Description

CROSS REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit of Korean Patent Application No. 10-2018-0023194, filed on Feb. 26, 2018, which is hereby incorporated by reference in its entirety into this application.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates generally to a die for manufacturing shims and, more particularly, to a die having a plurality of divisions through which a source material plate is repeatedly moved and pressed into various types of shims, which are in turn automatically sorted and collected by the types without being mixed, thereby manufacturing a great quantity of shims using the source material plate with minimal loss of materials.

Description of the Related Art

Generally, in a conventional process of manufacturing shims, a source material plate should be cut into at least 50 shims. Here, if the 50 shims are cut simultaneously in a die, a problem arises in that the die is damaged due to the limit of rigidity thereof.
Further, in the case of using a cutting method, rather than a die forming method, after a source material plate is marked with shim forms to be cut, the marked shim forms are cut into shims with a complex cutting process using e.g. metal-cutting scissors, wire-cutting, saw-cutting, etc.
However, the conventional process has problems in that in the course of manufacturing the shims, loss of materials occurs, and the source material plate is curved so that the shape of the shim is deformed to degrade the quality of the shim.
Therefore, it is currently required to provide a technique of manufacturing a great quantity of shims in a short period of time with minimal loss of a source material.
The foregoing is intended merely to aid in the understanding of the background of the present invention, and is not intended to mean that the present invention falls within the purview of the related art that is already known to those skilled in the art.

