Abstract
A kind of tapered roller bearing ring forges anti-extruding mold, is related to a kind of anti-extruding mold of forging, including anti-crowded drift（1）With anti-material extrusion base（5）, instead squeeze drift（1）Conical end squeeze into anti-material extrusion base（5）Inner chamber in, it is anti-squeeze drift（1）The step at middle part, which is provided with, inlays disk（2）, inlay disk（2）Bottom surface and anti-material extrusion base（5）Above be in contact, inlaying disk（2）The both sides of bottom surface are equipped with the semicircle steam vent of depression（3）, in anti-material extrusion base（5）It is anti-on internal diameter above to squeeze the chamfering formed（4）With steam vent（3）Connection is set；The utility model on disk is inlayed by setting the semicircle steam vent of depression, and semicircle steam vent connect settings with the anti-chamfering formed of squeezing on anti-material extrusion base internal diameter, effectively eliminates and instead squeezes the inner chamber caused in process and be recessed, greatly reduces percent defective.
Description
Technical field
The utility model is related to a kind of anti-extruding mold of forging, more particularly, to a kind of anti-crowded mould of tapered roller bearing ring forging
Tool.
Background technology
Known, in conical bearing manufacture, forging is in important step, the inherent quality of product is decide, in circular cone
The anti-crowded process of forging, anti-crowded drift needs water cooling, and anti-material extrusion base inner chamber has water inflow when anti-crowded, but anti-crowded process needs in advance
Big step is molded, the water of anti-material extrusion base inner chamber can not be discharged after being closed at the top of anti-crowded drift with the big step of anti-material extrusion base, larger
Hydraulic pressure makes anti-material extrusion base inner chamber form depression, and through reaming process, this depression can form folding, and Vehicle Processing can not often eliminate this and lack
Fall into, very big hidden danger of quality caused to product, it is necessary to a large amount of turner reviewer and defect-detecting equipment carry out quality discrimination to product,
This measure adds product and differentiates cost, has aggravated company management cost input, have impact on company's benefit；Therefore a kind of reduction is proposed
Conical bearing manufacturing cost, rate of reducing the number of rejects and seconds, reduction product differentiate that a kind of tapered roller bearing ring of cost forges anti-extruding mold, into
For the basic demand of those skilled in the art.
The content of the invention
In order to overcome the shortcomings of in background technology, the utility model discloses a kind of anti-crowded mould of tapered roller bearing ring forging
Tool, by setting the semicircle steam vent of depression, and semicircle steam vent and anti-crowded shape on anti-material extrusion base internal diameter on disk is inlayed
Into chamfering connect and set, realize the inner chamber depression for eliminating and being caused in anti-crowded process, the purpose for rate of effectively reducing the number of rejects and seconds.
In order to realize the goal of the invention, the utility model is adopted the following technical scheme that：
A kind of tapered roller bearing ring forges anti-extruding mold, including anti-crowded drift and anti-material extrusion base, the conical end of anti-crowded drift
In the inner chamber for squeezing into anti-material extrusion base, squeezed anti-on the step in the middle part of drift provided with disk is inlayed, inlay the bottom surface of disk and anti-material extrusion base
Above be in contact, the semicircle steam vent of depression is equipped with the both sides for inlaying the face of trying to get to the heart of a matter, above anti-material extrusion base on internal diameter
The anti-chamfering formed of squeezing connects setting with steam vent.
Described tapered roller bearing ring forges anti-extruding mold, and the steam vent is through hole.
By adopting the above-described technical solution, the utility model has the advantages that：
Tapered roller bearing ring described in the utility model forges anti-extruding mold, by the semicircle that depression is set on disk is inlayed
Shape steam vent, and semicircle steam vent connects setting with the anti-chamfering formed of squeezing on anti-material extrusion base internal diameter, effectively eliminates anti-squeeze
The inner chamber depression caused in process, greatly reduces percent defective, while eliminating appearance test process, eventually reduces cone axis
The manufacturing cost held.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1st, drift is instead squeezed；2nd, disk is inlayed；3rd, steam vent；4th, chamfering；5th, anti-material extrusion base.
Embodiment
Explanation the utility model that can be detailed by the following examples, open the purpose of this utility model is intended to protection
All technological improvements in the range of the utility model.
Tapered roller bearing ring with reference to described in accompanying drawing 1 forges anti-extruding mold, including anti-crowded drift 1 and anti-material extrusion base 5, anti-to squeeze
The conical end of drift 1 is squeezed into the inner chamber of anti-material extrusion base 5, provided with disk 2 is inlayed on the anti-step for squeezing the middle part of drift 1, inlays disk 2
Bottom surface with being in contact above anti-material extrusion base 5, be equipped with the semicircle steam vent 3 of depression, institute in the both sides for inlaying the bottom surface of disk 2
Steam vent 3 is stated for through hole；The anti-chamfering 4 formed of squeezing connects setting with steam vent 3 on internal diameter above anti-material extrusion base 5.
Implement tapered roller bearing ring described in the utility model and forge anti-extruding mold, when in use, the anti-crowded top of drift 1
Conical end is squeezed into the inner chamber of anti-material extrusion base 5, forms chamfering 4 on the internal diameter of anti-material extrusion base 5, and anti-squish body is from anti-material extrusion base
Enter chamfering 4 in 5 inner chamber, discharged hence into steam vent 3, the utility model effectively eliminates what is caused in anti-crowded process
Inner chamber is recessed, and greatly reduces percent defective, eventually reduces the manufacturing cost of conical bearing.
The non-detailed portion of the utility model is prior art.
The embodiment selected herein to disclose goal of the invention of the present utility model, is presently considered to be suitable,
However, it should be understood that, the utility model is intended to include the institute of all embodiments belonged in the range of this design and utility model
Change and improve.
