본 고안은 프레스 기계용 안전장치에 관한 것이다.The present invention relates to a safety device for a press machine.

타발, 드로우잉, 스테이킹 및 업셋팅등과 같이 가동금형이 고정금형을 향하여 이동하는 피가공물의 가공에 있어서, 손수 피가공물을 금형 사이에 장입하고 가공물을 취출해야만 한다.In the processing of workpieces in which the movable mold moves toward the stationary mold, such as punching, drawing, staking, and upsetting, a manual workpiece must be charged between the molds and the workpiece taken out.

이러한 작업들은 작업자를 상해로부터 보호할 수 있는 안전장치가 필요하며, 이것은 법률에 규제되어 있기도하다.These operations require safeguards to protect workers from injury, which are also regulated by law.

이러한 필요성에 입각하여 다양한 안전장치가 제안된바 있으나 그것들은 프레스 기계의 작업능률을 저하시키는 경우가 많다.Various safety devices have been proposed based on these needs, but they often reduce the working efficiency of the press machine.

이와같이 기구가 간단하여 작업능률을 저하시키지 않는 안전수단을 갖춘 프레스 기계가 요구 되지만 충분히 만족할만한 방식은 소수에 불과하다.As such, there is a need for a press machine with safety measures that do not degrade work efficiency due to the simple mechanism, but only a few are satisfactory.

링케이지와 관련제어스위치에 의해 플런저의 작동을 제어하는 방식의 안전장치가 일본국 특허공 개공보소 58-9799호에 개시되어 있다.A safety device in which the operation of the plunger is controlled by a ring cage and an associated control switch is disclosed in Japanese Patent Laid-Open No. 58-9799.

작업자가 프레스의 페달을 시동하였을때 가동금형과 고정금형사이에 피가공물이 아닌 작업자의 손이나 기타장해물이 있을때는 플런저가 시동되기전에 안전장치의 필러가 그것을 검출하여 클러치를 작동시켜서 플런저의 작동을 저지한다.When the operator starts the pedal of the press, if there is a work hand or other obstacle between the movable mold and the stationary mold that is not a work piece, the filler of the safety device detects it before the plunger starts and activates the clutch to operate the plunger. Stop it.

페달의 시동전에 금형사이에서 손이나 기타 장해물을 빼내었더라도 저지작용이 계속되어 플런저의 하강을 저지할 것이다.Even if hands or other obstacles are pulled out between the molds before the pedal is started, the stop action will continue to prevent the plunger from lowering.

페달이 정상위치로 완전히 복귀된 후에야 플런저의 하강이 다시 이어져 정상적인 프레스 작업을 할 수 있게된다.Only after the pedals are fully returned to their normal position will the plunger lower again to allow normal press operation.

그러나, 플런저용 전원의 제어스위치가 연결된 복합링케이지를 사용하는 방식은 프레스기계에 장치하기가 어렵고 장치한후에도 신중한 유지관리를 해야한다.However, the method of using the composite ring cage connected to the control switch of the power supply for the plunger is difficult to install in the press machine and requires careful maintenance even after the installation.

본 고안에 따르면, 가동금형을 저지하는 플런저는 실린더부재와 그것에 신축가능 하도록 맞추어진 피스톤부재, 그리고 실린더부재의 상부에 배치시켜서 피스톤부재를 제동하도록 된 피스톤스토퍼로 구성된다.According to the present invention, the plunger for preventing the movable mold is composed of a cylinder member, a piston member adapted to be stretchable thereto, and a piston stopper disposed on the cylinder member to brake the piston member.

이러한 구조를 갖는 방식의 프레스기계용 안전장치는, 프레스기계의 작업중에 가동금형과고정금형사이에 손가락이나 기타 장해물이 놓여있을때, 피스톤스토퍼가 제동하지 않더라도 피스톤부재를 실린더부재내로 들어가게 하므로, 손가락을 상해로 부터 보호할 수 있다.A safety device for a press machine having such a structure allows a finger to enter the cylinder member even if the piston stopper does not brake when a finger or other obstacle is placed between the movable mold and the stationary mold during operation of the press machine. Protect from injuries

이러한 장해물이 없을때 피스톤부재는 피스톤스토퍼에 의해 제동되며 실린더부재와 함께 하강하여 정상적인프레스 작업을 행하게 된다.When there is no such obstacle, the piston member is braked by the piston stopper and descends together with the cylinder member to perform normal press work.

이하, 본 고안의대표적인 실시예를 도면에 의거하여 상세히 설명한다.Hereinafter, a representative embodiment of the present invention will be described in detail with reference to the drawings.

제2도 및 제3도는 본 고안의 안전장치(1)의 비작동상태를 예시한다.2 and 3 illustrate a non-operational state of the safety device 1 of the present invention.

제2도를 참조하면, 하단이 개구된 실린더부재(2)가 도시되어있다.Referring to FIG. 2, there is shown a cylinder member 2 with an open bottom.

