Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
8 strands of Lang lay rope pre-deformation devices of one kind of the invention, as shown in Figure 1, including main shaft 3, on main shaft 3 successively
Terminal pad 1, shroud 7, mid-game 6 and hub disk 5 are installed, one end of close terminal pad 1 is connected with equipment connecting tube 23 on main shaft 3.
As shown in Fig. 2, shroud 7 radially offers multiple roller slots 16, internal layer stock roller is separately installed in roller slot 16
Wheel 11, outer layer strand roller 12 and filling stock roller 13, the position of roller slot 16 can guarantee internal layer stock roller 11, outer layer strand roller 12
It is located on different distribution circles with filling stock roller 13, makes placement position phase of distribution of the stock when passing through roller with stock in rope
Together, 7 side of shroud is connected with roller baffle 14.
As shown in figure 3, mid-game 6 is circumferentially uniformly connected with multiple drafts thread plates 19, multiple drafts thread plates 19
It is threaded with drafts adjusting screw rod 18,18 end of drafts adjusting screw rod is respectively connected with roller frame.
Roller frame includes internal layer stock roller frame 20, outer layer strand roller frame 21 and filling stock roller frame 22, internal layer stock roller frame
Internal layer stock roller 11 is installed in 20, outer layer strand roller 12, peace in filling stock roller frame 22 are installed in outer layer strand roller frame 21
Equipped with filling stock roller 13.
Shroud 7 is identical as the structure of hub disk 5.
It is connect as shown in figure 4, seam allowance 24 is assembled by pre-former in 23 one end of equipment connecting tube with terminal pad 1, equipment connects
23 other end of adapter tube assembles seam allowance 17 by equipment and connect with crank closer, and 23 side of equipment connecting tube offers peep hole 10, if
