Description

The present invention relates to an embossing apparatus, and more specifically, through a corresponding action of a panel support pad fixed to a lower end of an upper die that vertically descends by a press operation, and an embossing die block and a main die block facing the panel supporting pad. The next molding panel is fixed, and the cam slide support base fixed so as to be adjacent to the panel support pad is also lowered, and the cam slide slidably connected with the cam driver fixed to the lower mold is pressed to form the embossing die. Folding molding is performed to bend the end of the primary molded panel that is slid and transferred to the block side. When the panel support pad and cam slide return to the original position according to the lifting action of the upper mold,・ A die fixing block that fixes and supports the lower end of the main die block while being connected to the lower end, and is installed at the lower end of the embossing die block The specified slide block is coupled so as to be able to slide to each other, and at the lower end of the slide block, the lifting die block according to the variable length of the air cylinder and the support of the slide block are managed and the ascending / descending action of the slide block is managed. By installing and configuring the embossing die drive block, of the conventional embossing cam system, folding the panel end according to the punching action of the cam slide in the cam base cam housing, then folding from the die In order to separate the molded panel, it corresponds to the cam slide with a rotary cam system in which the rotary cam corresponding to the cam slide rotates in one direction, or a cam shaft eccentrically coupled to one central side. Swing cam method where the swing cam is swung in one direction through the drive cylinder Compared with the release of locking of the embossing die drive block according to the extension of the length of the air cylinder, both the slide block and embossing die block are transferred to tilt downward from the main die block and die fixing block through the elastic force of the spring. However, the present invention relates to an embossing apparatus that allows an operator to more easily take out a primary molded panel embossed from the embossing die block.

Generally, a panel fixed between a panel support pad 9 fixed to a lower end of an upper die (not shown) vertically lowered by a press operation and a die block (cam housing) 8, 8a, that is, a preceding process. In addition to the embossing operation such as bending the end portion of the panel P that has been primarily molded into a preset form, the panel P that has been embossed is removed from the die block, that is, the cam housings 8 and 8a. As shown in FIG. 1a, an apparatus for separating easily, after embossing for bending the end of the panel P following the punching action of the cam slide 6 within the cam housing 8 of the cam base 7, from the die In order to separate the bent panel P, the rotary cam system 10 in which the rotary cam 11 corresponding to the cam slide 6 rotates in one direction, or as shown in FIG. A swing cam system 20 in which a swing cam 21 corresponding to the cam slide 6 is swing-rotated in one direction through a variable length of the drive cylinder 23 with a cam shaft (swing shaft 11) eccentrically coupled to the central one side as a fulcrum. Is mainly used.

However, among the conventional embossing cam systems as described above, the rotary cam system 10 has a simple overall structure, and the shaft position is simple, but the rotary cam 11 is rotatably provided. Since it is necessary to perform the cylindrical boring process for the arc shape of the inner cam operating groove 8b of the cam housing 8 to be manufactured, the machining operation is very difficult and inconvenient, and the process according to such cylindrical boring process As the cost increases, the disadvantage that leads to the high cost of the whole apparatus through this, and the foreign cam inflow between the rotary cam 11 and the internal cam operating groove 8b of the cam housing 8 cause the rotation of the rotary cam 11 to It is adhered to the outer peripheral surface of the rotary cam 11 and the inner cam operating groove 8b of the cam housing 8, The rotary cam 11 is inserted into the cam operating groove 8b of the cam housing 8 and the adhered foreign material causes the rotary cam 11 to rotate further in the inner cam operating groove 8b of the cam housing 8. In order to fix the rotary cam 11 in an inoperable state or replace parts as described above, the rotary cam system such as disassembling and reassembling all of the embossing apparatus is necessary. Maintenance work for the tenth embossing apparatus is also troublesome and inconvenient, and a tolerance gap is generated between the rotary cam 11 and the cam operating groove 8b of the cam housing 8 by boring. At the time of the embossing work in which the end of the panel P is bent through the punching action of the cam slide 6, the rotary cam 11 is The disadvantage that the quality of the panel P is lowered while being finely pushed into the cam operating groove 8b of the jing 8 and the malfunction of a return cylinder (not shown) connected to the rotary cam 11 through the cam base 7 The rotary cam 11 is frequently damaged due to a collision between the rotary cam 11 and its surrounding parts, and the safety factor according to the damage is greatly reduced. Finally, the cam operating groove 8b of the cam housing 8 There are various problems such as parting selection of the cam housing 8 with respect to the circular rotary cam 11 is very difficult and troublesome.

