Abstract
The utility model discloses an improved conical retaining frame forming convex-concave die which comprises a convex-concave die body. A retaining frame forming guiding arc is arranged at the lower part of the convex-concave die body; a guiding arc chord is arranged on the guiding arc; and connecting lines at the middle points of the guiding arc chord and the guiding arc are vertical to the guiding arc chord. In the designing and the manufacturing process of the retaining frame forming convex-concave die, the problems of belling and ruffle occurring during the forming process of a retaining frame can be prevented as long as the connecting lines at the middle points of the guiding arc chord and the guiding arc on the retaining frame forming guiding arc are vertical to the guiding arc chord.
Description
Technical field
The utility model relates to a kind of conical bearing retainer, especially relates to a kind of improved circular cone retainer moulding punch-die.
Background technology
At present, " mouth rises " or " fold " phenomenon on the Production of bearing, in the retainer forming process, often occur, cause a large amount of waste products.Through actual observation and thinking, the reason that this phenomenon occurs, be because the interior inclined-plane of molding concave die end points is unreasonable with the crossing design of end points of pull and stretch guiding circular arc R, the position, point of contact is if after the moulding of " groove " retainer just " rise mouthful ", if " boss " just " fold ", improve yield rate, just must address this problem.
Summary of the invention
The purpose of this utility model is exactly the problem that exists in the existing retainer forming process, a kind of improved retainer moulding punch-die is provided, it preferably resolves in the retainer forming process problem that occurs " mouth rises " and " gauffer " easily, has improved the retainer yield rate.
The purpose of this utility model is achieved through the following technical solutions, this retainer moulding punch-die comprises the convex-concave die body, described convex-concave die body bottom is a retainer moulding pilot arc, described pilot arc is provided with the pilot arc string, and described pilot arc string mid point is vertical with the pilot arc string with the line of pilot arc mid point.
In the manufacturing and designing of retainer moulding punch-die, as long as accomplish that the pilot arc string mid point on the retainer moulding pilot arc is vertical with the pilot arc string with the line of pilot arc mid point, just can prevent " mouth rises " and the problem of " gauffer " that occur in the retainer forming process.
The beneficial effects of the utility model: simple in structure, easy to manufacture, preferably resolve " mouth rises " and the problem of " gauffer " that occur in the retainer forming process.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is a schematic diagram of the present utility model
Among the figure: 1, convex-concave die body 2, retainer moulding pilot arc 3, pilot arc mid point 4, pilot arc string 5, pilot arc string mid point
The specific embodiment
As shown in Figure 1, this retainer moulding punch-die comprises convex-concave die body 1, and convex-concave die body 1 bottom is a retainer moulding pilot arc 2, and pilot arc 2 is provided with pilot arc string 4, and pilot arc string mid point 5 is vertical with pilot arc string 4 with the line of pilot arc mid point 3.In the manufacturing and designing of retainer moulding punch-die, as long as accomplish that the pilot arc string mid point 5 on the retainer moulding pilot arc 2 is vertical with pilot arc string 4 with the line of pilot arc mid point 3, just can prevent " mouth rises " and the problem of " gauffer " that occur in the retainer forming process.
