Description

Incidence forming device

The present invention relates to an incidence forming apparatus, and more particularly, a primary forming panel through a corresponding action of a panel support pad fixed to a lower end of an upper die vertically lowered by a press operation, and an incidence die block and a main die block opposed thereto. At the same time, the camslide support base fixed adjacent to the panel support pad is also lowered, and the camslide slide-coupled with the cam driver fixed to the lower die is slid and moved to the angle die block side of the fixed primary molded panel. An incidence molding is formed to bend the end, and the die fixing block for fixing and supporting the lower end of the main die block while being connected to the upper and lower ends of the spring when the panel support pad and the cam slide return to their original positions according to the synergism of the upper die. Fixed slide blocks installed at the bottom of the relief die block for mutual slide transfer At the same time, by installing a relief angle driving block for controlling the lifting and lowering of the slide block along with the support of the relief angle block and the slide block according to the variable length of the air cylinder at the bottom of the slide block, the conventional relief molding cam method Rotary cam corresponding to the cam slide rotates in one direction in order to separate the bent shaped panel from the die after the incidence of bending the panel end according to the punching action of the cam slide in the cam housing of the cam base. In the swing cam method, the swing cam corresponding to the cam slide with the cam shaft eccentrically coupled to one side of the center is swinged in one direction through the driving cylinder. Slide block and embossed die through spring force with unlocking As it will lock both inclined downward from judayi feed block and the die block fixed on the incidence of molding the primary molded panel from the incidence die block at a relief-forming device allows an operator to more easily taken out.

In general, a panel fixed between a panel support pad 9 and a die block (cam housing) 8 and 8a fixed to a lower end of an upper die (not shown) vertically lowered by a press operation, i.e. A device for more easily separating the panel P on which the incidence molding is completed from the die block, that is, the

cam housings

8 and 8a, together with the incidence molding operation such as bending the end of the panel P primarily formed into a shape. As shown in FIG. 1A, the panel is bent from die after the incidence molding to bend the end of the panel P according to the punching action of the cam slide 6 in the cam housing 8 of the cam base 7. Rotary cam system 10 such that the rotary cam 11 corresponding to the cam slide 6 rotates in one direction to separate P), or the cam shaft eccentrically coupled to one side of the center as shown in FIG. (Swing shaft; 22) corresponding to the cam slide 6 Swing cam system 20 such as a length of swing rotation in one direction through the variable of the swing cam 21, the driving cylinder 23 is mainly used.

However, in the case of the rotary cam method 10, the cam housing 8 in which the rotary cam 11 is rotatably installed while the rotary cam method 10 is simple in the overall structure and the axis positioning is also simple. Cylindrical boring of the inner cam operating groove of the inner groove (8b) must be carried out, so machining is very difficult and inconvenient, and the cost of the whole device is increased with the increase of the processing cost due to the cylindrical boring. The outer circumferential surface of the rotary cam 11 according to the rotational action of the rotary cam 11 when foreign matter flows between the rotary cam 11 and the internal cam operating groove 8b of the cam housing 8. Or the rotary cam 11 is adhered to the inner cam operating groove 8b of the cam housing 8 and the rotary cam 11 is caught in the cam operating groove 8b of the cam housing 8 and the rotary cam is caused by the foreign matter. 11 cam In order to fix the rotary cam 11 in the inoperative state or replace parts as described above, the inverted cam forming groove 8b of the inner cam operating groove 8b of the housing 8 is disassembled. And maintenance work on the incidence molding apparatus of the rotary cam method 10, such as to re-assemble and reassemble, boring between the cam operating groove (8b) of the rotary cam (11) and the cam housing (8) Tolerance gaps are generated by machining, and the rotary cam 11 is inserted into the cam operating groove 8b of the cam housing 8 during the relief forming operation of bending the end of the panel P through the punching action of the cam slide 6. The finely pushed down the quality of the indentation of the panel (P) deterioration, and the rotary cam (11) in case of malfunction of the return cylinder (not shown) connected to the rotary cam 11 through the cam base (7) Due to collisions of The breakage of the rotary cam 11 frequently occurs, and thus the safety factor is also greatly reduced. Finally, the cam housing for the rotary cam 11, which is a circular shape of the cam operating groove 8b of the cam housing 8, has a disadvantage. Parting of (8) was very difficult and has various problems, such as hassle.

