Description

Fixed rod integrated molding manufacturing method

The present invention relates to a related art for manufacturing a rod body, and more particularly to a method for integrally forming a fixed rod.

As is generally shown in FIG. 7, the conventional fixing rod 200 includes a sharp portion 201, a ring portion 202, and a body portion 203. Both ends of the body portion 203 are connected to the sharp portion 201 and the ring portion 202, and the ring portion 202 is connected. One end of the welded portion 204 is connected to the body portion 203 by welding, and the sharp portion 201, the ring portion 202, and the body portion 203 are made of the same material, and the material of the welded portion 204 is different from the body portion 203 and the ring portion 202. Therefore, if it is used for a long time, the welded portion 204 is easily broken and separated, and must be finished.

In addition, referring to FIG. 8 again, the fixing rod 300 of another embodiment includes a sharp portion 301, a ring portion 304 and a body portion 303, and the ring portion 204 is outwardly protruded to form a male thread portion 305, and the body portion One end of the 303 is connected to the sharp portion 301, and the other end of the body portion 303 is a female thread portion 302. The outer ring portion 304 of the ring portion 304 is detachably screwed with the female thread portion 302 of the body portion 303; however, In the screwing manner, the strength between the ring portion 304 and the body portion 303 is not strong enough. In the case of a long-term force application, the threaded portion 305 outside the ring portion 304 is easily broken, or the internal thread portion 302 is broken. It must be handled again, which is very troublesome.

The invention provides a method for integrally forming a fixed rod, which is to manufacture an integrally formed fixing rod, which not only enhances the hardness, but also avoids breaking for a long time and further prolongs the service life.

The present invention provides a method for integrally forming a fixed rod, the steps of which include: Step S1: inserting a long straight rod into a first mold, the first mold having a first a first semicircular groove is recessed at one end of the first body, the long perforation is passed through the first body, and from the first semicircular groove The first body is disposed away from one end of the first semicircular groove, the long perforation is in communication with the first semicircular groove, the oblong straight bar is inserted into the long perforation, and protrudes outward from the first semicircular groove; S2: a second mold corresponding to the first mold is disposed on the end of the first semicircular groove, and the second mold has a second body and a second semicircular groove. The second mold has a second body and a second semicircular groove. a semicircular groove is recessed at one end of the second body corresponding to the first semicircular groove, and the end of the long straight bar protruding from the first semicircular groove is topped into the second semicircular groove of the second mold; step S3 Fixing the long straight rod through one end of the long hole of the first mold, and pushing the second mold toward the first mold until the first semicircular groove and the second semicircular groove are combined into one a circular groove such that the long straight rod is originally in the first semicircular groove and the second semicircular groove Part of the extrusion to form a round cake portion in the circular groove; and step S4: separating the first mold and the second mold, and taking out the long straight rod having the round cake portion, and then the round cake portion Processing.

The inner bottom surface of the first semicircular groove and/or the inner top surface of the second semicircular groove are formed with a top abutting plane.

In some embodiments, processing the wafer portion in step S4 includes performing a perforation process on the center of the wafer portion and smoothing the outer periphery of the wafer portion.

Referring to FIG. 1 to FIG. 6 , the method for manufacturing the fixed rod integrated molding of the present invention comprises the following steps: Step S1 : inserting a long straight rod 1 into a first mold 100 , the first mold 100 having a a first body 110, a long perforation 120, and a first semicircular groove 130. The first semicircular groove 130 is recessed at one end of the first body 110, and the long perforation 120 is disposed in the first body 110, and is The semicircular groove 130 and the first body 110 are disposed away from one end of the first semicircular groove 130. The long perforation 120 is in communication with the first semicircular groove 130, and the oblong straight bar 1 is inserted into the long perforation 120 and is directed from the first semicircular groove 130. Step S2: a second mold 200 disposed corresponding to the first mold 100 protrudes from the long straight rod 1 and protrudes from one end of the first semicircular groove 130. The second mold 200 has a second body 210 and a The second semicircular groove 220 is recessed at one end of the second body 210 corresponding to the first semicircular groove 130. The end of the oblong straight bar 1 protruding from the first semicircular groove 130 is attached to the second die 200. The second semicircular groove 220 is inside; step S3: the fixed long straight rod 1 is worn through the first mold 100 One end of the hole 120 is pushed in the direction of the first mold 100 by the second die 200 until the first semicircular groove 130 and the second semicircular groove 220 are combined into a circular groove, so that the long straight bar 1 is originally in the first semicircular groove 130 and the second semicircular groove 220 are partially pressed to form a round cake portion 2 in a circular groove formed by combining the first semicircular groove 130 and the second semicircular groove 220; and step S4: separating the first mold 100 and the second mold 200 And the long straight rod 1 having the round cake portion 2 is taken out, and the round cake portion 2 is processed.

The inner bottom surface 131 of the first semicircular groove 130 and/or the inner top surface 221 of the second semicircular groove 220 are formed with a top abutting plane.

Further, the processing of the wafer portion 2 in the above step S4 includes forming a through hole 3 and a pair of the round cake portion 2 by punching a center portion of the wafer portion 1 (as shown in FIG. 5). The outer circumference is rounded (as shown in Fig. 4), and the order may be different depending on the design.

According to the above-described manufacturing method, the integrally formed fixing rod can be manufactured, and the manufacturing process is simple, the hardness can be enhanced, and the long-term force is applied to cause breakage, thereby prolonging the service life.
