Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
As shown in Figure 1 to 4, a kind of copper pipe pipe reduction device inside sets guiding comprising housing 1, the collet 2 that rises, draw pressure head 3
101 left end of step of the housing 1 in hole 104 sets guide sleeve 102, and 104 right end of pilot hole sets abducent internal taper hole 103,
The small end connection guideway 202 of 2 outer cone 201 of collet that rises in tensioner hole 204 is inside set, 202 left end of guideway sets outer spiral shell
Line 203, several open slots 205 that tail portion sets cushion hole 206, which are evenly distributed with, is separated into several fritters, the pressure of draw pressure head 3 outer cone 201
Head 301 right end of main body sets connection screw thread 302, sets opening draw hole 303 to the left in crimp body 301, in the draw hole 303
Wall is evenly distributed with straight grain indent 307, and the carry out draw that the utility model can be quick and easy and synchronous generation straight grain 1 effectively solve
The draw problem of one belled position of copper pipe.