그것은 하단개구로부터 소정의 길이만큼 윗쪽으로 연장되어 하단개구와 동일직경을 갖는 대경부(13)과, 소정의 길이만큼 더 윗쪽으로 연장되어 대경부(13)보다는 직경이 작은 소경부(7)로 구성된다.It extends upwardly by a predetermined length from the lower end opening to have a large diameter portion 13 having the same diameter as the lower opening, and a smaller diameter portion 7 extending upward by a predetermined length and smaller in diameter than the large diameter portion 13. It is composed.

피스톤부재(3)은 대경부(13)과 소경부(7)에서 미끄러지도록 된 각각 다른 규모의 상부와 하부로 구성된다.The piston member 3 is composed of upper and lower portions of different scales, each of which is made to slide in the large diameter portion 13 and the small diameter portion 7.

실린더부재의 대경부(13)은 후술한 낙하스토퍼(14)르 수용하도록 슬롯(20)을 형성시키고, 소경부(7)은 역시 후술할 피스톤스토퍼(5)를 수용하도록 슬롯(15)(16)을 형성시킨다.The large diameter portion 13 of the cylinder member forms a slot 20 to accommodate the drop stopper 14 described later, and the small diameter portion 7 also includes the slots 15 and 16 to accommodate the piston stopper 5, which will be described later. ).

피스톤부재(3)은 실린더부재(2)의 개구저부에서 삽입시키고, 그 사이에 스프링(9)를 수용시킨다.The piston member 3 is inserted at the bottom of the opening of the cylinder member 2 and accommodates the spring 9 therebetween.

피스톤부재(3)이 실린더 부재(2)에서 탈락되는 것은 낙하스토퍼(14)에 의해 저지되며, 피스톤부재는 실린더부재의 슬롯(20)을 통해서 피스톤몸체에 부분적으로 끼워지는 것이 바람직하다.It is preferable that the dropping of the piston member 3 from the cylinder member 2 is prevented by the drop stopper 14, and the piston member is preferably partially fitted to the piston body through the slot 20 of the cylinder member.

슬롯(15)(16)에 의해서 기하학적인 형상을 하는 피스톤스토퍼(5)는 실린더부재(2)의 소경부(7)로 삽입시키고, 스토퍼는 핀(22)를 이용하여 선회가능하도록 실린더부재에 고정시킨다.The piston stopper 5 having a geometric shape by the slots 15 and 16 is inserted into the small diameter portion 7 of the cylinder member 2, and the stopper is pivoted to the cylinder member so as to be pivotable using the pin 22. Fix it.

따라서, 피스톤스토퍼(5)는 핀(22)를 선회축으로하여 그것의 하단(23)이 피스톤부재(3)의 상단(24)을 제동할때까지 선회시킬 수 있다.Thus, the piston stopper 5 can pivot with the pin 22 pivoted until its lower end 23 brakes the upper end 24 of the piston member 3.

실린더부재(2)에서 떨어져 있는 피스톤스토퍼(5)의 단부(28)에는 넓은 슬롯(11)을 수직으로 형성시키고, 피스톤스토퍼작동부재(6)의 스프링(10)으로 밑어서 슬롯(11)에 삽입시킨다.A wide slot 11 is formed vertically at the end 28 of the piston stopper 5, which is separated from the cylinder member 2, and under the spring 10 of the piston stopper operating member 6, Insert it.

피스톤스토퍼 작동부재(6)이 슬롯(11)로 부터 탈락되는 것은 상단에 고정시킨 고정나사(25)에 의해서 방지되며, 그것의 하단(30)은 프레스틀에 고정된 부재(12)와 충돌할 수 있는 위치에 배치한다.The dropping of the piston stopper actuating member 6 from the slot 11 is prevented by the fixing screw 25 fixed to the upper end thereof, and the lower end thereof 30 may collide with the member 12 fixed to the press mold. Place it where you can.

피스톤스토퍼(5)의 슬롯(16)근처에는 상향 돌출부(18)을 형성시키고, 돌출부(18)과 실린더부재(2)의 소경부(7)사이에 형성된 공간에는 스프링(17)을 수용시킨다.The upward projection 18 is formed near the slot 16 of the piston stopper 5, and the spring 17 is accommodated in the space formed between the projection 18 and the small diameter portion 7 of the cylinder member 2.

스프링(10)보다 약한 힘을 가진 스프링(17)은 피스톤스토퍼(5)를 제2도에 도시한 비작동위치로 밑고있게 된다.The spring 17, which has a force weaker than the spring 10, is lowering the piston stopper 5 to the inoperative position shown in FIG.

제3도를 참조하면, 프레스 작업이 개시되어 플런저(도시하지 않음)가 하강함에 따라 본 고안의 안전장치를 부착한 가동금형은 고정금형을 향하여 하강한다.Referring to FIG. 3, as the press work starts and the plunger (not shown) descends, the movable mold with the safety device of the present invention descends toward the stationary mold.

