Description

Rotary cam press mold capable of pressurizing in a diagonal upward direction

The present invention relates to a rotary cam press mold apparatus capable of being pressed in a diagonal upward direction and more particularly to a rotary cam press mold apparatus which can accurately and equally be positioned on an inner surface of an undercut of a panel, , Which is capable of minimizing the molding process and producing a stable product, and which can be pressed in an upward oblique direction to prevent breakage of the parts by forcibly rotating the rotating cam when the air cylinder is not actuated. .

When a panel having an undercut, which is an inclined portion, is molded, it is impossible to take out the panel by the undercut portion, A rotary cam press device capable of being taken out can be used.

A conventional rotary cam press apparatus includes a base die, a rotation cam that rotates and reciprocates in the base die and forms an undercut portion, an air cylinder that drives the rotation cam, To press the panel in the direction opposite to the rotation cam.

In the conventional rotary cam press apparatus having such a structure, it is possible to form the undercut portion of the panel and the panel can be easily taken out by the reciprocating movement of the rotating cam and the forming steel, and the structure is simple, There are advantages to be able to.

However, since the conventional rotary cam press apparatus has a structure in which the rotary cam rotates and reciprocates along the inner curvature in the annular space, there is a limit in minimizing the wrapping area in order to stably support the rotary cam. For this reason, The distance is limited and the forming direction of the forming steel is only horizontally and downwardly, but is not pressurized in the upward oblique direction, so that the molding process is inevitably increased.

Further, since the rotary cam is operated by driving the air cylinder, the rotary cam is not operated during the air cylinder not operating, which causes a serious problem that the device is damaged.

In addition, since the rotation cam is structured to move along the curvature instead of being fixed by the shaft, there is a problem that a molding error occurs somewhat due to the movement of the rotation cam when the molding steel is pressurized.

In addition, when the undercut portion is formed, the formed steel enters the undercut surface in an oblique direction, thereby causing scratches due to the slip phenomenon between the panels.

The base die 10 is provided with bearings 11 on both sides of its upper portion and both the shaft ends 21 of the rotary cam 20 are coupled to both the bearings 11 so that the rotary cam 20 from the base die 10 And is rotatably installed. The base die 10 is formed with a stand 12 to which the panel P is seated.

The shaft 20 is integrally formed at both ends with a shaft 21 integrally formed on the bearing 11 of the base die 10. The center portion of the rotation cam 20 is projected eccentrically to one side of the shaft 21, (U) shape of the panel (P) which is placed on the upper surface (10).

The rod 31 of the air cylinder 30 is axially coupled to the die and the rod 32 which is projected and retracted from the body 31 is axially coupled to the rotary cam 20. [ Therefore, as the rod 32 is projected and retracted by the driving of the air cylinder 30, the rotary cam 20 rotates and reciprocates with respect to the both shaft ends 21, and the inner side of the undercut (U) So as to be molded.

The forming steel 40 is located on the outer side of the undercut U portion of the panel P so that the undercut U side of the panel P in the direction opposite to the rotation cam 20 Pressure molding. The formed steel 40 is operated by a vertical slide block 13, a horizontal slide block 14 and a slanted slide block 15 provided on the base die 10.

The structure of these slide blocks 13, 14 and 15 will be described in more detail as follows. The vertical slide block 13 reciprocally moves along a vertical rail R1 provided on the base die 10 and the horizontal slide block 14 reciprocates along a horizontal rail R2 provided on the base die 10 And the slanted line slide block 15 reciprocally moves along the oblique rail R3 provided on the base die 10 in the oblique direction. The vertical slide block 13 forms a slope 13 'at one side of the lower portion and the horizontal slide block 14 forms a slope 14' at both sides of the upper slope block 15. The slash slider block 15 has slopes The inclined surface 13 'of the vertical slide block 13 and the one inclined surface 14' of the horizontal slide block 14 are in parallel contact with each other and the inclined surface 15 ' And the other inclined surface 14 'of the horizontal slide block 14 in parallel. Each of the slopes 13 ', 14' and 15 'is provided with a rail R4 so as to perform a smooth sliding movement.

The vertical slide block 13 is connected to the upper mold die so that when the upper die is lowered, the horizontal slide block 14 is moved in the horizontal direction while the vertical slide block 13 is lowered, The slanted line slide block 15 feeds in the oblique direction.

The forming steel 40 is fixed to the upper end of the oblique slide block 15 which is conveyed in the oblique direction and pressurizes the undercut U side of the panel P to form the molded steel 40. Thus, the rotating cam 20 and the formed steel 40, which are pressed by the inner side surface and the outer side surface of the undercut U of the panel P, are pressed in the direction perpendicular to the undercut U surface.

On the other hand, the cam driver 50 is vertically installed at the lower portion of the upper die and is located close to one side of the shaft end 21 of the rotation cam 20. An inclined surface 51 is formed on the lower end of the cam driver 50 and a pad 52 is provided on the inclined surface 51. By providing the pad 52 on the inclined surface 51, wear of the cam driver 50 and the rotary plate 60 is prevented and the impact noise is minimized.

