Description

Three-way punch expanding die
Affiliated technical field
The present invention and a kind of mould, particularly a kind of three-way punch expanding die.
Background technology
Panel radiator threeway accessory need rise by the centre of steel pipe type for spherical when producing, the method of its production is: utilize three direction hydraulic presses and mould production, mould is made of core rod and die holder, the steel pipe that during production the centre is plugged with rubber bar is put into the die cavity of mould, utilize the vertical direction oil cylinder trip holder of hydraulic press, utilize two horizontal direction oil cylinders of hydraulic press to drive extrusion die extruding workpiece and rubber bar, extruding in the middle of the steel pipe is become sphere; Because the speed of production of hydraulic press is slower, production efficiency is not high.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of three-way punch expanding die is provided, enhance productivity.
The technical solution used in the present invention is: three-way punch expanding die is made of two direction punch dies, the type that rises shaping mould, mobile die device and clamping apparatus, two direction punch dies are connected with patrix and counterdie, the type that rises shaping mould and mobile die device are between patrix and counterdie, two direction punch dies are positioned at the top and the below of the type shaping mould that rises, the type that rises shaping mould 4 is connected with mobile die device, and mobile die device is connected with counterdie.
For the single direction punching press with punch press changes the twocouese punching press into, two direction punch dies are by the upper punch core, constitute towards core, push rod, rocking bar and back-moving spring down, the upper punch core is installed on the template of patrix, one end of push rod is connected with the template of patrix, the other end of push rod is connected with an end of rocking bar, and the other end of rocking bar is connected towards core with following, and the supporting-point of rocking bar is installed on the template of counterdie, be actively tied in the pilot hole of mobile die device base plate towards core down, towards core back-moving spring be installed down.During punch ram, the downward punching press of upper punch core, simultaneously patrix drives push rod and moves downward, and the drive rocker swing changes pressing direction, drives down towards the core punching press that makes progress, and reaches the purpose of the pressing direction that changes punch press, and the design back-moving spring makes down towards core and resets.
By the type shaping mould combination of rising of mobile die device structure and two groups, two groups of type shaping moulds that rise are used alternatingly during work, increase work efficiency.Mobile die device is designed to be made of base plate, slide plate and driving element, base plate is provided with gathering sill, slide plate is actively tied on the gathering sill, the die holder of the type that rises shaping mould is fixed in slide plate, driving element is connected with slide plate, driving element is fixed on the connecting plate of base plate, and guide plate is fixed on the support column of counterdie.During work, rubber bar is inserted the die cavity of putting into one group of type shaping mould that rises behind the steel pipe workpiece, and the steel pipe workpiece inserted the activity of slide plate on core, this group type shaping mould driven element that rises pushes station, after punch forming retreats out station, another group type shaping mould that rises is pushed into station, hockets.
For mould unloading after solving moulding takes out workpiece, the type that rises shaping mould is designed to be made of two core rods, two die holders, lead and mould unloading springs, core rod is positioned at the centre of die holder, die holder is connected with mobile die device, die holder is provided with pilot hole, lead is positioned at pilot hole, and die holder is provided with spring eye, and the mould unloading spring is positioned at the spring eye of die holder.When the type that rises shaping mould driven element pushed station, two core rods and two die holders overcame the elastic force matched moulds of mould unloading spring, and when the type that rises shaping mould driven element was pulled out station, two core rods and two die holders resetted at the elastic force effect lower open die of spring.
Two core rods and two die holders of type shaping mould are locked the state that remains on matched moulds owing to need will rise during punching press, clamping apparatus is designed to be made of guiding jam plate and reference column, the guiding jam plate is provided with locating hole, the guiding jam plate is fixed on the base plate of mobile die device, one end of reference column is fixed on the template of patrix, and the other end of reference column is actively tied in the locating hole of guiding jam plate.When the type that rises shaping mould driven element pushed the clamping apparatus station, the guiding jam plate of the clamping apparatus type shaping mould that will rise clamped, and during punching press, reference column pours the locating hole of guiding jam plate, thereby the type shaping mould that guaranteed to rise is in the matched moulds state.
The invention has the beneficial effects as follows: utilize two direction punch dies to change the single direction punching press of punch press into the twocouese punching press, utilize the clamping apparatus trip holder, utilize mobile die device to move two groups of type shaping mould alternations of rising, enhance productivity.
