Abstract
A kind of compressing stamping die of powdered metal liner is the utility model is related to, including former, die sleeve, formpiston and floating pressure head device, formpiston are fixed on floating pressure head device, formpiston bottom is cone, and it is corresponding with the conical cavity of former.During work, former is pushed into correct position by cylinder, and metal dust is placed in former, formpiston drops to when being contacted with metal dust, and former is uniformly distributed metal dust with base rotation, subsequent compacted metal powder and pressurize, formpiston is removed, exits cavity liner, completes a pressing process.The utility model is simple in construction, reasonable in design, and small volume is in light weight, considerably reduces manufacturing cost, while float top board makes in pressing process powder distribution evenly, it is compressing after the wall thickness of cavity liner, Density Distribution it is uniform, perforation wears deep efficiency high.
Description
Technical field：
The utility model technology is related to a kind of tools of cavity liner, is related specifically to a kind of high desnity metal powder medicine
The compressing stamping die of type cover.
Background technology：
The effect of perforating bullet is to open the underground closing sleeve pipe of oil-gas Layer, cement sheath and go deep into oil-gas Layer, establish pit shaft with
The passage of oil gas interlayer connection.Cavity liner is the critical component of perforating bullet, is known as the good reputation of perforating bullet " heart ".Wherein powder medicine
Type cover because solve that closely knit cover production efficiency is not high, machining accuracy is low and jet bit drilling after the major defect such as pestle is stifled, and turn into
The Main way of cavity liner development at present.Restricted by current Powder Liner technique, the Powder Liner of production has wall thickness
Poor big, Density Distribution problem of non-uniform, final perforation is caused to be worn deep relatively low.
The content of the invention：
The purpose of this utility model is to provide a kind of compressing stamping die of Powder Liner, is revolved in punch-pin compacting with cavity plate
Turn in the spinning process of progress simultaneously, it is ensured that the flowing of metal dust in a mold, simulating hand operation, ensure that metal dust exists
Uniformity after rotation, product density is identical after reaching shaping, and it is high that perforating bullet product wears deep index.
The utility model is adopted the technical scheme that to solve the above problems：A kind of powdered metal liner is compressing
Stamping die, including former, die sleeve, formpiston and floating pressure head device；Stepped bore is provided with die sleeve, the bottom of stepped bore is circle
Cylindricality slides chamber, and the sliding intracavitary of cylinder is provided with former, and the upper hole of stepped bore can accommodate metal dust；Formpiston is fixedly mounted on floating
On dynamic head device, formpiston bottom is cone, and it is corresponding with the conical cavity of former；Floating pressure head device includes pressure
Head, float top board, spring, gland, sliding block, centre bore is provided with pressure head bottom, is a cylinder at the top of formpiston, spring is set in
On the cylinder, through float top board, in centrally disposed hole, sliding shoe is fixed on the lateral surface of pressure head, with float top board
The sliding groove set on medial surface is slidably matched, and gland limits position of the float top board on pressure head.
The method of work of the stamping die is：Die sleeve is fixed on workbench, and former is connected with base, and base is placed in a gas
On cylinder, former is driven to move up and down under the promotion of cylinder.Base is connected with motor simultaneously, so as to drive former to rotate.Work
When metal dust is poured into the inner chamber of former, be put into formpiston, when formpiston drop to deceleration position just started contact former in powder
When last, motor drives former to start to rotate, while formpiston continues to decline, due to metal dust the rotation of mobility and former and
Powder is set gradually to be evenly distributed along former inwall, formpiston outer wall by centrifugal force, metal dust, in the uniform mistake of metal dust
Cheng Zhong, due to the gap very little between former and formpiston, float top board small range moves up and down, and can give the stream of metal dust
Dynamic slot milling, the metal dust made being distributed in the gap of former and formpiston evenly.As formpiston declines, pressure is more next
It is bigger, Powder Liner is finally shaped to pressurize during certain pressure, extract formpiston after the completion of compacting, start cylinder by former to
Upper release, the cavity liner oral area that compacting is completed is placed on die sleeve on plane, finally take out cavity liner, former is retracted, i.e.,
Complete a pressing process.
The utility model is simple in construction, reasonable in design, and small volume is in light weight, considerably reduces manufacturing cost, makes simultaneously
Powdered metal liner powder distribution in pressing process is uniform, and the wall thickness of compressing rear cavity liner, Density Distribution are uniform, penetrate
Wear deep efficiency high in hole.

Embodiment：
The utility model is described in further detail below in conjunction with the accompanying drawings：A kind of compressing punch die of powdered metal liner
Tool, including former 1, die sleeve 2, formpiston 3 and floating pressure head device；Stepped bore is provided with die sleeve 2, the bottom of stepped bore is circle
Cylindricality slides chamber, and the sliding intracavitary of cylinder is provided with former 1, and the upper hole of stepped bore can accommodate metal dust；Formpiston 3 is fixedly mounted on
On floating pressure head device, the bottom of formpiston 3 is cone, and it is corresponding with the conical cavity of former 1；Floating pressure head device includes
Pressure head 4, float top board 5, spring 6, gland 8, sliding shoe 7, centre bore is provided with the bottom of pressure head 4, the top of formpiston 3 is a cylinder
Body, spring 6 are set on the cylinder, and through float top board 5, in centrally disposed hole, sliding shoe 7 is fixed on pressure head 4
On lateral surface, the sliding groove with being set on the inner side of float top board 5 is slidably matched, and gland 8 limits float top board 5 on pressure head 4
Position.
Method of work of the present utility model is：Die sleeve is fixed on workbench, and former 1 is connected with base, and base is placed in one
On cylinder, former 1 is driven to move up and down under the promotion of cylinder.Base is connected with motor simultaneously, so as to drive former 1 to rotate.
Metal dust is poured into the inner chamber of former 1 during work, is put into formpiston 3, has just started to contact former when formpiston 3 drops to deceleration position
During powder in 1, motor drives former 1 to start to rotate, while formpiston 3 continues to decline, due to metal dust mobility and
Former 1 rotates and powder is gradually evenly distributed along the inwall of former 1, the outer wall of formpiston 3 by centrifugal force, metal dust, in gold
During category powder is uniform, due to the gap very little between former 1 and formpiston 3, the small range of float top board 5 moves up and down,
The flowing slot milling of metal dust, the metal dust made being distributed in the gap of former 1 and formpiston 3 evenly can be given.
As formpiston 3 declines, pressure is increasing, Powder Liner is finally shaped to pressurize during certain pressure, is pulled out after the completion of compacting
Go out formpiston 3, start cylinder and release former 1 upwards, the cavity liner oral area that compacting is completed is placed on die sleeve on plane, finally
Cavity liner is taken out, former 1 is retracted, that is, completes a pressing process.
