Description
Technical field
The present invention relates to a kind of device for aluminium sheet processing threaded connection pre-manufactured hole, more particularly to a kind of aluminium sheet long column
Hole tools.
Background technology
In aluminium sheet machining, it is often required to process hole on aluminium sheet, then processing screw thread in hole position is used for structural member
Contiguous block, the firmness of connection depends on hole thread quality, and the nose end mouth that prior art processes easily ftractures, screw thread process
Length is short, and connection reliability is low, and these problems still solve up for technology.
The content of the invention
In order to solve the above problems, the invention provides a kind of long post holes tools of aluminium sheet, it is characterised in that including upper
Briquetting, lower cushion block, upper plunger, lower push rod, upper holder block and/or lower lock block are connected with pressure drive division, on upper holder block and lower cushion block
Relative coaxial isometrical upper punching and lower apical pore are respectively equipped with, lower push rod coordinates with lower apical pore gap, and lower push rod upper end is set
Have and be connected with annular boss, the upper plunger energy of the upper and lower both sides of annular boss with above lower cushion block one flat end face, upper plunger middle part
Enough to coordinate respectively with upper punch clearance, upper plunger lower surface is provided with to be provided with by the depression of the inside gradual steepening in edge, Depression Centers
Downward taper spine, upper plunger upper surface edge are provided with ring-shaped platform, and frustum, the connection of frustum front end are provided with the middle part of annular boss
There is a conehead, conehead cone angle is less than the cone angle of frustum.
Further, the conehead cone angle is more than 120 degree.
Further, the upper plunger, be respectively equipped with spacing preiection on lower push rod.
The present invention is in use, pressure drive division force clamps aluminium sheet using upper holder block lower lock block, and then lower push rod is the bottom of by
Top contacts to upper surface with aluminium sheet in portion, and then upper plunger lower end is to extruding, and periphery forms annular thinning area, at medial recess
Gather, and concave point is formed at tapered centre spine, then lower push rod is descending forms a undershoot space in lower apical pore, in upset
Jumper bar conehead alignment concave point pushes up downwards middle part and swelled, and edge thinning area bending, middle part ridge extrudes to surrounding again, can be with
The longer hole in an axial direction is formed, makes screw thread effective length length, so obtained nose end head is not easy to crack, available for highly reliable
Structure connects.
Brief description of the drawings
Fig. 1 is schematic cross-sectional view of the embodiment of the present invention.
Fig. 2 is decomposing schematic representation of the embodiment of the present invention.
Reference:1 upper holder block；2 lower cushion blocks；3 upper plungeres；4 lower push rods；Punching on 5；6 times apical pores；7 end faces；8 annulars
Boss；9 depressions；10 taper spines；11 ring-shaped platforms；12 frustums；13 coneheads.
Embodiment
As shown in Figure 1, 2, the long post holes tools of the aluminium sheet are provided with upper holder block 1, lower cushion block 2, upper punching to the embodiment of the present invention
Bar 3, lower push rod 4, upper holder block and/or lower lock block are connected with pressure drive division, and aluminium sheet, upper holder block and lower cushion block are clamped for pressing
On be respectively equipped with relative coaxial isometrical upper punching 5 and lower apical pore 6, lower push rod coordinates with lower apical pore gap, on lower push rod
End be provided with above lower cushion block one flat end face 7, annular boss 8 is connected with the middle part of upper plunger, for the punching press that exerts a force, annular boss
The upper plunger of upper and lower both sides can coordinate with upper punch clearance respectively, and upper plunger lower surface is provided with by the inside gradual steepening in edge
Depression 9, Depression Centers are provided with downward taper spine 10, and upper plunger upper surface edge is provided with ring-shaped platform 11, in annular boss
Portion is provided with frustum 12, and frustum front end is connected with a conehead 13, and conehead cone angle is less than the cone angle of frustum, and conehead cone angle is more than 102
Ten degree.According to thickness of slab and the volume for pushing size design depressed part space the volume can be made identical with undershoot aluminum volume, into
Type is more preferable fuller.
The present invention is in use, pressure drive division force clamps aluminium sheet using upper holder block lower lock block, and then lower push rod is the bottom of by
Top contacts to upper surface with aluminium sheet in portion, and then upper plunger lower end is to extruding, and periphery forms annular thinning area, at medial recess
Gather, and concave point is formed at tapered centre spine, then lower push rod is descending forms a undershoot space in lower apical pore, in upset
Jumper bar conehead alignment concave point pushes up downwards middle part and swelled, and edge thinning area bending, middle part ridge extrudes to surrounding again, can be with
The longer hole in an axial direction is formed, makes screw thread effective length length, so obtained nose end head is not easy to crack, available for highly reliable
Structure connects.
During implementation, spacing preiection is respectively equipped with upper plunger, lower push rod, for limiting stroke depth, its driving can be used
Hydraulic pressure or crank driving or hammering manually；Lower push rod is connected with pressure exerting arrangement, can be that elastic component can also be hydraulic part, be used for
Upward force is provided when descending, aluminium sheet is thinned.
It is only present pre-ferred embodiments in summary, all equivalent modification done according to the application and prior art additions are equal
It is considered as the technology of the present invention category.