In addition, in the case of the swing cam method 20, as in the rotary cam method 10, the inside of the cam housing (8) is made by the straight processing according to the shape of the swing cam 21, not curved, thereby the cam housing The internal machining operation of (8a) is very simple and the machining cost is also lowered, thereby reducing the cost of the entire apparatus. The correction processing according to the linear machining inside the cam housing (8a) is applied to the rotary cam method (10). Compared to the above-mentioned, it is very simple and swings against this because it is composed of a structure in which foreign matter is introduced and not adhered between the internal cam operating groove 8b of the rotary cam 11 and the cam housing 8 as in the rotary cam method 10. Maintenance work on the incidence forming apparatus of the swing cam method 20, such as not having to disassemble the entire incidence forming apparatus for fixing or replacing the cam 21 or parts, is also easy and simple, As the inside of the cam housing (8a) is made of a linear processing as shown in the figure, the swing cam 21 is in close contact with the cam housing (8a) during the incidence forming process of bending the end of the panel (P) through the punching action of the cam slide (6). As the rotary cam method (10) is less the phenomena of the jungle, thereby improving the quality of the incidence molding of the panel (P), drive cylinder (23) to the swing shaft 22 inserted into the swing cam 21 to the point The swing cam 21 is rotated at a predetermined angle, but the rotation angle of the swing cam 21 is smaller than that of the rotary cam method 10, thereby reducing the amount of rotation of the swing shaft 22. While the cam housing 8a and the upper end of the swing cam 21 are formed in a straight line, the part of the cam housing 8a with respect to the swing cam 21 and the center of the swing shaft 22 is freely selected. The operating structure and operating mechanism of the swing cam method 20 is much higher than that of the rotary cam method 10. Complicated and difficult disadvantages, noise is generated when the drive cylinder 23 is moved forward and backward, and the torsion effect according to the return action of the swing cam 21 acts on the swing shaft 22, thereby causing recoil. There were various problems such as being.

In addition, when the driving cylinder 23 is driven, there is also a problem that unnecessary resistance occurs because the cam driver (not shown) of the incidence part lower part is included.

The present invention has been made in order to solve the above problems, the lowering of the end of the fixed primary molded panel through the corresponding action of the panel support pad and the depression die block and the main die block vertically lowered by the press operation An incidence molding is performed in which the cam slide pressurized from the cam slide support base and slide-transferred to the incidence die block side along the slide surface of the cam slide is formed. The die fixing block fixedly supporting the lower end of the main die block in the connected state and the slide block fixed to the lower portion of the incidence die block are coupled to each other so as to be slide-moved to each other, and at the same time, the incidence angle of the air cylinder at the bottom of the slide block is variable. The slice with support of the die block and slide block According to the installation and configuration of the incidence die driving block that controls the rise and fall of the block, the incidence die driving block is unlocked according to the length of the air cylinder according to the length of the air cylinder compared to the rotary cam method or the swing cam method. The slide block and the embossed die block are inclined downwardly from the main die block and the die fixing block through the elastic force of the spring, and the object is to enable the operator to easily take out the primary molded panel formed by the embossed die block.

In addition, in the case of the present invention, both the slide block and the relief die block are linearly inclined downwardly from the main die block and the die fixing block through the elastic force of the spring together with the unlocking of the relief die driving block according to the elongation of the air cylinder as described above. Because of the slide structure, the camslide corresponds to the camslide in order to separate the bent panel from the die after the incidence molding, which bends the panel end according to the punching action of the camslide, particularly in the cam housing of the cambase. Compared to the rotary cam method such that the rotary cam rotates in one direction, the structure is simpler, so that the machining and manufacturing cost can be reduced, the modification machining and maintenance are easy, and the other purpose is to maximize the space utilization in the mold. have.

Furthermore, in the case of the present invention, as the slide block and the embossed die block are formed as a slide structure which is linearly inclined downwardly from the main die block and the die fixing block as described above, the parting line of the embossed die block as compared to the conventional rotary cam method or swing cam method. There is another purpose to simplify this too.

According to the present invention, there is provided an incidence molding apparatus according to the present invention, wherein a panel supporting pad fixed to a lower end of an upper die vertically descending by a press operation and a corresponding relief angle die block and a main die block are partitioned from each other. Opposed to and installed at the lower end of the die fixing block and the die fixing block for fixing the lower end of the main die block while being connected to the upper and lower ends of the spring when the panel support pad and the cam slide return to their original positions due to the upward action of the upper die. Fixed slide blocks are coupled to each other so as to be slide-movable, and an indentation die for controlling the lifting and lowering action of the slide block together with the support of the indentation die block and the slide block according to the rod length of the air cylinder at the lower end of the slide block. Installation of the drive block of the relief die driving block according to the extension of the rod length of the air cylinder As the incidence and the slide block through the elastic force of the spring with the king off the die block both the downward inclined conveying it is characterized in that is configured to more easily take out the molded panel from the incidence of incidence die block.

According to the present invention, both the slide block and the relief die block through the elastic force of the spring with the unlocking of the relief die driving block according to the extension of the length of the air cylinder compared to the rotary cam or swing cam of the conventional relief shaping cam method While being inclined downward from the main die block and the die fixing block, there is an excellent effect such that an operator can easily take out the primary molded panel formed by the relief from the relief die block.

In addition, as described above, both the slide block and the relief die block are linearly inclined downwardly from the main die block and the die fixing block by the elastic force of the spring together with the unlocking of the relief die driving block according to the elongation of the air cylinder. Because of this, the cam cam slide and the rotary cam corresponding to the cam slide are separated in one direction to separate the bent panel from the die after the relief of the panel end, which is bent by the punching action of the cam slide, in the cam housing of the cam base. Compared to the rotary cam method such as rotating, the structure is simpler, so it is possible to reduce the machining and manufacturing cost, to modify and to maintain the mold, and to maximize the space utilization in the mold.

In addition, since the slide block and the relief die block have a slide structure that is linearly inclined downward from the main die block and the die fixing block as described above, the parting line of the relief die block is also simplified compared to the conventional rotary cam method or swing cam method. It can also have effects.
