Definitions
- the present invention relates to an upper holder device for a press brake.
- a press brake for bending a workpiece includes an upper die mounted on an upper table of the press brake and a lower die mounted on a lower table of the press brake.
- the workpiece is machined by engaging the tip of the upper mold with the groove of the lower mold.
- the upper die used for the press brake is mounted on an upper die holder device mounted on an upper table of the press brake.
- a plurality of upper dies divided in the longitudinal direction must be attached to the upper die holder device.
- the divided upper dies are equally tightened.
- the known U.S. Patent Nos. 6,138,492 shown in FIG. 7 are bent when performing the bending process because the components constituting the mechanism are provided on the front surface of the part where the mold is tightened. The material interfered with the components constituting the above mechanism, and the length of the L portion shown in FIG.
- An object of the present invention is to prevent falling of the divided upper mold according to the above-mentioned prior art, and to facilitate attachment / detachment of the upper mold, thereby enhancing work safety. Purpose of the invention
- the present invention has the following technical means, namely, a mold holding surface in contact with the lower surface of the groove of the split mold and the undivided mold, and a tightening force by the tightening port.
- This is an upper mold holder device that has a mold clamping surface that transmits to the clamping surface of the metal 1 and is provided with a clamp that has a surface in contact with the slope provided on the upper mold holder device main body or a circular surface.
- an upper die holder device body 1 according to the present embodiment is provided with a bolt 3 on an upper table 2 of a press brake. It is installed.
- the upper die holder device main body 1 is provided with a screw portion at a central portion viewed from the front, with which a tightening bolt 6 for tightening a clamp 5 via a spherical washer 4 is screwed. Further, a fastening nut 8 is provided which is rotated via a key 7 provided at the tip of the fastening bolt 6. The tightening nut 8 is provided with a screw portion to which a tightening bolt 11 for tightening the clamp 10 is screwed via a spherical washer 9, and is screwed with the tightening bolt 11.
- the plate 13 is attached to the upper die holder and device body 1 with the bolt 12.
- the tightening nut 8 does not fall off.
- a pin 14 for preventing rotation is provided at an upper portion of the tightening port 11, and a tip end thereof is in a groove provided in the clamp 10.
- a spring 15 and a washer 16 are provided to open between the clamp 5 and the clamp 1 ⁇ and the upper die holder device main body 1.
- the head of the tightening port 6 is provided with a spline that meshes with the spline provided on the leper 17 and engages with each other.
- the rotation position of the lever 17 with respect to the tightening bolt 6 is arbitrary. Can be changed to A port 18 is provided to prevent the lever 17 from coming off.
- the stopper pin 19 of the lever 17 is provided on the clamp 5, and a screw hole 20 is provided so that the lever 17 can be moved slightly.
- the upper die holder device body 1 has a surface 20 that holds the clamp 5 and a clamp 10. It has a slope 21 that receives the force of the above clamping when the upper mold is clamped.
- the clamps 5 and 10 have a surface 22 and a circular surface 23 that are in contact with the surfaces 20 and 21 respectively, and a mold clamping surface 24 and a mold clamping surface 40 below. And a mold holding surface 25 and a slope 26.
- the upper die holder device main body 1 has a pusher 32 that is pressed by a spring 31 and opens between the upper die holder device main body 1 and the clamp 5 or 10. It has a receiving pin 35 which is held by the screw pin 33 and the notch 34 provided in the upper die holder device main body 1 and is rotated downward by pulling out in the longitudinal direction and coming out downward.
- the reper 17 is positioned so as to be in contact with the stopper pin 19, the surface 39 of the upper mold 36 is brought into contact with the surface 38 of the upper mold holder device body 1, and the corners 37 of the mold are used.
- the spring 3 1, the pusher 3 2, the spherical washer 4, and the clamps 5, 10 are clamped by the action of the circular surface 23 provided on the upper part of the clamp 10 and the surface 21 in contact with it.
- the opening between 10 and the surface 38 of the upper die holder device body opens, and the upper die 36 can be inserted between the above-mentioned clamp and the surface 38, and the lower surface of the groove of the upper die 36.
- the gap between the clamp 5 or the clamp 10 and the surface 38 opens as shown by the two-dot chain line in FIG.
- the mold 36 can be easily inserted from below, and the lower surface 27 of the groove of the upper mold 36 can be placed on the mold holding surface 25 of the clamp 5 or the clamp 10.
- the lever 17 If the lever 17 is rotated clockwise in this state, the mounting state is as described above (see FIG. 6), and the upper mold 36 cannot drop. Next, turn the lever 17 counterclockwise until it hits the stopper pin 19, and the gravity of the clamp 5 or the clamp 10 and the upper mold 36 and the above-mentioned inclined surface 21 and the circular surface that comes in contact with it By the action of 23, etc., it becomes as shown in FIG. 2, and the upper mold 36 can be taken out in the longitudinal direction. Also, if the clamp 5 or 10 is lifted slightly by hand, for example, the clamp 5 or 10 becomes as shown by the two-dot chain line, and the upper mold 36 is taken downward and forward. You can get out.
- the upper mold 36 to be attached is mounted to be offset only to the right or left of the upper mold holder device body 1, the lower part of the clamp 5 or the lower part of the clamp 10 where the upper mold 36 is not attached. Since there is nothing to be tightened there, if the above mold is tightened, it will slightly deviate in the direction of the surface 38 of the upper die holder device main body 1.
- attaching the mold 36 pull out the holder 35 where the upper mold 36 is not attached in the horizontal direction, and rotate the screw pin 33 around the rotation center, as shown in FIG.
- the holder 35 When the holder 35 is not used, it is held in the upper die holder device main body 1 by the notch portion 34 and the screw pin 33 provided in the upper die holder device main body 1. Also, place the clamps 5 and 10 in the state of the two-dot chain line shown in Fig. 2, and move the upper mold having no groove in the longitudinal direction to the mold clamping surfaces 40 and 38 of the clamps 5 or 10. By turning the lever 17 clockwise, the upper mold can also be tightened.
- the mold has a mold holding surface and a mold clamping surface, and has an upper mold. It has a circular surface that is in contact with the slope of the holder body.
- the upper mold can be easily attached and detached by the action of the slope, the circular face, the spherical washer, the panel for opening the mold insertion portion, the presser, and the slope provided below the clamp. Became. BRIEF DESCRIPTION OF THE FIGURES
