Description
Technical Field
The invention relates to the technical field of forming processes, in particular to a wire glue-scour prevention forming process.
Background
In the current processing technology for forming the terminal through rubber shell wire, the traditional processing procedures comprise a plug penetrating process, a terminal punching process, a rubber shell penetrating process, a plug inserting process and a forming outer die, wherein the plug inserting process and the plug penetrating process are used for limiting a core wire and an electric wire so as to avoid dislocation in the terminal punching process and the rubber shell penetrating process;
it needs manual to go on to wear the stopper, if the gluey shell of porous position needs a large amount of handlings consuming time, can't grasp the elasticity completely when wearing the stopper simultaneously, sends the dashing of certain probability in the time of can leading to the shaping and glues, influences the terminal and wears the quality of gluey shell outside wire rod.
In recent years, the cost of personnel is gradually increased in production and processing, and the cost of personnel and time is increased due to the fact that the plug is penetrated, so that the profit is reduced.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a wire anti-scour molding process which can solve the problems in the background art.
The technical scheme adopted by the invention for solving the technical problems is as follows: the wire glue-scour protection forming process comprises the following steps:
s1, terminal punching: pressing the electric wire and the terminal together by using a stamping die;
s2, forming an inner die: forming a plug and an inner mold outside the terminal and the wire by an injection molding technique;
s3, penetrating a rubber shell: inserting the terminal into the rubber shell for fixing;
s4, molding the outer die: and forming an external mold outside the product manufactured in the above step by using an injection molding technique.
Further, before the step S1, the rubber sheet outside the electric wire needs to be partially removed according to the production requirement;
further, in the steps S2 and S4, the injection molding temperature is required to be less than the melting point of the wire and the rubber shell;
further, after the step S3, self-checking the quality of the rubber-covered shell is required, and defective products which do not meet the process requirements are eliminated;
further, in the step S3, the barb of the terminal is used to clamp the inside of the rubber shell to realize fixed connection;
further, in step S2, the plug and the inner mold are integrally formed.
Compared with the prior art, the invention has the beneficial effects that: according to the wire anti-scour molding process, the structure is not provided with an independent plug, and the structure combining the plug and the internal mold function is molded and processed by directly adopting a molding mode, so that the step of plugging the plug in the process is avoided, the production efficiency of the product is improved and the cost is saved on one hand, and the tightness of the plug part and the terminal is ensured on the other hand to improve the production quality of the product; the invention only provides a processing technology, and for similar products, the structure of the die can be modified and the processing technology can be applied, so that the application scenes are wide.
Drawings
FIG. 1 is a process flow diagram of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a first preferred embodiment of the present invention is shown, which realizes simultaneous molding of an inner mold and a plug by modifying the structure of the inner mold, effectively avoiding personnel and time costs caused by plug piercing, and simultaneously ensuring the tightness of the plug piercing process.
The specific design scheme of this example is as follows:
the wire glue-scour protection forming process comprises the following steps:
s1, terminal punching: pressing the electric wire and the terminal together by using a stamping die, wherein the parts pressed in the same mortise are the inside of the exposed electric wire and the terminal;
before step S1, the rubber sheet outside the electric wire needs to be partially removed according to the production requirement;
s2, forming an inner die: forming a plug and an inner mold outside the terminal and the wire by an injection molding technique;
the plug and the inner mold are of an integrated structure, different parts are named only for explaining the functions of the different parts, and the temperature of injection molding in the step S2 is not higher than the melting point of the wire, so that the structure and the function of the wire are prevented from being influenced when the inner mold and the plug are molded;
s3, penetrating a rubber shell: inserting the terminal into the rubber shell for fixing;
the terminal and the rubber shell are fixed through the barb on the terminal clamped in the barb groove on the inner wall of the rubber shell, the quality of the rubber shell needs to be self-checked after the rubber shell is threaded, and the situations that the terminal is threaded askew, the rubber of the electric wire is damaged, the core wire is dislocated and the like are avoided;
s4, molding the outer die: and forming an external mold outside the product manufactured in the above step by using an injection molding technique.
In conclusion, the beneficial effects of the invention are as follows: according to the wire anti-scour molding process, the structure is not provided with an independent plug, and the structure combining the plug and the internal mold function is molded and processed by directly adopting a molding mode, so that the step of plugging the plug in the process is avoided, the production efficiency of the product is improved and the cost is saved on one hand, and the tightness of the plug part and the terminal is ensured on the other hand to improve the production quality of the product; the invention only provides a processing technology, and for similar products, the structure of the die can be modified and the processing technology can be applied, so that the application scenes are wide.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
