Abstract
The utility model relates to a female and male die for a dust cover of a ball bearing. The female and male die for the dust cover of the ball bearing comprises a die head, a die holder and a locking nut. The die head and the die holder are both in a circular ring shape. The die holder is connected to the outer side of the bottom of the die head in a sleeved mode. The outer side face of the bottom of the die head is provided with a groove which is used for stitching between the die head and the die holder. The bottom of the die holder is provided with a counter bore where the locking nut is installed. The die head and the die holder are connected into a whole through the locking nut. The female and male die for the dust cover of the ball bearing has the advantages that the female and male die is of an inlaid structure, the structure is easy and convenient to machine and high in machining precision, the machined product is good in quality, the labor intensity of workers is low, the production efficiency is improved remarkably, raw materials are saved, and economic benefits are increased.
Description
Technical field
The utility model relates to a kind of ball bearing dust cap punch-die.
Background technology
Deep groove ball bearing product has two kinds of open type and encloseds, for closed bearing, need to add dust cap, and dustproof to be stamped one be steel dust cap.Dust cap mainly plays and prevents that dust from entering bearing, reducing grease and ooze out and extend the bearing effect in service life.Processing steel dust cap need to be gone out profile with mould, and in such mold, having a part is punch-die, and this punch-die difficulty of processing is large, percent defective is high, labor strength is large, and efficiency is low, difficult quality guarantee designing requirement, has a strong impact on the production of subsidiary factory.
Have point teeth such as a circle at its periphery of small column, the dust cap of going out like this can have a circle age of a draught animal accordingly, make its in the time being connected with bearing tightly riveting on bearing, prevent from dropping, play sealing effectiveness.In general processing technology, mould tooth need to be routed up with die, therefore before processing, will first make corresponding die, then be turned over the mould tooth of punch-die by pincers worker, pincers worker once can not directly be translated into shape man-hour sometimes adding, need secondary to turn over, will do like this die, waste material, loses time again, efficiency is lower, if and in turning tooth process deviation slightly, will produce waste product, percent defective is high.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of ball bearing dust cap punch-die.
The utility model solves the technical scheme that its technical problem adopts: a kind of ball bearing dust cap punch-die, comprise die head, die holder and locking nut, die head and die holder are all annular, die holder is socketed on the bottom outside of die head, the bottom outside face of die head is provided with the groove for splicing die holder, die holder bottom offers the counterbore for locking nut is installed, and die head, die holder are connected to overall structure by locking nut.
Further, the material of die head is GCr15.
Further, the material of die holder and locking nut is steel No. 45.
Further, the outer surface line cutting processing of die head has decile tooth.
The beneficial effects of the utility model are: concave-convex mold is the structure of edge body formula, and this structure processing is easy, and machining accuracy is high, the good product quality processing, and labor strength is low, and production efficiency significantly improves, and has saved raw material, has improved economic benefit.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. die head, 2. die holder, 3. locking nut.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of ball bearing dust cap punch-die as shown in Figure 1, comprise die head 1, die holder 2 and locking nut 3, die head 1 and die holder 2 are all annular, die holder 2 is socketed on the bottom outside of die head 1, the bottom outside face of die head 1 is provided with the groove for splicing die holder 2, die holder 2 bottoms offer the counterbore for locking nut 3 is installed, and die head 1, die holder 2 are connected to overall structure by locking nut 3.
The material of die head 1 is GCr15, and the material of die holder 2 and locking nut 3 is steel No. 45.
The outer surface line cutting processing of die head 1 has decile tooth.The mould tooth of die head 1 just can be cut directly and be processed by line, turns over that mould will save time, laborsaving, material saving than pincers worker.Die holder 2 and locking nut 3 are also easy processing parts.
Concave-convex mold is the structure of edge body formula, and this structure processing is easy, and machining accuracy is high, the good product quality processing, and labor strength is low, and production efficiency significantly improves, and has saved raw material, has improved economic benefit.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
