Description
Technical field
The utility model relates to the hot upsetting forming frock of a kind of nut, belongs to the technical field of securing member processing tool.
Background technology
The machine-shaping mode of nut has two kinds of cold-heading molding and hot upsetting moulding, and cold-heading is automated machine tool production, and production efficiency is high, but the range of work is limited, and is many to market top nut specification, and the assorted situation of material is difficult to satisfy.Hot upsetting makes the easily deformable and moulding of metal by to upsetting after the bar heating, can be applied to more flexibly the processing of various standard class and nonstandard class nut product, but can't produce by automated machine tool production, and production efficiency is low.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide that a kind of nut moulding process is simple, frock is changed the hot upsetting forming frock of nut easy and simple to handle and that production efficiency is high.
The hot upsetting forming frock of nut described in the utility model is characterized in that: comprise an order just upsetting shaped device and two order shaping hole punched devices;
One order just upsetting shaped device comprises upper die and lower die and unloading mechanism, patrix is comprised of cope match-plate pattern, punch holder and upper punch, punch holder links to each other with cope match-plate pattern, upper punch is installed on the punch holder, counterdie comprises lower bolster and lower formwork, lower bolster is fixedly connected with punch press bed body one, lower formwork is installed on the lower bolster, be provided with compacted under mould, lower hexagonal mould, counterdie cushion block and lower push rod in the lower formwork from top to bottom, the compacted under mould is corresponding with the upper punch position, and unloading mechanism is by connecting rod double-screw bolt and cope match-plate pattern interlock;
Two order shaping hole punched devices comprise patrix, counterdie and unloading mechanism, patrix is by cope match-plate pattern, punch holder and upper punch form, punch holder links to each other with cope match-plate pattern, upper punch is installed on the punch holder, the stamping rod is installed in upper punch inside, counterdie comprises lower bolster and lower formwork, lower bolster is fixedly connected with punch press bed body two, lower formwork is installed on the lower bolster, be provided with the compacted under mould from top to bottom in the lower formwork, counterdie top cylinder, counterdie thimble and lower push rod, the compacted under mould is corresponding with the upper punch position, counterdie top cylinder inner sleeve has the bottom punch rod corresponding with upper punch rod position, counterdie top cylinder is connected with lower push rod by the counterdie thimble, and unloading mechanism is by connecting rod double-screw bolt and cope match-plate pattern interlock.
Wherein:
Unloading mechanism in the first upsetting shaped device of a described order and the two order shaping hole punched devices all comprises stripper and material returned bolt, stripper is fixedly connected with cope match-plate pattern by the connecting rod double-screw bolt, material returned bolt on the stripper is corresponding with the position of lower push rod, deviates from from counterdie by the nut of unloading mechanism after with upsetting.
A described order just arranges upsetting drum device on the upsetting shaped device, and upsetting drum device is comprised of the upsetting drum patrix that is installed in the cope match-plate pattern bottom and the upsetting drum counterdie that is installed in lower bolster top, and upsetting drum patrix is mutually corresponding with the position of upsetting drum counterdie.By upsetting drum device (i.e. design upsetting drum operation before hot upsetting moulding) is set, can realize the front jumping-up initial set of just upsetting of bar, and then the bar behind the jumping-up put into the shaping mould upsetting, and reduced like this upsetting ratio of product, be conducive to the smooth moulding of postorder nut upsetting.
Operation principle and process:
(1) the jumping-up initial set before the just upsetting of bar: after round steel bar burning is red, be placed on the upsetting drum counterdie, an order just patrix of upsetting shaped device moves down, and upsetting drum patrix falls, and upsetting is roused patrix and cooperated extruding with upsetting drum counterdie, with the bar jumping-up;
Just upsetting moulding of (2) one orders: will be put into through the bar of jumping-up on the compacted under mould of the first upsetting shaped device of an order, patrix falls, upper punch presses down, bar is pressed in the compacted under mould, and afterwards, patrix lifts, stripper is raised simultaneously, material returned bolt jack-up lower push rod, counterdie cushion block, lower hexagonal mould, the nut after the most just upsetting moulding ejects from the die cavity of compacted under mould, finishes the first upsetting of nut;
(3) two order shaping punchings: the nut of first upsetting moulding is changed on the compacted under mould of two order apparatus for shaping, patrix falls, upper punch presses down, nut is pressed in the compacted under mould, iron core in the nut is upwards gone out by the bottom punch rod simultaneously, iron core is headed in the upper punch, afterwards, patrix lifts, and the upper punch rod ejects iron core in upper punch, and stripper rises simultaneously, material returned bolt make progress jack-up lower push rod, counterdie thimble, counterdie top cylinder, nut ejects from the compacted under mould the most at last, and the hot upsetting of nut is finished, and operates easy to use.
One order just arranges lower hexagonal mould in the upsetting shaped device, when upsetting opposite side processed is measure-alike but during the nut that thickness is different, need not dismantle counterdie, only needs with hexagonal under the strong magnets sucking-off, and the lower hexagonal of replacing different-thickness gets final product.This design has reduced the loaded down with trivial details, time saving and energy saving of mold exchange more.
The a described order just upper punch of upsetting shaped device is installed on the punch holder by lock sleeve.
