outside pressure head 2, on the plug is connected with matrix 4, and the upper end of described matrix 4 concordant (fixing base 4 can be achieved) is in upper pressure
First 2 lower end surface and the axle center hole internal diameter of outer diameter matching 2 lower end of seaming chuck of matrix 4, as shown in Figure 1 and Figure 2.
The utility model when suppressing beading carcass, matrix 4 by lower end core bar resistance and overcome compressed spring 5 act on
Power and upwards (retraction amount acts on 1 lower end surface of upper die holder by axis rank 6 and limits) in the axle center hole of retraction seaming chuck 2 so that herein
Beading carcass and matrix 4 between generate relative motion and realize two-way compacting (beading green density after cold pressing is uniform, favorably
In promotion final products performance)；After the completion of compacting, resistance release, compressed spring 5 will by the downward return of upper core bar 3, upper core bar 3
Matrix 4 releases the lower end axle center hole of seaming chuck 2, removes the compacting powder in axle center hole, institute as shown in Figure 1, Figure 2 in push together
Show.
The matrix 4 for being 7.2mm corresponding to outer diameter, telescopic movable amount (the decrement or overhang) setting of the upper core bar 3
For 2mm.
Above embodiment is not the exhaustion of the utility model, the size of the seaming chuck 2 and upper core bar 3, upper core bar 3
Activity space (telescopic movable amount) can be cold-pressed the difference of base molding specification according to a final beading and use different sizes.