안전장치(1)의 하단, 즉 피스톤부재(3)에 부착된 가동금형의 하단(26)과 고정금형과의 사이에 어떠한 장해물도 존재하지 않으면, 실린더부재(2)와 피스톤부재(3)은 제2도에 도시한 위치에서 함께 하강한다.If no obstacles exist between the lower end of the safety device 1, that is, between the lower end 26 of the movable mold attached to the piston member 3 and the stationary mold, the cylinder member 2 and the piston member 3 It descends together in the position shown in FIG.

가동금형의 하단(26)이 고정금형(4)상의 피가공물인 단추부재(100)과 접하기직전, 피스톤스트퍼 작동부재(6)의하단(30)은 부재(12)의 상면과 충돌할 수 있는 위치에 미리놓이게 된다.Immediately before the lower end 26 of the movable mold comes into contact with the button member 100, the workpiece on the stationary mold 4, the lower end 30 of the piston stripper actuating member 6 may collide with the upper surface of the member 12. Can be placed in advance.

충돌후, 피스톤스토퍼작동부재(6)은 스프링(17)보다 강한 힘을 가진 스프링(10)에 의해서 피스톤스토퍼(5)의 단부(28)을 밀어서 화살표(C)방향으로 회동시키고, 피스톤스토퍼의 하단은 화살표(b)방향으로 선회시킨다.After the collision, the piston stopper operating member 6 pushes the end 28 of the piston stopper 5 by the spring 10 having a stronger force than the spring 17, and rotates it in the direction of the arrow C. The lower end is turned in the direction of arrow (b).

이로인해 피스톤스토퍼의 하단(23)이 피스톤부재(3)의 상단을 제동하는 위치로 이동되어 피스톤부재가 상방으로 미끄러지지 못하도록 한다.As a result, the lower end 23 of the piston stopper is moved to a position for braking the upper end of the piston member 3 to prevent the piston member from sliding upward.

가동금형은 더 하강하여 그것의 하단이 고정금형상의 단추부재와 접하게되고, 플러저에 의한 압력은 피스톤스토퍼(5)를 통해서 피스톤부재로 전달된다.The movable mold is further lowered so that its lower end is in contact with the button member of the stationary mold, and the pressure by the plunger is transmitted to the piston member through the piston stopper 5.

프레스 기계의 통상적인 작업은 이와같은 방법으로 완료된다.The usual work of the press machine is completed in this way.

제4도를 참조하면. 프레스작업도중 가동금형의 하단(26)과 고징금형(4)와의 사이에 손가락(40) 혹은 기타장해물이 존재할 경우에, 그것의 저항력은 피스톤부재(3)을 실린더부재(2)내의 상방으로 미끄러지게 한다.Referring to Figure 4. If a finger 40 or other obstacle is present between the lower end 26 of the movable mold and the high die 4 during the press work, its resistive force causes the piston member 3 to slide upward in the cylinder member 2. Let it go.

미끄럼동작은 피스톤부재(3)의 상단(24)의 일부가 피스톤스토퍼(5)의 측면(29)와 가볍게 접촉하면서 피스톤부재(3)의 상단(24)가 피스톤스토퍼(5)의 하단(23)을 지나 기립한다.In the sliding operation, a portion of the upper end 24 of the piston member 3 is in light contact with the side surface 29 of the piston stopper 5, and the upper end 24 of the piston member 3 is lowered 23 of the piston stopper 5. Stand up).

결과적으로, 피스톤스토퍼(5)는 제3도에 도시한 화살표(b)방향으로 선회하지 못하게되고 스토퍼핀이 부재(12)와 충돌해서 도시한 바와 같이 스토퍼가 스프링(10)을 압축한 후에도 비작동상태로 있게된다.As a result, the piston stopper 5 cannot turn in the direction of the arrow b shown in FIG. 3 and the stopper pin collides with the member 12 so that the stopper can not be pressed even after the stopper compresses the spring 10 as shown. It remains in operation.

스프링(9)는 실린더부재의 대경부와 피스톤부재의 상부사이의 공간에 배열시키는 것이 바람직하다.The spring 9 is preferably arranged in the space between the large diameter portion of the cylinder member and the upper portion of the piston member.

다음 프레스작업을 위해 가동금형을 상측으로 수축시켜 그것의 하단(26)과 손가락 혹은 기타 장해물(40)을 이간시킨 후에 스프링(9)는 피스톤부재를 제2도에 도시한 위치로 돌아가게 한다.The spring 9 causes the piston member to return to the position shown in FIG. 2 after the movable mold is retracted upwards to separate the lower end 26 and the finger or other obstacle 40 for the next press operation.

이상에서는 본 고안을 실시예에 의거하여 설명하였지만, 실시예는 본 고안의 범위를 벗어나지 않는 한도내에서 다양하게 변경하여 실시할 수 있다.In the above described the present invention based on the embodiment, the embodiment can be carried out in various changes without departing from the scope of the present invention.
