Description

[0001] The present invention relates to a disk spring hot-working and pressing apparatus,

The present invention relates to a disk spring hot forming apparatus, and more particularly, to a disk spring hot forming apparatus which is provided with a disk spring material supplied in a punching form, And to provide a disk spring hot forming apparatus.

The disk spring to be realized by using the molding apparatus of the present invention is formed by punching a plurality of disk springs inside the disk spring material M And the disk spring material M is bent in the form of a funnel through a hot pressing process so that the elasticity of the wedge pieces P is imparted by the quantity and shape of the wedge pieces P. (See Fig. 2)

The above-described manufacturing of the disk spring is performed by: (1) punching the disk spring material, (2) hot pressing the disk spring material punched, and (3) quenching the disk spring material subjected to hot working The present invention relates to a disc spring hot forming apparatus in which a disc spring material having a first punching process is supplied to finish the forming of a disc spring by hot pressing the disc spring material.

The disk spring material is punched by supplying the disk spring material to the heating means, (2) discharging the disk spring material heated by the heating means, (3) supplying the disk spring material discharged from the heating means to the mold means And a step of taking out the disk spring material subjected to the pressing process from the mold means. In the past, since there is no dedicated equipment for hot forming the disk spring, each process for hot forming the disk spring is called a work force And the like.

Since the conventional disk spring hot forming operation as described above depends on only the workforce, the time required for the work is long and the productivity is low. This is pointed out in that the labor cost and the decrease in the productivity are directly linked to the increase of the cost of the product, In the hot forming process of the disk spring, the disk spring material heated to a high temperature is discharged, and the process of supplying the disk spring to the mold and discharging the disk spring is repeated repeatedly. Therefore, various safety accidents occur during the process .

The present invention has been made in order to overcome the problems of the conventional hot-forming method of the disk spring as described above. When the disk spring material punched is poured, a series of processes such as feeding, heating, pressing, The present invention provides a disc spring hot forming apparatus which is completed with a technical point of view in order to minimize the labor cost and to improve the productivity and to reduce the cost of the product and to prevent various safety accidents in advance I want to.

According to an aspect of the present invention, there is provided a disc spring material comprising: a distribution loader for supplying or discharging a disc spring material having punching processing to each component part; a disk spring material having a punching process within a working radius of the distribution loader A heating part for heating the disk spring material supplied through the supply part, and a forming part for pressing the heated disk spring material, respectively. will be.

In the disk spring hot forming apparatus of the present invention, when a punching disk spring material is put into a supply part, a series of processes such as heat treatment, press working, supply, discharge and take out of the disk spring material are automatically performed will be.

Since the present invention can maximize productivity with a minimum of manpower, it is possible to expect reduction of product cost and inventory effect of product competitiveness, and it is possible to prevent occurrence of various safety accidents because workers do not carry out dangerous process have.

In addition, according to the present invention, since each process is performed according to driving data of each driving part set in advance, the performance of the disc spring due to hot forming can be consistently maintained, and the incidence of defective products can be minimized. The invention will be an invention whose expected effect is indeed beneficial.
