Abstract
The present invention provides a kind of ribbon retainer process for stamping, includes the following steps: that (1) stocks up: the plate of selection being determined billot width by the blank dimension and pattern type of technology Calculation, required billot is cut on square shears；(2) it cuts out ring: billot is punched on press machine using the composite die of blanking, punching, obtain annular blank；(3) it shapes: annular blank is stamping on press machine using shaping dies；(4) billot after forming shaping: is subjected to pocket shape spherical surface shaping using shaping mould on press machine；(5) billot after shaping punch rivet holes: is gone out into the halving hole driven the rivets on each lintel of retainer circumference using sleeving and riveting mould for nail.Present invention improves over existing process flows, solve processing problem, ensure that the precision of ribbon retainer punching, to ensure that the quality of retainer.
Description
Technical field
The present invention relates to ribbon retainer stamping technology fields, and in particular to a kind of ribbon retainer process for stamping.
Background technique
Deep groove ball bearing ribbon retainer is mainly process by sheet metal is stamped at present, is provided on retainer
Semicircle spherical surface pocket hole needs mutually to align two retainers when in use, in pocket hole place steel ball through riveting combination after with
Bearing internal external circle matches；But since the contact area in pocket hole and rolling element is big, when rotating at high speed, it may appear that noise compared with
Greatly, the higher drawback of temperature rise.
The main function of ribbon retainer punching concave die is exactly by the precision-fit with piercing punch, by retainer rivet
Hole machined molding, the problem of current processing technology is primarily present is that the small hole precision of cavity plate equal part is undesirable, center and equal part and
Hole itself required precision is all very high, its precision will directly affect the quality of retainer finished product.Due to motor cabinet and copper electrode
Requirement on machining accuracy is very high, and there is also copper electrode Expenditure Levels in process, therefore product quality not can guarantee, and also wastes
Raw material.
Influence of the Sheet Metal Forming Technology of ribbon retainer to its performance is very big, and existing Sheet Metal Forming Technology step is various, and precision
It is difficult to ensure, therefore, improves the problem of existing process flow is the art urgent need to resolve.
Summary of the invention
In view of the above shortcomings of the prior art, the present invention provides a kind of ribbon retainer process for stamping, improves existing
Process flow ensure that the quality of retainer.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of ribbon retainer process for stamping, includes the following steps:
(1) it stocks up: the plate of selection being determined into billot width by the blank dimension and pattern type of technology Calculation, at gantry
Required billot is cut on shearing machine；
(2) it cuts out ring: billot is punched on press machine using the composite die of blanking, punching, obtain annular blank；
(3) it shapes: annular blank is stamping on press machine using shaping dies；
(4) billot after forming shaping: is subjected to pocket shape spherical surface shaping using shaping mould on press machine；
(5) punch rivet holes: the billot after shaping is gone out on each lintel of retainer circumference using sleeving and riveting mould for nail and is driveed the rivets
The halving hole of nail.
Preferably, step 2, after cutting out ring, the burr altered on bucket cleaning annular blank is utilized.
Preferably, in step 4, shaping includes buffing both ends of the surface, stays 0.3~0.4mm fine grinding amount.
It preferably, further include diameter mill and plain grinding；The diameter mill and plain grinding are respectively to refine outer diameter and two with halving hole centering
End face.
The invention has the following beneficial effects: existing process flow is improved, solves processing problem, ensure that shape wave
The precision of retainer punching, to ensure that the quality of retainer.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated.
A kind of ribbon retainer process for stamping, includes the following steps:
(1) it stocks up: the plate of selection being determined into billot width by the blank dimension and pattern type of technology Calculation, at gantry
Required billot is cut on shearing machine；
(2) it cuts out ring: billot is punched on press machine using the composite die of blanking, punching, obtain annular blank；
(3) it shapes: annular blank is stamping on press machine using shaping dies；Workpiece surface must not have and split at this time
Mouth and mechanical scar；
(4) shaping: the billot after forming is subjected to pocket shape spherical surface shaping using shaping mould on press machine, so that pocket hole
Obtain the geometry and surface roughness to conform to quality requirements；
(5) punch rivet holes: the billot after shaping is gone out on each lintel of retainer circumference using sleeving and riveting mould for nail and is driveed the rivets
The halving hole of nail.
Preferably, step 2, after cutting out ring, using the burr altered on bucket cleaning annular blank, the significant burr is not had to be with workpiece
Standard.
Preferably, in step 4, shaping includes buffing both ends of the surface, stays 0.3~0.4mm fine grinding amount.
It preferably, further include diameter mill and plain grinding；The diameter mill and plain grinding are respectively to refine outer diameter and two with halving hole centering
End face.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
