1d, cushion block 1e and gland 1f.The cushion block 1e and gland 1f is annular, and briquetting 1c is cylindrical shape, in the inner wall of briquetting 1c
Lower end is equipped with a circle countersinking portion c, and the internal diameter of the countersinking portion c is gradually expanded downwards.The gland 1f is logical
It crosses screw thread on its outer wall and the inner wall of Upper Die-sleeve upper end is connected, be additionally provided with and at least one pulled with hexagonal on gland 1f
The hexagon ring 1g of hand corresponding matching.
Application method：
The body processed will be needed to be put into lower die-sleeve vertically first, the stretching flare 5 of 6 lower end of body is inserted into narrow diameter section
In, 6 lower part of body fits with narrowed portion, and then 7 lower end of blast cap is inserted at body upper end opening.By the lower end cap of Upper Die-sleeve
On blast cap 7, the inner wall in tapered expansion portion is bonded with 7 outer wall of blast cap, and the inner wall of extension is bonded with the outer wall on 6 top of body.
At this moment the lower end of Upper Die-sleeve, which is also inserted into, pours into expansion section, so that it is guaranteed that body 6 is coaxial distribution with blast cap 7, at this moment due to wind
7 outer wall of cap is to the jacking in the tapered expansion portion of Upper Die-sleeve, therefore the annular table of the lower end of Upper Die-sleeve and lower die-sleeve expansion section bottom end
It is separated with certain distance between being gone back between rank.
