In describing the present invention, if it is determined that a detailed description of a related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, with reference to the accompanying drawings, a hinge manufacturing apparatus according to the present invention (hereinafter, simply referred to as 'manufacturing apparatus') will be described in detail. Prior to the description, the control unit 500 to be described below means a conventional controller provided with a plurality of switches and displays, and the control unit 500 includes the base unit 100 , the punching unit 200 , and the molding unit 300 . ) and the cutting part 400, note that it controls at least one.

First, as shown in FIG. 1 , the manufacturing apparatus 1 according to the present invention largely includes a base part 100 , a punching part 200 , a molding part 300 and a cutting part 400 , and the Forming of a hinge 10 having a first rotating piece 11 and a second rotating piece 12 rotatably coupled to each other around the iron core 30 as a rotation axis through organic coupling allow this to be completed.

In more detail, the base part 100 is, as shown in FIGS. 2 to 5, the control unit 500, as well as the punching part 200, the molding part 300 and the cutting part ( 400) is sequentially installed, the body member 110, the first supply member 120, the second supply member 130, the variable iron core 137 and It includes a scrap member 140 .

For example, the body member 110, as shown, a plurality of frames 111 having a predetermined length in the vertical and horizontal directions are coupled to each other by fastening means such as bolts, etc. It allows the components to be installed to have a predetermined height.

Of course, the body member 110 is further installed with a plate-shaped mounting plate having the same material in addition to the plurality of frames 111 formed of a steel material, so that the basket 143 and the like are detachably installed on the body member 110 . It is also possible to make

In addition, in the lower portion of the body member 110, there is a holder 113 for fixing with the ground in order to prevent the flow of the manufacturing device 1 due to vibrations that may occur during operation of the manufacturing device 1 according to the present invention. It may be additionally installed, and if necessary, it is also possible that wheels (not shown) are additionally provided in addition to the fixing base 113 .

In addition, the first supply member 120 for supplying the raw material 20 of a steel material for forming the first and second rotating pieces 11 and 12 constituting the hinge 10 to the punching unit 200 is shown As described above, it includes a material roller 121, a first rotating plate 122, a first driving motor 123, a supply roller 124, and a guide roller 125 (see FIG. 15).

As shown, the material roller 121 is installed so that both sides can be rotatably coupled between the pair of first rotating plates 122 with the lower portions fixed to the frame 111 adjacent to each other, as shown.

On the outer surface of the material roller 121 , the raw material 20 having a predetermined thickness is wound in the form of a roll, and the end thereof is supplied to the punching unit 200 by rotation.

The rotation of the material roller 121 enables rotation with a driving interval by the first driving motor 123 provided on the outer surface of the pair of first rotating plates 122, and the first driving motor 123 is a control unit (500) so that the rotation speed or direction can be controlled.

At this time, the pair of first rotating plate 122 has both sides of the material roller 121 through a plurality of long holes 127 having a length in the vertical direction while rotating and descending by the weight of the material roller 121 at the same time. It is desirable to be installed so that The reason for this configuration is as follows.

The preferred supply of the raw material 20 supplied to the punching unit 200 is the lowest end of the material roller 121 so that the extraction length of the raw material 20 is extended to a minimum without bending and can be drawn into the punching unit 200 . It is to keep the inlet side of the punching part 200 and horizontal as much as possible.

However, when the material roller 121 is combined with the pair of first rotating plates 122 and a structure that can simply rotate on the spot, when the thickness of the raw material 20 decreases due to long-time use, the material roller ( The distance between the lowermost end of the 121) and the inlet side of the punching unit 200 is relatively far apart, so that problems such as inflow of foreign substances may occur.

In order to solve this problem, the thickness (T) of the raw material 20 wound on the outer surface of the material roller 121 is reduced by the use of the raw material 20 to solve this problem, and the long hole 127 by the weight of the material roller 121 is reduced. ) so that the extraction length of the raw material 20 supplied to the punching unit 200 always has the same condition because it automatically descends along the

On the other hand, in the present invention to further enhance the effect of solving the above-mentioned problems, the supply roller 124 and the guide roller 125 may be additionally used.