The rotation plate 60 is fixed to the shaft end 21 of the rotation cam 20 and has an inclined surface 61 formed on one side thereof. The rotary plate 60 has a horizontal axial hole 62 formed at the center thereof and is axially coupled to the shaft end 21 of the rotary cam 20. The rotary plate 60 is rotatably coupled to the outer circumference of the shaft 21 and the inner circumference of the shaft hole 62 And is fixed by a key (K) so as to be integrated. Mol, and spline to be integrated. The rotating plate 60 is interfered with the descending cam driver 50 so that the rotating plate 60 and the inclined surface 51 are brought into contact with each other when the cam driver 50 is lowered to forcibly rotate the rotating plate 60, The rotation cam 20 integrated with the rotary shaft 20 also rotates together.

The base die 10 is vertically formed with a support 16 spaced apart from the shaft end 21 of the rotation cam 20 so that the cam driver 50 is rotated between the rotation plate 60 and the support 16 when the cam driver 50 is lowered. (50).

The operation and effect of the rotary cam press mold apparatus which can be pressed in the diagonal upward direction according to the present invention having such a structure will be described in detail.

First of all, the panel P is supplied to the mounting table 12 of the base die 10 and is seated thereon. In order to form the undercut U portion of the mounted panel P, the air cylinder 30 and the upper die Descending.

When the rod 32 of the air cylinder 30 is inserted into the body 31 and pulls the rotary cam 20, the rotary cylinder 20 is rotated about the shaft end 21, (U) portion of the undercut (P).

At the same time, the cam driver 50 is lowered by the lowering type upper die. The cam driver 50 is inserted between the rotation plate 60 and the support base 16 of the base die 10. At this time, since the rotation plate 60 is integrated with the rotation cam 20, the rotation plate 20 rotates together with the rotation of the rotation cam 20, so that the inclined plane 61 of the rotation plate 60 rotates in a vertical state Simultaneously, insertion of the cam driver 50 is performed. At this time, the rotation of the rotary plate 60 and the insertion of the cam driver 60 are performed at the same time. However, by making a time difference, interference between the cam driver 60 and the rotary plate 60, prevent. After the insertion of the cam driver 60 is completed, however, the inclined surface 61 of the rotation plate 60 and the surface of the cam driver 60 are vertically aligned with each other. By the cam driver 60, 20) can no longer rotate. At this time, the center end of the rotation cam 20 is stopped in a state where it is accurately positioned on the inner surface of the undercut U of the panel P.

On the other hand, the vertical slide block 13 is vertically lowered by the lowering die, and the horizontal slide block 14 in contact therewith slidingly slides in the direction of the rotation cam 20 by the vertical slide block 13 descending. Here, the horizontal slide block 14 is moved by the inclined surfaces 13 'and 14' which are in contact with each other. At this time, the rail R4 provided on the inclined surfaces 13 'and 14' is smoothly conveyed. The slanted slide block 15 is upwardly moved along the oblique rail R3 of the base die 10 in the diagonal direction by the horizontal slide block 14 which feeds in the horizontal direction. The oblique slide block 15 is also naturally transported upward by the inclined surfaces 14 'and 15' which are in contact with the horizontal slide block 14. The formed steel 40 provided on the oblique slide block 15 to be conveyed upward presses the outer surface of the undercut U portion of the panel P to be formed and forms it. In this process, the rotating cam 20 generates a repulsive force to rotate in the reverse direction by the impact of the molded steel 40, and the impact is supported by the support 16 to prevent deformation of the cam driver 50.

The rotating cam 20 and the forming steel 40 which press the panel P on the inner and outer surfaces of the undercut U can be formed by pressing the undercut U surface in an upward inclined direction Various molding operations are possible.

When the air cylinder 30 does not operate for any reason, the cam driver 50 descending by the upper die comes into contact with the inclined surface 61 of the rotary plate 60, and the cam driver 50 The slope 51 of the cam driver 50 and the inclined surface 61 of the rotary plate 60 slip and the rotary plate 60 rotates. At this time, the impact is minimized by the inclined surface 51 and the pad 52 formed at the end of the cam driver 50, and the cam driver 50 and the rotation plate 60 minimize damage. When the insertion of the cam driver 50 is completed, the rotation of the rotation cam 20 is stopped because the rotation plate 60 and the cam driver 50 are in close contact with each other. In this state, the above-described vertical slide block 13, the horizontal slide block 14 and the oblique slide block 15 drive the formed steel 40 to press the outer surface of the undercut U of the panel P . If the pad 52 is damaged in this process, maintenance can be performed at a low cost by replacing only the pad 52.

As a result, the cam driver 50 functions to stop the rotation cam 20 exactly at a predetermined position, and to forcibly operate the rotation cam 20 when the air cylinder 30 is not operated. As described above, since the rotation cam 20 is assisted by the cam driver 50 and the rotation plate 60, the damage of a large part that can be caused by the rotation cam 20 that does not rotate when the air cylinder 30 fails .

6 is a side view showing a structure of a stopper block of a rotary cam press mold apparatus which can be pressed in a diagonal upward direction according to another embodiment of the present invention. As shown in the figure, a cylinder 70 is attached to a base die 10 And a stopper block 71 is installed on the rod which is projected and withdrawn from the cylinder 70. The cylinder 70 is installed so as to face the lower space generated by the upward movement of the rotary cam 20. [ Therefore, when the rotary cam 20 is moved upward, the cylinder 70 is driven and the stopper block 71 is inserted into the space generated as the rotary cam 20 moves upward.

By interposing the stopper block 71 at the end of the rotation cam 20 as described above, the stopper block 71 assists the reaction force generated when the forming steel 40 is pressed by the stopper block 71, thereby minimizing damage to other parts.
