Abstract
본 발명은 기출원된 본 출원인의 선발명인 국내 특허출원 제96-10244호를 적극적으로 개선한 비디오테이프 카세트용 서포트스프링의 제조방법 및 그 장치에 관한 것으로, 특히 1회의 가공공정에 의해 복수개 이상으로 서포트스프링을 완성가공함에 있어 이를 수행하는 가공공정을 보다 완벽하게 구현시킬 수 있도록 한 것으로, 서포트스프링에 요구되는 규정치 이상의 텐션력을 부여하기 위한 절곡성형공정시 1차 절단된 복수개 이상의 각 서포트스프링이 1회의 성형공정에 의해 상호 대향되게 절곡되도록 하여, 1차 복수면 절단과정에서 발생될 수 있는 절단면의 버르(Burr)로 인한 절곡공정에서의 서포트스프링 뒤틀림현상을 근본적으로 방지하고, 최종절단공정시 그 절단작업이 용이하도록 함으로써, 완성되는 제품의 불량발생을 극소화하고 작업성을 극대화시킬 수 있도록 한 데에 그 특징이 있다.The present invention relates to a method and apparatus for manufacturing a support spring for a videotape cassette, which has been actively improved in the presently-pending applicant's prior patent application, Korean Patent Application No. 96-10244. In the completion of supporting spring, it is possible to more fully implement the machining process that performs this process.At least one of the supporting springs cut at the first molding during the bending molding process to give a tension greater than the prescribed value required for the support spring By bending them to face each other by one molding process, it is possible to fundamentally prevent the support spring distortion in the bending process due to the burr of the cutting surface that can be generated in the first multi-face cutting process, and during the final cutting process By making the cutting work easy, it minimizes the occurrence of defects in the finished product and To help you to be able to have conversations its features.

본 발명은 비디오테이프 카세트용 서포트스프링의 제조방법 및 그 장치에 관한 것으로, 특히 소성가공장치하에서 1회 공정과정에 의해 복수개 이상의 서포트스프링을 완성가공하는 것에 있어서,1차 절단공정을 거친 복수개의 서포트스프링에 요구되는 규정치 이상의 텐션력을 부여하는 가공공정시 복수개 이상으로 1차 절단된 각 서포트스프링이 상호 대향되게 절곡되도록하여, 1차 절단공정에서 발생될 수 있는 절단면의 버르(Burr)로 인한 절곡공정에서의 서포트스프링 뒤틀림현상을 방지하고, 최종 절단공정시 그 절단작업이 방해받지 않도록 한 비디오테이프 카세트용 서포트스프링의 제조방법 및 장치에 관한 것이다.용되는 주요구성부품 중 하나로서, 비디오테이프를 감는 양측릴을 일정한 압력으로 눌러주어 비디오데이프가 감기거나 풀릴 때 그 상태를 일정하게 유지시키는 역할을 수행하도록 되어 있다.있다.연속 이송시켜 상,하부금형(3)(4) 사이를 통과시키는 도중 상기 소재(A)의 이송시점과 일치되는 위치에서 상,하부금형(3)(4)이 승,하강 동작되도록 하여, 1회 동작에 의해 복수개 이상의 서포트스프링(15)을 순차적으로 완성가공하도록 구성되어 있다.수개 이상으로 형성되어 있는 펀치(6)(7)(8)로써 펀칭작업과 성형절단작업을 동시에 행하여 소재(A)의 지지면(16)상으로 복수개 이상의 고정지지공(17) 및 다각요홈공(18)을 각각 형성시킴과 동시에 지지면(16) 양측에는 후술하는 탄력부(19)의 일측면 외형이 복수개 이상으로 성형되도록 한다.의해 상부측으로 절곡형성되도록 하여, 복수개 이상으로 1차 선절단된 각 서포트스프링(15)의 탄력부(19)가 1회 성형동작에 의해 상호 대칭적인 형태를 갖도록 한다.뒤틀림현상이 근본적으로 방지되고, 최종절단공정시 그 절단작업에 장애를 주지 않게 되어, 완성되는 서포트스프링의 불량발생을 최소화하고 작업성을 극대화시킬 수 있는 등의 여러 장점을 갖는다.The present invention relates to a method for manufacturing a support spring for a videotape cassette and a device therefor. In particular, in the processing of a plurality of support springs by one process under a plastic processing apparatus, a plurality of supports that have undergone a primary cutting process In the process of applying tension over the required value to the spring, each of the support springs cut into the plurality of primary cuts is bent to face each other, so that the bending of the cutting surface may occur in the primary cutting process. The present invention relates to a method and apparatus for manufacturing a support spring for a videotape cassette, which prevents distortion of the support spring in the process and prevents the cutting work from being interrupted during the final cutting process. Press both sides of the reel to a constant pressure so that when the video tape is The upper and lower molds are formed at a position coinciding with the transfer point of the material A while continuously passing the upper and lower molds 3 and 4 to pass them. (3) It is comprised so that 4 or more support springs 15 may be sequentially completed by one operation | movement so that a raise and lower operation may be carried out. The punch 6 or 7 formed by several or more ( 8) punching work and forming cutting work simultaneously to form a plurality of fixed support holes 17 and polygonal recesses 18 on the support surface 16 of the material A, and at the same time support surface 16 One side of the elastic portion 19 to be described later on both sides is to be molded into a plurality or more. By bending to the upper side by, the elastic portion 19 of each support spring 15 is first pre-cut to a plurality or more To have a symmetrical form by one molding operation The warpage phenomenon is fundamentally prevented and the cutting operation is not impeded during the final cutting process, thereby minimizing the occurrence of defective support springs and maximizing workability.
