Abstract
The utility model provides a little for nut perforation mold core of cold extrusion which characterized in that: it includes perforation mold core body (1), perforation mold core body (1) is including pattern drawing cone section (101) and cylinder section (102), perforation mold core body (1) lies in (101) one side end faces of pattern drawing cone section and is equipped with part design die cavity (106), and part design die cavity (106) inboard sets up the waste material and concentrates hole (104), and the waste material is equipped with perforation waste material jack catch (105) on concentrating the inner wall of hole (104), and the waste material concentrates hole (104) and waste outlet (103) to be connected. The utility model discloses including the pore wall set up perforation waste material jack catch, still concentrate hole the inside neatly arranged along the axial at the waste material after the waste material of can ensureing to perforate is cuted out, guarantee the perforation mold core effectively and can not died by the perforation waste material is stifled at equipment linkage in -process, reduce because the perforation mold core by stifled dying and frequently shut down the time of causing of maintaining extravagant and product quality is undulant, increases the half -finished qualification rate of cold -heading simultaneously, reduced the waste of repairing mould, die change time, practiced thrift manufacturing cost.
Description
Technical field
This utility model belongs to five metals spare and accessory parts technical field, is exactly specifically a kind of cold extrusion shaped primary nut perforation
Core rod.
Background technology
Various hardwares are usually used in machinery industry as processing and are installed, such as nut is exactly a kind of common
Hardware.Nut is the part for closely coupling together plant equipment, by the screw thread of inner side, equivalent specifications nuts and bolt
Just can link together.Nut be connected be easily installed, globality, without the need for packing ring, convenient disassembly, it is reusable the features such as,
It is widely used on the plant equipment of every field.
And the mechanical nut of the overwhelming majority both is from the nut forming machine in cold-heading workshop, it is pressed into similar to sleeve pipe cold-extruded
Type, the cold extrusion shaped various problems that must be also faced with shearing perforation of nut, wherein, due to nut die forming machine itself
Shorter the characteristics of, perforation waste material is commonly designed in former pass-out, but nut forming machine formpiston can not load additional power (such as
Cylinder), the pass-out power for causing perforation waste material is not very big, so that there is the risk of plug-hole.
Utility model content
The purpose of this utility model is aiming at the easy plug-hole of existing cold extrusion shaped primary nut process middle punch waste material
Technological deficiency, there is provided a kind of cold extrusion shaped primary nut perforation core rod, in inner hole wall, special perforation waste material claw, circle are set
Zhou Junbu, can well guarantee to bore a hole after waste material is sheared out and still axially neatly arrange inside waste material collection mesopore
Row, effectively ensure that perforation core rod will not be perforated waste material during equipment linkage and block, and reduce because perforation core rod is blocked
Dead and caused by frequent shutdown finishing time wastes and product quality fluctuation.Greatly increase the qualified of cold-heading semi-finished product simultaneously
Rate, reduce repair a die, the waste of mould replacing time, saved production cost.
Technical scheme
In order to realize above-mentioned technical purpose, this utility model devises a kind of cold extrusion shaped primary nut perforation core rod,
It is characterized in that：It includes perforation core rod body, and the perforation core rod body includes withdrawing pattern cone segments and shell portion, described to wear
Casement core body is located in the side end face of withdrawing pattern cone segments one and is provided with part sizing die cavity, and part stock mould intracavity side arranges waste material collection
Mesopore, the inwall of waste material collection mesopore is provided with perforation waste material claw, and waste material collection mesopore is connected with waste outlet.
Beneficial effect
A kind of cold extrusion shaped primary nut that this utility model is provided perforation core rod, in inner hole wall perforation waste material card is arranged
Pawl, circumference uniform distribution, the waste material that can guarantee well to bore a hole be sheared out after still axially inside waste material collection mesopore
Proper alignment, effectively ensures that perforation core rod will not be perforated waste material during equipment linkage and block, and reduces because piercing die
Core is blocked and the time caused by frequent shutdown finishing wastes and product quality fluctuation.Greatly increase cold-heading semi-finished product simultaneously
Qualification rate, reduce repair a die, the waste of mould replacing time, saved production cost.
Description of the drawings
Accompanying drawing 1 is the main view direction schematic diagram of this utility model embodiment.
Accompanying drawing 2 is the structural representation of this utility model embodiment.
Specific embodiment
With reference to the accompanying drawings and examples, this utility model is described further.
Embodiment
As shown in figure 1 and 2, a kind of cold extrusion shaped primary nut perforation core rod, it is characterised in that：It includes piercing die
Core body 1, the perforation core rod body 1 includes withdrawing pattern cone segments 101 and shell portion 102, and the perforation core rod body 1 is located at
Part sizing die cavity 106 is provided with the side end face of withdrawing pattern cone segments 101 1, the inner side of part sizing die cavity 106 arranges waste material collection mesopore
104, the inwall of waste material collection mesopore 104 is provided with perforation waste material claw 105, and waste material collection mesopore 104 is connected with waste outlet 103.
A kind of cold extrusion shaped primary nut that this utility model is provided perforation core rod, arranges special perforation useless in inner hole wall
Material claw, circumference uniform distribution, can guarantee well to bore a hole after waste material is sheared out remains unchanged axially in waste material collection mesopore
The inside proper alignment, effectively ensures that perforation core rod will not be perforated waste material during equipment linkage and block, and reduces because wearing
Casement core is blocked and the time caused by frequent shutdown finishing wastes and product quality fluctuation.Cold-heading half is greatly increased simultaneously
The qualification rate of finished product, reduce repair a die, the waste of mould replacing time, saved production cost.
Structure, ratio, size depicted in embodiment institute accompanying drawings etc., only to coordinate in disclosed in description
Hold, so that those skilled in the art understands and reads, be not limited to the enforceable qualificationss of this utility model, therefore not
Has technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not affecting this practicality new
Under effect that type can be generated and the purpose to be reached, all should still fall obtain and can contain in the technology contents disclosed in this utility model
In the range of lid.Meanwhile, cited such as "left", "right", " inside ", the term of " middle part " " outside " in this specification, also
Only understanding for ease of narration, and be not used to limit the enforceable scope of this utility model, its relativeness is altered or modified,
Under without essence change technology contents, when being also considered as the enforceable category of this utility model.
