Abstract
The invention relates to a shaping method for rolling needle bearing supporting. The rectangle plat board that the width and thickness of the material is the same as the supporting needed to shape, and the length is the same as the circle length of the supporting would be laid off. The long groove used to layer rolling needle would be punched. And the supporting would be formed after enclosing and joint. The supporting manufactured by the method would sharply improve the utilization ratio of material and the manufacturing efficiency.
Description
Technical field
The present invention relates to the manufacture method of needle bearing, relate in particular to the mould-forming method of needle bearing cage.
Background technique
Needle bearing is a kind of part commonly used in the mechanical transmission, and generally it comprises inner ring, outer ring, needle roller and retainer.Wherein retainer is to make needle roller remain on a fixing position, prevents that needle roller from concentrating in together.The manufacture method of present retainer: first drum shape with square steel plate pull and stretch Cheng Shen, at the bottom of washing away then barrel, the overlap that washes away biend becomes tubular shape, goes out the elongated slot of placing needle roller one by one according to the diameter of needle roller on punch press again on the circumference of tube wall, and shaping becomes retainer again.In this way, it is many to make the retainer waste of material, and manufacturing efficiency is low, and quality is difficult for guaranteeing.
Summary of the invention
Content of the present invention has overcome deficiency of the prior art, provide a kind of simply, retainer is made mould-forming method efficiently.
In order to achieve the above object, the mould-forming method of needle bearing cage is: according to wide, material thickness, the circumference of the retainer that will be shaped, blanking becomes width identical with retainer with thickness, length is the identical rectangular flat blank of retainer circumference, on blank, go out the elongated slot of placing needle roller again, circle is round again, and solder joint promptly forms retainer.
Make retainer according to said method, can improve stock utilization greatly, the efficient of production also can improve greatly, and the slotted hole on the original circumference is gone out one by one, and changing becomes on flat board once punching and finish.Technology is simple, quality guarantees easily.
Description of drawings
Fig. 1 is the blank unfolded drawing of retainer;
Fig. 2 is the unfolded drawing of going out on the blank of retainer behind the elongated slot;
Fig. 3 is the plan view behind the retainer blank circle circle;
Fig. 4 is the plan view after the welding of retainer blank circle circle.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
At first according to wide, material thickness, the circumference of the retainer that will be shaped, blanking becomes width identical with retainer with thickness, and length is the identical rectangular flat blank 1 of retainer circumference, as shown in Figure 1.On blank 1, go out the elongated slot 2 of placing needle roller again, as shown in Figure 2.The circle circle is shaped 3 as shown in Figure 3 again.Solder joint 4 again, after removal welding slag or the fleshiness shaping, promptly form retainer, as shown in Figure 4.
Claims (3)
1, a kind of mould-forming method of needle bearing cage, it is characterized in that becoming width identical with retainer with thickness according to wide, the blanking of material thickness circumference of the retainer that will be shaped, length is the identical rectangular flat blank of retainer circumference, on blank, go out the elongated slot of placing needle roller again, circle is round again, solder joint.
2, the mould-forming method of needle bearing cage according to claim 1 is characterized in that at the circle circle shaping processing technology that makes the retainer rounding being arranged between welding process.
3, the mould-forming method of needle bearing cage according to claim 1 is characterized in that finishing process is arranged one after welding processing.
