Abstract

PURPOSE:To cause no loss of a material and also to raise remarkably the forming accuracy, by loading successively a metallic wire rod shorn to prescribed size in plural die holes, and pressing it to formed parts which is formed as one body with a whirl-stop projection on the circumferential side. CONSTITUTION:A metallic wire rod 1 is shorn by cutting edges 2, 2, an obtained parts forming member 1a of prescribed size is led and loaded into a shaping die 3a, the primary die formation is executed by a forming punch (a), also a punch 5a is projected, and intermediate formed parts 1b are obtained. Subsequently, these parts 1b are led and loaded into a shaping die 3b, and the secondary die formation is executed by a punch 4b. The final formed goods 1m are obtained by passing through successively suitable plural processes such as loading, die formation and projecting operation in comformity with object formed parts. During this time, in case of die formation to the members 1a-m, a projection 1x for turn whirl-stop is extruded to the side successively, and pressed like a projecting lever in the end. This formed goods are used for machine parts, especially, various pin members.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to mechanical parts, especially various pin members and brace devices.
It is our intention to provide a full range of services.

Previously, the mechanical parts of this company were generally cut by shirring a wire such as a coil material.
La dimension IC Nasu and IC.

I took this f1r tool, cut it, didn't have the desired bottle shape CC, and then did the chucking process? After that, a small hole r is drilled with the tool 11, and a pin R of IE is press-fitted around this small hole to form a rotation-stopping part.

However, in the conventional method, first of all, shearing and cutting with a cutting tool are performed, and during the cutting process, cutting waste corresponding to the width of the saw blade, etc., is generated.

Father, this is probably f'F in the setting process such as shirring, press-fitting, etc.
This is a time-consuming process and often results in incorrect settings such as setting errors.

The method for forming the mechanical parts with 4E mating pins and special pins related to the IC of the present invention is a method for forming special pins in view of the inconveniences in the conventional manufacturing method, and the method is not devised specially for the mechanical parts such as coil materials, etc. Cutting the wire rod; in addition to removing the shearing waste, the time required for this cutting is shortened by 11C, and the wire rod is cut into a straight cut shape.
Cutting parts that tend to be irregularly shaped Sugihara press shop 'fl-
The pieces were then shaped and molded into the desired part shape using the press.

Due to this unique molding method, there is no loss in the material provided, and the Eisugi efficiency is 11%, and the pre-formed material is 0% per unit time. be.

In addition, in this method, the generation of waste products is small, and it is guaranteed that parts with the desired shape can be formed reliably, and if the morphological composition of the molded parts is particularly dense, it is possible to reduce the production of finished products, etc. A special product with a high hardness was offered.

Father, fl)\'s method number There is no cutting experiment etc. in this case, and when the 11 round surface is broken, there is no joint number extrusion at all, Itf! This eliminates the possibility of injury to hands or fingers or accidents caused by getting caught.

The present invention is a method for molding such mechanical parts, especially in order to achieve the desired effects of various custom orders. Summary of #IIE The long metal wires v5gl are sequentially provided and are sequentially pressed to fit the dimensions of the 5gl cedar part, and the formed material r that is press-cut and provided is sequentially loaded into multiple die holes in the city. Gradually, the predetermined part shape (this pressing FN, in the process of shaping, the core forming cedar parts station 11111 surface number this rounded market protrusion r integrally pressed if swelled 11M), the following points are pressed. The specific actual M example and the considerable design changes accompanying these central elliptical examples were not planned.

Hereinafter, the present invention (this invention will be explained in detail with reference to the accompanying drawings, which are typical examples of waveform techniques such as mechanical parts, pins, etc.). Immediate response to parts) iV, hardness? Is this a coil material made of various metals or non-ferrous metals? Cutting blade 12)
, 12) Push off with r, parts of specified dimensions + 1isU
It'6 members Ill 2 and K ones.

h) The member 111a that was provided with a push-cut has some distortion in the safe, especially since the cut surface is irregular.

This member 11J a k is guided into the cedar shaping die 131 a, and the forming punch (4) a is used to form the next pattern p.
ff and ejection punch f51 a 7F are used to eject the protrusion from the press device to form an intermediate original member, and then guide it into the cedar shaping die Mb for the next process, and punch 141.
b? It is arranged so that the second molding r is performed.

For the loading, molding, and ejecting operations 1'E', prepare multiple pieces of Eisugi according to the shape, number, etc. of the desired Eisugi parts, and strain each to obtain the final ready-made cedar product + 11 mq. be.

In addition, this member 111a...ml (when mounting it on the wall, turn it around and push it out sideways one after another, and make the final piece a protruding rod shape?! 7r, r). It was planned.

The parts mentioned in Section 1 are most typically machine parts.
Regarding the 5'1FfA method of pins with IE pins that can be worn out), it is a water-pepped y= thing, but it also affects the development of various other parts made with this basic pin (old condition of this pin). This one, which has been deemed optimal, is beyond genius.

In this method, there is no generation of cutting debris on the metal wire 111, and it is commonly used in molding. There is no generation of cutting waste, and all of the wire rods provided are made from recycled parts, making the material cost for molded parts relatively low.

My father, Seisai's everything is pressed ((The molding is not only done by the method, but also by setting it by chucking, etc.)
No need and work efficiency? Dramatically increasing and exceptionally skilled?
This makes it possible for anyone to mass-produce parts with the desired shape without any hassle. That is, h)″
In the above method, only uniform part specifications are possible, and the possibility of unfavorable products is reduced as much as possible.

Next, by using the breath coloring process, the corners of the parts to be painted are always given a constant rounded surface, there is no flashing in the core, and the fit-in characteristics during machine assembly etc. It was marked as '#+ Good luck.

In the pressure coloring method, the composition of the circumferential surface of the shaped part is a particularly dense layer +111, which significantly increases the strength of the molded part, and improves wear resistance, impact resistance, etc. wt
This improves the quenching effect by %.

In addition, in the previous precedent, the main body of the cedar was prepared by shearing, cutting with a cutting tool, etc., and at the same time, a hole was made with a drill, and a pin round was made into a thousand pieces. This increases the material cost, increases the molding cost due to the increased processing time, and improves the wear resistance of molded parts.
Poor impact resistance properties 111. In addition, problems such as the pin 11) becoming rattled or falling off, and assembly due to deformation of the pin 11) caused various problems such as poor fitting. Featured T
llt [ii From Z, are these inconveniences in secondary cutting examples? [A truly sweeping and simple method of enrichment? This makes it possible to provide high quality products at low cost.
