Description
Technical field
The present invention relates to a kind of end reinforced shaping mould and clamping molds and reinforced bar processing device, more precisely relate to
And a kind of end reinforced shaping mould of bar connecting industry and clamping mold and reinforced bar processing device, belong to rebar connecting technology
And connection mechanical equipment manufacturing technology field.
Background technology
In the large-scale construction engineerings such as bridge, subway, nuclear power, super-high buildings, water conservancy, need to connect Ribbed Bar
It connects, and screw shell connection is a kind of mode being most widely used.Screw shell is that internal thread is processed in sleeve, with ribbing
End reinforced processing external threads, when use, link together by the engaged effect of screw thread.Currently, Ribbed Bar end
Externally threaded machining tool is divided to two kinds of straight roller bed and stripping rib lathe.
In straight rolling machine operation, screw thread process rolled thread part needs four cylindrical die rolls, cylindrical die roll to push ahead to ribbing
Screw thread is processed in end reinforced progress rolled thread, after completion of processing the rotation of cylindrical die roll negative direction exit.Such mode, due to cylindrical die roll to
It is pushed forward into until Ribbed Bar end rolled thread to certain length is stopped so that the thread head error in length processed compares
Greatly, easily lead to that connection length is short and then bonding strength is low when site operation.Further, cylindrical die roll is pushed ahead, and is easy to make
Squeeze accumulation at screw thread node at Ribbed Bar, after completion of processing the rotation of cylindrical die roll negative direction exit again so that Ribbed Bar spiral shell
One-off drawing is undergone at line node, preceding step squeezes accumulation, follow-up further to stretch, and be easy to cause Ribbed Bar at screw thread node
There is machinery to pull, bonding strength is caused to reduce.
It shells in rib machine operation, needs to peel Ribbed Bar end off crust, that is, rib is peeled off, be then re-fed into silk
Head carries out end thread processing, again extracts Ribbed Bar out after completion of processing, and screw thread process rolled thread part needs three rolled thread
Wheel.Although this operation improves the flatness on Ribbed Bar surface than straight rolling machine tooling, still fail to solve screw thread steel
End error is larger, squeeze or accumulation stretch cause internal mechanical to pull, bonding strength caused by end is not rounded is low etc. asks
Topic, and shell rib lathe there is also machining accuracies the problems such as low, labor intensity is big, processing efficiency is low.Further, since Ribbed Bar
Non-round and surface irregularity, after processing screw thread, screw thread height is uneven, is only high point connection when causing to connect with screw shell,
Rather than screw thread is all connected, this also results in bonding strength reduction.That there is also structures is single for straight roller bed, replaces processing rule
The problems such as lattice process is complicated, labor intensity is big, processing efficiency is low, machining accuracy is low.
With in bar connecting, Ribbed Bar hardness, the raising of intensity and project scale, the gradual of labor intensity add
Greatly, existing equipment gradually cannot be satisfied processing request.