DETAILED DESCRIPTION OF THE INVENTION

Hereinbelow, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the embodiments are merely provided for easy understanding of the invention, so the present invention is not limited thereto.
FIG. 1 is a view illustrating a configuration of a die 100 for manufacturing shims according to an embodiment of the present invention.
Referring to FIG. 1, the die 100 may generally include a lower die block 110, an upper die block 120, and a collecting box 130.
The lower die block 110 may serve as a place on which a source material plate for a shim is seated and located, with a plurality of die divisions formed on an upper surface thereof.
Specifically, the lower die block 110 may be divided into first to fourth die units 111, 112, 113, 114 adjacent to first to fourth sides thereof (not shown).
Here, the first to fourth die units 111, 112, 113, 114 may be coupled to an upper surface of the lower die block 110 by means of one or more bolts. Thus, the first and fourth die units 111, 112, 113, 114 may be respectively decoupled from the lower die block 110. The first to fourth die units 111, 112, 113, 114 may have different shapes, so the die units may be replaced with new die units or other die units having different shapes.
The first die unit 111 may be a die unit which is provided on the upward left side on the lower die block 110, the second die unit 112 may be a die unit which is provided on the upward right side on the lower die block 110, the third die unit 113 may be a die unit which is provided on the downward right side on the lower die block 110, and the fourth die unit 114 may be a die unit which is provided on the downward left side on the lower die block 110. The reason why the first to fourth die units 111, 112, 113, 114 are divided is because a source material plate 1 is sequentially moved from the first to the fourth die units 111, 112, 113, 114. Then, the source material plate 1 is first pressed for an empty space by the first die unit 111 and moved to the second die unit. Then, the source material plate 1 is first pressed for an empty space by the first die unit 111 and moved to the second die unit 112. Then, the source material plate 1 is secondarily pressed for an empty space by the second die unit 112 and moved to the third die unit 113. Then, the source material plate 1 is thirdly pressed for an empty space by the third die unit 113 and moved to the fourth die unit 114. Finally, the source material plate 1 is fourthly pressed for an empty space by the fourth die unit 114.
With the multiple pressing stages, a plurality of shims 1 a may be manufactured from the source material plate 1.
Here, since the first die unit 111 may have about 15 shim-shaped forming parts, the first pressing stage may produce 15 shims 1 a.
Further, since the second die unit 112 may have about 10 shim-shaped forming parts, the second pressing stage may produce 10 shims 1 a.
Further, since the third die unit 113 may have about 15 shim-shaped forming parts, the third pressing stage may produce 15 shims 1 a.
Finally, since the fourth die unit 114 may have about 10 shim-shaped forming parts, the fourth pressing stage may produce 10 shims 1 a.
That is, consequently, while the source material plate 1 is moved from the first die unit 111 to the fourth die unit 114, at least 50 shims 1 a may be produced from the source material plate through four pressing stages, and the 50 shims 1 a are downwardly discharged toward the collecting box 130.
Collecting channels (not shown) may be provided between the first to fourth die units 111, 112, 113, 114 and the collecting box 130 to allow the shims 1 a to be discharged therethrough.
In the meantime, although FIG. 1 illustrates that the lower die block 110 is divided into four sections, i.e. the first to fourth die units 111, 112, 113, 114, the first die unit 111 may mean a combination of total 15 forming parts which are bolted to the lower die block 110, the second die unit 112 may mean a combination of total 10 forming parts which are bolted to the lower die block 110, the third die unit 113 may mean a combination of total 15 forming parts which are bolted to the lower die block 110, and the fourth die unit 114 may mean a combination of total 15 forming parts which are bolted to the lower die block 110.
That is, while FIG. 1 illustrates four die units, the four die units may include 50 forming parts which are respectively bolted to the lower die block 110 to suit respective shapes of shims.
Next, the upper die block 120 is located opposite the upper surface of the lower die block 110, wherein a lower surface thereof may correspond to the upper surface of the lower die block 110, i.e. the first to fourth die units 111, 112, 113, 114. The upper die block 120 may be provided so as to be vertically movable downwards from the upper side of the lower die block 110, so that the upper die block serves to downwardly press the source material plate seated and located on the first to fourth die units 111, 112, 113, 114.
The upper die block 120 may be divided into fifth to eighth die units 121, 122, 123, 124 adjacent to fifth to eighth sides thereof (not shown), opposite the first to fourth die units 111, 112, 113, 114.
Here, the fifth to eighth die units 121, 122, 123, 124 may be coupled to the upper die block 120 by means of a plurality of bolts, so the fifth to eighth die units may be respectively separated from the lower side of the upper die block 120.
When coming into contact with each other, the first to fourth die units 111, 112, 113, 114 and the fifth to eighth die units 121, 122, 123, 124 may have the same contact surface.
Since the first to fourth die units 111, 112, 113, 114 and the fifth to eighth die units 121, 122, 123, 124 have the same function except for their locations, a detailed description thereof will be omitted. Like the first to fourth die units 111, 112, 113, 114, the fifth to eighth die units 121, 122, 123, 124 are bolted to the upper die block in order to be replaced with new die units or other die units having different shapes, if needed.
In an embodiment, the first to fourth die units 111, 112, 113, 114 may be provided on the respective sides thereof with one or more protrusions 115 to prevent the source material plate 1 from turning off the first to fourth die units 111, 112, 113, 114.
Thus, while the source material plate 1 is moved from the first die unit 111 to the fourth die unit 114, the source material plate is prevented from turning off the first to fourth die units 111, 112, 113, 114 by the protrusions 115.
In the meantime, although FIG. 1 illustrates that the upper die block 120 is divided into four sections, i.e. the fifth to eighth die units 121, 122, 123, 124, the fifth die unit 121 may mean a combination of total 15 forming parts which are bolted to the upper die block 210, the sixth die unit 122 may mean a combination of total 10 forming parts which are bolted to the upper die block 120, the seventh die unit 123 may mean a combination of total 15 forming parts which are bolted to the upper die block 120, and the eighth die unit 124 may mean a combination of total 15 forming parts which are bolted to the upper die block 120. That is, while FIG. 1 illustrates four die units, the four die units may include 50 forming parts which are respectively bolted to the upper die block 110 to suit respective shapes of shims.
Next, the collecting box 130 is located below the lower die block 110 so as to collect the shims 1 a through collecting channels (not shown) provided below the first to fourth die units 111, 112, 113, 114 of the lower die block 110. This is illustrated in detail in FIGS. 2 and 3.
FIG. 2 is a detailed view illustrating a collecting box 130 of the die illustrated in FIG. 1, and FIG. 3 is a view illustrating shims 1 a being sorted and collected by partition walls 131 a, 132 a of the collecting box 130 illustrated in FIG. 2.
Referring to FIG. 2, the collecting box 130 may include a first collecting box section 131 provided below the first and fourth die units 111, 114, and a second collecting section 132 provided below the second and third die units 112, 113.
The first and second collecting box sections 131, 132 may be able to slide outwards or inwards from the lower die block 110.
Thus, when the first and second collecting box sections 131, 132 are fully collected with the shims 1 a, the first and second collecting box sections 131, 132 are drawn from the lower die block 110 so that the shims collected therein can be obtained.
Referring to FIG. 3, the first and second collecting box sections 131, 132 may be respectively provided with the partition walls 131 a, 132 a, through which the shims 1 a are collected from the first to fourth die units 111, 112, 113, 114.
The partition walls 131 a, 132 a may be configured such that internal spaces of the first and second collecting box sections 131, 132 may be divided into the same number of divisions as the shim-forming parts of the first to fourth die units 111, 112, 113, 114.
That is, in the first die unit 111 of FIG. 1, 15 shims 1 a discharged downwards from the first die unit 111 may be sorted and collected in 15 divisions by the partition walls 131 a of FIG. 3. Further, in the fourth die unit 114 of FIG. 1, 10 shims 1 a discharged downwards from the fourth die unit 114 may be sorted and collected in 10 divisions by the partition walls 131 a of FIG. 3.
Further, in the second die unit 112 of FIG. 1, 10 shims 1 a discharged downwards from the second die unit 112 may be sorted and collected in 10 divisions by the partition walls 132 a of FIG. 3.
Further, in the third die unit 113 of FIG. 1, 10 shims 1 a discharged downwards from the third die unit 113 may be sorted and collected in 15 divisions by the partition walls 132 a of FIG. 3.
The shims 1 a sorted by the partition walls may be about 100 shims for each division.
Although preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
