Description
Technical field
Powder and powder compacting field are the utility model is related to, is more particularly to a kind of raising compacting product compactness uniformity
Punching block.
Background technology
The use of punching block mould by powder pressing forming is very common a kind of forming method in production, it, which belongs to, is pressed into
One kind in type.Compressing base substrate moisture is low, and base substrate is fine and close, and dry contraction is small, and the geomery of product is accurate, matter
Amount is high.In addition, forming process is simple, output is big, is easy to the large-scale production of mechanization, to the flat of regular geometric shapes
Flat product is particularly suitable.
It is common, the punching block mould of complete set be divided into the base (without any action in pressing process) with backing plate, former,
Upper punch three parts form.In pressing process, practice have shown that disposably loading material in a mold, suppress, suppress vertically
Power can be consumed by frictional force between storeroom and material and mould wall, actual to successively decrease along the press power of axis, cause close to pressure
First side, compactness is big, and small away from pressure head side compactness, axial length is longer, and difference is bigger.Common solution method is to use
Two-way pressing, that is, the hydraulic press for needing to use upper and lower ends to move simultaneously, and base is changed to lower punch (in pressing process
Up move), both ends are simultaneously to intermediary press, two-way compacting.However, using the hydraulic press of two-way compacting its price often than list
Expensive 2~3 times to the hydraulic press of compacting, cost is high.Therefore a small amount of cost how is put into, compactness is suppressed on one-way press
Uniform extruded article is that we need to ponder deeply.
Utility model content
The purpose of this utility model is product when being to be directed to the product unidirectionally suppressed using punching block mould common at present
Compactness difference it is big the problem of, there is provided it is a kind of improve compacting product compactness uniformity punching block, the structure of steel die is simple, use
It is simple and convenient, it is easily operated, without to press apparatus carry out it is any it is improved under the premise of, solve and pressed in unidirectional pressing process
The problem of product compactness difference is big, reach the effect of two-way compacting.
What the technical solution of the utility model was realized in：A kind of punching block for improving compacting product compactness uniformity, bag
Upper trimming die, base, former and circular steel loop are included, described base includes cylinder base backing plate and is superimposed upon on base backing plate
Cylinder is raised, and cylinder base backing plate radius is more than cylinder convex radius；The annulus steel loop and former are enclosed on base
Outside, and former is arranged on circular steel loop top, the height of steel loop is higher than the height of base backing plate, and less than total height of base
Degree；The former is one to have certain thickness cylinder, and former bottom is connected with circular steel loop top movable, former it is interior
Footpath is identical with the cylinder projection diameter of base, and former external diameter is less than steel loop external diameter；The upper trimming die is in a diameter and former
Footpath identical cylinder, when compressing, upper trimming die connects with powder to be formed in former.
Further, the cylinder base backing plate of described base and cylinder projection are integrated molding, welding fabrication
Or socket shaping.
Further, the circular steel loop is divided into two semicircular structures, and two semicircular structures cover from both sides respectively
It is connected on base.
Compared with prior art, the beneficial effects of the utility model：(1) raising compacting product compactness of the present utility model is equal
The punching block of even property to existing one-way press without carrying out any improvement, it is not required that carries out any change to original mould
Make, it is only necessary to which it is the pressing result that can reach bidirectional press to install two steel loops additional on the basis of original base.A small amount of
Under input, realize solve the problems, such as that the product compactness difference that bidirectional press could solve is big on one-way press；(2) structure letter
Single, cost input is few, easy for installation, easily operated.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
As shown in figure 1, what the technical solution of the utility model was realized in：One kind improves compacting product compactness uniformity
Punching block, including upper trimming die 1, base 4, former 2 and circular steel loop 5, described base 4 includes cylinder base backing plate 6 and folded
The cylinder projection 7 being added on base backing plate, the radius of cylinder base backing plate 6 are more than raised 7 radiuses of cylinder；The circular steel
Ring 5 and former 2 are enclosed on the outside of base 4, and former 2 is arranged on the circular top of steel loop 5, and the height of circular steel loop 5 is higher than cylinder
The height of body base backing plate 6, and less than the total height of base 4；The former 2 has certain thickness cylinder for one, and cloudy
The bottom of mould 2 is connected with the circular top movable of steel loop 5, and the internal diameter of former 2 is identical with raised 7 diameters of the cylinder of base 4, former 2
External diameter is less than the circular external diameter of steel loop 5；The upper trimming die 1 is a diameter and the internal diameter identical cylinder of former 2, when compressing,
Upper trimming die connects with powder to be formed in former.
In the present embodiment, the cylinder base backing plate 6 of the base and cylinder projection 7 are integrated molding, welding
Shaping or socket shaping.
In the present embodiment, the circular steel loop is divided into two semicircular structures, and two semicircular structures are respectively from two
While being socketed on base, this set structure, steel loop is socketed on base and is disassembled and be easy to operate.
It is a kind of improve compacting product compactness uniformity the operation principle of punching block be：Before compressing, by what is spliced
Circular steel loop, base, former are set in together, and powder to be formed, upper trimming die and powder to be formed are then put in former
Connect.When compressing, press piston moves downward through upper trimming die and first suppressed powder 1~2 time, so close to pressure head end
Powder densification degree has reached desired value.Then by whole die flip 180 degree, by one end with steel loop and base upward,
Upper trimming die down, and two semicircle steel loop steel loops is removed, and then press piston moves still further below will be close to bottom by base
The powder of seat is suppressed 1~2 time, and so close to the powder of base end, its compactness has reached desired value.Then by article removal
.
The structure of steel die of raising compacting product compactness uniformity is simple in the present embodiment, and cost input is few, easy for installation,
It is easily operated.Without needing to carry out any improvement to existing one-way press, it is not required that carry out any change to original mould
Make, it is the pressing result that can reach bidirectional press to install two steel loops additional only on the basis of original base.In a small amount of input
Under, it is possible to solve the problems, such as that the product compactness difference that bidirectional press could solve is big on one-way press.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
