Below against attached drawing, by the description of the embodiment, making to the specific implementation mode of the present invention further details of
Explanation.
As shown in Figure 1 to Figure 3, the expansion drawing device, including expansion tube 01, ejector pin 02, connecting plate 03, holding screw with
And swell fixture 05, ejector pin 02 are located at swell fixture one end, swell fixture one end equipped with ejector pin is threadingly attached to swollen
In tube expansion one end, 01 other end of expansion tube is fitted and connected by end face in being located on the waist-shaped hole of connecting plate, and holding screw passes through
It is threadedly connected on connecting plate.
Hole set takes out simplicity, is applicable to the drawing of various types of hole cover parts, either cavity class or blind chamber
Receptoroid is all suitable for, and saves production time and cost.
Holding screw is symmetrically arranged a pair, respectively holding screw I 04 and holding screw II 06, expansion tube and expansion
Screw is located between a pair of of holding screw.Specifically, holding screw I 04 and holding screw II 06 are threadingly attached to connecting plate
03 both sides.
The end of thread of expansion tube 01 is equipped with for clamped flat position；The expansion piece peripheral hardware of expansion tube there are two step surface,
Cone angle is equipped in expansion piece.
Ejector pin 02 is threadedly attached in swell fixture end；The end of ejector pin is equipped with the conical surface, the conical surface of ejector pin and expansion
Cone angle fits in piece.
03 middle part of connecting plate is equipped with waist type groove, and waist type groove width is more than the flat bit width of expansion tube, and waist type groove width is less than
The flat position periphery diameter of expansion tube.Preferably, there is waist type groove at 03 middle part of connecting plate, which is slightly larger than expansion tube 01
Flat bit width, but much smaller than expansion tube 01 flat position periphery.
Two step surfaces of the expansion piece outer rim of expansion tube are of different sizes, and major diameter step surface is for being bonded hole cover parts
End face, and the width of the step anchor ring should be less than the wall thickness of hole set, and path step periphery is for being bonded hole cover parts
