Under, production cost is higher.
The content of the invention
The purpose of the present invention aims to solve the problem that existing automobile pipe fitting inefficiency, cost in pipe end processing and forming are higher and lacked
Fall into there is provided a kind of simple in construction, production efficiency is high, lower-cost automobile pipe fitting port former and its port shaping side
Method.
The present invention above-mentioned technical purpose technical scheme is that：
Automobile pipe fitting port former, including frame, mould bases, mould and top-pressure mechanism, mould bases are fixedly installed in frame
On, mould bases is provided with the mould installion chamber for installation forming mould, and mould includes corresponding upper die and lower die, drive up and down
The lift drive mechanism and core of dynamic upper mould elevating movement, lower mould are fixedly installed in the mould installion chamber by lower template
Bottom, upper mould is installed on the top of the mould installion chamber by cope plate, and lift drive mechanism is installed on the mould bases, on
Template is connected with the lift drive mechanism, is respectively arranged with the opposite face of upper die and lower die corresponding and lateral direction penetrating
Upper cavity and lower mode cavity, the finished product profile of the die cavity and automobile pipe fitting of upper cavity and lower mode cavity formation when upper die and lower die pairing
Correspondence, the core includes bulging block and multi-diameter shaft, and the path section diameter of multi-diameter shaft is less than the necking section internal diameter of automobile pipe fitting, rank
Terraced axle big footpath section diameter it is corresponding with the internal diameter of the pipe fitting body of automobile pipe fitting, bulging block be cylinder, one end of bulging block and
The end face of the big footpath section of core is fixedly connected；Described top-pressure mechanism includes being relatively arranged on the fixation at mould die cavity two ends
Jacking block and movable jacking block and driving activity jacking block fix jacking block and pass through one to the top pressure drive component of fixed jacking block relative motion
Fixed support is fixedly mounted.
Using such scheme, core is inserted in automobile pipe fitting to be formed, the path section of core is stretched out vapour to be formed
The necking section of car pipe fitting, bulging block is located in the corresponding inner chamber in formation of tubes end to be formed, then puts pipe fitting to be formed correspondence
In the lower mode cavity for putting lower mould, the upper mould of lift drive mechanism driving is moved downward until upper die and lower die pairing is so as to by automobile pipe
Part is pressed in die cavity, and fixed jacking block relies on mould one end corresponding with formation of tubes end end, and movable jacking block is leaned
In the end of multi-diameter shaft path section, top pressure drive component drives core to fixed jacking block to movable jacking block force driving activity jacking block
Motion, when bulging block top to fixation jacking block when and top pressure drive component persistently to movable jacking block and multi-diameter shaft axial force distribution, it is right
Bulging block produces extruding force, because bulging block is radially expanded for soft materials, i.e. bulging block so as to produce expansive force, to the bulging block
The tube wall of the pipe fitting of corresponding position produces certain extruding force, realizes tube wall radial direction evagination deformation forming two connection convex tendons.
It is compressed axially, is radially expanded by using the bulging block of soft materials and tube wall evagination is molded into connection convex tendon, process is simple,
Convenient mounting and clamping is quick, and production efficiency is high.
Preferably, described bulging block is polyurethane cylinder, axial projection is provided with one end end face of cylinder,
Groove corresponding with the axial projection is provided with the end face of the big footpath section of described multi-diameter shaft, when bulging block and multi-diameter shaft installation
During connection, axial projection close-fitting is plugged in groove correspondence.
