The hand hemming device equipped with the present invention clamp has a handle 10 to which a hydraulic cylinder operation switch is coupled, a handle fixing device 20 to which one end of the handle 10 is coupled, and the handle fixing device 20 to the side. Hydraulic cylinder 40 is mounted to the coupling body 60 is coupled to the front surface of the hydraulic cylinder (40), the hydraulically actuated, coupled by the connecting body 60 and the hinge 70 and the hydraulic cylinder ( Clamp arm 80 is connected to the piston of the piston 40 is rotated as the piston reciprocates, and coupled to the upper portion of the inner surface of the clamp arm 80 is rotated in the same way according to the rotational movement of the clamp arm 80 The clamp 90 for holding or releasing the work, the guide fixing device 100 is coupled to the upper surface of the clamp 90, and the guide fixing device 100 is coupled with the vehicle body to hemming work Consists of a lower mold jig (110), Since the protrusion 101 of the guide fixing device 100 is guided without being separated from the guide groove 111 of the lower mold 110, a work is performed between the tip of the clamp 90 and the upper surface of the lower mold 110. After placing the water, the operator can grab the handle with one hand, press the switch, and hold the cylinder body with the other hand.

In addition, the guide fixing device 100 has a 'c' shape, the inner surface of the guide fixing device inclined surface 102 is formed, the lower surface of the lower mold jig 110 to correspond to the guide fixing device inclined surface. Since the lower mold support inclined surface 112 is formed, it is formed to easily withstand the pressure by the hydraulic pressure during the handhamming operation.

The hand hemming device of the present invention is a handle 10 coupled to a hydraulic cylinder operation switch, a handle fixing device 20 to which one end of the handle 10 is coupled, and a hydraulic pressure to which the handle fixing device 20 is mounted on the side. The piston of the hydraulic cylinder 40 is coupled by a cylinder 40, a connecting body 60 coupled to the front surface of the hydraulically actuated hydraulic cylinder 40, and the connecting body 60 and the hinge 70. Is coupled to the clamp arm 80 and the piston is rotated as the reciprocating movement, and coupled to the upper portion of the clamp arm 80 is gripped the workpiece if the same rotational movement in accordance with the rotational movement of the clamp arm 80 Alternatively, the clamp 90 for releasing, the guide fixing device 100 coupled to the upper surface of the clamp 90, and the lower fixing part coupled with the guide fixing device 100 to place the vehicle body on the hemming operation. It is composed of a sphere (110).

And the projection 101 of the guide fixing device 100 is reliably guided without being separated from the guide groove 111 of the lower mold jig 110.

Therefore, after placing the workpiece between the upper end of the clamp 90 and the lower mold 110, the operator grasps the handle with one hand and presses the switch, while holding the cylinder body with the other hand to make the operation simple and easy. do.

In addition, the present invention, the guide fixing device 100 has a 'c' shape as a whole, the inner surface of the guide fixing device inclined surface 102 is formed, the lower surface of the lower jig 110 is also the guide fixing device The lower mold support inclined surface 112 is formed to correspond to the inclined surface. Therefore, it can easily withstand the pressure of the hydraulic pressure during the handhamming operation, and play does not occur.

Insert the projection of the hand hemming device into the lower part guide groove of the lower part jig as above, and apply the force of the cylinder body downward of the lower part jig, the inclined surface of the guide fixing device is in contact with the lower part jig inclined surface, This does not occur. In addition, since the lower guide groove is in the upper portion of the lower jig, no play occurs even when a force is applied to the clamp.

In other words, the bilateral feed of the hand hemming device is transferred based on the protrusions and the lower mold guide grooves of the guide fixing device, and is fixed without any play by contacting the inclined surface of the guide fixing device and the lower mold jig in operation.

On the other hand, the weight of the hand hemming device is also lighter than the existing device, so only one side of the handle is installed, so that the operator's work is smooth.

In other words, the present invention is configured so that the hand hemming device is mounted on the lower jig jig for hand hemming work. Hemming the edge of the panel with the device.

And the present invention is the clamp 90 is a vertical section '

Figure pat00004
'It is shaped like a cramp that can hemm a 60 ° exterior panel of a car. When the outer panel proceeds from the hemming work direction A to B, the outer panel of the car starts to hemm at A, the starting point of the clamp, and then folds toward the end of the outer panel in sequence as it proceeds to B. The end of point B is the angle of the final hemming of the vehicle exterior panel. Therefore, at the beginning of the clamp 90 of the outer panel, which is a work piece, it is folded in a sequential order so that 60 ° hemming is completed at the end of the clamp.

And the present invention the clamp 90 is a vertical section '

Figure pat00005
It is formed in the shape, the first hamming introduction part is horizontal shape, the middle part is wavy shape, and the hamming completed part in which the last hamming is 180 ° is also formed in horizontal shape. Therefore, at the beginning of the clamp 90 of the outer panel, which is a work piece, it is folded in a sequential order so that 180 ° hemming is completed at the end of the clamp. Panel angle is measured from the inner panel and folded sequentially in the order of 105 °, 90 °, 60 °, 0 ° (180 ° measured outside).

And the present invention is the clamp 90 is a vertical section '

Figure pat00006
It is formed in a shape, and is a technique of hemming while showing the shape of water droplets on the end of the outer panel during the hemming operation of the cramp. Hemming dripping.

In other words, in order to force the outer panel sequentially in the direction of hemming from A to B, the cramp forms an inclination angle as the cradle progresses from point A to point B, and both points A and B form an inclination angle back and forth. .

In order to form a water droplet on the exterior panel of the vehicle, the water droplet-shaped empty space is located at the rear portion of the points A and B.

In order to press D point, part C presses hydraulic force on the outer panel.

In other words, the pressure point is applied to the outer panel during the operation of the clamp, so that the rear part of the pressing point (panel space formation according to the shape of the clamp) is made according to the shape of the clamp, so that the pressure is not pressed, but only the shape.

Since a force is applied to the clamping point of the clamp, the phenomenon in which the back part of the clamp is formed is called a drop-shaped hemming, which looks like a drop of water.

Therefore, the present invention has a remarkable effect that the clamp is hamming the workpieces sequentially during the hand hemming operation, thus reducing the power required for the hand hamming operation, high dimensional accuracy of the finished hamming, and less defects.

In addition, the present invention, after placing the workpiece between the clamp end and the upper surface of the lower mold, the operator can hold the handle with one hand, press the switch, and the cylinder body with the other hand to facilitate the operation and the weight of the hand hemming device In addition, the inside of the guide fixing device is formed on the inclined surface of the guide fixing device, and the lower surface of the lower fixing tool is also formed on the lower fixing tool inclined surface. There is a significant effect that does not occur.
