Abstract
The present invention relates to a punch comprising: a plurality of punches (10) installed on an upper side of a core (C) and vertically lifted and lowered to form a plurality of slots radially in the core (C); A punch fixing plate 20 installed on the upper side of the punch 10 to vertically penetrate the punch 10 to fix the punch 10; A punch holder (40) installed on an upper surface of the punch fixing plate (20) and supporting the punch fixing plate (20); A die 80 provided at a lower portion of the punch 10 and supporting a lower end of the core C on an upper surface thereof and having a plurality of punch holes 82 formed in a concentric circle; A punch height adjusting plate 50 installed inside the punch holder 40 and accommodating a part of a plurality of punches 10 arranged in a concentric circle rotated at a predetermined angle to form a height of the punch 10 differently, The present invention relates to a punching die capable of adjusting the punch height.
According to the present invention, since the punching is sequentially performed, the punching force can be reduced as compared with a punching mold in which punching is performed all at once. This makes it possible to perform the same punching process with a low-capacity punching die without using a high-capacity punching die, thereby reducing manufacturing costs.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching die capable of adjusting the height of a punch, and more particularly, to a punching die capable of adjusting a height of a punch disposed on a concentric circle by rotating a punch height control plate.
2. Description of the Related Art Generally, a motor includes a rotor and a stator, and is a mechanism for providing a driving force by rotating the rotor by application of power.
These motors are manufactured by various methods according to their types. Among the motors of the above types, large motors used for industrial equipments and the like are generally manufactured by stamping a circular sheet on a roll steel sheet, To process the respective cores for the manufacture of the rotor and stator.
The rotor core and the stator core processed as described above are laminated under pressure to form a rotor and a stator, respectively, and then the motor is completed through the coupling between the rotor and the stator.
A conventional motor core mold is disclosed in Korean Patent Publication No. 10-0235830.
The punches installed in the molds are installed at the same height to perform the punching process.
However, when a plurality of slots are machined at a time, a stronger punching force must be provided. Therefore, a high-capacity punching die is generally required, which increases the manufacturing cost of the punching die.
In addition, when the height of the punch is varied in order to sequentially punch the plurality of slots without machining simultaneously, the punch must be completely separated from the fixed plate during the polishing of the punch so that the height of the punch is different, There is a problem that not only the repairing time is long but also the working efficiency is low.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a punching die capable of adjusting the height of a punch disposed on a concentric circle, .
According to an aspect of the present invention, there is provided a punching die capable of adjusting the height of a punch according to the present invention, the punching die being provided on an upper side of a core and vertically moving up and down to form a plurality of slots radially in the core A plurality of punches;
A punch holding plate installed on the upper side of the punch and punching up and down to fix the punch; a punch holder installed on an upper surface of the punch holding plate to support the punch holding plate; And a plurality of punch holes provided in the punch holder and rotated in a predetermined angle to form a plurality of punches arranged in a concentric circle, And a punch height adjusting plate for accommodating a part of the punches to form a different height.
Wherein the punch height adjusting plate comprises a rotating body having a circular ring shape and provided inside the punch holder and supporting a plurality of upper surfaces of the punches, and a lower body formed on the lower surface of the rotating body, A plurality of stepped portions formed to be spaced apart from each other by a predetermined depth radially and spaced apart at regular intervals to receive an upper end portion of the punches and formed between the stepped portions and protruding from the stepped portions, As shown in Fig.
One side of the rotating body has a cylindrical shape and is formed to be long in the left and right direction and has a rotating bar which is screwed to one side of the rotating body to rotate the rotating body.
The rotary body is provided with a detent groove formed along a concentric circle of the rotary body and formed with a plurality of recesses in a cylindrical shape at a predetermined angle. The detent groove is provided on the upper side of the detent groove, And a stopper member inserted into the stop groove according to the rotation of the rotation body to adjust a rotation angle of the rotation body.
The punch holder may further include a manipulation hole formed on a circumferential surface of the punch holder, the manipulation hole being formed to penetrate from side to side and guiding the rotation bar to protrude to the outside.
The punching mold capable of adjusting the punch height according to the present invention has the following effects.
The present invention is characterized in that a step portion and a protruding portion are formed alternately along the concentric circle on the lower surface of the punch height adjusting plate and the punch is alternately positioned on the step portion and the protruding portion so that the punch positioned on the protruding portion And the punch located at the stepped portion is punched backward.
Accordingly, the punching force is less than that of the punching mold in which the punching is performed sequentially, and the punching is performed all at once. This makes it possible to perform the same punching process with a low-capacity punching die without using a high-capacity punching die, thereby reducing manufacturing costs.
Further, since the height of the protrusion of the punch can be changed to the same height by rotating the punch height adjusting plate when the punch is polished, and a plurality of punches can be polished at the same time, there is an advantage that the polishing time of the punch is minimized, TEk.
