본 발명은 도어록 실린더의 나사전조방법에 관한 것으로 고정대의 측벽 상, 하에 근접 설치된 나사로울러가 회전되게하고 도어록 실린더가 삽입되는 접속구는 공회전되게 하여 도어록 실린더의 나사성형부를 나사로울러의 사이에 밀착함으로써 매끈하고 균일한 나사면을 간편하게 전조되게 한 것이다.The present invention relates to a screw rolling method of a door lock cylinder, and the screw roller is installed close to the top and bottom of the side wall of the fixing rod to rotate, and the connecting port into which the door lock cylinder is inserted is rotated to smoothly close the screw forming part of the door lock cylinder between the screw rollers. And uniform screw surface is easily rolled.

통상적인 도어록 실린더의 나사면을 전조하는 방법으로 선반가공하거나 도어록 실린더가 중앙에 놓인 상태에서 양측의 나사로울러를 밀착전조되게 한 것이 있었다. 그러나 이와 같은 방법은 도어록 실린더의 나사성형부가 중공부로 되어 있기 때문에 밀착과정에서 두께가 얇은 나사성형부가 내측으로 쭈그러지고 변형을 일으키케 되어 불량품이 많이 발생하고 작업능률로 떨어지는 결점이 있었다.There was a method of rolling the threaded surface of a conventional door lock cylinder, or making the screw rollers on both sides closely rolled while the door lock cylinder was centered. However, in this method, since the screw molding part of the door lock cylinder is a hollow part, the thin screw molding part is crushed to the inside and causes deformation, resulting in a lot of defective products and a decrease in working efficiency.

본 발명은 상기와 같은 문제점을 해소하기 위하여 도어록 실린더의 성형나사부가 나사로울러에 견고하게 밀착되어 전조가 용이하게 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above problems, the molding screw of the door lock cylinder is firmly adhered to the screw roller to facilitate rolling, which will be described in detail with reference to the accompanying drawings.

고정대(1)의 측벽 상, 하에 나사로울러(2), (2')를 근접되게 설치하여 회전축(2a)으로 일방향 회전되게 하고 이동대(4)의 접속구(5)는 축봉(5a)에 연결되어 공회전하며 접속구(5)에 중공부(6a)로 이루어진 도어록 실린더(6)를 삽입하여 나사로울러(2), (2')의 나사홈(3), (3') 사이에 도어록 실린더(6)의 나사성형부(7)가 밀착하여 나사면(8)을 전조되게 한 것이다.Screw rollers (2) and (2 ') are installed in close proximity to and below the side wall of the fixing table (1) so as to rotate in one direction with the rotating shaft (2a), and the connecting port (5) of the moving table (4) is connected to the shaft (5a) The door lock cylinder 6 between the screw grooves 3 and 3 'of the screw rollers 2 and 2' by inserting the door lock cylinder 6 of the hollow portion 6a into the connection port 5 and idling. Screwed portion (7) is in close contact to roll the screw surface (8).

도면중 미설명부호 9는 가압구, 10은 실린더이다.In the figure, reference numeral 9 denotes a pressurization port, and 10 denotes a cylinder.

이와 같이된 본 발명은 고정대(1)의 측벽에 설치된 나사로울러(2), (2')가 계속적으로 회전하는 상태에서 접속구(5)에 삽입된 도어록 실린더(6)의 성형나사부(7)를 나사홈(3), (3')에 밀착하여 가압하면 나사로울러(2), (2')가 일방향으로 회전하면서 종회전되는 접속구(5)에 삽입된 도어록 실린더(6)의 나사성형부(7)가 밀착되어 회전하므로 나사면(8)을 전조하게 된다.In the present invention as described above, the forming screw portion 7 of the door lock cylinder 6 inserted into the connector 5 in the state where the screw rollers 2 and 2 'installed on the side wall of the holder 1 is continuously rotated. When pressurized in close contact with the screw grooves 3 and 3 ', the thread forming portion of the door lock cylinder 6 inserted into the connector 5 in which the screw rollers 2 and 2' are rotated in one direction and rotated in one direction ( 7) is in close contact and rotates to roll the screw surface (8).

이때 접속구(5)에 삽입된 도어록 실린더(6)의 중공부(6a)내경이 접속구(5)의 외경보다 크더라도 나사로울러(2), (2')의 사이에 전조되는 부분의 나사성형부(7)는 접속구(5)로 밀착되어 있어 내측으로 쭈그러지거나 변형이 되지않고 매끈하게 전조가 되며 전조가 되는 반대편의 도어록 실린더(6)의 내경과 접속구(5)의 외경은 이격되어도 공회전될때마다 공회전되어 전조되는 부분은 항상 견고하게 밀착하게 되는 것이다.At this time, even if the inner diameter of the hollow portion 6a of the door lock cylinder 6 inserted into the connector 5 is larger than the outer diameter of the connector 5, the threaded portion of the portion rolled between the screw rollers 2 and 2 '. (7) is in close contact with the connection port (5) so that it is rolled smoothly without crushing or deforming inward, and the inner diameter of the door lock cylinder (6) on the opposite side to be rolled and the outer diameter of the connection port (5) every time idle even The part that is idled and rolled is always tightly attached.

그리고 나사로울러(2), (2')의 나사홈(3), (3')을 각각 다르게 구성하여 상측 나사홈(3)은 나사성형부(7) 표면을 성형이 용이하게 가공하고 하측 나사홈(3')은 완전가공할 수 있게 함으로써 전조를 원활하게 하여 준다.In addition, the screw rollers 3 and 3 'of the roller rollers 2 and 2' are configured differently so that the upper screw groove 3 can be easily formed on the surface of the thread forming part 7 and the lower screw The groove 3 'facilitates rolling by allowing complete machining.

따라서 본 발명은 중공부로 된 도어록 실린더의 성형나사부의 두께가 얇더라도 매끈하고 균일하게 나사면을 전조하게 되므로 불량품이 적고 대량생산이 용이하게 작업능률을 향상시키게 되는 것이다.Therefore, in the present invention, even if the thickness of the molding screw portion of the door lock cylinder made of a hollow part is smooth and uniformly rolled the threaded surface, less defective parts and mass production are easy to improve the working efficiency.
