Description

Ball type housing molding method

The invention relates to a ball type casing; in particular to a method for guiding a hole forming process, a plane forming process, a cavity forming process, a shaping and a restriction zone processing of the same metal thin plate by the same distance method by moving the equidistant method; The bottom side wing forming process, the guide groove forming process, the cutting and separating process, and the like produce a finished ball bearing housing having a guiding direction of the guiding groove and a direction parallel to the receiving direction of the receiving chamber.

According to the conventional ball type casing, the method comprises the following steps: (A) cutting processing: inserting a strip-shaped strip of a predetermined width into a first mold on the first machine for cutting into a predetermined a base material of a size; (B) a planar forming process; inserting one end of the cut substrate into a second mold on a second machine table, and forming a plurality of different positions to form a punch (C) chamber molding process: inserting the base plate with the unrolled plane into the third mold on the third machine, and punching to form a convex shape through different depth processing (D) Integer and restricted area processing: inserting the base plate which has been punched with the convex chamber into the fourth mold on the fourth machine, and forming through the processing of the punching and finishing zone Half-dimensionally unfolded rudimentary plane; (E) Bottom flank forming process: a base plate having a semi-dimensionally expanded slab plane is placed in a fifth mold on the fifth machine, and is bent to form a downwardly curved bottom flank (F) Guide groove forming process: placing the base plate with the bottom wing on the sixth machine In the sixth mold on the stage, a sixth closed mold is punched and formed to form a nearly closed guide groove to form a prototype shell; (E) cutting and separating processing: a base sheet having a prototype shell The seventh mold is placed in the seventh machine, and then the cutting and separating process of the seventh mold is used to separate the prototype shell from the base sheet; (F) the finished product: to be taken out from the seventh mold, that is, a finished product is completed.

Although the prior art can improve the various defects of the previous cover, and its creation can achieve its creative purpose, and is deeply loved by consumers, when it is manufactured, it will have the following defects: due to the manufacture of the shell When the body is used, it must be cut and processed first, followed by steps such as unfolding plane forming processing, chamber forming processing, shaping and limiting area processing, bottom side wing forming processing, guide groove forming processing, cutting and separating processing, etc. The required steps for producing a single casing are quite numerous, and at the same time, the relatively large amount of waste generated is a major problem.

As mentioned above, since at least seven machines and seven different molds are required for manufacturing, it is necessary to have sufficient plant space for the relevant machines and molds to be placed, thereby causing the cost of renting or purchasing the factory. Greatly increased it is a big problem.

In view of the above, the inventors have actively developed research, and in order to improve the lack of the above-described ball-type housing, the inventors have been engaged in the manufacture of such products for many years, and after long-term efforts and experiments, finally developed and designed. The ball type casing molding method of the present invention can benefit all consumers and manufacturers.

The main content of the ball type casing molding method of the present invention is to provide a guide hole forming process for the same metal thin plate by moving the equidistant method. A shell finished product is manufactured by performing steps of planar forming processing, chamber molding processing, shaping and limiting area processing, bottom side wing forming processing, guide groove forming processing, cutting separation processing, etc., wherein the thin sheet is placed in the mold set and After the punching hole is formed by the punching, the thin plate having the guiding hole is moved forward one more time or more, and then the same thin plate is synchronously punched into another row of guiding holes and the unfolding plane. After the sheet is further moved forward for more than one same stroke, the mold group is simultaneously punched into the same sheet to form another row of guide holes, unfolding planes and convex chambers, and then continuing the sheet. After moving the same stroke more than once, the mold group is re-punched to form the other thin guide hole, the unfolding plane, the convex-shaped chamber, and the bottom flap, and then the sheet is further moved forward. After one or more identical strokes, the mold set is re-punched to form another row of guide holes, a developed plane, a convex-shaped chamber, a bent bottom wing, and a bent guide groove. The guiding direction of the guiding groove is parallel to the receiving direction of the receiving chamber; after the thin plate is further moved forward for more than one same stroke, the mold group is re-punched to the same thin plate to form another guiding guide. a guide hole formed by the hole, the unfolding plane, the convex-shaped chamber, the bent bottom wing, the bent guide groove, and the separation and separation from the thin plate by the cutting and separating process (ie, the guide groove) The finished product of the guiding direction is parallel to the accommodating direction of the chamber; thus, not only the same machine and the same mold can manufacture the housing with the precision superior to the conventional technology for the same thin plate, In addition to improving its yield, production and production capacity, it can also significantly reduce the production of scrap due to the sharp increase in precision, so as to reduce its cost and greatly enhance its market competitiveness and market share. The rate is its progressive claim.
