Description
Technical field
Make the uniform wall thickness of hole when the present invention relates to a kind of thin plate pore-forming techniques more particularly to a kind of thin plate into deep hole
A kind of technique.
Background technique
In machinery manufacturing technology field, in many cases, need to drill on equipment, facility or its components.It is thin
Plate is a kind of green Specific processing method for being different from traditional hole forming method at deep hole machining.It is that have using metal itself
Thermoplasticity to metal plate carry out hole machined, by the spin friction heat between no cutting drill head and plate, first at porose area material
Material carries out heating softening, reduces its resistance of deformation, and then run through pore-forming, obtained according to the difference of plate thickness and drilling tool diameter
The depth in hole is about 3-4 times of plate thickness.
Due to not improved to the wall thickness of hole in most cases at present in thin plate at deep hole process aspect,
So that the hole wall thickness processed is not of uniform size, the inconsistent of wall thickness also results in the inconsistent of internal diameter, to bring up use
The defects of performance is bad.So the present invention while material is fully used, makes workpiece available at bore region not only
Reasonable streamline distribution and good mechanical performance, finally improve the synthesis service performance of orifice.
Summary of the invention
The present invention in view of the above shortcomings of the prior art, proposes a kind of thin plate into the manufacturing process of equal wall thickness deep hole.
The manufacturing process of equal wall thickness deep hole of the invention, steps are as follows:
Step 1: the disk for being provided with conical through-hole is placed on the horizontal table of drilling machine, and guarantee the center of disk
It is directed at position with the coincidence of the center of drill bit, the T-slot of disk bottom with the T-slot of workbench, then will be justified using I-shaped piece
Disk is fixed together with workbench, thus specified position of the fixed disc in drilling.
Step 2: suitable periphery is selected to cover in the hole of the conical surface, the taper that hole set is put into disk is led to
In hole, and guarantee that the center of hole set is overlapped with the center of disk.
Step 3: sheet workpiece is fixed on defined bore position by fixture, while ensuring the pore-forming of sheet workpiece
Center, bit central, hole set center and disk center be consistent.
Step 4: start drilling machine, when drill bit is rotated down in boring procedure, pass through the rotation between no cutting drill head and plate
Frictional heat generation first carries out heating softening at porose area material, reduces its resistance of deformation, and then run through pore-forming, obtains uniform wall thickness
Hole depth be greater than plate thickness hole.
Wherein, before carrying out second step, respective aperture is selected according to the aperture size of thin plate pore-forming and bit size
Hole set.
Preferably, it is contemplated that the interaction after pore-forming between drill bit and hole set so that pore-forming wall thickness is consistent, so in order to
Guarantee that hole covers not temperature distortion, selection is 1cr25ni20si2 material, material elevated temperature strength with higher and anti-oxidant
Property, belong to Austenitic heat-resistance stainless steel.800 ° of high temperature do not aoxidize, 1020 ° of operating temperature, specified to use 1150 ° of temperature, are boring
Higher operating temperature can be born during hole, can guarantee the stability of pore forming process enough.
The beneficial effects of the present invention are: the present invention is while material is fully used, and make workpiece can at bore region
To obtain reasonable streamline distribution and good mechanical performance, the synthesis service performance of orifice is finally improved.

Specific embodiment
The manufacturing process of equal wall thickness deep hole of the invention, steps are as follows:
The first step is placed on the disk 6 for being provided with conical through-hole on the horizontal platen 1 of drilling machine, and guarantees disk 6
Center and drill bit 3 center be overlapped, the T-slot of 6 bottom of disk is directed at position with the T-slot of platen 1, then utilize
I-shaped piece 7 disk 6 and platen 1 are fixed together, thus accurate location of the fixed disc 6 in drilling.
Second step selects suitable periphery that hole set 5 is put into the conical through-hole of disk 6 in the hole set 5 of the conical surface, and
Guarantee that the center of hole set 5 is overlapped with the center of disk 6.
Sheet workpiece 4 is fixed on scheduled bore position by fixture 2 by third step, at the same ensure sheet workpiece 4 at
Hole center, the center of drill bit 3, hole cover 5 center and the center of disk 6 and are consistent.
4th step, starts drilling machine, when drill bit 3 is rotated down in boring procedure, by no cutting drill head 3 and sheet workpiece 4 it
Between spin friction heat, first carry out heating softening at porose area material, reduce its resistance of deformation, and then run through pore-forming, obtain
The hole depth of uniform wall thickness is greater than the hole of plate thickness.While material is fully used, obtain sheet workpiece 4 at bore region
Reasonable streamline distribution and good mechanical performance, finally improve the synthesis service performance of orifice.
