The present invention is a press machine, in which the piercing, bending and trimming work of the industrial cabinet products and the steel cabinet of the computer microwave oven that requires precision with piercing and bending and trimming, at the same time in a set of molds It relates to a composite mold apparatus of a press machine that can be performed.

Conventional presses can bend and pierce or pierce and trim at the same time to process steel cabinets, computers and microwave ovens of industrial equipment products that require precision with piercing, bending and trimming. Since there is no mold device, when processing products with piercing, bending and trimming, the process should be carried out in two to three steps, which not only increases the number of molds, but also lengthens the working process, working time, costs, and costs 2-3 processes. As it is divided and worked by a plurality of molds, there is a defect that the machining dimension is not accurate because the reference point is not constant.

Therefore, the present invention is devised to solve such a conventional drawback and the configuration and operation effects by the accompanying drawings as follows.

On the lower surface of the upper fixing plate 1, a punch fixing plate 2 is mounted to fix the piercing punch 3, the bending punch 4 and the cam 5 at a predetermined position, and then the piercing punch 3 and the cam ( 5), the lower part of the bending punch 4, the upper fixing plate so that the stripper plate 7 attached with the compression rubber 6 for the piercing punch 6 and the compression rubber 6 'for the spring, respectively, can slide up and down ( 1) a fixed plate (1 ') having a compression spring (8) elastically supported on the piercing punch (3) surface between the punch fixing plate (2) and the stripper plate (7) and being mounted to the auxiliary table (9). On the upper surface of the die), the die 11, the die (11) through which the 10 'is drilled is fixed to the outer side, and the cam (in the slider punch guide groove 12 formed in the fixed plate 1' surface). 5) The slider punch 13 is seated so that the sliding guide can be operated by the slide guide. The ring 8 'is elastically supported, and the slider punch stopper 14 is fastened to the outer side of the slider punch 13, and the stopper 1' is prevented from sagging behind the slider punch 13. Subsequently, safety stoppers 15 and 15 'are mounted on one side of the lower surface of the punch fixing plate 2 and the upper surface of the fixing plate 1', respectively, so that the mold cannot be operated more than a predetermined time. As described, reference numeral 16 is a product.

Referring to the effect of the present invention configured as described above are as follows.

When molding a product having a piercing, bending, or trimming using the composite mold apparatus of the press machine of the present application assembled as described above, first, the product 16 is placed on the upper surface of the die 11 as shown in FIG. In the seated state, the upper mold is lowered by a pressram not shown in the drawing, and the compression rubber 6 for the piercing punch and the compression rubber 6 'for the spring, which are attached to the lower surface of the stripper plate 7, are dies. 11) As the upper mold is continuously lowered while the product 16 seated on the surface is pressed, the piercing punch 3 fixed to the punch fixing plate 2 mounted on the upper fixing plate 1 is first stripper plate ( 7) is formed on the die 11 surface while piercing the product 16 while pressing the compression spring 8 elastically supported between the punch fixing plate 2 and pressing the compression rubber 6 for the piercing punch at the same time. As the die scrap groove 10 pierces the scrap produced by piercing the product 16, the bending punch 4, which was lowered at the same time, also has a compression rubber 6 'for the spring as shown in FIG. While pressing down, the product 16 is sandwiched between the die 11 and the bending punch 4 to bend down and the product 16 is bent. Then, the cam 5 which is simultaneously lowered with the piercing punch 3 bending punch 4 In addition, as the upper mold is continuously lowered, the slider punch 13 is moved by horizontally pushing the sliding slider 13 in close contact with the inclined surface of the slider punch 13 by using the inclined surface formed on the lower portion while being lowered. The cutting blade of the slider punch 13 formed in the front portion of the slider punch guide groove 12 formed in the slider punch guide groove 12 formed on the fixed plate 1 'is applied to the die 11 surface while trimming the product 16. Formed scrap The trimmed scraps of the product 16 are pushed into the grooves 10 ', where if the cam 5 is lowered too much during the operation of the cam 5, the slider punch 13 is prevented from sagging backward. The mold may be damaged by colliding with the stopper 14 installed on the side), and the trimming blade of the slider punch 13 may also collide with the bending punch 4 on the upper side. Safety stoppers 15 and 15 'on the upper side of (1') restrict the installation mold from falling below a certain distance, and the piercing punch (3) slider punch after piercing, bending and trimming on the product (16). Compression rubbers (6) and (6 ') are installed so that (13) can slide out of the scrap groove (10) and (10'). Once the piercing, bending and trimming work on the product (16) is finished, Compression soup in the state as shown in Figure 1 as the upper mold is raised The ring (8) and (8 ') return to their original state, respectively, so the circle can repeat the operation as described above and simultaneously pierce, bend and trim the product by a set of molds. As a result, the working process is reduced and the price is reduced, as well as all processing dimensions can be made in one mold, so the reference point is clear and the auxiliary table is attached, which saves setting time when setting the mold. will be.
