The present invention relates to a press apparatus, and in particular, the cutting machine is interlocked with the upper die of the press apparatus main body is installed to reduce the size of the press apparatus is reduced the press mold cost, the weight is lighter operation of the apparatus The present invention relates to a press apparatus with a cutting machine that significantly improves productivity by significantly improving speed, reducing power consumption and energy costs, and thus significantly reducing production costs of products.

For example, the manufacture of a product such as the E core 21 shown in FIG. 1 used in a transformer is followed by a multi-stage perforation process and a cutting process on a metal plate product material, and such processes are performed in a press apparatus.

For example, the manufacturing process using the press apparatus of the E-core used in the transformer with reference to Figure 2, the press device 10 is composed of a metal plate product material 20 of a predetermined width including the upper die and the lower bolster In the first process, the circular hole 22 for the fixing part of the E core is drilled and the rectangular groove 23, which is a space for winding the coil in the secondary process, is drilled. , B part cutting process is performed.

The cutting process is a process in which the rectangular groove 23 is eventually separated into two E cores. The cutting of the A part is to cut the part in which the rectangular groove 23 is formed so that the rectangular groove 23 is divided into two products. The entire grooved portion is cut from the product material 20 which is the original body.

Because the processing is performed while the high precision of about 1000/1 is required.

However, if the press mold becomes large due to the large size of the product, the productivity is lowered due to the slow speed, and the additional cost of manufacturing such as electric power consumption is increased, while enormous cost is required for the production of the large mold, which in turn increases the cost of the product. There was a problem.

At present, as shown in FIG. 3, when manufacturing a large-size product, the press apparatus 10 ′ is configured to perform only the cutting part B of the three-step process to reduce the size of the press mold. And the cutting of the A portion is a situation that depends on the manual work.

As a result, after the press apparatus 10 'is processed into a semi-finished product 25 as shown in FIG. 4, cutting of the part A is performed by hand.

In the case of the E-core 21 product, it should have a precision of maintaining a tolerance of about one hundred and one hundredths, but the cutting by such a hand can not produce an accurate process, thereby producing a defective product, degrading the quality, and cutting a finger during the work. Safety accidents such as back, frequent, slow and manpower was wasted, there was a problem to significantly reduce the productivity and increase the production cost.

The present invention has been made to solve the above problems,

An object of the present invention is to provide a cutting machine as an attachment to the cutting device to be interlocked with the upper die die body

Press molds are reduced while making finished products on a single flow line, which reduces the press mold cost, and the lighter weight increases the operating speed of the device, significantly improving productivity, and reducing power consumption and energy costs. It is to provide a press apparatus with a cutting machine to significantly reduce the production cost.