Here, as shown, the supply roller 124 is positioned under the material roller 121 installed on the pair of first rotating plates 122 so that both sides can rotate with the first rotating plate 122 on the spot. Installed so that the lowest point of the raw material 20 wound on the outer surface of the material roller 121 lowered by its own weight coincides with the uppermost end of the supply roller 124 .

Furthermore, a plurality of guide rollers 125 may be installed symmetrically to each other on the frame 111 so that both ends of the raw material 20 can be inserted between the supply roller 124 and the punching unit 200, as shown. have.

In this way, the guide roller 125 installed to face each other on the frame 111 is the end of the raw material 20 to be supplied to the punching unit 200 inside the insertion groove 126 formed in a band shape on the outer surface is inserted and supported. It enables stable supply to the punching unit 200 in the state.

At this time, it is preferable to use the guide roller 125 by adjusting the width of the raw material 20 to be supplied to the punching unit 200 by being slidably installed on the frame 111 as shown.

In addition, as shown in FIGS. 5 and 6 , the second supply member 130 for supplying the iron core 30 includes an iron core roller 131 , a second rotating plate 133 , a second driving motor 135 and an iron core. Variant 137 is included.

In the iron core roller 131, an iron core 30 having the shape of a wire is wound in the form of a roll, and the corresponding iron core 30 is rotated by the cutting part 400 through the rotation of the second driving motor 135 controlled by the control unit 500. so that it can be supplied.

Here, the second rotating plate 133 has the same shape and use in which the difference in the supply target and the configuration of the long hole 127 are omitted compared to the above-described first rotating plate 122, and the second driving motor 135 also Since it has the same structure as the first driving motor 123 described above, detailed omissions will be omitted so as not to flow the gist of the present invention.

As shown, the variable iron core 137 is fixedly installed on the frame 111 to be positioned at the front end of the cutting unit 400 , and the iron core 30 before being supplied to the cutting unit 400 is inserted through the inside of the iron core. The iron core 30 having a curved shape at the same time as being unwound from the roller 131 can be changed to a horizontal state through the shape of the iron core variable body 137 .

To this end, in the variable iron core 137, a first through hole 139 extending from the front end to the rear end is perforated so that the iron core 30 can be inserted through and supplied to the cutting unit 400, as shown. The inner surface of the first through hole 139 is formed to have an arc shape in the upper or lower direction, so that it is possible to change the shape of the horizontal state only by the process of passing the iron core 30 through it.

In other words, the iron core 30 made of a steel material wound and supplied in the form of a roll is drawn out to have a curved shape (Z1) in the winding direction at the time of withdrawal due to the characteristics of the material, and this curved shape is maintained. When supplied to the cutting unit 400 in the state, there is a problem that it is not easy to insert into the plurality of rotating holes 14 overlapping each other through the first and second rotating pieces 11 and 12 .

Thus, in the present invention, in order to solve the above problems, the variable iron core 137 is disposed at the front end of the cutting unit 400, but the curved shape of the iron core 30 is inserted through the overall shape of the inner peripheral surface of the first through hole 139. Conversely, by forming (Z2) in a convex arc shape upward or downward to allow the iron core 30 after penetrating the first through hole 139 (Z3) to maintain a horizontal form as much as possible, to be able to solve that problem.

In addition, the scrap member 140 for collecting the scraps of the raw material 20 discarded after the punching part 200 is punched and the first and second rotating pieces 11 and 12 are molded is a scrap roller ( 141) and a basket 143.

As shown, the scrap roller 141 is rotatably installed in the frame 111 to have the shape of a roller so as to be located at the rear end of the punching unit 200, and the first and After the second rotating pieces 11 and 12 are molded, the leftovers for the raw material 20 can be wound in the form of a roll (see FIG. 7 ).

To this end, an adhesive (not shown) may be applied to the outer surface of the scrap roller 141 , that is, the outer surface on which the scraps are wound, and the worker may remove the scraps of the raw material 20 that has passed through the punching unit 200 , the punching unit 200 . When discharged to the exit side of the scrap roller 141, it is possible to induce the scraps having a predetermined length to be wound on the outer surface of the scrap roller 141 by one operation of manually bonding the scraps to the adhesive.

As shown in the figure, the basket 143 is provided in the frame 111 to be positioned between the above-described scrap roller 141 and the punching part 200 and between the forming part 300 and the cutting part 400 to be described later.