Further, in the case of the swing cam method 20, the cam housing 8 is internally processed by linear processing in accordance with the shape of the swing cam 21 which is not curved as in the rotary cam method 10, whereby the internal processing operation of the cam housing 8a is performed. Is very simple, and the processing cost according to this is also reduced, leading to a reduction in the cost of the entire apparatus through this, and the correction processing according to the straight line processing inside the cam housing 8a is very much compared with the rotary cam system 10. Since it is simple and has a structure in which foreign substances do not flow in and adhere between the rotary cam 11 and the internal cam operating groove 8b of the cam housing 8 as in the rotary cam system 10, the swing cam 21 corresponding thereto Disassemble the entire embossing device for repairing and replacing parts and parts. Maintenance work for the swing cam type 20 embossing apparatus is also easy and simple, and the cam housing 8a is linearly machined as described above, so that the cam slide 6 At the time of the embossing work for bending the end of the panel P through the punching action, the swing cam 21 is pressed against the cam housing 8a while being in close contact with the cam housing 8a. The quality for molding is improved, and the swing cam 21 by the drive cylinder 23 is swung at a fixed angle with the swing shaft 22 inserted into the swing cam 21 as a fulcrum. The rotation angle is small, the amount of rotation of the swing shaft 22 according to this is small, and as described above The inside of the cam housing 8a and the upper end of the swing cam 21 are formed by linear machining, so that the center of the swing shaft 22 and the parting of the cam housing 8a with respect to the swing cam 21 can be freely selected, but the operation of the swing cam system 20 is performed. The disadvantage that the structure and the operation mechanism are very complicated and difficult as compared with the rotary cam system 10 and that the drive cylinder 23 generates a noise when moving forward and backward, and the twisting action according to the return action of the swing cam 21 However, there are various problems such as a reaction that follows this while acting on the swing shaft 22.

Further, when the drive cylinder 23 is driven, there is a problem that unnecessary resistance is generated because the lower cam driver (not shown) of the embossing part is included.

The present invention, which was devised to solve the above-mentioned conventional problems, is fixed through a corresponding action of a panel support pad vertically lowered by a press operation and an embossing die block and a main die block. The panel support is formed by a relief molding in which a cam slide that is pressed from a cam slide support base that descends the end of the molding panel and is slid and transferred to the embossing die block along the slide surface of the cam slide is bent.

However, it is an object of the present invention to enable an operator to more easily take out the primary molded panel embossed from the embossing die block.

In the case of the present invention, as described above, the locking of the embossing die drive block according to the length extension of the air cylinder is released, and both the slide block and the embossing die block are separated from the main die block and the die fixing block through the elastic force of the spring. Since it has a slide structure such that it is linearly moved so as to incline downward, it is a floating structure that bends the panel end according to the punching action of the cam slide in the cam base cam housing, among the conventional embossed cam systems. Compared to the rotary cam system, in which the rotary cam corresponding to the cam slide is rotated in one direction to separate the bent panel from the die after engraving, the structure is simplified. And reduce manufacturing costs, corrective processing and maintenance are also simple, and use space in the mold There are other object to be able to maximize.

Furthermore, in the case of the present invention, as described above, both the slide block and the embossing die block have a slide structure that is linearly transferred so as to incline downward from the main die block and the die fixing block. As compared with the swing cam method, there is still another object of enabling the parting line of the embossing die block to be simplified.

In order to solve the above-described object, the embossing apparatus of the present invention includes a panel support pad fixed to a lower end of an upper mold that is vertically lowered by a press operation, and an embossing die block and a main die block corresponding to each other. It is a structure that faces the panel support pad and supports 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 following the upward movement of the upper mold. The die fixing block and the slide block installed and fixed to the lower end of the embossing die block are coupled so as to be capable of mutual slide transfer, and the embossing die block and the slide block follow the variable rod length of the air cylinder at the lower end of the slide block. In addition to supporting the above, there is provided an embossing die driving block that controls the ascending / descending action of the slide block. Unlocking the embossing die drive block according to the extension of the cylinder length of the cylinder and releasing the embossing die block from the embossing die block while transferring both the slide block and embossing die block to the downward inclination through the elastic force of the spring. It is characterized in that it is configured so that the formed panel can be taken out more easily.

According to the present invention, among the conventional embossed cam systems, the spring is released together with the unlocking of the embossed die drive block according to the length extension of the air cylinder as compared with the rotary cam system or the swing cam system. Both the slide block and the embossing die block are transferred so as to incline downward from the main die block and the die fixing block through the elastic force of the operator, and the operator takes the primary molding panel embossed from the embossing die block.
