Description
Technical field
The present invention relates to a kind of mechanical manufacturing technology, especially a kind of punching, specifically a kind of valve body punching die.
Background technology
It is well known that the spool of all kinds of senior middle school's pressure gates is required to operate by valve rod, therefore corresponding position on valve body
A mounting hole passed through for valve rod must be processed.
Currently, such mounting hole is shaped using bore process, process time is very long, needs repeatedly to bore reaming, efficiency
It is very low, seriously constrain the raising of yield.It must be improved, and punching has efficient, high-quality advantage, for this purpose, must
Corresponding punching die must be designed to meet the needs of production, improve processing efficiency.
Invention content
The purpose of the present invention is low for efficiency present in processing in the valve rod installation on existing high and middle pressure valve valve body
The problem of, a kind of valve body punching die used suitable for punching technology of design..
The technical scheme is that：
A kind of valve body punching die, it includes punch bottom plate 1 and lower mould bottom plate 2, it is characterized in that being installed on the punch bottom plate 1
There is punch 3, punching axis fixing plate 4 is installed in lower mould bottom plate 2, one end of punching axle 5 is fixed on punching axis fixing plate 4, wears
The cantilever end of mandrel 5 cuts with a step surface 6 for placing cushion block 7；Punching axle 5 is equipped with one for punching with 3 relative position of punch
The material-dropping hole 8 that piece falls.
The material-dropping hole 8 is made of cylindrical section and taper hole section, and taper hole section is located at the lower part of cylindrical section, which is in
Up-small and down-big shape in favor of punching whereabouts.
The punching axle 5 is equipped with tungsten carbide inserts 9 with punch relative position, is provided with and falls on tungsten carbide inserts 9
Expect hole 8.
The punching axle 5 is not less than the wall thickness of valve body with a distance from 2 surface of lower mould bottom plate, the vertical plane of step surface 6 from
The distance of punching axis fixing plate 4 is not less than body length.
Beneficial effects of the present invention：
Structure of the invention is reasonable, uniform force, and service life is long.
The processing technology of the present invention improves 10 times of the processing efficiency or more of valve body mounting hole compared with conventional borehole technique.
The configuration of the present invention is simple, it is easy to operate.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of valve body punching die, it includes punch bottom plate 1 and lower mould bottom plate 2, and punching is equipped on the punch bottom plate 1
First 3（Material is Cr12MoV, quenching hardness HRC63 or more）, punching axis fixing plate 4 is installed in lower mould bottom plate 2, punching axle 5
One end is fixed on punching axis fixing plate 4, and the cantilever end of punching axle 5 cuts with a step surface 6 for placing cushion block 7, punching axle 5
Material 40Cr, quenching hardness HRC50 or more can be used, to have certain toughness, it is not easy to break；Punching axle 5 is opposite with punch 3
A material-dropping hole 8 to fall for punching is equipped at position.The punching axle 5 is not less than valve body with a distance from 2 surface of lower mould bottom plate
Wall thickness, the vertical plane of step surface 6 is not less than body length with a distance from punching axis fixing plate 4.
When it is implemented, in order to further increase operability, material-dropping hole 8 may be designed to by cylindrical section and taper hole section group
At, and taper hole section is located at the lower part of cylindrical section, taper hole section is in up-small and down-big shape in favor of the whereabouts of punching.
When it is implemented, in order to improve the service life of mold, punching axle 5 is equipped with hard alloy with punch relative position
Insert 9（Material is Cr12MoV, quenching hardness HRC62 or more）, material-dropping hole 8 is provided on tungsten carbide inserts 9, material-dropping hole 8 is sheared
For mouth piece at edge of a knife shape, diameter is 0.5-1 millimeters bigger than punch diameter.
When it is implemented, cushion block 7 can also design a small stair face, offseted, is carried out using small stair face and valve body end face
Assist axially position.
The present invention application method be：
By punch bottom plate 1 and punching machine（Mechanically or hydraulically formula）Punch be connected, lower mould bottom plate 2 is fixed on punching machine.
First, valve body is sleeved in punching axle 5, the end of valve body is made to offset with punching axis fixing plate 4, realize axially position,
Cushion block 7 is inserted at the step surface 6 of 5 end of punching axle again, makes the both ends uniform stressed of punching axle 5, prevent the stress of punching axle 5
Deformation.
Secondly, start punching machine, punch pushes, and the punching swept away enters along material-dropping hole in punching axle, and is fallen under taper hole
Bottom.
Third first takes out cushion block 7, then removes valve body, and punching is fallen to naturally in lower mould bottom plate 2.
4th, the punching of next valve body can be carried out by taking punching away.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
